The automatic oil level balancing and compensating device for refrigerating compressor includes one replenishing oil box with a connected gas pipe, the first solenoid valve and one exhaust valve; and one replenishing oil pipe and one second solenoid valve connected via a connecting oil pipe to the bottom of the crankshaft box in the compressor. The gas pipe has the outer end connected to the upper part of crankshaft box in the compressor and located over the oil level line of the crankshaft box, and the inner end in the lower part of replenishing oil box and with height determining the absolute height of the oil level inside the crankshaft box. Two solenoid valves are controlled by the controller for simultaneous opening or closing. The present invention can balance and compensate the oil level inside the crankshaft box of compressor automatically, and is suitable for single compressor or united compressors.

The invention provides a convenient windscreen wiper wiping angle measuring apparatus and measuring method thereof. The measuring apparatus comprises a visible laser transmitting probe and a cambered dial. The visible laser transmitting probe is provided with a fixing clip fixing the visible laser transmitting probe and the output shaft of a windscreen wiper. The cambered dial is provided with a bracket fixing the cambered dial. In the measuring process, the visible laser transmitting probe reciprocates along with the output rotating shaft of the windscreen wiper to be tested and the light beam emitted from the visible laser transmitting probe moves on the cambered dial. The circle center axes corresponding to the cambered surface of the cambered dial is superposed with the output rotating shaft of the windscreen wiper to be tested so that the distance between the light beam emitted from the visible laser transmitting probe and the same horizontal line of the dial is the same, consequently the measurement can be more accurate. The measuring apparatus has the advantages of simple structure, convenient and accurate measurement and extensive application range and provides convenience for engineer to measure the wiping angle of the windscreen wiper more conveniently in any situation.

The invention specifically relates to a metal drip line installed on the upper part of the protruding structure of the wall to prevent the wall and the protruding structure from hanging and polluting. It includes two attachment sheets, and the opening angle α between the two attachment sheets is 0° <α<180°; the intersecting ridges of the two attachment sheets are connected with an overhanging piece extending along the horizontal direction, and the edge of the overhanging piece relative to the intersecting ridge is connected with a deflector extending below the overhanging piece; The diversion angle β between the guide sheet and the overhanging sheet is α≤β<180°; the lengths of the guide sheet, the attachment sheet and the extension sheet are equal. The overhanging sheet extending along the horizontal line can change the direction of rainwater flow, keeping the rainwater away from the facade of the protruding structure on the wall, and then fall along the guide sheet. The deflector angle β is α≤β<180°, so that the deflector is located in the area between the two limit positions where sagging occurs: the horizontal position parallel to the wall surface protruding the facade of the structure and coplanar with the deflector , so as to prevent the phenomenon that the wall and the protruding structure of the wall are hanged and polluted by rainwater.

The invention provides an oil returning system for a multi-compressor parallel-connection unit. Under the working condition that two compressors are in parallel connection, oil tanks of each compressor (1) are connected through an oil balance pipe (3); the axis (OO') of each oil balance pipe (3) is lower than the lowest oil level line (PP') in an oil mirror (4); the upper portions of oil surfaces of the oil tanks of each compressor (1) are connected with each other through an air balance pipe (2); under the working condition that three compressors are in parallel connection, an air outlet (16) of each compressor (1) is connected with an oil separator (7), the upper end of each oil separator (7) is connected with a condenser, the lower end of each oil separator (7) is connected with an oil storing device (8), and each oil storing device (8) is connected with a ball cock type oil level controller (6); a pressure adjusting valve (10) is connected between the corresponding oil storing device (8) and a low-pressure pipe of the parallel-connection unit; and according to the high-pressure oil returning system for the parallel-connection unit, the air outlet (16) of each compressor (1) is connected with an oil separating and storing device (20), the upper end of each oil separating and storing device (20) is connected with the corresponding condenser, and the lower end of each oil separating and storing device (20) is connected with an electronic type oil level controller (19).

The invention relates to a drum-type ship with a drum-type outer ship body. The outer ship body and an inner ship body are movably connected through transverse peripheral rotating mechanisms. The outer ship body can transversely rotate along with wind and waves on the water and by internal power. A horizontal line of the inner ship body can always be perpendicular to an earth gravity line. The drum-type ship is mainly characterized in that the interior of the cross section of the outer ship body which contacts with the water is a standard circle, and the outer ship body can perform circular motions relative to the inner ship body; the outer ship body and the inner ship body are movably connected through various transverse peripheral rotating mechanisms. The drum-type ship has the advantages that adverse effects of external environments on the interior of the ship is eliminated, and sailing time periods of the ship is expanded; sailing manners of the ship is flexible and diversified, sailable water areas for the ship is expanded, and the ship can transversely land to leave the water areas along a ramp.

One embodiment of an orbital sign assembly, allowing for attachment to and full pivot or orbit capability of the attached signage around a horizontal run of span wire or other support member. Any one traffic signage is supported from a horizontal run of a span wire or other support member by a orbital sign assembly comprising a sign bracket (10) with attachment points at opposing ends and center, a pivot attachment (2) allowing 360 degree pivoting of the sign, which adjoins the sign bracket (10) to the a cable saddle (1) which contains two pivot attachment rails (3) for limiting side to side movement of the pivot attachment on its track. Conventional U-bolts (5) are located within the cable saddle and are used to clamp down to the span wire while still allowing traffic signal cables to be inserted through a cable slot (4) within the cable saddle (1). A cant tilt slot (11) is located on the sign bracket for leveling signage.

The invention relates to the technical field of building decoration, in particular to a ground fine leveling technology. The ground fine leveling technology comprises the following steps that horizontal lines with the same height are popped up on the four walls, close to the ground, of a room; a first drawing pin is pressed on the horizontal line of one wall, and a fine line is bound on the firstdrawing pin; cement mortar is laid in a right-angle triangular region at one corner of the room firstly; the cement mortar is embedded into a plurality of tile strips before the cement mortar is solidified, a smooth glaze surface of each tile strip faces upwards and is not stained, and the tile strips as much as possible are located on the same straight line; and before the cement mortar is solidified, one end of the fine line is pulled to move along the horizontal lines of the three walls without fixing the first drawing pin, meanwhile, the positions of the tile strips are manually adjusted so that the fine line can completely scratch the smooth glaze surfaces of all tile strips and then waiting for the solidification of the cement mortar. According to the ground fine leveling technology,the step of cake plastering is canceled, a replacement method which is simpler and easier to operate and high in efficiency is adopted, so that the construction time of ground fine leveling is greatly reduced.
