The invention discloses an underwater vehicle carrying type in-situ deep sea water sampler and relates to the field of in-situ deep sea substance sampling. The underwater vehicle carrying type in-situdeep sea water sampler comprises a water sampling bottle, a triggering device and two plugging devices, wherein an air vent and a water outlet nozzle are formed in the water sampling bottle, the plugging devices are arranged at openings at two ends of the water sampling bottle, and the triggering device is arranged at the side face of the water sampling bottle and is connected with the plugging devices. The underwater vehicle carrying type in-situ deep sea water sampler has the beneficial effects of being simple in structure and flexible in operation; as a ring like floating ball floating onthe water sampling bottle is taken as a start terminal so as to start the water sampling bottle conveniently; the water sampling bottle is plugged by two plugs from two ends by utilizing an elastic rope, so as to reduce disturbance of an original sample collecting object and improve the effectiveness of a sample; and the underwater vehicle carrying type in-situ deep sea water sampler is suitable for the operation of carrying of underwater unmanned tethered submersible, manned untethered submersible and the like, and is high in collecting efficiency.

The invention discloses auxiliary equipment for heat dissipation and dust removal of a notebook computer. The equipment comprises a rack, and two storage cavities which are symmetrical front and backare fixedly connected to the end wall of the left side of the rack. According to the equipment, a tail holding rack fixes a computer body, and a vaccum sucker is combined to fix a computer screen, sothat the notebook computer can be stably placed on equipment, accidental collision is prevented, the screen unfolding degree can be automatically adjusted through the vacuum sucker, the screen is turned off when no person uses the notebook computer , and a gear and rack structure is used and matched with a trigger device to conduct front-back reciprocating motion on a fan, so that the heat radiation area is enlarged, and heat radiation efficiency is increased; and meanwhile, the bottom of the computer can be lifted through the hydraulic rod, so that the sweeping wheel can be matched with a wire wheel to conduct bottom dust removal treatment, dust is collected through the fan, and the heat dissipation effect of the computer is greatly enhanced.

The invention discloses a device for preventing an elevator car from accidental movement and a control method. The device comprises electric rail clamping devices which are symmetrically mounted at the top of an elevator car, contact wheels in tight contact with vertical surfaces of guide rails, and an encoder which is fixed at one end of the contact wheel. When a car door and a floor door are in an open state, whether an electric safety device of each door leaf is in an off state or not is identified; a contact type triggering device starts to enter a working state; the encoder accurately acquires a rotating angle of the contact wheel and calculates a movement distance of the contact wheel on the vertical surfaces of the guide rails; the state of the elevator car is judged through judging the movement distance of the elevator car. The device disclosed by the invention has the beneficial effects that the movement prevention device is mounted at the top of the elevator car, and the transformation of each floor station is avoided. so that the modification cost is reduced; furthermore, an electric safety switch of each door leaf of the elevator door is used for judging the device for preventing the elevator car from the accidental movement; when it is determined that the elevator door accidentally moves, the device is started up, and the guide rails are tightly clamped by the electric rail clamping devices, so that the elevator car is prevented from further accidental movement and a dangerous shearing accident is effectively avoided.
