There is provided a vehicle system, including an electromobile having a fuel cell power generator mounted therein, and a predetermined mobile unit jointable to the electromobile, such that cogeneration within the mobile unit can be realized even during the travel of the electromobile. Via a joint section 30, a vehicle 10 including a fuel cell 13 as a source of motive power is jointed to a mobile unit 20 capable of travelling and at least including a storage battery 23 and a water tank 25. The water produced in the fuel cell 13 is recovered by a water recovery section 21 via the joint section 30. The heat produced in the fuel cell 13 is recovered by a heat recovery section 22 via the joint section 30. The recovered water is warmed up with the recovered heat, and thereafter stored in the water tank 25. The hot water stored in the water tank 25 is utilized as hot water to be used for controlling the temperature of the mobile unit 20 or supplied as hot water. Any excess electric power generated by the fuel cell 13 is stored in the storage battery 23, and supplied onto electric wiring within the mobile unit 20.

The invention discloses a photovoltaic support with a cleaning unit, the photovoltaic support includes support columns, support frame and support rods, the support frame is connected with that top endof the support column through a universal joint, the support rod is a telescopic scissors bracket, the angle of the support frame is adjusted through the telescopic scissors bracket, a water spray pipe and a water collecting box are respectively arranged on two opposite sides of the support frame, the water collecting box is arranged as a square box body, the diagonal line of the water collectingbox is fixedly connected to one side of the support frame, a plurality of micro water leakage holes are arranged in the surface of the water collecting box opposite to the water spraying pipe, and awater collecting pipe is connected on the opposite side of the water collecting box and the water spraying pipe, so that the water sprayed from the water spraying pipe is recovered through the inclined two surfaces, and the large-particle dust on the surface of the solar cell panel rolls off along the two inclined surfaces of the water collecting box, so as to ensure that the water pipe is not blocked in the cleaning water recovery process.

The invention provides a condensation water recovery pump mechanical seal cooling device. Cooling circulating water of a cooling circulating water inlet pipe network enters into a buffer tank througha cooling circulating water entrance pipeline; after flowing out from an outlet of the buffer tank, the cooling circulating water enters into a bypass valve and a control valve of a pipeline pressurepump, then enters into the pipeline pressure pump, and the cooling circulating water pressurized by the pipeline pressure pump flows into a distributor; after being distributed by the distributor, thecooling circulating water flows into a plurality of mechanical seal cooling cavities; temperature of the cooling circulating water at the outlets of the mechanical seal cooling cavities is controlledthrough an inlet and outlet control valve group of the mechanical seal cooling cavities; and after flowing out from the outlets of the mechanical seal cooling cavities, the cooling circulating waterenters into a cooling circulating water backwater pipe network through a cooling circulating water backwater pipeline. The condensation water recovery pump mechanical seal cooling device provided by the invention can provide a cooling medium needed for a mechanical seal, consequently realizes reduction of temperature of the mechanical seal in work, and achieves an aim of prolonging service life ofthe mechanical seal.
