Environment-friendly and energy-saving boat only powered by water pumping system

Abstract

The invention provides an environment-friendly and energy-saving boat only powered by a water pumping system. The body of the energy-saving boat consists of two piece bodies, the engine room of each piece body is internally provided with at more than one centrifugal pumps, the front side wall and the back side wall of each engine room are provided with a plurality of water inlet holes and water outlet holes, the number of the water inlet holes and the number of the water outlet holes are the same as that of the centrifugal pumps, the water inlet ends of the centrifugal pumps are connected with the water inlet holes by a plurality of water inlet pipes, the water outlet ends of the centrifugal pumps are connected with the water outlet holes by a plurality of water outlet pipes, the water inlet pipes and the water outlet pipes are provided with a plurality of electromagnetic valves, the water inlet pipes between the water inlet ends of the centrifugal pumps and the electromagnetic valves of the water inlet pipes and the water outlet pipes between the electromagnetic valves of the water outlet pipes and the water outlet holes are connected with a plurality of U-shaped water inlet auxiliary pipes, the water inlet pipes between the electromagnetic valves of the water inlet pipes and the water inlet holes and the water outlet pipes between the water outlet ends of the centrifugal pumps and the electromagnetic valves of the water outlet pipes are connected with a plurality of U-shaped water outlet auxiliary pipes, both the water inlet auxiliary pipes and the water outlet auxiliary pipes are provided with the electromagnetic valves, and each engine room is further provided with a power supply which provides power for the centrifugal pumps. The environment-friendly and energy-saving boat is easy to realize the advancing.

Description

technical field [0001] The invention relates to a water vehicle, in particular to an energy-saving ship, and more particularly to an environment-friendly and energy-saving ship that only uses a pumping system as power to drive the ship forward, backward or turn. Background technique [0002] At present, the main way for ships to travel is still to use the internal combustion engine to drive the propeller to rotate to achieve screw propulsion, while the steering of the ship is realized by controlling the rotation angle of the stern rudder through hydraulic transmission. Since the internal combustion engine installed in the engine room of the hull needs to transmit power to the propeller installed outside the engine room through the transmission device, if the dynamic seal between the power shaft and the engine room is not very good, both fuel and lubricating oil may leak. Possibility of water pollution, the exhaust gas will also affect the air quality of the cabin, and the ro...

Problems solved by technology

Chinese utility model patent 200720148175.2 discloses a ship auxiliary steering thrust device. The device is provided with a hanger on the left and right outer sides of the front of the hull and on the left and right outer sides of the rear of the hull. The hanger is provided with a water pump. The outlet end of the water pump is connected to a rotating water spray pipe with a water-sealed bearing. By adjusting the water spray direction of the water spray pipe, the hull can be turned conveniently and quickly. The existence of the frame will still increase the resistance of the hull operation, and the rotation of the water spray pipe needs to overcome the resistance of sea water. The power of the water spray pipe rotation is provided by the rotating shaft of the motor installed in the hanger. Not only the kinetic energy loss is large, but also there is a need to solve The problem of dynamic sealing, in addition, the pump can only pump water from one direction, if it pumps water and sprays water in one direction at the same time, the hull cannot move
