Background With the increase of global population, the development of socioeconomic performance and the change of consumption modes, the demand of water and the water consumption are continuously increased, and the fresh water resources are very limited, so that the water consumption dilemma is solved in various countries and mainly depends on the sea water resources. The method for extracting the seawater by adopting the economic, efficient, energy-saving and environment-friendly method has an important effect on solving the problem of difficult water consumption. Currently, many seawater pumps for pumping seawater are electric pumps, diesel pumps, etc., and these types of pumps have the disadvantages of high energy consumption and environmental pollution. Disclosure of Invention The utility model provides the seawater pump to solve the technical problems of high energy consumption and environmental pollution of the existing seawater pump. In order to achieve the above purpose, the present utility model adopts the following technical scheme. A seawater pump, comprising: A ocean current turbine including a turbine body and a first drive shaft; An air compressor comprising a compressor body, an air flow output end and a second transmission shaft, wherein the second transmission shaft is in transmission connection with the first transmission shaft, and The air pump comprises an air pump body, an air flow input end, a water flow input end and a water flow output end, wherein the air flow input end is communicated with the air flow output end through an air circuit. When the seawater pump is installed, the ocean current turbine is required to be placed below the sea surface, the water flow input end is communicated with seawater through the water pipe, and the water flow output end is communicated with the water supply pipe network through the water pipe. Therefore, the utility model utilizes the seawater to drive the ocean current turbine so as to drive the air compressor to operate, the air compressor transmits the compressed air to the air pump, and the air pump pumps the seawater into the water supply network without consuming electric energy, so that the energy is not consumed, and the environment is not polluted. In some embodiments, the gas paths are connected in parallel with a branch gas path, the branch gas path comprises a first branch gas path, a gas storage tank and a second branch gas path which are sequentially communicated according to the gas flow direction, and the first branch gas path and the second branch gas path are respectively provided with a first valve and a second valve. Thereby, the air storage tank can store redundant compressed air and supplement the air flow to the air channel when needed. In some embodiments, the first valve is a pressure reducing valve and the second valve is a pressure increasing valve.
