[0003] When in use, the hot flue gas from the combustion chamber enters the nozzle and pushes the water in the nozzle to flow to the right. The flowing water drives the turbine to rotate, generating kinetic energy, and the water flows into the water tank through the second pipe. After the high-temperature and high-pressure gas in the cylinder is ejected, the pressure decreases, and the water in the water tank flows into the nozzle through the first pipe again. The water enters the nozzle, pushing the high-temperature gas to be discharged from the exhaust pipe, and the cycle repeats.

[0004] In the actual use of gas engines similar to the above technical solutions in the prior art, it was found that there are areas that need to be improved: after the high-temperature and high-heat gas in the cylinder continuously and reciprocally enters the nozzle, it comes into direct contact with water, which will not only cause a surge in the water temperature in the nozzle, but also the impurities in the high-temperature and high-heat smoke gas will pollute the water quality and affect the circulation and reciprocating use of the water. Utility Model Content

[0005] In view of the shortcomings and defects in the prior art, the purpose of the utility model is to provide a gas engine that solves the problem in the prior art that the high-temperature and high-heat gas in the cylinder continuously and reciprocally enters the nozzle, which not only causes a surge in water temperature in the nozzle, but also impurities in the high-temperature and high-heat smoke gas pollute the water quality and affect the recycling effect of the water.

[0006] In order to solve the above technical problems, the utility model adopts the following technical scheme: a gas engine, including a cylinder, a valve core is rotatably provided in the cylinder, and the valve core is connected to a motor, a combustion chamber is provided on the outside of the valve core on the cylinder, a valve is provided on the lower side of the valve core in the cylinder, an exhaust pipe is provided on the lower outside of the valve on the cylinder, a nozzle is connected to the side of the cylinder away from the motor, the other end of the nozzle is sealed, and a turbine is provided on the inner side of the other end, a water tank is provided above the nozzle, the water tank is connected to the nozzle through a first pipe and a second pipe, the second pipe is provided on the upper side of the turbine in the nozzle, a baffle is slidably provided on the side close to the cylinder in the nozzle, a heat insulation plate is provided on the baffle on the side away from the cylinder, and a filter is detachably provided on the exhaust pipe.

[0007] As a further improvement of the utility model, a slide groove is provided inside the nozzle, a sliding block matching with the slide groove is provided on the baffle, and the baffle is slidably connected with the nozzle via the sliding block.

[0008] As a further improvement of the utility model, a rubber layer is provided on the outer side of the sliding block.

[0009] As a further improvement of the utility model, a waterproof membrane is provided on the side of the heat insulation board away from the cylinder.

[0010] As a further improvement of the utility model, a cooling device is provided in the water tank.

[0011] Compared with the prior art, the utility model has the following advantages:

[0012] 1. A baffle is provided on the side of the nozzle close to the cylinder for sliding, and a heat insulating plate is provided on the baffle. Therefore, after the high-temperature and high-heat gas comes out of the cylinder, the high-temperature and high-heat gas will push the water in the nozzle to move by pushing the baffle, avoiding direct contact between the high-temperature and high-heat gas and the gas, thereby avoiding the smoke particle impurities in the high-temperature and high-heat gas from entering the water, thereby causing the problem of water pollution in the nozzle; in addition, the high-temperature and high-heat gas is separated from the water to avoid causing a sharp increase in the temperature of the water, thereby ensuring the recycling effect of the water in many aspects.

[0013] In addition, a detachable filter is provided on the exhaust pipe, which can filter out impurities in the flue gas when discharging high-temperature and high-heat flue gas, thus preventing impurities from polluting the air.

[0014] 2. By installing a cooling device in the water tank, the circulating water can be cooled to ensure the normal temperature of the water and electricity. BRIEF DESCRIPTION OF THE DRAWINGS
