[0018] Working principle: The flange of the sewage pipe is fixedly connected to the flange interface 110 on one side of the shell 100, and sewage is introduced. The sewage enters the valve from the flange interface 110 on one side of the shell 100, and the controller 324 is started at the same time. The controller 324 starts the grinding motor 206, and the grinding motor 206 drives the eccentric cam 205 to rotate. The eccentric cam 205 rotates to squeeze the slider 201. The slider 201 moves to one side under the squeezing of the eccentric cam 205. At the same time, the slider 201 squeezes the spring, and the slider 201 drives the movable grinding frame 200 to slide to one side. The movable grinding frame 200 slides relative to the grinding plate 202, and the sewage and impurities are discharged from the movable grinding frame 20 0, when the eccentric cam 205 rotates to the farthest distance from the axis of the grinding motor 206 and contacts the slider 201, the slider 201 moves in the opposite direction under the action of the spring, and the slider 201 drives the movable grinding frame 200 to reset, and the impurities are accumulated in the gap between the rectangular through hole of the movable grinding frame 200 and the surface of the grinding plate 202 until the movable grinding frame 200 is completely reset, and the above movement process of the movable grinding frame 200, the slider 201, and the eccentric cam 205 is repeated, and the distance between the movable grinding frame 200 and the grinding plate 202 changes periodically, and the impurities in the sewage are ground and pass through the eccentric wheel 212 together with the water flow; When the grinding motor 206 is started, the vibration motor 214 is also started by the controller 324. The vibration motor 214 drives the heat-conducting shaft 210 to rotate via the adapter column 211, and the heat-conducting shaft 210 drives the eccentric wheel 212 to rotate. The rotation of the eccentric wheel 212 generates vibration, which is transmitted to the surroundings through the housing 100, and cooperates with the movable grinding frame 200 and the grinding plate 202 to increase the crushing amplitude, thereby improving the crushing effect and reducing the probability of blockage. When the surface of the eccentric wheel 212 contacts the surface of the elastic metal plate 213, the elastic metal plate 213 is elastically deformed. When the surface of the eccentric wheel 212 leaves the elastic metal plate 213, the elastic deformation of the elastic metal plate 213 is restored, and the vibration is generated and transmitted through the sewage flow, which helps to arouse the impurities and debris deposited at the bottom, reduces the probability of blocking the valve, and improves the sewage discharge effect. When sewage flows to the water wheel 403, the water flow pushes the water wheel blades 404, and then the water wheel blades 404 drive the water wheel 403 to rotate axially. The water wheel 403 drives the generator 400 to rotate through the water wheel shaft 402. The rotation of the generator 400 generates current, which is transmitted to the electromagnet assembly 503 through the wire. After the electromagnet assembly 503 is energized, it generates electromagnetic force, attracts the valve core head 502 to drive the valve core 500 to slide toward the front. After the valve core 500 slides toward the front, the water seat 107 is connected with the flange interface 110 on the other side, and the sewage flows from the water seat 107 to the flange interface 110 on the other side, thereby discharging the valve. The faster the sewage flows, the greater the current generated by the generator 400, the greater the displacement amplitude of the valve core 500, and the greater the opening and closing amplitude of the valve, so as to adapt to sewage discharge environments with different flow rates; When sewage is frozen, the movable grinding frame 200 and the grinding plate 202 and the eccentric wheel 212 are unable to move due to the influence of ice, which results in the grinding motor 206 and the vibration motor 214 being blocked from rotating. The internal current of the grinding motor 206 and the vibration motor 214 increases, and the grinding motor 206 and the vibration motor 214 continue to heat up. The temperature of the internal temperature sensor of the grinding motor 206 and the vibration motor 214 fed back to the controller 324 continues to rise. The built-in temperature sensor of the controller 324 senses that the outside temperature has fallen below zero degrees, and determines that the valve is abnormal due to the freezing of sewage. The controller 324 controls the electric heating pipe 311 and the power on. The heater 321 and the electric heating pipe 311 are started, generating heat to melt the frozen ice around the movable grinding frame 200. As the frozen ice gradually melts, the movable grinding frame 200 and the eccentric wheel 212 gradually resume their actions and begin to crush the remaining ice cubes. The temperatures of the grinding motor 206 and the vibration motor 214 gradually drop to normal temperatures after the movable grinding frame 200 and the eccentric wheel 212 resume their normal actions. When the temperatures of the grinding motor 206 and the vibration motor 214 return to the normal range and the built-in temperature sensor of the controller 324 senses that the external temperature is above zero degrees, the controller 324 controls the electric heating pipe 311, the upper electric heater 321, and the electric heating pipe 311 to be turned off. When the sewage freezes and causes the valve to become abnormal, the water wheel 403 cannot rotate, which in turn causes the generator 400 to be unable to rotate and generate electricity, and the valve core 500 cannot move, so the valve remains closed to prevent foreign matter from entering the valve and affecting the normal state of the valve.
