Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort belong to the scope of the present application.

[0020] Please refer to Figures 1-8 An embodiment of the present application is a water turbine governor, which comprises a governor body 1, a water inlet pipe 2 fixed on the top of the governor body 1, a water outlet pipe 3 fixed on the left side of the governor body 1, a runner 4 rotatably installed on the right side of the governor body 1, a control module 5 fixed on the outer wall of the water inlet pipe 2, a temperature sensor 6 arranged on the control module 5, an electrical connection between the temperature sensor 6 and the control module 5, a filter plate 8 fixed on the inner wall of the water inlet pipe 2, a protective shell 7 fixed on the inner wall of the water inlet pipe 2, and an ice crushing device arranged inside the water inlet pipe 2 to crush ice layers inside the water inlet pipe 2.

The connecting spring 13 is fixed on the bottom of the connecting column 19, and the bottom of the connecting spring 13 is fixed on the inner wall of the fixed seat 11. The inclined cone 15 is fixed on the outer wall of the connecting column 19. The ice crushing rod 16 penetrates through the outer wall of the rotating cylinder 10 in a sliding connection manner. The end point of the ice crushing rod 16 is provided with an inclined surface.

[0023] When the temperature outside is too low, the liquid in the water inlet pipe 2 will reach the freezing point, so that the temperature sensor 6 senses low temperature and sends an electrical signal to the control module 5, so that the control module 5 can control the motor 9 to start, so that the motor 9 can drive the rotating cylinder 10 to rotate counterclockwise, so that the rotating cylinder 10 can drive the cutter 17 on the ice breaking rod 16 to rotate counterclockwise, so that the cutter 17 can cut the ice crystals before the ice layer is completely frozen and solidified, and when the rotating cylinder 10 rotates, it can drive the extrusion rod 12 to rotate, so that when the extrusion rod 12 rotates to contact the inclined surface of the triangular plate 14, the extrusion rod 12 will extrude the inclined surface of the triangular plate 14, so that the triangular plate 14 can be moved upward under the extrusion force, so that the connecting spring 13 is stretched, the triangular plate 14 drives the connecting column 19 to move upward, and the connecting spring 13 is stretched, when the connecting column 19 moves upward, the inclined surface of the inclined surface cone 15 extrudes the inclined surface of the ice breaking rod 16, so that the ice breaking rod 16 can move outward from the rotating cylinder 10 under the extrusion force, so that the reset spring 18 is compressed, and when the extrusion rod 12 rotates to not contact the triangular plate 14, the triangular plate 14 will not be extruded, because the connecting spring 13 is in a stretched state, so that the connecting spring 13 can drive the connecting column 19 to move downward, so that the connecting column 19 can drive the inclined surface cone 15 not to extrude the inclined surface of the ice breaking rod 16, because the reset spring 18 is in a compressed state, so that the ice breaking rod 16 can be reset, when the ice breaking rod 16 is extruded from the rotating cylinder 10, the ice breaking rod 16 can extrude the ice layer on the inner wall of the water inlet pipe 2, and when the ice breaking rod 16 is reset, the next crushing operation can be performed, and the crushed ice falls on the filter plate 8, and the ice is melted by the impact of the water flow in the water inlet pipe 2 and is discharged from the filter plate 8.

[0024] Please refer to Figures 1-8On the basis of the above embodiment, in another embodiment of the application, the top of the filter plate 8 is provided with an auxiliary device for turning the ice layer, and the auxiliary device is provided with a reciprocating device for improving the rapid melting of the ice layer. The auxiliary device comprises an L-shaped support rod 201, a fixed disc 202, a support block 205, a bent rod 204, a rotating rod 203, a rubber wheel 206, a cutting knife 207 and a turning rod 208. The L-shaped support rod 201 is fixed at the top of the fixed seat 11, the fixed disc 202 is fixed at the end of the L-shaped support rod 201 away from the fixed seat 11, the L-shaped support rod 201 penetrates through the triangular plate 14 and is fitted at the penetration position, the bent rod 204 penetrates through the outer wall of the rotating cylinder 10, the support block 205 is fixed at the end of the bent rod 204, the support block 205 is fixed to the inner wall of the rotating cylinder 10, and the support block 205 can support the bent rod 204, the rotating rod 203 is rotatably installed on the outer wall of the bent rod 204, and the rotating rod 203 penetrates through the rotating cylinder 10 and is rotatably connected at the penetration position, the outer wall of the bent rod 204 is slidably connected with the inner wall of the cutting knife 207, the rubber wheel 206 is fixed on the outer wall of the rotating rod 203, and the outer wall of the rubber wheel 206 is fitted with the bottom of the fixed disc 202.

[0025] When the rotating cylinder 10 rotates, the bent rod 204 and the rotating rod 203 are driven to rotate, the bent rod 204 drives the cutting knife 207 to rotate, the cutting knife 207 can further crush the ice layer falling on the top of the filter plate 8, so that the relatively large ice layer is crushed, and the problem that the ice block falling on the filter plate 8 is too large and the water flow cannot melt the ice block efficiently is solved. When the bent rod 204 and the rotating rod 203 rotate, the rubber wheel 206 can rotate on the fixed disc 202, the rubber wheel 206 can rotate under the friction, the rotating rod 203 drives the turning rod 208 to rotate, the crushed ice slag on the filter plate 8 can be turned, the turning action lifts the crushed ice slag, the ice slag is more easily washed away with the water flow, and the risk of clogging of the filter plate 8 is reduced.

[0026] The reciprocating device comprises an inclined block 302, a protruding block 301, a return spring 303 and a friction block 304. The inclined block 302 is fixed on the side wall of the cutting knife 207, the protruding block 301 is fixed on the outer wall of the rotating rod 203, one side of the return spring 303 is fixed on the end of the bent rod 204, the other side of the return spring 303 is fixed on the inner side of the cutting knife 207, and the friction block 304 is fixed on the outer wall of the cutting knife 207.

[0027] When the rotating rod 203 rotates, the convex block 301 can extrude the inclined surface of the inclined block 302, so that the inclined block 302 is extruded away from the fixed seat 11, the cutting knife 207 is driven away from the fixed seat 11, and the return spring 303 is compressed. When the convex block 301 rotates to be out of contact with the inclined block 302, the cutting knife 207 can be reset by the return spring 303. Through the back-and-forth movement of the cutting knife 207, the cutting knife 207 can rotate and crush the ice block on the top of the filter plate 8 while moving back and forth, solving the problem that the cutting knife 207 is stuck due to the hardness of the ice block. Through the back-and-forth movement of the cutting knife 207, the cutting knife 207 moves back and forth on the ice block when it contacts and cuts the ice block, so that the ice block can be cut by the cutting knife 207 with greater force, thereby cutting the harder ice block; The friction block 304 is a ceramic matrix composite material with good wear resistance, and the rotating rod 203 is a metal material. When the cutting knife 207 moves back and forth, the friction block 304 can move back and forth on the outer wall of the rotating rod 203, so that the rotating rod 203 can heat up due to the friction force, and the rotating rod 203 can heat up when rotating in the ice slag, thereby accelerating the melting of the ice slag; When the rotating cylinder 10 rotates counterclockwise, the rotating cylinder 10 drives the bent rod 204 and the rotating rod 203 to rotate counterclockwise. When the bent rod 204 rotates counterclockwise, the bent rod 204 drives the cutting knife 207 to rotate counterclockwise, which has the effect of further crushing the ice residues and the like on the filter plate 8. When the rotating rod 203 rotates counterclockwise, the rubber wheel 206 rotates on the bottom of the fixed disc 202, and the outer wall of the rubber wheel 206 is tightly attached to the bottom of the fixed disc 202. When the rubber wheel 206 rotates on the bottom of the fixed disc 202, the rubber wheel 206 rotates under the extrusion force, and the rubber wheel 206 drives the rotating rod 203 to rotate clockwise. The rotating rod 203 drives the turning rod 208 to rotate clockwise. When the rotating rod 203 rotates clockwise, the convex block 301 rotates clockwise. When the convex block 301 rotates to contact the inclined surface of the inclined block 302, the inclined block 302 extrudes the cutting knife 207 away from the rotating cylinder 10, and the return spring 303 is compressed. When the convex block 301 rotates to be out of contact with the inclined block 302, the return spring 303 is compressed, and the return spring 303 drives the cutting knife 207 to reset. While the cutting knife 207 rotates, the cutting knife 207 moves back and forth, which has the effect of better crushing the ice on the filter plate 8. While the cutting knife 207 moves back and forth, the friction block 304 moves back and forth on the outer wall of the rotating rod 203, which has the effect of heating the rotating rod 203 and accelerating the melting of the ice residues.
