The connection terminal 702 is sleeved on the top of the signal terminal 5. A rotating sleeve 703 is fixed on the outer wall of the connector 701, and a pressure ring 704 is fixed at the bottom of the rotating sleeve 703. The pressure ring 704 slides in the card holder 4 and overlaps with the top of the support component 13. A locking rod 705 is fixed on both sides of the pressure ring 704, and the card slot 14 is designed in an L-shape. The locking rod 705 is engaged in the protruding part on one side of the inner wall of the card slot 14. The connector 701 drives the locking rods 705 on both sides of the pressure ring 704 to be engaged from the opening at the top of the card slot 14. By holding the rotating sleeve 703 and rotating the connector 701 clockwise, the pressure ring 704 drives the two locking rods 705 to be engaged on one side of the inner wall of the L-shaped card slot 14, which serves to lock the position of the pressure ring 704 and the connector 701, so that the connector 701 will not be dislodged from the card holder 4. A support frame 10 is fixed to the bottom of the card holder 4. A conductive assembly 11 is fixed inside the support frame 10. The signal terminal 5 is located inside the conductive assembly 11. The conductive assembly 11 includes an air guide seat 111, which is fixed to the inner wall of the support frame 10. The air guide seat 111 has an annular design and a piston ring 112 slides in its internal cavity. The top of the piston ring 112 overlaps with the edge of the bottom of the connector 701. Several first springs are fixed between the piston ring 112 and the internal cavity of the air guide seat 111. 113, the piston ring 112 is supported by the elastic force of multiple first springs 113, so that the piston ring 112 moves upward and simultaneously lifts the connector 701. As the piston ring 112 rises in the cavity inside the air guide seat 111, the air guide seat 111 can draw air from the inside of the sealing assembly 12 through multiple air guide tubes 123, so that the sealing assembly 12 can gradually shrink and return to its original shape until the sealing assembly 12 is separated from the connector 701, which facilitates the separation of the signal terminal 5 from the connection terminal 702. The sealing assembly 12 is fixed on the support frame 10 and the inner wall of the card seat 4, and comprises an inflation ring 121. The outer wall and the bottom of the inflation ring 121 are fixed to the inner wall of the card seat 4 and the top of the support frame 10 respectively.

The gas inside the air guide seat 111 is guided into the inflation ring 121 through the plurality of air guide pipes 123, so that the inflation ring 121 expands and drives the plurality of sealing rings 122 to contact the outer wall of the plug-in connector 701, until the signal terminal 5 is completely inserted into the inside of the connecting terminal 702. At this time, the sealing ring 122 is tightly attached to the outside of the plug-in connector 701, so that the signal terminal 5 and the connecting part of the connecting terminal 702 are completely sealed, preventing the connection between the signal terminal 5 and the connecting terminal 702 from loosening and causing dust and water stains to enter the connection; The bottom end of the signal transmission assembly 7 is inserted into the signal terminal 5 and the outer wall is in contact with the inner wall of the sealing assembly 12. The inner wall of the card seat 4 is fixed with a support assembly 13 above the sealing assembly 12. The support assembly 13 comprises a fixed ring 131 fixed above the inner wall of the card seat 4. A plurality of second springs 133 are fixed on the fixed ring 131. The top of the plurality of second springs 133 is fixed with a push ring 132 which is slidingly connected in the card seat 4. The top of the push ring 132 is overlapped with the bottom of the pressing ring 704. The push ring 132 is supported by the elastic force of the plurality of second springs 133, so that the push ring 132 pushes the plug-in connector 701 upward through the pressing ring 704, so that the connecting terminal 702 at the bottom of the plug-in connector 701 is away from the signal terminal 5, so as to pull out the plug-in connector 701 from the card seat 4; The top of the support assembly 13 is overlapped with the outer wall of the signal transmission assembly 7. Two clamping grooves 14 are formed on the top of the card seat 4. The two ends of the signal transmission assembly 7 are clamped in the two clamping grooves 14 respectively.

[0016] The bottom of the water turbine governor 2 is fixed with a support frame 15, ventilation holes are formed in the two sides of the support frame 15, when the water turbine governor 2 works, the heat generated can be introduced into the support frame 15 from the bottom, the ventilation holes formed in the two sides of the support frame 15 can dissipate the heat from the two sides, the bottom of the support frame 15 is fixedly connected with a heat exhaust assembly 16, the heat exhaust assembly 16 comprises a U-shaped frame 161, the U-shaped frame 161 is fixed to the bottom in the control box 1, a plurality of heat exhaust holes 162 are formed in the U-shaped frame 161, the bottom of the support frame 15 is fixed with the top of the U-shaped frame 161, dustproof nets 163 are respectively installed on the front and back of the U-shaped frame 161, the front and back of the control box 1 are hingedly installed with cabinet doors 17 corresponding to the front and back positions of the water turbine governor 2, the cabinet doors 17 are provided with observation windows, the bottom of the support frame 15 is of a transparent design, so that the heat generated by the water turbine governor 2 can enter the inside through the heat exhaust holes 162 in the U-shaped frame 161 and then be exhausted from the dustproof nets 163 on the front and back of the U-shaped frame 161, because the U-shaped frame 161 supports the water turbine governor 2, the problem of heat dissipation dead angle does not exist, the water stains are prevented from entering the control box 1 by the bottom exhaust mode, and the dustproof nets 163 can block the dust from entering the control box 1.

[0017] The working principle of the present application is as follows: When the water turbine governor 2 in the control box 1 works, the heat generated can be introduced into the support frame 15 from the bottom, the ventilation holes formed in the two sides of the support frame 15 can dissipate the heat from the two sides, and the bottom of the support frame 15 is of a transparent design, so that the heat generated by the water turbine governor 2 can enter the inside through the heat exhaust holes 162 in the U-shaped frame 161 and then be exhausted from the dustproof nets 163 on the front and back of the U-shaped frame 161, because the U-shaped frame 161 supports the water turbine governor 2, the problem of heat dissipation dead angle does not exist, the water stains are prevented from entering the control box 1 by the bottom exhaust mode, and the dustproof nets 163 can block the dust from entering the control box 1, while ensuring the normal work of the water turbine governor 2, the heat generated can be effectively exhausted from the control box 1; When the water turbine governor 2 is disconnected from the controller 9 in the control box 1, hold the rotating sleeve 703 outside the plug-in connector 701 and press down, so that the rotating sleeve 703 drives the compression ring 704 and the two clamping rods 705 to move downward, the compression ring 704 then extrudes the multiple second springs 133 below through the push ring 132, and the clamping rod 705 is separated from the protruding part on one side of the inner wall of the clamping groove 14, and then rotate the rotating sleeve 703 counterclockwise, so that the compression ring 704 drives the two clamping rods 705 to rotate, until the clamping rod 705 is tightly attached to the inner wall of the clamping groove 14, at this time the push ring 132 is supported by the elastic force of the multiple second springs 133, so that the push ring 132 lifts the plug-in connector 701 upward through the compression ring 704, so that the connecting terminal 702 at the bottom of the plug-in connector 701 is away from the signal terminal 5, and the locking state of the plug-in connector 701 by the clamping seat 4 is released, in this process, the piston ring 112 is supported by the elastic force of the multiple first springs 113, so that the piston ring 112 is lifted upward while lifting the plug-in connector 701, because the piston ring 112 rises in the cavity inside the gas guide seat 111, the gas guide seat 111 can draw air from the inside of the inflation ring 121 through the multiple gas guide pipes 123, so that the inflation ring 121 can gradually shrink and recover to its original state, until the inflation ring 121 drives the multiple sealing rings 122 to separate from the outer wall of the plug-in connector 701, and the signal terminal 5 is separated from the connecting terminal 702, then pull out the signal transmission assembly 7 upward, and the signal transmission assembly 7 can be removed from the clamping seat 4; When the water turbine governor 2 is connected with the controller 9, the holding sleeve 703 inserts the connecting terminal 702 at the bottom of the plug-in connector 701 into the card holder 4, and the edge at the bottom of the plug-in connector 701 is extruded to the piston ring 112 in the process of pressing the plug-in connector 701, so that the piston ring 112 moves downward in the cavity inside the gas guide base 111 and extrudes the gas, the gas inside the gas guide base 111 is guided into the inflation ring 121 through the gas guide pipe 123, the inflation ring 121 is inflated and drives the sealing ring 122 to contact the outer wall of the plug-in connector 701, until the signal terminal 5 is completely inserted into the connecting terminal 702, at this time the sealing ring 122 is tightly attached to the outside of the plug-in connector 701, so that the signal terminal 5 and the connecting terminal 702 are completely sealed, in this process, the plug-in connector 701 drives the clamping rod 705 on both sides of the pressure ring 704 to be clamped into the opening at the top of the card slot 14, at the same time the pressure ring 704 slides into the card holder 4 and extrudes the second spring 133 below through the push ring 132, the card holder 4 limits the position of the pressure ring 704, keeps the plug-in connector 701 moving downward in the vertical direction, improves the stability of the connection between the signal terminal 5 and the connecting terminal 702 below, prevents the signal terminal 5 and the connecting terminal 702 from being deformed due to the deviation angle, and then the holding sleeve 703 rotates the plug-in connector 701 clockwise, so that the pressure ring 704 drives the two clamping rods 705 to be clamped on one side of the inner wall of the L-shaped card slot 14, after the holding sleeve 703 is loosened, the push ring 132 is supported by the elastic force of the second spring 133, so that the push ring 132 drives the clamping rod 705 to move upward and be clamped into the protruding part on one side of the inner wall of the card slot 14, which achieves the purpose of locking the position of the pressure ring 704 and the plug-in connector 701, so that the plug-in connector 701 cannot be separated from the card holder 4, preventing the water turbine governor 2 from being affected by external force to cause the signal terminal 5 and the connecting terminal 702 to be loose.
