[0002] As a clean energy source, hydropower stations are one of the most common ways of generating electricity. The power generation of hydropower stations mainly utilizes the gravitational potential energy of water by the difference in water levels, which is finally converted into electrical energy through mechanical equipment.

[0003] In the generator set of the hydropower station, a water reservoir is needed to store water. An electronic water level gauge needs to be installed inside the water reservoir to monitor the water level in real time. At the same time, a gas pressure sensor needs to be installed to monitor the pressure inside the water reservoir to prevent the internal pressure of the water reservoir from being too high and causing an explosion. When the existing gas pressure sensor is installed, a threaded hole is opened at the top of the water reservoir, and the gas pressure sensor is fixed and installed through the threads and threaded holes on the outer wall of the gas pressure sensor. However, there is a large amount of water inside the water reservoir, so the water will partially evaporate, causing moisture to gather with the threaded connection, causing rust on the threaded connection, affecting the disassembly and replacement of the gas pressure sensor.

[0032] Furthermore, the water reservoir 1 is welded from metal plates, the air pressure sensor 12 is an existing model BSPV002-DV004-A06A1A-S4 pressure sensor, and two plug-in blocks 13 are symmetrically arranged on the outer wall of the detection end thereof, the vertical section of the plug-in block 13 is a right-angled triangle, and its inclined surface faces the side close to the water reservoir 1, and one of the right-angled sides of the plug-in block 13 is welded and fixed to the outer wall of the detection end of the air pressure sensor 12, and the limiting block 14 is a hard plastic block, and a plurality of tooth slots of the limiting block 14 are provided, which are adjacently distributed vertically. The vertical cross-section of the tooth slot is a right triangle. When the plug-in block 13 is inserted into the tooth slot, its inclined surface can fit with the inclined surface of the plug-in block 13. Two limiting blocks 14 are symmetrically arranged. The size of the connecting groove corresponds to the size of the outside of the detection end of the air pressure sensor 12. Two mounting grooves are provided, which are symmetrically provided on both sides of the connecting groove. The bottom end of the limiting block 14 is fixedly connected to the top end of the guide block 15 by gluing. The material of the guide block 15 is the same as that of the limiting block 14. The number of guide grooves corresponds to the number of guide blocks 15. The vertical cross-sections of the guide block 15 and the guide groove are both inverted T-shaped, the size of the guide block 15 is adapted to the size of the guide groove, two groups of driving members are arranged, which are symmetrically distributed on both sides of the mounting tube 21, the connecting rod 16 is made of a stainless steel metal round rod, and the part where the end of the connecting rod 16 contacts the limiting block 14 is fixed by gluing, the sealing ring 20 is annular, and a circular hole is opened in the middle of the sealing ring 20, and the diameter of the circular hole is adapted to the outer diameter of the connecting rod 16, and the outer wall of the sealing ring 20 is fixed to the inner wall of the circular groove by gluing, so that the connecting rod 16 is sealed. The fixing plate 17 is arranged at the end of the connecting rod 16 away from the limiting block 14. The contact part between the connecting rod 16 and the fixing plate 17 is fixed by welding. The fixing plate 17 is disc-shaped. The size of the fixing plate 17 is 1.5 times the diameter of the connecting rod 16. The pull-back spring 19 is sleeved on the outside of the connecting rod 16.

Under the action of the guide block 15 and the guide groove, the limiting block 14 can only move horizontally in a straight line. When the limiting block 14 moves, it drives the connecting rod 16 to move synchronously, and the connecting rod 16 drives the fixed disk 17 to move synchronously.

The water source inside the reservoir 1 flows into the generator 5 and the first turbine 6 through the first connecting pipe 4, and the first turbine is driven by The rotation of the impeller inside the machine 6 drives the rotation of the generator 5. This method is an existing technology for hydroelectric power generation. A pipe for connecting to the high-pressure water hammer pulse unit 7 is arranged at the bottom end of the first water turbine 6. A pipe connected to the second water turbine 8 is arranged on one side of the high-pressure water hammer pulse unit 7. The water flow out of the first water turbine 6 passes through the high-pressure water hammer pulse unit 7, and then flows from the second water turbine 8 to the second water turbine 8, and finally flows back to the inside of the water reservoir 1 through the return pipe 9. When the water level inside the water reservoir 1 is monitored in real time by the water level gauge 11, when the water level inside the water reservoir 1 is too low, the control device 10 will open the solenoid valve of the water replenishment device 3, and let the water source flow into the inside of the water reservoir 1 through the water replenishment pipe of the water replenishment device 3 to replenish the water source. When the water level reaches the set water level, the water level gauge 11 feeds back to the control device 10, and the control device 10 closes the solenoid valve of the water replenishment device 3 to complete the water source replenishment work of the water reservoir 1.
