[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example 1 Please see Figure 1-5 The present invention provides the following technical solution: a counterweight valve plate-type leveling and pressure device for hydropower stations, including an inner cavity 4, the inner cavity 4 being opened inside the gate 2, two first pull rings 1 being fixedly installed above the gate 2, a lifting and adjusting mechanism 3 being provided near the center of the gate 2, and two auxiliary storage mechanisms 5 being provided near the upper part of the gate 2. The lifting and adjusting mechanism 3 includes a lifting plate 31. The lifting plate 31 is provided on the inner side of the inner cavity 4. A valve body 35 is provided on one side of the lifting plate 31. A counterweight valve plate 37 is provided near the center of the valve body 35. Multiple first threaded holes 33 are provided on both sides of the top of the lifting plate 31 near the edge. Multiple first screws 34 are installed on both sides of the gate 2 near the edge by threads. The lifting plate 31 and the valve body 35 are connected by an adjusting component 38.

[0021] Specifically, a first sealing ring 32 is fixedly installed on the outer side of the lifting plate 31 and on the inner side of the inner cavity 4. By adopting the above technical solution, the first sealing ring 32 is used to fill the gap between the lifting plate 31 and the inner cavity 4, thereby improving the sealing performance of the two and preventing water leakage.

[0022] Specifically, a mesh 36 is fixedly installed on the side of the valve body 35 away from the lifting plate 31. By adopting the above technical solution, the mesh 36 is used to intercept debris in the water flow, so as to avoid the occurrence of blockage and stagnation.

[0023] Specifically, a second pull ring 39 is fixedly installed above the counterweight valve plate 37. By adopting the above technical solution, the second pull ring 39 provides a convenient force point for opening and closing the counterweight valve plate 37, simplifies the lifting and lowering operation of the counterweight valve plate 37, and ensures the high efficiency of the opening and closing action of the counterweight valve plate 37 when charging horizontal pressure.

[0024] Specifically, the adjustment assembly 38 includes a fixed cylinder 381. The fixed cylinder 381 is fixedly installed inside the lifting plate 31. A movable cylinder 382 is fixedly installed on one side of the valve body 35 and inside the fixed cylinder 381. The top and bottom of the movable cylinder 382 are provided with multiple second threaded holes 383. The top and bottom of the fixed cylinder 381 are threaded with second screws 384. By adopting the above technical solution, the position of the valve body 35 can be adjusted to a certain extent when the horizontal pressure is applied by the cooperation of the movable cylinder 382 and other structures, so as to better adapt to different water conditions.

[0025] Specifically, a second sealing ring 385 is fixedly installed on the inner side of the fixed cylinder 381 near the valve body 35 and on the outer side of the movable cylinder 382. By adopting the above technical solution, the second sealing ring 385 fills the gap between the fixed cylinder 381 and the movable cylinder 382, ​​thereby improving their sealing performance and preventing water leakage.

[0026] In this embodiment, when the hydropower station needs to use the valve plate type leveling and pressure-relieving device, the two first pull rings 1 on the gate 2 and the second pull ring 39 on the counterweight valve plate 37 in the lifting and adjusting mechanism 3 are connected to the external lifting facilities in advance. Pulling the second pull ring 39 will lift the counterweight valve plate 37, and the valve body 35 will no longer be closed. The water on one side of the gate 2 passes through the partition net 36, the valve body 35, and the moving cylinder 382 and the fixed cylinder 381 in the adjusting assembly 38 to reach the other side of the gate 2, thereby balancing the water pressure on both sides of the gate 2. Then, the two first pull rings 1 are pulled to lift the gate 2 to release water, thus enabling its use.

[0027] When it is necessary to adjust the height and position of the valve body 35 and other structures according to the water conditions, before the gate 2 and other structures are put into use, each of the first screws 34 is turned to disengage from the first threaded hole 33 on the lifting plate 31 in the inner cavity 4. Then, the lifting plate 31 and the valve body 35 and other structures on it are pulled to move to the height corresponding to the water area. Each of the first screws 34 is turned in the opposite direction to connect with the corresponding first threaded hole 33. After the height adjustment is completed, each of the two second screws 384 is turned to disengage from the second threaded hole 383 on the moving cylinder 382. Then, the valve body 35 and the moving cylinder 382 and other structures on it are pulled to move to the position corresponding to the water area. Then, each of the two second screws 384 is turned in the opposite direction to connect with the corresponding second threaded hole 383. After the position adjustment is completed, the first sealing ring 32 and the second sealing ring 385 play a role in ensuring the seal.

[0028] Example 2 The difference between this embodiment and embodiment 1 is that the auxiliary storage mechanism 5 includes a storage box 51. The storage box 51 is fixedly installed on one side of the gate 2, near the top and on both sides of the plurality of first screws 34. The storage box 51 has a storage cavity 54 on its inner side. By adopting the above technical solution, some commonly used tools can be stored when needed through the cooperation of the storage box 51 and other structures, thereby reducing the trouble of staff having to carry tools frequently during daily maintenance and reducing the workload of staff.

[0029] Specifically, a partition 55 is fixedly installed on the inner side of the storage box 51. By adopting the above technical solution, the storage cavity 54 is divided into independent spaces by the partition 55, which can classify and store maintenance tools and accessories, making it easier for staff to quickly find and retrieve them, and further improving maintenance efficiency.

[0030] Specifically, a threaded block 52 is installed on the top of the storage box 51 by means of threads. By adopting the above technical solution, the threaded block 52 is connected to the storage box 51 by threads to achieve the sealing and protection of the storage cavity 54. At the same time, the threaded block 52 is detachable, which makes it convenient for staff to take out and put in the maintenance items inside.

[0031] Specifically, a transparent window 53 is fixedly installed on the inner side of the threaded block 52. By adopting the above technical solution, staff can use the transparent window 53 to observe the storage status of items inside the storage cavity 54, reducing inconvenience for staff.

[0032] In this embodiment, when needed, the staff can unscrew the threaded blocks 52 in the two auxiliary storage mechanisms 5 and put some commonly used tools for daily maintenance into the storage cavities 54 in the two storage boxes 51. The partition 55 serves to separate the space, allowing the staff to store different types of tools separately. Then, the two threaded blocks 52 can be installed back by screws, thereby reducing the trouble of the staff having to carry tools frequently during daily maintenance and thus reducing the staff's workload. The staff can observe the storage status of the items inside the storage cavity 54 through the transparent window 53.

[0033] The working principle and usage process of this invention are as follows: When the hydropower station needs to use the valve plate type leveling and pressure-reducing device, the two first pull rings 1 on the gate 2 and the second pull ring 39 on the counterweight valve plate 37 in the lifting and adjusting mechanism 3 are connected to the external lifting facilities in advance. Pulling the second pull ring 39 will lift the counterweight valve plate 37, and the valve body 35 will no longer be closed. The water on one side of the gate 2 passes through the partition net 36, the valve body 35, and the moving cylinder 382 and the fixed cylinder 381 in the adjusting assembly 38 to reach the other side of the gate 2, thereby balancing the water pressure on both sides of the gate 2. Then, the two first pull rings 1 are pulled, thereby lifting the gate 2 to release water, and thus putting it into use.

[0034] When it is necessary to adjust the height and position of the valve body 35 and other structures according to the water conditions, before the gate 2 and other structures are put into use, each of the first screws 34 is turned to disengage from the first threaded hole 33 on the lifting plate 31 in the inner cavity 4. Then, the lifting plate 31 and the valve body 35 and other structures on it are pulled to move to the height corresponding to the water area. Each of the first screws 34 is turned in the opposite direction to connect with the corresponding first threaded hole 33. After the height adjustment is completed, each of the two second screws 384 is turned to disengage from the second threaded hole 383 on the moving cylinder 382. Then, the valve body 35 and the moving cylinder 382 and other structures on it are pulled to move to the position corresponding to the water area. Then, each of the two second screws 384 is turned in the opposite direction to connect with the corresponding second threaded hole 383. After the position adjustment is completed, the first sealing ring 32 and the second sealing ring 385 play a role in ensuring the seal.

[0035] When needed, staff can unscrew the threaded blocks 52 in the two auxiliary storage mechanisms 5 and put some commonly used tools for daily maintenance into the storage cavities 54 in the two storage boxes 51. The partition 55 serves to separate the space, allowing staff to store different types of tools separately. Then, the two threaded blocks 52 can be installed back by screws, which reduces the trouble of staff having to carry tools frequently during daily maintenance and thus reduces the workload of staff. Staff can observe the storage status of the items inside the storage cavity 54 through the transparent window 53.
