A release device for the debris-blocking float of a hydroelectric power station

Abstract

This utility model relates to the field of water conservancy engineering, specifically disclosing a release device for debris-blocking floats in hydropower stations. It includes a left mounting base, a right mounting base, a left anchor post, a right anchor post, a guide wheel, and a release module. A main traction rope is installed between the left and right anchor posts, and a secondary traction rope is installed between the guide wheel and another right anchor post. Several floats are connected in series by the main and secondary traction ropes. The main and secondary traction ropes operate in an alternating tension mode: when the secondary traction rope is tensioned, the left end of the main traction rope is not under stress, and the release module assists the left end of the main traction rope to disengage from the left anchor post. Subsequently, the winch continuously releases the secondary traction rope, and the floats, limited by the secondary traction rope, float freely along the water flow direction, temporarily not obstructing the water flow, thus preventing the main traction rope from breaking due to overload. This solution, through the coordinated operation of the winch and the release module, enables remote control.

Description

Technical Field

[0001] This utility model belongs to the field of water conservancy engineering, and specifically relates to a device for releasing the floating buoy of a hydropower station. Background Technology

[0002] The existing debris-blocking device consists of several pontoons and ropes connecting all the pontoons, with both ends of the ropes fixed to the banks. Floating debris is intercepted by the pontoons and anchored at their edges. Due to the impact of the water flow, the ropes and pontoons are often arranged in a curved pattern. When the water flow is below 8000 m³ / s, conventional ropes can withstand the impact of the water flow and ensure the safe anchoring of the pontoons; however, when the water flow exceeds 9000 m³ / s (this condition often corresponds to floods), to ensure safety, one end of the rope must be loosened to prevent the rope from breaking due to overload—at this time, the rope and pontoons will swing freely with the water flow.

[0003] However, during floods, the currents are rapid, and the method of workers operating the hoists and releasing the hooks on the shore poses extremely high safety risks. Therefore, a more ideal solution is to achieve automatic rope release through remotely controlled equipment. Utility Model Content

[0004] The purpose of this invention is to provide a remotely controllable device.

[0005] To achieve the above objectives, this utility model provides a release device for the debris-blocking floats of a hydropower station, comprising: a left mounting base and a right mounting base located on the left and right sides of a river channel. The left mounting base is equipped with a left anchor post, a guide wheel, and a release module. The right mounting base is equipped with two right anchor posts. A main traction rope is connected between the left anchor post and one of the right anchor posts. The main traction rope is detachably connected to the left anchor post and fixedly connected to the right anchor post. Several floats are connected in series on the main traction rope for interception. The debris floating on the water surface is connected to a secondary traction rope between the guide wheel and the other right anchor post. The secondary traction rope connects all the buoys in series. A winch is installed on the left side of the mounting base in the river channel. The winch is connected to the secondary traction rope, and the secondary traction rope is fixedly connected to the right anchor post. The release module is used to release the connection between the main traction rope and the left anchor post. Both the winch and the release module include a motor, a wireless transceiver, and a control board, and both the winch and the release module are electrically controlled.

[0006] As an improvement to the above scheme, the left anchor post is a rotating structure that is thick at both ends and narrows at the waist, and the end of the main traction rope is provided with a ring and is sleeved on the left anchor post through the ring.

[0007] As an improvement to the above solution, the release module includes a lift and a lever connected to the movable end of the lift. The lift controls the lever to rise and fall, and when the lever lifts the ring, the main traction rope disengages from the left anchor post.

[0008] As an improvement to the above scheme, a pair of guide wheels are provided, and the secondary traction rope passes between the two guide wheels before being connected to the winch.

[0009] As an improvement to the above solution, the side of the buoy is provided with four connecting rings, and every two connecting rings on the same side form a pair, which are used to thread the main traction rope and the secondary traction rope respectively.

[0010] This utility model has the following beneficial effects:

[0011] The main traction rope and the secondary traction rope adopt an alternating tension working mode: when the secondary traction rope is in a tensioned state, the left end of the main traction rope is not under force. At this time, the release module will assist the left end of the main traction rope to disengage from the left anchor post; then the winch continuously releases the secondary traction rope, and several floats float freely along the water flow direction under the limiting action of the secondary traction rope, temporarily not obstructing the water flow, thereby avoiding the main traction rope from breaking due to overload.

[0012] After the floodwaters recede, the winch is activated to retrieve the secondary traction rope, pulling several pontoons back to their initial positions. Workers then reattach the left end of the main traction rope to the left anchor post. This system, through the coordinated operation of the winch and the release module, enables remote control. During floods, workers do not need to untie the main traction rope on the shore, significantly improving operational safety. Attached Figure Description

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0018] In the description of this invention, "several" means one or more, "multiple" means two or more, "greater than," "less than," and "exceeding" are understood to exclude the stated number, while "above," "below," and "within" are understood to include the stated number. Where the terms "first," "second," and "third" are used for descriptive purposes and to distinguish technical features, they should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the sequential relationship of the indicated technical features.

[0019] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. The embodiments of this utility model will now be described based on its overall structure.

[0020] Reference Figures 1 to 3This utility model discloses a release device for debris-blocking floats in a hydropower station, comprising: a left mounting base 21 and a right mounting base 22 located on the left and right sides of a river channel 10, both mounting bases being concrete structures. The left mounting base 21 is provided with a left anchor post 31, a guide wheel 33, and a release module 51. The right mounting base 22 is provided with two right anchor posts 32. A main traction rope 41 is provided between the left anchor post 31 and one of the right anchor posts 32. The main traction rope 41 is detachably connected to the left anchor post 31, and is fixedly connected to the right anchor post 32. Several floats 43 are connected in series on the main traction rope 41 to intercept floating debris on the water surface. A secondary traction rope 42 is provided between the guide wheel 33 and the other right anchor post 32, and the secondary traction rope 42 connects all the floats 43 in series. A winch 34 is installed on the side of the left mounting base 21 in the river channel 10. The winch 34 is connected to the secondary traction rope 42, and the secondary traction rope 42 is fixedly connected to the right anchor post 32. The release module 51 is used to release the connection between the main traction rope 41 and the left anchor post 31. Both the winch 34 and the release module 51 include a motor, a wireless transceiver, and a control board, and both the winch 34 and the release module 51 are electrically controlled.

[0021] As an improvement to the above solution, the left anchor post 31 is a rotating structure that is thicker at both ends and narrower at the waist. The end of the main traction rope 41 is provided with a ring, which is then fitted onto the left anchor post 31. Figure 2 As shown, when the main traction rope 41 is under force, the ring cannot move upward and will only stay at the waist of the left anchor post 31.

[0022] As an improvement to the above solution, the release module 51 includes a lifting platform and a lever connected to the movable end of the lifting platform. The lifting platform controls the lifting of the lever, and when the lever lifts the ring, the main traction rope 41 disengages from the left anchor post 31. Figure 2 As shown, the lever is U-shaped. When the lever is raised, it simultaneously lifts the ring, which eventually detaches from the left anchor post 31. To prevent the feet of the release module 51 from obstructing the ring's detachment, the release module 51 is positioned slightly upstream (located in...). Figure 1 (below the middle).

[0023] As an improvement to the above solution, a pair of guide wheels 33 are provided, and the secondary traction rope 42 passes between the two guide wheels 33 before connecting to the winch 34. This design facilitates the sliding of the secondary traction rope 42.

[0024] As an improvement to the above solution, the float 43 is provided with four connecting rings on its side. Two connecting rings on the same side form a pair, which are used to thread the main traction rope 41 and the secondary traction rope 42, respectively. This design avoids friction between the two traction ropes when they are alternately contracted.

[0025] The main traction rope 41 and the secondary traction rope 42 operate in an alternating tension mode: when the secondary traction rope 42 is tensioned, the left end of the main traction rope 41 is not under tension, and at this time, the release module 51 will assist the left end of the main traction rope 41 to disengage from the left anchor post 31; subsequently, the winch 34 continuously releases the secondary traction rope 42, and several floats 43 float freely along the water flow direction under the limiting action of the secondary traction rope 42. Figure 1 As shown, the water flows from bottom to top, and several floats 43 float upwards, temporarily not obstructing the water flow, thus preventing the main traction rope 41 from breaking due to overload. At this time, the right ends of the main traction rope 41 and the secondary traction rope 42 are under stress.

[0026] After the floodwaters recede, the winch 34 starts to retrieve the secondary traction rope 42, pulling several floats 43 back to their initial positions. Workers then reattach the left end of the main traction rope 41 to the left anchor post 31. Finally, the winch 34 releases a small amount of the secondary traction rope 42, allowing the main traction rope 41 to be subjected to the impact of the water flow again. This solution, through the coordinated operation of the winch 34 and the release module 51, enables remote control. During floods, workers do not need to untie the main traction rope 41 on-site, significantly improving operational safety.

[0027] The foregoing description of specific exemplary embodiments of the present invention is for illustrative and explanatory purposes. These descriptions are not intended to limit the present invention to the precise forms disclosed, and it will be apparent that many changes and variations can be made in accordance with the foregoing teachings.
