Technical Field

[0001] This utility model relates to the field of hydropower station equipment technology, specifically a hydropower station gate opener. Background Technology

[0002] In large-scale water supply and drainage, water conservancy and hydropower projects, they are generally composed of multiple hydraulic structures such as water discharge system, power generation system, and irrigation system. When raising and lowering various large and medium-sized cast iron gates and steel gates, due to the large weight of the gates, it is difficult to achieve fast and accurate raising and lowering by manpower to open or close the gates.

[0003] A search revealed a hydropower station gate hoist disclosed in Chinese Patent Publication No. CN 213448363 U. This gate hoist includes: a traveling mechanism, a frame, a crossbeam, and a track trolley; the traveling mechanism is capable of traveling on a preset track of the hydropower station, the frame is located on the traveling mechanism, the crossbeam is installed above the frame, and the track trolley is capable of moving on the crossbeam; the traveling mechanism includes: a front traveling unit, a rear traveling unit, and a traveling connector, the front traveling unit and the rear traveling unit being connected together along the front-rear direction of the track via the traveling connector; the frame is detachably mounted on the traveling connector; wherein, both the front traveling unit and the rear traveling unit include two traveling modules arranged along the front-rear direction of the track, and the two traveling modules are fixedly connected together by a traveling frame.

[0004] The gate hoist described in the aforementioned patent still has certain shortcomings. In actual operation, the wire ropes used in existing hydropower stations are subjected to large tensions and are often exposed to humid air and dust. This causes water and dust to accumulate in the gaps between the rope strands, which can easily lead to internal rusting, reduce its strength and flexibility, and greatly increase the risk of breakage, posing a significant safety hazard. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a hydropower station gate hoist, which solves the problem that existing winch-type gate hoists used in hydropower stations suffer from significant tension during operation. The steel wire ropes used for winching are frequently exposed to humid air and dust, causing water and dust to accumulate in the gaps between the rope strands, leading to internal rusting, reduced strength and flexibility, and a significantly increased risk of breakage, posing a substantial safety hazard.

[0006] This utility model provides the following technical solution: a hydropower station gate hoist, including a support base frame, a winding roller is provided at the top of the support base frame, a steel wire rope is wound on the winding roller, a side support plate is provided on the side of the top of the support base frame, a drive motor box is provided on the other side of the top of the support base frame, the side of the winding roller is rotatably connected to the side support plate through a rotating shaft, the drive motor box is rotatably connected to the side of the winding roller through a drive shaft, two bottom support plates are symmetrically provided on both sides of the bottom end of the support base frame, and a winding protection assembly is provided at the bottom end of the support base frame;

[0007] The winding protection assembly includes a limiting and fixing strip fixedly installed at the bottom end of the support base. The limiting and fixing strip has a central through hole in its middle. Two guide blocks are symmetrically arranged at the top of the central through hole. Two mounting frames are symmetrically arranged inside the central through hole. Several sponge boards are arranged on the sides of each mounting frame. Two limiting through holes are symmetrically opened on the inner wall of the central through hole. An abutting connecting rod is inserted into each limiting through hole. One end of the abutting connecting rod passes through the limiting through hole and is fixedly connected to the mounting frame. The other end of the abutting connecting rod passes through the limiting and fixing strip. An abutting spring is sleeved on the abutting connecting rod. One end of the abutting spring is connected to the rod body of the abutting connecting rod. The other end of the abutting spring is connected to the outer wall of the limiting and fixing strip. Two oil storage tanks are symmetrically arranged on both sides of the limiting and fixing strip. Each oil storage tank has an oil inlet.

[0008] Preferred technical solution 1: Several side mounting holes are symmetrically opened on both sides of the limiting and fixing strip, and several oil delivery pipes are evenly arranged on the side of the oil storage tank.

[0009] Preferred technical solution 2: The oil delivery pipe extends through the side mounting hole to the side of the sponge plate, and the steel wire rope passes through the central through hole and passes through the side of the sponge plate.

[0010] Preferred technical solution 3: The side of the top of the guide block is arc-shaped and inclined.

[0011] This solution can guide the wire rope as it passes through the central through hole, reducing direct friction between the wire rope and the side wall of the central through hole.

[0012] Preferred technical solution four: The side of the mounting frame is adhesively connected to the sponge board.

[0013] This solution makes the connection between the sponge board and the mounting frame more secure.

[0014] Preferred technical solution five: A baffle is provided at the end of the abutting connecting rod.

[0015] This design makes the contact spring more securely mounted on the contact connecting rod.

[0016] Compared with the prior art, the present invention provides a gate hoist for a hydropower station, which has the following advantages:

[0017] (1) This utility model provides a winding protection component on the bottom side of the support base. The winding protection component has a central through hole in the middle of the limiting and fixing strip. Two sponge plates are symmetrically arranged in the central through hole. The sponge plates are soaked with lubricating oil transported in the oil storage tank. When the wire rope moves through the central through hole, the lubricating oil stored in the sponge plate can coat the surface of the wire rope, thereby forming a layer of grease protective film on the surface of the wire rope to prevent moisture and air from contacting it, thus playing a role in rust prevention and greatly reducing the risk of breakage. It is safer and more reliable to use. Attached Figure Description

[0024] Please see Figures 1-4 ,

[0025] Example 1: A gate hoist for a hydropower station includes a support base frame 1, a winding roller 2 is provided at the top of the support base frame 1, a steel wire rope 5 is wound on the winding roller 2, a side support plate 3 is provided on the side of the top of the support base frame 1, and a drive motor box 4 is provided on the other side of the top of the support base frame 1. The side of the winding roller 2 is rotatably connected to the side support plate 3 through a rotating shaft, and the drive motor box 4 is rotatably connected to the side of the winding roller 2 through a drive shaft. Two bottom support plates 6 are symmetrically provided on both sides of the bottom end of the support base frame 1, and a winding protection assembly 7 is provided at the bottom end of the support base frame 1.

[0026] The winding protection assembly 7 includes a limiting and fixing strip 701 fixedly installed at the bottom of the support base 1. The limiting and fixing strip 701 has a central through hole 702 in the middle. Two guide blocks 703 are symmetrically arranged at the top of the central through hole 702. Two mounting frames 704 are symmetrically arranged inside the central through hole 702. Several sponge boards 705 are arranged on the sides of each mounting frame 704. Two limiting through holes 706 are symmetrically opened on the inner wall of the central through hole 702. A contact connecting rod 707 is inserted into each limiting through hole 706. One end of the contact connecting rod 707 passes through the limiting through hole 706 and is fixedly connected to the mounting frame 704. The other end of the contact connecting rod 707 passes through the limiting and fixing strip 701. A contact spring 708 is sleeved on the contact connecting rod 707.

[0027] One end of the contact spring 708 is connected to the body of the contact connecting rod 707, and the other end of the contact spring 708 is connected to the outer wall of the limiting fixing strip 701. Two oil reservoirs 709 are symmetrically arranged on both sides of the limiting fixing strip 701. Each oil reservoir 709 has an oil inlet 710. Several side mounting holes 711 are symmetrically opened on both sides of the limiting fixing strip 701. Several oil delivery pipes 712 are evenly arranged on the side of the oil reservoirs 709. The oil delivery pipes 712 extend through the side mounting holes 711 to the side of the sponge plate 705. The steel wire rope 5 passes through the central through hole 702 and passes through the side of the sponge plate 705.

[0028] Example 2: The difference between this example and Example 1 is that the side of the top of the guide block 703 is inclined in an arc shape.

[0029] This guides the wire rope 5 as it passes through the central through hole 702, reducing direct friction between the wire rope 5 and the side wall of the central through hole 702.

[0030] Example 3: The difference between this example and Example 1 is that the side of the mounting frame 704 is glued to the sponge board 705.

[0031] This makes the connection between the sponge board 705 and the mounting frame 704 more stable.

[0032] Example 4: The difference between this example and Example 1 is that a baffle is provided at the end of the connecting rod 707.

[0033] This makes the contact spring 708 more securely mounted on the contact connecting rod 707.

[0034] In this embodiment, because existing hydropower stations use winch-type gate hoists, the steel wire ropes used for hoisting are subjected to large tensions during actual operation and are often exposed to humid air and dust, causing water and dust to easily accumulate in the gaps between the rope strands, which can easily lead to internal rusting, reduce its strength and flexibility, greatly increase the risk of breakage, and pose a significant safety hazard.

[0035] In summary, in specific implementation, a winding protection component 7 is provided at the bottom of the support base 1. The limiting and fixing strip 701 in the winding protection component 7 is located at the bottom of the support base 1, and the bottom end of the wire rope 5 passes through the central through hole 702. Two guide blocks 703 are symmetrically arranged on the side wall at the top of the central through hole 702. The guide blocks 703 can guide the wire rope 5 passing through the central through hole 702, thereby avoiding excessive friction between the wire rope 5 and the side wall of the central through hole 702, which can easily cause damage. Two sponge plates 705 are symmetrically arranged inside the central through hole 702, and two oil tanks 709 are symmetrically arranged outside the limiting and fixing strip 701. Lubricating oil is added to the oil tanks 709 through the oil inlet 710, and the lubricating oil is transported to the side of the sponge plate 705 through the oil delivery pipe 712, thereby soaking into the sponge plate 705.

[0036] When the steel wire rope 5 passing through the central through hole 702 rubs against the side of the sponge plate 705, the lubricating oil impregnated in the sponge plate 705 lubricates the surface of the steel wire rope 5 during its winding and unwinding process. The side of the sponge plate 705 is fixedly connected by the mounting frame 704, and the side of the mounting frame 704 is elastically fixed by the contact connecting rod 707 and the contact spring 708 sleeved on it. This ensures that the sponge plate 705 always maintains contact with the side wall of the steel wire rope 5, resulting in better lubrication of the steel wire rope 5. This reduces friction during use and forms a protective film on the surface of the steel wire rope 5, preventing moisture and air from contacting it and providing rust prevention. This greatly reduces the risk of breakage and makes it safer and more reliable to use.
