Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a hoist-type upward-flipping gate. Background Technology

[0002] A sluice gate is a hydraulic engineering facility primarily used to regulate water flow. It controls water level and flow by opening and closing gates, and is typically built on waterways such as rivers and canals. Sluice gates differ from pumping stations. Sluice gates control water level and flow by opening and closing gates, primarily for water level regulation, flood control, and hydropower utilization; while pumping stations raise water levels or transport water to designated locations by pumping water, primarily for water allocation and supply.

[0003] In addition, sluice gates are usually built on waterways where water flows naturally and no additional energy input is required, so their operating costs are relatively low; while pumping stations require energy to operate, so their operating costs are relatively high.

[0004] The working principle of a sluice gate: A sluice gate controls water level and flow by opening and closing gates. Closing the gates can block floods and tides, while opening the gates can release floodwaters, drain waterlogged areas, and divert water. The water body has a certain water level difference before and after the gate, allowing for natural flow without the need for additional power.

[0005] Generally, gates are opened and closed by moving them vertically. Therefore, gates are always in a vertical position and are quite tall. When performing maintenance on them while standing on the gate pier, the gate is often too low or too high above the top of the pier, making maintenance quite troublesome. Utility Model Content

[0006] The purpose of this utility model is to provide a hoist-type upward-opening gate, which has the advantage of facilitating gate maintenance.

[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0008] A winch-type upward-opening gate includes a gate pier, a platform base plate fixedly connected to the top of the gate pier, a gate between the two side walls of the gate pier, and the gate being rotatably connected to the two side walls of the gate pier on its top sides respectively. A lifting lug is fixedly connected to one side of the gate. A winch and a pulley seat are fixedly connected to the upper part of the platform base plate. A fixed pulley is rotatably connected to the pulley seat. The end of the winch wire rope passes around the fixed pulley and is tied to the lifting lug of the gate. Locking devices are respectively provided on the two side walls of the gate near its top. When the gate is connected to the locking device, the gate is in a horizontal state.

[0009] Using the above technical solution, when the gate is being inspected, the winch winds up the wire rope, which pulls the gate to rotate. The gate approaches the top surface of the gate pier. When the gate rotates to a horizontal position, a locking device is used to fix it, keeping the gate in this position. Then, the gate can be inspected from above the top of the gate pier. When the gate is horizontal, its side surface faces upward, so all parts of the gate that need to be inspected are at the same horizontal height. When the gate is pulled up and placed flat on the top of the gate pier, maintenance can be carried out. All parts of the gate are on the top of the gate pier, making disassembly and maintenance more convenient, thereby improving the efficiency of maintenance. At the same time, the gate is more stable in a horizontal position, and it will not shake during maintenance and disassembly.

[0010] Preferably, a stop block is fixedly connected to the bottom of the gate pier, the stop block is located on the downstream side of the gate, and the stop block is located diagonally below the connection between the gate and the gate pier.

[0011] With the above technical solution, when the gate is closed, the lower end of the gate rests against the stop block, so that the gate is in a vertical position. The stop block is used to share the tension of the gate on the winch, reduce the load on the winch wire rope, and at the same time make the gate close more stably.

[0012] Preferably, two opposing gate slots are provided on both sides of the front and rear ends of the gate, and a trash rack passes through the two opposing gate slots at each end of the gate, with the gate located between the two trash racks.

[0013] By adopting the above technical solution, debris in the water is blocked, preventing it from flowing into the water on the other side of the sluice gate and affecting the environment.

[0014] Preferably, a maintenance bridge is provided between two adjacent gate piers and between the two side walls of the gate piers.

[0015] The above technical solution facilitates movement between various gate piers, thereby enabling the maintenance of multiple gates.

[0016] Preferably, the lifting lug is located near the bottom of the gate.

[0017] By adopting the above technical solution, the distance between the connection between the wire rope and the gate and the connection between the gate and the gate pier is increased, thereby reducing the force required by the winch to make the gate rotate.

[0018] Preferably, the locking device includes two support plates, each with a horizontal slot. A vertical screw is threaded onto the upper side wall of the slot. The support plates are fixedly connected to a rotating shaft. The rotating shafts of the two support plates are vertically rotatably connected to both sides of the gate pier near its top. A rotating handle is fixedly connected to one end of the rotating shaft of each support plate located on the upper part of the top surface of the gate pier.

[0019] Using the above technical solution, the winch drives the gate to rotate to a horizontal position, and then the handles of the top support plates on both sides of the gate pier are rotated respectively, causing the two support plates to rotate, so that the slots of the two support plates are respectively engaged with the left and right sides of the gate. The winch unloads the force, and the lower side of the slots of the support plates supports the gate. Then the screw is turned to make it press against the gate, thereby fixing the gate in a horizontal position. Attached Figure Description

[0026] The following description is merely a preferred embodiment of this utility model, and the scope of protection is not limited to this embodiment. All technical solutions falling within the scope of this utility model should be considered within the protection scope of this utility model. It should also be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.

[0027] See Figures 1 to 5A winch-type upward-tilting gate includes multiple gate piers 1, which stand in the river channel. Maintenance bridges 8 are installed between adjacent gate piers 1 and between the side walls of each gate pier 1, facilitating movement between the gate piers 1 for maintenance of the multiple gates 2. A platform base plate is fixedly connected to the top of each gate pier 1. A gate 2 is installed between the side walls of each gate pier 1, and the gate 2 is rotatably connected to embedded parts cast in the sides of the gate pier 1 via fixed rotating shafts on its top sides. The connection between the gate 2 and the gate pier 1 is located on the inner river side. A lifting lug 3 is fixedly connected to one side of the gate 2 near its bottom end, located on the outer river side. The lifting lug 3 increases the distance between the point where the steel wire rope exerts tension on the gate 2 and the connection between the gate 2 and the gate pier 1, thereby reducing the force required for the winch 4 to rotate the gate 2. A winch 4 and a pulley seat are fixedly connected to the upper part of the platform base plate. The winch 4 is a QH double-lifting-point winch 4. The winch 4 and the pulley seat are located on the inner and outer river sides, respectively. The pulley seat is connected to a fixed pulley 5. The end of the wire rope of the winch 4 passes around the fixed pulley 5 and is tied to the lifting lug 3 of the gate 2. Locking devices are respectively installed on the two side walls of the gate 2 near its top. When the gate 2 is connected to the locking device, the gate 2 is in a horizontal state. The locking device includes two support plates 9. The support plates 9 have horizontal slots. The upper side wall of the slots is threaded with a vertical screw 10. The support plates 9 are fixedly connected to a rotating shaft. The rotating shafts of the two support plates 9 are vertically rotatably connected to the two sides of the gate pier 1 near its top through embedded parts cast in the gate pier 1. A rotating handle 11 is fixedly connected to one end of the rotating shaft of each support plate 9 located on the upper part of the top surface of the gate pier 1. Two opposing gate slots are provided on both sides of the front and rear ends of the gate 2. A debris barrier 7 passes through each of the two opposing gate slots at each end of the gate 2. The gate 2 is located between the two debris barriers 7, blocking debris in the water and preventing it from flowing into the water on the other side of the gate 2 and affecting the environment. A stop block 6 is fixedly connected to the bottom of the gate pier 1 on the outer river side. The stop block 6 is located diagonally below the connection between the gate 2 and the gate pier 1. When the gate 2 is closed, the lower end of the gate 2 rests against the stop block 6, keeping the gate 2 in a vertical position. The stop block 6 is used to share the tension of the gate 2 on the winch 4, reducing the load on the winch 4's wire rope, and also making the closure of the gate 2 more stable.

[0028] Working principle: When the gate 2 is being inspected, the winch 4 winds up the wire rope, which pulls the gate 2 to rotate. The gate 2 moves closer to the top surface of the gate pier 1. When the gate 2 is rotated to a horizontal position, the handles 11 of the support plates 9 on both sides of the gate pier 1 are rotated to rotate the two support plates 9. The slots of the two support plates 9 are then engaged with the left and right sides of the gate 2. The winch 4 releases its force, and the lower side of the slots of the support plates 9 supports the gate 2. Then the screw 10 is turned to press against the gate 2, thus fixing the gate 2 in a horizontal position. Then the gate 2 can be inspected from above the top of the gate pier 1. When the gate 2 is in a horizontal position, its side surface faces upwards. Therefore, all parts of the gate 2 that need to be inspected are at the same horizontal level. When the gate 2 is pulled up and placed flat on the gate pier 1, maintenance can be carried out. All components of the gate 2 are on the gate pier 1, making disassembly and maintenance more convenient and thus improving the efficiency of maintenance. At the same time, the gate 2 is more stable in a horizontal position, and it will not shake during maintenance and disassembly.
