Abstract
Description
Technical Field
[0001] The utility model relates to the field of water conservancy projects, in particular to a hoist for water conservancy projects. Background Art
[0002] The hoist of a water conservancy project is a mechanical device used to control water conservancy project facilities such as sluice gates, ship locks, and dam gates. It can be manual, electric, hydraulic, or pneumatic, and is used to open and close the gate to regulate the water level, control the water flow, or allow ships to pass. Since the hoist for controlling the lifting gate valve has a long stroke and a long opening and closing time, and the rotating gate plate requires a large external force for opening and closing, there is a high demand for the power of the hoist. Summary of the Utility Model
[0003] The purpose of the utility model is to provide a hoist for water conservancy projects to solve the problems raised in the above background art.
[0004] To achieve the above purpose, the utility model provides the following technical solutions:
[0005] A hoist for water conservancy projects includes a fixed bottom plate, a valve plate fixing frame, a rotating shaft, a rotating valve plate, a reinforcing rib, a fixed pull ring, a fixed ear, a traction rope, a reserved hole, a wire winding roller, a motor, and a side fixed column. Valve plate fixing frames are installed at the top of both sides of the fixed bottom plate. Rotating valve plates are installed on both the left and right sides inside the valve plate fixing frame through rotating shafts. Two reinforcing ribs are installed on the front end of each rotating valve plate. A fixed pull ring is welded in the center of the two reinforcing ribs on the rotating valve plate. Fixed ears are welded and installed at the center, left and right sides, and top of the front end of the valve plate fixing frame. A wire winding roller is installed inside the center of the top of the valve plate fixing frame, and reserved holes leading to the wire winding roller are opened on both sides at the top of the front end of the valve plate fixing frame. Traction ropes are installed on both fixed pull rings, and after passing through the two fixed ears on the same side in sequence, the traction ropes pass through the corresponding reserved holes and are connected to the wire winding roller. A motor is installed at the center of the top of the valve plate fixing frame through a side fixed column, and the motor is connected to the wire winding roller below.
[0006] Preferably, the inner angle is 120° when the left and right rotating valve plates are closed, and the two rotating valve plates on both sides are tightly closed by water pressure.
[0007] The beneficial effect of the utility model is that the utility model is reasonably designed. The valve plate is opened through the traction rope, and the structure is simple and reliable. When closing the valve plate, the water flow can be used to push the valve plate to close, and a high water pressure is always maintained to tightly close the two valve plates on both sides, maintaining good airtightness without additional power. Brief Description of the Drawings
[0008] Figure 1 It is a schematic structural diagram of the hoist for water conservancy projects of the utility model.
[0009] In the figure: 1. Fixed bottom plate, 2. Valve plate fixing frame, 3. Rotating shaft, 4. Rotating valve plate, 5. Reinforcing rib, 6. Fixed pull ring, 7. Fixed lug, 8. Traction rope, 9. Reserved hole, 10. Wire winding roller, 11. Motor, 12. Side fixed column. Specific embodiments
[0010] The present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments:
[0011] As Figure 1 shown, a hoist for water conservancy projects includes a fixed bottom plate 1, a valve plate fixing frame 2, a rotating shaft 3, a rotating valve plate 4, a reinforcing rib 5, a fixed pull ring 6, a fixed lug 7, a traction rope 8, a reserved hole 9, a wire winding roller 10, a motor 11, and a side fixed column 12. Valve plate fixing frames 2 are installed at the top of both sides of the fixed bottom plate 1. Rotating valve plates 4 are installed on the left and right sides inside the valve plate fixing frames 2 through rotating shafts 3. Two reinforcing ribs 5 are installed on the front ends of the rotating valve plates 4. A fixed pull ring 6 is welded in the center of the two reinforcing ribs 5 on the rotating valve plates 4. Fixed lugs 7 are welded and installed at the center, left and right sides, and top of the front end of the valve plate fixing frame 2. A wire winding roller 10 is installed inside the center of the top of the valve plate fixing frame 2, and reserved holes 9 leading to the wire winding roller 10 are opened on both sides of the top of the front end of the valve plate fixing frame 2. Traction ropes 8 are installed on both fixed pull rings 6, and after passing through the two fixed lugs 7 on the same side in sequence, the traction ropes 8 pass through the corresponding reserved holes 9 and are connected to the wire winding roller 10. A motor 11 is installed at the center of the top of the valve plate fixing frame 2 through a side fixed column 12, and the motor 11 is connected to the wire winding roller 10 below. The inner angle is 120° when the left and right rotating valve plates 4 are closed, and the two rotating valve plates 4 on both sides are tightly closed by water pressure.
[0012] The working principle of the present utility model: The motor 11 drives the wire winding roller 10 to rotate, recovering the traction ropes 8 on both sides. The traction ropes 8 drive the fixed pull ring 6 to pull the rotating valve plates 4 to both sides. When it is necessary to close, only the motor 11 controls the wire winding roller 10 to release the traction ropes 8. The two rotating valve plates 4 on both sides are closed by the impact of water flow, and after closing, the two rotating valve plates 4 on both sides are tightly closed by water pressure.
