Description

Technical Field

[0001] This invention belongs to the field of water conservancy equipment technology, and in particular relates to a water gate device for water conservancy projects. Background Technology

[0002] A sluice gate is a low-head hydraulic structure built on rivers and canals to control flow and regulate water levels using gates. Closing the gates can impound floodwaters, block tides, or raise upstream water levels to meet needs for irrigation, power generation, navigation, aquaculture, environmental protection, industrial, and domestic water use. Opening the gates can release floodwaters, waterlogged water, wastewater, or polluted water, and can also supply water to downstream rivers or canals. In water conservancy projects, sluice gates are widely used as structures for impounding, releasing, or drawing water.

[0003] Conventional sluice gates are mainly divided into two categories: those that rise upwards and those that open to the side. Among them, sluice gates that rise upwards are affected by the weight of the gate itself, which puts a relatively large load on the power unit. On the other hand, sluice gates that open to the side are affected by water pressure resistance, which also puts a relatively large load on the power unit. This results in a relatively large power load during the opening process of conventional sluice gates.

[0004] Therefore, we propose a sluice gate device for water conservancy projects to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to solve the problem of high power load during the opening process of conventional sluice gates, and to propose a sluice gate device for water conservancy projects.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A sluice gate device for a water conservancy project includes a dam. A motor and a restraint frame are fixedly connected to the upper part of the dam. A worm is fixedly connected to the rotor of the motor. A worm wheel meshes with the outside of the worm. The restraint frame is rolled and restrained outside the worm wheel and the worm. An arc-shaped valve plate is movably sealed at the rear of the dam. The upper end of the arc-shaped valve plate is fixedly connected to the worm wheel. A shaft column is provided on the rear side of the arc-shaped valve plate. The upper part of the shaft column is rotatably connected to the upper part of the arc-shaped valve plate. The system utilizes a motor to drive a worm gear, and a clamping frame firmly presses the worm wheel and worm gear together. This causes the worm gear to rotate, which in turn rotates the arc-shaped valve plate away from the motor. The arc-shaped valve plate then rotates backward along the inner wall of the dam, opening it and allowing water from the rear of the dam to drain forward through the opening. Similarly, the motor drives the worm gear in the opposite direction, which in turn rotates the worm wheel, causing the arc-shaped valve plate to re-close with the dam, sealing the opening. This system uses the arc-shaped valve plate's revolution to reduce the impact of water pressure on the valve plate, as well as its own weight, thus reducing the motor's operating load and improving practicality.

[0008] Preferably, a first bearing housing is rotatably mounted at the root of the worm. The first bearing housing increases the stability of the worm root.

[0009] Preferably, the dam includes a gatepost, a dam body, a sealing rod, and a connecting seat. The gatepost is fixedly connected to the inner end of the opening in the dam body, and the gatepost and the dam body are integrally cast structures. The sealing rod is fixedly installed at the lower part of the opening in the dam body. The inner arc surfaces of the gatepost and the sealing rod facilitate sealing of the front part of the arc-shaped valve plate.

[0010] Preferably, the dam further includes a reinforcing beam, which is fixedly connected between the two gateposts. The reinforcing beam increases the stability of the upper structure of the gateposts.

[0011] Preferably, the restraint frame includes a frame body, a first roller, and a second roller. A pair of first rollers are provided, and the first rollers are rotatably connected to the frame body. The second roller is rotatably installed inside the frame body. The second roller provides a force to the worm gear in the direction of the worm wheel, ensuring the worm gear is firmly engaged with the worm wheel, thus improving the stability of the worm and worm wheel transmission.

[0012] Preferably, the restraint frame further includes reinforcing blocks, which are distributed at the upper and lower ends of the frame and are fixedly connected to the frame as a whole. The reinforcing blocks increase the stability of the frame.

[0013] Preferably, the worm gear includes a guide ring, a first rotating frame, and a worm gear ring. The guide ring is distributed at the upper and lower ends of the worm gear ring, and the guide ring and the worm gear ring are an integral structure. The first rotating frame is fixedly connected to the inner end of the worm gear ring. The guide ring guides the first roller to roll, providing tension to the first roller. This tension is then applied to the second roller through the worm gear ring, facilitating the second roller to press against the outside of the worm.

[0014] Preferably, the arc-shaped valve plate includes an arc-shaped plate body and a second rotating frame, with the second rotating frame fixedly connected to the upper inner end of the arc-shaped plate body. When the worm gear rotates, it drives the worm wheel ring to rotate, which in turn drives the first rotating frame to rotate, which in turn drives the second rotating frame to rotate. This causes the second rotating frame to move the arc-shaped plate body, facilitating the control of the arc-shaped valve plate opening or closing.

[0015] Preferably, the upper part of the arc-shaped plate is uniformly perforated with drainage outlets. When the water level is too high, the water is discharged forward through the drainage outlets, thus playing a role in flood control.

[0016] Preferably, the shaft includes a second bearing seat and a flat column, with the lower end of the second bearing seat fixedly connected to the upper end of the flat column. The second bearing seat guides the rotation of the second rotating frame, the flat column stabilizes the axial position of the second rotating frame, and the flat structure of the flat column reduces the impact force of the water flow.

[0017] In summary, the technical effects and advantages of this invention are as follows:

[0018] 1. The motor drives the worm gear to rotate, and the clamping frame firmly presses the worm wheel and worm gear together, causing the worm gear to drive the worm wheel to rotate. The worm wheel then drives the arc-shaped valve plate to rotate away from the motor, causing the arc-shaped valve plate to rotate backward along the inner wall of the dam and open, allowing water on the back side of the dam to be discharged forward through the opening. Similarly, the motor drives the worm gear to rotate in the opposite direction, which in turn drives the worm wheel to rotate in the opposite direction, causing the worm wheel to drive the arc-shaped valve plate to close back onto the dam, sealing the dam opening. The rotation of the arc-shaped valve plate reduces the impact of water pressure on the arc-shaped valve plate, and also reduces the impact of the arc-shaped valve plate's own weight, reducing the operating load of the motor and improving practicality.

[0019] 2. The second roller provides a force to the worm gear in the direction of the worm wheel, making the worm gear firmly mesh with the worm wheel and improving the stability of the worm gear and worm wheel transmission.

[0020] 3. The guide ring guides the first roller to roll, providing tension to the first roller. The worm gear ring acts on the second roller, making it easier for the second roller to press against the outside of the worm.

[0021] 4. When the worm rotates, it drives the worm wheel ring to rotate, which in turn drives the first rotating frame to rotate. The first rotating frame then drives the second rotating frame to rotate, which in turn drives the arc-shaped plate, making it easier to control the opening or closing of the arc-shaped valve plate.

[0029] The technical solutions in the embodiments of the invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the invention, and not all embodiments.

[0030] Reference Figure 1 A water gate device for a water conservancy project includes a dam 2. A motor 1 and a restraint frame 3 are fixedly connected to the upper part of the dam 2. A worm 8 is fixedly connected to the rotor of the motor 1. A worm wheel 4 meshes with the outside of the worm 8. The restraint frame 3 is rolled and restrained to the outside of the worm wheel 4 and the worm 8. An arc-shaped valve plate 5 is movably sealed at the rear of the dam 2. The upper end of the arc-shaped valve plate 5 is fixedly connected to the worm wheel 4. A shaft column 6 is provided on the rear side of the arc-shaped valve plate 5. The lower end of the shaft column 6 is fixed through the riverbed. The upper part of the shaft column 6 is rotatably connected to the upper part of the arc-shaped valve plate 5. The motor 1 drives the worm gear 8 to rotate, and the clamping frame 3 firmly presses the worm wheel 4 and the worm gear 8 together, causing the worm gear 8 to drive the worm wheel 4 to rotate. The worm wheel 4 then drives the arc-shaped valve plate 5 to rotate away from the motor 1 in the opposite direction, causing the arc-shaped valve plate 5 to rotate backward along the inner wall of the dam 2 and open, allowing the water on the back side of the dam 2 to be discharged forward through the opening of the dam 2. Similarly, the motor 1 is driven in the opposite direction to drive the worm gear 8 to rotate in the opposite direction, which in turn drives the worm wheel 4 to rotate in the opposite direction, causing the worm wheel 4 to drive the arc-shaped valve plate 5 to close back with the dam 2, sealing the opening of the dam 2. The rotation of the arc-shaped valve plate 5 reduces the impact of water pressure on the arc-shaped valve plate 5, and also reduces the impact of the arc-shaped valve plate 5's own weight.

[0031] Reference Figure 1 A first bearing housing 7 is rotatably mounted at the root of the worm 8. The first bearing housing 7 is used to increase the stability of the root of the worm 8.

[0032] Reference Figure 1 and 2 The dam 2 includes a gatepost 21, a dam body 22, a sealing rod 24, and a connecting seat 25. A motor 1 is fixedly connected between the gatepost 21 and the dam body 22. A first bearing seat 7 is fixedly connected to the gatepost 21, which is fixedly connected to the inner end of the opening in the dam body 22. The gatepost 21 and the dam body 22 are integrally cast structures. The sealing rod 24 is fixedly installed at the lower part of the opening in the dam body 22. The inner arc surfaces of the gatepost 21 and the sealing rod 24 are used to seal the arc-shaped valve plate 5.

[0033] Reference Figure 1 and 2 The dam 2 also includes a reinforcing beam 23, which is fixedly connected between the two gateposts 21. The reinforcing beam 23 is used to increase the stability of the upper structure of the gateposts 21.

[0034] Reference Figure 1 and 3 The restraint frame 3 includes a frame body 32, a first roller 33, and a second roller 34. The second roller 34 rolls and presses against the outer end of the worm 8. The worm 8 passes through the inner side of the frame body 32 without contacting it. A pair of first rollers 33 are provided, and the first rollers 33 are rotatably connected to the frame body 32. The second rollers 34 are rotatably installed inside the frame body 32. The second rollers 34 provide a force to the worm 8 in the direction of the worm wheel 4, so that the worm 8 is firmly engaged with the worm wheel 4.

[0035] Reference Figure 1 , 2 The restraint frame 3 also includes reinforcing blocks 31. The lower reinforcing blocks 31 and the frame body 32 are both fixedly connected to the connecting seat 25. The reinforcing blocks 31 are distributed at the upper and lower ends of the frame body 32, and the reinforcing blocks 31 are fixedly connected to the frame body 32 as a whole. The reinforcing blocks 31 are used to increase the stability of the frame body 32.

[0036] Reference Figure 1 , 3 The worm gear 4 includes a guide ring 41, a first rotating frame 42, and a worm gear ring 43. The worm gear ring 43 meshes with the worm 8. The first roller 33 rolls and presses against the inner end of the guide ring 41. The guide ring 41 is distributed at the upper and lower ends of the worm gear ring 43, and the guide ring 41 and the worm gear ring 43 are an integral structure. The first rotating frame 42 is fixedly connected to the inner end of the worm gear ring 43. The guide ring 41 guides the first roller 33 to roll, providing tension to the first roller 33. Through the worm gear ring 43, the force acts on the second roller 34, causing the second roller 34 to press against the outside of the worm 8.

[0037] Reference Figure 1 , 4 5. The arc-shaped valve plate 5 includes an arc-shaped plate body 51 and a second rotating frame 52. The second rotating frame 52 is rotatably connected to the shaft column 6. The upper end of the second rotating frame 52 is fixedly connected to the inner end of the first rotating frame 42. The upper end of the arc-shaped plate body 51 is fixedly connected to the lower guide ring 41. The second rotating frame 52 is fixedly connected to the upper inner end of the arc-shaped plate body 51. When the worm gear 8 rotates, it drives the worm wheel ring 43 to rotate, which in turn drives the first rotating frame 42 to rotate. The first rotating frame 42 then drives the second rotating frame 52 to rotate, causing the second rotating frame 52 to drive the arc-shaped plate body 51.

[0038] Reference Figure 5The upper part of the arc-shaped plate 51 is evenly perforated with drainage outlets 53. When the water level is too high, it is discharged forward through the drainage outlets 53.

[0039] Reference Figure 1 , 5 The shaft column 6 includes a second bearing seat 61 and a flat column 62. The flat column 62 is fixed to the riverbed. The lower part of the second rotating frame 52 is rotatably connected to the second bearing seat 61, and the lower end of the second bearing seat 61 is fixedly connected to the upper end of the flat column 62. The second bearing seat 61 guides the rotation of the second rotating frame 52, the flat column 62 stabilizes the axial position of the second rotating frame 52, and the flat structure of the flat column 62 reduces the impact force of the water flow.

[0040] Working principle: Motor 1 drives worm 8 to rotate. The clamping frame 3 firmly presses worm wheel 4 and worm 8 together, causing worm 8 to drive worm wheel 4 to rotate. Worm wheel 4 then drives arc-shaped valve plate 5 to rotate away from motor 1, causing arc-shaped valve plate 5 to rotate backward along the inner wall of dam 2 and open, allowing water on the rear side of dam 2 to drain forward through the opening. Similarly, the reverse drive motor 1 drives worm 8 to rotate in the opposite direction, which in turn drives worm wheel 4 to rotate in the opposite direction, causing worm wheel 4 to drive arc-shaped valve plate 5 to close again with dam 2, sealing it. The opening of the dam 2 utilizes the revolution of the arc-shaped valve plate 5 to reduce the impact of water pressure on the arc-shaped valve plate 5, and also reduces the impact of the arc-shaped valve plate 5's own weight; the second roller 34 provides a force to the worm 8 in the direction of the worm wheel 4, so that the worm 8 is firmly engaged with the worm wheel 4; when the worm 8 rotates, it drives the worm wheel ring 43 to rotate, which in turn drives the first rotating frame 42 to rotate, which in turn drives the second rotating frame 52 to rotate, which in turn drives the arc-shaped plate 51.
