Description

Technical Field

[0001] The invention relates to the technical field of antifreezing of hydraulic gates, and in particular to an antifreezing device for a water-facing surface of a hydraulic gate. Background Art

[0002] Hydraulic gates are important equipment for controlling water flow in water conservancy projects and are widely used in reservoirs, rivers, canals, drainage systems, ports, locks and other places. Hydraulic gates control the flow, direction and water level of water by opening, closing or adjusting the opening, thereby achieving the purposes of flood control, irrigation, water supply, power generation, shipping, etc. In cold areas, the water-facing surface of hydraulic gates is prone to ice in winter, which will not only affect the normal opening and closing of the gates, but may also cause damage to the gate structure. Therefore, anti-freeze measures are crucial to ensure the safe operation of water conservancy projects.

[0003] There are still some problems in the use of the existing anti-freezing device for the water-facing surface of the hydraulic gate. The current anti-freezing measures for the water surface generally use a motor to drive a stirring rod to stir the water-facing surface of the gate, thereby accelerating the water flow speed on the water-facing surface, thereby preventing the water surface from freezing. However, the continuous use of the motor for stirring consumes a lot of electric energy. Therefore, the technical personnel in this field provide a water-facing surface anti-freezing device for the hydraulic gate to solve the problems raised in the above background technology.

[0013] (III) Beneficial effects

[0014] The present invention provides an anti-freezing device for the water-facing surface of a hydraulic gate. It has the following beneficial effects:

[0015] 1. In the present invention, water from the upstream enters the downstream of the gate body through the underwater guide pipe, and impacts the two turbines, thereby driving the connecting rod to rotate, and the connecting rod drives the generator to rotate, thereby generating electric energy. The generated electric energy is rectified and stabilized by the rectifier and voltage stabilizer and then transmitted to the inside of the first storage battery. When the connecting rod rotates, it drives the N pole of the magnetic coupler to rotate, and the N pole of the magnetic coupler drives the S pole of the magnetic coupler to rotate, and the S pole of the magnetic coupler drives the first synchronous wheel to rotate, and the second synchronous wheel drives the connecting seat to rotate through the four limit blocks on the outer wall of the rotating rod sliding on the inner side of the four card slots.

[0016] 2. In the present invention, when the upper surface of the water on the water-facing surface is frozen and the stirring blade cannot rotate, the setting of the N pole and the S pole of the magnetic coupler will not affect the rotation of the connecting rod. The control box then controls the second battery to supply power to the heating wire through the conductive slip ring. The heat generated by the heating wire after being energized defrosts the water surface on the water-facing surface.

[0017] 3. In the present invention, the buoyancy of the two storage boxes is increased by two buoyancy blocks, so that the two storage boxes are always on the water surface and can be adaptively adjusted according to the height of the water surface. When the water surface height changes, the two storage boxes rise or fall with the water surface. Since the connecting seat and the rotating rod are rotated through four slots and four limit blocks, and the four limit blocks are relatively long, they can adapt to the rise and fall of the rotating rod. The length of the second gear is greater than the first gear, which can also adapt to the rise and fall of the rotating rod. The storage box on the other side is guided up and down through the sliding connection between the lifting rod and the second support plate, so that the two first storage boxes will not shake and can only move up and down, which is convenient for adaptive water surface height.

[0018] 4. In the present invention, when the water flows slowly and cannot provide power for the rotating rod, the servo motor can be started by controlling the control box, the servo motor drives the second gear to rotate, the second gear drives the first gear to rotate, and the first gear drives the rotating rod to rotate, thereby actively driving the rotating rod to rotate for stirring, thereby improving the flexibility of equipment use.

When water flows through the guide pipe 8, it impacts the two turbines 13, so that the two turbines 13 are A turbine 13 drives the connecting rod 9 to rotate, and the upper end of the connecting rod 9 sequentially penetrates the upper inner wall of the guide tube 8 and the lower end surface of the first support plate 2 to the upper end surface of the first support plate 2, and the end is fixedly connected with a generator 4.

[0029] The driving structure 3 includes a magnetic coupler N pole 309, which is fixedly sleeved on the outer wall of the connecting rod 9 at the lower end of the first support plate 2. The outer wall of the magnetic coupler N pole 309 is sleeved with a magnetic coupler S pole 310, and the outer wall of the magnetic coupler S pole 310 is fixedly sleeved with a first synchronous wheel 311. A bearing 323 is fixedly connected to the front center of the lower end surface of the first support plate 2. The outer ring of the bearing 323 passes through the lower end surface of the first support plate 2 and passes to the upper end surface of the first support plate 2, and is fixedly connected to the first support plate 2. A second synchronous wheel 314 is fixedly connected to the lower end surface of the inner ring of the bearing 323. A synchronous belt 312 is sleeved on the outer wall of the second synchronous wheel 314 and the outer wall of the first synchronous wheel 311. A connecting seat 313 is fixedly connected to the inner ring of the bearing 323. The inner side of the connecting seat 313 Four card slots 324 are arranged in a rectangular shape on the wall, a rotating rod 304 is arranged inside the connecting seat 313, four limit blocks 315 are arranged in a rectangular shape at the upper part of the outer wall of the rotating rod 304, a first umbrella wheel 317 is fixedly connected to the lower end of the rotating rod 304, storage boxes 301 are provided on the outer side of the first umbrella wheel 317 and on one side of the first umbrella wheel 317, four support rods 316 are fixedly connected in a rectangular shape between the two storage boxes 301, a second third wheel 318 is meshed and connected at the lower part of one side of the first umbrella wheel 317, a shaft rod 319 is fixedly connected at the center of one side wall of the second third wheel 318, one end of the shaft rod 319 passes through the inner wall of one storage box 301 and the one side wall of the other storage box 301 in sequence to the inside of the other storage box 301, and a stirring blade 302 is provided on the outer wall of the shaft rod 319 between the two storage boxes 301.

[0030] When the connecting rod 9 rotates, it drives the N pole 309 of the magnetic coupler to rotate, and the N pole 309 of the magnetic coupler drives the S pole 310 of the magnetic coupler to rotate, and the S pole 310 of the magnetic coupler drives the first synchronous wheel 311 to rotate, and drives the second synchronous wheel 314 to rotate through the synchronous belt 312, and the second synchronous wheel 314 drives the connecting seat 313 to rotate, and the four limit blocks 315 on the outer wall of the rotating rod 304 slide on the inner side of the four slots 324, and the second synchronous wheel 314 is driven to rotate while the connecting seat 313 rotates, thereby driving the first umbrella wheel 317 to rotate, the first umbrella wheel 317 drives the second third wheel 318 to rotate, and the second third wheel 318 drives the shaft rod 319 to rotate, so that the stirring blade 302 rotates, stirs the surface water on the water-facing surface of the gate body 6, increases the surface fluidity, prevents freezing, and does not need to use additional electricity for power supply, thereby reducing the loss of electricity.

[0031] A conductive slip ring 321 is fixedly connected to the end of the shaft rod 319 inside the storage box 301 on the other side wall. A second battery 322 is provided inside the storage box 301 on one side of the conductive slip ring 321. A heating wire 320 is provided inside the shaft rod 319. The heating wire 320 is electrically connected to the conductive slip ring 321. The heating wire 320 is connected via the conductive slip ring 321 to continuously energize the heating wire 320 during the rotation of the shaft rod 319. When the water on the facing surface has frozen, the second battery 322 can energize and heat the heating wire 320 via the conductive slip ring 321 to thaw the water surface and then continue to stir.

[0032] A first gear 305 is fixedly connected to the upper end surface of the rotating rod 304, and a servo motor 306 is provided at one side of the center of the upper end surface of the gate body 6. A second gear 307 is fixedly connected to the output end of the servo motor 306. The second gear 307 is meshingly connected to the first gear 305. The length of the second gear 307 is greater than the first gear 305. By controlling the servo motor 306 to start, the servo motor 306 drives the second gear 307 to rotate, and then drives the first gear 305 to rotate through the second gear 307, thereby driving the rotating rod 304 to rotate, thereby realizing active stirring of the water surface.

[0033] The upper part of the outer wall of the two storage boxes 301 is fixedly connected with a buoyancy block 303. The two buoyancy blocks 303 increase the buoyancy of the two storage boxes 301, so that the two storage boxes 301 are always on the water surface and can be adaptively adjusted according to the height of the water surface.

[0034] A lifting rod 308 is fixedly connected to the center of the upper end surface of the storage box 301 on the other side. The lifting rod 308 passes through the lower end surface of the second support plate 7 and reaches the upper end of the second support plate 7. The lifting rod 308 is slidably connected to the second support plate 7. After being guided by the lifting rod 308, the height of the two storage boxes 301 and the stirring blades 302 can be adjusted according to the height of the water surface in coordination with the up and down movement of the rotating rod 304.

[0035] Working principle: When in use, the gate body 6 is closed, and the water from the upstream enters the downstream of the gate body 6 through the underwater guide pipe 8, and impacts the two turbines 13, thereby driving the connecting rod 9 to rotate, and the connecting rod 9 then drives the generator 4 to rotate, thereby generating electric energy. The generated electric energy is rectified and stabilized by the rectifier and voltage regulator 12 and then transmitted to the inside of the first storage battery 11. When the connecting rod 9 rotates, it drives the N pole 309 of the magnetic coupler to rotate, and the N pole 309 of the magnetic coupler then drives the S pole 310 of the magnetic coupler to rotate, and the S pole 310 of the magnetic coupler then drives the first synchronous wheel 311 to rotate, and drives the second synchronous wheel 312 through the synchronous belt 312. The wheel 314 rotates, and the second synchronous wheel 314 drives the connecting seat 313 to rotate. The four limit blocks 315 on the outer wall of the rotating rod 304 slide on the inner sides of the four slots 324. When the connecting seat 313 rotates, the second synchronous wheel 314 is driven to rotate, thereby driving the first umbrella wheel 317 to rotate, the first umbrella wheel 317 drives the second third wheel 318 to rotate, and the second third wheel 318 drives the shaft rod 319 to rotate, so that the stirring blade 302 rotates, and the surface water on the water-facing surface of the gate body 6 is stirred to increase the surface fluidity and prevent freezing. No additional electric energy is needed for power supply, thereby reducing the loss of electric energy.

[0036] When the upper surface of the water on the water-facing surface freezes and the stirring blade 302 cannot rotate, the setting of the magnetic coupler N pole 309 and the magnetic coupler S pole 310 will not affect the rotation of the connecting rod 9. The control box 10 then controls the second battery 322 to supply power to the heating wire 320 through the conductive slip ring 321. The heat generated by the heating wire 320 after being energized defrosts the water surface. When the thawing is about to end, or when the water flows slowly and the connecting rod 9 cannot provide power for the rotating rod 304, the control box 10 can be used to control the servo motor 306 to start, and the servo motor 306 drives the second gear 307 to rotate, and the second gear 307 drives the first gear 305 to rotate, and the first gear 305 drives the rotating rod 304 to rotate, thereby actively driving the rotating rod 304 to rotate for stirring.

[0037] The buoyancy of the two storage boxes 301 is increased by two buoyancy blocks 303, so that the two storage boxes 301 are always on the water surface, and can be adaptively adjusted according to the height of the water surface. When the water surface height changes, the two storage boxes 301 rise or fall with the water surface. Since the connecting seat 313 and the rotating rod 304 are rotated through four card slots 324 and four limit blocks 315, and the four limit blocks 315 are relatively long, they can adapt to the rise and fall of the rotating rod 304, and the length of the second gear 307 is greater than the first gear 305, which can also adapt to the rise and fall of the rotating rod 304. Then, the sliding connection between the lifting rod 308 and the second support plate 7 is used to guide the storage box 301 on the other side up and down, so that the two first storage boxes 301 will not shake and can only move up and down, which is convenient for adaptive water surface height.

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
