Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy equipment, in particular to an anti-deformation hydraulic gate. Background Art

[0002] A sluice is a hydraulic structure built on a river or canal that uses a gate to control flow and adjust water levels. Closing the gate can block floods, tides, or raise the upstream water level to meet the needs of irrigation, power generation, shipping, aquaculture, environmental protection, industry, and domestic water. Opening the gate can discharge floods, waterlogging, abandoned water, or wastewater, and can also supply water to the downstream river or canal. In water conservancy projects, sluices are widely used as structures for retaining, discharging, or taking in water.

[0003] Publication number "CN211421056U" provides a hydraulic gate, which is provided with an anti-collision body, which is detachably connected to the gate, and a transmission structure includes a motor, a small gear connected to the motor shaft, a large gear meshing with the small gear, and a shaft mounted on a support frame and fixedly connected to the large gear, which can effectively resist stone impact.

[0004] However, the above technical solutions and the prior art have the following defects:

[0005] Firstly, the transmission structure of the hydraulic gate needs to control the synchronous rotation of two sets of motors in actual use to make the gate open and close. However, this transmission structure is not only complex in structure, but also when the motor does not have the self-locking ability, the gate is prone to fall back after opening. Secondly, the anti-collision body of the gate has a low protection range and can only provide anti-collision protection for the lower half of the front end surface of the gate, but not for the upper half of the front end surface of the gate, so it is not practical.

[0027] Embodiment 1:

The fixing plate 1 is fixedly connected to the side of the gate frame 2, and the fixing plate 1 is convenient for installing and fixing the gate frame 2. The gate body 5 is installed inside the gate frame 2. Since the internal detailed structure and working principle of the gate body 5 are relatively mature technologies in the prior art, they will not be described in detail here. The limiting grooves 4 are symmetrically arranged on the left and right sides of the inner wall of the gate frame 2, and the limiting grooves 4 are matched with the gate body 5. The limiting grooves 4 will limit and guide the gate body 5 to prevent the gate body 5 from shaking or deflecting during the lifting and use process.

[0029] A lifting assembly 3 for opening and closing the gate body 5 is arranged in the middle position of the upper end surface of the gate frame 2, and a reinforcing assembly 6 is arranged on the front end surface of the gate body 5, and the reinforcing assembly 6 is used to increase the strength of the front end surface of the gate body 5 to prevent the front end surface of the gate body 5 from being easily deformed when it is hit by stones or impacted by water flow.

[0030] The lifting assembly 3 includes a driving motor 31, a protective cover 32, a lifting screw 33, a rotating worm 35, a transmission worm wheel 36 and a rotating sleeve 37. A protective cover 32 is installed at the middle position of the upper end surface of the gate frame 2. The protective cover 32 will support and protect the rotating worm 35, the driving motor 31 and the follower ring 38. The right end surface of the protective cover 32 is installed with a driving motor 31. The driving motor 31 is a torque motor. The driving motor 31 is connected to the external control panel through a wire. The driving motor 31, which is a torque motor, will drive the rotating worm 35 to rotate. A rotating worm 35 is installed at the left end of the driving motor 31. When the rotating worm 35 rotates, it will drive the transmission worm wheel 36 to rotate.

[0031] A transmission worm wheel 36 is meshed with the front side of the annular side surface of the rotating worm 35, and the transmission worm wheel 36 will drive the rotating sleeve 37 to rotate. A rotating sleeve 37 is arranged inside the transmission worm wheel 36. The rotating sleeve 37 is connected to the transmission worm wheel 36 and the follower ring 38 by welding. When the rotating sleeve 37 rotates, it will drive the lifting screw rod 33 to move up and down. A lifting screw rod 33 is arranged inside the rotating sleeve 37. The lifting screw rod 33 is connected to the gate body 5 through a connecting seat 34. The lifting screw rod 33 will drive the gate body 5 to lift and open and close through the connecting seat 34. A follower ring 38 is arranged at the bottom of the rotating sleeve 37, and an annular blocking cover 321 is installed on the lower side of the inner wall of the protective cover 32. The follower ring 38 and the annular blocking cover 321 prevent the rotating sleeve 37 from being displaced up and down or shaking during the rotation and use. An internal thread is arranged on the inner annular side surface of the rotating sleeve 37, and the internal thread is meshed with the lifting screw rod 33. The internal thread enables the rotating sleeve 37 to drive the lifting screw rod 33 to move up and down when rotating forward and reverse.

[0032] Embodiment 2:

[0033] On the basis of the first embodiment, in this embodiment, a reinforcement plate 63 is installed on the front end face of the gate body 5, so that the strength of the front end face of the gate body 5 can be improved, and the multiple vertical reinforcement plates 62 and transverse reinforcement plates 61 fixedly connected can further improve the strength of the reinforcement plate 63, thereby preventing the gate body 5 from being easily deformed during use.

[0034] The reinforcement assembly 6 includes a transverse reinforcement plate 61, a vertical reinforcement plate 62 and a reinforcement plate 63. The front end face of the gate body 5 is installed with the reinforcement plate 63. The reinforcement plate 63 is made of low alloy high strength steel. The reinforcement plate 63 made of low alloy high strength steel can improve the strength of the front end face of the gate body 5. The front end face of the reinforcement plate 63 is fixedly connected with a transverse reinforcement plate 61. Multiple transverse reinforcement plates 61 are fixedly connected. The transverse reinforcement plates 61 are made of low alloy high strength steel. Vertical reinforcement plates 62 are fixedly connected between the transverse reinforcement plates 61. Multiple vertical reinforcement plates 62 are fixedly connected. The vertical reinforcement plates 62 are made of low alloy high strength steel. Multiple vertical reinforcement plates 62 and transverse reinforcement plates 61 made of low alloy high strength steel can further improve the strength of the reinforcement plate 63, thereby preventing the gate body 5 from being easily deformed during use.

[0035] Fixed screws 64 are symmetrically installed on the left and right sides of the reinforcing plate 63. The fixed screws 64 are high-strength bolts. The fixed screws 64, which are high-strength bolts, will install or disassemble the reinforcing plate 63. A fixing nut 641 is installed on the rear side of the annular side of the fixed screw 64. The fixing nut 641 will install and fix the fixed screw 64. Fixed through holes 51 are symmetrically opened on the left and right sides of the gate body 5, and the fixed through holes 51 match the fixed screws 64. The fixed through holes 51 facilitate the fixed screws 64 to be inserted into the gate body 5 to install and fix the reinforcing plate 63.

[0036] Working principle: During the opening process of the gate body 5 (refer to Figure 2), the water will flow through the gate frame 2 from front to back. When the gate body 5 needs to be closed, the staff only needs to control the driving motor 31 to reverse, so that the driving motor 31 can drive the rotating worm 35 to reverse together. At this time, the rotating worm 35 will drive the driving worm wheel 36 to reverse, and the reversed driving worm wheel 36 will drive the rotating sleeve 37 to reverse together, so that the reversed rotating sleeve 37 drives the lifting screw rod 33 to move downward, and then the lifting screw rod 33 drives the gate body 5 to move downward through the connecting seat 34 to close. Similarly, when the driving motor 31 is controlled to rotate forward, the lifting screw rod 33 will drive the gate body 5 to move upward through the connecting seat 34 to open, and in this process The limit groove 4 will limit and guide the gate body 5 to prevent the gate body 5 from shaking or deflecting during the lifting process, while the follower ring 38 and the annular cover 321 prevent the rotating sleeve 37 from moving up and down or shaking during the rotation process; during the closing process of the gate body 5, the reinforcement plate 63 made of low-alloy high-strength steel can improve the strength of the front end face of the gate body 5, and at the same time, the multiple vertical reinforcement plates 62 and transverse reinforcement plates 61 made of low-alloy high-strength steel can further improve the strength of the reinforcement plate 63, thereby preventing the gate body 5 from being directly impacted by water flow or deformed by stone, thereby improving the service life of the gate body 5.
