Description

Technical Field

[0001] The utility model relates to the technical field of lifting gates, in particular to a lifting gate for water conservancy projects. Background Art

[0002] Lifting gates are an important hydraulic structure, widely used in water conservancy projects, hydropower stations, ports, and chemical industries. Lifting gates change the gate height through the lifting mechanism at the bottom of the gate, thereby controlling the water level or water flow. The lifting mechanism is usually driven by hydraulic or electric motors, which can achieve rapid lifting and accurate control of the gate. The gate adopts a waterproof and sealed design to effectively prevent water leakage.

[0003] During the use of the gate, long-term water flow impact will cause the gate surface material to wear, especially in areas with high water flow speed and strong impact force, the wear is more serious. This will cause the gate to reduce its structural strength due to wear and deformation, increase the risk of fracture, and thus reduce the safety of the lifting gate. Utility Model Content

[0007] In addition, a preferred structure is that hydraulic rod assemblies are fixedly provided on both sides of the top of the lifting gate body, and the top extending ends of the hydraulic rod assemblies extend to the rear of the lifting gate body and are connected to the movable plate.

[0008] In addition, a preferred structure is that a plurality of mounting columns are fixedly and vertically arranged at the bottom of the movable plate, and the mounting columns are all facing the gate assembly.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-6A lifting gate for water conservancy projects includes a lifting gate body 1 and a protective plate 2. A driving mechanism 11 is fixedly arranged on the top of the lifting gate body 1. A gate assembly 12 is movably arranged below the lifting gate body 1 through the driving mechanism 11, and a detachable protective plate 2 is assembled in front of the gate assembly 12. A plurality of fixed seats 21 are fixedly arranged on the top of the protective plate 2. Limiting columns 22 are fixedly arranged vertically downward on the outer sides of the fixing seats 21, and corresponding limiting columns 22 on the gate assembly 12 are adapted to open limiting cavities 13.

[0022] Among them, the gate assembly 12 can be moved up and down by setting the driving mechanism 11 on the lifting gate body 1. It is worth noting that the specific structures and working methods of the lifting gate body 1, the driving mechanism 11 and the gate assembly 12 are all existing technologies currently disclosed on the market, which are common knowledge known to those skilled in the art and are not the main technical problems to be solved in this technical solution, so they are not elaborated in this utility model.

[0023] Among them, hydraulic rod assemblies 3 are fixedly arranged on both sides of the top of the lifting gate body 1, and the top extension ends of the hydraulic rod assemblies 3 are extended to the rear of the lifting gate body 1 and connected to the movable plate 31. A plurality of mounting columns 32 are fixedly and vertically arranged at the bottom of the movable plate 31, and the mounting columns 32 are all facing the gate assembly 12. Through the connection between the hydraulic rod assembly 3 and the movable plate 31, the mounting columns 32 can be controlled to move synchronously.

[0024] Among them, a horizontal plate 4 is fixedly arranged below the lifting gate body 1, and through holes 41 are adapted to be opened on the horizontal plate 4 corresponding to the mounting columns 32. Mounting cavities 23 are opened on the fixing seat 21 corresponding to the mounting columns 32, and the mounting cavities 23 are adapted to the mounting columns 32. The mounting columns 32 pass through the through holes 41 and are inserted into the mounting cavities 23, so that the protective plate 2 can be lifted by the mutual clamping between the mounting columns 32 and the mounting cavities 23.

[0025] Among them, a silicone layer is laid on one side of the protective plate 2 that contacts the gate assembly 12, and the other sides of the protective plate 2 are laid with a wear-resistant layer. By setting the silicone layer, the friction between the protective plate 2 and the gate assembly 12 can be reduced, thereby increasing the service life of the gate assembly 12. By setting the wear-resistant layer, the damage to the protective plate 2 caused by the impact of water flow can be reduced, thereby increasing the service life of the protective plate 2. It is also worth noting that the specific structure of the silicone layer and the wear-resistant bin and their working methods are all existing technologies currently disclosed on the market, which are common knowledge known to those skilled in the art, and do not belong to the main technical problems to be solved in this technical solution, so they are not elaborated in this utility model.

[0026] In the present invention, when the user needs to install the protective plate 2, the installation cavity 23 on the protective plate 2 can be aligned with the through hole 41 on the horizontal plate 4, and then the movable plate 31 can be controlled by the hydraulic rod assembly 3 to drive the installation column 32 to move toward the through hole 41. When the installation column 32 passes through the through hole 41 and is inserted into the installation cavity 23, the protective plate can be lifted and positioned by the installation column 32.

[0027] Then the user can control the gate assembly 12 to move upward through the driving mechanism 11. When the gate assembly 12 moves upward, the limiting pillars 22 can be inserted into the limiting cavity 13 to achieve the installation of the protective plate 2. Finally, the movable plate 31 can be reset by controlling the hydraulic rod assembly 3. In addition, due to the gravity of the protective plate 2 itself and the setting of the silicone sleeve on the contact surface of the protective plate 2 with the gate assembly 12, the stability of the protective plate 2 after installation can be guaranteed.

[0028] Furthermore, when the user needs to disassemble and replace the protective plate 2, the user only needs to control the gate assembly 12 to move upward through the driving mechanism 11. When the installation cavity 23 on the protective plate 2 contacts the through hole 41 again, the user only needs to control the installation column 32 to be inserted into the installation cavity 23 again through the hydraulic rod assembly 3, so as to lift the protective plate 2 again. Finally, the removal and replacement of the protective plate 2 can be achieved through an external machine. The gate assembly 12 can be protected by the setting of the protective plate 2. When the protective plate 2 is worn, it only needs to be replaced.

[0029] Furthermore, when the user installs or disassembles the protective plate 2, external mechanical assistance is required to ensure the stability of the protective plate 2 during assembly or disassembly.

[0030] In the utility model, the gate assembly 12 in the lifting gate body 1 can be controlled to move up and down through the driving mechanism 11. The gate assembly 12 can be protected by the setting of the protective plate 2, so as to prevent it from being worn by the impact of water flow. When the protective plate 2 is subjected to a lot of wear, it is only necessary to replace the protective plate 2. In this way, the gate assembly 12 can be protected, thereby improving the safety of the lifting gate body 1.

[0031] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
