Abstract
Description
Technical Field
[0001] This utility model relates to the field of lifting mechanism technology, and more specifically, to a two-end lifting mechanism for improving the water-blocking effect of the buoyancy module of a flood control gate. Background Technology
[0002] In urban flood control and water conservancy projects, floodgates are crucial facilities for resisting floods and ensuring regional safety. With the increasing frequency of extreme weather events and rapid urbanization, the threat posed by floods is becoming increasingly severe, placing higher demands on the performance of floodgates. To improve the water-blocking effect of floodgates, some new types of floodgates have adopted buoyancy modules. These modules automatically rise using the buoyancy of floodwaters, thereby increasing the water-blocking height of the floodgate. This design improves the adaptability and flood control capacity of floodgates to a certain extent. However, in actual operation, due to the complex and variable flow of floodwaters, existing buoyancy modules may experience uneven force distribution at both ends, leading to module tilting and affecting their water-blocking effect. To address the shortcomings of existing technologies, we propose a lifting mechanism at both ends to enhance the water-blocking effect of the buoyancy module in floodgates. Utility Model Content
[0003] In order to overcome the above-mentioned defects of the prior art, this utility model provides a lifting mechanism at both ends to improve the water-blocking effect of the buoyancy module of the floodgate, so as to solve the problem that the buoyancy module may be subjected to uneven force at both ends due to the complex and changeable flow state of floods, which may cause the module to tilt and thus affect its water-blocking effect.
[0004] To solve the above technical problems, this utility model provides the following technical solution: a lifting mechanism at both ends to improve the water-blocking effect of the buoyancy module of a flood control gate, including a wall, a lifting component is provided on the inner side of the wall, and a buoyancy module water-blocking component is provided on one side of the lifting component;
[0005] The lifting assembly includes a mounting block, an arc-shaped groove is formed on one outer surface of the mounting block, a water outlet is provided on the lower side of the arc-shaped groove, a limit post is slidably fitted to the outer wall of the arc-shaped groove, and a hydraulic rod is fixedly installed on one outer surface of the limit post.
[0006] The water outlet is located on one outer surface of the mounting block, the hydraulic rod is rotatably connected to the inner surface of the mounting block, and the mounting block is fixedly installed on the inner wall of the wall.
[0007] The buoyancy module water-blocking assembly includes a bottom load-bearing frame, with grids fixedly installed on both sides of the bottom load-bearing frame. A water-blocking plate is rotatably connected to the inner surface of the bottom load-bearing frame. A connecting shaft is fixedly installed on one outer surface of the water-blocking plate. A polyester buoyancy plate is fixedly installed on the lower outer surface of the water-blocking plate. A folding connecting rod is rotatably connected to one outer surface of the polyester buoyancy plate. The bottom load-bearing frame is attached to one outer surface of the mounting block. The connecting shaft slides on the outer wall of the arc-shaped groove. The water-blocking plate slides on one outer surface of the mounting block. One end of the folding connecting rod is rotatably connected to one inner wall of the bottom load-bearing frame.
[0008] There are two mounting blocks, which are symmetrically arranged at both ends of the bottom load-bearing frame on the inner wall of the wall.
[0009] The grid consists of two sections: one is an inlet grid, and the other is a backwater grid.
[0010] Compared with the prior art, the beneficial effects of this utility model are:
[0011] This utility model, through the setting of the lifting component, including the mounting block, activates the hydraulic rod to push the limiting column to slide along the outer wall of the arc groove. At this time, the limiting column pushes the connecting shaft to slide along the outer wall of the arc groove. Utilizing the above structure, by activating the hydraulic rod to push the limiting column to slide, the water baffle is lifted and limited, ensuring the force balance at both ends of the device, so that both ends are on the same horizontal line, avoiding module tilting, thereby greatly improving its water-blocking effect to a certain extent.
[0012] This utility model features a buoyancy module water-blocking component, including a bottom load-bearing frame. When water submerges the water-blocking plate, the buoyancy of the water on the polyester buoyancy plate causes it to rise, thereby rotating the water-blocking plate. The rotation of the water-blocking plate causes the folding connecting rod to rotate and support the water-blocking plate. Utilizing the above structure, the water-blocking plate automatically opens and closes to block water by means of the buoyancy principle of the polyester buoyancy plate. Moreover, the rotation angle of the water-blocking plate automatically changes with the water level, greatly improving the flexibility and practicality of the device. Attached Figure Description

[0020] As attached Figure 1 To be continued Figure 4 An embodiment of this utility model provides a two-end lifting mechanism to improve the water-blocking effect of the buoyancy module of a flood control gate, including a wall 1, a lifting component 2 provided on the inner side of the wall 1, and a buoyancy module water-blocking component 3 provided on one side of the lifting component 2.
[0021] The lifting assembly 2 includes a mounting block 21. An arc-shaped groove 22 is provided on one outer surface of the mounting block 21. A water outlet 23 is provided on the lower side of the arc-shaped groove 22. A limit post 24 is slidably attached to the outer wall of the arc-shaped groove 22. A hydraulic rod 25 is fixedly installed on one outer surface of the limit post 24.
[0022] The water outlet 23 is opened on one outer surface of the mounting block 21, the hydraulic rod 25 is rotatably connected to the inner surface of the mounting block 21, and the mounting block 21 is fixedly installed on the inner wall of the wall 1.
[0023] By activating the hydraulic rod 25, the limiting column 24 is pushed to slide along the outer wall of the arc groove 22. At this time, the limiting column 24 pushes the connecting shaft 34 to slide along the outer wall of the arc groove 22, thereby lifting and limiting the water baffle 33, ensuring the force balance at both ends of the device, so that both ends are on the same horizontal line, avoiding module tilting, and thus greatly improving its water-blocking effect to a certain extent.
[0024] The buoyancy module water-blocking component 3 includes a bottom load-bearing frame 31, with grids 32 fixedly installed on both sides of the bottom load-bearing frame 31. A water-blocking plate 33 is rotatably connected to the inner surface of the bottom load-bearing frame 31. A connecting shaft 34 is fixedly installed on one outer surface of the water-blocking plate 33. A polyester buoyancy plate 35 is fixedly installed on the lower outer surface of the water-blocking plate 33. A folding connecting rod 36 is rotatably connected to one outer surface of the polyester buoyancy plate 35. The bottom load-bearing frame 31 is attached to one outer surface of the mounting block 21. The connecting shaft 34 slides on the outer wall of the arc groove 22. The water-blocking plate 33 slides on one outer surface of the mounting block 21. One end of the folding connecting rod 36 is rotatably connected to one inner wall of the bottom load-bearing frame 31.
[0025] The water baffle 33 automatically opens and closes to block water by using the buoyancy principle of the polyester buoyancy plate 35. The rotation angle of the water baffle 33 changes automatically with the water level, which greatly improves the flexibility and practicality of the device.
[0026] There are two mounting blocks 21, which are symmetrically arranged at both ends of the bottom load-bearing frame 31 on the inner wall of the wall 1.
[0027] There are two grilles 32, one of which is an inlet grille and the other is a backwater grille.
[0028] The working process of this utility model is as follows:
[0029] During the use of this device, when the water flow submerges the baffle plate 33, the buoyancy of the water on the polyester buoyancy plate 35 causes the baffle plate 33 to rise, thereby rotating the baffle plate 33. The rotation of the baffle plate 33 drives the folding connecting rod 36 to rotate and support the baffle plate 33. The baffle plate 33 automatically opens and closes to block water through the buoyancy principle of the polyester buoyancy plate 35. Moreover, the rotation angle of the baffle plate 33 automatically changes with the water level, greatly improving the flexibility and practicality of the device. When the two ends of the baffle plate 33 are not on the same horizontal line, the hydraulic rod 25 is activated to push the limiting column 24 to slide along the outer wall of the arc groove 22. At this time, the limiting column 24 pushes the connecting shaft 34 to slide along the outer wall of the arc groove 22, realizing the lifting and limiting of the baffle plate 33, ensuring the force balance at both ends of the device, so that the two ends are on the same horizontal line, avoiding the module tilting, thereby greatly improving its water blocking effect to a certain extent.
