DETAILED DESCRIPTION

[0025] 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.

[0026] Reference Figure 1-4 A lifting type hydraulic gate comprises a frame 1 and a gate 2, wherein the gate 2 is slidably mounted inside the frame 1, and a driving mechanism 3 for driving the gate 2 to be lifted is provided at the upper end of the frame 1. The gate 2 is lifted and lowered by the driving mechanism 3 to control the opening and closing state of the gate 2.

[0027] A plurality of slide posts 4 are vertically installed in the frame 1, and the slide posts 4 pass through the gate 2 and are slidably connected to the gate 2. The slide posts 4 ensure the stability of the gate 2 in lifting and sliding, and limit the gate 2 to ensure the closing effect of the gate 2 on the frame 1, so as to avoid water leakage and other situations that affect the closing effect of the gate 2.

[0028] A protective net 6 is fixedly provided on the front side of the frame 1, and a scraper 62 is slidably provided on the front side of the protective net 6. A plurality of connecting rods 621 are connected between the scraper 62 and the gate 2, and a plurality of strip-shaped slide grooves 61 are provided on the protective net 6 corresponding to the connecting rods 621. In order to prevent floating garbage in the water body from flowing out when the gate is opened to release water, the floating objects such as garbage are filtered by the protective net 6 when the gate 2 is opened, so as to facilitate the collection and treatment of the garbage. And through the design of the scraper 62, when the gate 2 is raised or lowered, the scraper 62 is driven by the connecting rod 621 to rise and fall and slide to scrape the attached objects such as mud or moss on the protective net 6, so that the attached objects fall off and are conveniently washed by water flow during waterproofing to avoid the blockage of the protective net 6, thereby ensuring the use effect of the protective net 6.

[0029] Based on the above technical solution, when the gate 2 is in use, the gate 2 can be opened and closed by driving the gate 2 up and down through the driving mechanism 3. When the gate 2 is opened and closed, the sliding column 4 ensures the stability of the opening and closing of the gate 2. When the gate 2 is raised and lowered, the scraper 62 is driven by the connecting rod 621 to scrape the attachments on the surface of the protective net 6, and the protective net 6 is flushed with the water flow, which facilitates the cleaning of the protective net 6, ensures the use effect of the protective net 6, and avoids affecting the smooth outflow of water.

[0030] In this technical solution, if Figure 2-4 As shown, a lubrication mechanism 5 is provided on the sliding column 4 corresponding to the rear side of the gate 2. The sliding column 4 is lubricated by the lubrication mechanism 5 to ensure smooth and stable sliding of the gate 2. For the sliding column 4 made of rust-prone materials, its anti-rust effect can be improved by lubrication.

[0031] In this technical solution, if Figure 2-4As shown, the lubrication mechanism 5 includes a plurality of mounting grooves 50 provided on the rear side of the gate 2, a rotating seat 51 is fixedly installed in the mounting groove 50, a threaded sleeve 52 is rotatably installed on the rotating seat 51, the threaded sleeve 52 is sleeved on the sliding column 4, and a threaded groove 41 matching the threaded sleeve 52 is provided on the sliding column 4; the threaded sleeve 52 is connected to a coating brush 53 in an annular shape sleeved on the sliding column 4, and the inner side of the coating brush 53 is filled with grease.

[0032] When the gate 2 is raised or lowered, the threaded sleeve 52 is driven to slide on the slide post 4. The threaded sleeve 52 rotates by the cooperation with the thread groove 41, and then drives the coating brush 53 to rotate, cleans the surface of the slide post 4 and applies grease, so as to ensure the smooth sliding of the slide post 4.

[0033] In this technical solution, if Figure 2-4 As shown, an oil storage tank 54 for storing lubricating oil is connected to one side of the rotating seat 51. Lubricating grease is supplied to the rotating seat 51 through the oil storage tank 54, and then the lubricating grease is applied to the sliding column 4 with the coating brush 53 to ensure the lubrication effect of the sliding column 4.

[0034] In this technical solution, if Figure 2-4 As shown, the plurality of mounting grooves 50 are respectively arranged on the upper and lower sides of the gate 2. By arranging a plurality of coating brushes 53 on the upper and lower sides of the gate 2, it is ensured that the upper and lower sides of the slide column 4 can be coated when the gate 2 is raised or lowered, thereby ensuring a comprehensive coating effect on the slide column 4, and ensuring a rust-proof and lubricating effect on the slide column 4.

[0035] In this technical solution, if Figure 1-4 As shown, the driving mechanism 3 includes a cable 31, a winding wheel 32, a reducer 33 and a motor 34. One end of the cable 31 is fixedly connected to the upper end of the gate 2, and the other end of the cable 31 passes through the frame 1 and is wound on the winding wheel 32. The winding wheel 32 is connected to the output end of the reducer 33, and the input end of the reducer 33 is connected to the output end of the motor 34. The output torque of the motor 34 is increased by the reducer 33 to ensure the stable lifting and lowering of the gate 2 and the opening and closing effect of the gate 2.

[0036] In this technical solution, if Figure 1-4 As shown, the cable 31 and the corresponding winding wheel 32 are provided in plurality to ensure that the force distribution between the cable 31 and the gate 2 is uniform when the gate 2 is raised or lowered, to avoid uneven force affecting the lifting stability of the gate 2, and to ensure the lifting effect of the gate 2.

[0037] 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.
