Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, specifically to a water conservancy gate sealing device. Background Technology

[0002] Hydraulic gates are important facilities in water conservancy projects, used to control the flow of water and regulate water levels. The sealing performance of the gates directly affects the normal operation of the water conservancy project. Poor sealing can lead to water leakage, wasting water resources and potentially causing erosion and damage to the gates and surrounding facilities.

[0003] Traditional gate seals mostly use a single rubber sealing strip, which achieves sealing by deformation caused by compression when the gate is closed. However, the rubber sealing strip rubs against the gate frame for a long time, especially in water containing silt, which aggravates wear and leads to rapid seal failure. To ensure the sealing effect, it needs to be replaced frequently, increasing the cost of use. Utility Model Content

[0006] A spiral-shaped panel, which is slidably connected within the door frame;

[0007] A sealing mechanism, wherein four sealing mechanisms are respectively fixedly connected to the four corners of the door frame;

[0008] The sealing mechanism includes a square column, an inclined groove, a sliding column, a first lead screw, a first motor, and a triangular column;

[0009] The square column is slidably connected to the four corners of the door frame and its ends are fixedly connected to the four corners of the U-shaped plate. The inclined groove is opened at the other end of the square column. The sliding column is slidably connected to the four corners of the door frame.

The first lead screw is threadedly connected to the sliding column.

[0010] Furthermore, the inclined surface of the inclined groove has a groove, and the inclined surface of the triangular prism is fixedly connected to an inclined column, which slides within the groove.

[0011] Furthermore, the sealing mechanism also includes a spring, the two ends of which are fixedly connected to the four corners of the U-shaped plate and the four corners inside the door frame, respectively.

[0012] Furthermore, the sealing mechanism also includes a sliding groove, which is opened at the four corners of the outer side of the door frame. A convex plate is fixedly connected to the side wall of the sliding column, and the convex plate slides in the sliding groove.

[0013] Furthermore, it also includes anti-loosening mechanisms, of which four are respectively installed at the four corners of the outer side of the door frame. The anti-loosening mechanisms include square tubes, square plates, stop posts, and telescopic posts.

[0014] The square tube is fixedly connected to the four corners of the outside of the door frame, the square plate is slidably connected inside the square tube, the stop post is fixedly connected to one side of the square plate, and the two ends of the telescopic post are respectively fixedly connected to the side wall of the square tube and the other side of the square plate.

[0017] This utility model has the following beneficial effects:

[0018] This invention utilizes a first motor to drive a first lead screw to rotate, which in turn drives a sliding column to slide. The sliding column then drives a triangular prism to slide, causing the inclined surface of the triangular prism and the inclined surface groove to slide. This causes the inclined surface groove to slide inward toward the gate frame, which in turn drives a U-shaped plate to slide. This U-shaped plate then presses tightly against the gate, pushing the gate against the gate frame and sealing the gap between the gate and the gate frame. This invention replaces traditional rubber sealing strips, improving durability while requiring minimal maintenance and thus reducing operating costs. Attached Figure Description

[0029] To make the objectives, technical solutions and advantages of this utility model clearer, the preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0030] Please see Figure 1-4 As shown, this utility model is a sealing device for a hydraulic gate, comprising:

[0031] A spiral plate 100 is slidably connected inside the door frame;

[0032] The sealing mechanism 200 consists of four parts, which are respectively fixedly connected to the four corners of the door frame.

[0033] The sealing mechanism 200 includes a square column 210, an inclined groove 220, a sliding column 230, a first lead screw 240, a first motor 250, and a triangular column 260;

[0034] Square column 210 is slidably connected to the four corners of the door frame and its ends are fixedly connected to the four corners of the U-shaped plate 100. Inclined groove 220 is formed at the other end of square column 210. Sliding column 230 is slidably connected to the four corners of the door frame. Triangular column 260 is fixedly connected to the end of sliding column 230. The inclined surface of triangular column 260 is slidably connected to the inclined surface of inclined groove 220. First motor 250 is fixedly connected to the four corners of the door frame. First lead screw 240 is fixedly connected to the power output end of first motor 250. The first lead screw 240 is threadedly connected to the sliding column 230. The first motor 250 drives the first lead screw 240 to rotate, which in turn drives the sliding column 230 to slide. The sliding column 230 drives the triangular prism 260 to slide, causing the inclined surface of the triangular prism 260 and the inclined surface of the inclined groove 220 to slide. This causes the inclined groove 220 to slide towards the inside of the gate frame, and the inclined groove 220 drives the sliding plate 100 to slide. This causes the sliding plate 100 to press tightly against the gate and push the gate to press tightly against the gate frame.

[0035] The inclined groove 220 has a groove 221 on its inclined surface. The inclined surface of the triangular prism 260 is fixedly connected to the inclined column 261. The inclined column 261 slides in the groove 221. The sliding column 230 drives the triangular prism 260 to slide, so that the inclined column 261 slides in the groove 221, so that the triangular prism 260 is connected to the inclined surface of the inclined groove 220, and the sliding column 230 can drive the square column 210 to slide through the triangular prism 260.

[0036] The sealing mechanism 200 also includes a spring 270. The two ends of the spring 270 are fixedly connected to the four corners of the U-shaped plate 100 and the four corners inside the door frame, respectively. In the initial state, the spring 270 is in a compressed state. When the square column 210 slides and drives the U-shaped plate 100 to slide, the spring 270 rebounds to provide additional power for the square column 210 to slide, so that the square column 210 can slide smoothly.

[0037] The sealing mechanism 200 also includes a slide groove 280, which is opened at the four corners of the outer side of the door frame. A protruding plate 231 is fixedly connected to the side wall of the slide column 230. The protruding plate 231 slides in the slide groove 280. The sliding of the slide column 230 drives the protruding plate 231 to slide in the slide groove 280, so that the slide column 230 can only slide and cannot rotate with the first motor 250.

[0038] Working principle: The first motor 250 drives the first lead screw 240 to rotate, the first lead screw 240 drives the sliding column 230 to slide, causing the convex plate 231 to slide in the sliding groove 280. The sliding column 230 drives the triangular column 260 to slide, causing the inclined column 261 to slide in the groove 221, thereby causing the inclined groove 220 to slide inward to the door frame. The inclined groove 220 drives the U-shaped plate 100 to slide, so that the U-shaped plate 100 is in close contact with the gate, pushing the gate to be in close contact with the door frame, thus sealing the gap between the gate and the door frame. This replaces the traditional rubber sealing strip, improves durability, and requires less maintenance, thereby reducing the cost of use.

[0039] Please see Figure 1-4As shown, this embodiment is based on the above embodiment:

[0040] Anti-loosening mechanism 300, there are four anti-loosening mechanisms 300 respectively installed at the four corners of the outside of the door frame. Anti-loosening mechanism 300 includes square tube 310, square plate 320, stop post 330, and telescopic post 340.

[0041] The square tube 310 is fixedly connected to the four corners of the outer side of the door frame. The square plate 320 is slidably connected inside the square tube 310. The stop post 330 is fixedly connected to one side of the square plate 320. The telescopic post 340 is fixedly connected to the side wall of the square tube 310 and the other side of the square plate 320 at both ends, respectively. When the U-shaped plate 100 pushes the gate to fit tightly against the door frame, it pushes the square plate 320 to slide, causing the square tube 310 to lengthen. The square plate 320 drives the stop post 330 to slide out of the square tube 310 and block the end of the square post 210, preventing the square post 210 from sliding outward and causing the seal between the gate and the door frame to loosen.

[0042] The square tube 310 has an opening groove 311 on its surface, and a push plate 321 is fixedly connected to the side wall of the square plate 320. The push plate 321 is slidably connected in the opening groove 311. By pushing the push plate 321 to slide in the opening groove 311, the square plate 320 can be easily slid.

[0043] A side plate 351 is fixedly connected to the surface of the square tube 310. A second motor 352 is fixedly connected to one side of the side plate 351. A second lead screw 353 is fixedly connected to the power output end of the second motor 352. The second lead screw 353 is threadedly connected to the push plate 321. When the second motor 352 is started, it drives the second lead screw 353 to rotate. The rotation of the second lead screw 353 drives the push plate 321 to slide in the opening slot 311, so that the push plate 321 automatically slides and drives the square plate 320 to slide.

[0044] Working principle: When the U-shaped plate 100 pushes the gate to fit tightly against the gate frame, the second motor 352 is started to drive the second lead screw 353 to rotate. The rotation of the second lead screw 353 drives the push plate 321 to slide in the opening slot 311, pushing the square plate 320 to slide and causing the square tube 310 to lengthen. The square plate 320 drives the stop column 330 to slide out of the square tube 310 and block the end of the square column 210, preventing the square column 210 from sliding outward and causing the gate and gate frame to loosen their seal.
