Description

Technical Field

[0001] This utility model belongs to the technical field of water conservancy engineering equipment, and specifically relates to a novel gate sealing structure. Background Technology

[0002] In water conservancy projects, the sealing performance of gates is crucial for the effective utilization of water resources and the normal operation of water conservancy facilities. Existing gate sealing structures have several problems. For example, sealing components are prone to wear during long-term use, leading to a decrease in sealing effectiveness; some sealing structures cannot adaptively adjust the sealing degree under different water pressure conditions, affecting the overall performance of the gate. Therefore, an innovative sealing structure is needed to solve these problems and improve the sealing reliability and durability of gates. Summary of the Invention

[0003] To overcome the shortcomings of the prior art, this utility model provides a novel gate sealing structure.

[0004] This utility model is achieved through the following technical solution:

[0005] A novel gate sealing structure includes a gate frame and a gate plate that can move up and down along the gate frame. The gate plate is characterized by having a high molecular weight polyethylene protrusion installed on its side, and a EPDM rubber concave block that is tightly attached to the groove of the gate frame. The high molecular weight polyethylene protrusion extends into the EPDM rubber concave block, and a gap is left between the high molecular weight polyethylene protrusion and the EPDM rubber concave block.

[0006] The high molecular weight polyethylene protrusion has extension plates integrally installed on both sides of the gate plate.

[0007] The inner side of the EPDM rubber concave block is provided with several fixing plates, and screws are inserted through the fixing plates. The screws are fixed to the gate frame by nuts.

[0008] Fastening screws are inserted into several countersunk holes on the high molecular weight polyethylene protrusion, and the fastening screws are fixed to the side of the gate plate by fastening nuts.

[0009] The beneficial effects of this invention are: it can automatically adjust the sealing pressure according to the water pressure; the higher the water pressure, the greater the gate displacement, the greater the extrusion pressure, and the better the sealing effect, effectively solving the problem of unstable sealing in traditional sealing structures under different water pressures. High-molecular-weight polyethylene has good wear resistance, and when used in conjunction with EPDM sealing components, it reduces wear between sealing parts while ensuring a good sealing effect, extending the service life of the sealing structure. The reserved gaps ensure that the gate is not obstructed during its up-and-down movement, guaranteeing the normal operation of the gate. Attached Figure Description

[0010] The present invention will be further described below with reference to the accompanying drawings.

[0011] Appendix Figure 1 This is a schematic diagram of the structure of this utility model;

[0012] In the diagram, 1 is the gate frame, 2 is the gate plate, 3 is the high molecular weight polyethylene protrusion, 4 is the groove, 5 is the EPDM rubber concave block, 6 is the extension plate, 7 is the fixing plate, 8 is the screw, 9 is the nut, 10 is the fastening screw, and 11 is the fastening nut. Detailed Implementation

[0013] The attached figure shows a specific embodiment of this utility model. This embodiment includes a gate frame 1 and a gate plate 2 that can move up and down along the gate frame 1. A high-molecular-weight polyethylene (PMPE) protrusion 3 is installed on the side of the gate plate 2. An EPDM rubber concave block 5 is provided within a groove 4 of the gate frame 1, closely fitting the groove 4. The PMPE protrusion 3 extends into the EPDM rubber concave block 5, with a gap between the PMPE protrusion 3 and the EPDM rubber concave block 5. Extension plates 6 are integrally mounted on the gate plate 2 on both sides of the PMPE protrusion 3. Several fixing plates 7 are provided inside the EPDM rubber concave block 5, with screws 8 passing through the fixing plates 7. The screws 8 are fixed to the gate frame 1 by nuts 9. Fastening screws 10 are inserted into several countersunk holes on the PMPE protrusion 3, and the fastening screws 10 are fixed to the side of the gate plate 2 by fastening nuts 11.

[0014] The novel gate sealing structure of this invention precisely installs the high-molecular-weight polyethylene protrusion 3 slide rails on both sides of the gate plate 2, ensuring the installation accuracy and flatness of the slide rails and guaranteeing that the size and shape of the convex shape meet the design requirements. Simultaneously, the EPDM rubber concave seal 5 is accurately installed in the corresponding grooves 4 on both sides of the gate frame 1, ensuring that the size and shape of the concave shape match the slide rails. After installation, the relative position between the gate plate 2 and the gate frame 1 is checked to ensure that the reserved gaps are uniform in size and do not affect the up-and-down movement of the gate. When the gate is subjected to water pressure, the gate plate 2 is displaced under the pressure. As the gate plate 2 displaces, the convex-shaped high-molecular-weight polyethylene protrusion 3 slide rails gradually enter the concave-shaped EPDM rubber concave seal 5 and compress it. During this process, the seal undergoes a certain deformation, filling any gaps and achieving a seal. When the water pressure changes, the displacement of the gate plate 2 also changes accordingly, and the compressive force on the seal is adjusted accordingly, maintaining a good sealing effect at all times.
