Description

Technical Field

[0001] This utility model relates to the field of gate technology for water conservancy projects, and in particular to an impact-resistant structure for gates used in water conservancy projects. Background Technology

[0002] Gates are control facilities used to close and open water discharge channels. They are an important component of hydraulic structures and can be used to intercept water flow, control water level, regulate flow, and discharge sediment and floating debris.

[0003] In the existing technology, the gates used in water conservancy projects are subject to the impact of water flow during use. The impact force of the water flow on the gate will have a certain impact on the gate itself, thereby affecting the gate's control effect. Secondly, impurities in the water flow will continuously scour the water-facing surface of the gate, and long-term scour will cause certain damage to the gate. When maintaining damaged gates, the gate leaf is often replaced. The traditional method of replacing the entire gate increases the maintenance cost. Utility Model Content

[0026] In one embodiment, both sides of the inner wall of the fixed frame 1 are fixedly connected to one side of the buffer frame 401, and the buffer frame 401 has a buffer groove 402 inside.

[0027] Specifically: the impact force is buffered by the damping of the damping block 404 and the damping ring 405 through the buffer spring 403 and the rubber pad 406.

[0028] In one embodiment, the inner wall of the buffer groove 402 is fixedly connected to one end of the buffer spring 403, and the other end of the buffer spring 403 is fixedly connected to one end of the damping block 404.

[0029] Specifically: The impact force causes the door leaf body 501 to squeeze the damping block 404 and the rubber pad 406, which in turn causes the damping block 404 to squeeze the buffer spring 403.

[0030] In one embodiment, the outer wall of the damping block 404 is movably connected to the inner wall of the buffer groove 402, and the outer wall of the damping block 404 is fixedly connected to the inner wall of the damping ring 405. One side of the buffer frame 401 is fixedly connected to one side of the rubber pad 406.

[0031] Specifically, it increased the device's impact resistance and reduced the impact of water flow on the device.

[0032] In one embodiment, the inner wall of the sealing groove 3 is movably connected to the outer wall of the door leaf body 501, and the outer wall of the door leaf body 501 is provided with an installation groove 502.

[0033] Specifically, the installation slot 502 facilitates the installation and removal of the anti-scouring plate 506.

[0039] Specifically, by replacing the anti-scouring plate 506, the traditional method of replacing the entire door leaf is eliminated, thus reducing maintenance costs.

[0040] Working principle: When the gate leaf body 501 is impacted by water flow, the impact force causes the gate leaf body 501 to squeeze the damping block 404 and the rubber pad 406, which in turn causes the damping block 404 to squeeze the buffer spring 403. Through the damping of the damping block 404 and the damping ring 405, the impact force is buffered by the buffer spring 403 and the rubber pad 406. When impurities in the water flow flush the device, the anti-scour plate 506 is flushed first. As the device is used for a longer period of time, the anti-scour plate 506 will be partially damaged. When replacing the anti-scour plate 506, use tools to remove the fastening bolt 509 and then remove the anti-scour plate 506. The new anti-scour plate 506 is installed on one side of the gate leaf body 501 by the positioning block 507. Then, use tools to install the fastening bolt 509, thereby replacing the anti-scour plate 506.
