Description

Technical Field

[0001] This utility model relates to a cleaning tool for large-diameter water conveyance tunnels. Background Technology

[0002] Large-diameter water conveyance tunnels located in subtropical monsoon climates are prone to crustacean growth (such as barnacles and shellfish larvae, especially during their attachment period) on their inner walls. These crustaceans have a strong attachment ability, with some accumulating to a thickness of up to 20 cm. Cleaning the tunnel arch is particularly difficult, posing significant challenges to tunnel maintenance and cleaning. Biofouling on the inner walls of large-diameter water conveyance tunnels is a global problem. While international research on biofouling removal from underwater structures (including pipelines, ship hulls, and offshore platforms) is active, technologies specifically targeting crustaceans on the inner walls of large-diameter water conveyance tunnels are relatively scarce. Currently, conventional manual removal methods are still used, which are not only inefficient and result in large amounts of residue, but also expose the tunnel to the high temperature, high humidity, and foul odors of the tunnel interior. Furthermore, the metal tips of the cleaning tools may damage the anti-corrosion coating on the tunnel walls. Summary of the Invention

[0003] The problem this invention aims to solve is to provide a cleaning tool for large-diameter water conveyance tunnels, overcoming the shortcomings of existing technologies.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a cleaning fixture for a large-diameter water conveyance tunnel, including a base, a vertical frame, an arc-shaped rubber plate and two arc-shaped steel plates. The base has two square holes on its side parallel to the vertical frame that can be used with forks on a forklift. The vertical frame is fixed to the base. The two arc-shaped steel plates clamp the arc-shaped rubber plate and are fixed with bolts and fixed to the top of the vertical frame. The upper edge of the arc-shaped rubber plate extends above the upper edge of the arc-shaped steel plate.

[0016] like Figure 1 As shown, this utility model provides a cleaning fixture for a large-diameter water conveyance tunnel, including a base, a vertical frame, a diagonal brace, an arc-shaped rubber plate 1, and two arc-shaped steel plates 2. The base is a frame structure composed of two bottom hollow square steels 6 and two bottom transverse steels (bottom transverse channel steels 5 and bottom transverse angle steels 7). The bottom hollow square steels 6 can be used with the forks on a forklift. The bottom hollow square steels and the bottom transverse steels are perpendicular to each other. The vertical frame includes multiple vertical steels (vertical channel steels 4) spaced apart. The lower end of the vertical channel steel 4 is fixed to the bottom transverse channel steel 5 of the base, and the upper end is fixed to the arc-shaped steel plate 2. The diagonal brace includes multiple diagonal support angle steels 8 spaced apart. The upper end of the diagonal support angle steel 8 is fixed to the upper part of the vertical channel steel 4, and the lower end is fixed to the bottom hollow square steels 6 on the base. Two curved steel plates 2 clamp the curved rubber plate 1 and fix it with bolt group 3, and fix it to the top of the vertical channel steel 4. The upper edge of the curved rubber plate 1 extends above the upper edge of the curved steel plate 2.

[0017] To effectively remove crustaceans adhering to the tunnel walls without damaging them, the aforementioned structure uses rubber as the end-cleaning material. Rubber's high elasticity and certain hardness ensure effective removal of crustaceans without harming the tunnel walls. Two curved steel plates 2 clamp a curved rubber plate 1, which is then secured with a set of curved bolts 3. The curved rubber plate 1 protrudes slightly to ensure contact with the deposits on the tunnel walls, achieving the end-cleaning purpose. Since the end-cleaning device must be vertically positioned and horizontally movable, a hollow square steel bar 6 is specifically designed at the bottom of the device to improve its cleaning efficiency. This hollow square steel bar 6 allows for the insertion of forklift forks, facilitating the device's movement and transportation during construction. To ensure the stability of the overall structure, the cleaning end device is fixed to the bottom hollow square steel 6 by three vertical channel steels 4 and bottom horizontal channel steel 5. At the same time, three diagonal support angle steels 8 ensure that the tooling is triangular and stable. The bottom of the tooling is a rectangular plane to ensure stability after the forklift extends in. All steel structure connections are welded.

[0018] The aforementioned tooling needs to be used in conjunction with a forklift. During operation, the forklift forks are fully inserted into the hollow square steel 6 at the bottom of the tooling from one of the right-angle sides. The tooling is then lifted to a suitable height by the forklift and entered into the tunnel through the tunnel access forklift. The tooling is then lifted to the top of the tunnel so that the curved rubber plate 1 fits against the inner wall of the tunnel. The uniform movement of the forklift causes the rubber plate and the attached material on the inner wall of the tunnel to interact, peeling the attached material off the inner wall of the tunnel and causing it to fall to the bottom of the tunnel roadway for collection and cleaning.

[0019] Because the rubber arc plate 1 will wear out after a period of use, it needs to be removed from between the two arc steel plates 2 and the size of its protruding part needs to be adjusted. However, after the arc rubber plate 1 is clamped between the arc steel plates 2 for a long time, it is easy to stick to the arc steel plates 2, and it is easily damaged during disassembly. To avoid this problem, improvements were made to the above structure, such as... Figure 2 , Figure 3 As shown, each arc-shaped steel plate 2 has an arc-shaped pad 2-1 inside. The arc-shaped pad 2-1 is fixed to the inner side of the arc-shaped steel plate 2. The upper edge of the arc-shaped pad 2-1 is located between the upper edge of the arc-shaped steel plate 2 and the upper edge of the arc-shaped rubber plate 1, and the lower edge is located on the inner wall of the arc-shaped steel plate 2 near the upper edge of the arc-shaped steel plate 2. The arc-shaped pad reduces the contact area of ​​the arc-shaped rubber plate 1, making it easier to remove the arc-shaped rubber plate 1 from between the arc-shaped steel plates 2. Multiple roller spikes 2-2 are arranged at intervals on the outer side of the arc-shaped pad 2-1, above the upper edge of the arc-shaped steel plate 2. The outer end of the roller spike 2-2 faces obliquely upward, and the height of the outer end of the roller spike 2-2 is lower than the height of the upper edge of the arc-shaped rubber plate 1. The arrangement of the roller spikes 2-2 can assist the arc-shaped rubber plate 1 in cleaning the suspended parts of the attachments on the inner wall of the tunnel that are not in contact with the inner wall of the tunnel.

[0020] The top surface of the arc-shaped pad 2-1 is a slope 2-3, which extends obliquely downward from the position where the arc-shaped pad 2-1 contacts the arc-shaped rubber plate 1 towards the outer side of the arc-shaped pad 2-1.

[0021] The embodiments of this utility model have been described in detail above, but the content described is only a preferred embodiment of this utility model and should not be considered as limiting the scope of implementation of this utility model. All equivalent changes and improvements made in accordance with the claims of this utility model should still fall within the patent coverage of this utility model.
