Description

Technical Field

[0001] This utility model relates to the field of high-voltage power culvert technology, specifically to an in-situ protection structure for high-voltage power culverts. Background Technology

[0002] High-voltage power culverts are key facilities used for the laying and protection of high-voltage power cables. In-situ protection structures for high-voltage power culverts provide on-site protection for existing high-voltage power culverts during construction. These structures are primarily used in subway and foundation pit projects to avoid the high costs and delays associated with relocation. For example, patent application number 202020599716.9, entitled "An In-situ Protection Structure for High-Voltage Power Culverts," includes a placement frame. The top of the placement frame is movably connected to the high-voltage power culvert body. A first protective sleeve is provided on the left side of the high-voltage power culvert body. The left side extends into the interior of the first protective sleeve, and the right side of the high-voltage power culvert body is provided with a second protective sleeve. This utility model connects the first and second protective sleeves by setting a positioning mechanism to prevent them from separating. The first and second protective sleeves protect the high-voltage power culvert body and prevent it from being easily damaged by external objects or falling objects when placed. This achieves the effect of protecting the high-voltage power culvert when it is placed on the placement rack, and solves the problem of not being able to protect the high-voltage power culvert when it is placed on the placement rack.

[0003] The aforementioned technologies have the following drawbacks: the in-situ protection structure for high-voltage power culverts protects the culverts using a first and second protective sleeve, but this protection has poor impact resistance. When the in-situ protection structure is impacted, the impact force is transmitted to the high-voltage power culvert, causing it to break and thus reducing its practicality.

[0004] Therefore, it is necessary to design and modify the in-situ protection structure of high-voltage power culverts to effectively prevent their low practicality. Utility Model Content

A limit mechanism is provided on the surface of the telescopic rod 12.

[0019] As a technical optimization of this utility model, by setting up the telescopic rod 12 and the storage rack 13, the compression spring 7, the connecting block 8 and the clamping plate 9 are guided to avoid the compression spring 7, the connecting block 8 and the clamping plate 9 from tilting, thereby affecting the protection effect of the high-voltage power culvert in-situ protection structure on the culvert body 1.

[0020] refer to Figure 4 The limiting mechanism includes a limiting frame 14 fixedly connected to the surface of the telescopic rod 12 and located inside the storage rack 13. A ball bearing 15 is movably connected to the outer side of the limiting frame 14, and the outer side of the ball bearing 15 is movably connected to the inner wall of the storage rack 13.

[0021] As a technical optimization of this utility model, by setting a limiting frame 14, the telescopic rod 12 is limited to prevent the telescopic rod 12 from separating from the storage rack 13, and the ball bearing 15 is used to protect the limiting frame 14 to prevent friction between the limiting frame 14 and the storage rack 13, thereby extending the service life of the limiting frame 14.

A sealing strip 19 is fixedly connected inside the mounting groove 18.

[0028] The working principle and usage process of this utility model are as follows: In use, the fixing frame 2 and the support frame 3 are first placed on the culvert body 1, and the limiting block 5 is inserted into the positioning groove 4. Then, hot melt adhesive is delivered into the positioning groove 4 through the injection hole 16. After the hot melt adhesive solidifies, it will connect the fixing frame 2 and the support frame 3. At the same time, the compression spring 7 will push the connecting block 8 and the clamping plate 9 to move inward. The clamping plate 9 squeezes and clamps the culvert body 1 through the anti-slip rubber 10. When the impact force is transmitted to the culvert body 1 through the fixing frame 2 and the support frame 3, the compression spring 7 will absorb the impact force. Afterward, when the compression spring 7 rebounds, the damping rubber 11 will absorb the vibration generated by the rebound of the compression spring 7, thereby greatly reducing the impact force transmitted to the culvert body 1 and preventing the culvert body 1 from being damaged by the impact.

[0029] In summary, this in-situ protection structure for high-voltage power culverts absorbs the impact force transmitted to the culvert body 1 by setting up a compression spring 7 and a damping rubber 11, and uses the damping rubber 11 to absorb the vibration generated by the rebound of the compression spring 7, thereby protecting the culvert body 1 and preventing damage to the culvert body 1 due to impact, thus improving the practicality of the in-situ protection structure for high-voltage power culverts.
