Description

Technical Field

[0001] This application relates to the field of municipal drainage, and in particular to a municipal road drainage structure. Background Technology

[0002] Rainwater well covers quickly drain rainwater through their own grid holes, thus preventing water accumulation on the road surface.

[0003] See Chinese utility patent CN205822254U, which discloses a manhole cover. The key technical features of the cover are: a bracket with a groove and a cover with a pull hole. The cover is snapped into the groove, and a retaining edge is fixed to the edge of the cover. The distance from the retaining edge to the bottom of the groove is not less than the distance from the top of the bracket to the bottom of the groove. A pull rod is slidably connected in the pull hole, and a locking block is fixed to both ends of the pull rod. The locking block cannot pass through the pull hole.

[0004] The above structure makes it inconvenient to remove and replace the entire manhole cover, which is quite inconvenient and needs to be improved. Utility Model Content

[0005] To facilitate the removal and replacement of manhole covers, this application provides a municipal road drainage structure.

[0006] This application provides a municipal road drainage structure, which adopts the following technical solution:

[0007] A municipal road drainage structure includes a road body, the road body having a drainage channel and an extension channel, the drainage channel communicating with the extension channel, the road body having a manhole cover body located in the drainage channel, the manhole cover body having an extension block embedded in the extension channel, the extension channel wall having a sliding block located at the end of the extension block away from the manhole cover body, the sliding block sliding on the extension channel wall, the sliding direction of the sliding block being vertical.

[0008] By adopting the above technical solution, a sliding block and an extension block are set up. When it is necessary to remove the manhole cover body, the sliding block is detached from the extension groove by sliding the sliding block. At this time, the extension groove leaves space, which makes it easy to tilt the manhole cover body by manually or with the help of tools, thereby facilitating the removal and replacement of the manhole cover body and making the removal and replacement operation more convenient.

[0009] Optionally, the sliding block is provided with a mounting groove, the bottom of the mounting groove is provided with a mounting spring, and the end of the mounting spring away from the bottom of the mounting groove is provided with a closing block. The closing block slides on the wall of the mounting groove, the sliding direction of the closing block is vertical, and the elastic force of the mounting spring causes the closing block to close the mounting groove.

[0010] By adopting the above technical solution, a sealing block and a mounting spring are set up. The elastic force of the mounting spring makes the end of the sliding block away from the bottom of the extension groove flush with the ground. When the manhole cover body needs to be removed, the sealing block is pressed towards the bottom of the extension groove to expose the mounting groove, thereby making it easier to contact the mounting groove and pull the sliding block for subsequent removal of the manhole cover body.

[0011] Optionally, the mounting groove wall is provided with a force groove, and the sealing block is used to cover the force groove. When the sealing block moves closer to the bottom of the mounting groove, the force groove is connected to the outside.

[0012] By adopting the above technical solution and setting the force groove, it is easy for the sealing block to contact the force groove and pull the sliding block after it moves, making the subsequent disassembly of the manhole cover body more convenient.

[0013] Optionally, the mounting groove wall is provided with a snap-fit ​​groove, the snap-fit ​​groove is provided with a snap-fit ​​element, the sealing block groove wall is provided with a connecting groove, the connecting groove is for the snap-fit ​​element to be embedded, and the snap-fit ​​element is used to restrict the movement of the sealing block.

[0014] By adopting the above technical solution, a snap-fit ​​component is set up to restrict the accidental movement of the enclosure block and reduce the possibility of the enclosure block moving due to pedestrian or vehicle traffic.

[0015] Optionally, the snap-fit ​​component includes a snap-fit ​​spring and a snap-fit ​​block. The snap-fit ​​spring is located at the bottom of the snap-fit ​​groove, and the snap-fit ​​block is located at the end of the snap-fit ​​spring away from the snap-fit ​​block. The snap-fit ​​block is used to embed into the connecting groove. The snap-fit ​​block has an abutting surface located at the end of the snap-fit ​​block away from the bottom of the mounting groove. The abutting surface extends in a direction close to the bottom of the snap-fit ​​groove away from the bottom of the mounting groove, and the abutting surface is used to abut against the bottom of the connecting groove.

[0016] By adopting the above technical solution and setting a contact surface, when the sealing block is subjected to a force toward the bottom of the locking groove, the locking block is subjected to a partial force toward the bottom of the locking groove due to the action of the contact surface. When the pressure on the sealing block further increases, the locking block moves toward the direction closer to the bottom of the locking groove. In this way, the situation of the sealing block moving due to accidents is reduced, making the overall use more stable.

[0017] Optionally, the extension block is provided with a fixing groove, which is located on the side of the extension block near the sliding block, and the opening of the fixing groove abuts against the side wall of the sliding block.

[0018] By adopting the above technical solution, a fixing groove is set up, which allows workers to use tools to exert force, thereby facilitating the pulling of the manhole cover body and enabling subsequent disassembly of the manhole cover body.

[0019] In summary, this application includes at least one of the following beneficial technical effects:

[0020] 1. Set up sliding blocks and extension blocks. When it is necessary to remove the manhole cover body, the sliding blocks are detached from the extension groove by sliding the sliding blocks. At this time, the extension groove leaves space, which makes it easy to pull the extension pipe manually or with the help of tools to tilt the manhole cover body, thereby facilitating the removal and replacement of the manhole cover body.

[0021] 2. Install snap-fit ​​connectors. These connectors are used to restrict the accidental movement of the enclosure block, reducing the likelihood of the enclosure block moving due to pedestrian or vehicular traffic.

[0022] 3. By setting an abutting surface, when the sealing block is subjected to a force toward the bottom of the locking groove, the snap-fit ​​block is subjected to a partial force toward the bottom of the locking groove due to the action of the abutting surface. When the pressure on the sealing block increases further, the snap-fit ​​block moves toward the bottom of the locking groove. In this way, the situation of the sealing block moving due to accidents is reduced, making the overall use more stable. Attached Figure Description

[0026] The present application will be further described in detail below with reference to the accompanying drawings.

[0027] This application discloses a municipal road drainage structure. (Refer to...) Figures 1 to 2 The system includes a road body 1, which has a drainage ditch 2 and an extension ditch 3 connected to the extension ditch 3. The road body 1 also includes a manhole cover body 4 located in the drainage ditch 2. The manhole cover body 4 has a drain hole 16 for draining liquid. The manhole cover body 4 also has an extension block 5 embedded in the extension ditch 3. The extension block 5 has a fixing groove located on the side of the extension block 5 furthest from the manhole cover body 4.

[0028] The extension groove 3 has a sliding block 7 on its wall. The sliding block 7 is located at the end of the extension block 5 away from the manhole cover body 4. The side wall of the sliding block 7 abuts against the opening of the fixed groove. The sliding block 7 slides on the wall of the extension groove 3. The sliding direction of the sliding block 7 is vertical.

[0029] The sliding block 7 is provided with a mounting groove 8, which is located at the end of the sliding block 7 away from the bottom of the extension groove 3. A mounting spring 9 is provided at the bottom of the mounting groove 8, and a closing block 10 is provided at the end of the mounting spring 9 away from the bottom of the mounting groove 8. The closing block 10 slides on the wall of the mounting groove 8, and the sliding direction of the closing block 10 is vertical. The elastic force of the mounting spring 9 causes the closing block 10 to close the mounting groove 8, and makes the end of the closing block 10 away from the bottom of the mounting groove 8 flush with the end of the sliding block 7 away from the bottom of the extension groove 3.

[0030] The mounting slot 8 has a snap-fit ​​slot 11 on its wall, and a snap-fit ​​component 12 is provided in the snap-fit ​​slot 11. The sealing block 10 has a connecting slot 13 on its wall, and the connecting slot 13 is for the snap-fit ​​component 12 to be embedded in. The snap-fit ​​component 12 is used to restrict the movement of the sealing block 10.

[0031] In this application, the snap-fit ​​component 12 includes a snap-fit ​​spring 121 and a snap-fit ​​block 122. The snap-fit ​​spring 121 is located at the bottom of the snap-fit ​​groove 11, and the snap-fit ​​block 122 is located at the end of the snap-fit ​​spring 121 away from the snap-fit ​​block 122. The snap-fit ​​block 122 is used to embed into the connecting groove 13. The snap-fit ​​block 122 is provided with an abutment surface 14, which is located at the end of the snap-fit ​​block 122 away from the bottom of the mounting groove 8. The abutment surface 14 extends in a direction close to the bottom of the snap-fit ​​groove 11 and away from the bottom of the mounting groove 8. The abutment surface 14 is used to abut the bottom of the connecting groove 13. In other embodiments, the wall of the connecting groove 13 may be provided with a connecting surface 6, which is parallel to the abutment surface 14. The connecting surface 6 is used to abut the abutment surface 14 to further reduce the possibility of the closing block 10 slipping due to accident.

[0032] The mounting groove 8 has a force-applying groove 15 on its wall, located on the side of the connecting groove 13 away from the bottom of the mounting groove 8. When the mounting spring 9 is in its normal state, the end of the closing block 10 away from the bottom of the mounting groove 8 is flush with the end of the sliding block 7 away from the bottom of the extension groove 3, at which point the closing block 10 covers the force-applying groove 15. When the closing block 10 moves toward the bottom of the mounting groove 8 and the locking block 122 disengages from the connecting groove 13, the force-applying groove 15 communicates with the outside.

[0033] The implementation principle of a municipal road drainage structure in this application embodiment is as follows: In actual use, after the manhole cover body 4 is installed, the snap-fit ​​block 122 is embedded in the connecting groove 13, and the end of the sealing block 10 away from the bottom of the installation groove 8 is flush with the end of the sliding block 7 away from the bottom of the extension groove 3.

[0034] When the manhole cover body 4 needs to be disassembled, press the sealing block 10 towards the wall of the mounting groove 8. At this time, the contact surface 14 causes the locking block 122 to be subjected to a component force towards the bottom of the locking groove 11. As the pressing force increases, the locking block 122 moves towards the bottom of the locking groove 11, and the sealing block 10 moves towards the bottom of the mounting groove 8. At this time, the force groove 15 is connected to the outside.

[0035] Then, by using the force groove 15 to pull the sliding block 7, the sliding block 7 is disengaged from the extension groove 3 and contacts the fixing groove to disassemble the manhole cover body 4.

[0036] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
