[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please refer to the following: Figure 1 , Figure 2 , Figure 3 and Figure 4 ,in Figure 1 A schematic diagram of the municipal pipeline buried pipe structure provided by this utility model; Figure 2 This is a top view of the connection between the two cover plates of this utility model; Figure 3 This is a side view of the cover plate structure of this utility model; Figure 4 This is a perspective view of the cover plate structure of this utility model. A municipal pipeline buried pipe structure includes a pipe 2 disposed inside a foundation trench 1. A limiting block 3 is fixed inside the foundation trench 1, overlapping with the pipe 2. A cover plate 4 is provided on the top of the foundation trench 1. A chamber 401 is formed inside the cover plate 4, and a gear 402 is disposed within the chamber 401. A rack 403 meshes with the gear 402 on its outer side. Both ends of the rack 403 are respectively inserted into slots 404 and insertion holes 405 in the cover plate 4. A fixing block 406 is fixed inside the insertion hole 405 and located at one end of the rack 403. One end of the fixing block 406 extends out of the insertion hole 405 and is inserted into another slot 404. Inside the fixing groove 407 of the cover plate 4, a rotating rod 408 is fixed on the gear 402. A square groove 409 is opened inside the rotating rod 408. A square plate 410 is set inside the square groove 409. A square block 411 is fixed on the top of the square plate 410. The top of the square block 411 passes through the square hole 412 of the rotating rod 408 and is fixed to a turntable 413. The turntable 413 is set inside the circular groove 414 of the cover plate 4. A circular hole 415 is opened on the bottom wall of the circular groove 414 of the cover plate 4. The rotating rod 408 is rotatably connected inside the circular hole 415.

[0022] With the above technical solution, when it is necessary to inspect the pipe 2 in the base trench 1, pull the turntable 413 upward and rotate it. The turntable 413 drives the square block 411 to rotate in the square groove 409. When the square block 411 rotates, it drives the rotating rod 408 and the gear 402 to rotate. Through the meshing of the gear 402 and the rack 403, the rotation of the gear 402 causes the rack 403 to drive one end of the fixing block 406 to disengage from the fixing groove 407 and enter the insertion hole 405, so that the fixing block 406 is separated from the other cover plate 4. In this way, the cover plate 4 can be opened, which saves time and effort and makes it easier for workers to inspect the pipe 2.

[0023] Reference Figure 3 A spring 416 is fixed to the bottom wall of the square groove 409. The top of the spring 416 is fixedly connected to the bottom of the square plate 410. The upward movement of the square block 411 and the turntable 413 is limited by the elastic action of the spring 416, so that the turntable 413 and the square block 411 can only move under the condition of being pulled upward.

[0024] Reference Figure 3The cover plate 4 has a rotating groove 417 inside, and a rotating plate 418 is provided inside the rotating groove 417. The bottom end of the rotating rod 408 passes through the second circular hole 419 in the cover plate 4 and is fixed on the rotating plate 418. When the rotating rod 408 rotates, it drives the rotating plate 418 to rotate in the rotating groove 417. Through the cooperation between the rotating groove 417 and the rotating plate 418, the rotating rod 408 can move normally in the chamber 401, and the rotating rod 408 is limited to prevent it from moving upward.

[0025] Reference Figure 1 and Figure 2 The cover plate 4 has a groove 420 inside, and a slide rod 421 is fixed inside the groove 420. Two sliders 422 are slidably connected to the outside of the slide rod 421. The two sliders 422 extend out of the groove 420 and are fixed to the rack 403. When the rack 403 moves inside the cover plate 4, it drives the sliders 422 to slide on the slide rod 421. Through the cooperation of the slide rod 421 and the sliders 422, the movement of the rack 403 is limited, so that the rack 403 can move normally inside the cover plate 4.

[0026] Reference Figure 3 and Figure 4 The top of the turntable 413 has a groove 423, and a pull rod 424 is fixed to the bottom wall of the groove 423. The pull rod 424 facilitates the application of an upward pulling force to the turntable 413, thereby facilitating the pulling of the turntable 413 to the outside of the circular groove 414.

[0027] Reference Figure 1 and Figure 4 The top of the cover plate 4 has two grooves 425. A pull ring 426 is provided inside the groove 425. A movable shaft 427 is provided on the pull ring 426. The two ends of the movable shaft 427 are fixedly connected to the inner wall of the groove 425. By rotating the pull ring 426 inside the groove 425 and holding the pull ring 426, the cover plate 4 can be pulled upward, thereby removing the cover plate 4 from the base groove 1.

[0028] The implementation principle of a municipal pipeline buried pipe structure according to an embodiment of this utility model is as follows: pull the turntable 413 upward and rotate it. The turntable 413 drives the square block 411 to rotate in the square groove 409. When the square block 411 rotates, it drives the rotating rod 408 and the gear 402 to rotate. Through the meshing of the gear 402 and the rack 403, the rotation of the gear 402 causes the rack 403 to drive one end of the fixing block 406 to disengage from the fixing groove 407 and enter the insertion hole 405, so that the fixing block 406 is separated from another cover plate 4. In this way, the cover plate 4 can be opened, which saves time and effort and makes it easier for workers to inspect the pipeline 2.
