Description

Technical Field

[0001] This utility model relates to the field of underground utility tunnels, specifically a protective structure for underground utility tunnels. Background Technology

[0002] Underground utility tunnels are public tunnels in cities used to centrally lay various municipal pipelines to facilitate the transport and supply of gas and liquids. Due to external factors, cement debris may fall from the top of the underground utility tunnel. To prevent the falling cement debris from impacting the pipelines inside the underground utility tunnel, protective structures need to be installed inside the underground utility tunnel to protect the pipelines.

[0003] According to Chinese Patent No. CN221741357U, a waterproof monitoring structure for underground utility tunnels based on building information technology is disclosed. This utility model can effectively protect the pipelines, prevent damage to the pipelines caused by cement debris falling from the top of the underground utility tunnel building, and effectively improve the stability of the pipelines.

[0004] Regarding the aforementioned patent content, a protective plate is installed to shield and protect the pipeline, preventing cement debris falling from the top of the underground utility tunnel from impacting the pipeline. However, some cement debris accumulates on the top of the protective plate and is difficult to slide down and fall to the ground. Over time, a large amount of cement debris may accumulate on the top of the protective plate. Furthermore, when workers enter the underground utility tunnel for maintenance, if cement debris on the protective plate accidentally slides down, it may fall on the workers, causing injury and reducing safety during maintenance. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a protective structure for underground utility tunnels to solve the technical problem that cement debris piled on the protective plate is difficult to slide down.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an underground utility tunnel protection structure, comprising an underground utility tunnel body, wherein mounting grooves are provided on both sides of the underground utility tunnel body, mounting plates are inserted into the mounting grooves, and multiple locking bolts extending into the underground utility tunnel body are threadedly connected to the mounting plates. A sliding groove is provided on one side of the mounting plate, and a sliding plate, a first movable plate, and a second movable plate are respectively provided inside the sliding groove. Multiple return springs are installed above the inside of the sliding groove, and the bottom ends of the return springs are fixedly connected to the top of the first movable plate. A fixing plate is installed below one side of the mounting plate by fastening bolts, and a motor is installed on the fixing plate. The output end of the motor is connected to a drive shaft, and a cam is installed on the outer wall of the drive shaft.

[0007] By adopting the above technical solution, when it is necessary to shake off the cement debris piled on top of the protective plate, the staff can start the motor. The motor can drive the drive shaft to rotate, which in turn drives the cam to rotate.

[0008] Furthermore, multiple threaded holes are provided on both sides of the interior of the underground utility tunnel, the mounting groove is connected to the threaded holes, and one end of the locking bolt extends into the interior of the threaded holes.

[0009] By adopting the above technical solution, the mounting plate can be locked and fixed after the locking bolt is screwed into the corresponding threaded hole, preventing the mounting plate from falling off.

[0010] Furthermore, multiple dampers and shock-absorbing springs are installed inside the lower part of the slide, and the tops of the dampers and shock-absorbing springs are fixedly connected to the bottom of the second movable plate.

[0011] By adopting the above technical solution, when the second movable plate moves down, it will squeeze the damper and the shock-absorbing spring. The damper will be compressed by force and the shock-absorbing spring will be compressed, thereby playing a shock-absorbing and buffering role.

[0012] Furthermore, a protective plate is installed on one side of the skateboard.

[0013] By adopting the above technical solution, the protective plate can shield and protect the pipe below, preventing falling cement debris from directly falling onto the pipe.

[0014] Furthermore, the protective plate is located directly above the cam.

[0015] By adopting the above technical solution, when the cam rotates, it will push the protective plate upward, and then drive the slide plate upward.

[0016] Furthermore, support seats are installed on both sides of the interior of the underground utility tunnel, and a placement groove is provided on the top of the support seats. A support frame is fixed between the support seats and the underground utility tunnel.

[0017] By adopting the above technical solution, the design of the support base and placement groove facilitates the placement of pipes.

[0018] Furthermore, the bottom of the skateboard is in contact with the top of the second movable board, and the top of the skateboard is in contact with the bottom of the first movable board.

[0019] By adopting the above technical solution, when the skateboard moves down, it will push the second movable board down, and when the skateboard moves up, it will push the first movable board up.

[0020] Furthermore, the protective plate is slidably connected to the slide groove via a sliding plate, and both the first movable plate and the second movable plate are slidably connected to the slide groove.

[0021] By adopting the above technical solution, when the protective plate moves down, it will drive the sliding plate down, while the first movable plate and the second movable plate can slide inside the slide groove.

[0022] Furthermore, the mounting plate is detachably connected to the underground utility tunnel body via locking bolts.

[0023] By adopting the above technical solution, the mounting plate can be disassembled and assembled by tightening the bolts.

[0024] In summary, the present invention has the following main advantages:

[0025] 1. This utility model, by incorporating a motor, drive shaft, cam, first movable plate, and return spring, allows for the removal of cement debris accumulated on the top of a protective plate when necessary. The motor drives the drive shaft to rotate, which in turn rotates the cam. When the cam contacts the protective plate, it lifts the plate. This upward movement of the protective plate causes the sliding plate to move upward, which in turn pushes the first movable plate upward. The first movable plate then compresses the return spring. As the cam continues to rotate, it no longer contacts the protective plate, causing the return spring to stretch and push the first movable plate downward, along with the sliding plate and the protective plate. This repeated motion vibrates the protective plate, dislodging the cement debris accumulated on its top and preventing a large amount of cement debris from accumulating on the plate. This avoids the cement debris from suddenly falling onto workers during pipeline maintenance in underground utility tunnels, thus improving the safety of maintenance work.

[0026] 2. This utility model has a sliding groove, which can guide the first movable plate to improve the stability of the first movable plate when it moves. Attached Figure Description

[0035] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0036] The embodiments of this utility model will be described below based on its overall structure.

[0037] Example 1:

[0038] An underground utility tunnel protection structure, such as Figures 1-7 As shown, the underground utility tunnel includes a main body 1. Installation grooves 5 are provided on both sides of the main body 1. Installation plates 7 are inserted into the installation grooves 5, and multiple locking bolts 6 extending into the main body 1 are threaded onto the installation plates 7. Multiple threaded holes are also provided on both sides of the main body 1. The installation grooves 5 communicate with the threaded holes. One end of each locking bolt 6 extends into the threaded hole. When the locking bolt 6 is screwed into the corresponding threaded hole, the installation plate 7 can be locked and fixed to prevent it from falling off. A sliding groove 9 is provided on one side of the installation plate 7, and a sliding plate 10, a first movable plate 13, and a second movable plate 16 are respectively installed inside the sliding groove 9. Multiple return springs 12 are installed above the interior of the sliding groove 9, and the bottom end of each return spring 12 is fixedly connected to the top of the first movable plate 13.

[0039] See Figures 1-6 The bottom of the slide plate 10 is in contact with the top of the second movable plate 16, and the top of the slide plate 10 is in contact with the bottom of the first movable plate 13. When the slide plate 10 moves down, it will push the second movable plate 16 down. When the slide plate 10 moves up, it will push the first movable plate 13 up. The protective plate 11 is slidably connected to the slide groove 9 through the slide plate 10. The first movable plate 13 and the second movable plate 16 are both slidably connected to the slide groove 9. When the protective plate 11 moves down, it will drive the slide plate 10 down. The first movable plate 13 and the second movable plate 16 can slide inside the slide groove 9. The mounting plate 7 is detachably connected to the underground pipe gallery body 1 through the locking bolt 6. The mounting plate 7 can be disassembled and assembled through the locking bolt 6.

[0040] Specifically, a fixing plate 17 is installed on one side of the mounting plate 7 via fastening bolts, and a motor 19 is installed on the fixing plate 17. The output end of the motor 19 is connected to a drive shaft 8, and a cam 18 is installed on the outer wall of the drive shaft 8. When it is necessary to shake off the cement debris accumulated on the top of the protective plate 11, the staff can start the motor 19. The operation of the motor 19 can drive the drive shaft 8 to rotate, which in turn drives the cam 18 to rotate. A protective plate 11 is installed on one side of the sliding plate 10. The protective plate 11 can shield and protect the pipes below, preventing the falling cement debris from falling directly onto the pipes. The protective plate 11 is located directly above the cam 18. When the cam 18 rotates, it will push the protective plate 11 upward, which in turn drives the sliding plate 10 upward. Support seats 2 are installed on both sides of the interior of the underground pipe gallery body 1, and a placement groove 3 is opened on the top of the support seat 2. A support frame 4 is fixed between the support seat 2 and the underground pipe gallery body 1. The setting of the support seat 2 and the placement groove 3 facilitates the placement of pipes.

[0041] Example 2:

[0042] Based on the above embodiment 1, when cement debris falls onto the protective plate 11, the protective plate 11 will be subjected to impact force and vibrate. In order to improve the protective effect of the protective plate 11, it is necessary to buffer the impact force. Therefore, the following structure will be set.

[0043] See Figures 2-6 Multiple dampers 14 and shock-absorbing springs 15 are installed inside the lower part of the slide 9. The tops of the dampers 14 and shock-absorbing springs 15 are fixedly connected to the bottom of the second movable plate 16. When the second movable plate 16 moves down, it will squeeze the dampers 14 and shock-absorbing springs 15. The dampers 14 are compressed by force and the shock-absorbing springs 15 are compressed by force, thus playing a shock-absorbing and buffering role.

[0044] The working principle of this utility model is as follows: First, the support base 2 and the placement groove 3 are designed to facilitate the placement of pipes. When cement debris falls from the top of the underground pipe gallery body 1, the cement debris will fall onto the protective plate 11, thereby preventing the debris from falling directly onto the pipe and impacting it, thus improving the protection effect on the pipe. After being impacted by the cement debris, the protective plate 11 will move down and drive the sliding plate 10 to move down. The sliding plate 10 will then push the second movable plate 16 down. When the second movable plate 16 moves down, it will squeeze the damper 14 and the shock-absorbing spring 15. The damper 14 is compressed by force and the shock-absorbing spring 15 is compressed by force, thus playing a shock-absorbing and buffering role.

[0045] Because some cement debris will accumulate on the protective plate 11, and to prevent workers from suddenly falling on them while they are inspecting pipes in the underground utility tunnel, the cement debris on the protective plate 11 needs to be shaken off first. Therefore, before inspecting the pipes, workers can start the motor 19. The motor 19 drives the drive shaft 8 to rotate, which in turn drives the cam 18 to rotate. After the cam 18 rotates and contacts the protective plate 11, it can lift the protective plate 11. The upward movement of the protective plate 11 will cause the sliding plate 10 to move upward. Plate 10 pushes the first movable plate 13 upward, and the first movable plate 13 squeezes the return spring 12, causing the return spring 12 to be compressed. As the cam 18 continues to rotate, the cam 18 no longer contacts the protective plate 11. At this time, the return spring 12 is stretched and pushes the first movable plate 13 downward, and pushes the slide plate 10 and the protective plate 11 downward. This repetition can make the protective plate 11 vibrate up and down, so as to shake off the cement debris accumulated on the top of the protective plate 11 and prevent a large amount of cement debris from accumulating on the protective plate 11.
