[0036] Traditional waterproof sealing components used for the outlet of integrated utility tunnels are usually fixed with a lot of bolts, which makes the installation and disassembly cumbersome. They also lack a dehumidification mechanism, which can easily lead to corrosion of internal components, causing many inconveniences for subsequent maintenance and upkeep.

[0037] To address the problem that traditional waterproof sealing components are prone to corrosion of internal components, this invention provides a waterproof sealing component for the outlet of a utility tunnel. This component uses a clamping mechanism to replace the fixing bolts, simplifying the assembly and disassembly process and effectively preventing corrosion of internal components.

[0038] To describe in detail the structure of the waterproof sealing assembly for the outlet of a utility tunnel according to the present invention, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0039] Example 1

[0040] Figures 1-4 The cross-sectional view of a waterproof sealing assembly for a utility tunnel outlet according to Embodiment 1 of the present invention, along with some of its components and assembly structure, are shown. Specifically, Figure 1 This is a front view of a waterproof sealing assembly for the outlet of a utility tunnel according to Embodiment 1 of the present invention. Figure 2 This is a side sectional view of the sealing block. Figure 3 This is a schematic diagram of the second sectional view of the sealing block from the front view. Figure 4 This is a schematic diagram of the three-dimensional assembly structure of the sealing clamp, the first slider, and the rack.

[0041] like Figures 1-4 As shown in the figure, the waterproof sealing assembly for the outlet of the integrated utility tunnel in this embodiment mainly includes a conduit 2 fixedly installed on the wall 1 of the integrated utility tunnel, the conduit 2 penetrating the wall 1 of the integrated utility tunnel; wherein, a sealing block 3 is fixedly connected (e.g., by welding, or by other feasible fixing methods) to one end of the conduit 2, and a conduit hole 5 is provided through the sealing block 3, the conduit hole 5 penetrating the first rectangular cavity 4 and communicating with the conduit 2; the first rectangular cavity 4 is provided on the sealing block 3, and a clamping mechanism for clamping and fixing the conduit 2 is provided in the first rectangular cavity 4.

[0042] Specifically, the clamping mechanism includes two sealing clamps 6 that are slidably installed in the first rectangular chamber 4. Each of the two sealing clamps 6 is provided with a semi-circular wire-clamping groove 7 on the side where the two sealing clamps 6 are close to each other. The two semi-circular wire-clamping grooves 7 are adapted to form a clamping and fixing space for the wire tube 2.

[0043] Furthermore, a linkage clamping component is provided between the two sealing clamps 6. When the sealing clamp connected to the lead screw 9 moves to press upward to clamp the fixed space or to release downward to clamp the fixed space, the corresponding linkage sealing clamp simultaneously moves to press downward to clamp the fixed space or to release upward to clamp the fixed space.

[0044] Specifically, as an example, the linkage clamping component has a threaded through hole 8 penetrating the bottom inner wall of the first rectangular chamber 4, and a lead screw 9 threaded through the threaded through hole 8. The top end of the lead screw 9 is rotatably connected to the bottom of the sealing clamp 6 located below. Rectangular sliding grooves 10 are provided on both sides of the inner wall of the first rectangular chamber 4. Two first sliders 11 are slidably installed in the rectangular sliding grooves 10. The two first sliders 11 are respectively welded to the corresponding sealing clamps 6. Two racks 12 are slidably installed in the rectangular sliding grooves 10. One end of the rack 12 is welded to the corresponding first slider 11. A gear 13 is rotatably installed in the rectangular sliding grooves 10. The gear 13 is located between the two corresponding racks 12, and the gear 13 meshes with the rack 12.

[0045] By rotating the end of the lead screw 9 in the forward direction, the sealing clamp 6 connected to the lead screw 9 is lifted, and the two sealing clamps 6 are brought closer together by the linkage clamping mechanism between them, thereby clamping and fixing the wire guide tube 2 in the two semi-circular wire-clamping grooves 7. Conversely, by rotating the end of the lead screw 9 in the reverse direction, the sealing clamp 6 connected to the lead screw 9 is pulled down, and the two sealing clamps 6 are separated by the linkage clamping mechanism between them, thereby releasing the wire guide tube 2 from the two semi-circular wire-clamping grooves 7.

[0046] The aforementioned clamping mechanism effectively avoids the use of numerous bolts, making assembly and disassembly simple and convenient, and greatly facilitating subsequent maintenance work.

[0047] Example 2

[0048] like Figure 1 and Figure 6 As shown in the figure, as a further optimization of the above embodiment one, a drying mechanism is also provided at the end of the conduit away from the sealing block 3 to keep the inside of the sealing assembly dry.

[0049] Specifically, such as Figure 6As shown, the drying mechanism includes an annular connector 14 fixedly (e.g., by welding, or by other feasible fixing methods) at the end of the conduit 2 away from the sealing block 3. The annular connector 14 communicates with the conduit 2. Through grooves 15 are formed on the bottom inner walls of the conduit 2 and the annular connector 14, and a slide bar 16 is slidably installed within the through groove 15. A drying core 17 is fixedly installed on the top of the slide bar 16. The drying core 17 is used to keep the inside of the sealing assembly dry.

[0050] A movable block 18 is provided on the side of the annular connector 14 away from the sealing block 3. The movable block 18 is fixedly connected to the slide bar 16 (e.g., by welding, or by other feasible fixing methods). A second rectangular chamber 22 is formed on the movable block 18, and a first rectangular through hole 23 is formed on the inner wall of the second rectangular chamber 22 near the sealing block 3. A rectangular groove 19 is formed on the annular connector 14 at a position corresponding to the first rectangular through hole 23, and the first rectangular through hole 23 communicates with the rectangular groove 19.

[0051] Furthermore, slots 20 are provided on the top and bottom inner walls of the rectangular groove 19. A rod 21 is slidably installed in the slot 20. Two second sliders 25 are slidably installed in the second rectangular chamber 22. A first slide rod 24 is welded to the end of the second slider 25 near the sealing block 3. The first slide rod 24 slides through the first rectangular through hole 23 and extends into the rectangular groove 19. The rod 21 is welded and fixed to the corresponding first slide rod 24. A spring 26 is slidably installed between the two second sliders 25. The two ends of the spring 26 abut against the corresponding second sliders 25. A second rectangular through hole 27 is provided on the inner wall of the second rectangular chamber 22 away from the sealing block 3. Two second slide rods 28 slide through the second rectangular through hole 27. The second slide rods 28 engage with the corresponding second sliders 25.

[0052] The aforementioned drying mechanism effectively ensures the dryness of the internal environment of the sealing components, thereby preventing corrosion and leakage, and greatly facilitating subsequent maintenance.

[0053] Example 3

[0054] like Figure 5 As shown, as a further optimization of the above embodiments, the waterproof sealing assembly for the outlet of the integrated utility tunnel provided in this third embodiment also includes a first limiting mechanism.

[0055] Specifically, as an example, the aforementioned first limiting mechanism includes a first circular groove (not shown in the figure) and a rotating shaft (not shown in the figure) limited within the first circular groove. The first circular groove is formed on the inner wall of the rectangular slide 10 on the side away from the sealing clamp 6. A rotating shaft is rotatably mounted within the first circular groove, and one end of the rotating shaft extends outside the first circular groove and is welded and fixed to the corresponding gear 13.

[0056] By setting the first circular groove and the rotating shaft, the rotation amplitude of the gear can be limited without affecting the normal rotation of the gear, so that its rotation stroke is limited to the stroke of the two racks 12 cooperating with each other, thereby controlling the size of the clamping space of the two semi-circular wire clamping grooves 7 within a certain range and ensuring the stability of the linkage clamping component.

[0057] Example 4

[0058] like Figure 5 As shown, as a further optimization of the above embodiments, the waterproof sealing assembly for the outlet of the integrated utility tunnel provided in this embodiment four also includes a second limiting mechanism for limiting the sliding trajectory of the first slider 11 to prevent the first slider 11 from shaking during the sliding process.

[0059] Specifically, as an example, the second limiting mechanism includes two limiting grooves (not shown in the figure) opened on the inner wall of the rectangular slide groove 10 away from the sealing clamp 6, and a limiting block (not shown in the figure) is slidably installed in the limiting groove, and the limiting block is welded and fixed to the corresponding first slider 11.

[0060] Example 5

[0061] like Figure 2 As shown, as a further optimization of the above embodiments, the waterproof sealing assembly for the outlet of the integrated utility tunnel provided in this fifth embodiment also includes a water-stopping component to prevent water from entering the first rectangular chamber.

[0062] Specifically, as an example, a rubber sealing sleeve (not shown in the figure) is fixedly sleeved on the sealing clamp 6, and the rubber sealing sleeve is slidably connected to the inner wall of the first rectangular chamber 4.

[0063] Example 6

[0064] like Figure 2 As shown, as a further optimization of the above embodiments, the waterproof sealing assembly for the outlet of the integrated pipe gallery provided in this embodiment six also includes a sealing ring disposed in the threaded through hole 8, the purpose of which is also to prevent water from entering the first rectangular cavity from the threaded through hole 8.

[0065] Specifically, as an example, two sealing rings are fixedly installed in the threaded through hole 8. The sealing rings are rotatably sleeved on the lead screw 9. A round rod is welded to the top of the lead screw 9. A second round groove is opened at the bottom of the sealing clamp 6 located below. The round rod is rotatably installed in the second round groove.

[0066] In addition, to facilitate the operation of the lead screw 9, a handle can be welded and fixed to the bottom end of the lead screw 9. Construction workers can use the handle to more easily screw the lead screw 9 to install and remove conduits.

[0067] Example 7

[0068] like Figure 6 As shown, as a further optimization of the above embodiments, the waterproof sealing assembly for the outlet of the integrated utility tunnel provided in this embodiment seven also includes a third limiting mechanism, which is used to limit the sliding trajectory of the second slider 25 and the extension stroke of the spring, so as to prevent the second slider 25 from shaking during the sliding process.

[0069] Specifically, as an example, the third limiting mechanism includes a limiting hole that passes through the second slider 25 and a limiting rod that is fixedly disposed in the second rectangular chamber 22. The limiting rod slides through the two limiting holes, and the spring 26 is slidably sleeved on the limiting rod.

[0070] The waterproof sealing component for the outlet of a utility tunnel provided by this invention works on the following principle:

[0071] In use, first thread the cable through the annular connector 14, the conduit 2, and the through hole 5. Then, turn the handle. The handle drives the lead screw 9 to rotate and rise within the threaded through hole 8. Simultaneously, the lead screw 9 pushes the lower sealing clamp 6 to slide upward within the first rectangular chamber 4. The lower sealing clamp 6 also drives the two first sliders 11 to slide upward within their respective rectangular grooves 10. Simultaneously, the first sliders 11 drive the rack 12 to slide upward within the rectangular grooves 10, causing the gear 13 to rotate. The gear 13 then drives the other rack 12 to slide downward within the rectangular groove 10, causing the other first slider 11 to slide downward. This second first slider 11 then drives the upper sealing clamp 6 to slide downward within the first rectangular chamber 4 until the two sealing clamps 6 clamp the cable. This design effectively avoids the use of numerous bolts, simplifies assembly and disassembly, and greatly facilitates subsequent maintenance. When replacing the dryer core 17, first pull the two second slide rods 28, causing them to slide and approach each other within the second rectangular through hole 27. Simultaneously, the two second slide rods 28 drive the two second sliders 25 to slide and approach each other within the second rectangular chamber 22, compressing the spring 26. At the same time, the two second sliders 25 drive the two first slide rods 24 to slide and approach each other within the first rectangular through hole 23 and the rectangular groove 19, causing the two insert rods 21 to slide out of their corresponding slots 20. Then, pull the movable block 18, causing the first slide rods 24 and the insert rods 21 to slide out of the rectangular groove 19. Simultaneously, the slide bar 16 is driven to slide out of the through groove 15, allowing the dryer core 17 to be pulled out. The dryer core 17 can then be replaced. This setup effectively ensures the dryness of the environment inside the sealing assembly, effectively preventing rust and water leakage, and greatly facilitating subsequent maintenance.

[0072] Corresponding to the aforementioned waterproof sealing assembly for the outlet of a utility tunnel, this invention also provides a waterproof sealing method for the outlet of a utility tunnel, utilizing the waterproof sealing assembly as described above to achieve waterproof sealing of the outlet. The waterproof sealing method for the outlet of a utility tunnel in this embodiment includes the following steps:

[0073] S701: Pass the cable through the ring connector, conduit, and cable hole;

[0074] S702: Rotate the lead screw to rotate and rise within the threaded through hole, so that the two sealing plates clamp the cable; wherein, while the lead screw rises, the lead screw pushes the lower sealing plate to slide upward within the first rectangular cavity, and simultaneously the lower sealing plate drives the two first sliders to slide upward within their respective rectangular grooves, while the first sliders drive the rack to slide upward within the rectangular grooves, causing the gear to rotate, while the gear drives another rack to slide downward within the rectangular groove, causing the other first slider to slide downward, while the other first slider drives the upper sealing plate to slide downward within the first rectangular cavity, until the two sealing plates clamp the cable.

[0075] Furthermore, after the cable is clamped by two sealing plates, if it is necessary to replace the desiccant core in the conduit, the waterproof sealing method for the cable outlet of the integrated utility tunnel also includes:

[0076] S703: Pull the two second slide rods so that the two second slide rods slide and move closer to each other in the second rectangular through hole; wherein, during the process of the two second slide rods sliding and moving closer to each other in the second rectangular through hole, the two second slide rods drive the two second sliders to slide and move closer to each other in the second rectangular cavity, so that the spring is compressed, and at the same time the two second sliders drive the two first slide rods to slide and move closer to each other in the first rectangular through hole 23 and the rectangular groove, so that the two insert rods are driven to slide out of the corresponding slots respectively;

[0077] S704: Pull the movable block to cause the first slide rod and the insert rod to slide out of the rectangular groove, and at the same time the slide bar is driven to slide out of the through groove, thereby allowing the drying core to be extracted;

[0078] S705: Replace the drying element.

[0079] By utilizing the aforementioned waterproof sealing components and methods for the outlet of integrated utility tunnels, the clamping mechanisms installed at both ends of the conduit effectively avoid the use of excessive bolts, simplifying installation and disassembly. Simultaneously, they effectively ensure the dryness of the sealing components' interior, thereby preventing component corrosion and leakage, and greatly facilitating subsequent maintenance.

A method for waterproof sealing of the outlet of a utility tunnel, comprising using a waterproof sealing assembly as described in any one of claims 2-9 to waterproof seal the outlet of the utility tunnel, the method comprising: Pass the cable through the ring connector, conduit, and through hole; The lead screw is rotated and raised within the threaded through hole, causing the two sealing plates to clamp the cable. Simultaneously, as the lead screw rises, it pushes the lower sealing plate to slide upwards within the first rectangular cavity. At the same time, the lower sealing plate causes two first sliders to slide upwards within their respective rectangular grooves. These first sliders, in turn, cause a rack to slide upwards within the rectangular grooves, rotating the gear. This, in turn, causes another rack to slide downwards within the rectangular grooves, causing another first slider to slide downwards. This second first slider, in turn, causes the upper sealing plate to slide downwards within the first rectangular cavity, until the two sealing plates clamp the cable.
