Description

Technical Field

[0001] This utility model relates to the field of tunnel engineering technology, specifically a flood control and water-blocking structure for the ventilation section of a tunnel opening. Background Technology

[0002] In recent years, tunnels built under lakes located within urban areas have often adopted the cofferdam-cut-and-cover method. The steps of this method are as follows: First, cofferdams (earth cofferdams or sheet pile cofferdams, etc.) are constructed along both sides of the tunnel, and the lake water within the cofferdams is pumped out. Second, the tunnel is constructed by excavating soil within the cofferdams, and then backfilled with soil. Finally, the water is drained, the cofferdams are removed, and the original lake landscape is restored. Tunnels constructed using this method generally have a rectangular multi-span box culvert structure.

[0003] For long or extra-long tunnels, solving the problem of ventilation over long distances is a challenge. The difficulty lies in the fact that, for construction sites with high aesthetic requirements, tall ventilation towers are generally not permitted. However, to ensure air quality within the tunnel, ventilation must be addressed. A better solution is to install open ventilation sections at regular intervals along the tunnel's length. For lakes with wide bodies of water, open ventilation sections can be incorporated into the tunnel by creating artificial islands within the lake.

[0004] However, the existing open ventilation sections of the tunnel still have certain defects. The flood control effect during use is not good. The existing ventilation section is not flood-proof. When floods come, the ventilation section is easily submerged, which can cause floodwater to enter the tunnel and affect the normal passage of the tunnel.

[0005] Based on this, a flood control and water-blocking structure for the ventilation section of a tunnel opening is provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0006] The purpose of this invention is to provide a flood control and water-blocking structure for the open ventilation section of a tunnel, so as to solve the problem of poor flood control effect of the tunnel ventilation section in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A flood control and water-blocking structure for an open ventilation section of a tunnel includes a waterproof seat, two sliding grooves on the inner sides of the waterproof seat, a support frame installed on the top of the waterproof seat, a sealing layer installed inside the support frame, a tunnel body installed at the bottom of the waterproof seat, and a ventilation opening section in the middle of the top of the tunnel body.

[0009] A drive assembly is installed inside the ventilation opening section;

[0010] The waterproof base is slidably connected to a baffle assembly, which includes a waterproof baffle. The waterproof baffle is slidably connected to the inside of the waterproof base. A connecting frame is installed on the bottom inner side of the waterproof baffle, and an installation plate is installed in the middle of the connecting frame.

[0011] A photovoltaic module is installed on the top of the waterproof baffle;

[0012] A rotating component is installed on the top of the connecting frame.

[0013] Based on the above technical solutions, this utility model also provides the following optional technical solutions:

[0015] In one alternative: the photovoltaic module includes a top plate mounted on top of a waterproof baffle, and four support frames are installed around the top of the top plate, with photovoltaic power generation equipment installed on the top and sides of the support frames.

[0016] In one alternative embodiment: the rotating assembly includes a support ring mounted on both sides of the top of the connecting frame, a drive motor mounted on one side of the support ring, and a rotating column mounted on the output end of the drive motor, the rotating column being rotatably connected inside the support ring.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0029] In one embodiment, such as Figure 1 - Figure 4 As shown, a flood control and water-blocking structure for an open ventilation section of a tunnel includes a waterproof seat 1. Two sliding grooves 11 are opened on both sides inside the waterproof seat 1. A support frame 12 is installed on the top of the waterproof seat 1. A sealing layer 13 is installed inside the support frame 12. A tunnel body 14 is installed at the bottom of the waterproof seat 1. A ventilation opening section 15 is opened in the middle of the top of the tunnel body 14.

[0030] A drive assembly is installed inside the ventilation opening section 15;

[0031] A baffle assembly is slidably connected inside the waterproof base 1. The baffle assembly includes a waterproof baffle 2, which is slidably connected inside the waterproof base 1. A connecting frame 21 is installed on the bottom inner side of the waterproof baffle 2, and an mounting plate 22 is installed in the middle of the connecting frame 21.

[0032] A photovoltaic module is installed on the top of the waterproof baffle 2;

[0033] A rotating assembly is installed on the top of the connecting frame 21.

[0034] In this embodiment, the waterproof baffle 2 is sealed by the sealing layer 13 inside the support frame 12, and the mounting plate 22 is supported by the bottom connecting frame 21 inside the waterproof baffle 2. The mounting plate 22 is slidably connected inside the sliding groove 11. The photovoltaic module absorbs sunlight to charge the battery 18, and the sealing component is rotated and closed by rotating the component.

[0035] In one embodiment, such as Figure 1 and Figure 2 As shown, the drive assembly includes a support plate 16, which is installed inside the ventilation opening section 15. An electric actuator 17 is installed inside the support plate 16, and a battery 18 is installed on one side of the bottom of the support plate 16. The electric actuator 17 is supported by the support plate 16, and the operation of the electric actuator 17 pushes the mounting plate 22 to move upward, thereby adjusting the height of the baffle assembly.

[0036] In one embodiment, such as Figure 1 and Figure 3 As shown, the photovoltaic module includes a top plate 23, which is installed on top of the waterproof baffle 2. Four support frames 24 are installed around the top of the top plate 23. Photovoltaic power generation equipment 25 is installed on the top and sides of the support frames 24. The support frames 24 support the photovoltaic power generation equipment 25, and the photovoltaic power generation equipment 25 absorbs sunlight to charge the storage battery 18.

[0037] In one embodiment, such as Figure 1 , Figure 3 and Figure 4 As shown, the rotating assembly includes a support ring 3, which is installed on both sides of the top of the connecting frame 21. A drive motor 31 is installed on one side of the support ring 3, and a rotating column 32 is installed at the output end of the drive motor 31. The rotating column 32 is rotatably connected to the inside of the support ring 3. By running the drive motor 31, the rotating column 32 is driven to rotate inside the support ring 3, thereby driving the sealing assembly to open or close.

[0038] In one embodiment, such as Figure 1 and Figure 4 As shown, a sealing assembly is installed on one side of the rotating column 32 to seal the ventilation opening section 15.

[0039] In one embodiment, such as Figure 1 and Figure 4As shown, the sealing assembly includes a waterproof cover plate 33, which is installed on one side of the rotating column 32. A sealing plate 34 is installed on one side of the waterproof cover plate 33, and a sealing strip 35 is installed on the other side of the waterproof cover plate 33. The bottom is sealed by the sealing plate 34, and the gap between the two waterproof cover plates 33 is sealed by the sealing strip 35.

[0040] In one embodiment, such as Figure 1 - Figure 4 As shown, the storage battery 18 is electrically connected to the electric push rod 17, the photovoltaic module and the rotating component, and supplies power to the device through the storage battery 18.

[0041] The above embodiment discloses a flood control and water-retaining structure for the ventilation section of a tunnel opening. The structure is supported by a support frame 24 and a photovoltaic power generation device 25. The photovoltaic power generation device 25 absorbs sunlight to generate electricity, which charges a storage battery 18, supplying power to the device. When the water level is high, the movement of the electric push rod 17 in the middle of the support plate 16 pushes the mounting plate 22 upward within the sliding groove 11, thereby causing the waterproof baffle 2 to move upward within the waterproof seat 1. The sealing layer 13 inside the support frame 12 seals the gaps of the waterproof baffle 2, thus increasing the flood control height of the device and preventing flooding. To address the issue of water entering the tunnel body 14 through the ventilation opening section 15, this device improves its flood control performance. When the flood level is too high, the operation of the drive motor 31 on one side of the support ring 3 drives the rotating column 32 to rotate inside the support ring 3, thereby causing the waterproof cover plate 33 to flip and close. The sealing plate 34 at the bottom of the waterproof cover plate 33 fits against the inner top of the waterproof seat 1, thus achieving a sealing effect. The sealing strip 35 on one side of the waterproof cover plate 33 fills and seals the gap between the two waterproof cover plates 33, preventing floodwater from entering the tunnel body 14 through the ventilation opening section 15 and improving the flood control and water-blocking effect of the structure.

[0042] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
