Description

Technical Field

[0001] This utility model belongs to the field of building safety protection technology, specifically relating to a two-way locking device for flood prevention baffles. Background Technology

[0002] In recent years, extreme weather events have become increasingly frequent, leading to a growing problem of urban flooding. Flooding not only inundates roads but also poses a significant challenge to urban infrastructure. Subways are fundamental to the normal operation of cities and the daily lives of citizens. Due to their underground location and enclosed nature, coupled with high passenger flow, a large influx of rainwater into stations in a short period can easily cause panic, leading to congestion, stampedes, and drowning accidents. Furthermore, water accumulation can damage station equipment, posing a threat to the safe operation of the subway. Therefore, current subway facilities have high safety protection requirements. Existing flood barriers have the following problems:

[0003] Firstly, it has poor safety: installation requires professional operation and has high requirements for the flatness and sealing of the wall surface, otherwise it is easy to leak.

[0004] Secondly, the installation is complicated: it requires pre-embedded bolts or drilling, which damages the original structure and is difficult to disassemble. It is not suitable for temporary scenarios. When the water pressure suddenly increases, the baffle may be overturned. The installation requires professional operation and has high requirements for the flatness and sealing of the wall surface, otherwise leakage is likely to occur.

[0005] Thirdly, the cost is relatively high: the weight requires multiple people to move it; if frequent disassembly and storage are required, it may increase labor costs and maintenance expenses.

[0006] Fourth, maintenance and storage are difficult: the sealing strips and metal parts of the baffle are prone to aging or corrosion, requiring regular inspection and replacement, resulting in high maintenance costs. When not in use, they need to be properly stored, and large baffles may take up a lot of space. Summary of the Invention

[0007] This utility model is proposed to solve the problems existing in the prior art, and its purpose is to provide a two-way locking device for flood prevention baffles.

[0008] The technical solution of this utility model is: a two-way locking device for flood prevention baffles, including a slide rail formed by angle steel, a flood prevention baffle module inserted in the slide rail, the flood prevention baffle module being a prefabricated assembly structure, and a fixing component for fixing the flood prevention baffle module being provided on the outside of the angle steel.

[0009] Furthermore, the floodproof baffle module includes an upper floodproof baffle module and a lower floodproof baffle module, and a sealing strip between the baffles is provided between the bottom of the first floodproof baffle module and the top of the second floodproof baffle module.

[0010] Furthermore, the slide rail formed by the angle steel enclosure and the flood control baffle module are in clearance fit.

[0011] Furthermore, the fixing component includes a first hexagonal bolt disposed outside the angle steel, the first hexagonal bolt entering the slide rail cavity, and the entry end of the first hexagonal bolt pressing against the first floodproof baffle module.

[0012] Furthermore, the first hexagonal bolt has a pressure bolt end at its entry end, which secures the first flood-proof baffle module.

[0013] Furthermore, a clamping groove is formed in the side wall of the first floodproof baffle module, the clamping groove corresponding to the end of the pressure bolt, and the width of the clamping groove is greater than the outer diameter of the end of the pressure bolt.

[0014] Furthermore, an inclined chamfer is formed between the bottom of the pressing groove and the lower groove wall, and the remaining width of the groove bottom is smaller than the outer diameter of the pressure bolt end, so that the inclined chamfer contacts the pressure bolt end.

[0015] Furthermore, a flood-proof baffle pad is provided between the angle steel and the side of the flood-proof baffle module away from the first hexagonal bolt.

[0016] Furthermore, the end of the pressure bolt is made of waterproof rubber, and an internal thread is formed in the end of the pressure bolt. The internal thread of the end of the pressure bolt and the external thread of the first hexagonal bolt are threaded together for fastening.

[0017] Furthermore, a threaded hole is formed in the angle steel, into which a first hexagonal bolt is screwed.

[0018] The beneficial effects of this utility model are as follows:

[0019] This utility model solves the problems of difficult installation, slow response, and difficult placement of existing flood control barriers. It modifies the existing method of fixing barriers at station entrances and exits, achieving the advantages of low cost, low manpower, and rapid response, while ensuring stability and sealing.

[0020] This utility model is highly efficient to install; one worker can complete the installation and fixation of both sides of the baffle with a hex wrench, which is quick and can respond rapidly to flood risks.

[0021] This utility model has low cost, simple structure and parts, utilizes existing devices, has low development and production costs, and is easy to disassemble, clean and maintain.

[0033] The present invention will now be described in detail with reference to the accompanying drawings and embodiments:

[0034] like Figures 1 to 3 As shown, a two-way locking device for flood prevention baffles includes a slide rail formed by angle steel 8, in which a flood prevention baffle module 6 is inserted. The flood prevention baffle module 6 is a prefabricated assembly structure, and a fixing component for fixing the flood prevention baffle module 6 is provided on the outside of the angle steel 8.

[0035] The flood prevention baffle module 6 includes a first flood prevention baffle module and a second flood prevention baffle module, and a baffle sealing strip 7 is provided between the bottom of the first flood prevention baffle module and the top of the second flood prevention baffle module.

[0036] The slide rail formed by the angle steel 8 and the floodproof baffle module 6 are fitted with a clearance.

[0037] The fixing component includes a first hexagonal bolt 1 disposed outside the angle steel 8. The first hexagonal bolt 1 enters the slide rail cavity, and the entry end of the first hexagonal bolt 1 abuts against the first floodproof baffle module.

[0038] The first hexagonal bolt 1 has a pressure bolt end 3 at its entry end, which fixes the first floodproof baffle module.

[0039] A clamping groove is formed in the side wall of the first floodproof baffle module. The clamping groove corresponds to the end 3 of the pressure bolt, and the width of the clamping groove is greater than the outer diameter of the end 3 of the pressure bolt.

[0040] An inclined chamfer is formed between the bottom of the pressing groove and the lower groove wall. The remaining width of the groove bottom is smaller than the outer diameter of the end of the pressure bolt 3, so that the inclined chamfer contacts the end of the pressure bolt 3.

[0041] A flood-proof baffle pad 5 is provided between the angle steel 8 and the side of the flood-proof baffle module 6 away from the first hexagonal bolt 1.

[0042] The pressure bolt end 3 is made of waterproof rubber, and an internal thread is formed in the pressure bolt end 3. The internal thread of the pressure bolt end 3 is threadedly fastened to the external thread of the first hexagonal bolt 1.

[0043] A threaded hole is formed in the angle steel 8, and the first hexagonal bolt 1 is screwed into it.

[0044] Specifically, the floodproof baffle module 6 includes a friction pad 4, which is made of waterproof rubber and is in contact with the end 3 of the pressure bolt.

[0045] Specifically, the friction pad 4 is in inclined contact with the end 3 of the pressure bolt, thereby generating lateral and vertical pressure on the flood control baffle module 6. The lateral pressure is offset by the contact of the flood control baffle pad 5, and the vertical pressure firmly fixes the first flood control baffle module to the second flood control baffle module.

[0046] Specifically, the first floodproof baffle module and the second floodproof baffle module are sealed with a double baffle sealing strip 7.

[0047] Specifically, the angle steel 8 is fixed by bolts, and a structural sealing strip and foam sealant are provided under the angle steel 8.

[0048] Specifically, the lower end of the second floodproof baffle module is provided with a bottom sealing strip 9.

[0049] Specifically, the lower ends of both the first and second floodproof baffle modules are assembled with concave arc-shaped sections.

[0050] Specifically, the second flood-proof baffle module has side fixing structures on both sides.

[0051] Specifically, the side fixing structure includes a second hexagonal bolt 10 disposed in the side plate. The second hexagonal bolt 10 is screwed into the side plate and has a rubber head made of waterproof rubber material at the screwing end. A groove is formed at the corresponding position of the second floodproof baffle module.

[0052] More specifically, the second floodproof baffle module has a back sealing strip 12 inside, and the second hexagonal bolt 10 has a second bolt cover plate 11 outside.

[0053] The working process of this utility model is as follows:

[0054] Under normal operating conditions without waterlogging:

[0055] The first bolt cover plate 2 is closed, the first hex bolt 1 is loosened, and the guide rail is retained.

[0056] Under conditions of waterlogging:

[0057] First, insert the flood-proof baffle module 6 into the slide rail from top to bottom;

[0058] Then, open the first bolt cover plate 2 and tighten the first hexagonal bolt 1;

[0059] Finally, the end 3 of the pressure bolt abuts against the floodproof baffle module 6, thereby fixing the floodproof baffle module 6.

[0060] The flooding situation has ended.

[0061] Loosen the first hex bolt 1 until it is detached from the flood protection baffle module 6, and remove the flood protection baffle module 6.

[0062] This utility model solves the problems of difficult installation, slow response, and difficult placement of existing flood control barriers. It modifies the existing method of fixing barriers at station entrances and exits, achieving the advantages of low cost, low manpower, and rapid response, while ensuring stability and sealing.

[0063] This utility model is highly efficient to install; one worker can complete the installation and fixation of both sides of the baffle with a hex wrench, which is quick and can respond rapidly to flood risks.

[0064] This utility model has low cost, simple structure and parts, utilizes existing devices, has low development and production costs, and is easy to disassemble, clean and maintain.

[0065] This invention features long lifespan and high reliability: weather-resistant materials and fatigue-resistant design extend the device's lifespan to over 10 years and reduce the failure rate by 80%.
