Description

Technical Field

[0001] This utility model relates to the field of flood control technology for subway stations, specifically to underground flood control barriers at subway station entrances and exits. Background Technology

[0002] Flood barriers used at subway entrances are an important flood control facility, mainly used to prevent floodwater from entering the subway station. When facing heavy rain or rising water levels in nearby water bodies, timely installation of flood barriers can prevent floodwater from entering the subway and protect the safety of underground facilities and passengers.

[0003] To meet the needs of convenience and rapid response, existing flood control barriers at subway entrances typically involve installing slots at the entrance. When needed, the barriers are moved from storage to the entrance and inserted into the slots to block the entrance and prevent water from flowing into the subway. When the barriers are no longer needed, they must be removed and moved to a designated storage location. The barriers are relatively large, making them inconvenient to move around within the subway station and taking up storage space. In the event of sudden heavy rain or other emergencies, taller barriers are used to prevent water levels from rising and flooding the subway. However, installing taller barriers can obstruct the passage of passengers entering and exiting the subway station, causing inconvenience. Utility Model Content

[0004] The purpose of this utility model is to provide an underground flood control barrier for subway station entrances and exits, which aims to solve the problem that the use of high barriers in the prior art can easily affect the passage of passengers entering the subway station.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a buried flood control barrier at the entrance of a subway station, including an entrance passage, a walking platform at the front end of the entrance passage, a flood control door frame installed at the upper end of the walking platform, an upward-facing groove at the upper end of the walking platform on one side of the flood control door frame, a flood control barrier hinged in the groove, a rectangular groove on the upper surface of the flood control barrier, a support plate hinged in the rectangular groove, a folding ladder hinged at the lower end of the flood control barrier, and sealing gaskets that cooperate with the flood control barrier on both sides of the flood control door frame.

[0006] Preferably, the folding ladder includes a connecting plate hinged to the bottom of the flood control baffle, an elastic band fixedly connected between the connecting plate and the flood control baffle, support rods hinged to both ends of the connecting plate, multiple sets of flipping pedals hinged between the two support rods, a synchronization rod hinged between the flipping pedals, and a tie rod connected to the synchronization rod hinged to the flood control baffle.

[0007] Preferably, the flood control baffle is provided with rotating rods symmetrically at both ends, and the inner wall of the groove is provided with a rotating groove that cooperates with the rotating rods.

[0008] Preferably, the lower ends of the two support rods are hinged with push-pull plates.

[0009] Preferably, two guide rods are symmetrically arranged in the groove along the moving direction of the push-pull plate, and the push-pull plate is slidably engaged with the guide rods.

[0010] Preferably, at least two support plates are provided, and the width of the second support plate is significantly greater than that of the first support plate.

[0011] Preferably, the walking platform further includes a first drive mechanism for driving the flood control baffle to flip.

[0012] Preferably, a waterproof chamber is installed on one side of the flood control gate frame on the walking platform, and the first drive mechanism is a first waterproof motor fixedly installed inside the waterproof chamber. The output shaft of the first waterproof motor extends into the rotating groove and is fixedly connected to one of the rotating rods.

[0013] Preferably, the walking platform also includes a second drive mechanism for controlling the opening and closing of the folding ladder.

[0014] Preferably, the walking platform has an equipment slot, the upper end of which is hinged with an inspection cover. The second drive mechanism is a second waterproof motor fixedly installed in the equipment slot. The output end of the second waterproof motor is connected to a lead screw, and the push-pull plate is threadedly engaged with the lead screw.

[0015] The beneficial effects of this utility model are:

[0016] 1. When this utility model is in use, if flood prevention is required, people can flip the flood barrier so that it is perpendicular to the groove and in contact with the sealing gasket on the flood barrier door frame to block the subway entrance and prevent floodwater from flowing into the subway station. There is no need to carry the flood barrier back and forth in the subway station, which improves efficiency. By setting a folding ladder on one side of the flood barrier, when the flood barrier is in a vertical state, people can unfold the folding ladder. The support plate hinged on the other side of the flood barrier will automatically flip to be perpendicular to the flood barrier under the action of gravity, making it easy for people to step on and cross the flood barrier, avoiding the flood barrier being set too high and affecting people's passage.

[0027] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0028] To facilitate understanding of this utility model, a more detailed description is provided below with reference to the accompanying drawings and specific embodiments. The accompanying drawings show preferred embodiments of this utility model. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0029] It should be noted that, unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention.

[0030] For example, the implementation of the underground flood control barrier at the entrance and exit of a subway station in this utility model. Figure 1-7 As shown, the underground flood control barrier 5 at the entrance of the subway station includes an entrance passage 1. A walking platform 3 is provided at the front end of the entrance passage 1. A flood control gate frame 2 is installed on the upper end of the walking platform 3. A groove 4 with an upward opening is provided on the upper end of the walking platform 3 on one side of the flood control gate frame 2. A flood control barrier 5 is hinged in the groove 4. A rectangular groove is opened on the upper surface of the flood control barrier 5. A support plate 18 is hinged in the rectangular groove. A folding ladder is hinged at the lower end of the flood control barrier 5. Sealing gaskets 15 that cooperate with the flood control barrier 5 are provided on both sides of the flood control gate frame 2.

[0031] In this embodiment, when flood prevention is needed, the flood barrier 5 can be flipped so that it is perpendicular to the groove 4 and contacts the sealing gasket 15 on the flood barrier frame 2 to block the subway entrance and prevent floodwater from flowing into the subway station. This eliminates the need to move the flood barrier 5 back and forth inside the subway station, improving efficiency. By setting a folding ladder on one side of the flood barrier 5, when the flood barrier 5 is in a vertical state, people can unfold the folding ladder. The support plate 18 hinged on the other side of the flood barrier 5 will automatically flip to be perpendicular to the flood barrier 5 under the action of gravity, making it easier for people to step on and cross the flood barrier 5, thus avoiding the flood barrier 5 being set too high and affecting people's passage.

[0032] like Figure 1 As shown, the folding ladder includes a connecting plate 7 hinged to the bottom of the flood control baffle 5. An elastic band 19 is fixedly connected between the connecting plate 7 and the flood control baffle 5. Support rods 8 are hinged to both ends of the connecting plate 7. Multiple sets of flipping steps 9 are hinged between the two support rods 8. Synchronizing rods 10 are hinged between the flipping steps 9. Tie rods 11 connected to the synchronous rods 10 are hinged on the flood control baffle 5.

[0033] In this embodiment, a groove is provided on the support rod 8, one end of which slides in cooperation with the connecting plate 7, so that the support rod 8 has a certain vertical movement space when it moves. An elastic band 19 is provided so that when the push-pull plate 13 moves, it drives the lower end of the support rod 8 to move, and at the same time pulls the connecting plate 7 to reset so that it fits against the flood control baffle 5.

[0034] like Figure 2 As shown, the flood control baffle 5 has symmetrical rotating rods at both ends, and the inner wall of the groove 4 has a rotating groove (not shown in the figure) that cooperates with the rotating rods.

[0035] In this embodiment, the first waterproof motor 16 is started, and its output shaft passes into the rotating groove to drive the rotating rod to rotate, thereby causing the flood control baffle 5 to flip until it is perpendicular to the groove 4 and the side of the flood control baffle 5 is in contact with the sealing gasket 15.

[0036] like Figure 2 As shown, the lower ends of the two support rods 8 are hinged to push-pull plates 13.

[0037] In this embodiment, the push-pull plate 13 and the lead screw 12 move back and forth to drive the support rod 8 to move. At the same time, when the support rod 8 is reset to the bottom of the flood control baffle 5, the push-pull plate 13 is also folded at the bottom of the support rod 8.

[0038] like Figure 3 As shown, two guide rods 14 are symmetrically arranged in the groove 4 along the moving direction of the push-pull plate 13, and the push-pull plate 13 is slidably engaged with the guide rods 14.

[0039] In this embodiment, the stability of the push-pull plate 13 is increased when it moves by setting the guide rod 14.

[0040] like Figure 1 As shown, at least two support plates 18 are provided, and the width of the second support plate 18 is significantly larger than that of the first support plate 18.

[0041] In this embodiment, the support plate 18 gradually widens to facilitate people stepping on it.

[0042] like Figure 3 As shown, the walking platform (3) also includes a first drive mechanism that drives the flood control baffle (5) to flip.

[0043] In this embodiment, the flood control baffle can also be automatically rotated by the first drive mechanism, saving manpower.

[0044] like Figure 4 As shown, a waterproof chamber 6 is installed on one side of the flood control gate frame 2 on the walking platform 3. The first drive component is a first waterproof motor 16 fixedly installed inside the waterproof chamber 6. The output shaft of the first waterproof motor 16 extends into the rotating groove and is fixedly connected to one of the rotating rods.

[0045] In this embodiment, the waterproof compartment 6 is detachably installed on one side of the walking platform 3 by bolts for easy maintenance, and a waterproof pad (not shown in the figure) is provided at the connection between the waterproof compartment 6 and the walking platform 3.

[0046] like Figure 3 As shown, the walking platform 3 also includes a second drive mechanism for controlling the opening and closing of the folding ladder.

[0047] In this embodiment, the opening and closing of the folding ladder can also be automatically controlled by setting a second drive mechanism, eliminating the need for manual opening and saving manpower.

[0048] like Figure 4 As shown, the walking platform 3 has an equipment slot, and an inspection cover is hinged to the upper end of the equipment slot. The second drive mechanism is a second waterproof motor 17 fixedly installed in the equipment slot. The output end of the second waterproof motor 17 is connected to a lead screw 12, and the push-pull plate 13 is threadedly engaged with the lead screw 12.

[0049] In this embodiment, the second waterproof motor 17 can be inspected by opening the inspection cover. A waterproof pad is provided at the connection between the inspection cover and the equipment slot to enhance the waterproof effect. When the second waterproof motor 17 is started, it can drive the lead screw 12 to rotate in both directions, which is used to drive the push-pull plate 13 to move back and forth.

[0050] Working principle: In use, the flood control baffle 5 is flipped until it is perpendicular to the groove 4 and the side of the flood control baffle 5 is in contact with the sealing gasket 15. At this time, the multiple support plates 18 on the flood control baffle 5 are flipped by gravity. The opening of the rectangular groove limits the flipping angle of the support plates 18, making them perpendicular to the flood control baffle 5 and in a horizontal state, which is convenient for people to step on. Then, people pull the push-pull plate 13 to move it closer to the second waterproof motor 17. When the push-pull plate 13 moves, it pulls the lower end of the support rod 8 to move. At this time, it is in contact with the upper end of the support rod 8. The hinged connecting plate 7 gradually flips from its position of being flush with the flood control baffle 5 to a horizontal position, eventually becoming perpendicular to the flood control baffle 5, serving as the uppermost step of the folding ladder. When the lower end of the support rod 8 moves, the tie rod 11 pulls the synchronous rod 10 downwards. The synchronous rod 10 pulls multiple sets of flipping steps 9 to flip along the support rod 8 until they are in a horizontal position. The straw is pulled closer to the synchronous rod 10 to support it, ensuring the stability of the flipping steps 9 and making them easy for people to step on. When people need to enter the subway station, they can step on the flipping steps. Plate 9 and support plate 18 pass over flood barrier 5 and enter the subway station. When flood barrier 5 is no longer needed, people push the push-pull plate 13 to move closer to flood barrier 5. When the push-pull plate 13 moves, it drives the lower end of support rod 8 to move. At the same time, elastic band 19 pulls connecting plate 7 to reset, so that it fits against flood barrier 5. When support rod 8 moves, tie rod 11 flips upward, pushing synchronous rod 10 to move upward, finally causing flipping pedal 9 to reset and become parallel to flood barrier 5. At this time, the flood barrier 5 is flipped again to gradually flip. Inside the recess 4, the support plate 18 automatically flips back into the rectangular groove due to inertia, avoiding obstruction of passage. In another embodiment, a first waterproof motor 16 is provided, whose output shaft drives the rotating rod to rotate, thereby causing the flood control baffle 5 to flip until it is perpendicular to the recess 4, thus automatically opening the flood control baffle 5. A second waterproof motor 17 is provided, whose output shaft drives the lead screw 12 to rotate, pulling the push-pull plate 13 to move closer to the second waterproof motor 17, so as to automatically unfold the folding ladder and save manpower.
