Description

Technical Field

[0001] This utility model relates to the field of flood control equipment technology, specifically to a flood barrier for subway stations. Background Technology

[0002] With the intensification of global climate change and the increasing frequency of extreme weather events, the risk of urban flooding is constantly increasing. As underground enclosed spaces, subway stations are extremely vulnerable to damage during heavy rains or floods, which can cause not only huge economic losses but also threaten the safety of passengers and staff. To improve the ability of subway stations to cope with floods, flood barriers are widely used at potential water ingress points such as station entrances, ventilation openings, and connecting passages.

[0003] Existing flood control barriers typically consist of support bases on both sides and multiple layers of barriers. The support bases are fixed to the ground, while the barriers can be stacked according to the flood level to increase the flood control height. However, since the barriers are simply stacked without effective sealing measures, floodwater can easily seep through the gaps between the barriers or between the barriers and the ground, resulting in poor flood control performance. Therefore, we propose a flood control barrier for subway stations to solve the above problems. Utility Model Content

[0004] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0005] A flood control barrier for subway stations, comprising:

[0006] The support plate consists of two plates, and its sidewalls are constructed with rectangular channels at equal intervals, with a U-shaped notch constructed in the middle of one side of each rectangular channel;

[0007] A water baffle is evenly spaced between two support plates. The two ends of the water baffle slide through the inside of the rectangular channel. The water baffle has a hollow structure and an inlet / outlet channel is opened in the middle of its bottom.

[0008] A sealing mechanism is provided inside the water baffle to seal the gap between adjacent water baffles and between the water baffle and the ground;

[0009] A locking element is provided at the U-shaped notch to prevent the baffle plate from disengaging from the rectangular channel.

[0010] Furthermore, the sealing mechanism includes a sliding plate slidably disposed on the bottom side inside the baffle plate, a sealing gasket fixedly disposed on the bottom of the sliding plate, the sealing gasket being slidably inserted at the port of the inlet / outlet channel, and a driving component for driving the sliding plate to move up and down is disposed on the upper side inside the baffle plate.

[0011] Furthermore, the sealing gasket is a butyl rubber gasket.

[0012] Furthermore, a rectangular groove is constructed in the middle of the top of the baffle plate, and the size of the rectangular groove is adapted to the sealing gasket.

[0013] Furthermore, the driving component includes a rotating rod rotatably connected between the inner sidewalls of the baffle plate. The rotating rod has threads with opposite helical directions on both sides and is symmetrically threaded to a mounting block. A connecting plate is hinged to the bottom of the mounting block, and the end of the connecting plate away from the mounting block is hinged to the top of the slide plate.

[0014] Furthermore, one end of the rotating rod passes through the outer wall of the baffle plate and is connected to a knob.

[0015] Furthermore, the locking component includes connecting rods symmetrically fixed to the end side of the baffle plate, the connecting rods slidingly inserted into the interior of the U-shaped notch, and an annular elastic cord sleeved between the two connecting rods.

[0016] The beneficial effects of this utility model are as follows:

[0017] 1. This utility model achieves effective sealing between water-blocking plates and between the water-blocking plates and the ground through the design of the sealing mechanism. When the driving component (rotating rod) is turned by the knob, the symmetrical threads at both ends will drive the mounting blocks to move in opposite directions, and then drive the sliding plate to rise and fall through the connecting plate. When the sliding plate falls, the sealing gasket protrudes from the inlet and outlet channel and sticks tightly to the lower surface to close the gap, thereby blocking the water flow and greatly improving the flood control effect. The design of the locking component ensures the stability of the water-blocking plate under the impact of flood and prevents accidental movement or falling off. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0023] This application provides a flood control barrier for subway stations, mainly to solve the problem in existing technologies where the barriers are simply stacked without effective sealing measures, allowing floodwater to easily seep through gaps between the barriers or between the barriers and the ground, resulting in poor flood control performance. The following technical solution is provided, which will be discussed in conjunction with... Figures 1-3 Please provide a detailed explanation:

[0024] A flood control barrier for a subway station includes: two support plates 1, whose side walls are equally spaced rectangular channels 101, and a U-shaped opening 102 is formed in the middle of one side of the rectangular channel 101;

[0025] Water baffle 2 is evenly spaced between two support plates 1. The two ends of the water baffle 2 slide through the inside of the rectangular channel 101. The water baffle 2 has a hollow structure and an inlet / outlet channel is opened in the middle of its bottom.

[0026] A sealing mechanism 3 is installed inside the baffle plate 2 to seal the gap between adjacent baffle plates 2 and between the baffle plate 2 and the ground. The sealing mechanism 3 includes a sliding plate 301 that is slidably installed on the bottom side inside the baffle plate 2. A sealing gasket 302 is fixedly installed at the bottom of the sliding plate 301. The sealing gasket 302 is slidably inserted at the port of the inlet and outlet channel. A driving component is provided on the upper side inside the baffle plate 2 to drive the sliding plate 301 to move up and down. The driving component includes a rotating rod 303 that is rotatably connected between the inner side walls of the baffle plate 2. The two sides of the rotating rod 303 are constructed with threads in opposite directions and are symmetrically threaded to a mounting block 304. A connecting plate 305 is hinged to the bottom of the mounting block 304. The end of the connecting plate 305 away from the mounting block 304 is hinged to the top of the sliding plate 301.

[0027] Locking element 4 is located at the U-shaped opening 102 to prevent the water baffle 2 from disengaging from the rectangular channel 101.

[0028] The specific implementation process and principle of the flood control barriers in this subway station are explained below.

[0029] First, insert both ends of the baffle plate 2 into the rectangular channel 101 of the support plate 1. Ensure that the baffle plate 2 is stably installed between the two support plates 1, and use the locking piece 4 to fix the baffle plate 2.

[0030] Next, turn knob 306 to rotate rod 303. Since the threads on both sides of rod 303 are opposite, this will cause the two mounting blocks 304 to move towards or away from each other. Connecting plate 305, along with the movement of mounting blocks 304, pushes slide plate 301 up and down. When slide plate 301 moves downwards, the butyl rubber sealing gasket 302 at the bottom protrudes from the inlet / outlet channel and fits tightly against the lower baffle plate 2 or the ground. This effectively seals the gaps between the baffle plate 2 and the ground, as well as between adjacent baffle plates 2, preventing flood leakage.

[0031] Finally, after the floodwaters recede, turn knob 306 in the opposite direction to raise slide plate 301, causing sealing gasket 302 to retract into the inlet / outlet channel. Release locking piece 4 to easily remove water baffle 2.

[0032] The device, through the design of the sealing mechanism 3, achieves effective sealing between the water-blocking plates 2 and between the water-blocking plates 2 and the ground. When the driving component (rotating rod 303) is rotated by the knob 306, the symmetrical threads at both ends drive the mounting blocks 304 to move in opposite directions, thereby driving the sliding plate 301 to rise and fall through the connecting plate 305. When the sliding plate 301 descends, the sealing gasket 302 protrudes from the inlet and outlet channel, closely adhering to the lower surface to seal the gap, thereby blocking water flow and greatly improving the flood control effect. The design of the locking component 4 ensures the stability of the water-blocking plates 2 under the impact of floods, preventing accidental movement or detachment.

[0033] like Figure 1 As shown, in some embodiments, the sealing gasket 302 is a butyl rubber gasket. More specifically, butyl rubber maintains its elasticity over a wide temperature range, enabling it to adapt to the unevenness of the ground or the baffle 2, ensuring that the sealing gasket 302 fits tightly against the underlying surface. At the same time, butyl rubber has excellent gas and moisture barrier capabilities due to its molecular structure, which means that it can effectively prevent water from flowing through tiny gaps, providing a reliable waterproof seal.

[0034] like Figure 3 As shown, in some embodiments, a rectangular groove 201 is constructed in the middle of the top of the baffle plate 2. The rectangular groove 201 is adapted to the size of the sealing gasket 302. More specifically, when the sealing gasket 302 is inserted into the rectangular groove 201, it can ensure that the sealing gasket 302 will not shift under pressure, providing a tighter and more effective sealing effect.

[0035] like Figure 3 As shown, in some embodiments, one end of the rotating rod 303 passes through the outer wall of the baffle plate 2 and is connected to a knob 306. More specifically, the operator can easily rotate the rotating rod 303 through the knob 306. The knob 306 is set so that the operator can accurately control the degree of rotation of the rotating rod 303, thereby accurately adjusting the position of the slide plate 301 and the sealing gasket 302 to ensure the sealing effect.

[0036] like Figure 1As shown, in some embodiments, the locking member 4 includes connecting rods 401 symmetrically fixed to the end sides of the baffle plate 2. The connecting rods 401 slide through the inside of the U-shaped notch 102. An annular elastic cord 402 is sleeved between the two connecting rods 401. More specifically, by looping the annular elastic cord 402 around the connecting rods 401 on both sides, the baffle plate 2 can be tightly fixed to the support plate 1. The elastic cord has a certain elasticity, which can adapt to the small displacement of the baffle plate 2 while maintaining a firm lock.

[0037] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
