Description

Technical Field

[0001] This utility model relates to the field of floodproof door technology, and in particular to a floodproof door for subway entrances and exits. Background Technology

[0002] Floodgates are protective facilities used to prevent floods, tides, or backflow of water. They are usually installed at the entrances or connecting points of underground spaces and can be quickly closed during flood season or extreme weather conditions to form a waterproof barrier, preventing internal equipment from being flooded or people from being trapped. A type of floodgate for subway entrances and exits is a flood emergency device specifically designed for subway station entrances and exits. It is usually installed in subway station entrance and exit passages or at the connection with the ground. It can be quickly opened and closed during rainstorms, floods, or extreme weather conditions to form a temporary waterproof barrier, preventing external water from flowing back into the subway station and ensuring passenger safety, normal equipment operation, and protection of underground structures from water damage.

[0003] To address this, patent CN217897968U discloses a reinforced subway floodproof door structure. Relating to the field of floodproof door technology, the structure specifically includes a fixing plate. The back of the fixing plate has two floodproof door bodies. The front of each of the two floodproof door bodies has recessed holes, and a threaded ring is fixedly connected to the inner wall of each recessed hole. The front of the fixing plate has multiple first openings, each containing a fixing bolt. The rear end of each fixing bolt extends into the interior of each threaded ring, and the outer surface of the fixing bolt is threaded to the inner wall of the threaded ring. Reinforcing plates are provided on both the left and right sides of the floodproof door bodies, and slots are provided on the sides of the two floodproof door bodies that are far apart from each other. This reinforced subway floodproof door structure facilitates the disassembly of the two floodproof door bodies, reduces their volume and overall weight, improves the flexibility of transportation and handling, and achieves the effect of combining and installing them.

[0004] The aforementioned reinforced subway floodproof door structure achieves waterproofing through the closure of two floodproof door bodies during use. It relies solely on the adhesion of the door bodies for sealing, without any additional auxiliary sealing structure, thus failing to achieve double sealing and resulting in a low waterproofing effect. Utility Model Content

[0005] The purpose of this utility model is to provide a flood-proof door for subway entrances and exits, in order to solve the defect that the existing reinforced subway flood-proof door structure is not convenient for double sealing.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a flood-proof door for subway entrances and exits, including a base;

[0007] A wall is fixed to one side of the base, a doorway is provided inside the wall, and an opening and closing structure is installed on one side of the wall;

[0008] The base has a water-blocking structure at its top, which includes a placement groove at the top of the base. A water-blocking plate is installed inside the placement groove. A first sliding groove is provided at the middle of the bottom of the placement groove. A second sliding groove is provided on both sides of the first sliding groove. A first slider is installed inside the first sliding groove. A second slider is installed inside each of the second sliding grooves. An internal groove is provided on one side of the water-blocking plate. A hinge seat is fixed inside the internal groove. A movable rod is installed inside the hinge seat. A threaded rod is installed inside the first sliding groove. A second motor box is provided inside the base on one side of the placement groove. A second motor is installed inside the second motor box.

[0009] Preferably, the opening and closing structure includes a first door body installed on one side of the doorway, a second door body installed on one side of the first door body, a guide rail fixed on one side of the top of the wall, a first slide block installed on one side of the guide rail, a second slide block installed on the other side of the guide rail, connecting rods fixed on both sides of the bottom of the first and second slide blocks, a first support rod fixed on one side of the top of the first slide block, a first tooth fixed on the top of the first support rod, a second support rod fixed on one side of the top of the second slide block, a second tooth fixed on the bottom of the second support rod, a gear installed between the second support rod and the first tooth, a rotating shaft fixed on one end of the gear, a first motor fixed on one end of the rotating shaft on the other side of the wall, a sealing block fixed on one side of the first door body, a sealing groove provided on one side of the second door body, and a first motor box fixed on the other side of the top of the wall outside the first motor.

[0010] Preferably, the first door body and the second door body are symmetrically distributed on one side of the door opening, the first slide and the second slide are slidably connected to the guide rail, and the first slide and the second slide are symmetrically distributed on the outside of the guide rail.

[0011] With the above structure, the guide rail provides a fixed path for the movement of the first and second slide blocks during use, which restricts the direction of movement of the slide blocks and prevents the slide blocks from deviating, jamming or shaking when moving the door.

[0012] Preferably, the connecting rods are symmetrically distributed on both sides of the bottom end of the first slide and the second slide, and the bottom end of the connecting rods is fixedly connected to the top end of the first door and the second door, respectively.

[0013] With the above structure, when the first and second slides slide on the guide rail during use, the power can be directly transmitted to the door body through the connecting rod, ensuring that the movement of the door body and the slides is completely synchronized, avoiding the situation where the slides move while the door body lags behind, and ensuring the consistency of the door opening and closing action.

[0014] Preferably, both the first and second support rods are arranged in an "L" shape. The first teeth are evenly spaced at the top of the first support rod, and the second teeth are evenly spaced at the bottom of the second support rod. The first teeth and the second support rod are respectively meshed with the gear through the first teeth and the second teeth. The sealing block is fitted into the sealing groove, and the first door body and the second door body are sealed together through the sealing block and the sealing groove.

[0015] With the above structure, when the first motor drives the gear to rotate during use, the gear can simultaneously drive the first and second support rods to move in opposite directions in a straight line. This, in turn, through the first slide, the second slide, and the connecting rod, synchronously drives the first and second doors to move closer or further apart, ensuring that the opening and closing actions of the two doors are coordinated and consistent, avoiding jamming or misalignment. When the two doors are closed, the sealing block can be tightly embedded in the sealing groove, filling the gap between the two doors and effectively preventing water from seeping into the subway entrance from the door connection.

[0016] Preferably, the outer side of the baffle plate is fitted into the interior of the doorway, the placement groove is fitted into the baffle plate, rotating rods are fixed on both sides of one end of the baffle plate, and one end of the baffle plate is hinged to one side of the interior of the placement groove.

[0017] With the above structure, when the baffle is unfolded during use, it can fit tightly against the inner wall of the doorway, forming a surrounding seal that effectively prevents water from seeping in through the gaps between the baffle and the doorway. Combined with the door's seal, this creates a double waterproof barrier, significantly improving the overall waterproof performance of the flood-proof door.

[0018] Preferably, the second slide groove is symmetrically distributed on both sides of the first slide groove, the first slider is slidably connected to the first slide groove, the second slider is slidably connected to the second slide groove, the built-in grooves are evenly distributed on one side of the baffle plate, the built-in grooves correspond to the first slide groove and the second slide groove respectively, and the other end of the movable rod is hinged to the top of the first slider and the top of the second slider respectively.

[0019] With the above structure, during use, the two ends of the movable rod are hinged to the slider and the baffle respectively. When the slider slides in the groove, the movable rod can push or pull the baffle by changing the angle. With the symmetrically distributed slider and groove, the baffle is evenly stressed and has a stable movement trajectory during the unfolding and retraction process, without tilting or shaking.

[0020] Preferably, the first slider has an internal thread that matches the outer side of the threaded rod, the first slider and the threaded rod are threadedly connected, and one end of the threaded rod is fixedly connected to the output end of the second motor.

[0021] With the above structure, when the second motor starts and drives the threaded rod to rotate during use, the rotational motion can be converted into the linear motion of the first slider along the first groove, which can quickly drive the first slider to move, and then drive the baffle to unfold or retract through the movable rod, ensuring that the baffle unfolds to form a waterproof barrier.

[0022] The advantages of the flood-proof door for subway entrances and exits provided by this utility model are as follows:

[0023] With an opening and closing structure, the first motor drives the gear to rotate, and the gear meshes with the teeth to achieve rapid closing of the door. The first and second slides slide on the guide rail to ensure that the door moves smoothly and orderly, reducing shaking and jamming. When the first and second doors are closed, the sealing block and the sealing groove fit together to form a preliminary seal, which can quickly block the main path of water flow through the door opening.

[0024] By incorporating a water-blocking structure, a second motor drives a threaded rod to rotate, which in turn moves a slider via threaded transmission, causing the water-blocking plate to unfold. This allows the water-blocking plate to fit snugly against the bottom and sides of the door opening, forming a secondary seal with the door body. This double-seal design enhances the flood-proof performance of the flood-proof door, enabling the water-blocking plate to further impede water flow and provide reliable waterproofing for subway entrances and exits.

Connecting rods 406 are fixed to both sides of the bottom of the first slide 404 and the second slide 405. A first support rod 407 is fixed to one side of the top, and a first tooth 408 is fixed to the top of the first support rod 407. A second support rod 409 is fixed to one side of the top of the second slide block 405, and a second tooth 410 is fixed to the bottom of the second support rod 409. A gear 411 is installed between the second support rod 409 and the first tooth 408. A rotating shaft 412 is fixed to one end of the gear 411. A first motor 413 is fixed to one end of the rotating shaft 412 on the other side of the wall 2. A sealing block 414 is fixed to one side of the first door 401, and a sealing block 414 is provided on one side of the second door 402. The slot 415, the first motor box 416 is fixed on the other side of the top of the outer wall 2 of the first motor 413, the first door body 401 and the second door body 402 are symmetrically distributed on one side of the door opening 3, the first slide 404 and the second slide 405 are slidably connected to the guide rail 403 respectively, the first slide 404 and the second slide 405 are symmetrically distributed on the outside of the guide rail 403, the connecting rod 406 is symmetrically distributed on both sides of the bottom end of the first slide 404 and the second slide 405 respectively, and the bottom end of the connecting rod 406 is respectively connected to the first door body 401 and the second door body 402.

[0034] When the floodgate needs to be closed, the first motor 413 is started, driving the shaft 412 to rotate the gear 411. Since the gear 411 meshes with the first tooth 408 on the first support rod 407 and the second tooth 410 on the second support rod 409 respectively, the rotation of the gear 411 will drive the first support rod 407 and the second support rod 409 to move relative to each other. This will cause the first support rod 407 and the second support rod 409 to drive the first slide block 404 and the second slide block 405 to slide symmetrically on the guide rail 403. Through the connecting rod 406, the first door body 401 and the second door body 402 will move synchronously, so that the first door body 401 and the second door body 402 will approach each other and close. The sealing block 414 at its edge will fit into the sealing groove 415 to form a preliminary seal, blocking the water flow through the door opening 3.

[0035] Reference Figure 2 , Figure 3 and Figure 5 As shown, a water-blocking structure 5 is provided at the top of the base 1. The water-blocking structure 5 includes a placement groove 501 at the top of the base 1, a water-blocking plate 502 installed inside the placement groove 501, a first sliding groove 503 at the middle position of the bottom of the placement groove 501, and second sliding grooves 504 on both sides of the first sliding groove 503.
