Description

Technical Field

[0001] This utility model relates to the field of elevator technology, specifically to an elevator water-blocking device with water-blocking function and an elevator system with an elevator hall. Background Technology

[0002] Vertical elevators are commonly installed in underground passages, such as tunnels and subway stations. In my country, heavy rains are frequent during the summer, and inadequate urban drainage systems can lead to flooding. To prevent floodwaters from backflowing through elevator shafts during sudden floods and ultimately endangering the overall safety of the underground elevator system, effective protective measures have become an industry consensus.

[0003] Currently, the industry commonly adopts the solution of installing water-retaining barriers at the entrance of elevator hall doors. This solution requires reserving space for door jambs during the civil engineering phase, with the decoration company subsequently installing the barrier channels and finishing the stonework. The water-retaining barriers are usually stored in the lobby warehouse, and in the event of flooding, they must be manually moved to the lobby entrance for emergency installation. This existing solution has significant shortcomings: firstly, it heavily relies on close collaboration among multiple disciplines such as design, civil engineering, and decoration, significantly increasing the complexity and coordination difficulty of project management; secondly, relying on manual handling and installation during a disaster not only consumes manpower but also prolongs emergency response and handling time, delaying valuable flood prevention opportunities. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides an elevator water-blocking device with water-blocking function. The elevator water-blocking device can be installed in the elevator shaft of the elevator system and located on the sill of the elevator hall door. When flooding occurs and water needs to be blocked in the elevator hall, the elevator water-blocking device is transported to the floor of the hall door for water blocking.

[0005] This utility model discloses an elevator water-blocking device with water-blocking function, which includes a water-blocking gate, a servo motor, a reel, and a lifting steel wire. The servo motor and the reel are located above the sill of the elevator hall door. The lifting steel wire connects the water-blocking gate and the reel. The servo motor controls the reel and the lifting steel wire to rotate so that the water-blocking gate is transported to the sill of the elevator hall door for storage or to the floor of the elevator hall door for water blocking.

[0006] A further technical solution is: the water-retaining gate includes a gate fixing plate and a water-retaining gate plate, wherein the gate fixing plate is rotatably connected to the bottom of the water-retaining gate plate; the side of the gate fixing plate adjacent to the water-retaining gate plate is provided with a buckle, and when the water-retaining gate plate is flipped to be in close contact with the gate fixing plate, the buckle engages with the top of the water-retaining gate plate to fix the gate fixing plate to the water-retaining gate plate.

[0007] A further technical solution is that the gate fixing plate is connected to the bottom of the water-blocking gate plate by a hinge.

[0008] A further technical solution is that a rubber gasket is provided at the connection between the gate fixing pressure plate and the bottom of the water-blocking gate plate.

[0009] A further technical solution is: a lower flap is provided on the other side of the gate fixing plate, and the lower flap is detachably connected to the bottom of the gate fixing plate.

[0010] A further technical solution is to provide locking components at both ends of the gate fixing pressure plate.

[0011] A further technical solution is that the elevator water-blocking device with water-blocking function also includes two water-blocking gate guide columns, which are located inside the door frames on both sides of the elevator hall.

[0012] A further technical solution is: the guide column of the water-retaining gate is provided with a groove in the vertical direction, and the two ends of the water-retaining gate are respectively located in the grooves of the two guide columns of the water-retaining gate.

[0013] A further technical solution includes limit switches and a control box.

[0014] In addition, this utility model also provides an elevator system having an elevator hall, which includes an elevator car that can move up and down in the elevator shaft; an elevator door arranged at the hall station of the elevator hall for providing passengers to enter and exit the elevator car when the elevator car reaches the hall station; and an elevator water-blocking device with water-blocking function as in this utility model.

[0015] The beneficial effects of this utility model are: (1) Invisible and aesthetically pleasing design: The device adopts an ingenious integrated structure. In normal conditions, the water gate can be hidden at the top of the hall doorway without damaging the overall aesthetics of the building decoration, thus meeting the stringent requirements of modern public spaces for visual effects.

[0016] (2) Convenient and efficient manufacturing and installation: The installation process is greatly simplified.

[0025] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] This utility model discloses an elevator water-blocking device with a water-blocking function. The elevator water-blocking device is installed above the sill of the elevator hall in the elevator shaft of the elevator system. When it is necessary to block water at the floor level of the elevator hall, the water-blocking gate of the elevator water-blocking device is transported to the floor level of the hall to block water.

[0027] In one embodiment, such as Figures 1-6 As shown, the elevator water-blocking device with water-blocking function of this utility model includes a water-blocking gate 1, a servo motor 2, a reel 3, and lifting steel wires 4. The servo motor 2 and the reel 3 are located above the sill 21 of the elevator hall 20. For example, in one embodiment, both ends of the reel 3 are fixed to the wall of the elevator shaft housing the elevator system; in another embodiment, the reel 3 is fixed to the sill 21 of the hall door via support columns. The servo motor 2 is connected to the reel 3. In this embodiment, there are two lifting steel wires 4. One end of each lifting steel wire 4 is wound and fixed to the two ends of the reel 3, and the other ends of each lifting steel wire 4 are connected to both ends of the water-blocking gate 1. Figure 1 and Figure 2As shown. Servo motor 2 controls the rotation of the reel 3 and the lifting steel wire 4, causing the water-blocking gate 1 to rise or fall vertically relative to the reel 3, thus enabling the water-blocking gate 1 to move up and down between the upper sill 21 and the floor 22 of the elevator hall. When the water-blocking gate 1 rises to the upper sill 21 of the elevator hall, it can be fixed and stored. In this way, the water-blocking gate 1 can be hidden above the doorway of the elevator hall 20, without compromising the overall aesthetics of the building decoration. Furthermore, the water-blocking gate 1 will not be easily touched by unauthorized personnel and thus cannot be misappropriated, lost, or damaged by collisions. Therefore, it can be put into use promptly, conveniently, and intact when urgently needed, with high reliability and no safety risks. When the water-blocking gate 1 falls to the floor 22, it can prevent water at the floor 22 from flowing into the elevator shaft through the gap 23 between the elevator door and the floor, thus achieving the water-blocking function. In some embodiments, a limit switch 7 is also provided. When the water-blocking gate 1 moves upward to a set position, the limit switch 7 is triggered, and the servo motor 2 stops rotating, causing the water-blocking gate 1 to stop at the set position. In some embodiments, a servo motor with a built-in limit switch can be used. In this invention, the limit switch 7 and the servo motor 2 are controlled and linked by a control box 8. In some preferred embodiments, the control box 8 has a reserved interface with BAS, which can realize remote control of the raising and lowering of the water-blocking gate 1. In one specific embodiment, the control box model is AC136-01. In some embodiments, the limit switch and the control box are installed on the inner wall of the elevator shaft or on the sill of the lobby.

[0028] In one specific embodiment, the water-blocking gate 1 mainly consists of a gate fixing plate 11 and a water-blocking gate plate 12. The bottom of the gate fixing plate 11 is rotatably connected to the bottom of the water-blocking gate plate 12, allowing the water-blocking gate plate 12 to rotate relative to the gate fixing plate 11 at a certain angle, such as 90°. That is, the water-blocking gate plate 12 can rotate from a state tightly pressed against the gate fixing plate 11 (…). Figure 3 (As shown) Flipped to a position perpendicular to the gate fixing plate 11 ( Figure 5 (As shown). In some specific embodiments, the bottom of the gate fixing plate 11 and the bottom of the water-blocking gate plate 12 can be hinged or connected to ensure relative rotation between them. To ensure the water-blocking effect of the water-blocking gate, a sealing gasket, specifically a rubber gasket, is provided at the connection between the bottom of the gate fixing plate 11 and the bottom of the water-blocking gate plate 12. Figure 3 and Figure 4As shown, multiple clips 13 are fixed on the side of the gate fixing plate 11 adjacent to the water-retaining gate. The clips 13 include nuts, bolts 132, washers 133, and locking strips 131. After the bolts 132 are passed through the locking strips 131, washers 133, and gate fixing plate 11, the bolts 132 are locked with nuts on the other side of the gate fixing plate 11. When the water-retaining gate 12 is in close contact with the gate fixing plate 11, the nuts are loosened, and the locking strips 131 are rotated until one end of the locking strips 131 is perpendicular to the top of the water-retaining gate 12. Then, the nuts are tightened to lock the clips 13, thus fixing the gate fixing plate 11 to the water-retaining gate 12. When it is necessary to flip the water-retaining gate 12, the nuts are loosened again, and the locking strips 131 are rotated so that one end of the locking strips 131 leaves the top of the water-retaining gate 12, thus releasing the water-retaining gate 12. In other specific embodiments, the height of the gate fixing plate 11 (in the vertical state) is usually set between 20 cm and 50 cm, the height of the water-blocking gate 12 (in the vertical state) is set between 15 and 40 cm, and the width of the water-blocking gate 12 is the same as the distance between the two side door frames 24 of the elevator hall 20.

[0029] In this invention, two water-blocking gate guide posts 5 are also provided to accommodate two lifting steel wires 4 and the two ends of the water-blocking gate 1 connected to the other end of the lifting steel wires, so that the direction of the water-blocking gate 1 during the rising and falling process is relatively limited. In some embodiments, the two water-blocking gate guide posts 5 are respectively located inside the door frames 24 on both sides of the elevator hall 20, which is both aesthetically pleasing and safe. In a more specific embodiment, each water-blocking gate guide post 5 has a groove 6 in the vertical direction, and the two lifting steel wires 4 and the two ends of the water-blocking gate 1 are respectively located in the grooves 6 of the two water-blocking gate guide posts 5. In some embodiments, in order to increase the water-blocking effect, rubber gaskets can be provided between the door frame 24 and the water-blocking gate guide posts 5 and the water-blocking gate 1 for sealing.

[0030] In some preferred embodiments, locking elements 14 are provided at both ends of the top of the gate fixing plate 11. When the water-blocking gate 1 descends to the hall floor 22 to block water, the locking elements 14 are used to fix the gate fixing plate 11 relative to the water-blocking gate guide column 5 to further ensure the stability of the entire water-blocking gate 1 during use. Specifically, the locking elements 14 are bolt structures, used to lock the gate with holes provided at corresponding positions on the water-blocking gate guide column.

[0031] In other embodiments, a downward-folding plate 15 is provided on the other side of the gate fixing plate 11, and the downward-folding plate 15 is detachably connected to the bottom of the gate fixing plate 11. For example, by installing a row of letter buckles on the downward-folding plate 15 and the fixing end of the gate fixing plate 11 respectively, the buckles are fastened together when a fixed connection is required. The downward-folding plate 15 serves a decorative function and is used to balance the gate fixing plate 11 and the water-blocking gate 12 after it is folded down.

[0032] The following is a detailed description of the application and use of the elevator water-blocking device 10 with water-blocking function of this utility model in a vertical elevator system.

[0033] First, such as Figure 7 As shown, an elevator system with multiple elevator halls 20 applied to a multi-story structure with an elevator shaft includes an elevator car (not shown) that can move up and down within the elevator shaft, and an elevator door 25 arranged in each elevator hall 20. The elevator door 25 is used to allow passengers to enter and exit the elevator car when the elevator car reaches the hall station. There is a hall door sill 21 in the top door opening of the elevator door 25, and a hall door floor 22 at the bottom of the elevator door 25. An elevator water-blocking device 10 with water-blocking function is provided in the elevator hall 20.

[0034] In normal circumstances, such as Figure 1 and Figure 2 As shown, the water-blocking gate 1 of the elevator water-blocking device 10 is located above the upper sill 21 of the hall door.

[0035] When flood control and water blocking are required, the servo motor 2 is started to rotate the drum 3, which releases the lifting steel wire 4 wound on the drum 3. The water-blocking gate 1 connected to the end of the lifting steel wire 4 is released and lowered. The two ends of the water-blocking gate 1 move downward in the groove 6 of the water-blocking gate guide column 5. That is, the water-blocking gate 1 moves downward relative to the elevator hall door frame 24 until the bottom of the water-blocking gate 1 reaches the hall door floor 22. The servo motor 2 is stopped to stop the water-blocking gate 1. At this time, the water-blocking gate 1 is perpendicular to the hall door floor 22.

[0036] Loosen the nut of buckle 13, rotate the retaining strip 131 so that one end of the retaining strip 131 leaves the top of the water-blocking gate 12, causing the top of the water-blocking gate 12 to be released from the gate fixing plate 11. Rotate the water-blocking gate 12 until it is tightly against the hall floor 22, thus forming an "L"-shaped water-blocking structure for the entire water-blocking gate 1, sealing and blocking the gap 23 between the hall floor 22 and the elevator door 25, effectively blocking the water flowing to the hall floor 22. To ensure the stability of the water-blocking gate 1, if necessary (e.g., when the external water volume is large), the gate fixing plate 11 and the water-blocking gate guide post 5 can be locked by the locking part (bolt) 14. Sandbags can also be placed on the water-blocking gate 12, and a lower flap 15 can be connected to the gate fixing plate 11 facing away from the water-blocking gate 12. Figure 6 As shown.

[0037] After the flood control work is completed, loosen bolt 14, remove the lower flap 15 from the gate fixing plate 11, flip the water-retaining gate 12 so that it is close to the vertical gate fixing plate 11, rotate the locking bar 131 until one end of the locking bar 131 is perpendicular to the top of the water-retaining gate 12, tighten the nut to lock the buckle 13, and fix the gate fixing plate 11 to the water-retaining gate 12. Start the servo motor 2 again to pull the water-retaining gate 1 vertically upward through the drum 3 and the lifting steel wire 4 until the water-retaining gate reaches the set position of the upper sill of the hall and stops and maintains that position.

[0038] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
