Description
Technical Field
[0001] This invention relates to the field of municipal building technology, specifically to a highly efficient flood control and water barrier for the entrances and exits of underground sites. Background Technology
[0002] Because urban underground parking lots, underground passages, subway pedestrian passages and other facilities are located in low-lying areas, during the flood season or in areas with heavy rainfall, the underground drainage system is often overloaded by rainstorms, causing underground facilities to be flooded, resulting in significant property damage and personal injury.
[0003] Currently, the common waterproofing methods for underground facilities are waterproof sandbags and waterproof barriers. Waterproof sandbags require a lot of manpower to install, and are inconvenient to install and remove, resulting in low efficiency. Waterproof barriers also generally need to be installed in advance, but if the actual rainfall is not large, installing the barriers in advance can easily affect the normal passage of vehicles. Waterproof sandbags and waterproof barriers need to be stored in a special location, which takes up extra space. Summary of the Invention
[0004] This invention provides a highly efficient flood control and water barrier for the entrances and exits of underground sites, which is remotely controllable and easy to use.
[0005] This invention provides a highly efficient flood control and water-blocking facility for underground site entrances and exits, comprising a rotating plate and a fixing device. The rotating plate has a ramp at its front. The fixing device includes a fixing plate and columns on both sides of its front. The fixing plate has a ramp at its rear. Tie rods are installed on both sides of the front of the fixing plate, with the other end of each tie rod hinged to the rotating plate. The rear of the rotating plate corresponds to the front wall of the fixing plate. A sealing strip is installed on the fixing device, sealing the rotating plate to the fixing device when it rotates and stands upright. A monitoring and alarm system is installed on the fixing device, and both the drive device and the monitoring and alarm system are connected to the control system. A counterweight device is installed inside the column. The counterweight device is vertically slidable inside the column via a guide mechanism, and a limiting structure is provided on the guide mechanism. The counterweight device includes a counterweight block, on which a rope-pressing wheel is installed. A hinged arm is connected to the counterweight block, and a spring rod is provided between the hinged arm and the counterweight block. A slot is provided on the column corresponding to the position of the hinged arm. A pressure plate roller is provided below the hinged arm. When the rotating plate is in a flat state, the position of the pressure plate roller corresponds to the upper surface of the rotating plate. When the rotating plate is in an upright state, the pressure plate roller corresponds to the slope at the front of the rotating plate. A speed reducer is installed inside one of the columns. A steel rope is installed at the output end of the speed reducer. The steel rope passes around the pressure rope wheel and its end is connected to the front of the rotating plate. Another steel rope is also installed at the output end of the speed reducer. The steel rope passes through the fixed plate and enters the column. It passes around the pressure rope wheel and its end is connected to the front of the rotating plate.
[0006] Furthermore, a fixed pulley is provided on the upper part of the column, and the steel rope connected to the output end of the reducer passes around the fixed pulley from bottom to top and then passes around the pressure rope wheel from top to bottom.
[0007] Furthermore, steel rope grooves are provided on both sides of the rotating plate. The steel rope grooves are deeper near the slope and shallower closer to the fixed plate. No steel rope grooves are provided at the corresponding positions of the sealing strip.
[0008] Furthermore, the sealing strip is U-shaped, with its bottom set on the front wall of the fixed plate and its sides set on the columns, and its position set on the outside of the folding arm. The front part of the rotating plate corresponding to the sealing strip is not provided with a slope.
[0009] This invention provides a high-efficiency flood control and water barrier facility for underground entrances and exits. It is low in cost, easy to install and maintain, and does not require damage to existing underground passages and road surface facilities. Through remote control of the speed reducer, the rotating plate can be quickly erected to achieve a sealing and flood control effect in conjunction with the sealing strip and fixing device. The rotating plate is used as a speed bump and is erected when flood control is needed to block water and prevent flooding. The device is easy to use and improves work efficiency.

[0011] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0012] like Figure 1-11 As shown, the present invention provides a highly efficient flood control and water barrier for underground site entrances and exits, including a rotating plate 1 and a fixing device, such as... Figure 10 As shown, the front of the rotating plate is provided with a ramp 2 to facilitate the smooth passage of vehicles; the rear is provided with rounded corners or a curved surface to reduce friction between the rotating plate and the front wall of the fixed plate and the ground during rotation, and can also be designed as a semi-circle; hinge shafts 3 are provided on both sides of the rear end of the rotating plate to facilitate hinge connection with the fixed device. The fixing device includes a fixing plate 4, such as Figure 12 As shown, a ramp 2 is provided at the rear of the fixing plate, and tie rod grooves 5 are provided on both sides of the front of the fixing plate. Tie rods 6 are installed in the tie rod grooves, as shown. Figure 11 As shown, the pull rod includes a hinge ring 7 that mates with the hinge shaft, a sleeve 8 is provided on the hinge ring, a spring 9 is provided inside the sleeve, a retaining ring 10 is provided at the opening of the sleeve to limit the spring, a baffle 11 is provided between the spring and the bottom surface of the sleeve, a support column 12 is provided on the baffle, and the other end of the support column is fixed in the pull rod groove provided on the fixing plate. By properly designing the spring's stroke, the spring will always be in a compressed state. When the rotating plate is laid flat, the rotating plate will be pressed against the front wall of the fixed plate under the force of the spring, thus fixing the rotating plate. When the rotating plate is upright, the rotating plate will be pressed against the fixed plate and the column under the force of the spring, compressing the sealing strip and increasing the sealing effect. like Figure 1-5 As shown, the fixing device also includes columns 13 set on both sides of the front of the fixing plate; a sealing strip 14 is set on the fixing device, specifically set on the front wall of the fixing plate and in front of the columns, and positioned on the outside of the folding arm. This setting allows the slot 15 opened on the column for the folding arm to be inside the sealing area, preventing water from entering; no vehicles pass through the area corresponding to the sealing strip on the rotating plate, and no ramp is set here. This design allows for more contact area between the rotating plate and the columns of the fixing device. Combined with the extended sealing strip, it can block deeper water levels. like Figure 12 As shown, in order to facilitate construction and use, matching notches 33 are provided on the left and right sides of the rear end of the fixing plate to facilitate its cooperation with the walls on both sides of the entrance and exit of the underground site; countersunk holes are also provided on the fixing plate, and the fixing plate is fixedly connected to the ground by bolts. like Figure 6-9As shown, a counterweight device 16 is installed inside the column. The counterweight device can be vertically slidably installed inside the column through a guide mechanism 17. A limiting structure 18 is provided on the guide mechanism. In this embodiment, the guide mechanism is a guide post installed inside the column, and the counterweight device is provided with a guide hole that cooperates with the guide post. The limiting structure is a limiting block.
[0013] The counterweight device includes a counterweight block 19, on which a pressure rope wheel 20 is mounted; a hinged folding arm 21 is connected to the counterweight block, and a spring rod 22 is provided between the folding arm and the counterweight block. The spring rod can be a spring telescopic rod, a gas strut rod, etc.; a bellows rubber cover 23 is provided between the folding arm and the counterweight block to prevent debris, water, etc. from entering and to protect the spring rod and the hinged structure; a slot 15 is provided on the column corresponding to the position of the folding arm to avoid obstructing the extension and vertical movement of the folding arm, and a rubber cover 24 is provided at the slot to prevent debris, water, etc. from entering the column; a pressure plate roller 25 is provided below the folding arm, and when the rotating plate is in a flat position, the position of the pressure plate roller corresponds to the upper surface of the rotating plate.
[0014] like Figure 4 As shown, a speed reducer 34 is installed inside one of the columns, mounted on the side wall of the column. A fixed pulley 26 is installed above the speed reducer inside the column. A steel rope 27 connected to the output end of the speed reducer passes over the fixed pulley from bottom to top and then passes over the pressure rope pulley from top to bottom. Another steel rope is also installed at the output end of the speed reducer. This steel rope passes downwards over the first reversing pulley 28, through the fixed plate, then over the second reversing pulley 29, and upwards into the column. It then passes over the end of the pressure rope pulley and connects to the front of the rotating plate. This allows for synchronous movement on both sides, preventing asynchrony when the rotating plate is erected. The fixed pulley ensures that the force on the column is vertically downward, increasing the column's stability. Through holes are provided on the fixed plate to allow the steel rope to pass through. For ease of use, additional features can be machined on the fixed plate. Figure 12 The trough shown is designed to facilitate the passage of steel cables, and a cover plate is then installed above the trough 30 to prevent debris, water, etc. from entering the trough. like Figure 2 , 3 As shown in Figure 10, in order to prevent the steel rope from leaking out of the rotating plate, steel rope grooves 31 are provided on both sides of the rotating plate. The steel rope grooves are deeper on the side closer to the slope and shallower on the side closer to the fixed plate. No steel rope grooves are provided on the rotating plate at the position corresponding to the sealing strip. This ensures that when the rotating plate is upright, the contact area between the sealing strip and the rotating plate is a plane, which improves the sealing effect.
[0015] like Figure 1As shown, a monitoring and alarm system 32 is installed on the column. Both the drive unit and the monitoring and alarm system are connected to the control system. The monitoring and alarm system includes an audible and visual alarm and a monitoring camera installed on the column. The audible and visual alarm, the monitoring camera, and the speed reducer are all connected to the control system. To avoid accidents, the technical solution provided by this invention requires manual confirmation and does not employ an automatic method.
[0016] The following details need to be explained in the actual use of this invention: Normally, the rotating plate is laid flat. The counterweight device's folding arm presses down on the rotating plate through rollers, which can improve the stability of the rotating plate and prevent it from bouncing up and causing danger when vehicles pass by. With the cooperation of the counterweight device, the steel cable is in a taut state. The pressure wheel of the counterweight device presses down the steel cable. Part of the steel cable on the rotating plate is in the steel cable groove. In the parts without the steel cable groove, the steel cable is almost in contact with the surface of the rotating plate. The biggest function of this design is to prevent the steel cable from being outside the rotating plate and avoid the danger of tripping when people pass by. Operators, monitoring the alarm system, detected a gradual increase in ground water and determined whether flood control measures were necessary. Generally, the device needs to be activated when a trickle forms on the ground. The operator first activates the audible and visual alarm system to warn vehicles that the underground entrance / exit is about to close. After ensuring safety, the operator issues a control signal, activating the reducer and retracting its steel cable. Initially, the steel cable corresponding to the rotating plate is nearly horizontal, so it's insufficient to lift the plate. At this point, the cable lifts the counterweight device via the pressure pulley, and the counterweight device moves upward under the guidance of the guide post. Simultaneously, the angle between the steel cable and the rotating plate gradually increases. At a certain angle, the cable lifts the rotating plate, and as the counterweight device moves upward, the front of the rotating plate... The plate slowly rotates upwards; after the counterweight reaches its limit, it stops rising, and the rotating plate continues to rotate under the pull of the steel rope. During this process, the upper surface of the rotating plate pushes the pressure plate rollers, causing the folding arm to fold upwards, and the spring rod to be compressed. Finally, the rotating plate is fully erected, the pressure plate rollers cooperate with the ramp, and the rotating plate, under the action of the steel rope and the pull rod, compresses the sealing strip on the fixing device. The sealing strip between the rotating plate and the fixing device forms a sealed flood prevention and water barrier. The reducer locks to prevent the folding arm from being springed open by the force of the spring rod. At this time, the water accumulation outside the entrance and exit of the underground site is blocked. The audible and visual alarm system continues to operate throughout this process and the entire process of the rotating plate erecting. When the floodwater outside the underground entrance recedes and the entrance is reopened to traffic, the operator issues a control signal, the reducer activates, reverses to release the steel cable, and the counterweight moves downward along the guide post under gravity. The elastic rod extends and pushes the rotating plate from a vertical position to an inclined position through the pressure plate wheel. With the help of the rotating plate's own weight, the rotating plate rotates back to a horizontal position, and the reducer locks again. With the help of the counterweight, the steel cable is taut, and the pressure wheel of the counterweight presses the steel cable down.
[0017] Obviously, the reducer can be a manual / automatic reducer, which can be operated manually even when the power is off. For ease of construction, matching notches 31 are provided on the left and right sides of the rear end of the fixing plate to facilitate matching with the walls on both sides of the entrance and exit of the underground site; the fixing plate is also provided with countersunk holes, and the fixing plate is fixed to the ground by bolts.
[0018] The length of the pull rod can be adjusted, and the adjustment method is something that those skilled in the art can achieve, so it will not be described in detail here; by adjusting the length, the magnitude of the force between the rotating plate and the fixing device can be changed, thereby adjusting the sealing performance.
[0019] As can be seen from the above technical solutions, the connections between the rotating plate and the counterweight, as well as between the rotating plate and the fixed device, are not rigid connections. This not only increases the sealing performance but also prevents damage to the device from vibrations caused by passing vehicles, thus extending the device's service life.
[0020] This invention provides a high-efficiency flood control and water barrier facility for underground entrances and exits. It is low in cost, easy to install and maintain, and does not require damage to existing underground passages and road surface facilities. It can quickly raise the rotating plate to achieve the flood control effect. In normal conditions, the rotating plate is placed on the road surface and used as a speed bump. When flood control is needed, it is erected to block water and prevent flooding. It does not affect vehicle traffic, is easy to use, and improves work efficiency.
[0021] The above embodiments are provided for those skilled in the art to implement or use the present invention. Those skilled in the art can make various modifications or changes to the above embodiments without departing from the inventive concept of the present invention. Therefore, the protection scope of the present invention is not limited to the above embodiments, but should be the maximum scope that conforms to the innovative features mentioned in the claims.
