Description

Technical Field

[0001] The present invention relates to the technical field of disaster prevention and reduction, and in particular to a flood prevention device for intelligently sensing water volume and automatically lifting a garage. Background Art

[0002] Due to the disadvantages of underground garages being low in terrain and having slow drainage, in recent years, heavy rains often cause the underground drainage system to be overloaded during the flood season every year, causing underground garages to be flooded, resulting in property losses and personal injuries.

[0003] Most of the existing flood prevention facilities in underground garages are flood-proof sandbags and flood-proof baffles, but in actual application, there are the following problems with flood-proof sandbags and flood-proof baffles: 1. Manual operation is inconvenient and time-consuming. Placing sandbags and building baffles require manual operation, which is relatively cumbersome and time-consuming, and requires regular inspection and maintenance. In an emergency, there may not be enough time to operate; 2. Storage and cleaning are difficult. The stacking of sandbags requires a large space, and mud and moisture may remain between the sandbags. A large number of sandbags will produce certain wastes. These wastes need to be properly handled, otherwise they may cause pollution to the environment; 3. The protective effect is limited. Sandbags and baffles can usually only remain stable under a certain water level pressure. If the flood pressure exceeds their tolerance, they may be damaged or fail, causing floods to enter the garage. Summary of the invention

[0004] In order to make up for the deficiencies of the prior art, the purpose of the present invention is to provide a lifting component and a sensing component that automatically rises with the rise of water level, solving the problem that the operation of flood-proof sandbags and flood-proof baffles is time-consuming and there may not be enough time to operate them in an emergency.

[0005] In order to solve the problems of the prior art, the technical solution of the present invention is as follows: an intelligent water volume sensing and automatic lifting garage flood prevention device, including an installation base, which serves as the basis of the entire flood prevention device, and is provided with a storage groove for storing a water-retaining soft board and a lifting component, as well as an extension groove and an extension box for installing a sensing component. The water-retaining soft board is fixed in the storage groove and connected by a lifting plate. When a flood comes, it can be lifted up to block the water flow. The lifting plate is connected to the water-retaining soft board, and is moved up and down by the lifting component.

[0006] Preferably, the lifting assembly includes a motor fixed in the storage slot to provide power for the entire lifting process. The bidirectional threaded rod is driven to rotate by the motor, and the moving block is driven to move through a threaded connection. The moving block is threadedly connected to the bidirectional threaded rod and connected to the lifting rod through a bottom rotating shaft.

[0007] Preferably, multiple lifting rods are rotatably connected to each other to form a retractable structure, which rises and falls with the movement of the moving block. The sliding block is connected to the lifting rod through the top rotating shaft, and the limit block is slidably connected to the limit groove on the lifting plate to ensure that the lifting plate rises and falls smoothly.

[0008] Preferably, the sensing assembly includes a vertical rod fixed in the extension box and the extension slot, serving as a sliding track for the buoyancy ball. The buoyancy ball rises as the water level rises, and the switch is triggered by the connected first paddle and second paddle.

[0009] Preferably, the first paddle and the second paddle are designed to be tilted upward and downward, respectively, matching the shapes of the first switch (tilted downward) and the second switch (tilted upward). When the buoyancy ball rises to a certain height, the paddles trigger the corresponding switches.

[0010] Preferably, the rubber sheet is wound on a winding shaft, which is rotatably connected to a receiving groove, a pressure wheel which is pressed against one side of the rubber sheet is rotatably connected to the receiving groove, and hook rods which abut against the side of the pressure wheel are fixedly connected to both ends of the reinforcing rib rod; one end of a baffle is rotatably connected to the receiving groove, and the other end of the baffle is rotatably connected to the pressure shaft, the pressure shaft is in contact with the rubber sheet, and the bottom side of the baffle is connected to the receiving groove through a spring.

[0011] Preferably, the upper side of the front end of the storage tank is connected to the water inlet, and the lower side of the rear end is connected to the water outlet. The storage tank is rotatably connected to a water wheel, and the water wheel is transmission-connected to the buoyancy ball.

[0012] Preferably, one side of the water wheel is connected to an eccentric shaft, the eccentric shaft is rotatably connected to a connecting rod, the connecting rod is rotatably connected to a piston in a piston pump, a suction pipe is connected to a one-way water inlet valve on the side of the piston pump, and the top of the piston pump is plugged into a buoy fixed to the bottom of the buoyancy ball.

[0013] Compared with the prior art, the advantages of the present invention are as follows: The present invention is provided with a lifting component and a sensing component. When flood disasters and heavy rain occur, the buoyancy ball begins to rise after being affected by the buoyancy of water, and the motor is powered. The motor will drive the lifting plate to move upward, and the lifting plate will stretch the water retaining soft plate. As the water level continues to rise, the lifting plate will drive the water retaining soft plate to continue to rise. When the water level gradually drops from a certain height, the buoyancy ball drops due to the principle of gravity, and the motor will drive the water retaining soft plate to drop vertically, so that the flood control device has a high degree of automation, does not require manual operation, automatically senses water level changes and starts flood control measures, and each component is exquisitely designed and occupies a small space, which is suitable for installation in limited spaces such as garages.

[0014] The present invention arranges a lifting assembly, and the mounting base is installed underground. When the flood prevention function is not in use, the lifting rods are folded and retracted into the storage groove, the top of the lifting plate is parallel to the ground, and the water-retaining soft plate is stored inside the storage groove to reduce space occupancy and avoid wear by the wheels of passing vehicles. It is not easy to be deformed and damaged, and will not affect the entry and exit of vehicles.

[0015] The present invention sets a sensing component. When there is water accumulation to a certain depth on the ground, the buoyancy ball begins to rise due to the buoyancy of the water. The height of the buoyancy ball is determined by the water flow rate. When the water flow rate is large, the rotation of the water wheel drives the piston pump to run, so that the piston pump is filled with water. The buoyancy ball rises under the action of pressure to trigger a switch to realize automatic water blocking.

[0016] The water retaining soft board of the present invention is a reinforcing rib rod connected to a linear array in a rubber plate, which improves the strength of the water retaining soft board. The water retaining soft board can be rolled up to reduce the occupied space, and the groove of the pre-embedded installation base does not need to be too deep. Both ends of the reinforcing rib rod are provided with hook rods that cooperate with the clamping wheel, so that the water retaining soft board remains stable under the action of water pressure.

DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Example 1

[0027] See also Figure 1-3 , an intelligent water volume sensing and automatic lifting garage flood prevention device, including a mounting base 1, the mounting base 1 is firmly installed underground at the garage entrance or the area requiring flood prevention through anchor bolts or other fixing methods, it serves as the foundation of the entire flood prevention device, and bears the weight of all components such as a water retaining soft board 3, a lifting board 4, a lifting assembly and a sensing assembly, a storage slot 2 is designed inside the mounting base 1, which is used to store the water retaining soft board 3 when the flood prevention function is not in use to reduce space occupancy, and is also used to install the lifting assembly, at the same time, it is also provided with an extension slot 5 and an extension box 6, which are used to install the sensing assembly to ensure that the various components can be arranged in order and work together, the water retaining soft board 3 and the lifting board 4 will block the opening at the top of the storage slot 2 to prevent water from entering the storage slot 2.

[0028] See also Figure 1-3 The water-retaining soft board 3 is made of flexible materials, such as rubber or polymer composite materials. When a flood comes, the water-retaining soft board 3 is driven by the lifting component to rise and unfold from the storage groove 2 to form a barrier to prevent the flood from entering the garage. The water-retaining soft board 3 has certain flexibility and elasticity and can adapt to garage entrances of different shapes and slopes, ensuring the flood prevention effect while reducing the impact on vehicle entry and exit.

[0029] See also Figure 1-3 The lifting plate 4 is fixedly connected to the water-retaining soft plate 3, and is moved up and down by the lifting rod 11 and the sliding block 13 in the lifting assembly. When the motor 7 is started, the lifting rod 11 is driven up and down by the transmission mechanism, thereby driving the lifting plate 4 to rise and fall. The lifting plate 4 is provided with a limit block 14 and a limit groove 15 and other structures, which work with the sliding block 13 to ensure stability during the lifting process and prevent the flood control effect from being affected by shaking or deviation. By setting the lifting assembly and the sensing assembly, when flood disasters and heavy rain occur, the buoyancy ball 17 is affected by water. The buoyancy of the buoyancy ball 17 begins to rise, and the motor 7 is powered. The motor 7 will drive the lifting plate 4 to move upward, and the lifting plate 4 will stretch the water retaining soft plate 3. As the water level continues to rise, the lifting plate 4 will drive the water retaining soft plate 3 to continue to rise. When the water level gradually drops from a certain height, the buoyancy ball 17 drops due to the principle of gravity, and the motor 7 will drive the water retaining soft plate 3 to drop vertically, so that the flood control device has a high degree of automation, no manual operation is required, it automatically senses water level changes and starts flood control measures, and each component is exquisitely designed and occupies a small space, which is suitable for installation in limited spaces such as garages.

[0030] See also Figure 2-5 , lifting component, motor 7 is used as a power source, where motor 7 is a three-phase asynchronous motor, which is connected to the power grid or self-provided power supply through a power line. When the sensing component detects that the flood water level reaches a preset height, the control system sends a start signal to motor 7, and motor 7 starts to rotate. Motor 7 drives the bidirectional threaded rod 8 to rotate through a transmission mechanism such as a reducer or a coupling. The bidirectional threaded rod 8 has multiple groups of opposite threads, and each group of opposite threads can drive a corresponding group of moving blocks 9 to move in the same direction or in the opposite direction at the same time. The threads on the bidirectional threaded rod 8 match the threads in the moving block 9, so that the moving block 9 can move in the same direction or in the opposite direction at the same time. The block 9 moves axially under the rotation of the threaded rod, and the movement of the moving block 9 is transmitted to the lifting rod 11 through the bottom rotating shaft 10 and the top rotating shaft 12 and other components. The lifting rod 11 then drives the sliding block 13 and the lifting plate 4 to move up and down. By setting the lifting assembly, the mounting base 1 is installed underground. When the flood prevention function is not in use, the lifting rod 11 is folded and retracted into the storage groove 2. The top of the lifting plate 4 is parallel to the ground, and the water retaining soft board 3 is stored inside the storage groove 2 to reduce space occupancy and avoid wear by the wheels of passing vehicles. It is not easy to be deformed and damaged, and it will not affect the entry and exit of vehicles. Example 2

[0031] See also Figure 1-6, an intelligent water volume sensing and automatic lifting garage flood prevention device, based on embodiment 1, a sensing component, a buoyancy ball 17 floats as the water level rises or falls, the buoyancy ball 17 is filled with a material (such as foam) with a density less than that of water, so that it can float on the water surface, the buoyancy ball 17 can only move vertically along the vertical rod 16 and will not rotate, and the friction between the buoyancy ball 17 and the vertical rod 16 is less than the gravity of the buoyancy ball 17, and a first paddle 18 and a second paddle 19 are provided on the buoyancy ball 17. When the flood level reaches a preset height, the buoyancy ball 17 floats up and drives the first paddle 18 to contact the first switch 20, and the first When the switch 20 is squeezed, a start signal is sent to the motor 7 to drive the lifting assembly and the water-retaining soft board 3 to work to prevent the flood from entering the garage. When it is not squeezed, the power will be cut off, that is, the push-type spring switch in the prior art. At the same time, the motor 7 can cooperate with the encoder to prevent the water level from stopping at a position where the first switch 20 and the second switch 21 are continuously stressed. With the encoder, even if the second switch 21 and the second switch 21 are continuously stressed, the motor 7 will stop rotating after rotating for a few seconds to prevent the occurrence of low water level. The water-retaining soft plate 3 continues to rise, and the shapes of the first paddle 18 and the second paddle 19 on both sides of the buoyancy ball 17 are upward and downward respectively, while the contact shapes of the first switch 20 and the second switch 21 are downward and upward respectively. This design method can ensure that when the buoyancy ball 17 rises, the first paddle 18 will exert a large force on the first switch 20, and at this time, the contact part of the second paddle 19 and the second switch 21 has a certain curvature, so the second switch 21 will only be subjected to a smaller force and will not trigger the switch. Similarly, when the buoyancy ball 17 descends, the second paddle 19 and the second switch 21 also follow the same principle. By setting up a sensing component, when there is a certain depth of water on the ground, the buoyancy ball 17 begins to rise after being affected by the buoyancy of the water. When the water level gradually drops from a certain height, the buoyancy ball 17 drops due to the principle of gravity, thereby realizing automatic control of the flood control device, which is convenient to operate and has high water-retaining efficiency. When a flood comes, it can respond quickly and effectively prevent the flood from entering the garage, thereby ensuring the safety of vehicles and property in the garage.

[0032] During use, when flood disasters and heavy rain occur, there will be a certain depth of water on the ground, and the water will enter the extension groove 5. The buoyancy ball 17 begins to rise after being subjected to the buoyancy of the water. While the buoyancy ball 17 floats up, the first paddle 18 on the outer side of the buoyancy ball 17 toggles the first switch 20 bent downward during the upward floating process. The first paddle 18 contacts the first switch 20, and the motor 7 is not powered. The motor 7 will be powered only after the first switch 20 is subjected to a certain force. Since the motor 7 is electrically connected to the first switch 20 and the second switch 21 through wires, the motor 7 will drive the two-way threaded rod 8 to rotate clockwise, and the two-way threaded rod 8 drives the two moving blocks 9 of the upper pair to move toward each other. There are multiple pairs of moving blocks 9 on the two-way threaded rod 8, and the moving blocks 9 drive the bottom rotating shaft 10 to move, and the bottom rotating shaft 10 drives the lifting rod 11 to rotate, so that the multiple lifting rods 11 rotate with each other, and the lifting rod 11 drives the lifting plate 4 to move upward, and at the same time, the uppermost The lifting rod 11 drives the top rotating shaft 12 to move, and the top rotating shaft 12 drives a pair of sliding blocks 13 to move toward each other, and the sliding block 13 drives the limiting block 14 to slide along the inner wall of the limiting groove 15, and the lifting plate 4 stretches the water retaining soft plate 3. The height of the lifting plate 4 is always higher than the height of the buoyancy ball 17. When the water level continues to rise, the first paddle 18 will squeeze the different first switches 20, so that as the water level continues to rise, the lifting plate 4 will drive the water retaining soft plate 3 to rise continuously, thereby achieving the effect of automatic rising for flood prevention. When the water level gradually drops from a certain height, the buoyancy ball 17 drops due to the principle of gravity. During the process of the buoyancy ball 17 dropping, the second paddle 19 inside the buoyancy ball 17 will toggle downward to squeeze the first switch 20. At this time, the motor 7 will drive the two-way threaded rod 8 to rotate counterclockwise, so that the lifting plate 4 drives the water retaining soft plate 3 to drop vertically. As the water level continues to drop, the height of the water retaining soft plate 3 can continue to drop, and automatic dropping is achieved. Example 3

[0033] See also Figure 1-8 , an intelligent water volume sensing and automatic lifting garage flood prevention device, based on Example 1, the water-retaining soft board 3 is a rubber board 301, and a linear array of reinforcing rib rods 302 are fixedly connected inside the rubber board 301 to increase the strength of the rubber board 301 to prevent the rubber board 301 from being deformed by water pressure when blocking water, resulting in ineffective blocking. A clamping wheel 23 is arranged in the extension groove 5, so that one side of the rubber board 301 is kept in contact with the inner wall of the extension groove 5 during the process of rising with the lifting plate 4, and the two ends of the reinforcing rib rod 302 are fixedly connected to the hook rod 303, and the hook rod 303 is hooked with one side of the clamping wheel 23, and a tension force is applied to the rubber board 301 locally in the lateral direction, so that the rubber board 301 has a certain lateral strength for resisting waterlogging. The rubber board 301 is wound on the winding shaft, and the winding shaft is rotatably connected in the storage groove 2, and one end of the winding shaft is driven by the bidirectional threaded rod 8.

[0034] When the motor 7 is running, the lifting plate 4 slides upward under the drive of the lifting rod 11, and the water-retaining soft plate 3 connected to the bottom of the lifting plate moves upward accordingly, and the wound water-retaining soft plate 3 gradually moves upward. Due to the upward movement of the lifting plate 4, the originally closed storage groove 2 is opened, and a rotatably connected baffle 22 is set in the storage groove 2. The lower side of the baffle 22 is connected to the inner wall of the storage groove 2 by a spring 2202, so that the baffle 22 has a tendency to rotate downward, so that when the water-retaining soft plate 3 gradually moves upward and the water-retaining soft plate 3 on the winding shaft gradually becomes thinner, one end of the baffle 22 connected to the clamping shaft 2201 always contacts the water-retaining soft plate 3, so that the storage groove 2 remains closed. After the water-retaining soft plate 3 moves up a certain length, the reinforcing rib rod 302 is at the horizontal position where the clamping wheel 23 is located, and the hook rod 303 is hooked on the inner side of the clamping wheel 23 to prevent the reinforcing rib rod 302 from being deformed in the middle due to water pressure and leaking.

[0035] A water inlet 601 is arranged on the front side of the extension groove 5, and a drain outlet 602 is arranged on the rear side. When there is water, the water enters the extension groove 5 through the water inlet 601, and is discharged from the drain outlet 602 under the water wheel 24. The water wheel 24 is in a stationary state. When the amount of water is large, the amount of water inlet in the extension groove 5 is greater than the amount of water outlet, and the water flow drives the water wheel 24 to rotate. The side of the water wheel 24 is connected to the eccentric shaft, and the eccentric shaft is rotatably connected to the bottom end of the connecting rod 25. The top end of the connecting rod 25 is rotatably connected to the piston rod 26, and the piston rod 26 slides in the piston pump 27. The side of the piston pump 27 is connected to a water suction pipe 1702 connected to the bottom of the extension groove 5. When the piston pump 27 is running, water enters the piston pump 27 through the water suction pipe 1702. The top of the piston pump 27 is plugged with a buoy 1701, and the buoy 1701 is fixedly connected to the buoyancy ball 17, so that the buoyancy ball 17 can be triggered to run upward, and the water retaining soft board 3 is controlled to be lifted for flood control according to the amount of water flow.
