Description

Technical Field

[0001] This utility model belongs to the field of flood prevention and water blocking technology, and more specifically, relates to a flood prevention and water blocking system based on electric airbag drive. Background Technology

[0002] With the rapid pace of urbanization, the entrances to underground parking lots, garages, civil defense works, subways, and underground overpasses in communities are often located in low-lying areas. During the flood season or heavy rains, their drainage systems are easily overwhelmed, failing to drain rainwater in time. This directly leads to the flooding of numerous underground parking lots, garages, civil defense works, and subways, causing serious property losses such as vehicle damage and facility destruction, and even endangering personal safety.

[0003] Currently, the most common flood prevention devices on the market are hydrodynamic tilting flood barriers and electrically driven tilting flood barriers. Both types are typically installed by pre-burying them as a whole at the flood prevention inlet / outlet. During the flood season or heavy rain, the hydrodynamic tilting device uses its own buoyancy to raise the flood barrier, while the electrically driven device uses a motor to raise the flood barrier. Both achieve flood prevention by creating a physical barrier to block water flow. However, after in-depth research into their use, several shortcomings of the existing technology have been found:

[0004] (1) When facing complex water flow conditions such as rapid currents and whirlpools, the lifting speed of the water baffle of the hydrodynamic upturning flood control baffle device is significantly low, which greatly reduces the efficiency of the overall flood control function and makes it difficult to meet the actual flood control needs.

[0005] (2) The electric tilting flood control baffle device has a complex structure, which directly leads to its high manufacturing cost. Moreover, most of its core electromechanical components are exposed, and key components such as motors and wire ropes need to be inspected and protected regularly, which also results in high maintenance costs and poor overall economic efficiency.

[0006] (3) For the electric top-flipping flood control baffle device, during the operation, the motor drives the small drum to wind the wire rope. However, the wire rope is prone to tangling, jumping or jamming during the winding process, which brings great safety hazards to the use and seriously affects the reliability and safety of the device.

[0007] Therefore, there is an urgent need for a new type of flood control baffle system that can respond quickly, has a simple structure, low cost, high reliability, and does not require complex wire rope transmission. Summary of the Invention

[0008] To address the aforementioned deficiencies or improvement needs of existing technologies, this utility model provides a flood prevention baffle system based on electric airbag drive. When facing complex water flow conditions such as rapids and whirlpools, it can monitor water level changes in real time through a liquid level sensor and quickly activate the electric airbag mechanism to achieve rapid vertical flipping and horizontal reset of the baffle, effectively improving flood prevention efficiency. The use of electric airbag drive eliminates the need for a complex wire rope transmission structure, simplifying the device structure, reducing manufacturing and maintenance costs, and improving economic efficiency. The uniform and stable pushing force of the airbag avoids safety hazards such as wire rope tangling, skipping, or jamming, improving the system's reliability and safety. Automated control is achieved through the control system, eliminating the need for manual intervention and improving the intelligence level of flood prevention operations. The rational design of the water storage base ensures overall stability, and the setting of the limit rod ensures precise limiting and stable flipping of the baffle, adapting to different channel sizes. Overall, the system is structurally stable, highly reliable, low-cost, and highly automated, possessing good application prospects and promotional value.

[0009] To achieve the above objectives, this utility model provides a flood prevention baffle system based on an electric airbag drive, comprising a water storage base, a rotating shaft mechanism, a water baffle plate, a stainless steel side plate, an electric airbag mechanism, a liquid level sensor, and a control system communicatively connected to the liquid level sensor; wherein...

[0011] When the water baffle is in a horizontal state, it is placed inside the water storage base; when it is in a vertical state, it forms a sealed structure with the stainless steel side plates on both sides of the channel.

[0012] The electric airbag mechanism is located at the inner bottom of the water storage base; the liquid level sensor is located at the channel inlet.

[0013] The control system uses a microcontroller or a PLC controller.

[0014] Furthermore, the electric airbag mechanism includes an airbag fixed in the bottom of the water storage base, an electric air pump connected to the airbag, a solenoid valve installed in the air path between the electric air pump and the airbag, and a deflation valve installed in the air path at the other end of the airbag.

[0015] Furthermore, the electric air pump, solenoid valve, and liquid level sensor are connected to the control box of the control system via wires. The control system can control the opening and closing of the solenoid valve according to the signal from the liquid level sensor, thereby controlling the automatic inflation and deflation of the electric airbag mechanism.

[0016] Furthermore, the electric air pump, solenoid valve, and venting valve are installed in the reserved groove of the water storage base pit by means of brackets or fixing plates, or externally arranged on one side of the channel opening, and are equipped with protective covers or protective plates.

[0017] Furthermore, a limiting rod is provided between the inner bottom of the water storage base and the water baffle to limit the maximum rotation of the water baffle by 90 degrees;

[0018] The limiting rod includes a first sliding groove located at the bottom of the water storage base, a sliding block located in the sliding groove, and a two-link pull rod fixedly connected to the sliding block;

[0019] The other end of the two connecting rods is fixed to the water baffle.

[0020] Furthermore, the dual tie rod includes a first tie rod connected to the sliding block and a second tie rod connected to the baffle plate;

[0021] The second pull rod has a locking protrusion on the side away from the baffle plate; the first pull rod has a second sliding groove on the side away from the sliding block; the locking protrusion can slide in the second sliding groove.

[0022] Furthermore, the rotating shaft mechanism includes a leaf spring and a connecting member that connects to the water storage base and the baffle plate;

[0023] One end of the leaf spring of the rotating shaft mechanism is fixedly installed on the side wall of the water storage base through a connector; the other end of the leaf spring is fixedly connected to the baffle plate through a connector.

[0024] Furthermore, the bottom of the baffle plate has a hollow structure;

[0025] The water baffle is provided with sealing strips or sealing grooves on both the left and right sides.

[0026] Furthermore, the water baffle is composed of several standard-length, connectable baffle units.

[0027] In summary, compared with the prior art, the above-described technical solution conceived by this utility model can achieve the following beneficial effects:

[0028] (1) This utility model discloses a flood prevention baffle system based on electric airbag drive. When facing complex water flow conditions such as rapid currents and whirlpools, the system can monitor water level changes in real time by relying on a liquid level sensor. Once the water level reaches the preset warning value, the control system responds instantly and quickly activates the electric airbag mechanism. The airbag material is made of corrosion-resistant rubber or reinforced fiber cloth, which has a long service life and maintains performance in low-temperature environments. The airbag expands and fits tightly against the upper and lower contact surfaces. Combined with the sealing strip design, the extensibility of the airbag itself when inflated can cope with water baffles of different shapes and materials, with a wide range of applications and low requirements for the on-site environment. This utility model can respond quickly to water level changes. The airbag can complete inflation and expansion in a short time, thereby powerfully pushing the water baffle to flip vertically to the vertical working state, forming a solid physical barrier to block the water flow. This avoids the risk of waterlogging caused by the water flow impact delaying the baffle's rise, greatly improving flood prevention efficiency and effectively solving the problem of low flood prevention efficiency of existing technologies under complex water flow conditions.

[0029] (2) This utility model provides a flood prevention baffle system based on electric airbag drive, which abandons the complex steel wire rope transmission structure of traditional electric tilting devices and instead adopts electric airbag drive. Its overall structure is simpler, which not only reduces the manufacturing difficulty but also reduces the number of parts, thereby significantly reducing manufacturing costs. At the same time, core components such as electric air pumps and solenoid valves are installed inside the water storage base, which is effectively protected, reducing the frequency and intensity of maintenance of components exposed to the elements, greatly reducing maintenance costs and improving economic efficiency.

[0030] (3) The flood control baffle system based on electric airbag drive of this utility model realizes full automation of flood control operation through the close cooperation of liquid level sensor and control system. The liquid level sensor monitors water level changes in real time and transmits signals to the control system. The microcontroller or PLC controller accurately controls the operation of solenoid valve and electric air pump according to preset logic to realize the inflation and deflation of airbag, thereby controlling the vertical flipping and horizontal reset of the baffle. It can quickly respond to water level changes without manual intervention, efficiently complete the flood control task, and improve the modernization level of urban flood control and emergency response capability.

[0031] (4) The flood-proof baffle system based on electric airbag drive of this utility model has a limit rod design that can accurately limit the maximum flip angle of the baffle to 90 degrees, ensuring that the baffle is tightly fitted with the stainless steel side plate in the vertical state to form a good seal and effectively block water intrusion; under complex water flow impact or external force, it can always maintain the standard working posture of the baffle, ensuring the reliability of the flood prevention effect; during the flipping process of the baffle, the structure of the two-link tie rod makes the sliding block slide smoothly in the first sliding groove, providing stable support and guidance for the flipping of the baffle, avoiding unstable phenomena such as shaking and tilting of the baffle during the flipping process, and enhancing the stability of the entire device operation.

[0032] (5) The flood control baffle system based on electric airbag drive of this utility model is lightweight and easy to install. The airbag is small in size and light in weight. It can be folded and stored in the ground pit. It is flush with the ground surface with the water baffle. It does not occupy passage space in daily life.

[0040] Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0041] like Figures 1-4 As shown, this utility model provides a flood prevention baffle system based on electric airbag drive, installed at subway entrances, underground parking garage entrances, underground commercial area entrances, or similar low-lying entrances for emergency flood prevention. It includes a water storage base 1, a rotating shaft mechanism 2, a water-blocking plate 3, stainless steel side plates 4, an electric airbag mechanism 5, a liquid level sensor 6, and a control system communicatively connected to the liquid level sensor 6. The water storage base 1 is located in a ground pit. The stainless steel side plates 4 are arranged parallel to each other on the existing building walls or newly added structures on both sides of the passage. One end of the rotating shaft mechanism 2 is connected to the water storage base 1, and the other end is connected to the water-blocking plate 3. When in a horizontal state, the water-blocking plate 3 is placed inside the water storage base 1, and the upper surface of the water-blocking plate 3 is flush with the ground. The bottom of the water storage base 1 is hollow and flush with the surface. When the water baffle 3 is in a vertical position, it fits snugly against the stainless steel side plates 4 on both sides of the channel to form a sealed structure between the water baffle 3 and the stainless steel side plates 4. The electric airbag mechanism 5 is located at the inner bottom of the water storage base 1. The liquid level sensor 6 is located at the channel entrance and can monitor water level changes in real time. The control system adopts a microcontroller or PLC controller, which has signal receiving, processing and output functions. It can receive the signal from the liquid level sensor 6 in real time and control the operation of the solenoid valve and electric air pump on the electric airbag mechanism 5 according to the preset control logic to realize the automatic inflation or deflation of the airbag, thereby controlling the vertical flipping or horizontal reset of the water baffle 3 to realize the automatic control of flood prevention operation.

[0042] Furthermore, the water storage base 1 is made of high-strength, corrosion-resistant concrete or steel structure; its dimensions are designed according to the width of the channel and the size of the baffle plate 3 to ensure stable support of the baffle plate 3 and to provide installation space for components such as the rotating shaft mechanism 2 and the electric airbag mechanism 5, while ensuring sufficient stability during water storage; the water storage base 1 is embedded in the ground, and the ground needs to be excavated during installation. The size of the excavation should meet the installation requirements of the water storage base 1, and a certain amount of space should be reserved for the installation and maintenance of components such as the rotating shaft mechanism 2 and the electric airbag mechanism 5. After installation, the upper surface of the water storage base 1 is flush with the ground. The ground is level to ensure normal passage and aesthetics; the water storage base 1 is equipped with drainage holes or drainage pipes to drain the water accumulated in the water storage base 1, preventing water accumulation from affecting the normal operation and service life of the components. A filter screen is installed on the drainage holes or drainage pipes to prevent debris from clogging the drainage channel; the side wall of the water storage base 1 is equipped with mounting holes or mounting grooves that cooperate with the rotating shaft mechanism 2 to fix one end of the rotating shaft mechanism 2. At the same time, its internal space can accommodate the water baffle 3 when placed in a horizontal state, and ensure that there is no interference between the water baffle 3 and the water storage base 1 during the flipping process, so that the flipping action can be smoothly realized.

[0043] Furthermore, such as Figures 1-4 As shown, the rotating shaft mechanism 2 includes a leaf spring 21 and a connecting piece 22 that connects to the water storage base 1 and the baffle plate 3. One end of the leaf spring 21 is fixedly installed on the side wall of the water storage base 1 through the connecting piece 22. Specifically, it is located at the front end of the water storage base 1, close to the installation position of the baffle plate 3. The installation height should ensure that the upper surface of the baffle plate 3 is flush with the ground when it is horizontal, and can fit with the stainless steel side plate 4 to form a sealing structure when it is vertical. During installation, the horizontality and verticality of the leaf spring 21 must be ensured to ensure that the baffle plate 3 can rotate flexibly and smoothly. The other end of the leaf spring 21 is fixedly connected to the baffle plate 3 through the connecting piece 22 to ensure that the baffle plate 3 moves synchronously with the shaft during the rotation process and does not loosen or tilt. The connecting piece 22 can be a rivet or a screw.

[0044] Furthermore, such as Figures 1-4As shown, the water baffle 3 has sealing strips or sealing grooves on both sides to form a sealing structure with the stainless steel side plate 4; the height of the water baffle 3 is set according to the actual waterproof height and matches the height of the stainless steel side plate 4; the width of the water baffle 3 is set according to the actual width of the channel opening; ensuring that it can fit tightly in the vertical state to form a good sealing effect. The material of the sealing strip should have good elasticity and water resistance, be able to adapt to certain deformation and long-term water flow impact, and ensure the long-term reliability of the sealing performance; the water baffle 3 is spliced ​​from several standard length splicable baffle units; the number of baffle units is determined according to the full cross-sectional length of the channel; the water baffle 3 is made of high-strength, corrosion-resistant metal materials (such as aluminum alloy, stainless steel, etc.) or new composite materials. Its bottom has a hollow structure, which is filled with lightweight materials to reduce its weight and increase buoyancy. Its shape is rectangular or arc-shaped, and its size is designed according to the width and height of the channel and the flood prevention requirements.

[0045] Furthermore, such as Figures 1-4As shown, the electric airbag mechanism 5 is installed entirely at the inner bottom of the water storage base 1, specifically near the bottom of the baffle plate 3. This ensures that when the airbag inflates, it acts directly on the bottom center area of ​​the baffle plate 3, providing a uniform and stable pushing force while avoiding interference with other components inside the water storage base 1. The electric airbag mechanism 5 includes an airbag, an electric air pump connected to the airbag, a solenoid valve installed on the air path between the electric air pump and the airbag, and a deflation valve installed on the air path at the other end of the airbag. The airbag is fixed to the inner bottom of the water storage base 1 to prevent it from shifting or shaking during inflation and deflation, which would affect the pushing effect. The electric air pump, solenoid valve, and deflation valve are installed in the reserved groove of the pit of the water storage base 1 via brackets or fixing plates, or externally arranged on one side of the channel opening, and are equipped with protective covers or protective plates to prevent them from being flooded or damaged by other external forces. The airbag is made of high-performance rubber or PVC material that is pressure-resistant, corrosion-resistant, and aging-resistant. The dimensions are designed based on the channel width and the dimensions of the baffle plate 3 to ensure sufficient pushing force. The electric air pump is responsible for compressing air and delivering it into the airbag to inflate it. The solenoid valve is used to control the opening and closing of the air path, realizing the inflation and deflation of the airbag. It is controlled by the control system according to the signal of the liquid level sensor, opening when inflation is needed and closing when deflation is needed. The deflation valve is used to quickly discharge the gas in the airbag, causing the airbag to contract. Its deflation speed can be adjusted as needed. It is opened manually or automatically when the water level drops or when it needs to be reset, so that the baffle plate 3 automatically returns to its position under its own gravity or the torque of the rotating shaft mechanism 2. The air outlet of the electric air pump is connected to the air inlet of the solenoid valve through a high-pressure air pipe. The air outlet of the solenoid valve is connected to one end of the airbag through an air pipe, and the other end of the airbag is connected to the deflation valve through an air pipe, forming a complete air path system. All connections use sealed joints to ensure that the air path is sealed and leak-free.

[0046] Furthermore, the electric air pump, solenoid valve, and liquid level sensor are connected to the control box of the control system via wires. The control system controls the opening and closing of the solenoid valve according to the signal from the liquid level sensor, thereby realizing automatic inflation and deflation control of the electric airbag mechanism 5, and simultaneously controlling the start and stop of the electric air pump. The circuit connection uses waterproof and corrosion-resistant wires and junction boxes to ensure safe and stable operation in humid environments.

[0047] Furthermore, such as Figures 1-4As shown, a limiting rod 7 is provided between the inner bottom of the water storage base 1 and the baffle plate 3 to limit the baffle plate 3 from rotating a maximum of 90 degrees; the limiting rod 7 includes a first sliding groove provided in the inner bottom of the water storage base 1, a sliding block provided in the sliding groove, and a double pull rod 71 fixedly connected to the sliding block; the other end of the double pull rod 71 is fixed to the baffle plate 3; the double pull rod 71 includes a first pull rod 711 connected to the sliding block and a second pull rod 712 connected to the baffle plate 3; the first... The side of the second pull rod away from the water baffle 3 has a locking protrusion; the side of the first pull rod away from the sliding block has a second sliding groove; the locking protrusion can slide in the second sliding groove 713; under normal circumstances, when the water baffle 3 is placed horizontally in the water storage base 1, the sliding block of the limiting rod 7 is located in the first sliding groove near the front end of the water storage base 1, the two pull rods 71 ​​hang down naturally, and the locking protrusion is located at one end of the second sliding groove 713. At this time, the entire limiting rod 7 is in a relaxed state and does not interfere with the horizontal placement of the water baffle.

[0048] The working principle of the flood-prevention baffle system based on electric airbag drive provided by this utility model is as follows: When the water level at the site rises to the predetermined flood-prevention level, the liquid level sensor triggers the control system to issue an alarm signal through its own magnetic element, reminding the staff to take action; after receiving the alarm signal, the staff quickly go to the site to operate the electric airbag mechanism 5 to control the electric air pump to start inflating the airbag; as the airbag inflates, it generates an upward thrust, which acts directly on the bottom of the baffle 3; one end of the baffle 3 is connected to the water storage base 1 through the rotating shaft mechanism 2, and the other end is in a free state; under the action of the airbag thrust, the baffle 3 flips upward around the rotating shaft mechanism 2; at the same time, the second pull rod 712 moves upward, driving the sliding block to slide in the first sliding groove towards the rear end of the water storage base 1; as the baffle continues to flip upward and approaches a vertical state, the sliding block in the first sliding groove As the water baffle 3 continues to slide, the locking protrusion also slides accordingly within the second slide groove 713. When the water baffle 3 rotates to nearly 90 degrees, the sliding of the locking protrusion within the second slide groove 713 reaches its limit position. At this point, the end of the second slide groove 713 blocks the locking protrusion, restricting the further movement of the second pull rod 712, thereby indirectly restricting the continued rotation of the water baffle 3. Under the combined action of the airbag thrust and the limiting rod, the water baffle 3 is precisely stopped in a vertical position, tightly fitting with the stainless steel side plates 4 on both sides of the channel to form a sealed structure, effectively preventing water from entering the channel. At this time, the sliding block of the limiting rod 7 slides to its limit position within the first slide groove, the two pull rods 71 ​​are straightened, and the locking protrusion is tightly fitted with the end of the second slide groove 713. Through this mechanical limiting method, it is ensured that the water baffle is always stably kept in a vertical working state, preventing the water baffle from excessively rotating or shaking due to water flow impact or other external forces, thus ensuring the reliability of the flood prevention effect.

[0049] When the water level drops to a safe range, the level sensor 6 detects the change and triggers a corresponding signal, indicating that the flood risk has been eliminated. Based on the signal or the situation on site, staff operate the electric airbag mechanism 5 to deflate the airbag. The gas inside the airbag is released through the deflation valve, and the airbag gradually contracts. Simultaneously, the baffle plate 3, under its own weight or the torque of the rotating shaft mechanism 2, gradually flips downwards. The limit rod 7 no longer acts on the baffle plate 3. As the baffle plate 3 flips, the second pull rod 712 moves downwards, the sliding block slides in the reverse direction within the first groove, and the locking protrusion slides back from the extreme position of the second groove 713 to its initial position. When the baffle plate 3 smoothly flips back to a horizontal state, it is placed inside the water storage base 1, with its upper surface flush with the ground. The limit rod returns to its initial relaxed state, restoring normal passage.

[0050] After receiving an alarm signal from the liquid level sensor-triggered control system, staff can also control the opening and closing of the solenoid valve through the control system to achieve automatic inflation and deflation control of the electric airbag mechanism 5.

[0051] Even in the event of a power outage and lack of power, if flooding occurs and the system is unattended, it still possesses automatic flood prevention capabilities:

[0052] When flooding occurs at the entrance of the passage and the water level rises to a certain level, water rushes into the water storage base 1. Because the baffle plate 3 has a hollow structure, it will generate buoyancy in the water. When the buoyancy is greater than the weight of the baffle plate 3 and the constraint force of the rotating shaft mechanism 2, the baffle plate 3 will automatically flip upward under the action of buoyancy. After the baffle plate 3 flips to the vertical position, it fits with the stainless steel side plate 4 to form a seal, realizing the flood prevention function. This design ensures that in extreme cases, the system can still effectively protect the underground space from flooding.

[0053] Those skilled in the art will readily understand that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
