Description

Technical Field

[0001] This application belongs to the field of water conservancy engineering technology, and in particular relates to a flood control gate device. Background Technology

[0002] With global warming, low-lying indoor spaces such as underground parking lots and subway stations are frequently threatened by various flood disasters.

[0003] Traditional flood control methods include building sandbags and setting up floodgates. Sandbags can withstand minor floods, but they will be washed away by strong floods of medium to high severity. Traditional floodgates usually need to be opened manually by flood control personnel, which makes them unreliable and untimely for flood control operations when floods occur.

[0004] Furthermore, since the ground is not a perfectly flat plane, gaps will remain between the floodgate and the frame, and between the floodgate and the ground. Water can easily pass through these gaps and enter the building through the floodgate's interception, still causing significant losses. Utility Model Content

[0005] To address the shortcomings of related technologies, this application provides a flood gate device that monitors flood levels through a monitoring component and drives the gate body and filling component to seal the inlet and outlet when the water level exceeds a preset value. This allows for stable and timely automatic deployment in flood control operations during flood disasters, while ensuring thorough filling of gaps. It can adapt to various complex scenarios for effective flood control.

[0023] Reference Appendix Figures 1 to 3 , Figure 1 This is a perspective view of the floodgate device of this application; Figure 2 This is a partial structural schematic diagram of the flood control gate device of this application; Figure 3 For this application Figure 2 A magnified view of a portion at point A; the specific embodiments are described below in conjunction with the above figures.

[0024] Reference Appendix Figure 1 This application provides a flood gate device for sealing the entrance and exit of a wall in the event of a flood disaster. The wall is located on a bearing plane. The flood gate device includes a track assembly 100, a gate body 200, a power assembly 300, a filling assembly 400, and a monitoring assembly 500.

[0025] The track assembly 100 is fixed to the wall and located on one side of the entrance / exit; the door 200 is slidably mounted on the track assembly 100, and the bottom wall of the door 200 is at least a preset distance away from the bearing plane; the power assembly 300 is connected to the door 200 and drives it to slide along the track assembly 100; the filling assembly 400 is mounted on the door 200 and is used to fill the gap between the closed door 200 and the entrance / exit and the preset distance; the monitoring assembly 500 is electrically connected to the power assembly 300 and the filling assembly 400.

[0026] After the monitoring component 500 detects that the water level on the bearing surface exceeds a preset value, the monitoring component 500 uses the power component 300 to make the gate 200 slide relative to the track component 100, and makes the filling component 400 cooperate with the gate 200 to close the entrance and exit.

[0027] Specifically, the door body 200 is a rectangular plate-shaped component. The size of the door body 200 is not smaller than the inlet and outlet size, and should be set based on the inlet and outlet size. The material of the door body 200 includes, but is not limited to, metal, plastic, and wood. In some embodiments, the door body 200 is made of GFRP (glass fiber reinforced plastic). GFRP has high tensile strength and stiffness, and is a lightweight material suitable for reducing the load on the track assembly 100. It also has excellent corrosion resistance, insulation, and heat resistance.

[0028] The working principle of the flood gate device is based on the real-time monitoring function of the monitoring component 500 for flood water level. Once the water depth sensor 501 detects that the flood water level on the bearing plane exceeds the preset value, the control system immediately activates the power component 300, which drives the gate body 200 to slide along the track component 100 set on one side of the wall.

[0029] The door 200 slides from a state parallel to the bearing plane to a state perpendicular to the bearing plane, thereby partially blocking the entrance and exit. The filling component 400 fills the preset gap between the bottom wall of the door 200 and the bearing plane, as well as the gap between the door 200 and the entrance and exit, to achieve the technical effect of completely sealing the entrance and exit.

[0030] It should be noted that the wall is located on a load-bearing plane, and the wall includes, but is not limited to, the walls of underground parking lots and subway stations. The end of the wall that is relatively far from the load-bearing plane is equipped with a ceiling.

[0031] The bearing surface is equivalent to the ground in the actual installation environment. However, the bearing surface is a flat and ideal plane. In reality, due to different installation environments, the slope of the ground is different at different locations. The door 200 cannot be completely attached to the ground, and floods can easily pass through the gap between the door 200 and the ground, making it difficult to guarantee effective flood resistance.

[0032] The preset spacing is a pre-set value to be filled based on the actual ground conditions. Essentially, it refers to the distance difference between the bottom wall of the door 200 and the ground. This preset spacing needs to be filled and sealed using a filling device. Since the filling medium is a highly fluid gas or liquid, it can completely fill the preset spacing between the sealed door 200 and the ground. In some embodiments, the preset spacing is set to 20mm.

[0033] The preset value is a liquid level threshold set in advance based on the actual ground conditions. In essence, it refers to the distance difference between the water surface and the ground. When the monitoring component 500 detects that the water level rise caused by the flood exceeds the preset liquid level threshold, the monitoring component 500 controls each component to perform flood control operations. In some embodiments, the preset spacing is set to 10mm.

[0034] Reference Appendix Figure 1In some embodiments, the sliding component 600 is rotatably connected to the door body 200 and slidably disposed on the track component 100. The sliding component 600 is used to make the door body 200 slide stably along the track component 100.

[0035] Specifically, the sliding component 600 constructs an auxiliary support and guide structure between the door body 200 and the track component 100. Through its rotational connection with the door body 200, the door body 200 maintains good posture stability during the sliding process.

[0036] The sliding component 600 slides along the guide rail inside or on the surface of the track component 100, which can effectively reduce the shaking and jamming caused by the weight of the door 200 or external forces, and ensure that the door 200 moves smoothly in a controlled state to open or block the entrance and exit.

[0037] The sliding component 600 not only improves the sliding accuracy, but also extends the service life of the gate body 200 and the track assembly 100, and reduces maintenance costs; the installation of the sliding component 600 enhances the durability and reliability of the flood gate device in complex or high-frequency use scenarios.

[0038] Reference Appendix Figures 1 to 3 In some embodiments, the sliding assembly 600 includes a mounting base 601 and a roller 602. At least two mounting bases 601 are fixed on the door body 200, and the two mounting bases 601 are located opposite each other at one end of the door body 200 away from or close to the bearing plane. The roller 602 is rotatably mounted on the mounting base 601 and is rolled on the track assembly 100.

[0039] Specifically, the function of the sliding component 600 is achieved by setting at least two mounting bases 601 and a corresponding number of rollers 602.

[0040] Two mounting bases 601 are fixed on the door body 200, and the two mounting bases 601 are located opposite each other at one end of the door body 200 away from or close to the bearing plane. The two mounting bases 601 cooperate with the rollers 602 to provide support points at both ends of the door body 200, thereby ensuring that the door body 200 can slide relative to the track assembly 100 to open or block the entrance and exit.

[0041] The roller 602 includes, but is not limited to, nylon wheels, rubber wheels or stainless steel rollers. The roller 602 is mounted on the mounting base 601 and can rotate freely, thereby rolling and sliding along the track assembly 100, so that the door 200 remains stable during the sliding process and reduces frictional resistance.

[0042] The mounting base 601, in conjunction with the roller 602, can significantly improve the smoothness and guidance of the sliding of the door 200, while reducing mechanical wear during the sliding process. The rolling method of the roller 602 is more efficient than the sliding friction method, which can effectively reduce energy consumption and extend the equipment life.

[0043] It should be noted that the number of mounting bases 601 should be set according to the actual situation, and the number of rollers 602 corresponds to the number of mounting bases 601; in some embodiments, the number of mounting bases 601 is set to four, with the four mounting bases 601 respectively located at the four corners of the door body 200, and the four rollers 602 rotating within the four mounting bases 601.

[0044] Reference Appendix Figure 1 and Figure 2 In some embodiments, the track assembly 100 includes a first track 101, a second track 102, and a third track 103. The first track 101 is fixed to the wall and located opposite each other on both sides of the entrance and exit. The door 200 is perpendicular to the bearing plane along the sliding direction of the first track 101. The second track 102 is located on the side of the first track 101 away from the bearing plane. The door 200 is parallel to the bearing plane along the sliding direction of the second track 102. The third track 103 is an arc-shaped track, with its two ends connected to the first track 101 and the second track 102 respectively.

[0045] Specifically, the materials selected for the first track 101, the second track 102, and the third track 103 include stainless steel, alloy steel, or surface-treated carbon steel to enhance corrosion resistance and structural strength.

[0046] The first track 101 is a straight track. The first track 101 is used to support the door 200 to slide in a direction perpendicular to the bearing plane, so that the door 200 can be opened or blocked at the entrance and exit.

[0047] The second track 102 is also a straight track. The second track 102 is used to support the door 200 to slide in a direction parallel to the bearing plane, so that the door 200 can be easily stored.

[0048] The third track 103 is an arc-shaped track, with its two ends connected to the first track 101 and the second track 102, respectively. The third track 103 is used to transition the door 200 from the first track 101 to the second track 102 during sliding. In some embodiments, the arc shape of the third track 103 is optimized into a parabolic, polygonal, or multi-segment gradually changing structure according to the size of the door 200 and the moving path, to adapt to different spatial arrangement requirements.

[0049] During the process of opening the door 200, it first rises vertically along the first track 101 to move away from the bearing plane, then transitions along the arc path of the third track 103 to the second track 102, and finally completes the horizontal sliding on the second track 102, thereby realizing the overall storage of the door 200.

[0050] The first track 101, the second track 102, and the third track 103 work together to enable the door 200 to close the entrance and exit in the direction perpendicular to the bearing plane, and also facilitate the lateral movement and concealment of the door 200 when it is not in operation. This improves the flexibility of the door 200's movement and ensures that the door 200 transitions smoothly between the track sections without jamming.

[0051] Reference Appendix Figure 2 In some embodiments, the track assembly 100 further includes limiting plates 104, with at least three limiting plates 104 respectively fixed to the end of the first track 101 away from the wall, the end of the second track 102 near the bearing plane, and the end of the third track 103 away from the wall and near the bearing plane.

[0052] Specifically, the limiting plate 104 includes, but is not limited to, metal baffles and wooden baffles. In practice, the appropriate structural materials and buffer strength should be matched according to the mass of the door 200, the sliding speed and the frequency of use.

[0053] The fixed connection between the limiting plate 104 and the first track 101, the second track 102, and the third track 103 includes welding, screwing, or embedded structure to adapt to the assembly requirements of different types of tracks.

[0054] The limiting plate 104 on the first track 101 is fixed at the end of the first track 101 away from the wall. The limiting plate 104 on the second track 102 is fixed at the end of the second track 102 away from the ceiling and close to the bearing plane. The limiting plate 104 on the third track 103 is fixed at the end of the third track 103 away from the wall and ceiling and close to the bearing plane.

[0055] The limiting plate 104 is used to limit the sliding of the door 200 to prevent the door 200 from disengaging from the slide rail assembly along with the roller 602.

[0056] During the process of opening the door 200, when the end of the door 200 away from the bearing plane slides from the first track 101 to the third track 103 and the second track 102, the end of the door 200 close to the bearing plane tends to move together. The door 200 tilts as a whole by rotating relative to the roller 602, while the limiting plate 104 on the first slide rail is used to restrict the roller 602 on the first slide rail from moving away from the wall and the first slide rail.

[0057] When both ends of the door 200 are on the second slide rail, the limiting plate 104 on the second slide rail restricts the roller 602 on the second slide rail from moving away from the ceiling and the second slide rail, so that the door 200 is stored close to the ceiling.

[0058] Reference Appendix Figure 1 and Figure 2In some embodiments, the power assembly 300 includes a sprocket 301, a drive motor 302, a transmission chain 303, and a connector 304. The two sprockets 301 are rotatably disposed on both sides of the door body 200. The drive motor 302 is disposed opposite to the sprocket 301 on the side away from the door body 200. The drive motor 302 includes an input end and an output end. The input end of the drive motor 302 is electrically connected to the monitoring assembly 500, and the output end of the drive motor 302 is used to output power. The transmission chain 303 is wound around the output ends of the sprocket 301 and the drive motor 302. The two ends of the connector 304 are rotatably connected to the transmission chain 303 and the roller 602, respectively.

[0059] Specifically, the material of sprocket 301 includes, but is not limited to, 40Cr alloy steel, with high-hardness tooth surfaces to reduce wear. The two sprockets 301 are rotatably mounted on both sides of the door body 200 to cooperate with the rotation of the drive motor 302, converting the rotational motion into the linear traction force of the transmission chain 303, thereby driving the door body 200 to slide on the slide rail assembly.

[0060] The drive motor 302 includes, but is not limited to, a stepper motor, a servo motor, or a DC motor. The drive motor 302 is equipped with an encoder to achieve position feedback control, so as to achieve precise stopping of the door 200 at a preset distance from the bearing plane.

[0061] The drive motor 302 further includes an input end and an output end. The input end of the drive motor 302 is electrically connected to the control system. After receiving the start signal from the control system, the input end of the drive motor 302 outputs low speed and high torque through the output end of the drive motor 302, thereby cooperating with the sprocket 301 to drive the transmission chain 303 to move.

[0062] The transmission chain 303 includes, but is not limited to, synchronous belts, wire ropes or screws, to adapt to different load and transmission accuracy requirements. The transmission chain 303 is a closed-loop chain structure.

[0063] The transmission chain 303 is used to convert the rotational motion output by the drive motor 302 into linear traction force, which pulls the connector 304 to drive the door 200 to slide.

[0064] The connector 304 has a U-shaped fork structure. One end is hinged to the chain link plate of the transmission chain 303 through a high-strength pin, and the other end is rotatably connected to the mounting base 601 on the door body 200.

[0065] The connector 304 is used to convert the linear tension of the transmission chain 303 into the traction force of the roller 602, driving the door body 200 to move along the track assembly 100. The connector 304 is also used to make the door body 200 bear force evenly when turning on the third track 103, reducing track wear.

[0066] After receiving the start signal from the control system, the input end of the drive motor 302, in conjunction with the sprocket 301, drives the transmission chain 303 to move. The transmission chain 303 is connected to the door body 200 through the connector 304, thereby enabling the door body 200 to move on the track assembly 100.

[0067] Reference Appendix Figure 2 In some embodiments, the power assembly 300 further includes a tensioner 305, which is rotatably disposed between the sprocket 301 and the drive motor 302. The tensioner 305 is connected to the transmission chain 303 and is used to tighten or loosen the transmission chain 303.

[0068] Specifically, the tensioner 305 material includes, but is not limited to, wear-resistant steel, engineering plastics, or rubber-coated metal to improve durability and shock absorption performance.

[0069] The tension wheel 305 is rotatably located between the sprocket 301 and the drive motor 302. The tension wheel 305 is connected to the transmission chain 303. The movement of the transmission chain 303 will drive the tension wheel 305 to rotate. The actual position of the tension wheel 305 should be adjusted according to the length and trajectory of the transmission chain 303 to enhance the compactness and maintenance convenience of the transmission chain 303.

[0070] The tensioner 305 is located on the transmission path between the sprocket 301 and the drive motor 302. The tensioner 305 rotates around its own axis and can tension or loosen the transmission chain 303 by adjusting its position or axial force.

[0071] During long-term operation, the transmission chain 303 is prone to loosening due to wear or thermal expansion and contraction. By setting the tensioner 305, the loosening problem caused by thermal expansion or wear can be effectively alleviated, and the stability and efficiency of the chain drive can be maintained.

[0072] The tensioner 305 not only provides suitable initial tension during the initial installation of the equipment, but also automatically or manually adjusts it during operation to ensure that the system is in optimal operating condition for a long time, thereby improving the response speed and accuracy of the door 200 movement and reducing the risk of chain skipping, slippage or abnormal noise.

[0073] In some embodiments, the tensioner 305 is used in conjunction with a spring-type automatic adjustment, screw-type adjustment, or hydraulic tensioning structure to adapt to different installation environments and load conditions.

[0074] When the tensioner 305 is used in conjunction with the automatic spring adjustment mechanism, it can compensate for the looseness caused by the thermal expansion or wear of the chain in real time, thereby dynamically adjusting the tension of the transmission chain 303.

[0075] In some embodiments, a first sealing groove is provided on the side of the door body 200 near the bearing plane; two second sealing grooves are respectively provided on both sides of the door body 200 adjacent to the first sealing groove; and a filling component 400 is provided in the first sealing groove and the two second sealing grooves.

[0076] Specifically, the first sealing groove is located at the bottom of the door body 200 near the bearing surface, and is used to form a bottom seal with the bearing surface; the two second sealing grooves are respectively set on both sides of the door body 200, adjacent to the first sealing groove, to seal the gap between the side of the door body 200 and the inlet / outlet.

[0077] The first sealing groove and the second sealing groove are provided with filling components 400. After the door 200 is closed to the inlet and outlet, the filling components 400 extend out of the groove to fill the gap between the door 200 and the surrounding structure.

[0078] The first sealing groove and the second sealing groove are used to limit the filling component 400 so that the filling component 400 extends in a preset direction, thereby achieving the technical effect of closing the preset distance between the door body 200 and the bearing plane and the surrounding gaps.

[0079] The first sealing groove and the second sealing groove work together to fill the component 400 to enhance the sealing ability of the door 200 in different directions, effectively preventing water from seeping in from the lower edge or side of the door 200. Through the three-dimensional distribution of the sealing layout, the water tightness and safety level of the overall sealing system are improved.

[0080] Reference Appendix Figure 1 In some embodiments, the filling component 400 includes an inflatable sealing ring 402 and an air pump 401. The inflatable sealing ring 402 is disposed in the first sealing groove and the second sealing groove, and is used to extend out of the sealing groove after inflation to fill the gap between the closed door body 200 and the inlet and outlet and the preset spacing. The air pump 401 is disposed on one side of the inflatable sealing ring 402 and is electrically connected to the monitoring component 500.

[0081] Specifically, the filling component 400 adopts an inflatable sealing structure, and its core components are the inflatable sealing ring 402 and the air pump 401 that controls the air source.

[0082] The materials used to make the inflatable sealing ring 402 include, but are not limited to, EPDM rubber, butyl rubber, EPDM rubber or composite materials. Among them, EPDM rubber has the advantages of aging resistance, stable physical and chemical properties, and good processing performance, which can achieve the technical effect of repeated use for stable sealing.

[0083] Air pump 401 includes, but is not limited to, a built-in micro pump or an external portable pump. Air pump 401 is equipped with an integrated pressure sensor to achieve automatic detection and feedback adjustment.

[0084] The inflatable sealing rings 402 are respectively arranged in the first sealing groove below the door body 200 and the second sealing grooves on both sides. After the monitoring component 500 triggers the door body 200 to slide and block the entrance and exit and separate it from the bearing plane by a preset distance, the control system further starts the air pump 401. The air pump 401 inflates the inflatable sealing rings 402. After the inflatable sealing rings 402 expand, they extend out of the sealing groove and form a tight contact with the bearing plane and the edge of the entrance and exit, thereby filling the preset distance and the surrounding gap, and achieving all-round sealing.

[0085] By utilizing the elastic deformation characteristics of the inflatable sealing ring 402 under gas pressure, it is ensured that the inflatable sealing ring 402 can adapt to the subtle differences in the shape of different walls and floors, thereby forming a continuous and uniform sealing interface.

[0086] The air pump 401 is controlled and managed by the control system, which can adjust the inflation time and pressure value as needed to ensure that the extension of the inflation sealing ring 402 meets the waterproof requirements.

[0087] Reference Appendix Figure 1 In some embodiments, the monitoring component 500 includes: a contact sensor 502, a water depth sensor 501, and a control system. The two contact sensors 502 are disposed opposite each other at both ends of the gate body 200, and are both located at the end of the gate body 200 near the bearing plane. The water depth sensor 501 is disposed on the side of the gate body 200 near the bearing plane. The control system is electrically connected to the contact sensor 502, the water depth sensor 501, the power component 300, and the filling component 400.

[0088] Specifically, the contact sensor 502 includes, but is not limited to, Hall switches, capacitive contacts, or photoelectric sensors, thereby adapting to different sensing methods and environmental requirements.

[0089] Two contact sensors 502 are disposed opposite each other at both ends of the door body 200, and both are located at the end of the door body 200 closer to the bearing plane. The contact sensors 502 are used to measure the distance between the bottom wall of the door body 200 and the bearing plane to assist the door body 200 in accurately reserving a preset distance.

[0090] Due to the different slopes of the ground, the flatness varies. The average data of the two contact sensors 502 can ensure the accuracy of the preset distance between the door 200 and the bearing plane.

[0091] The water depth sensor 501 includes, but is not limited to, a pressure sensor, a float-type water level gauge, or an ultrasonic sensor. The water depth sensor 501 is used to monitor the water level changes on the bearing surface in real time. When it detects that the water level exceeds a preset threshold, it immediately sends a first signal to the control system.

[0092] The monitoring component 500 uses a combination of a water depth sensor 501 and a contact sensor 502 to automatically detect and control the opening and closing conditions of the floodgate device.

[0093] The control system includes embedded microcontrollers, programmable logic controllers (PLCs) or IoT control platforms, and can be networked with a remote monitoring center to achieve multi-point linkage and fault alarm functions.

[0094] After receiving the first signal from the water depth sensor 501, the control system starts the power assembly 300 to drive the gate 200 to move along the track until the bottom wall of the gate 200 and the bearing plane are separated by a preset distance. Then, the second contact sensor 502 sends a second signal to the control system. After receiving the second signal, the control system shuts down the power assembly 300 and activates the filling assembly 400 to complete the sealing operation, ensuring that the sealing action is completed in a timely and accurate manner.

[0095] The control system, in conjunction with the contact sensor 502, water depth sensor 501, power assembly 300, and filling assembly 400, is used to achieve fully automated control of the entire process from water level detection to gate body 200 movement and sealing inflation, so that the floodgate device can be stably and timely automatically put into flood control operations.

[0096] When the floodgate device is used to close the entrance and exit, when the water depth sensor 501 detects that the water level on the bearing plane exceeds the preset value, the water depth sensor 501 sends a first signal to the control system. The control system sends a first motor opening signal to the input of the drive motor 302. The output of the drive motor 302 cooperates with the sprocket 301 to drive the transmission chain 303 to move. The transmission chain 303 drives the gate body 200 to slide from the second track 102 and the third track 103 to the first track 101 through the connector 304, so that the gate body 200 changes from a state parallel to the bearing plane to a state perpendicular to the bearing plane to block the entrance and exit.

[0097] When the bottom wall of the gate 200 is separated from the bearing plane by a preset distance, the two contact sensors 502 send a second signal to the control system. After receiving the second signal, the control system sends a stop signal to the input of the drive motor 302 to stop the sliding of the gate 200 on the first track 101. The control system then sends a first opening signal to the air pump 401, which inflates the air sealing ring 402 to extend the air sealing ring 402 in the first and second sealing grooves, thereby sealing the preset distance and other gaps between the gate 200 and the inlet / outlet, achieving complete closure of the inlet / outlet for flood control.

[0098] During the opening and closing process of the floodgate device, the control system sends a second opening signal to the air pump 401. The air pump 401 extracts the gas from the inflatable sealing ring 402, causing the inflatable sealing rings 402 in the first and second sealing grooves to retract. The control system sends a second motor opening signal to the input of the drive motor 302. The output of the drive motor 302, in conjunction with the sprocket 301, drives the transmission chain 303 to move. The transmission chain 303, through the connector 304, drives the gate body 200 to slide sequentially from the first track 101 and the third track 103 to the second track 102. The control system then sends a motor stop signal to the input of the drive motor 302, causing the sliding of the gate body 200 on the second track 102 to stop. The gate body 200 changes from a state of blocking the entrance and exit perpendicular to the bearing plane to a state of being retracted parallel to the bearing plane.

[0099] It should be noted that the first start signal and the second start signal sent by the control system to the air pump 401 are used to control the air pump 401 to start inflating or deflating the air sealing ring 402. The air pump 401 will automatically stop after being turned on for a preset time, or after the air sealing ring 402 reaches a preset air strength.

[0100] The control system sends a first motor start signal and a second motor start signal to the input terminal of the drive motor 302, which are used to control the output terminal of the drive motor 302 to rotate forward or reverse, thereby driving the door 200 to move in opposite directions until the control system sends a motor stop signal to the input terminal of the drive motor 302, and the output terminal of the drive motor 302 stops running.

[0101] This application provides a flood gate device. The control system sends a stop signal to the input terminal of the drive motor 302. A monitoring component 500 monitors the flood level, and when the water level exceeds a preset value, it drives the gate body 200 to cooperate with the filling component 400 to close the inlet and outlet. This allows for stable and timely automatic deployment in flood control operations during floods, while ensuring thorough filling of gaps. It can adapt to various complex scenarios for effective flood control. A sliding component 600 allows the gate body 200 to slide stably along the track component 100, preventing the gate body 200 from detaching due to force when it flips on the track component 100. The cooperation of the first track 101, the second track 102, and the third track 103 facilitates the use of the gate body 200 to close or open the inlet and outlet. A limiting plate 104 further restricts the movement direction of the gate body 200, preventing it from detaching from the first track 101 and the second track 102. The system includes a third track 103; a sprocket 301, drive motor 302, transmission chain 303, and connector 304 to drive the gate 200 to slide on the slide rail assembly, facilitating automatic closure of the entrance and exit; a tensioning wheel 305 to control the tension or relaxation of the transmission chain 303, facilitating maintenance and preventing slippage; a first sealing groove and a second sealing groove to limit the inflatable sealing ring 402, ensuring it fills the gap between the gate 200 and the entrance / exit and a preset distance in a predetermined direction, adapting to various complex scenarios for effective flood control; two contact sensors 502 to monitor the gate 200, ensuring its bottom wall is precisely spaced from the bearing plane by a preset distance; a water depth sensor 501 to monitor the flood level, enabling timely flood control response; and a control system to coordinate the orderly execution of flood control operations by all components.
