Abstract
Description
Technical Field
[0001] This application relates to the field of water conservancy and flood control technology, and in particular to a flood-proof and water-blocking gate. Background Technology
[0002] In existing technologies, low-lying areas such as underground parking garages and underpasses are highly susceptible to flooding during heavy rainfall or flooding. Because underground parking garages are located in low-lying areas, when floods occur or rainfall increases sharply, water can flow back into the garage through its steep slopes, causing flooding. Common solutions include manually piling sandbags, installing movable flood barriers, and pre-installing electric flap gates.
[0003] While manually stacking sandbags provides readily available materials, the entire process relies on manpower, resulting in a slow response time and significant time commitment. Furthermore, under strong flood pressure, the sandbags are easily washed away, making it difficult to form an effective and stable water barrier. Movable flood barriers, although providing some water-blocking capacity after installation, are cumbersome to install and dismantle, making rapid deployment in emergencies difficult. Additionally, their seal to the ground and overall structural stability are often compromised under high water pressure.
[0004] Another approach is to use electrically operated flap gates pre-embedded in the ground. These devices are typically equipped with motors and control components, which can control the opening and closing of the gate via electrical signals. However, because these critical electrical components are buried underground in a humid environment, the motors and control components are highly susceptible to damage from water ingress once flooded. This not only results in high maintenance costs but also poses a risk of electrical leakage in flooded environments, creating a safety hazard for personnel and equipment on site. Manually operated mechanical gates, on the other hand, still suffer from problems such as slow response and inconvenient operation.
[0005] This application addresses the shortcomings of existing technologies, such as slow response speed, reliance on manual labor, easy damage to electrical components, and safety hazards, by providing a flood-prevention gate that can be automatically triggered by the gravity of accumulated water and is driven entirely by mechanical transmission. This device requires no electricity and can automatically activate its water-blocking function when the accumulated water reaches a certain level, while also serving a drainage function. It aims to solve the problems of complex structure, untimely response, and poor reliability of existing water-blocking devices. Summary of the Invention
[0006] In order to improve the response speed of the gate for water blocking operations, this application provides a flood-proof water-blocking gate.
[0007] The flood-proof and water-blocking gate provided in this application adopts the following technical solution: A flood-proof gate includes a fixed base buried in the ground, a collection device arranged in the fixed base for collecting accumulated water, a drive device arranged in the fixed base for supporting the movement of the collection device, and a gate device arranged in the fixed base and linked to the drive device for blocking water. The fixed base includes a first mounting part for the collection device to move, a second mounting part arranged on the side of the first mounting part for the gate device to be placed, and a third mounting part arranged on the bottom side of the first mounting part and the second mounting part for the drive device to move.

[0013] Optionally, a first return spring is sleeved on the outer periphery of the first toothed rod. The first return spring is located inside the first mounting part, and its two ends abut against the bottom side of the first water tank and the bottom of the first mounting part, respectively.
[0014] By adopting the above technical solution, when the first water collection tank collects water and descends, the first return spring is compressed and stores elastic potential energy. After the water is discharged, the first return spring releases elastic potential energy to reset the first water collection tank, ensuring that the collection device can be used repeatedly and maintaining the normal operation of the flood prevention and water barrier gate.
[0015] Optionally, the first transmission assembly has a first sliding guide rail arranged in the third mounting portion and for the first rack to slide. The first sliding guide rail is arranged perpendicular to the bottom of the third mounting portion. A first rotating shaft is hinged in the third mounting portion and meshes with the first rack. The first rotating shaft is arranged parallel to the bottom of the third mounting portion.
[0016] By adopting the above technical solution, the first sliding guide rail can make the first rack slide perpendicular to the bottom of the third mounting part, ensuring the stability of the movement direction of the first rack; the first rotating shaft meshes with the first rack, and can effectively transmit the power generated by the movement of the first water tank when the first rack moves, providing a power basis for the operation of the subsequent drive device and gate device.
[0017] Optionally, the second transmission assembly has a second sliding guide rail arranged within the third mounting portion, on which a second rack is slidably arranged. The second rack is arranged parallel to the third mounting portion and meshes with the first rotating shaft. Simultaneously, a second rotating shaft is hinged within the third mounting portion, parallel to the first rotating shaft, and meshes with the second rack.
[0018] By adopting the above technical solution, the second sliding guide rail of the second transmission component provides a sliding path for the second rack, enabling the second rack to slide stably parallel to the third mounting part; the second rack meshes with the first rotating shaft, which can transmit the power of the first rotating shaft; the second rotating shaft is parallel to the first rotating shaft and meshes with the second rack, further realizing the transmission and conversion of power, thereby effectively transmitting the power generated by the collection device to the gate device, realizing the opening and closing of the gate device, and achieving the purpose of flood prevention and water blocking.
[0019] Optionally, the flap assembly has a first gate plate hinged to the second mounting portion, the second mounting portion having an inclined second side plate, the second side plate being at a higher height toward the first gate plate than toward the first water tank and being inclined, and a second flow channel being arranged on the side of the second side plate toward the first water tank, the second flow channel communicating with the first flow channel.
[0020] By adopting the above technical solution, the hinged first gate plate can realize the flapping action to block water; the inclined second side plate, which is higher than the first gate plate, can guide the water to flow to the first water tank; the second flow channel is connected to the first flow channel, which can make the water flow smoothly and avoid the water from accumulating in the device.

The second rotating sprockets and the first rotating sprockets are on the same plane, and a first chain is meshed on the second rotating sprockets and the first rotating sprockets.
[0022] By adopting the above technical solution, water is collected by a fixed base buried in the ground. The water causes the first water collection tank to slide within the first side plate, which in turn moves the first toothed rod. The first toothed rod meshes with the first rotating shaft, which in turn drives the second toothed rod, which meshes with it, to slide on the second sliding guide rail. The second toothed rod drives the second rotating shaft, which meshes with it, to rotate. The second rotating shaft drives the third rotating shaft, which meshes with it, to rotate. The second rotating sprockets on both sides of the third rotating shaft drive the first rotating sprockets on both sides of the first rotating shaft to rotate via the first chain, thereby driving the first gate plate of the flap assembly to rotate and open and close to block water. This effectively addresses water accumulation and performs water blocking operations, achieving flood prevention.
[0023] Optionally, waterproof pads are arranged on both sides of the first gate plate.
[0024] By adopting the above technical solution, a collection device is installed in the fixed seat of the flood-proof and water-blocking gate to collect accumulated water. The driving device uses the power generated by the accumulated water to drive the gate device to move. A filter plate is installed at the top opening of the fixed seat to allow the accumulated water to flow into the first water tank and filter out impurities. The side wall of the first water tank is provided with a filter port to cooperate with the first flow channel for drainage. A return spring is provided on the outer periphery of the first toothed rod to reset the first water tank. The first transmission component and the second transmission component realize power transmission. The first gate plate of the flap assembly is hinged to the second mounting part. The second side plate is inclined and has a flow channel that communicates with the first flow channel. The flap drive component drives the first gate plate to open and close through a sprocket and a chain. Waterproof pads are arranged on both sides of the first gate plate to enhance the waterproof performance of the gate and prevent water from seeping from both sides of the gate.
[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. The first water collection tank of the collection device collects water, and the water causes the first water collection tank to descend. The first and second transmission components of the drive device are linked, which drives the flap assembly of the gate device to open and close to block water. This method can automatically adjust according to the actual water accumulation situation without manual intervention, which solves the drawback of fixed water retaining walls that cannot be flexibly adjusted according to water level changes. It can play a timely role in blocking water under different water accumulation conditions. 2. When the accumulated water flows into the first water tank, the entire device operates automatically without the need for manual operation of the water-blocking gate; this avoids the problem of the water-blocking gate failing to function in time due to untimely response and inability of personnel to quickly reach the site to operate the gate in emergency flood situations, thus causing flooding and greatly improving the timeliness of water blocking; 3. The flood control gate consists of a fixed base, a collection device, a drive device, and a gate assembly, and has a stable structure; at the same time, it facilitates the discharge of water from the ground through the outlet pipe.

[0033] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.
[0034] This application discloses a flood-proof gate.
[0035] Reference Figure 1 and Figure 2 As shown, a flood control gate includes a fixed base 1 buried in the ground 6, a collection device 2 arranged within the fixed base 1 for collecting accumulated water, a drive device 3 arranged within the fixed base 1, and a gate device 4. The collection device 2 is located within the fixed base 1, the drive device 3 is located within the fixed base 1 and supports the movement of the collection device 2, and the gate device 4 is located within the fixed base 1 and is linked to the drive device 3. Through the cooperation of these devices, the opening and closing of the gate device 4 can be automatically controlled according to the water accumulation situation, improving the efficiency of flood control.
[0036] Reference Figure 2 As shown, the mounting base 1 includes a first mounting portion 11, a second mounting portion 12, and a third mounting portion 13. The first mounting portion 11 allows the collecting device 2 to move, the second mounting portion 12 is arranged on the side of the first mounting portion 11 for placing the gate device 4, and the third mounting portion 13 is arranged on the bottom side of the first mounting portion 11 and the second mounting portion 12 for the driving device 3 to move. The first mounting portion 11 provides space for the collecting device 2 to move, the second mounting portion 12 provides a placement position for the gate device 4, and the third mounting portion 13 provides space for the driving device 3 to move. The three parts cooperate to form a complete fixed whole, thereby realizing the installation of each device and ensuring the stability and durability of the structure.
[0037] Reference Figure 3 and Figure 4As shown, the collection device 2 includes a first water tank 21, a first side plate 22, and a first rack 23. The first water tank 21 is vertically slidably arranged in the fixed base 1 for storing water. The first side plate 22 is installed in the first mounting part 11 for the first water tank 21 to slide within the first mounting part 11, and the first side plate 22 is made of a smooth metal plate to reduce the friction when the first water tank 21 slides. The first rack 23 is arranged at the bottom of the first water tank 21 and passes through into the third mounting part 13. The first rack 23 can be a gear and rack structure to facilitate effective transmission of the drive device 3. The first water tank 21 slides downward under the gravity of the water, and the first rack 23 transmits power to the drive device 3 as the first water tank 21 slides downward.
[0038] A first opening is provided on the top of the fixed base 1, and the first opening communicates with the first mounting part 11. The side plate of the first water collection tank 21 abuts against the first side plate 22, and a sealing ring is provided on the bottom side of the first water collection tank 21, which abuts against the first side plate 22 to prevent water from seeping from the outside of the first water collection tank 21 and the gap of the first side plate 22 to the driving device 3 below, causing damage to the driving device 3. A first return spring 231 is provided circumferentially on the first gear 23. The first return spring 231 is located inside the first mounting part 11, and its two ends abut against the bottom side of the first water collection tank 21 and the bottom of the first mounting part 11, respectively. When the water level decreases, the first return spring 231 can push the first water collection tank 21 to return to its original position, preparing for the next water collection and blocking operation.
[0039] The first water collection tank 21 has several first filter ports 211 for drainage on its side wall, and a first flow channel 111 is arranged on the first side plate 22. A water outlet pipe 112 is arranged at the end of the first flow channel 111, and the water outlet pipe 112 is located within the fixed base 1 and connected to an external drain pipe. The first filter ports 211 are arranged corresponding to the first flow channels 111, meaning that under normal conditions, the opening of the first flow channel 111 covers the first filter ports 211. Water in the first water collection tank 21 flows into the first flow channels 111 through the first filter ports 211, and then is guided to the water outlet pipe 112 for discharge through each of the first flow channels 111. This allows for automatic water discharge when it rains or water enters the first water collection tank 21, preventing the activation of the gate device 4 from causing any disruption.
[0040] A filter plate 212 is arranged on the first opening. The filter plate 212 can be made of stainless steel mesh. Its function is to filter out impurities and prevent them from entering the first water collection tank 21 and affecting its normal operation. The mesh size of the filter plate 212 can be designed according to actual needs to effectively filter impurities while ensuring smooth water flow.
[0041] Reference Figure 5 and Figure 6As shown, the drive device 3 includes a first transmission assembly 31 and a second transmission assembly 32. The first transmission assembly 31 is arranged in the third mounting part 13 and is linked to the first rack 23 to drive the first water tank 21 to generate power. The second transmission assembly 32 is arranged in the third mounting part 13 and connected to the first transmission assembly 31. The second transmission assembly 32 can further transmit power to the gate device 4.
[0042] The first transmission assembly 31 has a first sliding guide rail 311 arranged in the third mounting portion 13 for sliding movement of the first rack 23. The first sliding guide rail 311 is arranged perpendicular to the bottom of the third mounting portion 13. A first rotating shaft 312 is hinged inside the third mounting portion 13 and meshes with the first rack 23. The first rotating shaft 312 is arranged parallel to the bottom of the third mounting portion 13. The first sliding guide rail 311 can ensure the stable sliding of the first rack 23, and the meshing of the first rotating shaft 312 with the first rack 23 can convert the linear motion of the first rack 23 into rotational motion.
[0043] The second transmission assembly 32 has a second sliding guide rail 321 arranged within the third mounting portion 13. A second rack 322 is slidably arranged on the second sliding guide rail 321, parallel to the third mounting portion 13, and meshes with the first rotating shaft 312. Simultaneously, a second rotating shaft 323 is hinged within the third mounting portion 13, parallel to the first rotating shaft 312, and meshes with the second rack 322. The second sliding guide rail 321 ensures stable sliding of the second rack 322, and the meshing of the second rack 322 with the first and second rotating shafts 312 and 323 further transmits power. Bearing seats are provided on both sides of the first and second rotating shafts 312 and 323, fixing them within the fixed base 1, thus better facilitating the rotation of the first and second rotating shafts 312 and 323.
[0044] Reference Figure 3 As shown, the gate device 4 includes a flap assembly 41 and a flap drive assembly 42. The flap assembly 41 is arranged in the fixed base 1, and the flap drive assembly 42 is arranged in the second mounting part 12 and connected to the second transmission assembly 32 for driving the flap assembly 41 to open and close. The flap assembly 41 can be a rotatable gate plate. When the flap drive assembly 42 receives power from the drive device 3, it can drive the flap assembly 41 to rotate, thereby realizing the water blocking function.
[0045] The flap assembly 41 has a first gate plate 411 hinged to the second mounting portion 12. The second mounting portion 12 has an inclined second side plate 412, which is inclined such that the side facing the first gate plate 411 is higher than the side facing the first water collection tank 21. A second flow channel 121 is arranged on the side of the second side plate 412 facing the first water collection tank 21, and the second flow channel 121 communicates with the first flow channel 111. The inclined arrangement of the second side plate 412 can guide the accumulated water into the second flow channel 121, and then, through the second flow channel 121, communicate with the first flow channel 111 to discharge excess water.
[0046] The flap drive assembly 42 has a first rotating shaft 421 arranged on the first gate plate 411, with first rotating sprockets 422 arranged on both sides of the first rotating shaft 421; and a third rotating shaft 324 is hinged in the third mounting part 13, the third rotating shaft 324 being meshed with a second rotating shaft 323, with second rotating sprockets 423 arranged on both sides of the third rotating shaft 324, the second rotating sprockets 423 and the first rotating sprockets 422 being on the same plane, and a first chain 424 meshing on the second rotating sprockets 423 and the first rotating sprockets 422. When the second rotating shaft 323 rotates, the first gate plate 411 can be rotated through the third rotating shaft 324 and the chain drive, realizing the function of blocking water. The flap drive assembly 42 is provided with a protective housing to prevent water from seeping in and causing damage to the first rotating sprockets 422, the second rotating sprockets 423 and the first chain 424.
[0047] Waterproof gaskets 5 are arranged on both sides of the first gate plate 411. The waterproof gaskets 5 can be made of rubber, which can improve the sealing of the gate plate and prevent water from leaking from both sides of the gate plate. All mechanical structures in this device have been waterproofed.
[0048] The implementation principle of a flood-proof gate according to an embodiment of this application is as follows: When water accumulates, it flows into the first water tank 21 through the first opening at the top of the fixed base 1. As the water level rises, the first water tank 21 slides downward under gravity, causing the first toothed rod 23 to move downward. The first toothed rod 23 meshes with the first rotating shaft 312, converting linear motion into rotational motion. The power is transmitted to the flap drive assembly 42 through the first transmission assembly 31 and the second transmission assembly 32. The flap drive assembly 42 drives the first gate plate 411 to rotate and open, thus achieving the water-blocking function.
[0049] The water in the first water collection tank 21 flows from the first filter port 211 into the first flow channel 111. This is to regulate the water level in the first water collection tank 21 under controlled water conditions, such as normal rainfall, preventing the water level from becoming too high and causing it to drop, which could lead to the gate device 4 opening accidentally and affecting the external environment. When there is a severe rainstorm or backflow of water, a large amount of water begins to accumulate on the ground 6, rushing into the first water collection tank 21. At this time, the inflow rate of the first water collection tank 21 is greater than the outflow rate, causing the water level in the first water collection tank 21 to rise rapidly. The weight of the first water collection tank 21 continuously increases, and the overall weight of the first water collection tank 21 exceeds the elastic potential energy of the first return spring 231, thereby compressing the first return spring 231 and causing the first toothed rod 23 to slide vertically downwards. During the descent of the first water tank 21, the first filter port 211 is misaligned with the inlet of the first flow channel 111, and the first filter port 211 abuts against the first side plate 22. The first filter port 211 is blocked by the first side plate 22 and cannot perform the drainage function. As the water volume in the first water tank 21 continues to increase, it continuously drives the first toothed rod 23 to move downward. The downward movement of the first toothed rod 23 drives the first rotating shaft 312 to rotate. During the rotation of the first rotating shaft 312, the second toothed rod 322 slides within the third mounting part 13. The linear sliding movement of the second toothed rod 322 is achieved through the rotational movement of the first rotating shaft 312. The sliding movement of the second toothed rod 322 also simultaneously drives the second rotating shaft 323, which meshes with it, to rotate synchronously, and the power is transmitted through the second toothed rod 322. The rotation of the second rotating shaft 323 drives the rotation of the third rotating shaft 324 meshing with it. The second rotating sprocket 423 on the third rotating shaft 324 rotates coaxially with the third rotating shaft 324. The first chain 424 on the second rotating sprocket 423 rotates and drives the first rotating sprocket 422 to rotate. The rotation of the first rotating sprockets 422 arranged on both sides rotates the first rotating shaft 421, thereby opening the first gate plate 411. When the first gate plate 411 is opened, the accumulated water can enter the first flow channel 111 through the second flow channel 121 and guide the water on the ground 6 to be discharged. The top end of the first water tank 21 in the first mounting part 11 moves to the first flow channel 111, and the outside of the first water tank 21 does not completely block the inlet of the first flow channel 111. A gap is left at the opening of the first flow channel 111 to allow the water to flow into the first flow channel 111 and discharge the water. However, when the water accumulation is severe, the drain pipe cannot drain the water, so the outlet pipe 112 is blocked. The water cannot be discharged through the first flow channel 111 and the second flow channel 121. The first gate plate 411 opens to face the impact of the water accumulation. Waterproof pads 5 are arranged on both sides of the first gate plate 411 to prevent water accumulation from seeping from both sides when the first gate plate 411 is opened.At the same time, the water accumulates, the first mounting part 11 is filled with water and maintains pressure on the first water tank 21, thereby maintaining the engagement and locking of the first gear 23 with the first rotating shaft 312, and finally maintaining the opening and closing state of the first gate plate 411.
[0050] When the drain pipe is ready for drainage, the first flow channel 111 and the second flow channel 121 guide the accumulated water to the outlet pipe 112, and then discharge it into the external drain pipe. The accumulated water on the ground 6 is slowly drained away, and the water level on the ground 6 begins to drop. When the water level on the ground 6 is the same as the ground 6, the inclined surface on the second mounting part 12 can effectively guide all the remaining water to be discharged outward from the second flow channel 121. Water accumulated in the first mounting section 11 is discharged through the gap between the first water tank 21 and the first flow channel 111, draining the water in the upper part of the first mounting section 11. When the water reaches the surface of the first water tank 21, the gravity on the first water tank 21 decreases, and the elastic potential energy generated by the first return spring 231 is greater than the downward gravity of the first water tank 21, causing the first water tank 21 to rise. During the rise of the first water tank 21, the first filter ports 211 are distributed vertically. The upper first filter port 211 on the side of the first water tank 21 first aligns with the first flow channel 111, and then drains the water from the first water tank 21. As the internal water level decreases, the first water tank 21 continues to rise, and the contact area between the first filter port 211 and the first flow channel 111 becomes larger, resulting in faster drainage. The first return spring 231 pushes the first water tank 21 to return to its original position, and the first gate plate 411 closes accordingly. This automatic response mechanism can respond to sudden flood situations in a timely and effective manner. Compared with existing technologies, it improves flood control efficiency, reduces manpower and time investment, and also improves the stability and sealing of water barriers. Furthermore, it achieves the discharge of accumulated water through water volume regulation, using a purely mechanical control method. Compared with existing technologies, it automatically opens and closes the gate device 4 based on changes in the amount of accumulated water, and can also divert and discharge accumulated water collected on the ground 6, achieving two functions with one device.
[0051] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
