[0007] The flood control mechanism includes a flood control dike, which is slidably and sealed in an installation groove. The top of the installation groove is provided with an arc-shaped protrusion, and the bottom of the flood control dike is provided with an arc-shaped groove that matches the arc-shaped protrusion. The top of the flood control dike protrudes from the ground, and diagonal strips are fixed on both sides of the installation groove. When the flood control dike is located in the installation groove, the protruding part of the top of the flood control dike and the diagonal strips on both sides combine to form a speed bump.

[0008] A water collection trough is provided on one side of the installation groove, a grid is installed on the top of the water collection trough, the water collection trough is connected to the underground drainage channel, and a connecting hole is provided between the bottom of the water collection trough and the bottom of the installation groove.

[0009] Preferably, the flood control dike is provided with sealing mechanisms on both sides. The sealing mechanism includes a side block, which is fixed on the outer ring of the top of the flood control dike. A groove is provided on the side of the side block near the side wall of the mounting groove. An elastic strip is adhered in the groove. The elastic strip is hollow and inflated with air. The elastic strip is painted red.

[0010] Preferably, a storage trough is provided at the middle of the top of the flood control dike, a push plate is slidably installed in the storage trough, a wind chime is installed on the top of the push plate, an airbag is adhered in the arc-shaped groove, and the airbag is connected to the bottom of the storage trough through an air pipe.

[0012] Preferably, the displacement of the deceleration bar in the lifting groove is greater as it gets closer to the flood control dike, and the height difference between the top of the deceleration bar and the ground is greater as it gets closer to the flood control dike, and it gradually increases.

[0013] Preferably, reflective strips are installed on both the flood-facing side of the flood dike and on the speed bumps.

[0014] A method applicable to emergency flood control projects in underground spaces, the method using the aforementioned equipment for emergency flood control projects in underground spaces.

[0015] Technical effects and advantages of the present invention: The device and method proposed in this invention, applicable to emergency flood control projects in underground spaces, have the following advantages compared with the prior art:

[0016] 1. This invention incorporates a flood control mechanism. During a sudden flood, the water level in the underground drainage channel rises rapidly. Since the water collection trough is connected to the underground drainage channel, the water level in the water collection trough also rises synchronously. The connecting hole connects the water level in the water collection trough with the water level in the installation trough, making them level. The rising water level in the installation trough pushes the flood control dike upward, causing the flood control dike to extend from the ground. As the water level rises, the height of the flood control dike that moves upward increases, thereby effectively preventing external floodwaters from flowing into the underground space and ensuring the safety of people and objects in the underground space.

[0017] 2. The present invention is equipped with a sealing mechanism that can fill the gap between the top of the flood control dike and the installation groove to form a tight fit, thereby effectively preventing silt from blocking the rise of the flood control dike, enabling rapid activation during emergency flood control and improving flood control efficiency.

[0018] 3. In this invention, once the flood control dike is raised, it becomes difficult for people and vehicles to pass. To ensure the safety of people and vehicles, this invention is equipped with multiple speed reduction strips. Once the floodwater in the sump rises, it will push the flood control dike and the speed reduction strips to rise simultaneously. Multiple speed reduction strips are arranged at equal intervals on the front side of the flood control dike. On the one hand, they can form multiple layers of water-blocking dams to block the flood and the silt in the flood. On the other hand, they can slow down and block people or vehicles in advance, serving as a warning that the flood control dike is raised and cannot be passed, thus ensuring the safety of vehicles and people.

[0023] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] This invention provides, for example Figure 1-4 The device shown is suitable for emergency flood control projects in underground spaces, including an installation groove 1, in which a flood control mechanism 2 is installed.

[0025] The flood control mechanism 2 includes a flood control dike 21, which is slidably and sealed in the mounting groove 1. The top of the mounting groove 1 is provided with an arc-shaped protrusion 22, and the bottom of the flood control dike 21 is provided with an arc-shaped groove 23 that cooperates with the arc-shaped protrusion 22. The top of the flood control dike 21 protrudes from the ground. Both sides of the mounting groove 1 are fixed with inclined strips 24. When the flood control dike 21 is located in the mounting groove 1, the protruding part of the top of the flood control dike 21 and the inclined strips 24 on both sides combine to form a speed bump.

[0026] A water collection trough 3 is provided on one side of the installation groove 1. A grating is installed on the top of the water collection trough 3. The water collection trough 3 is connected to the underground drainage channel. A connecting hole 31 is provided between the bottom of the water collection trough 3 and the bottom of the installation groove 1. In use, in order to solve the problem of sudden flooding in underground spaces, such as underground garages or underground tunnels, this invention is equipped with a flood control mechanism 2. When a sudden flood occurs, the water level in the underground drainage channel rises rapidly. Since the water collection trough 3 is connected to the underground drainage channel, the water level in the water collection trough 3 also rises synchronously. The connecting hole 31 connects the water level in the water collection trough 3 with the water level in the installation groove 1, making them level. The rising water level in the installation groove 1 pushes the flood control dike 21 to rise, causing the flood control dike 21 to extend from the ground. The higher the flood control dike 21 rises with the rising water level, the more effectively it prevents external floodwater from flowing into the underground space, ensuring the safety of people and objects in the underground space. When the flood control dike 21 rises to its highest point, the flood control mechanism 2 is activated. The arc-shaped groove 23 on the bottom side of the flood dike 21 matches the arc-shaped protrusion 22 on the top of the installation groove 1, thus forming a relative seal below the flood dike 21. This makes it difficult for floodwater to flow in from the top of the installation groove 1, preventing mud and sand carried in the floodwater from getting stuck in the gap between the flood dike 21 and the installation groove 1, thus affecting the smooth raising and lowering of the flood dike 21. When the flood dike 21 is not in operation, the inclined strips 24 fixed to the ground on both sides of the installation groove 1 will combine to form a speed bump, thereby slowing down vehicles entering the underground space. This makes the flood dike 21 serve two purposes and has a high utilization rate. At the same time, the grating installed on the top of the water accumulation trough 3 prevents large branches and other debris from falling into it, preventing blockage of the connecting hole 31 and the flow channel to the underground drainage channel.

[0027] Sealing mechanisms 4 are provided on both sides of the flood control dike 21. Each sealing mechanism 4 includes a side block 41 fixed to the outer top ring of the flood control dike 21. A groove 42 is formed on the side of the side block 41 near the side wall of the mounting groove 1. An elastic strip 43 is adhered inside the groove 42. The elastic strip 43 is hollow and inflated, and is painted red. Floodwaters carry a large amount of silt, which remains after the flood recedes. Normal entry and exit from underground spaces also bring in silt. To prevent this silt from falling into the gap between the flood control dike 21 and the mounting groove 1, this invention provides a sealing mechanism 4. The sealing mechanism 4 can fill the gap between the top of the flood control dike 21 and the mounting groove 1, forming a tight fit. This effectively prevents silt from blocking the rise of the flood control dike 21, allowing for rapid activation during emergency flood control and improving flood control efficiency.

[0028] Specifically, the elastic strip 43 is equipped with an air inlet. When the flood control dike 21 falls into the installation groove 1 under its own weight, air is injected into the elastic strip 43 through an external air pump or other air source, causing the elastic strip 43 to change from a deflated state to an expanded state. The expanded elastic strip 43 will encounter the groove wall of the installation groove 1 and be forcibly deformed, tightly fitting against the groove wall of the installation groove 1. This makes it difficult for mud and sand brought in during normal entry and exit to enter through the top of the installation groove 1. Even if some small mud and sand fall into the gap above the elastic strip 43, the space containing mud and sand is small and unlikely to affect the overall structure. The normal raising and lowering of the flood control dike 21; on the other hand, the expanding elastic strip 43 will rise with the flood control dike 21, thereby pushing the mud and sand in the gap above, and instantly recovering after being freed from the restraint of the mounting groove 1, thereby shaking off the mud and sand, playing the role of clearing mud and sand; when people or vehicles entering or leaving do not notice the raised flood control dike 21, the bright red elastic strip 43 can effectively remind children and unnoticed people entering or leaving, and the bulging elastic strip 43 will play a certain buffering role, so that people will not directly hit the flood control dike 21, protecting the personal safety of people.

[0029] A storage trough 5 is located at the middle of the top of the flood control dike 21. A push plate 6 is slidably installed inside the storage trough 5, and a wind chime 7 is installed on the top of the push plate 6. An airbag 8 is adhered inside the arc-shaped groove 23, and the airbag 8 is connected to the bottom of the storage trough 5 through an air pipe 13. When the flood control dike 21 is raised to its highest point, the arc-shaped groove 23 and the arc-shaped protrusion 22 cooperate to compress the airbag 8. The airbag 8 undergoes elastic deformation under force, thus sealing the connection between the two. At the same time, the gas is guided to the storage trough 5 through the air pipe 13, forming a sealed cavity between the bottom of the storage trough 5 and the push plate 6. Once the gas increases, it pushes the push plate 6 upward, causing the wind chime 7 to detach from the storage trough 5. In the event of a power outage, the wind will cause a loud sound, attracting people's attention to the flood control dike 21 and enabling them to promptly know that the underground space is in an emergency due to flooding. This effectively transmits information about the flood and facilitates subsequent flood control arrangements.

[0030] A filter screen 9 is detachably installed at the opening of the water collection tank 3. A plurality of lifting slots 10 are also provided between the water collection tank 3 and the installation slot 1. A deceleration strip 11 is slidably installed in the lifting slot 10. The bottom of the lifting slot 10 is connected to the inside of the water collection tank 3 and is equipped with a one-way valve that guides water from the water collection tank 3 into the lifting slot 10. The other end of the lifting slot 10 discharges the internal water through a pipe equipped with a one-way outlet valve and flushes it toward the filter screen 9. When in use, once the flood control dike 21 is raised, it becomes difficult for people and vehicles to pass. To ensure the safety of people and vehicles, this invention is equipped with multiple speed reduction strips 11. Once the floodwater in the water accumulation tank 3 rises, it will push the flood control dike 21 and the speed reduction strips 11 to rise synchronously. Multiple speed reduction strips 11 are arranged at equal intervals on the front side of the flood control dike 21. On the one hand, they can form multiple layers of water-blocking dams to block floodwater and silt in the flood. On the other hand, they can slow down and block people or vehicles in advance, which serves as a warning that the flood control dike 21 is raised and cannot be passed, thus ensuring the safety of vehicles and people.

[0031] The filter screen 9 can block mud and sand from entering, but over time, the dense mud and sand on the filter screen 9 will clog the mesh. In the event of a flood, this will prevent floodwater from entering. Therefore, this invention is equipped with multiple speed bumps 11 in conjunction with the lifting groove 10. When there is no flood, as long as the water level in the water accumulation tank 3 rises to a certain height, it will push the speed bumps 11 to rise. After the water level in the water accumulation tank 3 drops, the flood control dike 21 falls. Since the water in the water accumulation tank 3 can only be guided into the lifting groove 10 in one direction under the action of the one-way valve, the speed bumps 11 remain in the raised state. At this time, vehicles entering and exiting will step on the speed bumps. 11, that is, the compression deceleration bar 11 squeezes the water inside the lifting groove 10 downwards. The compressed water can only be discharged through the set one-way guide pipe, thereby impacting the filter screen 9. After the filter screen 9 is backflushed, it can be unclogged. Moreover, multiple lifting grooves 10 correspond to multiple pipes, and the water outlet of the pipes is circumferentially distributed below the filter screen 9. When the deceleration bar 11 is compressed in sequence, the pipe sprays water in sequence at intervals. The sprayed water flow washes the filter screen 9 locally at a fixed point. Compared with the dispersed washing of the filter screen 9, the water flow impacted at a fixed point is not easy to disperse, and the backflushing effect of the filter screen 9 is better. The automatic washing and unclogging of the filter screen 9 is realized by effectively utilizing the entry and exit of vehicles.

[0032] The displacement of the speed reduction strip 11 in the lifting groove 10 increases as it approaches the flood control dike 21. After the top of the speed reduction strip 11 rises, the height difference between it and the ground increases as it approaches the flood control dike 21, and this difference gradually increases. Because the height of the lifting groove 10 gradually increases from left to right, the final height of the speed reduction strip 11 varies after the groundwater level rises. This allows the speed reduction strip 11 to gradually slow down vehicles, reducing their kinetic energy as they reach the flood control dike 21 and ensuring the safety of the flood control dike 21.

[0033] Reflective strips 12 are installed on both the flood-facing side of the flood dike and the speed bumps 11. The reflective strips 12 increase the exposure of the flood dike and speed bumps 11, so that vehicles and pedestrians can be spotted in time, ensuring the safety of pedestrians and vehicles.
