Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to a gravity-type flood control device for basements and its flood control method. Background Technology

[0002] In the event of severe rainstorms and floods, urban drainage systems often fail to effectively drain water quickly. Most urban buildings now have underground parking garages; if these garages cannot be effectively and quickly drained, large amounts of water will enter, damaging equipment and vehicles inside and causing incalculable losses. Furthermore, if electrical equipment comes into contact with water, it can cause leakage and short circuits, leading to electric shock accidents.

[0003] The information disclosed in this background section is intended only to enhance the understanding of the overall background of the invention and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Summary of the Invention

[0004] To overcome the shortcomings of existing technologies, a gravity-type flood control device and method for basements are provided to solve the safety hazard of large amounts of water entering basement garages due to the inability of existing cities to drain water quickly during severe rainstorms and floods.

[0005] To achieve the above objectives, a gravity-type flood control device for basements is provided, comprising:

[0006] The basement has a car ramp, the upper end of which is provided with a water interception ditch and a drainage ditch, the water interception ditch being located on the side of the drainage ditch away from the lower end of the car ramp;

[0007] A floodgate is provided. Side walls are constructed on opposite sides of the vehicle ramp. The side walls and the vehicle ramp enclose an entrance and exit passage. The floodgate is rotatably installed on the opposite side of the side walls. The vehicle ramp is equipped with a stopper for supporting the floodgate so that the floodgate closes the entrance and exit passage.

[0008] A water receiving tank has a receiving pit formed on the outer side of one side wall. The water receiving tank is suspended in the receiving pit in a lifting manner. A through hole is opened on one side wall in the downstream direction of the water-blocking gate. A cable is movably threaded through the through hole. One end of the cable is connected to the water-blocking gate, and the other end of the cable is connected to the water receiving tank.

[0009] A water inlet pipe is installed on the outside of the side wall. One end of the water inlet pipe is connected to the drainage ditch, and the other end of the water inlet pipe is erected above the water receiving tank. After the ground rainwater flows through the intercepting ditch and into the drainage ditch, the ground rainwater flows into the water receiving tank through the water inlet pipe. After receiving the ground rainwater, the water receiving tank falls down to cause the cable to pull the water barrier gate. The water barrier gate rotates and abuts against the anti-reverse member to close the inlet and outlet passage.

[0010] Furthermore, the receiving pit is equipped with an elastic element, which is supported by the water receiving tank.

[0011] Furthermore, the elastic element is a spring.

[0012] Furthermore, a water-blocking gate is rotatably installed on the other side wall, and a pre-embedded pipe is embedded in the car ramp, running through the opposite sides of the car ramp. Another cable is movably threaded through the pre-embedded pipe, and one end of the other cable is connected to the water receiving tank.

[0013] Furthermore, the anti-reverse component is disposed in the middle of the vehicle ramp, and when the water gate closes the access passage, the anti-reverse component abuts against the docking side of the two water gates.

[0014] Furthermore, hidden door openings are formed on opposite sides of the two side walls. Each hidden door opening has an upstream side wall facing the upper end of the vehicle passage and a downstream side wall facing away from the upper end of the vehicle passage. The water-blocking gate is rotatably installed on the downstream side wall. When the anti-reverse member abuts against the docking side of the two water-blocking gates, the two water-blocking gates abut against the downstream side wall.

[0015] Furthermore, the intercepting ditch and the drainage ditch are arranged in the same direction.

[0016] This invention provides a flood control method for a basement gravity-type flood control device, comprising the following steps:

[0017] Rainwater flows into the intercepting ditch;

[0018] After the intercepting ditch is filled with rainwater, the rainwater flows through the intercepting ditch and into the drainage ditch.

[0019] The rainwater from the ground flows into the water collection tank via a water pipe;

[0020] After collecting the rainwater from the ground, the water receiving tank falls, causing the cable to pull the floodgate.

[0021] The water-blocking gate rotates and abuts against the anti-reverse component to close the access passage, preventing rainwater from the ground from flowing back into the basement through the access passage.

[0022] The beneficial effects of this invention are as follows: The basement gravity-type flood control device of this invention relies on the increased gravity of a full water tank to pull the floodgate closed, eliminating the need for electricity or manual operation. It relies entirely on external water flow to close, avoiding the problem of power outages during heavy rain and improving safety. In the event of severe rainstorms or floods, this basement gravity-type flood control device perfectly solves the problem of water entering the underground parking garage, preventing adverse effects from these disasters, reducing losses, and providing a safe environment for residents and workers. Furthermore, this basement gravity-type flood control device is easy to operate and does not significantly increase costs. Attached Figure Description

[0027] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0028] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0029] Reference Figures 1 to 3 As shown, the present invention provides a gravity-type flood control device for basements, including: a car ramp 1, a flood barrier 2, a water receiving tank 3, and a water inlet pipe 4.

[0030] In this embodiment, the basement's car ramp 1 is inclined. The car ramp allows cars to enter and exit the basement. Side walls 11 are constructed on opposite sides of the car ramp 1. The side walls 11 and the car ramp 1 enclose the entrance / exit passage. A roof slab is poured on the upper part of the side walls 11 on both sides of the car ramp 1.

[0031] A water interception ditch a and a drainage ditch b are provided at the upper end of the vehicle ramp 1 (i.e., the end of the vehicle ramp closest to the ground and outdoors). The water interception ditch a is located on the side of the drainage ditch b away from the lower end of the vehicle ramp 1.

[0032] The water-blocking gate 2 is rotatably mounted on the opposite side of the side wall 11. In this embodiment, the water-blocking gate 2 is vertically arranged. The water-blocking gate has an opposing hinged end and a free end. The hinged end of the water-blocking gate is rotatably mounted on the inner side of the side wall via a hinge shaft.

[0033] The vehicle ramp 1 is equipped with a backstop 12. The backstop 12 is used to support the floodgate 2 so that the floodgate 2 closes the entrance and exit passage.

[0034] In this embodiment, a receiving pit is formed on the outer side of one side wall 11. The water receiving tank 3 is suspended in the receiving pit in a lifting manner. A through hole is provided on one side wall 11 in the downstream direction of the water-blocking gate 2. A cable 31 is movably threaded through the through hole on one side wall 11. One end of the cable 31 is connected to the water-blocking gate 2. The other end of the cable 31 is connected to the water receiving tank 3.

[0035] Water pipe 4 is installed on the outside of one side wall 11. One end of water pipe 4 is connected to drainage ditch b. The other end of water pipe 4 is installed above water receiving tank 3.

[0036] In this embodiment, intercepting ditch a and drainage ditch b are arranged in the same direction. The intercepting ditch is connected to the municipal pipe network. Small-flow surface rainwater can be discharged into the municipal pipe network in a timely manner after entering the intercepting ditch. However, when the surface rainwater flow is large, the intercepting ditch cannot discharge the surface rainwater into the municipal pipe network in a timely manner, so the remaining surface rainwater can only flow across the intercepting ditch to the drainage ditch.

[0037] After the surface rainwater flows through the intercepting ditch a and into the drainage ditch b, it flows into the receiving tank 3 via the water pipe 4. After receiving the surface rainwater, the receiving tank 3 drops, causing the cable 31 to pull the floodgate 2. The floodgate 2 rotates and abuts against the anti-reverse member 12 to close the inlet and outlet passage, thereby blocking the surface rainwater outside the floodgate.

[0038] In a preferred embodiment, the receiving pit is equipped with an elastic element. The elastic element is supported by the water receiving tank 3. When the water receiving tank collects rainwater from the ground, the tank begins to descend, which in turn drives the water-blocking gate to rotate via a cable until the water-blocking gate closes the entire inlet and outlet passage.

[0039] In this embodiment, the elastic element is a spring.

[0040] In a preferred embodiment, a water-blocking gate 2 is rotatably installed on the other side wall 11. A pre-embedded pipe is embedded in the vehicle ramp 1, running through opposite sides of the ramp 1. Another cable 31 is movably threaded through the pre-embedded pipe. One end of the other cable 31 is connected to a water receiving tank 3.

[0041] By pre-burying pipes, a single water tank can be used to close both water gates.

[0042] Continue reading Figure 1 The anti-reverse component 12 is located in the middle of the vehicle ramp 1. When the floodgate 2 closes the access passage, the anti-reverse component 12 simultaneously abuts against the docking side of the two floodgates 2.

[0043] Continue reading Figure 2 and Figure 3 As shown, hidden door openings c are formed on opposite sides of the two side walls 11. Each hidden door opening c has an upstream sidewall facing the upper end of the vehicle passage and a downstream sidewall facing away from the upper end of the vehicle passage. A water-blocking gate is rotatably mounted on the downstream sidewall. When the anti-reverse member 12 abuts against the mating side of the two water-blocking gates 2, the two water-blocking gates 2 abut against the downstream sidewall.

[0044] In this embodiment, the floodgate is normally housed in a concealed doorway to avoid obstructing vehicle access. When rainwater flows into the drainage ditch, the water tank descends to close the floodgate via a cable. The downstream sidewall of the concealed doorway and the anti-reverse component then support the floodgate, ensuring its stable placement within the access passage and preventing rainwater from reaching the outside of the floodgate.

[0045] This invention provides a flood control method for a basement gravity-type flood control device, comprising the following steps:

[0046] S1: Rainwater flows from the ground into intercepting ditch a.

[0047] S2: After the intercepting ditch a is filled with rainwater, the rainwater flows through the intercepting ditch a and into the drainage ditch b.

[0048] S3: Rainwater from the ground flows into the water collection tank 3 through the water pipe 4.

[0049] S4: After receiving rainwater from the ground, the water tank 3 falls, causing the cable 31 to pull the water gate 2.

[0050] S5: The water-blocking door 2 rotates and abuts against the anti-reverse part 12 to close the access passage and prevent rainwater from flowing back into the basement through the access passage.

[0051] Once the floodwaters recede and outdoor water discharges normally, the water in the tank can be drained into the basement sump, and the floodgates on the car ramps can be opened to ensure normal vehicle passage.

[0052] The basement gravity-type flood control device of this invention relies on the increased gravity of a full water tank to close the floodgate. It does not rely on electricity or manual operation for activation, but entirely on external water flow to close, avoiding the problem of power outages during heavy rain and improving safety. In the event of severe rainstorms or floods, this basement gravity-type flood control device perfectly solves the problem of water entering the underground parking garage, preventing adverse effects from these disasters, reducing damage, and providing a safe environment for residents and workers. Furthermore, this basement gravity-type flood control device is easy to operate and does not significantly increase costs.

[0053] The above description is merely a preferred embodiment of this application and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the invention involved in this application is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept. For example, technical solutions formed by substituting the above features with (but not limited to) technical features with similar functions disclosed in this application.
