At the same time, pathogens in the soil are washed out by floods and can also cause diseases. In order to eliminate pathogens in the environment, cut off the transmission route, and prevent and control the spread of infectious diseases, comprehensive disinfection should be actively organized after the flood. However, it is not easy to disinfect in dead corners such as drainage channels in a timely manner, causing bacteria to breed and spread the epidemic.

[0005] The patent with publication number CN110578319A discloses an underground garage waterproof device, including a water retaining system arranged at the entrance and exit of the garage, the water retaining system including a drainage trough, a locking drive device, a lifting water retaining device and a grating cover, the drainage trough is arranged underground, the locking drive device and the lifting water retaining device are arranged in the drainage trough, the locking drive device is connected to the water retaining plate in the lifting water retaining device through a transmission mechanism, and the grating cover is fixed at the notch of the drainage trough; the locking drive device can use the gravity of the vehicle to drive the water retaining plate to move up and down, and the water retaining plate in the lifting water retaining device is used to prevent rainwater at the grating cover from entering the garage; the device realizes automated operation through the vehicle gravity and mechanical structure, and has the advantages of simple structure, low production cost, energy saving and environmental protection. However, the following problems still exist:

[0006] 1. The existing technology has complex structure, inconvenient operation, low reliability and limited service life;

[0007] 2. The rainwater blocking effect of existing technologies needs to be improved;

[0008] 3. The existing technology does not have the function of disinfecting the drain. Summary of the invention

[0009] In view of the above-mentioned deficiencies existing in the prior art, the present invention provides a multi-stage filling type basement water ingress prevention device to solve the problems of the prior art, such as complex structure, inconvenient operation, low reliability, limited service life, the need to improve the rainwater blocking effect of the prior art, and the lack of the function of disinfecting the drain. The present invention also provides a method for using the water ingress prevention device.

[0010] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0011] A multi-stage filling type basement water ingress prevention device comprises a plurality of main bodies and a concrete structure, wherein the concrete structure is embedded in the road surface and flush with the road surface, and a plurality of the main bodies are installed side by side on the concrete structure and movably connected with the concrete structure;

[0012] The concrete structure includes a drainage channel, a water collection channel, a water pump and a connecting channel. The water collection channel is located on one side of the drainage channel and is lower than the drainage channel. The drainage channel is connected to the water collection channel through the connecting channel. The water pump is placed inside the water collection channel, and the water pump outlet pipe is placed outside the device.

[0013] The main body includes a water pressure plate, a first movable shaft, a first baffle, a second movable shaft, a second baffle, a first bracket and a second bracket. The water pressure plate is provided with a plurality of evenly distributed water leakage holes. One end of the water pressure plate is rotatably connected to the upper part of one side of the drain channel through the first movable shaft, and the angle between the water pressure plate and the ground is 0 to 180 degrees. One end of the first baffle is fixed to the water pressure plate, and the other end of the first baffle is movably connected to the second baffle through the second movable shaft, and the angle between the second baffle and the first baffle is 90 to 180 degrees. The first bracket is vertically installed at one end of the water pressure plate, and the second bracket is vertically installed at the other end of the first baffle, and the first bracket is connected to the second bracket;

[0014] The first baffle includes a shell, an expansion layer, a medicine storage cavity and several medicine outlet holes. The shell is a rectangular hollow plate and has an opening at one end. One end of the expansion layer is fixed inside the shell, and the other end of the expansion layer wraps the opening of the shell. The end of the shell with the opening is connected to the closed end of another adjacent shell through the expansion layer. The expansion layer and the inner wall of one side of the shell form a medicine storage cavity, and several evenly distributed medicine outlet holes are opened on one side of the shell. The shell is installed with the side with the medicine outlet holes facing the drain.

[0015] When the water volume is small, the water flows from the leak hole into the water collection channel; when it rains, the main body is flipped to prevent rainwater from entering, and the gap between the two adjacent first baffles is sealed by the expansion layer after the volume is increased, forming a solid waterproof wall to prevent a large amount of water from pouring into the underground facilities; at the same time, the second baffle with the same width as the first baffle can be lifted again according to the water volume to increase the water prevention height; when the inside of the expansion layer expands due to soaking, the volume of the expansion layer increases, compressing the space of the medicine storage cavity, and pressing the disinfection and sterilization drugs in the medicine storage cavity out from several of the drug outlet holes. After the water flow recedes, the main body is rotated and retracted into the concrete structure, and the drugs fall into the drainage channel and the water collection channel, realizing the disinfection and sterilization treatment of the drainage channel and the water collection channel. In the water collection channel, according to the entrance and exit area of ​​the underground facility, the possible water inflow is calculated in combination with the local hydrological characteristics to determine the drainage pump model, and the water is directly discharged to the outside of the baffle to prevent the underground facilities from flooding. The present invention has a simple structure, is easy to operate, stable and reliable, and has a long service life; it has a good effect in blocking a large amount of rainwater, can form a solid waterproof wall, and prevent a large amount of water from pouring into underground facilities; it can also disinfect and sterilize drainage channels and water collection channels to prevent the outbreak of diseases and epidemics after floods.

[0016] Furthermore, the first baffle also includes an anti-corrosion layer, and the anti-corrosion layer is arranged between the shell and the expansion layer.

[0017] In order to reduce the natural corrosion caused by long-term contact between the shell and the expansion layer, the anti-corrosion layer is arranged between the shell and the expansion layer. The anti-corrosion layer is a dense and corrosion-resistant oxide film formed by painting, electroplating or chemical methods on the shell surface.

[0018] Furthermore, the first baffle further includes an elastic layer, the elastic layer is made of a four-sided elastic material, and the elastic layer is arranged between the anti-corrosion layer and the expansion layer.

[0019] When the expansion layer expands, in order to prevent the expansion layer from falling off the shell due to expansion, adding four-way elastic material can make use of the elastic contraction of the four-way elastic, so that the connection between the expansion layer and the shell is more reliable and not easy to fall off.

[0020] Furthermore, the first baffle further includes a water absorbing layer, the water absorbing layer is a water absorbing material such as a sponge, and the water absorbing layer is arranged inside the expansion layer.

[0021] The addition of the water-absorbing layer enables the interior of the expansion layer to uniformly absorb water, thereby uniformly expanding, so that the disinfectant and sterilization drugs can be fully pressed out from the drug outlet, thereby improving reliability and practicality.

[0022] Furthermore, the expansion layer is a water-swellable water stop strip, and the expansion layer fills the gap in the shell and the gap between the two first baffles after swelling in water.

[0023] The water-swelling waterstop has good comprehensive performance. It has the characteristics of general rubber products and the performance of self-expanding when exposed to water. At the same time, the water-swelling waterstop is a new type of waterproof material, and its water-stopping and waterproofing effects are more reliable than general rubber. The water-swelling waterstop has many advantages such as good weather resistance, aging resistance, anti-seepage and leakage prevention, corrosion resistance, easy construction and low price.

[0024] Furthermore, the first baffle further comprises a medicine charging cover, a medicine charging port is opened on the shell, the medicine charging port leads to the medicine storage cavity, the medicine charging cover is installed at the medicine charging port, and the medicine charging cover is detachably connected to the shell.

[0025] Disinfectant and sterilization drugs can be loaded into the drug storage cavity through the drug loading port, and the drug loading cover can prevent the drugs from spreading. After using the drugs once, the drugs can be loaded into the drug storage cavity again through the drug loading port, which is more convenient to use and can be recycled many times.

[0026] Furthermore, the main body also includes a dynamic buckle and a fixed buckle, the dynamic buckle is installed on the water pressure plate, and the fixed buckle is installed on the concrete structure or the road surface. When the angle between the water pressure plate and the ground is 0 degrees, the dynamic buckle is connected to the fixed buckle.

[0027] Adding the dynamic buckle and the fixed buckle can prevent the main body from rotating due to the impact of a large amount of rainwater and losing the water-blocking ability, thereby increasing the stability and reliability of the device.

[0028] Furthermore, the main body also includes a locking structure, which is placed at the second movable axis and installed on the first baffle. When the angle between the second baffle and the first baffle is 180 degrees, the second baffle is connected to the first baffle through the locking structure.

[0029] Adding the locking structure can prevent the second baffle from rotating due to the impact of a large amount of rainwater and losing its water-blocking ability, thereby further increasing the stability, reliability and practicality of the device.

[0030] Furthermore, a settling platform is provided at the upper part of the other side of the drainage channel, the settling height of the settling platform is the thickness of the water pressure plate, and when the angle between the water pressure plate and the ground is 180 degrees, the free end of the water pressure plate is placed on the settling platform.

[0031] Adding the settling platform can make the device flush with the ground when the main body is not unfolded, thereby increasing the practicality and operability of the device.

[0032] The method for using the multi-stage filling type basement water ingress prevention device as described above comprises the following steps:

[0035] S3, setting the main body position, when it rains, flipping the main body to rotate 180 degrees around the first movable axis, fixing the water pressure plate on the concrete structure or road surface through the movable buckle and the fixed buckle, flipping the second baffle to make the angle between the second baffle and the first baffle 180 degrees, and fixing the second baffle and the first baffle through the locking structure;

[0036] S4, automatic sealing, when the outside of the expansion layer contacts rainwater, it expands, the volume of the expansion layer increases, and the gap between the two adjacent first baffles is sealed and connected by the expansion layer with the increased volume;

[0037] S5, pumping and draining water. When the amount of water is huge, the rainwater covers the top of the second baffle and flows into the drainage channel. The rainwater is then collected in the water collection channel and discharged outdoors through the water pump.

[0038] S6, automatic disinfection and sterilization. When the inside of the expansion layer expands due to soaking, the volume of the expansion layer increases, compressing the space of the medicine storage cavity, and pressing the disinfectant and sterilization drugs in the medicine storage cavity out from the several medicine outlet holes. After the water flow recedes, the main body is rotated and retracted into the concrete structure, and the drugs fall into the drain and the water collection channel, thereby achieving disinfection and sterilization of the drain and the water collection channel.

[0039] Each step can work independently, and it is only necessary to add disinfectants before use, set the main body position when rainfall occurs, and the sealing and disinfection steps can be automatically performed. The present invention has high operability and convenience.
