Description

Technical Field

[0001] The present invention belongs to the technical field of sewage storage and regulation, and in particular relates to overflow sewage storage and regulation equipment and a method for using the same. Background Art

[0002] Combined sewer overflow pollution is also commonly referred to as CSO. It refers to the pipe network basin system in the urban drainage system that is a combined area. On sunny days, the sewage flow in the drainage pipe is relatively small, so it can be transported to the downstream sewage treatment plant through the intercepting pipe for relevant treatment. However, on rainy days, the flow exceeds the design capacity of the pipe network system, and overflow will occur. The pollutants remaining and deposited in the pipe system on sunny days will be picked up and flow directly into the surrounding water bodies without any treatment, causing pollution. The urban non-point source pollution caused by CSO has become an indicator that cannot be ignored in the current urban water environment pollution control. The pollutants discharged into the water body by combined sewer overflow pollution have seriously threatened the ecological environment of the water body, and have had a significant impact on the recovery of water body functions and the regulation of ecological balance.

[0003] In order to effectively solve the problem of combined sewer overflow pollution, it is necessary to build rapid purification facilities such as regulating and storage ponds to achieve regulation and storage and primary treatment. However, the existing regulating and storage ponds are generally just simple pools that only have the functions of storing water, releasing water and simple sewage treatment. Especially in the early stage of rainfall, rainwater, dirt in upstream pipes, and pollutants in the atmosphere and the surface will be introduced into the regulating and storage ponds. The above-mentioned regulating and storage ponds are difficult to effectively treat these substances, resulting in these substances being directly introduced into the sewage treatment plant, which in turn causes an overload impact on the sewage treatment plant. In addition, when the regulating and storage ponds are used for a long time, a large amount of dirt is likely to adhere to the bottom of the pond. If these dirt are not cleaned in time, it will affect the normal use of the regulating and storage ponds.

[0004] Therefore, in response to the above technical problems, it is necessary to provide an overflow sewage storage device and a method for using the same.

[0005] The information disclosed in this background technology section is only intended to enhance understanding of the overall background of the invention and should not be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to a person skilled in the art. Summary of the Invention

[0006] The purpose of the present invention is to provide an overflow sewage storage device and a method of using the same, which can solve the problems of poor storage effect of existing storage tanks and difficulty in cleaning the dirt at the bottom of the tank.

[0007] In order to achieve the above object, a specific embodiment of the present invention provides the following technical solutions:

[0008] An overflow sewage storage device comprises: a storage tank body, a plurality of columns, a suspension capture mechanism, a plurality of capture cleaning mechanisms and an auxiliary capture mechanism;

[0009] The regulating reservoir body is provided with a first partition plate and a second partition plate, and a first compartment pool, a second compartment pool and a third compartment pool are formed between the first partition plate, the second partition plate and the inner wall of the regulating reservoir body. The regulating reservoir body is connected to a liquid inlet pipe and a liquid discharge pipe, the liquid inlet pipe is connected to the first compartment pool, and the liquid discharge pipe is connected to the third compartment pool;

[0010] The plurality of columns are all installed in the first compartment pool;

[0011] The suspension capture mechanism is arranged in the first compartment pool and is slidably arranged on the plurality of columns;

[0012] A plurality of the capture-type cleaning mechanisms are installed in the suspension capture mechanism;

[0013] The auxiliary capture mechanism is installed on the suspended capture mechanism and covers the capture cleaning mechanism;

[0014] During rainfall, the suspended capture mechanism is suspended on the liquid surface of the first compartment pool, and the suspended matter and pollutants in the first compartment pool are intercepted by the joint action of the suspended capture mechanism, the capture-type cleaning mechanism and the auxiliary capture mechanism; when cleaning the bottom of the first compartment pool, the suspended capture mechanism descends to the bottom of the column, and multiple capture-type cleaning mechanisms are used to clean the bottom of the first compartment pool.

[0015] In one or more embodiments of the present invention, a connecting pipe is installed on each of the first partition plate and the second partition plate, and a control valve is installed on the connecting pipe. The first compartment pool, the second compartment pool and the third compartment pool are respectively connected through the connecting pipe. When the control valve is opened, the liquid in the first compartment pool, the second compartment pool and the third compartment pool will circulate with each other to discharge the liquid in the first compartment pool, the second compartment pool and the third compartment pool;

[0016] A plurality of sewage pipes are installed on the side wall of the regulating and storage tank body. The first compartment tank, the second compartment tank and the third compartment tank are connected to the outside world through the sewage pipes respectively, and the liquid in the first compartment tank, the second compartment tank and the third compartment tank can be discharged and introduced into the sewage treatment plant.

[0017] In one or more embodiments of the present invention, a first filter screen is installed on the top wall of the first partition, and the first filter screen is used to filter suspended matter in the liquid;

[0018] The height of the first partition and the first filter is greater than the height of the second partition. When the liquid in the second compartment pool is discharged through the second partition, the liquid in the first compartment pool still passes through the first filter to enter the second compartment pool, thereby ensuring the filtering effect of the first filter on the liquid.

[0019] A second filter is connected between the end of the first filter and the side wall of the second partition, and a third filter is connected between the second partition and the top wall of the storage tank body. Both the second filter and the third filter are used to filter suspended matter in the liquid.

[0020] In one or more embodiments of the present invention, a straight pipe is installed on the top wall of the first compartment pool, a plurality of nozzles are installed on the straight pipe, a cleaning pipe is connected to the straight pipe, and the cleaning pipe passes through the main body of the regulating tank. When the cleaning pipe is connected to the clean water supply end, the clean water can enter the straight pipe and be sprayed toward the first compartment pool through the nozzle to clean the dirt on the bottom of the first compartment pool.

[0021] In one or more embodiments of the present invention, the length of the column is less than the height of the first partition plate, and is used to limit the floating height of the suspension plate to ensure that part of the liquid in the first compartment pool can enter the mounting platform and the tapered groove;

[0022] The side wall of the column is fixedly connected to a first support ring for supporting the suspension plate. When there is no liquid in the first compartment pool, the suspension plate contacts the first support ring, and the bristles can contact the bottom wall of the first compartment pool, so that the bristles can be used to clean the bottom of the first compartment pool.

[0023] The top wall of the column is fixedly connected with a first limiting column for limiting the suspension board to prevent the suspension board from completely sliding out of the column.

[0024] In one or more embodiments of the present invention, the suspension capture mechanism includes a suspension plate, a pair of buoyancy enhancing members and a mounting platform are mounted on the suspension plate, the pair of buoyancy enhancing members are symmetrical about the mounting platform, the suspension plate and the buoyancy enhancing members are capable of suspending the upper side of the liquid, and the mounting platform is used to mount a plurality of capture-type cleaning mechanisms;

[0025] The mounting platform is embedded with a plurality of evenly distributed oscillation columns, each of which corresponds to a plurality of the capture-type cleaning mechanisms, and the oscillation columns are used to accommodate oscillation balls;

[0026] The oscillating column is connected to a guide tube, one end of which passes through the mounting platform and the suspension plate, and the liquid in the conical groove can be discharged through the guide tube;

[0027] The suspension plate and the mounting platform are both provided with mutually communicating channels, and the liquid in the first compartment pool can enter between the mounting platform and the cover plate through the channels.

[0028] In one or more embodiments of the present invention, the capture-type cleaning mechanism includes a universal ball, and a rotation groove matching the universal ball is provided in the suspension plate, so that when the oscillating ball is impacted by the liquid, it can move irregularly under the action of the universal ball;

[0029] The universal ball is fixedly connected to a mounting post and a connecting post, one end of the mounting post passes through the suspension plate, and a plurality of bristles are staggeredly connected to the side wall of the mounting post, and the bristles are arranged on the lower side of the suspension plate. When the oscillating ball moves irregularly, the mounting post and the bristles are driven to swing irregularly through the connecting post and the universal ball. The irregularly swinging bristles can capture suspended matter in the liquid and are also used to clean the dirt at the bottom of the first compartment pool.

[0030] In one or more embodiments of the present invention, one end of the connecting column is arranged in the oscillation column, and the end of the connecting column away from the universal ball is connected to the oscillation ball. A conical groove matching the oscillation ball is provided in the oscillation column. When the liquid flows in the conical groove, the liquid can impact the oscillation ball and cause the oscillation ball to move irregularly.

[0031] In one or more embodiments of the present invention, the auxiliary capture mechanism includes a cover plate, the cover plate covers the mounting platform, and the cover plate is capable of capturing suspended matter in the liquid;

[0032] The cover plate is connected to a telescopic belt, and a plurality of leakage holes are provided on the side wall of the telescopic belt. When the cover plate is away from the mounting platform, the telescopic belt is pulled and stretched, and the diameter of the leakage holes becomes larger. The liquid between the mounting platform and the cover plate can be discharged through the leakage holes, while the suspended matter with larger particle size is intercepted by the cover plate.

[0033] The telescopic belt is connected to a fixing ring, which surrounds the mounting platform and is fixedly connected to the suspension plate, and is used to fix the cover plate and the telescopic belt to the outside of the mounting platform;

[0034] The top wall of the cover plate is provided with a plurality of through holes, through which the liquid in the mounting platform can be discharged, and at the same time, the cleaning water can enter the mounting platform through the through holes.

[0035] A method for using the overflow sewage storage device comprises the following steps:

[0036] S1. During rainfall, the initial rainwater, dirt in the upstream pipeline, and pollutants in the atmosphere and the surface enter the first compartment tank through the liquid inlet pipe;

[0037] S2. If it continues to rain, the water level in the first compartment gradually increases, and the suspended plate floats up along the columns and always floats on the upper side of the liquid;

[0038] S3. When the suspension plate moves to the end of the column, it stops rising. Some of the liquid in the first compartment pool flows through the channel into the space between the mounting platform and the cover plate. The cover plate is impacted by the liquid and moves away from the mounting platform. At this time, the expansion belt is pulled and stretched, and the diameter of the leakage hole increases. The liquid between the mounting platform and the cover plate is discharged through the leakage hole and the through hole respectively.

[0039] S4. Some of the liquid in the first compartment pool will also enter the conical groove through the guide tube and impact the oscillating ball. Under the action of the connecting column and the universal ball, the oscillating ball moves randomly in the conical groove. The irregular movement of the oscillating ball drives the mounting column and the brush bristles to swing randomly on the lower side of the suspension plate. The irregular swinging of the brush bristles can capture suspended matter and pollutants in the liquid. At the same time, because the suspension plate floats on the upper side of the first compartment pool, the suspension plate can also block suspended matter in the liquid.

[0040] S5. When the liquid level in the first compartment tank exceeds the first partition plate, the liquid passes through the first filter screen and enters the second compartment tank, where the first filter screen is used to further filter out suspended solids in the liquid.

[0041] S6. When the liquid level in the second compartment tank exceeds the second partition, the liquid passes through the third filter screen and enters the third compartment tank. The second and third filter screens are used to continue filtering suspended solids in the liquid. Finally, the liquid in the third compartment tank enters the sewage treatment plant through the drain pipe.

[0042] S7. If the rainfall stops, the liquid in the first compartment tank, the second compartment tank, and the third compartment tank is discharged through the sewage pipe and introduced into the sewage treatment plant through the sewage pipe;

[0043] S8. When the bottom of the first compartment pool needs to be cleaned, the cleaning pipe is connected to the clean water supply end, and the clean water is sprayed toward the first compartment pool through the nozzle on the straight pipe. Part of the clean water sprayed by the nozzle will directly fall to the bottom of the first compartment pool, and part of the clean water will enter between the mounting platform and the cover plate through the through hole;

[0044] S9. Part of the clean water in the installation table is directly discharged to the bottom of the first compartment pool through the channel, and part of the clean water enters the conical groove and impacts the oscillating ball, thereby causing the installation column and the brush bristles to swing irregularly. The irregularly swinging bristles can clean the dirt at the bottom of the first compartment pool. The dirt and sewage at the bottom of the first compartment pool can be discharged through the sewage pipe and introduced into the sewage treatment plant.

[0045] Compared with the prior art, the overflow sewage storage equipment and the method of use thereof of the present invention can greatly improve the storage capacity of the storage tank, and can effectively treat the sewage entering the storage tank to reduce the overload impact of the sewage treatment plant, thereby solving the problem of overload operation of the sewage treatment plant. At the same time, it can also realize the convenient cleaning of the sewage at the bottom of the storage tank, avoiding the impact of the sewage at the bottom of the tank on the water storage tank.

DETAILED DESCRIPTION

[0064] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0065] like Figures 1 to 15 As shown, an overflow sewage storage device in one embodiment of the present invention includes a storage tank body 1, multiple columns 2, a suspended capture mechanism 3, multiple capture cleaning mechanisms 4 and an auxiliary capture mechanism 5.

[0066] During rainfall, the suspension capture mechanism 3 is suspended on the liquid surface of the first compartment tank, and the suspension capture mechanism 3, the capture cleaning mechanism 4 and the auxiliary capture mechanism 5 can intercept the suspended matter and pollutants in the first compartment tank, so as to reduce the suspended matter and pollutants from continuing to flow to the second compartment tank, the third compartment tank or the sewage treatment plant, thereby reducing the burden on the sewage treatment plant. Figure 12 Schematic diagram of liquid flow shown.

[0067] At the same time, at the beginning of rainfall, rainwater, dirt in the upstream pipeline, and pollutants in the atmosphere and the ground will first enter the first compartment pool through the liquid inlet pipe 103, making the dirt at the bottom of the first compartment pool relatively large. Therefore, when it is necessary to clean the bottom of the first compartment pool, the liquid in the first compartment pool is drained through the sewage pipe 108, so that the suspended capture mechanism 3 descends to the bottom of the column 2. At this time, the capture cleaning mechanism 4 can contact the bottom of the first compartment pool. Then, clean water is injected through the straight pipe 109, and the bottom of the first compartment pool can be cleaned in conjunction with multiple capture cleaning mechanisms 4. Figure 10 Schematic diagram of the cleaning water flow shown.

[0068] like Figures 1 to 15 As shown, a first partition 101 and a second partition 102 are provided within the main body 1 of the regulating and storage tank. The first partition 101 is lower than the second partition 102. A first compartment pool, a second compartment pool, and a third compartment pool are formed between the first and second partitions 101, 102, and the inner wall of the main body 1. The first, second, and third compartment pools are all used to store liquid to achieve rainwater regulation and prevent combined sewer overflow pollution.

[0069] The first and second partitions 101 and 102 are each equipped with a connecting pipe, each equipped with a control valve. The connecting pipes connect the first, second, and third compartments. When the control valves are opened, the liquid in the first, second, and third compartments can flow through each other, allowing the liquid in the first, second, and third compartments to be drained.

[0070] In addition, the main body of the regulating and storage tank 1 is connected to an inlet pipe 103 and a discharge pipe 104. The inlet pipe 103 is connected to the first compartment tank and is connected to the upstream pipeline. The discharge pipe 104 is connected to the third compartment tank and is connected to the sewage treatment plant pipeline. The liquid in the upstream pipeline can enter the regulating and storage tank main body 1 through the inlet pipe 103. The first, second and third compartment tanks in the regulating and storage tank main body 1 are used for regulation and storage to avoid combined sewer overflow pollution. If the regulating and storage tank main body 1 is full of liquid, it will flow to the sewage treatment plant through the discharge pipe 104 to reduce the overload impact on the sewage treatment plant.

[0071] like Figures 1 to 15 As shown, a first filter screen 105 is installed on the top wall of the first partition 101. The first filter screen 105 is used to filter suspended matter in the liquid entering the second compartment tank from the first compartment tank.

[0072] Preferably, the height of the first partition 101 and the first filter screen 105 is greater than the height of the second partition 102. When the liquid in the second compartment pool overflows the second partition 102, the liquid level in the first compartment pool is still at the lower side of the first filter screen 105, that is, the liquid can still be filtered using the first filter screen 105 to remove suspended matter in the liquid.

[0073] A second filter screen 106 is connected between the end of the first filter screen 105 and the side wall of the second partition plate 102, and a third filter screen 107 is connected between the second partition plate 102 and the inner top wall of the storage tank body 1. Both the second filter screen 106 and the third filter screen 107 are used to filter suspended matter from the liquid entering the third compartment tank from the second compartment tank, greatly improving the filtration effect of the liquid and reducing the burden on subsequent sewage treatment plants.

[0074] Preferably, the mesh ratio of the first filter 105, the second filter 106 and the third filter 107 is 1:2:3, which can achieve a progressive filtering effect.

[0075] In another embodiment of the present application, the second filter 106 may not be provided, that is, only the first filter 105 and the third filter 107 are used to filter the suspended matter in the liquid.

[0076] like Figure 1 As shown, a plurality of sewage pipes 108 are installed on the side wall of the regulating and storage tank body 1, and the first compartment tank, the second compartment tank and the third compartment tank are connected to the outside world through the sewage pipes 108 respectively. When the rainfall stops, the liquid in the first compartment tank, the second compartment tank and the third compartment tank can be discharged and introduced into the sewage treatment plant to realize the staggered treatment of the liquid in the regulating and storage tank body 1 by the sewage treatment plant, thereby greatly reducing the load of the sewage treatment plant.

[0077] The top wall of the first compartment is mounted with a straight pipe 109, which is equipped with multiple nozzles. A cleaning pipe is connected to the straight pipe 109 and passes through the main body 1 of the regulating reservoir. During the initial rainfall, rainwater, dirt in the upstream pipeline, and pollutants from the atmosphere and the ground will enter the first compartment through the liquid inlet pipe 103, resulting in a high level of dirt in the first compartment. Naturally, the bottom of the first compartment will also be heavily polluted. Therefore, this application only installs straight pipe 109 in the first compartment to clean the bottom of the first compartment.

[0078] When the bottom of the first compartment pool needs to be cleaned, the liquid in the first compartment pool is drained using the sewage pipe 108, and the suspended capture mechanism 3 will drop to the bottom of the column 2. At this time, the capture cleaning mechanism 4 can contact the bottom of the first compartment pool. When the cleaning pipe is connected to the clean water supply end, the clean water can enter the straight pipe 109 and be sprayed to the first compartment pool through the nozzle. In conjunction with multiple capture cleaning mechanisms 4, the bottom of the first compartment pool can be cleaned to prevent the long-term accumulation of dirt on the bottom of the pool from affecting the normal use of the storage tank body 1. Figure 10 Schematic diagram of the cleaning water flow shown.

[0079] Of course, straight pipes 109 may also be provided in the second compartment pool and the third compartment pool, and a plurality of straight pipes 109 may be connected through connecting pipes to clean the bottoms of the second compartment pool and the third compartment pool.

[0080] like Figures 1 to 15 As shown, a plurality of columns 2 are installed in the first compartment pool, and the columns 2 are used to guide the sliding of the suspended capture mechanism 3.

[0081] Among them, the length of the column 2 is smaller than the height of the first partition 101, and is used to limit the floating height of the suspension capture mechanism 3. When the liquid in the first compartment pool overflows the first partition 101, part of the liquid in the first compartment pool can enter the suspension capture mechanism 3 and trigger the capture cleaning mechanism 4 to swing irregularly. The irregularly swinging capture cleaning mechanism 4 is used to capture suspended matter in the liquid to achieve the purpose of removing suspended matter.

[0082] Preferably, an anti-corrosion layer is provided on the outer side of the column 2 to prevent the column 2 from being corroded by liquid and to increase the service life of the column 2.

[0083] In addition, a first support ring 201 is fixedly connected to the side wall of the column 2 for supporting the suspension plate 301. When there is no liquid in the first compartment pool, the suspension plate 301 contacts the first support ring 201, and the bristles 403 can just contact the bottom wall of the first compartment pool so that the bristles 403 can be used to clean the bottom of the first compartment pool.

[0084] Specifically, a first limiting column 202 is fixedly connected to the top wall of the column 2 to limit the suspension board 301 and prevent the suspension board 301 from completely sliding out of the column 2.

[0085] like Figures 1 to 15 As shown, the suspended capture mechanism 3 is disposed within the first compartmentalized tank and is slidably mounted on a plurality of upright posts 2. The suspended capture mechanism 3 is used to mount a plurality of capture-type cleaning mechanisms 4. Furthermore, when the reservoir body 1 is used to store rainwater, the suspended capture mechanism 3 can float on the liquid surface of the first compartmentalized tank to block large suspended solids.

[0086] The suspension capture mechanism 3 comprises a suspension plate 301, mounted with a pair of floatation members 302 and a mounting platform 303. The floatation members 302 are symmetrical about the mounting platform 303. Both the suspension plate 301 and the floatation members 302 are made of a material that floats on the liquid surface, such as polystyrene. The combination of the suspension plate 301 and the floatation members 302 allows the suspension capture mechanism 3 to float above the liquid, thereby blocking large suspended solids. The mounting platform 303 is used to mount multiple capture cleaning mechanisms 4.

[0087] Preferably, the horizontal cross-sectional area of the suspension plate 301 is smaller than the horizontal cross-sectional area of the first compartment pool. When the suspension capture mechanism 3 floats on the upper side of the liquid in the first compartment pool, the liquid in the first compartment pool can enter the second compartment pool through the gap between the suspension plate 301 and the side wall of the first compartment pool.

[0088] In addition, a plurality of evenly distributed oscillation columns 304 are embedded in the mounting platform 303, and the plurality of oscillation columns 304 respectively correspond to the plurality of capture-type cleaning mechanisms 4. The oscillation columns 304 are used to accommodate the oscillation balls 405. At the same time, the oscillation columns 304 are also used to collect clean water so that the clean water can impact the oscillation balls 405, causing the oscillation balls 405 to move irregularly in the conical groove so that the bristles 403 can clean the bottom of the first compartment pool.

[0089] Specifically, a guide tube 305 is connected to the oscillation column 304, and one end of the guide tube 305 passes through the mounting platform 303 and the suspension plate 301. The liquid in the conical groove and the first compartment pool can communicate with each other through the guide tube 305. At the same time, the clean water in the conical groove can flow to the bristles 403 through the guide tube 305. When the bristles 403 clean the bottom of the first compartment pool, the clean water sprayed by the guide tube 305 can be used to clean the bristles 403.

[0090] In addition, the suspension plate 301 and the mounting platform 303 are both provided with interconnected channels 306 for the flow of liquid and clean water in the first compartment pool.

[0091] Furthermore, a pair of guide posts 307 are fixedly connected to the mounting platform 303 to guide the sliding of the cover plate 501. Second support rings are provided on the sidewalls of the guide posts 307 to support the cover plate 501, allowing it to cover the floating board 301. Second stop posts are provided at the ends of the guide posts 307 to prevent the cover plate 501 from completely sliding off the guide posts 307.

[0092] like Figures 1 to 15As shown, multiple capture-type cleaning mechanisms 4 are installed in the suspended capture mechanism 3. The capture-type cleaning mechanism 4 can swing irregularly under the impact of liquid or clean water so as to capture suspended matter in the liquid. At the same time, when the capture-type cleaning mechanism 4 contacts the bottom of the first compartment pool, it can also clean the dirt on the bottom of the pool.

[0093] The capture cleaning mechanism 4 includes a universal ball 401, and a rotation groove matching the universal ball 401 is provided in the suspension plate 301. When the oscillating ball 405 is impacted by the liquid, it can perform irregular motion under the action of the universal ball 401.

[0094] Furthermore, a mounting post 402 and a connecting post 404 are fixedly connected to the universal ball 401. One end of the mounting post 402 passes through the suspension plate 301. Multiple bristles 403 are staggeredly connected to the sidewall of the mounting post 402. The bristles 403 are located on the underside of the suspension plate 301. When the oscillating ball 405 moves irregularly, the connecting post 404 and the universal ball 401 drive the mounting post 402 and the bristles 403 to oscillate irregularly. The irregularly oscillating bristles 403 can capture suspended matter in the liquid and, when the bristles 403 come into contact with the bottom of the first compartment pool, can also clean dirt from the bottom of the first compartment pool.

[0095] Specifically, a plurality of barbs 4031 are provided on the surface of the bristles 403, which increase the effect of the bristles 403 on capturing suspended matter and can improve the effect of the bristles 403 on cleaning dirt on the bottom of the first compartment pool.

[0096] like Figures 5 to 15 As shown, one end of the connecting post 404 is disposed within the oscillating post 304. The end of the connecting post 404 away from the universal ball 401 is connected to an oscillating ball 405. A conical groove is provided within the oscillating post 304 to match the oscillating ball 405. When liquid or water flows within the conical groove, it impacts the oscillating ball 405, causing it to move irregularly.

[0097] The oscillating ball 405 is connected to a floating belt 406, which is provided with a plurality of interlayers 4061, and a plurality of activated carbon balls 4062 are provided in the interlayers 4061. When the regulating reservoir body 1 is regulating, liquid will enter between the mounting platform 303 and the cover plate 501 and impact the oscillating ball 405, causing the oscillating ball 405 to move irregularly. The floating belt 406 can also follow the oscillating ball 405 and swing irregularly in the liquid. The activated carbon balls 4062 in the interlayers 4061 can absorb particulate matter or harmful substances, thereby improving the sewage treatment capacity of the regulating reservoir body 1 and reducing the treatment burden of the sewage treatment plant. Figure 12 Schematic diagram of liquid flow shown.

[0098] like Figures 1 to 15As shown, the auxiliary capturing mechanism 5 is installed on the suspended capturing mechanism 3 and covers the capturing cleaning mechanism 4. The auxiliary capturing mechanism 5 can also capture suspended matter.

[0099] The auxiliary capturing mechanism 5 includes a cover plate 501 , which covers the mounting platform 303 . When liquid enters between the mounting platform 303 and the cover plate 501 , the cover plate 501 can capture suspended matter in the liquid.

[0100] Furthermore, the cover plate 501 is connected to an expansion strap 502, the sidewalls of which are provided with a plurality of leakage holes 5021. When the cover plate 501 is moved away from the mounting platform 303, the expansion strap 502 is pulled and extended, causing the leakage holes 5021 to expand in diameter. Liquid between the mounting platform 303 and the cover plate 501 can be discharged through the leakage holes 5021, while larger suspended matter is trapped by the cover plate 501, thereby capturing the suspended matter.

[0101] Specifically, a fixing ring 503 is connected to the expansion belt 502 . The fixing ring 503 surrounds the mounting platform 303 and is fixedly connected to the suspension plate 301 , so as to fix the cover plate 501 and the expansion belt 502 to the outside of the mounting platform 303 .

[0102] In addition, a pair of connecting ears 504 are connected to the side walls of the cover 501, and the pair of connecting ears 504 are respectively slidably arranged on a pair of guide columns 307. The connecting ears 504 are arranged between the second support ring and the second limiting column. By sliding the connecting ears 504 on the guide columns 307, the smooth sliding effect of the cover 501 can be ensured.

[0103] Furthermore, the top wall of the cover plate 501 is provided with a plurality of through holes 505, and the liquid between the mounting platform 303 and the cover plate 501 can also be discharged through the through holes 505 to ensure the rainwater storage effect. At the same time, when cleaning the bottom of the first compartment pool, the cleaning water can enter between the mounting platform 303 and the cover plate 501 through the through holes 505, and enter into the oscillation column 304 to impact the oscillation ball 405, causing the oscillation ball 405 to swing irregularly.

[0104] Preferably, the through hole 505 is a trumpet hole, and the diameter of the channel 306 is larger than the minimum diameter of the leak hole 5021 and the through hole 505 , so that liquid suspension entering between the mounting platform 303 and the cover plate 501 can be intercepted by the cover plate 501 and the elastic band 502 .

[0105] A method for using overflow sewage storage equipment comprises the following steps:

[0106] S1. During rainfall, initial rainwater, dirt in the upstream pipeline, and pollutants in the atmosphere and the ground enter the first compartment tank through the liquid inlet pipe 103;

[0107] S2. If the outside continues to rain, the water level in the first compartment pool gradually increases, and the suspension plate 301 floats up along the column 2 and always floats on the upper side of the liquid;

[0108] S3. When the suspension plate 301 moves to the end of the column 2, the suspension plate 301 stops rising. Some of the liquid in the first compartment pool flows through the channel 306 into the space between the mounting platform 303 and the cover plate 501. The cover plate 501 is impacted by the liquid and moves away from the mounting platform 303. At this time, the expansion belt 502 is pulled and stretched, and the diameter of the leakage hole 5021 increases. The liquid between the mounting platform 303 and the cover plate 501 is discharged through the leakage hole 5021 and the through hole 505 respectively.

[0109] S4. Part of the liquid in the first compartment pool will also enter the conical groove through the guide tube 305 and impact the oscillating ball 405. The oscillating ball 405 moves irregularly in the conical groove under the action of the connecting column 404 and the universal ball 401. The irregularly moving oscillating ball 405 drives the mounting column 402 and the bristles 403 to swing irregularly on the lower side of the suspension plate 301, and drives the floating belt 406 to swing irregularly between the mounting platform 303 and the cover plate 501. Figure 12 As shown in the liquid flow diagram, the randomly oscillating bristles 403 can capture suspended matter and pollutants in the liquid below the floating plate 301. The activated carbon balls 4062 in the randomly oscillating floating belt 406 can absorb smaller particles and harmful substances between the mounting platform 303 and the cover plate 501. At the same time, since the floating plate 301 floats on the upper side of the first compartment pool, the floating plate 301 can also block large suspended matter in the liquid.

[0110] S5. When the liquid level in the first compartment pool exceeds the first partition 101, the liquid passes through the first filter 105 and enters the second compartment pool, where the first filter 105 is used to further filter out suspended solids in the liquid.

[0111] S6. When the liquid level in the second compartment pool exceeds the second partition 102, the liquid enters the third compartment pool through the third filter screen 107. The second filter screen 106 and the third filter screen 107 can continue to filter the suspended matter in the liquid. Finally, the liquid in the third compartment pool enters the sewage treatment plant through the drain pipe 104. The first compartment pool, the second compartment pool, and the third compartment pool in the storage tank body 1 are used to store rainwater to avoid overflow pollution of the combined sewer system.

[0112] S7. If the rainfall stops, the liquid in the first compartment tank, the second compartment tank, and the third compartment tank are discharged through the sewage pipe 108 and introduced into the sewage treatment plant through the sewage pipe 108, so as to achieve staggered treatment of the liquid in the regulating reservoir body 1 by the sewage treatment plant, thereby greatly reducing the load of the sewage treatment plant;

[0113] S8. When the bottom of the first compartment pool needs to be cleaned, the liquid in the first compartment pool is drained through the drain pipe 108. The suspended capture mechanism 3 descends to the bottom of the column 2. At this time, the capture cleaning mechanism 4 can contact the bottom of the first compartment pool. The cleaning pipe is connected to the clean water supply end. Clean water is sprayed to the first compartment pool through the nozzle on the straight pipe 109. Part of the clean water sprayed by the nozzle will directly fall to the bottom of the first compartment pool, and part of the clean water will enter between the mounting platform 303 and the cover plate 501 through the through hole 505.

[0114] S9, part of the clean water between the mounting platform 303 and the cover plate 501 is directly discharged to the bottom of the first compartment pool through the channel 306, and part of the clean water enters the conical groove and impacts the oscillating ball 405, thereby causing the mounting column 402 and the bristles 403 to swing irregularly, such as Figure 10 As shown in the schematic diagram of the flow of cleaning water, the irregularly oscillating bristles 403 can clean the dirt on the bottom of the first compartment pool, and the clean water in the conical groove flows to the bristles 403 through the guide pipe 305 and cleans the bristles 403;

[0115] S10. After the bottom of the first compartment tank is cleaned, dirt and sewage can be discharged through the sewage pipe 108 and introduced into the sewage treatment plant.
