[0019] A shallow water - permeable storage method, which is applicable to any of the above - mentioned storage devices, and the storage method includes the following steps:

[0020] S1: During rainfall, rainwater passes through the water - permeable paving bricks and enters the shallow storage pool. At this time, the second electric valve is opened and the first electric valve is closed. Pollutants contained in the initial rainwater enter the sewage tank through the sewage discharge pipe, and then the second electric valve is closed and the first electric valve is opened. The water flow in the shallow storage pool enters the purified water tank to collect the rainwater.

[0021] S2: When the dirt in the shallow storage pool accumulates and needs to be cleaned, at this time, the third electric valve and the second electric valve are closed, the first electric valve is opened, and the back - flushing water pump is started. The purified water in the purified water tank flushes the shallow storage pool through the purified water pipe. As the water volume in the shallow storage pool increases, the water below the water - permeable support plate passes through the water - passing holes to drive the rotating rod to rotate, cleaning the dirt attached to the inside of the shallow storage pool.

[0022] S3: After the shallow storage pool is filled with water, the first electric valve is closed, the second electric valve and the third electric valve are opened, and the circulation pump is started. The water flow in the shallow storage pool enters the sewage tank. When the water above the water - permeable support plate passes through the water - passing holes, it will also drive the rotating rod to drive, thereby cleaning the shallow storage pool.

[0023] Advantages of the present invention: When the dirt in the shallow storage tank accumulates to the extent that it needs to be cleaned, start the backwashing water pump. The clean water in the clean water tank is used to backwash the shallow storage tank through the clean water pipe. As the water volume in the shallow storage tank increases, the water below the permeable support plate passes through the water passing holes, and the water flow drives the rotating rod to rotate through the water turbine blades under the guidance of the lower diversion plate, which can wipe and wash the dirt attached to the inner wall of the lower side of the shallow storage tank, the lower surface of the permeable support grille, and the surface of the support member;

[0024] After the shallow storage tank is filled with water, start the circulation pump. The water flow in the shallow storage tank enters the sewage tank. When the water above the permeable support plate passes through the water passing holes, the water flow drives the rotating rod to rotate through the water turbine blades under the guiding action of the upper diversion plate, so as to clean the inside of the shallow storage tank again. The dirt generated by the cleaning flows into the sewage tank. Without disassembling the permeable paving bricks, the storage space module can be automatically cleaned by controlling the opening of the corresponding valves and pumps, which simplifies the cleaning steps of the storage device.

[0039] Embodiment 1

[0040] Refer toFigures 1-6 and Figure 8 , which is an embodiment of the present invention, provides a shallow water - permeable storage device, including: a permeable pavement unit 100, a shallow storage unit 200, a clean water collection unit 300, and a storage and cleaning unit 400.

[0041] Among them, the permeable pavement unit 100 includes a plurality of uniformly arranged permeable pavement bricks 101 and a permeable support grille 102 fixedly laid under the permeable pavement bricks 101;

[0042] Secondly, the shallow storage unit 200 includes a shallow storage tank 201 arranged directly below the permeable support grille 102 and a permeable support plate 202 laid in the shallow storage tank 201. A plurality of groups of uniformly distributed support members 203 are installed between the lower side of the permeable support plate 202 and the inner wall of the lower side of the shallow storage tank 201. Each support member 203 is arranged in a frustum shape, and a reinforcing sleeve 205 is fixedly connected to the side wall of the support member 203. Through the setting of the reinforcing sleeve 205, the overall support strength of the support member 203 for the permeable support plate 202 and the permeable pavement bricks 101 is improved, meeting the upper - layer support requirements of the permeable pavement bricks 101. On one side of each support column close to the permeable support plate 202, a reinforcing rib plate 206 is fixedly connected. The height of the reinforcing rib plate 206 is one - fourth to one - third of the height of the support member 203. The setting of the reinforcing rib plate 203 further improves the connection stability between the permeable support plate 202 and the support member 203, effectively solving the defect that stress concentration is likely to occur at the bending part of the support member 203 and the connection part with the permeable pavement bricks 101, resulting in deformation or even fracture;

[0043] Furthermore, the upper side wall of the permeable support plate 202 is also clamped with the permeable support grille 102 through a plurality of groups of uniformly distributed support members 203. A plurality of groups of uniformly distributed snap rings 103 are fixedly arranged on the permeable support grille 102, and a snap - buckle protrusion 204 matching the snap ring 103 is fixedly arranged at the top of the support member 203. The setting of the snap ring 103 and the snap - buckle protrusion 204 can more conveniently splice the permeable pavement unit 100 and the shallow storage unit 200, facilitating the recycling of the storage device. A plurality of uniformly distributed water - passing holes 207 are opened on the permeable support plate 202, and the positions of the plurality of water - passing holes 207 are staggered from those of the support members 203;

[0044] Further, the clean water collection unit 300 includes a clean water tank 301 arranged on one side of the shallow storage tank 201. The clean water tank 301 is fixedly communicated with the bottom of the shallow storage tank 201 through a clean water pipe 302. A first electric valve 303 is fixedly installed on one side of the clean water pipe 302 close to the shallow storage tank 201. The upper part of one side of the clean water tank 301 is fixedly communicated with a drain pipe 304.

[0045] Further, the storage and cleaning unit 400 includes a backwash water pump 401 fixedly installed at one end of the water purification pipe 302 close to the water purification tank 301. The backwash water pump 401 is usually used in water treatment or filtration systems, mainly for cleaning or flushing equipment such as filters and filter meshes to ensure their long-term effective operation. Its working principle is to use the water flow provided by the pump to backwash the filtration equipment, so that the impurities and sediments in it are washed away, thereby restoring the performance of the filter. Since it is commonly used in real life, the specific model of it is not introduced in detail in the present invention. A sewage tank 402 is fixedly arranged on one side of the shallow storage tank 201 away from the water purification tank 301. The sewage tank 402 is communicated with the shallow storage tank 201 through a sewage discharge pipe, and a second electric valve 403 is fixedly installed on the sewage discharge pipe. In the present invention, the first electric valve 303, the second electric valve 403, and the third electric valve 404b all belong to a kind of electric valve. By driving the actuator with a motor, the valve stem or valve plate of the valve is moved, thereby changing the on-off state or flow rate of the fluid. In the present invention, the above three electric valves can all be remotely controlled and integrated into the intelligent control system. The specific structure and model of them are not introduced in detail in the present invention. Upper guide plates 406 and lower guide plates 407 with staggered positions are respectively fixedly installed at the upper and lower openings of each water passing hole 207. The upper guide plates 406 and the lower guide plates 407 are both arranged in a semicircular shape, and a rotating rod 405 is rotatably installed at the axis of each water passing hole 207. A pair of uniformly distributed bottom scraping rods 409 are fixedly connected to the part of the rotating rod 405 close to the water permeable support plate 202. A plurality of groups of uniformly distributed middle scraping rods 410 are fixedly connected to the side wall of the rotating rod 405, and uniformly distributed top scraping rods 411 are fixedly connected to one end of the rotating rod 405 away from the middle scraping rods 410. A plurality of groups of uniformly distributed water turbine blades 408 are also fixedly connected to the rotating rod 405. The water turbine blades 408 are located between the upper guide plate 406 and the lower guide plate 407.

[0046] Furthermore, rubber branches 414 are fixedly connected to the ends of the bottom scraping rods 409, the middle scraping rods 410, and the top scraping rods 411 away from the rotating rod 405, and the rubber branches 414 are arranged in a Y shape; through the arrangement of the rubber branches 414, the wiping effect of the bottom scraping rods 409, the middle scraping rods 410, and the top scraping rods 411 on the dirt attached to the surface of the support member 203 is increased.

[0047] Further, a bottom brush 412 is fixedly connected to the side of the bottom scraping rod 409 close to the water permeable support plate 202, and a top brush 413 is fixedly connected to the side of the top scraping rod 411 away from the water permeable support plate 202; through the arrangement of the bottom brush 412, the dirt attached to the upper and lower sides of the water permeable support plate 202 can be effectively wiped off, and through the arrangement of the top brush 413, the dirt attached to the water permeable support grille 102 and the bottom of the shallow storage tank 201 can be wiped off.

[0048] Finally, the storage and cleaning unit 400 further includes a purified water recovery component 404, which includes a circulation pipe 404a and a circulation pump 404c fixedly arranged in the sewage tank 402 and communicating with the circulation pipe 404a. Both ends of the circulation pipe 404a are respectively communicated with the sewage tank 402 and the purified water tank 301. A third electric valve 404b is fixedly arranged at one end of the circulation pipe 404a away from the sewage tank 402. Through the arrangement of the circulation pipe 404a, the circulation pump 404c and the third electric valve 404b, the water collected in the sewage tank 402 can be recycled, improving the utilization rate of water resources.

[0049] A shallow water permeable storage method, which is applicable to any of the above storage devices. The storage method includes the following steps:

[0050] S1: During rainfall, rainwater passes through the permeable paving bricks 101 and enters the shallow storage pool 201. At this time, the second electric valve 403 is opened and the first electric valve 303 is closed. The pollutants contained in the initial rainwater enter the sewage tank 402 through the sewage discharge pipe. Then the second electric valve 403 is closed and the first electric valve 303 is opened. The water in the shallow storage pool 201 flows into the purified water tank 301 to collect the rainwater.

[0051] S2: When the dirt in the shallow storage pool 201 needs to be cleaned, the third electric valve 404b and the second electric valve 403 are closed, the first electric valve 303 is opened, and the backflush water pump 401 is started. The purified water in the purified water tank 301 flushes the shallow storage pool 201 through the purified water pipe 302. As the water volume in the shallow storage pool 201 increases, the water below the permeable support plate 202 passes through the water passing holes 207 to drive the rotating rod 405 to rotate, cleaning the dirt attached to the inside of the shallow storage pool 201.

[0052] S3: After the shallow storage pool 201 is filled with water, the first electric valve 303 is closed, the second electric valve 403 and the third electric valve 404b are opened, and the circulation pump 404c is started. The water in the shallow storage pool 201 flows into the sewage tank 402. When the water above the permeable support plate 202 passes through the water passing holes 207, it will also drive the rotating rod 405, thereby cleaning the shallow storage pool 201.

[0053] During use, when the dirt in the shallow storage tank 201 accumulates to the extent that it needs to be cleaned, the third electric valve 404b and the second electric valve 403 are closed at this time, the first electric valve 303 is opened, and the backflush water pump 401 is started. The clean water in the clean water tank 301 flushes the inside of the shallow storage tank 201 through the clean water pipe 302. As the water volume in the shallow storage tank 201 increases, the water below the permeable support plate 202 passes through the water passing holes 207, and the water flow drives the rotating rod 405 to rotate through the water turbine blades 408 under the guiding action of the lower guide plate 407. A variety of scraping rods arranged on the rotating rod 405, rubber branches 414, top brushes 413 and bottom brushes 412 arranged on the scraping rods can wipe and wash the dirt attached to the inner wall of the lower side of the shallow storage tank 201, the lower side of the permeable support grid 102, and the surface of the support member 203;

[0054] S3: After the shallow storage tank 201 is filled with water, the first electric valve 303 is closed, the second electric valve 403 and the third electric valve 404b are opened, and the circulation pump 404c is started. The water flow in the shallow storage tank 201 enters the sewage tank 402. When the water above the permeable support plate 202 passes through the water passing holes 207, the water flow drives the rotating rod 405 to rotate through the water turbine blades 408 under the guiding action of the upper guide plate 406, so as to clean the inside of the shallow storage tank 201 again. The dirt generated by the cleaning flows into the sewage tank 402. Without disassembling the permeable paving bricks 101, the storage space module can be automatically cleaned by controlling the opening of the corresponding valves and pumps, which simplifies the cleaning steps of the storage device.

[0055] Embodiment 2

[0056] Refer to Figure 7 , the difference from Embodiment 1 is that: a fixing frame 415 is threadedly connected to one end of each middle scraping rod 410 away from the rotating rod 405, and a corresponding side brush 416 is fixedly installed on the fixing frame 415; through the setting of the fixing frame 415 and the side brush 416, the wiping effect of the middle scraping rod 410 on the side of the support member 203 is improved, and the fixing frame 415 is connected to the middle scraping rod 410 in a detachable manner, which is convenient for the staff to replace the side brush 416 and ensures that the side brush 416 always maintains the wiping effect on the side of the support member 203.

[0057] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.

A shallow water permeable storage device according to claim 2, characterized in that: The regulating and cleaning unit (400) further comprises a clean water recovery component (404), which comprises a circulation pipe (404a) and a circulation pump (404c) fixedly arranged in the sewage tank (402) and connected to the circulation pipe (404a); both ends of the circulation pipe (404a) are respectively connected to the sewage tank (402) and the clean water tank (301); and a third electric valve (404b) is fixedly arranged at one end of the circulation pipe (404a) away from the sewage tank (402).

7. A shallow water permeable storage device according to claim 1, characterized in that: Each of the support members (203) is configured in a truncated cone shape, and a reinforcing sleeve (205) is fixedly connected to the side wall of the support member (203).

8. A shallow water permeable storage device according to claim 1, characterized in that: A plurality of groups of evenly distributed clamping rings (103) are fixedly arranged on the water-permeable support grid (102), and a buckle protrusion (204) matching the clamping ring (103) is fixedly arranged on the top of the support member (203).

9. A shallow water permeable storage device according to claim 1, characterized in that: A reinforcing rib (206) is fixedly connected to one side of each of the support columns close to the water-permeable support plate (202), and the height of the reinforcing rib (206) is one quarter to one third of the height of the support member (203).

10. A shallow water permeability regulation method, which is applicable to any one of the regulation devices in claims 1 to 9 above, characterized in that: The storage method comprises the following steps: S1: When it rains, rainwater passes through the permeable paving bricks (101) and enters the shallow storage tank (201). At this time, the second electric valve (403) is opened and the first electric valve (303) is closed. Pollutants contained in the initial rainwater enter the sewage tank (402) through the sewage pipe. Then the second electric valve (403) is closed and the first electric valve (303) is opened. The water in the shallow storage tank (201) enters the clean water tank (301) to collect the rainwater. S2: When dirt accumulates in the shallow storage tank (201) and needs to be cleaned, the third electric valve (404b) and the second electric valve (403) are closed, the first electric valve (303) is opened, and the backwash pump (401) is started. The clean water in the clean water tank (301) backwashes the shallow storage tank (201) through the clean water pipe (302). As the amount of water in the shallow storage tank (201) increases, the water below the permeable support plate (202) passes through the water hole (207) to drive the rotating rod (405) to rotate, thereby cleaning the dirt attached to the inside of the shallow storage tank (201); S3: When the shallow storage tank (201) is filled with water, the first electric valve (303) is closed, the second electric valve (403) and the third electric valve (404b) are opened, and the circulation pump (404c) is started. The water in the shallow storage tank (201) flows into the sewage tank (402). When the water above the permeable support plate (202) passes through the water hole (207), it also drives the rotating rod (405), thereby cleaning the shallow storage tank (201).
