Description

Technical Field

[0001] The invention relates to the technical field of rainwater collection, in particular to a regional rainwater collection system. Background Art

[0002] A regional rainwater collection system is a system designed and implemented to collect, store, treat and reuse rainwater within a larger area, such as a city or a specific geographical area. Such systems usually involve multiple subsystems to adapt to the characteristics and needs of different regions. The main purpose of a regional rainwater collection system is to manage rainwater resources more effectively, reduce urban waterlogging pressure, increase the recycling rate of water resources, and improve the quality of urban water environment;

[0003] A typical regional rainwater collection system may include the following aspects:

[0004] Catchment area: This is the first step of the system, which defines the source area for rainwater collection, such as open areas such as urban roofs, parks, squares, etc. Rainwater in these areas can be guided to centralized treatment points through specially designed ditches, pipes and other facilities.

[0005] Transportation system: The collected rainwater is transported to treatment facilities or storage locations through underground pipes or other transportation facilities. The transportation system needs to be carefully designed to ensure that the water quality is not polluted again and that the rainwater can be transported to the destination efficiently.

[0006] Treatment system: The collected rainwater needs to go through a series of treatment steps, including preliminary wastewater interception, filtration, disinfection and other procedures to remove impurities and pollutants so that it meets the predetermined usage standards.

[0007] Storage systems: Treated rainwater is stored in large cisterns or underground storage facilities for use when needed. These storage facilities may be built using different materials and technologies to suit different geographic conditions and space constraints.

[0008] Reuse system: Finally, the treated and stored rainwater will be redistributed to various uses, such as green irrigation, public facility water, industrial cooling water, etc. This helps reduce dependence on traditional water resources and promotes the sustainable use of water resources;

[0009] The existing regional rainwater collection system cannot effectively clean impurities in the collected rainwater during use. Plant leaves and algae may exist in the rainwater during the collection process. The equipment in the prior art can only achieve the effect of filtering rainwater, but during long-term use, impurities can easily clog related filtering components, and thus the normal operation of the rainwater collection system cannot be guaranteed.

[0043] Regional rainwater collection systems, including catchment areas, conveyance systems, treatment systems, storage systems, and recycling systems;

[0044] The water collection area includes a plurality of water collection tanks arranged on the top of a high-rise residential building;

[0048] Preferably, the treatment system comprises a treatment tank 1 connected to the conveying system and the storage system respectively;

[0049] The right end surface of the treatment pool 1 is fixedly connected to a water inlet 2 near the upper side, and the water inlet 2 is connected to the water pump assembly of the delivery system through a pipeline. The left end surface of the treatment pool 1 is fixedly connected to a drain near the lower side, and the drain is connected to the storage tank in the storage system through a pipeline. The drain and the water inlet 2 are both built-in electromagnetic valves;

[0050] A filter plate 4 is movably connected inside the treatment pool 1 .

[0051] Specifically, the left end surface of the treatment pool 1 is integrally connected with a collecting box 3 near the upper side, and a cleaning assembly 5 is arranged in the collecting box 3, the scraper 6 is slidably connected to the right side of the upper end surface of the filter plate 4, and the front and rear sides of the lower end surface of the scraper 6 are slidably connected to the filter plate 4 through a slider and a slide groove, the slider is fixed on the scraper 6, the slide groove is opened on the surface of the filter plate 4, and a reset spring 43 is symmetrically fixedly connected between the right end surface of the scraper 6 and the filter plate 4.

[0052] Specifically, the filter plate 4 has an internal hollow structure design to form a movable groove 41, and a partition 44 is vertically fixed in the middle position of the movable groove 41, and the front and rear sides of the partition 44 are movably connected with sealing plates 42, and a spring 43 is fixed between the sealing plate 42 and the partition 44. Filter holes are penetrated at corresponding positions on the filter plate 4 and the sealing plate 42, and the end of the sealing plate 42 away from the partition 44 is a magnetic metal end. The front and rear sides of the filter plate 4 are fitted with the inner wall of the treatment tank 1, and the fitting part is slidably connected by a slide rail 7, and the inner wall of the treatment tank 1 and the corresponding positions of the front and rear sides of the filter plate 4 are built-in with electromagnets.

[0053] By adopting the above technical scheme, the electromagnet on the inner wall of the treatment pool 1 is controlled to magnetically attract the filter plate 4, the position of the filter plate 4 is fixed, and then the filter plate 4 is magnetically attracted while the sealing plate 42 in the movable groove 41 is magnetically attracted and displaced, the filter holes on the sealing plate 42 are misaligned with the filter holes on the filter plate 4, and the upper opening of the treatment pool 1 is sealed to prevent external impurities from entering.

[0054] Specifically, a waste box 31 is screwed to the front and rear sides of the lower end face of the collecting box 3, a reflux hole 10 connected to the interior of the processing tank 1 is provided on the left side of the processing tank 1 and located below the cleaning component 5, and an air bag 8 is glued and fixed around the lower end face of the filter plate 4, and a liquid level sensor 9 is embedded in the upper inner side of the processing tank 1.

[0055] By adopting the above technical scheme, when working, the water pump component in the conveying system will discharge the rainwater collected in the water collection area into the water inlet 2 through the pipe into the treatment tank 1, the electromagnetic valve built in the water inlet 2 is opened, and the valve in the drain is closed, and then the rainwater is concentrated into the treatment tank 1 and falls on the filter plate 4 in the treatment tank 1. At this time, under the action of the bottom air bag 8 and the buoyancy of the rainwater in the treatment tank 1, the filter plate 4 slowly rises through the slide rail 7, and the rainwater impurities are filtered and stay on the surface of the filter plate 4. When the liquid level sensor 9 senses the rainwater level, it opens the drain valve. At this time, the scraper 6 moves to the water inlet 2, and then the scraper 6 moves from right to left along the surface of the filter plate 4 under the jet drive of the water flow at the water inlet 2, scrapes the impurities on the surface of the filter plate 4 and pushes them into the collection box 3. Since the inner diameter of the water inlet 2 and the drain pipe hole is the same, the water intake and discharge are the same, and the water level in the treatment tank 1 remains unchanged at this time.

[0056] Specifically, the cleaning assembly 5 includes a conveying roller 1 52 and a conveying roller 2 53 which are rotatably connected to the inner wall of the collecting box 3, and the outer parts of the conveying rollers 1 52 and 53 are sleeved with a filter belt 51 with a plurality of filter holes on the surface, and the filter belt 51 is made of rubber material, and a feed port is reserved between the filter belt 51 outside the conveying roller 1 52 and the waste box 31, and the feed port corresponds to the upper opening of the waste box 31, and the conveying rollers 1 52, 53 and the filter belt 51 are two groups symmetrically distributed in the collecting box 3, and a conveying shaft 56 is fixed to the rear end of the adjacent conveying rollers 2 53, and the conveying shaft 56 passes through and extends to the inside of the treatment tank 1, and the rear end of the conveying shaft 56 is fixedly connected to a gear 54, and a rack 55 is fixed to the corresponding position between the left end of the filter plate 4 and the two gears 54, and the gear 54 is meshed with the rack 55.

[0057] By adopting the above technical solution, the filter plate 4 drives the rack 55 fixed to the filter plate 4 to move upward during the upward movement. At this time, the rack 55 is engaged with the gear 54, driving the gear 54 to rotate. At this time, the gear 54 drives the two conveying rollers 2 53 to rotate in the opposite direction through the conveying shaft 56, and cooperates with the conveying roller 1 52 to drive the filter belt 51 to rotate, so as to transport impurities on the upper side. Finally, the impurities enter the waste box 31 through the discharge port.

[0058] Working principle: When working, the water pump assembly in the conveying system will collect rainwater from the catchment area through the pipe into the water inlet 2 and discharge it into the treatment tank 1. The electromagnetic valve built into the water inlet 2 is opened, and the valve in the drain is closed. Then the rainwater is concentrated into the treatment tank 1 and falls on the filter plate 4 in the treatment tank 1. At this time, under the action of the bottom air bag 8 and the buoyancy of the rainwater in the treatment tank 1, the filter plate 4 slowly rises through the slide rail 7, and the rainwater impurities are filtered and stay on the surface of the filter plate 4. When the liquid level sensor 9 senses the rainwater level, it opens the drain valve. At this time, the scraper 6 moves to the water inlet 2, and then the scraper 6 moves from right to left along the surface of the filter plate 4 under the jet drive of the water flow from the water inlet 2, scraping the impurities on the surface of the filter plate 4 and pushing them into the collection box 3. Since the inner diameter of the water inlet 2 and the drain pipe hole is the same, the water intake and discharge are the same. At this time, the water level in the treatment tank 1 remains unchanged;

[0059] After the impurities are pushed into the collection box 3, the impurities remain on the surface of the cleaning component 5. At this time, the filter belt 51 further filters the impurities, and the excess water passes through the filter belt 51 and enters the interior of the treatment tank 1 through the backflow hole 10;

[0060] When the filter plate 4 is moving upward, it drives the rack 55 fixed to the filter plate 4 to move upward. At this time, the rack 55 is engaged with the gear 54, driving the gear 54 to rotate. At this time, the gear 54 drives the two conveying rollers 2 53 to rotate in the opposite direction through the conveying shaft 56, and cooperates with the conveying roller 1 52 to drive the filter belt 51 to rotate, so as to transport impurities on the upper side. Finally, the impurities enter the waste box 31 through the discharge port.

[0061] At this time, the electromagnet on the inner wall of the treatment pool 1 is controlled to magnetically attract the filter plate 4 to fix the position of the filter plate 4. Then, while magnetically attracting the filter plate 4, the sealing plate 42 in the movable groove 41 is displaced, and the filter holes on the sealing plate 42 are misaligned with the filter holes on the filter plate 4, thereby sealing the upper opening of the treatment pool 1 to prevent external impurities from entering.

[0062] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
