Description

Technical Field

[0001] The present invention relates to the technical field of rainwater treatment, and in particular to a collection and purification device for rainwater resource utilization in a residential area. Background Art

[0002] China's "Sponge City Construction Guidelines" require that newly built residential communities reuse 30% or more of their rainwater to alleviate the conflict between urban waterlogging and water shortages. Rainwater resource utilization can be achieved by collecting and purifying rainwater for greening irrigation, road cleaning, and other uses, thereby reducing municipal water consumption (a typical residential community can save 3,000 to 5,000 tons of water annually).

[0003] At present, the collection and purification device for rainwater resource utilization in the community has an unreasonable design of the guide plate slope, which leads to rainwater retention (water accumulation rate is >15% when the slope is <2%). At the same time, surface runoff washes pollutants (sediment carrying capacity reaches 50-100 mg / L), causing blockage in the filter layer structure, resulting in low water collection efficiency.

[0004] In the patent document with the publication number CN112681497B, a sponge city seepage and drainage structure and its water circulation system are disclosed, which relates to an urban seepage and drainage system, aiming to solve the problem that the pipes of the water collection port are easily blocked in the prior art. The key points of its technical solution include a water reservoir, a water collection ditch for supplying rainwater to the water reservoir, and at least one drainage ditch for supplying rainwater to the water collection ditch; it uses a filter component to filter debris in the water collection ditch and the drainage ditch. When a lot of debris is filtered, the filter component is disassembled from the water collection ditch and the drainage ditch, and the debris is taken out, so as to reduce the possibility of debris clogging the drainage ditch and the water collection ditch, resulting in the inability to drain water to the water reservoir, which is conducive to reducing the possibility of affecting the water storage in the water reservoir.

[0005] When the above device is in use, the diversion component of the ditch is in a fixed tilted state. When the rain intensity is large, due to the fixed tilt of the diversion component, the flow rate of the guide plate cannot keep up with the falling speed of the rainwater, causing the rainwater to accumulate easily, and the sand settling trough on the surface cannot process the sand accumulated in the rainwater, resulting in poor rainwater collection efficiency.

[0006] Therefore, this application proposes a collection and purification device for the resource utilization of rainwater in residential areas. Summary of the Invention

DETAILED DESCRIPTION

[0035] The technical solution of the present invention is further described below with reference to the accompanying drawings and specific embodiments.

[0036] like Figures 1-8 As shown, the collection and purification device for community rainwater resource utilization proposed by the present invention includes a community rainwater collection component 1, a guide and position-changing component 3 is installed inside the community rainwater collection component 1, and a diversion component 2 is provided on the top of the guide and position-changing component 3 to guide rainwater to a specified position;

[0037] The guide assembly 2 includes a guide plate 201, a support base plate 206 is fixedly installed at the bottom of the guide plate 201, a pressure sensor is fixedly installed between the guide plate 201 and the support base plate 206, a garbage collection assembly 5 is installed on the top of the community rainwater collection assembly 1, and a purification drive assembly 4 is installed on one side of the garbage collection assembly 5 extending to the inside of the community rainwater collection assembly 1. The community rainwater collection assembly 1 includes a community planning land 102, and multiple groups of water collection tanks 101 are opened on the surface of the community planning land 102. Multiple groups of rain-passing plates 103 are plugged into the top of the water collection tank 101. The auxiliary positioning frame 301 is fixedly installed at the bottom of the water collection tank 101. A PE water storage tank with a capacity of 5m is provided on one side of the community rainwater collection assembly 1. 3 -20m 3 , and the rainwater purified by the garbage collection component 5 enters the PE water storage tank through the filtering component for storage, which is convenient for later use.

[0038] Furthermore, the guide shifting assembly 3 includes a hollow slide cavity frame 306 slidably mounted on the outside of the support base plate 206, a concave guide rod 304 is fixedly mounted on the bottom of the hollow slide cavity frame 306, two sets of positioning guide plates 305 are hinged on both sides of the concave guide rod 304, and two sliding ring blocks 303 are hinged on the bottom of the concave guide rod 304. The same number of slide rods 302 are slidably mounted inside the two sliding ring blocks 303, and auxiliary positioning frames 301 are fixedly mounted on both sides of the slide rod 302. The top of the moving ring block 303 is fixedly installed with a long positioning plate 308, and the middle of the long positioning plate 308 is fixedly installed with a hydraulic pushing component 309. The hydraulic pushing component 309 is fixedly installed on the inner wall of the auxiliary positioning frame 301. A retractable guide plate is formed between the auxiliary guide plate 202 and the guide plate 201 to adapt to different rainfall intensities. When rainwater enters the guide plate 201 from the opening of the rain plate 103, it is explained here that the auxiliary guide plate 20 is directly below the opening of the rain plate 103. 2, and the opening of the rain-passing plate 103, that is, the place where the rain falls, is the moving range of the guide plate 201. When the auxiliary guide plate 202 and the guide plate 201 undergo telescopic movement, the rain cannot enter the sliding gap between the two. At the same time, the rain drops onto the guide plate 201, impacting the guide plate 201. The greater the intensity of the rain, the more the guide plate 201 transmits the pressure to the pressure sensor between the support base plate 206. The pressure sensor is connected to the controller, and the controller controls the hydraulic pushing assembly 30 9 works, the hydraulic pushing component 309 drives the long positioning plate 308 to slide along the slide rod 302 toward the direction away from the garbage collection component 5 through the two sliding ring blocks 303, and the sliding ring block 303 drives the concave guide rod 304 to deflect counterclockwise under the limit of the positioning guide plate 305, so that the inclination angle of the guide plate 201 along the horizontal plane becomes larger, and the rainwater can be quickly transmitted along the inclined slope of the guide plate 201, avoiding rainwater retention, and effectively transmitting rainwater according to different rainfall intensities.

[0039] like Figure 3 and Figure 5As shown, the guide assembly 2 also includes an auxiliary guide plate 202 slidably mounted inside the guide plate 201, a first spring 203 is fixedly installed between the auxiliary guide plate 202 and the guide plate 201, a second spring 307 is fixedly installed between the support bottom plate 206 and the hollow slide cavity frame 306, and the guide plate 201 is provided with a plurality of groups of V-shaped sand settling grooves 204 on the side away from the hollow slide cavity frame 306. The surface of the V-shaped sand settling groove 204 is provided with a plurality of limiting arc blocks 205. As the guide plate 201 tilts, the rainwater is discharged by gravity and the tilt direction of the guide plate 201. The rainwater is guided in the V-shaped grit trough 204. Since the V-shaped grit trough 204 is a double-sided V-shaped groove, the rainwater can smoothly slide down from the limiting arc block 205 to the bottom when passing through the limiting arc block 205. The gravel is large in volume, so it is blocked by the surface of the limiting arc block 205 when passing through the limiting arc block 205, which improves the efficiency of rainwater purification and reduces the impact of gravel on the rear filter assembly. When the rain stops, the guide plate 201 returns to its original position, and the limiting arc block 205 places the blocked gravel horizontally, which is convenient for the staff to clean it when removing the rain-passing plate 103.

[0040] In this embodiment, Figure 2 and Figure 9As shown, the garbage collection assembly 5 includes an auxiliary rain collecting rack 505 fixedly mounted on the inner wall of the water collection tank 101, a coarse filter 504 is fixedly mounted on the side of the auxiliary rain collecting rack 505 away from the guide plate 201, the auxiliary guide plate 202 is against the inner wall of the water collection tank 101, the guide plate 201 is against one side of the coarse filter 504, the auxiliary rain collecting rack 505 is arranged below the guide plate 201, when the guide plate 201 is deflected, due to the auxiliary guide plate 202 and the water collection tank 101 seal contact, the two offset, the reaction force of the seal of the rain plate 103 is transmitted to the guide plate 201 through the first spring 203, and the guide plate 201 is in contact with the surface of the coarse filter 504, and the two always offset, then the guide plate 201 is limited by the second spring 307 and slides on the hollow slide frame 306. Since the guide plate 201 and the auxiliary guide plate 202 are always tightly against the coarse filter 504 and the water collection tank 101, 4. The filter screen 504 is a kind of water filter that is convenient to clean and tidy.

[0041] Further, such as Figure 9 and Figure 10As shown, the purification drive assembly 4 includes an openable protective frame 401 fixedly installed on the top of the cell planning site 102, the inner wall of the openable protective frame 401 is fixedly installed with a forward and reverse motor, the output shaft of the forward and reverse motor is fixedly installed with a positioning swivel plate 402, one side of the positioning swivel plate 402 is fixedly installed with a group of auxiliary long rods 407, the outer side of a group of auxiliary long rods 407 is fixedly installed with a first eccentric wheel 408, the number of auxiliary long rods 407 is two groups, the two groups of auxiliary long rods 407 are rotatably installed inside the openable protective frame 401, the outer side of the first eccentric wheel 408 is rotatably installed with a two-way wrapping rod 409, and one side of the other group of auxiliary long rods 407 is fixedly installed with a second eccentric wheel 410, and the second eccentric wheel 410 is rotatably installed. Installed inside the two-way wrapping rod 409, the filter hole of the coarse filter 504 is larger than the filter hole of the filter type garbage collection rack 503. The coarse filter 504 is used to block larger garbage, and the filter type garbage collection rack 503 is an activated carbon filter, which is effective in further purifying rainwater. Two sets of auxiliary long rods 407 pass through one end of the second eccentric wheel 410 and are fixedly installed with corresponding rotating rods 406. Auxiliary limiting plates 405 are rotatably installed at the bottom of the corresponding rotating rods 406. The bottom of the auxiliary limiting plates 405 is fixedly installed with a sliding rod 403. A sliding groove is opened on the surface of the community planning land 102. The sliding rod 403 is slidably installed inside the sliding groove. The sliding rod 403 extends to one side of the inside of the water collection tank 101 and is fixedly installed with a positioning cleaning pressure plate 404. The sliding rod 403 passes through one side of the positioning cleaning pressure plate 404 and is slidably installed with a storage cavity block 502. The bottom of the storage cavity block 502 is fixedly installed with a garbage pushing plate 501. One side of the coarse filter screen 504 is fixedly installed with a filtering garbage collection rack 503. The garbage pushing plate 501 is slidably installed on one side of the filtering garbage collection rack 503. When collecting rainwater normally, the positioning cleaning pressure plate 404 is located on the inner wall at the bottom of the rain-passing plate 103. At this time, when rainwater is filtered through the coarse filter screen 504, rainwater and existing impurities cannot enter the gap between the positioning cleaning pressure plate 404 and the rain-passing plate 103. When rainwater penetrates outward along the rain-passing plate 103, that is, when the rainwater cannot be collected or the staff needs to clean the coarse filter screen 504, the rainwater and existing impurities cannot enter the gap between the positioning cleaning pressure plate 404 and the rain-passing plate 103. 04 and the storage cavity block 502 are maintained, the forward and reverse motors drive the positioning swivel plate 402 to rotate, and the positioning swivel plate 402 drives the first eccentric wheel 408 to rotate, and the first eccentric wheel 408 is an eccentric component. When it rotates, it generates a thrust to the second eccentric wheel 410 through the bidirectional wrapping rod 409. Under the guidance of the thrust, the second eccentric wheel 410, which is also an eccentric component, rotates. The second eccentric wheel 410 and the first eccentric wheel 408 drive the two sets of auxiliary long rods 407 to rotate along the bracket inside the openable protective frame 401. When the auxiliary long rod 407 drives the auxiliary limiting plate 405 to rotate, the auxiliary limiting plate 405 drives the positioning cleaning pressure plate 404 to move downward and toward the filtering garbage collection rack 503.The positioning cleaning pressure plate 404 presses downward against any excess garbage that may have accumulated within the sliding rod 403, compressing the gaps between them and allowing rainwater to flow through. Simultaneously, as the sliding rod 403 slides within the storage cavity 502, it drives the garbage pushing plate 501 along the upper surface of the filtering garbage collection rack 503. The garbage pushing plate 501 carries the garbage away from the coarse filter 504, preventing it from clogging the coarse filter 504 and causing rainwater accumulation. Simultaneously, the downward pressure of the positioning cleaning pressure plate 404 compresses the garbage, improving the efficiency of rainwater purification.
