Description

Technical Field

[0001] This utility model relates to the field of rainwater treatment technology, specifically to an integrated device for initial rainwater collection, storage, and treatment. Background Technology

[0002] During rainfall, urban rainwater flows out from paved surfaces such as buildings, roads, and parking lots, washing away pollutants like dust, oil, and garbage into drainage systems. This pollutants then enter rivers, lakes, and other water bodies, causing urban non-point source pollution, a phenomenon particularly common in heavily urbanized areas. Many cities have now implemented rainwater harvesting and management systems, using purification processes to remove pollutants and converting treated rainwater into recycled water for purposes such as green space irrigation and road cleaning. This reduces water pollution loads and enhances the city's ability to cope with extreme rainfall.

[0003] In existing urban rainwater harvesting and management systems, storage tanks are often divided into rainwater tanks and clear water tanks. A filtration system filters the rainwater in the rainwater tanks before transferring it to the clear water tanks for storage. However, over long-term use, the filtration system is prone to clogging by impurities, and is difficult to clean and maintain when malfunctions occur. Furthermore, the impurities deposited at the bottom of the rainwater tanks are also difficult to remove. Utility Model Content

[0004] To address the aforementioned shortcomings of existing technologies, an integrated device for initial rainwater collection, regulation, and treatment is provided. This device can clean impurities accumulated on the filter screen, collect and treat the impurities in a unified manner, and facilitate replacement when the filter screen malfunctions.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: An integrated device for initial rainwater collection, storage, and treatment includes a water storage tank, a filtration mechanism, a cleaning mechanism, and a collection mechanism; The bottom plate of the water storage tank is provided with a partition, and the two ends of the partition are fixedly connected to the front side plate and the rear side plate of the water storage tank respectively. The top of the water storage tank is provided with a top plate, and the top plate is fixedly connected to the front side plate, the rear side plate and the left side plate of the water storage tank respectively. An inlet for rainwater to enter is left between the top plate and the right side plate of the water storage tank. The top plate has a horizontal slot, the front and rear side plates of the water tank have vertical grooves on their inner walls, and the top of the partition has a horizontal groove. The slots, vertical grooves and horizontal grooves are located in the same vertical plane. The filter mechanism is detachably inserted into the slots, vertical grooves and horizontal grooves. The filter mechanism and the partition divide the inner cavity of the water tank into a clear water chamber and a raw water chamber. The cleaning mechanism is located on the top plate and extends into the raw water chamber to clean impurities on the filtration mechanism. The partition has an inclined surface on one side of the raw water chamber. The collection mechanism is detachably located at the bottom of the raw water chamber.

[0010] According to the above technical solution, a second limiting piece is also fixed on the support rod, and the second limiting piece is located between the brush plate and the top plate.

[0011] According to the above technical solution, the collection mechanism includes a collection box, which is embedded in the cavity formed by the front side plate, the rear side plate, the partition and the right side plate. The top of the collection box has a sloping opening around its perimeter, and the angle of the sloping opening is the same as the angle of the inclined surface of the partition.

[0012] According to the above technical solution, the size of the collection box is smaller than the size of the water inlet, and a pull rod is detachably provided on the bottom of the inner wall of the collection box.

[0013] According to the above technical solution, the collection box is made of a water-permeable material.

[0014] According to the above technical solution, a drain outlet is provided on the left side plate of the water storage tank, and a valve is provided on the drain outlet.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0022] Reference Figures 1-4 The present invention provides an integrated device for initial rainwater collection, storage and treatment.

[0023] Example 1 The system includes a water storage tank 1, a filtration mechanism 3, a cleaning mechanism 4, and a collection mechanism 5. A partition 11 is provided on the bottom plate of the water storage tank 1, with both ends of the partition 11 fixedly connected to the front side plate 12 and the rear side plate 13 of the water storage tank 1, respectively. A top plate 16 is provided on the top of the water storage tank 1, and the top plate 16 is fixedly connected to the front side plate 12, the rear side plate 13, and the left side plate 14 of the water storage tank 1, respectively. An inlet 6 for rainwater to enter is provided between the top plate 16 and the right side plate 15 of the water storage tank 1. A horizontal slot 2 is provided on the top plate 16. Vertical grooves 21 are provided on the inner walls of both the front side plate 12 and the rear side plate 13 of the water storage tank 1, and a horizontal groove 22 is provided on the top of the partition 11. Slot 2, vertical slot 21 and horizontal slot 22 are located in the same vertical plane. The filter mechanism 3 is detachably inserted into slot 2, vertical slot 21 and horizontal slot 22. The filter mechanism 3 and partition 11 divide the inner cavity of the water storage tank 1 into a clear water chamber 23 and a raw water chamber 24. The cleaning mechanism 4 is located on the top plate 16 and extends into the raw water chamber 24 to clean impurities on the filter mechanism 3. The partition 11 has an inclined surface 111 on one side inside the raw water chamber 24. The collection mechanism 5 is detachably located at the bottom of the raw water chamber 24. After the impurities are cleaned off the filter mechanism 3, they fall into the collection mechanism 5 through the inclined surface 111 for storage.

[0024] In this embodiment, the filtration mechanism 3 includes a filter frame 31, which is rectangular in structure. The bottom of the filter frame 31 is inserted into the horizontal groove 22 at the top of the partition 11, and the two sides of the filter frame 31 are respectively inserted into the vertical grooves 21 on the inner walls of the front side plate 12 and the rear side plate 13. The top of the filter frame 31 is inserted into the slot 2 of the top plate 16. The filter frame 31 and the partition 11 divide the inner cavity of the water storage tank 1 into a clear water chamber 23 and a raw water chamber 24. A filter screen 32 is provided inside the filter frame 31, and a handle 33 is fixed to the top of the filter frame 31. The filter frame 31 can be pulled out from the slot 2, the vertical groove 21 and the horizontal groove 22 through the handle 33, which is convenient for maintenance or replacement of the filter screen 32. Both sides of the filter frame 31 are provided with elastic gaskets 34. The gaskets 34 are preferably made of rubber and are strip-shaped. They are arranged around the edge of the filter frame 31 to increase the sealing between the filter frame 31 and the slot 2, vertical slot 21 and horizontal slot 22, and prevent unfiltered rainwater from flowing from the raw water chamber 24 into the clear water chamber 23.

[0025] In this embodiment, the partition 11 has an inclined surface 111 on one side inside the raw water chamber 24, and the inclined surface 111 is connected to the surface of the filter frame 31. The collection mechanism 5 includes a collection box 51, which is embedded in the cavity formed by the front side plate 12, the rear side plate 13, the partition 11, and the right side plate 15. The top of the collection box 51 has a sloping opening 52 around its perimeter, and the angle of the sloping opening 52 is the same as the angle of the inclined surface 111 of the partition 11, so that impurities can fall into the collection box 51 along the inclined surface 111 of the partition 11.

[0026] In this embodiment, the collection box 51 is made of a water-permeable material and its size is smaller than that of the inlet 6. A pull rod 53 is detachably provided on the bottom of the inner wall of the collection box 51, and the pull rod 53 is fixedly connected to the collection box 51 by threads. When it is necessary to clean the collection box 51, lift the pull rod 53 to make the collection box 51 slide upward between the front side plate 12, the rear side plate 13, the partition plate 11 and the right side plate 15. The rainwater in the collection box 51 seeps out through the wall of the collection box 51, leaving only impurities in the collection box 51. Continue to lift the collection box 51 from the inlet 6 to facilitate direct cleaning and rinsing of the impurities in the collection box 51. After cleaning, the collection box 51 can be reset. This device can easily clean the collection box 51 and avoid long-term accumulation of impurities in the raw water chamber 24, which would lead to water quality deterioration.

[0027] In this embodiment, a drain outlet 7 is provided on the left side plate 14 of the water storage tank 1. A valve 71 is provided on the drain outlet 7. The drain outlet 7 can be connected to a hose to transport the filtered clean rainwater in the clear water chamber 23 to a designated location for purposes such as greening irrigation and road cleaning.

[0028] Example 2 The principle and technical solution of Embodiment 2 are basically the same as those of Embodiment 1, except that a preferred structural form of the cleaning mechanism 4 is given.

[0029] In this embodiment, the cleaning mechanism 4 includes a support rod 41, which movably passes through the top plate 16 and extends into the raw water chamber 24. A first limiting plate 42 is fixed to the top of the support rod 41, and a brush plate 43 is fixed to the bottom of the support rod 41. The brush plate 43 is provided with bristles that are close to the surface of the filter screen 32. A return spring 44 is provided between the first limiting plate 42 and the top plate 16. The return spring 44 is sleeved on the support rod 41, and its two ends are fixedly connected to the first limiting plate 42 and the top plate 16, respectively. In use, pressing the first limiting plate 42 causes the brush plate 43 and the bristles to move downwards via the support rod 41, cleaning the impurities attached to the surface of the filter screen 32. Releasing the first limiting plate 42 causes the return spring 44 to push the first limiting plate 42 upwards, and the first limiting plate 42 causes the brush plate 43 and the bristles to return to their original position via the support rod 41. Repeatedly pressing the first limiting plate 42 can quickly clean the filter screen 32, which is very convenient.

[0030] In this embodiment, a second limiting piece 45 is also fixed on the support rod 41, and the second limiting piece 45 is disposed between the brush plate 43 and the top plate 16. During the process of the reset spring 44 pushing the first limiting piece 42, support rod 41, brush plate 43 and brush bristles to reset, the reset ends when the second limiting piece 45 contacts the bottom surface of the top plate 16. The second limiting piece 45 can prevent the brush plate 43 from directly contacting the top plate 16 during reset, thereby avoiding damage to the brush plate 43 and brush bristles.

[0031] The working process and principle of this utility model are as follows: During use, rainwater is poured into the raw water chamber 24 through the inlet 6. When the water level exceeds the partition 11, the rainwater passes through the filter screen 32 and filter frame 31 and enters the clear water chamber 23. Impurities in the rainwater are filtered by the filter screen 32 and fall off under gravity, flowing down the slope 111 of the partition 11 into the collection box 51. The valve 71 on the drain outlet 7 is then opened to deliver the filtered rainwater from the clear water chamber 23 to the designated location.

[0032] When it is necessary to clean the impurities attached to the surface of the filter screen 32, press the first limiting plate 42. The support rod 41 will drive the brush plate 43 and brush bristles to move downwards. After the impurities on the surface of the filter screen 32 are brushed off by the brush bristles, they will enter the collection box 51 along the inclined surface 111 of the partition 11. After the reset spring 44 is reset, press the first limiting plate 42 again to clean the filter screen 32 quickly and conveniently. When the filter screen 32 malfunctions, lift the filter frame 31 and the filter screen 32 together using the handle 33 for easy maintenance or replacement of the filter screen 32.

[0033] When the collection box 51 needs to be cleaned, lift the lever 53 to remove the entire collection box 51, clean away the accumulated impurities, rinse the collection box 51, and then put the collection box 51 back in its original position. The device can easily clean the collection box 51, keep the raw water chamber 24 clean, and prevent impurities from accumulating in the raw water chamber 24 for a long time, which would lead to water quality deterioration.

[0034] The embodiments described above are some, but not all, embodiments of this utility model. The detailed description of the embodiments of this utility model is not intended to limit the scope of the claimed utility model, but merely to illustrate selected embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
