Description

Technical Field

[0001] The utility model relates to the technical field of rainwater collection, in particular to a rainwater collection and filtering device. Background Art

[0002] With the increasing severity of urban environmental pollution, rainwater pollution is becoming increasingly serious, especially in the early stages of rainwater, which is rich in pollutants. In some areas, the highest pollutant index of early stages of rainwater is far higher than that of typical urban domestic sewage. Therefore, it is necessary to treat rainwater, especially early stages of rainwater.

[0003] At present, most existing water collection and filtration devices use built-in filter nets to achieve filtration functions. As the usage time increases, the filter nets are easily clogged by garbage. Since rainwater carries various impurities, such as leaves, mud, suspended matter, etc., when passing through the filter net, these impurities will gradually accumulate on the filter net and cause blockage, affecting the normal filtration of rainwater and reducing the filtration efficiency. Utility Model Content

[0007] Furthermore, a plurality of supporting legs are fixedly connected to the bottom outer wall of the filter barrel, and a control screen is fixedly connected to the outer wall of one side of the filter barrel.

[0008] Furthermore, the circumference of the filter screen is fixedly connected with a mounting plate, and both sides of the mounting plate are fixedly connected with second sliders, and the second sliders are slidably plugged into the inner wall of one side of the filter barrel.

[0009] Furthermore, a sliding hole is provided on one side of the second slider, and second sliding grooves are provided on the inner walls on both sides of the sliding hole. A positioning pin is slidably inserted in the sliding hole, and a third slider is integrally formed on both sides of the positioning pin. The third slider is slidably connected to the second sliding groove, and one end of the positioning pin is fixedly connected to a spring, and the other end of the spring is fixedly connected to the inner wall of one end of the sliding hole.

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] Reference Figure 1-Figure 5 , a rainwater collection and filtering device includes a filter barrel 1, the top of the filter barrel 1 is connected to a sealing cover 2 by a hinge, the top of one side of the filter barrel 1 is sealed and plugged with an inlet pipe 5, the other end of the inlet pipe 5 is connected to a valve 6 through a flange, and the bottom of the other side of the filter barrel 1 is plugged with an outlet pipe 11, a filter screen 18 is provided in the filter barrel 1, and the mud, leaves and suspended matter in the rainwater are filtered out by the filter screen 18, a first chute 7 is provided on the inner wall of both sides of the water inlet pipe 5, a first slider 9 is slidably connected in the first chute 7, a telescopic tube 8 is welded between the two first sliders 9, the telescopic tube 8 is slidably plugged into the water inlet pipe 5, and a conical cylinder 10 is fixedly plugged into one end of the telescopic tube 8, and a sealing cover 2 is rotatably connected to a connecting column 12, and a plurality of panels 13 are welded to the circumferential outer wall of the connecting column 12. The telescopic tube 8 can be extended to the panel 13. A plurality of connecting rods 14 are welded to the bottom end of the connecting column 12. A brush 15 is fixed to the bottom of the connecting rod 14 by bolts. The brush 15 contacts the filter 18 and pushes the first slider 9 to move in the first chute 7 under the scouring of rainwater, thereby extending the telescopic tube 8 to the panel 13. Then, the rainwater scouring on the panel 13 drives the panel 13 to rotate, thereby driving the connecting column 12 to rotate, and then driving the brush 15 to brush the filter 18 to avoid clogging the mesh of the filter 18, so as not to affect the collection and filtration of rainwater.

[0024] The bottom outer wall of the filter barrel 1 is fixed with multiple supporting legs 3 by bolts, and the filter barrel 1 is supported by the supporting legs 3. A control panel 4 is fixed to the outer wall of one side of the filter barrel 1 by bolts, and a mounting plate 17 is fixedly connected to the circumference of the filter screen 18. A second slider 19 is welded on both sides of the mounting plate 17, and the second slider 19 is slidably inserted into the inner wall of one side of the filter barrel 1. A sliding hole is provided on one side of the second slider 19, and a second slide groove 20 is provided on the inner walls of both sides of the sliding hole. A positioning pin 22 is slidably inserted in the sliding hole, and a third slider 23 is integrally formed on both sides of the positioning pin 22. The third slider 23 is slidably connected to the second slide groove 20, and one end of the positioning pin 22 is welded with a spring 21, and the other end of the spring 21 is fixedly connected to the inner wall of one end of the sliding hole. Positioning holes 16 are provided on the inner walls of both sides of the filter barrel 1, and the positioning pin 22 is fixedly connected to the inner wall of the sliding hole. The positioning hole 16 is engaged, and the second slider 19 is slid downward along the inner wall of the filter barrel 1, so that the filter screen 18 slides into the filter barrel 1 until the positioning pin 22 is aligned with the positioning hole 16. Under the elastic action of the spring 21, the third slider 23 moves in the second slide groove 20, so that the positioning pin 22 pops out and engages with the positioning hole 16, thereby fixing the filter screen 18. A shift block 24 is welded on the top of the positioning pin 22, and the shift block 24 is provided with an anti-slip groove. The shift block 24 is pulled to retract the positioning pin 22 into the sliding hole, thereby separating the positioning pin 22 from the positioning hole 16, and then the filter screen 18 is taken out of the filter barrel 1, thereby completing the disassembly of the filter screen 18. A handle is fixed to the outer wall of one side of the sealing cover 2 by bolts, and the outer wall of the handle is sleeved with an anti-slip sleeve, which facilitates the opening and closing of the sealing cover 2.

[0025] The working principle of this embodiment is as follows: when in use, first, pull the handle to open the sealing cover 2, then slide the second slider 19 downward along the inner wall of the filter barrel 1, thereby sliding the filter 18 into the filter barrel 1 until the positioning pin 22 is aligned with the positioning hole 16, and the elastic action of the spring 21 causes the third slider 23 to move in the second slide groove 20, so that the positioning pin 22 pops out and engages with the positioning hole 16, thereby fixing the filter 18;

[0026] On rainy days, when the rain is light, the valve 6 is opened, and rainwater flows from the water inlet pipe 5 into the filter barrel 1, wherein the mud, leaves, and suspended matter in the rainwater are intercepted by the filter screen 18 on its surface, and then the rainwater falls on the bottom of the filter barrel 1 to be collected, and finally discharged from the outlet pipe 11. When the rain is heavy, the first slider 9 is pushed to move in the first chute 7 under the scouring of the rainwater, thereby extending the telescopic tube 8 to the panel 13. Then, the rainwater scouring on the panel 13 drives the panel 13 to rotate, thereby driving the connecting column 12 to rotate, and then driving the brush 15 to brush the filter screen 18 to prevent the mesh of the filter screen 18 from being blocked;

[0027] When the filter 18 needs to be disassembled, the shift block 24 is moved to retract the positioning pin 22 into the sliding hole, thereby separating the positioning pin 22 from the positioning hole 16 , and then the filter 18 can be taken out of the filter barrel 1 .

[0028] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
