[0002] At present, water-saving irrigation technology is widely used in greenhouses, soilless cultivation, greening and other occasions because it can achieve benefits such as water saving, land saving and electricity saving. It also recycles rainwater by installing rainwater collection devices, effectively achieving the effect of water saving. In the process of collecting rainwater by rainwater collection devices, filter nets are often used to filter rainwater. However, long-term filtration work will cause the accumulation of silt and impurities on one side of the filter net, thereby reducing the water flow area of ​​the filter net. This will cause a large amount of rainwater to be unable to pass through the filter net quickly during heavy rain, and accumulate in the water inlet pipe, resulting in the phenomenon of rainwater overflowing the water inlet pipe, and then rainwater accumulates next to the collection port.

[0019] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0020] Please refer to 1-3, a water-saving irrigation rainwater collection device, including a coarse filtering mechanism 3, the coarse filtering mechanism 3 includes an impurity separation tube 31, a water inlet pipe 32 and an elastic ring 37, a first fixing ring 35 is fixedly sleeved on the water inlet pipe 32, a plurality of first umbrella ribs 36 are arranged in a circular array on the first fixing ring 35, one end of the first umbrella rib 36 is rotatably arranged on the first fixing ring 35, and the other end of the first umbrella rib 36 is rotatably connected to the elastic ring 37, a sliding ring 39 is slidably arranged on the water inlet pipe 32, and a plurality of second umbrella ribs are arranged in a circular array on the sliding ring 39 38, one end of the second umbrella rib 38 is rotatably connected to the sliding ring 39, and the other end of the second umbrella rib 38 is rotatably connected to the elastic ring 37, the outer sides of the first umbrella rib 36 and the elastic ring 37 are covered with umbrella cloth 34, and the umbrella cloth 34 is sealed with the first fixing ring 35, a second permanent magnet 310 is fixedly sleeved on the water inlet pipe 32, a first permanent magnet 391 is fixedly connected to the top of the sliding ring 39, and the first permanent magnet 391 is attracted to the second permanent magnet 310, and a filter screen 33 is installed on the water inlet pipe 32, and the filter screen 33 is located above the first fixing ring 35.

[0021] Specifically, the top end of the coarse filtering mechanism 3 is fixedly connected to the water collecting bucket 1, and the bottom end of the coarse filtering mechanism 3 is fixedly connected to the impurity accumulation bin 2. The water inlet pipe 32 passes through the impurity separation pipe 31 and then connects to the fine filtering mechanism 4. The fine filtering mechanism 4 is connected to the water storage device 5 through a pipe. The rainwater is collected by the water collecting bucket 1, the impurity accumulation bin 2 is used for impurity collection, the coarse filtering mechanism 3 and the fine filtering mechanism 4 purify the rainwater, and the treated rainwater is stored in the water storage device 5. The water collecting bucket 1, the impurity accumulation bin 2, the coarse filtering mechanism 3, the fine filtering mechanism 4, and the water storage device 5 can be installed below the ground surface or on the ground. The utility model props up the elastic ring 37 through the first umbrella rib 36 and the elastic ring 37, so that the umbrella cloth 34 outside the elastic ring 37 is pressed against the inner wall of the impurity separation pipe 31, so that the impurities intercepted by the filter net 33 are stored on the upper side of the umbrella cloth 34. As the impurities on the umbrella cloth 34 reach a certain weight, the magnetic attraction between the first permanent magnet 391 and the second permanent magnet 310 is overcome. At this time, the sliding ring 39 slides downward along the water inlet pipe 32, so that the elastic ring 37 no longer abuts the umbrella cloth 34 against the inner wall of the impurity separation tube 31, and the impurities on the umbrella cloth 34 are poured down. After being washed by rainwater, the impurities on the filter screen 33 and the umbrella cloth 34 are also taken away, which solves the problem of impurity accumulation blocking the filter screen 33 and achieves the effect of automatic cleaning. As the impurities are poured into the impurity accumulation bin 2, there is no force on the umbrella cloth 34 at this time. The suction force between the second permanent magnet 310 and the first permanent magnet 391 causes the sliding ring 39 to slide upward on the water inlet pipe 32 and finally adsorbed by the second permanent magnet 310, so that the elastic ring 37 once again abuts the sliding ring 39 against the inner wall of the impurity separation tube 31.

[0022] Furthermore, the elastic ring 37 includes ring blocks 371 , and the ring blocks 371 correspond to the first rib 36 and the second rib 38 one by one. Adjacent ring blocks 371 are fixedly connected by elastic bands 372 .

[0023] Specifically, refer to Figure 3 The umbrella cloth 34 and the circular ring block 371 are connected by a thin line, and a certain distance is reserved for relative sliding. The circular ring block 371 serves as a rotating base for the second umbrella rib 38 and the first umbrella rib 36. The elastic band 372 is made of soft rubber with strong deformation ability. The circular ring block 371 is connected by the elastic band 372, so that the elastic ring 37 can expand and contract as a whole.

[0024] Furthermore, a sealing gasket 311 is fixedly connected inside the impurity separation tube 31 , the outer wall of the sealing gasket 311 is tightly fitted with the inner wall of the impurity separation tube 31 , and the cross section of the sealing gasket 311 is trapezoidal.

[0025] Specifically, refer to Figure 3, a sealing treatment is performed between the sealing gasket 311 and the impurity separation tube 31. When the elastic ring 37 abuts against the sealing gasket 311, as the elastic ring 37 continues to expand, the outer edge of the elastic ring 37 slides upward along the oblique edge of the sealing gasket 311, so that the elastic ring 37 and the sealing gasket 311 are gradually squeezed, so that the umbrella cloth 34 is tightly pressed against the sealing gasket 311 by the elastic ring 37, further improving the sealing between the umbrella cloth 34 and the impurity separation tube 31.

[0026] Furthermore, a second fixing ring 321 is fixedly sleeved on the water inlet pipe 32 , and the second fixing ring 321 is connected to the sliding ring 39 via a return spring 6 , and the return spring 6 is sleeved outside the water inlet pipe 32 .

[0027] Specifically, refer to Figure 3 One end of the return spring 6 is fixedly connected to the bottom end of the sliding ring 39, and the other end of the return spring 6 is fixedly connected to the second fixing ring 321. When the elastic ring 37 presses the umbrella cloth 34 against the sealing gasket 311, the elastic force of the second fixing ring 321 squeezes the sliding ring 39, so that the abutting force between the elastic ring 37 and the sealing gasket 311 is greater, and the sealing performance is better. When the umbrella cloth 34 shrinks, under the elastic force of the return spring 6 and the magnetic attraction of the first permanent magnet 391 and the second permanent magnet 310, the umbrella cloth 34 is quickly propped up and expanded, and is abutted against the sealing gasket 311 again, thereby realizing automatic cleaning of the coarse filtering mechanism 3.

[0028] In this utility model, reference is made to Figures 1 to 3 , rainwater is collected by the water collecting bucket 1, and then filtered through the filter net 33, so that impurities are accumulated on the umbrella cloth 34. When the weight of the impurities reaches a certain weight, the sliding ring 39 disengages from the second permanent magnet 310 and slides downward, driving the umbrella cloth 34 to contract, that is, the impurities are poured into the impurity accumulation bin 2, and then under the elastic force of the reset spring 6 and the magnetic force between the first permanent magnet 391 and the second permanent magnet 310, the umbrella cloth 34 is re-contacted on the sealing pad 311, and this process completes the automatic cleaning of impurities.

[0029] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
