Description

Technical Field

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

[0002] Rainwater harvesting is a sustainable water resource management method that saves water resources and reduces the pressure on urban drainage systems by collecting and utilizing natural precipitation. Some advanced rainwater harvesting systems include multiple stages of water treatment, such as sedimentation, filtration, and disinfection, to ensure that the collected rainwater meets certain water quality standards and can be used for more purposes. When collecting rainwater, it is necessary to treat the rainwater in advance to reduce the pollution of rainwater and prevent the collection device from clogging, which requires a rainwater harvesting device for water treatment.

[0003] However, the patents under the existing technology have the following disadvantages:

[0004] (1) The existing utility model rainwater collection device does not have the function of intercepting and diverting sewage. It only filters out larger debris and garbage through the filter net. However, some sewage mixed with fine dust will flow into the rainwater collection pool through the filter net, resulting in the collected rainwater being too polluted, increasing the difficulty and cost of purification.

[0005] (2) The existing utility model rainwater collection device is not equipped with an anti-backflow component. Some rainwater collection devices are equipped with an interception component. However, when the interception pipe is blocked, the sewage in the interception tank will flow back into the water treatment tank, affecting the cleanliness of the rainwater collection.

[0019] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings, wherein the same parts are represented by the same reference numerals.

[0020] It should be noted that the words "front", "rear", "left", "right", "up" and "down" used in the following description refer to directions in the drawings, and the words "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively.

[0021] In order to make the contents of the present invention more clearly understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0022] like Figures 1 to 3 As shown, a rainwater collection device for water treatment includes a water treatment box 1, which is composed of a box cover assembly 2, a water inlet pipe 3, a rainwater collection pipe 4, a discarded flow pipe 5, a debris collection assembly 6, an anti-backflow assembly 7 and a cut-off assembly 8; the box cover assembly 2 is located at the top of the water treatment box 1, the water inlet pipe 3 is located at one side of the water treatment box 1, the rainwater collection pipe 4 is located at the other side of the water treatment box 1, the discarded flow pipe 5 is located at the bottom of the rainwater collection pipe 4, the debris collection assembly 6 is located on the inner side of the water treatment box 1, the anti-backflow assembly 7 is located on the inner side of the discarded flow pipe 5, and the cut-off assembly 8 is located on the inner side of the water treatment box 1.

[0023] There is a limiting tube 22 at the top of the inner side of the water treatment box 1, a spring 23 is arranged inside the limiting tube 22, a limiting column 24 is arranged at the bottom end of the spring 23, a float 25 is arranged at the bottom end of the limiting column 24, a float 26 is arranged at the bottom end of the float 25, and a sealing hole 27 is arranged inside the water treatment box 1.

[0024] A flow plate 16 is provided on the inner side of the discarded flow pipe 5, a limit tube 17 is provided on one side of the flow plate 16, a spring 18 is provided on the inner side of the limit tube 17, a limit column 19 is provided at one end of the spring 18, a sealing ring 20 is provided on the inner side of the discarded flow pipe 5, and a sealing plate 21 is provided at one end of the limit column 19.

[0025] The water treatment box 1 has a slide groove 9 at the top, a box cover 10 on the inner side of the slide groove 9, a handle 11 on the top of the box cover 10, a placement groove 12 at the inner bottom of the water treatment box 1, a waste box 13 on the inner side of the placement groove 12, a fixing rod 14 on the inner side of the waste box 13, and a filter plate 15 on the inner side of the water treatment box 1.

[0026] In specific use, when it rains, rainwater flows into the water treatment box 1 from the water inlet pipe 3 through the manhole cover, and larger debris such as branches and stones will be retained in the waste box 13 by the filter plate 15. The rainwater containing sediment that has been initially filtered will flow into the discard pipe 5 through the sealing hole 27, and squeeze the sealing plate 21 to shrink, and flow into the wastewater pool through the circulation plate 16. As the rainfall gradually increases, the amount of rainwater flowing into the water treatment box 1 increases, and most of the rainwater mixed with sediment on the ground has flowed into the wastewater pool from the discard pipe 5. The rainwater flowing into the water treatment box 1 gradually becomes clear. As the amount of rainwater flowing into the water treatment box 1 increases, the water level rises, pushing the float 1 25 and the float 2 26 up, and the float 2 26 gradually sticks to the sealing hole 27 and closes the sealing hole 27, closing the discard pipe 5, so that the clearer rainwater flows from the rainwater collection pipe 4 into the rainwater storage tank, completing the interception and diversion collection of rainwater, which is convenient for the subsequent reprocessing of rainwater.

[0027] After the rain stops, hold the handle 11 and slide open the box cover 10, clamp the fixing rod 14 with the tool clamp, pull out the waste box 13 to clean out the waste remaining in the waste box 13, and then reinsert the waste box 13 into the placement slot 12. Cleaning is simple, convenient and quick.

[0028] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
