[0001] The utility model relates to the technical field of rainwater treatment, in particular to a multi-stage overflow well and an ecological wet pond water regulation system. Background Art
[0002] In the rainy season, the converged rainwater will put pressure on the municipal pipe network, especially in mountainous areas.

[0009] Based on the above-mentioned structure of a multi-stage overflow well, the multi-stage overflow structure includes a water baffle and an overflow hole. The overflow hole is located at the center position along the width direction of the water baffle, and the overflow holes are evenly spaced along the length direction of the water baffle. The water baffle is connected to the opening of the water filter chamber by bolts; the first-stage overflow hole is a predetermined distance from the bottom of the water baffle, and the last-stage overflow hole is a predetermined distance from the top of the water baffle.

[0029] Example 1
[0030] like Figures 1 to 4 As shown, the utility model provides a technical solution:
[0031] A multi-stage overflow well, which at least includes but is not limited to a support body 1, a filter part and a water outlet part 2; a water filter chamber 3 is provided inside the support body 1, the water outlet part 2 is connected to the water filter chamber 3, the top and one side wall of the water filter chamber 3 are opened, the support body 1 is provided with an opening matching the side wall of the water filter chamber 3, the filter part is respectively provided at the top position of the filter chamber and the side wall opening position of the support body 1, and a multi-stage overflow structure 4 with different heights is also provided on the open side wall of the water filter chamber 3.
[0032] Based on the above structure, since the side wall of the water filter chamber 3 is opened and part of the structure of the filter part is arranged on the side wall of the opening, water can flow into the water filter chamber 3 from the side wall of the opening and then flow out from the water outlet 2. Impurities in the water are removed by the filter part, and since the multi-stage overflow structure 4 is a structure of different heights, different filtering effects can be achieved for water bodies with different water levels. When heavy rain occurs, the multi-stage overflow structure 4 will hinder the flow of water, causing the water body to gradually rise and enter the water filter chamber 3 directly through the filter structure from the top of the water filter chamber 3, and then be discharged directly from the water outlet 2. At this time, the obstruction of the overflow well can achieve partial water storage function, avoiding the sudden influx of water into the municipal pipeline network and affecting it. At the same time, the multi-stage overflow structure 4 in this scheme can achieve different overflow effects according to the height of the water body, realize the flow of water, avoid the breeding of bacteria in the water body, and affect reuse.
[0033] As an example, the support body 1 is a cubic structure as a whole, the filter cavity is arranged at the center of the support body 1, and a receiving groove 31 is arranged on the top of the filter cavity.
[0034] Based on the above structure, the filter part can be fixed by the accommodating groove 31. On the one hand, the installation position can be located, and on the other hand, the filter part can be limited to prevent the filter part from being washed away by water. At the same time, due to the existence of the accommodating cavity, the filter structure set thereon does not need to be fixed, which simplifies the installation process.
[0035] As an example, the filter part may include a first filter screen 5 and a second filter screen 6; the first filter screen 5 is arranged at the opening of the side wall of the support body 1, and the second filter screen 6 is placed in the accommodating groove 31; the first filter screen 5 and the second filter screen 6 are both rectangular structures, and the first filter screen 5 is assembled on the support body 1 on both sides by multiple bolts 7.
[0036] Based on the above structure, the first filter screen 5 is detachably set on the side wall of the support body 1 by bolts 7, and the second filter screen 6 is placed in the accommodating groove 31. The first filter screen 5 and the second filter screen 6 can be easily disassembled and assembled to clean impurities on the first filter screen 5 and the second filter screen 6, which is convenient for later maintenance.
[0037] As an example, the first filter screen 5 may include a filter screen plate 51 and a water-permeable plate 52; the water-permeable plate 52 is provided at the lower side of the filter screen plate 51, and a large water-permeable hole 53 is provided at the center of the water-permeable plate 52;
[0038] Based on the above structure, when the water storage capacity of the water body is small, the water body directly enters the interior of the support body 1 from the large permeable hole 53. As the water level of the water body rises, it gradually rises to the filter plate 51, and the water body is processed by the filter plate 51. During long-term operation, even if the filter plate 51 is blocked, the water body can still enter the support body 1 through the permeable holes at the bottom, thereby realizing the free flow of the water body.
[0039] As an example, the multi-stage overflow structure 4 may include a water baffle 41 and an overflow hole 42. The overflow hole 42 is located at the center of the width direction of the water baffle 41, and the overflow holes 42 are evenly spaced along the length direction of the water baffle 41. The water baffle 41 is connected to the opening of the water filter chamber 3 by a bolt 7.
[0040] The first-stage overflow hole 42 is a predetermined distance away from the bottom of the water baffle 41 , and the last-stage overflow hole 42 is a predetermined distance away from the top of the water baffle 41 .
[0041] Based on the above structure, the relatively clean water coming in from the first filter part is slowly transported to the filter chamber through the overflow hole 42. The purpose is to make the water flow and delay the water from entering the municipal pipe network during heavy rain to find out its impact. In normal times, it can drive the water to flow eastward, forming flowing living water and reducing the growth of bacteria. When the water level rises, multiple overflow holes 42 will participate in the overflow, accelerating the flow to a certain extent.
[0042] As an example, a lifting layer 32 can be set at the bottom of the water filter chamber 3, and the multi-stage overflow structure 4 is set on the lifting layer 32. The highest position of the lifting layer 32 is level with the highest position of the large water-permeable hole 53; the water outlet part 2 is a water outlet pipe with a diameter of 300 mm.
[0043] The size of the large permeable hole 53 is 100*90mm, the diameter of the overflow hole 42 is 20mm, the distance between adjacent overflow holes 42 is 58mm, the distance between the first-level overflow hole 42 and the bottom of the water retaining plate 41 and the distance between the last-level overflow hole 42 and the top of the water retaining plate 41 are both 50mm, and the height of the lifting layer 32 is 140mm.
[0044] Through this solution, rainwater can be retained, flow can be regulated, discharge time can be extended, and runoff pollution can be reduced.
[0045] Example 2
[0046] like Figures 5 and 6 As shown, the utility model provides a technical solution:
[0047] An ecological wet pond water regulation system, which at least includes but is not limited to a front pond 8, a water storage pond 9 and a multi-stage overflow well 10; a gabion layer 11 of a predetermined height is provided in the water retaining pile between the front pond 8 and the water storage pond 9, and the water storage pond 9 is connected to the multi-stage overflow well 10.
[0048] Based on the above structure, the front pond 8 is usually a naturally formed pond. A gabion layer 11 is set between the front pond 8 and the reservoir 9. The water body can be preliminarily filtered through the gabion layer 11, and most of the impurities are blocked in the front pond 8, so that the water body flowing into the reservoir 9 has a certain degree of cleanliness. Then, by connecting with the multi-stage overflow well 10, the water body in the reservoir 9 can flow slowly into the municipal pipeline network for reuse.
[0049] As an example, the horizontal plane at the highest position of the multi-stage overflow well 10 is not lower than the horizontal plane at the highest position of the gabion layer 11. In this way, the multi-stage overflow well 10 can have a certain water retaining function and increase its deceleration function for the water body.
[0050] As an example, a concrete cushion layer 81 and a soil layer 82 can be set at the bottom of the front pond 8. The concrete cushion layer 81 is set on the soil layer 82. The concrete cushion layer 81 forms an arc structure at the bottom of the front pond 8. The highest point of the concrete cushion layer 81 is level with the lowest point of the gabion layer 11.
[0051] Based on the above structure, the concrete cushion layer 81 is provided to enable the front pond 8 to settle the soil, thereby preventing excessive particulate impurities from entering the water storage pond 9.
[0052] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
