Description

Technical Field

[0001] The utility model relates to the technical field of overflow wells, in particular to a multi-layer overflow port slow-release wellbore. Background Art

[0002] Sponge city is a new generation of urban stormwater management concept. It aims to make the city have good "elasticity" in adapting to environmental changes and coping with natural disasters caused by rain by imitating the characteristics of sponges. This concept emphasizes that the city can absorb, store, infiltrate and purify water like a sponge during rainfall, and release and utilize these stored water resources when needed to achieve natural accumulation, natural infiltration and natural purification of rainwater. The overflow device is an important part of the sponge city drainage system. The overflow device is usually installed in sponge facilities such as rain gardens, sunken green spaces and grass-planted ditches to discharge rainwater exceeding the standard into the rainwater pipe network in the form of overflow.

[0003] For example, Chinese patent CN219080523U discloses a composite slow-release micro-overflow rainwater outlet shaft, including a first shaft connecting buckle A end, a slow-release shaft, a concealed shaft A and a concealed shaft B. The first shaft connecting buckle A end is connected to a slow-release shaft below, and shaft slow-release holes are arranged around the outer wall of the slow-release shaft. A second shaft connecting buckle B end is arranged below the concealed shaft A, and the concealed shaft A is connected to a concealed shaft B below.

[0004] However, the overall structure of the existing micro-overflow device is too simple. Usually, the top of the micro-overflow device is set parallel to the ground or higher than the ground. When the amount of rain is too large, impurities such as leaves on the ground will enter the overflow well with the water flow. If this continues for a long time, it will cause blockage in the overflow well and affect the drainage effect of the micro-overflow device. To solve the above problems, a multi-layer overflow port slow-release well is proposed. Utility Model Content

However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0023] Embodiment 1

[0024] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, the utility model provides a multi-layer overflow slow-release wellbore, including a well cover device 1 and a wellbore device 2, the bottom end of the well cover device 1 is clamped with the top end of the wellbore device 2, the well cover device 1 includes a mounting ring 11, a convex cover plate 12, a concave cover plate 13 and a mounting rod 17, the top end of the convex cover plate 12 is fixedly installed with the top end of the concave cover plate 13, and the bottom end of the convex cover plate 12 is welded to the inner side of the mounting ring 11, the top end of the mounting rod 17 is welded to the bottom of the concave cover plate 13, the inner edge of the mounting ring 11 is clamped with a filter screen 111, and the top end of the mounting rod 17 is clamped with a filter screen 111. A plurality of rotating plates 18 are rotatably installed in the annular array, and a blocking net 19 is arranged between two adjacent rotating plates 18. A plurality of springs 110 are movably installed in the annular array at the bottom end of the mounting rod 17, and one end of the spring 110 is fixedly connected to one side of the rotating plate 18. A plurality of water inlet holes 14 are penetrated through the top annular array of the convex cover plate 12, and a plurality of water inlet holes 2 16 are penetrated through the top annular array of the concave cover plate 13. A plurality of blocks 15 are welded to the bottom annular array of the mounting ring 11, and a plurality of notches 112 are provided on the inner wall annular array of the mounting ring 11.

[0025] The following is a detailed description of the specific settings and functions of this embodiment: When there is heavy rain, rainwater will gather on the top of the concave cover plate 13 to form a large water flow. The large water flow quickly impacts downward onto the rotating plate 18 and the blocking net 19 through the water inlet hole 16. The rotating plate 18 rotates downward under the impact of the water flow. Because the bottom end of the rotating plate 18 is connected to a spring 110, the rotating plate 18 will swing up and down under the action of the water flow. The combination of the blocking net 19 and the filter net 111 can block relatively large impurities in the rainwater. At the same time, with the flushing of rainwater and the swinging of the rotating plate 18, the impurities on the blocking net 19 will fall on the top of the filter net 111. The blocking net 19 and the filter net 111 can prevent larger impurities in the rainwater from flowing into the wellbore device 2 without affecting the drainage capacity.

[0026] Embodiment 2

[0027] like Figure 1 - Figure 3 As shown, the shaft device 2 includes a shaft main pipe 21, a second mounting ring 23, a support frame 25 and a vertical rod 28. The two sides of the shaft main pipe 21 are fixedly installed with the inner wall of the shaft main pipe 21, the two ends of the vertical rod 28 are welded to the two ends of the shaft main pipe 21, and the outer wall of the vertical rod 28 is evenly fixedly installed with a plurality of filter plates 26, the bottom of the second mounting ring 23 is welded to the top of the shaft main pipe 21, and the top annular array of the second mounting ring 23 is provided with a plurality of card grooves 27, the bottom end of the card block 15 is carded with the inner wall of the card groove 27, the bottom of the mounting rod 17 is plugged with the top of the support frame 25, and the outer wall of the shaft main pipe 21 is symmetrically fixedly connected with two branch pipes 22, and the inner walls of the two branch pipes 22 are provided with a permeable geotextile 24.

[0028] The effects achieved by the entire embodiment are as follows: the manhole cover device 1 and the shaft device 2 can be quickly installed by means of the engagement of the clamping block 15 with the clamping slot 27; when a large amount of impurities such as leaves are accumulated on the filter net 111, it is convenient for the management personnel to disassemble the manhole cover device 1; a plurality of filter plates 26 are added to the shaft main pipe 21; the plurality of filter plates 26 form a vertical multi-layer filtering structure; when rainwater flows into the shaft main pipe 21, the plurality of filter plates 26 can filter the rainwater layer by layer, thereby greatly reducing the situation where impurities in the rainwater cause the overflow well to be blocked.

[0029] The use method and working principle of the device: The multi-layer overflow slow-release wellbore is composed of a well cover device 1 and a wellbore device 2. When the device is installed, the wellbore device 2 is installed underground, and the top of the wellbore device 2 is flush with the ground. Then, after aligning the multiple clamping blocks 15 of the well cover device 1 with the clamping slots 27, the well cover device 1 and the wellbore device 2 are quickly installed by clamping the clamping blocks 15 with the clamping slots 27, which facilitates the quick installation and removal of the well cover device 1.

[0030] When the device is in use, rainwater flows into the well pipe 21 through the water inlet hole 14 and the water inlet hole 2 16. In the case of heavy rain, the rainwater will gather at the top of the concave cover plate 13 to form a large water flow. The large water flow quickly impacts downward on the rotating plate 18 and the blocking net 19 through the water inlet hole 2 16. The rotating plate 18 rotates downward under the impact of the water flow. Since the bottom end of the rotating plate 18 is connected to a spring 110, the rotating plate 18 swings up and down under the action of the water flow. The blocking net 19 and the filter net 111 can be combined to filter relatively large impurities in the rain. The impurities on the blocking net 19 will fall on the top of the filter net 111 as the rainwater washes and the rotating plate 18 swings. The blocking net 19 and the filter net 111 can prevent larger impurities in the rainwater from flowing into the wellbore device 2 without affecting the drainage capacity. When the drainage capacity of the well cover device 1 is obviously weak, the management personnel can open the well cover device 1 and remove the filter net 111 to facilitate the cleaning of the blocking net 19 and the filter net 111, which is convenient for use, reduces the probability of blockage in the overflow well, and ensures the normal drainage effect of the micro overflow device.

[0031] At the same time, multiple filter plates 26 are added in the well main pipe 21, and the multiple filter plates 26 form a vertical multi-layer filter structure. When rainwater flows into the well main pipe 21, the multiple filter plates 26 can filter the rainwater layer by layer, which greatly reduces the situation where impurities in the rainwater cause the overflow well to be blocked.

[0032] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
