[0034] The technical solution of the utility model is described in detail below in conjunction with the accompanying drawings and specific embodiments to further understand the purpose, solution and effect of the utility model, but it is not intended to limit the scope of protection of the claims attached to the utility model.

It should be understood by those skilled in the art that technical users or manufacturers may refer to the same component or part by different nouns or terms. This specification and subsequent claims do not use differences in names as a way to distinguish components or parts, but use differences in functions of components or parts as the criteria for distinction. "Including" and "comprising" mentioned throughout the specification and subsequent claims are open-ended terms and should be interpreted as "including but not limited to". In addition, the word "connected" here includes any direct and indirect means of connection.

[0037] like Figure 1 and Figure 2 As shown, the rainwater interception well of the utility model comprises a well body 100 extending vertically, and the top surface of the well body 100 is, for example, flush with the surface of the area where it is located, or the top surface of the well body 100 is slightly lower than the surface of the area where it is located.

[0038] The well body 100 includes a rainwater inlet area 110 and a rainwater outlet area 120, which are arranged on the left and right. The bottoms of the rainwater inlet area 110 and the rainwater outlet area 120 are connected, and the rainwater inlet 130 is arranged at the top of the rainwater inlet area 110. The rainwater outlet area 120 includes a rainwater outlet 121.

[0039] The well main body 100 includes an initial rainwater storage part 140 located at the bottom of the rainwater discharge area 120 .

[0040] Rainwater enters the rainwater inlet 130 into the rainwater inlet area 110, and enters the rainwater discharge area 120 after a first sedimentation in the rainwater inlet area 110. The rainwater entering the rainwater discharge area 120 first passes through the rainwater storage part 140 for a second sedimentation, and then is discharged through the rainwater discharge outlet 121. The rainwater discharged through the rainwater discharge outlet 121 is relatively clean, which reduces the subsequent processing steps and can also avoid pipeline blockage.

[0041] The bottom of the rainwater inlet area 110 and the bottom of the rainwater discharge area 120 have a connection height H1, and the initial rainwater storage part 140 has a height H2. The connection height H1 is not higher than the height H2 of the initial rainwater storage part 140, that is, the connection height H1 is at least the same as the height H2 of the initial rainwater storage part 140, or the connection height H1 is lower than the height H2 of the initial rainwater storage part 140. The initial rainwater carrying a large amount of silt and impurities enters the rainwater inlet 130 into the rainwater inlet area 110. Since the connection height H1 is not higher than the height H2 of the initial rainwater storage part 140, the initial rainwater cannot directly enter the initial rainwater storage part 140 of the rainwater discharge area 120, nor can it be discharged through the rainwater discharge outlet 121. The rainwater carrying a large amount of silt and impurities enters the rainwater inlet 130 into the rainwater inlet area 110, and enters the initial rainwater storage part 140 of the rainwater discharge area 120 after sedimentation to remove the silt and bulk materials. The rainwater undergoes secondary sedimentation in the initial rainwater storage unit 140 , and relatively clean rainwater is discharged through the rainwater discharge port 121 .

[0042] like Figure 1 As shown, the initial rainwater storage part 140 includes a storage wall 141 and a storage cover 142 covering the storage wall 141. The storage wall 141 is, for example, a rectangular body, a rectangular body or an irregular body with a height H2, and can be adaptively designed according to the bottom shape of the rainwater discharge area 120, which is not limited by the present invention.

[0043] The storage cover 142 is floatingly connected to the storage wall 141. When the initial rainwater stored in the storage wall 141 is small, the storage cover 142 automatically opens to facilitate the entry of the initial rainwater. When the storage wall 141 is full, the storage cover 142 automatically closes, which not only prevents the rainwater containing a large amount of impurities in the storage wall 141 from overflowing, but also facilitates the discharge of rainwater through the rainwater outlet 121.

[0044] The storage cover 142 has a communication hole 142a for replenishing the discharge volume of the initial rainwater drainage pipe 143, so that the floating storage cover 142 can close the initial rainwater storage part 140 under the action of the buoyancy of water.

[0045] In this embodiment, the storage cover 142 includes a connection end 142b and a free end 142c, wherein the connection end 142b is located at the position where the storage cover 142 is connected to the storage wall 141, and the free end 142c is located at the end opposite to the connection end 142b, and the storage cover 142 is connected to the storage wall 141 by rotation, for example, by hinged connection. The connection end 142b is closer to the rainwater inlet area 110 than the free end 142c. The initial rainwater enters the upper part of the initial rainwater storage part 140 after being precipitated in the rainwater inlet area 110, and the flowing rainwater directly enters the storage wall 141.

[0046] In the present invention, the height of the rainwater outlet 121 is higher than the height of the initial rainwater storage part 140. Preferably, the bottom of the rainwater outlet 121 is flush with the top of the initial rainwater storage part 140. Rainwater after secondary sedimentation in the initial rainwater storage part 140 can be discharged through the rainwater outlet 121.

[0047] In another embodiment of the present invention, Figure 2 As shown, the storage cover 142 is connected to the storage wall 141 by a plurality of vertical limit floats, and rainwater enters through the gap between the storage cover 142 and the storage wall 141. As the water level rises, the storage cover 142 is lifted up to close the storage wall 141.

[0048] like Figure 1 and Figure 2 As shown, a maintenance entrance 122 is provided at the top of the rainwater discharge area 120 , and a ladder or the like may also be provided in the rainwater discharge area 120 for workers to enter the well for maintenance, repair, disinfection, silt removal, and the like.

[0049] Preferably, in one embodiment of the rainwater interception well, a filter is provided at the rainwater inlet 130 at the top of the rainwater inlet area 110 to perform a first filtering of the rainwater, for example, to remove larger debris such as leaves.

[0050] The volume V of the initial rainwater interception well of the utility model is determined according to its service area as follows: V = AF, where A (unit is m 2 ) is the service area, and F (in mm) is the rainfall thickness.

[0051] Generally, the initial rainwater thickness F on relatively clean ground is 4-6mm, and the initial rainwater thickness F on municipal roads is 6-12mm. According to different locations of different projects in different cities, the initial rainwater thickness F and the service area A of the rainwater outlet are selected to calculate the volume V of the initial rainwater.

[0052] Among them, the initial rainwater enters room A through the rainwater inlet 130, and enters room B after sedimentation and removal of sand and large particles. The initial rainwater enters room C of the initial rainwater storage part 140. The maximum volume of room C is V1, that is, the volume of the initial rainwater storage part 140 is V1.

[0053] The drainage volume of the initial rainwater drainage pipe 143 of the initial rainwater storage part 140 during rainfall is V2, and the volume V1 of the initial rainwater storage part 140 is calculated as follows: V1=V-V2.

[0054] When the rainwater gradually fills up the C chamber, the floating plate floats under the buoyancy of the water until it is automatically closed. At this time, the rainwater that enters again is relatively clean rainwater and is discharged through the rainwater outlet 121.

[0055] The communication hole 142a of the storage cover 142 is, for example, disposed at the center of the storage cover 142, and its diameter is the same as the diameter of the initial rainwater drainage pipe 143. The diameter of the communication hole 142a is calculated according to the initial rainwater drainage time, for example, 2 hours after rain.

[0056] Of course, the present invention may have many other embodiments. Without departing from the spirit and essence of the present invention, technicians familiar with the field can make various corresponding changes and deformations based on the present invention, but these corresponding changes and deformations should all fall within the scope of protection of the claims attached to the present invention.
