[0039] In order to make the technical problems, technical solutions and beneficial effects to be solved by this application more clearly understood, this application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0040] It should be noted that when an element is referred to as being “fixed on” or “disposed on” another element, it may be directly on the other element or indirectly on the other element. When an element is referred to as being “connected to” another element, it may be directly connected to the other element or indirectly connected to the other element.

[0041] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application.

[0042] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. Throughout the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0043] Please also refer to Figures 1 to 7 , the rainwater storage structure in the integrated pipe corridor provided by this application is now described. It should be noted that rainwater flows into the pipe corridor from the ground; in this embodiment, for the convenience of description, the flow direction of rainwater is defined as from back to front. The rainwater storage structure in the integrated pipe corridor proposed in this application includes a foundation pit 10, a box body 1, a partition 2 and a baffle 3.

[0044] The foundation pit 10 is opened on the ground of the pipe gallery, and adopts a structure with a rectangular cross-section, a hollow interior, and an upward opening. The length direction of the foundation pit 10 is parallel to the front-to-back direction to allow rainwater to flow in.

[0045] The box body 1 is fixedly arranged in the foundation pit 10, and adopts a structure with a hollow interior and an upward opening to receive and accommodate rainwater flowing into the foundation pit 10; it should be noted that backfill soil is filled between the outer wall of the box body 1 and the inner wall of the foundation pit 10 to prevent rainwater from flowing out of the outside of the box body 1 and the soil between the box body 1 and the foundation pit 10 from getting wet, which may affect the stability of the box body 1 in a fixed state.

[0046] The partition 2 is fixedly arranged in the box body 1; the front end and left and right sides of this partition 2 are connected to the inner wall of the box body 1, and the partition 2 is inclined from the front to the back and downward, so that the fluid falling on the partition 2 flows toward the rear side; and, there is a gap space between the rear end of the partition 2 and the inner wall of the box body 1 for the fluid to pass through, so that the flowing liquid flows into the lower side of the partition 2 through the gap space.

[0047] Baffle 3 is slidably connected to the underside of partition 2 in the forward-backward direction and is drivingly connected to a linear drive member 4. During use, linear drive member 4 drives baffle 3 to close or avoid the gap. This linear drive member 4 is fixed to the underside of partition 2. Because partition 2 is arranged at an angle, and the liquid below it typically does not exceed the horizontal plane at the center of partition 2, fixing all or part of linear drive member 4 to the underside of partition 2 can effectively protect linear drive member 4 (preventing it from being soaked by liquid).

[0048] In an embodiment of the present application, the internal space of the box body 1 can be divided into two parts, an upper part and an lower part, by the combined structure of the partition 2 and the baffle 3; based on this, in the early stage of rain, the baffle 3 can be driven by the linear drive component 4 to move to a position to avoid the gap space between the partition 2 and the box body 1, so that the fluid can enter the partial space on the lower side of the partition 2; then, in the middle and late stages of rain, the baffle 3 can be driven by the linear drive component 4 to move to a position to close the gap space between the partition 2 and the box body 1, so that the rainwater that subsequently flows in is stored in the partial space on the upper side of the partition 2.

[0049] Compared with the prior art, the rainwater storage structure in the integrated pipeline corridor provided by this embodiment can classify and store polluted rainwater and pure rainwater to facilitate their separate treatment and use in the later stage.

[0050] In some embodiments, as Figure 4 and Figure 6 As shown, a guide hole 31 extending in the front-to-back direction is provided on the baffle 3, and a protrusion 21 with a T-shaped vertical cross-section and sliding connection in the guide hole 31 is fixedly connected to the lower side of the partition 2; after the partition 2 and the baffle 3 are combined, the protrusion 21 passes through the guide hole 31 and hangs the baffle 3, realizing the sliding connection relationship between the baffle 3 and the partition 2, ensuring that the baffle 3 and the partition 2 are always in a connected state.

[0051] In some embodiments, as Figure 4 and Figure 6 As shown, the linear drive member 4 includes two swing arms 41 and a double-headed screw 42 .

[0052] Two swing arms 41 are arranged side by side on the lower side of the partition 2 in the left-right direction, and each swing arm 41 is hinged to the baffle 3 in the up-down direction; wherein, the swing end of each swing arm 41 is hinged to a sliding seat 5 in the up-down direction, and the sliding seat 5 is slidably connected to the lower side of the partition 2 in the left-right direction.

[0054] The double-headed screw 42 has two threaded portions with opposite thread directions, and the two threaded portions are respectively threadedly connected to the two sliding seats 5 .

[0055] By adopting the above technical solution, when the rotating motor 421 drives the double-headed screw 42 to rotate, the two sliding seats 5 move toward or away from each other, so that the partition plate 2 moves toward or away from the gap space.

[0056] In some embodiments, as Figure 7 As shown, the sliding seat 5 is provided with a through hole 51 which runs through in the left-right direction and is suitable for the double-headed screw 42 to pass through; the sliding seat 5 is provided with a mounting groove 52 on one side facing the left-right direction and connected to the through hole 51, and a transmission nut 53 threadedly connected to the double-headed screw 42 is fixedly connected in the mounting groove 52 to realize the combination of the sliding seat 5 and the transmission nut 53, and the sunken installation of the transmission nut 53 on the sliding seat 5.

[0057] In some embodiments, as Figure 5 and Figure 6 As shown, the rotating motor 421 is fixedly arranged on the outer side of the box body 1, and the outer side of the box body 1 can also be detachably connected with a protective shell 11 suitable for being placed on the outer periphery of the rotating motor 421; in actual use, the protective shell 11 needs to be buried on the inner wall of the foundation pit 10 on the side of the box body 1.

[0058] In some embodiments, as Figure 1 、 Figure 4 and Figure 5 As shown, the upper side of the partition 2 has a plurality of guide strips 22 arranged at intervals along the left-right direction, and each guide strip 22 extends along the front-back direction to increase the flow rate of the fluid on the partition 2 and avoid the residue of polluted rainwater on the partition 2.

[0059] In some embodiments, as Figure 4 and Figure 5 As shown, the inner side surface of the box body 1 is provided with a groove 12 connected to the aforementioned gap space; when the baffle 3 moves to the closed gap space, the baffle 3 is inserted into the groove 12, and the inner bottom surface of the groove 12 supports the baffle 3, thereby improving the stability of the baffle 3 in the closed gap space.

[0060] It should be noted that in actual design, a rubber cushion is usually fixed on the inner wall of the groove 12; when the baffle 3 is inserted into the groove 12, the cushion deforms to seal the gap between the baffle 3 and the inner wall of the groove 12, preventing liquid from flowing from the space above and below the partition 2.

[0061] In some embodiments, as Figures 3 to 5As shown, the box body 1 is provided with a mounting hole 13 communicating with the interior thereof, and the mounting hole 13 is located on the lower side of the partition 2, specifically on the side opposite to the aforementioned gap space.

[0065] In actual use, the filter cover 7 can close the entrance of the foundation pit 10 and restrict the passage of impurities in rainwater.

[0066] In some embodiments, as Figures 1 to 4 As shown, the filter cover 7 has a plurality of rods 71 extending downward and arranged in parallel in the horizontal direction. The rainwater storage structure in the integrated pipe gallery also includes a sinking trough 20 and a plurality of slots 201.

[0067] The sinking trough 20 is used to be opened on the ground of the pipe gallery, and the sinking trough 20 is coaxially connected to the foundation pit 10, that is, it is set along the edge of the opening of the foundation pit 10 and is flanged outward.

[0068] The plurality of slots 201 are all provided at the bottom of the sinking tank 20 and are suitable for correspondingly inserting the plurality of insertion rods 71 mentioned above to fix the position of the filter cover 7 and limit the movement of the filter cover 7 in the horizontal direction.
