Description

Technical Field

[0001] The utility model relates to the technical field of rainwater overflow wells, and in particular to an environmentally friendly overflow outlet for collecting rainwater in a sponge city. Background Art

[0002] The environmentally friendly overflow outlet for rainwater collection in sponge cities refers to the overflow well. The overflow well is a type of drainage inspection well, generally found in interception-type combined sewer systems and urban drainage engineering pump station systems. It has the function of controlling the flow rate of water. The existing overflow well is mainly composed of a well pipe, a sewage interception fence and a four-sided pyramid-shaped filter shell cover. The overflow well will be buried underground.

[0003] Chinese patent publication number CN218233705U, publication time 20230106, discloses an environmentally friendly overflow outlet for rainwater collection in sponge cities, including an overflow pipe, a water pipe connected to the side wall of the overflow pipe and a sewage interception fence attached to the upper end of the overflow pipe, a square frame is fixedly sleeved on the outer wall of the overflow pipe, a quadrangular pyramid filter cover is slidably inserted inside the square frame, and two symmetrical square grooves are provided at the front and rear ends of the square frame, a square block is slidably fitted inside the square groove, a connecting rod is fixedly connected to the lower end of the block, the connecting rod is slidably inserted in the inner bottom end of the square groove, and a spring is slidably sleeved on the outer wall of the connecting rod.

[0004] For example, the above-mentioned existing environmentally friendly overflow outlet for rainwater collection in sponge cities can move downward when the quadrangular pyramid filter shell cover is under pressure to avoid damage, which is beneficial to the normal use of the quadrangular pyramid filter shell cover, and can automatically move upward to resume use after the pressure on the quadrangular pyramid filter shell cover is no longer there. At the same time, the quadrangular pyramid filter shell cover is easy to disassemble and assemble. In the specific implementation process, the threaded barrel is directly screwed into the positioning of the threaded column to achieve the limiting of the square block and the rectangular block. Since the spring is not equipped with the shock absorbing assembly, the rectangular block is in a state of continuous collision with the threaded barrel, which causes the screwed threaded barrel to loosen. Therefore, it is urgent to propose a corresponding environmentally friendly overflow outlet for rainwater collection in sponge cities to solve the above problems. Utility Model Content

At this time, the sewage intercepting basket 6 can be pulled upward by the locking rod 9 and the overflow pipe 2 is separated, thereby ensuring the convenience of using the environmentally friendly overflow port for rainwater collection in sponge cities.

[0027] Specifically, Figure 2 and Figure 3As shown, the elastic component includes a spring 14 and a micro shock absorber 15, which are fixedly installed between the connecting plate 13 and the inner surface wall at the bottom of the convex seat 5. When the force on the filter cover 4 exceeds the internal force of the spring 14, the filter cover 4 drives the outer plate 12 and the connecting plate 13 to press the spring 14, and the micro shock absorber 15 is synchronously extended and retracted. Similarly, after the filter cover 4 loses its restraining force, the spring 14 will push the connecting plate 13 and the outer plate 12 to reset, and the micro shock absorber 15 can effectively realize the shock absorption of the connecting plate 13 and the outer plate 12. The top of the outer plate 12 has a rubber interference fit. Pad 16, the bottom of the rubber pad 16 abuts against the top of the fastening rod 17, the interference fit rubber block 16 ensures its own stable position, the bottom of the rubber block 16 abuts against the fastening rod 17, so that the loosening of the fastening rod 17 can be limited by friction, and a horizontal bar 10 is overlapped on the top of the outer panel 12, and the horizontal bar 10 is engaged with the top of the boss 5 through the L-shaped groove 11, and the horizontal bar 10 is magnetically matched with the inner surface wall of the top of the boss 5.

Finally, the rubber block 16 is inserted into the top of the outer plate 12. When the force on the filter cover 4 exceeds the internal force of the spring 14, the filter cover 4 drives the outer plate 12 and the connecting plate 13 to press the spring 14 down, and the micro shock absorber 15 is retracted and extended synchronously. Similarly, after the filter cover 4 loses its restraining force, the spring 14 will push the connecting plate 13 and the outer plate 12 to reset, and the micro shock absorber 15 can effectively realize the shock absorption of the connecting plate 13 and the outer plate 12, and at the same time, the rubber block 16 with interference fit 6 ensures its own stable position, and the bottom of the rubber block 16 abuts against the fastening rod 17, so that the loosening of the fastening rod 17 can be limited by friction, thereby further ensuring the stability of the installation of the filter cover 4, thereby improving the stability of the use of the environmentally friendly overflow port for rainwater collection in sponge cities, and the upper frame 7 and the fixing block 8 are screwed together by the locking rod 9 to achieve the fixation of the sewage interception basket 6.
