Description

Technical Field

[0001] This utility model relates to the field of rainwater storage tank technology, and in particular to a high-efficiency and environmentally friendly sponge city rainwater storage tank. Background Technology

[0002] Sponge city is a new generation of urban stormwater management concept, referring to a city's ability to adapt to environmental changes and cope with natural disasters caused by rainwater, much like a sponge. To address and mitigate stormwater peaks, achieve rainwater recycling, and prevent initial rainwater pollution of receiving water bodies, artificial rainwater storage tanks are constructed in sponge city development. These tanks are typically built beneath public areas such as roads, plazas, parking lots, green spaces, parks, and urban waterways to temporarily store rainwater and play a positive role in its management. Rainwater storage tanks are rainwater collection facilities that primarily retain peak runoff during the period of highest flow, allowing rainwater to gradually drain after the maximum flow decreases. This achieves the goals of mitigating stormwater peaks, improving rainwater utilization, controlling initial rainwater pollution of receiving water bodies, and positively impacting drainage management between different drainage areas.

[0003] Existing rainwater storage tanks accumulate silt at the bottom, requiring pumps to remove it. However, the pumping range of these pumps cannot be accurately controlled, causing them to pump out rainwater along with the silt. This results in low accuracy and efficiency in silt removal, wasting rainwater and reducing the operational efficiency of the rainwater storage tanks.

[0004] Therefore, there is an urgent need to provide a high-efficiency and environmentally friendly sponge city rainwater storage tank to solve the above problems. Utility Model Content

[0012] Through the above technical solution, the opening and closing motor drives the worm shaft to rotate, and the worm shaft drives the worm wheel to rotate.

[0013] The present invention is further configured such that: the sludge removal mechanism includes a sludge removal motor fixed to the top wall of the mounting housing, and the output shaft of the sludge removal motor is fixedly connected to a pulley shaft via a coupling.

[0014] Through the above technical solution, the sludge discharge motor drives the pulley shaft to rotate.

[0015] The present invention is further configured such that: a sludge discharge shaft with one end penetrating through and extending into the housing is rotatably installed inside the U-shaped sedimentation tube; a synchronous belt is friably connected between the outer surface of the sludge discharge shaft and the outer surface of the pulley shaft; and a spiral blade is fixedly installed on the outer surface of the sludge discharge shaft.

[0016] Through the above technical solution, the pulley shaft drives the sludge discharge shaft and the spiral blades to rotate via a synchronous belt.

[0018] With the above technical solution, sludge is discharged into the sludge storage tank through the sludge discharge pipe, and the opening and closing of the sludge discharge pipe is controlled by an electric valve.

[0020] 1. This utility model, by providing a rotating mechanism and a sludge discharge mechanism, can discharge the sludge inside the U-shaped sedimentation tube. The C-shaped rotating tube can accurately control the suction range, which improves the accuracy and efficiency of the equipment in suctioning sludge, and can also effectively avoid the waste of clean rainwater, thereby improving the overall operating efficiency of the rainwater storage tank.

[0028] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0029] Please see Figures 1-5A high-efficiency and environmentally friendly sponge city rainwater storage tank includes a rainwater storage tank body 1. A U-shaped sedimentation pipe 2 is fixedly installed at the bottom of the rainwater storage tank body 1. An installation shell 3 is fixedly installed on one side of the U-shaped sedimentation pipe 2. A rotating mechanism 4 is provided inside the U-shaped sedimentation pipe 2 to confirm the sludge suction range. The rotating mechanism 4 includes a C-shaped rotating pipe 401 rotatably installed inside the U-shaped sedimentation pipe 2. Both ends of the C-shaped rotating pipe 401 are sealed to both sides of the U-shaped sedimentation pipe 2 through sealing rings. A rotating shell 402 is fixedly installed on the outer surface of the U-shaped sedimentation pipe 2. A connecting frame pipe 403 is fixedly installed on one side of the C-shaped rotating pipe 401, with one end penetrating and extending into the installation shell 3. A worm gear 404 is fixedly installed on the outer surface of the connecting frame pipe 403. An opening and closing motor 405 is fixedly installed on one side of the mounting shell 3. The output shaft of the opening and closing motor 405 is fixedly connected to a worm shaft 406 through a coupling. The outer surface of the worm shaft 406 meshes with the outer surface of the worm wheel 404. The filtered rainwater flows into the rainwater storage tank body 1. Through the inclined structure at the bottom of the rainwater storage tank body 1, the sludge settles into the U-shaped sedimentation pipe 2. The opening and closing motor 405 drives the worm shaft 406 to rotate, and the worm shaft 406 drives the worm wheel 404 to rotate. The worm wheel 404 drives the C-shaped rotating pipe 401 to rotate through the connecting frame pipe 403. The C-shaped rotating pipe 401 rotates through the U-shaped sedimentation pipe 2 and the rotating shell 402, so that the C-shaped rotating pipe 401 seals the top of the U-shaped sedimentation pipe 2.

[0030] like Figure 3 and Figure 4 As shown, the interior of the mounting shell 3 is equipped with a sludge removal mechanism 5 for suctioning sludge. The sludge removal mechanism 5 includes a sludge removal motor 501 fixed to the top wall of the mounting shell 3. The output shaft of the sludge removal motor 501 is fixedly connected to a pulley shaft 502 via a coupling. A sludge removal shaft 503 with one end penetrating and extending into the interior of the mounting shell 3 is rotatably installed inside the U-shaped sedimentation tube 2. A synchronous belt 504 is frictionally connected between the outer surface of the sludge removal shaft 503 and the outer surface of the pulley shaft 502. A spiral blade 505 is fixedly installed on the outer surface of the sludge removal shaft 503. The sludge removal motor 501 drives the pulley shaft 502 to rotate. The pulley shaft 502 drives the sludge removal shaft 503 and the spiral blade 505 to rotate via the synchronous belt 504, so that the spiral blade 505 pushes and discharges the sludge inside the U-shaped sedimentation tube 2. The sludge removal shaft 503 and the U-shaped sedimentation tube 2 are sealed together by a sealing ring to prevent water leakage at the connection between the U-shaped sedimentation tube 2 and the sludge removal shaft 503.

[0031] like Figure 2As shown, a sludge storage mechanism 6 for storing pumped sludge is provided on the other side of the U-shaped sedimentation pipe 2. The sludge storage mechanism 6 includes a sludge discharge pipe 601 fixed to the other side of the U-shaped sedimentation pipe 2. An electric valve 602 is fixedly installed at the bottom end of the sludge discharge pipe 601. A sludge storage tank 603 is fixedly installed at the bottom end of the electric valve 602. Sludge is discharged into the sludge storage tank 603 through the sludge discharge pipe 601. The electric valve 602 controls the opening and closing of the sludge discharge pipe 601 to prevent rainwater from being discharged from the sludge discharge pipe 601 when the top of the U-shaped sedimentation pipe 2 is not open.

[0032] In use, rainwater flows into the rainwater storage tank body 1. The inclined structure at the bottom of the rainwater storage tank body 1 causes sludge to settle into the U-shaped sedimentation pipe 2. The opening and closing motor 405 drives the worm shaft 406 to rotate, which in turn drives the worm wheel 404 to rotate. The worm wheel 404, through the connecting frame pipe 403, drives the C-shaped rotating pipe 401 to rotate. The C-shaped rotating pipe 401 rotates through the U-shaped sedimentation pipe 2 and the rotating outer shell 402, causing the C-shaped rotating pipe 401 to seal the top of the U-shaped sedimentation pipe 2. The electric valve 602 controls the opening of the sludge discharge pipe 601, and then the sludge is discharged. The sludge motor 501 drives the pulley shaft 502 to rotate. The pulley shaft 502 drives the discharge shaft 503 and the spiral blade 505 to rotate via the synchronous belt 504. This causes the spiral blade 505 to push and discharge the sludge inside the U-shaped sedimentation pipe 2. The sludge is discharged into the storage tank 603 through the discharge pipe 601. Similarly, the electric valve 602 controls the discharge pipe 601 to close, and the C-shaped rotating pipe 401 no longer seals the top of the U-shaped sedimentation pipe 2, allowing the sludge to fall into the U-shaped sedimentation pipe 2 and continue to clean the sludge. This cycle is repeated to discharge the sludge at the bottom of the rainwater storage tank 1.

Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
