Description

Technical Field

[0001] The utility model relates to the technical field of municipal water supply and drainage, and particularly relates to a rainwater and sewage diversion device for urban water supply and drainage. Background Art

[0002] Rainwater is a part of the water resource cycle and is also a very precious water resource. With the continuous development of urbanization construction, the area of impervious roads is increasing day by day. A large amount of rainwater runoff is directly discharged without being utilized, which not only causes a huge waste of water volume, but also increases the burden on urban drainage facilities. Therefore, proper treatment of rainwater can not only save water sources, but also reduce the burden on urban drainage facilities. In daily municipal water supply and drainage projects, people install rainwater and sewage diversion wells to preliminarily filter rainwater to facilitate subsequent treatment of rainwater.

[0003] After retrieval, a patent with the Chinese patent application number 202220341878.1 discloses a rainwater and sewage diversion well with high dredging performance, which relates to the technical field of municipal water supply and drainage. The aim is to solve the problem that the filtering device in the existing rainwater and sewage diversion well will be blocked by sundries, resulting in the well being unable to filter and discharge rainwater, and causing waterlogging on the road surface. The key points of its technical solution are: including a well body, a first grate provided with a plurality of long strip-shaped grooves therein, a plurality of dredging members slidably connected in the vertical direction inside the well body, each of the plurality of dredging members corresponding to a long strip-shaped groove, a force application assembly connected to the dredging members through transmission on the outer peripheral wall of the well body, the force application assembly including a water collection tank slidable in the vertical direction, and a water inlet communicated with the water collection tank is provided on the well body. In the utility model, after the first grate is blocked, rainwater enters the water collection tank along the water inlet, the water collection tank slides down after being filled with water and drives the dredging members to move, so as to dredge the foreign matters on the long strip-shaped grooves, ensuring the drainage performance of the well body;

[0004] The following deficiencies still exist in the above patent during use: after the device is blocked by sundries such as leaves and branches, it can only lift the foreign matters on the long strip-shaped grooves and temporarily dredge the first grate, and cannot thoroughly clean and collect the foreign matters. As time goes by, the foreign matters will still block it, and the cleaning effect is not ideal, affecting the overall rainwater and sewage diversion effect.

[0005] Therefore, there is an urgent need for a rainwater and sewage diversion device for urban water supply and drainage to solve the above problems. Content of the Utility Model

The weight of the water collecting box 41 gradually increases and slides downward. Under the guidance of the second pulley 51 and the first pulley 5 through the steel cable 42, the cleaning frame 33 is pulled, and the foreign matters on the surface of the filter net 31 are gathered through the cleaning rod 34 and the scraping plate 35 and pushed to the discharge port 11. When the cleaning frame 33 carries the support rod 36 and the pressing wheel 37 and contacts the pressing rod 14, the pressing rod 14 is pressed, and the sealing plate 12 is driven to move downward through the connecting rod 13, so that the discharge port 11 is opened. Along with the movement of the cleaning frame 33, the foreign matters are pushed to the collection basket 54 along with part of the rainwater, realizing the automatic cleaning of the foreign matters, increasing the filtering effect of the filter net 31, and improving the efficiency of rainwater and sewage separation. When the water collecting box 41 moves downward, when the third sliding rod 43 contacts the blocking rod 57, along with the continuous movement of the water collecting box 41, the baffle 44 moves upward relative to the water collecting box 41, and the water in the water collecting box 41 is gradually emptied. Through the arranged first tension spring 56 and second tension spring 15, the water collecting box 41 and the sealing plate 12 are pulled back to their original positions.
