Description

Technical Field

[0001] The utility model relates to the technical field of municipal drainage pipelines, and specifically relates to a municipal drainage diversion device. Background Technique

[0002] When it rains, a large amount of water will flow into the municipal drainage pipeline. If all the rainwater is transported to the sewage treatment plant, the treatment pressure of the sewage treatment plant will be too high, and most of the rainwater is clean rainwater and does not need to be treated.

[0003] According to the search, the Chinese patent document, publication number: CN210737727U, discloses a municipal drainage diversion device. By setting a control mechanism, as the rainfall increases, the water level in the rain-sewage separation cylinder will rise to automatically judge whether the water flowing into the rain-sewage separation cylinder is sewage or clean rainwater, and then cooperate with the diversion mechanism to realize the diversion and transportation of sewage and rainwater, eliminating the inconvenience of manual control and being relatively convenient. A filter screen is provided in the water inlet pipe to filter out larger impurities brought into the water inlet pipe by the water flow, preventing larger impurities from entering the rain-sewage separation cylinder and affecting the operation of the control mechanism or the diversion mechanism. However, during the use process, when the water enters the separation cylinder and generates buoyancy on the floating ball to drive the gear set to switch the diversion, since the gear set is immersed in sewage, it is easy to be blocked when the floating ball drives the rotating shaft to rotate, resulting in a smaller diversion opening, thus reducing the drainage efficiency and easily causing a smaller diversion drainage volume. At the same time, when the connecting pipe is damaged, it is troublesome and time-consuming to replace, and it is easy to delay the drainage progress. Content of the Utility Model

Connecting cylinders 9 are respectively fixedly installed on the left and right sides of the diversion box 1. A connecting head 10 is installed inside the connecting cylinder 9 through clamping. A water inlet pipe 11 is fixedly installed at the rear of the diversion box 1.

[0032] Specifically, drainage plates 101 are fixedly installed on the left and right sides inside the diversion box 1. Flow holes 102 are formed on the right side of the drainage plates 101. The flow holes 102 are grouped in threes and are arranged in a circular and equally spaced manner on the outside of the drainage plates 101. The advantage is that through the flow holes 102 on the drainage plates 101, it is beneficial to facilitate drainage. At the same time, by controlling the opening and closing of the flow holes 102, it is convenient to achieve drainage diversion.

[0033] Specifically, an installation cavity 201 is formed inside the fixed box 2. Sliding grooves 202 are respectively formed on the top and bottom sides inside the installation cavity 201. Sliders are arranged inside the sliding grooves 202. A fixed frame 5 is fixedly installed on the side of the slider away from the sliding groove 202. The advantage is that through the two groups of sliding grooves 202 and sliders, it is beneficial to conduct orientation and limit during the process of the flow control plate 6 pushing the fixed frame 5 to move, thereby improving the stability of the fixed frame 5 during movement and extending the service life of the device.

[0034] Specifically, the fixed frame 5 has a U-shaped structure, and a groove 501 is formed on the bottom side inside the fixed frame 5. A rack 502 is fixedly installed inside the groove 501. The rack 502 is meshed with the idler gear 4, and a return spring is fixedly installed between the left side of the fixed frame 5 and the installation cavity 201. The advantage is that the rack 502 drives the idler gear 4, the transmission gear 3, and the fixed rod 7 to rotate. Since the two drainage plates 101 are installed in an interleaved manner, when the fixed rod 7 drives the flow blocking plate 8 to rotate, the flow holes 102 on one of the drainage plates 101 are completely opened, and the flow holes 102 on the other drainage plate 101 are completely closed, thereby completing drainage diversion and automatically performing drainage diversion without manual operation.

[0035] Embodiment 2:

[0036] As Figures 1-6 shown, as an improvement over the previous embodiment. Specifically, a card slot 901 is formed on the side of the connecting cylinder 9 away from the diversion box 1. The size and shape of the card slot 901 match those of the connecting head 10, and external threads are formed on the outside of the connecting cylinder 9. The advantage is that through the card slot 901, it is convenient to position and install the connecting head 10 when installing the discharge pipe, improving the installation efficiency. At the same time, due to the external threads formed on the outside of the connecting cylinder 9, it is beneficial to reinforce the connecting head 10 and improve the stability.

[0037] Specifically, the connector 10 includes a clamping tube 1001, a connecting tube 1002, a limiting ring 1003 and a connecting threaded sleeve 1004.

At this time, when the limiting ring 1003 moves, it pushes the clamping tube 1001 to move, which is beneficial to increasing the clamping strength of the connection end, and the installation is convenient and fast.

[0038] When in use, one end of the discharge pipe is fixedly welded to the connecting tube 1002, then the left end of the clamping tube 1001 is engaged with the clamping groove 901, then the connecting threaded sleeve 1004 is rotated to drive the limiting ring 1003 to move, and then the connecting threaded sleeve 1004 is connected and fixed under the action of the external thread. At this time, when the limiting ring 1003 moves, it pushes the clamping tube 1001 to move, which is beneficial to increasing the clamping strength of the connection end. When disassembling and replacing, just rotate the connecting threaded sleeve 1004 to pull out the clamping tube 1001. The installation is convenient and fast. And during the drainage process, when the rainfall is small, the rainwater enters the diversion box 1 through the water inlet pipe 11, and then flows through the gap between the flow control plate 6 and the diversion box 1 to the water flow hole 102 and is discharged through the discharge pipe. When the rainfall increases, the rainwater entering the interior of the diversion box 1 impacts the flow control plate 6, causing the fixed frame 5 to move. Then the rack 502 drives the idler gear 4, the transmission gear 3 and the fixed rod 7 to rotate. Since the two drainage plates 101 are installed alternately, when the fixed rod 7 drives the baffle 8 to rotate, the water flow holes 102 on one of the drainage plates 101 are completely opened, and the water flow holes 102 on the other drainage plate 101 are completely closed, thus completing the drainage diversion. The automatic drainage diversion does not require manual operation, and the drainage effect is good. The overall structure is stable. Then when the rainfall decreases, under the action of the spring, the fixed frame 5, the flow control plate 6 and the baffle 8 are reset to restore the normal discharge amount. The use is convenient and simple.
