Description

Technical Field

[0001] The utility model relates to the technical field of diversion wells, in particular to a multifunctional sewage cleaning diversion well. Background Art

[0002] The main function of the clean and dirty diversion well in the urban drainage system is to realize the diversion of rainwater and sewage. In the city, rainwater and domestic sewage are often discharged through the same pipe. In the non-rainy season, there is less sewage and the sewage concentration is high. The sewage flows directly into the sewage pipe through the clean and dirty diversion well and then into the sewage treatment plant. In the rainy season, the rainfall increases significantly, which may cause the sewage treatment plant to be overloaded and increase the impact of rainwater on the sewage treatment plant. At this time, due to the large amount of rainwater, the sewage is quickly carried away and flows into the sewage treatment plant (that is, the initial rainwater is abandoned and the initial rainwater flows into the sewage treatment plant with sewage). When the treatment capacity of the sewage treatment plant reaches the threshold, the sewage concentration is low at this time. The rainwater can be directly transported into other pipes through the clean and dirty diversion well, and flows into other facilities or nearby rivers, so as to reduce the load of the sewage treatment plant.

[0003] In the prior art, the sewage diversion well is also responsible for blocking some tree branches and garbage in the water when it is working. Therefore, after the device is used for a long time, a large amount of garbage is likely to remain in the filter screen and at the bottom of the well. In the prior art, workers generally enter the bottom of the well to deal with it, and entering the bottom of the well is dangerous. Therefore, a multifunctional sewage diversion well is needed to improve this problem. Utility Model Content

[0023] An electric control valve 11 is fixedly arranged between the sewage outlet pipe 3 and the diversion well 1, and the electric control valve 11 can be used to control whether the sewage outlet pipe 3 is connected;

[0024] The upper end of the diversion well 1 is provided with an entrance 12, through which workers can conveniently pull the filter bucket 6 up along the ladder 5;

[0025] A submersible sewage pump 13 is provided inside the diversion well 1; a pressurized water outlet pipe 14 is fixedly provided on one side of the surface of the submersible sewage pump 13. When a flood disaster occurs and the rainwater outlet pipe 4 cannot discharge rainwater in time, the submersible sewage pump 13 can be used to accelerate the discharge of water flow inside the diversion well 1;

[0026] A connecting flange 15 is fixedly provided at one end of the pressurized water outlet pipe 14, and the pressurized water outlet pipe 14 can be conveniently connected to other pipes through the connecting flange 15;

[0028] Working principle: When using this device for normal sewage discharge, sewage can enter the diversion well 1 through the water inlet pipe 2, and then be discharged from the sewage outlet pipe 3. If it rains in the rainy season, in order to reduce the processing pressure of the sewage treatment plant, the sewage outlet pipe 3 is kept to continue to discharge water. When the treatment capacity of the sewage treatment plant reaches the threshold, the control valve is closed to close the sewage outlet pipe. At this time, the amount of sewage in the entire pipeline is very small, and most of it is rainwater. Then, as more and more rainwater overflows the rainwater outlet pipe 4, the rainwater can flow into the river or other institutions through the rainwater outlet pipe 4.

[0029] When the water flows into the diversion well 1, all the water flows out from the filter bucket 6, and the garbage in the water is filtered and remains in the filter bucket 6. When cleaning is needed, the worker does not need to go down the well and can conveniently pull the filter bucket 6 up along the two sides of the ladder 5 through the lifting rope 10, so that the worker can clean the inside of the filter bucket 6 at the upper end of the diversion well 1. In this way, the lifting rope 10 can be tied to the uppermost end of the ladder 5, and it can be untied when it is necessary to pull the filter bucket 6, so that the safety of cleaning of the device can be improved.

[0030] At the same time, when the device is used, the submersible sewage pump 13 can be used to accelerate the discharge of water flow inside the diversion well 1 when a flood disaster occurs and the rainwater outlet pipe 4 cannot discharge rainwater in time.
