Description

Technical Field

[0001] The utility model relates to the technical field of urban drainage systems, in particular to a rainwater and sewage diversion system. Background Art

[0002] The urban drainage system includes a rainwater and sewage diversion system, which separates rainwater and sewage, allowing rainwater to enter the rainwater pipe network and sewage to be discharged into the sewage treatment plant through the sewage pipe.

[0003] Since the sewage pipe has been positioned during urban construction and its position is difficult to change, the sewage outlet of the rainwater and sewage diversion well may be lower than the sewage pipe, making it difficult for sewage to enter the sewage pipe.

[0004] In summary, when the sewage outlet of the rainwater and sewage diversion well is lower than the sewage pipe, how to make the sewage flow smoothly into the sewage pipe has become an urgent problem to be solved by technical personnel in this field. Utility Model Content

[0005] In order to solve the technical problems in the background technology, the utility model discloses a rainwater and sewage diversion system.

[0006] The utility model provides a rainwater-sewage diversion system, comprising a rainwater-sewage diversion well, whose rainwater outlet is connected to a rainwater collection well through a drainage pipe, and the rainwater collection well is connected to a rainwater pipe network through a pipeline; whose sewage outlet is connected to a water seal well and a sewage collection well in sequence through a sewage pipe, and the sewage collection well is connected to a sewage treatment plant through a pipeline; a sewage lifting well is connected between the rainwater-sewage diversion well and the water seal well;

[0007] Sewage flows into the sewage lifting well;

[0008] A water pump is installed in the sewage lifting well to pump sewage into the sewage collection well.

[0009] The sewage from the rainwater and sewage diversion well is first discharged into the sewage lifting well, and then flows into the sewage collection well through a water pump, so that the sewage can flow smoothly into the sewage pipe, sewage collection well and sewage treatment plant; the setting of the sewage lifting well is not only used for sewage transfer, but also facilitates the installation of water pumps and protects the water pumps to prevent the water pumps from being exposed to the outdoors and easily damaged.

[0010] When the water pump needs to be disassembled or repaired, it is necessary to manually enter the well body, and the operating space is small, which is very inconvenient. Based on this, a further improvement is that the water pump is a coupled water pump. In this way, the water pump can be raised and lowered, and can be disassembled or repaired outside the well body.

[0011] When the amount of sewage is small, the water pump generally does not work. The sludge in the sewage will accumulate at the bottom of the sewage lifting well and harden, causing the water pump inlet to be blocked. Based on this, a further improvement is that an air pipe is installed in the sewage lifting well, and air is supplied by an air pump and blown toward the sludge at the bottom of the sewage lifting well, so that the sludge is mixed with water.

[0012] In order to improve the mixing efficiency of sludge and water, further improvements are as follows: the bottom of the air pipe is connected to an annular pipe distributed at the bottom of the sewage lifting well; a plurality of air holes are arranged on the annular pipe.

[0013] Since the annular tube is relatively light, its position is unstable and it is easy to move, based on this, a further improvement is that a counterweight block is also provided on the annular tube.

[0014] The air pump is generally installed outdoors. In order to keep the air pump running normally, a protective cover needs to be added, which not only takes up more space but also has high costs. Based on this, a further improvement is that the air pump is installed in a distribution cabinet.

[0015] In order to prevent the air pump from affecting the electrical components, a further design is: a partition is installed in the distribution cabinet to divide the distribution cabinet into two cavities; the air pump and the electrical components are installed on both sides of the partition respectively.

[0016] In order to reduce the cost of the distribution cabinet and improve the utilization rate of the partition, a further design is: the electrical components are installed on the partition. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0025] Embodiment 1:

[0026] like Figure 1 As shown, the utility model discloses a rainwater-sewage diversion system, comprising a rainwater-sewage diversion well 1, whose rainwater outlet is connected to a rainwater collection well 3 through a drainage pipe 2, and the rainwater collection well 3 is connected to a rainwater network through a pipeline; its sewage outlet is connected to a water seal well 5 and a sewage collection well 6 in sequence through a sewage pipe 4, and the sewage collection well 6 is connected to a sewage treatment plant through a pipeline.

[0027] A sewage lifting well 7 is connected between the rainwater and sewage diversion well 1 and the water seal well 5. Figure 2 As shown, the sewage outlet is connected to the inlet of the sewage lifting well 7 through a pipeline. A water pump 8 is installed in the sewage lifting well 7 to transport the sewage to the water seal well 5 and the sewage collection well 6 in sequence.

[0028] The water pump 8 adopts a coupled water pump, so that the water pump 8 can be raised and lowered, and can be disassembled or repaired outside the well body, which is simple and convenient to operate.

[0029] The sewage in the rainwater and sewage diversion well 1 is first discharged into the sewage lifting well 7, and then flows into the sewage collecting well 6 through the water pump 8, so that the sewage can smoothly flow into the sewage pipe 4, the sewage collecting well 6 and the sewage treatment plant; the setting of the sewage lifting well 7 is not only used for sewage transfer, but also convenient for the installation of the water pump 8, and plays a protective role for the water pump 8 to prevent the water pump 8 from being exposed to the outdoors and easily damaged.

[0030] Embodiment 2:

[0031] Compared with the first embodiment, the difference is that when the amount of sewage is small, the water pump 8 generally does not work, so the sludge in the sewage will accumulate at the bottom of the sewage lifting well 7 and harden, resulting in the inlet of the water pump 8 being blocked. Therefore, the following design is made: an air pipe 9 is also installed in the sewage lifting well 7, and air is supplied through an air pump 10 installed outside the well body. Figure 4 and Figure 5 As shown, the lower end of the air pipe 9 is provided with an annular pipe 11, which is installed at the bottom of the sewage lifting well 7. The annular pipe 11 is provided with a plurality of air holes 12, and compressed air is ejected from the air holes 12 to loosen the sludge in the well body and mix it with water, so that it can be pumped into the sewage pipe 4 by the water pump 8.

[0032] A plurality of counterweights 13 are also provided on the annular tube 11 to increase the weight of the annular tube 11 so as to make its position in the well body more stable and less likely to move.

[0033] A negative pressure gauge is installed at the inlet of the water pump 8. When the inlet of the water pump 8 is blocked, the negative pressure will increase, thereby controlling the start of the air pump 10; when the negative pressure returns to normal pressure, the air pump 10 is disconnected. In this way, the air pump 10 is automatically turned on and off, which is more efficient.

[0034] Embodiment three:

[0035] Compared with the second embodiment, the difference is that a power distribution cabinet 14 is installed outside the sewage lifting well 7 to control the opening and closing of the air pump 10 and the water pump 8. Figure 3 As shown, a partition 15 is installed in the power distribution cabinet 14 to divide the power distribution cabinet 14 into two cavities. The air pump 10 and the electrical components are installed on both sides of the partition 15. In this way, the air pump 10 is installed in the power distribution cabinet 14, and there is no need to configure a protective cover for the air pump 10 separately, which can reduce the occupied space and reduce the cost. In addition, the partition 15 is set to prevent the air pump 10 from affecting the electrical components.

[0036] The electrical components are mounted on the partition 15 , which can improve the utilization rate of the partition 15 .

[0037] Based on the above ideal embodiments of the utility model, the relevant staff can make various changes and modifications without deviating from the technical concept of the utility model through the above description. The technical scope of the utility model is not limited to the content of the specification, and its technical scope must be determined according to the scope of the claims.
