Description

Technical Field

[0001] This utility model relates to the field of municipal stormwater and sewage engineering technology, specifically to an intelligent stormwater and sewage diversion device based on redundancy control technology. Background Technology

[0002] In the existing municipal pipeline construction process, rainwater drainage pipes and sewage drainage pipes are laid separately underground. However, in the complex urban environment, due to commercial activities and residents' daily activities, rainwater pipes and sewage pipes are often not distinguished. For example, in the area of ​​street restaurants, some business operators will directly discharge the sewage generated during their business into the rainwater pipes laid on the street, resulting in the sewage collected in the rainwater pipes exceeding the standard.

[0003] Currently, the conventional treatment of rainwater in storm drains involves initial filtration before discharge into rivers. However, if a large amount of domestic sewage from urban areas is present in the storm drains, it leads to the deterioration of the water quality in the rivers, affecting the urban ecological environment. Although public awareness campaigns on sewage treatment in urban catering areas can improve sewage discharge to some extent, a significant portion of sewage still ends up in the storm drains, impacting rainwater treatment. In light of the problems exposed in the actual use of storm drains, it is necessary to implement rainwater and sewage separation in storm drains. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides an intelligent rainwater and sewage separation device based on redundant control technology, which is characterized by facilitating the separation of rainwater and sewage in sewage pipes.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an intelligent rainwater and sewage separation device based on redundant control technology, comprising a rainwater collection well for collecting rainwater, and a rainwater conveying pipe and a sewage conveying pipe horizontally laid in the soil and connected to the rainwater collection well. Connecting pipes are fitted at opposite ends of the rainwater and sewage conveying pipes inside the rainwater collection well. A filter screen is fitted on the connecting pipe. Connecting plates are fixedly fitted at both ends of the filter screen, and the connecting plates are detachably connected to the connecting pipe. A guide rail is provided along the axial direction on the inner wall of the filter screen. A slider that can slide along the direction of the guide rail is fitted on the guide rail. A driven block is fixedly connected to the side of the slider away from the guide rail. Sealing components are provided at both ends of the driven block. When the driven block is displaced, the sealing components seal the rainwater or sewage conveying pipe.

[0006] As a preferred technical solution of the intelligent rainwater and sewage diversion device based on redundancy control technology of this utility model, the sealing component includes an elastic pad disposed at the end of the driven block, a push plate fixedly disposed at the end of the elastic pad away from the driven block, and a sealing protrusion fixedly disposed at the middle of the end of the push plate away from the elastic pad, the sealing protrusion being a protruding hemispherical component.

[0007] As a preferred technical solution of the intelligent rainwater and sewage diversion device based on redundant control technology of this utility model, one end of the guide slide rail is located on the inner wall of the filter screen cylinder and a telescopic rod is fixedly provided. The output end of the telescopic rod is inserted into the interior of the guide slide rail and connected to the end of the slider. The telescopic rod adjusts the position of the slider on the guide slide rail synchronously by adjusting the telescopic displacement of the output end, thereby adjusting the displacement of the driven block.

[0008] As a preferred technical solution of the intelligent rainwater and sewage diversion device based on redundancy control technology of this utility model, the filter screen cylinder is a hollow cylindrical component. The inner wall of the filter screen cylinder is provided with several reinforcing skeletons arranged along the circumferential direction.

The connecting pipe and the connecting plate are connected by threaded engagement.

[0010] As a preferred technical solution of the intelligent rainwater and sewage diversion device based on redundancy control technology of this utility model, a detector is also fixedly installed inside the rainwater collection well, and the detector is electrically connected to the external pipeline network detection equipment.

[0011] As a preferred technical solution of the intelligent rainwater and sewage diversion device based on redundancy control technology of this utility model, the guide slide rail can be set as an arc-shaped component with a certain curvature. The guide slide rail and the filter screen cylinder maintain the same curvature, so that the rainwater conveying pipe and the sewage conveying pipe can have a certain angle.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This technical solution includes a movable driven block. During the displacement of the driven block, the position of the sealing protrusion is adjusted, thereby sealing the ends of the rainwater conveying pipe and the sewage conveying pipe through the sealing protrusion. This allows rainwater or sewage to be discharged through the rainwater conveying pipe and the sewage conveying pipe respectively, thus separating rainwater and sewage in the pipe network, reducing the pressure on downstream sewage treatment, and facilitating the collection and recycling of qualified rainwater. In this technical solution, the aforementioned redundant control technology is used to improve the compatibility between the rainwater pipe and the sewage treatment.

[0014] 2. In this technical solution, a filter screen is installed on the outside of the driven block.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example

[0022] like Figure 1-2 As shown, the intelligent rainwater and sewage separation device based on redundancy control technology of this utility model includes a rainwater collection well 1 for collecting rainwater, and a rainwater conveying pipe 2 and a sewage conveying pipe 3 horizontally laid in the soil and connected to the rainwater collection well 1. Connecting pipes 4 are fitted onto the opposite ends of the rainwater conveying pipe 2 and the sewage conveying pipe 3 inside the rainwater collection well 1. A filter screen cylinder 8 is fitted onto the connecting pipe 4. Connecting plates 6 are fitted and fixed at both ends of the filter screen cylinder 8. The connecting plates 6 are detachably connected to the connecting pipe 4. A guide rail 9 is provided along the axial direction on the inner wall of the filter screen cylinder 8. A slider 10 is fitted with a sliding block 10 that can slide along the guide rail 9. A driven block 13 is fixedly connected to the side of the slider 10 away from the guide rail 9. Both ends of the driven block 13 are equipped with sealing components. When the driven block 13 is displaced, it seals the rainwater conveying pipe 2 or the sewage conveying pipe 3 through the sealing components. In this technical solution, the position of the sealing protrusion 16 is adjusted by adjusting the displacement of the driven block 13, thereby allowing sewage to enter the interior of the rainwater conveying pipe 2 or the sewage conveying pipe 3. The rainwater conveying pipe 2 is connected to the rainwater pipe network, and the sewage conveying pipe 3 is connected to the sewage pipe network, which facilitates the diversion and treatment of rainwater or sewage.

[0023] Specifically, the sealing assembly includes an elastic pad 14 disposed at the end of the driven block 13, a push plate 15 fixedly disposed at the end of the elastic pad 14 away from the driven block 13, and a sealing protrusion 16 fixedly disposed at the middle of the end of the push plate 15 away from the elastic pad 14. The sealing protrusion 16 is a protruding hemispherical component. In this embodiment, the elastic pad 14 provides a certain elasticity to avoid excessive local extrusion pressure when the telescopic rod 11 pushes the slider 10 and the driven block 13, which would cause deformation of the device components. The protruding structure of the sealing protrusion 16 makes it easier to seal the end of the pipe.

[0024] Specifically, one end of the guide rail 9 is fixedly provided with a telescopic rod 11 on the inner wall of the filter cylinder 8. The output end of the telescopic rod 11 is inserted into the interior of the guide rail 9 and connected to the end of the slider 10. The telescopic rod 11 adjusts the position of the slider 10 on the guide rail 9 by adjusting the telescopic displacement of the output end, thereby adjusting the displacement of the driven block 13. In this embodiment, the telescopic rod 11 is electrically connected to the external control equipment, and the telescopic rod 11 can also be connected to the external PLC industrial control equipment. When the detector 12 detects that the sewage data exceeds the standard, the telescopic rod 11 is directly controlled to run through the PLC industrial control equipment, realizing the effect of intelligent separation of rainwater and sewage.

[0025] Specifically, the filter cylinder 8 is a hollow cylindrical component. Several reinforcing frames 7 are arranged along the circumference of the inner wall of the filter cylinder 8. The two ends of the reinforcing frames 7 are connected to the connecting plate 6 to enhance the structural strength of the filter cylinder 8. In this embodiment, the reinforcing frames 7 prevent large external debris from causing excessive compression to the filter cylinder 8, which would damage the filter cylinder 8 and further improve the service life of the equipment.

[0026] Specifically, the connecting pipe 4 is a hollow tubular component that matches the rainwater conveying pipe 2 and the sewage conveying pipe 3. A connecting rod 5 is also provided on the outer surface of the connecting pipe 4. The connecting rod 5 is arranged radially on the outer wall of the connecting pipe 4, which facilitates manual disassembly and assembly of the equipment by the staff. The outer wall of the connecting pipe 4 facing the filter screen cylinder 8 is also provided with threads that cooperate with the connecting plate 6. The connecting pipe 4 and the connecting plate 6 are connected by threaded engagement. In this embodiment, the threaded engagement structure makes it easier for the staff to quickly disassemble and assemble the equipment.

[0027] Specifically, a detector 12 is also fixedly installed inside the rainwater collection well 1. The detector 12 is electrically connected to the external pipeline network detection equipment. In this embodiment, the detector 12 adopts the probe-type COD detector for sewage detection in the prior art. Since this equipment is the prior art, it will not be described in detail in this technical solution.

[0028] Specifically, the guide rail 9 can be set as an arc-shaped component with a certain curvature. The guide rail 9 and the filter screen cylinder 8 maintain the same curvature so that there can be a certain angle between the rainwater conveying pipe 2 and the sewage conveying pipe 3. In this embodiment, it is necessary to consider that in municipal engineering, many rainwater collection wells 1 are small in size or the corresponding pipes have been occupied. It is necessary to set the angle between the rainwater conveying pipe 2 and the sewage conveying pipe 3 at 90°. Therefore, setting the guide rail 9 at a certain angle makes it easier to install the rainwater and sewage separation device.

[0029] The working principle and usage process of this utility model: In the process of using the rainwater and sewage separation device in this utility model, the sewage is detected by the detector 12. When the detected sewage data exceeds the standard, the telescopic rod 11 can be activated. The telescopic rod 11 pushes its telescopic end to change and simultaneously pushes the slider 10 to move inside the guide rail 9. The slider 10 drives the driven block 13 to move synchronously, thereby adjusting the position of the elastic pad 14, the push plate 15 and the sealing protrusion 16. Then, the sealing protrusion 16 blocks the connecting pipe 4 at the end of the rainwater conveying pipe 2, so that the sewage does not flow from the connecting pipe 4 at the end of the rainwater conveying pipe 2 into the rainwater conveying pipe 2. At this time, the connecting pipe 4 at the end of the sewage conveying pipe 3 remains unobstructed, and the sewage is transported to the inside of the sewage conveying pipe 3 through the connecting pipe 4 and then to the sewage treatment plant through the sewage conveying pipe 3.

[0030] When the detector 12 detects that the sewage quality meets the standards, it starts the telescopic rod 11 to operate. The telescopic rod 11 drives the slider 10 to move, which in turn drives the driven block 13 to move toward the connecting pipe 4 at the end of the sewage conveying pipe 3. The sealing protrusion 16 blocks the connecting pipe 4 at the end of the sewage conveying pipe 3. At this time, rainwater is transported and treated through the rainwater conveying pipe 2.

[0031] In the implementation of this technical solution, the filter cylinder 8 is used to filter large particles of foreign matter, preventing foreign matter from entering the interior of the filter cylinder 8 and causing the equipment components to become malfunctioning.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to further limit the present utility model. All equivalent changes made based on the description and drawings of the present utility model are within the protection scope of the present utility model.
