Description

Technical Field

[0001] This utility model relates to the field of urban drainage system technology, and in particular to an integrated prefabricated non-siltation intelligent diversion well. Background Technology

[0002] In municipal drainage systems, diversion wells are used to separate rainwater and sewage. Traditional diversion wells have a relatively simple structure, typically relying solely on gravity to allow water of different qualities to flow into different pipes.

[0003] However, in actual operation, diversion wells are prone to clogging. On the one hand, rainwater carries a large amount of silt and debris (such as leaves, branches, and garbage), which easily accumulates in the diversion wells, especially during the rainy season when a large flow of water carrying impurities rushes into the wells, potentially causing blockages in a short time. On the other hand, solid suspended matter and grease in sewage may also accumulate in the diversion wells, affecting the diversion effect.

[0004] When the diversion well is blocked, rainwater cannot be discharged properly, causing urban flooding; sewage cannot flow into the treatment facilities correctly and may overflow and pollute the surrounding environment.

[0005] Currently, some solutions for the problem of siltation in diversion wells mainly involve installing simple filters inside the wells. However, these filters are prone to clogging and lack automatic cleaning capabilities. Once clogged, they require manual cleaning, resulting in high maintenance costs and untimely maintenance. Utility Model Content

[0006] To address the technical issues of existing diversion wells with simple filters that are prone to clogging and lack automatic cleaning functions, requiring manual cleaning once clogged, resulting in high maintenance costs and untimely maintenance, this application proposes an integrated prefabricated non-sludge-collecting intelligent diversion well. By installing a stirring device inside the well, the liquid inside the well is stirred, causing the sludge at the bottom of the well to mix with the liquid and then discharged from the outlet pipe, thereby achieving the technical effect of removing sludge from the well.

[0007] To solve the above-mentioned technical problems, the following technical solution is proposed:

[0013] Furthermore, in this embodiment, a crushing grid is also included, which is disposed at the outlet of the water inlet pipe to intercept and crush large particles of impurities.

[0014] Furthermore, in this embodiment, the stirring device is a gas stirring device.

[0015] Furthermore, in this embodiment, the bottom sides of the well body are provided with slopes, and the slopes on both sides of the bottom of the well body form a flow-gathering groove at the bottom of the well body.

[0016] Furthermore, in this embodiment, a silt detection device is also included. The silt detection device is electrically connected to the control device and is used to detect the silt accumulation in the well body.

[0017] Furthermore, in this embodiment, a water quality testing device is also included. The water outlet pipe includes a first water outlet pipe and a second water outlet pipe. Both the first water outlet pipe and the second water outlet pipe are disposed on the side wall of the well body. The first water outlet pipe is used to connect to a sewage treatment plant, and the second water outlet pipe is used to connect to a natural water body.

[0018] Furthermore, in this embodiment, a level gauge is also included, which is electrically connected to the control device and is used to detect the liquid level height in the well.

[0019] Furthermore, in this embodiment, an anti-buoyancy base is also included, which is disposed at the bottom of the well body.

[0020] Furthermore, in this embodiment, a counterweight chamber is also included, which is disposed at the bottom of the well body and is used to accommodate counterweights of different densities.

[0039] In municipal drainage systems, diversion wells are used to separate rainwater and sewage. Traditional diversion wells have a relatively simple structure, typically relying solely on gravity to allow water of different qualities to flow into different pipes.

[0040] However, in actual operation, diversion wells are prone to clogging. On the one hand, rainwater carries a large amount of silt and debris (such as leaves, branches, and garbage), which easily accumulates in the diversion wells, especially during the rainy season when a large flow of water carrying impurities rushes into the wells, potentially causing blockages in a short time. On the other hand, solid suspended matter and grease in sewage may also accumulate in the diversion wells, affecting the diversion effect.

[0041] When the diversion well is blocked, rainwater cannot be discharged properly, causing urban flooding; sewage cannot flow into the treatment facilities correctly and may overflow and pollute the surrounding environment.

[0042] Currently, some solutions for the problem of siltation in diversion wells mainly involve installing simple filters inside the wells. However, these filters are prone to clogging and lack automatic cleaning capabilities. Once clogged, they require manual cleaning, resulting in high maintenance costs and untimely maintenance.

[0043] To address the technical problems of existing diversion wells with simple filter screens that are prone to clogging and lack automatic cleaning functions, requiring manual cleaning once the screen is clogged, resulting in high maintenance costs and untimely maintenance, this application proposes an integrated prefabricated non-sludge-collecting intelligent diversion well. By installing a stirring device 3 inside the well body 1, the liquid inside the well body 1 is stirred by the stirring device 3, causing the sludge at the bottom of the well body 1 to mix with the liquid and then be discharged from the outlet pipe 6, thereby achieving the technical effect of removing the sludge inside the well body 1.

[0044] like Figure 1 As shown, Figure 1 This application provides a schematic diagram of an integrated prefabricated non-siltation intelligent diversion well. The diversion well includes: a well body 1, a flow limiting valve 2, a stirring device 3, and a control device 4. The well body 1 has a diversion chamber inside, and the side wall of the well body 1 is also provided with an inlet pipe 5 and an outlet pipe 6 that communicate with the diversion chamber. The flow limiting valve 2 is located at the outlet pipe 6 and is used to cut off the flow in the outlet pipe 6. The stirring device 3 is located inside the well body 1 and is used to stir the liquid in the diversion chamber. The flow limiting valve 2 and the stirring device 3 are both electrically connected to the control device 4, and the control device 4 is used to control the flow limiting valve 2 and the stirring device 3.

[0045] For example, such as Figure 3As shown, when silt accumulates in the well body 1, the flow limiting valve 2 is controlled by the control device 4 to limit the flow of water through the outlet pipe 6 and collect water in the well. When the water level reaches the sludge removal mode level, the control device 4 controls the stirring device 3 to start. After the stirring device 3 stirs the liquid in the well body 1, the silt at the bottom of the well body 1 is mixed with the liquid. Then the flow limiting valve 2 is opened, so that the mixture of silt and liquid can be discharged from the outlet pipe 6, thereby achieving the technical effect of removing silt from the well body 1.

[0046] In some embodiments, such as Figure 1 As shown, the diversion well also includes a crushing screen 7, which is installed at the outlet of the inlet pipe 5 to intercept and break up large particles of impurities. It is understood that there may be some large particles of impurities in domestic sewage. These large particles of impurities are heavy and do not mix easily with the liquid. Therefore, in this embodiment, when domestic sewage enters the well body 1 through the inlet pipe 5, it will be intercepted by the crushing screen 7, and the large particles of impurities will be intercepted and broken up into small particles of impurities, so that these impurities can mix with the liquid and be discharged from the outlet pipe 6.

[0047] For example, an exemplary crushing grid 7 is provided in this embodiment. The crushing grid 7 includes two sets of independent blades and a drive device for driving the blades to rotate. Two parallel rotating shafts are provided at the outlet of the water inlet pipe 5. The two sets of blades are respectively arranged on the two rotating shafts. The two sets of blades overlap alternately. The drive device drives the two sets of blades to rotate through the two rotating shafts, thereby cutting large particles of impurities into small particles of impurities.

[0048] In some embodiments, the stirring device 3 is a gas stirring device 3, which sprays high-pressure gas into the diversion chamber to aerate and stir the mud-water mixture in the well body 1.

[0049] In some embodiments, such as Figure 2 As shown, the bottom of the well body 1 is provided with slopes 8 on both sides, and the slopes 8 on both sides of the bottom of the well body 1 form a flow-gathering trough 9 at the bottom of the well body 1. It can be understood that in this embodiment, the cross-section of the bottom of the well body 1 is trapezoidal, and the upper bottom edge of the trapezoidal structure is set towards the bottom of the well body 1. When domestic sewage enters the well body 1 through the inlet pipe 5, the domestic sewage will be gathered at the bottom end of the flow-gathering trough 9 through the slopes 8 on both sides of the bottom of the well body 1, so that the stirring device 3 can more easily handle the sludge in the well body 1.

[0050] In some embodiments, such as Figure 2-3As shown, the diversion well also includes a sludge detection device 10, which is electrically connected to the control device 4. The sludge detection device 10 is used to detect the sludge accumulation in the well body 1. The sludge detection device 10 can monitor the sludge accumulation in the well body 1 in real time and feed the monitoring results back to the control device 4. The control device 4 controls the stirring device 3 and the flow limiting valve 2 to remove the sludge in the well body 1 in a timely manner through the feedback structure of the sludge detection device 10.

[0051] For example, the silt detection device 10 can be a high-definition waterproof camera or an ultrasonic liquid (mud) level gauge. The high-definition waterproof camera can monitor the image data inside the well in real time. By analyzing the image data, information inside the well body 1 can be obtained, thereby obtaining the silt accumulation situation inside the well body 1. The ultrasonic liquid (mud) level gauge can obtain the silt accumulation situation inside the well body 1 by checking the height change inside the well body 1.

[0052] In some embodiments, such as Figure 2-3 As shown, the diversion well also includes a water quality testing device 11. The outlet pipe 6 includes a first outlet pipe 6 and a second outlet pipe 6. Both the first outlet pipe 6 and the second outlet pipe 6 are installed on the side wall of the well body 1. The first outlet pipe 6 is used to connect to a sewage treatment plant, and the second outlet pipe 6 is used to connect to a natural water body. Both the first outlet pipe 6 and the second outlet pipe 6 are equipped with flow limiting valves 2. The water quality testing device 11 is installed in the diversion chamber and is used to detect the water quality data in the diversion chamber. The water quality testing device 11 is electrically connected to the control device 4. The control device 4 controls the flow limiting valves 2 according to the detection results of the water quality testing device 11.

[0053] For example, during rainy weather, initial rainwater dissolves acidic gases (such as sulfur dioxide and nitrogen oxides), vehicle exhaust particles, and industrial waste gases from the air. Simultaneously, it carries pollutants such as road surface oil, heavy metals (lead, zinc, and copper), pesticide residues, and tire wear particles as it washes over the ground. The chemical oxygen demand (COD), suspended solids (SS), and total phosphorus (TP) levels of initial rainwater may exceed those of ordinary urban sewage by several times, even directly threatening aquatic life and human health. Therefore, initial rainwater needs to be intercepted and treated at a sewage treatment plant. Thus, when the water quality monitoring device 11 detects that the liquid level in well 1 exceeds a preset threshold, the control device 4 determines that it is the initial stage of rainfall and controls the flow-limiting valve 2 of the first outlet pipe 6 to open and the flow-limiting valve 2 of the second outlet pipe 6 to close, allowing the initial rainwater to be intercepted through the first outlet pipe 6 and discharged into the municipal sewage network for treatment at the sewage treatment plant.

[0054] During the later stages of rainfall, the amount of exhaust gas and ground pollutants in the air is greatly reduced, and the amount of pollutants in the rainwater flowing into the well body 1 is also greatly reduced. Therefore, when the water quality detection device 11 detects that the detection result of the liquid in the well body 1 does not exceed the preset threshold, the control device 4 determines that it is in the later stages of rainfall and controls the flow limiting valve 2 of the first water outlet pipe 6 to close and the flow limiting valve 2 of the second water outlet pipe 6 to open, so that the rainwater in the later stages of rainfall can be directly discharged into the natural water body through the second water outlet pipe 6.

[0055] In some embodiments, such as Figure 2-3 As shown, the diversion well also includes a level gauge 12, which is electrically connected to the control device 4. The level gauge 12 is used to monitor the liquid level in the well body 1. By monitoring the liquid level in the well body 1 through the level gauge 12, the opening and closing of the flow limiting valve 2 of the first water outlet pipe 6 and the second water outlet pipe 6 are controlled, thereby controlling the liquid level in the well body 1.

[0056] In some embodiments, such as Figure 1-2 As shown, the diversion well also includes an anti-buoyancy base 13. The anti-buoyancy base 13 is used to solve the stability problem of underground structures caused by the buoyancy of groundwater. By placing the anti-buoyancy base 13 at the bottom of the well body 1, the buoyancy is offset by increasing self-weight (such as concrete counterweight) or anchoring measures (such as anchor rods or pile foundations), ensuring structural stability. Secondly, the anti-buoyancy base 13 is rigidly connected to the bottom of the well body 1, which can improve the overall strength and deformation resistance of the well body 1 and reduce the risk of uneven settlement.

[0057] In some embodiments, such as Figure 2 As shown, the diversion well also includes a counterweight chamber 14, which is located at the bottom of the well body 1 and is used to hold counterweights of different densities. By adjusting the weight of the counterweights in the counterweight chamber 14, the anti-buoyancy capability of the anti-buoyancy base 13 can be changed, thereby enabling the diversion well to adapt to the usage requirements of different geological environments.

[0058] In some embodiments, such as Figure 1 As shown, the outer wall of the well body 1 is also provided with lifting lugs 15, which make it easier for workers to lift the equipment.

[0059] It should be noted that this application is not limited to the above-described embodiments. The above embodiments are merely examples, and any embodiments with the same structure and effect as the technical concept within the scope of this application are included in the technical scope of this application. Furthermore, various modifications that can be conceived by those skilled in the art to the embodiments, and other ways of constructing by combining some of the constituent elements of the embodiments, without departing from the spirit of this application, are also included in the scope of this application.
