Description

Technical Field

[0001] This utility model relates to an interception well, belonging to the field of sewage treatment technology. Background Technology

[0002] In the field of wastewater treatment technology, intercepting wells, as important sewage interception and control facilities, have the core function of achieving efficient separation and interception of rainwater and sewage through dynamic adjustment. This is especially crucial during the rainy season or when there is a sudden surge in flow, requiring a rapid response to balance pipeline pressure and prevent sewage overflow. Flexible intercepting wells, due to their flexible structure and high adjustability, are gradually becoming the mainstream technology. Existing flexible intercepting wells mostly employ pneumatic or mechanical control methods, such as adjusting the interception flow rate by changing the opening of the interception port through the expansion and contraction of the air chamber.

[0003] However, in practical applications, the current chamber design of existing technologies, which uses single-point supply and exhaust, results in insufficient real-time feedback capability of the system, making it difficult to meet the dynamic operating conditions in terms of response speed. Chinese invention patent CN111197347A, "Flexible Interception Device and Diversion Well," describes a flexible interception device, comprising: an elastic sleeve with a flow channel; and an outer cover disposed outside the elastic sleeve. The two ends of the elastic sleeve are detachably sealed to the two ends of the outer cover, and an air cavity is formed between the inner wall of the outer cover and the outer wall of the elastic sleeve. The air cavity has air holes. When pressurized gas is injected into the air cavity, the elastic sleeve deforms, and the cross-sectional area of ​​the flow channel decreases.

[0004] The aforementioned patents still have unresolved issues. For example, when rainfall intensity increases sharply, because multiple chambers need to be supplied and vented simultaneously, the control actions of existing intercepting wells often lag behind changes in flow rate, making it impossible to quickly adapt and adjust interception parameters. This delay may lead to decreased interception efficiency, pipeline pressure imbalance, and even the risk of sewage overflow. On the other hand, the pneumatic systems of traditional intercepting wells, due to centralized air supply or single-chamber control, can cause uneven local pressure distribution, further exacerbating the response lag problem.

[0005] Therefore, a diversion well is proposed. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of the existing technology and solve the problems of slow feedback speed and uneven local pressure distribution of existing products under complex working conditions.

[0007] To solve the above-mentioned technical problems, this utility model is implemented using the following technical solution:

[0008] A diversion well is provided, including a well body; the sidewalls of the well body are arranged in a ring array of air-filled chambers; a clamp is provided in the air-filled chamber, and the air-filled chamber is divided into a first chamber and a second chamber through the clamp;

[0009] The inner wall of the first chamber is provided with fixing ribs, which are arranged in a ring array around the axis of the well body; an isolation plate is installed at the clamping plate opposite to each fixing rib, and the surface of the isolation plate is provided with a notch for gas to pass through. The first chamber is divided into sub-chambers by radially separated isolation plates.

[0010] The surface of the isolation plate is fitted with a movable plate, and the size of the notch in the isolation plate can be changed by the axially moving movable plate.

[0011] An air pump is installed in the second chamber, and the air pump supplies air to the first chamber through an air inlet.

[0012] Furthermore, the movable plate and the isolation plate have the same structure and overlap in a horizontal view. One end of the movable plate is connected to a telescopic component, and the movable plate moves axially through the telescopic component.

[0013] Furthermore, one end of the isolation plate is fixedly connected to the clamping plate, and the other end is attached to the fixing rib; the notches are arranged in a linear array along the axial direction of the well body.

[0014] Furthermore, the clamping plate is placed coaxially with the well body, and the distance from the inner side of the clamping plate to the inner wall of the first chamber is the same as the distance from the outer side of the clamping plate to the outer wall of the second chamber.

[0015] Furthermore, the isolation plates are configured in three parts, and each of the sub-chambers has an air inlet on its outer wall.

[0016] Furthermore, there are three air pumps, each connected to an air inlet and radially installed in the second chamber.

[0017] Furthermore, the inner wall of the first chamber is made of wear-resistant and corrosion-resistant rubber.

[0018] Furthermore, a buffer ring is provided on the outer wall of the air-filled chamber, and the buffer ring is arranged linearly along the axis of the well body.

[0019] Compared with the prior art, the beneficial effects achieved by this utility model are as follows:

[0020] Compared with existing technologies, this invention features a design with annular array of air-filled chambers and clamping plates on the well body sidewalls. The fixed ribs and isolation plates in the first chamber form radially separated sub-chambers. The size of the gap can be adjusted by the axial movement of the movable plate, making the gas delivery path more independent and controllable, thus avoiding the pressure transmission delay problem caused by traditional centralized gas supply. At the same time, the adjustment of the movable plate and isolation plate can dynamically adjust the gas passage area, thereby adapting to different flow requirements in real time and significantly shortening the control response time.

[0029] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention.

[0030] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] like Figure 1 As shown, a diversion well is provided, including a well body 1; the sidewalls of the well body 1 are arranged in a ring array of air-filled chambers 2; a clamping plate 21 is provided inside the air-filled chambers 2, and the air-filled chambers 2 are divided into a first chamber 22 and a second chamber 23 through the clamping plate 21;

[0032] like Figure 2 and Figure 4 As shown, the inner wall of the first chamber 22 is provided with fixing ribs 221, wherein the fixing ribs 221 are made of rigid material, thereby fixing the side wall of the first chamber 22 near the axis of the well body 1, and forming multiple sub-chambers 24 in conjunction with the isolation plate 222; the fixing ribs 221 are arranged in a ring array around the axis of the well body 1; an isolation plate 222 is installed at the clamping plate 21 opposite to each fixing rib 221, and the surface of the isolation plate 222 is provided with a notch 223 for gas to pass through. The first chamber 22 is divided into sub-chambers 24 by the radially separated isolation plates 222; a movable plate 224 is attached to the surface of the isolation plate 222, and the size of the notch 223 is changed by the axially moving movable plate 224; specifically, the movable plate 224 and the isolation plate 222 have the same structure and coincide in the horizontal view, and one end of the movable plate 224 is connected to a telescopic member 225. The movable plate 224 moves axially through the telescopic member 225, thereby realizing the size change of the notch.

[0033] like Figure 3 As shown, the movable plate 224 and the partition plate 222 are fitted together, and both surfaces are provided with notches 223 of the same size. When the telescopic member 225 extends or retracts, this embodiment preferably uses a cylinder. The cylinder is electrically connected to the central control platform, and the extension or retraction amount is adjusted in real time by the central control platform, thereby driving the movable plate 224 to move axially. When the cylinder extends or retracts to its maximum length, the movable plate 224 and the partition plate 222 close each other, so that the movable plate 224 and the partition plate 222, which are fitted together at a frontal viewing angle, can block each other, thereby sealing the adjacent sub-chambers 24. The system is closed, allowing each air pump 231 to respond quickly during air delivery, meaning each sub-chamber 24 can be individually air-intaken, improving the feedback speed of the flexible interception well in rainy weather. It should be noted that the baffle structure formed by the isolation plate 222 and the movable plate 224 creates a dynamic seal between adjacent sub-chambers 24. Combined with the pressure between adjacent sub-chambers 24, dynamic balance can be achieved. Therefore, the structural strength of the isolation plate 222 and the movable plate 224 can be achieved using steel or copper plates, and they can also assist in pressure equalization by separating the sub-chambers 24.

[0034] like Figure 5 As shown, an air pump 231 is installed in the second chamber 23, and the air pump 231 supplies air to the first chamber 22 through the air inlet 241; in this embodiment, Figure 2The image shows a support column covering the surface of a micro air pump. This support column can share some of the vertical pressure and provide space for the micro air pump. The air pump 231 is then installed in the second chamber 23 via the support column, separating it from the high-pressure gas in the first chamber 22. It supplies air to each sub-chamber 24 through the air inlet 241. The air pump 231 regulates the air supply volume through a central control platform. The air supply volume is calculated synchronously with the pressure and volume gauges in the flexible interception well to obtain a precise air supply volume, thereby preventing excessive or insufficient expansion of the chambers. The actual sampling data can all be provided by sensors.

[0035] One end of the isolation plate 222 is fixedly connected to the clamping plate 21, and the other end is attached to the fixing rib 221. Specifically, the inner wall of the first chamber 22 is set as a flexible structure, so a part of the first chamber 22 needs to be bonded to the fixing rib 221. In actual use, stainless steel pressure strips or plastic clamps can be used to fix the edges of the bonding area, and sealant can be used to fill the gaps. Alternatively, corrosion-resistant and fatigue-resistant adhesives such as neoprene rubber and polyurethane can be used. The notches 223 are arranged in a linear array along the axial direction of the well body 1. Since it is necessary to control the gas flow of adjacent sub-chambers 24 according to the drainage volume, one end of the isolation plate 222 is installed on the clamping plate 21, and the other end is attached to the fixing rib 221. Since the fixing rib 221 is a non-flexible structure, when each sub-chamber 24 expands, the position of the fixing rib 221 is always attached to the isolation plate 222, thereby achieving the separation of the sub-chambers 24.

[0036] like Figure 6 As shown, the isolation plate 222 can adjust the telescopic component 225 during rapid air supply, thereby sealing the three sub-chambers 24 to achieve uniform pressure distribution and rapid inflation. At the same time, in the event of a failure of a certain air pump 231, such as when the pressure sensor in the flexible interception well detects an abnormal pressure in a certain sub-chamber 24, i.e., too high or too low, the gap 223 can be opened to temporarily supplement the air supply to the sub-chamber 24 through the adjacent air pump 231, providing short-term temporary use time, thereby giving maintenance time and reducing the probability of emergency repairs under severe working conditions.

[0037] The clamping plate 21 is placed coaxially with the well body 1, and the distance from the inner side of the clamping plate 21 to the inner wall of the first chamber 22 is the same as the distance from the outer side of the clamping plate 21 to the outer wall of the second chamber 23. The clamping plate 21 divides the air-filling chamber 2 radially and evenly, which protects the service life of the air pump 231 and reduces damage to the inner wall of the first chamber 22.

[0038] like Figure 4As shown, in this embodiment, there are three isolation plates 222, and under the separation of the isolation plates 222, there are also three sub-chambers 24. There are three air pumps 231, and each air pump 231 is connected to an air inlet 241 and is radially installed in the second chamber 23. Under the condition of ensuring that each air pump 231 has the same air delivery rate, each sub-chamber 24 is supplied with air by a separate air pump 231, and each sub-chamber 24 has an air inlet 241 on its outer wall.

[0039] The inner wall of the first chamber 22 is made of wear-resistant and corrosion-resistant rubber material, which is used to expand according to sensor data under different weather conditions, thereby achieving different degrees of flow interception.

[0040] The outer wall of the air-filled chamber 2 is provided with a buffer ring 3, which is arranged linearly along the axis of the well body 1 to reduce rigid collisions with the outer wall of the air-filled chamber 2 and improve stability.

[0041] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
