Description

Technical Field

[0001] This invention relates to the field of interception well technology, and in particular to a smart interception well structure with flow regulation and backflow prevention functions. Background Technology

[0002] With societal development, water environment issues have become increasingly prominent. Traditional intercepting wells can no longer meet the requirements of complex operating conditions, leading to the development of different types of conventional intercepting wells within the industry. However, conventional intercepting wells still present the following problems in actual operation: Intercepting wells are often used in conjunction with regulating reservoirs for water pollution control and flood prevention. When equipment malfunctions in the regulating reservoir or continuous rainfall leads to insufficient regulating capacity, intercepted sewage may have nowhere to go for a short period, eventually overflowing into natural water bodies and polluting the environment. When the outlet is a submerged outflow and the water level difference between the intercepting well and the normal water level of the external river is large, conventional intercepting wells cannot meet the water level difference requirements, which may lead to river backflow.

[0003] The applicant's patent application (202223046693.7) describes a smart intercepting well with flow regulation and backflow prevention functions. It includes a well body, an inlet pipe, an intercepting pipe, an outlet pipe, an electrically controlled flow regulating gate, a floating weir, and a control box. The well body has a weir wall that divides the internal space into an inner and outer space. The weir wall has an overflow hole and a drain hole, with the drain hole located above the overflow hole. The inlet and intercepting pipes connect to the inner space, and the outlet pipe connects to the outer space. The electrically controlled flow regulating gate is positioned corresponding to the intercepting pipe, and the floating weir is positioned corresponding to the overflow hole and located in the outer space. The electrically controlled flow regulating gate is electrically connected to the control box. This design enables flow regulation and prevents backflow. However, the floating weir is unstable when not in use and is prone to swaying due to water flow impact, which can lead to long-term damage.

[0004] In view of this, a smart interception well structure with flow regulation and backflow prevention functions is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a smart interception well structure with flow regulation and backflow prevention functions, which enables the floating weir to remain stable when not in use.

[0006] The above-mentioned technical objective of the present invention is achieved through the following technical solution:

[0007] A smart intercepting well structure with flow regulation and backflow prevention functions includes a well body, an inlet pipe, an intercepting pipe, an outlet pipe, an electrically controlled flow regulating gate, a floating weir, and a control box. The well body has a weir wall that divides the internal space of the well body into an inner space and an outer space. The weir wall has an overflow hole and a drain hole, with the drain hole located above the overflow hole. The inlet pipe and the intercepting pipe connect to the inner space, and the outlet pipe connects to the outer space. The electrically controlled flow regulating gate is positioned corresponding to the intercepting pipe. The floating weir includes a weir body and a receiving component. One end of the weir body is rotatably connected to the weir wall. The receiving component includes a support and a receiving body. The support is located in the outer space, and the receiving body is mounted on the support. The receiving body has a receiving groove for receiving the floating weir. The weir body is positioned corresponding to the overflow hole and located in the outer space. The electrically controlled flow regulating gate is electrically connected to the control box.

[0008] In a preferred embodiment, the receiving body includes a first petal and a second petal, the ends of the first petal and the second petal are rotatably connected to the bracket, the receiving groove is formed between the first petal and the second petal, and the interiors of the first petal and the second petal are hollow.

[0009] In a preferred embodiment, one end of the first valve body is provided with a first rotating shaft, the bracket is provided with a first shaft hole that cooperates with the first rotating shaft, the side of the first shaft hole is provided with a first limiting groove, and the first rotating shaft is provided with a first limiting block that is inserted into the first limiting groove. One end of the second valve body is provided with a second rotating shaft, the bracket is provided with a second shaft hole that cooperates with the second rotating shaft, the side of the second shaft hole is provided with a second limiting groove, and the second rotating shaft is provided with a second limiting block that is inserted into the second limiting groove.

[0010] In a preferred embodiment, a flexible pad is provided on the inner surface of the first and second valve bodies, the flexible pad being made of rubber or foam material.

[0011] In a preferred embodiment, the first petal body is provided with a first limiting edge extending toward the receiving groove, and the second petal body is provided with a second limiting edge extending toward the receiving groove.

[0012] In a preferred embodiment, the well body and the weir wall are made of concrete.

[0013] In a preferred embodiment, a grille is provided in the inner space, and the grille is provided corresponding to the overflow hole.

[0014] In a preferred embodiment, a submersible pump is provided in the inner space, and the submersible pump is electrically connected to the electrical control box.

[0015] In a preferred embodiment, the system further includes a level gauge and a rain gauge, with the level gauge respectively disposed in the inner space and the outer space, and the level gauge and the rain gauge being electrically connected to the control box.

[0016] Compared with existing technologies, this invention provides a smart intercepting well structure with flow regulation and backflow prevention functions. By improving the structure of the floating weir, the floating weir remains stable in the non-use state, thus avoiding damage in an unstable state. Specifically, in the non-use state, there is no water in the outer space, the weir body has no buoyancy to rely on, and it is located in the receiving groove. When the overflow hole drains water from the inner space to the outer space, although it impacts the floating weir, the bearing force of the receiving body keeps the floating weir stable, thus preventing it from swaying and being damaged by the impact of the water flow, thereby protecting the weir body. At the same time, when the floating weir closes and completes the backflow prevention function, the receiving body supports the weir body when it falls, which also prevents damage to the weir body.

[0017] More comprehensively, under the configuration of this invention, the electrically controlled flow regulating gate can control the interception flow rate according to the liquid level in the inner space of the interception well. The higher the liquid level in the inner space, the smaller the opening angle of the electrically controlled flow regulating gate, thereby keeping the interception flow rate constant. The floating weir is fully open during non-rainy periods or at the beginning of rainfall. When the liquid level in the inner space exceeds the overflow hole, water can overflow through the open weir. At the same time, because the weir is installed in a high position, the overflow liquid level can be raised, thereby reducing the frequency of overflow. When the coupled regulating tank is full or the intercepted sewage... When water has nowhere to go, the intercepting well and the surplus space of the upstream pipeline network are used for storage, extending the time before overflow occurs, thereby reducing the frequency of overflow and thus reducing overflow pollution. When the water level of the outer river rises, causing the liquid level in the outer space to rise, the weir can rise along with the external liquid level, thereby ensuring the safety of the inner side of the intercepting well. The spillway is used for flood discharge. When the liquid level in the inner space continues to rise and the overflow hole opening can no longer meet the flood discharge requirements, the inner space can drain water immediately through the spillway. The control box is used to control the relevant electrical components. Attached Figure Description

Detailed Implementation

[0026] The present invention will be further described in detail below with reference to the accompanying drawings.

[0027] This specific embodiment is merely an explanation of the present invention and is not intended to limit the invention. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.

[0028] like Figures 1 to 6As shown, a smart intercepting well structure with flow regulation and backflow prevention functions includes a well body 1, an inlet pipe 7, an intercepting pipe 8, an outlet pipe 9, an electrically controlled flow regulating gate 10, a floating weir, and a control box 12. The well body 1 has a weir wall 2, dividing the internal space of the well body 1 into an inner space 3 and an outer space 4. The weir wall 2 has an overflow hole 5 and a drain hole 6, with the drain hole 6 located above the overflow hole 5. The inlet pipe 7 and the intercepting pipe 8 connect to the inner space 3, and the outlet pipe 9 connects to the outer space 4. The electrically controlled flow regulating gate 10... As per the interception pipe configuration, the floating weir includes a weir body 110 and a receiving assembly. One end of the weir body 110 is rotatably connected to the weir wall 2. The receiving assembly includes a support 111 and a receiving body 114. The support 111 is located in the outer space 4, and the receiving body 114 is located on the support 111. The receiving body 114 has a receiving groove 119 for receiving the floating weir. The weir body 110 is configured corresponding to the overflow hole 5 and is located in the outer space 4. The electrically controlled flow regulating gate 10 is electrically connected to the control box 12.

[0029] This embodiment presents a smart intercepting well structure with flow regulation and backflow prevention functions. By improving the structure of the floating weir, the floating weir remains stable in the non-use state, thus avoiding damage in an unstable state. Specifically, in the non-use state, there is no water in the outer space 4, the weir body 110 has no buoyancy to rely on, and it is located in the receiving groove 119. When the overflow hole 5 drains water from the inner space 3 to the outer space 4, although it impacts the floating weir, the bearing force of the receiving body 114 keeps the floating weir stable, thus preventing it from swaying and being damaged by the water flow, thereby protecting the weir body 110. At the same time, when the floating weir closes and completes the backflow prevention function, the receiving body 114 supports the weir body 110 when it falls, which also prevents damage to the weir body 110.

[0030] Its electrically controlled flow regulating gate 10 can control the interception flow rate based on the liquid level in the inner space 3 of the interception well. The higher the liquid level in the inner space 3, the smaller the opening angle of the electrically controlled flow regulating gate 10, thus keeping the interception flow rate constant. The floating weir is fully open during non-rainy periods or at the beginning of rainfall. When the liquid level in the inner space 3 exceeds the overflow hole 5, drainage can be discharged through the open weir body 110. At the same time, because the weir body 110 is installed in a high position, the overflow liquid level can be raised, thereby reducing the frequency of overflow. When the coupled regulating tank is full or the intercepted sewage has nowhere to go, it can utilize... The intercepting well and the surplus space of the upstream pipeline are used to regulate and store water, prolonging the time before overflow occurs, thereby reducing the frequency of overflow and thus reducing overflow pollution. When the water level of the outer river rises, causing the liquid level in the outer space 4 to rise, the weir 110 can rise with the rise of the external liquid level, thereby ensuring the safety of the inner side of the intercepting well. The drain hole 6 is used for flood discharge. When the liquid level in the inner space 3 continues to rise, the opening of the overflow hole 5 can no longer meet the flood discharge requirements, and the inner space 3 can drain water immediately through the drain hole 6. The control box 12 is used to control the relevant electrical components.

[0031] Furthermore, the receiving body 114 includes a first petal 115 and a second petal 118. The ends of both the first petal 115 and the second petal 118 are rotatably connected to the bracket 111. A receiving groove 119 is formed between the first petal 115 and the second petal 118. The interiors of the first petal 115 and the second petal 118 are hollow. With this structural arrangement, when the water level in the outer space 4 is low, the first petal 115 and the second petal 118 are not subject to buoyancy. Under their natural gravity, their lower ends hang down naturally, causing their tops to come together and clamp the weir 110, thus keeping the weir 110 stable. When the water level is high, the first petal 115 and the second petal 118 are subject to buoyancy, and the gravity at their lower parts is offset, causing the tops to open, allowing the weir 110 to rise under the action of buoyancy.

[0032] To limit the rotation angle of the first petal 115 and the second petal 118, control the opening distance between the bottoms of the first petal 115 and the second petal 118, and achieve support for the weir body 110, a first rotating shaft 116 is provided at one end of the first petal 115. The bracket 111 is provided with a first shaft hole 112 that cooperates with the first rotating shaft 116. A first limiting groove 113 is provided on the side of the first shaft hole 112. A first limiting block 117 that is inserted into the first limiting groove 113 is provided on the first rotating shaft 116. A second rotating shaft is provided at one end of the second petal 118. A second shaft hole that cooperates with the second rotating shaft is provided on the bracket 111. A second limiting groove is provided on the side of the second shaft hole. A second limiting block that is inserted into the second limiting groove is provided on the second rotating shaft.

[0033] In order to prevent damage when the weir 110 falls, a flexible pad is provided on the inner surface of the first petal 115 and the second petal 118, the flexible pad being made of rubber or foam material.

[0034] In order to effectively limit the weir body 110, the first petal body 115 is provided with a first limiting edge extending in the direction of the receiving groove 119, and the second petal body 118 is provided with a second limiting edge extending in the direction of the receiving groove 119.

[0035] Specifically, the well body 1 and the weir wall 2 are made of concrete.

[0036] Furthermore, a grille is provided in the inner space 3, and the grille is set corresponding to the overflow hole 5. The grille can intercept suspended or floating objects in the water.

[0037] Furthermore, a submersible sewage pump is installed in the inner space 3. The submersible sewage pump is electrically connected to the electrical control box. When the rainstorm intensity is high and the river water level is too high to be discharged by gravity, it can be combined with the pumping station to assist the rainwater lifting pumping station in drainage.

[0038] This embodiment of a smart intercepting well with flow regulation and backflow prevention functions also includes a level gauge 13 and a rain gauge 14. The level gauge 13 is respectively installed in the inner space 3 and the outer space 4. The level gauge 13 and the rain gauge 14 are electrically connected to the control box 12. The level gauge 13 measures the liquid level in the inner space 3 and the outer space 4 respectively. The electrically controlled flow regulating gate 10 adjusts the opening degree according to the internal measurement data fed back by the level gauge 13.
