Description

Technical Field

[0001] This utility model relates to the field of interception well technology, and more specifically, to an integrated rotating weir gate interception well. Background Technology

[0002] Interception wells, as the core hubs of urban drainage systems for controlling pollution sources and intercepting wastewater, are crucial facilities for solving the problem of combined sewer overflows and protecting water quality. In towns where combined sewer systems still account for a high proportion, they bear the dual responsibility of completely intercepting domestic sewage during the dry season and precisely separating initially polluted rainwater from clean rainwater in the later stages of the rainy season. During the dry season, sewage is diverted to wastewater treatment plants through interception channels to prevent direct discharge of pollution; during the rainy season, weirs or sluice gates are used to regulate the flow, intercepting initial rainwater carrying surface pollutants while ensuring rapid drainage of later rainwater into rivers to alleviate flooding.

[0003] Traditional weir-type interception wells, trough-type interception wells, and trough-weir-type interception wells cannot control the interception flow. Some weir-type interception wells cannot adjust the weir height, which affects drainage during heavy rains and cannot prevent backflow of river water when the river level is high, resulting in poor sewage interception effect. Therefore, there is an urgent need to provide an integrated rotating weir gate interception well to solve the above problems. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides an integrated rotary weir gate interception well. Based on the water level provided by the level gauge, the hydraulic cylinder of the rotary weir gate is controlled to realize the opening and closing of the hydraulically rotating weir gate, thereby controlling the interception height of the weir gate. It can realize functions such as interception and water storage, control of drainage flow, timely flood discharge, and prevention of river backflow.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: The integrated rotating weir gate interceptor well includes: A submersible sewage pump is located at the bottom of the cylinder. The submersible sewage pump is connected to a check valve through a pressure pipeline. The upper end of the check valve is connected to a gate valve. The upper end of the gate valve is connected to a forced discharge pipe. A water inlet pipe and a rain drain pipe are respectively provided on both sides of the bottom of the cylinder. A basket grid is provided at one end of the water inlet pipe. Two baffles are provided, with the bottom and rear sides of the baffles connected to the bottom wall and inner wall of the cylinder, respectively. A hydraulically driven rotary weir gate is provided on the front side of the two baffles. The liquid level sensor assembly and service platform are located in the cylinder, the manhole cover and ventilation pipe are located on the top of the cylinder, and a control cabinet and rain gauge are also installed above the cylinder.

[0006] As a further improvement to this utility model, the submersible pump is installed at the bottom of the cylinder via a coupling base.

[0007] As a further improvement to this utility model, two submersible sewage pumps are provided, and the two submersible sewage pumps are respectively located on the sides of the two partitions, and the two gate valves are connected to the forced drainage pipe.

[0008] As a further improvement to this utility model, the forced drainage pipe, the water inlet pipe, and the rain drain pipe are respectively provided with a forced drainage pipe flexible joint, a water inlet pipe flexible joint, and a rain drain pipe flexible joint.

[0009] As a further improvement to this utility model, the hydraulic rotary weir gate is rotatably mounted on the rotary weir gate base at the bottom of the submersible sewage pump, and a hydraulic assembly is provided on the back side of the hydraulic rotary weir gate.

[0010] As a further improvement to this utility model, the inlet of the rain drain pipe is located between the two partitions.

[0011] As a further improvement to this utility model, a ladder is provided between one wellhead of the cylinder and the service platform.

[0012] As a further improvement to this utility model, the basket grid is located between two grid guide rails, and the basket grid can be removed from another well opening of the cylinder.

[0013] The beneficial technical effects of this utility model are: This utility model internally incorporates a submersible sewage pump and a hydraulically operated rotary weir. The control cabinet intelligently controls the hydraulic cylinder of the rotary weir to open and close based on the water level provided by the level gauge. On sunny days, sewage and initial rainwater are pumped to the sewage treatment plant via the submersible pump. During heavy rains, the hydraulically operated rotary weir opens, discharging the clearer rainwater into the river, thus achieving intelligent separation of rainwater and sewage in the intercepting well.

[0014] This utility model can both timely discharge floodwater and prevent backflow of river water; the overall equipment is buried at a shallow depth, making it suitable for areas where there are requirements for equipment burial depth; when the integrated rotating weir gate interception well experiences an emergency power outage, the system still has the ability to drain floodwater, and there is no risk of the cylinder being overfilled.

[0017] In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0018] Combination Figure 1 - Figure 2 The present invention provides the following embodiments: The integrated rotating weir gate interceptor well includes: A submersible sewage pump 1 is installed at the bottom of the cylinder 6 via a coupling base 2. The submersible sewage pump 1 is connected to a check valve 7 via a pressure pipe 5. The upper end of the check valve 7 is connected to a gate valve 8. The upper end of the gate valve 8 is connected to a forced discharge pipe 11. A water inlet pipe 13 and a rain drain pipe 16 are respectively provided on both sides of the bottom of the cylinder 6. A basket grid 9 is provided at one end of the water inlet pipe 13 extending to one end of the cylinder 6. Two baffles 25 are provided, with the bottom and rear side of the baffles 25 connected to the bottom wall and inner wall of the cylinder 6 respectively. A hydraulically driven rotary weir gate 15 is provided on the front side of the two baffles 25. The liquid level sensor assembly 4 and service platform 24 are located in the cylinder 6, the manhole cover 20 and ventilation pipe 21 are located on the top of the cylinder 6, and the control cabinet 22 and rain gauge 23 are also located on the top of the cylinder 6.

[0019] Wastewater enters the integrated intercepting well through inlet pipe 13. Inlet pipe 13 is connected to basket screen 9, which is used to intercept large floating objects and debris, reducing the impact of pump operation. Submersible sewage pump 1 is fixed to the bottom of the intercepting well cylinder 6 via coupling base 2. Submersible sewage pump 1 is connected to check valve 7 via pressure pipe 5. Gate valve 8 is connected to the upper end of check valve 7, and the upper end of gate valve 8 is connected to the outlet of forced discharge pipe 11. The height of baffle 25 is flush with the height of hydraulic rotary weir gate 15. Baffle 25 can be fixed to cylinder 6 with bolts. The interior of baffle 25 is made of 304 stainless steel, and the exterior is sealed with GRP material. The inlet of rainwater drain pipe 16 is located between the two baffles 25.

[0020] The liquid level sensor assembly 4 includes a protective tube and a liquid level sensor. The liquid level sensor is placed inside the protective tube. The liquid level sensor assembly 4 detects the liquid level in the intercepting well and the downstream river channel in real time. The rain gauge 23 and the control cabinet 22 are both installed above the cylinder 6. The rain gauge 23 is used to monitor rainfall. The control cabinet 22 receives signals from the liquid level sensor and the rain gauge 23, and at the same time controls the submersible sewage pump 1 and the hydraulic rotary weir gate 15.

[0021] Furthermore, two submersible sewage pumps 1 are provided, each located on the side of one of the two partitions 25. Both gate valves 8 are connected to the forced drainage pipe 11. Referring to the attached diagram, specifically, the partitions 25 serve a separating function. When the water level is low, each submersible sewage pump is in a relatively independent environment, with relatively stable water flow around it, and is not disturbed by adjacent submersible sewage pumps, allowing it to operate normally and ensuring its working efficiency. Furthermore, a pump guide rail 3 is also provided. The core function of the pump guide rail 3 is to guide the precise installation and stable operation of the submersible sewage pumps 1, and to facilitate the lifting or lowering of the submersible sewage pumps 1 during later maintenance, ensuring controllable vertical movement and positioning of the submersible sewage pumps 1 underwater.

[0022] Furthermore, the forced drainage pipe 11, the inlet pipe 13, and the rainwater drainage pipe 16 are equipped with a flexible joint 12 for the forced drainage pipe, a flexible joint 14 for the inlet pipe, and a flexible joint 17 for the rainwater drainage pipe, respectively. Specifically, in actual construction, there may be length errors in the pipeline or the flanges may not be precisely aligned. The variability of the flexible joint can reduce the installation accuracy requirements. During operation, the pipeline may displace due to temperature changes or external environmental influences. The flexible joint can offset this displacement through its own deformation, preventing pipeline cracking or leakage at the connection.

[0023] Furthermore, the hydraulic rotary weir 15 is rotatably mounted on the rotary weir foundation 26 at the bottom of the submersible pump 1, and a hydraulic assembly is provided on the back side of the hydraulic rotary weir 15. Specifically, the rotary weir foundation 26 is located at the bottom of the cylinder 6, and the interior of the rotary weir foundation 26 is made of stainless steel 304 to form a box frame, and the exterior is wrapped with GRP material, mainly to support the hydraulic rotary weir 15.

[0024] Furthermore, a ladder 18 is provided between one of the well openings of the cylinder 6 and the service platform 24. Access to the service platform 24 inside the cylinder 6 is facilitated via the ladder 18 from this well opening, allowing for convenient inspection and maintenance of the cylinder 6's interior. This well opening is also equipped with a safety grille 19.

[0025] Furthermore, the basket grid 9 is located between two grid guide rails 10, and the basket grid 9 can be removed from another opening of the cylinder 6. The grid guide rails 10 are used to limit the basket grid 9 and also facilitate the removal and maintenance of the basket grid 9.

[0026] When sewage and initial rainwater enter the integrated interception well through the inlet pipe 13, the hydraulic rotary weir 15 closes (i.e., the weir is in a vertical direction). The sewage is diverted by the baffle 25 and the hydraulic rotary weir 15 to the side of the submersible sewage pump 1. The submersible sewage pump 1 is turned on to pump the sewage to the sewage treatment plant. After a certain period of continuous rainfall, the water gradually becomes cleaner, and the residual sewage in the pipeline has been washed away by the initial rainwater. According to the signals from the level sensor component 4 and the rain gauge 23, the system enters the mid-to-late rainwater mode after the rainwater gradually becomes cleaner. At this time, the submersible sewage pump 1 stops working, and the hydraulic rotary weir 15 opens to allow the less polluted upper layer of water to overflow. When the rainfall reaches its peak, the hydraulic rotary weir 15 is fully opened (i.e., the weir is in a horizontal direction). The rainwater flows into the river through the drainage pipe 16, realizing the smooth and rapid discharge of the later rainwater, thereby achieving the effect of separating rainwater and sewage. At the same time, the level sensor component 4 can detect and transmit the level signal to prevent rainwater from the river from flowing back into the integrated interception well.

[0027] If the hydraulic rotary weir gate 15 fails to work properly, rainwater will overflow through the hydraulic rotary weir gate 15 to the flexible joint 14 of the inlet pipe and be discharged into the river. The system still has the ability to drain water and there is no risk of the cylinder being overfilled.

[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit 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.
