Description

Technical Field

[0001] This utility model relates to the field of municipal drainage technology, and in particular to an adjustable outlet weir gate for intercepting sewage wells. Background Technology

[0002] Interception wells are an important facility in urban drainage systems, primarily used to control and manage the flow of sewage, preventing untreated wastewater from being directly discharged into natural water bodies, thereby protecting the environment from pollution. They are typically located at the intersection of rainwater and sewage pipes or at the outlet of specific pollution sources. Interception wells effectively separate sewage and direct it to sewage treatment plants for purification, ensuring that only treated and compliant water is discharged into the environment.

[0003] Traditional intercepting sewers often employ fixed weirs or simple gate structures, which suffer from problems such as inflexible water level regulation, susceptibility to clogging, and insufficient backflow prevention. For example, conventional weirs have a fixed height, making it difficult to dynamically control the drainage flow according to actual needs, easily leading to sewage retention or excessive discharge. Simultaneously, the lack of an automatic shut-off mechanism when external water levels fluctuate results in frequent backflow, affecting the safe operation of the pipe network. Furthermore, inadequate water flow guidance design within the well allows sewage to easily accumulate at the bottom, exacerbating the risk of clogging. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an adjustable effluent weir gate for intercepting sewage wells.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An adjustable effluent weir gate for intercepting sewage wells includes a well body, a fixed frame fixedly connected to the inner bottom of the well body, a lifting block slidably inserted inside the fixed frame, a driving mechanism for moving the lifting block provided at the inner bottom of the fixed frame, a drain pipe communicating with the inside of the well body fixedly connected to the right side of the well body, an installation frame fixedly connected to the other end of the drain pipe, a through groove opened on the side of the installation frame near the drain pipe, and a closing mechanism provided inside the installation frame.

[0007] As a further improvement of this utility model, the driving mechanism includes a double-headed motor fixedly connected to the bottom of the fixed frame. Both output shafts of the double-headed motor are fixedly connected to worm gears. The other ends of the two worm gears are rotatably connected to the inner wall of the fixed frame. The lower end of the lifting block has two threaded grooves. Threaded rods are threaded into the two threaded grooves. The lower ends of the two threaded rods are rotatably connected to the bottom of the fixed frame. Worm wheels are fixedly sleeved on the two threaded rods. The two worm wheels mesh with the two worm gears respectively.

[0008] As a further improvement of this utility model, the closing mechanism includes fixed blocks fixedly connected to the inner two side walls of the mounting frame. Each of the two fixed blocks has a sliding groove on one side that is close to each other. The same sliding block is slidably arranged in the two sliding grooves. A lifting plate is fixedly connected to the lower end of the sliding block, and a floating plate is fixedly connected to one side of the lifting plate.

[0009] As a further improvement of this utility model, a water inlet pipe is fixedly connected to the left side of the well body, and the water inlet pipe is connected to the inside of the well body.

[0010] As a further improvement of this utility model, a sewage pipe is provided below the water inlet pipe and is fixedly connected to the well body, and the sewage pipe is connected to the inside of the well body.

[0011] As a further improvement of this utility model, an inclined block is fixedly connected to the inner bottom of the well body, and the inclined block is set on the side of the fixed frame near the sewage pipe.

[0012] As a further improvement of this utility model, guide blocks that are fixedly connected to the inner wall of the well body are provided on both sides of the inclined block.

[0013] As a further improvement of this utility model, the inner diameter of the drain pipe is the same as the inner diameter of the through groove.

[0014] As a further improvement of this utility model, the size of the lifting block matches the size of the internal cross-section of the fixed frame.

[0015] As a further improvement of this utility model, the inner diameters of the water inlet pipe, sewage pipe and drainage pipe are the same.

[0016] The beneficial effects of this utility model are:

[0017] By setting up a drive mechanism using a dual-head motor to drive a worm gear and worm wheel system, the lifting block moves up and down, achieving dynamic adjustment of the outlet weir height. This allows for precise control of the drainage flow rate according to actual needs, significantly improving the flexibility and operational efficiency of water flow management. Simultaneously, the addition of inclined blocks and guide blocks at the bottom of the well body optimizes the sewage flow direction, ensuring smooth flow of sewage into the sewage pipe, avoiding stagnation, and effectively reducing the risk of blockage.

[0018] By setting up a sealing mechanism, an installation frame is installed at the end of the drainage pipe, with a float plate and a lifting plate inside. When the external water level rises, the float plate rises with the water level, driving the lifting plate to automatically close the channel and prevent backflow. When the water level drops, the channel reopens to ensure smooth drainage. This design not only enhances the system's backflow prevention capability but also further ensures the safety and reliability of the pipeline network operation.

[0019] This invention significantly improves the flexibility of water flow management, reduces the risk of siltation, enhances the ability to prevent backflow, and ensures the safety and reliability of pipeline operation. Attached Figure Description

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Figures 1-5An adjustable effluent weir gate for intercepting sewage wells includes a well body 1. An inlet pipe 2 is fixedly connected to the left side of the well body 1, communicating with the interior of the well body 1 to introduce external water flow into the well body 1. Below the inlet pipe 2, a sewage pipe 3 is fixedly connected to the well body 1, communicating with the interior of the well body 1 to discharge sewage from the well body 1. A fixed frame 9 is fixedly connected to the inner bottom of the well body 1. A lifting block 11 is slidably inserted into the interior of the fixed frame 9. The size of the lifting block 11 matches the internal cross-sectional size of the fixed frame 9 to ensure smooth sliding within the fixed frame 9. A driving mechanism is provided at the inner bottom of the fixed frame 9 to drive the lifting block 11. The driving mechanism includes components fixedly connected to the inner bottom of the fixed frame 9. The dual-head motor 10 has two output shafts fixedly connected to worm gears 13. The other ends of the two worm gears 13 are rotatably connected to the inner wall of the fixed frame 9 to achieve power transmission. The lower end of the lifting block 11 has two threaded grooves 12, and threaded rods 15 are threadedly connected to the two threaded grooves 12. The lower ends of the two threaded rods 15 are rotatably connected to the bottom of the fixed frame 9. Worm wheels 14 are fixedly sleeved on the two threaded rods 15. The two worm wheels 14 mesh with the two worm gears 13 respectively. Through the meshing transmission between the two worm wheels 14 and the two worm gears 13, the two threaded rods 15 are driven to rotate, thereby driving the lifting block 11 to move up and down, so as to control the water flow and the size of the outflow.

[0028] A drain pipe 4, communicating with the interior of the well body 1, is fixedly connected to the right side of the well body 1. The inner diameters of the inlet pipe 2, the sewage pipe 3, and the drain pipe 4 are the same to ensure smooth water flow. A mounting frame 5 is fixedly connected to the other end of the drain pipe 4. A through groove 18, with the same inner diameter as the drain pipe 4, is opened on the side of the mounting frame 5 near the drain pipe 4 to guide water from the drain pipe 4 into the mounting frame 5 and discharge it. A closing mechanism is provided inside the mounting frame 5, which includes fixing blocks 16 fixedly connected to the two inner side walls of the mounting frame 5. The two fixing blocks 16 are mutually... A sliding groove 17 is provided on both sides of the sliding frame 5. The same sliding block 19 is slidably installed in the two sliding grooves 17. A lifting plate 6 is fixedly connected to the lower end of the sliding block 19. A float plate 20 is fixedly connected to one side of the lifting plate 6. When the water level outside the mounting frame 5 rises, the float plate 20 rises with the water level, driving the lifting plate 6 and the sliding block 19 to rise along the sliding groove 17, thereby closing the through groove 18 and preventing backflow of external water. When the water level outside the mounting frame 5 drops, the float plate 20 drops with the water level, and the through groove 18 reopens, realizing automatic control of water flow.

[0029] An inclined block 7 is fixedly connected to the bottom of the well body 1. The inclined block 7 is set on the side of the fixed frame 9 near the sewage pipe 3 to guide the sewage to flow to the sewage pipe 3 and avoid sewage stagnation. Both sides of the inclined block 7 are provided with guide blocks 8 fixedly connected to the inner wall of the well body 1. The guide blocks 8 are used to further guide the direction of water flow and ensure that the sewage flows smoothly into the sewage pipe 3.

[0030] When using this utility model, first connect the external power supply, then start the dual-head motor 10 to drive the two worm gears 13 and two worm wheels 14 to rotate, and respectively drive the two threaded rods 15 to rotate, so that the lifting block 11 moves up and down along the inside of the fixed frame 9, and adjusts the height of the outlet weir gate to control the drainage flow. In daily operation, keep the inside of the well body 1 clean, regularly observe whether the sewage pipe 3 and the drainage pipe 4 are unobstructed, and check whether the float 20 rises and falls flexibly with the water level. When the external water level rises, the float 20 drives the lifting plate 6 and the sliding block 19 to automatically close the through channel 18 to prevent backflow. When the water level drops, the through channel 18 reopens.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
