Technical Field
[0001] The utility model relates to the technical field of municipal drainage, and in particular to a bottom-opening weir type diversion well structure. Background Art
[0002] The lower weir-type diversion well is a commonly used municipal drainage diversion well structure. On sunny days, the gate 41 of the sewage interception port 4 is in an open state, and the gate plate 5 is in an upward semi-closed state. The domestic sewage from the water inlet 2 is completely intercepted to the sewage interception port 4 and transported to the sewage treatment plant through a pipeline. At the beginning of rainfall, the water level in the well body 1 is lower than the urban flood warning water level. The initial rainwater and sewage enter the sewage interception port 4, and the dirtier rainwater enters the sewage interception main pipe. In the middle and late stages of rainfall, the gate 41 is closed, and the cleaner rainwater overflows the gate plate 5 and is discharged from the drainage port 3 to the natural water body. When the city discharges flood water, the gate plate 5 drops and opens completely, and the gate 41, the flood water is discharged from the drainage port 3 to the natural water body.
[0003] In this process, the gate plate 5 needs to reciprocate and expand in the gate plate groove 11, and when rainwater and sewage flow through the gate plate 5, fine silt will enter the gate plate groove 11 from the gap between the gate plate groove 11 and the gate plate 5. Over time, a large amount of silt will accumulate in the gate plate groove 11, thereby affecting the use of the gate plate 5. At present, the silt removal in the gate plate groove 11 can only be carried out after the gate plate 5 is removed, and the engineering workload is large. Utility Model Content

DETAILED DESCRIPTION
[0020] The embodiments of the present invention will be further described below in conjunction with the accompanying drawings.
[0021] See also Figure 1-2 A bottom-opening weir-type diversion well structure comprises a well body 1, a water inlet 2 is arranged on one side of the well body 1, a drain outlet 3 is arranged on the other side, a gate plate groove 11 is arranged at the bottom of the well body 1, a gate plate 5 is slidably installed in the gate plate groove 11, a sewage interception port 4 is arranged on one side between the water inlet 2 and the gate plate 5 in the well body 1, a gate 41 is installed at the sewage interception port 4, an empty cavity 13 is arranged at the bottom of the gate plate groove 11, a sewage well 14 is arranged on the outer wall of the well body 1 at the gate plate groove 11, the sewage well 14 is connected with the empty cavity 13, and a sewage discharge device 6 is installed in the sewage well 14. Through the above structure, silt will accumulate in the empty cavity 13. Since the sewage well 14 is connected to the empty cavity 13, when the water in the sewage well 14 is discharged through the sewage discharge device 6, the silt in the empty cavity 13 will enter the sewage well 14 driven by the water flow and be discharged through the sewage discharge device 6, thereby eliminating the need to dismantle the gate plate 5 before dredging.
[0022] See also Figure 1 A grille 12 is installed at the bottom of the gate slot 11, and the vacant cavity 13 is located at the lower side of the grille 12. The grille 12 can support the gate 5 when the gate 5 is fully retracted into the gate slot 11, thereby reducing the pressure of the supporting gate 5 on the hydraulic cylinders on both sides.
[0023] In the first solution, the sewage discharge device 6 includes a sewage pump 61, which is installed at the bottom of the sewage well 14, and one end of the sewage pipe 62 is connected to the water outlet of the sewage pump 61, and the other end extends to between the water inlet 2 and the gate plate 5 in the well body 1. The water in the sewage well 14 is discharged into the well body 1 through the sewage pump 61.
[0024] For further information, see Figure 2, because the fluidity of the silt in the vacant cavity 13 is reduced after a lot of sediment is accumulated, the silt in the vacant cavity 13 cannot be completely taken out by drainage alone, therefore, the other end of the sewage pipe 62 extends to the outside of the well body 1 and is located on the side opposite to the sewage well 14, and is connected to the vacant cavity 13, and a branch pipe 63 is provided on the sewage pipe 62, and the branch pipe 63 is located between the water inlet 2 and the gate plate 5 in the well body 1, and valves 64 are respectively installed on the branch pipe 63 and on the downstream side of the branch pipe 63 on the sewage pipe 62. Through the above structure, the vacant cavity 13 can be flushed in a cycle first, and the silt can be dispersed and then discharged, which has a better effect.
[0025] See also Figure 1 A floating baffle 7 is installed in the well body 1 between the interception port 4 and the gate plate 5 and parallel to the gate plate 5. The two side walls of the well body 1 are respectively provided with longitudinal slide grooves 17. The two ends of the floating baffle 7 are freely slidably installed in the slide grooves 17 on both sides. The floating baffle 7 is provided to reduce the drainage speed of the water inlet 2, facilitate sediment deposition, reduce the possibility of entering the gate plate groove 11, and can also intercept floating objects discharged from the water inlet 2. Specifically, the floating baffle 7 is made of stainless steel plate to form a hollow box structure.
[0026] The slide groove 17 can be a groove opened on the inner wall of the well body 1, or can be two angle steels installed on the inner wall of the well body 1, and the two angle steels are installed at an interval.
[0027] In order to prevent sediment from entering the gate groove 11, the upper end of the gate groove 11 extends a distance from the bottom wall of the well body 1, so that a first sewage collection trough 15 is formed between the water inlet 2 and the gate groove 11, and a second sewage collection trough 16 is formed between the gate groove 11 and the drain port 3. The first sewage collection trough 15 and the second sewage collection trough 16 can deposit sediment, thereby reducing the sediment from entering the gate groove 11.
[0028] The working principle of this utility model:
[0029] See also Figure 2, the sewage pump 61 is installed at the bottom of the sewage well 14, one end of the sewage pipe 62 is connected to the water outlet of the sewage pump 61, and the other end extends to the outside of the well body 1 and is located on the side opposite to the sewage well 14, and is connected to the empty cavity 13. The sewage pipe 62 is provided with a branch pipe 63, and the branch pipe 63 is located between the water inlet 2 in the well body 1 and the gate plate 5. Valves 64 are respectively installed on the branch pipe 63 and on the sewage pipe 62 at the downstream side of the branch pipe 63. When cleaning the sediment, the valve 64 on the branch pipe 63 is closed first, the valve 64 on the sewage pipe 62 is opened, and the sewage pump 61 is turned on. The water in the sewage well 14 enters the other end of the empty cavity 13 through the sewage pipe 62, and the empty cavity 13 is drained at one end and water is inletted at the other end, thereby circulating and flushing the empty cavity 13 to disperse the sediment. Then, the valve 64 on the branch pipe 63 is opened, and the valve 64 on the sewage pipe 62 is closed, so that the turbid liquid in the sewage well 14 is discharged into the well body 1 and discharged from the sewage interception port 4.
