Description
Technical Field
The utility model relates to an intercepting well, in particular to a floating regulation weir plate intercepting well.
Background
At present, a combined sewage drainage system is still adopted in some old urban areas in China for historical reasons, and domestic sewage, industrial wastewater and rainwater are mixed in a pipe canal and directly drained into a water body nearby. From the aspect of water environment, the main reason for water pollution is that. Because the intercepting type combined flow drainage system has less investment and is relatively easy to reform, the intercepting type combined flow drainage system is generally adopted in China to replace and reform the existing combined flow drainage system in the old city. Catch basins are used in combined rain and sewage systems for the purpose of separating rain and sewage. In dry seasons, because only sewage is in the pipe, the intercepting well can intercept the sewage and flow the sewage into the sewage pipe, in rainy seasons, part of rainwater and the sewage are intercepted and flow into the sewage pipe, and the rest of rainwater overflows through the weir in the well and continues to flow downstream.
The commonly used intercepting well forms include a groove type, a weir type and a groove and weir combined type. The weir type intercepting well is widely applied to intercepting type confluence system transformation at home and abroad, an overflow weir is arranged in the intercepting well, dry-run sewage is intercepted in sunny days, mixed sewage is intercepted in rainfall, and the mixed sewage exceeding the intercepting capability is discharged into a water body over the overflow weir. The groove type intercepting well is characterized in that an intercepting groove with the same width as the diameter of the intercepting pipe is arranged in the intercepting well, the groove bottom is lower than the inner bottom of the intercepted pipe, and the groove depth is generally smaller than the pipe diameter of the intercepting pipe. A lower overflow weir is arranged in the intercepting well, and meanwhile, an intercepting groove is arranged in front of the overflow weir and is the intercepting well combined with the groove weir.
An overflow weir is generally arranged in a common intercepting well at present, and when the overflow weir is also used for blocking the backflow of river water, the elevation of the top of the overflow weir is not lower than the water level of a river channel, so that the overflow weir is generally arranged higher. When rainstorm occurs, runoff in the cut-off pipe needs to overflow from the top of the overflow weir, a weir water head H is generated, so that the upstream pipeline starting calculation water level is changed from the river channel water level to the water level before the weir, the hydraulic gradient of the upstream pipeline is reduced, the drainage capacity of the upstream pipeline is reduced, and the problem of waterlogging is easily increased. But if the weir is simply cancelled, the risk of river water flowing backwards is greatly increased.
Therefore, aiming at the defects of the existing intercepting well, it is necessary to design the intercepting well with the weir height automatically adjusted according to the water quantity, no manpower consumption, energy conservation, environmental protection and stable operation.
Disclosure of Invention
The utility model solves the problem that the drainage capacity of the existing catch basin is reduced due to the weir water head generated when rain and sewage are combined in rainy days, can reduce the risk of flowing back of river water to a certain extent, is simple to maintain, is energy-saving and environment-friendly, and provides the floating regulation weir plate catch basin.
The utility model is realized by adopting the following technical scheme: a floating regulation weir plate intercepting well comprises a well body, an intercepted pipe, an intercepting pipe, an overflow pipe and a fixed weir plate, wherein the intercepted pipe, the intercepting pipe and the overflow pipe are communicated with the well body; a fixed shaft is horizontally arranged on the inner wall of the well body at a position higher than the fixed weir plate, the fixed shaft is connected with an adjustable weir plate capable of rotating around the fixed shaft, the lower part of the adjustable weir plate is lower than the top of the fixed weir, and the lower part of the adjustable weir plate is positioned on one side of the fixed weir plate facing the overflow pipe; one side of the lower part of the adjustable weir plate, which faces the overflow pipe, is connected with a floating ball.
When rain sewage confluence water yield is big, overflow pipe one side through fixed weir plate overflow, along with the water yield increases, the liquid level rises, and the floater drives adjustable weir plate and rises to overflow pipe one side, further opens the space of overflow, can reduce the weir head, has increased the drainage ability of vatch basin. When the river flows backward, the adjustable weir plate is reversely extruded by the river, the lower side of the weir plate is pressed to fix the weir plate, and the weir plate is compacted more tightly along with the increase of the backward flowing water quantity, so that the backward flowing river is remained on one side of the overflow pipe, and a certain effect of preventing the river from flowing backward is achieved. The adjustable weir plate intercepting well combines the respective advantages of a weir type intercepting well and a groove type intercepting well to the maximum extent, and the defects of the weir plate intercepting well are avoided.
Compared with the prior main catch basin, the weir height of the utility model is lower, the adjusting weir is adjusted by the buoyancy of water, and part of water flows to one side of the overflow pipe through the hole, thereby reducing the weir water head and improving the flood discharge capacity; 2. compared with a groove type intercepting well, the backward flowing river can extrude the adjustable weir plate to close the adjustable weir plate and the fixed weir plate, and the river is blocked at one side of the overflow pipe, so that the risk of backward flowing of the river is reduced; 3. compared with a manual gate, the gate is more convenient, and the labor input is greatly reduced; 4. compared with a mechanical gate, the novel gate valve does not need to be provided with a power supply, is more economical and environment-friendly, has less equipment faults and reduces the cost.

The height of the fixed weir plate 4 is smaller, and the adjustable weir plate 6 can move to the left side through the pressure of water when the river flows backward and is closed with the fixed weir plate 4.
Example 2
The fixed shaft 5 is movably sleeved with a sleeve 9, and the adjustable weir plate 6 is connected below the sleeve 9. The floating ball 7 moves up and down by utilizing the liquid level to drive the upper sleeve 9 of the adjustable weir plate 6 to rotate around the fixed shaft 5.

The connecting pipe 8 is connected with the slightly upper part of the bottom of the adjustable weir plate 6, so that the floating ball 7 can float to the right side only, and the adjustable weir plate 6 is driven to open to the right (as shown in fig. 3 and 4).
Example 4
The cut-off pipe 1 and the overflow pipe 3 are respectively connected to the opposite side walls of the well body 10, and the cut-off pipe 2 is connected to the well body 10 between the fixed weir plate 4 and the cut-off pipe 1; the direction of the fixed shaft 5 is vertical to the axial direction of the intercepted pipe 1 and the overflow pipe 3; the fixed shaft 5 is disposed near the top of the well body 10.
