A non-power-limited flow-limiting intelligent interception well capable of floating slag

Abstract

The invention relates to an unpowered flow limiting type intelligent catch basin with a floating residue blocking function. The unpowered flow limiting type intelligent catch basin comprises a basin body. A sewage inflow pipe, an interception sewage pipe and an overflow water outflow pipe are communicated with the side wall of the basin body. A flow limiter is arranged in front of the interception sewage pipe and comprises an orifice, a box chamber, a floating ball and a wedge disc, wherein the floating ball and the wedge disc are arranged in the box chamber. The orifice is communicated with the interception sewage pipe, a linkage mechanism is connected between the floating ball and the wedge disc, and the floating ball ascends or descends to drive the wedge disc to descend or ascend. The overflow pollution problem generated to drained water is reduced when the flow quantity of a pipeline is large. The flow quantity can be precisely controlled, and the interception ratio can be guaranteed. Floating matter can be effectively intercepted, and the flow quantity of the overflow water outflow pipe can be monitored in real time. Remote intelligent control can be achieved, and the catch basin can be installed in a limited environment. A controller is arranged in the box chamber, and the risk of flow limiting failure caused by the fact that the liquid level of external sewage exceeds the maximum motion height of the floating ball is avoided. The catch basin can be suitable for smaller basin bodies, and is wide in application range.

Description

technical field [0001] The invention relates to the technical field of interception wells, in particular to a non-powered flow-limiting intelligent interception well capable of floating and retaining slag. Background technique [0002] For the combined drainage pipe network or the separate rainwater pipe network, because the mixed sewage or initial rainwater carries a large amount of particulate pollutants from sources such as urban surfaces, roofs, domestic sewage, and pipeline sediments, it is directly discharged without any interception treatment Entering the receiving water body of the city will cause pollution to the receiving water body. Therefore, it is necessary to intercept the combined pipe network or the separate rainwater pipe network, and set a certain interception multiple so that the intercepted sewage or initial rainwater is discharged into the terminal sewage treatment plant, and the water exceeding the interception capacity is discharged into the surface wa...

Problems solved by technology

The traditional interception wells have the following defects: (1) The flow restriction in the interception well is realized by simple rams or limited pipe diameters, which cannot achieve accurate flow restriction and ensure the design interception multiple; (2) With the comprehensive river channel management With the improvement of requirements, the pollutants in the overflow water must pass through certain interception devices before they can be discharged into the surface water body; (3) The interception well does not carry out real-time measurement of the overflow flow, which cannot provide information for the design, operation and management of the interception well and pipeline. Direct basis; (4) Simple and extensive, low management level
