Description

Technical Field

[0001] The utility model relates to the technical field of municipal drainage, in particular to a flexible regulating weir with sectional control. Background Technique

[0002] A regulating weir is an important facility for regulating water level and controlling water flow in water conservancy projects. Existing regulating weirs, such as the regulating weir gate disclosed in the utility model patent with the publication number CN202247802U and a large-width single-hoisting-point water level regulating weir gate structure disclosed in the utility model patent with the publication number CN220414156U, can intercept water flow and regulate water flow rate.

[0003] However, it is found in the use process that the existing regulating weir is not convenient to be applied in pipelines, and the installation is time-consuming and laborious, occupying more space. Moreover, it is not convenient to carry out interception at different heights, resulting in poor practicability. Therefore, there is an urgent need for a flexible regulating weir with sectional control to improve the above problems. Summary of the Utility Model

[0004] To solve the above technical problems, the utility model provides a flexible regulating weir with sectional control, which installs a fastening mechanism in a pipeline, discharges gas into a blocking mechanism through an air delivery mechanism, causes the blocking mechanism to expand, intercepts the water flow in the pipeline, and thus improves the practicability of the device.

[0005] The flexible regulating weir with sectional control of the utility model includes an air delivery mechanism; it also includes a fastening mechanism and a blocking mechanism, and both the air delivery mechanism and the blocking mechanism are installed on the fastening mechanism;

[0006] The fastening mechanism limits the blocking mechanism, the air delivery mechanism provides a gas source for the blocking mechanism, and the blocking mechanism intercepts the water flow;

[0007] Install the fastening mechanism in the pipeline, discharge gas into the blocking mechanism through the air delivery mechanism, cause the blocking mechanism to expand, intercept the water flow in the pipeline, and thus improve the practicability of the device.

[0008] Preferably, the fastening mechanism includes an arc-shaped support plate and multiple groups of hooks. Multiple inverted L-shaped limiting grooves are arranged at the bottom of the arc-shaped support plate, and multiple groups of hooks are all installed on the inner wall of the pipeline; put the arc-shaped support plate into the pipeline, make multiple groups of hooks respectively extend into multiple inverted L-shaped limiting grooves of the arc-shaped support plate, and then pull the arc-shaped support plate to the right to make multiple groups of hooks clamp the arc-shaped support plate. After that, the water flow flows from left to right in the pipeline, and under the impact of the water flow, the fastening effect of multiple groups of hooks on the arc-shaped support plate is further improved, thereby improving the practicability of the device.

[0009] Preferably, the gas transmission mechanism includes an exhaust pipe, multiple groups of first electric control valves, and a second electric control valve. The exhaust pipe is installed in the arc-shaped support plate. Multiple groups of first electric control valves and the second electric control valve are all installed on the exhaust pipe. Moreover, multiple groups of first electric control valves communicate with the inside of the blocking mechanism. The second electric control valve is installed at one end of the exhaust pipe. Connect the second electric control valve to the gas source. By opening the second electric control valve, gas enters the exhaust pipe. Then, by opening the first electric control valves, the gas is discharged into the blocking mechanism until the blocking mechanism expands to block the water flow in the pipeline, thereby improving the practicability of the device.

[0010] Preferably, the blocking mechanism includes multiple groups of water-blocking air bags and multiple groups of limiting mechanisms. Multiple groups of water-blocking air bags are all installed on the arc-shaped support plate. And the volume of the middle water-blocking air bag after inflation is larger than that of the left water-blocking air bag and smaller than that of the right water-blocking air bag. Multiple groups of blocking mechanisms are all installed on the central axis of the pipeline. The bottoms of multiple groups of blocking mechanisms are respectively installed on the tops of multiple groups of water-blocking air bags. Multiple groups of the first electric control valves communicate with the inside of multiple groups of water-blocking air bags respectively. By discharging the gas in the exhaust pipe into the water-blocking air bags through the first electric control valves, the water-blocking air bags expand to block the water flow in the pipeline. After use, the air in the water-blocking air bags is discharged through the first electric control valves. At the same time, the water-blocking air bags are squeezed downward through the limiting mechanisms, so that the water-blocking air bags are closely attached to the arc-shaped support plate, reducing the influence of the water-blocking air bags on the pipeline drainage, thereby improving the practicability of the device.

[0011] Preferably, the limiting mechanism includes an arc-shaped rubber plate. Both ends of the arc-shaped rubber plate are installed on the central axis of the pipeline. The bottom end of the arc-shaped rubber plate is connected to the top of the water-blocking air bag. And when the water-blocking air bag expands to intercept the water flow, the supporting effect of the water-blocking air bag is enhanced through the arc-shaped rubber plate. When the air in the water-blocking air bag is discharged, the water-blocking air bag is squeezed downward through the arc-shaped rubber plate, which is convenient for quickly discharging the gas in the water-blocking air bag. And through the extrusion of the arc-shaped rubber plate, the water-blocking air bag is closely attached to the arc-shaped support plate, reducing the influence of the water-blocking air bag on the pipeline drainage, thereby improving the utility model of the device.

[0012] Preferably, elastic protrusions are provided in the inverted L-shaped limiting groove of the arc-shaped support plate, and grooves are provided at the top ends of the hooks. After inserting the hooks into the inverted L-shaped grooves, the elastic protrusions enter the grooves of the hooks. And when the elastic protrusions enter the grooves of the hooks, the bottom ends of the elastic protrusions hit the bottom of the grooves of the hooks, making a sound to remind the staff that the arc-shaped support plate is installed in place, thereby improving the practicability of the device.

[0013] Preferably, both the left end and the right end of the arc-shaped support plate are inclined surfaces, which is convenient for the water flow in the pipeline to pass through, thereby improving the practicability of the device.

[0014] The beneficial effects of the present utility model compared with the prior art are as follows: The fastening mechanism is installed in the pipeline, and gas is discharged into the blocking mechanism through the gas transmission mechanism, causing the blocking mechanism to expand and intercept the water flow in the pipeline, thereby improving the practicability of the device.
