Detailed ways

The utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments to facilitate a clear understanding of the utility model, but they do not limit the utility model.

As shown in Figures 1-4, the utility model includes a swirl constant flow body 7, and the swirl constant flow body 7 includes a swirl part 7.1 and a diversion part 7.2 connected to each other; the swirl part 7.1 is two circular baffles A closed cylindrical structure surrounded by a surface 7.11 and a cylinder 7.12; the diversion part 7.2 is tubular, and the diversion part 7.2 is connected to the bottom of the cylinder 7.12 of the swirl part 7.1 and is tangent to the swirl part 7.1; the diversion part 7.2 There is a water inlet 7.21 at the bottom, and one of the circular retaining surfaces 7.11 of the swirl part 7.1 has a water outlet 7.13 along the center; one of the circular retaining surfaces 7.11 of the swirl part 7.1 is provided with a fixing device, and a lifting device is provided on the fixing device .

5-9, the swirl constant flow body 7 is fixed at the outlet pipe 3 in the inspection well 9 through a fixing device, and the water outlet 7.13 communicates with the outlet pipe 3. The fixing device includes an operation panel 5 and a mounting panel 4. The operation panel 5 is fixed on one of the circular retaining surfaces 7.11 of the swirl part 7.1. The operation panel 5 includes an operation panel body 5.1, and the center of the operation panel body 5.1 has a first through hole 5.2 , the left and right sides of the operating panel body 5.1 are wedge-shaped structures 5.3; the mounting plate 4 is fixed on the inner wall of the inspection well 9, the mounting plate 4 includes the mounting plate body 4.1, the center of the mounting plate body 4.1 has a second through hole 4.2, and the mounting plate body 4.1 The left and right sides are provided with dovetail groove 4.3 for wedge-shaped structure 5.3 insertion, as shown in Figure 6 and Figure 7, the upper part of the notch of the dovetail groove 4.3 is wider and the lower part is narrow, and a sealing ring 8 is provided between the mounting plate 4 and the operating plate 5 to seal .

The hoisting device is an operating rod 6 fixedly connected to the top of the operating board 5 by a fixing ring 5.4 at the top of the operating board 5 , and the upper end of the operating rod 6 stretches out of the inspection well 9 .

In the utility model, the water inlet 7.21 of the swirl constant flow body 7 is lower than the water outlet 7.13, which can intercept oil stains and floating objects, and prevent pollution and blockage of pipelines.

The utility model is suitable for setting the outlet pipe 3 higher than the bottom of the sump 2 of the inspection well 9, that is, there is a distance h between the outlet pipe 3 and the bottom of the sump 2, so that when the swirl constant flow body 7 is installed, the swirl constant flow The water outlet 7.13 of the body 7 is aligned with the outlet pipe 3, leaving an installation space for the lower part of the swirl constant flow body 7 in the sump 2. During installation, the swirl constant flow body 7 can be operated on the ground through the operating lever 6. The plate 5 is inserted into the dovetail groove 4 . 3 of the mounting plate 4 of the manhole 9 .

The working principle of the utility model: the swirling constant flow device of the utility model relies on the eddy current effect produced naturally to control the flow without moving parts. In the absence of flow, the swirl constant flow device can act as a water trap to prevent odors from escaping downstream pipes. Because the inlet pipeline 1 of the inspection well 9 is lower than the outlet pipeline 3, the cyclone constant flow device can intercept the oil pollution and floating objects carried by the rainwater runoff or flood to enter the downstream pipeline. When rainfall of low to moderate intensity occurs, the water flows directly through the cyclone constant flow device, and the flow through the cyclone constant flow device increases, and the flow rate also increases. When heavy rainfall or flood occurs, the flow rate through the swirl constant flow device will increase to make the water flow generate a vortex in the specially designed arc-shaped swirl constant flow body 7, and this vortex will make the air in the center of the orifice of the outlet Concentrating to form a cavity, this cavity actually reduces the effective cross-sectional area of the orifice flow channel, which is equivalent to reducing the diameter of the orifice, thereby reducing the outlet flow. After the rainfall stops, the water level drops and the flow velocity decreases until the vortex effect disappears, and the swirl constant flow device returns to normal. Therefore, when the flow rate is too large, the swirl constant flow device can immediately and automatically limit the flow into the downstream pipeline, allowing the rainwater to be temporarily stored in the groundwater well or surface pool, so as to ensure that the rainwater can be slowly discharged into the drainage system, ensuring that the drainage pipes, sewage The processing plant etc. are working normally.
