Abstract

The invention relates to a water tank water inlet multi-water-pipe energy dissipation and flow stabilization system and an operation method; the system includes a water tank, and a rectangular water tank that is communicated with the water tank; a partition plate is arranged in the rectangular water tank, and is in a L-shape; the vertical part of the partition plate is vertical to the bottom surface of the rectangular water tank; the horizontal part of the partition plate is parallel to the bottom surface of the rectangular water tank; a distance is reserved between the horizontal part of thepartition plate and the bottom face of the rectangular water tank, the partition plate divides an inner cavity of the rectangular water tank into two parts different in size, a water groove water inlet is formed in the side wall of the rectangular water tank, and a water supply pipeline is arranged above a second cavity of the rectangular water tank and connected with a water outlet pipe which extends into the second cavity. An energy dissipation and flow stabilization body is installed in the first cavity, and the energy dissipation and flow stabilization body comprises a first multi-water-pipe flow stabilizer which is erected in the first cavity; the device can effectively reduce the energy of water flow at a high position before entering the water tank, and the effective length of the experimental section of the working water tank is increased.

[0002] At present, due to the limited experimental sites in colleges and universities, there is basically no condition to build experimental water tanks with long straight-line distances, especially for water flow research experimental water tanks for teaching. The unstable flow state of the water flow makes the effective working distance of the experimental water tank very limited. In order to improve the use effect of the water tank, necessary flow stabilization treatment must be taken at the water inlet, and the severe water turbulence caused by the difference in water head and the excessive instantaneous flow rate must be taken. motion, that is, it is necessary to take effective measures to eliminate or reduce the turbulent kinetic energy not required for the experiment

[0003] At present, the treatment method for the unstable water flow of the water inlet tank is usually to use geotechnical mats to dissipate energy, and then flow into the working water tank after standing still in the rectangular water tank, resulting in too long section of unstable water flow at the water inlet; In the case of water supply and the working range of the experimental tank is only a dozen meters, if the energy dissipation facilities at the inlet and outlet cannot play a significant role in stabilizing the flow, it will reduce the effective length of the experimental tank, greatly reducing the experimental efficiency and stability
