Composite hole-type water stabilizing grating device

Abstract

The invention provides a composite hole-type water stabilizing grating device, which comprises a water inlet chamber, wherein a water inlet pipe, an overflow weir and a water stabilizing grating are sequentially arranged inside the water inlet chamber from upstream side to downstream side; the water inlet pipe is arranged at the bottom of the water inlet chamber, and is perpendicular to a water flow direction inside the water inlet chamber; the water inlet pipe penetrates through the sidewall of the water inlet chamber and is connected to a water supply pipe outside the water inlet chamber; the tail end of the water inlet pipe is sealed, and a water flow runs into the water inlet chamber by virtue of a plurality of water outlet holes which are uniformly distributed in the lower surface of the water inlet pipe; the overflow weir and the water stabilizing grating are parallel to the water inlet pipe; the width of the overflow weir is identical to the width of the water inlet chamber; the height of the overflow weir is less than the height of the water inlet chamber; the width of the water stabilizing grating is identical to the width of the water inlet chamber; the height of the water stabilizing grating is identical to the height of the water inlet chamber; and a plurality of drain holes are arranged at the bottom of the water stabilizing grating.

Description

technical field [0001] The invention relates to a composite hole-type water stabilizing grid device, which is especially suitable for stabilizing water supply in laboratories. Background technique [0002] In the hydraulic experiment, there is uneven inflow distribution in the water flow to the experimental model area, and the water flow needs to be adjusted for a long distance in the process of achieving a stable and uniform flow, and the effect is not good. Set up a flow stabilization measure at the outlet of the outflow pipe , in order to quickly obtain a uniform and stable water flow state, is a key issue in the model test. [0003] In almost all water flow model tests such as hydraulic engineering, river engineering, and port engineering, it is required that the inflow of the model water flow is evenly distributed and the water flow is stable (small fluctuations in the water surface). Usually, the laboratory water supply system or the water pump is simply introduced in...
