The invention relates to the technical field of experimental equipment for non-uniform flow surface curves. The invention discloses a variable-slope water tank test system, which includes a water tank, a water pump device, a water storage tank, and a thin-walled weir. The water device is connected to the upper channel for the pumped water to flow out obliquely, the middle channel for the water flow in the upper channel to flow in and then obliquely out, and the lower channel for the water flow in the middle channel to flow in. The thin-walled weir is arranged in the upper channel close to the upper water flow The position of the outlet, the middle water outlet of the middle channel is provided with a water flow control structure to control the interruption of the middle water flow, the middle water inlet of the middle channel is provided with a water baffle, and the middle channel is close to the middle water outlet. The location has a culvert. The invention can accurately analyze and calculate the water surface curve, thereby providing accurate reference experiment data for open channel design and having high reference value.
Description
technical field [0001] The invention relates to the technical field of experimental equipment for non-uniform flow surface curves, in particular to a variable-slope water tank test system. Background technique [0002] Open channel is a channel with free surface water flow, which can be divided into natural open channel and artificial open channel according to its formation. Analyzing and calculating the water surface curve is a key issue in the design of open channels and related buildings. Among them, since the water surface curve of the uniform flow in the open channel is a straight line parallel to the bottom of the channel, it is relatively simple, so the water surface curve of the open channel is mainly studied for non-uniform flow. Non-uniform flow refers to the water flow in which the flow velocity and direction of the fluid are constantly changing along the way. [0003] The variable slope of the variable slope flume test system uses the thin-walled weir as the cor...
