Test water tank and test method thereof

Abstract

The invention discloses a test water tank and a test method thereof. The test water tank comprises a water inlet tank, a water tank with a turning section, a water outlet tank, a water storage tank, a water pump and tracer balls. The water inlet tank is provided with a water inlet and a first rectangular thin-wall weir. The water outlet tank is provided with a water outlet and a second rectangular thin-wall weir. The water inlet tank, the water tank with a turning section and the water outlet tank are connected in sequence. The water storage tank is connected with the water inlet and the water outlet through connecting pipes. The water pump is disposed on the connecting pipe between the water inlet tank and the water storage tank. The test want tank is simple in structure and low in cost, and has many functions. The water inlet and outlet flow in the water tank is controlled accurately in water level measuring and vertical line average flow velocity measuring tests, thus guaranteeing that a test condition is constant flow. Flow can be obtained through a formula as long as water heads on thin-wall weirs are measured. Water flow trajectories are displayed through the tracer balls to describe water current movement regulations in the turning section, and phenomena are clear. The tracer balls will not affect water quality, recovered by a perforated baffle plate, and can be recycled.

Description

Technical field [0001] The invention relates to a test water tank and a test method thereof, in particular to a test water tank and a test method thereof that can accurately control the flow rate and clearly observe the flow state of the water flow. Background technique [0002] Colleges and universities with a major in port and shipping need to deepen students' understanding of the course knowledge of hydraulics and river dynamics through water flow experiments. The existing experimental equipment in some colleges and universities can only meet some basic tasks, such as adding water directly from the pump to the test tank, and measuring the water level of a certain section of the tank on the left, center, and right by a ruler, respectively. Set up a propeller-type flow meter to measure the average vertical velocity, and drop red ink or sawdust into the sink to observe the flow state of the water. In the current test process, the water inlet and outlet flow of the water tank is ...

AI Technical Summary

Problems solved by technology

In the existing test process, the flow rate of the water inlet and outlet of the water tank was not measured to ensure the constant water flow. If the water flow is not constant, the statistical law of the water flow measured in the test will have no practical significance

In addition, the added red ink and sawdust are difficult to separate out of the water, which is not easy to recycle, and after a long time of storage, it is easy to make the water tank stick red or produce peculiar smell
