Embodiment Construction

[0019] Below in conjunction with accompanying drawing, the present invention is described in detail:

[0020] Such as figure 1 As shown, the present invention provides a vertical circulating water tank for testing water turbines. The water tank 1 includes a drainage section 2 and a working section 3, and a first vertical water tank is arranged between the drainage section 2 and the working section 3. A straight water flow section 41 and a second vertical water flow section 42, a water driving mechanism 5 is arranged between the drainage section 2 and the first vertical water flow section 41, and the working section 3 connects with the trapezoidal water inlet 6 The second vertical water flow section 42 is connected. The trapezoidal water inlet is a contraction section, which has the effect of accelerating water flow. The water driving mechanism 5 includes a motor 51, an output shaft 52 and a rotating shaft 53 with two propellers 54, the motor 51 is connected to the rotating s...

Abstract

The invention discloses a vertical circulating water tank for water turbine test. The water tank comprises a drainage section and a work section. A first vertical water flow section and a second vertical water flow section are arranged between the drainage section and the work section. A water driving mechanism is arranged between the drainage section and the first vertical water flow section. The work section is connected with the second vertical water flow section through a trapezoidal water inlet. The water tank can provide a relatively stable water flow. By combining the water tank with tidal water turbine test, the experiment process is simplified, and an accurate experiment result is easier to obtain.

Description

technical field [0001] The invention relates to the field of tidal current energy test research, in particular to a tidal current energy test device combining a vertical circulating water tank and a water turbine. Background technique [0002] As a clean and renewable energy source, ocean energy is not only rich in resources, but also has little impact on the environment and will not produce three wastes. It is of great significance to alleviate the energy crisis and environmental pollution. [0003] Tidal current energy experiments mostly use circulating water tanks, and traditional circulating water tanks mostly use water pumps as the power system, and there are many disadvantages in using water pumps as the propulsion system of circulating water tanks. First of all, the high energy consumption and low efficiency of the water pump make the test cost relatively high; moreover, the adjustment of pumping and drainage speed of the water pump is not flexible, which reduces the ...
