Description

Technical Field

[0001] This utility model relates to the field of wind turbine testing technology, and in particular to a wind turbine testing device. Background Technology

[0002] In existing simulated electric fireplaces, there is usually a sprayer and a fan inside. The fan blows the water mist sprayed by the sprayer out of the simulated electric fireplace to simulate the smoke when the flame is burning, thereby improving the simulation effect of the simulated electric fireplace.

[0003] Before assembling a simulated electric fireplace, the fan's speed needs to be tested to ensure it has sufficient rotational speed to spray water mist from the sprayer. In existing technology, testers typically install the fan on a test bench and then use a speed sensor to measure the fan's speed to ensure it meets preset standards. This type of fan testing device generally only displays the test results to the testers through the speed sensor readings. However, because the test conditions for the fan differ significantly from the actual conditions inside a simulated electric fireplace, even if the fan speed test is successful, the simulated smoke effect produced after installation may not meet expectations. This necessitates the design team replacing the fan with a different model.

[0004] Therefore, finding a technical solution that can solve the above-mentioned technical problems has become an important research topic for those skilled in the art. Utility Model Content

With the above design, when the test fan 5 is turned on, the tester can judge whether the test fan 5 meets the design requirements by observing the flow of water mist inside the test chamber 103, thus enabling it to be adapted to a simulated electric fireplace.

[0032] Furthermore, the drainage structure in this embodiment includes a first guide plate 6 and a second guide plate 7;
