[0002] Explosion-proof fans are special ventilation equipment designed for various high-risk places, especially for flammable and explosive gas environments. One side of the explosion-proof fan is usually equipped with a louver for limiting ventilation. The louver can be opened and closed. The louver is opened when the explosion-proof fan is working and closed when the explosion-proof fan stops working.

[0003] In the field of explosion-proof fan manufacturing and application, the waterproof performance of explosion-proof fans is a key performance indicator. In order to ensure that explosion-proof fans can work normally under various climatic conditions, especially in the face of severe rain and snow weather, the waterproof performance of explosion-proof fans must undergo rigorous testing. The waterproofing of explosion-proof fans is mainly achieved by closing the louvers. During the water spraying test, water needs to be sprayed on the edge of the louvers to test the waterproofing effect of the fan.

[0004] At present, the traditional fan spray test is to spray the fan by the operator using a handheld nozzle, which is inefficient and requires a lot of manpower. If a large number of fans need to be tested, the operational efficiency of the fan water spray test will be seriously affected. Utility Model Content

The limiter 13 can adopt a mechanical structure, such as a combination of bolts and nuts, or in the form of an elastic clip or a clamp. The limiter 13 in the embodiment of the present application is a quick clamp, so as to ensure the stability of the fan 12 in the mounting hole and prevent the fan 12 from shaking or shifting during the water spray test.

[0035] The mounting frame 15 is provided with a nozzle 16 for spraying water on the fan 12 to be tested, and the water tank 14 is provided with a pump group 5 for connecting the nozzle 16. The pump group 5 can provide a stable water flow for the nozzle 16 to ensure the normal progress of the water spraying experiment.

[0036] like Figure 1 and Figure 3 , a control assembly 2 for controlling the position movement of the nozzle 16 is disposed on the mounting frame 15. The control assembly 2 includes a first moving seat 21 slidably disposed on the mounting frame 15, a second moving seat 22 slidably disposed on the first moving seat 21, and a moving direction of the second moving seat 22 intersects with a moving direction of the first moving seat 21. In the embodiment of the present application, the first moving seat 21 slides vertically on the mounting frame 15, and the second moving seat 22 slides horizontally on the first moving seat 21.

[0037] The mounting frame 15 is provided with a first driving unit 23 for controlling the sliding of the first movable seat 21, and the first movable seat 21 is provided with a second driving unit 24 for driving the sliding of the second movable seat 22. The first driving unit 23 and the second driving unit 24 can respectively control the first movable seat 21 and the second movable seat 22 to move in different directions, so as to achieve precise control of the position of the nozzle 16. Specifically, the first driving unit 23 and the second driving unit 24 can be a slide rail mechanism driven by a motor, and the rotation of the motor drives the movable seat on the slide rail to move linearly. In this way, the nozzle 16 can be accurately positioned and moved in three-dimensional space to meet the needs of different fan 12 water spraying tests.

[0038] like Figure 3 and Figure 4In the embodiment of the present application, the first drive unit 23 and the second drive unit 24 have the same structure.
