[0020] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0021] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0022] like Figure 1-Figure 2As shown, it is a structural diagram of a simple device for detecting light leakage in a rectangular air duct provided by an embodiment of the utility model, comprising a remote control trolley body 4, a bracket 5, a light source 2 and a camera 3, wherein the remote control trolley body 4 is placed in the rectangular air duct, the bracket 5 is installed on the top of the remote control trolley body 4, and a U-shaped card slot 1 is provided in the middle of the upper surface of the bracket 5; the light source 2 is embedded in the U-shaped card slot 1, and the light source 2 uses an LED high-intensity flashlight or an LED rechargeable bulb for lighting in the rectangular air duct and detecting light leakage; the camera 3 is installed at the front end of the remote control trolley body 4 to facilitate image acquisition when the light source 2 is working; the camera 3 is lower than the light source 2, and the camera 3 and the light source 2 are also arranged horizontally along the length direction of the remote control trolley body 4.

[0023] The present application provides a simple device for detecting light leakage in rectangular air ducts, which has the characteristics of cost saving, strong applicability, simple operation and high safety. The purchase price of materials and equipment is low. For example, the high-intensity flashlight can be disassembled for lighting. The device can be used multiple times and can be applied to light leakage tests on rectangular air ducts of various materials. The device can be operated by one person. Compared with the original detection process, the device has no wires to drag, reducing the risk of electric shock.

[0024] In one example of the utility model, a tire is provided at the bottom end of the remote control car body 4. The tire is a rubber tire or an anti-skid tire, and the bottom end of the tire abuts against the inner wall of the rectangular air duct to facilitate use in rectangular air ducts of different materials.

[0025] like Figure 1 As shown, as a preferred embodiment of the utility model, a wireless transmission module is built into the remote control car body 4, and the wireless transmission module is connected to the camera 3.

[0026] In an example of the utility model, when the whole moves along the rectangular air duct, the light source 2 emits light, which is detected by the set camera 3 and the detection result is transmitted to the wireless transmission module in the remote control car body 4.

[0027] like Figure 1 As shown, as another preferred embodiment of the utility model, it also includes a display, and the display is connected to the wireless transmission module via a wireless network so as to transmit the internal scene of the rectangular air duct to the display.

[0028] In one example of the utility model, the display can be a smart phone, and an APP software matching the remote control car is installed in the smart phone, and the wireless transmission module is used to transmit the video screen to the mobile phone APP end through the wireless network to view the internal situation of the rectangular air duct in real time.

[0029] To summarize, when in use, first install the light source 2 in the U-shaped slot 1, and place the whole in the rectangular air duct. The internal situation of the air duct is transmitted to the external display (smartphone) through the camera 3. When the remote control car body 4 is driving in the rectangular air duct, it avoids through the image in the external display (smartphone), ensuring that the remote control car body 4 can travel smoothly. At the same time, it can accurately stop at each interface position of the air duct, and illuminate the inside of the rectangular air duct through the light source 2. The light leakage at the air duct interface can clearly judge the tightness of the air duct interface.
