[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-3 The utility model provides a technical solution: a photovoltaic module LID test device, comprising a body 1, a door 2 is hingedly connected to the front of the body 1 through a hinge, a moving component 200 is installed inside the body 1 for moving the photovoltaic module after the LID test is completed, a control component 300 for controlling the temperature and humidity of the body 1 is installed inside the body 1, and a humidifying component 400 is installed on the top of the body 1;

[0024] Through the coordinated use of the body 1, the mobile component 200, the control component 300 and the humidification component 400, during actual use, there is no need to open the device to dissipate heat from the photovoltaic components used for LID testing, thereby effectively avoiding large temperature changes inside the device when replacing the photovoltaic components, and thus there is no need to reheat and humidify the inside of the device, thereby improving the efficiency of LID testing of photovoltaic components, reducing energy waste, and improving the practicality of the photovoltaic component LID testing device.

[0025] In this embodiment, the moving assembly 200 is a structure that drives the photovoltaic assembly to move.

[0026] like Figure 1 , Figure 2 and Figure 3As shown, the moving assembly 200 includes a placement plate 201 slidably connected to the inner bottom wall of the body 1, a vertical plate 202 is fixed to the back of the placement plate 201, connecting rods 203 are fixed to the left and right sides of the vertical plate 202, sliders 204 are fixed to the opposite ends of the two connecting rods 203, the sliders 204 are internally slidably connected to limit rods 205, the left and right inner walls of the body 1 are provided with sliding grooves 206, two hydraulic rods 207 are fixed to the back of the vertical plate 202, and an observation window 208 is fixed to the inside of the machine door 2.

[0027] It should be noted that the front and back sides of the limit rod 205 are respectively fixed to the inner front side wall and the inner rear side wall of the slide groove 206, and the slider 204 is slidably connected to the inside of the slide groove 206, ensuring that the vertical plate 202 and the placement plate 201 are more stable during the forward and backward movement through the connecting rod 203, the slider 204 and the limit rod 205, thereby ensuring the stability of the photovoltaic components and other equipment required for LID testing placed on the placement plate 201.

[0028] In addition, the back side of the hydraulic rod 207 is fixed to the inner rear side wall of the machine body 1, and the hydraulic rod 207 is fixed. The length of the vertical plate 202 is equal to the length of the machine door 2, and the height of the vertical plate 202 is equal to the height of the machine body 2, ensuring that the vertical plate 202 can effectively replace the machine door 2, thereby reducing energy leakage.

[0029] In addition, the hydraulic rod 207 is a high temperature resistant hydraulic rod, and the observation window 208 is a high temperature resistant glass, which ensures that the hydraulic rod 207 and the observation window 208 can work correctly and effectively under high temperature.

[0030] In this embodiment, the control component 300 is a structure for controlling the fixed temperature and humidity in the body 1.

[0031] like Figure 1 and Figure 2 As shown, the control component 300 includes a controller 301 fixed to the left side of the body 1, a temperature and humidity indicator 302 is fixed to the top of the body 1, a humidifier 303 is fixed to the top of the body 1, two fixed columns 304 are fixed to the left and right inner walls of the body 1, and an electric heating plate 305 is fixed between the opposite sides of the two fixed columns 304 on the left and right sides.

[0032] It should be noted that the bottom of the temperature and humidity indicator 302 passes through the body 1 and extends to the inside of the body 1, ensuring that the temperature and humidity indicator 302 can accurately and effectively indicate the temperature and humidity in the body 1.

[0033] In addition, the controller 301 is electrically connected to the humidifier 303 and the electric heating plate 305 respectively, ensuring that the humidifier 303 and the electric heating plate 305 can be controlled to switch on and off by the controller 301 .

[0034] In this embodiment, the humidifying component 400 is a structure for humidifying the body 1 .

[0036] It should be noted that the top of the support column 405 is fixed to the inner top wall of the body 1, and the buffer tube 403 is fixed more stably through the support column 405. A water supply pipe is fixed on the top of the water tank 401 to facilitate water supply to the water tank 401.

[0037] In addition, the water inlet of the humidifier 303 penetrates the water storage tank 401 and extends to the inside of the water storage tank 401, ensuring that the water in the water storage tank 401 can enter the humidifier 303 and be converted into water vapor.

[0038] The working principle of the above embodiment is:

[0039] When in use, open the machine door 2, place the photovoltaic components that need to be tested for LID and other equipment required for the test process on the placement plate 201, then turn on the electric heating plate 305 through the controller 301 to increase the temperature in the machine body 1, and turn on the humidifier 303 at the same time. The water in the water storage tank 401 is converted into water vapor through the humidifier 303 and transported to the buffer tube 403 through the connecting pipe 402, and then sprayed into the machine body 1 through the nozzle 404, so as to achieve the purpose of humidification, and then observe the temperature and humidity in the machine body 1 through the temperature and humidity indicator 302. When the temperature and humidity reach the specified value, the photovoltaic components can be tested for LID. When the test is completed, open the hydraulic rod 207 to drive The vertical plate 202 and the placement plate 201 are adjusted to move forward and backward, and the stability of the photovoltaic components on the top of the placement plate 201 is ensured by the left and right movements of the slider 204, the limit rod 205 and the connecting rod 203. At the same time, the machine door 2 is opened to take out the photovoltaic components from the machine body 1. At the same time, the vertical plate 202 replaces the machine door 2, thereby greatly reducing the energy leaked from the machine door 2. After the photovoltaic components are cooled, the vertical plate 202 and the placement plate 201 are moved into the machine body 1 after opening the hydraulic rod 207. After a short period of time, the temperature and humidity in the machine body 1 can be raised to the target value, and the LID test can be performed on the next group of photovoltaic components, thereby effectively improving the test efficiency and reducing energy waste.

[0040] Compared with the prior art, the photovoltaic module LID testing device, through the coordinated use of the body 1, the moving component 200, the control component 300 and the humidifying component 400, does not need to open the device to dissipate heat for the photovoltaic module used for LID testing during actual use, thereby effectively avoiding large temperature changes inside the device when replacing the photovoltaic module, and thus there is no need to reheat and humidify the inside of the device, thereby improving the efficiency of LID testing of the photovoltaic module and reducing energy waste, thereby improving the practicability of the photovoltaic module LID testing device and solving the problem of low practicability of the existing photovoltaic module LID testing device.
