[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] In the prior art, when sampling and recording the temperature of photovoltaic panels, workers are mostly required to hold a handheld infrared thermometer to sample and record the temperatures of multiple photovoltaic modules on the photovoltaic panels in turn, so as to compare the performance of the photovoltaic modules at different temperatures. However, this type of sampling and detection method requires workers to constantly move around to sample the temperatures of photovoltaic modules at different positions, which is time-consuming and labor-intensive, resulting in low sampling efficiency. The following describes a photovoltaic module temperature sampling device provided by some embodiments of the utility model in conjunction with the accompanying drawings.

[0023] Embodiment 1:

[0024] In order to effectively improve the temperature sampling efficiency of photovoltaic modules, combined with Figure 1 , Figure 2 and Figure 3 As shown, a temperature sampling device capable of automatically sampling and recording photovoltaic components is proposed, by arranging support mechanisms 2 at the four corners of the photovoltaic panel body 1, the support mechanism 2 is used to fix and support the entire device, and a moving mechanism 3 is arranged on the support mechanism 2. The moving mechanism 3 is used to automatically sample the temperatures of multiple photovoltaic components to save manpower, and multiple adjustment mechanisms 4 are arranged on the fixed frame 204. The adjustment mechanism 4 is used to adapt to the distance between different photovoltaic components to ensure the temperature sampling effect.

[0025] In order to avoid the staff from detecting the temperature of each photovoltaic module through a handheld thermometer 304, a mobile mechanism 3 that saves time and effort and has high sampling efficiency is proposed. By installing the thermometer 304, a sliding plate 301 is slidably connected to the top of the fixed frame 204, a sliding groove 303 is opened on one side of the sliding plate 301, and both sides of the top of the sliding plate 301 are fixedly connected to limit plates 302, a connecting plate 305 is fixedly connected to the top of the thermometer 304, a rack 307 is fixedly connected to the top of the sliding plate 301, and a gear 306 meshing with the rack 307 is rotatably connected to one side of the connecting plate 305, a screw a308 is rotatably connected between one group of fixed plates 205, and a guide rod 309 is fixedly connected between another group of fixed plates 205, a servo motor for controlling the rotation of the screw a308 is installed on one side of the fixed plate 205, and a servo motor for controlling the rotation of the gear 306 is installed on one side of the connecting plate 305. 6 is a rotating micro motor, one limit plate 302 is threadedly connected with the screw a308, and the other limit plate 302 is slidably connected with the guide rod 309. The screw a308 is controlled to rotate by the servo motor, so that the sliding plate 301 moves following the two limit plates 302, so that the thermometer 304 moves laterally along the limit rod 402. When the thermometer 304 contacts the side wall of the fixed frame 204, the micro motor drives the gear 306 to rotate, so that the gear 306 meshes and rotates on the rack 307, so that the thermometer 304 moves vertically. When it contacts the other limit rod 402, the screw a308 is controlled again to move the thermometer 304 laterally, so that the thermometer 304 moves in an "S"-shaped path in the fixed frame 204, thereby sampling the temperature of photovoltaic modules at different positions, saving time and effort, and greatly improving the sampling efficiency of the temperature of photovoltaic modules.

[0026] Embodiment 2:

[0027] On the basis of Example 1, the technical solution proposed in Example 1 is used to solve the problem in the prior art that it is time-consuming and labor-intensive for staff to use a handheld infrared thermometer to record and detect each photovoltaic component on the photovoltaic panel in turn, and the sampling efficiency is low. However, for photovoltaic panels of different specifications, the distance between two adjacent rows of photovoltaic components on their surfaces is different. If the moving path of the thermometer 304 is adjusted differently, it will affect the temperature sampling effect of the device on the photovoltaic components.

[0028] In order to enable the device to sample the temperature of photovoltaic modules with different spacings, combined with Figure 1 and Figure 4As shown, an adjustment mechanism 4 is now proposed, by setting a rotating rod 405, scale grooves 401 are provided on both sides of the fixed frame 204, a plurality of collars 403 are slidably connected to one side of the fixed frame 204, a limit rod 402 is fixedly connected to one side of the plurality of collars 403, a connection block 404 is fixedly connected to the other side of the plurality of collars 403, a screw b and a screw c are fixedly connected to both sides of the rotating rod 405, two adjacent connection blocks 404 are respectively threadedly connected to the screw b and the screw c, and the spacing between the two collars 403 is the same as that between the two adjacent rows of photovoltaic modules. The spacing between the center points is the same, the screw b and the screw c have the same thread but opposite thread directions, and the staff rotates the rotating rod 405 to make the screw b and the screw c rotate synchronously. Under the fixing action of the ring 403, the two connecting blocks 404 move relative to each other, thereby changing the moving spacing of the thermometer 304. By observing the scale groove 401, the spacing adjustment process between the two connecting blocks 404 is made more accurate, so that it is suitable for photovoltaic modules with different specifications and spacings, thereby improving the applicability of the device and ensuring the sampling effect of the device on the temperature of the photovoltaic modules.

[0029] In order to ensure the stability of the mobile mechanism 3 during the working process, a supporting mechanism 2 is proposed, which is provided by setting a fixed frame 204 and two groups of fixed plates 205. Card slots 202 are opened at the four corners of the bottom of the fixed frame 204, and multiple card slots 202 are each clamped with a card block 203. One side of the multiple card blocks 203 is fixedly connected with a support column 201. The mobile mechanism 3 is connected and fixed by the fixed frame 204, and the entire device is fixedly supported by the multiple card slots 202, the card blocks 203 and the multiple support columns 201.
