[0033] The core of the present utility model is to provide a temperature test auxiliary tooling and a photovoltaic module temperature test device, which can ensure stable fitting between the temperature probe and the component to be measured and accurate test results.

[0034] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0035] Please refer to Figure 1 、 Figure 3 and Figure 5 , in this implementation manner, the temperature test auxiliary tooling includes:

[0036] Slide rail 1 and sliding assembly 2;

[0037] The slide rail 1 is provided with a chute 11, and the sliding assembly 2 is movably installed on the chute 11; both ends of the slide rail 1 are respectively connected and matched with the photovoltaic frames 32 on both sides of the photovoltaic panel 31, and the slide rail 1 is telescopic to adapt to the photovoltaic frame 32;

[0038] The sliding assembly 2 includes a sliding body 21, a first elastic component 22 and a supporting component 23. The sliding body 21 is installed on the slide groove 11. The first elastic component 22 and the supporting component 23 are both installed on the side of the sliding body 21 close to the photovoltaic panel 31. One end of the first elastic component 22 abuts against the sliding body 21, and the other end abuts against the supporting component 23. The supporting component 23 can compress the first elastic component 22 to press the temperature probe 4 against the surface of the photovoltaic panel 31.

[0039] Specifically, the slide rail 1 is made of metal, which has high strength and the slide groove 11 is easy to process; the slide rail 1 is installed between the photovoltaic frames 32 on both sides of the photovoltaic panel 31, that is, the slide rail 1 spans the photovoltaic frames 32 on both sides of the photovoltaic panel 31, and there is a certain distance between the slide rail 1 and the photovoltaic panel 31, which is convenient for the installation of the sliding assembly 2; the sliding body 21 in the sliding assembly 2 is also made of metal, which has high strength and is easy to process; the supporting component 23 should be a high-temperature resistant component to avoid performance changes caused by the increase in temperature of the photovoltaic panel 31; further, the sliding body 21 and the first elastic component 22 should also be high-temperature resistant components to ensure stability in use and improve reliability. The photovoltaic frame 32 is installed on the back of the photovoltaic panel 31, and the auxiliary tooling is also located on the back of the photovoltaic panel 31.

[0040] The temperature testing auxiliary tooling provided by the utility model is adaptable to photovoltaic frames 32 of different sizes through the retractable setting of the slide rail 1; the slide rail 1 provides support for the movement of the sliding component 2, and the sliding component 2 can move to a suitable position on the slide rail 1, and then use the cooperation of the first elastic component 22 and the supporting component 23 to press the temperature probe 4 on the surface of the photovoltaic panel 31, so as to detect the hot spot temperature of the photovoltaic panel 31; the auxiliary tooling can firmly fix the temperature probe 4 on the surface of the photovoltaic panel 31, so as to make the temperature test more accurate; and it is easy to operate, low in production cost, and reliable in use.

[0041] In some embodiments, Figure 2 As shown, both ends of the slide rail 1 are provided with open slots 12, and the open slots 12 are engaged with the photovoltaic frame 32; the gap width of the open slots 12 should be compatible with the thickness of the bent edge of the photovoltaic frame 32, so as to reduce the shaking between the slide rail 1 and the photovoltaic frame 32 and ensure stability.

[0042] In some embodiments, the opening slot 12 is connected to the slide slot 11, and the sliding body 21 slides into the slide slot 11 from the opening slot 12. The opening slot 12 is located at the end of the slide rail 1. The depth of the opening slot 12 in the extension direction of the slide rail 1 can be appropriately increased to adapt to different models of photovoltaic frames 32.

[0043] In some embodiments, Figure 3 and Figure 4As shown, the slide rail 1 includes a first slide rail body 13, a second slide rail body 14, and a telescopic rod 15. The two ends of the telescopic rod 15 are respectively connected to the first slide rail body 13 and the second slide rail body 14. The telescopic rod 15 can be telescoped to change the distance between the first slide rail body 13 and the second slide rail body 14. Specifically, the distance between the first slide rail body 13 and the second slide rail body 14 changes with the change of the length of the telescopic rod 15 itself. The two ends of the telescopic rod 15 are fixedly connected to both the first slide rail body 13 and the second slide rail body 14, and this method has better stability. Through the setting of the telescopic rod 15, on the one hand, it can be adapted to photovoltaic modules 3 of different sizes and models. On the other hand, through the telescoping of the telescopic rod 15, the disassembly and assembly of the slide rail 1 on the photovoltaic frame 32 can be completed, and the operation is convenient.

[0044] In some embodiments, the slide rail 1 further includes a second elastic member 16. The two ends of the second elastic member 16 are respectively abutted against the first slide rail body 13 and the second slide rail body 14. The second elastic member 16 can be a spring, which is convenient to obtain materials and install. Through the change of the length of the telescopic rod 15, the compression degree of the second elastic member 16 can be changed. The second elastic member 16 uses its own elasticity to provide a force for the first slide rail body 13 and the second slide rail body 14 to move away from each other, improving stability.

[0045] In some embodiments, one end of the telescopic rod 15 is fixedly connected to one of the first slide rail body 13 or the second slide rail body 14, and the other end of the telescopic rod 15 is movably connected to the other of the first slide rail body 13 or the second slide rail body 14. That is, the change in the distance between the first slide rail body 13 and the second slide rail body 14 is achieved by the change in the position of the telescopic rod 15 relative to the first slide rail body 13 or the second slide rail body 14, rather than the change in the length of the telescopic rod 15 itself. This method has lower manufacturing costs.

[0046] In some embodiments, a chamber is provided in the first slide rail body 13 and / or the second slide rail body 14. The end of the telescopic rod 15 is inserted into the chamber. The second elastic member 16 is sleeved on the telescopic rod 15, and the second elastic member 16 abuts against the end faces of the first slide rail body 13 and the second slide rail body 14. Specifically, the telescopic rod 15 can be inserted into the chamber and move in the chamber, or the two ends of the telescopic rod 15 are fixed in the chamber, and then the distance between the first slide rail body 13 and the second slide rail body 14 is changed by its own telescoping.

[0047] In some embodiments, such as Figure 6As shown in the figure, the support member 23 is a high-temperature resistant elastic member. A convex portion 231 is provided on the side of the support member 23 facing away from the sliding body 21. Specifically, the support member 23 can be made of high-temperature resistant rubber. Through the setting of the convex portion 231, the stability of the temperature probe 4 can be ensured, and the temperature probe 4 can be prevented from falling due to the deformation of the support member 23. Further, the middle of the convex portion 231 is a plane, and the periphery is an arc surface. With such a setting, the middle of the convex portion 231 can better fit the temperature probe 4, improving the friction force between the support member 23 and the temperature probe 4, and further enhancing the position stability of the temperature probe 4.

[0048] In some embodiments, the sliding body 21 includes a base 211 and a connecting column 212. Limiting edges 2111 are provided on both sides of the base 211. Chute grooves 11 are provided on both sides of the slide rail 1, and the limiting edges 2111 are placed into the corresponding chute grooves 11. The connecting column 212 is located on the side of the base 211 facing away from the slide rail 1. The first elastic member 22 is sleeved on the connecting column 212, and the support member 23 is movably connected to the connecting column 212. Specifically, the base 211 and the connecting column 212 can be an integrally formed structure, or the connecting column 212 can be welded and fixed to the base 211. The base 211 has a U-shaped structure. The two legs of the base 211 extend and bend to form the limiting edges 2111, and the limiting edges 2111 are placed into the chute grooves 11 and slide in the chute grooves 11. Through the setting of the base 211, the moving stability between the sliding body 21 and the slide rail 1 is better. Moreover, when the sliding body 21 slides into the opening card slots 12 at both ends of the slide rail 1, the assembly is convenient. After the slide rail 1 is matched with the component frame, the sliding body 21 cannot be disengaged from the opening card slots 12, and the connection is stable. The first elastic member 22 can be a spring, which has good elasticity and is convenient for obtaining materials. The first elastic member 22 is sleeved on the connecting column 212.

[0049] In some embodiments, as Figure 6 shown, a connection hole 232 is provided on the support member 23, and the connection hole 232 is a blind hole. The connecting column 212 is inserted into the blind hole, and the insertion depth of the connecting column 212 into the blind hole is adjustable. Specifically, through the setting of the blind hole, conditions are provided for the movement of the support member 23 on the connecting column 212. When the temperature probe 4 needs to be installed, by pushing the support member 23, the support member 23 moves towards the base 211, the insertion depth of the connecting column 212 into the blind hole increases, and the first elastic member 22 is compressed. After the temperature probe 4 is installed in place, the support member 23 is released, and the first elastic member 22 elongates, pushing the support member 23 to press the temperature probe 4 tightly on the photovoltaic panel 31, and the connection is stable.

[0050] In a specific embodiment, chute grooves 11 and opening card slots 12 are provided on the slide rail 1. When assembling this auxiliary tooling, as Figure 7 and Figure 8As shown, first place the photovoltaic module 3 vertically in the light attenuation box, with the back of the photovoltaic module 3 facing the operator, that is, the photovoltaic bracket of the photovoltaic module 3 facing the operator. Shorten the slide rail 1 and compress the second elastic member 16 to reduce the length of the slide rail 1 until the open slot 12 at both ends of the slide rail 1 is engaged with the bent edges of the photovoltaic frame 32 on both sides of the photovoltaic panel 31. Then, under the action of the second elastic member 16, the slide rail 1 extends to firmly fix the slide rail 1 on the photovoltaic frame 32 on both sides of the photovoltaic panel 31. Then place the temperature probe 4 between the support member 23 and the photovoltaic panel 31. Under the elastic force of the first elastic member 22, the support member 23 is subjected to a force towards the photovoltaic panel 31, thereby fixing the temperature probe 4 on the back of the photovoltaic panel 31. Then lay the photovoltaic module 3 flat, short-circuit the wires of the photovoltaic module 3, set the light intensity and temperature, and then the temperature test can be carried out.

[0051] In addition to the above temperature test auxiliary tooling, the present invention also provides a temperature test device for a photovoltaic module 3 including the above temperature test auxiliary tooling. For the structures of other parts of the temperature test device for the photovoltaic module 3, please refer to the prior art and will not be elaborated herein.
