[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0040] Reference Figure 1 , Figure 3 and Figure 4 An embodiment of this utility model provides a photovoltaic panel testing device, including a frame 1. Threaded blocks 3 are equidistantly slidably connected to the upper left side of the frame 1. Fixed frames 4 are fixedly connected to the right sides of both threaded blocks 3. Detection plates 5 are slidably connected to the inner sides of both fixed frames 4. The fixed frames 4 are used to fix the detection plates 5. Circular grooves 7 are opened at the front and rear ends of the left side of both detection plates 5. Springs 8 are fixedly connected inside the multiple circular grooves 7. Circular buckles 9 are fixedly connected to the ends of the multiple springs 8. The detection plates 5 are fixed in the fixed frames 4 by the springs 8 and the circular buckles 9. Screws 6 are threadedly connected to the front and rear ends of the left side of both fixed frames 4. A power mechanism 2 is installed on the left side of the frame 1. The power mechanism 2 is used to control the movement of the detection plates 5. Limiting plates 10 are fixedly connected to the front and rear ends of the upper left side of the frame 1. Sliding grooves 11 are opened on the adjacent sides of the two limiting plates 10. The fixed frames 4 slide within the range of the limiting plates 10.
[0041] Specifically, in the detailed process of photovoltaic panel testing, when encountering relatively small photovoltaic panels, to ensure testing accuracy, the screws 6 used to fix the fixing frame 4 and the test piece 5 can be unscrewed first. Then, using the groove designed on the fixing frame 4, the original test piece 5 is pulled outwards, and a test piece 5 adapted to the current photovoltaic panel size is pushed into its proper position through the groove path. When the test piece 5 is pushed into the appropriate position, the round buckle 9 fixed on the test piece 5 by the spring 8 will lock into the groove of the fixing frame 4, and then the screws 6 can be screwed back in. This achieves the effect of quickly replacing the test piece 5, thereby improving the versatility of the photovoltaic panel testing equipment. The cooperation between the limiting plate 10 and the slide 11 restricts the movement range of the fixing frame 4, ensuring the stable operation of the equipment.
[0042] Reference Figure 2 and Figure 5 The power mechanism 2 includes a motor 201, which is fixedly connected to the left side of the middle part of the frame 1. A bevel gear rod 202 is fixedly connected to the output end of the motor 201. A bidirectional threaded rod 204 is threadedly connected to the middle part of the threaded block 3. A bevel gear rod 203 is fixedly connected to the bottom end of the bidirectional threaded rod 204. The bevel gear rod 203 meshes with the bevel gear rod 202. The motor 201 drives the bidirectional threaded rod 204 through the bevel gear rod 202 and the bevel gear rod 203. The left side of the frame 1... A square groove 205 is provided at the upper end. Guide rails 206 are fixedly connected at equal intervals in the upper middle part of the frame 1. The threaded block 3 and the fixed frame 4 are guided through the square groove 205 and the guide rails 206. A guardrail 16 is fixedly connected in the lower middle part of the frame 1. A base plate 17 is fixedly connected at the bottom of the guardrail 16. The guardrail 16 and the base plate 17 provide protection for the motor 201. A hinge 18 is threadedly connected to the rear left end of the guardrail 16. A gate 19 is threadedly connected to the rear left end of the hinge 18. The gate 19 works with the hinge 18 to achieve the opening and closing effect.
[0043] Specifically, after the battery cell to be tested is transported to the test piece 5 by the conveyor belt, the motor 201 provides power to drive the rotation of the first bevel gear rod 202, which in turn drives the rotation of the second bevel gear rod 203, which in turn drives the rotation of the bidirectional threaded rod 204 fixed on it. The rotation of the bidirectional threaded rod 204 can control the mutual convergence and separation of the two fixed frames 4 with the test piece 5 through the two threaded blocks 3, while the guide rail 206 realizes the effect of guiding the movement trajectory of the fixed frames 4. The guardrail 16 and the base plate 17 outside the motor 201 provide protection, and the gate 19 is locked by the hinge 18 to facilitate the maintenance of the motor 201. The model of the motor 201 is 28BYJ-48.
[0044] Reference Figure 1 and Figure 2The top of the frame 1 is equipped with a top rail 12, and screws 13 are threaded to the four corners of the top rail 12. The top rail 12 provides protection for the equipment. X-shaped frames 14 are installed on the left and right sides of the lower middle part of the frame 1. Screws 15 are threaded to the four corners of the two X-shaped frames 14. The X-shaped frames 14 and screws 15 provide stability for the frame 1. Bearings 20 are fixedly connected to the four corners of the bottom of the frame 1. Pulleys 21 are fixedly connected to the bottom of the multiple bearings 20. The pulleys 21 facilitate the movement of the equipment.
[0045] Specifically, the top rail 12 is firmly fixed to the equipment by screw 2 13, thereby providing effective protection for the top of the overall equipment. The X-shaped frame 14 fixed to both sides of the photovoltaic panel testing equipment by screw 3 15 can make the frame 1 more stable and prevent it from loosening due to accidents or long-term operation. The pulley 21 and bearing 20 enable convenient multi-directional movement of the equipment.
[0046] Working principle: When testing photovoltaic panels, if a smaller photovoltaic panel is encountered, the screws 6 used to fix the fixing frame 4 and the test piece 5 can be unscrewed first; then the test piece 5 can be pulled out through the groove of the fixing frame 4, and then a suitable test piece 5 can be pushed in through the groove of the fixing frame 4; when the test piece 5 is pushed into the appropriate position, the round buckle 9 fixed on the test piece 5 by the spring 8 will lock into the groove of the fixing frame 4, and then the screws 6 can be screwed back in; this achieves the effect of quickly replacing the test piece 5, thereby improving the versatility of the photovoltaic panel testing equipment;
[0047] When the battery cell to be tested is transported to the test piece 5 by the conveyor belt, the motor 201 provides power to drive the rotation of the first bevel gear rod 202, which in turn drives the rotation of the second bevel gear rod 203, which in turn drives the rotation of the bidirectional threaded rod 204 fixed on it. The rotation of the bidirectional threaded rod 204 can control the two fixed frames 4 to bring the test piece 5 together and separate through the two threaded blocks 3, while the guide rail 206 realizes the effect of guiding the movement trajectory of the fixed frames 4.
[0048] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
