[0023] This section will describe in detail the specific embodiments of the present invention. The preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present invention, but it cannot be understood as a limitation on the scope of protection of the present invention.

[0024] Reference Figure 1-4 The utility model embodiment provides a test fixture for a photovoltaic adjustable bracket rack, which includes a base plate 1, a motor 2 is fixedly connected to the top of the base plate 1, a gear 3 is fixedly connected to the end of the output shaft of the motor 2, and the top of the gear 3 is meshed with the rack 17 to be tested. The operation of the motor 2 drives the gear 3 to rotate, and the rotating gear 3 can drive the rack 17 to be tested to move back and forth to complete the test of the rack 17 to be tested. Two positioning components for positioning the rack 17 to be tested are symmetrically provided on the top of the base plate 1;

[0025] The positioning assembly includes a fixed frame 4 fixedly connected to the top of the base plate 1 and set as an L-shaped structure, a first screw rod 5 threadedly connected to the top of the fixed frame 4, a connecting frame 6 rotatably connected to the bottom of the first screw rod 5, a U-shaped plate 7 fixedly connected to the bottom of the connecting frame 6, a mounting frame 8 fixedly connected to the top of the U-shaped plate 7 and set as a U-shaped structure, a bidirectional screw rod 9 rotatably connected to the inner side of the mounting frame 8, two movable frames 10 symmetrically threadedly connected to the outer sides of the bidirectional screw rods 9 and both set as L-shaped structures, and a connecting rod 11 inserted into one of the movable frames 10, one end of the connecting rod 11 passes through the interior of the mounting frame 8 and is fixedly connected to the end of the bidirectional screw rod 9, and rollers arranged opposite to each other are installed on the inner side of the U-shaped plate 7 and the bottom of the two movable frames 10;

[0026] The rack 17 to be tested is placed between the rollers, and the rotation of the first screw rod 5 can drive the connecting frame 6 to move downward. The downward moving connecting frame 6 can better drive the rollers on the U-shaped plate 7 to contact the upper surface of the rack 17 to be tested, and the rotating connecting rod 11 drives the bidirectional screw rod 9 to rotate. The rotating bidirectional screw rod 9 can realize the opposite movement operation of the mobile frame 10, so that the mobile frame 10 moving towards each other can synchronously drive the rollers above the mobile frame 10 to contact the two side surfaces of the rack 17 to be tested, and then under the action of the three rollers and the gear 3, the stability of the movement of the rack 17 to be tested can be guaranteed. By driving the rack 17 to be tested to move back and forth for testing, it is beneficial to evaluate the long-term performance of the rack of the bracket to ensure the stability and reliability of the operation of the photovoltaic system.

[0027] The positioning assembly also includes a guide rod 12, which is slidably connected to the inside of the fixed frame 4 and the bottom is fixedly connected to the top of the connecting frame 6. When the first screw rod 5 rotates to drive the connecting frame 6 to move up and down, it drives the guide rod 12 to slide inside the fixed frame 4, which is beneficial to ensuring the stability of the movement of the connecting frame 6. The bottom of the top of the mobile frame 10 is slidably connected to the top of the corresponding end of the mounting frame 8. When the mobile frame 10 moves under the action of the rotating bidirectional screw rod 9, it slides in cooperation with the mounting frame 8, which is beneficial to ensuring the stability of the movement of the mobile frame 10.

[0028] Both ends of the rack 17 to be tested are provided with a counterweight assembly, which includes a connecting plate 15 inserted into the end of the rack 17 to be tested, a counterweight plate 16 fixedly connected to the top of the connecting plate 15 and a second screw rod 14 threadedly connected to one side of the connecting plate 15. The end of the second screw rod 14 close to the rack 17 to be tested can be fitted with the outer side of the rack 17 to be tested. The connecting plate 15 is sleeved on the end of the rack 17 to be tested, and the second screw rod 14 is screwed to fit the outer side of the rack 17 to be tested, so that the counterweight plate 16 can be installed on the rack 17 to be tested. Under the action of the counterweight plate 16, it is helpful to simulate the operating state of the rack 17 to be tested when it is subjected to a certain load in actual application, so as to more accurately evaluate the performance and reliability of the rack 17 to be tested.

[0029] There is a suitable distance between the top of the mobile frame 10 and the bottom of the top of the connecting frame 6, and there is also a suitable distance between the two sides of the mobile frame 10 and the inner surface of the connecting frame 6. The distance between the top and the two sides of the mobile frame 10 can prevent the mobile frame 10 from colliding with the connecting frame 6 when moving, which is conducive to ensuring the smooth movement of the mobile frame 10.

[0030] One end of the two first screw rods 5, the connecting rod 11 and the two second screw rods 14 are fixedly connected to a knob 13. Turning the knob 13 can drive the corresponding first screw rod 5, the connecting rod 11 or the second screw rod 14 to rotate, making the rotation operation of the first screw rod 5, the connecting rod 11 and the two second screw rods 14 simpler and more convenient.

[0031] Working principle: The rack 17 to be tested is placed between the rollers, and the rotation of the first screw rod 5 can drive the connecting frame 6 to move downward. The downward moving connecting frame 6 can better drive the roller on the U-shaped plate 7 to contact the upper surface of the rack 17 to be tested, and the rotating connecting rod 11 drives the bidirectional screw rod 9 to rotate. The rotating bidirectional screw rod 9 can realize the opposite movement operation of the mobile frame 10, so that the mobile frame 10 moving towards each other can synchronously drive the rollers above the mobile frame 10 to contact the two side surfaces of the rack 17 to be tested, and then under the action of the three rollers and the gear 3, the stability of the movement of the rack 17 to be tested can be guaranteed. By driving the rack 17 to be tested to move back and forth for testing, it is beneficial to evaluate the long-term performance of the bracket rack to ensure the stability and reliability of the photovoltaic system operation.

[0032] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present invention.
