DETAILED DESCRIPTION

[0034] The technical solutions in the embodiments of the application will be described clearly and completely below in conjunction with the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, rather than all the embodiments of the application. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative work are involved in the protection scope of the application.

[0035] like Figures 1-8 As shown, this embodiment proposes a multifunctional verification base, including a base plate 1. A support mechanism 2 for supporting the base plate 1 is fixedly connected to the bottom of the base plate 1. A movable platform 3 is provided above the base plate 1. A lifting mechanism 4 is provided at the bottom of the movable platform 3. The lifting mechanism 4 includes four internal threaded sleeves 41 rotatably connected to the four corners of the movable platform 3. Each of the four internal threaded sleeves 41 is threaded with a through screw 42. A rotating cap 43 is fixedly connected to the bottom end of each of the four screws 42. An angle adjustment component 47 for adjusting the tilt angle of the screw 42 is provided at the bottom end of three of the screws 42. A test frame 5 is fixedly connected to the top of the movable platform 3. An upper positioning mechanism 6 for positioning the upper end of the photovoltaic bracket is provided at the top of the test frame 5. A lower positioning mechanism 7 for positioning the lower end of the photovoltaic bracket is provided at the bottom end of the test frame 5.

[0036] During testing, the photovoltaic bracket is placed inside the test frame 5, and then the upper and lower ends of the photovoltaic bracket are positioned and fixed by the upper positioning mechanism 6 and the lower positioning mechanism 7 respectively. By rotating the rotating cap 43, the inner threaded sleeve 41 and the screw 42 rotate relative to each other, so that the inner threaded sleeve 41 can move in the vertical direction. This allows the movable platform 3 to move in the vertical direction, thereby realizing the height adjustment of the movable platform 3 and the test frame 5, and thus meeting the testing requirements of different heights of the actual photovoltaic bracket.

[0037] Furthermore, the top of the base plate 1 is provided with four fixing seats 46 corresponding to the four screws 42. Each of the four fixing seats 46 has a locking screw 451 that penetrates the base plate 1. Each of the four locking screws 451 has a pad 44 fitted onto it. The bottom end of each of the four locking screws 451 is threaded with a locking nut 452 for pressing the pad 44 against the bottom wall of the base plate 1. Both ends of the base plate 1 have several mounting holes 8 that match the locking screws 451. The mounting holes 8 at the same end are equidistantly distributed along the length of the base plate 1. By adjusting the position of the locking screws 451, the position of the movable stage 3 can be adjusted, allowing the test frame 5 to be installed at any position on the base plate 1. This enables the test position to be adjusted according to actual testing requirements, providing strong versatility.

[0038] Furthermore, the angle adjustment assembly 47 includes a rotating seat 471 rotatably connected to the inner side of the fixed seat 46. A mounting seat 472 is fixedly connected to the top of the rotating seat 471. A connecting block 473 is rotatably connected to the inner side of the mounting seat 472. The top of the connecting block 473 is fixedly connected to the bottom end of the corresponding screw 42. A limiting member 474 for positioning the rotating seat 471 is provided on the outer side of the fixed seat 46.

[0039] After determining the height of the movable platform 3, the two rotating seats 471 on the same side of the movable platform 3 are rotated so that the corresponding two mounting seats 472 rotate in the same direction and remain parallel. Then, the two internal threaded sleeves 41 on the other side of the movable platform 3 are rotated so that the other side of the movable platform 3 can move up or down. This allows the movable platform 3 to tilt at a certain angle, which in turn keeps the test frame 5 tilted, thus allowing the photovoltaic support inside the test frame 5 to be tilted for testing, greatly improving the functionality of the test frame 5.

[0040] Furthermore, the limiting member 474 includes a limiting rod 4741 that penetrates the side wall of the fixed seat 46. The limiting rod 4741 is slidably connected to the fixed seat 46. One end of the limiting rod 4741 is slidably engaged with the rotating seat 471. The other end of the rotating seat 471 is fixedly connected to a pull block 4742. The outer wall of the rotating seat 471 is provided with several limiting grooves 4746 that are equally distributed around the rotating seat 471. The limiting rod 4741 can slide and engage with any one of the limiting grooves 4746. A slider 4743 is fixedly connected to the middle of the limiting rod 4741. The inner wall of the fixed seat 46 is provided with a receiving groove 4744 that slides and engages with the slider 4743. A spring 4745 is sleeved on the limiting rod 4741. One end of the spring 4745 abuts against the slider 4743, and the other end of the spring 4745 abuts against the inner wall of the receiving groove 4744.

[0041] By pulling the pull block 4742 outward, the limiting rod 4741 is disengaged from the corresponding rotating seat 471. At this time, the spring 4745 is compressed and accumulates potential energy, which allows the rotating seat 471 to contact the restriction and rotate. After the rotating seat 471 is in a fixed position, by releasing the pull block 4742, the spring 4745 releases its potential energy, causing the limiting rod 4741 to slide in the opposite direction and cooperate with the limiting groove 4746 of the rotating seat 471. This allows the rotating seat 471 to remain stable in the current position.

[0042] When it is necessary to adjust the angle of the test frame 5, the two rotating seats 471 on the same side of the movable platform 3 are rotated so that the corresponding two mounting seats 472 rotate in the same direction and the two mounting seats 472 remain parallel. Then, the two internal threaded sleeves 41 on the other side of the movable platform 3 are rotated so that the other side of the movable platform 3 can move up or down. This allows the movable platform 3 to tilt at a certain angle, which in turn keeps the test frame 5 tilted.

[0043] Furthermore, the support mechanism 2 includes a grid plate 21 fixedly connected to the bottom of the base plate 1. Each of the four corners of the bottom of the grid plate 21 is fixedly connected to a fixing plate 22, and each of the four fixing plates 22 is fixedly connected to a support column 23. Lifting holes 24 are provided at both ends of the base plate 1. The grid plate 21 can improve the support strength of the base plate 1, and the lifting holes 24 facilitate the hoisting and transfer of the entire base, thus making it suitable for different testing scenarios.

[0044] Furthermore, the upper positioning mechanism 6 includes a positioning plate 61 fixedly connected to the top of the test base 5. The outer edge of the positioning plate 61 has several grooves 65 evenly distributed around its center. Sliding blocks 62 are slidably connected within four of the grooves 65 symmetrically distributed around the center of the positioning plate 61. Positioning bolts 63 are provided on the inner sides of each of the four sliding blocks 62 to fix them to the positioning plate 61. Clamping blocks are fixedly connected to the top of each of the four sliding blocks 62. 64; The lower positioning mechanism 7 includes a positioning plate 71 fixedly connected to the bottom of the test base 5. The outer edge of the positioning plate 71 is provided with several sliding grooves 75 that are equally distributed around the center of the positioning plate 71. Sliding blocks 72 are slidably connected in four of the sliding grooves 75 that are symmetrically distributed along the center of the positioning plate 71. The inner side of each of the four sliding blocks 72 is provided with positioning bolts 73 for fixing the sliding blocks 72 to the positioning plate 71. Clamping blocks 74 are fixedly connected to the top of each of the four sliding blocks 72.

[0045] Working principle: During testing, the photovoltaic bracket is placed inside the test frame 5. Then, the positions of the four sliders 62 are adjusted to match the size of the photovoltaic bracket, so that the clamping block 64 can clamp the upper end of the photovoltaic bracket, and then it is fixed by the positioning bolt 63. Then, the position of the slider 72 is adjusted to match the size of the photovoltaic bracket, so that the clamping block 74 clamps the lower end of the photovoltaic bracket, and finally it is fixed by the positioning bolt 73. This achieves the positioning of photovoltaic brackets of different sizes. The use of bolts to fix the whole structure can ensure the stability of the overall structure and improve the versatility of the whole device.

[0046] After determining the height of the movable platform 3, the two rotating seats 471 on the same side of the movable platform 3 are rotated so that the corresponding two mounting seats 472 rotate in the same direction and remain parallel. Then, the two internal threaded sleeves 41 on the other side of the movable platform 3 are rotated so that the other side of the movable platform 3 can move up or down. This allows the movable platform 3 to tilt at a certain angle, which in turn keeps the test frame 5 tilted, thus allowing the photovoltaic support inside the test frame 5 to be tilted for testing, greatly improving the functionality of the test frame 5.

[0047] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
