DETAILED DESCRIPTION

[0034] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

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

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

[0037] Furthermore, the top of the base plate 1 is provided with four fixing seats 46 corresponding to the four screws 42. The bottoms of the four fixing seats 46 are fixedly connected to locking screws 451 that penetrate the base plate 1. The four locking screws 451 are each sleeved with a backing plate 44. The bottom ends of the four locking screws 451 are threadedly connected to locking nuts 452 for fastening the backing plate 44 to the bottom wall of the base plate 1. Both ends of the base plate 1 are provided with a plurality of 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 platform 3 can be adjusted. In this way, the test stand 5 can be installed at any position on the base plate 1, so that the test position can be adjusted according to actual test requirements, and the test stand 5 has 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, the top of the rotating seat 471 is fixedly connected to the mounting seat 472, the inner side of the mounting seat 472 is rotatably connected to the connecting block 473, the top of the connecting block 473 is fixedly connected to the bottom end of the corresponding screw 42, and the outer side of the fixed seat 46 is provided with a limiting member 474 for positioning the rotating seat 471.

[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 to make the corresponding two mounting seats 472 rotate in the same direction and keep the two mounting seats 472 parallel, and 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 upward or downward. In this way, the movable platform 3 can be tilted at a certain angle, which also keeps the test frame 5 tilted, so that the photovoltaic bracket inside the test frame 5 can be tilted and tested, which greatly improves the functionality of the test frame 5.

[0040] Furthermore, the limiting member 474 includes a limiting rod 4741 that passes through 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, and 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 a plurality of limiting grooves 4746 distributed at equal angles around the rotating seat 471, and the limiting rod 4741 can slidably engage with any of the limiting grooves 4746. The middle part of the limiting rod 4741 is fixedly connected with a slider 4743, and the inner wall of the fixed seat 46 is provided with a receiving groove 4744 that slidably engages with the slider 4743. A spring 4745 is sleeved on the limiting rod 4741, one end of the spring 4745 is in contact with the slider 4743, and the other end of the spring 4745 is in contact with 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, so that the rotating seat 471 can contact the limit and rotate. After the rotating seat 471 is positioned, by releasing the pull block 4742, the spring 4745 releases the potential energy, causing the limiting rod 4741 to slide in the opposite direction and engage with the limiting groove 4746 of the rotating seat 471, so that the rotating seat 471 can remain stable in the current position.

[0042] When the angle of the test frame 5 needs to be adjusted, 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, and 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 upward or downward. In this way, the movable platform 3 can be tilted at a certain angle, and the test frame 5 can remain tilted.

[0043] Furthermore, the support mechanism 2 includes a grid plate 21 fixedly connected to the bottom of the base plate 1. The four corners of the bottom of the grid plate 21 are fixedly connected to fixed plates 22. The bottoms of the four fixed plates 22 are fixedly connected to pillars 23.

[0044] Furthermore, the upper positioning mechanism 6 includes a positioning plate 61 fixedly connected to the top of the test seat 5, and the outer edge of the positioning plate 61 is provided with a plurality of slide grooves 65 distributed at equal angles around the center of the positioning plate 61, wherein four slide grooves 65 symmetrically distributed along the center of the positioning plate 61 are all slidably connected to a slider 62, and the inner sides of the four sliders 62 are provided with a positioning bolt 63 for fixing the slider 62 to the positioning plate 61, and the tops of the four sliders 62 are fixedly connected with a clamping block 64; The lower positioning mechanism 7 includes a positioning plate 2 71 fixedly connected to the bottom end of the test seat 5, and the outer edge of the positioning plate 2 71 is provided with a plurality of sliding grooves 2 75 distributed at equal angles around the center of the positioning plate 2 71, wherein four sliding grooves 2 75 symmetrically distributed along the center of the positioning plate 2 71 are all slidably connected with sliders 2 72, and the inner sides of the four sliders 2 72 are provided with positioning bolts 2 73 for fixing the sliders 2 72 and the positioning plate 2 71, and the tops of the four sliders 2 72 are all fixedly connected with clamping blocks 2 74.

[0045] Working principle: During the test, the photovoltaic bracket is placed on the inner side of the test frame 5, and then the positions of the four sliders 62 are adjusted to adapt to the size of the photovoltaic bracket, so that the clamping block 64 can clamp the upper end of the photovoltaic bracket, and then fixed by the positioning bolt 63; then the position of the slider 2 72 is adjusted to adapt to the size of the photovoltaic bracket, so that the clamping block 2 74 clamps the lower end of the photovoltaic bracket, and finally fixed by the positioning bolt 2 73. In this way, the positioning of photovoltaic brackets of different sizes is achieved. The overall bolt fixation can ensure the stability of the overall structure and improve the versatility of the entire 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 to make the corresponding two mounting seats 472 rotate in the same direction and keep the two mounting seats 472 parallel, and 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 upward or downward. In this way, the movable platform 3 can be tilted at a certain angle, which also keeps the test frame 5 tilted, so that the photovoltaic bracket inside the test frame 5 can be tilted and tested, which greatly improves the functionality of the test frame 5.

[0047] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
