When the connecting angle plate moves downward to be assembled with the front support plate and the side support plate, the pressure rod moves downward, and the pressure rod squeezes the contact plate, the moving rod and the piston plate to move downward.

The magnetic force between the sliding plate and the third limit plate controls the cross bar and the movable clamp to move close to the wire.

The sliding plate and the guide sleeve slide downward along the guide rod. When the sliding plate passes over the pad, the sliding plate is controlled to move upward by the elastic force of the third elastic component. The limiting column is inserted into the limiting hole to complete the pulling limit between the side support plate and the positive support plate, and the stability between the side support plate and the positive support plate is increased.

[0043] The stabilizing airbag 5 is expanded at the same time, so that the gaps between the side support plate 1, the front support plate 2 and the photovoltaic laminate 6 are squeezed and filled by the stabilizing airbag 5, ensuring that the photovoltaic laminate 6 is more closely attached to the frame structure after assembly;

[0044] The connecting angle plate 3 is connected to the side support plate 1 and the main support plate 2 through the sliding seat 14, making the assembly operation process convenient and successful;

A piston plate 75 is slidably connected inside the piston frame 71. Two moving rods 74 are connected to the piston plate 75. A sliding sleeve 73 is slidably connected outside the moving rod 74. The sliding sleeve 73 is connected to the piston frame 71 through and through. A contact plate 77 is fixedly connected to one end of the two moving rods 74 located outside the piston frame 71.

[0048] The first elastic component 76 is used to support the piston plate 75, and is located at the upper side when the contact plate 77 is squeezed;

[0049] The movable limiting device 9 includes a fixed shaft 91 fixedly connected under the side support plate 1, a first linear bearing 92 is provided on the outer sleeve of the fixed shaft 91, a movable seat 93 is provided outside the first linear bearing 92, a contact rod 94 is connected to the side of the movable seat 93, and the other end of the contact rod 94 is arranged under the connecting angle plate 3.

[0050] The bottom end of the fixed shaft 91 is fixedly connected with a first limit plate 96, and the outer sleeve of the fixed shaft 91 is provided with a second elastic component 95. The two ends of the second elastic component 95 are respectively fixedly connected with the side support plate 1 and the movable seat 93. The side of the movable seat 93 is connected with an intermediate rod 97, and the other end of the intermediate rod 97 is connected with a movable baffle 98. The movable baffle 98 is arranged parallel to the side support plate 1.

[0051] The fixed shaft 91 cooperates with the first linear bearing 92 to prevent the movable seat 93 and the movable baffle 98 from rotating and shaking during the up and down movement. The second elastic component 95 ensures that the movable baffle 98 is in contact with the rotating connection device 10 on the upper side when not being squeezed from above.

[0052] The rotating connection device 10 includes a pin shaft 101 connected under the side support plate 1, a rotating rod 102 is hinged outside the pin shaft 101, a circular plate 103 is fixedly connected outside the pin shaft 101, a coil spring 104 is arranged outside the pin shaft 101, and the two ends of the coil spring 104 are respectively fixedly connected to the rotating rod 102 and the circular plate 103, and the rotating rod 102 is connected to a sliding connection component 105 arranged under the main support plate 2.

[0053] The movable baffle 98 cooperates with the rotating rod 102. When the movable baffle 98 contacts the rotating rod 102, it blocks the rotating rod 102 and cooperates with the torsion of the coil spring 104 to keep the rotating rod 102 directly below the side support plate 1.

[0054] After the rotating rod 102 loses its resistance, the torsion force of the coil spring 104 controls the rotating rod 102 and the sliding plate 1051 to rotate;

[0055] The sliding connection assembly 105 includes a sliding plate 1051 and a pad 1052 and a limiting column 1053 fixedly connected under the positive support plate 2. A guide sleeve 1054 is connected through the sliding plate 1051. A guide rod 1055 is slidably connected in the guide sleeve 1054. The top end of the guide rod 1055 is connected to the rotating rod 102. The bottom end of the guide rod 1055 is connected to the second limiting plate 1056. The outer sleeve of the guide rod 1055 is provided with a third elastic assembly 1057.

A limiting hole 1058 is provided on the sliding plate 1051, and the limiting column 1053 is slidably arranged in the limiting hole 1058.

[0056] When the sliding plate 1051 rotates to a position close to the positive support plate 2, it will be squeezed by the inclined surface of the pad 1052 and move downward. The sliding plate 1051 and the guide sleeve 1054 slide downward along the guide rod 1055. When the sliding plate 1051 passes over the pad 1052, the sliding plate 1051 is controlled to move upward by the elastic force of the third elastic component 1057, and the limiting column 1053 is inserted into the limiting hole 1058, so that the side support plate 1 and the positive support plate 2 are pulled and connected through the rotating rod 102 and the sliding plate 1051.

[0057] The guide rod 1055 and the guide sleeve 1054 are used to make the sliding plate 1051 slide in the vertical direction when it is subjected to vertical pressure.

[0058] The mobile clamping device 11 includes a movable clamp 111 and a second linear bearing 115 fixedly connected to the positive support plate 2. A connecting groove 112 is opened in the movable clamp 111, and the wire 13 is located in the connecting groove 112. A cross bar 113 is slidably arranged in the second linear bearing 115. The cross bar 113 is fixedly connected to the movable clamp 111. The other end of the cross bar 113 is connected to a third limiting plate 114. The outer sleeve of the cross bar 113 is provided with a fourth elastic component 116 fixedly connected to the movable clamp 111 and the second linear bearing 115. A blocking block 117 is provided on the side of the movable clamp 111. An elastic telescopic rod 118 is fixedly connected to the blocking block 117. The elastic telescopic rod 118 is fixedly connected to the positive support plate 2. The third limiting plate 114 has the same magnetism as the side close to the sliding plate 1051.

[0059] The movable clamps 111 are close to each other and are used to clamp and position the wire 13;

[0060] The sliding plate 1051 will gradually move closer to the third limiting plate 114 during the rotation process, and the magnetic repulsion between the two will squeeze the cross bar 113 and the movable clamp 111 to move closer to the wire 13;

[0061] When the movable clamp 111 moves to a position misaligned with the block 181 and the blocking block 117, the elastic force of the elastic telescopic rod 118 controls the block 181 to move downward and block the movable clamp 111;

[0062] The movable clamping device 18 includes a clamping block 181 slidably connected in the limiting groove 16, and a supporting telescopic rod 182 is fixedly connected to one side of the clamping block 181. The supporting telescopic rod 182 is fixedly connected in the supporting groove 17, and the outer sleeve of the supporting telescopic rod 182 is provided with a fifth elastic component 183 fixedly connected to the clamping block 181 and the supporting groove 17.

[0063] When the sliding seat 14 moves to the bottom end of the slide slot 15, the position of the limit slot 16 corresponds to the block 181, and the elastic force of the fifth elastic component 183 controls the support telescopic rod 182 to automatically extend and control the block 181 to move into the slot;

[0064] A photovoltaic assembly comprises a photovoltaic laminate 6, a connector 121 and a frame structure, wherein the frame structure is installed on the outer side of the photovoltaic laminate 6.

[0065] Working principle, when using:

[0066] Directly place the two side support plates 1 and the two main support plates 2 on the four sides of the photovoltaic laminate 6, and then insert the sliding seat 14 on the connecting angle plate 3 into the corresponding slide groove 15 downward. At this time, the sliding seat 14 moves downward to squeeze the card block 181 to move into the support groove 17. When the sliding seat 14 moves to the bottom end of the slide groove 15, the position of the limit groove 16 corresponds to the card block 181. The elastic force of the fifth elastic component 183 controls the support telescopic rod 182 to automatically extend and control the card block 181 to move into the card groove, completing the assembly between the connecting angle plate 3 and the adjacent side support plates 1 and the main support plate 2. When the connecting angle plate 3 drives the pressure rod 72 to move downward, it squeezes the contact rod 94 to move. When the pressure rod 72 moves downward, it squeezes the contact plate 77 and the piston plate 75 to move downward.

[0067] When the piston plate 75 moves downward, it squeezes the gas in the lower half of the piston frame 71, and the gas is transferred to the stabilizing airbag 5 through the air pipe 8. The stabilizing airbag 5 expands to fill and squeeze the photovoltaic laminate 6 between the positive support plate 2 and the side support plate 1. When the contact rod 94 moves downward, the first linear bearing 92 and the moving baffle 98 are controlled to move downward through the moving seat 93. When the moving baffle 98 moves to separate from the rotating rod 102, the coil spring 104 uses the torque to control the rotating rod 102 and the sliding plate 105 around the pin 1 01 rotates, when the sliding plate 1051 rotates to a position close to the positive supporting plate 2, it will be squeezed downward by the inclined surface of the pad 1052, and the sliding plate 1051 and the guide sleeve 1054 slide downward along the guide rod 1055. When the sliding plate 1051 passes over the pad 1052, the sliding plate 1051 is controlled to move upward by the elastic force of the third elastic component 1057, and the limiting column 1053 is inserted into the limiting hole 1058. At this time, the traction limit between the side supporting plate 1 and the positive supporting plate 2 is completed, so that the stability between the two is increased;

[0068] During the rotation of the sliding plate 1051, it will gradually move closer to the third limit plate 114. The magnetic repulsion between the two will squeeze the cross bar 113 and the movable clamp 111 to move closer to the wire 13. The two movable clamps 111 approach each other and complete the clamping and positioning of the wire 13. When the movable clamp 111 moves to be misaligned with the blocking block 181 and the blocking block 117, the elastic force of the elastic telescopic rod 118 will control the blocking block 181 to move downward and block the movable clamp 111.

[0069] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
