[0002] Solar photovoltaic power generation technology is a technology that uses the photovoltaic effect of semiconductor devices to convert sunlight into electrical energy. The smallest photovoltaic power generation unit is called a solar panel, which is connected in series and parallel, packaged structurally, and electrically connected to form a solar device. The power generation efficiency of a solar panel is negatively correlated with its operating temperature, that is, the higher the temperature, the lower the efficiency.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0030] See also Figure 1-2 In this embodiment, a connector for a photovoltaic bracket includes a mounting rod body 1, and a fastening nut 2 is threadedly connected to the outer surface of the mounting rod body 1. By opening a mounting hole at the top of the roof, the mounting rod body 1 can be fixed to the inside of the mounting hole through the fastening nut 2, and a rubber part 3 is fixed to the lower end of the fastening nut 2. The outer surface of the mounting rod body 1 is provided with a connecting component for connecting to a solar photovoltaic panel.

[0031] Secondly, a through hole is opened at the top of the rubber component 3 so that the rubber component 3 can move up and down on the outer surface of the mounting rod body 1, so that the fastening nut 2 can drive the rubber component 3 to move on the outer surface of the mounting rod body 1, so that the rubber component 3 can abut against the mounting hole at the top of the roof, thereby preventing water leakage along with the roof and also playing a buffering role.

[0032] See also Figure 1 , Figure 3 and Figure 4 The connecting assembly in this embodiment includes a first limiting nut 41, a second limiting nut 42, a connecting plate 43, abutment plate 46, a connecting plate 44, an insert block 45 fixedly mounted on the top of the connecting plate 44, and an adjustment assembly fixedly mounted in the inner cavity of the connecting plate 43, and the connecting plate 43 abuts against the lower end of the abutment plate 46.

[0033] It is also noted that the mounting beam is usually I-shaped, so the insert block 45 is T-shaped so that the insert block 45 can be inserted into the inner side of the mounting beam, so that the mounting beam can be stably located on the top of the connecting plate 43.

[0034] Among them, the first limiting nut 41 and the second limiting nut 42 are both threadedly connected to the outer surface of the mounting rod body 1, so that the first limiting nut 41 and the second limiting nut 42 can move on the outer surface of the mounting rod body 1, so that the first limiting nut 41 and the second limiting nut 42 can fix the connecting plate 43 and the abutment plate 46 therebetween, thereby fixing the connecting plate 43 and the abutment plate 46 to the outer surface of the mounting rod body 1.

[0035] At the same time, through holes are opened at the upper and lower ends of the connecting plate 43, and the mounting rod body 1 is slidably connected to the inner side of the through holes, so that the mounting rod body 1 can pass through the interior of the connecting plate 43 through the two through holes, so that the connecting plate 43 can slide on the outer surface of the mounting rod body 1.

[0036] Moreover, a connecting hole is opened at the top of the butt plate 46, and the mounting rod body 1 is slidably connected to the inner side of the connecting hole, so that the mounting rod body 1 can pass through the inside of the butt plate 46 through the connecting hole, that is, the butt plate 46 can slide on the outer surface of the mounting rod body 1.

[0037] See also Figure 3-4 The adjustment assembly in this embodiment includes two horizontal plates 47, two vertical plates 410, sliders 48 fixedly installed at the upper and lower ends of the horizontal plates 47, a pressure plate 49 fixedly installed at the opposite sides of the front and rear horizontal plates 47, and three support rods 411 fixedly installed at the opposite sides of the left and right vertical plates 410, and the outer surfaces of the three support rods 411 are all sleeved with springs 412.

[0038] Secondly, the connecting plate 43 is a rectangle with a hollow interior and a missing left side. Two transverse plates 47 are slidably connected to the interior of the connecting plate 43 so that the two transverse plates 47 can move in or out of the interior of the connecting plate 43, and the left ends of the two transverse plates 47 are fixed to the right side of the connecting plate 44, so that the distance between the connecting plate 44 and the connecting plate 43 can be adjusted, and can be adjusted according to the width of the mounting beam.

[0039] In addition, the two vertical plates 410 are fixed to the inner cavity of the connecting plate 43, and the three support rods 411 can be firmly located inside the connecting plate 43 through the two vertical plates 410. Three circular holes are opened on the left side of the pressure plate 49, and the support rods 411 are slidably connected to the inner sides of the circular holes, so that the pressure plate 49 can slide on the outer surfaces of the three support rods 411, so that the pressure plate 49 can squeeze the three springs 412, so that the three springs 412 can play an elastic reset and resistance role on the pressure plate 49.

[0040] In addition, two sliding grooves are provided on the upper and lower walls of the inner cavity of the connecting plate 43, and the slider 48 is slidably connected to the inner side of the sliding groove, so that the slider 48 passes through the interior of the connecting plate 43 through the sliding groove, thereby allowing the cross plate 47 to move smoothly inside the connecting plate 43 and preventing the two cross plates 47 from falling off from the inside of the connecting plate 43.

[0041] The working principle of the above embodiment is:

[0042] When in use, when it is necessary to install the solar photovoltaic panel, the rubber member 3, the fastening nut 2, the first limiting nut 41, the connecting plate 43, the abutment plate 46 and the second limiting nut 42 are sequentially sleeved on the outer surface of the mounting rod body 1 in advance, and the connecting plate 43 and the abutment plate 46 can be fixed to the outside of the mounting rod body 1 through the first limiting nut 41 and the second limiting nut 42, so that the mounting rod body 1 can be inserted into the mounting hole previously opened on the top of the roof, and the fastening nut 2 can be rotated to fix the mounting rod body 1 on the top of the roof, so that the rubber member 3 can prevent water leakage and buffer the mounting hole on the top of the roof, so that the mounting beam can be placed on the top of the connecting plate 44 and the connecting plate 43, so that the plug 45 can be plugged into the inner side of the lower end of the mounting beam, and the left side of the abutment plate 46 is abutted against the right side of the mounting beam, so that the mounting beam can be stably placed on the top of the connecting plate 43 and the connecting plate 44, which can effectively improve the installation efficiency of the solar photovoltaic panel, thereby eliminating the need to install a photovoltaic support on the top of the roof, which can effectively improve the convenience of installation;

[0043] Among them, the distance between the connecting plate 44 and the connecting plate 43 can be adjusted according to the width of the mounting beam. By pulling the connecting plate 44 to move to the left, the connecting plate 44 drives the pressure plate 49 to move in the inner cavity of the connecting plate 43 through the two cross plates 47, so that the pressure plate 49 can slide on the outer surfaces of the three support rods 411, so that the pressure plate 49 can squeeze the three springs 412, that is, the distance between the connecting plate 44 and the connecting plate 43 can be adjusted according to the diameter of the mounting beam, which can effectively improve the scope of use.
