Description

[Technical field]

[0001] The utility model relates to the photovoltaic field, in particular to a corner side pressure block and a side pressure component thereof. [Background technology]

[0002] Solar photovoltaic power generation system is a new type of power generation system that uses the photovoltaic effect of photovoltaic panels to convert solar radiation into electrical energy. Photovoltaic panels are mainly made of semiconductor materials. Existing photovoltaic panels mainly use bolts to lock side pressure components, which are fixed by pressing the photovoltaic panels. However, for photovoltaic panels of different thicknesses and sizes, different types of side pressure components need to be replaced. This method of replacing side pressure components is cumbersome and increases labor costs.

[0003] Reference Figure 1 As shown, in the prior art, the photovoltaic panel 200 is installed on the guide rail 300, and the existing side pressure assembly 100' is used to fix the frame of the photovoltaic panel 200 to prevent the photovoltaic panel 200 from moving. Since the frame of the photovoltaic panel 200 usually has two thickness specifications of 30mm and 35mm, the existing side pressure assembly 100' has two pressure plates adapted to different thickness specifications; when the existing side pressure assembly 100' faces photovoltaic panels 200 adapted to different frame thicknesses, it is necessary to remove its bolts to switch to pressure plates of different lengths, which leads to the following technical problems:

[0004] 1. Removing bolts is time-consuming and laborious, and small parts may be missed or installed upside down, affecting installation efficiency and being unfriendly to installation staff;

[0005] 2. The first pressing plate 101 ′ and the second pressing plate 102 ′ are respectively provided with through holes for bolts to pass through, and the function of replacing the photovoltaic panel 200 to match the specifications cannot be achieved without removing the bolts, and the replacement efficiency is low.

[0006] In view of this, the inventor of this case conducted in-depth research on the above-mentioned issues, which led to the emergence of this case. [Contents of the utility model]

[0007] The utility model provides a corner side pressure block and a side pressure assembly thereof. The corner side pressure block is formed with a strip hole structure, which connects a first through hole and a second through hole while ensuring strength, thereby realizing the convenience of switching the side pressure assembly.

[0008] The utility model is implemented as follows: a corner side pressure block includes a first pressure plate and a second pressure plate fixedly connected; a first through hole for installing bolts is formed at the center of the first pressure plate toward the direction of the second pressure plate, and a second through hole for installing bolts is formed at the center of the second pressure plate toward the direction of the first pressure plate, and the first through hole and the second through hole are connected.

[0009] Furthermore, a first notch is formed on the upper surface of the first pressure plate, and a first limiting surface and a second limiting surface are formed on both sides of the first notch; a second notch is formed on the upper surface of the second pressure plate, and a third limiting surface and a fourth limiting surface are formed on both sides of the second notch.

[0010] Furthermore, the cross-sectional length of the first pressing plate is greater than the cross-sectional length of the second pressing plate.

[0011] Furthermore, the outer surface of the connection between the first pressing plate and the second pressing plate is a curved surface.

[0012] Furthermore, the inner surfaces of the first pressing plate and the second pressing plate are both formed with wave patterns.

[0013] Furthermore, a first stop block is provided on the inner surface of the first pressing plate, and a second stop block is provided on the inner surface of the second pressing plate.

[0014] Furthermore, it also includes a clamping block, a spring and a bolt; a screw hole is formed on the top of the clamping block; the spring is assembled between the top of the clamping block and the inner surface of the corner side pressure block; the bolt passes through the first through hole or the second through hole and then passes through the spring and the screw hole in sequence to connect the corner side pressure block and the clamping block together.

[0015] Furthermore, it also includes a spring washer and a flat washer, and the spring washer and the flat washer are assembled in the first slot or the second slot.

[0016] Furthermore, the card block is a card block with several characters.

[0017] Furthermore, the bolt is any one of a hexagon socket bolt, an external hexagon socket bolt, and a hexagon socket head bolt.

[0018] The advantages of the utility model are:

[0019] 1. The corner side pressure block is designed to be connected with the first through hole and the second through hole while ensuring its strength, so that the corner side pressure block can be switched conveniently. Two pressure plates of different lengths can be switched by rotating the corner side pressure block, and replacement can be achieved without removing the bolts, which saves time and effort and is highly convenient. In addition, small parts will not be missed or installed upside down, which greatly improves the installation efficiency.

[0020] 2. The side pressure assembly uses the force generated by the compression deformation of the spring to prop open the corner side pressure block and the clamping block. Before the bolt is tightened, the spring raises the corner side pressure block to facilitate the insertion of the photovoltaic panel between the corner side pressure block and the guide rail, which facilitates the subsequent locking steps.

[0021] 3. When the side pressure assembly is pressed into the guide rail, the corner side pressure block is too close to the guide rail under the action of gravity, and it is necessary to hold the corner side pressure block by hand to prevent interference with the card block being inserted into the guide rail; therefore, the spring can push the corner side pressure block upward to avoid installation interference.

[0032] Embodiment 1

[0033] See also Figure 2 and 3 As shown, this embodiment provides a corner side pressure block 10, including a first pressure plate 1 and a second pressure plate 2 fixedly connected; a first through hole 11 for installing a bolt 40 is formed at the center of the first pressure plate 1 toward the direction of the second pressure plate 2, and a second through hole 21 for installing the bolt 40 is formed at the center of the second pressure plate 2 toward the direction of the first pressure plate 1, and the first through hole 11 and the second through hole 21 are connected to form a strip hole.

[0034] The corner side pressing block 10 is made of aluminum and is manufactured by an aluminum extrusion process. A long aluminum profile is first extruded, then cut into corner side pressing blocks 10 of required specifications, and finally strip holes are processed on the corner side pressing blocks 10.

[0035] The corner side pressure block 10 of this embodiment ensures strength by designing the first through hole 11 and the second through hole 21 to be connected, so as to realize the convenience of switching the corner side pressure block 10; by rotating the corner side pressure block 10, two pressure plates of different lengths can be switched without removing the bolts 40, which saves time and effort and is highly convenient; and small parts will not be missed or installed upside down, which greatly improves the installation efficiency.

The design of the first limiting surface 13 and the third limiting surface 23 can prevent the bolt 40 from moving outward; the design of the second limiting surface 14 and the fourth limiting surface 24 can prevent the bolt 40 from moving inward; the design of the first limiting groove and the second limiting groove can provide space for the bolt 40, the spring washer 50, and the flat washer 60 to be placed, and at the same time limit the flat washer 60 to prevent the bolt 40 from loosening.

[0037] In this embodiment, the cross-sectional length of the first pressing plate 1 is greater than the cross-sectional length of the second pressing plate 2. The corner side pressing block 10 formed by the first pressing plate 1 and the second pressing plate 2 is L-shaped and can be applied to photovoltaic panels 200 of different thicknesses.

[0038] In this embodiment, the outer surface of the connection between the first pressing plate 1 and the second pressing plate 2 is an arc surface, so that when the corner side pressing block 10 rotates, the spring washer 50 and the flat washer 60 can slide smoothly on the outer surface of the corner side pressing block 10.

[0039] In this embodiment, the inner surfaces of the first pressing plate 1 and the second pressing plate 2 are both formed with corrugations to increase the friction between the corner side pressing block 10 and the photovoltaic panel 200 , thereby ensuring that the corner side pressing block 10 can be tightly attached to the photovoltaic panel 200 .

[0040] In this embodiment, a first stopper 15 is provided on the inner surface of the first pressing plate 1, and a second stopper 25 is provided on the inner surface of the second pressing plate 2. The first stopper 15 and the second stopper 25 are stoppers, which play a role of limiting during installation. The first stopper 15 or the second stopper 25 is in close contact with the photovoltaic panel 200 during installation.

[0041] Embodiment 2

[0042] The photovoltaic panel 200 is installed above the guide rail 300, and the guide rail 300 is used to support the photovoltaic panel 200 away from the roof; the side pressure assembly 100 presses the frame of the photovoltaic panel 200 onto the guide rail 300 from the frame to play a fixing role; the upper part of the guide rail 300 is provided with a groove 301 for cooperating and fixing with the side pressure assembly 100, and the block 20 of the side pressure assembly 100 is inserted into the groove 301 to connect the side pressure assembly 100 and the guide rail 300.

[0043] See also Figure 4-6 As shown, this embodiment provides a side pressure assembly 100, which includes a corner side pressure block 10, a clamping block 20, a spring 30 and a bolt 40; the substantial structure of the corner side pressure block 10 is shown in the first embodiment, and a screw hole 201 is formed on the top of the clamping block 20; the spring 30 is assembled between the top of the clamping block 20 and the inner surface of the corner side pressure block 10; the bolt 40 passes through the first through hole 11 or the second through hole 21 and then passes through the spring 30 and the screw hole 201 in sequence to connect the corner side pressure block 10 and the clamping block 20 together. The clamping block 20 is made of aluminum.

[0044] The side pressure assembly 100 of this embodiment has the following beneficial technical effects:

[0045] 1. The side pressure assembly 100 is applicable to photovoltaic panels with two thickness specifications of 30mm and 35mm. When adjusting and adapting the photovoltaic panels 200 with different frame thicknesses, two pressure plates of different lengths can be switched by rotating the corner side pressure block 10. Replacement can be achieved without removing the bolts 40, which saves time and effort and is highly convenient. In addition, small parts will not be missed or installed upside down, which greatly improves the installation efficiency.

[0046] 2. Use the force generated by the compression deformation of the spring 30 to push open the corner side pressure block 10 and the clamping block 20. Before the bolt 40 is tightened, the spring 30 raises the corner side pressure block 10 to facilitate the insertion of the photovoltaic panel 200 between the corner side pressure block 10 and the guide rail 300, thereby facilitating the subsequent locking steps.

[0047] 3. When the side pressure assembly 100 is pressed into the guide rail 300, the corner side pressure block 10 is too close to the guide rail 300 under the action of gravity, and it is necessary to hold the corner side pressure block 10 by hand to prevent interference with the clamping block 20 being clamped into the guide rail 300; therefore, the spring 30 can push the corner side pressure block 10 upward to avoid installation interference.

[0048] In this embodiment, the side pressure assembly 100 further includes a spring washer 50 and a flat washer 60, which are made of stainless steel. The spring washer 50 and the flat washer 60 are assembled in the first notch 12 or the second notch 22.

The spring washer 50 is provided to prevent the bolt 40 from loosening. The flat washer 60 is provided to disperse the pressure.

[0049] In this embodiment, the clamping block 20 is a ""-shaped" clamping block, including a connecting block and two first and second clamping legs respectively fixed on both sides of the connecting block; the screw hole 201 is formed at the center of the connecting block, and the bottoms of the first and second clamping legs are formed with clamping grooves and clamping hooks that are clamped into the notches 301; the inner wall of the first clamping leg is vertically fixed with a first push piece, and the inner wall of the second clamping leg is vertically fixed with a second push piece, and the first and second push pieces are arranged opposite to each other. The first push piece and the second push piece are used to limit and fix the bottom of the bolt 40.

[0050] In this embodiment, the bolt 40 is any one of a hexagon socket bolt 40 , an outer hexagon socket bolt 40 , and a hexagon socket head bolt 40 .

[0051] Reference Figure 6 In this case, the second pressing plate 2 is pressing the photovoltaic panel 200 with a thickness of 35 mm, and the bolt 40 is screwed on the second through hole 21. When the photovoltaic panel 200 with a thickness of 30 mm needs to be replaced, the first pressing plate 1 is adjusted to press the photovoltaic panel 200, and the steps of adjusting the side pressure assembly 100 are as follows:

[0052] Step 1: Loosen the bolt 40 upward, the corner side pressing block 10 rises, and the photovoltaic panel 200 is taken out;

[0053] Step 2: After the corner side pressing block 10 is horizontally rotated 180°, the corner side pressing block 10 is further rotated 90° clockwise, and the bolt 40 slides along the strip hole from the second through hole 21 to the first through hole 11, and at this time, the first pressing plate 1 faces upward;

[0054] Step 3: Put in the photovoltaic panel 200 with a thickness of 30 mm, tighten the bolts 40 downwards, so that the first pressing plate 1 presses the photovoltaic panel 200, and the replacement of the photovoltaic panel 200 is completed.
