Description

Technical Field

[0001] The utility model relates to an adjustable photovoltaic panel pressing block component, which is applied to the field of photovoltaic battery panel installation. Background Art

[0002] Photovoltaic panels are devices composed of multiple solar cells combined in a specific layout, which are usually fixed to the rails by clamping fittings. These clamping fittings used to connect solar panels are specially customized for the specific height of the module aluminum frame, which limits their application range and leads to high production costs. In order to solve the problems of these traditional medium-voltage fittings, adjustable solar panel clamping assemblies have been developed on the market. This new type of clamping assembly is more flexible in design and can adapt to different heights of module aluminum frames, thereby expanding its application range and helping to reduce production costs.

[0003] Existing photovoltaic panel block assemblies, for example, an adjustable solar panel medium-voltage assembly with application number CN201920853246.1, include a clamping block arranged on a support guide rail, and a clamping block fixed on the clamping block by bolts for fixing the photovoltaic panel. The structural design of the clamping block and the clamping block can further enhance the overall stability. Since the middle through hole of the clamping block is fixed to the bolt by tapping, a certain degree of positioning of the clamping block and the bolt is achieved. However, during use or disassembly, there may be poor matching accuracy between the tapping threads on the clamping block and the bolts, resulting in jamming, thereby affecting the efficiency of assembly or disassembly. In order to solve the above problems, the utility model designs an adjustable photovoltaic panel block assembly. Utility Model Content

[0004] The utility model provides an adjustable photovoltaic panel pressing block assembly, which can effectively solve the above problems.

[0005] The utility model is achieved in this way:

[0006] An adjustable photovoltaic panel pressing block assembly, comprising:

[0007] A clamping block is clamped on the corresponding support rail, and a threaded hole is provided at the center of the top of the clamping block;

[0008] A pressing block, comprising a pressing block body, at least one side of which is provided with a limiting convex edge, and a smooth through hole is provided at the center of the pressing block;

[0009] The locking structure includes a locking bolt for fastening the clamping block and the pressing block, and a spring arranged between the clamping block and the pressing block and sleeved on the locking bolt. The locking bolt passes through the smooth through hole, is threadedly connected to the threaded hole and squeezes the spring, so that the limiting flange and the supporting guide rail are pressed relative to each other, thereby fixing the photovoltaic panel arranged between the limiting flange and the supporting guide rail.

[0010] As a further improvement, the card block includes a card block body, both ends of the card block body are provided with fixed support feet symmetrical about the center line of the card block body, the side wall of the fixed support foot is provided with a card strip, a card slot is formed between the fixed support foot and the card strip, and the card block is connected by the card slot and slidably arranged on the support guide rail.

[0011] As a further improvement, the inner side of the fixed support leg is connected with a top support rib, and the locking bolt passes through between the top support ribs and spreads the top support ribs toward the two inner side surfaces of the guide rail.

[0012] As a further improvement, the card block includes a card block body, and both ends of the card block body are provided with fixed support feet symmetrical about the center line of the card block body, and the side wall of the fixed support foot away from one end of the card block body is provided with a bent portion bent inward, and a slot is formed on the outside of the bent portion, and the card block is engaged and slidably arranged on the support guide rail through the slot.

[0013] As a further improvement, a serrated groove is provided on both sides of the fixed support leg.

[0014] As a further improvement, the pressure block includes a limiting protrusion and a limiting groove arranged on both sides of the pressure block body, the limiting protrusion is connected to both sides of the limiting groove, and a yielding groove is provided on the top of the pressure block body, and the connection between the notch of the yielding groove and the limiting protrusion is arranged in a circular arc transition.

[0015] As a further improvement, a mounting hole is provided on the lower end surface of the limiting protrusion, and a grounding pin shaft is provided in the mounting hole.

[0016] As a further improvement, anti-slip teeth are provided on one side of the limiting protrusion close to the clamping block.

[0017] As a further improvement, the depth of the clearance groove is less than or equal to half of the height of the nut of the locking bolt, and greater than or equal to one quarter of the height of the nut of the locking bolt.

[0018] As a further improvement, the spring is a variable diameter spring, the end of the variable diameter spring with a smaller diameter abuts against the lower end surface of the pressure block, and the end of the variable diameter spring with a larger diameter abuts against the upper end surface of the clamping block.

[0019] The beneficial effects of the utility model are:

[0020] (1) The locking bolt passes through the smooth through hole, is threadedly connected to the threaded hole and squeezes the spring, so that the limiting convex edge and the supporting guide rail move relative to each other, thereby fixing the photovoltaic panel. This can prevent the locking bolt and the pressure block from getting stuck. Under the limiting effect of the spring, before installation, the spring is such that there is a certain distance between the pressure block and the jamming block, which makes it easier to put the photovoltaic panel between the limiting convex edge and the supporting guide rail. This makes installation more convenient, reduces the process of tapping the pressure block, and uses standard springs instead, which reduces costs.

[0021] (2) The inner side of the fixed support leg is connected with a top support rib, and the locking bolt passes through the top support ribs and pushes the top support ribs toward the two inner sides of the guide rail. The locking bolt can not only realize the relative pressing of the pressure block and the clamping block, but also realize the pushing of the fixed support leg to both sides, thereby further improving the installation stability of the clamping block.

[0022] (3) A bent portion bent inwardly is provided on the side wall of one end of the fixed support leg away from the block body, and a slot is formed on the outer side of the bent portion. The block is clamped and slidably arranged on the support rail through the slot. The one-piece bent portion on the fixed support leg can not only realize the stable clamping of the block, but also can realize the purpose of spreading the fixed support leg on both sides by passing the locking bolt between the inner sides of the two bent portions, thereby improving the installation stability of the block. This manufacturing method is simpler, improves production efficiency and saves costs.

[0023] (4) The spring is a variable diameter spring, the end of the variable diameter spring with a smaller diameter abuts against the lower end surface of the pressure block, and the end of the variable diameter spring with a smaller diameter abuts against the upper end surface of the clamping block. By setting the variable diameter spring, the stress distribution of the spring is more uniform due to the change in diameter, which helps to improve the bearing capacity and life of the spring, and makes the end of the variable diameter spring with a smaller diameter abut against the upper end surface of the clamping block, which can effectively fix the spring.

[0040] Reference Figures 1-2 As shown, an adjustable photovoltaic panel clamp assembly includes a clamping block 10, which is clamped on a corresponding support rail 40. The clamping block 10 includes a clamping block body 11, and both ends of the clamping block body 11 are provided with fixed legs 111 symmetrical about the center line of the clamping block body 11. The side wall of the fixed leg 111 is provided with a clamping strip 112, and a clamping groove is formed between the fixed leg 111 and the clamping strip 112. The clamping block 10 is clamped and slidably arranged on the support rail 40 through the clamping groove. The inner side of the fixed leg 111 is connected to a top support rib 113, and the locking bolt 31 passes between the top support rib 113 and opens the top support rib 113 toward the two inner sides of the rail. A threaded hole 116 is provided at the top center of the clamping block 10.

[0041] The pressure block 20 includes a pressure block body 21, and at least one side of the pressure block body 21 is provided with a limiting convex edge 211.

A serrated groove 115 is provided on both sides of the fixed leg 111.

[0048] The limiting slot 213 is replaced with a smooth extended protrusion 216. Compared with the limiting slot 213 in the first embodiment, the extended protrusion 216 is extended downward. When installed in place, the extended protrusion 216 can extend to abut the two ends of the block 10, which can better limit the torsion of the block 10 and improve the installation stability of the pressure block assembly.
