Description

Technical Field

[0001] This utility model relates to pressure blocks for installing photovoltaic main components, and in particular to pressure blocks used in photovoltaic brackets for photovoltaic installation. Background Technology

[0002] The photovoltaic industry is developing rapidly, and many problems have arisen in the installation of photovoltaic components and purlins. Currently, when installing photovoltaic components in the middle of the purlin, a middle pressure block is generally used to fix two adjacent photovoltaic components. The thickness of the middle pressure block is determined by the thickness of the photovoltaic component. However, the main body size of the middle pressure block currently used is fixed. Therefore, the fixed-size middle pressure block can only be used for photovoltaic components of the same size. Other sizes of photovoltaic components cannot be used interchangeably. For example, to install two adjacent photovoltaic components with a thickness of 30 cm, only a 30 cm middle pressure block can be used; to install two adjacent photovoltaic components with a thickness of 35 cm, only a 35 cm middle pressure block can be used, and so on. If there are photovoltaic components of different thicknesses in the same photovoltaic project, multiple sizes of middle pressure blocks are required. This necessitates preparing multiple models of side pressure blocks during installation, resulting in a wide variety of types. Moreover, during installation, multiple sizes of side pressure blocks need to be classified, located, and matched, making the installation very inconvenient. Utility Model Content

[0003] This invention provides a pressure block in a photovoltaic bracket for photovoltaic installation. It can adjust the moving height of the horizontal pressure plate to adapt to the thickness of the photovoltaic main component to be pressed down, thereby improving the versatility of installation and greatly improving installation efficiency.

[0004] This utility model adopts the following technical solution: a pressure block for a photovoltaic bracket used in photovoltaic installation, comprising a bidirectional pressure block body and an installation and fixing device. The bidirectional pressure block body includes a central lower pressure body, with horizontal pressure plates respectively provided on both sides of the central lower pressure body. The two horizontal pressure plates are symmetrically distributed on both sides of the central lower pressure body, and the two horizontal pressure plates are aligned with the photovoltaic main components on both sides. The installation and fixing device includes a mounting base, the bottom of which is fixedly installed in the mounting groove of the purlin. A locking bolt is installed on the mounting base, and the top of the locking bolt is provided with a locking screw. The locking nut passes through the middle lower pressure body from top to bottom and extends into the mounting base, where it is fixedly connected. A spring is installed between the mounting base and the middle lower pressure body, and the spring is sleeved on the locking nut. Rotating the locking nut clockwise pushes the middle lower pressure body downward and presses down the spring. The two horizontal pressure plates move downward and press down on the photovoltaic main components on both sides. Rotating the locking nut counterclockwise pushes the middle lower pressure body upward and causes the spring to rebound. The two horizontal pressure plates detach from the photovoltaic main components on both sides as the middle lower pressure body rebounds.

[0005] Furthermore, the mounting base is configured as an inverted U-shaped profile. A lower screw hole is provided in the middle of the upper part of the mounting base, through which the lower part of the locking bolt passes. Two upward-sloping angled buckles are provided on both sides of the bottom of the mounting base, and the two angled buckles are symmetrically arranged. A slot is provided on both sides of the mounting groove of the purlin, and the two angled buckles correspond to the two slots respectively. After the bottom of the mounting base is embedded into the mounting groove, the two angled buckles are respectively embedded into the two slots, thereby fixing the bottom of the mounting base in the mounting groove of the purlin.

[0006] Furthermore, the middle lower pressure body is set as an inverted U-shaped profile. The two sides of the middle lower pressure body are extended upward and bent horizontally to form a horizontal pressure plate. The middle of the middle lower pressure body is provided with an upper screw hole, through which the upper part of the locking bolt passes.

[0007] Furthermore, the horizontal pressure plate is set as a wedge-shaped profile, and anti-slip texture is provided on the bottom surface of the horizontal pressure plate.

[0008] This utility model has the following beneficial effects: After adopting the above technical solution, this utility model utilizes the downward movement of the middle pressing body to press down the spring. After the two horizontal pressing plates move downward with the middle pressing body and press down on the photovoltaic main components on both sides, the horizontal pressing plates lock the two photovoltaic main components. Rotating the locking nut in the opposite direction can push the middle pressing body upward and cause the spring to rebound. The two horizontal pressing plates disengage from the photovoltaic main components on both sides as the middle pressing body rebounds. In this way, the descent distance of the horizontal pressing plates can be adjusted according to the required thickness of the photovoltaic main components, without the need to configure a separate pressing device for each model of photovoltaic main component. This effectively enhances the versatility of the tools used when pressing down the photovoltaic main components, greatly saves costs, facilitates the installation of photovoltaic equipment, and improves installation efficiency.

[0012] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0013] exist Figure 1 and Figure 2 This utility model provides a pressure block for photovoltaic (PV) mounting systems, comprising a bidirectional pressure block body 1 and a mounting and fixing device 2. The bidirectional pressure block body 1 includes a central lower pressure body, with horizontal pressure plates 3 symmetrically distributed on both sides of the central lower pressure body. The two horizontal pressure plates 3 are aligned with the PV main components 4 on both sides. The mounting and fixing device includes a mounting base 5, the bottom of which is fixedly installed in the mounting groove 7 of a purlin 6. Locking bolts 8 are installed on the mounting base 5. The top of the locking bolt 8 is equipped with a locking nut 9. The locking bolt 8 passes through the intermediate pressing body from top to bottom and extends into the mounting base 5, where it is fixedly connected. A spring 10 is provided between the mounting base 5 and the intermediate pressing body. The spring 10 is sleeved on the locking bolt 8. Rotating the locking nut 9 clockwise pushes the intermediate pressing body downward and presses down the spring 10. As the intermediate pressing body moves downward, the two horizontal pressure plates 3 press against the photovoltaic main components 4 on both sides. Rotating the locking nut 9 counterclockwise pushes the intermediate pressing body upward. This causes the spring 10 to rebound, and the two horizontal pressure plates 3, along with the rebound of the middle lower pressure body, disengage from the photovoltaic main components 4 on both sides. In this embodiment, the mounting base 5 is designed as an inverted U-shaped profile. A lower screw hole 11 is provided in the middle of the upper part of the mounting base 5, through which the lower part of the locking bolt 8 passes. Two upward-inclined angled buckles 12 are provided on both sides of the bottom of the mounting base 5, symmetrically arranged. Slots are provided on both sides of the mounting groove 7 of the purlin 6, with the two angled buckles 12 corresponding to the two slots. The mounting base 5... After the bottom is embedded into the mounting groove 7, it is embedded into the two slots respectively by two beveled buckles 12, so that the bottom of the mounting base 5 is fixedly installed in the mounting groove 7 of the purlin 6. In this embodiment, the middle pressing body is set as an inverted U-shaped profile. The two sides of the middle pressing body are extended upward and bent horizontally to form a horizontal pressing plate 3. The middle of the middle pressing body is provided with an upper screw hole 13. The upper part of the locking bolt 8 passes through the upper screw hole 13. In this embodiment, the horizontal pressing plate 3 is optimized as a wedge-shaped profile. The bottom surface of the horizontal pressing plate 3 is provided with anti-slip texture 14.

[0014] The method of using this utility model is as follows: Place this utility model between two photovoltaic main components 4, align the two horizontal pressure plates 3 with the photovoltaic main components 4 on both sides, rotate the locking nut 9 in the forward direction, causing the locking nut 9 to move downward and push the middle pressing body downward and press down the spring 10. The middle pressing body drives the horizontal pressure plates 3 on both sides to press down. After the two horizontal pressure plates 3 are pressed down to the height of the two photovoltaic main components 4 with the middle pressing body, tighten the locking nut 9. Under the action of the spring, the two horizontal pressure plates 3 are pressed tightly on the photovoltaic main components 4 on both sides. When it is necessary to release the photovoltaic main components 4 on both sides, rotate the locking nut 9 in the reverse direction. Under the rebound force of the spring 10, push the middle pressing body upward. The two horizontal pressure plates 3 are separated from the photovoltaic main components 4 on both sides as the middle pressing body rebounds, thereby releasing the photovoltaic main components 4 on both sides.

[0015] However, this is not the only possibility. Any variations or substitutions conceived without inventive effort should be included within the scope of protection of this utility model. Therefore, the scope of protection of this utility model should be determined by the scope defined in the claims.
