Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic component installation, in particular to a counterweight base for a photovoltaic bracket. Background Art

[0002] Photovoltaic power generation is a technology that uses the photovoltaic effect of semiconductor interfaces to directly convert light energy into electrical energy. It is mainly composed of three parts: solar panels (modules), controllers and inverters, and the main components are composed of electronic components. After solar cells are connected in series and packaged for protection, they can form large-area solar cell modules, which are then combined with power controllers and other components to form photovoltaic power generation devices.

[0003] With the rapid development of photovoltaic power generation technology, the stability and safety of photovoltaic brackets have received more and more attention. In the photovoltaic power generation system, the photovoltaic bracket is an important part of supporting and fixing photovoltaic components. Its stability and safety directly affect the overall performance and life of the photovoltaic power generation system. Most of the existing photovoltaic brackets use counterweights to fix the bottom, but the counterweights only have the function of increasing weight, resulting in a single effect of the counterweights. After long-term use, the bottom of the photovoltaic bracket will become loose, which indirectly shortens the connection duration between the photovoltaic bracket and the counterweight. For this reason, we propose a new type of counterweight base for photovoltaic brackets. Utility Model Content

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] like Figure 1-Figure 4 As shown, the utility model provides a technical solution: a counterweight base for a photovoltaic bracket, comprising:

[0027] A counterweight body 1, wherein mounting grooves 3 are arranged on the left and right sides of the counterweight body 1, fixing holes 4 are arranged on the front and rear sides of the counterweight body 1, and the fixing holes 4 are used to assist the clamping mechanism 7 for fixing, and a limiting groove 5 is arranged on the top of the counterweight body 1 for installing the photovoltaic bracket, and a slot 2 is arranged in the middle of the front and rear sides of the counterweight body 1, and the slot 2 is used to cooperate with the connecting mechanism 6;

[0028] A connecting mechanism 6 is provided at the front and rear sides of the counterweight body 1 and is used to connect the counterweight bodies 1;

[0029] The clamping mechanism 7 is arranged on the left and right sides of the counterweight body 1 and is used to fix the photovoltaic support.

[0030] The connecting mechanism 6 comprises:

[0031] A fixed plate 604 is installed on the front and rear sides of the counterweight body 1, and an arc plate 602 is rotatably installed between the fixed plates 604. A rotating rod 601 is installed on the inner side of the arc plate 602. Both ends of the rotating rod 601 pass through the fixed plate 604. An insertion rod 603 is installed on one side of the arc plate 602, and the insertion rod 603 is located in the slot 2.

[0032] like Figure 2 As shown, it should be noted that: when using the counterweight block body 1 to fix the photovoltaic bracket, different photovoltaic brackets require different counterweight block bodies 1, and pouring on site is time-consuming and labor-intensive. For this reason, we prefabricate the counterweight block body 1, and stack the counterweight block bodies 1 on each other to increase the counterweight of the photovoltaic bracket. By rotating the arc plate 602, the insertion rod 603 can be driven to swing. The insertion rod 603 can enter the slot 2 during the swinging process, thereby realizing the connection between the counterweight block bodies 1.

[0033] The clamping mechanism 7 comprises:

[0034] A fixing seat 701 is installed on the inner side of the mounting groove 3, and a mounting plate 702 is fixedly connected to the right side of the fixing seat 701. A rotating block 703 is rotatably installed on one side of the mounting plate 702. The rotating block 703 is connected to a threaded rod 708. The threaded rod 708 is rotatably installed on the inner side of the mounting plate 702, and the threaded rod 708 and the fixing seat 701 are located on the same side of the mounting plate 702.

[0035] A fixed sleeve 704 is fixedly connected to one side of the mounting plate 702, a threaded sleeve 705 is threadedly connected to the outer wall of the threaded rod 708, a square plate 706 is fixedly installed at one end of the threaded sleeve 705, a mountain plate 707 is installed on the left side of the square plate 706, a plurality of sliding grooves 712 are arranged on the inner side of the fixed sleeve 704, a plurality of sliding rods 713 are arranged on the outer wall of one end of the threaded sleeve 705, and the sliding rods 713 are located in the sliding grooves 712.

[0036] A plurality of grooves 709 are provided on the square plate 706, and the grooves 709 correspond to the protruding parts of the mountain-shaped plate 707. A fixing rod 710 is movably installed on the inner side of the fixing hole 4, and locking rings 711 are rotatably installed on both ends of the fixing rod 710. The locking ring 711 is located on the outer side of the counterweight block body 1. A fixing hole 4 is also provided on the fixing seat 701, and the fixing rod 710 passes through the fixing seat 701.

[0037] like Figure 3As shown, it should be noted that: when fixing the photovoltaic bracket, placing the vertical plate of the photovoltaic bracket in the limiting groove 5 can facilitate the installation of the photovoltaic bracket, and by installing the fixing seat 701 in the installation groove 3, it is convenient to disassemble the clamping mechanism 7, and by installing locking rings 711 at both ends of the fixing rod 710, the fixing seat 701 can be limited, so that the fixing seat 701 is tilted on the inner side of the counterweight block body 1, and the mountain plate 707 is installed in the groove 709 on the square plate 706, which can facilitate the replacement of the mountain plate 707. The mountain plate 707 is used to assist in fixing the photovoltaic bracket, and the threaded rod 708 can be driven to rotate by rotating the rotating block 703. During the rotation of the threaded rod 708, the threaded sleeve 705 is driven to move forward. During the movement of the threaded sleeve 705, the mountain plate 707 is driven to assist in fixing the photovoltaic bracket. When the mountain plate 707 contacts the photovoltaic bracket, one end of the threaded sleeve 705 is still partially located on the inner side of the fixed sleeve 704. The sliding groove 712 on the inner side of the fixed sleeve 704 limits the movement state of the threaded sleeve 705 during the movement of the threaded sleeve 705 driven by the threaded rod 708, thereby preventing the threaded sleeve 705 from rotating synchronously during the rotation of the threaded rod 708. When the sliding groove 712 limits the sliding rod 713 on the outer wall of the threaded sleeve 705, the threaded sleeve 705 can perform a translation operation.

[0038] The threaded sleeve 705 covers the entire threaded rod 708 . A fixing sleeve 704 is installed on the outer wall of the threaded sleeve 705 near one end of the mounting plate 702 . The outer diameter of the threaded sleeve 705 located inside the fixing sleeve 704 is smaller than that of the threaded sleeve 705 near the square plate 706 .

[0039] To sum up, the counterweight base used in the photovoltaic bracket drives the insertion rod 603 to swing by rotating the arc plate 602. During the swinging process, the insertion rod 603 can enter the slot 2 on another counterweight block body 1, which is convenient for connecting the counterweight block bodies 1, and can fix counterweight block bodies 1 of different weights between different photovoltaics; at the same time, by rotating the rotating block 703, the threaded rod 708 can be driven to rotate, and the threaded rod 708 rotates and drives the threaded sleeve 705 to translate. During the translation of the threaded sleeve 705, the mountain plate 707 is driven to fix the photovoltaic bracket. By setting the fixing rod 710, it is convenient to disassemble the fixing seat 701, thereby improving the practicality of the device.
