Description

Technical Field

[0001] This utility model relates to the field of photovoltaic bracket installation technology, specifically a balancing device for photovoltaic brackets. Background Technology

[0002] Photovoltaic (PV) mounting systems are specialized supports used to place, install, and secure solar panels in a solar photovoltaic (PV) power generation system. These supports are designed to ensure the stable and safe installation of PV modules in various environments, including rooftops, ground surfaces, and water surfaces, to support the stable operation of the PV power plant. PV mounting systems are made from a variety of materials, including aluminum alloy, carbon steel, and stainless steel. Some systems are also hot-dip galvanized to ensure they will not rust for up to 30 years of outdoor use.

[0003] Chinese Patent 202322464441.4 discloses a photovoltaic (PV) bracket balancing device for installation on a PV bracket support. The PV bracket balancing device includes a housing, a tension / pressure plate, an anchor, and an elastic element. The housing extends substantially along a predetermined straight line; the tension / pressure plate is disposed within the housing; the anchor is disposed on the tension / pressure plate for fixing steel cables; the elastic element is at least partially disposed within the housing, with one end connected to the tension / pressure plate and the other end connected to the bottom of the housing. When the anchor is subjected to a force along the predetermined straight line from the steel cables, the anchor drives the tension / pressure plate to move along the predetermined straight line, and causes the elastic element to extend and retract along the predetermined straight line. Through this arrangement, the pull-out force and / or pressure from the steel cables can be balanced, reducing the load on the PV bracket balancing device from the steel cables, thereby improving the stability of the PV bracket balancing device, reducing its operation and maintenance costs, and also improving its safety performance.

[0004] Existing balancing devices for photovoltaic (PV) brackets use a combination of steel cables and elastic elements to level the brackets. However, in many cases, PV brackets are installed in outdoor areas where they frequently encounter extreme weather conditions such as strong winds. The combination of steel cables and elastic elements is not stable enough, and the brackets are prone to swaying in strong winds, affecting the stability of the entire PV bracket and the photovoltaic panels above it. Furthermore, existing devices lack a mechanism for visually observing whether the balance is maintained, and the adjustment process may require the use of a level or other auxiliary measurement, making the operation cumbersome.

[0005] Therefore, a balancing device for photovoltaic brackets is proposed to address the above problems. Utility Model Content

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0029] Example 1

[0030] like Figure 1 As shown, a balancing device for a photovoltaic support includes a main frame 1, an adjustment and leveling component 2 installed at the bottom of the main frame 1, and a fixed component 3 installed at the bottom end of the adjustment and leveling component 2. A balance observation component 4 is installed on the outer wall of the main frame 1, and a photovoltaic support leg 5 is engaged with the top of the main frame 1. The end of the photovoltaic support leg 5 is threaded with a mounting bolt 6. The photovoltaic support leg 5 and the main frame 1 form an engaging structure, and the photovoltaic support leg 5 and the main frame 1 form a detachable structure through the mounting bolt 6.

[0031] like Figure 3 As shown, a balancing device for a photovoltaic support includes a height adjusting nut 201 that forms a rotating structure with a height adjusting cylinder 203 via a rotating retaining ring 202. The height adjusting cylinder 203 forms a lifting structure with a support threaded post 204 via the height adjusting nut 201. A rotating ball bearing 205 forms a rotating structure with the height adjusting nut 201, and the ball bearing 205 is set at an equal angle to the outer wall of the height adjusting nut 201. An insert rod 207 forms a threaded detachable structure with the height adjusting nut 201 via a threaded connector 206. The height of the support leg is adjusted by the interaction of the height adjusting nut 201 and the support threaded post 204. This method is superior to existing methods that use elastic elements for adjustment. This adjustment method ensures the stability of the outriggers, preventing them from swaying even in extreme weather conditions such as strong winds. Detachable insert rods 207 are provided on both sides of the height adjustment nut 201. When adjustment is needed, the insert rods 207 can be attached for rotational adjustment. After adjustment, the insert rods 207 can be removed. The outer wall of the height adjustment nut 201 is equipped with rolling balls 205 to prevent unauthorized personnel from easily rotating the nut. All four outriggers can be height-adjusted, and their coordinated operation allows for leveling of the main frame 1 of the balancing device, enabling it to adapt to different terrain conditions.

[0032] like Figure 2As shown, a balancing device for a photovoltaic bracket is disclosed. The leveling observation cavity 401 is made of transparent acrylic material and is detachable from the main frame 1 of the balancing device via a disassembly and assembly block 404. The leveling mark 403 is parallel to the main frame 1 of the balancing device. The insertion shaft 406 is elastically connected to the disassembly and assembly block 404 via a spring 405. Two insertion shafts 406 are symmetrically arranged about the vertical central axis of the disassembly and assembly block 404. The bayonet 407 is located on the inner wall of the main frame 1 of the balancing device. The colored liquid 402 cooperates with the leveling mark 403, allowing the operator to observe whether the device is level in real time during the leveling process. The structure is simple and easy to operate. After the installation of one balancing device is completed, the balancing observation component 4 can be installed on other balancing observation components 4 for continued use, which helps to save costs.

[0033] like Figure 4 and Figure 5 As shown, a balancing device for a photovoltaic bracket is provided. The cement injection hole 302 is set at an equal angle to the side of the circular base plate 301, and the circular base plate 301 is welded to the supporting threaded column 204. The first anti-detachment block 305 is set at an equal angle to the outside of the first anti-detachment plate 304, and the area of ​​the first anti-detachment plate 304 is smaller than the area of ​​the second anti-detachment plate 306, and the area of ​​the second anti-detachment plate 306 is smaller than the area of ​​the third anti-detachment plate 308. The embedded column 303 is provided with three layers of anti-detachment plates and anti-detachment blocks on its outside, which can increase the contact area between the embedded fixing component 3 and the concrete, thereby enhancing the stability of its fixation after embedding and preventing it from easily detaching from the ground. The area of ​​the three anti-detachment plates gradually increases from top to bottom, with the upper layer having a smaller area, so as not to obstruct the downward flow of concrete.

[0034] Working principle: Before installation, the balance observation component 4 is installed on the outer wall of the main frame 1 of the balance device. The disassembly and assembly plug 404 is inserted into the pre-reserved opening on the outer wall of the main frame 1 of the balance device. At the same time, the insertion clip 406 is squeezed and retracts inward into the disassembly and assembly plug 404. After being inserted into the designated position, the insertion clip 406 is aligned with the corresponding hole and then extends outward after losing the squeezing force, thus locking into the main frame 1 of the balance device to limit and fix the leveling observation cavity 401. By observing whether the liquid level of the colored liquid 402 is flush with the leveling mark 403, it can be determined whether the main frame 1 of the balance device has been adjusted to balance. After the installation of one balance device is completed, the operator can insert his / her finger into the slot 407 and press the insertion clip 406 to remove the balance observation component 4. It can be reused when installing other balance devices.

[0035] This balancing device is installed at the bottom of the photovoltaic bracket. During installation, first dig a corresponding hole at the designated location on the ground, then embed the fixing component 3 into the hole so that the circular base plate 301 is flush with the ground. Then, inject concrete into the bottom of the circular base plate 301, that is, the inside of the hole, through the cement injection hole 302. After the concrete solidifies, the embedded column 303 can be firmly fixed in the ground.

[0036] If the ground where the mounting bracket is installed is uneven and balance adjustment is required, rotate the height adjustment nut 201. Since the height adjustment nut 201 is threadedly connected to the support threaded column 204, when the height adjustment nut 201 is rotated, it can move the height adjustment cylinder 203 up and down, thereby adjusting the height of a certain corner of the main frame 1 of the balancing device. While adjusting, the balance observation component 4 can be observed until the main frame 1 of the balancing device is in a balanced state. After the balancing device is leveled, the bottom end of the photovoltaic bracket support leg 5 can be inserted into the interior of the main frame 1 of the balancing device, and the mounting bolts 6 can be screwed in to fix the two, thus completing the installation of the photovoltaic bracket.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
