Description

Technical Field

[0001] The utility model relates to the field of photovoltaic equipment, in particular to a photovoltaic bracket adaptable to photovoltaic plates of multiple specifications. Background Art

[0002] A photovoltaic power generation system, referred to as PV for short, refers to a power generation system that directly converts solar radiant energy into electrical energy by using the photovoltaic effect of photovoltaic cells. Photovoltaic power generation is a clean, safe and renewable energy source. The photovoltaic power generation process does not pollute the environment or damage the ecology. Photovoltaic equipment generally consists of a photovoltaic panel and a photovoltaic bracket.

[0003] Chinese utility model patent with publication number CN 220775720 U discloses a combined photovoltaic bracket. By opening a clamping groove on the side of a conventional installation bracket, multiple photovoltaic plates can be installed simultaneously, achieving the purpose of saving the installation time of photovoltaic panels and improving the installation efficiency. Although it realizes the purpose of saving the installation time of photovoltaic panels and improving the installation efficiency, when it is necessary to repair and maintain a certain photovoltaic panel, the installation bracket needs to be disassembled. Since one end of multiple photovoltaic plates is supported and fixed by the clamping groove 14 on an installation bracket, during disassembly, the problem of disassembling all the photovoltaic plates on the installation bracket for the repair of one photovoltaic panel often occurs, which not only affects the normal use of photovoltaic panels but also causes waste of labor. There are obvious drawbacks in the subsequent use process of this device.

[0004] Therefore, a photovoltaic bracket adaptable to photovoltaic plates of multiple specifications is provided to solve the above problems. Content of the Utility Model

[0005] The utility model provides a photovoltaic bracket adaptable to photovoltaic plates of multiple specifications, aiming to solve the problem that the existing photovoltaic bracket is inconvenient for repair and maintenance after unified assembly in the background art.

[0006] To achieve the above object, the utility model provides the following technical solution: A photovoltaic bracket adaptable to photovoltaic plates of multiple specifications includes at least two opposing crossbars, two opposing longitudinal bars disposed at the bottom of the crossbars and intersecting the crossbars at a right angle, and a base for supporting the crossbars and the longitudinal bars. The two crossbars are U-shaped steel members, the opening surfaces of the two crossbars are in a side-lying manner and are arranged facing away from each other, and an adjustable installation mechanism is provided on the two crossbars;

[0007] In order to be able to install a large number of photovoltaic panels of different specifications in one installation project and at the same time facilitate the maintenance of the photovoltaic panels during subsequent use, the adjustable installation mechanism includes a chute opened at the bottom of the support crossbar. A screw rod is slidably installed in the chute. One end of the screw rod is fixedly installed with a knob, and the other end of the screw rod extends into the crossbar cavity through the chute and is screwed with a connecting plate. A fixing member for installing the photovoltaic panel is arranged on the connecting plate facing the opening direction of the crossbar. By extending the connecting plate on the screw rod and a part of the screw rod into the chute, and then sliding the screw rod in the chute, the fixing member connected to the connecting plate can be freely adjusted in the chute. Each photovoltaic panel is fixed by two fixing members on each of the two crossbars. Since the position of the screw rod can slide without restriction, it is possible to adapt to the installation of photovoltaic panels of different specifications and sizes. The number of photovoltaic panels to be installed determines the number of corresponding screw rods and fixing members to be installed and adjusted. It can be installed freely in large quantities, which is different from the existing fixed installation frames that need to produce corresponding brackets in different specification batches during production. This photovoltaic bracket that can be adapted to the installation of multi-specification photovoltaic panels can be produced uniformly and applied uniformly. During maintenance, only the corresponding fixing members need to be removed, which saves time and effort, reduces the maintenance difficulty, reduces the transportation difficulty, and improves the efficiency.

[0008] Preferably, in order to stabilize the position of the screw rod after debugging, a top block is fixedly installed on the side of the knob facing the chute, and a washer sleeved on the screw rod is installed on the top of the top block. When the knob is rotated, the top block will push the washer upward, so that the washer is tightly attached to the bottom surface of the crossbar. Through the clamping of the two sides of the connecting plate and the washer, the screw rod is fixed at a specific position adjusted in the chute, and the operation is convenient and fast.

[0009] Preferably, in order to prevent the connecting components in the device from being damaged too quickly by environmental factors such as rain, snow, sand and dust, and sun exposure, the fixing member is an inverted F-shaped steel member fixedly composed of a first horizontal plate, a second horizontal plate and a vertical plate. The first horizontal plate extends into the crossbar cavity through the lateral opening of the crossbar and is assembled with the connecting plate. A docking thread groove for screwing the screw rod is opened on the first horizontal plate. The second horizontal plate and the vertical plate are located outside the crossbar and are provided with installation grooves for assembling the photovoltaic panel. By setting the fixing member as an inverted F-shaped steel member, most of the structure of the adjustable installation mechanism can always be inside the crossbar, and only the second crossbar and the vertical plate for connecting the photovoltaic panel are exposed. This can not only facilitate the normal installation of the photovoltaic panel, but also protect easily damaged parts such as the screw rod and improve the service life of the device.

[0010] Preferably, to facilitate the assembly of the fixing member and the connecting plate, a slot for inserting and assembling the first cross plate is formed at the top of the connecting plate. A stopper for aligning and docking the threaded groove and the screw is fixedly installed at one end of the slot. The first cross plate is aligned with the connecting plate through the slot, which can reduce the installation time and improve the efficiency. The setting of the stopper is to facilitate the alignment of the threaded groove and the screw, preventing the first cross plate from not being inserted in place in the slot and resulting in the inability to dock the screw, which belongs to an anti-fooling setting and is very convenient to operate.

[0011] Preferably, to provide more support for the fixing member and make the installation of the photovoltaic panel more stable, a support strip is fixedly installed at the position where the inner wall of the cross bar cavity near the opening is coplanar with the chute. The height of the support strip is the same as the height of the slot from the bottom of the connecting plate. After the fixing member is installed, the bottom of the first cross plate is supported by both the support strip and the connecting plate, with high reliability.

[0012] Preferably, to enable the device to better adapt to different installation points, the photovoltaic support further includes an adjustable mounting base installed on the top of the base for supporting and fixing the cross bar and the longitudinal bar. The adjustable mounting base includes a connecting seat hinged to the top of the base. A turntable is rotatably installed on the top of the connecting seat. A longitudinal groove for installing the longitudinal bar is fixedly installed on the top of the turntable. A transverse groove for installing the cross bar and arranged at a right angle is fixedly installed on the top of the longitudinal groove. When the installation of the first group of bases is completed, when installing the second group of bases and subsequent bases, if it is not convenient to adjust due to ground factors, without changing the installation position of the first group of bases, the position and orientation of the upper longitudinal groove and transverse groove can be adjusted by rotating the turntable, so as to install the cross bar and the longitudinal bar, without the need to frequently position on the ground at the initial stage of installing the bases, saving working hours and improving efficiency.

[0013] This photovoltaic support can adapt to the installation of photovoltaic panels of different specifications and sizes. The number of corresponding screws and fixing members can be installed and adjusted according to the number of photovoltaic panels to be installed, enabling large-scale free installation. Different from existing fixed mounting frames that require the production of corresponding supports in different specification batches during production, this photovoltaic support for installing photovoltaic panels of multiple specifications can be uniformly produced and uniformly applied. During maintenance, only the corresponding fixing members need to be removed, saving time and effort, reducing the maintenance difficulty, reducing the transportation difficulty, and improving the efficiency.

[0014] For this photovoltaic support, when the installation of the first group of bases is completed, when installing the second group of bases and subsequent bases, without changing the installation position of the first group of bases, the position and orientation of the upper longitudinal groove and transverse groove can be adjusted by rotating the turntable, so as to install the cross bar and the longitudinal bar, without the need to frequently position on the ground at the initial stage of installing the bases, saving working hours and improving efficiency.

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention. Embodiment

[0024] This embodiment provides a photovoltaic bracket adaptable to multiple specifications of photovoltaic plates. As Figure 1-4 shown, this photovoltaic bracket includes at least two opposed cross bars 1, two opposed longitudinal bars 2 disposed at the bottom of the cross bar 1 and intersecting the cross bar 1 at a right angle, and a base 3 for supporting the cross bar 1 and the longitudinal bar 2. The two cross bars 1 are U-shaped steel members, the opening surfaces of the two cross bars 1 are in a side-lying manner and are arranged facing away from each other, and an adjustable mounting mechanism 4 is provided on the two cross bars 1;

[0025] The adjustable mounting mechanism 4 includes a chute 41 opened at the bottom of the support cross bar 1. A screw rod 42 is slidably mounted in the chute 41. One end of the screw rod 42 is fixedly installed with a knob 43. The other end of the screw rod 42 extends into the cavity of the cross bar 1 through the chute 41 and is screwed with a connecting plate 44. A fixing member 45 for installing a photovoltaic panel is arranged on the connecting plate 44 facing the opening direction of the cross bar 1.

[0026] During use, by extending the connecting plate 44 on the screw rod 42 and a part of the screw rod 42 into the chute 41, and then sliding the screw rod 42 in the chute 41, the fixing member 45 connected to the connecting plate 44 can be freely adjusted in the chute 41. Each photovoltaic panel is fixed by two fixing members 45 on each of the two cross bars 1. Since the position sliding of the screw rod 42 is not restricted, it can adapt to the installation of photovoltaic panels of different specifications and sizes. The number of photovoltaic panels to be installed can be determined, and the corresponding screw rods 42 and fixing members 45 can be installed and adjusted accordingly. It can be freely installed in large quantities, which is different from the existing fixed mounting frames that require production of corresponding brackets in different specification batches. This photovoltaic bracket that can be adapted to the installation of multi-specification photovoltaic panels can be produced uniformly and applied uniformly, saving time and effort, reducing the transfer difficulty, and improving the efficiency.

[0027] It should be noted that the diameter of the screw rod 42 is smaller than the slot width of the chute 41. The width of the connecting plate 44 is adapted to the slot width of the chute 41. The length of the connecting plate 44 is greater than the slot width of the chute 41 and less than the inner cavity width of the cross bar 1. The diameters of the top block 431 and the washer 432 are both greater than the slot width of the chute 41, which is convenient for installing the screw rod 42 and positioning the screw rod 42 through the connecting plate 44 and the top block 431.

[0028] Among them, a top block 431 is fixedly installed on the side of the knob 43 facing the chute 41. A washer 432 sleeved on the screw rod 42 is installed on the top of the top block 431. During use, when the knob 43 is rotated, the knob 43 drives the screw rod 42 to rotate upward and rise. The top block 431 will push the washer 432 upward, so that the washer 432 is close to the bottom surface of the cross bar 1. Through the clamping of both sides of the connecting plate 44 and the washer 432, the screw rod 42 is fixed at a specific position adjusted in the chute 41. When it needs to be loosened, the knob 43 is rotated in reverse. The knob 43 drives the screw rod 42 to rotate downward and descend. The top block 431 no longer pushes the washer 432, so that the washer 432 is loosened and separated from the bottom surface of the cross bar 1, and the operation is convenient and fast.

[0029] Specifically, the fixing member 45 is an inverted F-shaped steel member fixedly combined by a first horizontal plate 451, a second horizontal plate 452 and a vertical plate 453. The first horizontal plate 451 extends into the cavity of the cross bar 1 through the lateral opening of the cross bar 1 and is assembled with the connecting plate 44. A docking thread groove 454 for screwing the screw 42 is provided on the first horizontal plate 451. The second horizontal plate 452 and the vertical plate 453 are located outside the cross bar 1 and are provided with mounting grooves 455 for assembling the photovoltaic panel.

[0030] During use, the first horizontal plate 451 is inserted into the cavity of the open end of the cross bar 1 to be docked with the connecting plate 44. The second horizontal plate 452 and the vertical plate 453 are exposed outside the cross bar 1. The second horizontal plate 452 is used to support the bottom of the photovoltaic panel, and the vertical plate 453 is used to enclose the side of the photovoltaic panel. The reserved holes of the photovoltaic panel are fixed through the mounting grooves 455.

[0031] Furthermore, a slot 441 for inserting and assembling the first horizontal plate 451 is provided at the top of the connecting plate 44. A stop block 442 for aligning the docking thread groove 454 and the screw 42 is fixedly installed at one end of the slot 441.

[0032] During use, the first horizontal plate 451 is inserted into the slot 441 until the end of the first horizontal plate 451 abuts against the stop block 442. At this time, rotate the knob 43, and the screw 42 can be rotated upward to be screwed with the docking thread groove 454 to complete the fixation of the first horizontal plate 451 and the connecting plate 44. When disassembling, reverse the knob 43 to make the screw 42 rotate downward to disengage the screw 42 from the docking thread groove 454.

[0033] Even further, a support bar 46 is fixedly installed at the position where the inner wall of the cavity of the cross bar 1 near the opening is coplanar with the sliding groove 41. The height of the support bar 46 is the same as the height of the slot 441 from the bottom of the connecting plate 44. During use, after the fixing member 45 is installed, the bottom of the first horizontal plate 451 slides on the support bar 46 at the same time and is supported by the connecting plate 44. The reliability of the two support points is high. Embodiment

[0034] Different from Embodiment 1, as Figure 1 、 Figure 5 and Figure 6 shown, this photovoltaic bracket further includes an adjustable mounting seat 5 installed on the top of the base 3 for supporting and fixing the cross bar 1 and the longitudinal bar 2. The adjustable mounting seat 5 includes a connecting seat 51 hinged to the top end of the base 3. A turntable 52 is rotatably installed on the top of the connecting seat 51. A longitudinal groove 53 for installing the longitudinal bar 2 is fixedly installed on the top of the turntable 52. A transverse groove 54 which is arranged at a right angle and is used for installing the cross bar 1 is fixedly installed on the top of the longitudinal groove 53.

[0035] In use, after the first set of bases 3 is installed, when installing the second set of bases 3 and subsequent bases 3, without changing the installation position of the first set of bases 3, by rotating the turntable 52, the position and orientation of the upper longitudinal groove 53 and the transverse groove 54 can be adjusted, so as to install the cross bar 1 and the longitudinal bar 2. There is no need to frequently position on the ground at the initial stage of installing the bases 3, saving working hours and improving efficiency.

[0036] The above is only a preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, making equivalent replacements or changes, should be covered within the protection scope of the present utility model.
