Description

Technical Field

[0001] This invention belongs to the field of photovoltaic module technology, and specifically relates to a photovoltaic device. Background Technology

[0002] A photovoltaic (PV) panel is a power generation device that produces direct current (DC) electricity when exposed to sunlight. PV panels are the energy supply devices for photovoltaic (PV) power generation. PV power plants typically use multiple PV panels combined into a large PV unit. This assembly of small PV panels into a large PV unit requires a PV support structure, which includes support piles and PV panel carriers. To complete PV power generation, the PV panels need to be mounted on the carriers, and the carriers need to be installed at a high location.

[0003] In large-area covered areas, such as flat roofs of large factories and flat ground, installation brackets are required. Photovoltaic panels must be screwed onto the bracket beams. During installation, the edges and corners of the photovoltaic panels must be aligned to ensure a neat and orderly arrangement without undulations or waves. Traditional installation methods require pre-measurement and marking to ensure neat panel placement, resulting in numerous and time-consuming marking points. Furthermore, the photovoltaic panels need to be installed at an angle, which may cause them to slip during manual lifting, further complicating the installation process.

[0004] In view of this, the present invention is hereby proposed. Summary of the Invention

[0005] In order to solve the technical problems existing in the prior art, the present invention provides a photovoltaic device. The photovoltaic device of the present invention has the advantages of neatly arranged photovoltaic carriers without undulations and waves, and high installation efficiency.

[0009] A support frame is provided with several sets of parallel connecting pipes, and a first limiting structure and a second limiting structure that cooperate with the positioning structure are provided on the parallel connecting pipes.

[0010] Parallel connecting pipes restrict the X-axis displacement of the photovoltaic carrier, the first limiting structure restricts the Y-axis displacement of the photovoltaic carrier, and the second limiting structure restricts the Z-axis displacement of the photovoltaic carrier.

[0011] Furthermore, the positioning structure includes an X-axis limiting platform, a Y-axis limiting platform, and a limiting groove.

[0012] Furthermore, the positioning structure is a channel steel, and two channel steels are symmetrically arranged on the photovoltaic carrier plate.

[0013] Furthermore, the first limiting structure includes a limiting platform, and limiting platforms are provided at both ends of the channel steel along its length.

[0014] Furthermore, the limiting platform is made of right-angled steel.

[0015] Furthermore, the second limiting structure includes a support plate, a double-sided rack, a gear, a locking rod, and a drive rod. The support plate is fixed on the support frame and is located between parallel connecting pipes.

[0016] On the back of the tray, one end of the drive rod is connected to the tray via a bearing, and the other end is threaded; the drive rod is connected to the double-sided rack via the thread, the double-sided rack meshes with the gear, the gear is rotatably connected to the tray, and the gear is connected to the locking rod;

[0017] The gear is driven to rotate by a double-sided rack, thereby causing the locking rod to rotate and engage with the limiting groove for limiting.

[0018] Furthermore, a guide strip is connected to the tray, and a guide groove is provided on the double-sided magnetic strip, with the guide strip disposed within the guide groove.

[0019] Furthermore, outside the guide groove, the guide strip is connected to a horizontal plate; the width of the horizontal plate is greater than the width of the guide groove.

[0020] Furthermore, the gear and the locking rod are integrally formed.

[0021] Furthermore, the connecting pipe is a square tube.

[0022] By adopting the above technical solution, the present invention has the following advantages:

[0024] 2. The photovoltaic device of the present invention has the advantage of high installation efficiency.

[0025] 3. The photovoltaic device of the present invention has the advantage of being easy to replace the photovoltaic substrate.

Detailed Implementation

[0033] The following description provides many different embodiments or examples for implementing various features of the invention. The elements and arrangements described in the specific examples below are only for concise expression of the invention and are merely examples, not intended to limit the invention.

[0034] In the description of this invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this invention, "a number" means one or more, and "a plurality of" means two or more, unless otherwise explicitly specified.

[0035] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] This embodiment provides a photovoltaic device, referring to... Figure 1 , Figure 2 As shown, it includes:

[0037] Photovoltaic carrier 1, such as Figure 2 As shown, a positioning structure 10 is provided on the back of the photovoltaic carrier 1;

[0038] The support frame 2 is provided with several sets of parallel connecting pipes 30, and a first limiting structure 40 and a second limiting structure 50 that cooperate with the positioning structure 10 are provided on the parallel connecting pipes 30.

[0039] The parallel connecting pipes 30 restrict the X-direction displacement of the photovoltaic carrier 1, the first limiting structure 40 restricts the Y-direction displacement of the photovoltaic carrier 1, and the second limiting structure 50 restricts the Z-direction displacement of the photovoltaic carrier 1.

[0040] like Figure 2 As shown, the support frame 2 includes two parallel crossbeams, which are preferably square tubes. Figure 2 The diagram shows only one set of parallel connecting pipes 30, with a photovoltaic carrier plate 1 mounted on the parallel connecting pipes 30. It should be noted that in actual use, the number of connecting pipes 30 and the number of photovoltaic carrier plates 1 can be set according to the usage requirements. Figure 2 In the structure shown, a set of parallel connecting pipes 30 can connect three photovoltaic carriers 1.

[0041] Furthermore, such as Figure 2 As shown, the positioning structure 10 includes an X-axis limiting platform 11, a Y-axis limiting platform 12, and a limiting groove 13. The X-axis limiting platform 11 cooperates with the connecting pipe 30 for limiting, the Y-axis limiting platform 12 cooperates with the first limiting structure 40 for limiting, and the limiting groove 13 cooperates with the second limiting structure 50 for limiting.

[0042] Furthermore, such as Figure 2 As shown, the positioning structure 10 is a channel steel, and two channel steels are symmetrically arranged on the photovoltaic carrier plate 1. The channel steel structure is simple, easy to obtain, and easy to connect with the photovoltaic carrier plate 1; and the structure of the channel steel itself satisfies the requirements of having an X-direction limiting platform 11, a Y-direction limiting platform 12, and a limiting groove 13.

[0043] Furthermore, such as Figure 3 As shown, the first limiting structure 40 includes a limiting platform 41, and both ends of the channel steel in the length direction are provided with limiting platforms 41.

[0044] Furthermore, the limiting platform 41 is made of right-angle steel. The limiting platform 41 is connected to the connecting pipe 30 by bolts, and the connection method is simple.

[0045] Furthermore, such as Figure 3 As shown, the second limiting structure 50 includes a support plate 51, a double-sided rack 52, a gear 53, a locking rod 54, and a drive rod 55. The support plate 51 is fixed on the support frame 2, and the support plate 51 is located between the parallel connecting pipes 30.

[0046] On the back of the tray 51, one end of the drive rod 55 is connected to the tray 51 via a shaft 80 bearing, and the other end is threaded; the drive rod 55 is connected to the double-sided rack 52 via the thread, the double-sided rack 52 meshes with the gear 53, the gear 53 is rotatably connected to the tray 51, and the gear 53 is connected to the locking rod 54;

[0047] Rotate the drive rod 55, which drives the double-sided magnetic strip to move. The double-sided rack 52 drives the gear 53 to rotate, thereby causing the locking rod 54 to rotate and engage with the limiting groove 13 for limiting.

[0048] The gear 53 can be rotatably connected to the support plate 51 via the shaft 80; specifically, the shaft 80 is fixedly connected to the support plate 51, and the gear 53 can be rotatably connected to the shaft 80 via the shaft 80.

[0049] It should be noted that the number of locking rods 54 and the number of secondary wheels are in one-to-one correspondence, and at least two opposing locking rods are required to fix a photovoltaic carrier plate 1.

[0050] Furthermore, such as Figure 1 , Figure 3 As shown, the tray 51 includes a support portion and a connecting portion. Both ends of the support portion are connected to the connecting portion, which is used to connect to the support frame 2. The support portion is used to support the photovoltaic carrier 1. Preferably, the tray 51 is connected to the support frame 2 via the connecting portion; the connecting portion is connected to the support frame 2 via threads (not shown in the figure). Based on this, the second limiting structure 50 can be disassembled and replaced.

[0051] Furthermore, such as Figure 3 , Figure 4As shown, a guide strip 60 is connected to the support plate 51, and a guide groove 521 is provided on the double-sided rack 52, with the guide strip 60 disposed within the guide groove 521. This guides the movement of the rack and improves the engagement effect between the locking rod 54 and the limiting groove 13.

[0052] Furthermore, such as Figure 3 , Figure 4 As shown, outside the guide groove 521, the guide strip 60 is connected to a horizontal plate 70; the width of the horizontal plate 70 is greater than the width of the guide groove 521. The width direction should be understood as... Figure 3 The direction indicated by the middle arrow serves to connect and support the double-sided rack 52.

[0053] Furthermore, the gear 53 and the locking rod are integrally formed. Since the locking rod 54 needs to cooperate with the limiting groove 13 to achieve Z-axis limiting, and also has an anti-pull-out effect, the rigidity of the locking rod 54 is improved, thus improving the anti-tensile plate effect.

[0054] Furthermore, the connecting pipe 30 is a square tube. The square tube can increase the contact area with the photovoltaic carrier plate 1, thereby improving its stability.

[0055] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
