DETAILED DESCRIPTION

[0039] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0040] Please refer to Figures 1-5 The present application provides the following technical solutions: a track sliding type photovoltaic panel replacement support, comprising a fixed guide rail 1, a guide chute 11 is formed on the top of the fixed guide rail 1, further comprising: a telescopic support 2, a mounting cross beam 3 and an adjusting assembly 4.

[0041] Further, as shown in Figure 1 In the embodiment, the telescopic support 2 is slidingly connected to the fixed guide rail 1, the center of gravity of the mounting cross beam 3 is hingedly connected to the top end of the telescopic support 2, and the adjusting assembly 4 is connected between the telescopic support 2 and the mounting cross beam 3, used for adjusting the inclination angle of the mounting cross beam 3. After the above scheme is adopted, in use, the fixed guide rail 1 serves as a support base and is made of high-strength aluminum alloy or steel material, and the guide chute 11 is formed on the surface for limiting the sliding path of the telescopic support 2. The center of gravity of the cross beam 3 is hingedly connected to the top end of the support 2 through a pin shaft or a bearing, allowing the cross beam 3 to freely rotate around the fulcrum. The photovoltaic panel is mounted on the cross beam 3 and is fixed by a clamp or a bolt to ensure the structural stability.

[0042] The telescopic support 2 is moved along the fixed guide rail 1, and when the photovoltaic panel needs to be repaired or replaced, the photovoltaic panel can be quickly moved to the repair area, and the installation spacing of adjacent two photovoltaic panels can also be adjusted according to actual use requirements.

[0043] In this invention, the center of gravity of the mounting beam 3 is hinged to the top of the telescopic support column 2. Therefore, no matter what tilt angle the mounting beam 3 is adjusted to, the center of gravity of the mounting beam 3 is always in the supporting direction of the telescopic support column 2, which greatly improves the stability of the telescopic support column 2 and the mounting beam 3 and avoids accidents caused by external forces to cause the telescopic support column 2 and the mounting beam 3 to tip over during outdoor use.

[0044] Preferably, by Figure 1 and Figure 2 As shown, this embodiment also includes: an I-shaped slider 6 and a No. 3 locking bolt 7. The I-shaped slider 6 is slidably installed in the guide groove 11. The telescopic support column 2 is fixed to the top of the I-shaped slider 6, and a threaded hole is machined on the I-shaped slider 6. Multiple No. 1 positioning holes 12 are equally spaced along the length direction on the outer wall of the fixed guide rail 1. The No. 3 locking bolt 7 passes through the No. 1 positioning hole 12 and is fixedly connected to the I-shaped slider 6 by thread engagement. With the above scheme, when in use, the cross-section of the I-shaped slider 6 is I-shaped, which matches the contour of the guide groove 11 to ensure the stability during sliding. The bottom of the I-shaped slider 6 is embedded in the groove 11 of the guide rail, and the top is welded and fixed to the bottom end of the telescopic support column 2.

[0045] Users can select the position of positioning hole 12 according to their needs to achieve precise adjustment of the horizontal position of the photovoltaic panel (such as adjusting the spacing to avoid obstacles).

[0046] When adjusting the position of the photovoltaic panel, first loosen the No. 3 locking bolt 7, then push the telescopic support 2 along the length of the guide groove 11. After the photovoltaic panel is adjusted to the appropriate position, tighten the No. 3 locking bolt 7 to lock it, ensuring the stability of the photovoltaic panel after adjustment.

[0047] Preferably, by Figure 1 and Figure 2 As shown in this embodiment, the outer wall of the I-shaped slider 6 abuts against the inner wall of the guide groove 11. With the above solution, when in use, the top and bottom flanges of the I-shaped slider 6 abut against the upper and lower inner walls of the guide groove 11 respectively, forming a three-point contact (top flange, bottom flange, and web), ensuring the anti-overturning ability during sliding.

[0048] By surface polishing (Ra≤0.8μm) or applying a lubricant (such as a molybdenum disulfide coating), the coefficient of friction between the I-shaped slider 6 and the guide groove 11 is reduced to below 0.1, thus achieving smooth sliding.

[0049] Optionally, by Figure 1 and Figure 3As shown, in the embodiment, the adjusting assembly 4 comprises a control frame 41 and two threaded rods 42, threaded holes are formed at both ends of the control frame 41, the two threaded rods 42 are oppositely threaded and are respectively hinged to the telescopic support 2 and the mounting beam 3, the proximal ends of the two threaded rods 42 penetrate through the control frame 41 and are connected to the control frame 41 by screwing, after using the above scheme, the control frame 41 is manually rotated, due to the opposite threads of the two threaded rods 42, the two threaded rods 42 will move synchronously inward or outward, thereby changing the included angle between the telescopic support 2 and the mounting beam 3.

[0050] The movement of the threaded rod 42 is converted into the inclination angle of the mounting beam 3, for example, the threaded rod 42 moves 10 mm, the beam inclination angle changes about 3° (the specific value depends on the distance between the hinge points), and the inclination angle of the mounting beam 3 is adjusted.

[0051] Preferably, by Figure 1 and Figure 3 As shown, in the embodiment, the adjusting assembly 4 further comprises a limiting disc 43, the limiting disc 43 is fixed to the proximal end of the threaded rod 42, after using the above scheme, the limiting disc 43 is fixed to the proximal end of the threaded rod 42 (the end close to the control frame 41), coaxial with the threaded rod 42.

[0052] The diameter of the limiting disc 43 is slightly larger than the inner diameter of the threaded hole of the control frame 41 (for example, the threaded hole diameter of the control frame 41 is φ30 mm, and the diameter of the limiting disc 43 is φ32 mm), forming a rigid stop for limiting the movement range of the threaded rod 42.

[0053] Preferably, by Figure 1 and Figure 4 As shown, in the embodiment, the adjusting assembly 4 further comprises a guiding assembly 5 for supporting and guiding the mounting beam 3, wherein the guiding assembly 5 comprises two arc-shaped positioning plates 51 and two locking bolts 52, the two arc-shaped positioning plates 51 are symmetrically fixed to the bottom surface of the mounting beam 3, and a plurality of second positioning holes 511 are formed on the arc-shaped positioning plate 51 and are equally spaced in the circumferential direction, the two locking bolts 52 are fixedly connected to the telescopic support 2 by penetrating through the arc-shaped positioning plate 51 and screwing, after using the above scheme, the top end of the telescopic support 2 and the two arc-shaped positioning plates 51 form a triangular support, dispersing the photovoltaic panel load and improving the anti-overturning ability (compared with the single-point hinge design, the bearing capacity is improved by 40%).

[0054] When the installation beam 3 is adjusted in the inclination angle by the adjusting assembly 4, the No. 2 locking bolt 52 is first unscrewed, and the installation beam 3 is rotated to synchronously rotate the arc-shaped positioning plate 51, so that the No. 2 positioning hole 511 at different positions is correspondingly matched with the threaded hole on the telescopic support column 2. When the installation beam 3 is adjusted to the appropriate angle, the No. 2 locking bolt 52 is screwed through the arc-shaped positioning plate 51 and fixedly connected with the telescopic support column 2 in the threaded manner, so as to be locked.

[0055] Preferably, as shown in Figure 1 and Figure 5 In the embodiment, the telescopic support column 2 includes an outer support column 21, an inner support column 22 and a No. 1 locking bolt 23. The outer support column 21 has a connecting cavity 211, and the inner support column 22 is partially embedded in the connecting cavity 211 to form a telescopic structure. A plurality of positioning grooves 221 are arranged on the outer wall of the inner support column 22 and are equidistantly distributed in the vertical direction. The No. 1 locking bolt 23 is screwed on the outer support column 21, and one end of the No. 1 locking bolt 23 is embedded in the positioning groove 221. After the above scheme is used, in use, the outer support column 21 is made of aluminum alloy (such as 6061-T6) or hot-dip galvanized steel material. The inner wall of the connecting cavity 211 is precisely processed (Ra≤1.6 μm) to ensure smooth cooperation with the inner support column 22.

[0056] The cross section of the connecting cavity 211 is matched with the inner support column 22 (such as rectangular or circular), so as to provide vertical direction guidance and prevent the inner support column 22 from laterally shaking.

[0057] The inner support column 22 can be slid to the target height by loosening the No. 1 locking bolt 23 without disassembling other assemblies. If the inner support column 22 is damaged, it can be individually extracted and replaced to avoid the whole support column being scrapped.

[0058] Preferably, as shown in Figure 1 and Figure 5 In the embodiment, the outer wall of the inner support column 22 abuts against the inner wall of the connecting cavity 211. After the above scheme is used, in use, the outer wall of the inner support column 22 and the inner wall of the connecting cavity 211 are matched in the gap (such as H7 / g6 tolerance), and the single-side gap is controlled within 0.05-0.1 mm, so as to ensure smooth sliding while limiting lateral displacement.

[0059] The inner wall of the connecting cavity 211 and the outer wall of the inner support column 22 are in large-area contact (contact area≥80%) to transfer the load, so as to avoid single-point stress concentration. For example, under the snow load of 2kN / m 2 , the uniformity of the contact stress distribution is improved by 40%.

[0060] The inner support column 22 and the outer support column 21 are made of the same material (such as 6061-T6 aluminum alloy), so as to reduce the risk of jam caused by thermal expansion difference; the inner wall of the connecting cavity 211 and the outer wall of the inner support column 22 are subjected to anodization (film thickness: 15-20 μm) or PTFE spraying, so as to reduce the friction coefficient to below 0.1 and enhance corrosion resistance.

[0061] Parts not described in detail herein are prior art.

[0062] The working principle and use process of the rail sliding type photovoltaic panel replacement support are as follows: in use, the fixed guide rail 1 is used as a support base and is made of high-strength aluminum alloy or steel material, a guide sliding groove 11 is formed on the surface of the fixed guide rail 1 and is used for limiting the sliding path of the telescopic support column 2, the center of gravity of the cross beam 3 is hingedly connected to the top end of the telescopic support column 2 through a pin shaft or a bearing, so that the cross beam 3 is allowed to freely rotate around the fulcrum, the photovoltaic panel is installed on the cross beam 3 and is fixed through clamps or bolts, so as to ensure the structural stability.

[0063] The telescopic support column 2 is moved along the fixed guide rail 1, and when the photovoltaic panel needs to be repaired or replaced, the photovoltaic panel can be quickly moved to a repair area, and the installation spacing of adjacent two photovoltaic panels can also be adjusted according to actual use requirements.

[0064] The control frame 41 is manually rotated, and due to the reverse threads of the threaded lead screws 42, the two threaded lead screws 42 are synchronously moved inward or outward, so as to change the included angle between the telescopic support column 2 and the installation cross beam 3.

[0065] In the utility model, the center of gravity of the installation cross beam 3 is hingedly connected to the top end of the telescopic support column 2, so that no matter what the inclination angle of the installation cross beam 3 is, the center of gravity of the installation cross beam 3 is always in the support direction of the telescopic support column 2, the stability of the telescopic support column 2 and the installation cross beam 3 is greatly improved, and accidents of the telescopic support column 2 and the installation cross beam 3 accidentally falling due to external force in outdoor use are avoided.
