Description

Technical Field

[0001] This utility model relates to the field of operation and maintenance technology of solar photovoltaic modules, and in particular to a photovoltaic module operation and maintenance frame. Background Technology

[0002] With the widespread application of photovoltaic power generation technology, the maintenance of rooftop photovoltaic modules is becoming increasingly important.

[0003] Traditional maintenance methods have the following problems:

[0004] The surface of frameless photovoltaic modules makes it impossible for people to stand directly, leading to maintenance difficulties;

[0005] Existing maintenance equipment is bulky and inconvenient to move;

[0006] Contact between the equipment and the components can easily cause damage to the components;

[0007] It cannot adapt to photovoltaic module arrays of different specifications. Utility Model Content

[0008] The purpose of this utility model is to provide a photovoltaic module maintenance rack to solve the technical problems in the prior art where people cannot stand directly on the surface of frameless photovoltaic modules, resulting in maintenance difficulties; and where contact between equipment and modules can easily cause damage to the modules.

[0009] To achieve the above objectives, the present invention provides a photovoltaic module maintenance frame, including a support frame made of aluminum alloy. One end of the support frame has two downward-extending legs, and the other end has two downward-extending legs. The legs can slide along the length of the support frame and are locked in place by locking screws. The support frame is suspended above the photovoltaic module, which is fixed to the roof. The support frame spans the photovoltaic module, with the two legs at one end resting on the roof surface outside one end of the photovoltaic module, and the two legs at the other end resting on the roof surface outside the other end of the photovoltaic module. A space is provided between the support frame and the photovoltaic module.

[0010] Furthermore, the support includes two parallel crossbeams and a plurality of foot rods disposed between the two crossbeams, with two foot rods at one end of each of the two crossbeams and two foot rods at the other end of each of the two crossbeams.

[0011] Furthermore, the support leg can slide along the length of the crossbeam, and the support leg is fitted with a locking screw, which can lock the support leg onto the crossbeam to accommodate photovoltaic modules of different widths.

[0012] Furthermore, the upper end of the support leg is provided with a sliding groove, which slides in conjunction with the crossbeam. The side wall of the sliding groove is provided with the locking screw, and the lower end of the support leg rests on the roof.

[0013] Furthermore, the support leg is made of metal, and the lower end of the support leg is provided with an elastic protective layer.

[0014] Furthermore, the support legs are made of aluminum alloy, the elastic protective layer is a rubber protective layer or a polyurethane protective layer, and rubber sleeves are provided at both ends of the crossbeam.

[0015] Furthermore, the support leg is either an integral structure or a modular assembly structure. The integral structure is integrally formed, while the modular assembly structure is formed by detachably assembling the upper end and the lower end of the support leg.

[0016] Furthermore, a connecting plate is screwed between several of the pedals, and the connecting plate is located below the several pedals.

[0017] Furthermore, the photovoltaic module is a frameless photovoltaic module, and the roof is a corrugated steel roof.

[0018] Furthermore, the roof is provided with several parallel flanges, and the two sides of the photovoltaic module are respectively fixed to the flanges on both sides by fixing blocks, and the support is located between the flanges on both sides.

[0019] In summary, the technical solution of this utility model has the following beneficial effects: The structural design of this utility model is reasonable. The bracket is made of aluminum alloy, with two downward-extending legs at one end and two downward-extending legs at the other end. The legs can slide along the length of the bracket and are locked in place by locking screws. The bracket is suspended above the photovoltaic module, which is fixed above the roof. The bracket spans the photovoltaic module, with two legs at one end resting on the roof surface beyond one end of the photovoltaic module, and two legs at the other end resting on the roof surface beyond the other end of the photovoltaic module. There is a gap between the bracket and the photovoltaic module. Therefore, the bracket is lightweight and high-strength. Made of aluminum alloy profiles, the total weight can be reduced to about 5kg, making it easy to carry with one hand. The legs slide along the length of the bracket to accommodate photovoltaic modules of different widths. When moved to the desired position, the legs are locked to the bracket with locking screws. With the support of the four legs and the roof, the bracket can be stably suspended above the photovoltaic modules, allowing people to stand directly on the bracket above the photovoltaic modules for safe maintenance of the photovoltaic modules (such as frameless photovoltaic modules). Furthermore, there is a gap between the bracket and the photovoltaic modules, preventing the bracket from contacting the photovoltaic modules (such as frameless photovoltaic modules) and avoiding the risk of damage to the photovoltaic modules.

[0031] See Figures 1 to 7This embodiment provides a photovoltaic module maintenance frame, including a support 1, which is made of aluminum alloy. One end of the support 1 has two downward-extending legs 2, and the other end of the support 1 has two downward-extending legs 2. The legs 2 can slide along the length of the support 1 and are locked in place by locking screws 5. The support 1 is suspended above the photovoltaic module 3, and the photovoltaic module 3 is fixed above the roof 4. The support 1 spans the photovoltaic module 3, with the two legs 2 at one end resting on the roof 4 outside one end of the photovoltaic module 3, and the two legs 2 at the other end resting on the roof 4 outside the other end of the photovoltaic module 3. There is a gap between the support 1 and the photovoltaic module 3. Function: The bracket is made of lightweight, high-strength aluminum alloy profiles, reducing its total weight to approximately 5kg, allowing for one-handed handling. The legs slide along the length of the bracket, accommodating photovoltaic modules of varying widths. Once moved to the desired position, the legs are secured to the bracket with locking screws. With the support of the four legs and the roof, the bracket can stably suspend above the photovoltaic modules, allowing people to stand directly on the bracket above the modules for safe maintenance of the photovoltaic modules (e.g., frameless photovoltaic modules). Furthermore, the bracket has a gap between itself and the photovoltaic modules, preventing contact and avoiding damage to the modules.

[0032] Specifically, the support frame 1 includes two parallel crossbeams 101 and several footrests 102 disposed between the two crossbeams 101. Two feet 2 at one end are respectively disposed at one end of the two crossbeams 101, and two feet 2 at the other end are respectively disposed at the other end of the two crossbeams 101. Function: The arrangement of the crossbeams 101 and footrests 102 makes the support frame 1 not only lightweight but also convenient for personnel to step on during operation.

[0033] Specifically, the support leg 2 can slide along the length of the crossbeam 101. The support leg 2 is fitted with a locking screw 5, which secures the support leg 2 to the crossbeam 101 to accommodate photovoltaic modules 3 of different widths. Function: By sliding the support leg 2 along the length of the crossbeam 101, it can accommodate photovoltaic modules of different widths. When moved to the desired position, the locking screw 5 secures the support leg 2 to the crossbeam 101. See also... Figure 7 The different first widths 11 between the two legs can be adjusted according to the different second widths 10 of the photovoltaic modules.

[0034] Specifically, the upper end of the support leg 2 is provided with a sliding groove 201, which slides in conjunction with the crossbeam 101. A locking screw 5 is provided on the side wall of the sliding groove 201, and the lower end of the support leg 2 rests on the roof 4. Function: Because the sliding effect of the sliding groove 201 is relatively stable, the design can be well adjusted to adapt to various component specifications. Preferably, the locking screw 5 is a wing bolt. The bracket is rectangular, and its length is slightly larger than the width of the photovoltaic module, so that the bracket 1 can span the photovoltaic module 3 without making the bracket too large.

[0035] Specifically, the support leg 2 is made of metal, and the lower end of the support leg 2 is provided with an elastic protective layer 6. Function: This provides both the strength of metal and the elastic protection of an elastic component, so that when the lower end of the support leg 2 rests directly on the roof, it will not damage the roof or its components.

[0036] Specifically, the support leg 2 is made of aluminum alloy, and the elastic protective layer 6 is a rubber protective layer or a polyurethane protective layer; rubber sleeves 7 are provided at both ends of the crossbeam 101. Function: The support leg 2 is made of lightweight, high-strength aluminum alloy profiles to reduce weight; the rubber sleeves 7 prevent the ends of the crossbeam 101 from being too sharp, protecting the roof and component surfaces. Preferably, the bracket 1 is made of 6061 aluminum alloy.

[0037] Specifically, the support leg 2 can be a one-piece structure or a modular assembly structure. The one-piece structure is molded in one piece, while the modular assembly structure is composed of detachable upper and lower parts of the support leg. Function: The one-piece and modular assembly structures respectively offer advantages of high strength and good flexibility; the appropriate option can be selected based on the needs.

[0038] Specifically, a connecting plate 8 is screwed between several foot levers 102, and the connecting plate 8 is located below the foot levers 102. Function: The connecting plate strengthens the support structure.

[0039] Specifically, photovoltaic module 3 is a frameless photovoltaic module, and roof 4 is a corrugated steel roof. Purpose: This design better suits practical work needs; of course, other roof types or other photovoltaic modules would also be acceptable.

[0040] Specifically, the roof 4 has several parallel flanges 401. The two sides of the photovoltaic module 3 are fixed to the flanges 401 by fixing blocks 9. The support legs 2 are located between the flanges 401. Function: The photovoltaic module 3 can be stably suspended above the roof 4.

[0041] In summary, this utility model provides a lightweight, adjustable maintenance frame that does not damage photovoltaic modules.

[0042] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
