When the roof space is limited, reserving the maintenance channel will reduce the arrangement rate of photovoltaic modules and fail to maximize the use of roof arrangement resources. Utility Model Content

[0005] The present application provides a push-pull maintenance channel for photovoltaic modules, aiming to solve the problem that reserved maintenance channels need to occupy roof space during the arrangement of photovoltaic modules. When the roof space is limited, the reserved maintenance channels will reduce the arrangement rate of photovoltaic modules and fail to maximize the use of roof arrangement resources.

The second vertical beam is fixed between the first horizontal beam and the second horizontal beam. The top of the first vertical beam is fixed to the red bar through a connecting beam, and the telescopic ladder is connected to the second horizontal beam.

[0009] Preferably, the telescopic ladder comprises a plurality of pedals and hinges, and the plurality of hinges are evenly installed between the pedals and the second cross beam and between adjacent pedals.

[0010] Preferably, the hinge comprises a first hinge and a second hinge, and the first hinge is hinged to the second hinge.

[0013] Preferably, a mounting seat is fixed to the back of the telescopic ladder, and the mounting seat includes an integrated bracket and a base. There are two brackets, and one end of the auxiliary support member is hinged between the two brackets.

[0014] Preferably, a limiting assembly for accommodating the auxiliary support member is also fixed to the back of the telescopic ladder, the limiting assembly is located above the mounting seat, and the limiting assembly is engaged with the auxiliary support member.

[0015] Preferably, reinforcement pieces are fixed between the base frame and the strips on both sides.

[0016] The utility model has the following beneficial effects:

[0017] This solution sets up an inspection channel under the photovoltaic components, which does not need to occupy the roof layout resources, can lay photovoltaic components to the maximum extent, and maximize the use of roof layout resources; when inspection is required, the photovoltaic components above the inspection channel are automatically opened under the action of the first electric push rod, and the telescopic ladder is automatically unfolded under the action of the second electric push rod.

DETAILED DESCRIPTION

[0023] Example 1

[0024] like Figure 1-4 As shown, a push-pull maintenance channel of a photovoltaic component includes a rail 6, a base frame 3 is fixed between the rails 6 on both sides of the photovoltaic component 5, the base frame 3 is connected to a first electric push rod 1, the upper end of the first electric push rod 1 is hinged to one end of the photovoltaic component 5, the lower end of the first electric push rod 1 is hinged to the base frame 3, a telescopic ladder 4 is installed at the bottom of the base frame 3, and an auxiliary support member 7 is hinged on the back of the telescopic ladder 4.

[0025] One end of the photovoltaic component 5 is hinged to the first electric push rod 1, and the other end is also hinged during installation, so that it can be pushed open or closed by the first electric push rod 1 like a window. Not all photovoltaic components 5 need to be hinged during installation. Only photovoltaic components 5 corresponding to maintenance channels require this design.

[0026] The base frame 3 includes a first vertical beam 31, a first horizontal beam 32, a second vertical beam 33 and a second horizontal beam 34. There are two first vertical beams 31. The first horizontal beam 32 and the second horizontal beam 34 are respectively fixed between the two first vertical beams 31. The second vertical beam 33 is fixed between the first horizontal beam 32 and the second horizontal beam 34. The top of the first vertical beam 31 is fixed to the sandalwood bar 6 through a connecting beam, and the telescopic ladder 4 is connected to the second horizontal beam 34.

[0027] like Figure 1 As shown, the connecting beam is a cross beam fixed between two beams 6.

[0028] The telescopic ladder 4 includes a plurality of pedals 41 and hinges 42 . The plurality of hinges 42 are evenly installed between the pedals 41 and the second beam 34 and between adjacent pedals 41 .

[0029] The hinge 42 includes a first hinge 421 and a second hinge 422 , and the first hinge 421 is hinged to the second hinge 422 .

[0030] Second electric push rods 43 are respectively provided between the pedal 41 and the second cross beam 34 and between adjacent pedals 41 .

[0031] The second electric push rod 43 is disposed between the pedal 41 and the second cross beam 34 and between adjacent pedals 41 like the hinge 42. Two or more second electric push rods 43 are disposed on each layer and are evenly distributed on both sides of the device to avoid hindering the climbing of workers.

[0032] When in use, under the action of multiple second electric push rods 43, the pedals 41 of the telescopic ladder 4 are gradually unfolded section by section. When not in use, under the action of multiple second electric push rods 43, the multiple-section pedals 41 are gradually retracted, and finally retracted into a smaller space to avoid affecting the activities of people below.

[0033] A mounting base 44 is fixed to the back of the telescopic ladder 4 . The mounting base 44 includes an integrated bracket 441 and a base 442 . There are two brackets 441 , and one end of the auxiliary support member 7 is hinged between the two brackets 441 .

[0034] The auxiliary support member 7 is used to form a triangular structure after the telescopic ladder 4 is unfolded, with one end of the auxiliary support member 7 abutting against the telescopic ladder 4 and the other end abutting against the ground, thereby improving the stability of the telescopic ladder 4.

[0035] A limiting assembly 45 for accommodating the auxiliary support member 7 is also fixed to the back of the telescopic ladder 4 . The limiting assembly 45 is located above the mounting seat 44 , and the limiting assembly 45 is engaged with the auxiliary support member 7 .

[0036] The limiting assembly 45 is engaged with the auxiliary support member 7, which means that the auxiliary support member 7 is engaged between the limiting assemblies 45 to achieve a storage effect, so that the auxiliary support member 7 will not hang vertically when the telescopic ladder 4 is not in use; the auxiliary support member 7 can slide up and down between the limiting assemblies 45 on both sides. Because the telescopic ladder 4 needs to be expanded and contracted, the engagement only has a limited engagement effect at the entrance of the limiting assemblies 45 on both sides, which restricts the auxiliary support member 7 to the inside to prevent it from falling out.

[0037] Example 2

[0038] The difference between this embodiment and embodiment 1 is that: Figure 3 As shown, the second electric push rod 43 is located at the back of the telescopic ladder 4.

[0039] The second electric push rod 43 is not arranged on the inner side of the upper and lower devices, but is arranged on the back, which can also achieve the same effect.

[0040] Example 3

[0041] The difference between this embodiment and embodiment 1 is that: Figure 1 As shown, reinforcement members 2 are respectively fixed between the base frame 3 and the strips 6 on both sides.

[0042] Because a telescopic ladder 4 is installed below the base frame 3, in order to improve stability and rigidity, a reinforcing member 2 is installed to make the structure more stable.

[0043] The above description is only a specific embodiment of the present invention, but the technical features of the present invention are not limited thereto. Any changes or modifications made by any technician in the field of the present invention are included in the patent scope of the present invention.
