Specific embodiments

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1-6 , the present utility model provides a technical solution: a special ladder for replacing photovoltaic modules, including a set of symmetric upper ladder beams 1 and a set of symmetric lower ladder beams 2. The adjacent upper ladder beam 1 and lower ladder beam 2 are hinged. A plurality of upper pedals 3 with the same intervals are fixedly arranged between the two upper ladder beams 1 from top to bottom. A plurality of lower pedals 4 with the same intervals are fixedly arranged between the two lower ladder beams 2 from top to bottom. Open slots are provided at the rear ends of the upper ladder beams 1. A baffle 7 with a serrated upper end surface is inserted into the open slots. An adjusting component is meshed and connected to the upper side of the baffle 7. A retaining groove 15 is provided at the lower side of the baffle 7.

[0024] First, move the upper ladder beam 1 of the device to the top edge position of the photovoltaic panel. Through the adjustment component, move the baffle 7 forward along the opening slot, extend the baffle 7 out of the upper ladder beam 1 and extend it to the edge position of the photovoltaic panel, so that the edge position of the photovoltaic panel enters the retaining groove 15 of the baffle 7, which facilitates the staff to replace the photovoltaic module through this device and reduces the damage to other photovoltaic panels when the staff replaces the photovoltaic module. After replacing the photovoltaic module, move the baffle 7 upward. When the retaining groove 15 of the baffle 7 is disengaged from the edge side of the photovoltaic panel, under the cooperation of the baffle 7 and the adjustment component, the baffle 7 returns to its initial position, thereby retracting the baffle 7 into the upper ladder beam 1. By rotating the two upper ladder beams 1, the two upper ladder beams 1 are folded towards the direction of the two lower ladder beams 2, thereby playing the role of retracting the device and reducing the space occupied by the device.

[0025] The adjustment component includes an adjustment gear 12 meshed and connected to the upper side of the baffle 7. A stepped shaft 11 is fixedly connected to the center of the adjustment gear 12. The stepped shaft 11 is rotatably connected to the upper ladder beam 1. Protective plates 13 are fixedly connected to the left and right ends of the adjustment gear 12. A torsion spring 14 is fixedly arranged between the protective plates 13 and the inner wall of the upper ladder beam 1. The torsion spring 14 is sleeved outside the stepped shaft 11. A steel wire rope 16 is wound around the right side of the stepped shaft 11. One end of the steel wire rope 16 is fixedly connected to the stepped shaft 11, and the other end of the steel wire rope 16 is fixedly connected to a pull rod 17 and passes through the outside of the upper ladder beam 1. By pulling down the steel wire rope 16, the steel wire rope 16 drives the stepped shaft 11 to rotate. The stepped shaft 11 drives the adjustment gear 12 to rotate. The adjustment gear 12 drives the baffle 7 to move forward, so that the baffle 7 moves towards the edge position of the photovoltaic panel, thereby facilitating the suspension of the baffle 7 on the edge side of the photovoltaic panel. When the position of the upper ladder beam 1 is moved upward, it drives the baffle 7 to move upward. The retaining groove 15 of the baffle 7 contacts the edge side of the photovoltaic panel. When the retaining groove 15 of the baffle 7 is disengaged from the edge side of the photovoltaic panel, under the action of the torsion spring 14, the stepped shaft 11 rotates in the reverse direction, thereby driving the baffle 7 to move backward, thus retracting the baffle 7.

[0026] A sliding groove is opened in the middle of the baffle 7, and a sliding plate 8 is inserted into the sliding groove. The sliding plate 8 is fixedly connected to the upper ladder beam 1. Through the insertion of the sliding plate 8 into the sliding groove, it is convenient for the baffle 7 to move freely in the front and back positions.

[0027] A limiting rod 9 is fixedly connected to the rear end of the baffle 7. A U-shaped long plate 10 is arranged on the lower side of the baffle 7. The bottom of the baffle 7 passes through the inside of the U-shaped long plate 10 and slides freely along the front and back positions of the U-shaped long plate 10. The limiting rod 9 is located above the upper end surface of the U-shaped long plate. The width of the opening slot is smaller than the length of the limiting rod 9. The use of the limiting rod 9 limits the displacement of the baffle 7 moving forward along the opening slot.

[0028] At the lower end of the upper ladder beam 1 and the upper end of the lower ladder beam 2, hollow sleeves 21 are fixedly connected. A pin rod 20 is inserted into the two sleeves 21. An insertion hole is formed in the lower sleeve 21, and a locking screw 19 is inserted into the insertion hole. The locking screw 19 is in threaded connection with the pin rod 20. By inserting the pin rod 20 into the two sleeves 21, it is convenient to fix the positions of the upper ladder beam 1 and the lower ladder beam 2 after being opened. By the threaded connection between the locking screw 19 and the pin rod 20, it is used to fix the position of the pin rod 20 in the two sleeves 21.

[0029] A collar 18 is fixedly connected to the lower end position of the upper ladder beam 1. A fixed cylinder 6 is rotatably connected inside the collar 18. Support rods 5 are fixedly connected to both ends of the fixed cylinder 6. The support rods 5 are fixedly connected to the lower ladder beam 2. By the combined use of the collar 18 and the fixed cylinder 6, it is convenient to fold the upper ladder beam 1 and the lower ladder beam 2, reducing the space volume of the device.

[0030] When the present utility model is in use, first move the upper ladder beam 1 of the device to the top edge position of the photovoltaic panel. Through the adjustment component, move the baffle 7 forward along the opening groove, extend the baffle 7 out of the upper ladder beam 1 and extend to the edge position of the photovoltaic panel, so that the edge position of the photovoltaic panel enters the retaining groove 15 of the baffle 7, which is convenient for the staff to repair and replace the photovoltaic components through the device, reducing the damage to other photovoltaic panels when the staff replaces the photovoltaic components. After replacing the photovoltaic components, move the baffle 7 upward. After the retaining groove 15 of the baffle 7 is disengaged from the edge side of the photovoltaic panel, under the cooperation of the baffle 7 and the adjustment component, the baffle 7 returns to the initial position, thereby retracting the baffle 7 into the upper ladder beam 1. By rotating the two upper ladder beams 1, the two upper ladder beams 1 are folded towards the two lower ladder beams 2, thereby playing a role in retracting the device and reducing the space usage volume of the device.

[0031] Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
