At the same time, the backrest can be ventilated to improve user comfort.

[0006] A photovoltaic power station operation and maintenance device includes a tray with casters mounted on its lower end face. A backrest is rotatably connected to the tray via a hinge. A first groove is formed on one side of the backrest, and a support plate is rotatably connected within the first groove. A second groove is formed on the tray, and multiple locking blocks are fixedly connected at equal intervals within the second groove. Ventilation holes are formed at equal intervals on the backrest, connecting to the side walls of the backrest. Breathing holes are formed on the back surface of the backrest, connecting to the ventilation holes.

[0007] Furthermore, a locking rod is fixedly connected to the free end of the support plate.

[0008] Furthermore, a headrest is fixedly attached to the backrest panel.

[0009] Furthermore, upright plates are fixed to both sides of the backrest panel, and rotating rods are rotatably connected through the two upright plates. A mounting frame is fixed to the rotating rod, and a transparent protective plate is fixed inside the mounting frame.

[0010] Furthermore, two limiting blocks are fixedly connected to the sides of the two upright plates that are far apart from each other, and abutment blocks are fixedly connected to both ends of the rotating rod.

[0011] Furthermore, an operating lever is fixedly connected to the abutment block.

[0012] Furthermore, a surrounding frame is fixedly connected to the mounting frame.

[0013] Furthermore, a third groove is provided on the mounting frame.

[0014] Furthermore, a hip pad is fixedly attached to the support plate.

[0015] Furthermore, a lumbar support is fixedly attached to the backrest.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] In this invention, by providing ventilation holes and air vents, when the worker's back is against the backrest, the ventilation holes and air vents work together to improve the airflow efficiency between the backrest and the worker's back, thereby improving back comfort. The backrest can be rotated and lifted to remove the support plate, and the free end of the support plate can be placed against the appropriate locking block, so that an angle is formed between the backrest and the support plate. The worker can then lie on the support plate and the backrest, which facilitates the inspection and maintenance of lines at different heights on the back of the photovoltaic panel.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Specific implementation examples:

[0027] like Figure 1-5 As shown, a photovoltaic power station operation and maintenance device includes a support plate 1. A caster wheel 2 is installed on the lower end face of the support plate 1 for movement. A backrest plate 4 is rotatably connected to the support plate 1 via a hinge 3. A first groove 5 is formed on the side of the backrest plate 4 closest to the support plate 1. A support plate 6 is rotatably connected within the first groove 5. A second groove 7 is formed on the support plate 1. Multiple locking blocks 8 are fixedly connected at equal intervals along the length of the second groove 7. Multiple ventilation holes 9 are formed at equal intervals on the backrest plate 4, communicating with the two side walls of the backrest plate 4. Ventilation holes 10 are formed on the back surface of the backrest plate 4, communicating with the ventilation holes 9. With ventilation holes 9 and air vents 10, when the back of the worker is against the backrest 4, the ventilation holes 9 and air vents 10 work together to improve the airflow efficiency between the backrest 4 and the worker's back, thus improving back comfort. The backrest 4 is rotated and lifted, the support plate 6 is pulled out, and the free end of the support plate 6 is placed against the appropriate position of the locking block 8, so that the backrest 4 and the support plate 1 form an angle. The worker can then lie on the support plate 1 and the backrest 4, which facilitates the inspection and maintenance of lines at different heights on the back of the photovoltaic panel.

[0028] like Figure 1-5 As shown, a locking rod 11 is fixedly connected to the free end of the support plate 6. The support plate 6 and the locking rod 11 can rotate into the first groove 5, so as not to affect the flatness of the backrest 4 (the backrest 4 rotates closer to and fits against the support plate 1). The opening of the locking block 8 is an arc shape adapted to the locking rod 11. By rotating and adjusting the support plate 6, the locking rod 11 and the locking block 8 are engaged and abutted to support the backrest 4.

[0029] like Figure 1-5 As shown, a headrest 12 is fixedly connected to the backrest 4 to improve the head comfort of the staff; upright plates 13 are fixedly connected to both sides of the backrest 4 away from the support plate 1, and rotating rods 14 are rotatably connected through the two upright plates 13. A mounting frame 15 is fixedly connected to the rotating rod 14, and a transparent protective plate 16 is fixedly connected inside the mounting frame 15. In this embodiment, the transparent protective plate 16 is made of transparent acrylic sheet. By setting the mounting frame 15 and the transparent protective plate 16, the face of the staff is protected to prevent the face from being hit by falling parts.

[0030] like Figure 1-5 As shown, two limiting blocks 17 located on the same horizontal plane are fixedly connected to the sides of the two upright plates 13 that are far apart from each other. Both ends of the rotating rod 14 are fixedly connected to abutment blocks 18. When the mounting frame 15 is rotated, the rotation of the rotating rod 14 can be limited by the abutment block 18 and any of the limiting blocks 17, thereby opening or closing the face protection function of the device.

[0031] like Figure 1-5 As shown, an operating lever 19 is fixedly connected to the abutment block 18. The operating lever 19 is provided to facilitate the worker's operation of rotating the rotating rod 14.

[0032] like Figure 1-5 As shown, a surrounding frame 20 is fixedly connected to the mounting frame 15. A third groove 21 is provided on the mounting frame 15. If a part falls onto the transparent protective plate 16, the surrounding frame 20 helps to collect the part. The third groove 21 provides space for the worker's head and neck, allowing the head to leave the area below the mounting frame 15 without rotating the rotating rod 14.

[0033] like Figure 1-5 As shown, a hip pad 22 is fixedly connected to the support plate 1, and a lumbar support 23 is fixedly connected to the backrest plate 4, which improves the comfort of the worker.

[0034] like Figure 1-5 As shown, lamps 24 are installed on both sides of the tray 1 near the headrest 12. The lamps 24 are installed to provide illumination during operation and maintenance. A shelf 25 is fixedly connected to the lower end of the tray 1 for placing tools. A battery 26 is installed inside the shelf 25. The lamps 24 are electrically connected to the battery 26.

[0035] The working principle of a photovoltaic power station operation and maintenance device in this embodiment is as follows: When in use, the device is equipped with ventilation holes 9 and air vents 10. When the back of the worker is against the backrest 4, the ventilation holes 9 and air vents 10 work together to improve the airflow efficiency between the backrest 4 and the worker's back, thereby improving back comfort. The backrest 4 is rotated and lifted, and the support plate 6 is pulled out. The free end of the support plate 6 is then placed against the appropriate position of the locking block 8, so that the backrest 4 and the support plate 1 form an angle. The worker then lies on the support plate 1 and the backrest 4, which facilitates the inspection and maintenance of lines at different heights on the back of the photovoltaic panel.

[0036] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
