[0003] The safety protection device for photovoltaic construction mainly includes a work platform and an assembly mechanism (such as a workbench, a fixed rod, a fixed part, etc., which is used to provide a stable work platform and firmly install), personal safety protection equipment (such as a safety belt, a fall arrestor, a non-slip mat, non-slip shoes, a welding mask, etc., which is used to protect construction personnel from high-altitude falling, slipping, head injury, etc.), and construction site safety protection facilities (such as a safety net, a guardrail, a warning sign, etc., which is used to prevent construction personnel or objects from falling and to warn potential dangers).

[0004] In the construction site of installing photovoltaic panels, a plurality of steel pipes are welded into a certain frame. When a welder places a photovoltaic panel on the steel frame and performs electric welding, a handheld welding mask is generally used, which can only be used with one hand, reducing work efficiency. Some construction sites also provide head-mounted welding masks, but the dust is generally large in the construction site, and dust will adhere to the observation mirror after a long time of use. Due to the reflective design of the welding mask, the worker needs to wear it repeatedly when welding, otherwise it will affect other construction, and the use process is relatively troublesome, so a safety protection device for photovoltaic construction is proposed.

DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0026] Embodiment one

[0027] As Figures 1-5 shown, the utility model provides a kind of safety protection device for photovoltaic construction, including adjustable head prison 1 and electric welding mask 3, electric welding mask 3 is movably connected between adjustable head prison 1, and electric welding mask 3 is provided with protective cleaning assembly, and protective cleaning assembly includes cleaning block 13 and reflector 10, the outside of electric welding mask 3 is fixedly connected with fixed hook 4 symmetrically, and adjustable head prison 1 is movably connected with adjusting knob 5 on the side away from electric welding mask 3;

[0028] The outside of electric welding mask 3 is fixedly connected with fixed block 6 symmetrically, and the outside of adjustable head prison 1 is movably connected with rotating block 9 symmetrically, and fixed block 6 is fixedly connected between rotating block 9;

[0029] The outer side of the welding mask 3 is fixedly connected to an upper support plate 2 and a lower support plate 7. The upper support plate 2 and the lower support plate 7 are slidably connected to the cleaning block 13. The cleaning block 13 is slidably connected to the welding mask 3.

[0030] A groove 11 is provided on the side of the upper support plate 2 near the lower support plate 7. A sliding strip 17 is fixedly connected to the inner side of the groove 11, and the sliding strip 17 is slidably connected to the reflector 10.

[0031] In this embodiment, during use, the adjustable headgear 1 is worn on the worker's head, and the tightness is adjusted by rotating the adjustment knob 5. The initial position of the cleaning block 13 is close to the storage cylinder 8. Then, when the worker performs electric welding, the cleaning block 13 is pulled towards the fixed hook 4. The sliding strip 17 fixedly connected to the inner side of the groove 11 guides the movement of the cleaning block 13. The movement of the cleaning block 13 drives the movement of the fixed plate 12. Since the fixed plate 12 is fixedly connected to the reflector 10, the movement of the fixed plate 12 drives the reflector 10 to be pulled out from the inside of the storage cylinder 8. At the same time, the reflector 10 extending out of the outside of the storage cylinder 8 covers the electric welding mask 3 to prevent the arc light generated by electric welding from damaging the worker's eyes.

[0032] As the reflector 10 extends, it simultaneously causes the coil spring 16 inside the storage cylinder 8 to retract. When the cleaning block 13 moves close to the fixing hook 4, the symmetrically arranged fixing hook 4 is used to lock the fixing plate 12, thus achieving fixation. During the above process, the electric welding operation will generate strong arc light, which is extremely harmful to the worker's eyes. By setting the reflector 10 to cover the lens of the electric welding mask 3, the reflector can effectively block the strong arc light generated during electric welding and protect the worker's eyes from harm.

[0033] Example 2

[0034] like Figures 1-5 As shown, based on Embodiment 1, a fixing plate 12 is fixedly connected to the side of the cleaning block 13 near the fixing hook 4. The fixing plate 12 is fixedly connected to the reflector 10, and the two fixing hooks 4 are movably connected to the fixing plate 12.

[0035] A support block 14 is fixedly connected to the side of the welding mask 3 away from the fixing hook 4, and a storage cylinder 8 is fixedly connected between the two support blocks 14.

[0036] A rotating rod 15 is rotatably connected between the two fixed hooks 4, and the rotating rod 15 is located inside the support block 14;

[0037] A coil spring 16 is fixedly connected to the outside of the rotating rod 15. The coil spring 16 is fixedly connected to the reflector 10, and the reflector 10 is slidably connected to the storage cylinder 8.

[0038] In the embodiment, when the worker is working, the cleaning block 13 is in close contact with the welding mask 3, and the reflective sheet 10 is moved by the movement of the cleaning block 13. The reflective sheet 10 can shield the lens of the welding mask 3, and the cleaning block 13 can scrape the lens of the welding mask 3 and remove the dust attached to the lens when the cleaning block 13 moves to the fixing hook 4, thereby improving the observation effect of the welding mask 3. After the welding is completed, the contact between the two fixing hooks 4 and the fixing plate 12 is released. At this time, the cleaning block 13 is pulled to move the reflective sheet 10 to the direction of the storage cylinder 8 under the action of the disc spring 16. Thus, the coverage of the reflective sheet 10 on the welding mask 3 is released, and the brightness of the line of sight of the worker can be restored.

[0039] Then, the welding mask 3 is turned to the direction of the adjusting knob 5, so that the welding mask 3 covers the head of the worker to provide sunshade. The welding mask 3 does not need to be removed and can be used at any time. In the above process, the operation of the protective cleaning assembly is convenient, and the maintenance is simple. The worker can easily operate the reflective sheet and the cleaning block, and the welding mask can always maintain a good working state.

[0040] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
