[0010] 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.

[0011] Please see Figure 1-4 .

[0012] Example 1 A safety protection device for the construction of a rooftop photovoltaic power station includes an installation mechanism 2 for fixing to both sides of the top of a roof 1 and a protective net mechanism 3 connected between the two installation mechanisms 2. The protective net mechanism 3 includes two columns 31 fixed to the two installation mechanisms 2 and a protective net 35 connected between the two columns 31. Specifically, after being fixed by the installation mechanism 2, the columns 31 can be vertically erected at both ends of the bottom edge of the roof 1. By setting the protective net 35 between the two columns 31, a protective structure can be formed along the length of the bottom edge of the roof 1 to prevent construction workers from falling from the bottom edge of the roof 1.

[0013] Furthermore, to make the protective device applicable to roofs 1 of different lengths, one column 31 is rotatably connected to a rotating rod 34, and another column 31 is detachably fixed with a movable rod 32. One end of the protective net 35 is wound and connected to the rotating rod 34, and the other end of the protective net 35 is fixedly connected to the movable rod 32. By winding and connecting one end of the protective net 35 to the rotating rod 34 and fixing the other end to the movable rod 32, during installation, two sets of installation mechanisms 2 can be fixed on both sides of the roof 1 first, then the column 31 with the rotating rod 34 is fixed to one set of installation mechanisms 2, and then the column 31 with the movable rod 32 is fixed to the other set of installation mechanisms 2. During installation, the length of the protective net 35 can be adjusted by rotating the rotating rod 34, so that the length of the protective net 35 can be adapted to the length of the roof 1. Compared with existing technologies such as CN223190096U, a roof photovoltaic power station construction safety protection device, it has better adjustment capabilities.

[0014] The upper and lower ends of the column 31 are integrally formed with a top plate and a bottom plate, respectively, so that the column 31 forms a U-shaped structure. The upper and lower ends of the movable rod 32 are in contact with the top plate and the bottom plate, respectively, and both the upper and lower ends of the movable rod 32 are provided with threaded holes 321. The top plate and the bottom plate are connected with connecting bolts 5 corresponding to the threaded holes 321. When installing the movable rod 32, the protective net 35 is first stretched by moving the movable rod 32. Then, the upper and lower ends of the movable rod 32 are placed between the top plate and the bottom plate of the column 31, respectively. Then, the two connecting bolts 5 are threaded through the top plate and the bottom plate and threaded to the threaded holes 321 at the upper and lower ends of the movable rod 32.

[0015] In this embodiment, the installation mechanism 2 includes a channel steel 21, which is horizontally fixed to the side of the roof 1 by expansion bolts 22 to ensure a good fixing effect. The lower end of the column 31 is provided with a plug-in block 33 that can form a plug-in fit with the end of the channel steel 21. The plug-in block 33 and the channel steel 21 are connected by an installation bolt 4. After the channel steel 21 is fixed, the lower end of the column 31 is inserted into one end of the channel steel 21 through the plug-in block 33, and then the plug-in block 33 is locked by the installation bolt 4.

[0016] Example 2 A safety protection device for the construction of a rooftop photovoltaic power station is similar in structure to that of Embodiment 1, except that the protective net 35 itself has a certain deformation capability, which makes it easy for the gap between the bottom of the protective net 35 and the bottom edge of the roof 1 to be widened. This makes it easy for construction workers to fall through the gap between the bottom of the protective net 35 and the bottom edge of the roof 1 when they fall. In order to solve the above problem, the protective device also includes a tensioning mechanism 6 connected between the lower ends of the two columns 31 for tightening the bottom edge of the protective net 35 to the bottom edge of the roof 1.

[0017] In this embodiment, the tensioning mechanism 6 includes a steel wire rope 62 connected between the rotating rod 34 and the movable rod 32. A connecting ring 63 is fixed along the length direction of the bottom edge of the protective net 35. The connecting ring 63 and the steel wire rope 62 are connected by a tensioning member 61. It can be understood that the steel wire rope 62 does not have the ability to deform in the axial direction. The steel wire rope 62 is connected between the rotating rod 34 and the movable rod 32, and the tensioning member 61 tightens the steel wire rope 62 and the connecting ring 63, so that the bottom of the protective net 35 is tightly connected to the steel wire rope 62 and fits tightly against the bottom edge of the roof 1, preventing the gap between the bottom of the protective net 35 and the bottom edge of the roof 1 from widening.

[0018] In some specific embodiments of this example, the tensioning member 61 can be a thin iron wire or a turnbuckle tightener.

[0019] To facilitate adjustment of the length of the wire rope 62, a wire rope winding mechanism 64 is connected to the bottom end of the rotating rod 34.

[0020] In this embodiment, the wire rope winding mechanism 64 includes a winding wheel 641 fixed to the lower end of the rotating rod 34. One end of the wire rope 641 is wound and connected to the winding wheel 641, and the other end of the wire rope 641 is fixedly connected to the movable rod 32. The column 31 is threaded with a fixing bolt 643. The winding wheel 641 is provided with a fixing hole 642 corresponding to the fixing bolt 643. The winding wheel 641 is used to wind and unwind the wire rope 641, thereby adjusting the length of the wire rope 641. When it is necessary to fix the length of the wire rope 641, the fixing bolt 643 can be inserted into the fixing hole 642. The number of fixing holes 642 is at least 4, and they are evenly distributed around the center of the winding wheel 641.

[0021] It is understood that in some embodiments of this example, the tensioning mechanism 6 may also be additionally added to the upper side of the protective net 35, and the upper side of the protective net 35 may be tensioned in the same way as the tensioning mechanism 6 described above, so as to prevent the upper side of the protective net 35 from deforming when construction workers fall on the surface of the protective net 35.

[0022] In summary, this utility model aims to achieve efficient and safe protection during the construction of rooftop photovoltaic power stations. By setting up an installation mechanism 2 that can be fixed to the roof 1 and a protective net mechanism 3 connected therebetween, the length of the protective net 35 can be adjusted by using a rotating rod 34 and a movable rod 32 to adapt to roofs of different lengths. At the same time, in response to the problem that gaps may appear between the bottom of the protective net 35 and the bottom edge of the roof 1, which may lead to the risk of falling, a tensioning mechanism 6 is added to tightly pull the bottom edge of the protective net 35 to the bottom edge of the roof 1, thus ensuring the safety of construction personnel in all aspects.

The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.
