[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0034] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the utility model, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of the features. In addition, if "and / or" or "and / or" appears in the full text, its meaning includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or solutions that satisfy both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0035] The utility model proposes a protective device for a photovoltaic power station. The photovoltaic power station includes a bracket and a photovoltaic component module installed on the bracket. The photovoltaic component module includes one or more photovoltaic components. The photovoltaic component module includes a lower side portion and an upper side portion that are relatively arranged. The photovoltaic component is arranged upward from the lower side portion to the upper side portion, and the protective device is arranged close to the lower side portion.

[0036] See also Figures 1 to 8 In one embodiment of the utility model, the protective device 100 includes a mounting member 1 and a protective assembly 2; the mounting member 1 is connected to the bracket 300 and extends in a direction away from the bracket 300; the protective assembly 2 includes a first stopper 21, the first stopper 21 is installed on the mounting member 1, and the upper edge of the lower side is defined as the first edge 4, and the upper surface of the first stopper 21 is located above the first edge 4.

[0037] In the related art, photovoltaic modules are usually installed in relatively open places. In order to avoid being blocked and obtain better lighting, common photovoltaic modules are installed on the roof through brackets. Photovoltaic modules are generally installed at an angle. In winter, the snow on the photovoltaic modules will slide down and may cause damage to people or objects below.

[0038] In the technical solution of the utility model, a photovoltaic module is installed on the bracket 300, the mounting member 1 is connected to the bracket 300, and extends outward beyond the lower side of the photovoltaic module. The protective component 2 includes a first stopper 21, and the first stopper 21 is installed on the mounting member 1. The upper surface of the first stopper 21 is located above the first edge 4. The photovoltaic module 400 is tilted relative to the bracket 300. The snow on the upper surface of the photovoltaic module module will slide toward the position of the first stopper 21. The first stopper 21 can come into contact with the snow sliding down the upper surface of the photovoltaic module module to reduce the speed of the snow sliding down and the impact force of the snow. The snow is then cut into a plurality of small pieces. This arrangement can make the volume of the falling snow smaller and the impact force lower, so as to reduce the damage of the falling snow to people and objects. It can also block part of the snow and reduce the amount of falling snow. When maintaining and installing the photovoltaic module, if materials or tools slide down, the first stopper 21 can also play a blocking role to prevent the tools and materials from falling and causing danger. At the same time, it can also prevent the staff from sliding off the photovoltaic module.

[0039] In one embodiment, one or more mounting members 1 are provided, and the extension direction of the photovoltaic component module on the lower side is defined as a first direction. The first stopper 21 is extended along the first direction. When multiple mounting members 1 are provided, the multiple mounting members 1 are spaced apart along the first direction, and the first stopper 21 is connected to each mounting member 1.

[0040] Specifically, a photovoltaic module is provided on the bracket 300. Since the area of ​​the photovoltaic module is large, more mounting members 1 are required to install the protective assembly 2. Multiple mounting members 1 are spaced apart along the first direction. The multiple mounting members 1 are all connected to the bracket 300. The first stopper 21 extends along the first direction, that is, the length of the first stopper 21 is long enough to cover all photovoltaic modules 400. The multiple mounting members 1 are all connected to the first stopper 21. Such a setting can increase the installation stability of the first stopper 21, prevent the first stopper 21 from being unstable in installation and causing the blocking effect of snow to deteriorate, and prevent the first stopper 21 from falling down due to excessive impact of snow. In some other embodiments, there are multiple first stops, and the multiple first stops are spaced apart along the edge of the photovoltaic module, and the first stops are connected to the mounting members one by one.

[0041] In one embodiment, the protection component 2 includes a second stopper 22 , which is installed on the first stopper 21 and is located between the photovoltaic component module and the first stopper 21 . The second stopper 22 is spaced apart from the photovoltaic component module.

[0042] Specifically, a second stopper 22 is provided between the first stopper 21 and the photovoltaic module. There is a certain gap between the second stopper 22 and the photovoltaic module. The second stopper 22 is used to collide with the snow or ice-snow mixture sliding down from the upper surface of the photovoltaic module. The gap between the second stopper 22 and the photovoltaic module can allow some small snow to pass through. With this arrangement, the second stopper 22 can break the large volume of snow or ice-snow mixture into small pieces before falling. In this way, when the falling snow collides with an object or a person, the damage to the person or the object can be reduced, and there will not be a large amount of snow accumulated at the edge of the photovoltaic module, causing excessive force there, thereby ensuring the service life of the photovoltaic module 400 and the protective component 2. In some other embodiments, one end of the second stopper abuts against the edge of the photovoltaic module.

[0043] In one embodiment, a plurality of second stoppers 22 are provided, and the plurality of second stoppers 22 are evenly spaced apart along the extending direction of the first stopper 21 .

[0044] Specifically, in the first direction, a plurality of second stops 22 are distributed, and each of the plurality of second stops 22 can break up the snow. Such a configuration can increase the working area of ​​the protective component 2 for breaking up the snow, and break up as much snow as possible that slides down from the photovoltaic component module, so as to reduce the possibility of damage to people or objects caused by falling snow.

[0045] In one embodiment, a plurality of mounting holes 211 are provided on the first stopper 21, and the plurality of mounting holes 211 are spaced apart along the first direction. A second stopper 22 is detachably mounted on a mounting hole 211, and an abutment plate 221 is protrudingly provided at one end of the second stopper 22. The abutment plate 221 is arranged at an angle to the second stopper 22, and the abutment plate 221 is used to abut against the side wall of the first stopper 21.

[0046] Specifically, the first stopper 21 is provided with a plurality of waist-shaped holes, which are evenly spaced along the length direction of the first stopper 21. A bolt is passed through the second stopper 22, which is threadedly connected with a nut after passing through the mounting hole 211. After the bolt is tightened, the second stopper 22 is pressed against the first stopper 21. An abutment plate 221 is provided at the end of the second stopper 22, which is tightly attached to the top wall of the first stopper 21. The abutment plate 221 can prevent the second stopper 22 from rotating relative to the first stopper 21. This arrangement can prevent the second stopper 22 from rotating along the bolt during use, resulting in the situation that the second stopper 22 is offset and cannot break the snow, and is also convenient for the maintenance and replacement of the second stopper 22. In some other embodiments, the second stopper is welded to the first stopper.

[0047] In one embodiment, the second stopper 22 is L-shaped, and the second stopper 22 includes an installation segment 222 and a blocking segment 223 connected at an angle. The installation segment 222 is installed on the first stopper 21, and the upper surface of the blocking segment 223 is located below the first edge 4. The blocking segment 223 is located between the first stopper 21 and the photovoltaic component module.

[0048] Specifically, in this embodiment, the second blocking member 22 is an L-shaped angle iron, the mounting section 222 is vertically arranged, and is detachably connected to the first blocking member 21, the angle between the blocking section 223 and the mounting section 222 is a right angle, the blocking section 223 is extended toward the bracket 300, and the blocking section 223 is located below the photovoltaic component module, the blocking section 223 is composed of a first sheet parallel to the ground and a second sheet perpendicular to the ground, the second sheet is used to cut the snow, and the second sheet is arranged perpendicular to the first sheet. This structure has high strength and better effect of cutting snow, the mounting section 222 is composed of a third sheet parallel to the first blocking member 21 and a fourth sheet perpendicular to the first blocking member 21, the third sheet abuts against the first blocking member 21, and the fourth sheet is perpendicular to the third sheet, which can improve the structural strength of the mounting section 222, and can ensure that when the snow falls, the blocking section 223 has a better effect of cutting the snow, thereby ensuring the use effect of the second blocking member 22. In some other embodiments, the second stopper may also be a U-shaped angle iron, and the heights of the two ends of the U-shaped angle iron are different. One end of the U-shaped angle iron close to the photovoltaic module is located below the photovoltaic module, and the other end extends to the upper end of the first stopper.

[0049] In one embodiment, the second stopper 22 is a mesh structure, and has a plurality of drop holes 23 for cutting snow.

[0050] Specifically, the mounting member 1 is an L-shaped profile, and a first stopper 21 is installed on the mounting member 1. The second stopper 22 is a mesh structure. When viewed from front to back, the second stopper 22 is L-shaped, and the upper end of the second stopper 22 is connected to the first stopper 21. The mesh structure has a plurality of drop holes 23. The drop holes 23 can be circular holes, polygonal holes, or irregular pattern holes, etc. With such an arrangement, when the accumulated snow slides from the upper surface of the photovoltaic module 400 to the mesh structure, the accumulated snow will be divided into a plurality of small fragments, and then fall to the bottom from the drop holes 23. In this way, when the falling snow collides with an object or a person, the damage to the person or object can be reduced.

[0051] Furthermore, the protective component 2 includes a plurality of clamping plates 24, which are L-shaped clamping plates. The clamping plates 24 are placed above the first stopper 21 and the second stopper 22. Bolts are passed through the clamping plates 24 and are screwed to the mounting member 1. The bolts are tightened to fix the clamping plates 24 to the mounting member 1, and can partially clamp the first stopper 21 and the second stopper 22 to the mounting member 1.

[0052] In one embodiment, the second stopper 22 is U-shaped, and the second stopper 22 has a first end and a second end. The first end is arranged close to the bracket, and the second end is far away from the bracket. In the vertical direction, the upper surface of the second end is higher than the upper surface of the first end, and the second end is connected to the first stopper 21.

[0053] Specifically, the end of the second stopper 22 close to the photovoltaic module is lower than the upper surface of the photovoltaic module. This arrangement can reduce the gap between the second stopper 22 and the photovoltaic module, preventing large snow or ice-snow mixture from falling from the gap, thereby reducing the occurrence of snow hitting objects or people. At the same time, the U-shaped second stopper 22 is longer, and the tail ends of multiple second stoppers 22 are commonly connected to a first stopper 21, so that more drop holes 23 can be formed, further improving the blocking and segmentation effect of the protective component 2 on snow or ice-snow mixture. In some other embodiments, the second stopper is L-shaped, and the blocking portion is formed at a higher end of the second stopper.

[0054] In one embodiment, the first stopper 21 and the second stopper 22 enclose a flow groove 212 , and the flow groove 212 extends along the first direction.

[0055] Specifically, the first stopper 21 and the second stopper 22 are in the shape of long strips, which are together enclosed to form a flow groove 212. The flow groove 212 is extended along the first direction. The first stopper 21 is the groove side wall of the flow groove 212, which is used to prevent snow from falling from the edge of the photovoltaic component module. A sewer pipe is connected to the groove mouth of the flow groove 212. After the snow is melted into water in the flow groove 212, it can be discharged to the ground through the sewer pipe. This arrangement can prevent the falling of snow and avoid people or objects from being hit.

[0056] In one embodiment, the mounting member 1 includes a first connecting segment 11 and a second connecting segment 12 connected at an angle, the first connecting segment 11 is connected to the bracket 300 , the second connecting segment 12 extends in a direction away from the first connecting segment 11 , and the first stopper 21 is mounted on the second connecting segment 12 .

[0057] Specifically, the angle between the first connecting section 11 and the second connecting section 12 is a right angle, that is, the first connecting section 11 and the second connecting section 12 are connected together in an L shape, the second connecting section 12 extends upward and extends beyond the upper surface of the lowest photovoltaic component 400, the first connecting section 11 and the second connecting section 12 are both profiles, the first connecting section 11 and the second connecting section 12 are detachably connected, the first stopper 21 is installed on the side of the second connecting section 12 facing the photovoltaic component module, the first connecting section 11 and the second connecting section 12 can adjust the length according to the actual installation situation, and the profile has a connecting structure, which is convenient for the installation of the first stopper 21, and also convenient for connecting the mounting member 1 to the bracket 300. In some other embodiments, the first connecting section and the second connecting section are integrally formed.

[0058] In one embodiment, the protective device 100 includes a support member, one end of which is connected to the position where the bracket 300 is installed, and the other end of which is connected to the bottom of the mounting member 1 , and the support member is used to support the mounting member 1 .

[0059] Specifically, in this embodiment, the bracket 300 is installed on the roof, so one end of the support member is connected to the roof, and the other end of the support member is connected to the bottom of the mounting member 1, so that the support member is inclined to support the mounting member 1. This arrangement can increase the supporting performance of the mounting member 1, ensure the installation stability of the protection component 2, and increase the supporting strength of the protection component 2 to prevent the protection component 2 from being damaged by the impact of snow when the snow is too heavy. In some other embodiments, one end of the support member is connected to the bracket, and the other end is connected to the mounting member.

[0060] In one embodiment, the projection of the first stopper 21 in any direction does not overlap with the photovoltaic assembly module.

[0061] Specifically, when sunlight shines on the first barrier 21, the first barrier 21 will not be projected onto the upper surface of any photovoltaic module 400, that is, the first barrier 21 will not block the upper surface of the photovoltaic module 400. This arrangement can ensure that the working efficiency of the photovoltaic module 400 is not affected.
