Description

Technical Field

[0001] This utility model relates to the field of safety protection equipment technology, and in particular to a retractable fence applied to photovoltaic rooftops. Background Technology

[0002] The factory buildings commonly used in today's industrial photovoltaic projects are concrete roofs or corrugated steel roofs. Due to the material and structure of corrugated steel roofs, it is difficult to add parapet walls. Parapet walls are set around the edge of the roof to protect workers from slipping off the roof when they are working on it. In addition, since photovoltaic modules are installed inside the factory building, and these modules need to receive light to carry out production operations, the fences added to the roof must minimize the shading area while ensuring the safety of workers, so as not to reduce the efficiency of the photovoltaic panels' light-receiving area.

[0003] In conclusion, developing a retractable fence with a small shading area that can protect the safety of workers is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] The purpose of this invention is to provide a retractable fence for photovoltaic rooftops, solving the technical problem of the lack of safety protection facilities on the roofs of photovoltaic factories.

[0005] To achieve the above objectives, this utility model provides a telescopic fence for photovoltaic rooftops, including two sliding guide rails, with a fence assembly slidably disposed between the two sliding guide rails. The fence assembly can extend and retract along the length of the sliding guide rails. One end of the fence assembly is locked, and the other end is fixedly connected to a driving component, which is used to extend and retract the fence assembly.

[0006] The fence assembly includes a fixed post, a support base, a support post, and the fence body;

[0007] The support base is slidably disposed between each sliding guide rail, and the support base is perpendicular to each sliding guide rail. A fixing rod is fixedly connected to the sliding guide rail along the axis of symmetry in the thickness direction.

[0008] The sliding guide rails are equipped with a number of identical fixed rods and sliding guide rails. Each fixed rod has a support rod symmetrically arranged on both sides. The two ends of each support rod are connected to the fixed rod and the support base respectively. The fence body is provided between adjacent fixed rods.

[0009] Preferably, the fence body includes several connecting rods, each connected by a connecting shaft. The connecting shaft passes through the two ends and the midpoint of the connecting rod, and each connecting shaft passes through two connecting rods. The connecting rods cooperate to form several rhomboid structures, and each connecting rod can rotate around the vertices of each rhomboid structure.

[0010] Preferably, there are two sliding guide rails, which are arranged in parallel. Each sliding guide rail has a sliding groove on its opposite side, and a roller is slidably installed in the sliding groove.

[0011] Preferably, the support base is connected to fixed cylinders at both ends, the axis of the fixed cylinders is parallel to the length direction of the support base, and the fixed cylinders are inserted into the rollers, so that the support base is slidably connected to the sliding guide rail.

[0012] Preferably, the sliding guide rail is fixedly connected to the external environment by a clamp. The clamp is provided with a snap-fit ​​groove and a mounting plate. The snap-fit ​​groove is set perpendicularly to the mounting plate, the mounting plate is parallel to the support base, and a fixing member is set vertically on the mounting plate. The fixing member connects the sliding guide rail to the mounting plate, and the snap-fit ​​groove is connected to the snap-fit ​​member to fix the position of the sliding guide rail.

[0013] Preferably, the bottom of the drive component is provided with a rolling shaft, which is connected to the output shaft of the drive component. Both ends of the rolling shaft can be connected to rollers, which move within the sliding groove.

[0014] Preferably, the sidewall of the drive component is connected to the fixed rod located at the end, and each fence body is connected to the fixed rod at both ends of the fence body through a connector, with the connectors symmetrically distributed on both sides of the end of the fence body.

[0015] Preferably, the fixing rod, the support base, and the support rod are all specifically square tubes.

[0016] Preferably, the length of the fence body in its maximum stretched state is ten times the length in its minimum contracted state.

[0017] Compared to the aforementioned background technology, the telescopic fence provided by this utility model includes: a sliding guide rail, within which a fence assembly is slidably mounted, wherein one end of the fence assembly is fixed and the other end is slidable, and the fence assembly can extend and retract along the length of the sliding guide rail. The fence assembly includes a support base, which is slidably mounted between two sliding guide rails and is perpendicular to each sliding guide rail. The support base slides along the length of the sliding guide rails. A fixed rod is fixedly connected to each sliding guide rail, and the fixed rod is perpendicular to the support base. Support rods are symmetrically mounted on both sides of the fixed rod, with each end of the support rod connected to the side wall of the fixed rod and the top surface of the support base, respectively. The two support rods are set at a certain angle, and all support rods, the fixed rod, and the support base are located on the same plane. The support base drives the fixed rods to move. The support rods on both sides of the fixed rod ensure the stability of the fixed rod's movement, and the fence body is connected between each fixed rod. The fence body is a telescopic mesh structure. One movable end of the fence component is fixedly connected to a driving component, which can also move between the sliding guide rails. When workers need to perform high-altitude work on the roof, the driving component is activated. The driving component moves along the sliding guide rail and pulls the fence component connected to it. One end of the fence component is fixed and the other end moves, so the fence component is stretched. When the driving component moves to the end of the sliding guide rail, the fence component is set up around the edge of the roof, providing protection for the workers. Moreover, after stretching, only the distribution density of the fence components changes, and the side area of ​​the fence components themselves does not change. Therefore, the area of ​​the shadow cast by the fence components during the stretching process remains unchanged.

[0018] This utility model provides a retractable fence for photovoltaic rooftops, which provides safety protection for workers while reducing the shaded area created by the fence and improving the light utilization rate of photovoltaic modules. Attached Figure Description

Detailed Implementation

[0026] 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.

[0027] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] This invention provides a telescopic fence for photovoltaic rooftops. The telescopic fence includes sliding guide rails 1, which are arranged parallel to each other. A fence assembly is slidably disposed between the sliding guide rails 1, allowing the fence assembly to move along the length of the sliding guide rails 1. Furthermore, the fence assembly can extend or retract by changing the connection state of its components. The extension / retraction direction of the fence assembly is the same as the sliding direction, meaning the fence assembly can extend or retract along the length of the sliding guide rails. One side of the fence assembly located at the end of the sliding guide rail is locked, while the other side is fixedly connected to a driving component 2. The driving component 2 can also move along the length of the sliding guide rails 1 between the sliding guide rails 1, driving the fence assembly connected to it. One end of the fence assembly is locked. When one end is fixed and the other end moves, the distance between the two ends of the fence component increases, and the fence component is stretched, so that the edge of the roof has a blocking device, providing a safe construction environment for workers. During the stretching process, only the connection state of each component of the fence component changes. That is to say, the area of ​​the side wall of the fence component remains unchanged during the stretching process. The shadow area produced by the fence component in the compressed state is small. Although the length of the fence component changes after stretching, the resulting shading shadow is the same as that in the compressed state. The fence component provided by this utility model greatly reduces the impact of adding a protective wall to the roof on the light area while providing a safe construction environment for workers, ensuring that the photovoltaic module still has a large light area utilization rate.

[0029] Please refer to the instruction manual appendix. Figure 1 To be continued Figure 4 The fence assembly includes a fixed rod 3, a support base 4, a support rod 5, and a fence body 6. The support base 4 is located at the bottom of the fence assembly and is used to support the support rod 5, the fixed rod 3, and the fence body 6. There can be two sliding rails 1, each arranged parallel to the other. The support base 4 is slidably positioned between the two sliding rails 1 and is perpendicular to them. The support base 4 has a fixed rod 3 located at the midpoint of the support base 4 and perpendicular to it. A support rod 5 is also obliquely positioned between the fixed rod 3 and the support base 4, symmetrically distributed on both sides of the fixed rod 3. The support base 4, support rod 5, and fixed rod 3 are fixedly connected as a single unit. The connected support base 4 and the two support rods 5... Forming an isosceles acute triangle, the support base 4, support rod 5, and fixed rod 3 are all located on the same plane. When the assembly is placed between the sliding guide rails, the support base 4 connected to the sliding guide rails drives the assembly to slide. The support rods 5 on both sides of the fixed rod 3 enhance the stability of the fixed rod 3 and prevent the fixed rod 3 from tilting during movement, which would cause the connection between the fixed rod 3 and the support to be subjected to a large load and damage the fence assembly. Furthermore, there are several assembled assemblies distributed between the sliding guide rails 1 after connection. Each assembled assembly can slide independently. The fence body 6 is connected between the assembled assemblies. The fence body 6 is connected to two adjacent fixed rods 3. The fixed rods 3 move and stretch the fence body 6.

[0030] Furthermore, the fence body 6 is composed of several connecting rods 61, each paired together and rotatably connected by a connecting shaft 62. Each connecting rod 61 has three connecting holes: two connecting holes symmetrically distributed at both ends and one connecting hole at the midpoint. Two connecting rods 61 are arranged crosswise, their midpoint connecting holes aligned, and the connecting shaft 62 is inserted through them, forming an X-shape. Finally, the connecting holes at the ends of one connecting rod 61 are aligned with the connecting holes at the ends of another connecting rod 61. Similarly, multiple X-shaped assemblies are connected via connecting shaft 62, and each connecting rod 61 can rotate around connecting shaft 62. The fence body 6 formed by the combination of connecting rods 61 is in the form of several connected rhombuses. The rotation axis of each connecting rod 61 is the vertex of the rhombus. Due to the instability of the rhombus, stretching the vertices on both sides of the rhombus makes the length of the rhombus along the sliding direction approach the length of the two connecting rods 61, while compressing the vertices on both sides of the rhombus makes the length of the rhombus along the sliding direction approach the thickness of the two connecting rods 61. By changing the shape of each rhombus in the fence body 6, the stretching and compression of the fence components can be achieved.

[0031] Furthermore, during the stretching process of the fence assembly, only the included angle between the connecting rods 61 and the density of the distribution of the connecting rods 61 are changed. The spacing between each fixed rod 3 is also changed. The overall area of ​​the fence assembly is fixed throughout the stretching process. Under sunlight, the projected area on the roof is also fixed. The fence assembly causes only a small amount of shading in the compressed state. Similarly, it still causes a small amount of shading in the stretched state, ensuring that the photovoltaic module has a high light utilization rate.

[0032] It should be noted that sliding grooves are provided on the opposite sides of the two sliding guide rails 1. The extension direction of the sliding grooves is the same as the length direction of the sliding guide rails 1, and the sliding grooves pass through both ends of the sliding guide rails 1. Rollers 7 are rotatably installed in the sliding guide rails 1, and the rotation axis of the rollers 7 points towards the opening of the sliding grooves. Furthermore, the fixing rods 3, support seats 4, and support rods 5 can all be made of galvanized steel square tubes to ensure that the fence components have sufficient strength and that the telescopic fence has reliable safety after installation. In addition, fixed cylinders are provided at both ends of the support seats 4. 41. The axis of the fixed cylinder 41 is parallel to the length direction of the support base 4. The diameter of the fixed cylinder 41 is smaller than the opening diameter of the sliding groove. The fixed cylinder 41 can extend into the sliding groove and cooperate with the roller 7 in the sliding groove, so that the support base 4 can slide between the sliding guide rails 1. In addition, the diameter of the roller 7 is also larger than the opening diameter of the sliding groove. That is to say, the roller 7 is locked inside the sliding groove. The roller 7 only slides along the extension direction of the sliding groove. The roller 7 will not fall off the sliding guide rail 1, which further ensures the reliability of the telescopic fence.

[0033] The driving component 2 is a part used to realize the stretching and compression of the fence assembly. It is connected to the fixed rod 3 located at the end of the stretching assembly. The connection method can be welding to ensure that the fixed rod 3 can move together with the driving component 2. The driving component 2 and the support base 4 are set together between the two sliding guide rails 1. The bottom of the driving component 2 is provided with a rolling shaft 21, which is connected to the output shaft of the engine inside the driving component 2. The rolling shaft 21 is also inserted into the sliding groove and connected to the rollers 7 on both sides. In order to make the driving component 2 move smoothly, specifically, there are two rolling shafts 21, which are arranged in parallel. In addition, the fence body 6 is provided with connectors 9 on both sides of the end. The connectors 9 connect the fence body 6 to the fixed rod 3.

[0034] To ensure the telescopic fence can be fixed to the target site, a clamp 8 is provided below the sliding guide rail 1. The clamp 8 includes a mounting plate 81 for mounting the sliding guide rail 1 and a snap-fit ​​groove 82 for connecting to a pre-set snap-fit ​​component on the external site. The mounting plate 81 is parallel to the support base 4. The mounting plate 81 and the snap-fit ​​groove 82 are vertically connected by a fastener 83. After the sliding guide rail 1 is placed on the mounting plate 81, the fastener 83 is inserted between the two to fix the sliding guide rail 1 to the clamp 8. Then, the snap-fit ​​groove 82 of the clamp 8 is connected to the snap-fit ​​component, thus setting the telescopic fence on the target site.

[0035] In one embodiment of this utility model, the sliding guide rail 1 is fixed on the clamp 8. The clamp 8 installs the sliding guide rail 1 as a whole in a preset scene through the snap-fit ​​groove 82. The driving component 2 between the sliding rails is activated, and the driving component 2 moves towards one end of the sliding guide rail 1. The fixed rod 3 connected to the driving component 2 moves accordingly. Since the fixed rod 3 at the end away from the driving component 2 is locked, when the driving component 2 pulls the fixed rod 3, the fixed rod 3 pulls the fence body 6 and other fixed rods 3 adjacent to the fence body. The bottom of the fixed rod 3 is provided with a support seat 4 that can slide relative to the sliding guide rail. The support seat 4 drives the fixed rod 3 connected to it to move. In this way, the distance between each fixed rod 3 gradually increases, and the fence body 6 connected between each fixed rod 3 deforms. The fence body 6 is stretched along the direction of the sliding guide rail 1, and the length of the telescopic fence increases, so that the edge of the construction site has protective measures. The support rods 5 set on both sides of the fixed rod 3 further enhance the reliability of the telescopic fence.

[0037] This article uses specific examples to illustrate the principles and implementation methods of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principles of this utility model, and these improvements and modifications also fall within the protection scope of this utility model.
