Description

Technical Field

[0001] This utility model relates to the field of rooftop photovoltaic engineering technology, and in particular to a protective net for rooftop photovoltaic engineering. Background Technology

[0002] In recent years, driven by the national top-level design requirements for dual-carbon goals, my country's photovoltaic (PV) sector has experienced significant development. Rooftop PV, in particular, has seen rapid growth. Rooftop PV is a clean, environmentally friendly, and sustainable new energy source with broad development prospects. With technological advancements and cost reductions, rooftop PV will be more widely applied. However, the safety risks associated with rooftop PV, especially on sloping roofs made of corrugated steel sheets, are not to be underestimated. This increases the risk of workers falling from heights during construction and maintenance, necessitating the use of safety nets to protect workers.

[0003] Most existing protective nets for rooftop photovoltaic projects are formed by screws on the construction site, which makes the installation and dismantling process cumbersome and greatly affects construction efficiency. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that the installation and disassembly process of the existing technology is relatively cumbersome and affects the construction efficiency, and to propose a protective net for roof photovoltaic projects.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A protective net for a rooftop photovoltaic project includes a main body and two bases. Support columns are fixedly connected to the top of each base. A vertical column is fitted onto the outer surface of each support column. Two U-shaped clamps are snapped onto the outer surface of each vertical column. A rectangular frame is fixedly connected to the back of each U-shaped clamp. Four hanging plates are fixedly connected to the back of the main body of the protective net. The bottoms of the four hanging plates are respectively inserted into the four rectangular frames. A threaded sleeve is fixedly installed inside each support column. An adjusting screw is provided inside the threaded sleeve. A lifting seat is fixedly installed on the adjusting screw. A first ball bearing is provided inside the lifting seat. A fixed seat is movably installed above the lifting seat and fixed to the top of the vertical column. An oil can is fixedly installed at the upper end of each support column. A second ball bearing is movably installed in the oil outlet of the oil can and abuts against the inner wall of the vertical column.

[0007] Each of the two columns is provided with two limiting components, and the limiting components correspond one-to-one with the U-shaped card plate. The limiting components are used to limit the U-shaped card plate. The limiting components include two limiting rods that are slidably connected inside the U-shaped card plate. The column is provided with limiting holes that are adapted to the limiting rods. The ends of the two limiting rods that are close to each other are inserted into the limiting holes.

[0008] Preferably, the support column has a set of equally spaced threaded holes inside, and a first screw is slidably connected to the column, with one end of the first screw threaded into the inside of one of the threaded holes.

[0009] Preferably, each of the two limiting rods has a cylinder fixedly connected to its far ends, and a spring is fixedly connected inside each of the two cylinders. The ends of the two springs that are close to each other are fixedly connected to the outer surface of the U-shaped plate.

[0010] Preferably, the column is provided with a track groove that is adapted to the limiting rod, and the track groove is connected to the limiting hole.

[0011] Preferably, the interior of each of the two rectangular frames is threaded with a second screw, and one end of each of the two second screws is rotatably mounted with a clamping plate. The two clamping plates are slidably connected inside the two rectangular frames, and the two rectangular frames abut against the two hanging plates respectively.

[0012] Preferably, the base and the roof are connected by an adhesive to avoid the safety risks associated with welding or hot work.

[0013] Compared with the prior art, the present invention provides a protective net for rooftop photovoltaic projects, which has the following beneficial effects.

[0014] 1. This utility model eliminates the need for screws and external tools when installing the main body of the protective net, thereby effectively improving the efficiency of disassembly and assembly of the main body of the protective net and thus improving construction efficiency.

[0015] 2. This utility model, through the cooperation between the rectangular frame and the second screw, can further tighten and reinforce the main body of the protective net after the installation is completed, thereby effectively improving the stability of the main body of the protective net during use. By adjusting the cooperation between the screw, the threaded hole and the first screw, the height of the main body of the protective net can be adjusted according to specific needs.

[0016] 3. This utility model can effectively avoid hot work operations and prevent the fire risk of flammable and explosive materials in the factory.

[0017] 4. During the lifting and lowering process of the adjusting screw, the lifting seat and the fixed seat rotate and come into contact, which can reduce the friction on the top of the column. At the same time, when the column moves up and down along the support column, it will drive the second ball to rotate. After the second ball rotates, it will apply the lubricating oil in the oil can to the inner wall of the column, thereby reducing the friction between the column and the support column and extending the service life of the equipment.

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5 A protective net for rooftop photovoltaic projects includes a protective net body 6 and two bases 1. Support columns 2 are fixedly connected to the top of each base 1. Vertical columns 3 are fitted onto the outer surfaces of each support column 2. Two U-shaped clips 8 are snapped onto the outer surfaces of each vertical column 3. A rectangular frame 10 is fixedly connected to the back of each U-shaped clip 8. Four hanging plates 9 are fixedly connected to the back of the protective net body 6. The bottoms of the four hanging plates 9 are respectively inserted into the interiors of the four rectangular frames 10. A rectangular groove adapted to the support column 2 is opened inside the vertical column 3. After the restriction on the vertical column 3 is released, the vertical column 3 can slide up and down along the support column 2. The shape of the hanging plate 9 is right-angled, and the size of the hanging plate 9 is adapted to the inner cavity size of the rectangular frame 10.

[0028] Reference Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 A threaded sleeve 18 is fixedly installed inside the support column 2. An adjusting screw 13 is provided inside the threaded sleeve 18. A set of equally spaced threaded holes 4 are opened inside the support column 2. A first screw 5 is slidably connected to the column 3. One end of the first screw 5 is threaded into the inside of one of the threaded holes 4. After unscrewing the first screw 5 from the inside of the threaded hole 4, the restriction on the column 3 can be released. Then, the adjusting screw 13 can be rotated to make the column 3 slide up and down along the support column 2. When the column 3 slides to the specified height, the first screw 5 is screwed into the corresponding threaded hole 4 to limit the column 3. Thus, the height of the column 3 can be adjusted. By adjusting the height of the column 3, the height of the protective net body 6 can be adjusted.

[0029] Reference Figure 2 , Figure 3 and Figure 6 A lifting seat 15 is fixedly installed on the adjusting screw 13. The lifting seat 15 is provided with a first ball bearing 17. A fixed seat 14 is movably installed above the lifting seat 15 and is fixed to the top of the column 3. During the lifting and lowering process of the adjusting screw 13, the lifting seat 15 and the fixed seat 14 rotate and come into contact, which can reduce the friction on the top of the column 3.

[0030] Reference Figure 2 and Figure 6 An oil can 16 is fixedly installed on the upper end of the support column 2. A second ball bearing 19 is movably installed inside the oil outlet of the oil can 16 and abuts against the inner wall of the column 3. When the column 3 moves up and down along the support column 2, it will drive the second ball bearing 19 to rotate. After the second ball bearing 19 rotates, it will apply the lubricating oil in the oil can 16 to the inner wall of the column 3, thereby reducing the friction between the column 3 and the support column 2 and extending the service life of the equipment.

[0031] Reference Figure 1 , Figure 2 and Figure 4 Each of the two columns 3 is provided with two limiting components 7, and the limiting components 7 correspond one-to-one with the U-shaped clamping plates 8. The limiting components 7 are used to limit the U-shaped clamping plates 8. The limiting components 7 include two limiting rods 703 that are slidably connected inside the U-shaped clamping plates 8. The column 3 is provided with limiting holes 705 that are adapted to the limiting rods 703. The ends of the two limiting rods 703 that are close to each other are inserted into the limiting holes 705. After the ends of the two limiting rods 703 that are close to each other are inserted into the limiting holes 705, the U-shaped clamping plates 8 can be stably clamped onto the outer surface of the column 3.

[0032] Reference Figure 1 , Figure 3and Figure 4 Two limiting rods 703 are fixedly connected to cylinders 702 at their far ends. Springs 701 are fixedly connected inside the two cylinders 702. The ends of the two springs 701 that are close to each other are fixedly connected to the outer surface of the U-shaped clamping plate 8. When the cylinders 702 are pulled away from the U-shaped clamping plate 8, the limiting rods 703 can move accordingly and the springs 701 can be stretched.

[0033] Reference Figure 1 and Figure 3 The column 3 has a track groove 704 adapted to the limiting rod 703, and the track groove 704 is connected to the limiting hole 705. There are two track grooves 704, and the two track grooves 704 are symmetrical about the center point of the column 3. When installing the U-shaped clamping plate 8, firstly, the U-shaped clamping plate 8 is clamped onto the outer surface of the column 3, and the ends of the two limiting rods 703 that are close to each other are inserted into the two track grooves 704 respectively. At this time, the spring 701 is in a stretched state. Then, the U-shaped clamping plate 8 is pushed towards the column 3. After the U-shaped clamping plate 8 is pushed towards the column 3 to the maximum extent, the limiting rod 703 will be aligned with the limiting hole 705. At this time, under the action of spring 701, one end of limit rod 703 will be inserted into the inside of limit hole 705, thereby limiting the U-shaped card plate 8, and then the U-shaped card plate 8 will be installed relatively stably on the column 3. Then, the four hanging plates 9 are inserted into the inside of the four rectangular frames 10 respectively to complete the installation of the protective net body 6. No screws or external tools are needed in the entire installation process, which can effectively improve the construction efficiency. Similarly, when disassembling the U-shaped card plate 8, simply pull the cylinder 702 away from the column 3 to release the fixation of the U-shaped card plate 8, and then the U-shaped card plate 8 can be removed from the column 3.

[0034] Reference Figure 4 Both rectangular frames 10 are threaded with second screws 11 inside. One end of each second screw 11 is rotatably mounted with a clamping plate 12. The two clamping plates 12 are slidably connected inside the two rectangular frames 10, and the two rectangular frames 10 abut against the two hanging plates 9 respectively. After the hanging plate 9 is inserted into the rectangular frame 10, turning the second screw 11 in the direction of the hanging plate 9 will drive the clamping plate 12 to abut against the hanging plate 9, thereby further limiting the hanging plate 9 and the main body of the protective net 6 to increase the stability of the main body of the protective net 6 during use.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
