Description

Technical Field

[0001] This application belongs to the technical field of photovoltaic construction protection, and specifically relates to a safety protection device for photovoltaic construction. Background Art

[0002] The safety protection devices for photovoltaic construction are a series of equipment and measures designed to ensure the safety of personnel during the construction of photovoltaic power stations. These safety protection devices include not only personal protective equipment for specific operations, but also general protection equipment such as preventing material falling, high-altitude operation safety, and electrical safety, as well as professional protection devices for specific construction links such as photovoltaic panel installation, bracket erection, and cable wiring.

[0003] For example, the utility model patent with the publication number CN218205746U discloses a safety protection device for the construction of a roof photovoltaic power station, including a base. The base is in a U shape, and a groove is formed on the surface of the base. The inner wall of the groove is rotatably connected with a protective baffle, and the surface of the base is rotatably connected with a lead screw. A movable box is threadedly connected to the surface of the lead screw. A buffer mechanism is arranged inside the movable box. A buffer pull rod is rotatably arranged on the surface of the buffer mechanism. One end of the buffer pull rod away from the buffer mechanism is hinged to the surface of the protective baffle. The buffer mechanism includes a guide slide rod fixedly installed on the inner wall of the movable box. For this safety protection device for the construction of a roof photovoltaic power station, by installing the base on the surface of the roof structure and using an adjusting wheel, the unfolding angle of the protective baffle can be adjusted and fixed, so as to be suitable for installing the protection device on roofs with different inclined slopes. The installation is convenient and fast. The protective baffle can be used to block and protect the equipment and construction personnel used during the roof construction process.

[0004] However, it is found in the actual use process that: when installing photovoltaic panels on a sloping roof, ensuring the safety of construction personnel is crucial. This device uses the erected objects of the protective baffle for physical isolation to prevent construction personnel from falling from a height;

[0005] However, the size of the protective baffle of this device is fixed, making it difficult to adapt to different sizes of sloping roofs, and the base and the protective baffle are not convenient enough in terms of storage and transportation. Therefore, a safety protection device for photovoltaic construction is provided. Utility Model Content

[0023] Reference Figure 1 、 Figure 2 And Figure 3 , Inside the U-shaped storage plate 4, there is a scissor-type adjusting rod 2 hinged. On the side of the U-shaped storage plate 4 away from the connecting convex block 3, there is a U-shaped storage plate 3. One end of the scissor-type adjusting rod 2 away from the U-shaped storage plate 4 is hinged to the inside of the U-shaped storage plate 3; through the U-shaped storage plate 4 and U-shaped storage plate 3 provided, it is convenient for the opening and storage of the scissor-type adjusting rod 2. The scissor-type adjusting rod 2 has the same structure as the scissor-type adjusting rod 1, so it is convenient for the U-shaped storage plate 4, the scissor-type adjusting rod 2 and the U-shaped storage plate 3 to form a vertical protection fence, which is convenient for further safety protection of the personnel at the photovoltaic construction site.

[0024] Reference Figure 1 、 Figure 2 , On one side of the left U-shaped storage plate 1, there are two rectangular blocks 7 fixed. On one side of the right U-shaped storage plate 1, there are two fixing plates 8 corresponding to the rectangular blocks 7. At the front end of the fixing plate 8, there is an insertion plate 9, and the insertion plate 9 is inserted into the inside of the rectangular block 7; the side of the rectangular block 7 close to the fixing plate 8 is open, so it is convenient for the insertion plate 9 to be inserted into it, so that the two U-shaped storage plates 1 are positioned and connected together.

[0025] Reference Figure 1 、Figure 2 The top surface of the rectangular block 7 is penetrated by a bolt 10, and a threaded hole 11 is formed on the top surface of the insertion plate 9. The bolt 10 is threadedly connected to the inside of the threaded hole 11. By providing the bolt 10, it is convenient to fix the insertion plate 9 and convenient to fix the two U-shaped storage plates 1 connected together for positioning.

By providing the U-shaped handle 12, it is convenient to drive the two U-shaped storage plates 1 to unfold or be stored, improving convenience. By providing that the outer sheath 16 is made of sponge material, it is convenient to improve the comfort of the personnel's hands.

[0027] Reference Figure 1 、 Figure 2 Reflective stickers 15 are fixedly installed on the sides of the two U-shaped storage plates 1 away from each other.

[0028] The implementation principle of an embodiment of the safety protection device for photovoltaic construction in this application is as follows: When the device is in a normal state, it is in a compact storage form as shown (in the attached Figure 2 description), which is convenient for storage and movement and is suitable for the safety protection of photovoltaic installation construction sites. When in use, the operation process is as follows:

[0029] First, by unscrewing the bolt 10, the operator can easily separate and unfold the two U-shaped storage plates 1. The two U-shaped storage plates 1 are combined with the scissor-type adjusting rod 1, so that when the two U-shaped storage plates 1 drive the scissor-type adjusting rod 1 to unfold, a horizontal protective fence is formed.

[0030] To ensure the stability of the U-shaped storage plate 1 on the sloping roof or the support of the photovoltaic construction site, the operator will use a fixing bolt to penetrate the circular hole 14 and firmly lock it in the designated position to ensure stability in various usage scenarios.

[0031] Immediately afterwards, the operator pulls the U-shaped storage plate 3 6 to cause the scissor-type adjusting rod 2 5 to unfold.
