Description
Technical Field
[0001] The utility model relates to the technical field of wind-proof equipment for aerial welding operations, and particularly relates to a portable aerial welding wind-proof device for an open-air dock environment. Background Technique
[0002] With the transformation of the global energy structure and the enhancement of environmental protection awareness, and with the promotion of the dual-carbon concept, as an important part of clean energy, offshore photovoltaic projects have developed rapidly in recent years. Different from onshore photovoltaics, offshore photovoltaic brackets have large design sizes and numerous welding points. Coupled with the harshness of the offshore environment, the requirements for welding quality are extremely strict. However, existing welding technologies are mostly applicable to land environments and are insufficiently adaptable to such special offshore environments. Especially for welding operations carried out in an open-air dock environment, where there are strong winds all year round along the coast and the construction environment is poor, welding operations are often severely affected by natural conditions such as strong winds.
[0003] Existing welding wind-proof technologies mainly rely on floor-standing welding wind-proof devices. Although these devices are diverse in type and mature in technology, they are usually heavy, with complex installation and disassembly processes, and occupy a large area. In an environment like a dock where space is limited and strong winds are often faced, the application of these devices is greatly restricted. In addition, aerial welding operations are relatively common in the steel structure field, but the required wind-proof devices often need to build a special platform for fixation, which not only increases the construction difficulty and risk but also is not conducive to quickly meeting the requirements of offshore photovoltaic projects for efficiency and flexibility.
[0004] In the context of existing technologies, welding operations on offshore photovoltaic platforms face a series of challenges. First, existing wind-proof devices often cannot effectively cope with strong winds in the dock environment, resulting in difficult-to-guarantee welding quality. Second, the inconvenience of installation and disassembly in existing technologies seriously affects construction efficiency and increases project costs. Third, existing wind-proof devices have poor adaptability to complex structures and are difficult to meet the diverse requirements for wind-proof measures during the installation of the truss structure of the photovoltaic platform. The existence of these problems not only restricts the construction speed and quality of offshore photovoltaic projects but also poses a potential threat to construction safety.
[0005] In view of this, the demand for efficient, lightweight, and flexible wind-proof devices in welding operations on offshore photovoltaic platforms is becoming increasingly urgent. This demand has promoted in-depth analysis and improvement of existing technologies, with the expectation of developing a new type of welding wind-proof device that can adapt to the open-air dock environment and meet the requirements of rapid construction. This solution has emerged precisely in such a background, aiming to solve the deficiencies of existing technologies in welding operations on offshore photovoltaic platforms, provide a small, lightweight, and easy-to-install-and-dismantle aerial welding wind-proof device to adapt to the special requirements of the open-air dock environment, improve construction efficiency, ensure welding quality, and at the same time reduce construction risks. Summary of the Invention
[0006] In order to achieve the above-mentioned utility model purpose and address the above technical problems, the present utility model provides a portable aerial welding windproof device for the open-air environment of a wharf.
[0007] Its technical solution is as follows: It includes a frame body composed of vertically arranged vertical frame columns and horizontally arranged horizontal frames. The horizontal frame includes an upper connecting crossbar and a lower connecting crossbar. A neodymium iron boron magnet block is slidably connected to the lower connecting crossbar, and a three-proof cloth is arranged on the outer wall of the frame body;
[0008] The lower half of the three-proof cloth is set in a forked form.
[0009] Both the upper connecting crossbar and the lower connecting crossbar are connected to the vertical frame columns through mountain-shaped buckles;

[0011] A horizontal chute is opened in the middle of the lower connecting crossbar. The chute penetrates the side wall of the lower connecting crossbar, and the neodymium iron boron magnet block is slidably connected to the chute. The neodymium iron boron magnet block is a strong magnet and can move left and right on the lower connecting crossbar. It can be flexibly adjusted according to the position of the on-site truss structure, so that the windproof shed can be stably adsorbed on the truss members.
[0012] The mountain-shaped buckles are arranged at the connection points of the vertical frame columns with the upper connecting crossbar and the lower connecting crossbar. Through the buckle connection, this windproof device can be freely disassembled;

When connecting, one of the two connected parts fixes a positive mountain-shaped buckle, and the other fixes a reverse mountain-shaped buckle. The card slots of the two mountain-shaped buckles are clamped together.
[0015] The three-proof cloth is made of PVC fiberglass cloth, which is light in weight. A number of magnetic fasteners are arranged on the three-proof cloth. The upper part of the three-proof cloth is fixed to the upper connecting crossbar by winding with magnetic fasteners, and the magnetic fasteners on the left, right and adjacent sides of the three-proof cloth are fitted together.
[0016] The lower half of the three-proof cloth is provided with a three-proof cloth bifurcation, and a magnetic fastener is arranged inside. After the crisscrossing rods pass through the three-proof cloth bifurcation, the bifurcation is closed by the magnetic fastener inside. The magnetic fastener is arranged on the three-proof cloth, and the three-proof cloth is attached to the four surfaces by the magnetic fastener to ensure that there is no wind in the shed.
[0017] The center of the lower connecting crossbar is hollowed out, and the lower connecting crossbar is held by a neodymium iron boron magnet block. The neodymium iron boron magnet block can move freely on the lower connecting crossbar to adapt to the changing component sizes on site.
[0018] The beneficial effects of the technical solution provided by the embodiment of the utility model are as follows: the utility model provides a compact, lightweight, detachable and fixed windproof device in the air, which aims to solve the problem of windproof during the welding of the criss-crossing rods of the photovoltaic platform truss structure during installation.
