Technical Field

[0001] The utility model relates to the technical field of offshore photovoltaic, in particular to a wind-proof device for welding an offshore photovoltaic steel grid structure. Background Technique

[0002] When installing offshore photovoltaics, it is necessary to first install the offshore photovoltaic steel grid structure, and then install other components such as photovoltaic panels on the steel grid structure. The offshore photovoltaic steel grid structure is generally large in volume and weight, and most of the fittings are transported to the operation site in the form of loose parts, and then welding and other operations are carried out at the operation site to complete the assembly of the offshore photovoltaic steel grid. In actual assembly, a large amount of on-site welding is a major feature of the construction of the steel grid structure.

[0003] The on-site welding of the steel grid structure mainly includes butt welding and grid welding. Among them, butt welding is mainly used for welding structures such as truss steel pipes, and grid welding is mainly the assembly welding of hollow balls and rod bodies. In the welding process, all-round welding including various weld forms such as flat welding, horizontal welding, vertical welding and fillet welding is carried out. The operation difficulty and workload are relatively large during actual operation. Therefore, ensuring the welding quality of each welding is crucial for improving the engineering efficiency and reducing the working intensity of workers.

[0004] However, during actual operation, at the offshore photovoltaic installation site, there is a complex environment with strong wind speed and low temperature, which will seriously affect the welding quality, resulting in a reduction in the overall operation efficiency, affecting the construction period, and increasing the overall operation intensity. Therefore, how to avoid the complex environment at the offshore photovoltaic installation site from affecting the welding quality is a technical problem that needs to be solved urgently by those skilled in the art. Content of the Utility Model

By using a wind-proof cover, the part to be welded can be covered inside it to shield the wind and reduce the influence of strong wind on the welding quality. The wind-proof layer includes two fire-proof layers and a heat-insulating layer sandwiched between the two fire-proof layers, which can prevent the wind-proof layer from burning during welding and conduct heat preservation to avoid the influence of low temperature on the welding quality.

[0006] For the above technical problem, the technical solution provided by the utility model is a wind-proof device for welding an offshore photovoltaic steel grid structure, including a wind-proof cover. The inside of the wind-proof cover is an operation space for workers to weld. An entrance for workers to enter the operation space is also provided on the wind-proof cover. The wind-proof cover includes a wind-proof frame, and a wind-proof layer covering the operation space is arranged on the circumferential surface of the wind-proof frame.

The opposite sides of the left half layer and the right half layer are detachably connected, and the opposite sides of the left half layer and the right half layer are respectively fixedly connected to the left and right sides of the windproof frame.

[0010] Furthermore, a magnetic attraction structure is arranged between the opposite sides of the left half layer and the right half layer, and the left half layer and the right half layer are detachably connected through the magnetic attraction structure.

[0011] Furthermore, side support structures are arranged on the left and right sides of the windproof frame, and an upper support structure is arranged on the upper side of the windproof frame.

[0034] Referring to Figures 1 to 6 A windproof device for welding a steel grid structure of an offshore photovoltaic (hereinafter referred to as the windproof device) of the present utility model includes a windproof cover 1. The windproof cover 1 can cover the position to be welded and the staff inside it, providing an operation space for the staff to weld and a stable welding environment.

[0036] The specific structure of the windproof layer 3 is as shown in Figure 3As shown in the figure, it includes two layers of fireproof layers 7 and a heat insulation layer 8 sandwiched between the two fireproof layers 7. The fireproof layer 7 is a fireproof tarpaulin, and the heat insulation layer 8 is heat insulation cotton.

On the other hand, the heat insulation layer 8 can be used to keep the internal temperature stable and avoid the influence of low temperature on the welding quality, ensuring the orderly progress of welding operations in the complex environment of the offshore photovoltaic installation site.

[0037] Preferably, in this embodiment, as Figure 1 , 2 shown, the windproof frame 2 is integrally in the shape of a cuboid frame structure. The upper side frame of the cuboid frame structure is composed of a top horizontal rod 10.

Then, by pushing, the welding part to be welded is covered inside the windproof shield 1 through the opening structure on the front side. This is convenient for covering the welding part to be welded and for operation. At the same time, the opening structure on the front side is used to maintain air circulation.

Of course, in other embodiments, a zipper may also be provided between the left half layer 61 and the right half layer 62 to realize the detachable connection between the left half layer 61 and the right half layer 62.

[0043] Specifically, in this embodiment, as Figure 3 , 4 , shown in Figure 5, a sliding groove extending in the left-right direction is opened at the lower end of the sliding track 19, and the cross-section of the sliding groove is a T-shaped groove 191. The slider 20 is a T-shaped slider 20 adapted to the T-shaped groove 191. In this way, the slider 20 can be limited in the T-shaped groove 191 and can slide in the left-right direction. End fixing blocks 22 are also provided at the left and right ends of the T-shaped groove 191. The opposite ends of the upper ends of the left half layer 61 and the right half layer 62 are respectively fixed to the corresponding end fixing blocks 22, and the upper ends of the left half layer 61 and the right half layer 62 are respectively installed on the corresponding sliders 20. And, in this embodiment, the vertical dimension of the slider 20 is not greater than the vertical dimension of the T-shaped groove 191. In this way, the upper end of the inlet windproof layer 6 and the slider 20 can be received inside the T-shaped groove 191, improving the protection performance.

[0044] Of course, in other embodiments, the sliding track 19 may also be a horizontal sliding rod, and a plurality of sliding rings are sleeved on the sliding rod. The upper end of the inlet windproof layer 6 is fixed to the corresponding sliding ring, and the inlet windproof layer 6 is driven to slide through the sliding ring.

[0045] In this embodiment, preferably, side support structures are provided on the left and right sides of the windproof frame 2, and an upper support structure is provided on the upper side of the windproof frame 2. In this way, the structural strength of the windproof cover 1 can be improved.

[0046] Specifically, the side support structure includes a reinforcing cross beam 12 and two intersecting reinforcing diagonal beams 13. The upper support structure includes two reinforcing purlins 14 extending in the left-right direction and arranged at intervals in the front-back direction. The plurality of reinforcing purlins 14 are connected and fixed by a transverse connecting beam. In other embodiments, the number of the reinforcing purlins 14 can be set according to actual needs.

[0047] In this embodiment, as Figure 1 , 2 shown, two groups of side support structures are arranged at intervals in the left - right direction on each side. The side wind - proof layer 4 on each side is arranged between the two side support structures on the corresponding side, and the side wind - proof layer 4 is clamped by the two side support structures. Two groups of upper support structures are arranged at intervals in the vertical direction, and the upper wind - proof layer 5 is arranged between the two upper support structures, and the upper wind - proof layer 5 is clamped by the two upper support structures. In this way, by using the side support structure and the upper support structure, it is convenient to install and arrange the side wind - proof layer 4 and the upper wind - proof layer 5, and at the same time, it is convenient to maintain the shapes of the two, avoiding deformation caused by environmental influence and affecting the welding quality.

[0048] Of course, in other embodiments, when meeting the actual use requirements, only one side support structure and one upper support structure can be provided on each side.

[0049] Preferably, in this embodiment, an electric heating tube 18 is arranged at the inner top of the wind - proof cover 1. Specifically, as Figure 2 shown, at the left and right ends of the inner top surface of the wind - proof frame 2, an electric heating tube 18 extending in the front - rear direction is respectively fixed. By using the electric heating tube 18, the temperature inside the wind - proof cover 1 can be increased during welding, which can adapt to low - temperature environments and ensure the welding quality. At the same time, the two symmetrically arranged electric heating tubes 18 can, on the one hand, increase the heating speed, and on the other hand, ensure the uniformity of the temperature inside the wind - proof cover 1.

[0050] In this embodiment, preferably, a plurality of universal wheels 17 are arranged at the lower end of the wind - proof cover 1. Specifically, a universal wheel 17 is respectively arranged at the four corners of the bottom of the wind - proof frame 2, and the universal wheel 17 is a self - locking universal wheel 17 with a brake pedal. In this way, on the one hand, it is convenient to move the wind - proof cover 1, and on the other hand, it can prevent the wind - proof cover 1 from moving during welding.

[0051] The working process of this application: During the welding process, the wind - proof device is pushed to the welding point to be welded through the universal wheels 17, and it is ensured that the inlet wind - proof layer 6 faces the wind and the front - side opening structure faces away from the wind. Step on the brake pedal of the universal wheels 17 to lock the universal wheels 17, open the rear - side magnetic attraction structure 15, and the staff enters the inside of the wind - proof cover 1.

[0052] Close the magnetic attraction structure 15 to form a wind - proof space on the rear, upper, left, and right sides. At the same time, use the internal electric heating tube 18 to increase the environmental temperature in the operation space to ensure that the welding quality is controllable.

[0053] After the welding is completed, the magnetic attraction structure 15 is opened, and the operator picks up the brake pedal, then the windproof device can be pushed to the next welding point to be welded, repeating to form a welding environment. This device has the characteristics of being structurally compact, flexible and convenient, and can be moved at any time according to the welding position of the grid structure, achieving immediate use and arrival.

[0054] In summary, for the windproof device of the present utility model, by using the windproof cover 1, during welding, the part to be welded can be covered inside it to block the wind, and the staff enters its interior through the entrance 9 for welding, reducing the influence of strong wind on the welding quality.

At this time, during welding, the entrance windproof layer is opened, and the welding point is covered inside the windproof cover through the entrance. Then the staff enters the interior of the windproof cover to close the entrance windproof layer for operation. At this time, the windproof and heat preservation effects of the windproof cover can be improved. At the same time, due to the installation of universal wheels, there is a gap between the bottom of the windproof cover and the ground, forming a ventilation channel. For the convenience of operation, in this embodiment, a lighting lamp can be provided on the top inside the windproof cover.
