[0037] The utility model discloses in conjunction with the embodiment in great detail, but the utility model is not limited to these embodiments.

[0038] The utility model discloses an embodiment provides a kind of photovoltaic net rack jacking up and transporting device, as shown in Figs. 1 to 4 The device includes:

[0039] Support 1;

[0040] Supporting plate 4 is connected at the top of support 1, and the top has inclined supporting surface, for supporting the base 81 of photovoltaic net rack 8, so that photovoltaic net rack 8 has preset inclination;

[0041] Limiting component is set on supporting plate 4, for limiting the relative position of the base 81 of photovoltaic net rack 8 and supporting plate 4;

[0042] Lifting assembly is connected with the bottom of support 1, for driving support 1 to lift.

[0043] Specifically, the photovoltaic grid 8 can be a bolt ball grid. The bolt ball grid can include a base 81, a plurality of bolt ball nodes 82 and a plurality of rod members 83. When assembling the bolt ball grid, usually a bolt ball node 82 is first fixed on the base 81, and then the other bolt ball nodes 82 are connected with the bolt ball node 82 fixed on the base 81 through corresponding rod members 83, respectively, so as to complete the assembly of the bolt ball grid. Among them, the bolt ball node 82 connected with the base 81 and the base 81 are welded together.

[0044] In the offshore photovoltaic project, the photovoltaic grid 8 is generally installed at the top of the pile foundation arranged on the sea, and its installation position is relatively high from the sea level. Therefore, after the photovoltaic grid 8 is assembled, the photovoltaic grid 8 needs to be transported as a whole to the designated position on the sea, and then lifted to the installation position at the preset height by the lifting device to complete the installation. When installing the photovoltaic grid 8, in order to maximize the use of solar energy, it is usually necessary to adjust the photovoltaic grid 8 to be inclined according to the incident angle of sunlight, so that the photovoltaic modules laid thereon have a preset inclination, thereby improving the power generation efficiency of the photovoltaic modules.

[0045] The existing transportation device and lifting device can only place the photovoltaic grid 8 horizontally in order to ensure the safety and stability during transportation and lifting, which makes the photovoltaic grid 8 be transported to the installation position in a horizontal attitude and the inclination angle of the photovoltaic grid 8 can only be adjusted in the air at a high position from the sea level. Since the area and span of the photovoltaic grid 8 are relatively large, it is difficult to adjust the inclination angle of the photovoltaic grid 8 in the air, which causes the installation process of the photovoltaic grid 8 to be complicated and the installation efficiency to be low. Therefore, in order to simplify the installation process of the photovoltaic grid 8, it is necessary to avoid adjusting the inclination angle of the photovoltaic grid 8 in the air, which requires the inclination angle of the photovoltaic grid 8 to be adjusted according to the preset inclination of the photovoltaic modules before lifting. However, the existing transportation device and lifting device do not have a limiting structure capable of maintaining the inclined setting of the photovoltaic grid 8, so the photovoltaic grid 8 cannot be set to be inclined before lifting.

[0046] The utility model can solve the above-mentioned problem, the utility model sets up the supporting plate 4 on the support 1, and the supporting surface of the supporting plate 4 is set to be inclined according to the preset inclination of the photovoltaic module, so that the photovoltaic grid 8 placed on the supporting surface naturally has the required inclination angle. In this way, the photovoltaic grid 8 can be adjusted to be inclined before lifting, without the need to adjust the inclination angle of the photovoltaic grid 8 in the air, thereby effectively simplifying the installation process of the photovoltaic grid 8, reducing the installation difficulty, improving the installation efficiency, and facilitating the implementation of the streamlined installation operation of the large-span photovoltaic grid 8.

[0051] In this embodiment, the bottom surface of the base 81 of the bolt ball net rack is circular, and the supporting surface on the top of the supporting plate 4 is also circular, the area of the supporting surface being greater than the area of the bottom surface of the base 81. The stop block 3 is arc-shaped and is fixed to the edge of the supporting surface, and at least one bolt hole is formed in the stop block 3. Each limiting bolt is threadedly connected in the corresponding bolt hole. When the base 81 of the bolt ball net rack is placed on the inclined supporting plate 4, the base 81 of the bolt ball net rack can be limited in multiple directions by tightening the plurality of limiting bolts to abut against the base 81 of the bolt ball net rack, so as to prevent the base 81 of the bolt ball net rack from sliding down along the inclined supporting surface. Meanwhile, the stop block 3 can also effectively prevent the base 81 of the bolt ball net rack from sliding down before the limiting bolts are tightened.

[0052] In practice, stop blocks 3 of different heights can be arranged to limit the base 81 from different heights, so as to enhance the fixation of the base 81.

[0053] Specifically, the connection between the support 1 and the supporting plate 4, and the connection between the supporting plate 4 and the stop block 3 can all adopt welding, and the welding seam can be a single-bevel two-stage welding seam. In this case, the welding position of the supporting plate 4 and the stop block 3 can be located on the outer side of the supporting plate 4, and the inner side of the supporting plate 4 should not be welded when the welding on the outer side of the supporting plate 4 can ensure the connection strength of the supporting plate 4 and the stop block 3.
