The utility model provides a driving power supply box, which comprises a power supply box shell and plugs, two ends of the power supply box shell are provided with openings, and the plugs are installed at the openings to plug the openings; the two sides of the inner wall of the power box shell extend inwards in the length direction of the power box shell to form clamping grooves, the inner side of the plug extends towards the opening to form a fixed convex edge, the fixed convex edge extends into the opening and then is connected with the clamping grooves in a clamped mode, and glue is coated between the fixed convex edge and the interior of the power box shell for fixing. By adopting the scheme, the defects that the plug is fixed by a screw, a special tool is needed for installation, and the screw is easy to rust when exposed in the air are overcome, so that the assembly convenience of the power supply driving box and the installation comprehensiveness of the power supply driving box are improved; moreover, as the clamping grooves are formed in the inner wall of the power supply box shell, after the fixed convex edges are clamped with the clamping grooves, the situation that the plugs fall off due to deformation of the power supply box shell is avoided.

The present invention discloses a splicing mechanism and a photovoltaic curtain wall for fixing photovoltaic modules, which relate to the technical field of photovoltaic modules, including a plurality of photovoltaic panels, and also including a gap control splicing mechanism for connecting the photovoltaic panels, and an automatic adjustment mechanism for controlling the movement of the gap control splicing mechanism according to the temperature change between the photovoltaic panels. In the initial installation state, there is no restriction on the gap between the photovoltaic panels. Therefore, when installing adjacent photovoltaic panels, the probability of edge touching during the splicing process is greatly reduced due to the large installation gap left. When the installation is completed, the gap between the photovoltaic panels will be automatically adjusted. The gap of the photovoltaic panels can be automatically adjusted through the assembly. First, it can avoid the photovoltaic panels from being affected by the temperature and causing thermal expansion, which causes the edges to conflict with each other. Secondly, when the gap is increased, it can promote gas circulation, thereby improving the heat dissipation of the photovoltaic panels.

This invention relates to the field of wind turbine installation, specifically disclosing a wind turbine installation stability detection and compensation device, comprising: several positioning frames; a positioning base assembly connected to the positioning frames; a central stabilizing seat assembly connected to the side of the positioning base assembly away from the positioning frames; a wind turbine assembly connected to the central stabilizing seat assembly; a stability compensation device connected to the positioning base assembly and penetratingly connected to the central stabilizing seat assembly; and a stabilizing frame assembly connected to the central stabilizing seat assembly. The stability compensation device includes: a sensing device connected internally to the central stabilizing assembly; and a feedback compensation component connected to the positioning base assembly and penetratingly connected to the central stabilizing seat assembly. This device can detect the tilting trend of the wind turbine and compensate for its tilt, preventing it from tipping over, in conjunction with the stabilizing frame assembly.
