A plurality of movable grooves 31 are provided and distributed along the length direction. A screw 32 is movably connected inside the movable groove 31. A screw sleeve 33 is threadedly connected to the bottom surface of the screw 32. The bottom of the screw sleeve 33 is fixedly connected to both sides of the top and bottom of the photovoltaic panel body 1. A pressing ring 34 is threadedly connected to the top surface of the screw 32.

[0024] As a technical optimization scheme of the utility model, by providing the reinforcing mechanism 3, when the fixing frames 2 are clamped on both sides of the photovoltaic panel body 1, the movable grooves 31 on the fixing frames 2 will be inserted into the screws 32. Then, the user can rotate the pressing ring 34, so that the pressing ring 34 rotates and moves inward. Then, the pressing ring 34 will clamp and reinforce the fixing frames 2, improving the use effect of the fixing frames 2.

[0025] Referring Figure 2 to the figure, the limiting mechanism 4 includes a first limiting seat 41. The outer side of the first limiting seat 41 is fixedly connected to the outer side of the inner wall of the fixing frame 2. Second limiting seats 42 are fixedly connected to both sides of the photovoltaic panel body 1. Limiting grooves 43 are opened on the outer sides of the second limiting seats 42 and the inner sides of the first limiting seats 41. A plurality of limiting grooves 43 are provided and distributed along the length direction.

[0026] As a technical optimization scheme of the utility model, by providing the limiting mechanism 4, when the user positions and bundles the DC connecting wires, the DC connecting wires can be inserted into the limiting grooves 43 opened on the first limiting seat 41 and the second limiting seat 42, so as to arrange and distribute the DC connecting wires, and at the same time, the situation that the DC connecting wires are damaged by clamping can be avoided.

[0027] Referring Figure 2 to the figure, heat dissipation holes 5 are opened on the inner side of the first limiting seat 41. A plurality of heat dissipation holes 5 are provided and distributed along the length direction. The heat dissipation holes 5 are opened to the outer side of the fixing frame 2.

[0028] As a technical optimization solution of the present utility model, by providing heat dissipation holes 5, when the DC connecting wire that is being constricted is limited by the first limiting seat 41 and the second limiting seat 42, the heat generated during the use of the DC connecting wire can be discharged outward through the heat dissipation holes 5, preventing heat from accumulating in the first limiting seat 41 and the second limiting seat 42 and thus avoiding the situation of overheating of the DC connecting wire.

[0029] Reference Figure 2 , an L-shaped rod 6 is fixedly connected to the surface of the pressing ring 34, and a plurality of L-shaped rods 6 are provided and distributed in a ring shape.

[0030] As a technical optimization solution of the present utility model, by providing the L-shaped rod 6, when the user needs to rotate the pressing ring 34, the user can rotate it by holding the L-shaped rod 6, and then the L-shaped rod 6 will drive the pressing ring 34 to rotate, thereby giving the user a force application point that is convenient for applying force and improving the use effect.

[0032] As a technical optimization solution of the present utility model, by providing the connecting rod 7 and the limiting disc 8, and using the fact that the diameter of the limiting disc 8 is larger than the inner diameter of the pressing ring 34, after the pressing ring 34 rotates and disengages from the screw rod 32, the limiting disc 8 can prevent the pressing ring 34 from moving upward and disengaging from the screw rod 32, thus avoiding the situation of loss of the pressing ring 34.

[0033] Reference Figure 3 , a filling ring 9 is arranged inside the pressing ring 34, and the filling ring 9 is fixedly connected to the pressing ring 34 through PET glue.

[0034] As a technical optimization solution of the present utility model, by providing the filling ring 9, when the user clamps the fixed frame 2 with the pressing ring 34, the inner side of the pressing ring 34 contacts the fixed frame 2 through the filling ring 9, thereby greatly reducing the gap between the pressing ring 34 and the fixed frame 2, improving the fixing strength, and then using the advantage of strong adhesiveness of PET glue, thereby improving the fixing strength of the filling ring 9.

[0035] Working principle and usage process of the present utility model: After the user connects all the DC connection wires of the photovoltaic panel body 1 to the inverter control integrated machine, the user can directly attach the DC connection wires on the photovoltaic panel body 1 to both sides of the photovoltaic panel body 1. Subsequently, cover the fixing frame 2 over the DC connection wires and buckle it on both sides of the photovoltaic panel body 1. At this time, the straight connection wires will quickly be clamped on both sides of the photovoltaic panel body 1. When expanding and contracting the two connected photovoltaic panel bodies 1, no work needs to be done, and the fixing frame 2 will adjust along with the photovoltaic panel body 1. When clamping the fixing frame 2 on both sides of the photovoltaic panel body 1, the movable slot 31 on the fixing frame 2 will be inserted into the screw rod 32. Subsequently, the user can rotate the pressing ring 34, causing the pressing ring 34 to rotate and move inward. Then, the pressing ring 34 will clamp and reinforce the fixing frame 2, improving the usage effect of the fixing frame 2. When the user positions and bundles the DC connection wires, the DC connection wires can be inserted into the limiting slots 43 opened on the first limiting seat 41 and the second limiting seat 42, so as to arrange and distribute the DC connection wires, and at the same time, avoid the situation that the DC connection wires are damaged by clamping, improving the usage effect. In some embodiments, taking advantage of the low cost of PP plastic, the usage cost of the fixing frame 2 is reduced, and the ability to facilitate wire bundling is achieved.

[0036] In summary: For the photovoltaic wire fixing structure of this photovoltaic mobile power station, by setting the fixing frame 2 and directly covering the fixing frame 2 over the DC connection wires and buckling it on both sides of the photovoltaic panel body 1, at this time, the straight connection wires will quickly be clamped on both sides of the photovoltaic panel body 1, solving the problem that since the mobile power station adopts a centralized photovoltaic energy storage inverter integrated machine, after all the solar panel strings are connected, all their DC connection wires are connected to the inverter control integrated machine, the circuit is long, fixed and laid along the guide rail, and all the connection wires need to be removed every time when expanding and folding, the work is cumbersome and time-consuming and prone to errors, increasing the labor cost and installation time.
