The adjustment component 7 includes a fixing ring 71, the inner wall of the fixing ring 71 is fixedly connected to the outer wall of the fixed rod 2, and the two sides of the fixing ring 71 are respectively fixedly connected It is connected to a support seat 72, and a winding wheel 73 is provided on the opposite side of the two support seats 72. The two axial ends of the winding wheel 73 respectively pass through the surface of the two support seats 72. The outer surface of the winding wheel 73 is fixed and wrapped with a connecting rope 8. The top of the connecting rope 8 is fixedly connected to one end of the cross bar 4. The fixing rod 2 and the cross bar 4 are respectively assembled by multiple I-shaped rods in a threaded connection manner, so that the fixing rod 2 and the cross bar 4 can be disassembled after use, which is convenient for carrying and transportation. A battery module is installed on the base 1, and the battery module is used to power the driver 11.

[0027] Specifically, the fixed rod 2 and the rotating frame are used to support the connecting cross bar 4. When the cross bar 4 rotates, the traction wheel 6 can be driven upward through the traction frame 5 to move, thereby adjusting the height of the traction wheel 6. The support seat 72 is used to rotate and support the winding wheel 73. When in use, the device is moved to the corresponding photovoltaic installation area, one end of the cable is passed through the traction wheel 6, and then the winding wheel 73 is rotated to retract the connecting rope 8. When the connecting rope 8 is wound, the cross bar 4 is pulled to rotate, so that the longer end of the cross bar 4 rotates upward, thereby lifting the cable through the traction wheel 6, which is convenient for the staff to pull the cable for use when laying it, so that the required cable length can be flexibly cut, providing convenient conditions for personnel to lay DC cables, avoiding wear between the cable and the ground, and speeding up the laying of DC cables.

[0028] A slot 74 is provided on one side of the shaft end of the winding wheel 73, and a rotating disk 75 is slidably connected to the surface of the slot 74.

When the position of the cross bar 4 needs to be fixed, stop pulling the handle 79 outward, so that the positioning column 76 is tightly inserted into the corresponding positioning hole 78 through the elastic force of the spring 77, thereby locking the rotation angle of the cross bar 4, without the need for manual support, saving human resources.

[0030] Example 2

[0031] For comparison with Example 1, please refer to Figure 5 As shown, the present invention provides another embodiment, in which two fixed wheels 10 are fixedly connected to one side of the base 1 .

[0032] Two groups of support components 9 are provided on the upper surface of the base 1. The support component 9 includes a connecting column 91. The bottom end of the connecting column 91 is fixedly connected to the upper surface of the base 1. The top of the connecting column 91 is fixedly connected to a fixed card plate 92. The lower side wall of the connecting column 91 is slidably connected to a movable card plate 93. A card groove 94 is respectively provided on the opposite side of the fixed card plate 92 and the movable card plate 93. The card groove 94 is set to be V-shaped or arc-shaped. The lower surface of the fixed card plate 92 is fixedly connected to a guide rod 95. The bottom end of the guide rod 95 is fixedly connected to a fixed protrusion 96. The outer wall of the fixed protrusion 96 is fixedly connected to the outer wall of the connecting column 91 Then, the lower surface of the fixed card plate 92 is rotatably connected to a screw 97, and a driver 11 is provided below the screw 97. The bottom end of the driver 11 is fixedly connected to the upper surface of the base 1, and the driving end of the driver 11 is fixedly connected to the bottom end of the screw 97. The guide rod 95 and the screw 97 respectively pass through the movable card plate 93, and the surface of the screw 97 is threadedly connected to the upper connecting seat 98 and the lower connecting seat 99. The guide rod 95 passes through the surfaces of the upper connecting seat 98 and the lower connecting seat 99, and the lower surface of the lower connecting seat 99 is fixedly connected to the movable wheel 16. The surface of the base 1 is provided with an opening 12 corresponding to the movable wheel 16.

[0033] Specifically, the driver 11 is used to drive the screw 97 to rotate, and the screw 97 rotates to adjust the height of the upper connecting seat 98 and the lower connecting seat 99. When the upper connecting seat 98 and the lower connecting seat 99 are located at the bottom, the movable wheel 16 passes through the opening 12 and rests against the ground, thereby cooperating with the fixed wheel 10 to facilitate the movement of the device. When the upper connecting seat 98 and the lower connecting seat 99 rise a certain distance until the movable wheel 16 is higher than the base 1, one end of the ground rests against the ground to tilt, thereby pushing the cable reel onto the base 1 or removing the cable reel, and placing the axial end of the cable reel above the slot 94 of the movable clamping plate 93. The upper connecting seat 98 rises again to push the cable reel upward until it rests against the fixed clamping plate 92, thereby supporting the cable reel in mid-air, so that the cable can be led out of the reel more smoothly, while preventing the cable reel from falling off.

[0034] A plurality of thread grooves 13 are formed on the surface of the connecting column 91 from top to bottom, and a threaded through hole 14 is formed on the surface of the movable clamping plate 93 . A positioning bolt 15 is threadedly connected to the threaded through hole 14 .

[0035] Specifically, when the device needs to be moved when the movable clamping plate 93 carries the cable reel, the positioning bolt 15 is removed and connected to the threaded groove 13 below the movable clamping plate 93, thereby providing temporary support for the movable clamping plate 93, so that when the lower connecting seat 99 is lowered and the movable wheel moves against the ground, it will not affect the support of the device for the cable reel.

[0036] Through the use of wires by those skilled in the art, all electrical components in this case are connected to their corresponding power supplies, and appropriate controllers should be selected for electrical connection with the driver 11 according to actual conditions to meet control requirements. For specific connections and control sequences, reference should be made to the following working principle, in which the electrical components are electrically connected in a sequential working order. The detailed connection methods are well-known technologies in this field. The following mainly introduces the working principles and processes, and does not explain the electrical control.

[0037] The parts not involved in the device are the same as those in the prior art or can be implemented by using the prior art.

[0038] Working principle: When in use, move the device to the corresponding photovoltaic installation area, pass one end of the cable through the traction wheel 6, and then rotate the reel 73 to retract the connecting rope 8. When the connecting rope 8 is reeled in, pull the cross bar 4 to rotate, so that the longer end of the cross bar 4 rotates upward, thereby lifting the cable through the traction wheel 6, making it convenient for the staff to pull the cable for use during laying, so that the required cable length can be flexibly cut, providing convenient conditions for personnel to lay DC cables, avoiding wear and tear between the cable and the ground, and speeding up the laying of DC cables.

[0039] When rotating the winding wheel 73, the staff holds the handle 79 and pulls the rotating disk 75 outward, so that the positioning column 76 exits the positioning hole 78, and then rotates the handle 79 to drive the rotating disk 75 to rotate, and the rotating disk 75 drives the winding wheel 73 to rotate, thereby realizing the retraction and release of the connecting rope 8 and adjusting the rotation angle of the cross bar 4. When the position of the cross bar 4 needs to be fixed, stop pulling the handle 79 outward, so that the positioning column 76 is tightly inserted into the corresponding positioning hole 78 through the elastic force of the spring 77, thereby locking the rotation angle of the cross bar 4, without the need for manual support, saving human resources.

[0040] The driver 11 is used to drive the screw 97 to rotate, and the screw 97 rotates to adjust the height of the upper connecting seat 98 and the lower connecting seat 99. When the upper connecting seat 98 and the lower connecting seat 99 are located at the bottom, the movable wheel 16 passes through the opening 12 and rests against the ground, thereby cooperating with the fixed wheel 10 to facilitate the movement of the device. When the upper connecting seat 98 and the lower connecting seat 99 rise a certain distance until the movable wheel 16 is higher than the base 1, one end of the ground rests against the ground to tilt, thereby pushing the cable reel onto the base 1 or removing the cable reel, and placing the axial end of the cable reel above the slot 94 of the movable clamping plate 93. The upper connecting seat 98 rises again to push the cable reel upward until it rests against the fixed clamping plate 92, thereby supporting the cable reel in the air, so that the cable can be led out of the reel more smoothly, while preventing the cable reel from falling off.
