Description

Technical Field

[0001] The utility model relates to the technical field of cable construction, in particular to a photovoltaic DC special cable pay-off device. Background Art

[0002] Currently, photovoltaic DC cable installation typically involves using a horizontal reel (see "A Cable Payoff Reel" in publication number CN115557314A) or a vertical payoff rack (see "Payoff Rack" in publication number CN108975045A). However, both methods require relatively flat terrain for installation, which is time-consuming and inconvenient to transport due to the large number of accessories involved. Furthermore, personnel must be assigned to manage the cables near the reel during the payoff process to prevent them from getting stuck. Summary of the Invention

[0003] In view of this, the purpose of the present invention is to provide a photovoltaic DC special cable pay-off device that can achieve cable pay-off limit and ensure smooth cable pay-off.

[0005] Furthermore, the rotating part includes a first motor, which is arranged at the left end of the upper surface of the support base. A first gear is provided at the end of the output shaft of the first motor, and the first gear is provided in the support base. The lower surface of the winding drum is connected with a rotating shaft, and a second gear meshing with the first gear is provided on the rotating shaft.

[0006] Furthermore, the limiting member includes a connecting rod, the connecting rod is sleeved on the lower end of the support rod, a limiting slot is opened at the end of the connecting rod, a cover plate for covering the limiting slot is provided at the end of the connecting rod, a first guide wheel is provided on the left side and the front and rear surfaces of the limiting slot, a telescopic cylinder is embedded in the cover plate, a second guide wheel is provided at the end of the telescopic rod of the telescopic cylinder, and the second guide wheel is provided in the limiting slot, and a second motor for driving is provided in the first guide wheel and the second guide wheel.

[0007] The beneficial effects of the present invention are as follows: the present invention adds a winding drum, a limiting member and a rotating member to the device, and the cable reel can be directly placed on the ground or directly placed on a transport vehicle to be assembled with a guide frame, thereby improving the flexibility of use; during the line-paying process, the cable is passed through the limiting member for line-paying, and the rotating member is rotated to prevent the guide frame from getting stuck and the cable from being pulled out, thereby preventing the cable reel plate from getting stuck and the cable from being pulled out; the present invention has a simple structure and is easy to operate, can effectively save manpower and material resources, and improve work efficiency.

[0011] The present invention will be further described below with reference to the accompanying drawings.

[0012] See also Figures 1 to 3 As shown, the utility model provides an embodiment: a photovoltaic DC dedicated cable unwinder, comprising a support base 1, a winding drum 2 is provided on the upper surface of the support base 1, a rotating member 3 for driving the winding drum 2 to rotate is provided in the support base 1, a support rod 4 is connected to the upper surface of the winding drum 2 via a bearing, a limit member 5 for limiting the cable guide position is sleeved on the lower end of the support rod 4, a fixed block 6 is sleeved on the upper end of the support rod 4, and a limit ring 7 is connected to the right side of the fixed block 6. The cable can be guided by the limit member 5, and then pass through the limit ring 7, and the winding drum 2 is driven to rotate by the rotating member 3. The support rod 4 is connected to the winding drum 2 bearing, so the support rod 4 will not rotate due to the rotation of the winding drum 2. The rotation of the winding drum 2 can prevent the guide frame from being stuck and the cable from being pulled out, thereby preventing the cable from being stuck and the cable reel from being pulled out.

[0013] Please continue reading Figure 1 and Figure 3As shown, in one embodiment of the present invention, the rotating member 3 includes a first motor 31, which is disposed at the left end of the upper surface of the support base 1. A first gear 32 is disposed at the end of the output shaft of the first motor 31, and the first gear 32 is disposed within the support base 1. A rotating shaft 33 is connected to the lower surface of the winding drum 2, and a second gear 34 is disposed on the rotating shaft 33, which meshes with the first gear 32. The first motor 31 can drive the first gear 32 to rotate, and the rotation of the first gear 32 can drive the second gear 34 to rotate, thereby enabling the winding drum 2 to rotate, facilitating the pay-off operation of the optical cable.

[0014] Please continue reading Figure 1 and Figure 2 As shown, in one embodiment of the present invention, the limiting member 5 includes a connecting rod 51, which is sleeved on the lower end of the support rod 4. A limiting slot 52 is defined at the end of the connecting rod 51. A cover plate 53 is provided at the end of the connecting rod 51 for covering the limiting slot 52. A first guide wheel 54 is provided on the left side and front and rear surfaces of the limiting slot 52. A telescopic cylinder 55 is embedded in the cover plate 53. A second guide wheel 56 is provided at the end of the telescopic rod of the telescopic cylinder 55. The second guide wheel 56 is disposed in the limiting slot 52. A second motor (not shown) is provided in each of the first and second guide wheels 54, 56. The telescopic cylinder 55 drives the second guide wheel 56 to move, and the second guide wheel 56 and the first guide wheel 54 come into contact with the cable. Then, the second motor drives the second guide wheel 56 and the first guide wheel 54 to rotate, thereby achieving the cable payout and guiding function.

[0015] The telescopic cylinder and the motor in the present invention are both prior art, and those skilled in the art are already well aware of them, so they will not be described in detail here.
