It should be understood that the specific examples described herein are only used to explain the utility model, and are not used to limit the utility model.

[0018] In order to explain the technical scheme of the utility model, the following will be explained by specific examples.

[0019] For the convenience of illustration, only parts related to the embodiments of the utility model are shown.

[0020] In combination Figures 1-4 As shown in the figure, the photovoltaic cable pay-off machine comprises a rack 1, the front end of the rack 1 is respectively provided with a vertical plate 2 and a right clamping arm 3, the rear end is provided with a sliding mechanism, the vertical plate 2 and the right clamping arm 3 are upwardly provided with a guide frame 41, the guide frame 41 is provided with a wire guide assembly, a pair of sliding rods 4 are arranged between the vertical plate 2 and the right clamping arm 3, a left clamping arm 6 is arranged on the sliding rod 4 through a sliding sleeve 5, the terminal ends of the left and right clamping arms are respectively provided with clamping shafts 7, the right clamping arm 3 is provided with a driving assembly for driving the clamping shaft 7 on the same side to rotate, the vertical plate 2 is provided with a clamping mechanism for driving the left clamping arm 6 to move left and right, the clamping mechanism comprises a lead screw 8 rotatably installed between the vertical plate 2 and the right clamping arm 3, the left clamping arm 6 is internally provided with a lead sleeve 9, and the lead screw 8 is located in the lead sleeve 9, and the vertical plate 2 is provided with a clamping motor 10 for driving the lead screw 8 to rotate.

[0021] In the field of photovoltaic energy, as an important component for connecting photovoltaic modules, inverters, distribution boxes and other key equipment, the laying efficiency and quality of photovoltaic cables are directly related to the power generation efficiency and operation stability of photovoltaic power stations. With the expansion of the construction scale of photovoltaic power stations and the improvement of the intelligent level, the laying requirements for photovoltaic cables are also getting higher and higher.

[0022] As is known to all, the photovoltaic cable coil is usually wound on a pay-off reel for storage, transportation and pay-off during the installation process of the photovoltaic system, and a through hole is formed in the axial position of the pay-off reel. The pay-off reel can be installed on the device during the laying of the photovoltaic cable, and the pay-off of the photovoltaic cable is realized through the device.

[0023] As Figure 2 , the front end of the rack is rotatably provided with a rotating shaft 26, the rotating shaft 26 is provided with the vertical plate 2 and the right clamping arm 3, and a pair of sliding rods 4 are arranged between the vertical plate 2 and the right clamping arm 3. The two sliding rods 4 are provided with sliding sleeves 5, and the left clamping arm 6 is arranged on the two sliding sleeves 5, and the left and right clamping arms are rotatably provided with clamping shafts 7, so that when the left clamping arm is lifted, the right clamping arm is also lifted, and the two clamping shafts rotate synchronously during the lifting process of the left and right clamping arms, which can adapt to and clamp pay-off reels of different sizes.

[0024] When the pay-off reel 25 is installed on the device, first push the pay-off reel to the sliding mechanism, then lift the right clamping arm, the left clamping arm is also lifted, and the left and right clamping shafts are aligned with the through holes at both ends of the pay-off reel. Then the clamping mechanism drives the left clamping arm to move towards the right clamping arm until the left and right clamping shafts are respectively inserted into both ends of the through hole and the pay-off reel is clamped. During the clamping process, the pay-off reel slides to the right on the rack through the sliding mechanism. The clamping end of the clamping shaft is conical in structure, which facilitates the insertion of the clamping shaft into the through hole.

[0025] When the left clamping arm is driven to move towards the right clamping arm by the clamping mechanism, the clamping motor drives the screw rod to rotate, and the sleeve on the screw rod moves to the right during the rotation of the screw rod, and the sleeve on the slide rod also moves to the right, that is, the left clamping arm moves towards the right clamping arm until the left and right clamping shafts clamp the pay-off reel. When the pay-off reel is clamped, the photovoltaic cable head on the pay-off reel is pulled out of the wire assembly, and then the driving assembly drives the right clamping shaft to rotate slowly, and the pay-off reel rotates and performs the pay-off operation, and the staff can perform a series of work of photovoltaic cable laying.

[0026] In the structure, Figure 4 , the wire assembly includes a H-shaped mounting seat 11, and two pairs of guide sleeves 12 are rotatably arranged on the mounting seat 11 and arranged in a cross shape. After the pay-off reel is installed, the photovoltaic cable head is pulled out of the wire assembly, and the wire assembly includes a mounting seat, and two pairs of guide sleeves arranged in a cross shape are arranged on the mounting seat. The guide sleeves serve as limiting and guiding, ensuring that the photovoltaic cable can smoothly pass through and remain stable during the pay-off process.

[0027] As a preferred structure, Figures 2-4 , the rack 1 is provided with a sliding mechanism, the sliding mechanism includes a support seat 13, and a left and right pair of support rods 14 are arranged on the support seat 13. A front and rear pair of rollers 15 are rotatably arranged on the support rods 14. The rack 1 is provided with a front and rear pair of cross beams 16, the support seat 13 is located between the two cross beams 16, and the rollers 15 are located on the corresponding cross beams 16.

[0028] In the illustration, the rear end of the rack 1 is also provided with a feeding seat 17, and the pay-off reel can be easily pushed onto the support seat through the feeding seat. The left and right ends of the support seat are both provided with the support rods, and a front and rear pair of rollers are arranged on the support rods. When the pay-off reel is pushed onto the support seat, the clamping arms are lifted, the clamping shafts are aligned with both ends of the through hole, and the left clamping arm moves to the right under the drive of the clamping mechanism, and the left clamping shaft is inserted into the through hole. The left clamping arm continues to move to the right, and the left clamping shaft pushes the pay-off reel to move to the right until the right clamping shaft is also inserted into the through hole, and the two clamping shafts clamp the pay-off reel.

[0029] During the above process, when the left clamping shaft pushes the pay-off reel to move to the right, the support seat slides to the right through the rollers. Driven by the support seat, the pay-off reel can move smoothly to the right, and the entire process will not damage the pay-off reel.

[0030] Furthermore, as a preferred structure, such as Figure 3 The drive assembly includes a double-layer sprocket 18 rotatably mounted on the right clamping arm 3, a shaft of the right clamping shaft 7 extending out of the right clamping arm 3 and having a rotating sprocket 19, a motor base 20 on the right clamping arm 3, a rotating motor 21 on the motor base 20, a drive sprocket 22 on the drive shaft of the rotating motor 21, and a chain 23 fitted between the drive sprocket 22 and one of the sprockets of the double-layer sprocket 18, and between the other sprocket of the double-layer sprocket 18 and the rotating sprocket 19.

[0031] In this structure, chains are fitted between the drive sprocket and one of the sprockets in the double-layer sprocket system, and between the other sprocket of the double-layer sprocket and the rotating sprocket on the right clamping shaft, forming a transmission chain to transmit the power of the rotary motor to the push shaft. When using this device for wire feeding, the rotary motor drives the drive sprocket to rotate, and under the linkage of the chains, the rotating sprocket drives the right clamping shaft to rotate. The wire feeding reel rotates, thus realizing the wire feeding action.

[0032] The left and right clamping arms are hollow inside, and multiple weight-reducing openings 24 are opened on both sides of the clamping arms. This design of the clamping arms reduces the weight of the clamping arms to a certain extent, making it easier for the clamping arms to be lifted.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
