Description

Technical Field

[0001] The utility model belongs to the technical field of photovoltaic engineering, and particularly relates to a cable pay-off device for photovoltaic engineering. Background Art

[0002] During the construction of photovoltaic projects, cable laying is one of the core links, and its efficiency and quality are directly related to the progress and safety of the entire project.

[0003] However, the currently widely used cable pay-off method completely relies on manual direct pulling of the cable, which has the following defects:

[0004] The manual pulling method greatly increases the physical labor burden of workers. Long-term and high-intensity pulling operations not only quickly consume the physical strength of workers, resulting in a significant decline in work efficiency, but also may lead to a decline in work quality due to excessive fatigue, such as uneven cable laying and rough joint treatment, thus affecting the performance and lifespan of the entire photovoltaic system.

[0005] Manually pulling the cable requires extremely high physical strength from workers and a relatively large force needs to be continuously applied during the operation. In a complex and changeable outdoor construction environment, such as uneven, slippery or obstacle-ridden ground, workers are extremely likely to fall, sprain or other safety accidents due to uneven force application or loss of balance, seriously threatening the personal safety and health of workers.

[0006] Therefore, in order to solve the above problems, it is necessary to design a cable pay-off device for photovoltaic engineering. Content of the Utility Model

[0007] The purpose of the utility model is to provide a cable pay-off device for photovoltaic engineering to solve the technical problem that the existing pay-off device requires manual pulling.

[0008] To solve the above technical problem, the utility model provides a cable pay-off device for photovoltaic engineering, including:

[0009] Two symmetrically arranged roller seats, each roller seat is connected with a driving roller and a driven roller through bearings;

[0010] A cable reel, arranged on the supporting surface formed by two pairs of driving rollers and driven rollers;

[0011] A rotating shaft, the two ends of which are respectively connected with the driving rollers on the two roller seats;

[0012] A motor, connected with the rotating shaft to be suitable for driving the rotating shaft to rotate; where

[0013] The rotating shaft is suitable for driving the two driving rollers to rotate when rotating, so as to drive the cable reel and the two driven rollers to rotate and make the cable reel pay off the cable.

[0014] Furthermore, a first gear is sleeved on the rotating shaft;

[0015] A second gear is provided on the motor; wherein

[0016] The first gear and the second gear are meshed with each other; and

[0017] The motor is adapted to drive the rotating shaft to rotate through the second gear and the first gear.

[0018] Furthermore, a connecting plate is provided between the two roller seats; wherein

[0019] The connecting plate is connected to the two roller seats; and

[0020] The motor is fixed on the connecting plate.

[0021] Furthermore, bases are provided on both sides of the cable reel;

[0022] At least one cushion block is provided above the base;

[0023] A jack is provided on the top of the cushion block;

[0024] A support block is provided on the top of the jack;

[0025] The same support column is provided on the tops of the two support blocks; wherein

[0026] The support column penetrates through the cable reel; and

[0027] The two jacks are adapted to drive the two support blocks to move upward so as to lift the cable reel by the support column.

[0028] Furthermore, a placing portion is provided on the top of the support block; wherein

[0029] The support column is adapted to be placed in the placing portion.

[0030] Furthermore, two guiding columns are provided on the top of the base; wherein

[0031] A sliding sleeve is sleeved on the guiding column; and

[0032] The sliding sleeve is slidably connected to the guiding column;

[0033] Both ends of the support block are connected to the two sliding sleeves.

[0034] The beneficial effects of the utility model are:

[0035] (1) When wire laying is required, start the motor. The second gear on the motor meshes with the first gear on the rotating shaft. As the motor rotates, the second gear drives the first gear to rotate, thereby transmitting the rotational power of the motor to the rotating shaft. Driven by the gear drive, the rotating shaft starts to rotate, and then drives the driving rollers on the two roller seats to rotate. Since there is a certain frictional force between the driving rollers and the cable reel, the rotation of the driving rollers will drive the cable reel, the driven rollers, and the cable to rotate together. As the cable reel rotates, the cable gradually unwinds from the cable reel, thus achieving automatic wire laying, reducing the time and physical effort of manual operation, and significantly improving construction safety.

[0036] (2) When it is necessary to lift the cable reel for wire laying, select a suitable cushion block and place the jack on the cushion block. At this time, control the jack to push the support block upward. The support block drives the sliding table to move upward along the guide post, and the support block drives the support column to move upward together. The support column lifts the cable reel. At this time, place the roller seat and the driving rollers and driven rollers on the roller seat under the cable reel. Then control the jack to reset so that the cable reel falls on the driving rollers and driven rollers, and the wire laying operation of the cable can be carried out, thus achieving convenient lifting of the cable reel, reducing the labor intensity of workers and reducing the installation time, and improving the construction efficiency.

Embodiment 1

[0046] As Figure 1 、 Figure 3 shown, this embodiment provides a wire releasing device for a photovoltaic project cable, including:

[0047] Two symmetrically arranged roller seats 1, and a driving roller 2 and a driven roller 3 are connected to each roller seat 1 by bearings; a cable reel 4 is arranged on the supporting surface formed by two pairs of driving rollers 2 and driven rollers 3; a rotating shaft 5, the two ends of which are respectively connected to the driving rollers 2 on the two roller seats 1; a motor 6, connected to the rotating shaft 5 to drive the rotating shaft 5 to rotate; wherein the rotating shaft 5 is adapted to drive the two driving rollers 2 to rotate when rotating, so as to drive the cable reel 4 and the two driven rollers 3 to rotate, and to release the cable on the cable reel 4; wherein the roller seat 1 is also used to limit the cable reel 4 to prevent the cable reel 4 from falling off the rollers.

[0048] A first gear 7 is sleeved on the rotating shaft 5; a second gear 8 is arranged on the motor 6; wherein the first gear 7 and the second gear 8 are meshed with each other; and the motor 6 is adapted to drive the rotating shaft 5 to rotate through the second gear 8 and the first gear 7.

[0049] A connecting plate 9 is arranged between the two roller seats 1; wherein the connecting plate 9 is connected to the two roller seats 1; and the motor 6 is fixed on the connecting plate 9; by arranging the connecting plate 9, the stability of the two roller seats 1 is increased, and at the same time, it also serves as an installation platform for the motor 6, so that the second gear 8 on the motor 6 can be perfectly meshed with the first gear 7.

[0050] In this embodiment, when wire laying is required, the motor 6 is started. The second gear 8 on the motor 6 meshes with the first gear 7 on the rotating shaft 5. As the motor 6 rotates, the second gear 8 drives the first gear 7 to rotate, thereby transmitting the rotational power of the motor 6 to the rotating shaft 5. The rotating shaft 5 starts to rotate under the drive of the gear transmission, and then drives the driving rollers 2 on the two roller seats 1 to rotate. Since there is a certain frictional force between the driving rollers 2 and the cable reel 4, the rotation of the driving rollers 2 will drive the cable reel 4, the driven rollers 3 and the cable to rotate together. As the cable reel 4 rotates, the cable gradually unwinds from the cable reel 4, thus achieving automatic wire laying, reducing the time and physical consumption of manual operation, and significantly improving the construction safety.

The support block 13 drives the sliding table 16 to move upward along the guiding column 15, and the support block 13 drives the support column 14 to move upward together. The support column 14 lifts the cable reel 4. At this time, place the roller seat 1 and the driving roller 2 and the driven roller 3 on the roller seat 1 under the cable reel 4. Then control the jack 12 to reset so that the cable reel 4 falls on the driving roller 2 and the driven roller 3, and the wire laying operation of the cable can be carried out.
