Description

Technical Field

[0001] This invention relates to the field of cable laying device technology, and in particular to a photovoltaic power generation cable laying device. Background Technology

[0002] Cable laying refers to the process of laying and installing cables along a surveyed route to form a cable line. Depending on the application, it can be divided into several laying methods, such as overhead, underground (pipe and direct burial), underwater, wall, and tunnel. The rational selection of cable laying method is very important for ensuring the transmission quality, reliability, construction and maintenance of the line. Long-distance communication cables are generally laid directly to ensure their communication security and reliability. Urban trunk cables (relay and user trunk cables) are generally laid in ducts to ensure their communication security and reliability, convenient installation and replacement, and urban aesthetics. Urban distribution cables can be laid overhead or in walls. With the development of modern urban construction, duct laying will gradually replace cable laying.

[0003] When laying existing cables, the cable reel is placed on the laying device for fixation, which also facilitates the cable being pulled out of the reel for laying and reduces the difficulty of pulling the cable. For example, Chinese Patent Publication No. CN220684292U discloses "a cable laying device", which provides support force to the take-up reel through a bearing ring. Rotating the cutting turntable can make the opening of the bearing ring face the guide block, thereby releasing the lock on the take-up reel. Applying a horizontal thrust can push the take-up reel away from the frame along the guide block. The take-up reel and the frame are detachably connected, which reduces the difficulty of replacing the take-up reel.

[0004] However, in actual use, cables are laid in a variety of situations, such as overhead, underground (pipes and direct burial), underwater, walls and tunnels, etc. The required laying height of the cable is also different. The angle of the cable led out by the traction structure of the laying device is difficult to change and cannot adapt to the needs of different fields. This can easily lead to the cable bending and being damaged during the laying process. At the same time, it can also cause great resistance to the cable traction during the laying process, affecting the laying of the cable and easily scratching the surface of the cable. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the difficulty in changing the angle of the cable drawn out by the traction structure of the laying device, which makes it impossible to adapt to the needs of different fields, easily leading to cable damage when bending, increasing the cable's traction resistance, affecting cable laying, and easily scratching the cable's surface. Therefore, this invention proposes a photovoltaic power generation cable laying device.

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0030] Reference Figure 1-7 A photovoltaic power generation cable laying device includes a mounting frame 1 and an unwinding roller 3 for winding cable 2. The unwinding roller 3 is rotatably mounted on the mounting frame 1. The mounting frame 1 is provided with a guide mechanism that cooperates with the cable 2. The guide mechanism includes a guide component 4 and an angle adjustment component 5.

[0031] The guide assembly 4 includes a guide frame 41, a guide wheel 42 is provided inside the guide frame 41, the cable 2 passes through the guide frame 41 and the angle adjustment assembly 5, the guide wheel 42 is in contact with the cable 2, the angle adjustment assembly 5 is provided with a guide wheel 6 that cooperates with the cable 2, and the mounting frame 1 is provided with a drive mechanism 7 that is poweredly connected to the unwinding roller 3.

[0032] In this invention, the cable is guided by the guide component 4 and supported by the guide wheel 6. The height of the guide wheel 6 is adjusted by the angle adjustment component 5 to change the cable lead-out angle, thereby adapting to different laying occasions and improving the applicability of the laying device. The drive mechanism 7 provides rotational power to the cable reel, reducing the power required to pull the cable out, thus facilitating cable laying.

[0033] Furthermore, in this embodiment, a mounting frame 43 is provided on the guide frame 41, and a limiting wheel 44 is provided inside the mounting frame 43. The cable 2 passes between the guide wheel 42 and the limiting wheel 44. By setting the limiting wheel 44 to cooperate with the guide wheel 42, the cable 2 is auxiliaryly clamped to prevent the cable 2 from separating from the groove on the guide wheel 6.

[0034] In this embodiment, a spring 45 is provided between the guide frame 41 and the mounting frame 43. A guide rod 46 is fixedly provided on the mounting frame 43, and a pulley is fixedly provided on the guide frame 41. A groove 47 that cooperates with the pulley is provided on the mounting frame 1. When the unwinding roller 3 rotates, the position of the cable wound on it will also change. At this time, under the action of the pulley and the groove 47, the guide frame 41 can move along the corresponding position of the groove, thereby avoiding excessive friction between different layers of the cable and causing wear. The guide wheel 6 will also change its position accordingly as the guide frame 41 moves.

[0035] Furthermore, in this embodiment, the angle adjustment component 5 includes a guide frame 51 that cooperates with the guide wheel 6. An extension arm 52 that is rotatably connected to the guide frame 51 is fixedly provided on the mounting frame 1. The mounting frame 1 and the extension arm 52 are rotatably connected, so that the position of the guide frame 51 and the guide wheel 6 can be adjusted as needed, thereby changing the angle at which the cable is led out. At the same time, it can also provide a buffer for the cable support, forming an arc-shaped structure to prevent the cable from bending and breaking directly with the guide frame 41.

[0036] It should be noted that, in this embodiment, a ratchet portion 53 is fixedly provided on the guide frame 51, and a through groove that mates with the ratchet portion 53 is provided on the extension arm 52. A mounting ring 54 is fixedly provided in the through groove, and a pawl 55 that mates with the ratchet portion 53 is rotatably provided on the mounting ring 54. A torsion spring is provided between the pawl 55 and the mounting ring 54. The torsion spring applies force to the pawl 55, so that the pawl 55 always remains in contact with the ratchet portion 53. When the guide frame 51 rotates upward, the pawl 55 will not interfere with the rotation of the ratchet portion 53. When the guide frame 51 moves downward, the pawl 55 will engage with the groove on the ratchet portion 53, restricting the rotation of the ratchet portion 53, and thus restricting the downward rotation of the guide frame 51.

[0037] In this embodiment, a drive ring 56 is rotatably disposed in the through groove. The drive ring 56 is fixedly provided with a protrusion that cooperates with a plurality of pawls 55. When the drive ring 56 rotates counterclockwise, the protrusion on the drive ring 56 will contact the pawls 55 and apply force to the pawls 55 to separate them from the ratchet part 53, so as not to interfere with the rotation of the ratchet part 53. At this time, the guide frame 51 can be rotated up and down at will to adjust the angle. It can also be folded to reduce the space required for the laying device, making it convenient for transportation and storage.

[0038] Furthermore, in this embodiment, a rotating disk 57 is fixedly provided on one side of the drive ring 56, and a force-applying rod 58 is fixedly provided on the rotating disk 57. A moving groove that cooperates with the force-applying rod 58 is provided on the extension arm 52. By providing the force-applying rod 58, it is convenient to rotate the rotating disk 57 to drive the drive ring 56 to rotate. By providing the moving groove, the range of movement of the force-applying rod 58 is limited to prevent the protrusion on the drive ring 56 from being misaligned with the pawl 55 due to excessive movement.

[0039] In detail, in this embodiment, the drive mechanism 7 includes a reducer 71 mounted on the mounting frame 1. The output shaft of the reducer 71 is poweredly connected to the unwinding roller 3. A drive motor is mounted on the reducer 71. The drive motor provides power to the reducer 71, thereby driving the unwinding roller 3 to rotate and unwind the cable, which facilitates the laying of the cable.

[0040] In this embodiment, the drive mechanism 7 also includes a handwheel 72 rotatably mounted on the mounting frame 1. The output shaft of the handwheel 72 is poweredly connected to the unwinding roller 3. The handwheel 72 is designed to facilitate manual rotation to adapt to laying sites without power.

[0041] More specifically, in this embodiment, a bolt 73 is threaded onto the handwheel 72, and a transmission component 74 is threaded onto the bolt 73. A guide groove corresponding to the transmission component 74 is provided on the handwheel 72. The transmission component 74 is inserted into the unwinding roller 3. The movement of the transmission component 74 can be controlled by rotating the bolt 73. When the transmission component 74 is separated from the unwinding roller 3, the unwinding roller 3 can be removed and replaced.

[0042] Working method: During operation, the drive motor provides power to the reducer 71, thereby driving the unwinding roller 3 to rotate and unwind the cable. The cable 2 passes through the guide wheel 42 and the limit wheel 44, and finally leads out along the guide wheel 6 for easy laying. During this process, the guide frame 51 cooperates with the guide wheel 6 to provide cable support and buffer, forming an arc structure to prevent the cable from bending and breaking.

[0043] By applying force to the force bar 58, the rotating disk 57 and the drive ring 56 are driven to rotate. The protrusion on the drive ring 56 will contact the pawl 55, and force will be applied to the pawl 55 to separate it from the ratchet part 53, so as not to interfere with the rotation of the ratchet part 53. At this time, the guide frame 51 can be rotated up and down at will to adjust the angle. It can also be folded to reduce the space required for the laying device, making it convenient for transportation and storage.

[0044] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
