The components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0024] In the description of the present invention, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" that may appear should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components.

[0025] In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the term "provided with" that may appear should be understood in a broad sense. For example, the object "provided with" may be a part of the body, or may be arranged separately from the body and connected to the body, and the connection may be a detachable connection or an inseparable connection. For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0026] The present invention is further described in detail below in conjunction with the embodiments.

[0027] Specific embodiments of the low-voltage cable laying device provided by the utility model:

[0028] This embodiment is specifically applied to the construction of 2×240 low-voltage cables for photovoltaic power generation. Through the construction of this device, the number of workers required to lay 2×240 low-voltage cables can be greatly reduced; the phenomenon of cable spacing not meeting specifications and design requirements can be reduced; the first-time acceptance rate of 2×240 low-voltage cables can be increased, and the construction progress of subsequent cable laying, brick covering, and backfilling can be accelerated.

[0029] See also Figure 1-5 The low-voltage cable laying device includes a steel wire 3, a drum 2 for winding the steel wire 3, a power device 1 for driving the drum 2 to rotate, a plurality of cable pay-off pulleys 4 for supporting the cable, and a clamping member 5 for clamping the end of the cable, wherein the clamping member 5 is connected to the end of the steel wire 3.

[0030] In this embodiment, the power device 1 includes a motor and a reducer, the motor drives the reducer to operate, the output end of the reducer is connected to the reel 2, and drives the reel 2 to rotate and reel the wire 3. In some other embodiments, the power device 1 can use an engine instead of the motor and the reducer.

[0031] The reel 2 reels the steel wire 3 and drives the clamping member 5 to move, so that the cable body 6 is released from the cable reel 7 and moves along the cable pay-off pulley 4; in some embodiments, the cable reel 7 can be placed on a cable pay-off rack so that the cable reel 7 can rotate freely as the cable body 6 is released.

[0032] The clamping member 5 includes a conical portion 51 and a clamping portion for clamping the cable. The small end of the conical portion 51 is connected to the steel wire 3 by welding, and the clamping portion is connected to the large end of the conical portion 51. The outer diameter of the clamping portion is not greater than the outer diameter of the large end of the conical portion 51.

[0033] Several cable pay-off pulleys 4 are evenly arranged to support the cable body 6 during the pay-off process of the cable body 6 to prevent the cable body 6 from rubbing against the ground; however, if the steel wire 3 is directly tied to the end of the cable body 6, the end of the cable body 6 is prone to get stuck when passing through the cable pay-off pulley 4. Due to the presence of the conical portion 51, when the clamp 5 pulls the end of the cable body 6 out of the cable reel 7 and passes through the cable pay-off pulley 4, the conical portion 51 can drive the end of the cable body 6 to pass through the cable pay-off pulley 4 smoothly, preventing the end of the cable body 6 from getting stuck at the cable pay-off pulley 4.

[0034] The clamping part includes a cylindrical seat 52, which is connected to the large end of the conical part 51. The outer ring side of the cylindrical seat 52 is rotatably connected to a rotating ring 53. The middle part of the cylindrical seat 52 is uniformly circumferentially and slidably penetrated with a plurality of radial T-shaped clamping bodies 54. The cylindrical seat 52 is provided with holes for the T-shaped clamping bodies 54 to pass through. An annular plate 55 is provided on the inner side of the rotating ring 53. The annular plate 55 is provided with arc grooves 56 corresponding to the T-shaped clamping bodies 54 one by one. The distances from the two ends of the arc groove 56 to the center of the annular plate 55 are different, thereby driving the T-shaped clamping body 54 to move radially. The outer end of the T-shaped clamping body 54 extends into the corresponding arc groove 56.

[0035] There are two annular plates 55, which are symmetrical to the two sides of the T-shaped clamping body 54. The outer ends of the T-shaped clamping body 54 extend into the arc grooves 56 of the two annular plates 55. In this embodiment, there are four T-shaped clamping bodies 54, and four arc grooves 56 are provided on each annular plate 55.

[0036] In order to facilitate the rotation of the swivel 53, the T-shaped clamping body 54 can tightly clamp the end of the cable body 6. The swivel 53 is in the shape of a hexagonal prism with a central hole, and the swivel 53 can be driven to rotate by a wrench, thereby driving the T-shaped clamping body 54.

[0037] A positioning column 57 is passed through the cylindrical seat 52. A hole is provided on the cylindrical seat 52 for the positioning column 57 to pass through. The cross-section of the positioning column 57 is T-shaped. A spring 58 is connected between the outer end of the positioning column 57 and the cylindrical seat 52. Two positioning holes 59 cooperating with the positioning column 57 are provided on one side of the rotating ring 53. The positioning column 57 cooperates with the two positioning holes 59 respectively so that the outer ends of the T-shaped clamping body 54 are respectively located at the two ends of the arc groove 56.

[0038] In order to enhance the clamping effect on the end of the cable body 6, the inner end of the T-shaped clamping body 54 is tapered so that the inner end of the T-shaped clamping body 54 extends into the end of the cable body 6 to improve the clamping stability.

[0039] When the cable body 6 is connected to the clamping member 5, the end of the cable body 6 is extended into the cylindrical seat 52, and the positioning column 57 is pulled outward so that the positioning column 57 overcomes the elastic force of the spring 58 and disengages from the first positioning hole 59. The swivel 53 is rotated, and the arc groove 56 causes the T-shaped clamping body 54 to move radially inward along the cylindrical seat 52. The inner end of the T-shaped clamping body 54 clamps the cable body 6, and the positioning column 57 corresponds to the other positioning hole 59. The spring 58 causes the positioning column 57 to enter the positioning hole 59, so that the T-shaped clamping body 54 is positioned.

[0040] Finally, it should be noted that the above is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments without creative work, or replace some of the technical features therein with equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
