Specific embodiments

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0028] In the description of the present invention, it should be noted that, unless otherwise clearly defined and limited, the terms "installation", "connection", and "connection" 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 also be directly connected, or indirectly connected through an intermediate medium, and can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0029] Embodiment 1:

[0030] This embodiment provides a wire-releasing device for facilitating wire-end fixing in wind power operation construction, specifically as Figures 1-6 shown, including a wire-releasing frame 101 and a wire-end fixing component 2 for fastening the wire end. A wire-releasing disc is installed on the wire-releasing frame 101. The wire-releasing disc includes a wire-releasing shaft 104 and wire-releasing side plates 105 respectively installed at both ends thereof; mounting holes 112 are provided on the wire-releasing side plates 105, and the wire-end fixing component 2 is embedded in any one of the mounting holes 112.

[0031] The wire-end fixing assembly 2 includes a knob 201 and a knob base 202. The knob 201 is threadedly connected to the knob base 202. An installation base 206 is mounted on the knob base 202. A plurality of clamping claws 205 are rotatably connected to the installation base 206. A wedge surface is provided at one end of the clamping claw 205 away from the installation base 206. A wedge surface cooperating with the clamping claw 205 is provided at one end of the knob 201 close to the installation base 206.

[0032] The staff inserts the wire end through the through hole in the knob base 202, and then the wire end passes through the installation base 206 and a plurality of clamping claws 205 in sequence, and then is in the through hole of the knob 201. When the staff sees the wire end in the knob 201, they start to rotate the knob 201, so that the knob 201 is screwed into the knob base 202. During this process, the wedge surface of the knob 201 presses the wedge surface of the clamping claw 205, so that the clamping claw 205 clamps and fixes the wire end inserted between the clamping claws 205. After the fixing is completed, the staff starts to rotate the wire-releasing side plate 105 to wind up the cable. At this time, the knob 201 will not be blocked by the wire-releasing frame 101 during the rotation of the wire-releasing side plate 105. If the staff does not clamp and fix the wire end, that is, when the knob 201 is not screwed into the knob base 202, the overall length of the wire-end fixing assembly 2 is longer at this time. Therefore, the knob 201 will be blocked by the wire-releasing frame 101 due to hitting the wire-releasing frame 101 during the rotation of the wire-releasing side plate 105, and at this time, the wire-releasing side plate 105 cannot wind up or release the cable.

[0033] Through the above settings, only after the wire end is fixed can the wire-releasing disc rotate freely, which can avoid the staff forgetting to fix the wire end and prevent the wire end from popping out and hurting people during subsequent wire release; at the same time, the wire-end fixing assembly 2 is arranged on the side of the wire-releasing side plate 105, which is more convenient and faster for the staff to perform the fixing operation.

[0034] Embodiment 2:

[0035] On the basis of Embodiment 1, this embodiment further expands the wire-end fixing assembly 2, specifically as Figures 3-5 shown. A second spring 203 is mounted on the knob base 202. The second spring 203 is mounted on the wire-releasing side plate 105, and the knob base 202 slides in the mounting hole 112.

[0036] If a few staff members, for the sake of convenience, directly screw the knob 201 into the knob base 202 without clamping and fixing the wire head, since the wire head does not pull the wire head fixing component 2 at this time, under the action of the second spring 203, the knob 201 and the knob base 202 will still be ejected, and at this time the wire release frame 101 will still block the knob 201. If the wire head is fastened, then when winding the cable, the cable itself will automatically pull the wire head fixing component 2, causing the knob base 202 to retract into the mounting hole 112 against the elastic force of the second spring 203. At this time, the wire release side plate 105 will not block the knob 201 when rotating.

[0037] Through the above settings, when the staff winds the cable, they must fix the wire head, otherwise they will not be able to wind the cable, thereby further ensuring that the wire head will not pop out and hurt people during subsequent wire release.

[0038] Other parts of this embodiment are the same as those of the above embodiment and will not be described in detail.

[0039] Embodiment 3:

[0040] This embodiment is further expanded on the basis of Embodiment 2, specifically as Figure 7 shown, a plurality of fitting holes 111 are provided on the wire release shaft 104, a plurality of fitting pins 109 are slidably connected to the wire release frame 101, a first spring 110 is provided between the fitting pins 109 and the wire release frame 101, and the knob 201 forms a fit with the fitting pins 109.

[0041] When the wire head is not clamped and fixed, the knob 201 will be blocked by the knob 201. At this time, the knob 201 will press the fitting pin 109, and the fitting pin 109 will retract against the elastic force of the first spring 110. When the fitting pin 109 retracts, it will be embedded in the fitting hole 111, thereby making the wire release shaft 104 unable to rotate.

[0042] Through the above settings, when the wire release disc is forced to stop rotating, the wire head fixing component 2 that originally bears the load is changed to the fitting pin 109, thereby improving the service life of the wire head fixing component 2; and the fitting pin 109 is closer to the rotation center of the wire release shaft 104, that is, the load borne by the fitting pin 109 is relatively smaller.

[0043] Other parts of this embodiment are the same as those of the above embodiment and will not be described in detail.

[0044] Embodiment 4:

[0045] This embodiment further expands the wire head fixing component 2 on the basis of Embodiment 1, specifically as Figures 3-4 shown, anti-slip lines 204 are provided on the knob 201.

[0046] By setting the anti-slip pattern 204, the friction between the knob 201 and the hand of the operator can be increased, facilitating the operator to perform the operation of locking the wire end.

[0047] Other parts of this embodiment are the same as those of the above embodiment and will not be described in detail.

[0048] Embodiment 5:

[0049] This embodiment is further extended on the basis of Embodiment 1, specifically as Figure 1 shown, a guiding frame 103 is installed on the wire pay-off rack 101, a guiding slider 107 is slidably connected to the guiding frame 103, and a through hole is provided on the guiding slider 107.

[0050] Pass the cable through the through hole on the guiding slider 107. When the cable is wound and unwound on the pay-off reel, the guiding slider 107 slides left and right on the guiding frame 103 to guide the cable, enabling it to be wound and unwound regularly and preventing the cable from knotting.

[0051] Other parts of this embodiment are the same as those of the above embodiment and will not be described in detail.

[0052] Embodiment 6:

[0053] This embodiment is further extended on the basis of Embodiment 5, specifically as Figure 8 shown, a cleaning brush 108 is provided in the through hole of the guiding slider 107.

[0054] Through the above setting, when the cable is wound, the cleaning brush 108 will clean the dirt and other impurities adhering to the surface of the cable, improving the cleanliness of the cable.

[0055] Other parts of this embodiment are the same as those of the above embodiment and will not be described in detail.

[0056] Embodiment 7:

[0057] This embodiment further extends the pay-off reel on the basis of Embodiment 1, specifically as Figure 1 shown, a lifting hole 106 is provided on the wire pay-off side plate 105.

[0058] When lifting is required, pass the lifting rope through the lifting hole 106 and fix it. After lifting this device, it is convenient for aerial wire pay-off operation.

[0059] Other parts of this embodiment are the same as those of the above embodiment and will not be described in detail.

[0060] Embodiment 8:

[0061] This embodiment is further extended on the basis of Embodiment 1, specifically as Figure 1 shown, a plurality of universal wheels 102 are installed on the wire pay-off rack 101.

[0062] When on the ground, it is convenient for the staff to push the wire reel 101 for short-distance movement.

[0063] Other parts of this embodiment are the same as those of the above embodiment and will not be described in detail.

[0064] The above are only the preferred embodiments of the present invention, and do not impose any form of limitation on the present invention. Any simple modification or equivalent change made to the above embodiments based on the technical essence of the present invention falls within the protection scope of the present invention.
