[0032] Please refer to Figures 1 to 8, the wire pulley for distribution network provided by the present invention will be described below. A wire pulley for distribution network includes a hanging frame body 1, a guiding component 2 and an anti-detachment component 3. The hanging frame body 1 is installed on a cross arm, and a wire wheel 11 is arranged inside the hanging frame body 1; an inlet 12 for a cable 6 to enter the hanging frame body 1 is formed on one side of the hanging frame body 1, and the inlet 12 is located above the wire wheel 11; a sloping blocking surface 13 is formed at the lower end of the inlet 12, and the lower end of the blocking surface 13 faces the inside of the hanging frame body 1; a first guiding member 21 rotatably connected to the upper end of the inlet 12 is arranged on the guiding component 2, and a limiting surface 211 cooperating with the blocking surface 13 is formed at the lower end of the first guiding member 21; the guiding component 2 further includes a second guiding member 22 obliquely arranged on one side of the hanging frame body 1. The second guiding member 22 is located below the inlet 12, and the lower end of the second guiding member 22 is connected to the hanging frame body 1; an anti-detachment wheel 31 and an anti-detachment rod 32 are arranged on the anti-detachment component 3. The anti-detachment wheel 31 is arranged inside the hanging frame body 1 and is located above the wire wheel 11; the anti-detachment rod 32 penetrates through the anti-detachment wheel 31 and is rotatably connected to the anti-detachment wheel 31. The anti-detachment rod 32 has a degree of freedom to move in a direction close to or away from the wire wheel 11 along the side wall of the hanging frame body 1.
[0033] Compared with the prior art, the cable pulley for distribution network provided in this embodiment has the following features when in use. Since an inlet 12 for the cable 6 to enter the hanger body 1 is provided on one side of the hanger body 1, and the first guide member 21 of the guiding assembly 2 is rotatably connected to the upper end of the inlet 12. At the same time, the second guide member 22 of the guiding assembly 2 is inclined on the hanger body 1, and the lower end of the second guide member 22 is connected to the hanger body 1 and is located below the inlet 12. Therefore, when the unmanned aerial vehicle drives the cable 6 to move, by using the inclined second guide member 22, the cable 6 can be very conveniently dropped to the inlet 12. At the same time, as the unmanned aerial vehicle drives the cable 6 to move, the cable 6 pushes the first guide member 21 to rotate and opens the inlet 12, so that the cable 6 enters the hanger body 1. Since an inclined blocking surface 13 is provided at the lower end of the inlet 12, and the lower end of the blocking surface 13 faces the inside of the hanger body 1. At the same time, a limiting surface 211 matching the blocking surface 13 is provided at the lower end of the first guide member 21. Therefore, after the cable 6 enters the hanger body 1, by using the blocking surface 13 at the lower end of the inlet 12 and the limiting surface 211 at the lower end of the first guide member 21, the rotation of the first guide member 21 is restricted, so as to prevent the cable 6 from detaching from the hanger body 1 at the inlet 12. Since the anti-detachment assembly 3 is provided on the hanger body 1, and the anti-detachment wheel 31 is located above the wire wheel 11. At the same time, the anti-detachment rod 32 passes through the anti-detachment wheel 31 and is rotatably connected to the anti-detachment wheel 31, and the anti-detachment rod 32 has the freedom to move along the side wall of the hanger body 1 towards or away from the wire wheel 11. Therefore, after the cable 6 enters the hanger body 1 and drops into the groove of the wire wheel 11, the anti-detachment rod 32 is controlled to move downward and drive the anti-detachment wheel 31 to move, so that the anti-detachment wheel 31 presses on the cable 6. Thus, on the basis of not hindering the movement of the cable 6, the cable 6 is prevented from jumping out of the groove. In this way, by means of the second guide member 22 inclined below the inlet 12 to guide the cable 6 into the hanger body 1, and using the blocking surface 13 at the lower end of the inlet 12 and the limiting surface 211 at the lower end of the first guide member 21 to restrict the rotation of the first guide member 21, the cable 6 is prevented from detaching from the hanger body 1 at the inlet 12. At the same time, by means of the movement of the anti-detachment rod 32 on the anti-detachment assembly 3 on the hanger body 1, the anti-detachment wheel 31 is driven to press down on the cable 6, so as to prevent the cable 6 from jumping out of the groove on the basis of not hindering the movement of the cable 6.

[0037] Please refer to Figures 1 to 3As a specific embodiment of the wire-laying pulley for the distribution network provided by the present invention, a limit groove 321 is provided at one end of the anti-drop rod 32 close to the guide plate 212; the closing assembly 4 includes a closing rod 41 and a reset member 42; the closing rod 41 is arranged in the limit groove 321 and is slidably connected to the inner wall of the limit groove 321, one end of the closing rod 41 extends out of the limit groove 321 and is slidably connected to the bracket body 1; the reset member 42 is arranged in the limit groove 321 in a compressed state, and the two ends are respectively connected to the closing rod 41 is connected to the inner wall of the limiting groove 321, and the elastic force of the reset member 42 is greater than the elastic force of the elastic member 213; when the anti-drop rod 32 moves downward, it drives the closing rod 41 to move. When the closing rod 41 moves to a position in contact with the guide plate 212, the reset member 42 in a compressed state is reset, pushing the closing rod 41 to move, so that the closing rod 41 pushes the guide plate 212 to rotate, and then the limiting surface 211 contacts the blocking surface 13, thereby completely closing the entrance 12; the reset member 42 is a spring.

Therefore, when the wire wheel 11 rotates, the impurities adhered to the wheel groove first contact with the crushing roller 511, and the crushing roller 511 first crushes the impurities. As the wire wheel 11 rotates, the crushed impurities contact with the cleaning roller 521, and then the cleaning roller 521 cleans the crushed impurities, thereby ensuring the cleanliness of the wheel groove of the wire wheel 11.
