The upper supporting block 205 is supported by the limiting frame 211, the cable 103 is prevented from loosening due to the overlong sliding distance of the upper supporting block 205, and continuous force is provided for the limiting frame 211 by the positioning spring 210 and the positioning slide rod 209, so that the upper supporting block 205 can be reset after sliding conveniently.
Example 5: referring to fig. 1-13, a power distribution network planning device based on a power distribution network frame is basically the same as that in embodiment 1, and further, a fixing frame 501 is fixedly connected to a parallel rod 3, a wire wheel 5 is rotatably arranged on the fixing frame 501, a pull rope 502 is arranged on the wire wheel 5, and one end of the pull rope 502 is fixedly connected to a limit post 403.
The wire wheel 5 is internally provided with a friction cavity 503, the friction cavity 503 is internally provided with a first sleeve 504, the first sleeve 504 is fixedly connected with the fixing frame 501, a first sliding rod 505 is hermetically sliding in the first sleeve 504, a friction block 508 is arranged on the first sliding rod 505, and a first spring 506 is fixedly connected between the first sliding rod 505 and the first sleeve 504.
When the spacing post 403 breaks away from in the parallel pole 3, spacing post 403 pulls stay cord 502 and moves down, supports counterweight support 4, and when the stay cord 502 of winding on reel 5 moves down, drive reel 5 rotates, through friction block 508 with the inner wall friction of friction cavity 503, prevents effectively that reel 5 rotational speed is too fast to prevent cable 103 from moving down fast and last supporting shoe 205 friction, and then prevent effectively that cable 103 from accomodating the friction fracture.
Example 6: referring to fig. 1-13, a power distribution network planning device based on a power distribution network frame is basically the same as that of embodiment 1, and further, a second spring 507 is fixedly connected between a friction block 508 and a first sliding rod 505, a sealing rod 302 slides in a parallel rod 3 in a sealing manner, an air inlet pipe 509 communicated with a first sleeve 504 is arranged in a fixing frame 501, and a second connecting pipe 510 is arranged between the air inlet pipe 509 and a first sliding cavity 301.
When the fixed rope 602 pulls the sealing rod 302 to slide, the gas in the first sliding cavity 301 enters into the first sleeve 504 through the second connecting pipe 510, so that the first sliding rod 505 slides downwards, at this time, the pressure between the friction block 508 and the inner wall of the friction cavity 503 is reduced, the friction force is reduced, and the rotating speed of the wire wheel 5 is relatively high.
When the cable 103 to be stored is long, the pressure of the cable 103 to the mounting ring 601 is large, at this time, the distance that the sealing rod 302 slides outwards is long, so that the air pressure in the first sliding cavity 301 and the first sleeve 504 rises, and the friction force between the friction block 508 and the inner wall of the friction cavity 503 is relatively low.
When the cable 103 to be stored gradually gets shorter, the gravity of the cable 103 gradually decreases, the sealing rod 302 is pushed to slide into the first sliding cavity 301 under the action of the limiting spring 303, the air pressure in the first sliding cavity 301 and the air pressure in the first sleeve 504 gradually decrease, the first spring 506 pushes the first sliding rod 505 to reset upwards, so that the friction force between the friction block 508 and the inner wall of the friction cavity 503 gradually increases, at this time, the rotating speed of the wire wheel 5 decreases, and the downward moving speed of the cable 103 is reduced by the counterweight bracket 4.
When the cable 103 to be stored reaches the set height, the air pressure in the first sliding cavity 301 gradually returns to the initial air pressure value, and the first sliding rod 505 slides upwards under the action of the first spring 506, so that the friction force between the friction block 508 and the inner wall of the friction cavity 503 reaches the maximum value, the wire wheel 5 is fixed, and the weight support 4 does not move downwards any more.
Through the corresponding relation between the rotating speed of the wire wheel 5 and the weight of the wire 103, the longer wire 103 to be received can be quickly received, the wire wheel 5 is gradually decelerated along with the gradual shortening of the length of the wire 103 to be received until the set value is reached, and the wire wheel 5 is fixed, so that the end part of the broken wire 103 is effectively prevented from sliding out of the mounting groove 202 and contacting the ground again, and further, the safety accident caused by the long-time step voltage is effectively prevented.

When the sealing rod 302 slides out, the limit post 403 slides out, and then, in combination with the relationship between the length of the cable 103 to be received and the sliding length of the sealing rod 302 in embodiment 6, after the length of the cable 103 to be received reaches the set value, the sealing rod 302 slides in the direction of the sealing plate 307 under the action of the limit spring 303, at this time, since the set distance of the cable 103 to be received is shorter, the sliding distance of the sealing rod 302 into the parallel rod 3 is greater than the initial distance, the groove 305 clamps the pull rope 502 and slides into the fixing groove 308, and cooperates with the fixing groove 308 to clamp the pull rope 502, thereby effectively fixing the pull rope 502 and preventing the end of the broken cable 103 from falling down due to continuous descent of the weight support 4.
Example 8: referring to fig. 1-13, a power distribution network planning apparatus based on a power distribution network frame is substantially the same as embodiment 1, and further, a second sliding cavity 306 is disposed between a sealing plate 307 and a parallel rod 3, a first connecting pipe 213 is fixedly connected between the second sliding cavity 306 and a positioning sleeve 208, and a fixed spring 309 is disposed between the sealing plate 307 and the second sliding cavity 306.
After the limiting pin 304 enters the groove 305, pressure is continuously applied to the sealing plate 307, the sealing plate 307 slides into the second sliding cavity 306 and is buffered through the fixing spring 309, and therefore the stay cord 502 is effectively prevented from being excessively clamped and broken.
When the sealing plate 307 slides into the second sliding cavity 306, the gas in the second sliding cavity 306 is compressed, and the gas in the second sliding cavity 306 enters into the positioning sleeve 208 through the first connecting pipe 213, so that the positioning slide rod 209 drives the limiting frame 211 to slide towards the upper supporting block 205, and at this time, the upper supporting block 205 continuously moves upwards when sliding, so as to clamp and fix the cable 103, and further effectively prevent the head of the broken cable 103 from falling.
