The working principle of the cable damage detection device is as follows: the application is installed on the cable when the cable is laid, in particular, one end of the cable can be inserted into the cylinder 1 when the cable is laid, and the cable sequentially passes through the two groups of driving mechanisms 27, and the cable is positioned between the three driving wheels 21 of the same group of driving mechanisms 27. In normal use, the bin door 13 is fixedly connected with the battery bin 2 through bolts, the charging wire 7 is completely contained on the take-up pulley 6, the charging head 8 is positioned in the battery bin 2, and the through hole 14 is completely shielded by the baffle 17. The control mechanism comprises a control module and a positioning module.

When the application is used, the second forward and reverse rotation motor 23 rotates in the same direction at the same time, the gear 24 is driven to rotate, the meshed racks 22 rotate, all driving wheels 21 are driven to rotate in the same direction at the same time, the driving wheels 21 roll along the cable, the cylinder 1 is driven to move along the cable, when the cylinder 1 moves to one end of the cable, the connecting part of the cable and the electric tower is touched, the push switch 25 is triggered at the moment, the push switch 25 sends a signal to a control module in the control mechanism 26, and the control module controls the second forward and reverse rotation motor 23 to rotate in the opposite direction at the moment, so that the cylinder 1 runs to the other end of the cable. The above steps are repeated and the drum 1 can be moved back and forth over the cable.

The distance measuring sensor 20 is able to measure the distance between itself and the outer skin of the aligned cable as the drum 1 moves back and forth over the cable, and the positioning module sends the geographical location where the drum 1 is currently located to the server when the distance measuring sensor 20 detects a sudden change in data.

Due to the influence of external environments such as strong wind, the shaking of the cable may cause the change of the measurement data of the ranging sensor 20 and trigger the positioning module to send the position, and for the error caused by the situation, the solution is as follows: since the cylinder 1 reciprocates on the cable, the same position is detected at intervals of a certain time, if the cable is intact, the number of times of detection of the abnormality is necessarily smaller than that of the actual breakage, so that the worker can set a threshold value of the number of times of recording, and the position where the number of times of recording reaches the threshold value is determined as the breakage position, thereby filtering the error. Meanwhile, the number of times of recording can reflect the damage degree, namely, the more the number of times of recording the recorded position is, the longer the damage time of the position is proved, and the greater the damage degree is. Because the outer skin of the long-distance cable is generally thicker, the cable is slightly damaged, the maintenance is not required to be carried out by using manpower, and whether the cable needs to be maintained or not can be judged by recording the times.

In sunny days, the solar panel 19 may generate electricity to charge the first battery 3, thereby maintaining the first battery 3 with sufficient electrical energy to power the electrical components electrically connected thereto. When the solar cell panel 19 cannot generate electricity and needs to supplement electric energy for the first battery 3 in continuous overcast and rainy weather, the control module controls the electric telescopic rod 16 to shrink so that the baffle 17 moves rightwards in the cavity 15 until the through hole 14 is completely opened, then the first reversible motor 10 drives the second driving wheel 11 to rotate so as to drive the first driving wheel 9 to rotate so that the rotating rod 5 and the take-up pulley 6 rotate, the rotating take-up pulley 6 releases the wound charging wire 7, at the moment, the charging head 8 and the released charging wire 7 can move downwards to the outside of the battery compartment 2 through the through hole 14, then the worker inserts the charging head 8 into an external power supply, and accordingly the first battery 3 and the second battery 4 are charged through the external power supply when the solar cell panel 19 cannot generate electricity.

When the first battery 3 and the second battery 4 are fully charged, the charging head 8 can be pulled out from an external power supply, then a worker sends a signal to the control module again through the handheld terminal, the control module controls the first forward and reverse rotation motor 10 to reversely rotate, so that the sent charging wire 7 is wound on the take-up pulley 6 again until the charging head 8 moves into the battery compartment 2 again through the through hole 14, then the electric telescopic rod 16 extends, so that the baffle 17 moves left in the cavity 15 until the left end of the baffle 17 is inserted into the jack 18, at the moment, the baffle 17 completely seals the through hole 14, and rain and snow or other foreign matters are prevented from entering the battery compartment 2 through the through hole 14 to damage parts in the battery compartment 2.

In the application, the electric telescopic rod 16 and the first forward and backward motor 10 are independently powered by the second battery 4, and the electric telescopic rod 16 and the first forward and backward motor 10 do not work in normal sunny weather, so that the second battery 4 hardly consumes electric energy in normal, and the electric telescopic rod 16 and the first forward and backward motor 10 can be powered normally in continuous overcast and rainy weather.

When the parts in the battery compartment 2 are damaged and need to be maintained or replaced, the compartment door 13 can be detached, and the parts in the battery compartment 2 can be maintained or replaced conveniently through the opening on the front side of the battery compartment 2.

In the above-described embodiments, the present utility model provides a cable breakage detection apparatus in which a driving mechanism is capable of moving a cylinder back and forth along a cable, thereby causing a detection mechanism to perform breakage detection back and forth along the cable; in overcast and rainy weather, the charging head and the charging wire can be discharged from the through hole by rotating the wire winding wheel, so that a worker can conveniently plug the charging wire and an external power supply together to charge the first battery; according to the utility model, the wire winding wheel can be reversely rotated in sunny days, and the charging wire is wound until the charging head and the charging wire are stored in the battery compartment, and the through holes are covered by the baffle plate, so that the charging wire and parts in the battery compartment are protected.
