[0002] With the rapid development of the wind power industry, the construction and operation scale of wind farms has continued to expand, which has put forward higher requirements for the operation and maintenance of wind power equipment. Among them, the stability of communication optical cables, as key facilities connecting wind turbines and control centers, directly affects the normal operation of wind turbines and the operation and management efficiency of wind farms. However, in actual applications, it is found that since most wind farms are located in the wild and the environment is complex, especially the frequent activities of rodents, communication optical cables are often damaged by rodents. In severe cases, it may even cause wind turbine communication interruption, affecting remote monitoring and data transmission. In addition, in wind farms, since communication optical cables and power transmission lines share steel towers, once the optical cables are bitten by rats and need to be repaired, for safety reasons, the power transmission lines often need to be shut down at the same time, which not only causes the loss of electricity, but also increases maintenance costs and human resource consumption.

[0033] See also Figure 3 and Figure 4As shown, the fixing mechanism includes a clamping block 501, a tie I 502 and a tie II 503; the rear side of the left semicircular block I3 is connected to the clamping block 501; two tie ties I 502 are connected to the clamping block 501, and the rear side of the right semicircular block I3 is connected to the tie II 503, and both the tie I 502 and the tie II 503 are used to bind the semicircular block I3 to the steel tower 101 to fix it.

[0034] See also Figure 7-10 As shown, the power-on mechanism includes an arc-shaped conductive plate 1001, a contact head 1002 and a conductive rod 1003; the semicircular block Ⅰ3 and the semicircular block Ⅱ4 on the left are both provided with an arc-shaped conductive plate 1001, and the arc-shaped conductive plates 1001 in the semicircular block Ⅰ3 and the semicircular block Ⅱ4 are in contact with each other, and the left end of the steel wire 8 is connected to the arc-shaped conductive plate 1001; the arc-shaped conductive plate 1001 in the semicircular block Ⅰ3 is connected to the contact head 1002; a conductive rod 1003 is provided in the slider 11, one end of the conductive rod 1003 is connected to the distribution cabinet 12, and the other end is detachably connected to the contact head 1002.

[0035] When in use, first find the communication optical cable 103 fixed on the steel tower 101 by the metal wire fixing ring 102, then rotate and unfold the semicircular block II4 and the semicircular block I3, so that the semicircular block II4 and the semicircular block I3 drive the plastic tube 2 to deform, thereby expanding the pipe seam 201 on the plastic tube 2, and then put the plastic tube 2 on the communication optical cable 103, and then reverse and retract the semicircular block II4 and the semicircular block I3, so that the semicircular block II4 and the semicircular block I3 drive the plastic tube 2 to deform and reset, thereby restoring the pipe seam 201 on the plastic tube 2 to its original state, and then tie the tie ties I502 and II503 to the corresponding steel tower 101, so as to fix the semicircular block I3 (such as Figure 4 As shown), in this way, the communication optical cable 103 can be protected by the plastic tube 2, and then the slider 11 is slid downward and plugged into the clamping block 501, so that the conductive rod 1003 is docked with the contact head 1002, and the power distribution cabinet 12 is connected to an external power supply;

[0036] When the mouse bites through the surface of the plastic tube 2 and pulls the steel wire 8 to move, the left end of the steel wire 8 will drive the arc-shaped rubber plate 7 to deform, so that the arc-shaped rubber plate 7 squeezes the pressure sensor 6. When the pressure sensor 6 senses that the pressure is greater than the preset value, the pressure sensor 6 will send a signal through the signal transmitter 9. After the controller 13 receives the signal, it will control the distribution cabinet 12 to transmit the current to the steel wire 8 through the conductive rod 1003, the contact head 1002 and the arc-shaped conductive plate 1001, so that the steel wire 8 is energized, so that the steel wire 8 electrocutes the mouse, thereby driving the mouse away. When the mouse releases the steel wire 8, the arc-shaped rubber plate 7 returns to its original state, the arc-shaped rubber plate 7 drives the steel wire 8 to move and reset, and the arc-shaped rubber plate 7 gradually stops squeezing the pressure sensor 6. When the pressure sensor 6 senses that the pressure is less than the preset value, the pressure sensor 6 sends a signal through the signal transmitter 9. After the controller 13 receives the signal, it controls the distribution cabinet 12 to stop transmitting the current to the steel wire 8 through the conductive rod 1003, the contact head 1002 and the arc-shaped conductive plate 1001, so that the steel wire 8 is powered off. In this way, it can prevent mice from biting through the surface of the plastic tube 2 and damaging the communication optical cable 103 inside it.

[0037] See also Fig.11 As shown, an insulating shell 14 is also included; the insulating shell 14 is arranged on the slider 11, and the conductive rod 1003 is located on the inner side of the insulating shell 14, and the insulating shell 14 is used to protect the conductive rod 1003, so as to prevent the conductive rod 1003 from being damaged by mice.

[0038] See also Figure 3 and Fig.12 As shown, it also includes a limiting mechanism, which includes a card bead 15 and a spring 16; two card beads 15 are slidably arranged on the front side of the slider 11; a spring 16 is arranged between the front side of the card bead 15 and the slider 11; two card slots 17 adapted to the card beads 15 are opened on the front side of the clamping block 501, and the spring 16 clamps the card bead 15 into the card slot 17 when it is in a normal state.

[0039] When the slider 11 is slid downward and inserted into the snap-in block 501, the slider 11 will drive the card bead 15 downward to approach the snap-in block 501. When the card bead 15 contacts the snap-in block 501, the snap-in block 501 will squeeze the card bead 15 to move forward, and the spring 16 is compressed. When the card bead 15 is aligned with the card slot 17 on the snap-in block 501, the spring 16 returns to its original state, and the spring 16 drives the card bead 15 to move backward and reset, so that the card bead 15 is snapped into the card slot 17. In this way, the card bead 15 can be used to limit the slider 11, so as to stabilize the slider 11 on the snap-in block 501.

[0040] See also Figure 5 and Figure 6As shown, a bolt 18 is also included; a bolt 18 is threadedly connected between the lower side of the semicircular block II4 and the lower side of the semicircular block I3 at the same end of the plastic pipe 2, and the bolt 18 is used to fix the semicircular block I3 and the semicircular block II4.

[0041] When it is necessary to rotate and unfold the semicircular block II4 and the semicircular block I3, first unscrew the bolt 18 from the semicircular block I3 and the semicircular block II4, and then the semicircular block II4 and the semicircular block I3 can be rotated and unfolded; after that, the semicircular block II4 and the semicircular block I3 are reversed and retracted, the bolt 18 can be twisted back to its original position, so that the bolt 18 fixes the semicircular block I3 and the semicircular block II4 to prevent the semicircular block I3 and the semicircular block II4 from being unfolded by being pulled by animals.

When installing the next section of the communication optical cable 103, the docking plate 19 of the previous rodent-proof protection device can be inserted into the docking groove 20 of the next rodent-proof protection device, so that the semicircular blocks I3 and the semicircular blocks II4 of the two rodent-proof protection devices are attached together, thereby docking the two rodent-proof protection devices to prevent a large gap between the two rodent-proof protection devices, thereby preventing mice from damaging the communication optical cable 103 through the gap between the two rodent-proof protection devices; thereafter, when the bolt 18 of the next rodent-proof protection device is twisted back to its original position, the bolt 18 passes through the through hole 1901 of the docking plate 19 of the previous rodent-proof protection device, and the bolt 18 can be used to limit the docking plate 19, thereby fixing the two rodent-proof protection devices, thereby preventing the two docked rodent-proof protection devices from detaching.
