[0039] The above detector (60) is connected and fixed to the inner surface of the detection guide tube member (50) which is connected to the connecting support member (40).

[0040] The above detector (60) is a leakage detector (60) that detects leakage current generated in the object (100), and is fixed by being attached to or screw-fastened to the inner upper surface of the detection guide tube member (50), and detects leakage current generated in the object (100) and transmits a detection signal to the central control unit (70).

[0041] The above central control unit (70) is connected to and fixed to the detection guide member (50).

[0042] The central control unit (70) is fixed by being screw-fastened or attached to the inner or outer surface of the detection guide member (50), and receives a detection signal transmitted from the detector (60) and transmits the detection signal to the transmitter (80) to send it out.

[0043] At this time, the central control unit (70) determines that if the leakage amount of the detection signal transmitted from the detector (60) is higher than the set value, it is unstable and transmits the detection signal to the transmitter (80) to be sent out, and if it is lower, it determines that it is safe and does not transmit it.

[0044] The transmitter (80) is connected to and fixed to the detection guide member (50) and receives and transmits the detection signal from the central control unit (70).

[0062] It is preferable to further form a curved support seating groove on the upper surface of the guide support panel member (52) so that a part of the cable is fitted therein, thereby improving the support and fixing force of the cable and preventing it from moving due to external force.

[0063] It is desirable to further attach and fix an elastic contact support panel made of a synthetic resin material having elasticity on its inner surface to the support mounting groove, thereby supporting a part of the cable fitted into the support mounting groove by the elasticity of the elastic contact support panel, cushioning the transmission of impact and preventing the cable from being damaged by friction.

[0064] It is preferable to fix the lower end of the support cushioning coil spring to the inner bottom surface of the above-mentioned detection guide member (50) by screwing it in, and fix the upper end of the support cushioning coil spring to the bottom surface of the above-mentioned guide support panel member (52) by screwing it in, so that the guide support panel member (52) is supported by the elasticity of the support cushioning coil spring, thereby improving the support and fixing force of the guide support panel member (52) and cushioning the shock transmitted from the outside.

As the driving of the lifting / lowering repellent cylinder (92) and the driving repellent motor (94) causes the driving repellent motor (94) to be lifted and transported, the rotating repellent unit (95) rotates, and the bird can be chased by the movement of the driving repellent motor (94) and the rotating repellent unit (95).

[0070] In addition, it prevents the detection guide member (50) and the object (100) from being damaged by a blow from a bird's beak, or from being corroded by excrement.
