In the eighth invention, it provided the controller 20 for a predetermined time driving control such as when the moving means and intimidating means e.g. sunset.

  Since the present invention threatens while moving, it is difficult for birds to get used to the mechanism of threats, and it will continue to exert repellent effect reliably, can effectively prevent bird damage over a long period of time, and within a certain range of steel towers Because it moves up and down, it is not necessary to provide many, unlike nets and ropes, it can be provided at low cost, the mounting position is clear, it does not hinder the maintenance and inspection work of power transmission equipment and equipment, and installation work is also easy It is. In particular, if a striking device is provided, the vibration is transmitted to the entire power transmission tower along with the striking sound, and the birds can be driven away more reliably. The escort rail of the existing power transmission tower can be used as a guide member for the lifting body, which simplifies the configuration of the apparatus and is more economical. If a solar cell module is used as the driving power source, the necessary power source power can be maintained for a long time without being charged. If the operating time is limitedly used in accordance with the habits of birds, consumption of members and energy can be reduced and long-term use becomes possible.

An embodiment of the present invention will be described with reference to the drawings.
In FIG. 1, the bird damage prevention apparatus according to the present invention includes a guide rail 1 and an elevator 2 that constitute a moving means. The guide rail 1 can also serve as a predetermined range including the height of the escort rail transmission line retaining height for movably connecting a safety belt for preventing the fall of the worker laid in the vertical direction in the power transmission tower T. The guide rail 1 is made of a long plate-like material having a substantially C-shaped cross section, and a running surface 1b is formed on both side edges forming the split 1a, and the upper and lower rollers 4 and 5 of the elevator 2 are rolled thereon. Thus, the elevator 2 can move the power transmission tower T in the vertical direction along this.

  As shown in FIGS. 2 to 5, the elevator 2 includes a carriage 3 having rollers 4 and 5 above and below a substantially rectangular base plate 3 a that is vertically long. Along with these, both rollers 4 and 5 are respectively provided with presser rollers 6 facing the running surface 1b of the guide rail 1 in the front-rear direction. The presser roller 6 is rotatably supported by a bearing 8 that protrudes toward the guide rail 1 through a support rod 7 supported by the carriage 3. The support rod 7 passes through the split 1 a and extends into the guide rail 1. A guide roller 9 positioned in the split 1a is rotatably supported on the support rod 7. Since the support rod 7 on the lower roller 5 side is supported by the carriage 3 via the spring 10, the lower roller 5 and the presser roller 6 elastically sandwich the running surface 1 b of the guide rail 1. The lower roller 5 is fixed to a drive shaft 13 that is coupled via a speed reducer 12 to a shaft of a drive motor 11 that protrudes laterally from the carriage 3.

  On the carriage 3, a striking device 14 which is one of threatening means is provided. As shown in FIGS. 3, 6, and 7, the striking device 14 includes a transmission mechanism 15 that transmits power from the drive shaft 13 and a striking mechanism 16 that strikes the guide rail 1. The transmission mechanism 15 is connected to the drive shaft 13 via a one-way clutch and rotates together in one direction, a driven shaft 15d that is rotatably supported at a substantially middle portion of the base plate 3a of the carriage 3, A driven gear 15c fixed on the driven shaft 15d and rotating together, and a chain 15b wound around the gears 15a and 15d. The striking mechanism 16 includes a cam 16a fixed on the driven shaft 15d and rotating together, a striking pin 16b disposed in the vicinity so as to face the cam 16a, and a cylindrical guide cover for guiding the movement of the striking pin 16b. 16c and a spring 16d for holding the striking pin 16b in a predetermined position inside the guide cover 16c. The striking pin 16b is guided in movement in the axial direction because the engaging portion protruding in the lateral direction passes through the split of the guide cover 16c. Further, a spring receiver is fixed to one end of the striking pin 16b, and two springs 16d and 16d are locked between the front and rear of the spring receiver and the end wall of the guide cover 16c and an intermediate partition. Therefore, after the cam 16a is engaged with the striking pin 16b, when the striking pin 16b is returned to the original position when it is separated from the striking pin 16b by pushing up the striking pin 16b while compressing one of the springs 16d and extending the other. The guide rail 1 is beaten beyond the original position due to inertia.

  On the carriage 3, an in-vehicle box 17 in which a light emitting body 18 that is one of threatening means is arranged on both sides. On the in-vehicle box 17, a solar panel 19 is mounted that is tilted upward and fixed while the elevator 2 is mounted on the guide rail 1. The solar panel 19 constitutes a power supply means that is a solar cell module that is charged by solar energy in the daytime, and drives the elevator 2 up and down with the charging power and turns on the light emitter 18. The luminous body 18 emits strobe light at 60 to 100 times per minute every 15 minutes at sunset when birds frequently fly in groups. The controller 20 that controls the operation is accommodated in the in-vehicle box 17. Limit switches 21 for restricting the vertical movement range on the guide rail 1 are attached to both the front and rear and upper and lower ends of the carriage 3, and the stop position is detected and the controller 20 performs stop reverse running control.

  In this bird damage prevention apparatus, an elevator 2 is mounted on a guide rail 1 serving as an escort rail that is fixed in the vertical direction along the transmission tower T. The elevator 2 is mounted from the lower end of the guide rail 1 by placing the presser roller 6 in the guide rail 1 so that the running surface 1b is sandwiched between the upper and lower rollers 4 and 5 and the presser roller 6 from the lower end of the guide rail 1. . In this state, the pressing roller 6 elastically holds the traveling surface 1b between the upper and lower rollers 4 and 5 by the spring 10, so that the elevator 2 is securely attached to the guide rail 1 without dropping off. And the elevator 2 reciprocates up and down on the guide rail 1 every 15 minutes about 2 hours at sunset. The elevator 2 moves smoothly along the guide rail 1 because the guide roller 9 moves in the split 1 a of the guide rail 1.

  When the elevator 2 moves, the striking mechanism 16 in the striking device 14 operates via the transmission mechanism 15, and by striking the guide rail 1, the striking sound and vibration transmitted to the steel tower are effectively threatened to transmit power. Drive away from the tower T. In the striking device 14, when the elevator 2 moves downward, the one-way clutch on the drive shaft 13 is coupled and the gear 15a rotates together, and the cam 16a rotates through the chain 15b, the driven gear 15c, and the driven shaft 15d. . After the cam 16a abuts against the striking pin 16b of the striking mechanism 16 with which the cam 16a engages and the cam 16a compresses the spring 16c and pushes up, the cam 16a is detached and the striking pin 16b returns to its original position. Tap. Since the elevator 2 moves and the threatening means changes its position, it is difficult for birds to get used to the operation of the threatening means.

  The light emitter 14 on the elevator 2 repeatedly emits strobe light at a blinking frequency of 60 to 100 times per minute while moving. The blinking accompanied by the movement of the luminous body 14 effectively threatens the birds flying to the power transmission tower T and drives them away from the power transmission tower T. Since the elevator panel 2 automatically charges the driving power required for operation by the solar energy during the daytime, no replenishment operation is required. Further, since the operation is controlled by the controller 16, it can be completely unmanned.

In addition, when the escort rail is bent in the lateral direction while being extended, only the necessary portion of the upper portion where birds are likely to stay may be reciprocated.
In addition, the moving means is configured such that the elevator 2 can move along the guide rail 1. However, pulleys are provided at upper and lower positions within a predetermined range of the tower, and wire ropes are hung around these pulleys. The threatening means may be reciprocated up and down by locking the means and drawing the wire rope.

  Further, the striking pin 16b in the striking device 14 operates only when the elevator 2 is moved downward by the one-way clutch on the drive shaft 13. However, the striking pin 16b is hit by connecting the one-way clutch when moving upward by a known means. The pin 16b may be actuated, or the striking pin 16b may be actuated in both forward and reverse rotation directions by omitting the one-way clutch.

  The present invention is effective for driving away birds from a power transmission tower and preventing bird damage such as a ground fault.
