detailed description

The present invention will be described in detail below in conjunction with the accompanying drawings.

As shown in Figure 1, the present invention discloses a tipping bucket bird repelling device, which is used to be installed on the cross arm of the electric pole. The tipping bucket bird repelling device includes a shielding part 1, which has The detachable connection of the first connecting seat 3, the strut 4 arranged on the first connecting seat 3 and the bird-repelling baffle 5 used to cover the cross arm, the bird-repelling baffle 5 is arranged on the strut 4 through the rotation of the rotating part one end.

As shown in Figures 2-7, specifically, the bird repelling baffle 5 includes a first plate 9 and a second plate 10, and there is an included angle between the first plate 9 and the second plate 10 (this embodiment In the example, this included angle is 120 °, certainly also can be other degrees) so that when the bird repelling baffle 5 is in the natural state, the plate surfaces of the first plate 9 and the second plate 10 can be surrounded by the plane where the cross arm is located. into a triangle. The rotating part includes a connecting shaft 8 arranged at one end of the strut 4 and connected with the strut 4 to form a T-shape, a bearing 39 and a rotating joint 11 . Both ends of the connecting shaft 8 have a first stepped portion 40, a second stepped portion 41 and a third stepped portion 42 whose outer diameter gradually increases from the end of the connecting shaft 8, and the first stepped portion 40 is threadedly connected with a stop nut 44. The bearing 39 is sleeved on the second stepped portion 41. In this embodiment, the inner ring of the bearing 39 is fixedly connected with the second stepped portion 41, and the outer ring of the bearing 39 can rotate relative to the inner ring. Wherein, the diameter of the inner ring of the bearing 39 is smaller than the outer diameter of the third stepped portion 42, so that the bearing 39 can be limited between the limit nut 44 and the third stepped portion 42, that is, to further ensure that the bearing 39 is limited to the second stepped portion 42. on the step portion 41 to prevent it from slipping off. In addition, the axial direction of the connecting shaft 8 is parallel to the length direction of the cross arm, and the first plate 9 and the second plate 10 are symmetrical about the axis of the connecting shaft 8, so that the bird repelling baffle 5 can stably surround the connecting shaft 8 turn. The rotary joint 11 in the present embodiment is cylindrical, and it is arranged on one end of the bird-repelling baffle 5 and coaxially arranged with the connecting shaft 8 (the first plate 9 and the second plate 10 rotate the joint 11 relatively at the same time. 3 and 6, the rotary joint 11 has a stepped hole in the axial direction for being socketed with the bearing 39 and correspondingly surrounding the first stepped portion 40 and the second stepped portion 40 after being socketed with the bearing 39. The stepped part 41 , that is, the rotating joint 11 is provided on the connecting shaft 8 through being socketed and rotating with the bearing 39 . Since the axis of the rotating joint 11 is collinear with the axis of the connecting shaft 8, the position of the relative connecting shaft 8 is fixed when the two plates are installed on the connecting shaft 8 without external force, and once a bird falls on any After one board is installed, the force of the two boards changes, so under the action of the external force, the relative connecting shaft 8 rotates, and then the birds are dispersed without harming the birds; and when the birds leave the bird-repelling baffle 5 Finally, the bird-repelling baffle 5 continues to return to a stable initial state under the effect of its own gravity. Preferably, in order to prevent impurities such as sand from entering the bearing 39, the second stepped portion 41 is also sleeved with a shaft end baffle 38 that is connected to the bearing 39 (the shaft end baffle 38 is located at the bearing 39 near the third stepped portion 42), the outer edge of the shaft end baffle 38 is provided with an adhesive layer (specifically, it can be formed by coating the outer ring of the shaft end baffle 38 with adhesive). The shaft end baffle 38 in this embodiment is shown in Figure 13, and its adhesive layer is arranged on the outer edge of the circle with the largest outer diameter of the shaft end baffle 38, and the protruding part in the middle of the shaft end baffle 38 extends into the corresponding In the inner ring of the bearing 39, when the rotating joint 11 is socketed with the bearing 39, the outer edge of the shaft end baffle 38 is connected with the hole wall of the stepped hole of the rotating joint 11 through the adhesive layer, so that the rotating joint 11 11 is more firmly connected with the bearing 39.

Preferably, continuing to refer to FIG. 7 , in order to restore the balance of the bird-repelling baffle 5 faster after being stressed, the shielding part 1 in this embodiment also includes a balance plate 12, which is arranged on the bird-repelling baffle. When the plate 5 is in a natural state, the side away from the cross arm and the included angle between the first plate 9 and the second plate 10 are equal to 120°. The sides of the first plate 9, the second plate 10 and the balance plate 12 are jagged to prevent birds from landing on the sides of each plate, forcing the birds to land on the first plate 9 or the board surface of the second board 10, thereby achieving the effect of repelling birds. In order to reduce the rotational resistance of the bird-repelling baffle 5 , the thickness of each plate in this embodiment gradually decreases from the connection with the rotating joint 11 to the direction away from it. In addition, the length of the balance plate 12 (the length in the length direction of the connecting shaft 8) is the same as the length of the first plate 9 and the second plate 10, but the width can be smaller than the first plate 9 and the second plate The width of 10 is enough to ensure that it can play a balancing role.

Further, as shown in Figures 4 and 5, the first connecting seat 3 is U-shaped, and the first connecting seat 3 has a first U-shaped opening 13 for enabling it to be placed laterally outside the cross arm. The bottom surface of the seat 3 is pierced with tightening bolts 14 for tightening the cross arm, and the strut 4 is connected with the top surface 15 of the first connecting seat 3 .
