Bird repellent device

Abstract

A bird-repelling device includes a panel and a movable eyelid. The panel has an eye pattern, an arc-shaped through hole above the eye pattern, two shaft sleeves are connected to the inner wall of the arc-shaped through hole, and a metal sheet is arranged above the arc-shaped through hole. The movable eyelid includes a spherical thin sheet, four elastic limiting columns, a wind sheet, and two rotating shafts. The rotating shaft is inserted into the shaft sleeve. When there is wind, the wind blows on the wind sheet, and the movable eyelid shakes with the wind, and the eye pattern has a dynamic effect of opening and blinking. At the same time, the elastic limiting column hits the metal sheet to make a sound, thereby driving away the birds. The movable eyelid is shaken by using natural wind energy and the elastic potential energy of the elastic limiting column, and the elastic limiting column hits the metal sheet to make a sound. No additional energy is required for driving, and no personnel maintenance is required, which saves costs and resources. The movable eyelid has strong versatility and is easy to install. The movable eyelid also has the function of shielding the eye pattern from wind, rain and sunlight, so that the eye pattern maintains its color for a long time.

DETAILED DESCRIPTION

[0024] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0025] See also Figure 1-7 A bird-repelling device comprises a panel 1 and a movable eyelid 2. The panel is provided with an eye pattern 11. The eye pattern 11 can be provided on the front side (the present embodiment only takes the front side as an example) or on both sides. An arc-shaped through hole 12 is provided above the eye pattern 11. Two shaft sleeves 13 are symmetrically fixedly connected to the inner walls on both sides of the arc-shaped through hole 12. A metal sheet 14 is fixedly connected above the arc-shaped through hole 12. The metal sheet 14 can be made of brass.

[0026] See also Figure 1-3 and Figure 5-7 The movable eyelid 2 includes a spherical sheet 21, an elastic limiting column 22, a wind sheet 23, and a rotating shaft 24;

[0027] The spherical sheet 21 has a curvature that matches the curvature of the arc-shaped through hole 12, and a length that is shorter than the length of the arc-shaped through hole 12, thereby ensuring that the spherical sheet 21 and the arc-shaped through hole 12 are gap-matched.

[0028] There are four elastic limiting columns 22, which are symmetrically fixed at the front and rear edges of the top surface of the spherical sheet 21. The elastic limiting columns 22 can be made of highly elastic plastic material, and the upper end is made into a spherical shape to reduce the contact area between the elastic limiting columns 22 and the metal sheet 14 when knocking the metal sheet 14, so that the knocking sound is as loud as possible;

[0029] The wind blade 23 is fixedly arranged at the center between the front and rear edges of the top surface of the spherical thin sheet 21. After the movable eyelid 2 is mounted on the panel 1, the height of the wind blade 23 is lower than the height of the arc-shaped through hole 12, ensuring that the wind blade 23 and the arc-shaped through hole 12 are in clearance fit.

[0030] The rotating shafts 24 are two in number and are fixedly connected to the left and right sides of the top surface of the spherical sheet 21 , and are rotatably connected to the shaft sleeve 13 in a corresponding position and with clearance fit.

[0031] See also Figure 6 and Figure 7 Furthermore, the four elastic limiting columns 22 are of equal height, and after the movable eyelid 2 is installed on the panel 1, the height of the elastic limiting columns 22 reaches the middle of the side of the metal sheet 14. After the movable eyelid 2 is installed on the panel 1, the height of the four elastic limiting columns 22 is higher than the arc-shaped through hole 12 and lower than the metal sheet 14, ensuring that the spherical sheet 21 within the range of the front and rear edges of the top surface of the spherical sheet 21 sways with the wind in the arc-shaped through hole 12, and at the same time ensuring that the elastic limiting columns 22 hit the middle of the side of the metal sheet 14.

[0032] See also Figure 1 , Figure 4 , Figure 6 and Figure 7 Furthermore, the panel 1 is provided with a mounting through hole 15 near the lower edge, and the mounting through hole 15 is provided to prepare for on-site installation.

[0033] The bird repellent device is used as follows:

[0034] The two rotating shafts 24 of the movable eyelid 2 are respectively inserted into the two shaft sleeves 13 of the panel 1 (lubricating oil can be added), the metal sheet 14 is fixedly connected to the top of the arc-shaped through hole 12, and the bird-repelling device is installed at the site where birds need to be repelled.

[0035] When there is wind, the wind blows on the wind sheet, the movable eyelid 2 swings with the wind, and the eye pattern 11 has a dynamic effect of opening and blinking. At the same time, the elastic limiting column 22 hits the metal sheet 14, making a sound to drive away the birds.
