[0013] The technical solution of the present invention will be further described below with reference to the embodiments and the accompanying drawings.

[0014] Example:

[0015] This embodiment is a multifunctional iron tower, such as Figure 1 As shown, the tower body 1, antenna 2, vertical axis wind turbine 3, floating bird-repelling mechanism 4 and lightning rod 5, the antenna 2 is arranged on the upper part of the tower body 1, the vertical axis wind turbine 3, the floating bird-repelling mechanism 4 and the lightning rod 5 are arranged on the upper end of the tower body in sequence, and when the vertical axis wind turbine 3 rotates, the floating bird-repelling mechanism 4 is driven to float up and down.

[0016] like Figure 2As shown, the floating bird-repelling mechanism includes a cylinder 41, a floating block 44, a support spring 43, a lifting spring 42 and a bird-repelling needle 48. The cylinder 41 is cylindrical and has an opening at the lower end. The opening is provided with a circle of retaining edge. The opening of the cylinder 41 is set downward. A groove is provided on the side of the cylinder 41. The floating block 44 is a circular column. The floating block 44 is slidably set in the cylinder 41. The support spring 43 is set between the lower end of the floating block 44 and the retaining edge. The lifting spring 42 is set between the upper end of the floating block 44 and the bottom surface of the cylinder 41. Support arms 45 are set at both ends of the floating block 44. The support arms 45 extend through the groove to the outside of the cylinder 41. The bird-repelling needle 48 is set at the end of the support arm. The lower end of the floating block 44 is provided with an abutting arm 46. The abutting arm 46 is set through the cylinder retaining edge. The lower end of the abutting arm 46 is provided with a concave-convex portion. The upper end of the rotor of the vertical axis wind turbine is provided with a concave-convex plate 47 matching the concave-convex portion, and the abutting arm abuts against the concave-convex plate. The concave-convex portion can be a first ratchet tooth distributed in an annular pattern, a second ratchet tooth is provided on the concave-convex plate, and the first ratchet tooth matches the second ratchet tooth; the concave-convex portion can also be a hemispherical protrusion and hemispherical groove distributed in an annular pattern and alternately arranged, and the concave-convex plate is provided with a hemispherical protrusion and hemispherical groove matching the concave-convex portion. In this embodiment, the combined force of the support spring and the lifting spring should be equal to or slightly less than the weight of the entire floating block, so that the abutment arm just contacts the concave-convex plate or there is a small pressure between the abutment arm and the concave-convex plate. When the rotor of the vertical axis wind turbine rotates under the action of wind, it drives the concave-convex plate to rotate. The rotation of the concave-convex plate cooperates with the concave-convex portion on the abutment arm, allowing the floating block to float up and down. While using wind power to generate electricity, it drives the bird-repelling needle to float up and down, thereby improving the bird-repelling effect.

[0017] In addition, in order to ensure that the concave-convex portion can cooperate with the concave-convex plate, the abutment arm needs to be set concentrically with the concave-convex plate. Therefore, a groove is provided in the center of the lower end of the abutment arm, and a convex column is provided in the center of the concave-convex plate. The groove matches the convex column, and both the groove and the convex column are cylindrical.

[0018] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope of the appended claims.
