A combined anti-bird device

Abstract

The invention discloses a combined bird expelling device which comprises a bird net and vertical columns, wherein two sides of the bird net are arranged on the vertical columns on two sides. The combined bird expelling device is characterized in that the lower ends of the vertical columns are fixed on bases; a linking rod is arranged between two adjacent bases; two side edges of the bird net between the two vertical columns slide up and down synchronously on the vertical columns. The combined bird expelling device is applicable to airports, is easy to mount and dismount, free of gap, and relatively convenient to use, and flying birds can be effectively prevented from flying into airfield runways.

Description

technical field [0001] The invention relates to the improvement of an airport bird-proof device, in particular to a combined bird-proof device. Background technique [0002] Birds at the airport pose a serious threat to aircraft takeoff and landing. How to reduce the number of birds at the airport and prevent birds from entering the runway area is a major challenge for airport staff. At present, the commonly used bird repelling methods in airports include sound and light methods, chemical methods, artificial repelling methods, etc. These methods cannot completely prevent some birds from suddenly breaking into the airstrip. A barrier is crucial. The commonly used anti-bird nets are mainly composed of ordinary bird nets and bamboo poles, and the ordinary bird nets are tied to the bamboo poles by ropes; the disadvantage is that due to the existence of mesh deformation, there will be more Gaps, so lingering birds such as sparrows will enter the airstrip through these gaps afte...

At present, the commonly used bird repelling methods in airports include sound and light methods, chemical methods, artificial repelling methods, etc. These methods cannot completely prevent some birds from suddenly breaking into the airstrip. A barrier is crucial

The commonly used anti-bird nets are mainly composed of ordinary bird nets and bamboo poles, and the ordinary bird nets are tied to the bamboo poles by ropes; the disadvantage is that due to the existence of mesh deformation, there will be more Gaps, so lingering birds such as sparrows will enter the airstrip through these gaps after they are familiar with the bird nets; at the same time, climbing equipment is required for hanging, and the installation is complicated, and the replacement of bird nets is complicated. The height of the climbing equipment determines the height of the bird net suspension. Generally, the hanging height of the bird net is relatively low; it is inconvenient in the process of taking out the bird caught in the net, and it is necessary to use auxiliary equipment to remove the bird from a high place
