Abstract

Disclosed are a bird expelling method and a waistcoat using ultraviolet reflection of titanium dioxide. On the basis of the fact that birds are sensitive to some bands of ultraviolet, titanium dioxide particles with the wavelength same as the bands sensitive to birds are selected and applied to a waistcoat ordinarily worn by a bird expelling worker. The bird expelling waistcoat comprises a cloth layer (1) and a titanium dioxide particle layer (2) adhered to the cloth layer (1) by a Velcro, and the ultraviolet reflection wavelength of the titanium dioxide particles is between 350 nm and 360 nm, between 360 nm to 370 nm, and between 370 nm to 380 nm. Most of birds are especially sensitive to these bands of ultraviolet. When seeing ultraviolet reflected waves of the titanium dioxide particles, birds can distinguish the bird expelling worker at a longer distance and evade the worker in advance, such that a better bird expelling effect is achieved, and the risk of bird strike is reduced. Furthermore, the labor intensity of the worker can be reduced, and the waistcoat is simple in structure and low in production cost.

Description

Bird repellent method using titanium dioxide ultraviolet reflection and vest

Technical field

The invention relates to a bird-repelling technology, and in particular, to a method and a device for expelling birds through ultraviolet reflection.

Background technique

Bird strike refers to a flight accident caused by a collision between a bird and an airplane. It has multiple occurrences and emergencies. Once it occurs, it will cause damage to the airplane, even cause it to crash, and cause major casualties. Therefore, the airport management department will Set bird repellent personnel and take various measures to reduce bird strike risk.

Experimental research shows that birds are sensitive to ultraviolet rays. The main reasons are: first, many fruits can reflect ultraviolet rays, which can enhance the ability of birds to search for fruits; second, the breeding feathers of many species can reflect ultraviolet rays, which can enhance the opposite sex Selection ability. Therefore, the use of ultraviolet rays can enhance the ability of birds to recognize certain objects.

Different birds have different sensitivities to different wavelengths. For example, carrier pigeons are particularly sensitive to the band around 360nm [Zhang Yun, Research on UV Color Sense of Birds, China Science and Technology Information 2017, No. 20], and sparrows are sensitive to 370nm [Chen Demao, The four-color seductive vision of bird's eye, Science Bulletin, No. 22, 1986]. Therefore, the principle of ultraviolet reflection can be used to repel birds.

Titanium dioxide has a reflective effect on ultraviolet rays. The reflection wavelength is closely related to the particle size. The larger the particle size, the larger the reflection wavelength. Therefore, the ultraviolet reflection function of titanium dioxide can be used to repel birds.

Invention patent content

In view of the above problems, the present invention provides a bird repellent method and vest using titanium dioxide ultraviolet reflection. The bird repellent principle is based on the principle that birds are sensitive to ultraviolet reflection at certain wavelengths, which can achieve better bird repellent effect and lower cost. The labor intensity of bird-repelling personnel can also be reduced.

To achieve the above objectives, the present invention proposes the following technical solutions:

A bird repellent method using titanium dioxide ultraviolet reflection includes the following steps:

Step 1: Determine the species of high-risk birds within the range to be repelled;

Step 2: detecting the sensitive ultraviolet wave band of the high-risk bird;

Step 3: Select a dioxin whose ultraviolet reflection wavelength is the same as that of the ultraviolet band to which the high-risk bird is sensitive.

Titanium particles

Step four: setting the titanium dioxide particles on a vest worn daily by airport staff;

The ultraviolet reflection wavelengths of the titanium dioxide particles are between 350-360 nm, 360-370 nm, and 370-380 nm.

A bird-repellent vest utilizing titanium dioxide ultraviolet reflection includes a cloth layer, a connecting member, and a titanium dioxide particle layer. The titanium dioxide particle layer is provided with a plurality of titanium dioxide particles having different ultraviolet reflection wavelengths, and the ultraviolet reflection wavelengths are respectively corresponding to corresponding high risks. Birds are sensitive to the same ultraviolet wavelength band, the number of the connecting members is equal to the number of the titanium dioxide particle layers, the titanium dioxide particle layers are fixedly connected to the connecting members, and the connecting members are detachably provided on the cloth On the floor

The ultraviolet reflection wavelength of the titanium dioxide particles is in a range of 350 to 360 nm, 360 to 370 nm, and 370 to 380 nm.

The connecting piece is a Velcro.

The connecting member is detachably disposed on the shoulders, the front, the back, and the sides of the vest.

The invention has the following beneficial effects:

The invention utilizes the ultraviolet reflection effect of titanium dioxide and the birds are sensitive to ultraviolet rays in certain bands. The titanium dioxide particles having the same ultraviolet reflection wavelength as the ultraviolet wavelength sensitive to high-risk birds are applied to the vests usually worn by bird-repelling personnel. Birds When you see the ultraviolet rays reflected by the titanium dioxide particles, you can identify the bird repellent from a longer distance, so as to avoid them early, you can achieve a better bird repellent effect, and reduce the risk of bird strike. Titanium dioxide's ultraviolet reflection is stable, so the bird-repelling effect is stable, and it can also reduce the labor intensity of the staff.

As shown in FIG. 1, the bird-repellent vest includes a cloth layer 1 and a titanium dioxide particle layer 2 attached to the cloth layer 1 through a magic tape. The ultraviolet reflection wavelength of the titanium dioxide particles is between 350 to 360 nm, 360 to 370 nm, and 370 to 380 nm. Most birds are particularly sensitive to these bands of ultraviolet light, so the titanium dioxide particle layer can be detachably connected to the cloth layer 1 through a Velcro, which can strengthen the warning effect for birds and make it easier for birds to notice the bird repellent wearing a vest. Personnel, thereby avoiding bird-repelling personnel earlier and further, reducing the risk of bird strikes.
