Problems solved by technology

Some of the existing bird repellent devices are composed of electrical components, which are expensive and difficult to maintain. Some bird repellent devices with mechanical structures are complex in structure, large in size, and inconvenient to install and use; ultrasonic bird repellent devices have limited coverage and are ineffective. Slow, short life; wind bird repelling device, easy to age, severe natural damage, can not play a role in no wind weather; smell bird repelling device, because the gas is volatile, it will evaporate completely after being placed for about 15 days, and lose the bird repelling function; sound repellent Bird device, birds are very easy to produce adaptability, while other bird repellent devices such as bird repellent thorns and reflectors have single functions, and the effect of repelling birds is not ideal

Embodiment 1

[0025] Example 1 (see figure 1 ), a ring-shaped shell made of polyvinyl chloride plastic, with an outer diameter of 15cm and an inner diameter of 12cm, with a service life of up to 5 years. 24 grooves with the same specifications are arranged in the annular housing, and 4 fastening screws are inserted into the cavity of the annular housing. The superparamagnetic crystals used in this embodiment are produced by Xi’an Tongkai Electronic Technology Co., Ltd., and the diameter of the superparamagnetic crystals used is 1.5 μm. It is very good against natural conditions such as wind, sun and rain. The anti-bird distance of on-site power transmission and transformation insulators is 10 meters. Referring to the anti-bird distance and the magnetic size of block-shaped superparamagnetic crystals, 12 block-shaped superparamagnetic crystals need to be used. Based on aesthetic considerations, their arrangement positions are: In the four equal divisions of the circular housing divided by ...

Embodiment 2

[0026] Example 2, a cubic shell made of silicone rubber, 1.5 cm long, 1.0 cm wide, and 0.5 cm high, with a diameter of 3.5 μm and a block-shaped superparamagnetic crystal slightly larger than the shell was embedded in the shell. Arranged in rows at equal distances on both sides of the airport runway, they can drive away birds within a range of 100 meters.

Embodiment 3

[0027] Example 3, a regular hexagonal shell is made of ceramics, with a side length of 10 cm, a height of 5 cm, and a thickness of 0.1 cm. The inner wall of the shell is smooth and a ceramic shell cover is provided. Superparamagnetic crystals cover the inside of the shell, cover it tightly with a ceramic shell, bury it in the field or hide it in the fruit forest, and drive away birds within a range of 5 meters.

Abstract

The invention discloses a bird scarer and relates to the technical field of bird scaring devices, in particular to a magnetic induction bird scarer applicable to a power transmission line. The bird scarer comprises a casing and superparamagnetic crystals. The superparamagnetic crystals are arranged in the casing, magnetic shafts of the superparamagnetic crystals can be changed according to changes of a surrounding magnetic field. In a geomagnetic field, the superparamagnetic crystals can form a magnetic field big enough to attract or repel nearby crystals, certain matrixes are formed among the superparamagnetic crystals, and magnetic signals are transmitted to bird cells through a certain transmission mechanism so that a bird repelling effect is obtained by enabling birds to change foothold points. The bird scarer is simple in structure and manufacture, small in size, convenient and flexible to install and use, good in effect, long in service life, low in price, wide in application range and especially suitable for bird repelling for power transmission line facilities.

Description

technical field [0001] The invention relates to the technical field of bird frightening equipment, in particular to a magnetic induction bird repelling device suitable for transmission lines. Background technique [0002] In recent years, with the vigorous implementation of the country's bird nature protection policy, the forest vegetation has been restored in a large area, and the population and number of birds have continued to increase. Birds often like to perch or even build nests on high-voltage tower poles of power transmission and transformation, peck insulators and excrete feces on power transmission and transformation equipment, causing a sharp decline in the insulation performance of insulators, causing flashover, failure of insulators, and instantaneous short circuit of lines According to statistics, the line faults caused by birds are second only to lightning damage and external force damage, occupying the third place in the total number of line fault trips, whic...
