Description

The present invention relates to an extermination apparatus for birds and beasts that exterminates birds and animals such as harmful birds and harmful animals in a predetermined time zone such as nighttime in golf courses, farms, and other fields.

For example, at golf courses, beasts such as spiders and deer are walking around at night, causing damage to dig up grass such as fairways. Similarly, in farms and the like, damages such as digging up fields and eating and destroying crops have occurred.

As a countermeasure, conventionally, land of a predetermined area such as golf courses and farms is surrounded by electric fences, and intrusion of harmful beasts etc. is prevented by a slight current, but electric fences are constructed over a considerable distance, Since a power supply device such as a generator or a battery must be installed, there is a problem that requires high equipment costs and running costs.

In view of this, there has been proposed an apparatus for exterminating birds and beasts by generating an extermination signal such as light and sound waves using a solar cell as a power source.

The extermination device of Patent Document 1 can be installed at any desired location, and has the advantage of facilitating maintenance.

However, since the extermination device simply generates an extermination signal in a state where it is installed and fixed at a desired location, even if it is possible to avoid or exterminate harmful animals during the initial installation, As pests become accustomed to the extermination signal over time, the effectiveness of extermination is greatly reduced.

In addition, the extermination device of Patent Document 1 has a structure in which a square block of hollow blocks is formed by fixing a number of aluminum plate members to a frame-like frame, and a solar cell panel is attached to the aluminum plate member. This is unsuitable for mass production, and there is a problem incurring high costs. In addition, since the extermination device is used in a state where it is installed on the ground, there is a risk that if a harmful animal or the like travels during a pause that does not emit an extermination signal, it will be buried in the earth and sand. Furthermore, since the top of the hollow block made of a quadrangular pyramid protrudes sharply on the ground, there is a risk of not only exterminating harmful animals but also causing injury, which is not preferable from the viewpoint of animal welfare.

It is an object of the present invention to provide a disinfection device that is as cheap as possible by using a mass-production type disinfection unit. Moreover, by maintaining the disinfection device in a suspended state, the installation conditions are suitably maintained, the device is swung and rotated using natural wind power, and further a disinfection signal is generated while actively rotating.
