The application relates to the technical field of circuit breakers, and provides an outdoor protection type pole-mounted circuit breaker which comprises a circuit breaker main body and a mounting frame body, the circuit breaker main body is arranged on the mounting frame body; the circuit breaker main body is provided with a mechanism box, the top wall of the mechanism box is provided with a mounting strip, the mounting strip is provided with a swing frame, one side of the swing frame is hinged to the mounting strip; a swing assembly is arranged between the swing frame and the mechanism box, and the swing assembly is used for driving the swing frame to reciprocating swing, so as to drive away birds. The outdoor protection type pole-mounted circuit breaker can isolate the stay of birds and keep good heat dissipation of the circuit breaker.

This invention discloses the application of benzyl benzoate in the preparation of repellents for red imported fire ants. Experiments verified that after treatment with benzyl benzoate at a concentration of 1 μL / mL or higher for 0.5 h, the feeding and repellency rate of red imported fire ant workers reached 92.74%. After 12 h of treatment, benzyl benzoate at a concentration of 10 μL / mL or higher still maintained a good repellent effect, indicating that benzyl benzoate has a long-lasting repellent activity against red imported fire ants. After treatment with benzyl benzoate at a concentration of 50 μL / mL or higher for 24 h, the burrowing behavior of red imported fire ant workers was significantly reduced. Benzyl benzoate at a concentration of 10 μL / mL or higher showed good repellent effects against red imported fire ants and can be used in future red imported fire ant protective agents; benzyl benzoate at a concentration of 50 μL / mL or higher can be used in red imported fire ant soil repellents.

This invention relates to the field of snake-proofing technology, specifically a snake-proofing device for power transmission towers. It includes a power pole, a support body fixedly installed on the outer wall of the pole, and a dispersing assembly. The dispersing assembly is installed on the outer wall of the support body, and a driving assembly is located below the dispersing assembly. The dispersing assembly includes a first rotating ring, a second rotating ring, a track ring, and a driving component. The track ring is fixedly installed on the outer wall of the support body. This invention, through the installation of the dispersing and driving components, can repeatedly push snakes off the power pole. In conjunction with the track ring, the dispersing sleeve and dispersing rod can rotate to push the snake off, increasing the driving effect. During the driving process, the second rotating ring collides with a vibrating block, generating strong vibrations. Since snakes are sensitive to vibrations, the strong vibrations frighten them, causing them to escape, thus preventing snakes from climbing the power pole, ensuring the safety of the power grid, and avoiding large-scale power outages.

The application discloses a kind of area grazing device of demarcation wheel area, including mobile part, control module, data acquisition device, sound simulation module and battery module, wherein, control module data acquisition device, sound simulation module and battery module are all set on the mobile part, the mobile part is moved along the preset route by control module control, data acquisition device the control module remains connection, to collect the real-time data of field of pasture, sound simulation module is connected with control module, and the sound played through the sound simulation module can make the sensitive response of herd, to drive herd, battery module provides power for the data acquisition device, control module and sound simulation module described above.The present application monitors herd in real time through image acquisition probe, at the same time, NDVI probe monitors the pasture height of pasture demarcation, so as to drive herd to the next pasture round area when the pasture height reaches the minimum preset height, and then realize unmanned grazing, reduce workload, reduce grazing cost.
