Spontaneous combustion prevention garbage can for green city

Abstract

The invention discloses a spontaneous combustion prevention garbage can for a green city. The spontaneous combustion prevention garbage can comprises a can body, wherein a groove is formed in the bottom in the can body, a sliding plate is slidably connected to the inner wall of the groove in a sealed mode, electromagnetic plates are embedded in the lower end of the sliding plate, and permanent magnet plates repelling the electromagnetic plates are embedded in the bottom in the groove; and a first power supply mechanism for supplying power to the electromagnetic plates according to the temperature change in the can body is mounted on the sliding plate, a strip-shaped cavity is formed in the side wall of the can body, a sliding plug is slidably connected to the inner wall of the strip-shaped cavity in a sealed mode, and a partition plate is fixedly connected to the upper end of the sliding plug. A memory spring contracts to drive a current-conducting plate to slide, so that the current-conducting plate is separated from a current-conducting block, then magnetism on the electromagnetic plates disappears, the sliding plate descends under the gravity effect of garbage in the can body, gas in the groove is extruded into the strip-shaped cavity through a connecting pipe, the sliding plug slides upwards to drive the partition plate to slide, the upper end of the can body is sealed to isolate air, the oxygen content in the can body is reduced, and the fire extinguishing effect is achieved.

Description

technical field [0001] The invention relates to the technical field of green cities, in particular to an anti-spontaneous combustion garbage bin for green cities. Background technique [0002] Green city was put forward in the "green movement" to protect the global environment. It refers to urban construction that not only emphasizes ecological balance, protection of nature, but also pays attention to human health and cultural development. When building a green city, in order to avoid urban garbage If there is flooding, multiple trash cans will be set up. [0003] But at present, when people are throwing garbage, they often throw unextinguished cigarette butts or combustibles into the garbage can, so that when the garbage can is relatively dry, it is easy to cause the garbage in the garbage can to burn, and the current garbage The function of the bucket is single, and the fire in the garbage can cannot be extinguished in time, so that the fire in the garbage can increases, ...

AI Technical Summary

Problems solved by technology

[0003] But at present, when people are throwing garbage, they often throw unextinguished cigarette butts or combustibles into the garbage can, so that when the garbage can is relatively dry, it is easy to cause the garbage in the garbage can to burn, and the current garbage The function of the bucket is single, and the fire in the garbage can cannot be extinguished in time, which makes the fire in the garbage can increase, which is easy to cause a fire.
