Forest fire prewarning device

Abstract

The invention discloses a forest fire prewarning device which comprises an inlaid frame body and a prewarning device cooperatively mounted on the inlaid frame body, wherein an embedding cavity is formed in the top end surface of the inlaid frame body; a first sliding cavity is formed in a position, which is located on the lower side of the embedding cavity, in the inner wall body of the inlaid frame body in a communicating manner; a sliding seat is mounted in the first sliding cavity in a sliding fit manner; lifting driving mechanisms are arranged on the left and right sides of the sliding seat; a first rotating cavity is formed in the inner wall body of the sliding seat; a first rotating rod connected with the front and rear inner walls of the first rotating cavity in a rotating fit manner is arranged in the first rotating cavity in a front-back extending manner; a first bevel gear is fixedly arranged on the outer surface of the first rotating rod in a circumferential direction; a second bevel gear meshed with the first bevel gear is arranged on the inner bottom wall of the first rotating cavity; the bottom end surface of the second bevel gear is connected with a first motor in apower fit manner.

Description

technical field [0001] The invention relates to the technical field of forest fire early warning, in particular to a forest fire early warning device. Background technique [0002] The occurrence of forest fires is usually divided into two aspects. The first is man-made: smoking, picnics, etc., and the second is caused by spontaneous combustion of methane, lightning, material extrusion, high temperature and dry spontaneous combustion. At present, my country's forest fires The overall monitoring methods are relatively backward. In order to reduce or avoid forest fires, fire alarms are usually installed in mountainous areas. The fire alarms currently used usually use commercial power. The project of pulling wires in mountainous areas is relatively large, which requires a lot of manpower and material resources. The installation steps are cumbersome and the monitoring angle range is small. Contents of the invention [0003] The technical problem to be solved by the present inve...
