Embodiment Construction

[0014] A snow alarm and automatic salt spreading device of the present invention is mainly composed of a snow collecting device and an automatic salt spreading device, wherein the snow collecting device is as figure 2 with image 3 As shown, the infrared alarm (1) is installed on the inner wall of the snow box (2) at a certain height, and the height is the limit of the allowable snow thickness set. Such as figure 1 As shown, the salt storage rotating part (4) of the automatic salt spreading device is composed of inner and outer layers, wherein barbs (3) are welded on the inner wall of the outer layer. The inner layer is a semicircular concave that stores a certain amount of salt. Between the inner and outer layers is a grid channel (5). The inner and outer layers are in accordance with figure 1 Shown welded to the steel plate below. Below the channel is a component composed of two flat plates that can directly spray salt particles. A cylinder is welded in the center of t...

Abstract

The invention discloses a snows alarming and automatic salt spreading device. The device consists of a snows collecting device and an automatic salt spreading device which are separately arranged, the snows collecting device is composed of an infrared alarm and a snows box, and the automatic salt spreading device comprises a salt storing and rotating part, a servo motor, a servo motor controller and a fixed box; the snows alarm at certain thickness can be realized by the snows collecting device, the automatic salt spreading device can automatically start the salt spreading device after an alarm signal is received so as to realize an effect of spreading a salt spreading block snow-melting agent, therefore the hazard of crushing the roof by heavy snow can be effectively prevented; furthermore, the snows alarming and automatic salt spreading device can alert people at the night with sudden snowfall, and provide a guarantee for the safety of people.

Description

technical field [0001] The invention relates to a snow accumulation alarm and automatic salt spreading device, which belongs to the field of mechanical design. Background technique [0002] Snow disaster, also known as white disaster, is a natural phenomenon caused by large-scale snow accumulation caused by long-term heavy snowfall. When a snow disaster occurred in China in 2008, large-scale rain and snow occurred for three consecutive days from January 19 to 21 from west to east. Among them, in Hubei and Anhui, more than 8 million people were affected, more than 50,000 people were evacuated urgently, and nearly 10,000 Houses collapsed and economic losses amounted to 1.1 billion yuan. [0003] Snow melting agent is mainly used for snow removal in winter and road anti-freezing. Currently, there are two types of snow melting agent. One is organic snow melting agent with potassium acetate as the main component. This kind of snow melting agent has good snow melting effect and ...
