Late spring coldness prevention device heated by electric energy heating

Abstract

A late spring coldness prevention device heated by electric energy heating comprises a steel wire frame device arranged on the upper portion of an orchard and used for fruit tree branch tendril building and electric energy heating, and further comprises a temperature electric control device used for electrifying the steel wire frame device to enable the steel wire frame device to heat, and the steel wire frame device comprises a plurality of steel strands supported on the upper portion of the orchard through a supporting frame. A temperature electric control device comprises a single-chip microcomputer, a leakage protector, a transformer, a current controller and a switch, the leakage protector is connected with an external power supply device and electrically connected with the transformer, the transformer is electrically connected with the single-chip microcomputer, and the current controller is electrically connected with the single-chip microcomputer. And the single chip microcomputer is electrically connected with the head part and the tail part of a communication line formed by stringing a plurality of steel strands through a switch. The point steel strands are electrified and produce heat to increase the temperature near an orchard, the problem of late spring coldness can be fundamentally solved, agricultural production is promoted, and the income of farmers is increased.

Description

technical field [0001] The invention belongs to the technical field of frost prevention in orchards, and in particular relates to a device for preventing late spring cold by heating and heating with electric energy. Background technique [0002] The cold weather in early spring every year will affect the flowering of fruit trees in many areas, such as the kiwi fruit garden in Meixian County, Shaanxi Province. The reason for the coldness in late spring is mostly caused by the cold air. In spring, the transitional period from winter monsoon to summer monsoon, when the cold air from the north still hits from time to time, the cold air goes south and keeps warm and humid air from the south. Will form persistent low temperature, cloudy and rainy weather. The later and stronger the cold air goes south, and the wider the cooling range, the greater the possibility of late spring cold. For example, from the evening of April 6th to the early morning of April 7th, 2018, the rare cold...

AI Technical Summary

Problems solved by technology

The disadvantages of this method are: the coverage area is not uniform, the smoke suspension is related to the size ratio of frost particles, and if the frost damage is serious, the antifreeze effect cannot be achieved.

The disadvantage of this method is that the coverage area is not uniform, and some frost particles will adhere to the surface of the blade during the air flow, resulting in no antifreeze effect

Its disadvantages: it can only delay the flowering period of fruit trees and increase the concentration of tree sap to enhance cold resistance, but it cannot really prevent frost damage

Disadvantages of this method: due to long-term freezing damage, the temperature of the soil and the air next to the ground will continue to drop, and it is only very effective for short-term freezing damage

[0009] Although there are many ways to prevent the late spring cold, there are disasters every year in the area. The above methods cannot fundamentally solve the essential problem of temperature drop, and the effect of preventing the late spring cold is not ideal.
