Room temperature regulating device for greenhouse

Abstract

The invention discloses a room temperature regulating device for a greenhouse, relates to the field of electrics and aims at providing a device capable of automatically preserving heat for the greenhouse. In order to achieve the aim, the invention adopts the following technology: blast heating equipment is locally and additionally arranged in the greenhouse; the blast heating equipment is composed of temperature regulating equipment, a temperature sensing device and an electric heating cable, wherein the electric heating cable is controlled by the temperature regulating equipment, the temperature sensing device is also connected with the temperature regulating equipment, the electric heating cable immediately generates heat after being electrified to achieve the aim of raising the temperature of the greenhouse, and the temperature sensing device has the effect of detecting the temperature inside the greenhouse; the electric heating cable is arranged inside the greenhouse, the temperature sensing device is also placed inside the greenhouse, and the temperature regulating equipment is arranged outside the greenhouse; and during application, the required temperature value is firstly set on the temperature regulating equipment as required, and when the natural temperature value in the greenhouse is lower than an artificially-set temperature value, the temperature regulating equipment can be automatically electrified, and the electric heating cable can generate heat after being electrified for 10s. The room temperature regulating device has the advantage of automatic heat preservation.

Description

technical field [0001] The invention belongs to the technical field of facility agriculture, and in particular relates to a device for regulating room temperature in a greenhouse. Background technique [0002] Because the vegetable greenhouse has the advantages of high yield, quick effect, less vegetable diseases and insect pests, and can advance or prolong the market time of vegetables, it is welcomed by farmers and widely used. But in winter, especially in the north, the greenhouse can only be left idle due to the cold winter. Although there are a few farmers who use soil heaters for heating, due to the high cost and little economic benefit, farmers have to stay at home during the winter season, which greatly affects their income. [0003] At present, there are many places that maintain normal production through rectification of greenhouses. The rectification measures mainly include: [0004] Close the greenhouse in the warm morning and evening, cover it with a cover, ch...
