Energy-saving seedling cultivation greenhouse

Abstract

The invention relates to an energy-saving seedling raising greenhouse, which comprises a greenhouse. A thermal insulation wall is arranged on the back part of the greenhouse; and a solar water heater is arranged on the top of the thermal insulation wall. A plurality of groups of heating radiators are arranged inside the greenhouse; a hot water reservoir is arranged below the ground level of the greenhouse; a hot water outlet pipe is connected with the right end of the hot water reservoir; the water outlet of the hot water outlet pipe is connected with a water inlet of a water delivery pipe; and a circulating pump is connected in series on the water delivery pipe. The water outlet of the water delivery pipe is respectively connected with the solar water heater, a radiating pipe network and the water inlet of the heating radiator groups through electric stop valve pipes connected in series. The solar water heater, the radiating pipe network and the water outlet of the heating radiator groups are respectively connected with the water inlet of a water return pipe through pipes; the water outlet of the water return pipe is connected with the water inlet of a hot water inlet pipe; and the water outlet of the hot water inlet pipe is connected with the left end of the hot water reservoir. The invention aims to provide the energy-saving seedling raising greenhouse which has energy conservation, environmental protection and convenient use and does not need special heating in a cold season.

Description

technical field [0001] The invention relates to a greenhouse utilizing solar energy. Background technique [0002] Greenhouses can effectively improve the utilization rate of farmland, but due to the poor thermal insulation effect of existing greenhouses, in the cold winter in the north, vegetable greenhouse seedlings mostly use coal, firewood and other fuel boilers to heat the greenhouse every day, not only The cost is high, troublesome, it increases the labor intensity of relevant personnel, the temperature is not easy to control, and the mineral energy consumed also increases the pollution to the environment. If the operation is not done properly, it is easy to cause smoke hazards or gas poisoning of personnel. With the vigorous development of my country's vegetable industry, there is an objective need to build vegetable seedling greenhouses that are energy-saving, emission-reducing, and easy to operate, and are suitable for use in rural areas.
