Energy-saving effect-improving vegetable greenhouse

Abstract

The invention relates to an agricultural facility, in particular to an energy-saving effect-improving vegetable greenhouse, which comprises a greenhouse frame (1), a greenhouse membrane (4), a greenhouse quilt (6) and a thermal insulation wall (5). The energy-saving effect-improving vegetable greenhouse is characterized in that the greenhouse frame (1) is a magnesite pipe, a water spraying pipe (2) is arranged in the magnesite pipe, a spray head (3) is installed below the magnesite pipe, the upper portion of the thermal insulation wall (5) is provided with a solar energy water tank (7), and the thermal insulation wall (5) is formed by two layers of magnesite plates (17). A hollow water-containing cavity (8) is arranged between the two layers of magnesite plates (17), a polyphenyl foam thermal insulation layer (10) is arranged at the back of the thermal insulation wall (5), and the solar energy water tank (7) is communicated with the water spraying pipe (2) of the greenhouse frame (1) and the hollow water-containing cavity (8) in the thermal insulation wall (5) through water pipes and valves. The energy-saving effect-improving vegetable greenhouse has the advantages that the magnesite greenhouse frame is sturdy and durable and low in cost and can replace a steel pipe and a bamboo material. A magnesite wall is good in heat absorption performance, can be very thin and occupies little area. The solar energy water tank arranged on the thermal insulation wall can collect and store energy, the water pipes are arranged in the greenhouse frame and under the ground, solar-powered hot water can be used to water crops, water can be saved, and temperature in the greenhouse can be improved.

Description

technical field [0001] The invention relates to an agricultural facility, namely an energy-saving and efficiency-enhancing vegetable greenhouse. Background technique [0002] The production of winter vegetables in the north requires greenhouses. Existing vegetable greenhouses are mostly made of steel pipes or bamboo and wood materials, covered with transparent plastic film, and equipped with thermal insulation quilts. There is a thermal insulation wall on the north side of the greenhouse. The main disadvantages of this kind of vegetable greenhouse are its high cost and poor thermal insulation performance. The main reason for the high cost is that the cost of the scaffold is relatively high. The use of steel pipes has a long service life, but the one-time investment is too high. The use of bamboo and wood materials requires a small one-time investment, but the service life is short and requires frequent replacement. The overall cost is also high. , and cutting down bamboo h...

Problems solved by technology

Obviously, the heat storage efficiency of the earth wall is relatively low, and the heat in the greenhouse is mostly insufficient. In the severe cold season, it is necessary to burn fire to supplement the heat

In addition, the existing greenhouses mainly rely on ground irrigation to meet the water demand of the crops. The water is more, and it is all deep well water with a lower temperature, which not only increases the cost, but also reduces the ground temperature and the temperature inside the greenhouse.
