Embodiment 1

[0024] Such as Figure 1~Figure 3The shown solar heat storage greenhouse of the present invention includes a spherical frame, and components such as a light-transmitting thermal insulation layer are arranged outside the spherical frame. Several polygonal frame structures formed by bolt balls and steel pipes (such as triangles, pentagons, and hexagons, preferably using the principle of the stabilization effect of triangles, each part of the greenhouse skeleton is composed of triangular steel pipe members, and the structure is extremely stable.) form a spherical frame , surrounding the bottom of the spherical frame is surrounded by a circle of phase-change thermal storage wall panels 6, the height of the phase-change thermal storage wall panels is 1.5m, and a living space 5 is provided between the phase-change thermal storage wall panels 6 and the spherical frame (it can be built into a triangle or trapezoidal structure). Each arc-shaped structural unit is provided with inner a...

Embodiment 2

[0033] The other structures are the same, and the improved soil is composed of the following components: peat soil 45kg, plant ash 25 kg, calcium hydroxide 15 kg, iron powder 5 kg, starch 10 kg, fiber-type fermentation powder 1 kg, sodium tetraborate 0.05 kg, fertile field Powder or guano 20 kg, potassium permanganate 1 kg.

[0034] The transparent foam heat storage layer is composed of the following components: 20kg of α-dilute organic expanding agent (AEO), 20kg of hydroxyethyl cellulose, 10kg of sodium dodecylsulfonate, 5kg of sodium stearate, and 60kg of water.

Embodiment 3

[0036] The other structures are the same, and the improved soil is composed of the following components: peat soil 42kg, plant ash 20kg, calcium hydroxide 10kg, iron powder 3kg, starch 7kg, fiber-type fermentation powder 0.5kg, sodium tetraborate 0.03 kg, fertilizer powder or bird droppings 15kg, potassium permanganate 0.5kg.

[0037] The transparent foam thermal storage layer is composed of the following components: α-dilute organic expanding agent (AEO) 15kg, hydroxyethyl cellulose 15kg, sodium dodecylsulfonate 7kg, sodium stearate 4kg, water 50kg.

Abstract

A solar thermal storage greenhouse, which solves the problems of the existing spherical greenhouses such as narrow application range, small illumination area, low effective land use area, poor sealing, poor heat preservation, easy to be blown away by strong winds, easy to collapse with snow accumulation, and poor earthquake resistance. It includes a spherical frame with a light-transmitting thermal insulation layer outside the spherical frame. The technical points are: the spherical frame is composed of several polygonal frames, and a circle of phase-change thermal storage wall panels surrounds the bottom of the spherical frame. Phase-change thermal storage There is a living space between the wall panel and the spherical frame; the spherical frame is provided with inner and outer light-transmitting insulation layers, and a transparent foam heat storage layer is filled between the two light-transmitting insulation layers; the inner and outer light-transmitting insulation layers are made of transparent PVC material; the vertical direction in the spherical frame is divided into multi-layer planting areas by several mesh laminates, and the planting areas of each layer are planted without soil. It has the advantages of intelligent control, low construction cost and high land utilization rate.

Description

technical field [0001] The invention relates to the field of plant cultivation greenhouses, in particular to a solar heat storage greenhouse and a construction method thereof. The invention is mainly applicable to layering and planting various crops with different plant heights in a three-dimensional space by making full use of solar heat storage and adopting a soilless cultivation technique. Background technique [0002] Facility agriculture is a symbol of the overall level of a country's agriculture and one of the most dynamic industries in the world today. By the end of 2003, the protected cultivation area had exceeded 2 million hectares, becoming the largest protected cultivation country in the world. The main purpose of the greenhouse is to produce agricultural products during the non-cultivation season. In order to get the best indoor conditions, the greenhouse must be equipped with suitable heating and cooling systems to adapt to the extreme climate changes outdoors,...
