technical field

The utility model relates to a greenhouse, in particular to a solar energy spanning greenhouse which is used in the northern cold region and does not need any heating equipment.

Background technique

To produce vegetables, flowers, fruit trees and other temperature-loving plants in the cold winter in the northern region, the existing imported large-scale greenhouses and domestic greenhouses need to increase heating equipment to burn oil or coal to make the plants grow, which is a waste of energy. And destroyed the environment. Even so, it is barely growing, and the production effect cannot be achieved, let alone the benefit. There is no greenhouse that can fully use solar energy to produce in winter, and in summer, the problem of overheating in large greenhouses cannot be solved. In order to solve the problem of not consuming energy, but also allowing plants to grow normally in the cold winter and obtain higher benefits, we must first start with designing a reasonable structure for the greenhouse. Only when the structure of the greenhouse is reasonable can energy be saved, the economic benefits of users and growers can be improved, and it can also play a good role in protecting the ecological environment.

A set of arch frames is set above each unit, and the two ends of the arch frames are fixed on the beams. It is made of vertical bricks with 2 to 8 spaces, 24cm-100cm thick, 5cm-25cm thick polystyrene board pasted outside the wall, the lighting angle α is above 40°, the wall height is 2m-9.2m, and the ridge height is 3.6m-10.8 m, the unit span is 6m-16m, and the depth of the greenhouse below the ground is 30cm---100cm.

The utility model also includes the following scheme: the greenhouse is covered with a rainproof paper quilt and a rainproof cotton quilt, and is equipped with an electric roller shutter machine, and doors and windows are installed on the east and west walls of the greenhouse.

The solar multi-span greenhouse can be disassembled into a single-seat greenhouse, a two-seat greenhouse, a three-seat greenhouse... and its performance is the same as that of an all-solar greenhouse. This kind of greenhouse can be designed into different structural models and different greenhouse angles in different regions according to the natural climate characteristics of northern my country and the user's production performance requirements to improve the performance of the greenhouse and make it the most reasonable use of solar energy.

The utility model has the following advantages: 1. Good lighting in winter, since the lighting angle α on the south side of the greenhouse is more than 40°, the solar energy can be fully utilized in winter, both direct sunlight and scattered light can be fully utilized. From winter solstice to spring equinox, more than 75% to 95% of the light enters the greenhouse. When the light is good, energy is saved and the ecological environment is protected. 2. The wall of this greenhouse is designed to be 24cm---100cm, 2 spaces to 8 spaces, and a polystyrene board made of magnesia with a thickness of 5cm---25cm is pasted on the back of the wall to prevent freezing and heat preservation. The greenhouse wall of this structure Body insulation performance is very good. The cold-proof ditch is set on the south side of the greenhouse and is built with bricks to form a small wall of 24cm wide by 50cm deep. The polystyrene board with a depth of 50cm and a thickness of 5cm can be buried outside the wall. The east and west gables of the greenhouse are buried with polystyrene boards with a depth of 50 cm and a thickness of 5 cm to prevent freezing. 3. It adopts a cultivation mode with a large row spacing of 3 meters, and is equipped with an electric roller shutter system, which makes the operation easier and more convenient. Planting various vegetables, the ventilation and light transmission are very good, and the plants will grow well. 4. The steel roof truss is designed by two methods of welding anti-rust paint or galvanized assembly, which is both beautiful and practical. The design of the entire greenhouse is equal to or lower than the cost of ordinary greenhouses.

The solar continuous-span greenhouse adopts an angle of 7°-8° to the west, and sits on a north-south lighting surface. The span and height are determined by the user, and the wall is designed to have different thicknesses according to the climatic conditions of each region. The lighting angle is designed according to the geographical location and climatic conditions of each region. In the past, the lighting angle was generally 23.5°, but now it is improved to a minimum of 40°, so as to ensure the entry of light and heat energy and meet the needs of winter production. The solar energy spanning greenhouse can be disassembled into a single-seat greenhouse with the same performance, which is more suitable for the use and development of farmers at the present stage, and can allow plants to grow normally in winter. The improvement of the greenhouse cover is that one is made of kraft paper, covered with a layer of plastic film inside and outside to prevent rain and snow, and the other is made of cotton curtain made of rainproof cloth, with a layer of frost-proof foam and a layer of waterproof plastic film inside. Better play a rain, snow insulation effect.

The solar energy spanning greenhouse has overcome various difficulties through years of experiments and is now mature. In the coldest winter in northern my country - 30°C - 40°C, the indoor temperature can reach above 30°C on sunny days; above 20°C on cloudy days, and keep above 10°C at night. According to the needs of different varieties of planting plants, the temperature can be adjusted in the morning and evening when the curtains are placed. This solar multi-span greenhouse is a large-scale greenhouse that does not need heating. It is not only used for seedling cultivation and production of vegetables, but also for seedling cultivation and production of large plants such as flowers and fruit trees. Tall fruit trees can be planted inside.
