Abstract
The heliogreenhouse irrigation system is composed of heliogreenhouse and solar collector, in which the rear wall of the heliogreenhouse is semi-underground heat-insulating wall and is connected with arched beams at 38-48 deg. of elevation angle, and the ratio of its daylighting area to the span of heliogreenhouse is 1 : 1.0-1.2. The solar collector is placed on the rear wall of the heliogreenhouse, and the collector tube is connected with irrigation facilities being in the heliogreenhouse. By selecting the daylighting angle and position of solar collector said invention solves the problem of reasonably using solar energy to raise the temp. of water and use warm water to irrigate the field.
Description
The present invention relates to a kind of greenhouse by solar heat irrigation system, belong to gardening plant protection technology field.
The temperature of greenhouse by solar heat production in winter directly influences the yield and quality of fruits and vegetables, especially ground temperature is more remarkable to the influence of vegetables, the raising of ground temperature is difficult to the raising of temperature again, the agro-technician has studied a lot of insulations and has heated measure at present, as improve the greenhouse heat-insulating material, use artificial heating irrigated land etc., but because the cost problem still is difficult to promotion and implementation; " 93222973 " patent disclosure plastic tunnel use the device of solar water drip irrigation, its basic structure is at the plastic tunnel top solar thermal collector to be set to compile hot water, finishes the task that soil is heated up and irrigates.This device is owing to be installed in the top of booth, certainly will want the sunlight of shield portions, thereby reduced the availability of sunlight in the booth, the greenhouse by solar heat that has insulated wall for the northern area extensive application, relative altitude also is unsuitable at the top heat collector being set, and does not still possess the practical application condition.
The object of the present invention is to provide a kind of greenhouse by solar heat irrigation system,, rationally utilize solar energy that water is heated, irrigate the fields with warm water again and improve sight greenhouse ground temperature problem to solve by selecting the position that is provided with of light transmissivity of Sunlight Greenhouse angle and solar thermal collector.
Technical scheme of the present invention is achieved in that this greenhouse by solar heat irrigation system, form by greenhouse by solar heat and solar thermal collector, wall is the semi-underground type insulated wall behind the greenhouse by solar heat, it is 38～48 ° that back wall connects the arched girder elevation angle, light transmissivity of Sunlight Greenhouse face arched girder is the arch-shaped shape, daylighting face is 1: 1.0～1.2 with greenhouse span ratio, and solar thermal collector places on the back wall of greenhouse by solar heat, and thermal-collecting tube connects the irrigating facility in the greenhouse.
The back wall that is chosen as of the better lighting angle of described greenhouse by solar heat connects 42 ° at the arched girder elevation angle, and the light transmissivity of Sunlight Greenhouse face is 1: 1.167 with greenhouse span ratio.
In order to reach the insulation purpose, wall is designed to middle rowlock wall behind the described greenhouse by solar heat, fill insulant material such as slag, perlite, sawdust etc. in the empty bucket.
The solar thermal collector of described greenhouse by solar heat irrigation system is that many group plastic tube serial or parallel connections are formed, and is fixed in apart from the back wall of the above greenhouse by solar heat of ground 50CM, and heat collector connects the irrigating facility in the greenhouse, as drip irrigation pipe etc.
The arched girder in described sight greenhouse adopts the silicon magnesium base composite material to make; The thermal-collecting tube of solar thermal collector is selected plastic tube.
Actual test result of the present invention proves, use the water temperature in the greenhouse by solar heat irrigation system thermal-collecting tube to be significantly higher than the running water water temperature, peak about 14 o'clock in the afternoon, can exceed 25～31 ℃ of running water water temperatures, weakening along with intensity of illumination afterwards, water temperature is by descending, and water pipe discharges the heat that absorbs gradually.
Describe technology contents of the present invention in detail below in conjunction with drawings and Examples:
Fig. 1 is a greenhouse by solar heat irrigation system structural representation
Fig. 2 is a greenhouse by solar heat collector structure schematic diagram
Fig. 3 is a greenhouse by solar heat irrigation system heat collector scheme of installation
Among the figure:
1, body of wall 2, heat-insulation layer 3, arched girder 4, plastic film 5, heat collector 6, winter protection plate
7, water intaking valve 8, plastic tube 9, outlet valve 10, carriage
Heat collector can adopt the shell and tube parallel connection also can adopt straight tube to add the cascaded structure of elbow during practical application, and thermal-collecting tube can be selected black or 1/2 (sunny slope) black, and in order to guarantee the daylighting effect, heat collector should be higher than canopy implants height in Hou Qiang fixed position, greenhouse.
