Description

Technical Field

[0001] The invention relates to the technical field of agricultural breeding greenhouses, and in particular to a double-layer greenhouse with heating and cooling functions. Background Art

[0002] The material used to cover the greenhouse is plastic film. It is suitable for covering a large area because it is light, has good light transmission and heat preservation properties, is highly plastic and inexpensive. It can also be made of lightweight frame materials, is easy to build and shape, can be locally selected, requires less construction investment, and has higher economic benefits. It can also resist natural disasters, prevent cold and keep warm, resist drought and waterlogging, plant crops earlier, delay planting, extend the growth period of crops, and achieve the goals of early maturity, late maturity, increased and stable production. It plays an important role in resisting low temperature, drought and wind and sand hazards, especially in high-cold areas, sandy wastelands and arid areas.

[0003] At present, most breeding greenhouses are single-layer shed structures, that is, a single structure covered with shed film. In some windy and sandy areas or areas with low temperatures, single-layer shed structures have low strength and the risk of being damaged and deformed by wind and sand. In addition, in order to ensure sufficient thermal insulation, the height of the single-layer shed structure is generally high, which raises the center of gravity of the shed and further causes the stability of the shed to deteriorate. Therefore, those skilled in the art hereby propose a technical solution of a double-layer shed with heating and cooling functions to solve the problem. Summary of the invention

[0004] In view of the defects of the existing breeding greenhouses mentioned in the above background technology that the thermal insulation performance needs to be improved and the lack of active temperature control function; therefore, a technical solution of a double-layer greenhouse with heating and cooling functions is provided, including a double-layer greenhouse fixed on the ground, and an insulation blanket structure laid on the outer surface of the double-layer greenhouse, and heating and cooling ventilation pipes passing through and fixed inside the double-layer greenhouse; the double-layer greenhouse includes an outer frame structure and an inner frame structure, and the outer frame structure is sleeved on the outer surface of the inner frame structure.

[0005] Among them, the outer scaffolding structure includes several arch rods arranged at equal distances, and several longitudinal pull rods connecting the arch rods.

The gap between the outer scaffolding structure and the inner scaffolding structure constitutes a partition layer, which in turn improves the thermal insulation inside the greenhouse. At the same time, the upper greenhouse structure can improve the overall strength of the scaffolding. And because the thermal insulation curtain is controlled by a self-propelled thermal insulation curtain roller to cover the outer surface of the outer scaffolding structure, and a set of thermal insulation curtain mechanisms are also added to the outer surface of the inner scaffolding structure, the temperature inside the outer scaffolding structure can be better preserved.

[0012] In the above-mentioned technical solution of a double-layer greenhouse with heating and cooling functions, preferably, the airflow heating assembly includes a tank body fixed on the side wall of the inner cavity of the tube body, a support column fixed in the inner cavity of the tank body, and a plurality of motor heat rods arranged in a circular array and fixed on the outer ring surface of the support column.

[0031] The heating and cooling ventilation pipe fitting 3 includes a pipe body 31, a closable waterproof cap movably arranged at the air inlet port position on the top of the pipe body 31, and an airflow heating component fixed at the middle position of the inner cavity of the pipe body 31, and a forced air intake component located below the airflow heating component is fixed at the bottom of the inner cavity of the pipe body 31.

[0032] Gable columns 1101 are fixed on both sides of the longitudinal tie rod 1103, and an opening 1104 for the pipe body 31 to pass through and be fixed is provided in the middle section of the intersection of the arch rod 1102 and the longitudinal tie rod 1103. Channel steel support walls 1201 are fixed to the left and right side walls of 12023, and a gap of 40cm-60cm is provided between the top surface of the arch frame 1202 and the inner surface of the arch rod 1102, thereby forming a heat-insulating compartment.

[0033] The thermal insulation quilt mechanism 2 includes two groups of thermal insulation curtains 21 arranged on the outer surfaces of the arch rod 1102 and the longitudinal beam 1203, and the outer surfaces of the arch frame 1202 and the longitudinal beam 1203 are covered with self-propelled thermal insulation curtain rollers 22 that cooperate with the thermal insulation curtains 21, wherein the self-propelled thermal insulation curtain rollers 22 have a gap of 30cm-40cm between each other, for the pipe body 31 to be fixed between the self-propelled thermal insulation curtain rollers 22.

[0034] The closable waterproof cap at the air inlet port position at the top of the tube body 31 includes: an electric-controlled linear slide rail 32 fixed on the left and right side walls of the tube body 31, and a slider 33 movably arranged inside the slide groove of the electric-controlled linear slide rail 32, and an L-shaped traction rod 34 is fixed to the side wall of the outer surface of the slider 33, a waterproof brim 35 is fixed to the top surface of the L-shaped traction rod 34, and a blocking block 36 is fixed to the bottom surface of the waterproof brim 35. The waterproof brim 35 is in an inverted bowl shape as a whole, and the lower half of the blocking block 36 is inserted into the upper port of the tube body 31, wherein a rubber sealing ring is fixed to the outer ring surface of the blocking block 36 by an adhesive to seal the gap between the outer ring of the blocking block 36 and the port of the tube body 31.

[0035] The airflow heating component includes a tank body 39 fixed on the inner cavity side wall of the tube body 31, a support column 37 fixed in the inner cavity of the tank body 39, and a plurality of motor heat rods 314 arranged in a circular array and fixed on the outer ring surface of the support column 37.

[0036] According to the above-mentioned preferred technical solution, the workflow of the technical solution is described as follows:

[0037] The arch rod 1102 and the longitudinal tie rod 1103 are connected to each other vertically and horizontally to form an outer scaffolding system, and the longitudinal crossbeam 1203 and the arched frame 1202 are connected to each other vertically and horizontally to form an inner scaffolding system.

At the same time, the upper greenhouse structure can improve the overall strength of the scaffolding. And because the thermal insulation curtain quilt 21 controls the self-propelled thermal insulation curtain roller 22 to cover the outer surface of the outer scaffolding structure 11, and a set of thermal insulation quilt mechanisms 2 are also added to the outer surface of the inner scaffolding structure 12, the temperature inside the outer scaffolding structure 11 can be better preserved.

[0038] When the temperature inside the outer shelf structure 11 cannot maintain an effective temperature threshold and the cultured animals inside the outer shelf structure 11 need ventilation, the electric linear slide rail 32 controls the slider 33 to move upward to pull the L-shaped traction rod 34 upward, driving the blocking block 36 that originally sealed the upper port of the tube body 31 upward. The servo fan 310 drives the fan blades 312 to draw air into the tube body 31 so that the airflow passes through the inside of the tank body 39. After the motor heat rod 314 is powered on to heat the airflow, the hot airflow is discharged into the inside of the outer shelf structure 11.
