An intelligent regulation system for crop growth environment

Abstract

The application relates to the technical field of regulation systems, in particular to an intelligent regulation system for the growth environment of crops. The system comprises a heat collection box, a light-transmitting heat preservation cover arranged above the heat collection box, and a heat preservation shell arranged below the heat collection box. The height of the heat collection box is adjusted by an extension mechanism to enter the light-transmitting heat preservation cover or the heat preservation shell. The bottom of the light-transmitting heat preservation cover is connected with the top of the heat preservation shell. When the heat collection box is irradiated, heat is absorbed, and the heat collection box is lowered into the heat preservation shell for heat preservation. The heat preservation is carried out in a closed environment, so that heat is actively released at night. The inside of the heat collection box is filled with liquid, and the outside is a black heat absorption layer, so that a large amount of heat can be quickly stored. When the heat is released, the upper end surface of the heat collection box is exposed outside the heat preservation structure, so that the heat can be continuously and long-term released. The heat storage capacity can change the height of the heat collection box and increase the amount of stored liquid.

Description

Technical Field

[0001] This invention relates to the field of control system technology, and more specifically to an intelligent control system for crop growth environment. Background Technology

[0002] Greenhouse covering materials such as plastic film and glass typically have good light transmittance and heat insulation properties. During the day, sunlight shines through the covering material into the greenhouse, where it is absorbed by plants, soil, and air and converted into heat energy, gradually raising the temperature inside. Due to the greenhouse's enclosed or semi-enclosed structure, this heat is not easily lost to the outside, thus achieving heat storage to a certain extent.

[0003] At night, as the outside temperature gradually decreases, the heat inside the greenhouse is slowly released due to the insulating effect of the covering material, preventing a sharp drop in temperature and providing a relatively stable temperature environment for crop growth. This method helps reduce damage to crops caused by excessive diurnal temperature variations, thereby improving crop yield and quality.

[0004] To improve nighttime heat retention, existing technologies employ methods such as adding one or more layers of insulation material, like straw mats or thermal blankets, on top of the existing greenhouse covering to reduce heat loss; or constructing double- or multi-layer greenhouse structures to enhance insulation by adding air layers. While this passive approach to delaying heat loss is energy-efficient, it cannot actively provide heat into the greenhouse, requiring additional insulation measures on cold nights to ensure normal crop growth. Summary of the Invention

[0005] This invention provides an intelligent control system for the crop growth environment, the purpose of which is to actively provide heat to the greenhouse at night.

[0006] The above objectives are achieved through the following technical solutions:

[0007] A smart control system for crop growth environment includes a heat collection box, a light-transmitting heat-insulating cover above the heat collection box, and a heat-insulating shell below the heat collection box. The height of the heat collection box can be adjusted by a telescopic mechanism to enter the light-transmitting heat-insulating cover or the heat-insulating shell. The bottom of the light-transmitting heat-insulating cover is connected to the top of the heat-insulating shell.

[0008] The outer wall and upper surface of the solar collector are coated with a black coating. The solar collector is made of metal and contains liquid.

[0009] The solar collector box is made of copper, aluminum alloy or stainless steel.

[0010] The top of the solar collector is equipped with a liquid inlet, and the bottom of the solar collector is equipped with a liquid outlet. There are two detachable covers on the solar collector, located inside the liquid inlet and the liquid outlet respectively.

[0011] The liquid is water, salt water, or an antifreeze based on ethylene glycol or propylene glycol.

[0012] The light-transmitting heat-insulating cover is a double-layered vacuum glass cover with an opening at the bottom.

[0013] The light-transmitting heat-insulating cover is fixed in position by suspension or support feet.

[0014] The telescopic mechanism is either an electric telescopic cylinder or a hydraulic cylinder.

[0015] An insulation sleeve is fixed to the lower end of the insulation shell, and the insulation sleeve is fitted onto the telescopic end of the telescopic mechanism. An insulation pad is fixed to the upper end of the telescopic mechanism, and the insulation pad is fixed to the lower end of the heat collection box.

[0016] The outer layer of the insulation shell is made of polyethylene, and the inner layer is made of rock wool or glass wool, or the outer layer of the insulation shell is made of stainless steel, and the inner layer is made of multiple layers of cotton cloth.

[0017] The beneficial effects of the intelligent control system for crop growth environment of this invention are as follows:

[0018] The heat is absorbed by the heat collection box inside the transparent insulation structure when exposed to sunlight, and then falls into the insulation shell for insulation. During insulation, it is in a closed environment so that the heat is actively released at night.

[0019] The inside of the heat collection box is filled with liquid, and the outside is a black heat-absorbing layer, which allows it to quickly store a large amount of heat.

[0020] When releasing heat, the upper surface of the collector box is exposed outside the insulation structure, thus allowing for continuous and prolonged heat release. The heat storage capacity can be increased by altering the height of the collector box and increasing the amount of liquid it stores. Attached Figure Description

Detailed Implementation

[0030] A smart control system for crop growth environment, reference Figures 1 to 3 The solar collector 11 is made of metal and includes a rectangular container and a plate that can be detachably connected to the upper end of the rectangular container, thereby forming a closed structure.

[0031] Furthermore, the outer surfaces of the four longitudinal walls of the cuboid container, as well as the upper surface of the plate, are all coated with a black coating, such as metallic powder paint; the collector box 11 contains liquid.

[0032] Furthermore, the top of the heat collection box 11 is provided with a liquid inlet, and the bottom of the heat collection box 11 is provided with a liquid outlet. Two covers 12 are detachably connected to the heat collection box 11, which are located in the liquid inlet and the liquid outlet respectively, thereby sealing the liquid inlet and the liquid outlet.

[0033] To further explain, in combination Figures 4 to 5 A light-transmitting heat-insulating cover 21 is provided above the heat collector box 11, and a heat-insulating shell 31 is provided below the heat collector box 11. The bottom of the inner wall of the light-transmitting heat-insulating cover 21 is connected to the top of the outer wall of the heat-insulating shell 31 to form a heat-insulating container surrounding the heat collector box 11. A telescopic mechanism 41 is installed at the bottom of the heat collector box 11, which passes through the heat-insulating shell 31. The heat collector box 11 can be adjusted in height by the telescopic mechanism 41 to enter the light-transmitting heat-insulating cover 21, or adjusted in height to squeeze into the heat-insulating shell 31.

[0034] This system is used in conjunction with greenhouses and placed inside the greenhouse. The long side of the heat collection box 11 is parallel to the long side of the greenhouse, preferably centered inside the greenhouse. The light-transmitting heat-insulating cover 21 is fixed in position by suspension; or, a support foot 22 is fixed to each of the four corners at the bottom of the light-transmitting heat-insulating cover 21.

[0035] Furthermore, the lower edge of the heat collection box 11 is provided with a chamfered surface to facilitate the insertion of the heat insulation shell 31.

[0036] Furthermore, the light-transmitting heat-insulating cover 21 is a double-layered vacuum glass cover with an opening at the bottom, which may include a frame and vacuum double-layered glass fixed to each surface of the frame.

[0037] Furthermore, the outer layer of the thermal insulation shell 31 is made of polyethylene, and the inner layer is made of rock wool or glass wool.

[0038] Furthermore, the telescopic mechanism 41 is an electric telescopic cylinder or a hydraulic cylinder. The movable end of the telescopic mechanism 41 is set upwards. A heat insulation pad 42 is fixed to the upper end of the movable end of the telescopic mechanism 41. The heat insulation pad 42 is fixed to the lower end of the heat collection box 11. The movable end of the telescopic mechanism 41 passes through the heat insulation shell 31 from bottom to top.

[0039] An insulation sleeve 32 is fixedly connected to the lower end of the insulation shell 31. The insulation sleeve 32 is fitted onto the telescopic end of the telescopic mechanism 41 and the shell.

[0040] An elastic support mechanism is fixed to the lower end of the heat insulation shell 31. When the heat insulation shell 31 is subjected to downward pressure, the elastic support mechanism contracts, creating a gap between the heat insulation shell 31 and the light-transmitting heat insulation cover 21, releasing heat. The upper surface of the heat collection box 11 continuously releases heat into the greenhouse.

[0041] Furthermore, in combination Figure 5 and 7 The elastic support mechanism includes a support frame 51, on which a straight rod 52 is inserted, allowing the straight rod 52 to slide vertically relative to the support frame 51. A limiting block 53 is fixed to the upper and lower ends of the straight rod 52, and a spring 54 is fitted onto the straight rod 52. The upper end of the spring 54 abuts against the lower end of the upper limiting block 53, and the lower end of the spring 54 abuts against the upper end of the support frame 51.

[0042] The spring 54 provides an upward force to the upper limiting block 53, causing the upper end of the lower limiting block 53 to abut against the lower end surface of the support frame 51. Four elastic support mechanisms are provided, with the tops of four straight rods 52 fixed near the four corners of the lower end of the insulation shell 31, maintaining the connection between the insulation shell 31 and the light-transmitting insulation cover 21. During sunlight, after the heat collection box 11 has finished collecting heat, it descends into the insulation shell 31 for insulation. At night, the heat collection box 11 descends further, pressing down on the insulation shell 31, further compressing the spring 54. This causes the insulation shell 31 to move downwards, creating a gap between itself and the light-transmitting insulation cover 21, thereby gradually releasing heat.
