[0042] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0043] Please refer to Figures 1-10 , specifically including the following embodiments: Embodiment one:

[0044] A full-automatic greenhouse for cultivating butterfly orchids includes a greenhouse main body 1, which includes a three-layer arched roof covering system 10, a four-around double-wall structure 11 and a shed head sunlight plate structure 12. The three-layer arched roof covering system 10 is composed of an outer arched layer 101, a first inner arched layer 102 and a second inner arched layer 103.

[0045] The outer arched layer 101 is covered with 15-silk PO film, and the first inner arched layer 102 and the second inner arched layer 103 are both covered with 8-silk PO film, forming two stable air layers. By taking advantage of the low thermal conductivity of air, the heat is effectively insulated, ensuring the stability of the environment in summer and winter, effectively avoiding the freezing damage of flowers, and having stronger airtightness, which can slow down the rapid emission of heat in the shed at night, avoid the problem of leaf wilting caused by large temperature difference, and save energy, which is beneficial to the growth of butterfly orchids.

[0046] Each layer of film is fixed on the greenhouse framework through aluminum alloy card slots and self-locking film pressing lines, forming a closed structure with high heat preservation and high light transmission. The advantages of PO film are high transparency, strong continuous dew drop capacity, strong heat preservation performance, long service life, high tensile strength, anti-static, non-dust sticking, and reduction of disease and pest damage.

[0047] The four-week double-wall structure 11 includes an outer 5mm tempered coated glass curtain wall 110 and an inner PO film sliding system 111. The tempered coated glass curtain wall 110 is installed on an aluminum alloy frame through a sealing rubber strip; the inner PO film system 111 is installed on the built-in sliding rail and connected to the electric roller, which can be opened or closed along the sliding rail to form an adjustable third air layer with the tempered coated glass curtain wall 110. Tempered glass can withstand harsh weather impact, reduce the risk of breakage, and reduce the harm to personnel and crops in time; the coating function can allow visible light to be efficiently transmitted while reflecting part of the infrared and ultraviolet light, reducing the temperature rise in the shed in summer and reducing the risk of leaf aging; it can also reflect the long-wave radiation emitted in the shed, reduce heat conduction loss through glass, and reduce heat loss; the thickness of 5mm single-layer glass balances the light transmittance and light weight, while reducing the cost of glass.

[0048] The inner film makes up for the shortcoming of single-layer glass in heat preservation, and can form a "glass-air-film" double air layer with glass, further reducing heat loss by using the low thermal conductivity of air; the sealing property of the film is strong, which can lock the water vapor in the shed, reducing humidity fluctuations caused by the poor sealing property of single-layer glass, and the PO film can avoid internal condensation, allowing water vapor to flow down the film surface, keeping the leaf surface dry and reducing the incidence of disease.

[0049] The safety, light transmittance controllability and durability of the 5mm single-layer tempered coated glass 110, combined with the heat and moisture preservation of the PO film, have three advantages of safety and economic balance, fine environmental management and maintenance cost optimization.

[0050] The shed head sunlight plate structure 12 includes double-layer hollow sunlight plates 121 on the greenhouse gable ends, which are 8mm thick, fixed to the main framework through special H-shaped connectors, and have ventilation windows at the top driven by electric push rods. The double-layer sunlight plate has high and uniform light transmittance, and the double-layer hollow structure contains an air cavity, which has lower thermal conductivity than single-layer glass and film, reducing heat conduction at the shed head in winter and reducing the risk of crop freezing damage. Moreover, the double-layer sunlight plate is strong and can effectively reduce damage, resist aging, and prolong service life. In addition, the structure is light, reducing the load pressure, and has strong plasticity, facilitating installation and modification, auxiliary energy saving, and reducing environmental regulation cost.

[0051] The greenhouse body 1 is provided with a light system 2, the light system 2 includes a movable seedbed 20 and a reflection and absorption mechanism 21, two groups of the reflection and absorption mechanism 21 are symmetrically arranged below the movable seedbed 20, are arranged at a certain horizontal angle, generally 10°~15°, the reflection and absorption mechanism 21 includes two shafts 201 that are symmetrically arranged, the two shafts 201 are wound with reflective cloth 202 and light-absorbing cloth 203, the reflective cloth 202 and the light-absorbing cloth 203 are located on the two sides of the shaft 201, and the two are connected head to tail, the shaft 201 can rotate under the drive of a driving source to make the reflective cloth 202 face the flower seedlings below or the light-absorbing cloth 203 face the flower seedlings below, so that the mode of reflection or light absorption is switched, the driving source can be a servo motor, the shaft 201 is installed on a support frame 204, the support frame 204 is drivingly connected with a first motor 205, and the first motor 205 drives the reflective cloth 202 and the light-absorbing cloth 203 to revolve to adjust the angle of reflection or light absorption.

[0052] The present application realizes the function switching and angle adjustment of the reflective cloth 202 and the light-absorbing cloth 203 by arranging the light system 2 in the greenhouse body 1 and arranging the switchable reflection and absorption mechanism 21 below the movable seedbed 20.

[0053] The light supplement mode is as follows: when the light is insufficient, the reflective cloth 202 can be unfolded and the angle is adjusted to the best, the light passing through the gap between plants and the redundant light of the LED light supplement lamp is efficiently reflected back to the back of the plant leaf, this part is the most prone to light deficiency area in traditional cultivation, which greatly improves the light energy utilization rate, reduces the opening time and energy consumption of the light supplement lamp, promotes the photosynthesis and uniform growth of the plant, and prevents the plant from growing too long.

[0054] The light absorption mode is as follows: in summer or when the light is too strong, the light absorption cloth mode can be switched to, the redundant heat and light are absorbed, the heat accumulation in the area below the seedbed is prevented to form a high-temperature area, the root system is prevented from overheating and disease breeding, and the internal and external sunshade systems are cooperated to work, so that the three-dimensional and fine intelligent control of the greenhouse light environment is realized.

[0055] Specifically, when the driving source is started to rotate the shaft 201, the positions of the reflective cloth 202 and the light-absorbing cloth 203 can be adjusted, when the first motor 205 is started, the support frame 204 rotates along the center, so that the shaft 201, the reflective cloth 202 and the light-absorbing cloth 203 rotate as a whole, the angle of reflection or light absorption is adjusted, the light utilization rate is improved, and the space between the reflective cloth 202 and the light-absorbing cloth 203 can flow air, so that the air circulation is not blocked after the reflection and absorption mechanism 21 is arranged.

[0056] Among them, it needs to be emphasized that the traditional light reflection mode is to lay the light reflection ground film, on the one hand, it is only suitable for ground planting, not suitable for seedbed planting in greenhouse, on the other hand, the light reflection ground film only has the function of reflecting light, especially in summer, when the light is too strong, and when the light is not needed, the light reflection ground film does not have the adjusting function. In addition to using the light absorption cloth 203 to absorb heat, the whole structure can be rotated to the vertical state, the ventilation range below the seedbed is larger, the air circulation is not hindered, and the heat accumulation is reduced.

[0057] Among them, the light reflection cloth 202 and the light absorption cloth 203 are consistent in size, can be located below the seedling as a whole, and can also occupy half of the area and other combination forms by adjusting the rotation distance, so as to realize the scene of part of light reflection and part of heat absorption, and adjust the proportion of light and heat absorption.

[0058] As a further explanation of the embodiment, in order to further increase the utilization rate of light and avoid slow air flow, an adjusting assembly 3 is arranged between the light reflection cloth 202 and the light absorption cloth 203, the adjusting assembly 3 comprises a cam 30, the cam 30 is arranged in a square box 31, the square box 31 is fixed with the support frame 204, the cam 30 is overlapped with a push plate 32, the push plate 32 moves along the inner wall of the square box 31, the push plate 32 is fixed with a roller 33, the structure composed of two groups of push plates 32 and rollers 33 is symmetrically arranged about the square box 31, the roller 33 moves along the channel opened in the square box 31, and the two rollers 33 are overlapped with the light reflection cloth 202 and the light absorption cloth 203 respectively.

[0060] The first connecting shaft 34 is rotated by rotating the twist plate 35, and the first connecting shaft 34 can also be driven to rotate by increasing a driving device, so that the cam 30 rotates, the push plate 32 moves under the cam 30, and then the roller 33 moves under the light reflection cloth 202 or the light absorption cloth 203. On the one hand, the light can be focused, the utilization rate of light is improved, on the other hand, the space range between the light reflection cloth 202 and the light absorption cloth 203 is increased, which is beneficial to air flow and heat accumulation reduction, and further reduces the accumulation of dust and water stains on the surface.

[0061] Among them, the adjusting assembly 3 can be arranged in multiple groups, so that the light utilization rate of the light reflection cloth 202 and the light absorption cloth 203 is higher, and the focusing and directional reflection of light are realized locally, and the reflected light is shot to a certain part of the seedling, and the self-cleaning function of the light reflection cloth 202 and the light absorption cloth 203 is realized.

[0062] As a further explanation of the present embodiment, the push plate 32 is fixed with the first spring 36, and the first spring 36 is fixed with the inner wall of the square box 31, and the first spring 36 can pull the roller 33 back to the original position.

In order to reduce the damage caused by pulling and stretching, the contraction assembly 4 is further arranged on the cam 30 to optimize the above-mentioned problem, and the contraction assembly 4 comprises a supporting rod 41, one end of the supporting rod 41 is overlapped with the cam 30, the supporting rod 41 is slidingly connected to the supporting frame 204, and the other end of the supporting rod 41 is bearingly connected to a second connecting shaft 42, the second connecting shaft 42 is coaxially fixed with the rotating shaft 201, and the second connecting shaft 42 is movably and rotationally connected to the supporting frame 204.

Water source heat pump "extracts" heat from the water body or "releases" heat to the water body through the phase change of refrigerant. The specific process is as follows:

[0088] Heat source / cold source exchange: when heating, the circulating water absorbs heat from the water source, enters the evaporator, and transfers heat to the liquid refrigerant, which evaporates into gas; when cooling, the circulating water brings the heat in the room to the condenser, and the gaseous refrigerant condenses into liquid and releases heat, and the circulating water takes the heat back to the water source;

[0089] Compression / expansion: gaseous refrigerant is compressed by compressor into high-temperature and high-pressure gas, and then reduced by expansion valve to complete the cycle in evaporator. It has the advantages of high energy efficiency, low operating cost, stable operation, not affected by extreme weather, outstanding environmental protection and small environmental impact.

The controller can automatically control the start and stop of the high-pressure pump, as well as the time and frequency of spraying, etc. according to the preset parameters; the sensor is used to monitor the humidity, temperature, dust concentration and other parameters of the environment, so that the system can be intelligently adjusted;

[0092] Filter system: composed of multiple filters, which can effectively remove impurities, particles, rust and other impurities in water, to ensure that the nozzle is not blocked and prolong the service life of the equipment;

[0093] Spray system: composed of spray pipeline and nozzle. Spray pipeline is generally made of corrosion-resistant and high-pressure stainless steel or engineering plastic material, which delivers high-pressure water to each spray point; the nozzle is the key component for water atomization, which is made of wear-resistant and corrosion-resistant ceramic or stainless steel, and has various types such as fan-shaped nozzle and conical nozzle, which can achieve different spray shapes and coverage.

[0094] The circulating fan generates directional airflow by rotating the blades, breaks the air stratification, and promotes the formation of closed circulation of air in the greenhouse. It reduces temperature difference, optimizes gas distribution, and promotes crop growth; improves energy utilization efficiency and reduces operating cost.

[0095] LED plant light with support and movable track, according to the crop height adjustment light source distance, realize the light source position flexible adjustment. Through the sensor and controller, automatic adjustment of light time, intensity, realize intelligent management such as according to the natural light intensity automatic start-stop, time period adjustment power. Can break through the natural light limit, control growth cycle, improve crop quality, energy saving and intelligent.

[0096] The core of water and fertilizer integration is to dissolve fertilizer in water, and to accurately and uniformly deliver water and nutrients to the vicinity of crop roots through irrigation system, so as to realize the purpose of watering and water and fertilizer at the same time. According to the needs of different growth stages of crops, the concentration and amount of water and fertilizer solution are flexibly adjusted to avoid excess or insufficient nutrients. Main components:

[0097] Water source;

[0098] Head hub: it is the core control part, including water pump, filter, pressure gauge, flow meter, etc.;

[0099] Fertilizer injection device: used for injecting fertilizer into irrigation system;

[0100] Intelligent water and fertilizer machine: can accurately control the concentration, amount and time of fertilizer, with high automation degree;

[0101] Water distribution network: responsible for delivering water and fertilizer solution to the field;

[0102] Irrigation terminal: equipment for directly supplying water and fertilizer to crops, such as drip irrigation head, spray tank head, micro-sprinkler, etc., which can improve water and fertilizer utilization rate, promote crop growth, reduce environmental pollution and save labor cost.

[0103] Working principle of industrial dehumidifier:

[0104] Suction of humid air: the fan sucks the humid air in the environment into the dehumidifier;

[0105] Cooling and condensation: the humid air flows through the evaporator, and the water vapor in the air is pre-condensed into liquid water droplets, which adhere to the surface of the evaporator and then drop into the water pan and are discharged through the drain pipe;

[0106] Heating: the dry air after removing water flows through the condenser and is heated to slightly higher than the ambient temperature, and then is sent back to the room;

[0107] Circulation: through the continuous suction, condensation, heating and discharge cycle, the water vapor content in the indoor air is gradually reduced to achieve the dehumidification effect. Industrial dehumidifier has the advantages of high dehumidification efficiency, intelligent control and high automation degree.

[0108] All systems are controlled by an AI intelligent control center, which receives data from sensor networks such as temperature, humidity, light, and CO2 sensors throughout the greenhouse, analyzes and makes decisions through an AI algorithm platform, and issues control instructions to the following actuators to achieve full-automatic closed-loop regulation.
