Description

An intelligent greenhouse system TECHNICAL FIELD

[0001] The present application relates to the technical field of greenhouse, in particular to an intelligent greenhouse system. BACKGROUND

[0002] Glass greenhouse refers to a greenhouse using glass as lighting material, which belongs to one type of greenhouse shed. As a form with the longest service life, the glass greenhouse is suitable for use in various regions and under various climate conditions. The area and use mode of the glass greenhouse can be freely adjusted by the greenhouse owner. The smallest one is a courtyard leisure type, and the largest one has a height of more than 10 meters and a span of more than ten meters.

[0003] Generally, a sunshade system is arranged at the top of the glass greenhouse. When the intensity of sunlight is too large, the sunshade system is adjusted to reduce the light intensity on the plant leaves, so as to ensure the normal growth of the plants. The traditional greenhouse sunshade system uses a sunshade net to shade by adjusting the sunshade area. This way not only needs a complex support structure outside the top of the greenhouse, but also cannot achieve zero shading. The existing ventilation modes mainly include natural ventilation and forced ventilation. Regardless of the ventilation mode, an exhaust port and an air inlet port need to be arranged on the glass greenhouse. For most greenhouses, the exhaust port and the air inlet port are arranged around the glass greenhouse. This arrangement not only affects the appearance of the entire glass greenhouse and destroys the integrity of the glass curtain wall, but also has low aesthetic degree. On the other hand, the ventilation and air exchange speed and effect are not good, and the energy consumption is high. In addition, the existing glass greenhouse cannot well collect the heat in the hot air, and the hot air is mostly discharged and wasted. At night, a large amount of electric energy needs to be used for heating to maintain the temperature, resulting in high use cost. SUMMARY

[0069] Embodiment 1

[0070] As shown in Figures 1-7, an intelligent greenhouse system includes a greenhouse 1, which is provided with at least a ventilation system, an active energy storage system, a heat preservation system, and an intelligent shading system arranged on the top of the greenhouse;

[0071] The ventilation system includes an exhaust channel 6 arranged on the top and / or upper side wall of the greenhouse 1, the exhaust channel 6 is provided with a top opening window 7, and a fan is arranged at the exhaust channel 6; A plurality of ducts 8 are arranged below the side wall of the greenhouse 1, a wet curtain 9 is arranged in the duct 8, and an air inlet 10 is arranged opposite to the wet curtain 9, and a side opening window 11 is arranged at the air inlet 10;

[0072] The active energy storage system includes a groundwater tank 12 arranged below the greenhouse 1, the groundwater tank 12 is provided with a heat exchange pipeline assembly, a plurality of heat exchange air inlets are arranged above the greenhouse 1, and a plurality of heat exchange air outlets are arranged below the greenhouse 1, the heat exchange air inlets and the heat exchange air outlets are connected to the heat exchange pipeline assembly, respectively;

[0073] The intelligent shading system includes a shading plate assembly arranged above the roof of the greenhouse 1, the shading plate assembly automatically adjusts the light flux in the greenhouse according to the light demand of the plants, the adjustable shading plate can also be a photovoltaic panel, so that the excess light energy can be output for power generation without affecting the growth of greenhouse crops, and the solar energy is used to the maximum extent.

[0074] The intelligent greenhouse system provides a greenhouse that can automatically control temperature and light intensity, and can save the high temperature generated in the greenhouse in the form of energy storage, which can reasonably adjust the temperature in the greenhouse and obtain heat energy, so that the whole greenhouse is more environmentally friendly and low energy consumption, energy saving, and can form a self-circulating independent ecological system.

[0075] The active energy storage system can convert the heat of the high-temperature air in the greenhouse into water temperature and store it in the underground water tank 12 through the arrangement of the underground water tank 12 and the heat exchange pipeline assembly, and release low-temperature air at the same time, so that the temperature in the greenhouse can be maintained within the comfortable temperature range required for plant growth. In the process of air circulation, the air heat energy can be saved in another way. When in a low-temperature environment such as at night, the heat in the water can be exchanged out through air circulation to improve the temperature in the greenhouse at night, so that the temperature in the greenhouse can be maintained without consuming electricity.

[0076] The active energy storage system can work in different seasons. Whether in winter or in hot summer, the water temperature in the underground water tank can be adjusted by about 25-30 degrees Celsius through temperature storage, heat preservation and heat exchange. The water temperature of about 25-30 degrees Celsius can also be used as the best water temperature for warm water breeding. In winter, the greenhouse air will cool down quickly without the greenhouse effect. At this time, the heat energy in the hot water is circulated and released to the air to warm the air in the greenhouse and keep the temperature in the greenhouse within the range of not less than 15 degrees Celsius.

[0077] The ventilation system can more effectively control the temperature and air circulation in the entire greenhouse. After cooperating with the active energy storage system, it is more conducive to maintaining the temperature in the greenhouse within the temperature range required by plants. The exhaust channel 6 on the roof is arranged vertically, and the top opening window 7 arranged therein plays a role in exhaust ventilation and rain shielding during opening and closing, avoiding rainwater flowing into the room from the exhaust channel. The fan is arranged below the exhaust channel and at a certain distance from the exhaust channel. Through such arrangement, Bernoulli effect can be formed here to enlarge the air volume of the fan, which is conducive to rapid exhaust ventilation.

[0078] The air inlet 10 is arranged at the culvert 8 where the wet curtain 9 is arranged. On the one hand, when the air is inhaled, the air with a higher temperature can pass through the wet curtain to lower the temperature before entering the interior of the greenhouse. On the other hand, the culvert and the wet curtain are shielded to make the outside of the greenhouse not have an obvious air inlet, so that the appearance of the entire greenhouse is improved, and the space at the culvert can be fully utilized.

[0079] The intelligent sunshade system uses a deflectable sunshade plate assembly to adjust the light flux in the room. Under the condition of ensuring the light intensity requirement of plants, the sunshade plate assembly can be controlled to shield sunlight to protect plants from being damaged by excessive light, and also can be used to cool the greenhouse by shielding sunlight. By deflecting the angle between the sunshade plate assembly and the sunlight, zero sunshade or full sunshade can be achieved. Compared with the traditional sunshade net system, the sunshade plate assembly has more sunshade advantages and adjustability. If a photovoltaic panel is used as a sunshade component, it can also output electricity while achieving sunshade.

[0080] The ventilation system, active energy storage system, heat preservation system and intelligent sunshade system of the greenhouse can be used independently or complementarily, and have strong advantages in greenhouse indoor temperature control and heat energy utilization.

[0081] The exhaust air passage and the air inlet are mutually coordinated, and the heat exchange air inlet and the heat exchange air outlet are also mutually coordinated, so that low-temperature air flows into the greenhouse from the bottom and high-temperature air flows out of the greenhouse from the top, which conforms to the principle of air flow, and is beneficial to ventilation and temperature regulation. The top window and the side window are both electric glass windows and can be independently controlled according to the needs.

[0083] The appearance of the entire greenhouse 1 is relatively beautiful, especially when all the exhaust air passages 6 are arranged at the top of the greenhouse 1, there are no obvious exhaust air passages and windows around the greenhouse 1, and the entire greenhouse 1 is directly built with full-size curtain wall glass, which is beautiful and atmospheric.

[0084] The glass curtain wall and the glass roof both use tempered vacuum glass, which has high strength and thin thickness, and also has strong heat insulation capacity. The vacuum structure and the low-e coating technology can effectively prevent the transfer of indoor temperature and reduce the heat loss in the greenhouse, especially the heat loss in winter. The keel frame system is arranged on the indoor side, and the glass curtain wall has no metal parts exposed from the outside, and there is no heat conductor penetrating through the wall, especially the first, second, third and fourth connecting nodes for connection and installation, which avoids external metal parts and further avoids heat transfer of metal, thereby improving the heat preservation performance of the greenhouse.

[0085] The metal parts are mainly some metal pipes, frames, metal plates, bolts and other connecting parts connected with the keel frame system; the gaps at the connecting joints are treated for heat insulation and sealing, and the heat insulation and sealing structure mainly includes foam rods, weather-resistant sealant and sealing strips and other components.

The culvert 8 is a concrete structure and can be used as a part of the keel frame system support base. The arrangement of the culvert can keep it low, which is beneficial to the wet curtain to play a better role and avoid setting the wet curtain system on the glass curtain wall. The culvert 8 has a large space, which can accommodate the wet curtain 9 and allow the side opening window 11 to open outward. The window is not inwardly opened because the indoor side is provided with a glass curtain wall keel frame system to avoid motion interference caused by inward opening. In addition, inward opening will occupy the space of the greenhouse.

[0092] When the earth embankment slope is arranged, the outer side of the ground base of the greenhouse is provided with an outwardly horizontally extending extension connection structure.

[0096] The fan is arranged below the exhaust channel 6 and is kept a distance from the exhaust channel 6; through such an arrangement, Bernoulli effect can be formed here, thereby amplifying the air volume of the fan and facilitating rapid exhaust ventilation.

[0097] Further, the exhaust channel is a transparent channel, which is a glass channel or an acrylic channel, and the exhaust channel is arranged beyond the roof of the greenhouse; the glass channel is enclosed by a plurality of single-layer laminated tempered glass, and the thickness of the interlayer of the single-layer laminated tempered glass is not less than 0.76 mm. The glass channel made of single-layer laminated tempered glass can avoid blocking sunlight due to the arrangement of the exhaust channel, and the same type of building material is used for the greenhouse, which makes the appearance consistency and aesthetic better.

[0098] In other embodiments, as shown in FIG. 6, the peripheral wall of the exhaust channel 6 extends a hollow frame 32 at the top, each face of the frame 32 is hung with a swingable baffle 34 by a string 33, when wind blows from the direction of the baffle 34, the baffles 34 will stand up, and a negative pressure (Bernoulli effect) will be formed on the back of the baffle 34, which will drive the airflow in the air duct to move upward, thereby improving the exhaust speed and efficiency of the exhaust channel.

[0099] Specifically, the baffle 34 is connected to the lower part of the frame 8 through a rotating shaft, and the upper part of the frame 32 and the upper part of the baffle 34 are provided with ring holes, and the string 33 is connected through the ring holes.

A plurality of inclined baffles 16 are arranged in the heat exchange pipeline 15 along the air flow direction. The baffles 16 and the heat exchange pipeline 15 are both made of metal materials with excellent heat transfer performance. The baffles 16 can increase the contact area between the air and the metal, thereby increasing the heat exchange efficiency with the water. The heat exchange efficiency and effect are greatly improved without affecting the air flow speed and smoothness.

[0103] Further, as shown in FIG. 10, the heat exchange air inlet and the heat exchange air outlet are respectively provided with detachable filter screens 35. The filter screens 35 can prevent sundries from being sucked into the pipeline when air is sucked, so as to avoid adverse effects on the heat exchange pipeline assembly and affect the air circulation and heat exchange. The filter screens can be detached for replacement and maintenance.

[0104] In some embodiments, the high-positioned filter screen is further provided with a self-cleaning mechanism. Since the high-positioned filter screen is located at a high position and is inconvenient for manual cleaning, the self-cleaning mechanism is arranged to automatically clean the filter screen. For example, a rotatable rod body is arranged on the filter screen of a circular pipeline. A brush and / or a scraper are arranged on the rod body. The rod body is driven to rotate and move by a motor, so that the brush and / or the scraper clean the filter screen, so that the filter screen is kept clean and unobstructed.

A plurality of metal pipe supports are arranged in the underground water tank along the direction of the underground water tank. The heat exchange pipelines are arranged on the metal pipe supports. The cross-sectional dimension of the energy storage water tank is not less than 0.1 m. 2 The overall length of the energy storage water tank is not less than 30 m.

[0106] By arranging a plurality of heat exchange partitions in the heat exchange pipeline, not only the interior of the heat exchange pipeline is divided into a plurality of ventilation chambers, but also the contact area of the inflowing air with the partitions and the heat exchange pipeline is increased, which is beneficial to increase the heat exchange area of the air in the heat exchange pipeline with the cooling medium outside the heat exchange pipeline, greatly improves the heat exchange efficiency and effect without affecting the air flow speed and smoothness; moreover, the structure of the entire heat exchange pipeline is not complex, and is easy to manufacture and install.

[0107] The heat exchange partitions are arranged along the length direction, and a plurality of heat exchange partitions can multiply the surface area in the pipeline, which greatly increases the contact area of the air and the metal, and does not form an obstruction structure in the cross-sectional direction, without affecting the normal circulation of the air. The heat exchange pipeline and the heat exchange partitions are made of the same metal material, such as steel, aluminum or copper, and preferably made of aluminum pipe and aluminum plate, which has good heat transfer function, light weight and easy welding characteristics, facilitating manufacturing and installation.

[0108] The metal pipe support also has heat transfer capacity, which supports the heat exchange pipeline 15 without affecting the heat exchange; the bottom of the metal pipe support is connected to the bottom of the energy storage water tank through the bottom plate, and the upper part is provided with a support plate, which can conveniently install and fix the heat exchange pipeline and support it, and the periphery is water, which is beneficial to full heat exchange.

This structure can improve the heat preservation and waterproof performance of the entire underground water tank.

[0112] The underground water tank is provided with an insulation cover plate, which can close the underground water tank, reduce water evaporation, and even if there is evaporated water vapor, it will condense below the insulation cover plate and fall into the water tank, reducing water loss. The underground water tank can also be normally laid with a greenhouse floor, which has a certain thickness and can cover the water tanks; for greenhouses with aquatic plant cultivation or fish farming, the water in the water tank can also be used.

[0113] Further, as shown in FIG. 11, the roof 101 of the greenhouse 1 has a continuous high-low structure, the sunshade plate assembly includes a sunshade plate 17, and a traction rope 18 connected with the sunshade plate 17; one end of the sunshade plate 17 is rotatably installed at the valley bottom of the roof 101, the other end of the sunshade plate 17 is connected with the traction rope 18, a plurality of fixed pulleys 22 are arranged at the peak and valley of the roof respectively, the traction rope 18 is connected with the adjacent sunshade plate 17 after passing through the fixed pulley 22 at the peak, and the traction rope is folded back to the hoist assembly 21 after passing through the fixed pulley at the peak and the fixed pulley at the valley after sequentially connecting each row of sunshade plates 17, the hoist assembly 21 and the fixed pulley at the peak are respectively installed at the peak of the roof 101 through the second support 20. The fixed pulley at the valley is fixedly installed through a small pulley bracket.

[0114] Through the arrangement of the traction rope 18 and the plurality of fixed pulleys 22 arranged at high and low positions, each row of sunshade plates 17 can be connected in series, and the angle of deflection can be adjusted synchronously under the winding and unwinding of the hoist assembly 21, and a plurality of hoist assemblies 21 are not needed, and the hoist assemblies can be arranged on both sides or only on one side.

[0115] In some embodiments, as shown in FIG. 11, the valley bottom of the roof 101 is provided with a first support 19, the lower part of the sunshade plate 17 is connected with the first support 19 through a rotating shaft, and if a fixed pulley is arranged below, it can be arranged staggered or arranged at the neutral position of the rotating connection below the sunshade plate; the peak of the roof 101 is provided with a second support 20, the second support 20 is provided with a hoist assembly 21, the upper part of the sunshade plate 17 is connected with the hoist assembly 21 on one side of the peak through the traction rope 18, and the upper part of the sunshade plate 17 is connected with the hoist assembly 21 on the other side of the peak through the traction rope 18 or connected with a counterweight or connected with a fixed pulley.

[0116] For the sunshade 17, it needs to reciprocating deflection in a certain range, only one side of the traction rope can not meet the adjustment requirements, so the other side is also provided with a traction rope, as shown in Figure 11, the sunshade 17 is subjected to traction force (such as F1 and F2) at adjacent peaks, respectively, by changing the force of F1 and F2 to realize the deflection of the sunshade. F1 and F2 can be connected to the motor through the traction rope to realize the deflection of the sunshade, one of them can be connected to a fixed weight counterweight, the other can be controlled by the motor, or the steel wire rope and the fixed pulley can be used to connect each row of sunshades in series and then return to the winch assembly.

[0117] When the sunshade 17 is parallel to the sunlight, the sunshade 17 has the minimum sunshade rate, and can realize no sunshade; the maximum sunshade rate is related to the angle of incidence of the sun, and when the angle between the sunlight and the ground is less than 30 degrees, it can basically realize 100% sunshade, and when the angle between the sunlight and the ground is 90 degrees, the maximum sunshade coefficient is about 50%.

[0118] Further, as shown in Figure 12, the winch assembly 21 includes a winch shaft 2101 and a servo motor 2102 connected and driving the winch shaft 2101, and the winch shaft 2101 is installed on the second support 20 through a bearing seat 2103; the upper side of the sunshade 17 is provided with a plurality of connection holes or connection ring buckles connected to the traction rope; the servo motor 2102 drives the winch shaft 2101 to reverse, and the traction rope 18 is wound or released, so that the sunshade 17 is deflected, and the sunshade 17 can hover at any angle.

[0119] The sunshade 17 is a solar panel, and is provided with a battery energy storage system, and forms a hybrid energy storage system with the active energy storage system; the sunshade 17 is also provided with a light intensity sensor.

[0120] When the sunshade 17 is a solar panel, it can realize power output without affecting plant growth. At this time, the primary purpose of the sunshade is still sunshade, and the light intensity in the room is adjusted, but the light energy can be converted into electric energy in time during the sunshade process. For large greenhouses, the electric energy generated by the setting of these solar sunshades can completely meet the power consumption of the entire greenhouse. It should be noted that the angle of the sunshade 17 is adjusted without the primary purpose of absorbing sunlight to generate electricity.

[0121] The light intensity sensor can acquire light intensity value in real time, and the purpose is to control the direction and angle of the sunshade deflection according to the size of the light intensity value. For example, two support plates with an included angle are arranged above the sunshade, which can be staggered. One light intensity sensor is arranged on the front and back of each support plate, and the size of the sum of the light intensity values of the front and back of the two support plates is compared, and the direction of the sunshade deflection is determined according to the size of the sum of the light intensity values.

[0122] Further, the intelligent greenhouse system further comprises the following control mode:

[0123] During the operation of the greenhouse, when the room temperature is higher than the energy storage temperature, the active energy storage system sucks the hot air in the greenhouse from the heat exchange air inlet, discharges the cold air from the heat exchange air outlet after heat exchange, and stores the heat energy; when the room temperature is lower than the energy storage temperature, the active energy storage system sucks the cold air in the room from the heat exchange air inlet, discharges the hot air from the heat exchange air outlet after heat exchange, and supplements the room temperature.

[0124] According to the most suitable temperature range Tmin-Tmax in the greenhouse set for different crops, the real-time temperature T in the greenhouse is determined, and the size relationship between T and Tmax and the size relationship between T and Tmin are determined to determine whether the top window and the side window are opened, whether the wet curtain and the fan need to be started, and whether the heat exchange pipe assembly needs to be opened for heat exchange.

[0125] Specifically, it is judged whether T is greater than Tmax, if yes, it is judged whether the top window and the side window are opened, if yes, the wet curtain and the fan are opened, if no, the top window and the side window are opened.

[0126] If T is not greater than Tmax, it is continuously judged whether T is greater than Tmin, if yes, it is judged whether the wet curtain and the fan are opened, if yes, the wet curtain and the fan are closed.

[0127] If it is judged that T is less than Tmin, if yes, it is judged whether the wet curtain and the fan are opened, if yes, the wet curtain and the fan are closed, and the top window and the side window are closed.

[0128] By linking the ventilation function with the greenhouse temperature control, the power consumption required for greenhouse temperature regulation is minimized, and the temperature in the greenhouse can be accurately controlled by using a reasonable air supply and exhaust system. In particular in summer, the system can timely control the opening of the ventilation equipment, adjust the environmental temperature in the greenhouse, maintain the environmental comfort, and meet the needs of normal growth of crops.

[0129] The intelligent sunshade system is adjusted according to the light intensity and temperature changes in the greenhouse, the real-time detected light intensity in the greenhouse is S1, the most suitable light intensity range in the greenhouse is Smin-Smax according to different crops, the sizes of S1 and Smax and the sizes of S1 and Smin are judged to adjust the deflection direction of the sunshade plate assembly.

[0130] Specifically, as shown in FIGS. 13-15, support plate one 1701 and support plate two 1702 are arranged above the sunshade plate 17, and there is an included angle a between the support plate one 1701 and the support plate two 1702; a light intensity sensor 1703 is arranged on each of the front and back surfaces of the support plate one 1701, and is denoted as A1 and A2; a light intensity sensor 1703 is also arranged on each of the front and back surfaces of the support plate two 1702, and is denoted as B1 and B2; A1, A2, B1 and B2 together form a composite light intensity sensor unit; by comparing the sum of the light intensity values of A1+A2 with the sum of the light intensity values of B1+B2, it can be known that the sunshade plate is deflected in which direction to obtain greater or smaller sunshade effect (or light shielding degree), that is, the deflection direction of the sunshade plate is determined according to the size of the sum of the light intensity values. If the value of A1+A2 is relatively large, the sunshade plate is deflected to the A direction (the direction of the support plate one) to obtain greater light shielding effect, and vice versa to obtain smaller sunshade effect.

[0131] It is judged whether S1 is greater than Smax, if not, then jump to the next step,

[0132] If yes, then compare the sum of the light intensity values of A1+A2 with the sum of the light intensity values of B1+B2, if the sum of the light intensity values of A1+A2 is greater than the sum of the light intensity values of B1+B2, then adjust the sunshade plate to deflect in the direction of the support plate one, if the sum of the light intensity values of A1+A2 is less than the sum of the light intensity values of B1+B2, then adjust the sunshade plate to deflect in the direction of the support plate two;

[0133] It is judged whether S1 is less than Smin, if not, then it indicates that the position of the sunshade plate is appropriate, and no adjustment is made,

[0134] If yes, then compare the sum of the light intensity values of A1+A2 with the sum of the light intensity values of B1+B2, if the sum of the light intensity values of A1+A2 is greater than the sum of the light intensity values of B1+B2, then adjust the sunshade plate to deflect in the direction of the support plate two, if the sum of the light intensity values of A1+A2 is less than the sum of the light intensity values of B1+B2, then adjust the sunshade plate to deflect in the direction of the support plate one.

[0135] Through the above method, the deflection direction and angle of the sunshade plate can be more accurately controlled, the sunshade plate can be adjusted according to the position of sunlight and the light intensity in the room, and the automation and intelligence level is high.

[0173] The deflection of the sunshade can be adjusted more conveniently through the cooperation of the nut block 37 and the screw rod 36, and this adjustment mode has a relatively simple structure, and is not limited to the type of sunshade, and can also realize the deflection of the sunshade to the slope direction on both sides of the trough.

[0174] Referring to the states of the left and right sunshades in FIG. 24, the roof slope is stationary, the screw rod 36 rotates under the action of the driving motor, so that the nut block 37 moves along the screw rod 36, since the size of the sunshade 17 is unchanged, the screw rod 36 and the sunshade 17 will be deflected at the same time, for example, the nut block 37 moves along the screw rod 36 to the direction of the long screw rod located at the peak, driving the sunshade 17 to deflect to the left slope, the screw rod 36 itself will also deflect upward, so that the triangular area will gradually become smaller, that is, the deflection angle adjustment of the sunshade 17 under the push-pull action of the long screw rod is realized, and vice versa.

[0175] While embodiments of the application have been shown and described, it is to be understood that the embodiments described are merely exemplary of the principles and application of the present application. Numerous modifications and adaptions can be effected without departing from the spirit and scope of the present application, which is not limited to the exact construction and arrangement described. It is intended, therefore, to cover all modifications and adaptions that fall within the scope of the claims and their equivalents.
