Description

Technical Field

[0001] The present invention relates to the technical field of energy-saving and environmental protection control for greenhouse environments, and specifically to an energy-saving and environmental protection control system for agricultural biological greenhouse environments. Background Art

[0002] A greenhouse environment control system refers to an automated system used to monitor and regulate the greenhouse environment and provide optimal growth conditions for crops, providing good temperature, humidity, light, and carbon dioxide concentration in the greenhouse, which can effectively improve crop yield and quality. Currently, in response to the country's call for green and environmentally friendly production, greenhouse agriculture production is gradually developing towards energy-saving and environmental protection, converting solar energy, wind energy, and geothermal energy into electricity to supply energy to the control system instead of traditional fossil fuels, reducing resource consumption and labor costs.

[0003] Most current control systems achieve energy-saving and environmental protection effects by installing photovoltaic panels on the greenhouse roof and using photovoltaic power generation for energy supply. However, due to the wide coverage area of the photovoltaic panels, installing them on the greenhouse roof greatly blocks the sunlight for the crops inside the greenhouse, and only the sunlight on both sides of the greenhouse and artificial lighting can be relied on. To address this problem, a corrugated roof has been designed on the market, with photovoltaic panels installed on one side of the V-shaped corrugation for power supply and transparent panels installed on the other side for convenient lighting. However, the splicing installation cost of the photovoltaic panels and the transparent panels is high, and the transparent panels are all installed obliquely, with a small coverage area, resulting in a sharp increase in the material consumption of the transparent panels on the roof. There is a problem that it is difficult to achieve both good lighting inside the greenhouse after installing the photovoltaic panels and low installation costs in the existing energy-saving and environmental protection control systems; in addition, the environment where greenhouses are used in the northwest region is drier, and the humidity regulation inside the greenhouse has higher requirements and is used more frequently compared to other regions. The existing humidity control system inside the greenhouse relies on a long-distance pipeline to connect multiple spray heads for unified spray humidification. However, when multiple spray heads are blocked due to impurities in the water flow, the maintenance time cost is relatively high, and due to the long pipeline, the water pressure in the spray heads farther away from the water pump is smaller when multiple spray heads spray water simultaneously, resulting in inconsistent water spray amounts.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] 1. In this energy-saving and environmental protection control system for agricultural biological greenhouse, by setting the outer greenhouse wall, hollow frames are installed on both the left and right sides of the greenhouse main body, and two rows of photovoltaic panels arranged vertically are installed between adjacent two hollow frames. During the day, the electric telescopic rod extends, and the electric telescopic rod pushes the photovoltaic panel to rotate outward around the first pin shaft, so that several photovoltaic panels expand relative to the greenhouse main body, making the photovoltaic panels fully exposed to sunlight. At night, the electric telescopic rod contracts to pull the photovoltaic panels to fold up, covering the gap between adjacent hollow frames, forming a second layer of greenhouse wall outside the greenhouse main body, achieving the effect of heat preservation for the greenhouse at night, reducing heat loss. By installing the photovoltaic panels on both sides of the greenhouse main body, instead of the traditional installation method on the top, during the day, the light shines directly from above the greenhouse main body, which can provide sufficient light intensity for the crops inside the greenhouse main body without the need for additional artificial lighting enhancement. Moreover, the conversion rate of solar energy when the photovoltaic panels expand is not inferior to the installation method on the top, and the operation difficulty of installing the photovoltaic panels on the side is smaller and the cost is lower.

[0018] 2. In this energy-saving and environmental protection control system for agricultural biological greenhouse, by setting the hollow frame and the mounting plate, the bottom plate is installed on the bottom concrete through embedded steel bars. After covering the greenhouse main body on the skeleton, the edges on both sides of the greenhouse main body are clamped between the bottom plate and the mounting plate, and the mounting screws pass through the mounting plate and the greenhouse main body and are connected to the screw holes, so that the hollow frame is installed on the bottom plate through the mounting plate, which not only realizes the rapid installation of the hollow frame, but also can quickly clamp and seal both sides of the greenhouse main body, maintaining the airtightness of the environment inside the greenhouse main body.

[0019] 3. In this energy-saving and environmental protection control system for agricultural biological greenhouse, by setting the hollow frame and the water collecting tank, the water collecting tank receives the rainwater flowing down from the top on both sides of the greenhouse main body. The rainwater flows into the interiors of several hollow frames after being filtered by the filter screen in the water collecting tank, and finally flows into the water storage tank through the inlet pipe for standby. Among them, the hollow frame is used as the main support of the outer greenhouse wall and is also used for installing the photovoltaic panels, and is also used for collecting and guiding rainwater, directly collecting and utilizing rainwater to save water resources.

[0020] 4. The energy-saving and environmental protection control system of the agricultural biological greenhouse environment is provided with a humidity control mechanism. After the microprocessor receives the signal of the controller, the humidity control operation is started. The micro push rod is extended, and the plug is pushed into the water outlet through the movable block. The plug pushes the block to move up and out of the slot. The inner cavity of the water-passing steel pipe is connected with the plug through the water inlet groove. The internal water flows from the plug into the bellows and the fixed pipe, and finally sprays out from the nozzle to increase the humidity of the environment inside the greenhouse body. After the humidity control in the area is completed, the motor drives the rotating shaft to rotate, and the rotating shaft drives the gear to rotate. The gear rotates in the tooth groove to drive the upper clamp seat and the lower clamp seat to move on the water-passing steel pipe, and the humidity of other areas is adjusted in turn. This single-nozzle walking zone spraying method reduces the number of nozzles from several to one, which can greatly reduce the time cost of maintenance when the nozzle is blocked, and only one water outlet is opened on the water pipe at a time. Therefore, no matter which area is sprayed, the water pressure is consistent, and the humidity control amount in multiple areas can be kept consistent.

[0021] 5. The energy-saving and environmental protection control system of the agricultural biological greenhouse environment is provided with an upper clamp seat and a lower clamp seat. By pressing the shifting blocks on the upper clamp seat and the lower clamp seat to approach each other, the upper clamp seat and the lower clamp seat can be moved away from each other around the first pin shaft, thereby achieving the clamping effect of the upper clamp seat and the lower clamp seat, facilitating the rapid disassembly and assembly of the upper clamp seat and the lower clamp seat, and the humidity regulating mechanism can be quickly removed from the water-passing steel pipe for maintenance.

[0034] As Figures 1 to 8 shown, the energy-saving and environmental protection control system for the agricultural biological greenhouse of this embodiment includes a framework 1 and a greenhouse main body 2 installed on the outer side of the framework 1. The greenhouse main body 2 is a transparent film or plate-like object covering the framework 1 of a traditional greenhouse. A connecting frame 3 is welded to the inner side wall of the framework 1. A water-passing steel pipe 4 is welded to the side of the connecting frame 3 away from the framework 1. The water-passing steel pipe 4 is installed on the framework 1 through the connecting frame 3. The water-passing steel pipe 4 is made of stainless steel to avoid water flow corrosion. A humidity-adjusting mechanism 5 is movably clamped on the outer side of the water-passing steel pipe 4. A control box 6 is installed on the inner wall of one of the frameworks 1 at the rearmost side, serving as the automatic processing center of the control system. A water storage mechanism 8 is installed on the inner wall of one of the frameworks 1 at the foremost side for collecting and storing rainwater. An outer greenhouse wall 7 is installed on the outer side wall of the greenhouse main body 2, serving as the heat preservation and reinforcement structure on the left and right sides of the greenhouse main body 2. Tooth-shaped grooves 41 are formed on the upper surface of the water-passing steel pipe 4. A pipe joint 42 is connected to the front side of the water-passing steel pipe 4. Water outlet holes 43 are formed at the bottom of the water-passing steel pipe 4. A slot 44 is formed at the top of the water outlet hole 43. The outer diameter of the slot 44 is larger than that of the water outlet hole 43, so that when a plug 45 is inserted into the slot 44, the water outlet hole 43 is completely covered. A plug 45 is arranged inside the slot 44. Limiting grooves 47 are formed inside the water-passing steel pipe 4 on the left and right sides of the slot 44. A limiting rod 46 is connected to the bottom of the plug 45. A spring 48 is sleeved on the outer side of the limiting rod 46 inside the limiting groove 47. The spring 48 is clamped inside the limiting groove 47 and is compressed when the limiting rod 46 moves upward;

[0035] The humidity regulating mechanism 5 comprises an upper clamping seat 51 and a lower clamping seat 52. A groove 53 is provided on one side of the upper clamping seat 51 and the lower clamping seat 52 where they are close to each other. A ball 54 is connected in a rolling manner inside the groove 53. There are multiple grooves 53 and multiple ball 54. After the upper clamping seat 51 and the lower clamping seat 52 are clamped on the water-passing steel pipe 4, the ball 54 contacts the outer wall of the water-passing steel pipe 4, reducing the friction between the upper clamping seat 51 and the lower clamping seat 52 and the water-passing steel pipe 4, making it convenient for the gear 511 to drive the upper clamping seat 51 and the lower clamping seat 52 to move. A shift block 55 is integrally connected to one side of the upper clamping seat 51 and the lower clamping seat 52. A connecting block 56 is connected to one side of the two shift blocks 55 where they are close to each other. A first pin shaft 57 is provided between the two connecting blocks 56. A torsion spring 58 is sleeved on the outer side of the first pin shaft 57. When the two shift blocks 55 are close to each other, the torsion spring 58 generates elastic force, and the upper clamping seat 51 and the lower clamping seat 52 move away from each other.

[0036] Specifically, the blocking block 45 is cylindrical, and the blocking block 45 is movably connected to the slot 44. The outer surface of the blocking block 45 is coated with an elastic coating, which is used to seal the gap between the blocking block 45 and the water outlet 43 and the slot 44. The limiting rod 46 is cylindrical with a L-shaped longitudinal section. The limiting rod 46 forms a sliding connection with the limiting groove 47. When the spring 48 is in a normal stretched state, the limiting rod 46 is fully inserted into the limiting groove 47. After the blocking block 45 loses the thrust of the insert tube 523, the spring 48 rebounds and pulls the limiting rod 46 downward in the limiting groove 47. The limiting rod 46 pulls the blocking block 45 downward and inserts it into the slot 44, thereby achieving an automatic blocking effect on the water outlet 43.

[0037] Furthermore, the side where the upper clamp seat 51 and the lower clamp seat 52 are close to each other is in a semicircular shape, and the inner diameter dimensions of the upper clamp seat 51 and the lower clamp seat 52 are compatible with the outer diameter dimensions of the water-passing steel pipe 4. The upper clamp seat 51 and the lower clamp seat 52 form a rotational connection through the first pin shaft 57. By pressing the shifting blocks 55 on the upper clamp seat 51 and the lower clamp seat 52 to approach each other, the upper clamp seat 51 and the lower clamp seat 52 can be moved away from each other around the first pin shaft 57 and clamped on the water-passing steel pipe 4, which is convenient for the rapid disassembly and assembly of the upper clamp seat 51 and the lower clamp seat 52, and the humidity regulating mechanism 5 can be quickly removed from the water-passing steel pipe 4 for maintenance. After the upper clamp seat 51 and the lower clamp seat 52 are clamped on the water-passing steel pipe 4, the ball 54 contacts the outer wall of the water-passing steel pipe 4.

[0038] Further, a gear 511 is installed inside the upper clamping seat 51. A rotating shaft 512 penetrates through the middle of the gear 511. One end of the rotating shaft 512 is installed with a bearing 513. The other end of the rotating shaft 512 extends out from the side wall of the upper clamping seat 51 and is connected with a motor 514. The motor 514 is installed on the side wall of the upper clamping seat 51. The shaft end of the motor 514 is connected with the rotating shaft 512. After the upper clamping seat 51 and the lower clamping seat 52 clamp the water-conducting steel pipe 4, the gear 511 is inserted into the tooth groove 41 and meshes with the tooth groove 41. The gear 511 is rotationally connected with the upper clamping seat 51 through the rotating shaft 512. When the motor 514 drives the rotating shaft 512 to rotate, the rotating shaft 512 drives the gear 511 to rotate. The gear 511 rotates in the tooth groove 41, while the water-conducting steel pipe 4 is welded and fixed. Therefore, the gear 511 will drive the upper clamping seat 51 and the lower clamping seat 52 to move on the water-conducting steel pipe 4 under the reverse force, and perform humidity adjustment on other areas in turn, realizing the walking type zoned spraying of the single nozzle 529.

[0039] Further, a fixed seat 521 is connected to the bottom of the lower clamping seat 52. An activity groove 522 is opened inside the lower clamping seat 52. An insertion pipe 523 is arranged inside the activity groove 522. The inside of the insertion pipe 523 is hollow. A water inlet groove 524 is opened on the side wall of the top of the insertion pipe 523. After the insertion pipe 523 is inserted into the water outlet hole 43 to push up the plug 45, the top of the insertion pipe 523 is communicated with the inner cavity of the water-conducting steel pipe 4 through the water inlet groove 524. Activity blocks 525 are connected to the left and right side walls of the insertion pipe 523. Micro push rods 526 are connected to the bottoms of the two activity blocks 525. The micro push rods 526 are installed in the fixed seat 521. The telescopic ends of the micro push rods 526 are connected to the bottoms of the activity blocks 525, and are used to push the activity blocks 525 to lift and lower in the activity groove 522, thereby driving the insertion pipe 523 to lift and lower. The micro push rods 526 are electrically connected to the microprocessor 5210 through a circuit. A corrugated pipe 527 is connected to the bottom of the insertion pipe 523. The corrugated pipe 527 is used to adapt to the lifting and lowering of the insertion pipe 523. The bottom of the corrugated pipe 527 is inserted into the inside of the fixed seat 521 and is connected with a fixed pipe 528. The fixed pipe 528 is bent at a right angle and extends out from the side wall of the fixed seat 521 and is connected with a nozzle 529. This walking type zoned spraying method of the single nozzle 529 reduces the number of nozzles 529 from several to one. When the nozzle 529 is blocked, the maintenance time cost can be greatly reduced. Moreover, only one water outlet hole 43 is opened on the water-conducting pipe each time. Therefore, the water pressure size of the spray in any area is the same, and the humidity adjustment amount of multiple areas can be kept consistent. A microprocessor 5210 is installed inside the fixed seat 521 on the side away from the nozzle 529 of the fixed pipe 528. Wireless signal transmission is realized between the microprocessor 5210 and the controller 61 through a wireless communication module. A power supply battery 5211 is installed inside the fixed seat 521 on one side of the microprocessor 5210, and supplies power to the motor 514 and the micro push rods 526. The power supply battery 5211 is electrically connected with a charging port 5212.

[0040] Furthermore, the outer diameter of the insert pipe 523 is matched with the inner diameter of the water outlet hole 43, the insert pipe 523 is movably connected to the water outlet hole 43, and the outer surface of the insert pipe 523 is coated with an elastic coating for sealing the gap between the insert pipe 523 and the water outlet hole 43. There are several water outlet holes 43, and they are equidistantly arranged at the bottom of the water-passing steel pipe 4. The water-passing steel pipe 4 is connected with the inner cavity of the insert pipe 523 through the water inlet groove 524, and the insert pipe 523 is connected with the fixed pipe 528 through the bellows 527. After the insert pipe 523 pushes the block 45 to move up and disengage from the slot 44, the inner cavity of the water-passing steel pipe 4 is connected with the insert pipe 523 through the water inlet groove 524, and the internal water flows from the insert pipe 523 into the bellows 527 and the fixed pipe 528, and is finally sprayed out from the nozzle 529 to increase the humidity of the environment inside the greenhouse body 2.

[0041] Furthermore, a controller 61 is installed inside the control box 6, and a photovoltaic battery 62 is installed inside the control box 6 below the controller 61 for storing the electric energy converted by the photovoltaic panel 79. A humidity sensor 63 is installed on the upper surface of the control box 6 for monitoring the air humidity and soil humidity of the environment inside the greenhouse body 2. A charging cavity 64 is provided inside the control box 6 below the photovoltaic battery 62, and a charging plug 65 is provided inside the charging cavity 64. The charging plug 65 is plugged into the charging port 5212 to form an electrical connection. After the power supply battery 5211 in the fixing seat 521 is powered up, the lower clamp seat 52 and the upper clamp seat 51 can be removed from the water-passing steel pipe 4 and placed in the charging cavity 64, and the charging plug 65 is plugged into the charging port 5212 for charging.

[0042] Furthermore, the outer shed wall 7 includes a number of hollow frames 71. A water collecting trough 72 is connected to the tops of the number of hollow frames 71. A filter screen 73 is installed inside the water collecting trough 72 for filtering out impurity particles in rainwater. A mounting plate 74 is connected to the bottoms of the number of hollow frames 71. A bottom plate 75 is arranged below the mounting plate 74. A steel bar 76 is connected to the bottom of the bottom plate 75. The bottom plate 75 is installed on the concrete on the ground surface by embedding the steel bar 76. A screw hole 77 is formed on the upper surface of the bottom plate 75. A mounting screw 78 is arranged through the mounting plate 74. The outer diameter of the mounting screw 78 is adapted to the inner diameter of the screw hole 77. Photovoltaic panels 79 are arranged on the outer sides of two adjacent hollow frames 71. A hinge seat 710 is connected between the outer side wall of the hollow frame 71 and the top of the photovoltaic panel 79. A second pin shaft 711 is arranged through the middle of the hinge seat 710. A cross beam 712 is vertically connected between two adjacent hollow frames 71 to maintain the stability of the installation of the hollow frame 71. An electric telescopic rod 713 is installed in the middle of the cross beam 712. A third pin shaft 714 is arranged through the two ends of the electric telescopic rod 713 between the cross beam 712 and the photovoltaic panel 79 respectively. The photovoltaic panel 79 is rotationally connected to the hollow frame 71 through the hinge seat 710 and the second pin shaft 711. The photovoltaic panel 79 is electrically connected to the photovoltaic storage battery 62. The two ends of the electric telescopic rod 713 are rotationally connected to the cross beam 712 and the photovoltaic panel 79 through the third pin shaft 714 respectively. During the day, the electric telescopic rod 713 extends, and the electric telescopic rod 713 pushes the photovoltaic panel 79 to rotate outward around the first pin shaft 57, so that a number of photovoltaic panels 79 expand relative to the greenhouse main body 2, making the photovoltaic panels 79 fully exposed to sunlight. At night, the electric telescopic rod 713 contracts to pull the photovoltaic panel 79 to fold up, and the photovoltaic panel 79 covers the gap between two adjacent hollow frames 71, forming a second layer of shed wall outside the greenhouse main body 2, achieving the effect of keeping the greenhouse warm at night and reducing heat dissipation. By installing the photovoltaic panels 79 on both sides of the greenhouse main body 2 instead of the traditional way of installing on the top of the greenhouse, during the day, the light shines directly from above the greenhouse main body 2, which can provide sufficient light intensity for the crops in the greenhouse main body 2 without the need for artificial additional lighting, saving the electric energy consumed by lighting. The equipment required for the photovoltaic panel 79 to convert electric energy can be installed in the gap between the photovoltaic panel 79 above the cross beam 712 and the greenhouse main body 2.

[0043] Furthermore, the hollow frame 71 is in the shape of a rectangular column with a hollow interior, and the inner cavities of several hollow frames 71 are connected to the water collecting trough 72. The left and right edges of the greenhouse main body 2 are clamped between the mounting plate 74 and the bottom plate 75. The mounting screws 78 penetrate the mounting plate 74, the greenhouse main body 2 and the screw holes 77 and are threadedly connected. The bottom plate 75 is pre-buried and installed with the concrete ground through the steel bars 76. The hollow frame 71 is not only used as the main support of the outer layer of the shed wall 7, but also for installing photovoltaic panels 79. It is also used to collect and divert rainwater, and directly collect and utilize rainwater to save water resources. The hollow frame 71 is installed on the bottom plate 75 through the mounting plate 74, which not only realizes the rapid installation of the hollow frame 71, but also can quickly clamp and seal the two sides of the greenhouse main body 2 to maintain the airtightness of the environment inside the greenhouse main body 2. In addition, the top of the hollow frame 71 can be connected to the skeleton 1 by passing the greenhouse main body 2 through the steel wire. The hollow frame 71 reinforces the side wall of the greenhouse main body 2 to enhance the wind and rollover resistance of the greenhouse main body 2.

[0044] Furthermore, the water storage mechanism 8 includes a water tank 81 installed on the inner wall of the frontmost frame 1, an inlet pipe 82 is connected between the water tank 81 and the hollow frame 71, a water pump 83 is installed on the upper surface of the water tank 81, a water outlet pipe 84 is connected between the water inlet of the water pump 83 and the water tank 81, and the water outlet of the water pump 83 is connected to a water supply network 85. Several hollow frames 71 are connected through the inlet pipe 82, and several hollow frames 71 are connected to the water tank 81 through the inlet pipe 82. The end of the water supply network 85 away from the water pump 83 is connected to the pipe joint 42 on the front side of the water-passing steel pipe 4. Rainwater is filtered through the filter screen 73 in the water collecting trough 72 and flows into the interior of several hollow frames 71, and finally flows into the water tank 81 from the inlet pipe 82, so as to reserve water resources for humidity adjustment of the environment inside the greenhouse main body 2 and save water resources.

[0045] The method of using this embodiment is as follows: when the user actually uses the greenhouse environment control system to adjust the environment in the greenhouse, the humidity sensor 63 first monitors the air humidity and soil humidity in the greenhouse body 2 in real time. When the humidity is high, the controller 61 starts the ventilation system in the greenhouse body 2 for ventilation and dehumidification. When the humidity is low, the humidity regulating mechanism 5 is started for humidification. At this time, the humidity regulating mechanism 5 is in the initial position on the water-passing steel pipe 4. The controller 61 inputs a signal to the microprocessor 5210. After receiving the signal from the controller 61, the microprocessor 5210 starts the micro push rod 526. The micro push rod 526 is extended and the insert tube 523 is pushed into the water outlet 43 through the movable block 525. The insert pipe 523 pushes the block 45 to move up and disengage from the slot 44. The block 45 drives the limit rod 46 to move up in the limit slot 47 and compress the spring 48, so that the inner cavity of the water-passing steel pipe 4 is connected with the insert pipe 523 through the water inlet slot 524. At the same time, the water pump 83 passes water into the water-passing steel pipe 4 through the water supply network 85. The water flow inside the water-passing steel pipe 4 flows from the insert pipe 523 into the bellows 527 and the fixed pipe 528, and finally sprays out from the nozzle 529 to increase the humidity of the environment in the greenhouse body 2. After the humidity adjustment in this area is completed, the micro push rod 526 contracts and pulls the insert pipe 523 to move down in the water outlet 43 and shrink into the movable slot 522. At this time, the block 45 loses the thrust of the insert pipe 523 and is driven by the rebound of the spring 48. The block 45 is inserted into the slot 44 to block the water outlet 43, and then the motor 514 drives the shaft 512 to rotate, and the shaft 512 drives the gear 511 to rotate. The gear 511 rotates in the tooth groove 41 to drive the upper clamp seat 51 and the lower clamp seat 52 to move relative to the water-passing steel pipe 4, and walks on the water-passing steel pipe 4 through the ball 54, and then repeats the above operation after walking a specified distance to adjust the humidity of other areas in turn, and perform single nozzle 529 walking type partition spraying. During the environmental humidity monitoring and humidity adjustment process in the greenhouse main body 2, the controller 61 controls the electric telescopic rod 713 to extend during the day, and the electric telescopic rod 713 pushes the photovoltaic panel 79 to rotate outward around the first pin 57, so that several photovoltaic panels 79 is extended relative to the greenhouse body 2, so that the photovoltaic panel 79 is fully exposed to the sunlight, converting solar energy into electrical energy and storing it in the photovoltaic battery 62, and the photovoltaic battery 62 supplies power to other electrical equipment in the control box 6 and the greenhouse body 2. At night, the electric telescopic rod 713 contracts and pulls the photovoltaic panel 79 together, and the photovoltaic panel 79 covers the gaps between adjacent hollow frames 71, forming a second layer of greenhouse wall on the outside of the greenhouse body 2, and keeping the greenhouse warm at night. In rainy weather, rainwater is filtered through the filter screen 73 in the water collection trough 72 and flows into the interior of several hollow frames 71, and finally flows into the water storage tank 81 from the water inlet pipe 82, so as to reserve water resources for humidity adjustment in the greenhouse body 2.
