Description

Technical Field

[0001] This invention relates to the field of agricultural technology, specifically to an agricultural technology vegetable greenhouse with a flip-top and automatic watering system. Background Technology

[0002] As an important facility in modern agriculture, vegetable greenhouses provide suitable temperature, humidity, and light environments for vegetable growth, effectively extending the vegetable growing cycle and improving vegetable yield and quality. With the continuous development of agricultural technology, the automation and intelligence levels of vegetable greenhouses are gradually improving.

[0003] Currently, existing vegetable greenhouses typically employ fixed roofs or simple roller shutter structures. For example, existing technology discloses a vegetable greenhouse with an openable and closable roof (CN213427330U), which uses hydraulic telescopic rods to drive the first and second cover plates to rotate, thus opening and closing the roof. However, this type of rotating opening and closing mechanism is complex, requires a large amount of space for the cover plates to rotate, and is subject to significant stress in windy weather, posing a safety hazard. Furthermore, some greenhouses use sliding shading films to selectively open the roof, but their sliding mechanisms are often simple guide rails, lacking stable guiding and driving structures. After long-term use, problems such as jamming and poor sliding are prone to occur, and it is difficult to achieve smooth opening and closing of large areas of the roof.

[0004] In terms of irrigation, traditional vegetable greenhouses mostly rely on manual or timed watering, which cannot accurately irrigate according to the actual soil moisture, easily leading to problems of insufficient or excessive watering. Although some greenhouses have been equipped with sprinkler systems, most of them are fixed nozzles and lack linkage control with soil moisture monitoring, resulting in a low level of automation.

[0005] Regarding energy utilization, although some vegetable greenhouses have begun to use solar panels for power, these panels are mostly fixed installations and cannot be adaptively adjusted according to changes in the angle of sunlight, resulting in low solar energy utilization efficiency. Even in greenhouses equipped with adjustable-angle solar panels, the adjustment mechanisms are often complex and costly, making them difficult to promote and apply.

[0006] In addition, the existing vegetable greenhouses' roof opening and closing, irrigation, and ventilation functions are mostly independent, lacking a unified intelligent control system for coordinated management. This makes it impossible to achieve multi-functional linkage control based on changes in environmental parameters, and the level of intelligence needs to be improved.

[0007] In summary, existing vegetable greenhouses suffer from problems such as complex and unstable roof opening and closing mechanisms, reliance on manual or timed irrigation with a lack of precision, fixed solar panel angles leading to low energy efficiency, and a lack of intelligent linkage control among various functional modules. There is an urgent need for a vegetable greenhouse solution that is structurally sound, reliable in operation, and intelligent. Summary of the Invention

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Example 1 like Figures 1 to 10 As shown in the figure, an agricultural technology vegetable greenhouse with a flip-top automatic watering according to an embodiment of the present invention mainly includes a main body 1, a greenhouse roof device 2, an irrigation device 3, a solar energy regulating device 4, and a control box 5.

[0027] Main body 1 serves as the foundation support structure of the greenhouse, with an overall rectangular frame structure, constructed from welded or bolted steel or aluminum alloy profiles. Translucent covering materials (such as glass or plastic film) are installed on the four sides and end walls of main body 1 as needed to create an enclosed planting space. Main body 1 possesses sufficient structural strength and rigidity to support the roof assembly 2, irrigation system 3, solar energy regulation system 4, and other upper structures, as well as to resist external loads such as wind and snow. The top of main body 1 is an open structure for installing the roof assembly 2.

[0028] The roof device 2 is installed on the top of the main body 1 to enable the roof of the greenhouse to be opened and closed by flipping. The roof device 2 includes a supporting top frame 21, multiple sliding components 22, multiple sets of frames 23, a first drive component 24, and a canopy 25.

[0029] The supporting top frame 21 is fixedly installed on both sides of the top of the main body 1 along its length. The supporting top frame 21 consists of two parallel, horizontally extending steel rails, which can be made of I-beams or H-beams, with an "I" or "C" shaped cross-section, and have an upper flange, a lower flange, and a web connecting the upper and lower flanges. The upper flange of the supporting top frame 21 serves as the sliding rail for the first pulley group 222 of the sliding assembly 22, and the side wall of the supporting top frame 21 (i.e., the outer side of the web) serves as the sliding rail for the second pulley group 223 of the sliding assembly 22. The supporting top frame 21 is fixedly installed on the top longitudinal beam of the main body 1 by welding or bolting.

[0030] like Figure 5 , Figure 6 and Figure 7As shown, multiple sliding components 22 are slidably disposed at both ends of the support top frame 21. Specifically, multiple sliding components 22 are arranged along the length direction of the support top frame 21 on the left and right sides of the main body 1. The sliding components 22 on the left and right sides correspond one-to-one with each other at positions perpendicular to the length direction of the support top frame 21. Each sliding component 22 includes a sliding plate 221, a first pulley group 222, and a second pulley group 223. The sliding plate 221 is a vertically arranged rectangular metal plate, the surface of which is parallel to and opposite to the side wall of the support top frame 21. The sliding plate 221 is slidably disposed on the side wall of the support top frame 21. The first pulley group 222 is fixedly disposed on the inner top of the sliding plate 221, that is, near the upper flange of the support top frame 21. The first pulley assembly 222 includes at least two first pulleys, which are spaced apart along the length of the supporting top frame 21. The wheel surfaces of the first pulleys are in rolling contact with the upper surface of the upper flange of the supporting top frame 21, allowing the sliding plate 221 to be suspended on the supporting top frame 21 via the first pulley assembly 222 and to roll and slide along the length of the supporting top frame 21. The second pulley assembly 223 is fixedly disposed on the inner side wall of the sliding plate 221, i.e., near the web of the supporting top frame 21. The second pulley assembly 223 includes at least two second pulleys, which are spaced apart along the length of the supporting top frame 21. The wheel surfaces of the second pulleys are in rolling contact with the outer side of the web of the supporting top frame 21, allowing the sliding plate 221 to obtain lateral support and guidance on the side wall of the supporting top frame 21 via the second pulley assembly 223, preventing the sliding plate 221 from swaying or derailing during sliding. With the cooperation of the first pulley group 222 and the second pulley group 223, the sliding component 22 can slide smoothly and steadily along the support top frame 21 with low frictional resistance and low operating noise.

[0031] Multiple sets of frame 23 form an arched structure, each set made of curved metal tubing (such as galvanized steel pipe), the curvature of which matches the required profile of the greenhouse roof. These multiple sets of frame 23 are spaced apart along the length of the supporting roof frame 21, with both ends of each set connected to sliding components 22 located on the two sides of the supporting roof frame 21. Specifically, the left end of each set of frame 23 is fixedly connected (e.g., by welding or bolting) to a corresponding sliding plate 221 of the sliding component 22 on the left supporting roof frame 21, and the right end of each set of frame 23 is fixedly connected to a corresponding sliding plate 221 of the sliding component 22 on the right supporting roof frame 21. Thus, the multiple sets of frame 23 form an arched supporting frame for the greenhouse roof above the supporting roof frame 21.

[0032] The first drive assembly 24 is mounted on the support frame 21 and is used to drive the sliding assembly 22 to slide back and forth along the length of the support frame 21. Figure 5 and Figure 7As shown, the first drive assembly 24 includes two first drive motors 241, two first pulleys 242, two second pulleys 243, two belts 244, and two fixed connecting blocks 245. The two first drive motors 241 are respectively fixedly mounted on the outer side walls at both ends of the support top frame 21. The first drive motors 241 are preferably servo motors or stepper motors, with forward and reverse rotation functions and speed control functions to precisely control the sliding direction and speed of the sliding assembly 22. The two first pulleys 242 are respectively fixedly mounted on the output shafts of the two first drive motors 241 and rotate synchronously with the output shafts of the first drive motors 241. The two second pulleys 243 are rotatably mounted on the two end side walls of the support top frame 21, opposite to the first pulleys 242 on the same side. The second pulleys 243 are rotatably connected to the side walls of the support top frame 21 via bearings, serving as driven pulleys of the belts 244. Two belts 244 are respectively fitted between a first pulley 242 and a second pulley 243 located at the same end of the support top frame 21. The belts 244 mesh with the first pulley 242 and the second pulley 243 to form a closed belt drive circuit. Two fixed connecting blocks 245 are respectively fixedly installed on the first sliding plates 221 located at both ends of the support top frame 21, and the two fixed connecting blocks 245 are respectively fixedly connected to the ends of the two belts 244. Specifically, the fixed connecting blocks 245 are clamped and fixed at a certain position on the belts 244. When the belts 244 move under the drive of the drive motor, the fixed connecting blocks 245 move synchronously with the belts 244, thereby driving the first sliding plate 221 fixedly connected to the fixed connecting block 245 to slide along the support top frame 21. When the first sliding plate 221 moves, the first set of skeletons 23 connected to it pulls the second set of skeletons 23 adjacent to it, the second set of skeletons 23 pulls the third set of skeletons 23, and so on, thereby realizing the synchronous sliding of all sliding components 22.

[0033] The tarpaulin 25 is a waterproof and UV-resistant flexible covering material, such as PVC-coated fabric or PE woven fabric. The tarpaulin 25 covers the outer surface of multiple sets of frames 23, forming a shading and insulation layer for the greenhouse roof. One end of the tarpaulin 25 is fixed to one end of the supporting top frame 21 (e.g., by a pressure strip or clamp to the right end of the supporting top frame 21), and the other end of the tarpaulin 25 is fixedly connected to a set of frames 23 located at the leftmost end of the supporting top frame 21. When the first drive assembly 24 drives the sliding assembly 22 to slide to the right, the multiple sets of frames 23 move to the right and gradually converge, causing the tarpaulin 25 to fold and close to the right, gradually opening the greenhouse roof and achieving a "flip-top" effect. When the first drive assembly 24 drives the sliding assembly 22 to slide to the left, the multiple sets of frames 23 move to the left and gradually separate, causing the tarpaulin 25 to unfold and flatten to the left, gradually covering the greenhouse roof and achieving a "closing" effect. By controlling the forward and reverse rotation of the first drive motor 241, the automatic opening and closing of the greenhouse roof device 2 can be achieved.

[0034] The irrigation device 3 includes an irrigation assembly 31 disposed on the top of the main body 1. For example... Figure 4 As shown, the irrigation assembly 31 includes a water pump 311, a water pipe 312, and multiple sprinkler heads 313. The water pump 311 is fixedly installed on the side wall of the main body 1. The inlet of the water pump 311 is connected to an external water source (such as a reservoir, well, or municipal water supply network) via a pipe, and the outlet of the water pump 311 is connected to the water pipe 312. The water pump 311 is an electric water pump, and its start and stop are controlled by the control box 5. The water pipe 312 is laid along the top longitudinal beam of the main body 1, horizontally positioned below the top inner wall of the main body 1, below the frame 23. The water pipe 312 is made of PVC pipe or galvanized steel pipe and extends along the length of the main body 1. Multiple sprinkler heads 313 are arranged on the water pipe 312, spaced apart along the length of the water pipe 312. The inlet end of each sprinkler head 313 is threaded or bonded to the water pipe 312, and the spray nozzle of the sprinkler head 313 faces downwards towards the planting area inside the greenhouse. The sprinkler head 313 is an atomizing or rotating nozzle that can evenly spray water onto the vegetable crops below.

[0035] The solar energy regulation device 4 includes an adjustment component 41 disposed on the main body 1, which is used to adjust the tilt angle of the solar panel 413. Figure 8As shown, the adjustment assembly 41 includes a support frame 411, a rotating rod 412, a solar panel 413, a first sprocket 414, a second drive motor 415, a second sprocket 416, and a chain 417. The support frame 411 is fixedly installed on one side of the top of the main body 1. The support frame 411 is a triangular bracket, welded from metal profiles, and has sufficient structural strength. The rotating rod 412 is rotatably mounted on the support frame 411 via bearings. The rotating rod 412 extends horizontally along the length of the main body 1, and both ends of the rotating rod 412 are rotatably connected to the support frame 411 via rolling bearings, allowing the rotating rod 412 to rotate freely around its own axis. The solar panel 413 is a flat photovoltaic panel, and its back is fixedly mounted on the rotating rod 412 with bolts. The surface of the solar panel 413 changes its tilt angle as the rotating rod 412 rotates. The first sprocket 414 is fixedly mounted on one side of the shaft end of the rotating rod 412. The first sprocket 414 and the rotating rod 412 are connected by a key or fixed by a set screw, and rotate synchronously with the rotating rod 412. The second drive motor 415 is fixedly mounted on the support frame 411. The second drive motor 415 is preferably a servo motor or a stepper motor, with forward and reverse rotation functions and precise angle control functions. The second sprocket 416 is fixedly mounted on the output shaft of the second drive motor 415 and rotates synchronously with the output shaft of the second drive motor 415. The chain 417 is meshed between the first sprocket 414 and the second sprocket 416 to form a sprocket and chain transmission mechanism. When the second drive motor 415 is started, the second sprocket 416 rotates and drives the first sprocket 414 to rotate through the chain 417. The first sprocket 414 drives the rotating rod 412 to rotate, thereby precisely adjusting the tilt angle of the solar panel 413.

[0036] The control box 5 is located on the side wall of the main body 1. The control box 5 is a closed electrical control cabinet, containing a programmable logic controller (PLC) or microcontroller control board, relays, AC contactors, power modules, and other electrical components. The control box 5 is electrically connected to the first drive assembly 24 (i.e., two first drive motors 241) of the roof device 2, the water pump 311 of the irrigation device 3, and the second drive motor 415 of the solar energy regulating device 4. The control box 5 supplies power to the aforementioned electrical equipment via cables and sends control commands, achieving centralized control of the roof opening and closing, irrigation start and stop, and solar panel angle adjustment. The control box 5 can also be equipped with a display screen and control buttons on its panel for easy on-site operation and parameter setting.

[0037] In addition, the vegetable greenhouse in this embodiment also includes a light intensity sensor 6 and a soil moisture sensor 7. The light intensity sensor 6 is located on the exterior of the main body 1, fixedly installed on the top outer wall of the main body 1, with its photosensitive surface facing upwards, and is used to detect ambient light intensity. The light intensity sensor 6 is electrically connected to the control box 5, converting the detected ambient light intensity into an electrical signal (i.e., a light signal) and sending it to the control box 5. The soil moisture sensor 7 is buried in the planting soil inside the main body 1, with its probe inserted into the soil at a suitable depth (usually 10 cm to 20 cm), and is used to detect the volumetric water content of the soil. The soil moisture sensor 7 is electrically connected to the control box 5, converting the detected soil moisture into an electrical signal (i.e., a moisture signal) and sending it to the control box 5. Multiple soil moisture sensors 7 can be buried in different areas inside the main body 1 to comprehensively monitor the soil moisture status at different locations within the greenhouse, using the average or lowest value as the control basis. The control board inside the control box 5 processes and judges the signals sent by the light intensity sensor 6 and the soil moisture sensor 7 according to the preset control logic, and controls the start and stop of the first drive component 24 and the irrigation device 3 accordingly.

[0038] The following describes in detail the complete working process of the agricultural technology vegetable greenhouse with flip-top automatic watering in this embodiment.

[0039] During vegetable cultivation, the light intensity sensor 6 detects the ambient light intensity in real time and sends the light signal to the control box 5. The control box 5 has preset upper and lower threshold values ​​for light intensity. When the ambient light intensity exceeds the preset upper threshold (for example, excessive midday sunlight in summer may scorch the vegetables), the control box 5 determines that shading is needed and then controls the two first drive motors 241 to start forward. The first drive motor 241 drives the first pulley 242 to rotate, and the first pulley 242 drives the second pulley 243 to rotate via the belt 244. During the movement, the belt 244 drives the fixed connecting block 245 to move in the unfolding direction (i.e., the direction in which the tarpaulin 25 unfolds). The fixed connecting block 245 drives the first sliding plate 221, which is fixedly connected to it, to slide along the supporting top frame 21. The first sliding plate 221 drives all subsequent sliding components 22 to move synchronously through the first set of frame 23 connected to it. As the multiple sets of frames 23 gradually separate, the tarpaulin 25, supported by the frames 23, gradually unfolds and eventually completely covers the top of the greenhouse, providing shade for the interior. When the ambient light intensity drops below a preset lower threshold (e.g., in the evening or on a cloudy day with insufficient sunlight), the control box 5 determines that increased lighting is needed and immediately controls the two first drive motors 241 to start in reverse. The first drive motors 241 reverse, driving the sliding component 22 to slide in reverse through the aforementioned transmission path. The multiple sets of frames 23 gradually close and retract, and the tarpaulin 25 folds and retracts, opening the top of the greenhouse and allowing natural light to enter the interior.

[0040] Meanwhile, the soil moisture sensor 7 detects the soil moisture in real time and sends the moisture signal to the control box 5. The control box 5 has preset lower and upper soil moisture thresholds. When the soil moisture falls below the preset lower threshold (indicating the soil is too dry and needs watering), the control box 5 starts the water pump 311. The water pump 311 pressurizes water from an external source and sends it into the water pipe 312. The water flows along the water pipe 312 to each sprinkler head 313, where it is atomized or sprayed evenly onto the vegetable crops and soil surface, achieving automatic irrigation. During irrigation, the soil moisture sensor 7 continuously monitors the soil moisture. When the soil moisture rises and reaches the preset upper threshold, the control box 5 stops the water pump 311, stopping irrigation and maintaining the soil moisture within a suitable range for vegetable growth.

[0041] Simultaneously, the control box 5 periodically starts the second drive motor 415 of the solar energy regulating device 4 according to a preset time period or based on the light intensity detected by the light intensity sensor 6. The second drive motor 415 drives the second sprocket 416 to rotate, which in turn drives the first sprocket 414 to rotate via a chain 417. The first sprocket 414 then drives the rotating rod 412 to rotate, which in turn drives the solar panel 413 fixed thereon to rotate synchronously, thereby changing the tilt angle of the solar panel 413. The control box 5 controls the rotation direction and angle of the second drive motor 415 according to the daily or seasonal variation of the solar altitude angle, ensuring that the surface of the solar panel 413 is always approximately perpendicular to the direction of sunlight, maximizing the absorption of solar energy and converting it into electrical energy for use by the equipment in the greenhouse or for storage in the battery. When the solar panel 413 rotates to the target angle, the control box 5 stops the second drive motor 415, maintaining the current angle until the next adjustment.

[0042] Through the above working process, this embodiment realizes intelligent linkage control of automatic roof flipping, automatic irrigation, and automatic angle adjustment of the solar panels in the vegetable greenhouse.

[0043] Example 2 This embodiment is basically the same as embodiment 1 in structure and working principle, except that: multiple electric exhaust fans 11 are provided on both sides of the main body 1 in this embodiment.

[0044] Multiple electric exhaust fans 11 are respectively embedded in the openings on both sides of the main body 1, arranged at intervals along the length of the main body 1. Each electric exhaust fan 11 is an axial flow exhaust fan, including fan blades, a drive motor, and a protective mesh cover. The drive motor of the electric exhaust fan 11 is electrically connected to the control box 5 and is controlled by the control box 5 to start or stop. The control box 5 is also connected to a temperature sensor, which is located inside the main body 1, to detect the air temperature inside the greenhouse and send the temperature signal to the control box 5. When the temperature inside the greenhouse exceeds a preset upper temperature threshold, the control box 5 controls the electric exhaust fans 11 to start, expelling the hot and humid air inside the greenhouse. Simultaneously, fresh air from outside enters the greenhouse through the vents or gaps in the main body 1, achieving forced ventilation and cooling. When the temperature inside the greenhouse drops below a preset lower temperature threshold, the control box 5 controls the electric exhaust fans 11 to stop, reducing heat loss. By setting up electric exhaust fans 11, this embodiment achieves automatic temperature regulation inside the greenhouse, providing more suitable environmental conditions for vegetable growth. The remaining structure and working principle are exactly the same as in Example 1, and will not be repeated here.

[0045] Example 3 The structure and working principle of this embodiment are basically the same as those of embodiment 1, except that the top edge of the main body 1 in this embodiment is provided with a waterproof edge.

[0046] The waterproof edge is a raised, folded edge continuously running along the top edge of the main body 1, formed by bending metal sheets or laying waterproof roll material. The waterproof edge is 5 to 15 centimeters high and extends continuously along the top edges of the main body 1, forming a closed enclosure structure. When the tarpaulin 25 is unfolded and covers the top of the greenhouse, its edges naturally droop and overlap the outside of the waterproof edge; that is, the edges of the tarpaulin 25 are on the outer surface of the waterproof edge, and the waterproof edge is on the inner side of the edges of the tarpaulin 25. In rainy weather, rainwater falls on the upper surface of the tarpaulin 25 and flows along its surface towards the edges. At the edges of the tarpaulin 25, rainwater flows downwards along the outer surface of the tarpaulin 25. Because the edges of the tarpaulin 25 overlap the outside of the waterproof edge, the waterproof edge prevents rainwater from seeping into the greenhouse along the inner surface of the tarpaulin 25, thus providing an effective waterproof seal. By incorporating waterproof edges, this embodiment provides excellent waterproofing when the greenhouse roof is closed, ensuring its airtightness during rainy weather and preventing rainwater intrusion that could adversely affect vegetable growth. The remaining structure and working principle are identical to those of Embodiment 1 and will not be repeated here.

[0047] It should be noted that the control method in the embodiments of this application can be automatically controlled by a controller. The control method of the controller can be implemented by simple programming by those skilled in the art, which is common knowledge in the field. Furthermore, this application is mainly used to protect mechanical structures, so the control method and circuit connection will not be explained in detail here.

[0048] The technical solutions in the above-described embodiments of this application achieve smooth and automatic flipping of the tarpaulin 25 through the roof device 2 composed of the supporting top frame 21, sliding component 22, frame 23, and first drive component 24; the linkage between the soil moisture sensor 7 and the control box 5 controls the start and stop of the water pump 311, achieving precise irrigation on demand and avoiding water waste; the second drive motor 415 and the sprocket and chain mechanism drive the rotating rod 412 to adjust the angle of the solar panel 413, improving the efficiency of solar energy utilization; at the same time, the cooperation between the light intensity sensor 6 and the control box 5 achieves intelligent linkage between the opening and closing of the roof and the light intensity, effectively improving the level of automation control of the greenhouse.

[0049] Obviously, the above-described embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention also intends to include these modifications and variations.
