Description

Technical Field

[0001] This invention relates to the field of agricultural greenhouse technology, specifically to a greenhouse microclimate intelligent sensing and adaptive control device. Background Technology

[0002] Agricultural greenhouses can effectively help keep plants warm and prevent damage caused by low temperatures. Some greenhouses have large interior spaces, so multiple sets of sensors are usually needed to better monitor the microclimate inside the greenhouse. These sensors detect different areas to achieve climate perception, and then make adaptive adjustments based on the situation.

[0003] For example, utility model CN216254227U discloses an automatic temperature-regulating multifunctional agricultural greenhouse, which facilitates shading when the outside sunlight is strong and watering of the plants grown inside the greenhouse. The greenhouse includes a main body, with a recovery shaft and a tension shaft rotatably connected to the top of the main body via a recovery plate and a tension plate, respectively. A rotating motor is installed on the recovery plate and the tension plate, and the rotating motor is fixedly connected to the recovery shaft and the tension shaft. A sunshade curtain is fitted onto the recovery shaft and wrapped around its circumference. Multiple traction ropes are connected to the tension shaft, and the other ends of the traction ropes are fixedly connected to the sunshade curtain. Two traveling rails are fixedly connected inside the main body of the greenhouse, and a spraying system is fixedly connected to each of the two traveling rails. Multiple air vents are opened at both the front and rear ends of the main body of the greenhouse, and a ventilation mechanism is fixedly connected to each air vent. An inlet and outlet are opened at the front end of the main body of the greenhouse.

[0004] Existing technologies can adaptively regulate the interior of greenhouses by setting up multiple sets of structures. However, setting up multiple sets of sensors to detect the interior space of the greenhouse not only increases the procurement cost of the sensors, but also increases the cost of power supply control and subsequent maintenance of the sensors. In addition, the interior space of the greenhouse is large, and the temperature difference caused by the uniformity of light and cloud cover results in the problem of the interior space. The detection range of a single temperature sensor is limited, and it is impossible to detect the temperature of a large area inside the greenhouse with a single temperature sensor, which increases the temperature detection cost of the device to a certain extent. CN216254227U relies on multiple sets of sensors, which increases the procurement, installation and maintenance costs, and the detection range is limited with blind spots. Multiple sets of drive motors increase the procurement, energy consumption and debugging costs, and the control logic is complex.

[0005] Therefore, there is an urgent need to develop a greenhouse microclimate intelligent sensing and adaptive control device to solve the problems in the existing technology. Summary of the Invention

[0006] The purpose of this invention is to provide a greenhouse microclimate intelligent sensing and adaptive control device, which can solve the problem that it is impossible to detect the temperature of a large area inside the greenhouse using a single set of temperature sensors, which increases the temperature detection cost of the device to a certain extent and also increases the driving cost, thereby solving the problems mentioned in the background art.

[0012] By adopting the above technical solution, a linkage opening component is provided in the middle of both sides of the two sets of greenhouse frames; The linkage opening component includes four sets of limiting plates. The limiting plates are fixedly installed on the inner side of the lower end of the greenhouse frame. A rotating sleeve is rotatably arranged between two sets of limiting plates. A push rod is slidably arranged on the inner side of the rotating sleeve. Arc-shaped guide plates are rotatably arranged on both sides of the lower end of the push rod. The arc-shaped guide plates are slidably arranged on the inner side of both ends of the greenhouse frame. A flip plate is fixedly installed on the end of the arc-shaped guide plate away from the push rod. The flip plate is arranged in the groove on the side of the greenhouse frame.

[0016] By adopting the above technical solution, a bearing frame is installed on the top of the support frame, and the prismatic sleeve is rotatably arranged inside the bearing frame.

[0017] Compared with the prior art, the beneficial effects of the present invention are: This invention, through the coordinated arrangement of a linkage adjustment component and a greenhouse frame, facilitates the adjustment of the temperature sensor component's position via a linkage mechanism, thereby enabling cross-range temperature detection within the greenhouse. A drive motor directly rotates the drive shaft and transmission prism, causing the adjusting gear to move along the inner side of the gear ring groove. During adjustment, the swing arm is controlled to rotate along the lower positioning plate, changing the position of the temperature sensor. An electric push rod controls the telescopic rod and drive motor to move upwards along the inner side of the swing arm, separating the transmission prism from the adjusting gear. After separation, it is embedded inside the prism sleeve for splicing. As the drive motor continues to rotate, the first and second helical gears drive the reverse lead screw to rotate and adjust. The screw thread controls the movement of the adjusting slider, thereby changing the spacing of the adjusting plates. Adjusting the spacing unfolds the shade net. This invention effectively reduces the use of drive motors, significantly lowering drive costs. A single motor can be used to change the position of the temperature sensor, enabling cross-range microclimate detection within the greenhouse. This effectively reduces device detection and drive costs. By using a single sensor combined with a single motor and electric actuator in a linkage adjustment assembly to replace multiple designs, procurement, energy consumption, and maintenance costs are significantly reduced. Cross-range sensor detection eliminates blind spots, resulting in more precise control and improved microclimate regulation efficiency. The linkage adjustment assembly of this invention, through a combination of a single drive motor and specific technical features such as transmission prisms and adjusting gears, achieves cross-range movement detection of the temperature sensor, thereby reducing the number of sensors and drive devices used, lowering costs. The swing rod and temperature sensor assembly flip when the adjusting gear moves, covering a larger area, achieving cross-range detection with a single sensor and solving the detection cost problem.

[0018] This invention, through the coordinated use of a linkage opening component and a linkage adjustment component, allows for the continuous control of the swing rod's rotation. The upper limit frame presses down on the push rod, and during this pressing process, the arc-shaped guide plate at the end of the push rod slides along the inner groove of the frame member. This sliding motion pushes two sets of rotating plates to rotate along the axis. During this rotation, the locking wedge, pushed by the return spring, extends outward and embeds into the groove at the top of the arc-shaped guide plate, achieving a locking effect. To unlock, the electric push rod controls the drive motor to move downward. During this downward movement, the pressing column and the adjusting rod work together to pull the connecting rope, which in turn pulls the pressing block upward, causing the locking wedge to move upward. After unlocking, the rotating plates automatically close under their own weight. This effectively reduces the use of a drive device, lowering costs, while allowing for flexible adjustment and unlocking, facilitating ventilation of the interior.

[0037] The working principle and usage process of this invention: When the drive motor 401 is powered on, it will drive the adjusting gear 300 to rotate along the inner side of the gear ring groove 101. During the rotation, it will drive the swing rod 305 to flip and adjust along the positioning plate 301. During the adjustment, the position of the temperature sensor 306 will be changed for intelligent sensing and detection. After the detection is completed, the electric push rod 302 will be used to drive the telescopic rod 304 to extend outward. When extending outward, the telescopic rod 304 will push the drive motor 401 to lift. During the lifting process, the transmission prism 400 will be inserted into the inner side of the prism sleeve 104 for splicing. Rotating again will drive the reverse screw 202 to adjust. By controlling the adjustment slider 203 to move laterally, the drive plate 205 can drive the adjustment plate 206 to adjust the spacing and change the position of the sunshade net 200. When the flip plate 500 needs to be opened, the swing rod 305 swings and controls the push rod 503 to extend outward through the upper limit frame 307. During the extension, the arc-shaped guide plate 504 will extend outward, and finally push the flip plate 500 to open. When unlocking is required, keep the swing rod 305 perpendicular to the ground, and use the electric push rod 302 to control the telescopic rod 304, drive motor 401 and pressure column 402 to move down. During the downward movement, contact with the adjustment rod 607 will squeeze the connecting rope 606 and the pressure block 605 at the end to move up, thereby causing the locking inclined block 600 to separate from the arc-shaped guide plate 504. Under its own weight, the flip plate 500 will automatically close.
