Description

Technical Field

[0001] The present invention relates to the technical field of greenhouses, and more specifically, to a humidity detection device based on agricultural greenhouse planting. Background Art

[0002] Agricultural greenhouse planting is a modern agricultural planting technology. By using special materials and structures, a controllable microclimate is created in an open-air planting environment to meet the needs of plant growth. This technology can transmit light, keep warm (or heat), provide a greenhouse growth period and increase yields. It is mostly used for the cultivation or seedling raising of thermophilic vegetables, flowers, trees and other plants in low temperature seasons. When planting in agricultural greenhouses, a humidity detection device is needed to detect the humidity in the greenhouse to avoid the impact of too high or too low humidity on the crops. However, the existing humidity detection device has the following shortcomings when detecting the humidity in the greenhouse: the humidity detection device is fixedly installed at a certain position in the greenhouse, and the humidity in the greenhouse can only be detected by the air carrying moisture flowing around the humidity detection device and contacting the humidity sensor inside the device. However, the space inside the greenhouse is large, and the humidity at two positions far apart is different. It is difficult for the fixed humidity detection device to accurately detect the air humidity at each position, reducing the comprehensiveness of the humidity detection in the greenhouse. Summary of the invention

The worm and the guide column are mounted at a vertical angle to the support connecting rod, and the worm and the guide column are mounted horizontally to the rear end of the air guide mechanism. The telescopic hose has a pleated structure and is made of rubber material. It has good resilience and can be elastically extended and contracted.

[0005] As a further improvement of the present invention, the air guide mechanism includes an air intake hood, an air guide pipe, and a guide vane. The middle portion of the upper end of the air intake hood is fixedly installed below the front end of the air guide pipe and is connected through it. A guide vane is welded to the inner wall of the upper end of the air guide pipe. The rear end of the air guide pipe is fixed to the front end of the telescopic hose and is connected through it. The air guide pipe is a 90-degree bent pipe, and five groups of guide vanes are welded on the inner wall of the upper end. Each group of guide vanes is provided with two, and are symmetrically installed inside the air guide pipe in an upper and lower manner.

[0006] As a further improvement of the present invention, the air intake hood includes a hood body, a filter, a pull ball, a baffle, and a torsion shaft. The middle part of the upper end of the hood body is fixedly installed below the front end of the air guide pipe and is connected through it. A filter is clamped and installed at the lower end of the interior of the hood body. A pull ball is provided at the middle end of the bottom of the filter. The outer end of the baffle is hinged to the inner wall of the lower end of the hood body through the torsion shaft, and the upper end surface of the baffle is in conflict with the bottom edge of the filter. Four baffles are provided, and both ends of each baffle are hinged to the inner wall of the lower end of the hood body through a torsion shaft, and elastic force is applied to the baffle through the torsion shaft.

[0007] As a further improvement of the present invention, the detection box includes a chassis, an air intake pipe, a detector, a bracket, and an exhaust pipe. The upper end of the chassis is provided with an air intake pipe, and the interior of the detector is connected to the air intake pump through the air intake pipe.

[0008] As a further improvement of the present invention, the detector includes a humidity detector, a transmitter, an exhaust fan, and a one-way opening and closing hole. The interior of the humidity detector is connected to the air intake pump through an air intake pipe. A transmitter is installed on the outer side of the lower end of the humidity detector, and the humidity detector is electrically connected to the display screen through the transmitter.

[0009] The beneficial effects of the present invention are: 1. The air intake pump generates negative pressure, so that the air inside the greenhouse is sucked in from the inside of the air intake hood. During the inhalation process, the torsion shaft applies elastic force to the baffle, so that the baffle can maintain a horizontal angle to clamp the filter at the lower end of the hood without being subjected to other external forces. The filter filters the dust and impurities in the air to prevent the air from carrying too much dust into the detection box and affecting the accuracy of the detection box's detection of air humidity. At the same time, the baffle rotates downward to facilitate the removal of the filter for replacement and cleaning; 2. When the air enters the upper end of the air guide pipe, the five groups of guide plates can guide the air backwards to speed up the air entering the detection box, avoiding the air humidity being affected during air intake, which may cause errors in the humidity detection data. In the process of air intake, the reduction motor is started to drive the worm to rotate, driving the air guide mechanism to move forward and backward for adjustment. The four suction mechanisms can intake air from four directions inside the greenhouse, avoiding air intake from a single direction, and improving the comprehensiveness of air humidity detection inside the greenhouse. 3. The four air suction mechanisms can be used to inhale air from four directions inside the greenhouse. The inhaled air is discharged into four humidity detectors through four air intake pipes. The four humidity detectors can synchronously detect the air humidity in four directions. During the detection process, the detected data is transmitted to the display screen through four transmitters for display, thereby synchronously detecting and displaying the air humidity in four directions, thereby improving the effect of detecting the air humidity in different positions; 4. After the air enters the humidity detector, it is sealed and connected through four silicone sheets set inside the one-way opening and closing hole set at the upper end of the exhaust fan connected to the bottom, so that the air can stay inside the humidity detector after entering it, avoiding insufficient residence time of the air inside the humidity detector and reducing the accuracy of air humidity detection.

The air intake mechanism J is installed at the middle end of the top of the detection box X and is through-connected. The air intake mechanism J includes a controller j5, an air intake pump j7, a connecting shell j2, and an air suction mechanism j9. The controller j5 is fixedly installed at the top of the connecting shell j2, and the controller j5 is electrically connected to the air intake pump j7. The air intake pump j7 is fixedly installed inside the connecting shell j2, and the air intake pump j7 is through-connected to the inner side end of the air suction mechanism j9. The air suction mechanism j9 is installed on the outer surface of the connecting shell j2, and the connecting shell j2 is installed at the middle end of the top of the detection box X, and the air intake pump j7 is through-connected to the inside of the detection box X. The controller j5, air intake pump j7, and air suction mechanism j9 are each provided in four numbers and are arranged at four positions of the connecting shell j2. The four air suction mechanisms j9 can intake air from four positions inside the greenhouse, avoiding air intake from a single position and improving the comprehensiveness of air humidity detection inside the greenhouse.

[0020] The air suction mechanism j9 includes a housing j97, a reduction motor j93, a worm j91, a sliding block j99, a guide column j96, a supporting connecting rod j95, a telescopic hose j94, and an air guide mechanism j92. The housing j97 is fixedly mounted on the outer surface of the connecting housing j2. A reduction motor j93 is installed inside the housing j97. The output end of the reduction motor j93 is welded to the worm j91 and rotates synchronously. The worm j91 is inserted into the sliding block j99 with clearance fit and is threadedly connected. The sliding block j99 is slidably mounted. Inside the upper end of the casing j97, the guide column j96 is fixedly installed inside the casing j97, and the guide column j96 is passed through the inside of the sliding block j99 by a clearance fit, the upper end of the sliding block j99 is welded to the bottom of the supporting connecting rod j95, and the upper end of the supporting connecting rod j95 is fixed to the rear end of the air guide mechanism j92, the rear end of the air guide mechanism j92 is fixed to the front end of the telescopic hose j94 and is connected in a through connection, the rear end of the telescopic hose j94 is fixedly installed on the outer surface of the connecting shell j2, and the rear end of the telescopic hose j94 is connected in a through connection with the intake pump j7; The worm j91 and the guide column j96 are installed at a vertical angle to the supporting connecting rod j95, and the worm j91 and the guide column j96 are installed in a horizontal position with the rear end of the air guide mechanism j92, so that when the reduction motor j93 drives the worm j91 to rotate, it drives the air guide mechanism j92 to move forward and backward under the support of the supporting connecting rod j95, thereby increasing the range of air suction in the greenhouse. The telescopic hose j94 has a pleated structure and is made of rubber material. It has good resilience and can be elastically extended and contracted, so that during the process of the air guide mechanism j92 moving forward and backward, the telescopic hose j94 can be tightly connected between the air intake pump j7 and the air guide mechanism j92 for a through connection.

[0021] The air guide mechanism j92 includes an air intake hood 2z, an air guide pipe 2g, and a guide plate 2t. The middle part of the upper end of the air intake hood 2z is fixedly installed below the front end of the air guide pipe 2g and is connected through. The inner wall of the upper end of the air guide pipe 2g is welded with a guide plate 2t. The rear end of the air guide pipe 2g is fixed to the front end of the telescopic hose j94 and is connected through. The air guide pipe 2g is a 90-degree bent pipe, and five groups of guide plates 2t are welded on the inner wall of the upper end. Each group of guide plates 2t is provided with two, and are symmetrically installed inside the air guide pipe 2g. The five groups of guide plates 2t can guide the air to flow backward, speed up the speed of air entering the detection box X, and avoid the air humidity being affected during air intake, which leads to errors in the humidity detection data.

[0022] The air inlet cover 2z includes a cover body z5, a filter screen z3, a pull ball z6, a baffle z1, and a torsion shaft z8. The middle part of the upper end of the cover body z5 is fixedly installed below the front end of the air guide pipe 2g and is connected through it. The filter screen z3 is clamped and installed at the lower end of the cover body z5. The middle end of the bottom of the filter screen z3 is provided with a pull ball z6. The outer end of the baffle z1 is hinged to the inner wall of the lower end of the cover body z5 through the torsion shaft z8, and the upper end surface of the baffle z1 is in conflict with the bottom edge of the filter screen z3. There are four baffles z1, and both ends of each baffle z1 are hinged to the inner wall of the lower end of the cover body z5 through a torsion shaft z8. The torsion shaft z8 applies elastic force to the baffle z1, so that the baffle z1 can maintain a horizontal angle to clamp the filter z3 at the lower end of the cover body z5 when not subject to other external forces, and filter the air during the air intake process to prevent the air from carrying more dust into the detection box X and affecting the accuracy of the detection box X in detecting the air humidity. The specific usage and function of this embodiment are as follows: In the present invention, when the air humidity inside the agricultural greenhouse is detected, the support bottom plate D is placed at the central position inside the greenhouse, and the air intake pump j7 is controlled by the controller j5 to operate. The air intake pump j7 generates negative pressure through the operation, so that the air inside the greenhouse is sucked in from the inside of the air intake cover 2z. During the inhalation process, the torsion shaft z8 applies elastic force to the baffle z1, so that the baffle z1 can maintain a horizontal angle to clamp the filter screen z3 at the lower end of the cover body z5 without being subjected to other external forces. The dust impurities in the air are filtered through the filter screen z3 to prevent the air from carrying more dust into the detection box X and affecting the accuracy of the detection box X in detecting the air humidity. At the same time, the baffle z1 rotates downward to facilitate the removal of the filter screen z3 for replacement and cleaning. Then, when the air enters the upper end of the air guide pipe 2g, it passes through the five groups of guide plates 2 t can guide the air flow backwards, speed up the speed of air entering the detection box X, avoid the air humidity being affected during air intake, and cause errors in the humidity detection data, and in the process of air intake, start the reduction motor j93 to drive the worm j91 to rotate, and drive the air guide mechanism j92 to move forward and backward under the support of the supporting connecting rod j95, so as to increase the range of air suction in the greenhouse. During the adjustment process, the telescopic hose j94 is elastically extended and contracted, so that during the process of the air guide mechanism j92 moving forward and backward, the telescopic hose j94 can be tightly connected between the air intake pump j7 and the air guide mechanism j92 for through connection. Through the four suction mechanisms j9, the air in four directions inside the greenhouse can be inhaled, avoiding the air intake work in a single direction, and improving the comprehensiveness of the air humidity detection inside the greenhouse.

Four one-way opening and closing holes x58 are provided inside the upper end of the exhaust fan x51, and each one-way opening and closing hole x58 is opened and closed by four silicone sheets, so that the air can stay after entering the humidity detector x54, thereby avoiding that the air does not stay in the humidity detector x54 enough to reduce the accuracy of air humidity detection. The specific usage and function of this embodiment are as follows: In the present invention, four air suction mechanisms j9 can be used to intake air at four directions inside the greenhouse, and the inhaled air is discharged into four humidity detectors x54 through four air intake pipes x3. The air humidity at four directions is synchronously detected by the four humidity detectors x54. During the detection process, the detected data is transmitted to the display screen S through four transmitters x56 for display, thereby synchronously detecting and displaying the air humidity at four directions, improving the effect of detecting the air humidity at different positions. After the air enters the humidity detector x54, it is sealed and connected with four silicone sheets arranged inside the one-way opening and closing hole x58 arranged at the upper end of the exhaust machine x51 connected to the bottom, so that the air can stay after entering the humidity detector x54, avoiding that the air stays in the humidity detector x54 for insufficient time and reduces the accuracy of air humidity detection. After the detection is completed, the exhaust machine x51 is started to generate suction, so that the four silicone sheets inside the one-way opening and closing hole x58 rotate downward, thereby discharging the air detected in the humidity detector x54, and then the subsequent air is detected.
