[0002] Every piece of land in a region (such as farmland, greenhouse, etc.) is affected by the climatic conditions of the region. At the same time, due to the different properties of the underlying surface, different thermal conditions and the influence of human activities, unique small-scale climates will be formed. The temperature, humidity, light and ventilation conditions in these microclimates directly affect the growth of crops and the working environment of humans. Therefore, it is necessary to monitor the microclimate environment so that adjustments can be made in real time.

[0003] Existing microclimate environment monitoring equipment usually installs a louver box on a bracket, and integrates various sensors such as temperature and humidity sensors, carbon dioxide sensors, PM2.5 sensors, atmospheric pressure sensors, etc. inside the louver box to monitor various factors in the microclimate environment through these sensors.

[0004] However, the installation height of the shutter box is fixed, and it can only monitor the air layer environment at the corresponding height. Since the environmental factors at different heights in the air will also be different, this will lead to the singleness of the monitoring. Moreover, since these monitoring sensors are outdoors for a long time, dust particles in the atmosphere will enter the shutter box and adhere to the outside of these sensors, which will affect the accuracy of the sensor detection data. In order to solve the above problems, it is necessary to develop a microclimate environment detection device that can be raised and lowered. Summary of the invention

[0005] The purpose of the present invention is to provide a microclimate environment monitoring device to solve the problem that the existing microclimate environment monitoring equipment has a single monitoring function, dust particles in the atmosphere enter the shutter box and adhere to the outside of the sensor, affecting the accuracy of the sensor detection data.

[0008] In some embodiments, a piston plate is connected to the top of the slide plate, and a sliding seal is formed between the piston plate and the inner wall of the outer tube. An air cavity is formed inside the outer tube above the piston plate. A one-way air outlet valve is installed in the middle of the piston plate, and a one-way air inlet valve is installed on the top of the outer tube. The position of the one-way air inlet valve corresponds to the position of the one-way air outlet valve up and down.

[0009] In some embodiments, a slide groove is provided on the inner side of the outer cylinder, and a sliding block cooperating with the slide groove is provided on the sliding plate and the piston plate.

[0026] The present invention will be further described in detail below in conjunction with the embodiments.

[0027] refer to Figures 1 to 9 The present invention provides a microclimate environment monitoring device, comprising a base 1, a lifting mechanism, an outer cylinder 6, two rotating frames 17, a monitoring head 15 and a bottom cover 10. A lifting mechanism is installed on the top of the base 1, and the outer cylinder 6 is sleeved on the lifting mechanism. The lifting mechanism can drive the outer cylinder 6, the two rotating frames 17, the monitoring head 15 and the bottom cover 10 to rise and fall within its height range, so that the microclimate environment of different height air layers within this range can be monitored.

[0028] The lifting mechanism includes a slide bar 3 and a screw rod 2 connected at the top of the base 1. The slide bar 3 is fixedly connected to the base 1. A motor 5 for driving the screw rod 2 to rotate is installed inside the base 1. The screw rod 2 is rotatably connected to the motor 5. An outer cylinder 6 is arranged between the slide bar 3 and the screw rod 2. A threaded sleeve 7 and a sliding sleeve 8 are respectively arranged on both sides of the outer cylinder 6 to cooperate with the screw rod 2 and the slide bar 3. The motor 5 is electrically connected to an external power supply. The motor 5 drives the screw rod 2 to rotate forward and reverse. The screw rod 2 cooperates with the threaded sleeve 7. The sliding sleeve 8 slides up and down on the outside of the slide bar 3, thereby driving the outer cylinder 6 to lift and lower, thereby realizing the lifting and lowering of the monitoring head. The top of the screw rod 2 and the slide bar 3 are connected to the top plate 4 to ensure the stability of the installation of the screw rod 2 and the slide bar 3.

[0029] The inner wall of the outer cylinder 6 is provided with a set of symmetrically arranged sliding structures, which include a slide plate 12, two racks 9 and two gears 13. Four racks 9 are respectively installed on both sides of the inner wall of the outer cylinder 6. The bottom end of the rack 9 is fixedly connected to the bottom cover 10. Tooth paths are provided on both sides of the two slide plates 12, and four gears 13 are respectively located between the four groups of tooth paths and the racks 9, and are rotatably connected with the corresponding racks 9 and tooth paths. The tooth paths of the racks 9 and the slide plates 12 are meshed with the gears 13, so that the two slide plates 12 are respectively slidably connected with the inner wall of the outer cylinder 6. The two slide plates 12 are respectively provided with two guide grooves 14, and the middle part of the guide groove 14 is a curved structure. Two rotating frames 17 are symmetrically arranged between the two slide plates 12. The outer side of the rotating frame 17 is provided with a limit groove 19 and a guide column 18, and the limit groove 19 is located above the guide column 18. A movable groove 21 is provided at the bottom end of the inner side of the outer cylinder 6. The guide column 18 slides in the guide groove 14 and the movable groove 21. A limiting column 20 is provided at the curved structure of the guide slot 19, and the limiting column 20 slides along the limiting slot 19 to limit the rotation frame 17. Both ends of the monitoring head 15 are connected to one end of the two rotation frames 17 close to the guide column 18 respectively.

[0030] The monitoring head 15 is a template with various sensors integrated on one side, including temperature and humidity sensors, carbon dioxide sensors, PM2.5 sensors, atmospheric pressure sensors and other environmental monitoring related sensors. The above sensors are used to monitor various factors in the microclimate environment, such as Figure 2 , Figure 6 , Figure 7 as well as Figure 8 , the sensor on the monitoring head 15 is facing downward and exposed to the outside, in a normal monitoring working state. In this state, the bottom cover 10 and the outer tube 6 are in a separated state, the rack 9 is pulled out, and the slide plate 12 is located inside the outer tube 6. When the lifting mechanism drives the outer tube 6 to descend to the lowest point, the bottom cover 10 first abuts against the top of the base 1, and then the outer tube 6 continues to press downward, the rack 9 will shrink into the upper space, and the rack 9 drives the slide plate 12 to move downward through the gear 13. In this process, the guide column 18 slides in the guide groove 14, and the limit column 20 slides in the limit groove 19. When the limit column 20 slides to the bottom position of the limit groove 19 and is abutted, the guide column 18 slides to the position below the curved structure of the guide groove 14, and then the slide plate 12 continues to move downward. During the process, the guide column 18 is guided by the curved structure of the guide groove 14 to move sideways and then return to its original position. The movable groove 21 provides a movable space for the lateral movement of the guide column 18. At this time, the rotating frame 17 will be turned over with the support of the guide column 18 with the limiting column 20 as the axis, so that the sensor side of the monitoring head 15 will be turned over upward. After the rotating frame 17 is turned over, the slide plate 12 will continue to move a distance under the guidance of the upper guide groove 14, so that the monitoring head 15 is stored in the space inside the outer tube 6. At this time, the outer tube 6 and the bottom cover 10 are closed. Figure 1 As shown, this state can protect the monitoring head and can be maintained when not in use.

[0031] Furthermore, in this embodiment, a piston plate 16 is connected to the top of the slide plate 12, and the piston plate 16 forms a sliding seal with the inner wall of the outer tube 6. An air cavity 26 is formed inside the outer tube 6 above the piston plate 16, a one-way air outlet valve 25 is installed in the middle of the piston plate 16, and a one-way air inlet valve 24 is installed on the top of the outer tube 6. The position of the one-way air outlet valve 25 corresponds to the position of the one-way air inlet valve 24. When the slide plate 12 moves downward, the piston plate 16 will also move downward, so that negative pressure is generated in the air cavity 26, and the air cavity 26 will inhale air through the one-way air inlet valve 24, and the outer tube 6 will be lifted up first through the lifting mechanism. Since the bottom cover 10 is subject to its own gravity, it will not be lifted first, and it will not be lifted up until the rack 9 is completely pulled out, and then the bottom cover 10 will be lifted up by the rack 9. When the rack 9 is pulled out, it will drive the slide plate 12 to move upward through the gear 13, thereby causing an action opposite to the above-mentioned movement, so that the rotating frame 17 and the monitoring head 15 complete the downward flipping action, and the various sensors on the monitoring head 15 will be exposed for monitoring. When the slide plate 12 moves upward, it drives the piston plate 16 to move upward, and the piston plate 16 compresses the air cavity 26, so that the gas in the air cavity 26 is discharged through the one-way air outlet valve 25. In the process of flipping the monitoring head 15, the gas discharged from the one-way air outlet valve 25 will be sprayed on the sensor on the monitoring head 15, thereby blowing away the dust attached to its surface, thereby playing a cleaning role.

[0032] A slide groove 11 is arranged on the inner side of the outer cylinder 6, and a slider structure cooperating with the slide groove 11 is arranged on the slide plate 12 and the piston plate 16. An empty groove for the rack 9 to slide is arranged inside the outer cylinder 6, and a limiting structure is arranged in the empty groove to prevent the rack 9 from disengaging.

[0033] like Figure 3 , Figure 5 as well as Figure 8 As shown, the bottom of the bottom cover 10 is provided with a through groove 22 for the skateboard 12 to pass through, and the interior of the base 1 is provided with a contraction groove 23 for accommodating the skateboard 12. When the skateboard 12 moves downward, it will pass through the bottom cover 10 and be accommodated in the contraction groove 23, providing space for the movement of the skateboard 12.

[0034] The bottom end of the outer tube 6 and the top end of the bottom cover 10 are provided with matching convex and concave structures, so that the monitoring head 15 can be exposed at the bottom of the outer tube 6 and the bottom cover 10 and the outer tube 6 can be tightly closed.

[0035] Various sensors on the monitoring head 15 are powered by an external power supply and also transmit data with external terminal equipment via data lines.

[0036] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements may be made without departing from the inventive concept of the present invention, which all fall within the protection scope of the present invention.
