[0001] The invention belongs to the technical field of soil temperature and humidity monitoring, and in particular relates to a multi-layer soil temperature and humidity monitoring device and a method thereof. Background Art

[0002] Soil moisture conditions (temperature and humidity) refer to the moisture conditions of the soil, and the monitoring of soil moisture conditions cannot be separated from the support of soil moisture monitoring equipment.

[0003] Most of the existing multi-layer soil temperature and humidity monitoring devices are of tubular type, that is, the temperature and humidity monitor is placed in a tube, and the tube is buried below the ground, so that the temperature and humidity of the soil at different depths can be monitored through the temperature and humidity monitor. When the inventor used this device, he found that when this type of tube is taken out, the outer wall of the tube fits tightly with the soil, resulting in great friction, and the tube cannot be pulled out directly.

[0033] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0034] It should be noted that when an element is referred to as being "disposed on" another element, it may be directly on the other element or there may be another element centered thereon. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be another element centered thereon at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0036] Example 1, please refer to Figure 1 , Figure 2 and Figure 3 A multi-layer soil temperature and humidity monitoring device includes a monitoring tube 3, wherein a plurality of monitors 41 are arranged in the monitoring tube 3, a retractable monitoring probe 4 is arranged at the end of the monitor 41, a temperature and humidity sensor is arranged on the monitoring probe 4, the monitoring tube 3 includes a base 32, a first plate 301 and a second plate 302, a plurality of first plates 301 and a second plate 302 are arranged on the base 32, the first plates 301 and the second plates 302 are staggered, and the first plates 301 and the second plates 302 are mutually attached to form a circular tube, a detachably connected center rod 33 is arranged in the middle of the base 32, a plurality of retractable first rods 331 and a second rod 332 are arranged on the center rod 33, the end of the first rod 331 is detachably connected to the corresponding first plate 301, and the end of the second rod 332 is detachably connected to the corresponding second plate 302. Wherein, the monitor 41 and the monitoring probe 4 are both prior art, and their technical principles and specific structures are not described in detail in this application. The side wall of the monitoring tube 3 is provided with a plurality of monitoring holes which are slidably and sealedly connected to the monitoring probe rod 4. When the monitor 41 is in use, the monitoring probe rod 4 is inserted into the monitoring hole, the monitoring tube 3 is extended, and the soil is inserted for monitoring. Controlling the extension and retraction of the monitoring probe rod 4 is a prior art in the field, so this application does not provide any detailed description of this.

[0037] The monitoring tube 3 adopts the design of the first plate 301 and the second plate 302, and cooperates with the extension and retraction of the first rod 331 and the second rod 332 to drive the first plate 301 and the second plate 302 to contract. The monitoring tube 3 can be separated from the soil in turn by staggered contraction of the first plate 301 and the second plate 302, which can effectively reduce the friction between the soil and the monitoring tube 3. In this way, the user does not need to dig, but only needs to manually remove the monitoring tube 3 from the soil, which is more convenient, quick and efficient.

[0038] See also Figure 1 In this embodiment, it also includes a controller and a solar panel 1. The bottom of the solar panel 1 is provided with a fixing plate for fixing to the ground. The controller is fixed to the inner side of the solar panel 1. A transmission line 2 for signal transmission is provided between the controller and the monitor 41. It also includes a cloud platform. The controller is provided with a network transmission mechanism for transmitting monitoring data to the cloud platform. The cloud platform realizes online monitoring of soil temperature and humidity. Since the cloud platform and the network transmission mechanism are both existing technologies, this application does not describe them in detail.

[0039] See also Figure 2In this embodiment, sealing grooves are provided at both ends of the inner side of the second plate 302, and sealing plates matching the sealing grooves are provided at both ends of the inner side wall of the first rod 331. Sealing rubber is provided in both the sealing groove and the sealing plate.

[0040] The design of the sealing groove and the sealing plate can effectively improve the overall sealing performance of the first plate 301 and the second plate 302 when forming a circular tube, thereby preventing water from entering the monitoring tube 3 .

[0041] See also Figure 2 and Figure 3 In this embodiment, a plurality of extrusion plates 34 are provided in the monitoring tube 3 and can move back and forth and are used for extruding and fitting the connection between the first plate 301 and the second plate 302 .

[0042] The design of the extrusion plate 34 can further improve the sealing of the first plate 301 and the second plate 302 when forming a circular tube by squeezing the connection between the first plate 301 and the second plate 302 through the extrusion plate 34, thereby preventing water from entering the monitoring tube 3.

[0043] See also Figure 2 and Figure 3 In this embodiment, the central rod 33 is provided with a plurality of retractable third rods 334, and the ends of the third rods 334 are provided with fixedly connected synchronous plates 341, and the two ends of the synchronous plates 341 are fixedly connected to the corresponding extrusion plates 34. Through the extension and retraction of the third rods 334 and the synchronization plates 341, the number of the third rods 334 can be reduced, and the extrusion of the extrusion plates 34 is also achieved.

[0044] As a feasible implementation manner, the first rod 331 , the second rod 332 and the third rod 334 are all electric hydraulic rods.

[0045] See also Figure 2 , Figure 3 and Figure 4As a feasible implementation, the first rods 331 are evenly distributed from top to bottom, and each of the second rods 332 is located below the corresponding first rod 331, so that the first rods 331 and the second rods 332 on the center rod 33 are staggered. A polygonal prism-shaped adjustment groove 333 is provided in the middle of the center rod 33. A plurality of through-type driving grooves are provided on the inner wall of the adjustment groove 333. A fixedly connected pressing and telescopic mechanism 336 is provided in each of the driving grooves. The telescopic ends of the pressing and telescopic mechanism 336 are respectively connected to the corresponding first rod 331 and the second rod 332. A plurality of pressing rods 337 are provided in the adjustment groove 333. The pressing rods 337 are connected and fixed to the pressing ends of the pressing and telescopic mechanism 336. The end of the pressing rod 337 located in the adjustment groove 333 is hemispherical. A slidingly connected and up-and-down movable adjustment ring plate is provided in the adjustment groove 333. The pressing and telescopic mechanism 336 adopts the pressing and telescopic mechanism 336 in the existing pressing cylindrical pen. The monitoring probe 4 is located at one of the second plates 302, and the second plate 302 located at one side of the monitoring probe 4 is not connected to the second rod 332, that is, the second plate 302 located at one side of the monitoring probe 4 is not tilted.

[0046] Since the monitoring tube 3 and the soil are closely attached, the suction force of the attachment will inevitably make it difficult for the first plate 301 or the second plate 302 to move back and forth, and the first rod 331 and the second rod 332 are designed with a staggered distribution, and the pressing and retracting mechanism 336, the adjusting ring plate and the pressing rod 337 are used, so that during the movement of the pressing ring from top to bottom, the adjusting ring plate is preferentially pressed by the pressing rod 337 at the first rod 331, driving the uppermost first rod 331 to contract, while the lower first rod 331 remains as it is. Therefore, the contraction of the first rod 331 at this time will inevitably cause the first plate 301 to be tilted. Since the uppermost first plate 301 has a small contact area with the soil and the soil is relatively loose, there will not be much suction force, and this method of only separating a part of the soil will not cause the first plate 301 to be tilted. In this way, it is easier for the first plate 301 to tilt, and as the adjusting ring plate 335 continues to descend, it contacts the adjusting rod at the adjacent second rod 332, driving the second rod 332 to contract, thereby controlling the contraction of the second plate 302. Since the inclination of the first plate 301 no longer affects the second plate 302, the inclination of the second plate 302 will not be affected. As the adjusting ring plate 335 descends, it contacts and squeezes the adjusting rod in the adjusting groove 333 in turn, driving the first rod 331 and the second rod 332 to contract in turn, thereby making the first plate 301 and the second plate 302 tilt alternately, causing the first plate 301 and the second plate 302 to be torn and separated from the soil, greatly reducing the friction between the monitoring tube 3 and the soil, making it more convenient and quick to remove the monitoring tube 3.

[0047] And due to the characteristics of the pressing and retracting mechanism 336, when the adjusting ring plate 335 moves upward from the bottom, after pressing the pressing rod 337 again, the first rod 331 and the second rod 332 will be extended again. Since the second rod 332 is located below the first rod 331, the second plate 302 will preferentially change from inclined to vertical under the action of the second rod 332, and the first plate 301 will fit with the second plate 302 after the second plate 302 is vertical. In this way, the first plate 301 and the second plate 302 can better form a circular tube again.

[0048] See also Figure 2 , Figure 5 In this embodiment, a reciprocating screw rod 338 is provided in the middle of the adjustment groove 333. The reciprocating screw rod 338 passes through the adjustment ring plate, and the reciprocating screw rod 338 and the adjustment ring plate are connected by a reciprocating thread. A card slot 339 is provided at the upper end of the reciprocating screw rod 338.

[0049] The design of the reciprocating screw 338 can realize the up and down movement of the adjustment ring plate 335 by rotating the reciprocating screw 338. The design of the slot 339 enables the user to better rotate the reciprocating screw 338 by means of external devices when controlling the rotation of the reciprocating screw 338.

[0050] See also Figure 6 In this embodiment, the first plate 301 and the second plate 302 are both provided with an adjustment frame 35 that is fixedly connected, a snap-fitting groove 351 is provided on one side of the adjustment frame 35, and the ends of the first rod 331 and the second rod 332 are both provided with a snap-fitting plate 3311 that is fixedly connected and used to snap into the adjustment frame 35. The design of the adjustment frame 35, the snap-fitting groove 351 and the snap-fitting plate 3311 realizes the detachable connection between the first rod 331 and the first plate 301, and the second rod 332 and the second plate 302. The first rod 331 can be separated from the first plate 301, and the second rod 332 can be separated from the second plate 302 by simply rotating.

[0051] See also Figure 1 , Figure 7 In this embodiment, a detachably connected cover plate 31 is provided at the upper end of the monitoring tube 3, and a connecting groove 311 matching the monitoring tube 3 is provided on the cover plate 31. A connecting ring plate 312 matching the center rod 33 is provided in the middle of the connecting groove 311, and a connecting thread is provided between the connecting ring plate 312 and the center rod 33.

[0052] In this embodiment, the center rod 33 and the base 32 can be connected by threads or any other detachable connection method in the prior art.

[0053] When this embodiment is used:

[0054] First, a hole with a diameter larger than the monitoring tube 3 is dug on the ground, and a certain amount of mud is prepared using soil. When in use, the monitoring tube 3 is first placed in the hole and kept vertically, and then the mud is poured into the hole to fill the gap between the monitoring tube 3 and the hole. After that, the fixing plate is fixed to the nearby ground plate, and the solar panel 1 is fixed to the fixing plate, and the controller is connected to the monitoring tube 3 through the transmission line 2. When the mud is dry, the soil temperature and humidity at different depths below the ground can be monitored through the monitoring probe 4;

[0055] When the monitoring tube 3 needs to be disassembled, first control the third rod 334 to shrink to the shortest point, so that the extrusion plate 34 shrinks synchronously, and then only needs to use an external device such as a portable motor to connect its output end with the card slot 339, and then drive the reciprocating screw rod 338 to rotate through the portable motor, so as to drive the adjusting ring plate 335 to move downward in sequence, so that the adjusting ring plate 335 presses the pressing rod 337 in sequence, driving the first rod 331 and the second rod 332 to shrink in sequence, and controlling the shrinkage amount of the first rod 331 to be greater than the shrinkage amount of the second rod 332, so that the first plate 301 and the second plate 302 can be tilted and torn and separated from the inner wall of the hole in sequence, which greatly reduces the friction between the monitoring tube 3 and the inner wall of the hole, and when the adjusting ring plate 335 moves to the bottom, the monitoring tube 3 can be directly taken out at this time, which is very convenient and labor-saving.

[0056] When the monitoring tube 3 needs to be restored, it is only necessary to control the reciprocating screw 338 to continue to rotate, so as to drive the adjustment ring plate 335 to move upward again, so that the first plate 301 and the second plate 302 can be restored to their initial positions, and the extrusion plate 34 can be controlled to extrude and fix the connection between the first plate 301 and the second plate 302 to ensure the overall sealing.

[0057] When the center rod 33 is separated from the monitoring tube 3, it is only necessary to control the monitoring probe 4 to separate from the monitoring hole, and control the rotation of the center rod 33 to separate the locking plate 3311 from the adjustment frame 35. At the same time, due to the rotation of the center rod 33, the center rod 33 is separated from the base 32. At this time, the center rod 33 can be directly taken out, which is convenient for the inspection and maintenance of the monitor 41.

[0058] A multi-layer soil temperature and humidity monitoring method, using the multi-layer soil temperature and humidity monitoring device, comprises the following steps:

[0059] S1 buries the monitoring tube 3 in the ground, and monitors the soil temperature and humidity at different depths underground through the monitoring probes 4 on multiple monitors 41;

[0060] S2 When the monitoring is completed and no further monitoring is needed, it is only necessary to control the first rod 331 to contract, driving the first plate 301 to separate from the adjacent soil, and then control the second rod 332 to contract, driving the second plate 302 to separate from the adjacent soil. At the same time, the contraction amount of the first rod 331 is greater than the contraction amount of the second rod 332. At this time, the monitoring tube 3 can be directly taken out from the ground without digging.
