Description

Technical Field

[0001] This utility model belongs to the field of soil monitoring technology, specifically relating to an embedded soil monitoring device. Background Technology

[0002] By monitoring information such as soil temperature and humidity, we can better understand soil conditions, which will help us to rationally plan agricultural production, engineering construction, and other activities such as irrigation. Soil monitoring requires the use of monitoring devices.

[0003] In related existing technologies, such as Chinese Patent No. CN216410439U, a soil temperature monitoring device for pre-buried underground pipes is disclosed. This device includes an information feedback box, a control motor fixedly installed at the bottom of the box, an outer rod movably installed below the motor, a temperature measuring block fixedly installed at the bottom of the outer rod, and symmetrically movably mounted closed protective plates on the outside of the information feedback box. An adjusting positioning plate is movably installed at the bottom of the closed protective plates. The control motor controls the raising and lowering of the outer rod, allowing the temperature measuring block to reach and be fixed at the pre-buried position of the underground pipe. The information feedback box also provides remote control of the motor's operation and positioning, facilitating later retrieval and maintenance by technicians. Opening the closed protective plates ensures the safety of the information feedback box in the field, and adjusting the angle of the adjusting positioning plate ensures it contacts the ground laterally, improving the device's stability.

[0004] However, in actual use, the control motor needs to drive the drill bit to rotate, which in turn requires the threaded push rod, outer rod, and drill bit to rotate synchronously. Because the outer rod is movably connected to the threaded push rod and there are no other limiting structures, the position of the outer rod relative to the threaded push rod is difficult to stabilize. Furthermore, when the top of the outer rod is not in contact with the closed protective plate, the user's downward pressure cannot be transmitted to the outer rod through the threaded push rod, making it difficult for the drill bit to spontaneously penetrate the soil layer due to the resistance of the soil below. In summary, the reliability of the extension structures in the above solution is poor, which is detrimental to practical use. Utility Model Content

[0005] The present invention aims to provide an embedded soil monitoring device to solve the problem of poor reliability of existing devices mentioned above.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an embedded soil monitoring device, comprising...

[0007] The enclosure contains a motor and an information collection module.

[0008] The telescopic rod assembly includes an extension rod and an extension tube. The side wall of the extension rod has a protrusion, and the extension tube has a slot. The slot has a groove in its circumference. The slot is adapted to the extension rod, and the groove is adapted to the protrusion. The movable end of the motor is connected to the extension rod.

[0009] The limiting cylinder is rotatably mounted on the extension cylinder. The limiting cylinder is slidably fitted onto the extension rod, and the limiting cylinder slides in cooperation with the protrusion. The outer wall of the limiting cylinder is fitted with a limiting bolt. The side wall of the extension rod is provided with multiple limiting holes spaced apart. The end of the limiting bolt can be threaded into the limiting hole.

[0010] The monitoring cylinder is fixed to the bottom of the extension cylinder. The monitoring cylinder contains a monitoring module, and a monitoring window is provided on the side wall of the monitoring cylinder.

[0011] The drill bit is fixed to the bottom of the monitoring cylinder.

[0012] The principle and effects of this technical solution:

[0013] 1. The protrusion allows the extension rod to rotate synchronously with the extension cylinder, thus enabling the monitoring cylinder and drill bit to rotate synchronously. The extension cylinder can slide relative to the extension rod to change the overall length of the telescopic rod assembly. Furthermore, the insertion and threaded engagement of the limiting cylinder and limiting hole with limiting bolts restricts and fixes the position of the limiting cylinder relative to the extension rod, thereby stabilizing the position of the extension cylinder relative to the extension rod. This ensures that the extension cylinder and extension rod can not only rotate synchronously but also apply axial pressure, allowing the monitoring cylinder to penetrate to a specified depth, thus improving the stability of the device.

[0014] 2. Soil information is collected and monitored through the monitoring module and monitoring window inside the monitoring cylinder. The information collection module can collect and statistically analyze the information monitored by the monitoring module, so as to facilitate subsequent processing and recording.

[0015] The present invention is further configured to include a dustproof component, which includes a connecting cylinder and a bellows respectively sleeved on the extension rod. The connecting cylinder is rotatably installed at the bottom of the box, the top of the bellows is connected to the connecting cylinder, the bottom of the bellows is connected to the limiting cylinder, and the connecting cylinder is slidably engaged with the protrusion.

[0016] The principle and effect of this technical solution are as follows: By making the connecting cylinder slide with the protrusion, and the connecting cylinder is fitted outside the extension rod, the rotation of the extension rod will drive the connecting cylinder to rotate synchronously. At the same time, the limiting cylinder also rotates synchronously with the extension rod. Consequently, the corrugated pipe connected to the connecting cylinder and the limiting cylinder can also rotate synchronously with the extension rod, thereby avoiding the corrugated pipe from twisting and deforming. Furthermore, due to the strong extensibility of the corrugated pipe, it can shield the part of the extension rod that does not overlap with the extension cylinder. This prevents soil from entering the gap between the extension rod and the extension cylinder when the device penetrates into the soil layer, avoiding interference and influence of soil on the connection between the extension rod and the extension cylinder, and ensuring the stability of the device during long-term use.

[0017] The present invention is further configured to include a cross handle, which is fixed to the bottom of the box body, and the projection of the end of the cross handle on the horizontal plane is located outside the projection of the box body on the water surface.

[0018] The principle and effect of this technical solution: By setting the cross handle, the user can control the device by holding the cross handle when drilling into the soil, without having to hold the box. Compared with holding the box, holding the cross handle is safer and more convenient, and it is easier to observe the position of the telescopic rod assembly while applying pressure to make the drill bit drill into the soil.

[0019] The present invention is further configured such that: a column is fixed to the end of the cross handle, and the bottom edge of the column is lower than the bottom edge of the cross handle.

[0020] The principle and effect of this technical solution: By making the bottom edge of the platform lower than the bottom edge of the cross handle, after the drill bit, monitoring cylinder and telescopic rod assembly reach the specified depth of the soil, the platform comes into contact with the top surface of the soil. The platform lifts the box off the bottom surface, preventing water from the soil from soaking into the box when it rains, thus protecting the motor and information collection module inside the box.

[0021] The present invention is further configured to include a tapered rod, and a through hole is provided at the top of the column, with the tapered rod slidably inserted into the through hole.

[0022] The principle and effect of this technical solution: After the platform is in contact with the ground, the cone rod is inserted into the platform, and then the sharp end of the cone rod is driven into the soil by stepping on or pressing it. At this time, the cone rod can fix the soil to a certain extent. At the same time, the cone rod can stabilize and restrict the position of the platform, so that the device is not prone to positional displacement during long-term burial, thus improving the stability of the device during long-term burial and use.

[0023] The present invention is further configured to include a cover plate, a control panel installed on the top of the box, a connecting groove circumferentially provided on the top of the box, a connecting plate fixed on the bottom surface of the cover plate, the connecting plate being slidably inserted into the connecting groove, and the projection of the box on the horizontal plane being located inside the projection of the cover plate on the horizontal plane.

[0024] The principle and effect of this technical solution: The control panel allows users to easily control the working status of components such as motors and information collection modules, and facilitates data observation and collection. The cover prevents rainwater from soaking the electronic components during long-term use, thus extending the device's lifespan.

[0025] The present invention is further configured such that: a photovoltaic panel is installed on the top surface of the box, and the cover plate is a transparent acrylic plate.

[0026] The principle and effect of this technical solution: By installing photovoltaic panels, the power supply of the motor and information collection module inside the box can be replenished, thereby extending the service life of the equipment. Attached Figure Description

[0047] The telescopic rod assembly includes an extension rod 210 and an extension cylinder 220.
