Description

Technical Field

[0001] This utility model relates to the field of water content monitoring technology, and in particular to an early warning device for water content monitoring. Background Technology

[0002] Soil moisture content generally refers to the absolute moisture content of soil, that is, how many grams of water are contained in 100g of dried soil, also known as soil moisture rate. With the development of technology, soil moisture detection probes have emerged. Soil moisture content can be detected simply by the probe coming into contact with the soil, making it more convenient for staff to monitor soil moisture content. When monitoring soil moisture content, it is usually necessary to detect soil at different depths.

[0003] For example, in the prior art, the patent with authorization announcement number CN220289592U discloses a water content monitoring device for sandy land. This device only requires rotating the drive rod outside the box to move the insertion rod downward, so that the metal probe can be inserted into the soil to detect the water content in the soil. The operator's hands do not need to be put into the box during the whole process, which is not only convenient to use but also avoids hand injuries.

[0004] However, when this device monitors the moisture content of soil at different depths, it only uses a single metal probe inserted into the soil for detection. The detection results are highly random, and the moisture content of soil at the same depth may be uneven, resulting in a large detection error. Therefore, a moisture content monitoring and early warning device is designed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to solve the problems existing in the above-mentioned background technology by proposing an early warning device for monitoring water content.

[0006] The technical problem to be solved by this utility model is to provide an early warning device for monitoring soil moisture content, thereby solving the problem of large detection error angle in the existing technology when detecting soil moisture content.

[0007] This utility model provides an early warning device for monitoring water content, including a vehicle body. A box is fixedly installed at the center of the upper surface of the vehicle body. A through hole is provided through the center of the bottom of the box, and the through hole extends through the bottom surface of the vehicle body. Electric telescopic rods are fixedly installed on the left and right sides of the top of the box. A lifting plate is installed at the output end of the electric telescopic rod. A rotating tube is rotatably installed at the center of the lifting plate. A spiral blade is fixedly installed below the outer surface of the rotating tube. A drive assembly for driving the rotating tube to rotate is installed on the lifting plate and the rotating tube. Soil water content detection probes are provided through the bottom of the rotating tube in four directions: left, right, front, and back. A linkage assembly for driving the soil water content detection probes to extend and retract the rotating tube is also installed inside the rotating tube.

[0008] Preferably, a centimeter scale is fixedly provided above the outer surface of the rotating tube, and the upper part of the rotating tube extends through the top of the box.

[0009] Preferably, a pointed head is fixedly provided at the bottom of the rotating tube, and the pointed head is located at the exact center of the through hole, and the diameter of the spiral blade is smaller than the diameter of the through hole.

[0010] Preferably, the drive assembly includes a motor fixedly installed on the left side of the bottom surface of the lifting plate and a driven pulley fixed above the outer surface of the rotating tube. The output end of the motor is equipped with a driving pulley, and a transmission belt is sleeved between the driving pulley and the driven pulley.

[0011] Preferably, the linkage assembly includes a rotating shaft rotatably disposed inside the rotating tube and four sliding grooves formed at the bottom of the inner side of the rotating tube. A handle is fixedly disposed on the top of the rotating shaft, and an internally threaded collar is threadedly connected to the bottom of the rotating shaft. Four inverted concave frames are fixedly disposed on the side of the internally threaded collar. A connecting rod is rotatably disposed on the inverted concave frame via a pin. A concave frame is rotatably disposed on the other end of the connecting rod via a pin. The concave frame slides in the sliding groove, and the soil moisture content detection probe is fixedly installed on the concave frame.

[0012] Preferably, two adjacent inverted concave frames are arranged perpendicular to each other, and two adjacent sliding grooves are arranged perpendicular to each other.

[0013] Preferably, when the concave frame slides to the side of the slide groove near the rotating shaft, the soil moisture content detection probe is completely retracted into the rotating tube, and when the soil moisture content detection probe is completely extended outside the rotating tube, the distance of extension is not less than the radius of the spiral blade.

[0014] Preferably, a push handle is fixedly provided on the right side surface of the box, and the push handle is covered with a frosted rubber layer.

[0015] Compared with the prior art, this utility model has at least the following beneficial effects:

[0016] 1. This utility model is equipped with a linkage component. When the rotating tube reaches a specified depth in the soil, the linkage component drives four soil moisture content detection probes to extend out of the rotating tube. The four soil moisture content detection probes are inserted horizontally into the soil at the same depth to detect the soil moisture. The average value of the soil moisture content is measured by the four soil moisture content detection probes to ensure the accuracy of the moisture content detection.

[0017] 2. This utility model is equipped with a drive component. The motor drives the active pulley to rotate, and the active pulley drives the driven pulley, rotating tube and spiral blade to rotate through the transmission belt. In addition, the electric telescopic rod extends, driving the lifting plate to move downward, so that the spiral blade drills holes in the soil.

[0018] 3. This utility model, by setting up a linkage component, allows for simultaneous detection of soil moisture content at a specified depth by rotating the tube and rotating the handle. Rotating the handle drives the rotating shaft to rotate, which in turn moves the internal threaded collar upwards. The internal threaded collar, via a connecting rod, pulls the concave frame along the slide groove towards the side closer to the rotating shaft, until the soil moisture content detection probe 12 is fully retracted into the rotating tube. For soil moisture detection at a specified depth, reversing the handle rotates the shaft, causing it to rotate. The shaft then moves the internal threaded collar downwards, and the internal threaded collar, via a connecting rod, pushes the concave frame along the slide groove towards the side farther from the rotating shaft, until the soil moisture content detection probe is fully extended into the rotating tube and inserted into the soil at the specified depth. Four soil moisture content detection probes can simultaneously detect the soil moisture content at a specified depth. Attached Figure Description

[0026] Example:

[0027] like Figures 1-4 As shown, an embodiment of this utility model provides an early warning device for monitoring water content, including a vehicle body 1. A box 2 is fixedly installed at the center of the upper surface of the vehicle body 1. A through hole 3 is provided through the center of the bottom of the box 2, and the through hole 3 passes through the bottom surface of the vehicle body 1. Electric telescopic rods 4 are fixedly installed on the left and right sides of the top of the box 2. A lifting plate 5 is installed at the output end of the electric telescopic rod 4. A rotating tube 6 is rotatably installed at the center of the lifting plate 5. A spiral blade 7 is fixedly installed below the outer surface of the rotating tube 6. A drive assembly for driving the rotating tube 6 to rotate is installed on the lifting plate 5 and the rotating tube 6. Soil water content detection probes 12 are provided through the bottom of the rotating tube 6 in four directions: left, right, front, and back. A linkage assembly for driving the soil water content detection probes 12 to extend and retract the rotating tube 6 is also installed inside the rotating tube 6.

[0028] By setting up a linkage component, when the rotating tube 6 reaches a specified depth in the soil, the linkage component drives four soil moisture content detection probes 12 to extend out of the rotating tube 6. The four soil moisture content detection probes 12 are inserted horizontally into the soil at the same depth to detect soil moisture. The average value of the soil moisture content is measured by the four soil moisture content detection probes 12 to ensure the accuracy of the moisture content detection.

[0029] In this embodiment, a centimeter scale 601 is fixedly provided above the outer surface of the rotating tube 6, and the top of the rotating tube 6 is provided through the top of the box 2, so as to facilitate the distance of downward movement of the rotating tube 6 through the centimeter scale.

[0030] In this embodiment, a pointed head 602 is fixedly provided at the bottom of the rotating tube 6, and the pointed head 602 is located at the center of the through hole 3. The diameter of the spiral blade 7 is smaller than the diameter of the through hole 3, which makes it convenient for the spiral blade 7 to pass through the through hole 3 to drill the soil.

[0031] In this embodiment, the drive assembly includes a motor 8 fixedly installed on the left side of the bottom surface of the lifting plate 5 and a driven pulley 10 fixed above the outer surface of the rotating tube 6. The output end of the motor 8 is equipped with a drive pulley 9, and a transmission belt 11 is sleeved between the drive pulley 9 and the driven pulley 10 to facilitate the motor 8 to drive the rotating tube 6 to rotate.

[0032] With the drive assembly, the motor 8 drives the active pulley 9 to rotate. The active pulley 9 drives the driven pulley 10, the rotating tube 6 and the spiral blade 7 to rotate through the transmission belt 11. In conjunction with the extension of the electric telescopic rod 4, the lifting plate 5 moves downward, so that the spiral blade 7 drills holes in the soil.

[0033] In this embodiment, the linkage component includes a rotating shaft 13 rotatably disposed inside the rotating tube 6 and four sliding grooves 603 formed at the bottom of the inner side of the rotating tube 6. A handle 1301 is fixedly disposed on the top of the rotating shaft 13, and an internal threaded collar 1302 is threadedly connected to the bottom of the rotating shaft 13. Four inverted concave frames 1303 are fixedly disposed on the side of the internal threaded collar 1302. A connecting rod 1304 is rotatably disposed on the inverted concave frame 1303 via a pin. A concave frame 1305 is rotatably disposed on the other end of the connecting rod 1304 via a pin. The concave frame 1305 slides in the sliding groove 603, and the soil moisture content detection probe 12 is fixedly installed on the concave frame 1305.

[0034] In this embodiment, two adjacent inverted concave frames 1303 are arranged perpendicular to each other, and two adjacent sliding grooves 603 are arranged perpendicular to each other.

[0035] In this embodiment, when the concave frame 1305 slides to the side of the slide groove 603 near the rotating shaft 13, the soil moisture content detection probe 12 is completely retracted into the rotating tube 6, and when the soil moisture content detection probe 12 is completely extended out of the rotating tube 6, the distance of extension is not less than the radius of the spiral blade 7, so that the soil moisture content detection probe 12 can be inserted laterally into the soil of the hole drilled by the spiral blade 7.

[0036] With the linkage component, when rotating the rotating tube 6, rotating the handle 1301 causes the rotating shaft 13 to rotate, which in turn causes the internal threaded collar 1302 to move upward. The internal threaded collar 1302, through the connecting rod 1304, pulls the concave frame 1305 along the slide groove 603 towards the side closer to the rotating shaft 13, until the soil moisture content detection probe 12 is completely retracted into the rotating tube 6. When detecting soil at a specified depth, reversing the handle 1301 causes the rotating shaft 13 to rotate, which in turn causes the internal threaded collar 1302 to move downward. The internal threaded collar 1302, through the connecting rod 1304, pushes the concave frame 1305 along the slide groove 603 away from the rotating shaft 13, until the soil moisture content detection probe 12 is fully extended into the rotating tube 6 and inserted into the soil at the specified depth. The four soil moisture content detection probes 12 can simultaneously detect the soil moisture content at the specified depth.

[0037] In this embodiment, a push handle 201 is fixedly installed on the right side surface of the box 2. The push handle 201 is covered with a frosted rubber layer to facilitate the movement of the device by pushing the push handle 201. An alarm is also installed on the box 2. The alarm is electrically connected to the soil moisture detection probe 12. When the soil moisture detection probe 12 detects that the soil moisture is too high or too low, the alarm will sound.

[0038] In actual use, by pushing the device to the position where soil moisture content needs to be detected, the handle 1301 is turned. The handle 1301 drives the rotating shaft 13 to rotate. The rotating shaft 13 drives the internal threaded collar 1302 to move upward. The internal threaded collar 1302 pulls the concave frame 1305 along the slide groove 603 to the side closer to the rotating shaft 13 through the connecting rod 1304 until the soil moisture content detection probe 12 is completely retracted into the rotating tube 6. Then the motor 8 is turned on, driving the active pulley 9 to rotate. The active pulley 9 drives the driven pulley 10, the rotating tube 6 and the spiral blade 7 to rotate through the transmission belt 11. The electric telescopic rod 4 drives the lifting plate 5 to move downward. The spiral blade 7 achieves the effect of drilling holes in the soil. The drilling depth is observed through the centimeter scale 601.

[0039] When the rotating tube 6 reaches the specified depth, reverse the handle 1301. The handle 1301 drives the rotating shaft 13 to rotate, and the rotating shaft 13 drives the internal threaded collar 1302 to move downward. The internal threaded collar 1302 pushes the concave frame 1305 along the slide groove 603 away from the rotating shaft 13 through the connecting rod 1304 until the soil moisture content detection probe 12 is fully extended into the rotating tube 6 and inserted into the soil at the specified depth. The four soil moisture content detection probes 12 can simultaneously detect the soil moisture content at the specified depth. The accuracy of soil moisture content detection can be ensured by averaging the moisture content detected by the four soil moisture content detection probes 12.

[0040] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these should also be considered within the scope of protection of this utility model. These will not affect the implementation effect of this utility model or the practicality of the patent.
