Description

Technical Field

[0001] This invention relates to the field of soil testing technology, and in particular to a moisture monitoring device based on saline-alkali soil. Background Technology

[0002] Saline-alkali land is a general term for salt land, alkali land, salinized land, and alkalized land. It refers to soil with excessively high salt content, which affects the normal growth of crops. Saline-alkali soil has poor soil structure, is prone to compaction, has low organic matter content, is nutrient-poor, and has weak soil fertility retention capacity. It is a degraded soil with poor properties and low fertility. In severely saline-alkali soil areas, plants can hardly survive.

[0003] The soil moisture monitoring device for saline-alkali land is a specialized instrument for accurately measuring and monitoring the moisture content of saline-alkali soil. A sensor probe is installed on one side of the device, directly contacting the soil. Different soil moisture levels result in different dielectric constants, causing the probe to generate varying capacitance values. These changes are converted into corresponding electrical signals and displayed on the digital screen of the instrument for subsequent processing and analysis. When not in use, the probe is typically exposed to the elements. Saline-alkali land is often windy and dusty, and prolonged exposure allows dust to easily adhere to its surface and even penetrate into internal gaps and pores. Over time, these dust particles rub against the sensitive components of the probe, wearing down the protective layer or damaging internal circuit connections, accelerating aging, shortening its lifespan, and interfering with the probe's normal sensing and data acquisition of soil moisture.

[0027] Compared with the prior art, the present invention has at least the following beneficial effects:

[0028] 1. This invention, through the mutually adaptable design of the pop-up components, allows the detection head to be retracted when not in use, preventing it from being directly exposed to the outside. After retraction, the detection head is protected from prolonged exposure to wind and sand, preventing sand and dust from adhering to its surface or entering internal gaps and pores. The sensitive components of the detection head will not suffer from wear on the surface protective layer or damage to the internal circuit connections due to friction from sand and dust particles, thereby extending its service life.

[0029] 2. This invention cleans the surface of the detection head by using multiple sets of arc-shaped sponge plates when the detection head extends out of the rotating cylinder, restoring the surface of the detection head to cleanliness. This ensures good contact with the soil when inserted into saline-alkali soil for testing, avoiding the impact of impurities on the accurate perception of soil moisture. At the same time, the elastic force of the first tension spring can drive the arc-shaped sponge plate on the first positioning slide rod to adhere tightly to the surface of the detection head, thereby improving the cleaning effect. Meanwhile, the rebound force of the second tension spring pulls the fan-shaped sponge blocks on the second positioning slide rod closer to each other inside the rotating cylinder, thereby blocking and sealing the top of the rotating cylinder, thus preventing dust and other impurities from falling from the rotating cylinder into the detection head.

[0030] 3. This invention, through the adjustable extension length of the detection head, can accurately extend the detection head to different soil depths for measurement, avoiding the problem of varying soil moisture at different depths in saline-alkali soils, thereby achieving monitoring of soil layers at different depths, and has high flexibility and applicability.

[0054] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0055] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0056] Example 1

[0057] Reference Figures 1-17 This is the first embodiment of the present invention. This embodiment provides a moisture monitoring device based on saline-alkali soil, which includes a pop-out component 21, a rotating component 3 and a main component 1. The cooperation of the three components can make the detection effect more accurate.

[0058] The pop-out component 2 includes a pop-out assembly 21 and a connecting assembly 22. The pop-out assembly 21 includes a pop-out plate 211 disposed on the surface of the detection head 11. A first spring 212 is fixed to the bottom end of the pop-out plate 211. A positioning rod 213 is connected to the top end of the pop-out plate 211 and passes through the pop-out plate 211. The first spring 212 is slidably sleeved on the bottom end of the surface of the positioning rod 213. A rotating cylinder 214 is disposed on one side of the pop-out plate 211. A rotating wheel 215 is fixed to one side of the rotating cylinder 214. A drive wheel 216 is disposed on one side of the rotating wheel 215.

[0059] Preferably, the pop-out component 21 further includes a cleaning component 23. The cleaning component 23 includes multiple sets of first positioning slide rods 231 disposed at the bottom end of the surface of the rotating cylinder 214, with one end of the first positioning slide rod 231 extending into the inner cavity of the rotating cylinder 214; an arc-shaped sponge plate 233 disposed at one end of the first positioning slide rod 231 located in the inner cavity of the rotating cylinder 214; a first blocking cover 232 disposed at one end of the first positioning slide rod 231 away from the arc-shaped sponge plate 233; a first tension spring 235 disposed on the surface of the first positioning slide rod 231 near the end of the first blocking cover 232; two sets of first auxiliary slide rods 234 disposed on the arc-shaped sponge plate 233 near the end of the rotating cylinder 214, with one end of the first auxiliary slide rod 234 slidingly extending to the outside of the rotating cylinder 214; one end of the first tension spring 235 is connected to the surface of the rotating cylinder 214, and the other end of the first tension spring 235 is connected to the surface of the first blocking cover 232.

[0060] Multiple sets of second positioning slide rods 236 are provided on the top surface of the rotating cylinder 214, and one end of the second positioning slide rod 236 extends into the inner cavity of the rotating cylinder 214. A fan-shaped sponge block 238 is provided at one end of the second positioning slide rod 236 located in the inner cavity of the rotating cylinder 214. A second blocking cover 237 is provided at one end of the second positioning slide rod 236 away from the fan-shaped sponge block 238. A second tension spring 230 is provided on the surface of the second positioning slide rod 236 near one end of the second blocking cover 237. Two sets of second auxiliary slide rods 239 are provided on one end of the fan-shaped sponge block 238 near one end of the rotating cylinder 214, and one end of the second auxiliary slide rod 239 slides to the outside of the rotating cylinder 214. One end of the second tension spring 230 is connected to the surface of the rotating cylinder 214, and the other end of the second tension spring 230 is connected to the surface of the second blocking cover 237.

[0061] When the detection head 11 is not in use, it can be squeezed to store the detection head 11 in the support frame 221. When the detection head 11 is squeezed, the pop-out plate 211 can be moved on the positioning rod 213. At this time, the first spring 212 can be squeezed. When the detection head 11 needs to be used, the limit of the detection head 11 is released, and then the force of the rebound of the first spring 212 can drive the detection head 11 to move and extend it.

[0062] The rotating wheel 215 is rotatably connected to one side of the support frame 221 via a bearing, and the drive wheel 216 is rotatably connected to the inner wall of the support frame 221 via a rotating shaft. A locking pin is fixed to one side of both the rotating wheel 215 and the drive wheel 216, and the locking pins on the rotating wheel 215 and the drive wheel 216 engage. When the detection head 11 pops out, it can drive the drive wheel 216 to rotate. At this time, the rotation of the drive wheel 216 drives the rotating wheel 215 to rotate, which in turn drives the rotating cylinder 214 to rotate. This causes the multiple sets of arc-shaped sponge plates 233 on the rotating cylinder 214 to rotate and rub against the surface of the detection head 11, thereby rubbing against the detection head 11. The surface is cleaned, and the elastic force of the first tension spring 235 can drive the arc-shaped sponge plate 233 on the first positioning slide rod 231 to stick tightly to the surface of the detection head 11, thereby improving the cleaning effect. At the same time, when the detection head 11 moves out of the rotating cylinder 214, it will lift the fan-shaped sponge block 238. When the detection head 11 retracts from the rotating cylinder 214, the rebound force of the second tension spring 230 will pull the fan-shaped sponge block 238 on the second positioning slide rod 236 to move closer to each other inside the rotating cylinder 214, thereby blocking and sealing the top of the rotating cylinder 214, thus preventing dust and other impurities from falling from the rotating cylinder 214 onto the detection head 11.

[0063] The rotating component 3, mounted on the pop-out assembly 21, includes a moving block 311, a pull rope 312, a winding wheel 313, a coil spring 314, a rotating disk 315, a locking block 316, a first torsion spring 317, and a rotating shell 318. The moving block 311 is located on the pop-out assembly 21. The pull rope 312 is fixed to the bottom of the moving block 311. The winding wheel 313 is located inside the pull rope 312. The coil spring 314 is fixed to one side of the winding wheel 313. The rotating disk 315 is fixed to one side of the coil spring 314. The locking block 316 is hinged to the inside of the rotating disk 315. One end of the first torsion spring 317 is fixed to the inner wall of the rotating disk 315, and the other end is fixed to one side of the locking block 316. The rotating shell 318 is sleeved on the outside of the rotating disk 315.

[0064] When the detection head 11 pops out, it can move the pull rope 312. The movement of the pull rope 312 can drive the winding wheel 313 to rotate. At this time, the rotation of the winding wheel 313 can apply a torsional force to the winding spring 314. When the winding spring 314 rotates, it can drive the rotating disk 315 to rotate. The rotation of the rotating disk 315 can drive the locking block 316 to rotate. The rotating shell 318 has a sloped groove corresponding to the locking block 316. The rotation of the locking block 316 can squeeze the sloped groove to make the rotating shell 318 rotate. The rotation of the rotating shell 318 can drive the drive disk 321 to rotate. The rotation of the drive disk 321 can drive the limit wheel 326 to rotate. At the same time, it can move the slot plate 336. When the slot plate 336 moves to squeeze the limit block 327, it engages with the slot on the limit wheel 326 to limit it. At this time, the detection head 11 can be stopped from moving. By moving the slot plate 336 to different positions, the pop-out position of the detection head 11 can be adjusted.

[0065] When the detection head 11 is retrieved, the pull rope 312 returns to its original position. Then, the winding wheel 313 can be driven to rotate by the force of the spring 314, thereby winding up the pull rope 312. When the spring 314 rotates, it can drive the rotating disk 315 to rotate. At this time, the rotating disk 315 can drive the locking block 316 to reverse. The locking block 316 is squeezed by the inclined locking groove on the rotating shell 318, causing it to move into the rotating disk 315. At this time, a torsional force can be applied to the first torsion spring 317. When the inclined locking groove separates from the locking block 316, the force of the first torsion spring 317 can drive the inclined locking groove and the locking block 316 to re-engage. This process repeats without causing the rotating shell 318 to rotate.

[0066] Example 2

[0067] Reference Figures 1-17 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0068] Specifically, the pop-out component 21 also includes a connecting component 22, which is disposed on the pop-out component 21. A support frame 221 is sleeved on the positioning rod 213, and a locking plate 222 is disposed on the top of the support frame 221. A locking frame 223 is sleeved on the locking plate 222.

[0069] The support frame 221 is fixed to one side of the humidity monitor 12 and is sleeved on the outside of the detection head 11. The support frame 221 is movably connected to the detection head 11. The support frame 221 can protect the detection head 11. The locking plate 222 is fixed to the top of the detection head 11. The locking plate 222 has an inclined surface. The locking frame 223 has a corresponding locking hole. After the detection head 11 is stored in the support frame 221, in order to prevent the force of the first spring 212 from causing the detection head 11 to extend, the locking plate 222 is engaged with the locking hole to limit the detection head 11. The locking plate 222 has a certain elasticity. By pressing the locking plate 222 to separate it from the locking hole, the limitation on the detection head 11 can be released. Then, the force of the first spring 212 can cause the detection head 11 to pop out. When the locking plate 222 is released, its own elasticity can return to its original position, which is convenient for engaging with the locking hole.

[0070] Specifically, a first pulley 224 is fixed to one side of the drive wheel 216, a belt 225 is fitted on the first pulley 224, and a second pulley 226 is provided inside the belt 225.

[0071] The second pulley 226 is fixed to one side of the limiting wheel 326. The second pulley 226 is rotatably connected to the positioning box 3201 through a rotating shaft. When the limiting wheel 326 rotates, it can drive the second pulley 226 to rotate. The rotation of the second pulley 226 can drive the belt 225 to rotate. The rotation of the belt 225 can drive the first pulley 224 to rotate. At this time, the rotation of the first pulley 224 can drive the drive wheel 216 to rotate, so that the surface of the detection head 11 can be cleaned when it extends.

[0072] Specifically, the rotating component 3 also includes a movable component 32, which is disposed on the rotating shell 318.

[0073] When the rotating shell 318 rotates, it can drive the drive disk 321 to rotate. The rotation of the drive disk 321 can drive the drive bar 322 to move. At this time, the movement of the drive bar 322 can squeeze the drive frame 323 to move it. The movement of the drive frame 323 can drive the movable bar 324 to move. At this time, the movement of the movable bar 324 can drive the slot plate 336 to move. The positioning frame 325 can support the movable bar 324 to prevent the movable bar 324 from shifting.

The second spring 3202 is fixed to the inner wall of the positioning box 3201.

[0075] A limiting groove corresponding to the limiting block 327 is provided on the limiting wheel 326. The movement of the hinge rod 329 can drive the extrusion wheel 328 to move. When the hinge rod 329 moves, it can apply a torsional force to the second torsion spring 320. The extrusion wheel 328 moves to contact one side of the limiting block 327 and extrudes it to make it move. By moving the limiting block 327 to engage with the limiting groove, the limiting wheel 326 can be limited. When the slider 3200 moves, it can drive the slider... 3200 moves within the positioning box 3201. At this time, a squeezing force can be applied to the second spring 3202. When it is necessary to release the restriction on the limiting wheel 326, the force of the second torsion spring 320 rotating drives the hinge rod 329 to return to its original position to release the squeezing on the limiting block 327. Then, the limiting block 327 can be driven to return to its original position and separate from the limiting wheel 326 by the force of the second spring 3202 rebound, thereby releasing the restriction on the limiting wheel 326.

[0076] Specifically, the rotating component 3 also includes a translation component 33, which is mounted on the drive frame 323. A slide rod 331 is fixed to one side of the drive frame 323, and a positioning block 332 is sleeved on the slide rod 331. The slide rod 331 and the positioning block 332 are movably connected.

[0077] The slot plate 336 has a translation groove corresponding to the inclined plate 334. Both the translation groove and the inclined plate 334 are inclined surfaces. When the drive frame 323 moves, it can drive the slide rod 331 to move. The movement of the slide rod 331 can drive the movable rod 333 to move. The movement of the movable rod 333 can drive the inclined plate 334 to move. At this time, it can squeeze the translation groove, thereby making the slot plate 336 move. When the drive frame 323 returns to its original position, it drives the inclined plate 334 to return to its original position. At this time, the inclined plate 334 will flip. When the inclined plate 334 flips, it can apply a torsional force to the third torsion spring 335. When the inclined plate 334 moves to the point of separating from the translation groove, the force of the rotation of the third torsion spring 335 can drive the inclined plate 334 to rotate back to its original position and re-engage with the translation groove. Then the slot plate 336 can be pushed again. By repeating this process, the slot plate 336 can be continuously pushed.

[0078] A slider 3200 is provided on one side of the slot plate 336. A longitudinal groove corresponding to the slider 3200 is provided on the inner wall of the connecting frame 337.

The rebound force of the third spring 338 drives the slot plate 336 back to its original position and re-engage with the inclined plate 334.

[0079] Example 3

[0080] Reference Figures 1-17 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0081] Specifically, a pressing frame 339 is fixed on one side of the slot plate 336, a pressing post 330 is provided at one end of the hinge rod 329, the pressing post 330 and one end of the hinge rod 329 are hinged, a connecting box 3300 is sleeved on the connecting frame 337, the connecting frame 337 and the connecting box 3300 are slidably connected, a moving plate 3301 is fixed on the top of the connecting frame 337, a fourth spring 3302 is fixed on one side of the moving plate 3301, and the fourth spring 3302 is fixed to the inner wall of the connecting box 3300.

[0082] When the slot plate 336 moves, it can drive the compression frame 339 to move. The compression frame 339 is set with an inclined surface. By moving the compression frame 339 to the top of the lower pressure column 330, it can be compressed and moved. The movement of the lower pressure column 330 can compress the hinge rod 329. A return torsion spring is fixed on one side of the lower pressure column 330 and is fixed to the inner wall of the hinge rod 329. The elastic force of the return torsion spring can support the lower pressure column 330 and prevent it from shifting. By moving the slot plate 336, the compression frame 339 can be separated from the lower pressure column 330. The position of the inclined side of the compression frame 339 is set with an arc surface. The return of the slot plate 336 to its original position can also drive the compression frame 339 to move. The extrusion frame 339 is separated from the lower pressure column 330. The connecting box 3300 is fixed to one side of the support frame 221. A support block is fixed on one side of the connecting box 3300. A support groove is opened on the inner wall of the support frame 221. The support block slides in the support groove. The connecting box 3300 can support the connecting frame 337. When the slot plate 336 moves, it can drive the connecting frame 337 to move. The movement of the connecting frame 337 can drive the moving plate 3301 to move. The movement of the moving plate 3301 can apply a pulling force to the fourth spring 3302. The rebound force of the fourth spring 3302 can drive the connecting frame 337 to return to its original position, thereby driving the slot plate 336 to return to its original position.

[0083] Specifically, the rotating component 3 also includes a pulling assembly 34, which is disposed on the slot plate 336. A moving strip 341 is fixed to the top of the slot plate 336. A connecting frame 337 is sleeved on the outside of the moving strip 341. The connecting frame 337 and the moving strip 341 are movably connected. A movable plate 342 is fixed to the top of the moving strip 341. An inclined block 343 is provided at the bottom of the movable plate 342. A locking plate 344 is provided at the bottom of the inclined block 343. The locking plate 344 is fixed to the top of the connecting box 3300.

[0084] The locking plate 344 has a locking groove corresponding to the inclined block 343. The locking groove is set as an inclined surface. When the connecting frame 337 moves, it can drive the moving bar 341 to move. The movement of the moving bar 341 can drive the moving plate 342 to move. At this time, the movement of the moving plate 342 can drive the inclined block 343 to move on the surface of the locking plate 344. Then, the engagement of the inclined block 343 with the locking groove can prevent the connecting frame 337 from returning to its original position. When it is necessary to release the restriction on the connecting frame 337, the inclined block 343 is moved to separate it from the locking plate 344. At this time, the connecting frame 337 can return to its original position.

[0085] Specifically, a pull bar 345 is fixed to the top of the inclined block 343, and a connecting sleeve 346 is fitted on the pull bar 345. The connecting sleeve 346 and the pull bar 345 are movably connected. The connecting sleeve 346 is fixed to the top of the movable plate 342. A pressure plate 348 is fitted on the pull bar 345, and a fifth spring 347 is fixed to the top of the pressure plate 348. The fifth spring 347 is fixed to the inner wall of the connecting sleeve 346.

[0086] Pulling the pull bar 345 can move the pressure plate 348. When the pressure plate 348 moves, it can apply a squeezing force to the fifth spring 347. At this time, the movement of the pull bar 345 can move the inclined block 343 to separate from the locking plate 344, thereby releasing the limit on the connecting frame 337. When the pull bar 345 is released, the rebound force of the fifth spring 347 can drive the inclined block 343 back to its original position and re-engage with the locking plate 344. The connecting sleeve 346 is used to support the pull bar 345 and prevent the pull bar 345 from shifting.

[0087] Specifically, it also includes the main body component 1, which is set on the pop-out plate 211, including a detection head 11 and a humidity monitor 12. The detection head 11 is fixed to one side of the pop-out plate 211, and the humidity monitor 12 is fixed to one side of the support frame 221.

[0088] The detection head 11 is in direct contact with the saline-alkali soil. When the soil moisture is different, its dielectric constant will be different. The detection head 11 will generate different capacitance values ​​accordingly. These changes will be converted into corresponding electrical signals and displayed on the digital display screen of the humidity monitor 12 for subsequent processing and analysis.

[0089] In use, first move the slot plate 336 to the designated position and adjust the pop-out position of the detection head 11. First, pull the pull bar 345 to move the pressure plate 348. The movement of the pressure plate 348 can apply a squeezing force to the fifth spring 347. At this time, the movement of the pull bar 345 can move the inclined block 343 to separate from the locking plate 344, thereby releasing the limit on the connecting frame 337. Then, move the movable plate 342. The movement of the movable plate 342 can move the connecting frame 337. At this time, the movement of the connecting frame 337 can move the slot plate 336. The slot plate 336 can move the moving plate 3301. The movement of the moving plate 3301 can apply a pulling force to the fourth spring 3302. Then, the slot plate 336 moves horizontally to move the compression frame 339 to the designated position. At this time, the pop-out position of the detection head 11 can be adjusted.

[0090] By pressing the locking plate 222 to separate it from the lock hole, the limiting position on the detection head 11 can be released. Then, the rebound force of the first spring 212 can cause the detection head 11 to pop out. When the detection head 11 pops out, it can move the pull rope 312. The movement of the pull rope 312 can drive the winding wheel 313 to rotate. At this time, the rotation of the winding wheel 313 can apply a torsional force to the winding spring 314. When the winding spring 314 rotates, it can drive the rotating disk 315 to rotate. The rotation of the rotating disk 315 can drive the locking block 316 to rotate. The rotating shell 318 has a sloped groove corresponding to the locking block 316. The rotation of the locking block 316 can squeeze the sloped groove to make the rotating shell 318 rotate. The rotation of the rotating shell 318 can drive the drive disk 321 to rotate. The rotation of the drive disk 321 drives the limiting wheel 326 to rotate, and at the same time drives the drive... When the drive bar 322 moves, it can press the drive frame 323 to move. When the drive frame 323 moves, it can drive the slide bar 331 to move. The slide bar 331 moves, which can drive the movable rod 333 to move. The movable rod 333 moves, which can drive the inclined plate 334 to move. At this time, it can press the translation groove, thereby causing the slot plate 336 to move. When the drive frame 323 returns to its original position, it drives the inclined plate 334 to return to its original position. At this time, the inclined plate 334 will flip. When the inclined plate 334 flips, it can apply a torsional force to the third torsion spring 335. When the inclined plate 334 moves to the point of separating from the translation groove, the force of the rotation of the third torsion spring 335 can drive the inclined plate 334 to rotate back to its original position and re-engage with the translation groove. Then, the slot plate 336 can be pushed again. By repeating this process, the slot plate 336 can be continuously pushed.

[0091] When the slot plate 336 moves, it can drive the extrusion frame 339 to move. By moving the extrusion frame 339 to the top of the pressure column 330, it can be extruded and moved. The movement of the pressure column 330 can extrude the hinge rod 329. The movement of the hinge rod 329 can drive the extrusion wheel 328 to move. The extrusion wheel 328 moves to contact the side of the limit block 327 and extrudes and moves. By moving the limit block 327 to engage with the limit groove, the limit wheel 326 can be limited. At this time, by limiting the limit wheel 326, the drive disc 321 can be limited and stopped from rotating, thereby stopping the winding wheel 313 from rotating. The limitation of the winding wheel 313 can limit the pull rope 312, thereby stopping the detection head 11 from popping out, so as to adjust the pop-out position of the detection head 11.
