Description

Technical Field

[0001] This utility model relates to the field of soil temperature, humidity and salinity detection technology, specifically a soil temperature, humidity and salinity detection device. Background Technology

[0002] Soil temperature, humidity, and salinity are key parameters closely monitored in agricultural production, having a comprehensive impact on crop growth, nutrient absorption, and soil health. Soil temperature, humidity, and salinity testing involves separately measuring soil temperature, humidity, and salinity. Depending on the specific testing requirements, these parameters are typically measured in the top 0-20cm or 0-60cm soil layer. Before testing, a detection hole must be dug, and then a probe is inserted into the hole to make the measurements.

[0003] Current methods for soil moisture testing typically involve first digging a test hole and then placing a test probe in the hole. For shallow soil testing, the probe is simply inserted into the test hole without a fixed structure, making it easy for the probe to move and affecting the test results. Furthermore, for deeper soil testing, multiple test devices need to be set up at different soil layers. The more test devices there are, the higher the probability of malfunctions. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a soil temperature, humidity and salinity detection device to address the above-mentioned shortcomings.

[0005] To solve the above technical problems, the present invention adopts the following technical solution: A soil temperature, humidity, and salinity detection device includes a detector body, a shallow probe, a deep probe, a shallow probe fixing assembly, a deep probe fixing assembly, and a probe depth positioning structure. The shallow probe fixing assembly is fixedly disposed on the outside of the shallow probe and is used to fix the shallow probe in a shallow soil detection hole. The deep probe fixing assembly is used to fix the deep probe. The probe depth positioning structure is used to place the deep probe fixing assembly and the deep probe into a deep soil detection hole. Both the shallow and deep probes include temperature detection probes, humidity detection probes, and salinity detection probes.

[0006] Furthermore, the shallow probe fixing assembly includes a fixing connecting ring, fixing claws, connecting rods, and a thrust elastic element. The fixing connecting ring is horizontally sleeved on the outside of the shallow probe. Multiple fixing claws are sequentially hinged around the outside of the fixing connecting ring. The fixing claws can rotate in a vertical plane. The fixing claws are used to fix the shallow probe by extending outward to abut against or insert into the hole wall of the probe hole. An annular groove is formed on the fixing connecting ring. Multiple grooves are uniformly and vertically formed along the radial direction on the inner side of the fixing connecting ring, and the lower ends of the grooves are connected to the annular grooves. A movable connecting ring is horizontally arranged inside the annular groove. The movable connecting ring can move up and down along the annular groove. A thrust elastic element is arranged inside the closed section at the top of the groove. Multiple connecting rods are sequentially hinged around the outside of the movable connecting ring. The lower ends of the connecting rods are hinged to the fixing claws. The fixed claws and connecting rods are located in the same vertical plane. A thrust elastic element is fixedly arranged on the inner wall of the groove. The thrust elastic element is used to push the movable connecting ring down to reset, and then push the fixing claws outward through the connecting rods.

[0007] Furthermore, the number of fixing claws is 3-6.

[0008] Furthermore, the deep probe fixing assembly includes a housing, a partition, a battery, and a cover. Multiple deep probes are evenly and horizontally arranged radially at the bottom of the housing cavity. The pins of the multiple deep probes penetrate the housing horizontally in different directions. Multiple partitions for sealing the housing cross-section are provided on the inner side of the housing. The multiple partitions divide the housing cavity into a detection cavity and a battery cavity. The deep probes are located inside the detection cavity. A battery is provided inside the battery cavity. The end of the housing near the battery cavity is an open end and is detachably connected to a cover.

[0009] Furthermore, the probe depth positioning structure includes a support, a reel, a meter counter, and a handle. The reel is rotatably mounted on the support, and the reel's shaft is horizontally positioned. One end of the reel's shaft is fixedly connected to the rotating end of the meter counter, and the other end of the reel's shaft is provided with a handle. A thin rope is wound on the reel, and the movable end of the thin rope is fixedly connected to a cover. When the housing is placed in the probe hole, rotating the handle can drive the reel to rotate, thereby releasing the thin rope and causing the housing to descend. The distance the thin rope is released is the height the housing descends. The meter counter is used to determine the distance the housing descends by recording the distance the thin rope is released.

[0010] Compared with the prior art, the present invention, by adopting the above technical solution, has the following advantages: This invention addresses the problem of probes being easily moved and affecting test results during shallow soil testing due to the lack of a fixed structure. It incorporates a shallow probe fixing component to secure the probe when inserted into the soil detection hole, ensuring testing accuracy. For deeper soil testing, existing technologies require multiple testing devices at different soil layers, leading to a high probability of failure. This device features a deep probe fixing component to protect the deep probe, reducing the number of testing devices and lowering the probability of failure. The probe depth positioning structure of the deep probe fixing component, through components such as a reel and a meter counter, accurately determines the descent distance of the housing, thereby precisely determining the deep probe detection depth. This facilitates deep soil testing operations and enables the detection of soil temperature, humidity, and salinity at multiple depths.

[0011] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Attached Figure Description

[0016] like Figure 1-9 As shown, a soil temperature, humidity and salinity detection device includes a detector body 1, a shallow probe 2, a deep probe 3, a shallow probe fixing component 4, a deep probe fixing component 5, and a probe depth positioning structure 6. The shallow probe fixing component 4 is fixedly disposed on the outside of the shallow probe 2 and is used to fix the shallow probe 2 in the shallow soil detection hole. The deep probe fixing component 5 is used to fix the deep probe 3. The probe depth positioning structure 6 is used to place the deep probe fixing component 5 and the deep probe 3 into the deep soil detection hole. Both the shallow probe 2 and the deep probe 3 include a temperature detection probe, a humidity detection probe, and a salinity detection probe.

[0017] Specifically, the detector body 1 is model TZS-ECW, and both the shallow probe 2 and the deep probe 3 detect the temperature, humidity and salinity in the soil by reflecting electromagnetic waves.

[0018] In one embodiment, the shallow probe fixing assembly 4 includes a fixing connecting ring 401, fixing claws 402, a connecting rod 403, and a thrust elastic element 404. The fixing connecting ring 401 is horizontally sleeved on the outside of the shallow probe 2. Multiple fixing claws 402 are sequentially hinged around the outer edge of the fixing connecting ring 401. The fixing claws 402 are rotatable in a vertical plane. The fixing claws 402 are used to fix the shallow probe 2 by extending outward to abut against or insert into the wall of the probe hole. An annular groove 405 is formed on the fixing connecting ring 401. Multiple grooves, each with its lower end communicating with the annular groove 405, are uniformly and vertically formed radially on the inner side of the fixing connecting ring 401. 406. A movable connecting ring 407 is horizontally arranged inside the annular groove 405. The movable connecting ring 407 can move up and down along the annular groove 405. A thrust elastic element 404 is arranged inside the closed section at the top of the groove 406. Multiple connecting rods 403 are sequentially hinged around the outer side of the movable connecting ring 407. The lower end of the connecting rod 403 is hinged to the fixed claw 402. The fixed claw 402 and the connecting rod 403 are located in the same vertical plane. A thrust elastic element 404 is fixedly arranged on the inner wall of the groove 406. The thrust elastic element 404 is used to push the movable connecting ring 407 down to reset, and then push the fixed claw 402 outward through the connecting rod 403.

[0019] Specifically, in the initial state, the limiting rope is wrapped around the outside of the multiple fixed claws 402 to tighten them. When the fixed claws 402 are tightened, the thrust elastic element 404 is in a compressed state. The thrust elastic element 404 is a spring. After the limiting rope is removed, the thrust elastic element 404 pushes the movable connecting ring 407 down to make the fixed claws 402 expand outward. The shallow probe 2 is connected to the detector body 1 through a data cable. The outside of the multiple fixed claws 402 is covered with an elastic membrane. The elastic membrane is used to avoid excessive pressure on the palm when holding the fixed claws 402, which may cause hand injury.

[0020] In one embodiment, the number of fixing claws 402 is 3-6.

[0021] In one embodiment, the deep probe fixing assembly 5 includes a housing 501, a partition 502, a battery 503, and a cover 504. Multiple deep probes 3 are uniformly and horizontally arranged radially at the bottom of the inner cavity of the housing 501. The pins of the multiple deep probes 3 horizontally penetrate the housing 501 in different directions. Multiple partitions 502 are provided inside the housing 501 to close its cross-section. The partitions 502 divide the inner cavity of the housing 501 into a detection cavity and a battery cavity. The deep probes 3 are located inside the detection cavity, and the battery 503 is located inside the battery cavity. The end of the housing 501 near the battery cavity is an open end and is detachably connected to the cover 504.

[0022] Specifically, the diameter of the housing 501 is approximately the same as the diameter of the deep probe hole. The total length of the housing 501 is 10cm. The open end of the housing 501 is provided with a charging port and a data cable connection port. The data cable connection port is connected to multiple deep probes 3 through wires. The cover 504 is provided with a through hole for the data cable to pass through. The detector body 1 is connected to the probes through the data cable. The cover 504 is snapped onto the housing 501 or connected by a latch.

[0023] In one embodiment, the probe depth positioning structure 6 includes a support 601, a reel 602, a meter counter 603, and a handle 604. The reel 602 is rotatably mounted on the support 601. The shaft of the reel 602 is horizontally positioned. One end of the shaft is fixedly connected to the rotating end of the meter counter 603, and the other end of the shaft is provided with a handle 604. A thin rope is wound on the reel 602, and the movable end of the rope is fixedly connected to the cover 504. When the housing 501 is placed in the probe hole, rotating the handle 604 can drive the reel 602 to rotate, thereby releasing the rope and causing the housing 501 to descend. The distance the rope is released is the height the housing 501 descends. The meter counter 603 is used to determine the distance the housing 501 descends by recording the distance the rope is released.

[0024] Specifically, the base plate of the support 601 has a through hole for the thin rope to pass through. The size of the through hole is similar to that of the detection hole. During testing, the support 601 is placed on the detection hole so that the through hole and the detection hole are roughly aligned. A damping shaft is provided at the rotation connection between the support 601 and the shaft of the reel 602. The damping shaft is used to limit the rotation of the handle 604. The support 601, reel 602 and handle 604 are made of lightweight plastic to reduce the carrying weight. The meter counter 603 is an electronic meter counter, model JK86.

[0025] The working process of this utility model is as follows: Shallow probe detection process: First, shallow soil detection holes are drilled in the soil. The shallow probe fixing assembly 4 is horizontally fitted onto the outside of the shallow probe 2. The fixing claw 402 is held in a retracted state, facilitating insertion into the soil detection hole. The assembled shallow probe 2 is inserted into the pre-dug soil detection hole. The thrust elastic element 404 pushes the movable connecting ring 407 downward. The movable connecting ring 407, through the connecting rod 403, pushes the fixing claw 402 outward, so that the fixing claw 402 contacts the hole wall, thereby fixing the shallow probe 2 in the detection hole. The shallow probe 2 transmits data back to the detector body 1. After the detection is completed, the outside of the multiple fixing claws 402 is held, and the shallow probe 2 is pulled upward to remove it from the detection hole. The fixing claws 402 are then secured by a fixing rope wrapped around their outside, completing the detection process.

[0026] Deep probe detection process: First, a deep soil detection hole is drilled in the soil. One end of the data cable is connected to the main body 1 of the detector, and the other end is connected to the data cable connector through the cover 504. Then, the cover 504 is closed, and the housing 501 is vertically placed into the detection hole. The upper surface of the cover 504 is adjusted to be approximately flush with the base plate of the support 601. The electronic meter counter 603 is reset to zero. Then, the handle 604 is rotated to make the reel 602 rotate and release the thin rope. The electronic meter counter 603 records the length of the released rope and adds it to the length of the housing 501. The depth is the descent depth of the bottom of the housing 501. After reaching the specified depth, the rotation of the handle 604 is stopped. The handle 604 is fixed by the damping shaft. Multiple deep probes 3 detect the soil temperature, humidity and salinity respectively. After detecting one depth, the handle 604 is rotated to lower the housing 501 to the second detection depth. After all detection depths are detected, the handle 604 is rotated in the opposite direction to move the housing 501 upward. Then the support 601 is removed from the detection hole, the housing 501 is taken out, and the detection process is completed.
