Description

Technical Field

[0001] This invention relates to the field of detection equipment technology, and in particular to a soil moisture detection device and method for loess areas with a moisture-sensitive sensor. Background Technology

[0002] A humidity sensor, also known as a moisture sensor, is a sensing element that can sense the humidity of the external environment and convert it into a measurable electrical signal. The soil moisture detection device in the Loess Plateau is a device for monitoring the soil moisture content in the Loess Plateau region. It can achieve real-time and accurate detection of soil moisture and provide data support for ecological management, agricultural irrigation and geological disaster early warning.

[0003] According to the soil moisture detector disclosed in application number CN202222219202.8, which relates to the field of moisture detection, this invention addresses the problem that existing soil moisture detectors tend to accumulate a lot of soil after detection and lack a structure to assist in cleaning the soil. The invention includes a collection component, which is a rectangular tubular structure installed at the bottom of the main body. A detection rod runs through the inside of the collection component, and a cleaning component, which is annular in shape with an inclined outer side, is located at the bottom of the collection component. The cleaning component is made of rubber. During use, as the moving component moves downwards, an auxiliary groove allows the auxiliary component to adapt and deform, facilitating its passage through the soil. Soil follows the detection rod into the collection component, where it enters. The cleaning component then moves rapidly outside the detection rod, scraping away the soil and allowing for quick removal, thus enabling easy cleaning of the detection rod.

[0004] However, in the use of existing soil moisture detection devices in the Loess region with moisture-sensitive sensors, when the socket for connecting the sensor is not occupied, dust and foreign objects are easily allowed to enter the socket, causing poor contact or short circuit, which in turn affects the normal operation of the equipment and its service life.

[0015] Furthermore, the method of using the aforementioned soil moisture detection device with a humidity sensor in the loess region is characterized by:

[0016] 1. Preparation for use:

[0017] Pull the power supply solar panel out from the rear of the testing unit and unfold it with the support of the connecting folding rod. During the unfolding process, the positioning balls at both ends of the connecting folding rod will automatically lock into the positioning grooves on the testing unit and the solar panel bracket under the action of the positioning compression spring, thereby fixing the angle and position. At this time, the solar panel will convert light energy into electrical energy to power the internal circuit of the testing unit or charge the built-in battery, thus extending the battery life.

[0018] 2. Sensor Connection:

[0019] Insert the second detection transmission wire into the connection socket at the lower end of the detection body. The humidity sensor at the lower end of the second detection transmission wire can be inserted into the soil to detect the soil moisture in the Loess region in real time. Insert the first detection transmission wire into another connection socket. The light intensity sensor at the lower end of the first detection transmission wire can monitor the ambient light intensity and assist in the analysis of environmental factors affecting soil moisture changes. When the first or second detection transmission wire is not inserted into the connection socket, the protective hinge plate automatically closes under the action of the closed torsion spring, closing the connection socket and preventing dust or foreign objects from entering.

[0020] 3. Equipment installation:

[0021] Insert the wooden pole into the ground as a fixed support for the testing device. Wrap two hinged clamping plates around the outside of the wooden pole. By connecting the fastening threaded rod to the inside of the hinged connecting plate and tightening the fastening nut, the hinged connecting plate is tightened, thus firmly clamping the hinged clamping plate onto the wooden pole. Then loosen the fastening threaded parts and adjust the tilt angle of the testing machine body by adjusting the rotation of the mounting ball in the fixed threaded sleeve to facilitate operation or light reception. After adjustment, tighten the fastening threaded parts. The inner inclined surface of the fastening threaded parts presses against the fixed threaded sleeve, causing the fixed threaded sleeve to clamp the adjusting mounting ball, thus achieving a stable lock of the angle of the testing machine body.

[0022] 4. Display screen maintenance:

[0023] Press the limit slider to disengage it from the mounting limit groove inside the testing machine body. Simultaneously, compress the limit spring to lift and pull out the detachable display screen for easy replacement or maintenance. Align the limit groove at the top of the detachable display screen with the limit protrusion at the front of the testing machine body and insert it. Press down on the detachable display screen so that the limit slider automatically engages with the mounting limit groove under the action of the limit spring, thus completing the locking.

[0024] 5. Equipment protection:

[0025] A transparent protective cover is used to cover the front of the testing unit. It can be flipped open and closed to prevent the display screen from being scratched or corroded by rain. At the same time, the information displayed on the detachable display screen can be viewed through the transparent protective cover. When the connection hole is not in use, the protective hinge plate automatically closes the connection hole, and works with the sealing torsion spring to achieve a sealing protection, improving the durability of the equipment in the field environment.

[0026] This invention provides a soil moisture detection device and method for loess areas with a moisture-sensitive sensor, which has the following beneficial effects:

[0027] This invention utilizes a folding mechanism to achieve the folding and unfolding functions of the power supply solar panel. In use, the power supply solar panel is pulled out of the detection unit and supported by a connecting folding rod. During this process, a positioning ball automatically engages with the positioning groove under the action of a positioning compression spring, thus fixing the position and angle of the connecting folding rod and the power supply solar panel. After unfolding, the power supply solar panel converts solar energy into electrical energy to power or charge the detection unit. When not in use, the solar panel can be folded up, effectively reducing the overall size of the equipment and facilitating portability and storage.

[0028] Furthermore, the installation mechanism facilitates convenient installation and removal between the testing unit and the detachable display screen. When the display screen needs to be replaced or maintained, simply push and press the limit slider to disengage it from the installation limit groove, allowing the detachable display screen to be lifted and removed. The operation is simple. In field installation, a wooden pole can be inserted into the ground for support. Then, the hinged clamping plate is wrapped around the outside of the wooden pole, and the threaded rod is connected and tightened through the notch of the hinged connecting plate. The tightening nut is then tightened, and the linkage structure tightens the hinged clamping plate and firmly clamps it onto the wooden pole. The threaded fastener is then loosened, and the tilt angle of the testing unit is adjusted by adjusting the mounting ball. Once the angle is appropriate, the threaded fastener is tightened again. Its inclined structure will compress the fixing threaded sleeve, thereby locking the adjusting mounting ball and achieving stable fixation of the testing unit. This structure is not only flexible in installation and easy to maintain, but also supports the individual replacement of the detachable display screen, significantly reducing the maintenance cost of the equipment.

[0029] Furthermore, the protective mechanism effectively enhances the durability and reliability of the equipment. The transparent protective cover is hinged to the front of the testing machine and can be closed when not in use, providing dustproof, scratch-proof, and waterproof protection for the detachable display screen. At the same time, a protective hinge plate is installed inside the connection socket. When the first or second detection transmission wire is not inserted, the protective hinge plate automatically closes under the action of the closed torsion spring, sealing the connection socket and preventing dust or impurities from entering. This avoids poor contact or circuit failure, thereby extending the service life of the equipment and reducing maintenance frequency and economic losses.

[0030] Furthermore, the aforementioned mechanism not only enables convenient deployment and storage of the power supply solar panels, improving portability, but also facilitates stable installation of the testing unit and quick replacement of the display screen, enhancing maintenance efficiency. Simultaneously, it effectively protects the connection sockets and display screen, strengthening the equipment's adaptability to the complex environment of the loess region and its long-term operational stability.

7. The method of using the soil moisture detection device with a moisture-sensitive sensor in the loess region as described in claim 1, characterized in that:

1. Preparation for use: Pull the power supply solar panel out from the rear of the detection unit and unfold it with the support of the connecting folding rod. During the unfolding process, the positioning balls at both ends of the connecting folding rod will automatically lock into the positioning grooves on the detection unit and the solar panel bracket under the action of the positioning compression spring, so as to fix the angle and position. At this time, the solar panel will convert light energy into electrical energy to power the internal circuit of the detection unit or charge the built-in battery and extend the battery life.

2. Sensor Connection: Insert the second detection transmission wire into the connection socket at the lower end of the detection body. The humidity sensor at the lower end of the second detection transmission wire can be inserted into the soil to detect the soil moisture in the Loess region in real time. Insert the first detection transmission wire into another connection socket. The light intensity sensor at the lower end of the first detection transmission wire can monitor the ambient light intensity and assist in the analysis of environmental factors affecting soil moisture changes. When the first or second detection transmission wire is not inserted into the connection socket, the protective hinge plate automatically closes under the action of the closed torsion spring, closing the connection socket and preventing dust or foreign objects from entering.

3. Equipment installation: Insert the wooden pole into the ground as a fixed support for the detection device. Wrap two hinged clamping plates around the outside of the wooden pole. By connecting the fastening threaded rod to the inside of the hinged connecting plate and tightening the fastening nut, the hinged connecting plate is tightened, thus firmly clamping the hinged clamping plate onto the wooden pole. Then loosen the fastening thread and adjust the tilt angle of the detection body by adjusting the rotation of the mounting ball in the fixed threaded sleeve to facilitate operation or light reception. After adjustment, tighten the fastening thread. The inner inclined surface of the fastening thread presses against the fixed threaded sleeve, causing the fixed threaded sleeve to clamp the adjusting mounting ball, thus achieving a stable lock of the detection body angle.

4. Display screen maintenance: Press the limit slider to disengage it from the mounting limit groove inside the testing machine body. Simultaneously, compress the limit compression spring to lift and pull out the detachable display screen for easy replacement or maintenance. Align the limit groove at the top of the detachable display screen with the limit protrusion at the front of the testing machine body and insert it. Press down on the detachable display screen so that the limit slider automatically engages with the mounting limit groove under the action of the limit compression spring, thus completing the locking.

5. Equipment protection: A transparent protective cover is used to cover the front of the testing unit. It can be flipped open and closed to prevent the display screen from being scratched or corroded by rain. At the same time, the information displayed on the detachable display screen can be viewed through the transparent protective cover. When the connection hole is not in use, the protective hinge plate automatically closes the connection hole, and works with the sealing torsion spring to achieve a sealing protection, improving the durability of the equipment in the field environment.
