[0029] Among them, the surface of the cylinder is also provided with heat dissipation holes, which are located on the side of the power module for heat dissipation.

[0030] The cylinder is also provided with a transparent observation window with a scale for observing the movement of the pressure head; the sensor is also provided with a pointer, which is aligned with the scale of the observation window to directly read the distance the pressure head drops.

[0031] Working principle:

[0032] When soil strength testing is required, first ensure that the device is placed on the soil surface to be tested and that the chassis is stably supported on the ground;

[0033] Next, start the power module in the intelligent module to provide power support for the entire system; the power module is a rechargeable battery that can provide stable power for the electric telescopic cylinder, display screen and central control module;

[0034] Then, input the operation command through the key on the intelligent module to start the pressurizing mechanism to work; the electric telescopic cylinder, as the power source, starts working after receiving the command from the central control module; it is connected to the mounting rod through the bracket, and when the electric telescopic cylinder is extended, it pushes the mounting rod to move downward along the sliding rod; the other side of the mounting rod is slidably connected to the sliding rod through the sliding sleeve to ensure that the mounting rod can move up and down smoothly along the sliding rod;

[0035] A detachable pressure head is provided at the bottom of the mounting rod. The pressure head is designed in the shape of a round hammer and is suitable for a variety of soil types. When the mounting rod moves downward, the pressure head also moves downward and freely moves through the bottom of the cylinder to contact the soil and apply pressure.

[0036] During the process of the pressure head descending, the sensor is set on the surface of the sliding sleeve to detect the distance the pressure head descends in real time and send the distance signal to the central control module; at the same time, the electric telescopic cylinder will also feed back the pressurization pressure signal to the central control module;

[0037] After receiving these signals, the central control module uses the preset soil density database and built-in algorithms for calculation; these algorithms take into account factors such as soil density, moisture content, and particle size, and combine the distance the pressure head drops and the pressure signal to finally calculate the soil strength through a series of complex mathematical operations and logical judgments.

[0038] The calculation results are displayed on the display screen in the intelligent module. Users can directly read the information of soil strength, pressurization pressure, pressure head drop distance and power supply module power from the display screen. The display screen also provides an intuitive interface and interactive functions to facilitate users to set parameters and control operations.

[0039] In addition, in order to increase the intuitiveness and convenience of detection, a transparent observation window with a scale is provided on the cylinder; the user can directly observe the movement of the pressure head through the observation window, and a pointer is also provided on the sensor, which is aligned with the scale of the observation window, so that the user can directly read the distance the pressure head has dropped;

[0040] Finally, in order to ensure the stability and security of the system, the central control module is also equipped with a data storage module; during the detection process, all detection data and calculation results will be automatically saved in the data storage module to facilitate subsequent analysis and processing; at the same time, there are heat dissipation holes on the surface of the cylinder, located on the side of the power module, which are used to promptly dissipate the heat generated by the power module during operation to ensure the stable operation of the system;

[0041] In summary, the soil strength detection device for geological survey realizes the rapid and accurate detection of soil strength through the coordinated work of the pressurizing mechanism and the intelligent module, and provides intuitive and convenient display and interactive functions.

[0042] Example: Specific process of soil strength calculation

[0043] 1. Soil parameter input and preset database

[0044] Soil density database: A soil density database is preset in the device, which contains the corresponding relationship between different soil types, density, moisture content, particle size and other parameters and soil strength; these data are obtained through a large number of experiments and field measurements to ensure the accuracy of the calculation.

[0045] Real-time parameter input: During the detection process, the user can input soil density, moisture content, particle size and other parameters through the display screen of the smart module, or the device can automatically detect these parameters through sensors.

[0046] 2. Pressure head drop distance and pressurization pressure signal

[0047] Pressure head drop distance: The sensor monitors the pressure head drop distance in real time and sends the distance signal to the central control module; this distance reflects the soil's resistance to the pressure head and is one of the important parameters for calculating soil strength;

[0048] Pressurization pressure signal: When the electric telescopic cylinder pushes the pressure head down, it will feed back the pressurization pressure signal to the central control module; this pressure signal also reflects the soil's resistance to the pressure head and is another important calculation parameter.

[0049] 3. Algorithm Calculation Process

[0050] Data matching: The central control module first searches the soil density database for the corresponding soil strength range based on the input soil parameters (density, moisture content, particle size, etc.).

[0051] Weighting: Weights are assigned to different values ​​within the soil strength range based on factors such as soil density, moisture content, and particle size; density and moisture content generally have a greater impact on soil strength and are therefore assigned higher weights.

[0052] Mathematical operations: Based on the distance the pressure head drops and the pressurization pressure signal, the central control module performs a series of complex mathematical operations; these operations may include advanced algorithms such as linear regression, multivariate regression analysis, neural networks, etc. to accurately calculate the strength of the soil.

[0053] Logical judgment: During the calculation process, the central control module will also make judgments and adjustments based on preset logical rules; for example, if the pressure head drops too far or the pressurization pressure is too small, it may mean that the soil is soft. At this time, it is necessary to adjust the calculation parameters or use other algorithms for calculation.

[0054] Result output: The final calculated soil strength value is displayed on the display screen and the user can read it directly; at the same time, the central control module will also save the calculation results to the data storage module for subsequent analysis and processing.

[0055] IV. Precautions

[0056] Accuracy of soil parameters: The input soil parameters (density, moisture content, particle size, etc.) should be as accurate as possible to ensure the reliability of the calculation results.

[0057] Applicability of the algorithm: Different soil types and geological conditions may require different algorithms for calculation; therefore, in practical applications, the appropriate algorithm should be selected for calculation according to the specific situation.

[0058] Equipment calibration and maintenance: Regularly calibrate and maintain the device to ensure the normal operation of components such as sensors and electric telescopic cylinders to ensure the accuracy of test results.

[0059] The soil strength detection device for geological survey is suitable for the fields of geological survey, agricultural research, civil engineering and environmental monitoring, and is used for quickly and accurately detecting the strength of soil.

[0060] The utility model can also be provided with an overload protection mechanism and an overheat protection mechanism to ensure the safety and reliability of the device during use.

[0061] The surface of the cylinder body of the utility model can also be provided with a handle or a grip.

[0062] The bottom frame of the utility model can also be provided with supporting feet in contact with the ground to ensure the stability of the device during the detection process.

[0063] The medium pressure head of the utility model can also be in a cone shape, which can directly replace the round hammer shape and be used for breaking the ground on site, thereby increasing the versatility of the device.

[0064] The control method of the utility model is to control by manually starting and closing the switch. The wiring diagram of the power element and the provision of power supply belong to the common knowledge in the field, and the utility model is mainly used to protect the mechanical device, so the utility model will not explain the control method and wiring arrangement in detail;

[0065] Alternatively, the control method of the present invention is automatic control through a controller, the control circuit of the controller can be implemented by simple programming by technicians in this field, the provision of power is also common knowledge in this field, and the present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.
