[0033] In the above embodiments, it should be noted that motor 13 is a DC brushless motor;

[0034] The technical effects achieved by the above embodiments are as follows: the auger bit 11 is shaped like a geological hammer tip, enhancing the device's soil-breaking ability and enabling it to drill efficiently even in fractured rock layers or hard sedimentary layers; the hammer tip has a built-in micro vibration sensor, which can analyze soil density or rock fracture development by striking the strata; a micro soil sampler is integrated on the side of the probe head body 1 to collect soil samples during drilling, and can quickly analyze soil mineral composition with the help of a spectrometer; the auger bit 11 uses a diamond-tungsten carbide composite drill bit, which effectively adapts to mixed rock and soil strata, significantly reduces drill bit wear, and improves the service life of the device; by combining pressure sensor and vibration frequency data, a stratum type identification model is established, and the system automatically adjusts the drilling speed and torque to avoid jamming and ensure stable operation of the device in complex strata.

[0035] Example 3

[0036] like Figures 1 to 8 As shown, a biomimetic earthworm detection device includes all the contents of Embodiment 2. In addition, a connecting sleeve 3 is fixedly connected to the other side of the inner wall of the first connecting sleeve 41. There are multiple sleeves 3. A second connecting sleeve 42 is provided between two connected sleeves 3 and connected together by the first connecting sleeve 41. The first connecting sleeve 41 and the second connecting sleeve 42 are made of rubber.

[0037] In the above embodiments, it should be noted that the first connecting sleeve 41 and the second connecting sleeve 42 are made of rubber, enabling them to twist and turn. Two sleeves 3 are fixedly connected to both ends of the inner wall of the second connecting sleeve 42. The second connecting sleeve 42 is provided with a connecting part 421 and a twisting part 422. A turning part 423 is provided inside the second connecting sleeve 42. The twisting part 422 has a corrugated structure and can twist and deform. The turning part includes a mounting base 4231, a connecting sleeve 4232, and a telescopic rod 4233. There are four sets of mounting bases 4231, connecting sleeves 4232, and telescopic rods 4233, all located in the second connecting sleeve 42. The inner walls of the connecting sleeve 42 are fixedly mounted on the two sides of the inner wall of the second connecting sleeve 42. The two mounting seats 4231 are fixedly mounted on the inner sides of the connecting parts 421 on both sides. The inner walls of the upper and lower sides of the mounting seat 4231 are provided with sliding grooves. The connecting sleeve 4232 is slidably mounted on the inner wall of the mounting seat 4231. The two sides of the connecting sleeve 4232 can rotate on the inner wall of the mounting seat 4231. The two ends of the outer wall of the telescopic rod 4233 are fixedly connected to the two connecting sleeves 4232 respectively. The outer side of the inner wall of the second connecting sleeve 42 is fixedly connected to the sleeves on the adjacent sides. The sleeves and the turning part do not interfere with each other. The first connecting sleeve 41 and the second connecting sleeve 42 have the same structure.

[0038] The technical effect achieved by the above embodiment is as follows: when the four sets of telescopic rods 4233 on the inner wall of the turning part 423 begin to retract or extend respectively, the connecting sleeve 4232 slides and rotates on the inner wall of the mounting base 4231 to adapt to the length change of the telescopic rods 4233. At the same time, when the telescopic rods 4233 retract or extend, the twisting part 422 inside the second connecting sleeve 42 can twist according to the different lengths of the four telescopic rods 4233, thereby controlling the sleeve 3 to turn. The first connecting sleeve 41 and the second connecting sleeve 42 can twist and turn, so that the probe body 1 and the sleeve 3 can turn.

[0039] Example 4

[0040] like Figures 1 to 8 As shown, a biomimetic earthworm detection device includes all the contents of Embodiment 3. In addition, the detection component is disposed on the inner wall of the detection head body 1. The detection component also includes a multi-parameter water quality detection probe 22. The pressure sensor 21 is electrically connected to the main control board 2. The multi-parameter water quality detection probe 22 is electrically connected to the main control board 2. The position sensor 23 is electrically connected to the main control board 2.

[0041] In the above embodiment, it should be noted that: at this time; multi-parameter water quality detection probes are arranged on both sides of the probe body 1. The detection probes have built-in multi-parameter sensor arrays, including water level sensors, pH sensors, dissolved oxygen sensors, conductivity sensors, turbidity sensors, etc., which can monitor groundwater level and various key water quality parameters in real time and accurately, as shown in the table below; position sensor 23 is fixedly installed on the main control board 2. Position sensor 23 is a three-dimensional position sensor that can transmit the device's burial depth, location data, and water quality data detected by the multi-parameter water quality probes back to the main control board; the working principle of the turbidity sensor is mainly based on optical principles; when a light beam enters the water sample, suspended particles in the water will cause light scattering; the sensor calculates the turbidity of the water sample by measuring the intensity of scattered light in the direction perpendicular to the incident light; specifically, the light source emits 860nm infrared light, the sensor detects the intensity of scattered light in the 90° direction, and calculates the turbidity based on the detected scattered light intensity; in addition, the infrared pair tube inside the sensor will judge the turbidity of the water based on the light transmittance and scattering rate. The more turbid the water, the less light is transmitted, and the output current signal is also reduced accordingly.

[0042]

[0043]

[0044] The technical effects achieved by the above embodiments are as follows: when the pressure sensor 21 detects that the water pressure has reached the set threshold, it indicates that the area contains groundwater, and the device is stopped by the control board 2; the pH value, dissolved oxygen, oxidation-reduction potential and turbidity of the groundwater are detected by the multi-parameter water quality detection probe 22, and the detection results are fed back to the control board 2. If the water quality is poor, the control board 2 controls the device to stop moving forward and purifies the groundwater by the purification component.

[0045] Example 5

[0046] like Figures 1 to 8 As shown, a biomimetic earthworm detection device includes all the contents of Embodiment 4. In addition, the purification component also includes a first guide hole 301. A plurality of first guide holes 301 are opened on the inner side of the outer wall of the sleeve 3. The first guide hole 301 has a conical cross section. The activated carbon adsorption layer 51 is disposed on the inner wall of the sleeve 3. An ion exchange membrane 52 is disposed on the outer wall of the activated carbon adsorption layer 51.

[0047] In the above embodiments, it should be noted that the first guide hole 301 is a conical hole, and the activated carbon adsorption layer 51 is fixedly installed on the inner wall of the sleeve 3. Activated carbon is made by activating carbon-containing materials such as wood, coal, and fruit shells under high temperature and oxygen-deficient conditions. Activated carbon adsorption is a water treatment method that utilizes the physical adsorption, chemical adsorption, oxidation, catalytic oxidation, and reduction properties of activated carbon to remove pollutants from water. The working principle of ion exchange membranes is based on the charge characteristics of ions in solution. Ion exchange membranes are usually made of polymer materials and contain functional groups that can react with ions in water. These functional groups can selectively adsorb and transport specific types of ions (cations or anions), thereby achieving ion separation and concentration. Ion exchange membranes are widely used in water treatment and other fields.

[0048] The technical effect achieved by the above embodiment is as follows: groundwater can be introduced into the inner wall of the sleeve 3 through the first guide hole 301, and the water quality can be purified by the ion exchange membrane 52 and activated carbon adsorption layer 51 on the inner wall of the sleeve 3, effectively removing Ca2+. + Mg2 + As3 + Cu 2 + metal ions, reduce turbidity, conductivity, etc.

[0049] Example 6

[0050] like Figures 1 to 8 As shown, a biomimetic earthworm detection device includes all the contents of Embodiment 5. In addition, one end of the sleeve 3 is connected to a flow guide block 31, the inner wall of the flow guide block 31 is provided with a second flow guide hole, the flow guide block 31 is conical, and the flow guide block 31 is embedded in the inner wall of the adjacent sleeve 3.

[0051] In the above embodiments, it should be noted that a spring 5 is provided on the inner wall of the sleeve 3, and one end of the guide block 31 is fixedly connected to the sleeve 3 through a rubber hose. The guide block 31 is conical, and one end of the tip of the guide block 31 can be inserted into the inner wall of the adjacent sleeve 3 and is located on the inner wall of the activated carbon adsorption layer 51. At the same time, a spring 5 is provided on the inner wall of each sleeve 3. One end of the spring 5 on the left side is fixedly connected to the probe body 1, and the other end is fixedly connected to the inner wall of the guide block 31 adjacent to the spring 5. The two ends of the springs 5 ​​on the inner walls of other sleeves 3 are respectively connected to two adjacent guide blocks 31.

[0052] The technical effect achieved by the above embodiment is that the guide block 31 can be twisted, and the guide block 31 is embedded in the inner wall of the adjacent sleeve 3 and fixedly connected to it, without affecting the twisting direction of the second connecting block 42, so that the sleeves 3 can twist.

[0053] Working Principle: During operation, the main control board 2 controls the motor 13 to start, driving the auger drill bit 11 to rotate and excavate underground. As the equipment moves forward, the pressure sensor 21 detects the water pressure and sends the result back to the main control board 2. When the water pressure exceeds a threshold, the main control board 2 stops the equipment in place. The position sensor 23 transmits the equipment's position to the main control board 2. The multi-parameter water quality probe 22 detects the pH value, dissolved oxygen, oxidation-reduction potential, and turbidity of the groundwater, and the main control board 2 transmits the results. The location of the equipment is transmitted to the terminal equipment. If the water quality is poor, the main control board 2 controls the equipment to stop moving forward. The groundwater enters the sleeve 3 through the first guide hole 301. The groundwater passes through the ion exchange membrane 52 and the activated carbon adsorption layer 51. The groundwater is adsorbed and purified by the ion exchange membrane 52 and the activated carbon adsorption layer 51. The purified groundwater flows into the adjacent sleeve 3 through the guide block 31 and is discharged through the guide block 31 on the outside of the last sleeve 3. During the movement of the equipment, the first connecting sleeve 41 and the second connecting sleeve 42 can bend, so that the equipment can turn as a whole.
