DETAILED DESCRIPTION

[0051] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0052] like Figures 1 to 6 As shown:

[0053] Embodiment 1: The present invention provides a hydrogeological exploration device, comprising a driving mechanism 1 and an exploration mechanism 2:

[0054] The driving mechanism 1 comprises a sleeve assembly 11, a rotating rod assembly 12 is rotatably embedded in the sleeve assembly 11, and a driving assembly 13 is also mounted on the sleeve assembly 11;

[0055] The exploration mechanism 2 includes a drill assembly 21 rotatably embedded in the bottom of the sleeve assembly 11, and a plurality of sampling assemblies 22 are embedded inside the drill assembly 21;

[0056] The sleeve assembly 11 includes a sleeve body 111 , and a mounting plate 112 is fixedly connected to the upper end of the sleeve body 111 ;

[0057] The rotating rod assembly 12 includes a connecting rod 121, the upper end of the connecting rod 121 is fixedly connected to a belt 122, and the lower end of the connecting rod 121 is fixedly connected to a square block 123;

[0058] The driving assembly 13 includes a motor 131, and a belt 2 132 is fixedly connected to the output end of the motor 131;

[0059] The connecting rod 121 is installed inside the sleeve body 111 through a bearing, the motor 131 is fixedly installed on the mounting plate 112, and the outer sides of the belt 2 132 and the belt 1 122 are jointly sleeved with a belt;

[0060] The drill bit assembly 21 includes an exploration tube 211, a drill bit body 212 is fixedly connected to the bottom of the exploration tube 211, a threaded joint 213 is fixedly connected to the upper end of the exploration tube 211, and a plurality of guide grooves 214 are provided on the outer side of the exploration tube 211;

[0061] The sampling assembly 22 includes an arc-shaped push block 221 and a guide plate 222. A sampling column 223 is fixedly connected to one end of the arc-shaped push block 221, and a plurality of springs 224 are fixedly connected to the outer side of the guide plate 222.

[0062] The arc-shaped push block 221 and the guide plate 222 are both slidably embedded in the guide groove 214, and the spring 224 drives the guide plate 222 to push the arc-shaped push block 221 to embed into the interior of the exploration tube 211;

[0063] The threaded connector 213 is rotatably embedded in the bottom of the sleeve body 111 , and the square block 123 is slidably embedded in the inside of the exploration tube 211 . The square block 123 can drive the arc-shaped push block 1 221 to drive the sampling column 223 to extend out of the exploration tube 211 and compress the spring 2 234 .

[0064] As can be seen from the above, when in use, the sleeve body 111 is moved downward so that the drill bit body 212 is embedded in the soil. After reaching the specified depth:

[0065] The motor (131) is started, and the output shaft of the motor (131) starts to rotate, driving the second belt (132) to rotate. Since the second belt (132) and the first belt (122) are connected by a belt, the first belt (122) will also rotate accordingly;

[0066] The rotation of the belt 1 (122) drives the rotation of the connecting rod (121), and the connecting rod (121) is installed inside the sleeve body (111) through a bearing, so that the connecting rod (121) can rotate smoothly inside the sleeve body (111), and the square block (123) at the lower end of the connecting rod (121) will also rotate accordingly;

[0067] The square block (123) is slidably embedded in the inside of the exploration tube (211). As the connecting rod (121) rotates, the square block (123) rotates accordingly. At the same time, the square block (123) contacts the arc-shaped push block 1 (221) and pushes it to move along the guide groove 1 (214).

[0068] Under the push of the square block (123), the arc-shaped push block (221) overcomes the elastic force of the spring (224), driving the sampling column (223) to extend from the side wall of the exploration tube (211) and insert into the soil. As the square block (123) continues to move, the sampling column (223) will embed part of the soil sample and bring it back, thereby completing the sampling process.

[0069] Ending the exploration: After collecting the soil sample, the motor (131) is turned off to stop the rotation; then, the exploration mechanism (2) is pulled out from the soil by lifting the sleeve body (111), thus completing the exploration process;

[0070] Collecting samples: Finally, rotating the exploration tube (211) can cause the threaded joint 213 to be separated from the bottom of the sleeve body (111), thereby removing the drill bit assembly 21, and then conveniently taking out the collected soil samples for subsequent analysis and research.

[0071] like Figure 7 and Figure 8 As shown:

[0072] Embodiment 2: This embodiment is basically the same as the previous embodiment, except that a handle 113 is fixedly connected to the upper end of the outer side of the sleeve body 111 ; the handle 113 can facilitate the staff to drive the sleeve body 111 to move downward.

[0073] Specifically, a push ring 225 is slidably connected to the interior of the sampling column 223, and a push rod 226 is fixedly connected to one end of the push ring 225;

[0074] A through slot is formed in the middle of the arc-shaped push block 1 221 .

[0075] Specifically, a plurality of detection components 23 are embedded inside the drill assembly 21;

[0076] The square block 123 can drive a plurality of detection components 23 to extend out of the exploration tube 211 .

[0077] Specifically, the detection assembly 23 includes an arc-shaped push block 231 and a guide plate 232. One end of the arc-shaped push block 231 is fixedly connected to a sensor 233, and one end of the guide plate 232 is fixedly connected to a set of springs 234.

[0078] The outer side of the exploration tube 211 is also provided with a plurality of guide grooves 215;

[0079] The second arc-shaped push block 231 and the second guide plate 232 are both slidably embedded in the second guide groove 215 , and the second spring 234 drives the second guide plate 232 to push the second arc-shaped push block 231 to drive the sensor 233 to be embedded in the inside of the exploration pipe 211 .

[0080] like Fig. 9 As shown:

[0081] Specifically, a guide mechanism 3 is also installed on the outer side of the sleeve assembly 11;

[0082] The guide mechanism 3 includes a guide column 31;

[0083] The sleeve assembly 11 is slidably engaged on the guide post 31 .

[0084] Specifically, a plurality of connecting plates 32 are fixedly connected to the outer side of the guide column 31, and a base 33 is fixedly connected to the lower side of the end of the connecting plate 32;

[0085] Among them, after the guide mechanism 3 is installed on the outside of the sleeve assembly 11, the guide column 31 can play a guiding role, ensuring that the sleeve assembly moves smoothly and accurately in the vertical or specific direction, avoiding deviation or shaking, thereby improving the efficiency and accuracy of the exploration operation. At the same time, the addition of the base 33 and the connecting plate 32 makes the entire exploration device more stable, able to withstand greater external forces, and ensures the safety of the exploration operation.

[0086] As can be seen from the above, when the square block (123) rotates, the arc-shaped push block 231 is also pushed, so that the sensor 233 penetrates the guide groove 215 and then embeds into the soil, thereby surveying the soil condition;

[0087] When the arc-shaped push block 231 is pushed, the guide plate 232 will squeeze the spring 234. When the arc-shaped push block 231 is no longer pushed, the spring 234 will reset, causing the guide plate 232 to drive the arc-shaped push block 231 to reset, thereby retracting the sensor 233.

[0088] Sensors 233 include, but are not limited to, using temperature sensors, humidity sensors, pH sensors, conductivity sensors, soil moisture sensors, and soil compaction sensors.

[0089] Embodiment 3: A prospecting method, comprising the above-mentioned hydrogeological prospecting device, further comprising the following steps:

[0090] Step a: placing the exploration device at the geological location to be explored;

[0091] Step b: moving the sleeve assembly 11 downward to embed the drill bit body 212 of the drill bit assembly 21 into the soil until reaching a designated exploration depth;

[0092] Step c: starting the motor 131 in the driving assembly 13, the motor 131 drives the rotating rod assembly 12 to rotate through the belt transmission, and then drives the square block 123 to rotate in the exploration tube 211;

[0093] Step d: During the rotation process, the square block 123 pushes the arc-shaped push block 1 221 of each sampling assembly 22, so that the sampling column 223 extends from the side wall of the exploration tube 211 and is inserted into the soil for sampling. After the sampling is completed, the sampling column 223 is reset under the action of the spring 1 224;

[0094] Step e: After collecting the soil sample and completing the geological parameter detection, turn off the motor 131 and stop rotating;

[0095] Step g: The exploration mechanism 2 is pulled out of the soil by lifting the sleeve assembly 11, and the threaded joint 213 of the exploration pipe 211 is rotated to separate it from the bottom of the sleeve body 111, thereby removing the drill bit assembly 21;

[0096] Step h: Take out the soil sample in the sampling column 223.
