[0022] An experimental method of a multifunctional experimental device for comprehensive determination of hydrogeological parameters

[0023] Step 1: First, carry the equipment to the test site, then place the equipment on the ground, and then turn the crank handle. When the crank handle turns, it will drive the insertion rod to rotate synchronously and then penetrate into the ground and fix it. Then connect the motor to an external power source. If used in the field, the equipment's own backup power supply can be used to supply power.

[0024] Step 2: After the motor is connected to the power supply, start the motor. After the motor starts, it controls the drill rod to rotate and penetrate deeper into the ground. When the drill rod reaches the specified depth, pull up the cross sleeve and lift the cross sleeve from the cross head. Then rotate the actuating block. After the cross sleeve is released, the second spring will press down on the cross sleeve and position the cross sleeve on the cross head. This will prevent the actuating block from rotating back.

[0025] Step 3: Rotate the actuating block, which drives the fixed column inside the drill rod to rotate by an angle through the connecting rod until the side groove overlaps with the positioning groove. Then, sensors with different detection functions are inserted from the top of the four side grooves in sequence.

[0026] Step 4: After the sensor enters from the side groove, it slides along the side groove and positioning groove to the bottom of the drill rod and then protrudes. This way, there is no need to retract the drill rod during testing. After multiple sets of sensors are placed, the end of the data cable is plugged into the data connector on the outside of the lifting platform. In this way, the data collected by the sensor is uploaded to the data receiver and then centrally processed and analyzed by the processor.

[0027] Step 5: After the experiment is completed, unplug the data cable, then retract the sensor, then use the motor to remove the drill rod from the ground, then remove the insertion rod from the ground, and finally hold the handles at both ends of the crossbar to carry the equipment.

[0028] Compared with the prior art, the beneficial effects of the present invention are:

[0029] 1. After the hole is opened, sensors with different detection functions are sequentially inserted from the top of the four side slots. After the sensors enter from the side slots, they slide along the side slots and positioning slots to the bottom of the drill rod and then protrude. In this way, it is not necessary to retract the drill rod during detection, so that the device has multiple detection functions in one unit. During the experiment, it is not necessary to carry multiple detection instruments. Moreover, the device is simple to operate and has high detection efficiency.

[0030] 2. After multiple sets of sensors are placed, the data cable is plugged into the data connector on the outside of the lifting platform. This makes it easy to connect multiple sets of sensors for detection at one time. During detection, it can monitor in real time, continuously measure and record data. At the same time, the data collected by the sensors will be uploaded to the data receiver, and then centrally processed and analyzed by the processor.

[0031] 3. In this invention, when the drill rod is drilling, in order to prevent soil from entering the side groove, a fixed column can be used to block it. After the drilling is completed, the angle of the fixed column is adjusted so that the side groove and the positioning groove are aligned and overlapped, so that the sensor can be placed, thereby achieving the purpose of easy adjustment.

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] Please see Figures 1-6 This invention provides a technical solution: a multifunctional experimental device for comprehensive determination of hydrogeological parameters includes a base 1, with columns 2 fixedly installed at the four corners of the top of the base 1, and a lifting platform 3 movably installed at the top of the columns 2. An equipment box 4 is fixedly installed at the center of the top of the lifting platform 3. A mounting base 5 is fixedly installed at the center of the bottom of the lifting platform 3. A drill rod 7 is provided at the bottom of the mounting base 5, and a fixed column 8 is movably installed at the center of the drill rod 7. Side grooves 9 are formed at the four corners of the drill rod 7, and positioning grooves 10 are formed at the four corners of the outer wall of the fixed column 8. Sensors 11 are movably installed inside the positioning grooves 10 and the side grooves 9. A motor 12 is fixedly installed at the center of the bottom of the inner side of the equipment box 4, and two connecting plates 6 are fixedly installed at the output shaft end of the motor 12. The bottom end of 6 is fixedly connected to the top end of drill rod 7. Data receiver 13 and processor 14 are respectively set at both ends of the equipment box 4 near motor 12. Backup power supply 32 is set at the top of the inside of equipment box 4. Backup power supply 32 is electrically connected to motor 12. When using this device, the device is fixed on the ground, and then the drill rod 7 is used to drill a hole in the ground. After drilling the hole, sensors 11 with different detection functions are inserted into the top of the four side slots 9 in sequence. After the sensors 11 enter from the side slots 9, they slide along the side slots 9 and the positioning slots 10 to the bottom end of drill rod 7 and then protrude. In this way, it is not necessary to retract drill rod 7 during detection, so that this device has multiple detection functions in one unit. During the experiment, it is not necessary to carry multiple detection instruments. Moreover, the device is simple to operate and has high detection efficiency.

[0041] like Figure 3 As shown, several data connectors 15 are provided on the outside of one side of the lifting platform 3. A lead wire 16 is fixedly connected to the top of the sensor 11, and a data line 17 is connected to the top of the lead wire 16. The data line 17 is plugged into the data connector 15. After multiple sets of sensors 11 are placed, the end of the data line 17 is plugged into the data connector 15 on the outside of one side of the lifting platform 3. This makes it easy to connect multiple sets of sensors 11 for detection at one time. During detection, it can monitor in real time, continuously measure and record data. At the same time, the data collected by the sensors 11 will be uploaded to the data receiver 13, and then processed and analyzed centrally by the processor 14.

[0042] like Figure 5As shown, a connecting rod 18 is movably mounted on the top of the drill rod 7 via a bearing. A toggle block 19 is fixedly connected to the top of the connecting rod 18. A fixing column 8 is fixedly connected to the bottom of the connecting rod 18. A shaft seat 20 is fixedly mounted on the bottom of the drill rod 7. The shaft seat 20 and the fixing column 8 are movably connected via a rotating shaft. When the drill rod 7 is drilling, the fixing column 8 can block the soil from entering the side groove 9. After drilling is completed, the angle of the fixing column 8 is adjusted so that the side groove 9 and the positioning groove 10 are aligned and overlapped. This allows the sensor 11 to be placed, thus facilitating adjustment.

[0043] like Figure 5 As shown, a second spring 21 is fixedly connected to the bottom end of the output shaft of the motor 12, a cross head 22 is fixedly connected to the top end of the toggle block 19, and a cross sleeve 23 is fixedly connected to the bottom end of the second spring 21. The cross sleeve 23 is engaged with the cross head 22. After the sensor 11 is placed, the cross sleeve 23 is released, and the second spring 21 will press down on the cross sleeve 23 to position the cross sleeve 23 onto the cross head 22. This will prevent the toggle block 19 from rotating, thereby achieving the purpose of facilitating the limiting position.

[0044] like Figure 4 As shown, the base 1 is equipped with a first spring 24 at the bottom of each of the four columns 2. The top of each of the four first springs 24 is fixedly connected to a pad. The outside of each of the four first springs 24 is covered with a dust cover 25. The four dust covers 25 are made of rubber. The top of each column 2 is fixedly connected to an anti-detachment ring 33. A linear bearing 34 is provided between the column 2 and the lifting platform 3. When the lifting platform 3 is raised or lowered, it slides along the axis of the column 2 through the linear bearing 34, making the sliding smoother. When the lifting platform 3 is lowered, the first springs 24 can provide synchronous support at the bottom, making the descent speed stable. When the drill rod 7 is retracted, the first springs 24 can also support the lifting platform 3. The dust cover 25 on the outside of the first springs 24 can prevent dust and also prevent the first springs 24 from pinching the body when compressed.

[0045] like Figure 1 As shown, brackets 26 are fixedly installed on both sides of the top center of the lifting platform 3. A crossbar 27 is fixedly installed on the top of the two brackets 26. A handle 28 is fixedly installed on both ends of the crossbar 27. Using the handle 28 can achieve the purpose of portability.

[0046] like Figure 1 As shown, shaft brackets 29 are fixedly installed on the top of each of the four corners of the base 1. Insert rods 30 are connected to the internal threads of the shaft brackets 29. A crank handle 31 is fixedly installed on the top of the insert rods 30. The equipment is carried to the test site, and then the equipment is placed on the ground. Then the crank handle 31 is turned. When the crank handle 31 is turned, it drives the insert rods 30 to rotate synchronously and then penetrate into the ground and fix them. This makes the equipment more stable when drilling.

[0047] Experimental method of a multifunctional experimental apparatus for comprehensive determination of hydrogeological parameters:

[0048] Step 1: First, carry the equipment to the test site, then place the equipment on the ground, then turn the crank handle 31. When the crank handle 31 turns, it drives the insertion rod 30 to rotate synchronously and then penetrates into the ground and fixes itself. Then connect the motor 12 to the external power supply. If used in the field, the backup power supply 32 of the equipment can be used to supply power.

[0049] Step 2: After the motor 12 is connected to the power supply, start the motor 12. After the motor 12 starts, it controls the drill rod 7 to rotate and penetrate deeper into the ground. When the drill rod 7 drills to the specified depth, pull up the cross sleeve 23 and lift the cross sleeve 23 from the cross head 22. Then rotate the actuating block 19. After the cross sleeve 23 is released, the second spring 21 will press down on the cross sleeve 23 and position the cross sleeve 23 on the cross head 22. This will prevent the actuating block 19 from rotating back.

[0050] Step 3: Rotate the toggle block 19. The toggle block 19 drives the fixed column 8 inside the drill rod 7 to rotate by the connecting rod 18 until the side groove 9 overlaps with the positioning groove 10. Then, the sensors 11 with different detection functions are put into the top of the four side grooves 9 in sequence.

[0051] Step 4: After the sensor 11 enters from the side groove 9, it slides along the side groove 9 and the positioning groove 10 to the bottom of the drill rod 7 and then protrudes. In this way, it is not necessary to retract the drill rod 7 during the test. After multiple sets of sensors 11 are placed, the end of the data cable 17 is plugged into the data connector 15 on the outside of the side of the lifting platform 3. In this way, the data collected by the sensor 11 is uploaded to the data receiver 13, and then processed and analyzed centrally by the processor 14.

[0052] Step 5: After the experiment is completed, unplug the data cable 17, then retract the sensor 11, then use the motor 12 to remove the drill rod 7 from the ground, then remove the insertion rod 30 from the ground, and finally carry the equipment by holding the handles 28 at both ends of the crossbar 27.

[0053] Working principle: First, carry the equipment to the testing site, then place the equipment on the ground. Next, turn the crank handle 31. When the crank handle 31 rotates, it drives the insertion rod 30 to rotate synchronously and then penetrates into the ground and fixes itself. Then, connect the motor 12 to an external power source. If used in the field, the equipment's built-in backup power supply 32 can be used to supply power. After the motor 12 is connected to the power source, start the motor 12. After the motor 12 starts, it controls the drill rod 7 to rotate and penetrate into the ground. When the drill rod 7 drills to the specified depth, pull up the cross sleeve 23 to lift it from the cross head 22. Then, turn the actuating block 19. After releasing the cross sleeve 23, the second spring 21 will press down on the cross sleeve 23, positioning the cross sleeve 23 onto the cross head 22. This prevents the actuating block 19 from rotating back. Turning the actuating block 19 drives the drill through the connecting rod 18. The fixed column 8 inside the rod 7 is rotated until the side groove 9 overlaps with the positioning groove 10. Then, sensors 11 with different detection functions are inserted sequentially from the top of the four side grooves 9. After the sensor 11 enters from the side groove 9, it slides along the side groove 9 and the positioning groove 10 to the bottom of the drill rod 7 and is exposed. In this way, the drill rod 7 does not need to be retracted during the test. After multiple sets of sensors 11 are placed, the end of the data cable 17 is plugged into the data connector 15 on the outside of the side of the lifting platform 3. In this way, the data collected by the sensor 11 is uploaded to the data receiver 13 and then centrally processed and analyzed by the processor 14. When the experiment is completed, the data cable 17 is unplugged, and then the sensor 11 is retracted. Then, the drill rod 7 is taken out of the ground by the motor 12, and then the insertion rod 30 is taken out of the ground. Finally, the equipment is carried by holding the handles 28 at both ends of the crossbar 27.
