Technical Field

[0001] This invention relates to the field of geological exploration technology, specifically to a groundwater depth sampling device for geological exploration. Background Technology

[0002] Geological exploration is the process of detecting and studying the geological structure, mineral resources, and groundwater of the Earth's surface and depths through a series of scientific methods and technologies. Its core purpose is to obtain geological information to provide a scientific basis for mineral development, engineering construction, and environmental protection. Groundwater sampling is a fundamental and important task in environmental monitoring, water resource management, and geological research. It involves obtaining representative water samples from underground aquifers to analyze their physical, chemical, and biological characteristics, thereby assessing groundwater quality, pollution status, and dynamic changes. However, most existing groundwater sampling is conducted outdoors, and existing sampling devices are inconvenient to carry outdoors, and it is also inconvenient to sample groundwater at fixed depths or to sample groundwater at different depths at once, resulting in poor sampling efficiency. In addition, the sampling devices are not easy to stably fix on the ground during use, resulting in poor stability.

[0012] This invention provides a groundwater depth sampling device for geological exploration, which has the following beneficial effects: 1. This groundwater depth sampling device for geological exploration uses self-locking casters to move the housing. The sampling mechanism can be stored inside the housing, facilitating the movement and carrying of the device. When sampling, the top cover is moved upwards using an electric telescopic rod, and the top cover moves the sampling mechanism out of the housing. The sampling seat is lowered into the groundwater by releasing the rope on the winding drum. The depth of the sampling seat is controlled by the depth scale on the rope. In addition, the sampling seat is equipped with multiple sampling tubes, which can be lowered into the well at the same time to sample groundwater at different depths, resulting in high work efficiency.

[0013] 2. In this geological exploration groundwater depth sampling device, when the top cover moves, it drives two racks to move upward synchronously. The meshing transmission between the two racks and two spur gears drives two drive shafts and four first bevel gears to rotate. The meshing transmission between the four first bevel gears and four second bevel gears drives the screw to rotate. The threaded engagement between the screw and the drive screw block drives the drive screw block and the pin to move downward, so that the bottom end of the pin is inserted into the ground to fix the box body, ensuring the stability of the sampling device during sampling.

[0014] 3. In this geological exploration groundwater depth sampling device, when one rack moves upward, it drives the push-pull frame and the first piston plate to move upward synchronously. The first piston plate pushes the air in the inner cavity of the push-pull box to be introduced into the inner cavity of the two support boxes through the two vent pipes. The air entering the inner cavity of the support box pushes the second piston plate and the extension frame to move laterally. The extension frame drives the guide roller to move above the sampling hole so that the guide groove on the guide roller can support and guide the cable during sampling, ensuring that the sampling seat can be smoothly moved down into the groundwater for sampling.

[0021] The sampling mechanism 8 includes two hangers 37 fixedly connected to the bottom surface of the top cover 4. A winding drum 38 is rotatably connected between the two hangers 37 via bearings. A rope 39 is wound around the outside of the winding drum 38. A depth scale 56 is provided on the side of the rope 39, with the zero point of the depth scale 56 located on the top surface of the sampling seat 40. A geared brake motor 41 is fixedly installed on the outside of one hanger 37. The output shaft of the geared brake motor 41 is connected to one end of the shaft of the winding drum 38 via a coupling.

The bottom end of the sampling tube 47 abuts against the bottom surface of the inner cavity of the insertion groove 42. The top surface of the sampling base 40 and the side of the top of the insertion groove 42 are provided with marking scales 55. The marking scales 55 are used to identify the sampling depth of the sampling tube 47 in the inner cavity of the corresponding insertion groove 42. The sampling base 40 is provided with a signal receiving controller 54. The signal receiving controller 54 is used to receive the control signal of the remote controller 15, so that the signal receiving controller 54 controls multiple electric push rods 48.

The side of the sampling seat 40 is provided with multiple water inlets 52. The end of the water inlet 52 is connected to the inner cavity of the counterweight groove 51. Through the cooperation of the water inlet 52, water can enter the counterweight groove 51 to increase the weight of the sampling seat 40, which facilitates the downward movement of the sampling seat 40 in the groundwater. In addition, when the sampling seat 40 is lifted upward, the water in the inner cavity of the counterweight groove 51 is discharged through the water inlet 52.

[0022] The storage mechanism 9 includes a storage box 57 fixedly connected to the bottom surface of the top cover 4. The storage box 57 is provided with multiple storage chambers 58. Each of the multiple storage chambers 58 has a support plate 59 fixedly fitted inside. Multiple rubber rings 60 are fitted on the support plate 59. Spare tubes 61 are fitted inside the multiple rubber rings 60. A plug 62 is fitted on the top of the spare tube 61. The bottom end of the spare tube 61 abuts against the bottom surface of the inner cavity of the storage chamber 58 to support the spare tube 61.

[0023] The outer side of the housing 1 is equipped with a control panel 10, which controls the deceleration brake motor 41 and the electric telescopic rod 3 via wires. A transparent protective shell 11 is hinged to the outer side of the housing 1 and outside the control panel 10 via a suspension hinge to protect the control panel 10. A pusher 66 is fixedly installed on the outer side of the housing 1 to push the device. A main power supply 65 is installed at the bottom of the inner cavity of the housing 1, which supplies power to the deceleration brake motor 41, the electric telescopic rod 3 and the control panel 10 via wires. In addition, a charging device for the main power supply 65 is provided on the housing 1. The control method and circuit connection are known technologies and will not be explained in detail.

[0024] The height of the sampling tube 47 is equal to the height of the spare tube 61, and the outer diameter of the sampling tube 47 is equal to the outer diameter of the spare tube 61, ensuring that the sampling tube 47 can be inserted into the rubber ring 60 for storage. At the same time, the spare tube 61 can be installed in the insertion slot 42 for sampling. In addition, the sealing ring 43 can ensure the sealing of the sampling tube 47 and the spare tube 61 installed in the insertion slot 42, so that water can only be sampled from the top of the inner cavity of the insertion slot 42.

[0025] The inner wall of the housing 1 is fixedly connected to a limiting seat 63, and the limiting seat 63 is provided with a limiting hole 64. The inner diameter of the limiting hole 64 is equal to the outer diameter of the sampling seat 40. When the sampling seat 40 is housed in the inner cavity of the housing 1, the sampling seat 40 is inserted into the inner cavity of the limiting hole 64 to limit the sampling seat 40 and prevent the sampling seat 40 from shaking.

[0026] In summary, when using this groundwater depth-fixed sampling device for geological exploration, first, push the housing 1 by holding the push handle 66. Use the self-locking casters 2 to move the device to the side of the borehole after the geological exploration drilling. Use the self-locking function of the casters 2 to initially fix the housing 1. Then, open the transparent protective shell 11 to expose the control panel 10. Use the control panel 10 to start the electric telescopic rod 3. The electric telescopic rod 3 drives the top cover 4 and rack 5 to move upwards synchronously. The top cover 4 drives the sampling mechanism 8 and storage mechanism 9 to move upwards synchronously. Then, during the upward movement of the two racks 5, the meshing transmission between the two racks 5 and the two spur gears 25 drives the two drive shafts 16 and the four first bevel gears 24 to rotate. The meshing transmission between 24 and the four second bevel gears 23 drives the second bevel gears 23 and the screw 20 to rotate. Through the threaded engagement between the screw 20 and the transmission screw block 21, the transmission screw block 21 and the pin 22 move downward, so that the bottom end of the pin 22 is inserted into the ground to fix the housing 1. In addition, when one rack 5 moves upward, it drives the push-pull frame 35 and the first piston plate 34 to move upward. The first piston plate 34 pushes the air in the inner cavity of the push-pull box 33 to be introduced into the inner cavity of the two support boxes 26 through the two vent pipes 32. The air entering the inner cavity of the support box 26 pushes the second piston plate 27 and the extension frame 28 to move laterally. The extension frame 28 drives the guide roller 29 to move above the sampling hole. Then, the water level gauge 13 in the inner cavity of the housing 1 is removed. The depth of the groundwater below the borehole is measured using a water level gauge 13. Meanwhile, the rope 39 is pulled around the guide groove 30 on the guide roller 29, positioning the sampling seat 40 at the bottom of the rope 39 above the borehole. The deceleration brake motor 41 is activated, rotating the winding drum 38 to release the rope 39, allowing the sampling seat 40 to gradually descend into the groundwater. When the bottom of the sampling seat 40 contacts the water surface, groundwater enters the inner cavity of the counterweight trough 51 through the outlet hole 53 and inlet hole 52, increasing the weight of the sampling seat 40 and causing it to sink into the groundwater. Simultaneously, the depth of the sampling seat 40 is controlled using a depth scale 56 on the side of the rope 39. The depth measured by the depth scale 56 is adjusted accordingly. The depth measured by the water level gauge 13 determines the depth to which the sampling seat 40 sinks into the groundwater. When the sampling seat 40 reaches the predetermined depth in the groundwater, the remote control 15 sends a control signal to the signal receiving controller 54 on the sampling seat 40. The signal receiving controller 54 controls the electric push rod 48 to move the rubber sealing block 49 from the top of the sampling tube 47, allowing groundwater to enter the sampling tube 47 for sampling. After sampling, the electric push rod 48 moves the rubber sealing block 49 back to the top of the sampling tube 47 to seal the top of the sampling tube 47. When sampling groundwater at different depths, multiple electric push rods 48 are activated to move multiple rubber sealing blocks 49, allowing multiple sampling tubes 47 to perform sampling.Staff used the marking scale 55 to mark the depth of the water sampled in the sampling tube 47 for subsequent differentiation. Finally, the deceleration brake motor 41 was activated to reverse the winding drum 38, which wound up the rope 39 to remove the sampling seat 40 from the groundwater. As the sampling seat 40 was removed from the water, water in the counterweight trough 51 was discharged from the outlet hole 53. When the sampling seat 40 was pulled out of the hole, multiple electric push rods 48 were activated to move multiple rubber sealing blocks 49 from the top of the sampling tube 47. The sampling tube 47, after sampling groundwater, was pushed upwards from the insertion slot 42 by the push groove 44. The top of the sampling tube 47 was sealed with a plug 62. A spare tube 61 was installed in the insertion slot 42 for subsequent sampling. Simultaneously, the sampling tube 47 containing the sampled water was inserted into the rubber ring 60 on the storage box 57. When the device was moved again, the brake was activated. The electric telescopic rod 3 moves the top cover 4, sampling mechanism 8, and storage mechanism 9 downwards, allowing them to retract back into the inner cavity of the housing 1. Simultaneously, the sampling seat 40 below the sampling mechanism 8 is inserted into the limiting hole 64 to limit its position. Additionally, the top cover 4 moves the rack 5 downwards, and through the transmission between the rack 5, spur gear 25, drive shaft 16, first bevel gear 24, second bevel gear 23, screw 20, and drive screw block 21, the pin 22 is pulled out of the ground, releasing its fixation to the housing 1. Simultaneously, the rack 5 moves the push-pull bracket 35 and the first piston plate 34 downwards. The negative pressure inside the push-pull box 33 causes the vent pipe 32 to draw air into the inner cavity of the support box 26. The negative pressure inside the support box 26 moves the second piston plate 27, guide roller 29, and guide roller 29 back to the side of the housing 1, facilitating movement of the device. The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
