Description

Technical Field

[0001] This application relates to the technical field of geological exploration, and in particular to a portable, multifunctional hydrogeological exploration device. Background Technology

[0002] Hydrogeological exploration refers to the investigation of groundwater distribution and its relationship with the geological environment, and is mainly used in water resource development, engineering construction, mining and other fields.

[0003] Existing hydrogeological exploration equipment typically uses borehole testing. When in use, the drilling rig drills holes in the rock strata, and then samples the rock cores from the boreholes to obtain the geological conditions within the sampling holes, and samples the groundwater within the boreholes to obtain the hydrological conditions within the boreholes.

[0004] Currently, existing hydrogeological exploration equipment requires drilling before use, making the exploration process complex and the equipment inconvenient to carry. Summary of the Invention

[0005] To make hydrogeological exploration equipment easy to carry, this application provides a portable and multifunctional hydrogeological exploration device.

[0006] This application provides a portable, multifunctional hydrogeological exploration device, which adopts the following technical solution: A portable, multifunctional hydrogeological exploration device includes a platform body, a transient electromagnetic instrument, a support assembly, a limiting assembly, and a drive assembly. The platform body is horizontally positioned, and the transient electromagnetic instrument is rotatably mounted at the bottom of the platform body. The support assembly is located on the platform body and serves to support the platform body. The limiting assembly is located on the platform body and serves to limit the position of the support assembly. The drive assembly is located on the platform body and includes a lead screw, a first drive unit, and a second drive unit. The lead screw is vertically inserted into the platform body. The first drive unit is located on the platform body and serves to drive the limiting assembly to stop limiting the position of the support assembly. The second drive unit is located on the platform body and serves to drive the transient electromagnetic instrument to rotate.

[0007] By adopting the above technical solution, the hydrogeological exploration device is used when the operator rotates the lead screw, which drives the first drive unit to work. The first drive unit releases the locking component of the limit assembly from the support assembly, allowing the support assembly to work and support the platform body. At this time, the second drive unit drives the transient electromagnetic instrument to rotate to a vertical position. The operator controls the transient electromagnetic instrument to work, and the transient electromagnetic instrument emits a pulsed magnetic field into the ground. During the interval of the pulsed magnetic field, the transient electromagnetic instrument uses coils to observe the secondary induced eddy current field in the underground medium, thereby realizing the hydrogeological exploration work. After the transient electromagnetic instrument in the vertical position completes the exploration work, the operator continues to rotate the lead screw, which drives the second drive unit to work. The second drive unit drives the transient electromagnetic instrument to rotate, adjusting the detection angle of the transient electromagnetic instrument and expanding its exploration range. After the exploration is completed, the operator drives the limit assembly to release the locking component of the support assembly, making the support assembly easy to reset. When the support assembly is reset, the limit assembly automatically resets and locks the support assembly, making the device easy to reuse. By integrating the support assembly and drive assembly into the platform body, the device is easy for the operator to carry.

[0008] Optionally, the support assembly includes a first support portion, a second support portion, and a connecting frame; the first support portion is located on one side of the platform body, and the second support portion is located on the side of the platform body away from the first support portion; the first support portion includes a first slide rod and a first support rod; a first clearance groove is formed at the bottom end of the platform body, the first slide rod is vertically disposed in the first clearance groove, the first support rod is sleeved on the first slide rod and fixedly connected to the platform body, the first support rod is slidably connected to the first slide rod, and the limiting assembly is used to limit the first slide rod; the second support portion includes a second slide rod and a second support rod; a second clearance groove is formed at the bottom end of the platform body, the second slide rod is vertically disposed in the second clearance groove, the second support rod is sleeved on the second slide rod and fixedly connected to the platform body, the second support rod is slidably connected to the second slide rod; the connecting frame is horizontally disposed and fixedly connected to the bottom ends of the first slide rod and the second slide rod respectively.

[0009] By adopting the above technical solution, during use, the first drive unit drives the limiting component to release the limiting of the first slide rod, the operator lifts the platform body, the first slide rod slides out of the first support rod in the vertical direction, and the second slide rod slides out of the second support rod in the vertical direction. The horizontally set connecting frame makes the first slide rod and the second slide rod slide synchronously. When the first slide rod slides to the designated position, the limiting component limits the first slide rod. The first slide rod and the second slide rod form a double-sided symmetrical support for the platform body, making the platform body less prone to shaking during exploration.

[0010] Optionally, the limiting component includes a limiting block and a first spring; a limiting groove is formed on the first slide rod, and a receiving hole is formed on the first support rod; the limiting block is horizontally arranged, with one end of the limiting block located in the limiting groove and the other end located in the receiving hole, and the limiting block is slidably connected to the first slide rod; the first spring is horizontally arranged in the limiting groove, and both ends are fixedly connected to the first slide rod and the limiting block respectively, and the first driving part is used to drive the limiting block to slide into the limiting groove.

[0011] By adopting the above technical solution, during use, the first driving unit drives the limiting block to slide horizontally, one end of the limiting block disengages from the receiving hole, and the limiting block slides completely into the limiting groove. The first spring is in a compressed state. At this time, the operator lifts the platform body, and the first slide rod slides out of the first support rod vertically. When the limiting groove is aligned with the limiting hole, the first spring returns to its original position, and one end of the limiting block is located in the limiting hole, thereby limiting the first slide rod and locking the distance between the first slide rod and the first support rod, making it easier for the first slide rod and the second slide rod to support the platform body.

[0012] Optionally, the first driving unit includes a driving block, a locking block, and a second spring; the platform body has a driving groove, the driving block is horizontally disposed in the driving groove and threadedly connected to the lead screw, and the driving block has a locking groove; the locking block is horizontally disposed, with one end located in the locking groove, the locking block is slidably connected to the driving block, and the end of the locking block away from the lead screw has a guide slope; the second spring is horizontally disposed in the locking groove, and both ends are fixedly connected to the locking block and the driving block respectively, and the elastic coefficient of the second spring is greater than the elastic coefficient of the first spring.

[0013] By adopting the above technical solution, when the lead screw rotates, the drive block is threadedly connected to the lead screw, and the drive groove limits the drive block, allowing the drive block to slide along the length of the lead screw. When the locking block abuts against the first support rod, the guide slope on the locking block drives the locking block to slide into the locking groove, and the second spring is in a compressed state. When the locking groove is aligned with the receiving hole, the elastic coefficient of the second spring is greater than that of the first spring, and the second spring resets. The second spring drives one end of the locking block to be located in the receiving hole, and the locking block presses against the limiting block. The limiting block slides completely into the limiting groove, and the first spring is in a compressed state. When the operator hears the sound of the locking block colliding with the limiting block, the operator stops rotating the lead screw and raises the platform body, making it easier for the transient electromagnetic instrument to explore underground hydrogeological conditions.

[0014] Optionally, the second drive unit includes a first bevel gear, a drive rod, a second bevel gear, a first synchronous pulley, a second synchronous pulley, and a synchronous belt; the first bevel gear is horizontally arranged and fixedly connected to the bottom end of the lead screw; the drive rod is horizontally arranged and rotatably connected to the platform body; the second bevel gear is vertically arranged and fixedly connected to the drive rod, and the second bevel gear meshes with the first bevel gear; the first synchronous pulley is vertically arranged and fixedly connected to the drive rod; the second synchronous pulley is vertically arranged and fixedly connected to the rotating shaft of the transient electromagnetic instrument; the synchronous belt is located at the bottom end of the platform body, and its two ends mesh with the first synchronous pulley and the second synchronous pulley, respectively.

[0015] By adopting the above technical solution, when the operator rotates the lead screw, the lead screw drives the first bevel gear to rotate, the first bevel gear drives the second bevel gear to rotate, the second bevel gear drives the drive rod to rotate, the drive rod drives the first synchronous pulley to rotate, the first synchronous pulley drives the synchronous belt to rotate, the synchronous belt drives the second synchronous pulley to rotate, and the second synchronous pulley drives the transient electromagnetic instrument to rotate. When the slot and the receiving slot are aligned, the transient electromagnetic instrument rotates to a vertical position. After the transient electromagnetic instrument in the vertical position completes the exploration work, the operator continues to rotate the lead screw, which drives the second synchronous pulley to rotate, and the second synchronous pulley drives the transient electromagnetic instrument to rotate. When the transient electromagnetic instrument rotates along the transient electromagnetic... After the magnetometer's rotating shaft rotates 45 degrees clockwise, the bottom end of the drive block abuts against the bottom wall of the drive groove, preventing the lead screw from rotating further. The operator stops rotating the lead screw and controls the transient electromagnetic instrument to work. After the transient electromagnetic instrument completes its exploration work by rotating 45 degrees clockwise, the operator rotates the lead screw in the opposite direction, causing the drive block to slide vertically. When the transient electromagnetic instrument rotates 90 degrees counterclockwise along its rotating shaft, the top end of the drive block abuts against the top wall of the drive groove, preventing the lead screw from rotating further. The operator stops rotating the lead screw and controls the transient electromagnetic instrument to work, thus expanding its exploration range.

[0016] Optionally, a handwheel is fixedly connected to the top of the lead screw, and the handwheel is horizontally positioned.

[0017] By adopting the above technical solution, when in use, the operator can turn the handwheel to drive the lead screw to rotate, making it easier for the operator to drive the lead screw to rotate.

The solar panel is electrically connected to the transient electromagnetic instrument. An adjustment component is provided on the platform body to adjust the rotation angle of the rotating plate.

[0019] By adopting the above technical solution, when in use, the rotation angle of the rotating plate can be adjusted by adjusting the component, so that the solar panel can easily adapt to the angle of sunlight.

[0020] Optionally, the adjustment assembly includes an adjusting telescopic rod and an airbag; the fixed end of the adjusting telescopic rod is rotatably disposed at the top of the platform body, and the movable end of the adjusting telescopic rod is rotatably disposed at the bottom of the rotating plate; the rod cavity of the adjusting telescopic rod is filled with liquid; the airbag is vertically disposed in the first clearance groove and fixedly connected to the platform body; the airbag is hollow inside and filled with liquid; the airbag is in a compressed state; and the airbag is connected to the rod cavity of the adjusting telescopic rod through a pipe.

[0021] By adopting the above technical solution, when the operator lifts the platform body, the airbag resets, the liquid in the rod cavity of the telescopic rod flows into the airbag through the pipe, the volume of the rod cavity of the telescopic rod decreases, and the movable end of the telescopic rod extends, so that the rotating plate rotates to a position that is compatible with sunlight.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. By setting up support components, the platform body is less prone to shaking during the exploration process; 2. By setting up a second drive unit, the exploration range of the transient electromagnetic instrument is expanded; 3.

[0027] When using the hydrogeological exploration device, the operator drives the limiting component 4 to release the limiting component 3, which then supports the platform body. The transient electromagnetic instrument 2 then conducts hydrogeological exploration. After the transient electromagnetic instrument 2 completes its exploration work, the drive component 5 drives the transient electromagnetic instrument 2 to rotate, adjusting its detection angle and expanding its exploration range.

A handle 15, horizontally mounted, is fixedly connected to one side of the platform body 1. The transient electromagnetic instrument 2 is vertically mounted at the bottom of the platform body 1 and is rotatably connected to the platform body 1. The solar panel 141 is electrically connected to the battery of the transient electromagnetic instrument 2 and is used to power the battery of the transient electromagnetic instrument 2.

[0029] Reference Figure 1 and Figure 2 The support assembly 3 includes a first support portion 31, a second support portion 32, and a connecting frame 33. The first support portion 31 is located on one side of the platform body 1, and the second support portion 32 is located on the side of the platform body 1 away from the first support portion 31. The first support portion 31 includes a first slide rod 311 and a first support rod 312. The first slide rod 311 is vertically arranged in the first clearance groove 11 and is rectangular in shape.

[0030] Reference Figure 2 and Figure 3 The first slide rod 311 has a limiting groove 3111, which is rectangular in shape. A first support rod 312 is vertically mounted on the first slide rod 311 and fixedly connected to the platform body 1. The first support rod 312 is rectangular and hollow inside, and it slides vertically with the first slide rod 311. A receiving hole 3121 is provided on the first support rod 312, which is rectangular in shape and directly opposite the limiting groove 3111. A limiting hole 3122 is also provided on the first support rod 312, which is rectangular in shape.

[0031] Reference Figure 2Three second support parts 32 are provided, each corresponding to one of the three second clearance grooves 12. Each second support part 32 includes a second sliding rod 321 and a second support rod 322. The second sliding rod 321 is vertically arranged within the second clearance groove 12 and is rectangular in shape. The second support rod 322 is vertically sleeved on the second sliding rod 321 and fixedly connected to the platform body 1. The second support rod 322 is rectangular in shape and hollow inside. The second support rod 322 and the second sliding rod 321 are slidably connected in the vertical direction. The connecting frame 33 is horizontally arranged and fixedly connected to the bottom end of the first sliding rod 311 and the bottom end of the second sliding rod 321, respectively.

[0032] Reference Figure 3 The limiting component 4 includes a limiting block 41 and a first spring 42. The limiting block 41 is horizontally positioned and rectangular in shape. One end of the limiting block 41 is located within the limiting groove 3111, and the other end is located within the receiving hole 3121. The limiting block 41 and the first slide rod 311 are slidably connected along the length of the platform body 1. The first spring 42 is horizontally positioned within the limiting groove 3111, and both ends are fixedly connected to the first slide rod 311 and the limiting block 41, respectively.

[0033] In use, the drive assembly 5 drives the limiting block 41 to slide horizontally. One end of the limiting block 41 disengages from the receiving hole 3121, and the limiting block 41 slides completely into the limiting groove 3111. The first spring 42 is in a compressed state. At this time, the operator lifts the platform body 1, and the first slide rod 311 slides out of the first support rod 312 in the vertical direction. The second slide rod 321 slides out of the second support rod 322 in the vertical direction. The horizontally set connecting frame 33 makes the first slide rod 311 and the second slide rod 321 slide synchronously. When the limiting groove 3111 is aligned with the limiting hole 3122, the first spring 42 returns to its original position, and one end of the limiting block 41 is located in the limiting hole 3122, thereby limiting the first slide rod 311 and locking the distance between the first slide rod 311 and the first support rod 312, making it easy for the first slide rod 311 and the second slide rod 321 to support the platform body 1.

[0034] Reference Figure 1 and Figure 3 The drive assembly 5 includes a lead screw 51, a first drive unit 52, and a second drive unit 53. The lead screw 51 passes sequentially through the platform body 1 and the drive groove 13, with both ends located on the outer sides of the platform body 1. The first drive unit 52 is located on the platform body 1 and is used to drive the limiting block 41 to slide from the receiving hole 3121 into the limiting slide groove 3111. The second drive unit 53 is located on the platform body 1 and is used to drive the transient electromagnetic instrument 2 to rotate.

[0035] A handwheel 511 is horizontally mounted at the top of the lead screw 51, and the handwheel 511 is fixedly connected to the lead screw 51. The first drive unit 52 includes a drive block 521, a locking block 522, and a second spring 523. The drive block 521 is horizontally mounted in the drive groove 13 and threadedly connected to the lead screw 51. The drive block 521 is slidably connected to the platform body 1 in the vertical direction. A locking groove 5211 is provided on the drive block 521, and the locking groove 5211 is rectangular. When the locking groove 5211 is aligned with the receiving hole 3121, the upper and lower gaps of the drive block 521 are equal, that is, the drive block 521 is located in the middle of the drive groove 13.

[0036] The locking block 522 is horizontally positioned, with one end located within the locking slot 5211. The locking block 522 and the drive block 521 are slidably connected along the length of the platform body 1. The end of the locking block 522 away from the lead screw 51 is provided with a guide slope, which is inclined downwards from the side away from the lead screw 51 to the side closer to the lead screw 51. The second spring 523 is horizontally positioned within the locking slot 5211, with both ends fixedly connected to the locking block 522 and the drive block 521, respectively. The spring force coefficient of the second spring 523 is greater than that of the first spring 42.

[0037] Reference Figure 1 and Figure 4 The second drive unit 53 includes a first bevel gear 531, a drive rod 532, a second bevel gear 533, a first synchronous pulley 534, a second synchronous pulley 535, and a synchronous belt 536. The first bevel gear 531 is horizontally positioned at the bottom end of the platform body 1 and is fixedly connected to the bottom end of the lead screw 51. The drive rod 532 is horizontally positioned and is circular in shape, rotatably connected to the platform body 1 via a bracket. The second bevel gear 533 is vertically positioned and fixedly connected to the drive rod 532, meshing with the first bevel gear 531. The first synchronous pulley 534 is vertically positioned and fixedly connected to the drive rod 532. The second synchronous pulley 535 is vertically positioned and fixedly connected to the rotating shaft of the transient electromagnetic instrument 2. The synchronous belt 536 is located at the bottom end of the platform body 1, with both ends meshing with the first synchronous pulley 534 and the second synchronous pulley 535, respectively.

[0038] In the hydrogeological exploration device, the operator rotates the lead screw 51 via the handwheel 511. The lead screw 51 drives the first bevel gear 531 to rotate, which in turn drives the second bevel gear 533 to rotate. The second bevel gear 533 drives the drive rod 532 to rotate, which in turn drives the first synchronous pulley 534 to rotate. The first synchronous pulley 534 drives the synchronous belt 536 to rotate, which in turn drives the second synchronous pulley 535 to rotate. The second synchronous pulley 535 drives the transient electromagnetic instrument 2 to rotate. At the same time, the lead screw 51 drives the drive block 521 to slide along the length of the lead screw. When the locking block 522 abuts against the first support rod 312, the guide slope on the locking block 522 drives the locking block 522 to slide into the locking groove 5211, and the second spring 523 is in a compressed state.

[0039] When the slot 5211 is aligned with the receiving hole 3121, the transient electromagnetic instrument 2 rotates to a vertical position. The spring force coefficient of the second spring 523 is greater than that of the first spring 42, so the second spring 523 resets. The second spring 523 drives one end of the locking block 522 to be located in the receiving hole 3121. The locking block 522 presses against the limiting block 41, and the limiting block 41 slides completely into the limiting groove 3111. The first spring 42 is in a compressed state. When the operator hears the sound of the locking block 522 colliding with the limiting block 41, the operator stops rotating the lead screw 51 and raises the platform body 1. When the limiting groove 3111 is aligned with the limiting hole 3122, the platform body 1 completes the lifting operation, and the operator controls the transient electromagnetic instrument 2 to work.

[0040] After the transient electromagnetic instrument 2 in its vertical position completes its exploration work, the operator continues to rotate the lead screw 51. The lead screw 51 drives the second synchronous wheel 535 to rotate, which in turn drives the transient electromagnetic instrument 2 to rotate. When the transient electromagnetic instrument 2 rotates 45 degrees clockwise along its rotation axis, the bottom end of the drive block 521 abuts against the bottom wall of the drive groove 13, preventing the lead screw 51 from rotating further. The operator then stops rotating the lead screw 51 and controls the transient electromagnetic instrument 2 to continue operating. After the transient electromagnetic instrument 2 completes its exploration work after rotating 45 degrees clockwise, the operator rotates the lead screw 51 in the opposite direction. The lead screw 51 drives the drive block 521 to slide upwards. When the transient electromagnetic instrument 2 rotates 90 degrees counterclockwise along its rotation axis, the top end of the drive block 521 abuts against the top wall of the drive groove 13, preventing the lead screw 51 from rotating further. The operator then stops rotating the lead screw 51 and controls the transient electromagnetic instrument 2 to continue operating.

[0041] Reference Figure 1 and Figure 2The adjustment assembly 6 includes an adjusting telescopic rod 61 and an airbag 62. The fixed end of the adjusting telescopic rod 61 is hinged to the top of the platform body 1, and the movable end of the adjusting telescopic rod 61 is hinged to the bottom of the rotating plate 14. The rod cavity of the adjusting telescopic rod 61 is filled with liquid. The airbag 62 is vertically arranged in the first clearance groove 11 and is fixedly connected to the platform body 1. The airbag 62 is hollow inside and filled with liquid. The airbag 62 is in a compressed state, and the airbag 62 is connected to the rod cavity of the adjusting telescopic rod 61 through a pipe.

[0042] When the operator lifts the platform body 1, the locking block 522 slides completely into the limiting groove 3111, the airbag 62 resets, the liquid in the rod cavity of the adjusting telescopic rod 61 flows into the airbag 62 through the pipe, the volume of the rod cavity of the adjusting telescopic rod 61 decreases, the movable end of the adjusting telescopic rod 61 extends, so that the rotating plate 14 rotates to a position that is compatible with sunlight.

[0043] The implementation principle of a portable, multifunctional hydrogeological exploration device according to an embodiment of this application is as follows: During hydrogeological exploration, the operator places the device in the exploration area. The operator rotates the lead screw 51 by handwheel 511. The lead screw 51 drives the second synchronous wheel 535 to rotate. The second synchronous wheel 535 drives the transient electromagnetic instrument 2 to rotate. At the same time, the lead screw 51 drives the drive block 521 to slide along the length of the lead screw. When the slot 5211 is aligned with the receiving hole 3121, the transient electromagnetic instrument 2 rotates to a vertical position. The compressed second spring 523 drives the locking block 522 to press the limiting block 41. The limiting block 41 slides completely into the limiting groove 3111.

[0044] When the operator hears the sound of the locking block 522 colliding with the limiting block 41, the operator stops rotating the lead screw 51 and raises the platform body 1. The compressed airbag 62 drives the movable end of the adjusting telescopic rod 61 to extend, causing the rotating plate 14 to rotate to a position suitable for sunlight. During the process of the operator raising the platform body 1, the first slide rod 311 slides out of the first support rod 312 in the vertical direction, and the second slide rod 321 slides out of the second support rod 322 in the vertical direction. When the limiting slide groove 3111 is aligned with the limiting hole 3122, the first spring 42 drives one end of the limiting block 41 to be located in the limiting hole 3122, and the platform body 1 completes the raising operation.

[0045] The operator controls the transient electromagnetic instrument 2 to work. The transient electromagnetic instrument 2 emits a pulsed magnetic field into the ground. During the interval between pulsed magnetic field intervals, the transient electromagnetic instrument 2 uses coils to observe the secondary induced eddy current field in the underground medium, thereby realizing the exploration of hydrogeology.

[0046] After the transient electromagnetic instrument 2 in its vertical position completes the exploration work, the operator continues to rotate the lead screw 51, which drives the transient electromagnetic instrument 2 to rotate. When the transient electromagnetic instrument 2 rotates 45 degrees clockwise along its rotation axis, the bottom end of the drive block 521 abuts against the bottom wall of the drive groove 13. The operator then stops rotating the lead screw 51 and controls the transient electromagnetic instrument 2 to work.

[0047] After the transient electromagnetic instrument 2 completes its exploration work by rotating 45 degrees clockwise, the operator rotates the lead screw 51 in the opposite direction. The lead screw 51 drives the drive block 521 to slide upward. When the transient electromagnetic instrument 2 rotates 90 degrees counterclockwise along its rotation axis, the top of the drive block 521 abuts against the top wall of the drive groove 13. At this point, the operator stops rotating the lead screw 51 and controls the transient electromagnetic instrument 2 to work.

[0048] After the exploration is completed, the operator drives the limiting block 41 to slide completely into the limiting groove 3111. The operator presses down on the platform body 1, and the first slide rod 311 slides into the first support rod 312, and the second slide rod 321 slides into the second support rod 322. When the limiting block 41 is aligned with the receiving hole 3121, the first spring 42 resets and drives one end of the limiting block 41 to be located in the receiving hole 3121, making the device easy to reuse.

[0049] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
