Technical Field

[0001] The invention relates to the technical field of geothermal exploration, in particular to a sample collection and sampling device based on geothermal exploration. Background Art

[0002] Geothermal energy is renewable thermal energy stored in the earth's interior. It is generally concentrated along the edges of tectonic plates and originates from the earth's molten magma and the decay of radioactive substances. Geothermal resources are a very valuable comprehensive mineral resource with multiple functions and wide applications. It is not only a clean energy resource that can be used for power generation and heating, but also a hot brine resource and natural fertilizer water resource for extracting industrial raw materials such as bromine, iodine, borax, potassium salt, and ammonium salt. It is also a valuable medical hot mineral water and drinking mineral water resource as well as a source of domestic water supply. Geothermal resources are hidden deep underground. The exploration of geothermal resources usually requires the use of geothermal exploration sample collection and sampling equipment.

[0008] Furthermore, there are three receiving grooves distributed in an annular shape on the surface of the rotating disk, and six engaging teeth are distributed in an annular shape on the inner side of the receiving groove.

[0009] Furthermore, the engaging teeth are meshed with the rack groove, and the engaging teeth are fixedly connected to the hydraulic cylinder.

[0010] Furthermore, the outer contour of the docking gear is consistent with the inner contour of the wheel groove, and the vertical center line of the docking gear coincides with the vertical center line of the pile body.

[0011] Furthermore, the rotating assembly includes a sliding seat, a sliding groove, a second diesel engine, a rotating wheel and an engaging strip, a sliding groove is provided on the outer side of the bottom of the sliding seat, and the outer side of the top of the sliding seat is connected to the second diesel engine, the output end of the second diesel engine is connected to the rotating wheel, and the outer end of the rotating wheel is connected to the engaging strip.

[0012] Furthermore, the rotating wheel and the meshing bar are meshed with each other, and the meshing bar and the rack groove are meshed with each other.

[0013] Furthermore, the sampling assembly includes a collection tube, a sliding groove and a locking groove. The sliding grooves are provided on both sides of the outside of the collection tube, and the locking groove is provided at the outer end of the sliding groove.

[0014] Furthermore, the entry groove and the locking groove are connected to each other, and the width of the sliding groove and the locking groove is consistent with the diameter of the locking pin.

[0015] The present invention provides a sample collection and sampling device based on geothermal exploration, which has the following beneficial effects: a total of three placement grooves are arranged on the rotating disk, so that the loading point of the pile body can be staggered with the position of the output shaft, so that the equipment can simultaneously realize the pile driving and the loading of the pile body, which can greatly improve the drilling efficiency of the equipment. At the same time, because the loading point of the pile body is staggered with the output shaft, the equipment does not need to stop the operation of the output shaft during the loading process. By adopting a separate assembly connection between the collection tube and the pile body, the collection tube can be collected after the pile body drilling is completed, which can effectively avoid damage caused by direct integration. The connecting hole is located inside the pile body. During the pile body drilling process, the connecting hole has less contact with the outside world, which can effectively avoid the situation that the connecting hole cannot be passed through the collection tube after the drilling is completed. After the collection tube is passed into the inner side of the connecting hole, the soil blocked in the connecting hole can be dredged, so that the collection tube can directly clean the soil in the connecting hole during the connection with the pile body.

[0016] 1. The present invention provides a rack groove on the surface of the pile body, and arranges engaging teeth that can engage with the rack groove in the arranging groove, so that the rotating disk can be quickly connected with the pile body. After the pile body is driven into the soil layer, the rotating disk can be quickly connected with the second pile body through engagement, and the second pile body can be quickly moved to the bottom end of the output shaft by rotation of the rotating disk to perform a second round of pile driving operation. In addition, there are three arranging grooves on the rotating disk, which makes it possible for the loading point of the pile body to be staggered with the position of the output shaft, so that the equipment can realize pile driving and pile loading at the same time, which can greatly improve the drilling efficiency of the equipment. At the same time, because the loading point of the pile body is staggered with the output shaft, the equipment does not need to stop the operation of the output shaft during the loading process, which further improves the drilling efficiency of the equipment.

[0017] 2. In the process of overlapping the pile bodies of the present invention, the pile body at the upper position can extend the docking gear at its bottom into the wheel groove of the pile body at the lower position. The docking gear and the wheel groove are of the same size, which can ensure that the two pile bodies can be stably connected after overlapping. This can reduce the occurrence of drilling azimuth errors due to size deviations in the connection process between the pile bodies. In addition, the inner contour of the directional seat is the same as the outer contour of the pile body, which enables the directional seat to position the downward movement path of the pile body. Through the dual positioning of the directional seat and the docking gear and the wheel groove, the drilling azimuth errors can be greatly avoided, which can effectively improve the positioning and collection accuracy of the equipment.

[0018] 3. In the process of the pile body moving downward, if there is a stone obstacle, the sliding seat can be loosened to make the sliding seat slide on the surface of the slide groove, so that the second diesel engine can drive the rotating wheel to move to a position at the same height as the rack groove on the outer side of the top pile body. At this time, the meshing bar at the outer end of the rotating wheel is fixed to the rack groove, and the second diesel engine is operated to enable the rotating wheel to drive the meshing bar to rotate. During the rotation process, the meshing bar can rotate the pile body through the meshing transmission with the rack groove, and the pile bodies can be combined into one by connecting the docking gear and the wheel groove, so that when the pile body at the top is rotated, It can drive the entire pile body to rotate. The front section of the lowest pile body is connected to a drill bit. The high-speed rotation of the drill bit can drill and break the blocking stones. In addition, during the rotation of the drill bit, the pile body is continuously pressed by the output shaft, so that the pile body can move downward during the rotation, which makes it easier to crush the blocking stones. During the downward movement of the pile body, the second diesel engine can move downward synchronously through the sliding of the sliding seat in the slide groove, which can effectively prevent the meshing bar from disengaging from the rack groove. By rotating the pile body at high speed and cooperating with stamping, it can effectively prevent the pile body from being blocked by stones and being unable to move downward normally.

[0019] 4. The present invention aligns the collection tube with the connecting hole at the top of the pile body and aligns the sliding groove at the outer end thereof with the locking pin, so that the collection tube can be inserted into the inner side of the pile body. Due to the docking between the pile bodies, the connecting holes on the inner sides of the pile bodies can be connected to each other. After the collection tube extends into the connecting hole of the topmost pile body, it can extend out of the connecting hole of the bottommost pile body. The collection tube can be connected to the suction equipment, so that the geothermal source can be collected after contacting with the geothermal source. By adopting the separate assembly connection between the collection tube and the pile body, the collection tube can be collected after the pile body drilling is completed, which can effectively avoid damage caused by direct integration. The connecting hole is located inside the pile body. During the pile body drilling process, the connecting hole has less contact with the outside world, which can effectively avoid the situation that the connecting hole cannot be passed through the collection tube after the drilling is completed. After the collection tube is passed into the inner side of the connecting hole, the soil blocked in the connecting hole can be dredged, so that the collection tube can directly clean the soil in the connecting hole during the connection with the pile body, which further improves the collection stability of the equipment.

[0020] 5. After geothermal collection is completed, the collection tube of the present invention can be rotated to make the locking pin slide from the sliding groove into the locking groove. By connecting the locking pin with the locking groove, a plurality of pile bodies can be connected with the collection tube, so that the plurality of pile bodies can be combined with the collection tube into one. By combining the plurality of pile bodies into one, the difficulty of extracting the pile body from the soil after the geothermal source collection is completed can be greatly reduced, which makes the use of the equipment more convenient.

The clamping teeth 704 are meshed with the rack groove 803, and the clamping teeth 704 and the hydraulic cylinder 705 are connected. The pressure cylinder 705 is fixedly connected, the outer contour of the docking gear 802 is consistent with the inner contour of the wheel groove 804, and the vertical center line of the docking gear 802 coincides with the vertical center line of the pile body 801. The rotating assembly 11 includes a sliding seat 1101, a sliding groove 1102, a second diesel engine 1103, a rotating wheel 1104 and an engaging strip 1105. The sliding groove 1102 is provided on the outer side of the bottom of the sliding seat 1101, and the second diesel engine 1103 is connected to the outer side of the top of the sliding seat 1101. The output end of the second diesel engine 1103 is connected to the rotating wheel 1104, and the outer end of the rotating wheel 1104 is connected to the engaging strip 1105, the rotating wheel 1104 and the engaging strip 1105 are meshed with each other, and the engaging strip 1105 and the rack groove 803 are meshed with each other;

[0031] The specific operation is as follows. After the support seat 1 and the directional seat 10 are placed at the drilling point where drilling is required, the pile body 801 to be driven into the soil is placed in the placement groove 703 on the inner side of the rotating disk 701. At this time, the hydraulic cylinder 705 works to enable the engaging teeth 704 on the inner side of the placement groove 703 to move toward the pile body 801, so that the engaging teeth 704 can engage with the rack groove 803 on the outer end of the pile body 801, which can ensure that the pile body 801 can be stably placed on the inner side of the rotating disk 701. After the pile body 801 is placed inside the rotating disk 701, the first diesel engine 6 works to enable the rotating shaft 702 to drive the rotating disk 701 to rotate, and during the rotation of the rotating disk 701, the pile body 801 can be driven to move to On the same straight line as the output shaft 3, the engaging tooth 704 moves backward to loosen the pile body 801, and the pile body 801 can fall to the inside of the directional seat 10, and the drill bit 9 at the front end is fitted with the ground. Through the operation of the punching machine 2, the output shaft 3 can pass through the punching hole 5 and contact the top of the pile body 801. Through the punching of the punching machine 2, the pile body 801 can gradually enter into the soil layer. By providing a rack groove 803 on the surface of the pile body 801 and arranging the engaging tooth 704 that can engage with the rack groove 803 in the arranging groove 703, the rotating disk 701 can be quickly docked with the pile body 801. After the pile body 801 is driven into the soil layer, the rotating disk 701 can be quickly connected with the second pile body 801 through engagement, and the second pile body 801 can be connected by rotating the rotating disk 701. The pile body 801 quickly moves to the bottom end of the output shaft 3 for the second round of pile body 801 driving operation. In addition, there are three placement grooves 703 on the rotating disk 701, which allows the loading point of the pile body 801 to be staggered with the position of the output shaft 3, so that the equipment can simultaneously realize the driving of the pile body 801 and the loading of the pile body 801, which can greatly improve the drilling efficiency of the equipment. At the same time, because the loading point of the pile body 801 is staggered with the output shaft 3, the equipment does not need to stop the operation of the output shaft 3 during the loading process, which further improves the drilling efficiency of the equipment. In the process of overlapping the pile body 801 and the pile body 801, the pile body 801 in the upper position can extend the docking gear 802 at its bottom into the wheel groove 804 of the pile body 801 in the lower position. , the size of the docking gear 802 is consistent with that of the wheel groove 804, which can ensure that the two pile bodies 801 can be stably connected after overlapping, which can reduce the occurrence of drilling azimuth errors due to size deviations during the connection between the pile bodies 801. In addition, the inner contour of the directional seat 10 is the same as the outer contour size of the pile body 801, which allows the directional seat 10 to also position the downward movement path of the pile body 801. The dual positioning of the directional seat 10, the docking gear 802, and the wheel groove 804 can greatly avoid drilling azimuth errors, which can effectively improve the positioning and collection accuracy of the equipment. During the downward movement of the pile body 801, if it encounters a stone obstacle, the sliding seat 1101 can be loosened to allow the sliding seat 1101 to slide on the surface of the slide groove 1102.This enables the second diesel engine 1103 to drive the rotating wheel 1104 to move to a position at the same height as the rack groove 803 on the outer side of the top pile body 801. At this time, after the meshing bar 1105 at the outer end of the rotating wheel 1104 is fixed to the rack groove 803, the second diesel engine 1103 is operated to enable the rotating wheel 1104 to drive the meshing bar 1105 to rotate. During the rotation process, the meshing bar 1105 can rotate the pile body 801 through the meshing transmission with the rack groove 803, and the pile bodies 801 can be combined into one by connecting the docking gear 802 and the wheel groove 804. This enables the entire pile body 801 to rotate when the top pile body 801 rotates. The front section of the bottom pile body 801 is connected with a drill bit 9, and the high-speed rotation of the drill bit 9 can drill and crush the obstructing stones. In addition, during the rotation of the drill bit 9, the pile body 801 is continuously pressed by the output shaft 3, so that the pile body 801 can move downward during the rotation, which makes it easier to crush the obstructing stones. During the downward movement of the pile body 801, the second diesel engine 1103 can move downward synchronously through the sliding seat 1101 in the slide groove 1102, which can effectively prevent the meshing bar 1105 from being separated from the rack groove 803. By making the pile body 801 rotate at a high speed and cooperating with stamping, it can effectively prevent the pile body 801 from being blocked by stones and being unable to move downward normally.

[0032] See also Figure 5 and Figure 7 The sampling assembly 12 includes a collection tube 1201, a sliding groove 1202 and a locking groove 1203. The sliding grooves 1202 are provided on both sides of the outside of the collection tube 1201, and the locking grooves 1203 are provided at the outer ends of the sliding grooves 1202. The sliding grooves 1202 and the locking grooves 1203 are connected to each other, and the widths of the sliding grooves 1202 and the locking grooves 1203 are consistent with the diameter of the locking pin 806.

[0033] The specific operation is as follows: after the front end pile body 801 contacts the geothermal source, the collection tube 1201 is aligned with the connecting hole 805 at the top end of the pile body 801, and the sliding groove 1202 at the outer end is aligned with the locking pin 806, so that the collection tube 1201 can be inserted into the inner side of the pile body 801. The pile bodies 801 are connected to each other, so that the connecting holes 805 on the inner sides can be connected to each other. After the collection tube 1201 is extended into the connecting hole 805 of the top end pile body 801, it can be connected to the connecting hole 805 of the bottom end pile body 801. The collecting pipe 1201 extends out from the hole 805, and can be connected to the suction equipment, so that the geothermal source can be collected after contacting with the geothermal source. By adopting the separate assembly connection between the collecting pipe 1201 and the pile body 801, the collecting pipe 1201 can be used to collect after the pile body 801 is drilled, which can effectively avoid damage caused by direct integration. The connecting hole 805 is located on the inner side of the pile body 801. During the drilling process of the pile body 801, the connecting hole 805 has less contact with the outside world, which can effectively avoid the situation that the connecting hole 805 cannot pass into the collecting pipe 1201 after the drilling is completed. After the collecting pipe 1201 passes into the inner side of the connecting hole 805, the soil blocked in the connecting hole 805 can be dredged, so that the collecting pipe 1201 can directly clean the soil in the connecting hole 805 during the process of connecting with the pile body 801, which further improves the collection stability of the equipment. After the geothermal collection is completed, the collecting pipe 1201 can be rotated to make The locking pin 806 slides from the sliding groove 1202 into the locking groove 1203. By connecting the locking pin 806 with the locking groove 1203, the multiple pile bodies 801 can be connected with the collection tube 1201, which makes the multiple pile bodies 801 can be combined into one with the collection tube 1201. By combining the multiple pile bodies 801 into one, the difficulty of extracting the pile body 801 from the soil after the geothermal source collection is completed can be greatly reduced, which makes the use of the equipment more convenient.

[0034] In summary, when the sample collection and sampling device based on geothermal exploration is used, the support seat 1 and the directional seat 10 are first placed at the drilling point where drilling is required, and then the pile body 801 to be driven into the soil is placed in the placement groove 703 inside the rotating disk 701. At this time, the hydraulic cylinder 705 works to make the engaging teeth 704 inside the placement groove 703 move toward the pile body 801, so that the engaging teeth 704 can be engaged with the rack groove 803 at the outer end of the pile body 801, which can ensure that the pile body 801 can be stably placed on the inner side of the rotating disk 701;

[0035] Then, after the pile body 801 is installed inside the rotating disk 701, the first diesel engine 6 is operated to make the rotating shaft 702 drive the rotating disk 701 to rotate, and during the rotation of the rotating disk 701, the pile body 801 can be driven to move to the same straight line as the output shaft 3. At this time, the engaging teeth 704 move backward to loosen the pile body 801, and the pile body 801 can fall to the inside of the directional seat 10, and the drill bit 9 at the front end is fitted with the ground. By working the punching machine 2, the output shaft 3 can pass through the punching hole 5 and contact the top of the pile body 801. By the punching of the punching machine 2, the pile body 801 can gradually enter the soil layer. By opening a rack groove 803 on the surface of the pile body 801 and placing the engaging teeth 704 that can engage with the rack groove 803 in the placement groove 703, the rotating The disk 701 is quickly docked with the pile body 801. After the pile body 801 is driven into the soil layer, the rotating disk 701 can be quickly connected with the second pile body 801 by engaging, and the second pile body 801 is quickly moved to the bottom end of the output shaft 3 by the rotation of the rotating disk 701 to perform the second round of pile body 801 driving operation. In addition, there are three placement grooves 703 on the rotating disk 701, which makes the loading point of the pile body 801 staggered with the position of the output shaft 3, so that the equipment can realize the driving of the pile body 801 and the loading of the pile body 801 at the same time, which can greatly improve the drilling efficiency of the equipment. At the same time, because the loading point of the pile body 801 is staggered with the output shaft 3, the equipment does not need to stop the operation of the output shaft 3 during the loading process, which further improves the drilling efficiency of the equipment.

[0036] Then, in the process of the pile body 801 overlapping with the pile body 801, the pile body 801 at the upper position can extend the docking gear 802 at its bottom into the wheel groove 804 of the pile body 801 at the lower position. The docking gear 802 is consistent with the wheel groove 804 in size, which can ensure that the two pile bodies 801 can be stably connected after overlapping, which can reduce the occurrence of drilling azimuth errors due to size deviations in the connection process between the pile bodies 801. In addition, the inner contour of the directional seat 10 is the same as the outer contour size of the pile body 801, which enables the directional seat 10 to also locate the downward movement path of the pile body 801. Through the dual positioning of the directional seat 10 and the docking gear 802 and the wheel groove 804, the drilling azimuth errors can be greatly avoided, which can effectively improve the positioning and collection accuracy of the equipment.

[0037] Then, when the pile body 801 moves downward, if it encounters a stone obstacle, the sliding seat 1101 can be loosened to make the sliding seat 1101 slide on the surface of the slide groove 1102, so that the second diesel engine 1103 can drive the rotating wheel 1104 to move to a position at the same height as the rack groove 803 on the outer side of the top pile body 801. At this time, the meshing bar 1105 at the outer end of the rotating wheel 1104 is fixed to the rack groove 803, and the second diesel engine 1103 is operated to enable the rotating wheel 1104 to drive the meshing bar 1105 to rotate. During the rotation process, the meshing bar 1105 can rotate the pile body 801 through the meshing transmission with the rack groove 803, and the pile bodies 801 can be combined into one by connecting the docking gear 802 and the wheel groove 804, which makes When the pile body 801 at the top rotates, it can drive all the pile bodies 801 to rotate. The front section of the pile body 801 at the bottom is connected to a drill bit 9. The high-speed rotation of the drill bit 9 can drill and break the blocking stones. In addition, during the rotation of the drill bit 9, the pile body 801 is continuously pressed by the output shaft 3, so that the pile body 801 can move downward during the rotation, which makes it easier to crush the blocking stones. During the downward movement of the pile body 801, the second diesel engine 1103 can move downward synchronously through the sliding seat 1101 in the slide groove 1102, which can effectively prevent the meshing bar 1105 from disengaging from the rack groove 803. By making the pile body 801 rotate at a high speed and cooperating with stamping, it can effectively prevent the pile body 801 from being blocked by stones and being unable to move downward normally.

[0038] Then, after the front end pile body 801 contacts the geothermal source, the collection tube 1201 is aligned with the connecting hole 805 at the top end of the pile body 801, and the sliding groove 1202 at the outer end is aligned with the locking pin 806, so that the collection tube 1201 can be inserted into the inner side of the pile body 801. The pile bodies 801 are butt-jointed, so that the connecting holes 805 on the inner sides can be connected to each other. After the collection tube 1201 extends into the connecting hole 805 of the top end pile body 801, it can extend out of the connecting hole 805 of the bottom end pile body 801. The collection tube 1201 can be connected to the suction equipment, so that the geothermal source can be collected after contacting the geothermal source. By adopting the separate assembly type of the collection tube 1201 and the pile body 801, the collection tube 1201 and the pile body 801 can be assembled. The connection can make the collection pipe 1201 collect after the pile body 801 is drilled, which can effectively avoid direct integration from being damaged. The connecting hole 805 is located inside the pile body 801. During the drilling process of the pile body 801, the connecting hole 805 has little contact with the outside world, which can effectively avoid the situation that the connecting hole 805 cannot be passed into the collection pipe 1201 after the drilling is completed. After the collection pipe 1201 is passed into the inside of the connecting hole 805, the soil blocked in the connecting hole 805 can be dredged, so that the collection pipe 1201 can directly clean the soil in the connecting hole 805 during the process of connecting with the pile body 801, which further improves the collection stability of the equipment.

[0039] Finally, after geothermal collection is completed, the collection tube 1201 can be rotated to make the locking pin 806 slide from the sliding groove 1202 into the locking groove 1203, and the locking pin 806 can be connected with the locking groove 1203, so that the multiple pile bodies 801 can be connected with the collection tube 1201, which makes the multiple pile bodies 801 can be combined into one with the collection tube 1201. By combining the multiple pile bodies 801 into one, the difficulty of extracting the pile body 801 from the soil after the geothermal source collection is completed can be greatly reduced, which makes the use of the equipment more convenient.
