Technical Field

[0002] With the continuous development of my country's economic level and the improvement of science and technology, industrial heating is becoming more and more common, but the pollution caused by coal-burning and electric heating is becoming more and more serious. People are now paying more attention to clean energy heating, and there is a large amount of geothermal energy on the earth. Geothermal energy is stored underground and is not affected by climatic conditions. It can be used as both basic load energy and peak load energy. From the perspective of its development and utilization cost, geothermal energy has more development potential than other renewable energy sources. Geothermal energy as a clean energy is receiving increasing attention from all over the world, but geothermal energy is unevenly distributed and difficult to collect, and the technology of geothermal detection is gradually improving.

[0003] At present, geothermal detection devices are needed when searching for geothermal resources. At present, most geothermal detection devices used for geological exploration generally detect by measuring infrared on the surface through sensors. However, the infrared generated by the heat emitted by some geothermal resources cannot be transmitted to the ground due to the obstruction of the surface soil, making it impossible for ordinary detectors to detect and lose the opportunity to exploit geothermal resources. Therefore, geothermal deep underground needs to be detected by drilling. After drilling, if the drill rod is pulled out and the detection equipment is extended into the ground again, it is easy to get lost in the borehole for soft locations, affecting the detection effect. For this reason, we propose a geothermal detection device for geological exploration. Summary of the invention

DETAILED DESCRIPTION

[0025] 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. Example

[0026] See also Figure 1-Figure 3 The figure shows a geothermal detection device for geological exploration, comprising a rotating casing 1, a drill bit 2 is fixed at the bottom end of the rotating casing 1, a plurality of detection ports 3 are opened at equal angles on the rotating casing 1, and a docking rod 4 rotatably mounted on the drill bit 2, a soil discharge assembly 5 for transporting soil out of the rotating casing 1 is installed on the outer side of the docking rod 4, and a detection mechanism 6 for geothermal detection is installed on the outer side of the docking rod 4.

[0027] It should be noted that in this solution, the outer end of the designed rotating casing 1 is driven to rotate downward by the existing rotating equipment, so that the drill bit 2 at the bottom can be used for drilling operations. At the same time, the designed drill bit 2 is also provided with drainage holes for soil discharge, so that the soil can enter the rotating casing 1 when drilling and be discharged using the soil discharge assembly 5.

[0028] See also Figure 2-Figure 4 The soil discharge assembly 5 shown in the figure includes an outer cylinder 7 threadedly sleeved on the docking rod 4, a plurality of limit bars 8 adapted to the detection port 3 are fixed on the outer side of the outer cylinder 7, and an inner cylinder 9 is fixed inside the outer cylinder 7, a rotating cylinder 10 is rotatably installed between the outer cylinder 7 and the inner cylinder 9, and an inner gear ring 11 is fixed on the top of the rotating cylinder 10, a spiral blade 12 is fixed on the outer side of the rotating cylinder 10, and a driving member 13 is installed on the top of the outer cylinder 7;

[0029] It should be noted that: the docking rod 4 is driven to rotate by an external rotating device, so that the outer cylinder 7 can move up and down with the rotation of the docking rod 4. When it moves down to above the discharged soil, the spiral blade 12 is driven to rotate by the driving member 13, so that the discharged soil can be sucked into the rotating cylinder 10, and the outer cylinder 7 is moved out by reversing the docking rod 4 to realize the discharge of the soil. After repeating this several times, the residual soil in the rotating sleeve 1 can be removed, which is convenient for subsequent detection.

[0030] Among them, see Figure 4 The driving member 13 shown in the figure includes a driving motor 14 fixed to the top of the outer cylinder 7 through a motor frame, and a driving gear 15 is fixed to the output end of the driving motor 14 through a coupling. A through opening is opened at the top of the inner cylinder 9, and the driving gear 15 is located in the through opening and meshes with the inner gear ring 11;

[0031] It should be noted that the driving motor 14 rotates to drive the driving gear 15 to rotate, thereby causing the inner gear ring 11 to rotate, driving the rotating cylinder 10 to rotate, so that the spiral blades 12 can rotate synchronously to suck in the soil.

[0032] Also, see Figure 5 and Figure 6 The detection mechanism 6 shown in the figure includes a docking sleeve 16 and an adjustment sleeve 17 which are slidably sleeved on the outside of the docking rod 4, a mounting opening 18 is opened in the docking sleeve 16, and a limiting member 19 is installed in the mounting opening 18, a mounting opening 20 is opened in the adjustment sleeve 17, and an adjusting member 21 is installed in the mounting opening 20, a docking plate 22 is rotatably installed at the bottom end of the docking sleeve 16, and an adjusting plate 23 rotatably connected to the adjusting sleeve 17 is rotatably installed at the outer end of the docking plate 22, a detector 24 for geothermal infrared detection is installed on the docking plate 22, a limiting opening 25 is opened on the outside of the docking sleeve 16, and a limiting rail 26 adapted to the limiting opening 25 is fixed to the inner wall of the inner cylinder 9;

[0033] It should be noted that: by changing the angle between the adjustment plate 23 and the docking plate 22, the detector 24 on the docking plate 22 can be moved to the vicinity of the inner wall of the rotating casing 1, and infrared detection is performed through the soil in the detection port 3, so that the soil geothermal can be detected.

[0034] Also, see Fig. 9 The limiting member 19 shown in the figure includes an electric push rod 27 fixed in the installation port 18, a limiting tooth 28 is fixed at the output end of the electric push rod 27, and a plurality of limiting grooves 29 are opened at equal intervals on the outer side of the docking rod 4, and the limiting tooth 28 is engaged with the limiting groove 29;

[0035] It should be noted that: when the electric push rod 27 is extended and retracted, the limit tooth 28 is inserted into the limit groove 29, thereby limiting the docking sleeve 16, and by engaging with the limit groove 29 at different positions, the geothermal detection at different positions on the docking rod 4 is met.

[0036] Also, see Figure 8 The adjusting member 21 shown in the figure includes a telescopic rod 30 fixed in the second mounting opening 20, a threaded piece 31 threadedly connected to the outer side of the docking rod 4 is fixed on the outer side of the telescopic rod 30, and a compression spring 32 for pushing the threaded piece 31 outward is sleeved on the outer side of the telescopic rod 30;

[0037] It should be noted that: the designed threaded piece 31 is threadedly connected with the docking rod 4, so that the docking rod 4 can be threadedly connected with it when rotating, driving the adjustment sleeve 17 to move its position. At the same time, after the adjustment sleeve 17 moves to the limit position, the docking rod 4 continues to rotate. At this time, under the action of the telescopic rod 30, the push threaded piece 31 is moved outward, and the adjustment sleeve 17 is not driven to continue to move, making the adjustment of the adjustment plate 23 more convenient.

[0038] The principle of avoiding getting lost in drilling: First, the personnel drive the rotating casing 1 to rotate through the equipment, and use the drill bit 2 to press down into the soil. After moving down to the specified depth, the personnel then drive the docking rod 4 to rotate through the rotating equipment, so that the outer cylinder 7 and the inner cylinder 9 move down to the soil in the rotating casing 1, and then drive the motor 14 to rotate, drive the spiral blade 12 to rotate, and roll the soil in. Then, the docking rod 4 is reversed, and the outer cylinder 7 and the like are moved out to discharge the soil. Then, the operation is repeated until there is no excessive soil in the channel, and the channel is supported by the rotating casing 1 to prevent collapse;

[0039] At the beginning, when the outer cylinder 7 is rotated and moved downward by the docking rod 4, the docking sleeve 16 and the adjusting sleeve 17 will follow and move downward in the inner cylinder 9. After reaching the specified position, the electric push rod 27 drives the limiting tooth 28 to engage with the limiting groove 29, so that the docking sleeve 16 is limited. Then, when the outer cylinder 7 is rolled up with enough soil to be discharged and moved outward, the docking sleeve 16 is limited by the limiting opening 25 and the limiting rail 26, and the adjusting sleeve 17 will move upward with the rotation of the docking rod 4. By expanding the adjusting plate 23, the The docking plate 22 is opened, so that the detector 24 located on the docking plate 22 moves to the inner wall of the rotating sleeve 1, so that geothermal detection of the soil at the inner wall is carried out. After that, when the outer cylinder 7 moves downward, the limit rail 26 and the limit opening 25 are docked, and then the outer cylinder 7 continues to move downward, at this time it will drive the adjustment sleeve 17 to move downward, and then move to the soil below, and then carry out soil discharge and geothermal detection again, and the cyclic detection can carry out multiple detections at different depths in the channel, and the detection is more specific. Example

[0040] See also Figure 7 This embodiment further explains Example 1. The adjustment plate 23 shown in the figure includes two docking platforms 34 that are rotatably docked with the outer end of the docking plate 22 and the top of the adjustment sleeve 17, wherein a support rod 35 is fixed to the outer side of one of the docking platforms 34, and a connecting rod 36 is slidably inserted at the outer end of the support rod 35, the outer end of the connecting rod 36 is fixed to the other docking platform 34, and an adjustment spring 37 is sleeved on the outer side of the connecting rod 36.

[0041] It should be noted that: through the interaction between the designed adjustment spring 37 and the connecting rod 36, the adjustment plate 23 itself has a certain contractility, and also allows the adjustment plate 23 to have a certain buffer space when adjusting the docking plate 22, making the adjustment more convenient. Example

[0042] See also Figure 5 This embodiment further illustrates other embodiments. A docking sleeve 33 is fixed inside the outer sleeve 7 shown in the figure, and the docking sleeve 33 is threadedly sleeved with the docking rod 4.

[0043] It should be noted that: through the designed docking tube 33, the threaded connection area between the docking rods 4 is increased, making the movement and adjustment more stable.
