Description

Technical Field

[0001] This utility model belongs to the field of geothermal exploration technology, and specifically relates to a temperature measuring device for geothermal exploration. Background Technology

[0002] Geothermal exploration is the core link in identifying, assessing and developing geothermal resources, involving multiple disciplines such as geology, geophysics, geochemistry, and engineering. Temperature measurement devices in geothermal exploration are key tools for assessing the potential of geothermal resources. They need to be adaptable to high-temperature environments from the surface to deep underground (from normal temperature to above 500℃) and cover both short-term monitoring and long-term dynamic tracking.

[0003] Existing temperature measurement devices for geothermal exploration fix their position by inserting a pin into the soil at the base. A motor controls the rotation of a rotating rod, which is then driven by a hydraulic system to insert into the soil. A drill bit with temperature and humidity sensors at the lower end of the rotating rod penetrates the soil to detect temperature and humidity data. However, in actual use, when the rotating rod drives the drill bit to insert into the soil, the operation of the upper motor and other drive structures can easily cause the base to vibrate. This vibration may cause the pin inserted into the soil to loosen, affecting the fixation of the base and potentially causing a partial displacement of the base's position, which could then affect the measurement results. Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of the prior art by providing a temperature measuring device for geothermal exploration. Before temperature measurement, the pin on the base can be firmly and stably inserted into the soil, which can effectively prevent the pin from loosening and ensure that the base is stably fixed on the ground, thus preventing errors in subsequent temperature measurements.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a temperature measuring device for geothermal exploration, including a support frame, multiple fixed platforms arranged on the outside of the support frame, a guide seat arranged inside each fixed platform, a sliding rod slidably arranged inside each guide seat, a positioning bolt arranged at the bottom end of each sliding rod, and multiple sliding plates slidably arranged inside each positioning bolt; a partition plate is arranged on the upper side of each positioning bolt, and symmetrically distributed sliding columns are arranged between the partition plate and the bottom end of the positioning bolt, and symmetrically distributed drive seats are slidably arranged between the sliding columns, and multiple connecting rods are rotatably arranged on the outside of each drive seat, and the connecting rods are rotatably connected to adjacent sliding plates respectively; a double-acting screw is rotatably arranged between the partition plate and the bottom end of the positioning bolt, and the drive seat is threadedly connected to the double-acting screw; a second motor is arranged on each partition plate, and the output shaft of the second motor is fixed to the double-acting screw through a coupling.

[0006] As a further improvement of this utility model, the upper surface of the fixed platform is provided with hydraulic rods II, and the support is provided with symmetrically distributed hydraulic control boxes II. The hydraulic rods II are all connected and fixed to the adjacent hydraulic control boxes II. The support is provided with symmetrically distributed guide rails, and a movable platform is slidably arranged between the guide rails. A drill rod is rotatably arranged at the lower end of the movable platform. A temperature sensor and a humidity sensor are arranged at the bottom of the drill rod. A motor I is arranged on the upper surface of the movable platform, and the output shaft of the motor I is fixed to the drill rod by a coupling.

[0007] As a further improvement of this utility model, the upper end of the bracket is provided with multiple hydraulic rods, the telescopic ends of which are all connected and fixed to the movable platform. A hydraulic control box is provided on the bracket, and the hydraulic rods are all connected to the hydraulic control box.

[0008] As a further improvement of this utility model, a control panel is provided on the outside of the bracket, and the temperature sensor, humidity sensor, motor one, motor two, hydraulic control box one and hydraulic control box two are all electrically connected to the control panel.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] Firstly, the control panel regulates the operation of the hydraulic control box 2, which in turn controls the operation of the hydraulic rod 2. This causes the telescopic end of the hydraulic rod 2 to slide between the slide rod and the guide seat, thereby causing the slide rod to drive the positioning bolt into the soil.

[0011] Secondly, the control panel regulates the operation of motor 2. Through the threaded relationship between the two-way lead screw and the drive seat, the drive seats on both sides move in opposite directions, causing the drive seat and the connecting rod to rotate, and the connecting rod and the sliding plate to rotate, so that the sliding plate can quickly and stably extend out of the positioning bolt.

[0012] Third, by increasing the contact area between the sliding plate and the positioning bolt, the contact area with the ground can be effectively prevented from loosening between the positioning bolt and the soil, thus ensuring that the base is stably fixed on the ground and preventing errors in subsequent temperature measurements.

[0013] Fourth, the temperature sensor, humidity sensor, motor 1, and hydraulic control box 1 are controlled by the control panel. The temperature and humidity in the soil are detected by the temperature sensor and humidity sensor at the bottom of the drill rod, which facilitates temperature measurement in geothermal exploration.

Detailed Implementation

[0020] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0021] like Figure 2 , 3 As shown, the system includes a bracket 101, with multiple fixed platforms 201 on the outer side of the bracket 101. Each fixed platform 201 has a guide seat 202 inside, and each guide seat 202 has a sliding rod 203 inside. Each sliding rod 203 has a positioning bolt 204 at its bottom end, and each positioning bolt 204 has multiple sliding plates 207 inside. Each fixed platform 201 has a hydraulic rod 206 on its upper surface, and each bracket 101 has symmetrically distributed hydraulic control boxes 205. Each hydraulic rod 206 is connected and fixed to an adjacent hydraulic control box 205.

[0022] like Figure 1 , 4As shown, the support 101 is provided with symmetrically distributed guide rails 102, and a movable platform is slidably arranged between the guide rails 102. A drill rod 103 is rotatably arranged at the lower end of the movable platform. A temperature sensor and a humidity sensor are arranged at the bottom of the drill rod 103. A motor 104 is arranged on the upper surface of the movable platform. The output shaft of the motor 104 is fixed to the drill rod 103 by a coupling. Multiple hydraulic rods 105 are arranged at the upper end of the support 101. The telescopic ends of the hydraulic rods 105 are all connected and fixed to the movable platform. A hydraulic control box 106 is arranged on the support 101. All hydraulic rods 105 are connected to the hydraulic control box 106.

[0023] like Figure 3 , 4 As shown, each of the positioning bolts 204 has a partition plate 211 on its upper inner side. Symmetrically distributed sliding columns 205 are provided between the partition plate 211 and the bottom inner end of the positioning bolt 204. Symmetrically distributed drive seats 209 are slidably arranged between the sliding columns 205. Multiple connecting rods 210 are rotatably arranged on the outer side of each drive seat 209, and the connecting rods 210 are rotatably connected to adjacent sliding plates 207. A bidirectional lead screw 212 is rotatably arranged between the partition plate 211 and the bottom inner end of the positioning bolt 204. Each drive seat 209 is threadedly connected to the bidirectional lead screw 212. A second motor 213 is provided on each partition plate 211, and the output shaft of the second motor 213 is fixed to the bidirectional lead screw 212 via a coupling.

[0024] like Figure 1 , 2 As shown, a control panel 301 is provided on the outside of the bracket 101. The temperature sensor, humidity sensor, motor 104, motor 213, hydraulic control box 106 and hydraulic control box 205 are all electrically connected to the control panel 301.

[0025] In actual use, after the bracket 101 is moved to a suitable position, the control panel 301 regulates the operation of the hydraulic control box 205, which in turn controls the hydraulic rod 206. This causes the telescopic end of the hydraulic rod 206 to slide between the slide rod 203 and the guide seat 202, thereby causing the slide rod 203 to drive the positioning bolt 204 to insert into the soil. Then, the control panel 301 regulates the operation of the motor 213, causing the output shaft of the motor 213 to drive the bidirectional lead screw 212 connected to it to rotate, thereby driving the bidirectional lead screw 212 to rotate. The threaded relationship between the lead screw 212 and the drive seat 209 causes the drive seats 209 on both the upper and lower sides to move in opposite directions, causing the drive seat 209 to rotate with the connecting rod 210 and the sliding plate 207 to rotate. This causes the sliding plate 207 to extend out of the positioning bolt 204. The cooperation between the sliding plate 207 and the positioning bolt 204 increases the contact area with the ground, which can effectively prevent the positioning bolt 204 from loosening with the soil and keep the base stably fixed on the ground, preventing errors in subsequent temperature measurements.

[0026] The temperature sensor, humidity sensor, motor 104, and hydraulic control box 106 are controlled by the control panel 301. The output shaft of motor 104 drives the drill rod 103 connected to it to rotate. Then, the hydraulic control box 106 controls the extension end of the hydraulic rod 105 to extend, driving the rotating drill rod 103 to insert into the soil. The temperature and humidity in the soil are then detected by the temperature sensor and humidity sensor at the bottom of the drill rod 103, which facilitates temperature measurement in geothermal exploration.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
