Description

Technical Field

[0001] The present application relates to the technical field of geothermal exploration, and in particular to a geothermal exploration temperature detector. Background Technique

[0002] Geothermal temperature refers to the temperature at a certain depth below the Earth's surface. Measuring geothermal temperature is of great significance for fields such as geological exploration, geothermal resource development, and utilization of groundwater resources. Methods for measuring geothermal temperature include borehole temperature measurement method, heat flow temperature measurement method, seismic temperature measurement method, and geoelectric temperature measurement method. Among them, the measurement accuracy of the heat flow temperature measurement method is relatively low, while the seismic temperature measurement method and the geoelectric temperature measurement method require the deployment of seismographs or electrodes, with high costs. Therefore, the borehole temperature measurement method is usually used to measure geothermal temperature.

[0003] In the patent with the authorized publication number CN219608273U, the temperature detector for geothermal exploration includes a fixed cylinder, a wire winding wheel, a connecting wire, an installation cylinder, a driving motor, a drill bit, and a temperature sensor, etc. The connecting wire is wound around the wire winding wheel so that the wire winding wheel can rotate to wind and unwind the connecting wire. The installation cylinder is slidably connected to the fixed cylinder and can slide up and down. Driving motors are symmetrically connected up and down inside the installation cylinder. The drill bit is connected to the output shaft of the driving motor through a coupling to drive the drill bit to rotate and drill holes in the ground. A temperature sensor for measuring geothermal temperature is installed inside the installation cylinder. By driving the drill bit to rotate through the driving motor, the present utility model can drill holes on the ground, thereby driving the temperature sensor to move downward into the ground. The geothermal temperature can be measured through the temperature sensor. In this way, it can ensure that the temperature sensor can reach the specified depth of the ground, the measurement data is relatively accurate, and the operation steps are reduced, improving work efficiency.

[0004] When the above device is implemented, it is not convenient for protective operations. A large amount of soil will splash during the drilling process of the drill bit, and the lack of protection will cause the soil to splash randomly onto the staff and the equipment, easily resulting in dirty clothes and equipment damage. Therefore, the present application proposes a geothermal exploration temperature detector to solve the above problems. Utility Model Content

The other end of the suspension rope 20 is fixedly connected to a temperature sensor 21. A pressure sensor 22 is fixedly assembled at the bottom of the temperature sensor 21.

[0028] Referring to Figure 1 and Figure 2, the frame 1 is made of magnetic material. There are two fixing plates 2, and the other fixing plate 2 is also fixedly assembled at the outer side of the frame 1. The bottom of the winding roller 4 is rotatably connected to the top of the fixing plate 2, so that the magnetic strip 6 can be placed at the inner wall position of the card slot 7, and then the transparent protective curtain 5 can be unfolded at the outer side of the frame 1, so as to play a protective role for the opening of the frame 1 and ensure that the soil will not splash onto the staff randomly during drilling.

[0029] Refer to Figure 1 and Figure 4 , a controller 8 is fixedly assembled on the outer side of the frame 1. The controller 8 is electrically connected to the temperature sensor 21 and the pressure sensor 22, and the controller 8 is also electrically connected to the external display screen, so that when the pressure sensor 22 moves to the bottom of the hole diameter and collides with the soil, it can timely transmit the signal to the controller 8, and then it can be displayed on the display screen. At the same time, it can be reflected that the temperature sensor 21 has moved to the bottom position of the hole diameter, and the temperature survey operation can be carried out.

[0030] Refer to Figure 3 , there are two square grooves 9, and the two square grooves 9 are symmetrically arranged at the inner side of the frame 1. The slider 12 is slidably connected to the inner wall of one square groove 9, and a limiting rod 14 is fixedly assembled at the inner wall position of the other square groove 9. The outer edge of the limiting rod 14 is slidably connected with a limiting block 15, and the outer side of the limiting block 15 is fixedly connected to the side of the connecting plate 13 away from the slider 12. A servo motor 16 is fixedly assembled on the top of the connecting plate 13, and the power output shaft of the servo motor 16 is fixedly connected with a drill bit 17, so as to play a positioning role for the connecting plate 13 and the drill bit 17 when moving up and down, and then ensure the stability of the connecting plate 13 and the drill bit 17 when moving up and down, and will not randomly tilt and deviate.

[0031] Refer to Figure 5 , four cylinders 23 are fixedly assembled on the inner wall of the frame 1, and the power output shafts of the four cylinders 23 are all fixedly assembled with moving wheels 24, so that when moving is needed, the cylinders 23 can be driven to drive the moving wheels 24 to move downward, and then the moving wheels 24 can be used to drive the device to move, so that the staff does not need to carry the device. When drilling is needed, the moving wheels 24 can be received at the inner wall position of the frame 1 to ensure that the bottom of the frame 1 is in contact with the soil ground and ensure stability.

[0032] Refer to Figure 3 and Figure 5 , the slider 12 is slidably connected to the inner wall of the square groove 9, and a bearing is fixedly assembled at the inner bottom of the square groove 9. The bottom end of the lead screw 11 is fixedly connected to the inner wall of the bearing, so as to play a limiting role for the rotating lead screw 11, ensure its stability during rotation, and ensure that it will not randomly shift and shake in position.

[0033] Working principle: When using this device, first, the air cylinder 23 can be driven to drive the moving wheel 24 to move downward, and then the moving wheel 24 can be used to drive the device to move, so that there is no need for staff to carry the device. When drilling is required, the moving wheel 24 can be retracted to the inner wall position of the frame 1 to ensure that the bottom of the frame 1 is in contact with the soil ground to ensure stability. Then, the motor two 10 can be driven to drive the lead screw 11 to rotate, and then drive the slider 12 and the connecting plate 13 to move downward until the bottom of the drill bit 17 is in contact with the soil. At this time, the magnetic strip 6 can be placed at the inner wall position of the card slot 7 and connected by the magnetic attraction principle. Then, the transparent protective curtain 5 can be unfolded at the outer side position of the frame 1, so as to protect the opening of the frame 1 and ensure that the soil will not splash onto the staff's body randomly during drilling. At the same time, the servo motor 16 can be driven to drive the drill bit 17 to rotate for drilling operations. When the drilling is completed, the frame 1 can be slightly moved until the position of the pressure sensor 22 corresponds to the aperture position. At this time, the motor three 18 can be driven to drive the winding wheel 19 to rotate in the reverse direction, so that the pressure sensor 22 can be placed at the inner wall position of the aperture until the pressure sensor 22 collides with the soil, and the signal can be transmitted to the controller 8 in time and then displayed on the display screen. At the same time, it can be reflected that the temperature sensor 21 has moved to the bottom position of the aperture and temperature detection operations can be carried out without manual operation by the staff. After the temperature measurement is completed, the motor three 18 can be driven again to wind the lifting rope 20 to the inner wall position of the winding wheel 19, and the temperature sensor 21 and the pressure sensor 22 can be taken out of the aperture to complete the temperature measurement operation.
