[0038] Reference Figure 1 In use, rotate the heat insulation cover 205 to separate it from the threaded groove 101, and then rotate the heat insulation cover 205 to separate it from the heat insulation housing 201. After turning on the machine by pressing the switch button 209, screw the heat insulation cover 205 and the heat insulation housing 201 together. Then, fasten the safety buckle 104 and the hanging ring 206 together. Place the testing mechanism 2 in the geothermal well, and then rotate the handwheel 107 to drive the reel 1 to rotate. When the reel 1 rotates, the rope 102 is released, which causes the testing mechanism 2 to sink into the geothermal well. The water temperature data measured by the temperature probe 203 is transmitted to the control unit. The mainboard controls the data storage in the memory. After the measurement is completed, the rope 102 is wound up by the reel 1 to remove the test mechanism 2 from the geothermal well. Then, the heat insulation protective shell 201 is rotated to separate the heat insulation protective shell 201 from the heat insulation protective cover 205. The temperature data stored in the memory can be read by connecting the existing reading device and the data reading interface 208. After use, the heat insulation protective shell 201 and the heat insulation protective cover 205 are screwed together. Then, the heat insulation protective shell 201 is inserted into the threaded groove 101, and the heat insulation protective cover 205 is screwed together with the threaded groove 101.
