[0024] Reference Figure 1 and Figure 2 The utility model provides an embodiment of a drilling connection testing device, comprising a base 1, an adjusting mechanism 2 and a positioning mechanism 3, wherein the base 1 comprises a bracket 102, the adjusting mechanism 2 comprises an electric lifting rod 201, and the positioning mechanism 3 comprises a bracket 301, wherein the lower end center of the electric lifting rod 201 is fixedly set to the upper end center of the bracket 102, a turntable 202 is fixedly set on the upper end of the electric lifting rod 201, a slide plate 203 is provided on the upper end center of the turntable 202 via a rotating shaft, a U-shaped frame 204 is slidably provided on the upper end of the slide plate 203, and a bracket 301 is provided between the inner walls on both sides of the U-shaped frame 204 via a rotating shaft;

[0025] Specifically, the bracket 102 in the base 1 provides a good installation position for the electric lifting rod 201 in the adjustment mechanism 2 , and the U-shaped frame 204 in the adjustment mechanism 2 provides a good installation position for the bracket 301 in the positioning mechanism 3 .

[0026] Reference Figure 2 、 Figure 3 、 Figure 4 and Figure 5 : The lower end of the bracket 102 is fixedly provided with a base plate 101, and four brake universal wheels 103 are fixedly provided with an axisymmetric position near the edge of the lower end of the base plate 101. Hydraulic rods 205 are fixedly provided at the front and rear positions of the middle of the upper bottom surface of the lower end of the U-shaped frame 204. The upper ends of the two hydraulic rods 205 are respectively fixed to the front and rear positions of the middle of the lower end of the bracket 301. A liquid pipe 206 is fixedly provided between the lower positions of the two hydraulic rods 205, and a liquid valve 207 is fixedly provided at the middle position of the liquid pipe 206.

[0027] Specifically, by fixing the base plate 101 at the lower end of the bracket 102 and axially symmetrically arranging four brake universal wheels 103 at the edge of the lower end of the base plate 101, the stable movement and placement of the device can be achieved. When in use, according to actual needs, the liquid valve 207 can be opened, and then the bracket 301 is adjusted to an appropriate pitch angle, and the two hydraulic rods 205 connected therebetween are extended and retracted accordingly, and then the liquid valve 207 is closed. The two hydraulic rods 205 can no longer exchange liquid, and their respective lengths are also determined, thereby fixing the pitch angle of the bracket 301 well. Finally, the infrared detector clamped inside the bracket 301 can be quickly and accurately adjusted to the appropriate pitch angle when performing a drilling connectivity test, and can be stably maintained, thereby improving the efficiency and accuracy of the test.

[0028] Reference Figure 2 、 Figure 3 、 Figure 4 and Figure 5 : Slide rods 303 are slidably provided at the centers of both sides of the bracket 301, and square plates 302 are fixedly provided at the centers of the outer sides of the two slide rods 303. The inner sides of the two square plates 302 near the four corners are fixedly connected to the middle positions of both sides of the bracket 301 through connecting rods. Round plates 305 are fixedly provided on the rod bodies of the two slide rods 303 near the positions on both sides of the bracket 301. Return springs 304 are fixedly provided between the two round plates 305 and the two square plates 302. A splint 306 is fixedly provided at the center of one end of the two slide rods 303.

[0029] Fixed plates 307 are fixedly provided at both sides of the upper middle and lower front ends of the bracket 301. The three fixed plates 307 are arranged symmetrically with respect to the center. A first spring damper 308 is fixedly provided at the center of one side of the three fixed plates 307, and a second spring damper 309 is fixedly provided at the center of the other side of the three fixed plates 307. A first positioning plate 310 is fixedly provided at one end of the three first spring dampers 308, and a second positioning plate 311 is fixedly provided at one end of the three second spring dampers 309.

[0030] Specifically, when the infrared detector is placed inside the bracket 301, the two clamping plates 306 are squeezed and move outward, pushing the two sliding rods 303 to slide outward. The two circular plates 305 fixed to the rods of the two sliding rods 303 move accordingly and compress the two return springs 304, thereby firmly clamping the infrared detector through the two clamping plates 306.

[0031] When detecting a borehole with a smaller aperture, the three second positioning plates 311 can be extended into the borehole along the edge of the borehole, and the three second spring dampers 309 are stretched accordingly, and the three second positioning plates 311 are stably pressed against the hole wall, thereby well controlling the detection direction of the infrared detector to be parallel to the borehole axis. Similarly, when detecting a borehole with a larger aperture, the three first positioning plates 310 can be extended into the borehole along the edge of the borehole, and the three first spring dampers 308 are compressed accordingly, and the three first positioning plates 310 are stably pressed against the hole wall, thereby well controlling the detection direction of the infrared detector to be parallel to the borehole axis.

[0032] Working principle: When in use, according to actual needs, the liquid valve 207 can be opened, and then the bracket 301 is adjusted to an appropriate pitch angle. The two hydraulic rods 205 connected thereto will then extend and retract. Then the liquid valve 207 is closed. The two hydraulic rods 205 can no longer exchange liquid, and their respective lengths are also determined, thereby well fixing the pitch angle of the bracket 301. Ultimately, when conducting a borehole connectivity test, the infrared detector clamped inside the bracket 301 can be quickly and accurately adjusted to an appropriate pitch angle and can be stably maintained, thereby improving the efficiency and accuracy of the test.

[0033] Secondly, when the infrared detector is placed inside the bracket 301, the two clamping plates 306 are squeezed and moved outward, pushing the two sliding rods 303 to slide outward, and the two circular plates 305 fixed on the rod bodies of the two sliding rods 303 move accordingly and compress the two return springs 304, so that the infrared detector is well and stably clamped by the two clamping plates 306. When detecting a borehole with a smaller aperture, the three second positioning plates 311 can be extended into the borehole along the edge of the borehole, and the three second spring dampers 309 are stretched accordingly, and the three second positioning plates 311 are stably pressed against the hole wall, so as to well control the detection direction of the infrared detector to be parallel to the borehole axis. Similarly, when detecting a borehole with a larger aperture, the three first positioning plates 310 can be extended into the borehole along the edge of the borehole, and the three first spring dampers 308 are compressed accordingly, and the three first positioning plates 310 are stably pressed against the hole wall, so as to well control the detection direction of the infrared detector to be parallel to the borehole axis.
