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.

[0033] The pipe reflector for geological exploration of the present invention comprises:

[0034] The upper cover 1 is provided with a first connection portion 11 connected to the power head of the exploration equipment; in this embodiment, the power head of the exploration equipment is threadedly connected to the first connection portion 11, and the first connection portion 11 is provided with a thread that is consistent with the rotation direction of the power head of the exploration equipment. Generally, the power head of the exploration equipment rotates clockwise, and the first connection portion 11 is a right-handed tapered pipe thread.

[0035] The planetary reduction mechanism 2 includes an inner gear ring 21 and a sun gear shaft 22 arranged at the center of the inner gear ring 21. A plurality of centrosymmetrical planetary gear shafts 23 are arranged between the inner gear ring 21 and the sun gear shaft 22. In this embodiment, there are three centrosymmetrical planetary gear shafts 23.

[0036] A lower cover 3, wherein the lower cover 3 is provided with a middle hole 31 extending from the lower part of the sun gear shaft 22;

[0037] The inner gear ring 21 is fixedly connected to the upper cover 1 and the lower cover 3. The upper cover 1 and the lower cover 3 are provided with a first mounting hole 12 of the planetary gear shaft 23. The upper cover 1 is also provided with a second mounting hole 13 at the upper end of the sun gear shaft 22.

[0038] A detachable tap or joint 24 is provided at the end of the sun gear shaft 22. In this embodiment, the joint 24 is threadedly connected to the end of the sun gear shaft 22. The thread at the end of the joint 24 is opposite to the thread direction of the first connecting part 11. The joint 24 is a left-handed tapered pipe thread joint.

[0039] In this embodiment, a plurality of positioning pins 25 and bolts 26 are disposed between the upper cover 1 and the inner gear ring 21 , and a plurality of positioning pins 25 and bolts 26 are disposed between the lower cover 3 and the inner gear ring 21 .

[0040] A skeleton oil seal 4 is provided between the lower portion of the sun gear shaft 22 and the middle hole 31 .

[0041] In this embodiment, the sun gear shaft 22 and the planetary gear shaft 23 are carburized and quenched: surface hardness 58-63HRC, hardened layer 0.4-0.6, core hardness 30-45HRC, the inner gear ring 21 is tempered: hardness 26-30BRC, nitrided: surface hardness ≥550HY compound layer ≥0.5.

[0042] Working principle:

[0043] During the geological exploration process, if the casing is broken or the lower end of the drill rod is loosened, there is no thread at the broken part of the casing, and the thread at the lower end of the drill rod can no longer be used. At this time, the geological exploration pipe reverser described in the present invention is used. For example, the power head of the exploration equipment generally outputs power in a clockwise direction, and the first connecting part 11 is a right-handed tapered pipe thread. The power head of the exploration equipment is tightly combined with the first connecting part 11 through the right-handed tapered pipe thread. The clockwise rotation is converted into counterclockwise rotation of the sun gear shaft 22 through the planetary reduction mechanism 2. A tap is first installed at the lower end of the sun gear shaft 22 to machine a left-handed thread on the casing or the drill rod, and then the tap is removed, and the joint 24 is installed on the lower end of the sun gear shaft 22. Under the counterclockwise rotation of the sun gear shaft 22, the joint 24 is tightly combined with the casing or the drill rod, and finally the broken casing or the loosened drill rod is lifted and taken out, and the power head of the exploration equipment can be installed with a new casing to continue to work normally, which greatly saves energy, materials, manpower, material resources, time and money.

[0044] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
