[0002] Geological exploration refers to the systematic investigation, observation, analysis and evaluation of the geological structure, geological features, geological properties and underground resources on the earth's surface and its lower part. It is an important branch of geology, aiming to obtain information about the internal structure of the earth, rock composition, topographic features, underground water resources, mineral resources, etc.

[0003] During the geological exploration process, the surveying rod is used to mark the position and elevation of the measurement point. The surveyor can erect the surveying rod at the location to be measured, and then measure its position coordinates and elevation through instruments.

[0004] However, during the calibration process of the surveying rod, due to the different environments of the calibration areas, when calibrating the surveying rod in some areas with relatively hard geology, people often need to repeatedly twist the surveying rod to fully insert it into the geology. However, it is difficult to exert force when twisting the wrist to insert the surveying rod, which will thus affect the calibration efficiency of the surveying rod. Therefore, a surveying rod for geological exploration is proposed to solve the above problems. Content of the Utility Model

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Refer to Figure 1 - Figure 3 As shown in the figure, an embodiment provided by the present utility model: A surveying rod for geological survey includes a base 1. A support leg 5 is provided on the outer arc surface of the base 1. An auxiliary positioning device 3 is provided inside the support leg 5. A boosting device 2 is provided on the upper surface of the base 1. A surveying rod 4 is threadedly connected to the inner arc surface of the base 1;

[0026] The boosting device 2 includes a bearing 204. The upper end of the bearing 204 is fixedly connected to a multi-layer telescopic rod 203. The upper end of the multi-layer telescopic rod 203 is fixedly connected to a rotating block 202. A threaded rod 206 is threadedly connected inside the rotating block 202. One end of the threaded rod 206 is rotatably connected to a clamping block 205. The end of the threaded rod 206 away from the clamping block 205 is fixedly connected to a boosting rod 201.

[0027] An annular groove is provided on the upper surface of the base 1, so that the bearing 204 can be accommodated therein. A threaded groove is provided on the inner arc surface of the base 1, so that it can form a threaded connection with the threaded protrusion on the outer arc surface of the survey rod 4. A through hole is provided at the upper end of the inner surface of the support leg 5, so that its hinge shaft can be accommodated. The upper end of the inner surface of the support leg 5 is provided as an arc surface. When this arc surface contacts the linkage rod 304, it can squeeze the two groups of linkage rods 304 to move towards each other, and drive the auxiliary rod 302 outside the linkage rod 304 to retract into the insertion rod 303. A rectangular chute is provided on the outer surface of the support leg 5, so that the pull rod 301 can be accommodated and slide therein. A cylindrical groove is provided at the lower part of the inner surface of the support leg 5. The upper end of the survey rod 4 is provided with a threaded protrusion. The outer arc surface of the bearing 204 is fixedly connected to the base 1. Through holes are provided at both the left and right ends of the outer arc surface of the rotating block 202. A threaded groove is provided on the inner surface of the rotating block 202 through the inner side of the through hole, so that the rotating block 202 can form a threaded connection with the threaded rod 206. A rubber pad is provided on the inner arc surface of the clamping block 205, so that the friction between it and the survey rod 4 is relatively large when they contact. Multiple elliptical protrusions are provided on the outer arc surface of the force application rod 201, so as to reduce the occurrence of slipping when people twist the force application rod 201.

[0028] Refer to Figure 1 , Figure 4 and Figure 5 , the auxiliary positioning device 3 includes an insertion rod 303. A linkage rod 304 is slidably connected to the inner surface of the insertion rod 303. There are two groups of linkage rods 304. Multiple groups of auxiliary rods 302 are fixedly connected to the far ends of the two groups of linkage rods 304 away from each other. A pull rod 301 is fixedly connected to the upper end of the outer arc surface of the insertion rod 303.

[0029] A rectangular chute is provided at the upper end of the inner surface of the insertion rod 303, so that the linkage rod 304 can extend and slide in this chute. Multiple through holes are provided on the outer arc surface of the insertion rod 303, so that multiple groups of auxiliary rods 302 can pass through. The outer arc surface of the insertion rod 303 is slidably connected to the support leg 5. The upper end of the linkage rod 304 is provided as an inclined surface. The two groups of linkage rods 304 are symmetrically distributed with the midline of the insertion rod 303 as the axis of symmetry. The two groups of linkage rods 304 are elastically connected by a spring. Therefore, when the upper end of the linkage rod 304 disengages from the frustum-shaped groove at the upper end of the inner surface of the support leg 5, the spring force can push the two groups of linkage rods 304 to move away from each other, and drive the auxiliary rods 302 to extend and pierce into the soil layer to increase the overall stability of the device. The end of the auxiliary rod 302 away from the linkage rod 304 is provided as a cone. The outer surface of the pull rod 301 is slidably connected to the support leg 5.

[0030] Working principle: When this device is in use, it is necessary to rotate multiple support legs 5 so that the support legs 5 support on the ground and provide stable support for the base 1. At the same time, the pull rod 301 can be pushed by stepping on it or by hand, so that it drives the insertion rod 303 to extend outwards. At this time, the insertion rod 303 will insert into the ground through the pointed tip at its lower end, thereby enhancing the stability of this device. At the same time, during the process of the insertion rod 303 extending out, the linkage rod 304 will gradually move away from the arc surface at the upper end of the inner surface of the support leg 5. At this time, the two linkage rods 304 will be pushed in opposite directions due to the spring force, and drive the auxiliary rod 302 to extend and insert into the soil layer to enhance the fixed stability of this device.

[0031] At the same time, when this device is in use, according to the height of the operator and the position convenient for exerting force, the force - adding rod 201 can be pulled upwards to drive the rotating block 202 and the clamping block 205 to move upwards as a whole. At the same time, the multi - layer telescopic rod 203 will also extend to the specified position. At this time, the force - adding rod 201 can be rotated to drive the threaded rod 206 to rotate as a whole. At this time, the clamping block 205 will be pushed by the threaded rod 206 to approach the surveying rod 4 and form a clamp on the surveying rod 4. At the same time, because the multi - layer telescopic rod 203 is rotatably connected to the base 1 through the bearing 204, the rotation at the force - adding rod 201 will not affect the stability of the base 1.

[0032] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
