As shown in fig. 1, the holding portion 12 is provided with a pair of holding grooves symmetrically arranged around the inner cylinder 1 so as to hold the inner cylinder 1 for operation.
As shown in fig. 1, the sliding portion 13 is provided with a slide groove 131 (see fig. 2) for fitting connection with the outer cylinder 2. The sliding grooves 131 are symmetrically provided with two, and each sliding groove 131 is provided with a first vertical sliding groove 1311, a second horizontal sliding groove 1312 and a third vertical sliding groove 1313. The bottom of the third vertical sliding groove 1313 penetrates through the inner cylinder 1, so that the outer cylinder 2 can slide out of the inner cylinder 1.
As shown in fig. 1, the drill head 14 is conical, a through hole 141 for passing a temperature measuring probe is provided in the middle, and a plurality of drill teeth 142 are uniformly provided along the cone in the outer portion. One of the drill teeth 142 is hinged to a tip 143. The conical tip 143 ensures the drilling capability of the drill head 14 of the inner barrel 1. And meanwhile, the temperature measuring probe is hinged, so that the conical tip 143 can be pushed open when the temperature measuring probe extends into the temperature measuring probe, and the normal measurement of the temperature measuring probe is not influenced.
As shown in fig. 4, the outer cylinder 2 includes a slide block 21 and a slide ring 22, and one end of the slide block 21 is attached to the inner wall surface of the cylinder body, and the other end is slidably connected to a slide groove 131 provided in the inner cylinder 1. For the purpose of fixing, the slip ring 22 is provided with a plurality of fixing teeth 23 at its end facing the ground. Meanwhile, the slip ring 22 is provided with a fixing hole through which the temperature measuring probe passes.
As shown in fig. 3, in order to control and define the slide position of the slide block 21. The wall of the inner cylinder 1 is provided with two pull rods 15, the two pull rods 15 are respectively adjacent to the first vertical sliding groove 1311 and parallel to the first vertical sliding groove 1311, the top end of each pull rod 15 is flush with the top end of the inner cylinder 1, the top end of each pull rod 15 is provided with a pull ring 151 (see fig. 1), and the bottom end of each pull rod 15 is abutted to one side of the second horizontal sliding groove 1312 far away from the top end of the inner cylinder 1. When the pull rod 15 falls, the slide block 21 is limited to move in the direction of the first vertical sliding groove 1311. When the pull rod 15 is pulled out, the slide block 21 can slide out along the first vertical slide groove 1311, the second horizontal slide groove 1312 and the third vertical slide groove 1313 in sequence.
As shown in fig. 3, the wall of the inner cylinder 1 is further provided with a limiting structure for limiting the pull rod 15 to be separated from the inner cylinder 1, a limiting cavity 16 is arranged at the position of the wall of the inner cylinder 1 close to the second transverse sliding groove 1312, and the limiting structure is installed in the limiting cavity 16. The limiting structure can be a spring 17, a limiting baffle 18 is arranged at the position, close to the second transverse sliding groove 1312, of the pull rod 15, one end of the spring 17 is abutted to one end, close to the top of the inner barrel 1, of the limiting cavity, and the other end of the spring 17 is abutted to the limiting baffle 18. The pull rod 15 is pulled out, and the limit stop piece 18 compresses the spring 17, so that the second transverse sliding groove 1312 is unobstructed. When released, the compressed spring 17 automatically recovers, returning the pull rod 15 to its original position.
The specific implementation process comprises the following steps:
when the first drilling measurement is carried out, the shallow geothermal measurement drill bit is pressed into the shallow earth surface through an external pressure device. At this time, the slip ring 22 is erected on the surface soil layer, and the fixed teeth 23 are inserted into the surrounding soil layer to fix the shallow geothermal measurement drill bit. At this time, a temperature measuring probe can be used to perform the first measurement. At this moment, the pull rod 15 can be pulled out through the pull ring 151 to drive the inner cylinder 1 to rotate, the inner cylinder 1 is slowly pulled out, and the outer cylinder 2 is continuously left at the original hole so as to be positioned quickly. The inner cylinder 1 can be used for drilling and measuring in other places. When the two subsequent measurements are completed, the inner cylinder 1 and the outer cylinder 2 are completely taken out, and the temperature measuring probe is inserted into the sliding ring 22 to prevent loss.
Example 2:
the difference from the embodiment 1 is that: as shown in fig. 5, the outer cylinder 2 further includes a cylindrical body 24, and the cylindrical body 24 is disposed between the slide block 21 and the slide ring 22. The shallow geothermal measurement drill bit is divided into the outer cylinder 2 and the inner cylinder 1 which are independent, when the outer cylinder 2 is separated from the inner cylinder 1, the cylinder 24 can support the hole wall to prevent the soil layer on the inner wall of the hole from falling off, so that the inner cylinder 1 can be quickly inserted and the second measurement can be carried out.
