Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] like Figure 1 , Figure 4As shown, the soil temperature measuring device for environmental geological survey in this embodiment includes an outer sleeve 1, a central axis 2, a temperature measuring probe 3 and a crank connecting rod structure.

The central axis 2 is inserted into the outer sleeve 1 and is coaxially arranged with the outer sleeve 1. The central axis 2 is rotatably connected to the outer sleeve 1. The temperature measuring probe 3 is slidably inserted into the through hole, and can selectively protrude from the outer wall of the outer sleeve 1 or shrink inside the outer wall of the outer sleeve 1. The crank connecting rod 5 structure connects the central axis 2 and the temperature measuring probe 3.

[0027] In this embodiment, a bearing seat 7 is sleeved on the central shaft 2, a bearing is installed between the bearing seat 7 and the central shaft 2, a connecting rod 8 is fixedly connected to the outer side of the bearing seat 7, and one end of the connecting rod 8 away from the bearing seat 7 is fixedly connected to the inner wall of the outer sleeve 1, so that the central shaft 2 is rotatably connected to the outer sleeve 1. Preferably, a plurality of bearing seats 7 are sleeved on the central shaft 2 at equal intervals to make the structure more stable.

[0028] In this embodiment, if Figure 4 , Figure 5 As shown, the crank-connecting rod structure includes a turntable 4, a connecting rod 5 and a sliding mounting seat 6.

The two ends of the connecting rod 5 are rotatably connected to the turntable 4 and the sliding mounting seat 6 respectively, and the end of the temperature measuring probe 3 is connected to the sliding mounting seat 6. By rotating the central shaft 2, the central shaft 2 drives the turntable 4 to rotate, and the rotation of the turntable 4 drives the connecting rod 5 to move. Since the sliding mounting seat 6 is connected to the temperature measuring probe 3, the temperature measuring probe 3 is slidably connected to the through hole, so that the sliding mounting seat 6 and the temperature measuring probe 3 can only perform linear motion along the axial direction of the through hole, and finally the temperature measuring probe 3 is extended or retracted into the outer wall of the outer sleeve 1.

[0029] In this embodiment, a plurality of rotating disks 4 are sleeved axially on the central axis 2, two connecting rods 5 are relatively connected to each rotating disk 4, and a sliding mounting seat 6 is connected to the end of the connecting rod 5 away from the rotating disk 4, and a temperature measuring probe 3 is installed on the sliding mounting seat 6, and a through hole corresponding to the temperature measuring probe 3 is opened on the outer sleeve 1. Therefore, not only the temperature of soil at different depths can be measured, but also the temperature of soil at the same soil depth and on both sides of the outer sleeve 1 can be measured, thereby improving the measurement accuracy.

[0030] In this embodiment, a guide tube 11 is fixedly arranged in the through hole, the outer side of the guide tube 11 is flush with the outer wall of the outer sleeve 1, the inner side of the guide tube 11 is flush with the inner side of the outer sleeve 1 or protrudes from the inner wall of the guide tube 11, and the inner wall of the guide tube 11 is provided with a heat insulation layer, and the temperature measuring probe 3 is penetrated in the heat insulation layer.

[0031] In this embodiment, if Figure 2 , Figure 3 As shown, a connection seat 9 is fixed to the upper end of the central shaft 2, and a card slot 10 is provided on the top surface of the connection seat 9.

The crank is plug-in connected to the connection seat 9 through the card block. Preferably, an indicator line is provided on the top edge of the connection seat 9 and the top surface of the uppermost connecting rod 8, so that it is convenient to judge the position of the temperature measurement probe 3 according to the position of the indicator line and rotate the central shaft 2.

[0032] The soil temperature measuring device for environmental geological survey in this embodiment further includes a shaft fixing plug 12. Figure 3 , Figure 6 As shown, the shaft fixing plug 12 is detachably sleeved on the connecting seat 9, and the shaft fixing plug 12 is clamped with the connecting seat 9 and the outer sleeve 1, thereby limiting the rotation of the central shaft 2 and ensuring the stability of the soil temperature measurement. Specifically, a protrusion is fixed on the outside of the connecting seat 9, preferably, the two protrusions are symmetrically arranged, and two first grooves are symmetrically opened on the top of the inner side wall of the outer sleeve 1, and the shaft fixing plug 12 includes a sleeve 1201 and a clamping plate 1202. The lower end of the sleeve 1201 is open, and the side wall of the lower end is opened with a second groove adapted to the protrusion.

[0033] A first connecting column 1203 is fixed to the top surface of the ferrule 1201. The soil temperature measuring device for environmental geological survey in this embodiment also includes a rain cover 13. A second connecting column 15 is fixed to the inner side of the rain cover 13. The second connecting column 15 is threadedly connected to the first connecting column 1203. A handle 14 is provided on the outer side of the upper end of the outer sleeve 1.

[0034] The working principle of the soil temperature measuring device for environmental geological survey in this embodiment is:

[0035] By opening a through hole on the side wall of the outer sleeve 1, a central axis 2 is rotatably set in the outer sleeve 1, and the central axis 2 and the temperature measuring probe 3 are connected by a crank connection structure. By rotating the central axis 2, the end of the temperature measuring probe 3 away from the central axis 2 can extend out of the outer wall of the outer sleeve 1 or retract into the inner side of the outer wall of the outer sleeve 1. The end of the temperature measuring probe 3 away from the central axis 2 extends out of the outer wall of the outer sleeve 1 and can directly contact the soil outside the outer sleeve 1 for measurement, so that the measurement data is more accurate.
