[0019] The inner top surface of the lifting rod 2 is installed with a fixing frame 3 and a mounting frame 4 from right to left in sequence. A take-up roller 301 is installed inside the fixing frame 3. One end of the take-up roller 301 passes through the outer wall of the fixing frame 3 and is installed with a first gear 302. The outer wall of the first gear 302 is meshed with a second gear 305. A pulley 401 is installed inside the mounting frame 4. A rope 5 is wrapped around the outer wall of the take-up roller 301. One end of the rope 5 passes around the pulley 401 and is detachably connected to the freezer body 601 through a pull ring.

[0020] In this embodiment: when in use, the height of the lifting rod 2 can be adjusted by rotating the screw 101, so that the lifting rod 2 can be adjusted to be higher than the highest frozen soil depth. Then, the control button 103 is pressed to rotate the second gear 305 to drive the first gear 302 and the take-up roller 301 to rotate forward, so that the take-up roller 301 will wind up the rope 5 between the pull ring and the pulley 401, so that the freezer body 601 can be pulled out from the base 6, which is convenient for the observer to observe the icicle scale in the hose of the freezer body 601. After the observation is completed, the rope 5 is released by rotating the take-up roller 301 in the opposite direction, and the freezer body 601 is moved to its original position, thereby realizing automatic pulling up and lowering of the freezer body 601, which is convenient for observing data and increasing the accuracy of the data.

[0021] As a technical optimization solution of the present invention, a support plate 303 is installed on the front end face of the fixed frame 3, and a motor 304 is installed on the front end face of the support plate 303. The output end of the motor 304 passes through the support plate 303 and is fixedly connected to the second gear 305.

[0022] In this embodiment, by starting the motor 304 , the second gear 305 can be driven to rotate, thereby causing the second gear 305 to drive the first gear 302 to rotate.

[0023] As a technical optimization solution of the present invention, two control buttons 103 electrically connected to the motor 304 are installed on the outer side wall of the upright pole 1 .

[0024] In this embodiment, two control buttons 103 are provided to respectively control the forward rotation and reverse rotation of the motor 304 , thereby controlling the forward rotation and reverse rotation of the take-up roller 301 .

[0025] As a technical optimization solution of the present invention, anti-slip grooves are provided on one side of the fixing plate 102 close to the lifting rod 2 .

[0026] In this embodiment, by providing the anti-slip grooves, the friction between the fixing plate 102 and the lifting rod 2 can be increased, thereby increasing the stability of the lifting rod 2.

[0027] As a technical optimization solution of the present invention, the outer side walls of the lifting rod 2 and the vertical rod 1 are both provided with scales.

[0028] In this embodiment, scales are provided on the outer side walls of the lifting rod 2 and the upright pole 1 to facilitate adjustment of the height of the lifting rod 2 .

[0029] As a technical optimization solution of the present invention, the outer side wall of the hose of the freezer body 601 is translucent and provided with scale lines.

[0030] In this embodiment, scale lines are provided on the rubber hose of the soil freezer body 601 to facilitate observation of the frozen soil depth.

[0031] Working principle: First, when using the device, connect the device to an external power source, then loosen the screw 101 to make the fixing plate 102 away from the lifting rod 2, then move the lifting rod 2 and adjust the lifting rod 2 to a position higher than the highest frozen soil depth through the scale line on its outside, and tighten the screw 101 so that the fixing plate 102 fixes the position of the lifting rod 2, then press the control button 103 that controls the forward rotation of the motor 304, so that the second gear 305 rotates to drive the first gear 302 and the take-up roller 301 to rotate forward. By rotating in the opposite direction, the rope 5 can be pulled along the pulley 401, so that the take-up roller 301 will wind and retract the rope 5 between the pull ring and the pulley 401, so that the freezer body 601 can be pulled out from the base 6, so as to achieve the purpose of not falling off the rope. The observer reads the frozen soil depth by observing the icicle scale in the hose of the freezer body 601. After the observation is completed, press another control button 103 that controls the reverse rotation of the motor 304, so that the take-up roller 301 rotates in the opposite direction, releases the rope 5, and moves the freezer body 601 to its original position.

[0032] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
