[0021] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0022] Example 1: See Figures 1 to 9 In an embodiment of the present invention, a soil temperature and humidity detector for a ground source heat pump system includes a detection box 1, a rotating cylinder 24 is rotatably installed at the outer position of the bottom of the detection box 1, a driven pulley 20 is fixedly installed at the bottom of the rotating cylinder 24, a fixed frame 10 is symmetrically fixedly installed at the bottom of the driven pulley 20, a fixed cylinder 9 is fixedly installed between the bottoms of the fixed frames 10, a telescopic square column 8 is slidably installed inside the fixed cylinder 9 through a fixed groove 28, the cross-section of the telescopic square column 8 is a rectangular structure, and cooperates with the cross-section of the fixed groove 28, a detection cylinder 7 is arranged at the bottom of the telescopic square column 8, a detection mechanism is arranged inside the detection cylinder 7, a screw-in mechanism for driving the telescopic detection cylinder 7 to move is arranged on the driven pulley 20, so that the detection cylinder 7 is continuously pressed into the soil while rotating, and a driving mechanism for driving the rotating mechanism to work is also arranged inside the detection box 1.

[0023] In one case of this embodiment, the screw-in mechanism includes a rotating shaft 13 rotatably mounted inside the rotating cylinder 24, and the outer side of the rotating shaft 13 is connected to an internal threaded hole 39 arranged inside the telescopic square column 8 through a threaded area 11. The screw-in mechanism also includes a self-rotation component.

[0024] The self-rotating assembly includes a locking cylinder 23 symmetrically fixed to the bottom of the driven pulley 20 . The locking cylinder 23 is connected to a locking column 26 via a locking portion. The locking column 26 is symmetrically fixed to both sides of the upper end of the detection cylinder 7 .

[0025] In addition, in order to ensure that the detection tube 7 does not affect its up and down movement while rotating, the locking part includes a locking groove 27 arranged inside the locking tube 23 and a locking bar 25 fixed on the locking column 26, and the locking bar 25 is slidably arranged inside the locking groove 27.

[0026] The working principle of the above-mentioned screw-in mechanism is as follows: during the rotation of the driven pulley 20, the locking cylinder 23 will be driven to rotate synchronously along the axial position of the driven pulley 20, and then, with the cooperation of the locking part, the fixed plate 22 will drive the entire detection cylinder 7 to rotate synchronously. During this process, the rotating shaft 13 also rotates, and then, with the cooperation of the threads of the threaded area 11 and the internal threaded hole 39, the telescopic square column 8 moves linearly downward along the fixed groove 28 set on the fixed cylinder 9, and finally, the detection cylinder 7 in the rotating state moves toward the inside of the soil at the same time, so as to better detect the soil temperature and humidity.

[0027] In addition, in order to effectively ensure the normal movement of the screw-in mechanism, the driving mechanism includes a driving shaft 15 rotatably installed inside the detection box 1, and the end of the driving shaft 15 is connected to the upper end of the rotating shaft 13 through a gear set a21. The driving shaft 15 is also connected to a transmission shaft 17 rotatably set on the detection box 1 through a gear set b16. A driving pulley 18 is fixedly installed at the bottom of the transmission shaft 17, and the outer side of the driving pulley 18 is connected to the driven pulley 20 through a belt 19. A detection motor 12 is also installed on the outer wall of the detection box 1, and the output end of the detection motor 12 is connected to the driving shaft 15.

[0028] The detection motor 12 drives the driving shaft 15 to rotate. On the one hand, it drives the transmission shaft 17 to rotate under the action of the gear group b16. Then, with the cooperation of the active pulley 18 and the belt 19, the driven pulley 20 rotates synchronously, finally ensuring the rotation of the detection tube 7 and the double linear precession motion.

[0029] In one case of this embodiment, the detection mechanism includes a soil storage cylinder 32 fixed inside the detection cylinder 7, and a plurality of detection grooves 43 are evenly arranged on the side walls of the soil storage cylinder 32. A detection shaft 29 is rotatably installed in the upper and lower areas between the outer wall of the soil storage cylinder 32 and the inner wall of the detection cylinder 7. A plurality of detection needles 30 that cooperate with the detection grooves 43 are installed on the detection shaft 29, and a temperature and humidity sensor 31 is installed on the detection needle 30. The detection mechanism also includes a control component for changing the angle of the detection shaft 29.

[0030] Among them, the control component includes a control seat 35 symmetrically fixed on the outer wall of the upper end of the detection tube 7, a control shaft 37 is rotatably installed between the control seats 35, a control handle 38 is fixedly installed at one end of the control shaft 37, and a control worm gear 36 is also provided on the control shaft 37, and the control worm gear 36 is meshed with the control worm wheel 34 fixed on the top of the detection shaft 29.

[0031] After the detection tube 7 collects the soil, the control handle 38 is rotated so that the control shaft 37 drives the control worm gear 36 to rotate, and then engages with the control worm gear 34 to drive the detection shaft 29 to rotate. Then, the detection needle 30 drives the temperature and humidity sensor 31 to pass through the detection groove 43 and enter the soil inside the soil storage tube 32 to detect the soil temperature and humidity at different depths, thereby obtaining the soil temperature and humidity at different depths where the ground source heat pump system is located. The whole operation process is quick and convenient, and is worthy of popularization.

[0032] In order to quickly read the temperature and humidity parameters obtained by the temperature and humidity sensor 31, in this embodiment, an output interface line 33 is provided inside the control shaft 37, one end of the output interface line 33 is electrically connected to the temperature and humidity sensor 31, and the other end extends to the outer position of the detection tube 7 and is detachably electrically connected to the input interface line 4, and the input interface line 4 is electrically connected to the reading display screen 3 fixed on the outer wall of the detection box 1. After the temperature and humidity sensor 31 is controlled to enter the soil at the corresponding depth, the output interface line 33 and the input interface line 4 are plugged into each other, and then the temperature and humidity of the corresponding depth are obtained under the action of the reading display screen 3.

[0033] Meanwhile, a battery pack 14 is installed inside the detection box 1, and the battery pack 14 is used to supply power to the electrical equipment involved in the entire detection instrument. A handrail 2 is symmetrically installed on the outer wall of the detection box 1 to facilitate the staff to perform detection operations on the entire detection instrument.

[0034] Embodiment 2: In another embodiment of the present invention, this embodiment differs from the above-mentioned embodiment in that it also includes a soil discharge mechanism.

[0035] The soil discharge mechanism includes an air guide ring 41 fixed at the middle position of the upper end of the detection tube 7, the air guide ring 41 is connected with the air guide hole 40 arranged at the upper end of the detection tube 7, a fixed plate 22 is fixedly installed at the bottom of the telescopic square column 8, an air guide tube 42 is installed on the fixed plate 22, the upper end of the air guide ring 41 is rotatably arranged inside the air guide tube 42, the outer wall of the air guide tube 42 is connected and installed with an air guide pipe 6, and the air guide pipe 6 is connected and coordinated with the compressed air pump 5 fixed on the detection box 1.

[0036] After the detection is completed, the compressed air pump 5 is started to continuously input high-pressure gas into the air cylinder 42 through the air pipe 6. Then, the air pipe 6 and the air hole 40 cooperate with each other to introduce the high-pressure gas into the soil storage cylinder 32. Then, the cylindrical soil sampled and collected before is pressed downward under the action of the high-pressure gas, which accelerates the separation of the soil from the soil storage cylinder 32.

[0037] To summarize, first, the staff inserts the detection tube 7 into the corresponding soil through the handrail frame 2, and then starts the detection motor 12, and then makes the detection mechanism work under the action of the driving mechanism, and finally obtains the temperature and humidity of the soil at different depths in the corresponding area. After the detection is completed, the detection motor 12 is started in reverse, and then the compressed air pump 5 is started, and then under the action of the soil discharge mechanism, the soil collected and sampled before is discharged into the original collection area, thereby avoiding the need for artificial filling and further ensuring the quality of the detector.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
