Description

Technical Field

[0001] The invention relates to the technical field of ground temperature measurement, and in particular to an integrated ground temperature automatic measuring instrument. Background Art

[0002] The automatic geothermal measuring instrument in the prior art refers to a device for surveying shallow surface temperature. Geothermal refers to the general term for soil temperature at the surface and different depths below the ground. Geothermal resources are not only one of the meteorological observation items, but also a new type of energy in industrial production and energy development industries, namely shallow geothermal energy. Its energy mainly comes from solar radiation and the gradient warming of the earth. Shallow geothermal energy can be collected and utilized through heat pump technology to heat buildings. Compared with conventional heating technology, it saves 50% to 60% energy and reduces operating costs by about 30% to 40%. Due to the wide distribution of shallow geothermal energy, large reserves, rapid regeneration, and high utilization value, it can not only meet the heating needs, but also directly reduce the amount of pollution emitted, which is beneficial to environmental protection. Therefore, when exploiting shallow geothermal energy, it is necessary to use a geothermal measuring instrument for surface survey.

[0003] After searching, it was found that a real-time ground temperature measuring device is disclosed in the invention patent with the Chinese patent publication number CN111397750A. The ground temperature measuring device in the invention patent uses infrared photography to obtain the scale line image of the mercury thermometer that changes with the ground temperature, and then transmits it to the display and the memory. The scale line part of the mercury thermometer appears on the display, which is convenient for the staff to directly read the scale value of the mercury thermometer to obtain the current ground temperature data. However, the measurement method of the ground temperature measuring device is that after artificial force is applied, the casing and the mercury thermometer structure go deep into the ground to measure the temperature. On the one hand, the mercury thermometer is isolated from the external soil layer by a protective sleeve and a casing structure, which is easy to produce errors during temperature heat transfer, resulting in inaccurate ground temperature data actually measured. On the other hand, the casing structure is a manual soil drilling structure, which requires too much labor when used, and cannot accurately obtain the ground depth data; In addition, there are already a variety of shallow geothermal testers on the market that are easy to carry and have adjustable depth. This type of device generally uses rollers under the bottom plate to drive the entire device to move, and also includes a thermometer protection tube for placing the thermometer. The thermometer protection tube penetrates into the soil layer through a drill bit and a rotating handle structure that requires pressure to be applied, to meet the measurement needs of different soil layers, avoids the phenomenon that the thermometer is easy to break and difficult to install in traditional measurement methods, and enhances practicality. However, this type of equipment also requires manual pressure to rotate, and manual data recording. Field work requires collaborative operation of multiple people, resulting in excessive labor consumption and inability to drill the soil independently and obtain temperature data at different depths of the soil layer.

[0004] Therefore, in order to solve the above-mentioned problem that manual soil drilling is time-consuming and labor-intensive and cannot accurately obtain temperature data of soil layers at different depths, an integrated ground temperature automatic measuring instrument is proposed.

[0018] The ground-drilling temperature measurement structure 3 includes a gantry 301 fixed to the front of the measuring box 1, a reduction motor 302 is fixedly installed on the top left side of the gantry 301, the internal rotation of the gantry 301 is connected to a second threaded screw 303, the external thread of the second threaded screw 303 is connected to a lifting seat 304, and the bottom of the lifting seat 304 is fixedly connected to a drilling rod 305.

[0019] A battery pack 4 is fixedly installed on the inner bottom wall of the measuring box 1, and the pay-off motor 202 and the measuring motor 201 are electrically connected to the battery pack 4. Two first pulleys 5 are rotatably connected to the inner left wall of the measuring box 1, and the output end of the measuring motor 201 is fixedly connected to the right end of one of the first pulleys 5 through a No. 1 coupling.

[0020] The battery pack 4 can supply power to the pay-off motor 202, the measuring motor 201 and other equipment, and the battery pack 4 is a storage battery structure that can be cyclically charged and discharged, providing convenience for the outdoor use of the measuring box 1. The measuring motor 201 is used to drive the No. 1 coupling, and the No. 1 coupling drives one of the first pulleys 5 to rotate.

[0021] A second pulley 6 is coaxially fixed to the outside of the second sleeve shaft 206, one of the first pulleys 5 is connected to the second pulley 6 through a No. 1 belt, the output end of the pay-off motor 202 is fixedly connected to the right end of another first pulley 5 through a No. 2 coupling, and two third pulleys 7 are coaxially fixed to the outside of the first sleeve shaft 204.

[0022] One of the first pulleys 5 drives the second pulley 6 through the No. 1 belt. Since the second pulley 6 is coaxially fixed to the outside of the second sleeve shaft 206, the second sleeve shaft 206 rotates synchronously with one of the first pulleys 5 and the second pulley 6. The unwinding motor 202 drives the other first pulley 5 by driving the No. 2 coupling. The other first pulley 5 drives one of the third pulleys 7 through the No. 2 belt.

[0024] Another third pulley 7 drives the fourth pulley 8 through the third belt. Since the fourth pulley 8 is coaxially fixed with the first threaded screw 211, the first threaded screw 211 rotates synchronously with the other third pulley 7 and the fourth pulley 8 in the same direction. That is, at this time, the first threaded screw 211 rotates synchronously with the first sleeve shaft 204 in the same direction. Since bearing seats are provided at both ends of the second sleeve shaft 206 and the first threaded screw 211, the left and right ends of the second sleeve shaft 206 and the left and right ends of the first threaded screw 211 are rotatably connected to the inner sides of the four bearing seats respectively.

[0025] A magnetic sensor 9 is fixedly installed on the left side of the first meter wheel 207 and the second meter wheel 210, and a magnet block 10 is fixedly connected to the left side of the first meter wheel 207 and the second meter wheel 210. A signal processor 11 and a counting display 12 are fixedly installed on the left side of the measuring box 1. The two magnetic sensors 9 are electrically connected to the signal processor 11 through a CMOS circuit, and the signal processor 11 is electrically connected to the counting display 12.

[0026] A magnetic sensor 9 and a magnet block 10 are provided on the left side of the first meter wheel 207 and the second meter wheel 210. After one of the magnet blocks 10 rotates to the magnetic field detection area of ​​one of the magnetic sensors 9, the magnetic field change is detected by the magnetic sensitive element of the magnetic sensor 9. The CMOS circuit connected to the magnetic sensor 9 converts the magnetic field change signal into an electrical signal, and converts the electrical signal into a corresponding pulse signal and transmits it to the signal processor 11. The signal processor 11 processes and performs logical calculations, and converts the circumference of the first meter wheel 207 and the second meter wheel 210 into the moving length of the rope 15, so as to measure the downward movement height of the drilling rod 305, and displays the descending height data on the display screen of the counting display 12 for easy reading.

[0027] The left side of the encoder 209 is rotatably connected to a photoelectric code disk, and the photoelectric code disk is provided with a photoelectric transmitter and a photoelectric receiver on the side facing the second meter wheel 210. A photoelectric converter is provided inside the encoder 209, and the photoelectric converter is electrically connected to the signal processor 11. A circuit board 13 and a control panel 14 are fixedly installed on the left side of the measuring box 1, a rope 15 is wound on the outside of the winding drum 205, and the external thread of the first threaded screw 211 is connected to a guide plate 16, and a pulley is movably installed on the inner side of the guide plate 16.

[0028] The left side of the encoder 209 is a photoelectric encoder structure, which is provided with annular open and dark engraved lines, and is also provided with a photoelectric transmitter and a receiving device. The photoelectric encoder is fixedly connected to the right side of the second meter wheel 210. When the photoelectric encoder rotates with the second meter wheel 210, the photoelectric converter inside the encoder 209 will output a pulse signal and transmit it to the signal processor 11. The signal processing circuit of the signal processor 11 calculates the rotation angle and rotation speed of the photoelectric encoder according to the number and frequency of the pulse signal, that is, measures the rotation speed and rotation angle of the first meter wheel 207 and the second meter wheel 210 when they move with the rope 15.

[0029] The internal rotation of the gantry 301 is connected with two sprockets 17, the number of the second threaded screws 303 is two, the tops of the two second threaded screws 303 are coaxially fixed to the two sprockets 17 respectively, the two sprockets 17 are connected by a chain belt transmission, and the output end of the reduction motor 302 is fixedly connected to the top of one of the sprockets 17.

[0030] The reduction motor 302 drives one of the sprockets 17, and the two sprockets 17 rotate synchronously through the chain belt. The bottoms of the two sprockets 17 are used to synchronously drive the two second threaded screws 303. The left and right sides of the lifting seat 304 are fixedly connected with slip rings. Two vertical grooves are opened on the inner side of the door frame 301. The two slip rings are connected to the external threads of the two second threaded screws 303 through the two vertical grooves. The two slip rings are driven by the two second threaded screws 303, and the two slip rings drive the lifting seat 304 to move up and down.

[0031] The outside of the meter rope 15 is frictionally fitted with the opposite sides of the first meter wheel 207 and the second meter wheel 210 through a pulley. A threading hole is provided on the inner front wall of the measuring box 1. One end of the meter rope 15 passes through the threading hole and is fixedly connected to the top of the lifting seat 304.

[0032] Specifically, one end of the meter rope 15 passes through the pulley of the guide plate 16, and then passes through the wire groove on the opposite side of the first meter wheel 207 and the second meter wheel 210, and by driving the pulley, the first meter wheel 207 and the second meter wheel 210 to rotate, one end of the meter rope 15 extends out of the threading hole on the front wall of the measuring box 1, and then is connected to the lifting ring on the top of the lifting seat 304. When the lifting seat 304 descends, the meter rope 15 is driven to move. At this time, the first meter wheel 207 and the second meter wheel 210 are used to measure the moving distance of the meter rope 15, and the depth of the lifting seat 304 entering the soil layer can be measured.

[0033] The first threaded screw 211 will rotate synchronously with the winding drum 205 in the same direction. At this time, the guide plate 16 on the first threaded screw 211 will slide left and right, so that the meter-counting rope 15 is evenly distributed on the outside of the winding drum 205, avoiding the accumulation and interlacing of the meter-counting rope 15 when winding.

[0034] Furthermore, three equidistantly distributed chambers are provided inside the drilling rod 305, and the three chambers are interconnected. A soil temperature sensor 18 is fixedly installed on the inner left wall of each chamber, and a temperature sensing end is fixedly connected to the left side of the three soil temperature sensors 18, and the three temperature sensing ends extend to the left side of the drilling rod 305.

[0035] Specifically, the three chambers are interconnected, and the temperature sensing ends of the three soil temperature sensors 18 are extended to the left side of the drilling rod 305. When the drilling rod 305 penetrates into the underground soil layer, the temperature sensing end is used to contact the soil layer, and the temperature of the soil layer is detected by the thermistor inside the temperature sensing end. Then, the soil temperature sensor 18 is connected to a cable of a certain length, and the cable passes through the chamber and is connected to the signal processor 11, and the detected temperature data is displayed on the display screen of the counting display 12 for easy reading.

[0036] When the soil boring rod 305 enters the soil layers at different depths, the three soil temperature sensors 18 simultaneously measure the soil layer temperatures at three measuring points in the vertical direction of the soil layer, thereby improving the comparability and reference of the temperature data.

[0037] according to Fig.10 The measuring box 1 is provided with a control button structure, according to the attached Fig.11 and attached Fig.12 The meter component of the measuring box 1 is externally connected to the APP wireless module, the temperature control board is electrically connected to the conductive ring 203, and the conductive ring 203 is connected to the probe line.

[0038] The specific working principle of the present invention is as follows: two sprockets 17 are driven by a reduction motor 302, and the two sprockets 17 synchronously drive the two second threaded screws 303 to rotate through the chain belt, so that the lifting seat 304 and the drilling rod 305 descend at a uniform speed into the formation, thereby achieving the effect of automatic drilling measurement. One of the first pulleys 5 is driven by the measuring motor 201, and one of the first pulleys 5 drives the second pulley 6 and drives the second sleeve shaft 206. At this time, the pay-off motor 202 drives another first pulley 5, and the other first pulley 5 drives the fourth pulley 8 through two third pulleys 7 in turn, so that the winding drum 205 rotates to perform the pay-off process, and one end of the meter rope 15 drives the first meter wheel 207 and the second meter wheel 206 by friction as the lifting seat 304 descends. The wheel 210 rotates, measures the line-releasing length and displays it on the counting display 12, so as to accurately measure the penetration depth of the soil drilling rod 305. Three soil temperature sensors 18 with equal height distribution are arranged inside the soil drilling rod 305. When the soil drilling rod 305 enters the soil layers at different depths, the soil layer temperatures at three measuring points are measured simultaneously by the three soil temperature sensors 18, so as to improve the comparability and reference value of the data. Meanwhile, when the winding drum 205 is driven in reverse to wind up the line, the first threaded screw 211 rotates synchronously with the winding drum 205 through the fourth pulley 8 in the same direction. At this time, the guide plate 16 on the first threaded screw 211 will slide left and right, so that the meter rope 15 is evenly distributed on the outside of the winding drum 205, so as to avoid the situation of stacking and interlacing when winding up the line.
