[0002] Remote sensing technology is a detection technology that emerged in the 1960s. It is a comprehensive technology that uses various sensing instruments to collect, process and finally image the electromagnetic wave information radiated and reflected by distant targets based on the theory of electromagnetic waves, thereby detecting and identifying various ground scenes. Through remote sensing technology, domestic high-resolution remote sensing images such as GF-1, GF-2 and Ziyuan-3 can be queried.

[0003] At present, in the prior art, when measuring the water level of a borehole, a well, a water level pipe and a vertical shore, a detection rod is inserted into the hole and connected to a water level observation and measuring instrument through a scale rope with a scale to detect the water level.

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

[0042] See also Figure 1-11 The present invention provides a technical solution: a groundwater level observation device for hydrogeological exploration based on remote sensing technology, embodiment 1

[0043] It includes a detection rod 1 and a measuring rope 11 with a scale arranged on the detection rod 1. In the present application, the detection rod 1 moves down along the detection hole under its own gravity, thereby saving manpower and ensuring rapid detection of the water level in the detection hole. The detection rod 1 is provided with a water level sensor 12 for detecting the water level. One end of the measuring rope 11 is connected to a measuring frame 13. The measuring frame 13 is provided with a buzzer. The buzzer serves to remind the staff, that is, when the water level sensor 12 detects that it is located on the water surface, it sends a signal to the controller, and the controller makes the buzzer remember an early warning prompt. The detection rod 1 includes a connecting rod 2. One end of the connecting rod 2 is provided with a supporting shell 21, and the inside of the supporting shell 21 is provided with an adjusting member 22 for adjusting the position of the connecting rod 2 relative to the supporting shell 21;

[0044] The adjusting member 22 includes a driving motor 221 disposed inside the supporting shell 21, a driving screw 222 is fixedly connected to the output end of the driving motor 221, and a threaded hole is provided at a position of the connecting rod 2 corresponding to the driving screw 222;

[0047] The rotating mechanism 4 includes a fixed sleeve 41 fixedly connected to the inside of the supporting shell 21, and a first driving gear 42 is fixedly sleeved on the outside of the fixed sleeve 41, and a second driving gear 43 is transmission-connected to the outside of the first driving gear 42, and a rotating motor 44 for driving the second driving gear 43 is fixedly installed inside the rotating shell 3;

[0048] The ends of the two rotating shells 3 that are away from each other are each provided with an expansion fixing mechanism 5 for fixing the connecting rod 2 relative to the detection hole;

[0049] The expansion fixing mechanism 5 includes an expansion shell 51 fixedly connected to the rotating shell 3, a servo motor 52 is fixedly installed inside the expansion shell 51, and a first guide gear 53 is fixedly connected to the output end of the servo motor 52, a second guide gear 54 is meshedly connected to the outer side of the first guide gear 53, and the inner circle of the second guide gear 54 is rotatably connected to the rotating shell 3 through a support shaft, a plurality of arc grooves are equidistantly provided on the second guide gear 54, and a plurality of arc grooves are provided at each of the plurality of arc grooves, and an expansion plate 56 is connected to the connection end of the limiting guide mechanism 55, the outer side of the expansion plate 56 is arranged in an arc shape, and when not in use, it is located at the moving port, and is designed at the same edge as the outer side of the connecting rod 2, and a plurality of vertical slots are equidistantly provided on the outer side of the expansion plate 56, so that the expansion plate 56 can be stably fitted with the inner wall of the aperture, and in the present application, a cutting knife is provided at the bottom of the expansion plate 56, so that when the expansion plate 56 moves downward, when encountering obstacles such as roots of trees in the aperture, it can play a role in cutting the roots, thereby ensuring the stable movement of the connecting rod 2;

[0050] The positions of the rotating shell 3 corresponding to the plurality of expansion plates 56 are all provided with moving openings.

[0051] The limiting guide mechanism 55 comprises a guide rod 551 slidingly passing through the arc groove, the position of the rotating shell 3 corresponding to the guide rod 551 is provided with a guide groove 31 for limiting the guide rod 551, and the position of the guide rod 551 corresponding to the guide groove 31 is provided with a guide block 552;

[0052] One end of the guide rod 551 away from the guide block 552 is fixedly connected to a positioning rod, and the positioning rod is fixedly connected to the expansion plate 56;

[0053] Therefore, when the pressure value received by the pressure sensor 75 in the detection mechanism 7 is greater than its set value, and the water level sensor 12 has not reached the set value, and at the same time, in cooperation with the infrared sensor, it is detected that there is soil or stones at the bottom that block the borehole aperture, then at this time, the servo motor 52 runs, and then the first guide gear 53 drives the second guide gear 54 to rotate, and when the second guide gear 54 rotates, the arc groove on it rotates synchronously, thereby providing a driving force for the multiple guide rods 551 thereon, and because the guide rod 551 is limited by the guide groove 31, the guide rod 551 drives the expansion plate 56 to move outward along the moving mouth through the positioning rod, until the multiple expansion plates 56 stably abut against the inner wall of the aperture, so that the connecting rod 2 is fixed relative to the inside of the aperture as a whole;

[0054] At this time, the driving motor 221 is running, further causing the driving screw 222 to rotate and providing driving force for the connecting rod 2. Because the connecting rod 2 is further moved vertically downward along the rotating hole under the action of the two limit rods 223, and when the connecting rod 2 moves vertically downward, the rotating motor 44 is running, further causing the second driving gear 43 to drive the first driving gear 42 to rotate, so that the connecting rod 2 rotates relative to the rotating shell 3. When the connecting rod 2 rotates, the first conical block 23 at the bottom thereof is synchronously driven to rotate, further realizing the function of drilling holes in the soil and stones. When the drilling is completed, the driving motor 221 runs in the reverse direction, thereby moving the connecting rod 2 to a position close to the top supporting shell 21.

[0055] At the same time, when the detection rod 1 moves upward and blockage occurs, the expansion fixing mechanism 5 located at the bottom of the connecting rod 2 is opened, so that the expansion shell 51 at the bottom is relatively fixed in the aperture. At this time, the connecting rod 2 is relatively fixed, and the driving motor 221 runs, thereby causing the second conical block 24 to move upward and rotate relative to the connecting rod 2, further achieving the effect of clearing the drilled hole during the upward movement.

[0056] A first conical block 23 is fixedly connected to the top of the expansion fixing mechanism 5 located above the connecting rod 2, and the measuring rope 11 is installed on the first conical block 23;

[0057] A floating mechanism 6 is provided on the expansion and fixing mechanism 5 below the connecting rod 2 , and a second conical block 24 is provided at the bottom of the floating mechanism 6 , and a detection mechanism 7 is provided at the bottom of the second conical block 24 .

[0058] The floating mechanism 6 includes a floating shell 61 disposed at the bottom of the expansion shell 51 below the connecting rod 2, a lifting mechanism 62 is disposed inside the floating shell 61, and a plurality of baffles 63 are connected to the outside of the lifting mechanism 62, and a floating plate 64 is disposed inside the baffle 63;

[0059] The lifting mechanism 62 includes a rotating screw 621 rotatably connected to one end of the top of the floating shell 61, a first rotating gear 622 is fixedly sleeved on the outer side of the rotating screw 621, and a second rotating gear 623 is meshedly connected on the outer side of the first rotating gear 622, and a rotating motor 624 for driving the second rotating gear 623 is fixedly installed inside the floating shell 61;

[0060] A connecting frame 625 is rotatably sleeved on the outer side of the rotating screw rod 621, and a plurality of baffles 63 are fixedly connected to the outer side of the connecting frame 625;

[0061] The floating shell 61 is provided with a positioning opening for moving the plurality of floating plates 64, and the inner side of the plurality of floating plates 64 is provided with a telescopic connection mechanism 65;

[0062] The telescopic connection mechanism 65 includes a telescopic rod 651 fixed to one side of the floating plate 64, a telescopic sleeve 652 is slidably sleeved on the outer side of the telescopic rod 651, the telescopic sleeve 652 is fixedly mounted on the support block 653, and an electromagnet 654 is provided at a position of the support block 653 corresponding to the telescopic sleeve 652, and the telescopic rod 651 is made of metal material, and the telescopic rod 651 is made of iron;

[0063] A connecting spring 655 for connecting the telescopic rod 651 is provided inside the telescopic sleeve 652 .

[0064] When the pressure sensor 75 reaches its set value through the extrusion of the contact plate 77, and at the same time, under the action of the infrared sensor and the water level sensor 12, the second conical block 24 moves relatively to the water surface, and then the multiple expansion plates 56 are opened to achieve the effect of decelerating the detection rod 1 when it descends, further reducing the impact force between the detection rod 1 and the water surface, and at the same time, the buzzer alarm is sounded to achieve the effect of prompting the position of the water level. At the same time, the detection rod 1 continues to move downward, and the rotating motor 624 is running, further making the rotating screw 621 relative to the floating shell 61. When the screw rod 621 rotates, it provides driving force to the connecting frame 625, so that the connecting frame 625 drives multiple baffles 63 to deviate from the positioning port position. At this time, due to the reverse elastic force of the connecting spring 655, the floating plate 64 is further moved to the outside of the floating shell 61, so as to support the connecting rod 2, thereby ensuring that the water level sensor 12 is relatively located on the water surface, thereby reducing its measurement error. When the detection is completed and the rocker 134 is shaken, the electromagnet 654 is energized, so as to recover the floating plate 64.

[0065] The detection mechanism 7 includes a first receiving hole 71, a second receiving hole 72 and a third receiving hole 73 arranged at the bottom of the second conical block 24, and an infrared distance measuring sensor 74 is installed inside the first receiving hole 71;

[0066] A pressure sensor 75 is installed inside the second receiving hole 72, and the pressure sensor 75 is fixedly connected to an elastic sleeve 76, and one end of the elastic sleeve 76 is fixedly connected to a contact plate 77, and the contact plate 77 is located at the second receiving hole 72;

[0067] The water level sensor 12 is installed at the third receiving hole 73 .

[0068] The measuring frame 13 includes a winding roller 131, one end of the measuring rope 11 is fixedly connected to the winding roller 131, and the measuring rope 11 is wound around the winding roller 131;

[0069] A transfer rod 132 is fixedly passed through the center of the winding roller 131, and support plates 133 are rotatably sleeved on both ends of the transfer rod 132. A rocker 134 is installed at one end of the transfer rod 132 located outside a support plate 133. That is, the measuring position of the measuring rope 11 can be adjusted by manually shaking the rocker 134 and with the cooperation of the buzzer.

[0070] Embodiment 2

[0071] The difference from the first embodiment is that a protective shell 8 is provided on the support plate 133 located on one side of the rocker 134, a protective motor 81 is installed inside the protective shell 8, and a positioning gear 82 is fixedly connected to the output end of the protective motor 81, and an outer gear ring 83 is meshingly connected to the outer side of the positioning gear 82, and the outer gear ring 83 is rotatably connected to the support plate 133 through a bearing seat, a plurality of connecting holes are equidistantly provided on the inner side of the outer gear ring 83, and an electric push rod 84 is fixedly installed inside the connecting hole, and a clamping plate 85 is fixedly connected to the output end of the electric push rod 84.

[0072] Therefore, when the infrared sensor detects that it is close to the water surface, the buzzer will sound an alarm and multiple electric push rods 84 will operate, further making the winding roller 131 relatively fixed. At the same time, under the action of the pressure sensor 75, when it is detected that the pressure value is large, the controller controls the protection motor 81 to rotate, further making the winding roller 131 rotate in the opposite direction until the measuring line is in a tensioned state. At this time, quick readings can be made manually.

[0073] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
