Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. 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.

[0030] Embodiment 1

[0031] The present invention provides a technical solution: a groundwater level monitoring device for geological exploration, comprising a support ring 1 supported and fixed by an external frame and a floating plate 2 floating on the liquid surface of a water area to be surveyed, wherein the support ring 1 is supported and fixed by an external frame, and the external frame can be a support frame erected on the shore of the water area, and the frame erection method is processed according to the actual landform adaptability.

[0032] The floating plate 2 floats on the liquid surface of the water area to be detected, so that the change of the water level in the water area can be sensed through the ups and downs of the floating plate 2. A connecting column 3 is fixedly connected to the arc profile of the support ring 1, and a limit plug rod 4 is fixedly connected to the lower surface of the connecting column 3. The surface of the limit plug rod 4 penetrates the floating plate 2 and is limitedly slidably connected to the floating plate 2. The limit plug rod 4 is supported and connected by the connecting column 3, and the limit plug rod 4 penetrates the floating plate 2, so that the movement trajectory of the floating plate 2 is limited and can only be lifted and lowered axially. The inner wall of the support ring 1 is connected to a rotating column 5 for fixed-axis rotation, so that the support ring 1 can support the rotating column 5 when it rotates;

[0033] A connecting frame 6 is fixedly sleeved on the arc-shaped contour near the top of the rotating column 5, and two side support plates 7 are fixedly connected to the surface of the connecting frame 6. Through holes are opened on the surfaces of the two side support plates 7, and a horizontal rotating rod 8 is rotatably connected to the fixed axis in the hole. A gear 9 is fixedly sleeved on the arc-shaped contour of the horizontal rotating rod 8, and a lifting rack 10 is meshed with the teeth on the gear 9. The bottom of the lifting rack 10 is movably connected to the upper surface of the floating plate 2, and the bottom of the lifting rack 10 is in contact with the upper surface of the floating plate 2, so that the weight of the lifting rack 10 is pressed on the floating plate 2, and the floating plate 2 will be close to the liquid surface. When the water level rises, the floating plate 2 will float synchronously, and when the water level drops, the floating plate 2 will drop synchronously; a transverse plate 11 is fixedly connected to the surface of the side support plate 7, and the transverse plate 11 is penetrated by the lifting rack 10 and is connected to the lifting rack 10. The lowering rack 10 is connected with upper and lower limit sliding, and a water level monitoring surveillance camera 12 for monitoring water level changes is fixedly connected to the arc-shaped contours near the two ends of the horizontal rotating rod 8, and the rising float 2 will drive the synchronous upward movement of the lifting rack 10. Since the lifting rack 10 passes through the horizontal plate 11, its movement trajectory is also limited, and it can only be lifted axially. The upward movement of the lifting rack 10 and the gear 9 meshing with the teeth on the lifting rack 10 will drive the horizontal rotating rod 8 to rotate on the side support plate 7, and the water level monitoring surveillance camera 12 fixed on the end of the horizontal rotating rod 8 will rotate synchronously with the horizontal rotating rod 8. When the water level changes, the water level monitoring surveillance camera 12 will realize dynamic detection of the water level through continuous rotation, and the detection range is more comprehensive.

[0034] The water level monitoring camera 12 can transmit data with a remote image processing and recognition device. The water level image is photographed by the water level monitoring camera 12, and the image information is transmitted to the remote image processing and recognition device through a wireless transmission device. The relevant image processing and recognition device converts the image signal into a digital signal and processes it using a computer. The relevant technology is relatively mature and well known to those skilled in the art, so it will not be publicly described here.

[0035] Embodiment 2

[0036] Basically the same as the first embodiment, further: an adjusting device is provided on the floating plate 2, and through the setting of the adjusting device, the water level monitoring surveillance camera 12 can further adjust its position in the horizontal direction when the water level changes, so as to obtain more comprehensive monitoring data.

[0037] The adjusting device includes a vertical rotating rod 13, a rectangular sliding rod 14 is coaxially fixed to the top of the vertical rotating rod 13, a rectangular mounting hole 15 for installing the rectangular sliding rod 14 is provided on the top of the rotating column 5, a movable through hole 16 for the vertical rotating rod 13 to pass through is provided at the center of the circle on the upper surface of the floating plate 2, a guide slider 17 is fixedly connected to the inner wall of the movable through hole 16, and an outer spiral groove 18 cooperating with the guide slider 17 is provided on the arc profile of the vertical rotating rod 13.

[0038] refer to Figure 1 , Figure 2 and Figure 3 As mentioned above, the floating plate 2 can only be raised and lowered axially due to the limitation of the positioning rod 4. When the water level rises, the floating plate 2 rises synchronously, and the guide slider 17 on the inner wall of the movable through hole 16 will move up along the inner wall of the outer spiral groove 18. Under the guidance of the spiral track on the outer spiral groove 18, the vertical rotating rod 13 will lead the rectangular sliding rod 14, and the rectangular sliding rod 14 will lead the rotating column 5 to rotate in the support ring 1. From then on, the connecting frame 6, side support plate 7, horizontal rotating rod 8, gear 9, lifting rack 10, cross plate 11 and water level monitoring surveillance camera 12 on the rotating column 5 will rotate with the vertical center line of the rotating column 5 as the rotation center.

[0039] In conjunction with the previous rotation of the water level monitoring surveillance camera 12 along with the horizontal rotating rod 8, the rotation range of the water level monitoring surveillance camera 12 is further enriched, and the monitoring range of the water level monitoring surveillance camera 12 for water level changes in the water area is further improved.

[0040] Embodiment 3

[0041] Basically the same as the second embodiment, further: a display device for visualizing the water level change is provided on the inner wall of the outer spiral groove 18. Through the setting of the display device, the water level change can be visualized and digitized, so that people can quickly obtain the water level change situation on site.

[0042] The display device includes a rubber sealing tube 19 spirally wound on the inner wall of the outer spiral groove 18, and the inner wall of the rubber sealing tube 19 is wrapped with a pressure-sensitive switch module 20, and the pressure-sensitive switch module 20 is composed of a plurality of pressure-sensitive switch units 21 arranged linearly;

[0043] refer to Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 7 .

[0044] As the floating plate 2 moves up and down, the guide slider 17 will contact and squeeze the rubber sealing tube 19 at different positions on the inner wall of the outer spiral groove 18, so that the pressure-sensitive switch module 20 wrapped in the rubber sealing tube 19 is also squeezed synchronously. Since the contact between the guide slider 17 and the rubber sealing tube 19 is continuous, the squeezing of the pressure-sensitive switch module 20 is also continuous and linear. Finally, for the multiple pressure-sensitive switch units 21 that constitute the pressure-sensitive switch module 20, the multiple pressure-sensitive switch units 21 are also squeezed one by one.

[0045] Furthermore, the display device also includes a support vertical plate 22 fixed on the upper surface of the connection frame 6, and a plurality of LED light strips 23 are fixedly connected to the surface of the support vertical plate 22. The plurality of LED light strips 23 correspond one-to-one to the plurality of pressure-sensitive switch units 21 and are powered by a rechargeable battery.

[0046] refer to Figure 4 , referring to the above, the pressure-sensitive switch units 21 correspond to the LED light strips 23 one by one and are electrically connected by the rechargeable battery. When the multiple pressure-sensitive switch units 21 in the above content are squeezed one by one, the LED light strips 23 electrically connected to the corresponding pressure-sensitive switch units 21 will be powered on and light up. As mentioned earlier, the multiple pressure-sensitive switch units 21 are also squeezed one by one, that is, the multiple LED light strips 23 distributed on the supporting vertical plate 22 are also lit up one by one, that is, the multiple LED light strips 23 are linearly lit up one by one from bottom to top or from top to bottom on the supporting vertical plate 22, and the lighting speed is affected by the speed of water level rise;

[0047] At this point, on site, people can roughly judge the height of the water level by observing the position of the light on the support vertical plate 22.

[0048] Furthermore, a scale mark 24 is marked on the surface of the support vertical plate 22 near the LED light strip 23, and the values ​​on the scale mark 24 increase from bottom to top.

[0049] refer to Figure 5 .

[0050] Through the marking of the scale indication 24, the specific LED light bar 23 on the supporting vertical plate 22 can be lit up to display the corresponding numerical value for accurately judging the specific numerical value of the water level. In addition, in a night environment, the lighting of the LED light bar 23 can illuminate the scale indication 24 and the numerical scale nearby, making it convenient to read data at night.

[0051] Furthermore, a solar panel assembly 25 is fixedly connected to the top of the support vertical plate 22, and the solar panel assembly 25 is electrically connected to the rechargeable battery.

[0052] refer to Figure 5 By setting up the solar panel assembly 25, solar energy can be collected during daily use, so that the solar energy is converted into electrical energy and stored in the rechargeable battery to meet the daily power demand.

[0053] Furthermore, there are two limit rods 4 , and the two limit rods 4 are symmetrically arranged with respect to the vertical center line of the floating plate 2 .

[0054] refer to Figure 1 Through the symmetrical arrangement of the two limit rods 4, the force on the floating plate 2 is more balanced, and it will be more stable during movement, ensuring stability in a long-term use environment.

[0055] Working principle: When the geological exploration groundwater level monitoring device is used, it is supported and fixed by an external frame through the support ring 1, so that the support ring 1 can support the rotating column 5 when it rotates.

[0056] The floating plate 2 floats on the liquid surface of the water area to be detected, so that the change of the water level in the water area can be sensed through the ups and downs of the floating plate 2;

[0057] The limiting rod 4 is supported and connected by the connecting column 3, and the limiting rod 4 penetrates the floating plate 2, so that the movement trajectory of the floating plate 2 is restricted and can only be lifted and lowered axially.

[0058] The bottom of the lifting rack 10 is in contact with the upper surface of the floating plate 2, so that the weight of the lifting rack 10 is pressed on the floating plate 2, and the floating plate 2 will be close to the liquid surface. When the water level rises, the floating plate 2 will float synchronously, and the floating floating plate 2 will drive the lifting rack 10 to move upward synchronously. Since the lifting rack 10 passes through the horizontal plate 11, its movement trajectory is also limited, and it can only be lifted axially. The upward movement of the lifting rack 10 of Banu Si, the gear 9 meshing with the teeth on the lifting rack 10 will drive the horizontal rotating rod 8 to rotate on the side support plate 7, and the water level monitoring surveillance camera 12 fixed on the end of the horizontal rotating rod 8 will rotate synchronously with the horizontal rotating rod 8. When the water level changes, the water level monitoring surveillance camera 12 will realize dynamic detection of the water level through continuous rotation, and the detection range is more comprehensive;

[0059] By setting the adjustment device, the water level monitoring camera 12 can further adjust its position in the horizontal direction when the water level changes, so as to obtain more comprehensive monitoring data;

[0060] refer to Figure 1 , Figure 2 and Figure 3 As mentioned above, the floating plate 2 can only be raised and lowered axially due to the limitation of the positioning rod 4. When the water level rises, the floating plate 2 rises synchronously, and the guide slider 17 on the inner wall of the movable through hole 16 will move up along the inner wall of the outer spiral groove 18. Under the guidance of the spiral track on the outer spiral groove 18, the vertical rotating rod 13 will lead the rectangular sliding rod 14, and the rectangular sliding rod 14 will lead the rotating column 5 to rotate in the support ring 1. From then on, the connecting frame 6, side support plate 7, horizontal rotating rod 8, gear 9, lifting rack 10, cross plate 11 and water level monitoring surveillance camera 12 on the rotating column 5 will rotate with the vertical center line of the rotating column 5 as the rotation center.

[0061] In conjunction with the previous rotation of the water level monitoring surveillance camera 12 along with the horizontal rotating rod 8, the rotation range of the water level monitoring surveillance camera 12 is further enriched, and the monitoring range of the water level monitoring surveillance camera 12 for water level changes in the water area is further improved.

[0062] By setting up the display device, the change of water level can be visualized and presented in data form, so that people can quickly obtain the water level change situation on site;

[0063] refer to Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 7 .

[0064] As the floating plate 2 moves up and down, the guide slider 17 will be in contact with and squeezed with the rubber sealing tubes 19 at different locations on the inner wall of the outer spiral groove 18, so that the pressure-sensitive switch module 20 wrapped in the rubber sealing tube 19 is also squeezed synchronously. Since the contact between the guide slider 17 and the rubber sealing tube 19 is continuous, the squeezing of the pressure-sensitive switch module 20 is also continuous and linear. Finally, for the multiple pressure-sensitive switch units 21 constituting the pressure-sensitive switch module 20, the multiple pressure-sensitive switch units 21 are squeezed one by one. Figure 4 , referring to the above, the pressure-sensitive switch units 21 correspond to the LED light strips 23 one by one and are electrically connected by the rechargeable battery. When the multiple pressure-sensitive switch units 21 in the above content are squeezed one by one, the LED light strips 23 electrically connected to the corresponding pressure-sensitive switch units 21 will be powered on and light up. As mentioned earlier, the multiple pressure-sensitive switch units 21 are also squeezed one by one, that is, the multiple LED light strips 23 distributed on the supporting vertical plate 22 are also lit up one by one, that is, the multiple LED light strips 23 are linearly lit up one by one from bottom to top or from top to bottom on the supporting vertical plate 22, and the lighting speed is affected by the speed of water level rise;

[0065] At this point, on site, people can roughly judge the water level by observing the position of the lights on the support vertical plate 22, referring to Figure 5 .

[0066] Through the marking of the scale indication 24, the specific LED light bar 23 on the supporting vertical plate 22 can be lit up to display the corresponding numerical value for accurately judging the specific numerical value of the water level. In addition, in a night environment, the lighting of the LED light bar 23 can illuminate the scale indication 24 and the numerical scale nearby, making it convenient to read data at night.

[0067] Through the coordinated use of the above structures, the problem of inconvenience in actual use caused by the existing water level monitoring equipment mostly monitoring the water area to be surveyed at a fixed angle and the monitoring results are not comprehensive enough, especially when the water level changes, it is difficult to quickly observe the water level of the water area from multiple angles, which brings inconvenience to the use is solved.
