[0039] The nozzle 16 can discharge the water flow collected by the receiving pipe 15 onto the surface of the camera 24.

[0040] As Figure 7, the transmission device 11 includes a support side frame 19, a propeller 20, a power system 18, and a support top frame 22.

[0043] When the protection side frame 27 contacts the outside world, the top end of the protection side frame 27 can be displaced to contact the optoelectronic sensor 23, so that the optoelectronic sensor 23 can emit a signal.

[0044] Such as Figure 9 , the synchronization device 13 includes a hydraulic cylinder 32, a positioning top frame 31, and an extension cross plate 34. The hydraulic cylinder 32 is fixedly installed at the center of the top end of the positioning top frame 31. The extension cross plate 34 is fixedly installed at the bottom end of the hydraulic cylinder 32. Four racks 35 are fixedly installed at the bottom of the outer ring of the hydraulic cylinder 32, and the racks 35 are located above the extension cross plate 34. Four collection plates 33 can be rotatably installed on both sides inside the positioning top frame 31. A transmission gear 36 is fixedly installed at the center of the side end of the collection plate 33 close to the hydraulic cylinder 32. A connecting rope 37 is fixedly installed on the outer ring of the collection plate 33. By vertically aligning the extension cross plate 34 with the contact cross plate 17, when the extension cross plate 34 rises, it can drive the contact cross plate 17 to tilt upward;

[0045] When the piston rod inside the hydraulic cylinder 32 moves up and down, it can drive the rack 35 to pass through the transmission gear 36, thereby driving the collection plate 33 to rotate.

[0046] The positioning top frame 31 is fixedly installed at the bottom end of the wire rope 6, the receiving pipe 15 is fixedly installed at the top end of the extension bracket 21, the supporting top frame 22 is fixedly installed at the top end of the supporting cavity 30, the supporting top frame 22 is fixedly installed at the bottom end of the positioning top frame 31, one end of the connecting rope 37 far from the transmission gear 36 is connected to the movable rod 29, the worm 2 meshes with the worm gear 8, the receiving pipe 15 is horizontally aligned with the propeller 20, the nozzle 16 is obliquely aligned with the camera 24, movable grooves are symmetrically formed inside the supporting top frame 22, and the movable rod 29 is located inside the movable grooves. A sealing system is fixedly installed at the inner top end of the positioning top frame 31, and the sealing system covers the hydraulic cylinder 32 and the piston rod. The transmission gear 36 meshes with the rack 35. Square grooves are formed on both sides of the positioning top frame 31, and the bottom end of the power system 18 is in contact with the inner bottom end of the square grooves. The top side end of the protective side frame 27 is horizontally aligned with the photoelectric sensor 23;

[0047] The sealing system includes the following components:

[0048] Cylinder seal: Cylinder upper end and cylinder lower end are sleeved at both ends of the cylinder, and cylinder seals are embedded at the connection with the cylinder to prevent water from seeping in at the connection between the cylinder and the upper and lower ends of the cylinder;

[0049] Piston seal: A piston head is sleeved inside the cylinder, and a piston rod is fixedly sleeved in the middle of the piston head. First piston seals and second piston seals are embedded at the upper and lower ends of the side surface of the piston head to prevent gas or liquid from leaking through the gap between the piston and the cylinder;

[0050] Dynamic rubber seal: Multiple layers of dynamic rubber seals for waterproofing are provided at the contact surface between the cylinder upper end and the piston rod to reduce the amount of water adhering to the surface of the piston rod during its reciprocating motion underwater and prevent water from entering the inside of the cylinder.

[0051] A method for observing the groundwater level of a hydrogeological exploration, which includes the following steps:

[0052] S1. First, place the support base frame 9 on the designated groundwater exploration area, then start the drive motor 3 to drive the worm 2 and the worm gear 8 to rotate simultaneously, so that the wire rope 6 can be released by the winding wheel 7, and thus the lower edge component 5 can enter below the water surface;

[0053] S2. Subsequently, by bringing the detection head 25 into contact with water and keeping the detection head 25 turned on, the detection head 25 can sink as a whole with the lower edge component 5 to observe water at different depths. At the same time, the setting of the camera 24 facilitates the user to observe the underwater state. Moreover, the setting of the detection radar 28 enables the user to understand the movement trajectory of the support cavity 30 on the control terminal, reducing the probability of collision between the support cavity 30 and the underground wall. Meanwhile, the setting of the protective side frame 27 enhances the protection of the support cavity 30 and prevents the detection radar 28 from being damaged by impact;

[0054] S3. Finally, when the support cavity 30 is trapped, the hydraulic cylinder 32 can be activated to drive the extension cross plate 34 to move upward, causing the extension cross plate 34 to push the power system 18 to rotate upward, resulting in the propeller 20 tilting downward. When the propeller 20 is working, it can drive the entire support cavity 30 to move upward. Moreover, when the extension cross plate 34 moves upward, when the rack 35 passes through the transmission gear 36, the connecting rope 37 can pull the protective side frame 27 to move towards one end close to the support cavity 30, enabling the protective side frame 27 to be retracted, facilitating the removal of the support cavity 30 from the trapped terrain and completing the work.

[0055] The working principle of Embodiment 1 is as follows: When in use, first move and place the support base frame 9 on a designated area in the outside world until the lower edge component 5 is vertically aligned with the groundwater hole. Then, start the drive motor 3 to drive the worm 2 to rotate. Through the meshing of the worm 2 and the worm gear 8, when the worm 2 drives the worm gear 8 to rotate, the wire rope 6 can be released by the wire rope reel 7 and move downward, so that the entire lower edge component 5 can enter below the water surface. Subsequently, since the camera 24, the detection head 25, and the detection radar 28 are wirelessly connected to an external control terminal, the camera 24 and the detection head 25 can be turned on, enabling the detection head 25 to detect the water quality. At the same time, through the setting of the camera 24, the state of the groundwater can be observed. And when the entire support cavity 30 moves downward, through the setting of the detection radar 28, signals can be emitted to the surrounding area, enabling the detection radar 28 to sense the distance from the underground terrain, reducing the probability of the support cavity 30 directly hitting the terrain. At the same time, when the support cavity 30 hits the terrain, since the protective side frame 27 is located at the side of the detection radar 28, the protective side frame 27 will contact the terrain, thereby preventing the detection radar 28 from being damaged by the impact. At the same time, through the setting of the return spring 26, the protective side frame 27 is allowed to displace towards the end close to the support cavity 30 when being impacted. At the same time, when the protective side frame 27 moves inward to the limit position, it can contact the photoelectric sensor 23. Since the photoelectric sensor 23 is wirelessly connected to an external control terminal, the photoelectric sensor 23 can send an alarm to the control terminal to prompt the operator that the support cavity 30 has collided with the terrain. When the wire rope reel 7 rotates, the wire rope 6 can be released, enabling the detection head 25 to sink to a designated depth for water quality observation work. When the support cavity 30 is trapped in the terrain, the hydraulic cylinder 32 can be turned on, so that the piston rod at the bottom of the hydraulic cylinder 32 can drive the extension cross plate 34 and the rack 35 to move upward, causing the extension cross plate 34 to push the contact cross plate 17 to drive the power system 18 and the propeller 20 to rotate and tilt towards the side of the extension bracket 21. Thus, the propeller 20 can work in an inclined state. At this time, when the propeller 20 is working, it can eject the water flow downward, enabling the entire support cavity 30 to move upward, providing an upward thrust. At the same time, when the rack 35 moves upward, it can drive the transmission gear 36 and the collection tray 33 to rotate, causing the collection tray 33 to pull the movable rod 29 and the protective side frame 27 to displace towards the end close to the camera 24 through the connecting rope 37, so that the two protective side frames 27 can be retracted to prevent the protective side frames 27 from getting stuck between the terrain. Subsequently, when the power system 18 is started, it can drive the propeller 20 to rotate, enabling the propeller 20 to drive the support cavity 30 to move upward, completing the work of quickly rescuing the support cavity 30. Then, start the hydraulic cylinder 32 again to drive the extension cross plate 34 and the rack 35 to reset downward, so that the power system 18 and the propeller 20 can be placed horizontally again, facilitating the propeller 20 to inject the water flow into the interior of the receiving pipe 15 when working.It is internally communicated with the inside of the nozzle 16 through the connecting pipe 14, and the nozzle 16 is inclined and aligned with the surface of the camera 24, so that the water flow can be sprayed from the nozzle 16 to the surface of the camera 24, and the plankton attached to the surface of the camera 24 can be removed, improving the imaging clarity of the camera 24. A sealing system is installed on the hydraulic cylinder 32 and the internal piston rod, so as to prevent water from seeping into the inside of the hydraulic cylinder 32. Moreover, when the rack 35 moves downward and resets, the transmission gear 36 can release the connecting rope 37. At this time, the elastic force of the return spring 26 will drive the protective side frame 27 to reset outward, so that the protective side frame 27 can perform normal protection work. When the device is in use, the connecting shaft inside the power system 18 is connected to the propeller 20. When the power system 18 is started, the propeller 20 can be driven to rotate. When the propeller 20 rotates, the whole support cavity 30 can be driven to displace, so as to facilitate the support cavity 30 to avoid obstacles, improve the smoothness of the descent of the support cavity 30, and facilitate the support cavity 30 to enter a deeper area for observation. When the device is in use, a sealing system is installed on the periphery of the power system 18, so as to prevent the electronic components inside the power system 18 from contacting water and improve the service life of the power system 18, and the work is completed.

[0056] Embodiment 2

[0057] On the basis of Embodiment 1, as Figure 10 shown, the support base frame 9 further includes a screw rod 38, an extension wing plate 39 and a positioning round rod 40. The extension wing plates 39 are symmetrically and fixedly installed at the bottom ends of both ends of the support base frame 9. The screw rod 38 is threadedly inserted into the top end inside the extension wing plate 39, and the positioning round rod 40 is fixedly installed at the center of the bottom end of the screw rod 38.

[0058] When implementing this embodiment, first open a hole corresponding to the positioning round rod 40 on the ground, then move the support base frame 9 to the ground until the positioning round rod 40 is aligned with the previously opened hole, and then rotate the screw rod 38, so as to drive the positioning round rod 40 to insert into the hole, so as to prevent the support base frame 9 from shaking during use and improve the use stability of the support base frame 9, and the work is completed.
