[0041] Based on the water level monitoring device for hydrological engineering geology in embodiment 1, the preferable embodiment of the utility model further comprises Figures 1 to 6 As shown in the figure, the positioning assembly 3 comprises: a fixed groove 302 formed on one side of the top end of the fixed seat 5; a positioning block 307 slidably connected in the fixed groove 302, one end of the positioning block 307 extending into the sliding groove 14, and the other end of the positioning block 307 fixedly connected with a pull rod 304 extending out of the fixed groove 302; a fixed spring 305 wound on the surface of the pull rod 304, the two ends of the fixed spring 305 fixedly connected with the inner wall of the fixed groove 302 and one end of the positioning block 307 respectively; positioning grooves 301 equidistantly formed on one side of the lifting rod 13; and a positioning hole 308 formed on the inner wall of the sliding groove 14.

[0042] In the embodiment, the lifting rod 13 is pulled to slide to a suitable height, and then the elastic force of the fixed spring 305 is used to make the positioning block 307 pass through the suitable positioning groove 301 and clamp into the positioning hole 308, so that the lifting rod 13 is fixed after sliding, and the height between the bottom end of the water level radar 6 and the ground can be changed to meet the water level monitoring operation under different conditions.

[0043] In the further preferable embodiment of the utility model, the inner wall of the fixed groove 302 is provided with a sliding groove 303, and the two sides of one end of the positioning block 307 are fixedly connected with sliding blocks 306 slidably matched with the inner part of the sliding groove 303.

[0044] In the embodiment, the sliding of the sliding blocks 306 in the sliding groove 303 improves the stability of the back-and-forth sliding of the positioning block 307.

[0045] The further preferable embodiment of the utility model further relates to a positioning block 307, one end of the positioning block 307 penetrates through the positioning groove 301 and forms a clamping structure with the inside of the positioning hole 308, and the fixing groove 302 and the positioning hole 308 are located in the same horizontal plane.

[0048] In the embodiment, the sliding of the I-shaped lifting rod 13 and the inside of the sliding groove 14 is utilized to improve the stability of the up-down sliding of the lifting rod 13.

[0049] The further preferable embodiment of the utility model further relates to a moving assembly 2, which comprises a moving threaded rod 203 rotatably connected at the middle position of the inner wall of a fixed frame 7, a threaded seat 201 threadedly connected to the surface of the moving threaded rod 203, and a bolt fixedly connecting between the bottom end of the threaded seat 201 and the top end of a water level radar 6; a moving servo motor 202 fixedly connected to one side of the fixed frame 7, and an output end of the moving servo motor 202 fixedly connected with one end of the moving threaded rod 203 through a shaft coupling.

[0050] In the embodiment, the moving threaded rod 203 is driven to rotate by starting the moving servo motor 202, the threaded seat 201 is slid back and forth by the threaded cooperation of the moving threaded rod 203 and the threaded seat 201, the water level radar 6 is slid back and forth by the threaded seat 201, and the water level monitoring range of the water level radar 6 is improved.

[0052] In the embodiment, the sliding between the sliding rod 204 and the threaded seat 201 is utilized to avoid the rotation of the threaded seat 201 along with the rotation of the moving threaded rod 203, and the back-and-forth sliding of the threaded seat 201 is more stable.

[0053] The working principle of this utility model is as follows: First, the fixing seat 5 is installed and fixed in a suitable position using external bolts. Then, by pulling the pull rod 304, the positioning block 307 is slidably compressed and the fixing spring 305 is completely separated from the positioning groove 301 and the positioning hole 308. After that, the lifting rod 13 is pulled to slide to a suitable height. Then, the pull rod 304 is released. Using the elastic force of the fixing spring 305, the positioning block 307 passes through the suitable positioning groove 301 and is locked into the positioning hole 308, thereby achieving the limit fixation of the lifting rod 13 after sliding. This allows the height between the bottom of the water level radar 6 and the ground to be changed, so as to meet the water level monitoring operation under different conditions.

[0054] Then, the moving servo motor 202 can be started to drive the moving threaded rod 203 to rotate. The threaded engagement between the moving threaded rod 203 and the threaded seat 201 causes the threaded seat 201 to slide back and forth, thereby driving the water level radar 6 to slide back and forth, increasing the water level monitoring range of the water level radar 6. Water level monitoring can then be performed through the water level radar 6. When the water level is high and reaches the warning line, the alarm information can be remotely transmitted to the external control terminal through the wireless data transmitter 11 to inform the staff.

[0055] Meanwhile, when it rains, after being filtered by the filter frame 104, the rainwater flows into the water storage tank 101 and is then guided by the guide plate 106, allowing the filtered rainwater to be discharged more quickly through the drainage channel 111. Because the drainage channel 111 has a small internal width, the rainwater flows out quickly to rinse the surface of the photovoltaic panel 8. At this time, the cleaning servo motor 108 drives the cleaning threaded rod 103 to rotate. The threaded engagement between the cleaning threaded rod 103 and the threaded block 109 causes the threaded block 109 to slide, driving the flexible soft brush 110 to slide back and forth, facilitating the wiping and cleaning of the surface of the photovoltaic panel 8. This cleans the surface of the photovoltaic panel 8 and prevents excessive dust and other impurities from adhering to the surface of the photovoltaic panel 8, which would affect the conversion effect of the photovoltaic panel 8. At the same time, the flexible soft brush 110 can be disassembled periodically for thorough cleaning. The handle on the filter frame 104 can be pulled to disassemble the filter frame 104 for centralized disposal of fallen leaves and other impurities filtered by the filter frame 104.

[0056] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires, and should select appropriate controllers according to actual conditions to meet control requirements. The specific connection and control sequence should refer to the working principle described above, and the electrical connection should be completed by referring to the working sequence of each electrical component. The detailed connection methods are well-known technologies in the field. The above mainly introduces the working principle and process, and will not describe the electrical control.

[0057] The above merely describes the preferred embodiments of the present application, and is not intended to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
