[0002] Water conservancy projects are a general term for various engineering constructions undertaken to control, utilize, and protect surface and groundwater resources and the environment. They are projects built to control and regulate surface and groundwater in nature to achieve the purpose of eliminating harm and promoting benefits. Hydrological departments need to monitor various hydrological information in the region year-round to provide hydrological data for various national construction plans and play an important role in the development planning around the river. Based on actual conditions, the more, more complete, and more accurate the hydrological information monitored by the hydrological department, the better.

[0045] Beneficial effects

[0046] The flood mark monitoring equipment according to various embodiments of the present invention, compared with traditional monitoring equipment, allows for easier adjustment of the monitoring position, which helps ensure the accuracy of monitoring data, and has the function of measuring flood water level, ensuring the comprehensiveness of monitoring data; thus laying the foundation for obtaining effective flood mark monitoring data.

[0047] Furthermore, by incorporating gears A and B, the two sets of threaded rods can rotate simultaneously, thereby enabling the connecting frame to move up and down. This allows for the adjustment of the positions of the first and second floats based on the initial water level. The inclusion of arrayed rollers and H-shaped sliders enhances the sliding effect of the connecting frame. Compared to existing floodmark monitoring equipment, this design simplifies the adjustment of the monitoring equipment's position, thus ensuring data accuracy.

[0048] Furthermore, by setting up two sets of control gears and two sets of toothed plates, the control frame is able to drive the first and second monitoring devices to move horizontally, thus enabling flood mark monitoring at multiple locations. Compared with existing flood mark monitoring equipment, it can more easily achieve the effect of monitoring multiple locations, which helps to improve the comprehensiveness of monitoring data.

[0049] Furthermore, by incorporating a self-locking rod, a self-locking component, a spring component, and a right-angle tooth, the right-angle tooth, through the inclined side of the self-locking component, drives the self-locking rod to slide backward when the monitoring column moves upward. This achieves the purpose of easily and conveniently fixing the monitoring column when the right-angle side of the self-locking component aligns with the right-angle side of the right-angle tooth. This enables rapid and effective monitoring of flood peak values ​​and helps reduce errors in monitoring data.

[0050] Furthermore, by incorporating a second float, the vertical rod is able to move upward following the monitoring column; and by utilizing the vertical rod in conjunction with the spring and the second float, the ranging sensor B is able to move downward following the water level. This enables a quick and simple monitoring of flood levels and receding speed, and more effectively improves the comprehensiveness of the data.

[0051] In addition, by setting gear C and the internal gear ring of the monitoring frame, the camera can be easily and conveniently rotated. By using the control module in conjunction with the monitoring shaft and motor device, the rotation angle of the camera can be controlled, thus playing a role in monitoring the flood environment and data around the river.

Under the action of the elastic rubber component, the stability of the monitoring equipment is ensured when adjusting the monitoring equipment.

[0083] The specific usage and function of this embodiment are as follows: In this invention, the device is fixed to the edge of the river by the fixing device 1. The motor device at the top of the support frame 101 is started to drive the gear B203 to rotate. The gear B203 simultaneously drives the two sets of gears A202 to rotate. The gears A202 drive the connecting frame 301 to move up and down through the threaded rod 201, so that the bottom of the second float 802 is in contact with the water surface and the top of the second float 802 is in contact with the bottom of the first float 603. The motor device inside the protective cover 502 is started to drive the control gear 503 to rotate. The control gear 503 drives the gear plate 302 to rotate. The control frame 501 moves horizontally. When the water level rises, buoyancy pushes the second float 802 and the first float 603 upwards. The first float 603 moves the monitoring column 601 upwards. The monitoring column 601 pushes the self-locking component 505 and the self-locking rod 504 backwards through the hypotenuse of the right-angle tooth 602. When the water level stops rising, the spring component moves the self-locking rod 504 and the self-locking component 505 forwards, causing the right-angle side of the self-locking component 505 to engage with the right-angle side of the right-angle tooth 602, thus fixing the monitoring column 601 relatively and preventing it from sliding downwards. This achieves rapid and effective monitoring of flood peaks. Functions: The monitoring column 601 uses a distance sensor A605 at its top to monitor and collect data on flood peaks. When the flood level drops, the second float 802 and the vertical rod 801 slide downwards under the influence of gravity via springs, ensuring the bottom of the second float 802 remains in contact with the water surface. This provides a quick and simple way to monitor the flood level and the rate of flood recession. The distance sensor B803 monitors and records the receding flood level. The control module 604 activates the motor at the top of the monitoring shaft 703, driving the shaft and gear C704 to rotate. A synchronous pulley and belt work together to achieve [the desired effect]. The simultaneous rotation of the three monitoring shafts 703; the gear C704 drives the monitoring frame 702 and camera 705 to rotate through the internal gear ring of the monitoring frame 702; achieving the effect of easily and conveniently driving the camera 705 to rotate; using the control module 604 in conjunction with the monitoring shafts 703 and the motor device, the rotation angle of the camera 705 is controlled, playing a role in monitoring the flood environment and data around the river; the spring between the top of the sliding part 403 and the top of the buffer rod 402 ensures the stability of the monitoring equipment when adjusting it.

[0084] Finally, it should be noted that when describing the position of each component and the mating relationship between them, the present invention usually uses one or a pair of components as examples. However, those skilled in the art should understand that such positions, mating relationships, etc., are also applicable to other components or other pairs of components.

[0085] The above description is merely an exemplary embodiment of the present invention and is not intended to limit the scope of protection of the present invention, which is determined by the appended claims.
