[0002] Underwater topographic surveying is a specific type of engineering surveying. It involves measuring the planar position and elevation of points on the seabed of rivers, lakes, reservoirs, harbors, and nearshore waters to create underwater topographic maps. Among the related technologies, the most commonly used methods in routine underwater topographic surveying are depth sounder (single-beam and multi-beam) surveying and depth sounder rod surveying. Metal reflective signal rods are frequently used in scenarios such as water boundary marking, geological exploration, and hydrological monitoring to provide feedback on geological and hydrological data.

[0003] In loose strata such as silt and soft soil, traditional fixed markers are fixed by manual insertion. The existing technical solutions mentioned above have the following drawbacks: manual insertion is prone to tilting or sinking due to unstable foundation, which leads to increased positioning error and tilting after long-term use. Summary of the Invention

[0004] The purpose of this invention is to provide a pre-set metal reflective signal rod for insertion into silt, in order to solve the technical problems that manual insertion is prone to tilting or sinking due to unstable foundation, resulting in increased positioning errors and easy tilting after long-term use, thereby improving the stability and operational efficiency of the signal rod when inserted into silt.

[0005] To solve the above-mentioned technical problems, this utility model provides a pre-set metal reflective signal rod for insertion into silt, including a frame and a signal rod fixed to the bottom of the frame.

The bottom end of the shaft is fixedly connected to the movable disc. The surface of the movable disc has two opposing arc-shaped grooves, and a connecting rod is slidably connected in each of the two arc-shaped grooves.

[0008] The bottom of the fixed plate is also provided with a guide for the two connecting rods to slide, and the bottom of the two connecting rods are respectively fixedly connected to one end of the two movable plates.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] Example:

[0024] As shown in Figures 1 to 4, a pre-set metal reflective signal rod for insertion into silt includes a frame and a signal rod fixed to the bottom of the frame. The signal rod is a metal reflective signal rod. The frame also has two movable plates and an extension assembly for driving the two movable plates to move in a telescopic motion. Support plates are slidably installed on the inner side of the two movable plates. The top of the two movable plates is also provided with a driving component for driving the two support plates to move up and down. When the device is moved to the surface of the silt, the driving component is rotated to start, which drives the extension assembly to unfold the movable plates. The movable plates extend outward to expand the support range. The support plates are adjusted to a suitable height by adjusting screws. The signal rod is vertically inserted into the silt under the stabilizing effect of the support plates.

[0025] It should be noted that, referring to Figures 1 and 2, the driving component includes two adjusting screws. The two adjusting screws are respectively threaded to the top of the two movable plates, and the bottom ends of the two adjusting screws are respectively rotatably connected to the two support plates. Rotating the adjusting screws drives the support plates to rise and fall along the inner side of the movable plates through threaded transmission. The bottom of the support plates contacts the ground or silt surface, providing reverse support force to prevent the device from tilting. By adjusting the height of the two support plates, the verticality of the device can be corrected to adapt to uneven terrain.

[0026] In a specific implementation process, referring to Figures 2 and 3, the extension assembly includes a fixed plate, a movable plate, a shaft, and a rotary motor. The rotary motor is fixedly installed on the top of the frame. The rotor end of the rotary motor passes through the frame and the fixed plate respectively and is fixedly connected to the top of the shaft. The fixed plate is fixedly installed inside the frame. The bottom end of the shaft is fixedly connected to the movable plate. The surface of the movable plate has two opposing arc-shaped grooves, and a connecting rod is slidably connected in both arc-shaped grooves. The connecting rod is connected to the movable plate in an integral structure.

[0027] It should be noted that, as shown in Figures 3 and 4, the bottom of the fixed plate is also provided with guides for the sliding of the two connecting rods. The bottom of the two connecting rods is fixedly connected to one end of the two movable plates respectively. The rotary motor drives the shaft to rotate, which drives the movable plate to rotate synchronously. The arc groove on the movable plate slides in cooperation with the connecting rod. When the movable plate rotates, the connecting rod moves along the arc groove trajectory. The connecting rod slides linearly in a fixed direction (such as the horizontal direction) through the guidance of the sliding plate and the slide rail. The bottom of the connecting rod is integrally connected to the movable plate, which drives the movable plate to extend and retract synchronously, expanding or contracting the support range of the device.

[0028] As further explained in Figure 4, the guide includes a slide rail and a slide plate. The slide rail is fixedly installed on the bottom of the fixed plate, and the slide plate is slidably installed inside the slide rail. The bottom end of the slide plate is fixedly connected to the connecting rod.

[0029] In summary, the working principle provided by this utility model is as follows: When the device is in use, it is moved to the surface of the silt. The rotating motor drives the shaft to rotate, which in turn drives the movable disc to rotate synchronously. The arc groove on the movable disc slides in cooperation with the connecting rod. When the movable disc rotates, the connecting rod moves along the trajectory of the arc groove. The connecting rod slides linearly in a fixed direction (such as the horizontal direction) through the guidance of the sliding plate and the slide rail. The bottom of the connecting rod is integrally connected to the movable plate, which drives the movable plate to extend and retract synchronously, expanding or contracting the support range of the device. Rotating the adjusting screw drives the support plate to rise and fall along the inner side of the movable plate through threaded transmission. The bottom of the support plate contacts the ground or the surface of the silt, providing reverse support force to prevent the device from tilting. By adjusting the height of the support plates on both sides, the verticality of the device can be corrected to adapt to uneven terrain.
