They are widely used in rivers, waterways, reservoirs, and harbors, enabling rescue and salvage operations, water quality sampling, and waterway mapping.
[0005] Unmanned boats sail autonomously on the water, carrying out a series of inspections on the water using detection equipment. However, in the actual inspection process, they are often affected by factors such as strong winds, centrifugal force of steering, and emergency acceleration and deceleration, which increase the difficulty of autonomous control of the unmanned boat during driving. This will also affect the accuracy of the measurement by affecting the stability of the unmanned boat's shape. Utility Model Content

[0013] In one possible implementation, the positioning frame is composed of two symmetrical plates, which are respectively buckled onto the outside of the support ball seat by the top and bottom of the support ball seat, and are adapted to be connected to the outside of the support ball seat through processed grooves. The positioning frame is assembled and connected to the inner wall of the unmanned boat body.
[0014] In one possible implementation, the second rod assembly is composed of multiple circular tubes with different diameters, and the multiple circular tubes are connected step by step in a manner of decreasing diameter to support the extension or contraction of the second rod assembly.

[0028] The technical solution in the embodiments of the present application is to solve the problems of the above-mentioned background technology, and the overall idea is as follows:
[0029] Example 1:
[0030] This embodiment introduces the specific structure of a hard frame front support type high stability unmanned boat. Figure 1-Figure 5 As shown, it includes an unmanned boat body 2, a detection probe rod assembly 1 (assembled on the head of the unmanned boat body 2, and the whole is in the shape of a triangular pyramid), a posture follower structure arranged at the top of the inner side of the unmanned boat body 2 and a center of gravity adjustment structure arranged at the bottom of the inner side of the unmanned boat body 2, the detection probe rod assembly 1; the center of gravity adjustment structure includes a counterweight seat 11, the top of the counterweight seat 11 is cooperatively connected with a driving ball 13, and the top of the driving ball 13 is fixedly connected with a second rod assembly 9 (composed of a plurality of circular tubes with different diameters). By making the plurality of circular tubes gradually sleeved in a manner of decreasing diameter, and making one end of the circular tube located on the outermost side threadedly connected to the top of the driving ball 13, and one end of the circular tube located on the innermost side threadedly connected to the bottom of the supporting ball seat 12, the demand for extension or contraction of the second rod assembly 9 can be met, so that when the counterweight seat 11 moves at the bottom of the unmanned boat body 2, the second rod assembly 9 rotates around the supporting ball seat 12 to extend or contract;
[0031] like Figure 2 and Figure 4As shown, the posture following structure includes a first rod assembly 4 (the first rod assembly 4 is composed of two round tubes with different diameters, and the first rod assembly 4 and the second rod assembly 9 maintain a coaxial state), one end of the first rod assembly 4 is assembled with a universal joint 6, one end of the universal joint 6 is assembled with a vertical rod 5, and one end of the vertical rod 5 is processed with an adjustment disc 7. By making one round tube sleeved on the outside of the other round tube, one end of the round tube located on the inner side is threadedly connected to the top of the support ball seat 12, and one end of the round tube located on the outer side is threadedly connected to one end of the universal joint 6, so that when the adjustment disc 7 moves with the tilt of the unmanned boat body 2 at the top of the support partition 3, one end of the first rod assembly 4 moves with the adjustment disc 7 through the universal joint 6, while the other end rotates around the support ball seat 12;
[0032] Among them, the connection line between the attitude follower structure and the center of gravity adjustment structure is set vertically, and a support ball seat 12 is set between one end of the first rod assembly 4 and one end of the second rod assembly 9. A positioning frame 8 (composed of two upper and lower symmetrical plates) is set on the outside of the support ball seat 12. By making the two plates buckle to the outside of the support ball seat 12 at the top and bottom of the support ball seat 12 respectively, and adapting and connecting to the outside of the support ball seat 12 through the processing groove, when the positioning frame 8 is assembled and connected to the inner wall of the unmanned ship body 2, the two plates constituting the positioning frame 8 can be used to support the rotation of the support ball seat 12;
[0033] Secondly, a supporting baffle 3 is provided at the bottom of the adjusting disc 7. When the unmanned boat body 2 carrying the detection probe assembly 1 is disturbed on the water surface or tilted due to changes in its own driving state, the adjusting disc 7 follows the action posture of the unmanned boat body 2 and moves on the top of the supporting baffle 3. At this time, the first rod assembly 4 is used to control the second rod assembly 9 to rotate around the supporting ball seat 12, pushing the counterweight seat 11 at the bottom of the driving ball 13 to move in the opposite direction of the moving direction of the adjusting disc 7 at the bottom inner wall of the unmanned boat body 2 (based on the first rod assembly 4 and the second rod assembly). The length ratio between the components 9 is that the length of the first rod component 4 is longer than the length of the second rod component 9, and the weight of the adjusting disc 7 is less than the weight of the counterweight seat 11). When the adjusting disc 7 tilts to one side, the tendency of the counterweight seat 11 to tilt to one side can be overcome, and the counterweight seat 11 can be pried in the opposite direction by driving the ball 13, so that when the attitude following structure tilts following the driving state of the unmanned boat body 2, the center of gravity adjusting structure moves in the opposite direction of the attitude following structure, so as to achieve the effect of adjusting the overall center of gravity of the unmanned boat body 2 and achieving the effect of stabilizing the unmanned boat body 2;
[0034] Furthermore, in order to facilitate the connection between the driving ball 13 and the counterweight seat 11, the driving ball 13 can rely on its own gravity and the second rod assembly 9 rotating around the supporting ball seat 12 to move the counterweight seat 11 on the bottom inner wall of the unmanned boat body 2, as shown in FIG. Figure 5As shown, a positioning ball groove 14 is machined on the top surface of the counterweight seat 11, and universal wheels 10 are provided at the four corners of the bottom of the counterweight seat 11. By making the driving ball 13 fit and connect inside the positioning ball groove 14, and making the driving ball 13 movably connected inside the positioning ball groove 14, the positioning ball groove 14 on the top of the counterweight seat 11 can be used to position the driving ball 13, restricting the driving ball 13 from moving on the top surface of the counterweight seat 11, ensuring that the second rod assembly 9 controls the stability of the counterweight seat 11 through the driving ball 13;
[0035] At the same time, in order to ensure that the center of gravity of the counterweight seat 11 itself is not increased by the setting of the universal wheel 10, Figure 4 and Figure 5 As shown, the four corners of the bottom of the counterweight seat 11 are each provided with a receiving groove 15. By assembling the universal wheel 10 to the top inner wall of the receiving groove 15, the receiving groove 15 can be stored inside the counterweight seat 11. When the bottom of the universal wheel 10 protrudes from the bottom surface of the counterweight seat 11, the universal wheel 10 can be used to roll and connect to the bottom inner wall of the unmanned boat body 2, thereby reducing the movement resistance of the counterweight seat 11.
[0036] Furthermore, in order to enable the adjustment disc 7 to move in various directions on the top of the supporting partition 3 in the horizontal plane, Figure 4 As shown, a circular groove is processed inside the supporting partition 3, and the diameter of the adjusting disc 7 is larger than the diameter of the circular groove. By assembling the supporting partition 3 to the inner wall of the unmanned boat body 2, when the vertical pole 5 is movably connected to the inside of the circular groove, the adjusting disc 7 can be prevented from passing through the inside of the circular groove, and will not affect the movement of the vertical pole 5 in the circular groove driven by the adjusting disc 7.
[0037] The above design enables the unmanned boat body 2 to carry the detection probe rod assembly 1 and perform detection work based on the existing driving and navigation technology. With the help of the adjusting disc 7, the top of the support partition 3 moves with the tilt of the unmanned boat body 2, so that one end of the first rod assembly 4 moves with the adjusting disc 7 through the universal joint 6, and the other end rotates around the support ball seat 12, so that the support ball seat 12 in the rotating state drives the second rod assembly 9 connected to it to rotate (around the support ball seat 12), and the second rod assembly 9 cooperates with the driven ball 13 and the counterweight seat 11 (with the help of the positioning ball groove 14 on the top of the counterweight seat 11, the driving ball 13 only rotates on the top of the counterweight seat 11 and can never move in the horizontal plane), pushing the counterweight seat 11 to move in the opposite direction of the adjusting disc 7 at the bottom inner wall of the unmanned boat body 2, and uses multiple universal wheels 10 to reduce friction resistance to adjust the center of gravity of the unmanned boat body 2 when the whole body is tilted, which is beneficial to ensure the stability of the unmanned boat body 2 during driving and improve its anti-interference ability.
[0038] It is worth noting that the adjustment disc 7, the universal joint 6 and the retractable first rod assembly 4 are used to control the retractable second rod assembly 9 through the support ball seat 12, and the movement of the counterweight seat 11 on the bottom inner wall of the unmanned boat body 2 is controlled based on the cooperation between the driving ball 13 and the positioning ball groove 14. It is necessary to keep the heavier side between the adjustment disc 7 and the counterweight seat 11 in coordination with the shorter side between the first rod assembly 4 and the second rod assembly 9 (refer to the length of the first rod assembly 4 and the second rod assembly 9 in the vertical state, that is, the initial length of the first rod assembly 4 and the second rod assembly 9) to achieve the function of applying a small force in a single direction to control the movement of the relatively heavier side in the opposite direction;
[0039] At the same time, the weight of the counterweight seat 11 and the adjusting disc 7 needs to be processed using different materials or different densities or different volumes according to actual conditions (the width, length, height and center of gravity of the bed, etc.), and the length ratio between the second rod assembly 9 and the first rod assembly 4 also needs to be designed with reference to the above-mentioned influencing factors, which is more flexible and practical.
[0040] Finally, it should be noted that the above embodiments are merely examples for the purpose of illustrating the present invention and are not intended to limit the embodiments. Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not necessary and impossible to provide an exhaustive list of all possible embodiments. However, any obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
