[0027] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0028] As shown in Figures 1-6 :

[0029] A pile foundation underwater scour monitoring device, including underwater monitoring robot 1, underwater monitoring robot 1's monitoring area is fixed with two symmetrical setting fitting pieces 3 relative to underwater monitoring robot 1;

[0030] Fitting piece 3 is fixedly connected at the outer surface of underwater monitoring robot 1 by support bracket 2.

[0031] In this embodiment, the pile foundation will inevitably be damaged during long-term underwater use, and regular monitoring and identification of the pile foundation are necessary. The traditional pile foundation detection method is generally to send divers to work underwater to monitor and identify the pile foundation regularly. However, this method has certain safety risks. Therefore, various underwater monitoring robots 1 have appeared on the market to replace manual monitoring and identification work, and most of them operate the underwater monitoring robot 1 in a remote control manner. The traditional underwater monitoring robot 1 has a light supplementing picture shooting function, a sonar imaging function, a distance measuring function, a laser positioning function, and an infrared imaging function, and can transmit data in real time.

[0032] However, the structural arrangement of the pile foundation can easily cause water flow disorder near the pile foundation, resulting in unstable hovering position of the underwater monitoring robot 1 under water, and obvious disordered shaking, which seriously affects the monitoring and identification work. Some underwater monitoring robots 1 have an underwater position self-locking function, which can improve stability, but the effect is not good and the cost is high. The present scheme installs a fitting part 3 on the underwater monitoring robot 1 through a supporting bracket 2. When the underwater monitoring robot 1 is working, the underwater monitoring robot 1 is moved to the target area, the fitting part 3 is fitted with the surface of the pile foundation, and then the underwater monitoring robot 1 is driven to continuously provide a vertical thrust towards the pile foundation, thereby driving the fitting part 3 to tightly fit the surface of the pile foundation, so as to form a stable state and avoid water flow disorder causing shaking of the underwater monitoring robot 1. That is, by driving the underwater monitoring robot 1 to provide a thrust, the fitting part 3 is tightly fitted with the surface of the pile foundation. At this time, the underwater monitoring robot 1, the fitting part 3, and the pile foundation form a relatively stable system. In this system, the water flow force, the thrust of the robot, and the friction between the fitting part 3 and the pile foundation can reach a state of balance, so that the robot can maintain a stable position under water. At this time, only a thrust in one direction needs to be provided by the underwater monitoring robot 1, without the need for constant adjustment under dynamic conditions in the traditional way. The traditional method can only reduce the amplitude of shaking, because the adjustment process is dynamic and cannot completely reduce the shaking of the underwater monitoring robot 1. The stability problem is solved by simple mechanical structure and principle, which has certain advantages in cost control and good economic efficiency. After the position of the underwater monitoring robot 1 is stabilized, the monitoring work of the pile foundation can be carried out, which is convenient to operate and improves the efficiency and reduces the error of monitoring.

[0033] Further;

[0034] In an optional embodiment, the fitting part 3 is in a strip shape. Since the pile foundation is generally a regular structure, most of the pile foundations have a runway-shaped, rectangular or circular cross section, and the outer surface is mainly flat or arc-shaped. Therefore, the fitting part 3 is arranged in a strip shape, which can better fit the fitting part 3 with the surface of the pile foundation and improve the stability when the fitting part 3 is fitted with the surface of the pile foundation.

[0035] In an optional embodiment, the fitting part 3 comprises a fitting plate 301, one end of the fitting plate 301 is fixedly connected with the support bracket 2, and the edge of the fitting plate 301 is directly in contact with the surface of the pile foundation, which can improve the stability during contact while reducing the contact area, and at the same time, when the underwater monitoring robot 1 moves, the fitting plate 301 can reduce the resistance of the water flow as much as possible.

[0036] In an optional embodiment, the edge of the fitting plate 301 is provided with a wavy edge 302, which can reduce the contact area between the fitting plate 301 and the surface of the pile foundation, so that when there are small protruding particles on the surface of the pile foundation, there is a greater probability that the protrusions will be located in the gap between the wavy edge 302 and the surface of the pile foundation. On the other hand, since the contact area between the two is reduced, when the underwater monitoring robot 1 moves along the surface of the pile foundation, especially along the extension direction of the fitting plate 301, the resistance is smaller, thereby monitoring other parts of the surface of the pile foundation under the condition that the underwater monitoring robot 1 moves stably.

[0037] The thrust direction of the underwater monitoring robot 1 is divided into two parts, one part is to apply thrust to the underwater monitoring robot 1 in a direction perpendicular to the surface of the pile foundation, and the other part is to apply thrust in the extension direction of the fitting plate 301.

[0038] In an optional embodiment, the edge of the fitting plate 301 is rotatably connected with a rubber ring 304, the rubber ring 304 is provided with a groove for accommodating the fitting plate 301, and the rubber ring 304 should have a certain elasticity, so as to facilitate the rubber ring 304 to be sleeved on the edge of the fitting plate 301, and at the same time, the fitting plate 301 and the rubber ring 304 can be prevented from being separated. When the underwater monitoring robot 1 moves along the surface of the pile foundation, the relative rotation between the rubber ring 304 and the fitting plate 301 can make the underwater monitoring robot 1 move more easily and stably.

[0039] In an optional embodiment, the outer surface of both ends of the fitting plate 301 is fixedly connected with a retaining bracket 305, the inner side of the end of the retaining bracket 305 is rotatably connected with a rotating wheel 306, and the two rotating wheels 306 in the same fitting part 3 are in the same plane with the fitting plate 301. The edges of the fitting plate 301 and the two rotating wheels 306 are rotatably connected with the inner side of a rubber ring 304, and through the design of the rotating wheel 306, the rotation of the rubber ring 304 is more convenient.

[0040] In an optional embodiment, one end of the fitting plate 301 is fixedly connected with a waterproof motor 3010 inside, the main shaft of the waterproof motor 3010 is fixedly connected with a driving pulley 309 outside, the outer surface of the rotating wheel 306 away from the retaining bracket 305 is fixedly connected with a fixed shaft 307, the outer side of the fixed shaft 307 is fixedly connected with a driven pulley 308, and the outer sides of the two driven pulleys 308 and the driving pulley 309 are jointly meshed with a transmission belt 3011.

[0041] In this embodiment, the driving rotation of the waterproof motor 3010 drives the driving pulley 309 to rotate, the driving pulley 309 drives the driven pulley 308 to rotate through the transmission belt 3011, the driven pulley 308 drives the fixed shaft 307 to rotate and thus drives the rotating wheel 306 to rotate, the rotating wheel 306 can drive the rubber ring 304 to rotate, so that the underwater monitoring robot 1 moves along the pile foundation surface by the driving rotation of the rubber ring 304, and since the rubber ring 304 is provided with two, the underwater monitoring robot 1 can also control the turning of the pile foundation surface, which is similar to the turning mode of the tank track, and under the condition that the rubber ring 304 can be driven to rotate, the underwater monitoring robot 1 only needs to exert a thrust force perpendicular to the pile foundation surface; and by providing the wave edge 302, the sliding resistance between the rubber ring 304 and the fitting plate 301 can be further reduced.

[0042] In an optional embodiment, the outer surface of the fitting plate 301 is rotatably connected with a plurality of extrusion wheels 3012, and the extrusion wheels 3012 are used to extrude the transmission belt 3011 to increase the meshing area of the driving pulley 309 and the transmission belt 3011. Since the transmission belt 3011 is arranged in a manner that the contact area between the transmission belt 3011 and the driving pulley 309 is small, in order to avoid slipping between the driving pulley 309 and the transmission belt 3011, the transmission belt 3011 is extruded by the extrusion wheels 3012, so that the transmission belt 3011 and the driving pulley 309 have a larger meshing area, thereby avoiding the occurrence of slipping.

[0043] In an optional embodiment, the opposite outer surfaces of the two fitting plates 301 are fixedly connected with a contrast ruler 303, the surface of the contrast ruler 303 is marked with a scale, and the video transmission picture of the underwater monitoring robot 1 covers the contrast ruler 303, so that the control personnel can more intuitively observe the specific size of the hidden danger point of the pile foundation surface.

[0044] In an optional embodiment, the outer surface of the fitting plate 301 is fixedly connected with a reinforcing rib 3013, one end of the reinforcing rib 3013 is fixedly connected with the outer surface of the waterproof motor 3010, since the fitting plate 301 is thin, it is inconvenient to directly fix the waterproof motor 3010, therefore, the setting of the reinforcing rib 3013 can facilitate the fixation of the waterproof motor 3010, and can increase the structural strength of the fitting plate 301.

[0045] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application have been described in detail, for those skilled in the art, it still can be modified, or the equivalent replacement of part of the technical features of the technical solutions recorded in the foregoing embodiments. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included within the scope of the present application.
