[0031] Furthermore, the terms "first", "second", etc. are used only for descriptive purposes and should not be construed as indicating or implying relative importance or an indicated number of technical features. Thus, features defined with "first", "second" can explicitly or implicitly include at least one of the features.
[0032] Referring to Figures 1 to 2 The utility model discloses an auxiliary obstacle cleaning device that cooperates with underwater pipeline detection, including unmanned underwater vehicle 100 and the illumination system 17, camera system 12 that are carried on unmanned underwater vehicle, camera system 12 cooperates with illumination system 17 and gathers underwater pipeline image.In addition, the unmanned underwater vehicle 100 is connected with cable 14, and the unmanned underwater vehicle is installed with the obstacle removing mechanical arm 13 and is equipped with anchor 16, the obstacle removing mechanical arm 13 is used for removing the first object attached on underwater pipeline, and the anchor 16 is used for hooking the second object attached on underwater pipeline, the cable is operated and pulls the unmanned underwater vehicle to move to the shore, and the second object is dragged back to the shore by the anchor.
[0033] It can be understood that the cable is normally used for power supply and information transmission, and the unmanned underwater vehicle needs to meet the corresponding strength requirement.
[0034] Among them, the anchor 16 is connected with the take-up and pay-off rope, and the take-up and pay-off rope is connected with the winch 15, so that the winch 15 controls the taking-up and paying-off of the anchor, and the anchor can be taken up and paid out. The winch can be installed with a force sensor to detect the force of the second object on the anchor, in combination with the camera system 12, to determine whether the second object needs to be dragged to the shore (the second object is large enough, or other conditions that the mechanical arm is difficult to remove). The shell of the unmanned underwater vehicle is provided with a recess for accommodating the anchor. When not in use, the anchor can be accommodated to avoid affecting the normal operation of the unmanned underwater vehicle 100.
[0035] In the embodiment, the free end of the obstacle removing mechanical arm 13 is provided with a gripper 131. The obstacle removing mechanical arm is provided with a multi-degree-of-freedom joint 132. The obstacle removing mechanical arm realizes rotation and extension of the gripper 131 through the multi-degree-of-freedom joint 132.
[0036] When the UUV runs along the extension direction of the underwater pipeline, the camera system cooperates with the lighting system to collect images of the underwater pipeline. According to the collected images of the underwater pipeline, some silt and waterweeds attached to the underwater pipeline, which are defined as first objects herein, can be removed by the obstacle-removing mechanical arm, but some larger objects, such as larger branches, which are defined as second objects herein, are difficult to be removed by the obstacle-removing mechanical arm. The anchor is used to hook the second objects attached to the underwater pipeline, and the cable is operated to pull the UUV to move towards the shore, and the second objects are dragged back to the shore by the anchor, thus solving the problem that the conventional obstacle-removing mechanical arm is difficult to clean some larger objects attached to the pipeline in the prior art.
[0037] As shown in Figure 3 , the gripper 131 can be closed and clamped to an object. The obstacle-removing mechanical arm realizes rotation and extension of the gripper through a multi-degree-of-freedom joint. After the gripper is clamped, the object can be pulled off by rotation, and the object can also be separated from the pipeline by pulling it backward. Figure 4 As shown in , the gripper 131 can also be opened, and then pushed along the surface of the pipeline to remove the silt on the surface of the pipeline.
[0038] In addition, the obstacle-removing mechanical arm can be stretched and folded through the multi-degree-of-freedom joint 132, which is convenient for transportation.
[0039] The specific structure of the UUV can be the prior art, which includes a sealed shell, a buoyancy chamber provided in the sealed shell, and a propulsion system 11 for moving the UUV underwater. The buoyancy chamber provides buoyancy, and the propulsion system provides a driving force, so that the UUV can run underwater, including some actions that the existing UUV can complete, such as up and down, forward, transverse, rotation, etc. The shell is a cylindrical structure.
[0040] It can be understood that the UUV is also provided with an IMU module for navigation and control, and is also provided with a power system. The propulsion system includes a vertical propeller and a horizontal propeller, so that the UUV can flexibly dive underwater. The power system includes a battery and a motor, which are provided in a waterproof shell. The battery supplies power to the motor, and the motor can drive the propulsion system. The navigation and propulsion of the UUV belong to the prior art, and will not be described here.
[0041] In this embodiment, the camera system 12 is provided with a spherical camera, and the obstacle-removing mechanical arm 13 is provided with two, which are arranged side by side on the front side of the spherical camera. The cooperation of the two obstacle-removing mechanical arms can improve the obstacle-removing efficiency. The spherical camera can collect images at multiple angles, which is beneficial to the obstacle-removing mechanical arm to clean the objects on the pipeline according to the collected images.
[0042] Preferably, the anchor 16 is located in the middle of the unmanned underwater vehicle and behind the spherical camera.
[0043] It can be understood that the utility model is matched with the detection of underwater pipeline, so the unmanned underwater vehicle can carry the detection system. The detection system comprises a receiver and a sonar device. When the detection is carried out, the electromagnetic signal transmitter applies a set current signal to the pipeline, the current signal extends to the far field along the pipeline, and an electromagnetic field is formed around the pipeline. The receiver is used for detecting the current intensity in the pipeline and detecting the pipeline burial depth. The sonar device is used for detecting the distance from the water bottom.
[0044] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited to this. Those skilled in the art should understand that the utility model includes but is not limited to the contents described in the drawings and the above specific implementation. Any modification not deviating from the function and structural principle of the utility model will be included in the scope of claims.
