[0023] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention is further described below in conjunction with specific embodiments and drawings, but the following embodiments are only preferred embodiments of the present invention, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the present invention.

[0024] The specific embodiments of the present utility model are described below in conjunction with the accompanying drawings. Specific embodiment one:

[0026] Reference Figure 1-4 A high-efficiency nondestructive detection device for engineering structural defects includes a patrol control box 1 and a control main board 4. The bottom surface of the patrol control box 1 is connected with an electric-controlled universal wheel 2. The top surface of the electric-controlled universal wheel 2 is screwed to the bottom surface of the patrol control box 1. The cruise detector 12 is electrically connected to the ultrasonic detection head 14 and the laser ranging head 15. A display control panel 13 is provided on the surface of the cruise detector 12. The entire device is mainly driven by the electric-controlled universal wheel 2 to move the entire device to achieve walking on the surface of the ship. The equipment connected to the surface of the patrol control box 1 performs coverage detection on the surface of the ship. The signal transmission between various electric control devices is connected by the control main board 4, which is convenient for receiving the electric control signals of each detection and controlling the movement and cruise guidance of the entire device.

[0027] The whole device mainly detects defects on the surface of the ship through the connected cruise detector 12. The specific structure is that a guide motor 9 is embedded in the patrol control box 1, and the output shaft of the guide motor 9 is connected to a guide round table 10. A telescopic cylinder 11 is embedded in the guide round table 10. The movable end of the telescopic cylinder 11 is threadedly connected to a cruise detector 12. The two sides of the cruise detector 12 are respectively connected with an ultrasonic detection head and a laser ranging head 15. The patrol control box 1 is provided with a control main board 4. Ultrasonic waves are emitted by the ultrasonic probe head to scan the surface of the ship's shipboard. The cracks in the plate, profile and weld are detected by the characteristics of ultrasonic waves propagating in the material. The laser ranging probe The laser is used to measure the distance on the surface of the ship plate, which can be used to scan and detect the thickness and length of the ship plate. The laser ranging probe measures the size and shape changes of the hull structure to determine whether there is bending or twisting. The entire cruise detector 12 is synchronously moved and controlled with the ultrasonic detection head 14 and the laser ranging head 15. The guide motor 9 drives the guide table 10 to rotate, so that the guide angle of the cruise detector 12 can be controlled and adjusted, thereby realizing 360-degree scanning and detection of the entire device. The movable end of the telescopic cylinder 11 is extended and retracted to drive the cruise detector 12 to move up and down to adjust the height, thereby realizing contact scanning and detection of positions at different heights on the surface of the ship.

[0028] In order to facilitate the detection of the penetration position and penetration degree of the ship surface, storage bins 6 are provided on both sides of the inspection control box 1, and the storage bins 6 are filled with penetrant 7. Electric control nozzles 8 are horizontally penetrated on the surfaces of both sides of the inspection control box 1. The electric control nozzles 8 are electrically connected to the control main board 4. The ultrasonic detection head 14 detects the crack position of the ship. After the detection, the penetrant 7 is sprayed out through the electric control nozzle 8 to detect the penetration degree of the crack position. By observing the penetration amount of the penetrant 7, the degree of damage of the crack is judged. The more the penetrant 7 penetrates, the greater the degree of damage, thereby detecting the surface penetration position and penetration degree of the ship plate.

[0029] In order to facilitate the detection of ships below the inspection control box 1, an electric control connection slot 5 is provided on the front of the inspection control box 1, and an electric control connector 16 is provided on the back of the cruise detector 12, and the electric control connector 16 is clearance-matched with the electric control connection slot 5. The electric control connector 16 is clearance-matched with the electric control connection slot 5, so that the entire cruise detector 12 can be disassembled by rotating and retracting the movable end of the cylinder 11. The disassembled cruise detector 12 can be inserted into the electric control connection slot 5 on the front of the cruise control box through the electric control connector 16 on the back for connection, so that the cruise detector 12 is installed on the front of the inspection control box 1 to detect ships at a low position.

[0030] Other limiting structures of the entire device are that path cruise components 3 are provided on both sides of the front of the inspection control box 1, and the path cruise components 3 are electrically connected to the control main board 4. The entire device performs autonomous cruising and planning of the path through the path cruise components 3, so that the movement of the entire device can cover the entire surface of the ship. The bottom surface of the guide cone 10 is against the top surface of the inspection control box 1, and the vertical center axis of the guide motor 9 coincides with the vertical center line of the telescopic cylinder 11. The outer edges of the inspection control box 1 are all rounded. Specific embodiment 2:

[0032] Reference Figure 1-4 A battery structure is arranged inside the patrol control box 1 for powering the entire device. A wireless connection is adopted between the cruise detector 12 and the control main board 4 to facilitate the loading and unloading of the cruise detector 12 . Specific embodiment three:

[0034] Reference Figure 1-4 According to the content of the specific embodiment 1, the following technical content is further disclosed:

[0035] For the path cruise component 3, the internal infrared sensors, laser radars, cameras, etc. are used to detect environmental information, such as walls, obstacles, lines, etc. According to the information detected by the sensors, methods such as ant colony algorithms, genetic algorithms, particle swarm algorithms, etc. are used for path planning, and PID control, fuzzy control, neural network control, etc. are used to control their own movements. SLAM technology is a navigation and positioning technology commonly used in robot autonomous cruising. It allows the robot to complete the entire process of positioning, mapping, and path planning in an unknown environment. The implementation methods of SLAM technology include VSLAM, Wifi-SLAM, and LidarSLAM. The realization of the autonomous cruising function depends on the comprehensive application of technologies such as map construction, positioning and navigation, and sensor fusion. In addition, sensor detection, path planning, control algorithms, and SLAM technology also play an important role in the autonomous cruising process of the inspection control box 1. The combination and application of these technologies enable the inspection control box 1 to achieve autonomous cruising in a ship environment and perform various tasks.

[0036] For the ultrasonic detection head 14, the ultrasonic probe converts electrical energy into mechanical vibration through the transmitting element, thereby generating ultrasonic pulses. These pulses are generated in the piezoelectric sheet or quartz wafer of the probe, and propagate to the surface of the object to be detected, i.e., the ship, through the coupling agent of the probe. When the ultrasonic wave propagates in the surface material of the ship, it will be reflected, refracted and scattered when encountering the boundary of different media, such as the boundary between the steel plate and corrosion or cracks. The partially reflected ultrasonic wave returns to the receiving element on the probe, and the receiving element converts the ultrasonic wave into an electrical signal. These electrical signals are then processed by amplification and filtering, and transmitted to the ultrasonic equipment for further processing and analysis. The ultrasonic detection head processes and analyzes the received echo signals, and judges whether there are defects, cracks or corrosion on the surface of the ship according to the characteristics of the ultrasonic wave such as the propagation speed and absorption capacity in different media.

[0037] Specifically implement the detection of the following contents:

[0038] Surface defect detection: Through the reflection and scattering characteristics of ultrasound, it can detect whether there are cracks, corrosion and other defects on the surface of the ship. These defects will affect the structural strength and safety of the ship.

[0039] Material thickness measurement: The thickness of the ship's surface material can be measured by using the propagation speed and time difference of ultrasonic waves in the material. This is crucial for assessing the integrity and safety of the ship's structure.

[0040] Internal quality inspection: The ultrasonic inspection head 14 can also be used to inspect the quality of the internal structure of the ship, such as the quality of the welds, inclusions inside the steel plates, etc. These internal quality problems will also affect the safety and service life of the ship.

[0041] Regarding the laser ranging head 15, the laser ranging head 15 emits a laser beam. When the laser beam irradiates the surface or structure of the ship, part of the laser will be reflected back. The laser ranging head 15 will receive the reflected lasers. By measuring the time difference from the laser emission to the laser reception, combined with the speed constant of the laser propagation in the air, the distance between the laser ranging head 15 and the surface of the ship can be calculated. The received laser signal will undergo signal processing and calculation to obtain accurate distance data.

[0042] Specifically, it includes the following tests:

[0043] Hull size measurement: Laser ranging technology can accurately measure the length, width and distance of various parts of the ship's hull, helping ship managers to accurately understand the size of the ship.

[0044] Channel depth measurement: Through the reflection of laser beams from the water surface, laser rangefinders can measure the water depth and determine whether the channel has enough water depth for ships to navigate.

[0045] Improve measurement accuracy: Combined with 3D technology, the laser distance measuring head 15 can achieve higher-precision ship measurement. By building a 3D model of the ship, laser distance measurement technology can ensure measurement accuracy at the sub-millimeter level, promoting the development of the shipbuilding industry.

[0046] Special measurement requirements: For some special parts or structures of the ship, such as mast winding, stern tube concentricity, etc., the laser rangefinder head 15 can also provide accurate measurement solutions. These measurements usually involve the use of specific laser transmitters and receivers, combined with professional measurement software for processing.

[0047] The cruise detector 12 is mainly used for connecting the ultrasonic detection head 14 and the laser ranging head 15 and displaying the detection signals.

[0048] In summary:

[0049] 1. The bottom of the inspection control box 1 is used to cruise the surface of the ship through the electric universal wheel 2. The cruise detector 12 connected by the guide round table 10 cooperates with the ultrasonic detection head 14 and the laser ranging head 15 to detect and display the thickness, defects and internal foreign objects of the ship surface. Through angle rotation and height adjustment, it can meet the coverage detection of various positions on the ship surface and realize the efficient non-destructive detection of the ship surface plate. It has a high degree of automation and does not require manual intervention. It integrates autonomous cruising and autonomous detection in one movement, with a wide coverage range and high detection efficiency.

[0050] 2. The inspection control box 1 is used to detect defects on the ship surface through the ultrasonic detection head 14 and the laser ranging head 15 on the top, and a storage bin 6 with a penetrant 7 is set inside, and the penetrant 7 is applied on the ship surface in cooperation with the electric control nozzle 8 to detect whether the cracks on the ship surface are leaking, thereby realizing contact detection of cracks on the ship surface, and facilitating timely detection of the location and degree of cracks on the ship.
