As shown in fig. 1A and 1B, a schematic structural diagram of an integrated pipeline ultrasonic detection device for underwater operation in an embodiment of the present utility model is shown; fig. 1A shows a circuit module structure diagram in an electronic cabin of the integrated ultrasonic detection device, fig. 1B shows an external schematic diagram of the integrated ultrasonic detection device, and fig. 1C shows a cross-sectional schematic diagram of the integrated ultrasonic detection device.

Taking the structure of fig. 1C as an example, pointing according to the arrow from top to bottom, the uppermost arrow points to the headstock 17; the following arrow points to the depth measurement module 16; the following arrow points to the cup 18; the next arrow points to the battery pack 15; the next arrow points to a detection electronic package 19 (the detection electronic package is provided with circuit modules such as an ultrasonic signal excitation and receiving module 12, a data acquisition and processing module 13, a data storage module 14 and the like); the next arrow points to the ultrasonic probe set 11; the lowermost arrow points to the impact head 110.

In this embodiment, the lower operation integrated ultrasonic detection device includes a seal housing; an electronic cabin is arranged in the sealed shell; the structure of the electronic cabin is shown in fig. 1C, and the electronic cabin is provided with: the ultrasonic probe set 11 and the detection electronics comprise 19 (an ultrasonic signal excitation and receiving module 12, a data acquisition and processing module 13 and a data storage module 14 are arranged in a detection electronics package), a battery set 15 and a depth measurement module 16. The ultrasonic probe set 11 is electrically connected with the ultrasonic signal excitation and receiving module 12; the ultrasonic signal excitation and receiving module 12 is electrically connected with the data acquisition and processing module 13; the battery pack 15, the ultrasonic signal excitation and receiving module 12 and the data acquisition and processing module 13; the depth measurement module 16 is electrically connected to the data acquisition and processing module 13.

The ultrasonic probe set 11 includes one or more ultrasonic probes for scanning ultrasonic signals of an underwater object to be measured. An ultrasonic probe is a device for transmitting and receiving ultrasonic waves in the ultrasonic detection process, wherein the performance of the probe directly influences the characteristics of the ultrasonic waves and influences the detection performance of the ultrasonic waves; the probe used in ultrasonic detection is a transducer which utilizes the piezoelectric effect of materials to realize electric energy and acoustic energy conversion. The key component in the probe is the wafer, which is a single or multi-crystalline sheet with piezoelectric effect, which is used to convert electrical and acoustic energy into each other. Specifically, the ultrasonic probe may be a straight probe, an inclined probe, a probe with curvature, a focusing probe, a surface wave probe, or the like, and the present embodiment is not limited thereto.

The ultrasonic signal excitation and reception module 12 is configured to acquire the ultrasonic signal and convert the ultrasonic signal into ultrasonic detection data. Specifically, the ultrasonic signal excitation and receiving module converts the received ultrasonic signal into other energy signals (usually electrical signals) to form ultrasonic detection data. In general, ultrasonic waves are mechanical waves with vibration frequencies higher than 20kHz, and have the characteristics of high frequency, short wavelength, small diffraction phenomenon, particularly good directivity, capability of being used as rays to directionally propagate, and the like, and have great penetrating power on liquids and solids, particularly in solids opaque to sunlight. The ultrasonic waves can be obviously reflected to form a reflected echo when encountering impurities or interfaces, and the Doppler effect can be generated when the ultrasonic waves collide with a living body.

The data acquisition and processing module 13 is configured to acquire the ultrasonic detection data and perform analog-to-digital conversion, and mainly convert the acquired ultrasonic analog signal into a digital signal that can be identified by a computer through a sensor, a transducer, and the like. Further, the data acquisition processing system is typically comprised of sensors, amplification circuits, filters, multiple analog switches, sample/holders, D/a converters, computer I/O interfaces, and timing and control logic.

The battery pack 15 is integrated with the ultrasonic signal excitation and receiving module 12 and the data acquisition and processing module 13 to supply power to the ultrasonic signal excitation and receiving module 12 and the data acquisition and processing module 13. It should be noted that, according to the technical scheme that the ultrasonic signal excitation and receiving module, the data acquisition and processing module and the battery pack are integrated together, the internal self-power supply of the underwater device is realized, so that ultrasonic detection can be realized without relying on an operation desk and a special cable on the ground for power supply and control, and the convenience of using the device is greatly improved.

The data storage module 14 is used for storing ultrasonic detection data. The data storage module includes, but is not limited to, read-only memory, random-access memory, EEPROM, CD-ROM or other optical disk storage, magnetic disk storage or other magnetic storage devices, flash memory, U-disk, removable hard disk, or any other medium that can be used to store desired program code in the form of instructions or data structures and that can be accessed by a computer, and since the storage medium and storage technology itself are well-known, it is not repeated here.

In some examples, a power-activated watertight connector (not shown) is provided external to the integrated ultrasonic detection device; the power-on watertight connector is electrically connected with the battery pack 15; the power-on watertight connector is also provided with a battery-on cap; after the battery starting cap is arranged on the power supply starting watertight connector, the battery pack automatically powers on the ultrasonic signal excitation and receiving module; after the battery-starting cap is removed, the battery pack is de-energized, in which case a charging plug connector may be connected to power the battery pack 15.

It will be appreciated that power-activated watertight connectors are known in the industry as subsea connectors or subsea connectors for effecting subsea power connections, and in the field of marine research and development, power-activated watertight connectors are the most commonly used electromechanical components, also one of the most used components.

In some examples, the object under water comprises an underwater or underground vertical pipeline; the integrated ultrasonic detection device is hung in the underwater or underground vertical pipeline and is used for detecting the wall thickness of the pipeline through ultrasonic waves and further detecting the corrosion degree of the pipeline.

Further, in order to more comprehensively understand the wall thickness condition in the whole circumferential direction of the underwater vertical pipeline, each ultrasonic probe in the ultrasonic probe group in the embodiment of the utility model is uniformly distributed along the circumferential direction of the underwater vertical pipeline so as to perform ultrasonic scanning on the pipe wall in the whole circumferential direction of the underwater vertical pipeline.

In some examples, the integrated ultrasonic detection device further includes a pair of bowl-shaped elastic cups 18 respectively disposed at the upper and lower ends of the ultrasonic detection device, for maintaining the integrated ultrasonic detection device in a centered state at all times inside the pipe. Further, the bowl-shaped elastic leather cup can be made of rubber and other materials, and is sleeved on the upper end and the lower end of the ultrasonic detection device.

In some examples, the integrated ultrasonic detection device further includes a depth measurement module 16; the depth measurement module 16 may optionally use a water depth sensor to collect current underwater depth data by detecting a water pressure signal. The water depth sensor measures the underwater depth through the association relation between the water pressure and the water depth, and generally, the water pressure of 1mpa is about 100 meters, and the like. By using the novel depth measuring method, the encoder used in the prior art on the ground is abandoned, the volume of the integrated ultrasonic detection device is greatly reduced, the interaction with the ground is not needed, and even a common general winch can carry the device down to put into water to finish detection.

Further, the depth measurement module 16 is electrically connected to the data storage module 14, and stores the underwater depth data in the data storage module 14. Thus, the ultrasonic signal excitation and receiving module 12 detects the pipe wall at fixed time intervals to obtain ultrasonic detection data, and records the depth data of the underwater depth sensor, and the ultrasonic detection data and the underwater depth data can be integrated and stored in the data storage module 14.

It should be noted that, in the existing ultrasonic detection device, the ultrasonic detection data is transmitted back to the shore in real time in the detection process, which brings about a lot of problems, such as interruption or missing of data transmission caused by poor underwater communication quality, and further such as cost increase and overlong transmission line caused by using wired transmission.

In some examples, a hoist lifting ring (not shown) is arranged above the integrated ultrasonic detection device, and the hoist lifting ring is used for driving the ultrasonic detection device to lift after being connected with the traction hoist device. For example, a traction device such as a winch can be used, and the ultrasonic detection device can be lifted or lowered by traction after the lifting rope is inserted into the lifting ring.

In some examples, the integrated ultrasonic detection device further includes a pair of supporting wheel structures 111 (as shown in fig. 1D) respectively disposed at the upper and lower ends of the device for supporting and rolling the wheels.

In summary, the utility model provides an integrated pipeline ultrasonic detection device for underwater operation, which aims to integrate an electronic probe and a battery into a whole, and complete detection without relying on an operation table on the ground and a special cable for power supply and control. Meanwhile, the detection device also uses a new sounding method, omits an original encoder on the ground, and realizes sounding by a mode of sounding water pressure so as to replace a sounding sensor. The integrated ultrasonic detection device not only greatly reduces the volume, but also does not need to interact with the ground, so that the ultrasonic detection device can be carried by using a common winch to finish the detection when the device is used for launching. In addition, the detection data are stored in a data storage module in the detection device, and the data are downloaded through a special data download interface for subsequent analysis after the detection is finished. The ultrasonic detection device is convenient to operate, and is convenient to carry because the ultrasonic detection device does not depend on special ground control equipment such as a detection vehicle and a winch, and the detection cost is greatly reduced. The utility model effectively overcomes various defects in the prior art and has high industrial utilization value.

The above embodiments are merely illustrative of the principles of the present utility model and its effectiveness, and are not intended to limit the utility model. Modifications and variations may be made to the above-described embodiments by those skilled in the art without departing from the spirit and scope of the utility model.
