Description

TECHNICAL FIELD

[0001] The application relates to the technical field of ship weld joint detection, and in particular to a ship underwater weld joint quality detection device. BACKGROUND

[0002] Ship weld joint quality detection is a key link for guaranteeing the structural integrity and navigation safety of a ship. As a core joint of ship steel plate connection, the quality of a weld joint directly affects the strength and sealing property of a ship body. Traditional manual inspection has problems such as low efficiency, high risk, frequent missed detection and misdiagnosis, and cannot meet the high requirements of modern shipping industry on safety and economy.

[0003] For the detection of a ship weld joint, a quality detection device based on a ship weld joint is disclosed in Chinese Patent No. CN117288771B, which effectively solves the problem that it is not easy to protect the camera when the camera is inserted into a relatively narrow position in the ship body. The device comprises a detector, the top end of the detector is provided with a swan neck pipe, the swan neck pipe is arranged in an N-shaped form, one end of the swan neck pipe is provided with an end frame, a detection control assembly is arranged on the end frame, a pipe limiting assembly is arranged on one side of the detector close to the end frame, a clamping fixing assembly is arranged at the bottom end of the detector, and a display is arranged on the front face of the detector. The detection control assembly comprises a transmitting end arranged at the top end of the end frame. When the camera body needs to enter the gap position to take pictures of the weld joint, the fixed cover and the two movable covers form a protective cover to protect the camera body, thereby protecting the camera body when passing through the gap position.

Since the existing technology does not involve waterproof measures, it is impossible to detect the weld joint in the underwater environment, and it is also impossible to meet the detection requirements in the underwater or humid environment, which may cause damage to the camera body and the circuit, affecting the detection efficiency and accuracy.

Embodiment one:

[0034] As shown in the figure, Figure 1 With Figure 6 The ship underwater welding seam quality detection device of the application, comprising a detector 100, a gooseneck pipe 110, a pipe body limiting assembly 120, an end frame 130, a clamping and fixing assembly 140 and a detection unit, the top end of the detector 100 is provided with a receiving end 102, the detection unit is fixed below the end frame 130, including a camera body 150, a light lamp 160 and a protection shell 200;

[0037] The pipe body limiting assembly 120 is used for limiting and fixing the gooseneck pipe 110, including a fixed plate, a limiting groove, a limiting plate, an end plate and a fourth spring, mainly limiting and fixing the gooseneck pipe 110 through the limiting plate and the limiting groove, preventing the gooseneck pipe 110 from shaking during detection, which affects the detection; the clamping and fixing assembly 140 is used for controlling the coordinated operation of each part of the detection platform, including a bottom swivel seat, a clamping ring, a bottom plate, an air bag and an air nozzle, mainly realizing clamping and fixing through inflation and expansion of the air bag; the camera body 150 is provided with a built-in battery and is communicated with the transmitting end 101 through a circuit, which is used for transmitting detection signals; they are all prior art and will not be described here.

[0038] In actual operation, the steps of the embodiment are as follows: first, during use, the device is fixed on the pipeline near the weld through the clamping and fixing assembly 140, at this time, the protective shell 200 is in a contracted state, and the camera body 150 is tightly wrapped in the inner layer capsule 220; then, the position of the camera body 150 is adjusted through the swan neck pipe 110 according to the detection position, and the swan neck pipe 110 is limited and fixed through the pipe body limiting assembly 120, and the position of the camera body 150 is positioned; finally, the protective shell 200 is inflated by the miniature external air pump, the protective shell 200 starts to expand to protect and waterproof the camera body 150, the camera body 150 starts to shoot the weld image, the illuminating lamp 160 provides illumination, the detection signal is emitted through the emitting end 101, the receiving end 102 receives and processes the signal, and the image is displayed on the display of the detector 100; after the detection is completed, the gas in the inner layer capsule 220 is discharged through the miniature air pump, the protective shell 200 gradually contracts to the initial state, the camera body 150 and the swan neck pipe 110 are restored to the original state, and the whole device is taken down through the clamping and fixing assembly 140.

[0039] The technical solutions in the above embodiment have at least the following technical effects or advantages:

[0040] The protective shell 200 with the hollow capsule structure can form a tight sealing structure after inflation, effectively isolates moisture and humidity, protects the camera body 150 and the internal circuit from the influence of underwater or high-humidity environment, effectively prevents the invasion of moisture and dust, ensures the durability of the sealing effect, further enhances the waterproof performance, helps to prolong the service life of the equipment and reduce the maintenance cost; the expansion and contraction of the protective shell 200 can be easily realized by controlling the external air pump, the flexibility of the detection device is improved, which can adapt to the weld detection requirements of different shapes and sizes, and the detection efficiency and accuracy are improved.

[0041] At the same time, the silica gel material has good elasticity, and when the protective shell 200 is impacted by external force, it can absorb and disperse the impact force through its own deformation to provide effective buffer protection for the camera body 150; effectively solves the technical problems of limited detection range, high risk of equipment damage, reduced detection efficiency and reduced detection accuracy in the prior art, and achieves the technical effects of expanded detection range, reduced risk of equipment damage, improved detection efficiency and improved detection accuracy. Embodiment two:

[0042] When detecting the weld submerged in water (such as the weld of the ship bottom), the water flow has an influence on the detection result because the water body is always in a flowing state. The water flow disturbs the suspended matter and light in the water, resulting in blurred or deformed images captured by the camera, which affects the accurate judgment of the weld quality by the detection personnel. In order to improve the detection accuracy, the present application proposes the following technical solutions in view of the above technical problems, specifically as follows:

[0043] As shown in Figures 1 to 4 The protective shell 200 is divided into two cover shells 210, which are hemispherical capsule structures and are respectively located on the left and right sides of the camera body 150, for balancing the stability of the camera body 150 during the underwater detection process.

[0044] The cover shell 210 includes an inner layer capsule 220 and an outer layer capsule 230; the inner layer capsule 220 is wrapped on the outer side of the camera body 150; and the outer layer capsule 230 is fixed on the outer side of the inner layer capsule 220 and is a conical sector structure.

[0045] A plurality of reinforcing ribs 231 are uniformly arranged on the inner side of the outer layer capsule 230 along the circumferential direction, for enhancing the overall structural strength of the protective shell 200; the reinforcing rib 231 is a strip-shaped capsule structure and is communicated with the inside of the inner layer capsule 220, for driving the outer layer capsule 230 to expand outward and form a hollow circular truncated cone structure when the inner layer capsule 220 inflates and expands.

[0046] After the outer layer capsule 230 is expanded, the weld is shielded from the external water body, and after the inner layer capsule 220 inflates and expands, an enclosed space is formed between the outer layer capsule 230 and the weld and the water body, for ensuring the stability of the internal water quality during detection.

[0047] The present application sets the reinforcing rib 231, so that when the inner layer capsule 220 inflates and expands, the outer layer capsule 230 expands under the guidance of the reinforcing rib 231 and forms a circular truncated cone structure, which shields the weld and the water body outside the weld to form an enclosed space, to a certain extent, inhibits the disturbance of the water flow, reduces the direct impact and disturbance of water molecules on the surface of the weld, helps to keep the surface of the weld relatively stable, and improves the clarity and accuracy of image acquisition; at the same time, the negative pressure effect can effectively reduce the penetration of water molecules, enhance the overall sealing performance of the protective shell 200, and ensure the dryness and safety of the internal camera body 150 and electronic equipment.

[0048] The conical sector structure of the outer layer capsule 230 helps to form a dynamic balance in the water flow, reduces the structural shaking caused by the change of water flow direction, and further improves the stability of detection; the plurality of reinforcing ribs 231 not only enhance the overall structural strength of the protective shell 200, but also can disperse stress when inflating and expanding, improve the pressure resistance of the protective shell 200, and make it able to resist the complex stress changes of the underwater environment. Embodiment three:

[0049] In view of the fact that the water quality in the area where the detected weld is located may be relatively turbid, impurities in the water quality surrounding the weld may interfere with the detection process, in order to improve the detection efficiency and further improve the detection accuracy, the present application proposes the following technical solutions to solve the above technical problems, specifically:

[0050] As shown in Figures 5 to 7 The inner layer capsule 220 is provided with three layers, which are sequentially divided into inflation film one 221, inflation film two 222 and inflation film three 223 from inside to outside, and the inflation film one 221 and the inflation film two 222, the inflation film two 222 and the inflation film three 223 constitute inflation chambers, and multiple inflation chambers sequentially expand to form a multi-stage inflation structure, and each inflation chamber is controlled to expand step by step through an independent air path. When the pressure of the air path reaches a certain value, the secondary air path can be opened to expand step by step.

[0051] The thickness of the inflation film one 221, the inflation film two 222 and the inflation film three 223 increases from inside to outside.

[0052] The outer side of the outer layer capsule 230 is fixed with a one-way valve one 170 and a one-way valve two 180 in a detachable manner, which is used to replace the water body wrapped inside the outer layer capsule 230 under the inflation of the inner layer capsule 220.

[0053] The one-way valve one 170 is provided with a micro filter inside for controlling the clean water flow; the one-way valve two 180 is used to control the internal water flow, and cooperates with the one-way valve one 170 to complete the water body replacement.

[0054] The present application divides the inner layer capsule 220 into three layers, and the inflation film one 221, the inflation film two 222 and the inflation film three 223 can expand step by step to form a pressure gradient, and match the opening pressure of the one-way valve one 170 and the one-way valve two 180, to ensure that the water body replacement process is stable and efficient; the one-way valve one 170 is provided to control the clean water body to enter, and the micro filter is provided inside to effectively intercept impurities; the one-way valve two 180 controls the turbid water body to flow out, to ensure smooth drainage, realizes the bidirectional control of the water body, and speeds up the replacement process; through the optimization of the structure design of the inner layer capsule 220 and the outer layer capsule 230, the multi-stage inflation structure and the independent air path design make the device can adapt to the detection needs under different environmental and water body conditions, whether it is a deep water environment or a complex water body condition, the device can maintain stable performance, and the durability and service life of the device are improved. Embodiment four:

[0055] Considering that in a complex water body (such as a river estuary or a coastal salinity gradient area), the inner bag 220 will generate buoyancy inside the water body in the inflated state, so that the device is easy to tilt due to unbalanced buoyancy, in order to make the device more stable in the water body detection, to adapt to different detection environments, the present application proposes the following technical solutions to solve the above technical problems, specifically:

[0056] As shown in Figure 7 and Figure 8 , the outer side of the outer bag 230 is uniformly provided with a plurality of closed openings 240 along the circumference, the closed openings 240 correspond to the reinforcing ribs 231 one by one, and the closed openings 240 are in communication with the inside of the reinforcing ribs 231; the inside of the reinforcing rib 231 is provided with a plurality of metal balls 232, which are loaded into the corresponding reinforcing rib 231 through the closed opening 240, and the metal balls 232 of different weights are used to adjust the buoyancy state of the protective shell 200 in water.

[0057] Because the detection environment may be the sea, a lake or a river, the water density is different, and different underwater environments have different water density and buoyancy characteristics. The inner bag 220 will generate buoyancy inside the water body in the inflated state, and appropriate buoyancy is crucial for underwater detection. If the buoyancy is too large, the device may float on the water surface and cannot contact the bottom weld for detection; if the buoyancy is too small, the device may sink too fast and it is difficult to control the detection position and angle.

[0058] The present application precisely controls the buoyancy state of the detection device in water by artificially adjusting the weight of the metal balls 232, so that it can maintain a stable suspended or sinking state in water bodies of different densities, reducing the risk of overturning or losing control due to uneven buoyancy, which is conducive to the stable displacement of water quality, improves the stability during detection, so that the detection device can adapt to a wider range of underwater detection scenarios, improves its versatility and applicability, thereby improving the detection efficiency and effect.

[0059] It should be noted that in the above embodiments, the description of each embodiment has its own emphasis, and the parts not described in detail in a certain embodiment can be referred to the related description of other embodiments.

[0060] Obviously, those skilled in the art can make various modifications and variations to the present application without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present application fall within the scope of the claims of the present application and their equivalents, the present application also intends to include these modifications and variations.
