Description

Technical Field

[0001] This application relates to the technical field of ultrasonic testing, and in particular to a single-station phased array ultrasonic water immersion testing device. Background Technology

[0002] With industrial development and technological progress, the demand for ultrasonic non-destructive testing equipment in the industrial testing field is also increasing.

[0003] Existing water immersion testing equipment includes a frame, a water tank, tooling and probes, and a circulating filtration system. The workpiece is clamped on the tooling and immersed in water. The probe is used to detect the workpiece, achieving precise positioning and complex path detection in three-dimensional space. The circulating filtration system is used to circulate and filter the pure water in the water tank to ensure the accuracy of the test results.

[0004] When purified water flows, air can easily enter and form bubbles. At the same time, the flow of purified water can also easily create ripples on the surface, causing the water to slosh around. Bubbles, ripples, and sloshing water can all adversely affect the probe's detection, reducing the accuracy of the test results. Summary of the Invention

[0005] To improve the accuracy of the test results, this application provides a single-station phased array ultrasonic water immersion testing device.

[0006] This application provides a single-station phased array ultrasonic immersion testing device, which adopts the following technical solution: A single-station phased array ultrasonic immersion testing device includes a housing, a water tank, tooling, a probe, and a circulating filtration device, wherein the circulating filtration device includes: The inlet and outlet pipes are connected to the water tank and are used for inputting and outputting water, respectively. A filtration system, connected to the output pipe, is used to filter water; A processing box is installed on the box body, and the top end of the input pipe is connected to the top of the processing box and the bottom end is connected to the bottom of the water tank. The limiting components are installed on the inner side wall of the box and located on the upper and lower sides of the connection between the input pipe and the processing box; The degassing mechanism is vertically slidably installed on the inner side wall of the processing box and cooperates with the processing box located below the degassing mechanism to form a degassing chamber; the degassing mechanism is moved to the upper and lower sides of the connection between the input pipe and the processing box and is positioned against the limiting component; The inlet pipe is connected to the bottom of the filtration mechanism and the degassing chamber and is used to input filtered pure water into the degassing chamber, so that the water enters the degassing chamber, pushes the degassing mechanism upward, and allows the gas in the water to be discharged through the degassing mechanism.

[0007] By adopting the above technical solution, the workpiece is installed on the tooling and immersed in water. The probe is activated and inserted into the water to detect the workpiece. After the detection is completed, it is removed and replaced. The water in the water tank is fed into the filtration mechanism through the output pipe for filtration. The filtered water is fed into the bottom of the degassing chamber through the inlet pipe. Then the water moves upward and contacts the degassing mechanism, pushing the degassing mechanism upward until it is positioned against the limit component. The water is then fed in through the inlet pipe, thereby realizing the circulation and filtration of pure water in the water tank.

[0008] The degassing mechanism floats on the water surface, stabilizing the surface and reducing ripples. When water enters the degassing chamber, it pushes the air upwards before it is expelled through the degassing mechanism. The upward movement of the water also causes the gas in the water to rise simultaneously, allowing it to be expelled quickly. The water flows downwards into the water tank through the input pipe, while the gas continues to rise and is expelled, making the expulsion of gas from the water faster and more efficient. This reduces interference from the gas in the water and water ripples on the detection, improving the accuracy of the detection results.

[0009] The degassing mechanism is first positioned on the limiting component, creating a gap between the outlet component and the bottom of the degassing chamber. This ensures the degassing chamber covers the entire lower surface of the degassing mechanism, allowing water to enter and contact the entire lower surface. This results in a more balanced thrust from the water on the degassing mechanism, making the gas discharge faster and more effective. Under gravity, the degassing mechanism exerts pressure on the water, allowing gas to be discharged more quickly and effectively. In particular, when the degassing mechanism moves upward and rests against the higher limiting component, the pressure on the water increases, further accelerating gas precipitation and improving the degassing effect and the accuracy of the detection results.

[0010] Optionally, the degassing mechanism includes: The buoyancy plate floats on the horizontal surface and has multiple ventilation holes. A waterproof and breathable membrane is installed on the buoyancy plate and blocks all the vents. The waterproof and breathable membrane is used to block water from passing through and to allow gas to pass through the vents. Multiple spikes are located on the lower surface of the buoyancy plate and around the vent holes to puncture air bubbles. An air-guiding component, installed on the buoyancy plate, is used to guide gas through the waterproof and breathable membrane and block external gas from passing through the waterproof and breathable membrane. The sealing assembly is slidably mounted on the processing box. After the buoyancy plate moves down, the sealing assembly is positioned on the bottom of the processing box and is used to seal the connection between the input pipe and the processing box. The buoyancy plate moves up to push the sealing assembly up and open it, so that the input pipe can communicate with the degassing chamber.

[0011] By adopting the above technical solution, the buoyancy plate floats on the water surface or contacts the limiting component for limiting. Multiple spikes can quickly and effectively puncture the air bubbles, allowing the gas inside the bubbles to be discharged through the waterproof and breathable membrane more quickly and effectively. The waterproof and breathable membrane blocks water from passing through, allowing the water to be discharged downwards through the input pipe, thereby achieving faster and better discharge of gas from the water.

[0012] The gas guiding component can collect the gas passing through the waterproof and breathable membrane before discharging it, thereby reducing the space for gas discharge and lowering the risk of external gas entering in reverse, which further improves the accuracy of the test results.

[0013] After the buoyancy plate moves down, the sealing component is positioned on top of the treatment tank under its own weight. The sealing component also seals the connection between the input pipe and the treatment tank, thus preventing external gas from entering the input pipe and reducing the risk of air entering the water through the input pipe after the buoyancy plate moves down. The upward movement of the buoyancy plate can push the sealing component to move up and open, thus connecting the input pipe and the degassing chamber, allowing water to enter the input pipe, further reducing the air content in the water and improving the accuracy of the test results.

[0014] Moreover, the sealing component is positioned under its own gravity. Compared to the sealing component being placed on the buoyancy plate, this reduces the space occupied by the buoyancy plate after pushing the sealing component upward, making the structure simpler and more stable, and further improving the accuracy of the test results.

[0015] Optionally, the air guiding assembly includes: An air duct is installed on the surface of the buoyancy plate and is used to collect gas passing through a waterproof and breathable membrane; The air duct is installed on the air duct cover and is equipped with a one-way valve for air venting only from the air duct cover.

[0016] By adopting the above technical solution, the gas guide hood is used to collect the gas passing through multiple vents and then discharge it through the gas guide pipe. At the same time, the setting of the gas guide one-way valve can prevent outside air from entering the water in reverse, further improving the accuracy of the test results.

[0017] Optionally, the plugging assembly includes: The sealing plate is vertically slidably installed on the inner side wall of the treatment box; A sealing ring is installed at the top of the sealing plate. After the sealing plate is moved down, the sealing ring is positioned on the top of the processing box and is used to seal the connection between the input pipe and the processing box.

[0018] By adopting the above technical solution, the buoyancy plate moves down, driving the sealing plate and sealing ring to move down, so that the sealing ring is positioned on the bottom of the treatment tank and seals the connection between the input pipe and the treatment tank. The buoyancy plate continues to move down and disengages from the sealing plate. After the buoyancy plate moves up, it pushes the sealing plate to move up, so that the input pipe and the degassing chamber are connected, thereby facilitating the entry of water into the input pipe.

[0019] Optionally, the limiting component includes: Limiting block one and limiting block two are vertically spaced on the inner side wall of the processing box; after the buoyancy plate moves down, it is placed on limiting block one for positioning, and after the buoyancy plate moves up to above the connection between the input pipe and the processing box, it abuts against the lower surface of limiting block two for positioning.

[0020] By adopting the above technical solution, limiting block one and limiting block two restrict the movement range of the buoyancy plate, thereby limiting the buoyancy plate and improving the accuracy of the detection results.

[0021] Optionally, the limiting block one and the limiting block two are detachably mounted on the inner side wall of the processing box, two buoyancy plates are vertically spaced and detachably connected, and the waterproof and breathable membrane is located between the two buoyancy plates and is positioned by being clamped by the two buoyancy plates.

[0022] By adopting the above technical solution, limiting block one and limiting block two are detachable, and the two buoyancy plates clamp the waterproof and breathable membrane for positioning. This makes it easy to remove the buoyancy plates from the processing box and replace the waterproof and breathable membrane. At the same time, the two buoyancy plates clamp the waterproof and breathable membrane, which can better achieve the positioning of the waterproof and breathable membrane, reduce the risk of the waterproof and breathable membrane detaching, and further improve the accuracy of the test results.

[0023] Optionally, the filtering mechanism includes: The filter box is mounted on the housing. The mounting box is placed on the upper surface of the filter box and its bottom is connected to the inside of the filter box, and both the mounting box and the filter box are in a closed state. A filter assembly is mounted on the mounting box and located above the filter box. The output pipe is connected to the bottom of the water tank and the upper surface of the mounting box, allowing water and impurities in the water tank to be filtered through the filter assembly. The pump body is installed on the upper surface of the filter box and is connected to the inlet pipe and the inside of the filter box, so that water in the filter box flows into the degassing chamber through the inlet pipe.

[0024] By adopting the above technical solution, the water and impurities in the tank can be easily moved to the filter assembly through the output pipe for filtration. Then, the water moves down and stays in the filter box, making the filter box full of water. The pump starts so that the filtered water flows into the degassing chamber through the input pipe, thereby achieving water filtration.

[0025] With the filter assembly located on the mounting box, which is situated on the upper surface of the filter box, water flows into the filter box for sedimentation before being drawn away by the pump. This design also prevents the filter assembly from contacting the water, facilitating subsequent cleaning of impurities within the filter assembly and improving the filtration effect and efficiency. Furthermore, the water is filtered in a relatively closed environment, reducing the risk of outside air entering the water and thus improving the accuracy of the test results.

[0026] Optionally, the mounting box has mounting holes, and the filter assembly includes: The filter frame is slidably mounted on the mounting hole and is used to filter water, and is provided with a mounting plate that abuts against the mounting box for positioning; The exhaust pipe is installed on the upper surface of the mounting box and is used to discharge the gas inside the mounting box. It is equipped with an exhaust check valve to prevent the entry of external gas.

[0027] By adopting the above technical solution, water is filtered through the filter frame, and the filtered water flows into the filter box for sedimentation. At the same time, gas is discharged through the exhaust pipe, and the exhaust one-way valve can prevent external gas from entering, thereby further reducing the gas in the water and improving the accuracy of the test results.

[0028] Optionally, two vertically arranged partitions are provided in the water tank, and the tooling is located between the two partitions. The two partitions are vertically spaced and each has a number of corresponding water passage holes. The bottom of the two partitions and the bottom of the water tank form a water passage cavity. The input pipe is connected to the bottom of the water passage cavity, so that water flows out through the water passage cavity and the multiple water passage holes, and laminar flow is formed at the workpiece.

[0029] By adopting the above technical solution, water enters the water tank through the input pipe. Due to the small space of the water passage cavity, some water flows out through the water passage cavity, while some water overflows and then enters the space between the two partitions through multiple water passage holes. Then, the water flows through the workpiece and is removed through the water passage cavity and multiple water passage holes. The water and impurities are then output through the output pipe, thereby forming a certain degree of laminar flow at the workpiece, which can reduce the risk of water turbulence at the workpiece and improve the accuracy of the test results.

[0030] Optionally, the water tank is equipped with a lifting assembly connected to the tooling. The lifting assembly is used to drive the tooling to move above the water surface or to drive the tooling and workpiece to be immersed in the water. The lifting assembly includes: The lifting platform is vertically slidably installed on the inner wall of the water tank and extends to the outer side of the water tank; The lifting component is installed on the outer wall of the water tank and connected to the lifting platform, and is used to drive the vertical movement of the lifting platform.

[0031] By adopting the above technical solution, the lifting component starts and drives the lifting platform, tooling, and workpiece to move up to the water surface, and then the workpiece is replaced. After the replacement is completed, the lifting component starts and drives the tooling and workpiece to move down, so that the workpiece is immersed in the water, which improves the convenience of workpiece replacement.

[0032] In summary, this application includes at least one of the following beneficial technical effects: 1. The degassing mechanism floats on the water surface to reduce water surface ripples. When water enters the degassing chamber, it pushes the air upwards to expel it. At the same time, the rising water level pushes the degassing mechanism upwards, thus allowing the gas in the water to be expelled as quickly as possible. The water flows downwards into the water tank through the input pipe, while the gas in the water continues to rise and is then expelled. This makes the expulsion of gas in the water faster and more effective, reducing the interference of gas in the water and water surface ripples on the detection and improving the accuracy of the detection results.

[0033] 2. By positioning the degassing mechanism on the limiting component, the thrust of water into the degassing mechanism is more even, making the degassing mechanism expel gas more quickly and effectively. At the same time, the degassing mechanism generates pressure on the water under gravity, allowing the gas in the water to be expelled faster and better under this pressure. In particular, when the degassing mechanism moves upward and abuts against the high limiting component, the pressure of the degassing mechanism on the water increases, which can further accelerate the precipitation of gas in the water, further improve the degassing effect, and further improve the accuracy of the detection results.

[0034] 3. After the buoyancy plate moves down, the sealing component moves down and is positioned on top of the treatment tank. The sealing component seals the connection between the input pipe and the treatment tank, thereby preventing external gas from entering the input pipe and reducing the risk of air entering the water through the input pipe after the buoyancy plate moves down. The upward movement of the buoyancy plate can push the sealing component upward and open, thus connecting the input pipe and the degassing chamber, allowing water to enter the input pipe, further reducing the air content in the water and improving the accuracy of the test results.

[0035] 4. Positioning of the sealing component under its own gravity, compared to placing the sealing component on the buoyancy plate, reduces the space occupied by the buoyancy plate after pushing the sealing component upward, making the structure simpler and more stable, and further improving the accuracy of the test results.

[0038] The following provides a further detailed description of this application.

[0039] This application discloses a single-station phased array ultrasonic water immersion testing device.

[0040] Reference Figure 1 The single-station phased array ultrasonic immersion testing equipment includes a housing 1, a water tank 11, a tooling 12, a probe 13, an operating table 17, and a circulating filter device 3. The operating table 17 is used to operate the equipment, and the circulating filter device 3 is activated to circulate and filter the pure water in the water tank 11 and remove the gas in the water.

[0041] Reference Figures 1-2A horizontal beam 14 is horizontally slidably installed on the upper surface of the water tank 11. The length directions of the horizontal beam 14 and the water tank 11 are parallel. The sliding direction of the horizontal beam 14 is perpendicular to its own length direction. A slide block 15 is slidably installed on the side wall of the horizontal beam 14 along its own length direction. A slide block 16 is vertically slidably installed on the slide block 16. Driving components are fixedly installed on the top of the water tank 11, the side wall of the horizontal beam 14, and the side wall of the slide block 15. The three driving components are used to drive the horizontal beam 14, the slide block 15, and the slide block 16 to move, respectively. The driving components adopt the driving structure in the prior art. The driving components can be electric push rods or motor screw and nut structures, etc.

[0042] A lifting assembly 2 connected to a tooling 12 is provided on the water tank 11. The lifting assembly 2 includes a lifting platform 21 and a lifting component 22. The lifting platform 21 is vertically slidably installed on the inner side of the water tank 11. The tooling 12 is fixedly installed on the upper surface of the lifting platform 21 by screws. The lifting component 22 is an electric push rod or a cylinder. Multiple lifting components 22 are arranged horizontally at intervals. The lifting components 22 are fixedly installed on the outer wall of the water tank 11, and the piston rod is set vertically upward. A connecting strip 26 is fixedly installed on the outer wall of the lifting platform 21, extending to the outside of the water tank 11 and fixedly connected to the piston rod of the lifting component 22. Multiple connecting strips 26 are provided and connected to multiple lifting components 22.

[0043] Multiple lifting components 22 are activated to drive the tooling 12 and the workpiece to move upwards above the water surface. The workpiece is then removed and replaced. The method of fixing the workpiece is selected according to the different workpieces, and a structure in the existing technology is used. After the replacement is completed, the lifting components 22 are activated to drive the lifting platform 21, the tooling 12 and the workpiece to move downwards, so that the workpiece is immersed in the water. The probe 13 moves downwards in both the horizontal and vertical directions, so that the probe 13 is immersed in the water, thereby realizing the detection of the workpiece.

[0044] Reference Figures 1-3 The circulating filtration device 3 includes an input pipe 31 and an output pipe 32, and a filtration mechanism 4. The input pipe 31 and the output pipe 32 are fixedly connected to both ends of the water tank 11 and communicate with the inside of the water tank 11. The bottom of the input pipe 31 and the top of the output pipe 32 are connected to the side near the bottom of the water tank 11.

[0045] Two partitions 23 are fixedly installed at intervals along the length of the inner side of the water tank 11. The tooling 12 and the lifting platform 21 are both located between the two partitions 23. The water level in the water tank 11 is flush with the top of the partitions 23 or located below the top of the partitions 23. Multiple water passage holes 24 are vertically spaced on both partitions 23. The water passage holes 24 are horizontal and extend to both sides of the tooling 12. A water passage cavity 25 is formed between the bottom of the partition 23 and the bottom wall of the water tank 11. The water passage cavity 25 is connected to the input pipe 31.

[0046] Water enters the water tank 11 through the input pipe 31. Due to the small space of the water passage chamber 25, some water flows through the water passage chamber 25, and some water overflows and then flows towards the workpiece through multiple water passage holes 24. Then, the water moves to the output pipe 32 through multiple water passage holes 24 and the water passage chamber 25, so that water and impurities are output through the output pipe 32. This makes laminar flow form at the workpiece. Laminar flow means that the fluid flows in layers, thereby improving the accuracy of the probe 13 during detection.

[0047] Reference Figures 1-4 The filtration mechanism 4 includes a filter box 41, a mounting box 42, a filter assembly 5, and a pump body 43. The filter box 41 is fixedly installed on the inner wall of the box 1 and is horizontal. The bottom of the mounting box 42 is fixedly installed on the upper surface of the filter box 41, and the bottom of the mounting box 42 communicates with the inside of the filter box 41, with both being closed. A mounting hole 44 is provided on the side wall of the mounting box 42. The filter assembly 5 is disposed on the mounting box 42 and located above the filter box 41. The bottom end of the output pipe 32 is fixedly connected to the upper surface of the mounting box 42, allowing water and impurities in the water tank 11 to move downwards to the filter assembly 5 for filtration. The filtered water is then moved into the filter box 41 for sedimentation. The pump body 43 is fixedly installed on the upper surface of the filter box 41 and communicates with the inside of the filter box 41. When the pump body 43 is activated, the settled water in the filter box 41 is discharged.

[0048] The filter assembly 5 includes a filter frame 51 and an exhaust pipe 52. The filter frame 51 is horizontally slidably mounted on the mounting hole 44. Multiple water supply holes are evenly opened on the inner bottom wall of the filter frame 51, and a mounting plate 45 is fixedly mounted on the outer wall of the filter frame 51 and positioned against the outer wall of the filter box 41. The exhaust pipe 52 is fixedly mounted on the upper surface of the mounting box 42 and is vertically upward. An exhaust one-way valve 53 is fixedly mounted on the exhaust pipe 52, so that only the gas inside the mounting box 42 can be discharged through the exhaust pipe 52.

[0049] Reference Figures 1-5 The circulating filtration device 3 also includes a processing box 33, a limiting component 6, a degassing mechanism 7, and an inlet pipe 34. The processing box 33 is fixedly installed on the inner wall of the box body 1, and the processing box 33 and the filter box 41 are located on both sides of the water tank 11, with the top of the processing box 33 open. The limiting component 6 is set on the inner wall of the box body 1 and is spaced vertically. The top of the inlet pipe 31 is connected to the top side wall of the processing box 33. The degassing mechanism 7 is vertically slidably installed on the inner wall of the processing box 33 and cooperates with the processing box 33 located below the degassing mechanism 7 to form a degassing chamber 35. In the initial state, the degassing mechanism 7 moves down under the action of gravity and is positioned on the limiting component 6 for positioning, or the degassing mechanism 7 moves up to the top of the inlet pipe 31 and abuts against the limiting component 6 for positioning.

[0050] Reference Figures 2-6The limiting component 6 includes a first limiting block 61 and a second limiting block 62. The first limiting block 61 and the second limiting block 62 are vertically spaced on the inner wall of the processing box 33, and multiple of them are horizontally arranged. At the same time, the connection between the input pipe 31 and the processing box 33 is located above the first limiting block 61 and below the second limiting block 62. The first limiting block 61 and the second limiting block 62 are both installed on the inner wall of the processing box 33 by plugging in the plug-in post, so as to realize the disassembly, assembly and replacement of the first limiting block 61 and the second limiting block 62.

[0051] The degassing mechanism 7 includes a buoyancy plate 71, a waterproof and breathable membrane 72, multiple spikes 73, a gas guiding component 8, and a sealing component 9. Two buoyancy plates 71 are vertically spaced and fixedly connected by screws. Multiple vertical vent holes 74 are evenly distributed on the buoyancy plates 71. The waterproof and breathable membrane 72 is located between the two buoyancy plates 71. The two buoyancy plates 71 fix the waterproof and breathable membrane 72 for fixation. At the same time, the two buoyancy plates 71 can be disassembled to replace the waterproof and breathable membrane 72. The waterproof and breathable membrane 72 blocks all the vent holes 74. Multiple spikes 73 are evenly fixedly installed on the lower surface of the lower buoyancy plate 71. Some spikes 73 are located around the vent holes 74. The spikes 73 are used to puncture air bubbles, so that gas can easily pass through the waterproof and breathable membrane 72 and the vent holes 74 and be discharged.

[0052] The air guiding component 8 is disposed on the buoyancy plate 71 and is used to discharge gas passing through the waterproof and breathable membrane 72 and to prevent external gas from passing through the waterproof and breathable membrane 72 in the reverse direction. The air guiding component 8 includes an air guiding cover 81 and an air guiding pipe 82. The air guiding cover 81 is fixedly installed on the upper surface of the upper buoyancy plate 71, and all the vent holes 74 are located inside the air guiding cover 81. The air guiding pipe 82 is fixedly installed on the air guiding cover 81 and is vertically upward. An air guiding one-way valve 83 is fixedly installed on the air guiding pipe 82. The air guiding one-way valve 83 allows only the gas located inside the air guiding cover 81 to be discharged, preventing external gas from entering the air guiding cover 81.

[0053] The inlet pipe 34 is fixedly installed on the pump body 43 and is connected to the bottom of the degassing chamber 35, so that the filtered and settled pure water is input into the degassing chamber 35. The water enters and pushes the gas to be discharged through the air guide pipe 82. At the same time, the water level rises and pushes the buoyancy plate 71, the air guide cover 81 and the air guide pipe 82 to move upward. Under the pressure of the buoyancy plate 71, the gas in the water continues to be discharged through the air guide pipe 82 until the air guide cover 81 abuts against the lower surface of the limit block 62 for positioning. The water is discharged through the inlet pipe 31 and enters the water tank 11.

[0054] Reference Figure 5 , Figures 7-8The sealing component 9 is slidably positioned at the top of the treatment tank 33. When the buoyancy plate 71 is located below the connection between the input pipe 31 and the treatment tank 33, the sealing component 9 is positioned on the top of the treatment tank 33 under the action of gravity, and is used to seal the connection between the input pipe 31 and the treatment tank 33, preventing outside air from entering the input pipe 31. After the buoyancy plate 71 moves upward, it can push the sealing component 9 to move upward and open, so that the input pipe 31 and the degassing chamber 35 are connected, allowing water to enter the input pipe 31 for transportation.

[0055] The sealing assembly 9 includes a sealing plate 91 and a sealing ring 92. The sealing plate 91 is vertically slidably installed on the inner side wall of the processing box 33. The sealing ring 92 is integrally set at the top of the sealing plate 91. Under the gravity of the sealing plate 91 and the sealing ring 92, the sealing ring 92 is pressed against the top of the processing box 33 for positioning. The sealing plate 91 seals the input pipe 31. After the buoyancy plate 71 moves upward, it drives the air guide hood 81 to push the sealing plate 91 and the sealing ring 92 upward at the same time until the air guide hood 81 abuts against the limit block 62 for positioning. At the same time, the buoyancy plate 71 moves downward, causing the sealing plate 91 to move back to continue sealing the connection between the input pipe 31 and the processing box 33.

[0056] The working principle of this application embodiment is as follows: The lifting assembly 2 is activated, driving the workpiece upwards to above the water surface. Workers then replace the workpiece, which is lowered and submerged in the water. Probe 13 moves and is submerged to inspect the workpiece. During inspection, impurities in the water enter the filter frame 51 through the output pipe 32 for filtration. The water flows into the filter box 41 for sedimentation. Gas in the water is discharged through the exhaust pipe 52. The pump 43 is activated, causing the settled water to enter the degassing chamber 35 through the inlet pipe 34. The gas in the degassing chamber 35 is compressed and discharged through the air guide pipe 82. The water level in the degassing chamber 35 rises, driving buoyancy. As plate 71 moves upward, the buoyancy plate 71 stabilizes the water level and forces the gas in the water to be expelled. The buoyancy plate 71 continues to move upward, driving the air guide hood 81 to push the sealing plate 91 upward until the air guide hood 81 abuts against the limiting block 62 for positioning. Water enters the water tank 11 through the input pipe 31, and then the water in the water tank 11 flows through multiple water holes 24 and water passage 25, forming laminar flow at the workpiece. Then, impurities and water continue to circulate through the output pipe 32, reducing the risk of ripples in the water, reducing the gas content, and improving the accuracy of detection.

[0057] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
