[0045] In order to make the content of the utility model more clearly understood, the utility model is further described in detail below based on specific embodiments and in conjunction with the accompanying drawings.

[0046] like Figures 1 to 4 As shown, a water removal device for steel pipe flaw detection equipment includes a frame 1, a lifting seat 2, a water collecting box 3, an air ring 4, a horizontal driving mechanism and a vertical driving mechanism;

[0047] The water collecting tank 3 is connected to the lifting seat 2 by sliding along the left-right direction;

[0048] The lateral driving mechanism is installed on the lifting seat 2, connected to the water collecting tank 3 and used to drive the water collecting tank 3 to move to a position in the left-right direction;

[0049] The lifting seat 2 is slidably connected to the frame 1 along the vertical direction;

[0050] The vertical driving mechanism is installed on the frame 1, connected to the lifting seat 2 and used to drive the lifting seat 2 to move up and down in the vertical direction;

[0051] The air ring 4 is installed in the water collecting box 3. The inner side of the air ring 4 is provided with a water blowing channel 6 for the steel pipe 5 to pass through. The water collecting box 3 is provided with an inlet channel 7 and an outlet channel 8. The steel pipe 5 passes through the inlet channel 7, the water blowing channel 6 and the outlet channel 8 in sequence.

[0052] The air ring 4 is used to connect to an external air source and blow air to the steel pipe 5 passing through the water blowing channel 6 to blow water on the surface of the steel pipe 5 into the water collecting box 3 .

[0053] Specifically, the steel pipe 5 coming out of the ultrasonic flaw detector 9 passes through the inlet channel 7, the water blowing channel 6 and the outlet channel 8 in sequence, and the air ring 4 is connected to an external air source. The compressed air in the external air source flows into the air ring 4 and then blows to the steel pipe 5 passing through the water blowing channel 6 to blow the coupling water on the surface of the steel pipe 5 into the water collecting box 3, so that the coupling water on the surface of the steel pipe 5 after detection can be blown clean, and the coupling water on the surface of the steel pipe 5 is removed. The water that falls is collected in the water collecting box 3, preventing the water from flowing everywhere along the steel pipe 5, thereby improving the production environment of the workshop. In addition, after removing the water on the surface of the steel pipe 5, it can also prevent the steel pipe 5 from being rusted during storage.

[0054] More specifically, the vertical drive mechanism can drive the lifting seat 2 to move in the vertical direction, thereby driving the water collecting box 3 to move up and down, and the horizontal drive mechanism can drive the water collecting box 3 to move in the left and right direction, thereby adjusting the up and down and left and right positions of the water collecting box 3 and the air ring 4 in the water collecting box 3, so that the steel pipe 5 can smoothly pass through the inlet channel 7, the water blowing channel 6 and the outlet channel 8, avoiding collision and interference between the steel pipe 5 and the water collecting box 3 and the air ring 4. And when drying steel pipes 5 of different diameters, the air ring 4 can be kept concentric with steel pipes 5 of various diameters by adjusting the up and down positions of the water collecting box 3 and the air ring 4.

[0055] like Figure 1 , 2 As shown, the transverse driving mechanism may include a transverse screw rod 10, a transverse nut and a transverse hand wheel 11;

[0057] The transverse nut is connected to the water collecting box 3 and is connected in cooperation with the transverse screw rod 10;

[0058] The transverse hand wheel 11 is connected to the transverse screw rod 10 , so that when the transverse hand wheel 11 is rotated, the transverse screw rod 10 is driven to rotate and then the transverse nut and the water collecting tank 3 are driven to move in the left and right directions.

[0059] like Figure 1 , 2 As shown, the vertical drive mechanism may include a screw lift 12 and a vertical hand wheel 13;

[0060] The screw lift 12 is connected to the frame 1, and the screw lift 12 is also connected to the lifting seat 2 and is used to drive the lifting seat 2 to move up and down;

[0061] The vertical hand wheel 13 is connected to the input shaft of the screw lift 12, so that when the vertical hand wheel 13 is rotated, the input shaft of the screw lift 12 is driven to rotate, and then the screw lift 12 drives the lifting seat 2 to move up and down relative to the frame 1, and then can drive the water collecting tank 3 to move up and down.

[0062] like Figures 1 to 4 As shown, the air ring 4 is provided with an annular air cavity 14;

[0063] The inner wall of the air ring 4 is provided with a plurality of air outlets 15 which are sequentially distributed along the circumferential direction and communicated with the annular air cavity 14;

[0064] The air ring 4 is also provided with an air inlet 16 which is connected to the air cavity 14 and is used to connect to the external air source; specifically, the compressed air in the external air source flows into the air cavity 14 from the air inlet 16, and then is blown out from the air outlet 15 and blown to the steel pipe 5 passing through the water blowing channel 6 to blow the water on the surface of the steel pipe 5 into the water collecting tank 3; in this embodiment, the air ring 4 is provided with a connecting ear, and the connecting ear is connected to the water collecting tank 3 so that the air ring 4 is connected to the water collecting tank 3.

[0065] like Figure 1 , 4As shown, the water removal device for steel pipe flaw detection equipment may also include a wiper mechanism 17 installed in the water collecting box 3, and the water collecting box 3 is also provided with a partition plate 100 located between the wiper mechanism 17 and the air ring 4, and the partition plate 100 is provided with a through hole 200 for the steel pipe 5 to pass through. The wiper mechanism 17, for example but not limited to the following structure, includes a guide rail frame 18, a left slide seat 19, a right slide seat 20, a left scraper 21, a right scraper 22 and an adjustment mechanism;

[0066] The guide rail frame 18 is connected in the water collecting tank 3;

[0067] The left slide 19 and the right slide 20 are respectively connected to the guide rail frame 18 in a sliding manner in the left and right directions;

[0068] The left scraper 21 is detachably connected to the left slide 19, and the right scraper 22 is detachably connected to the right slide 20. After passing through the inlet channel 7, the steel pipe 5 passes between the left scraper 21 and the right scraper 22 and then passes through the water blowing channel 6 and the outlet channel 8 in sequence.

[0069] The adjusting mechanism is respectively connected to the left slide 19 and the right slide 20 and is used to drive the left slide 19 and the right slide 20 to move toward each other so as to drive the left scraper 21 and the right scraper 22 to move toward each other until they respectively abut against the outer surfaces of the steel pipe 5. The adjusting mechanism is also used to drive the left slide 19 and the right slide 20 to move backwards and thereby drive the left scraper 21 and the right scraper 22 to move backwards until they are out of contact with the steel pipe 5.

[0070] Specifically, first select the left scraper 21 and the right scraper 22 of corresponding specifications according to the diameter of the steel pipe 5, install the left scraper 21 on the left slide 19, and install the right scraper 22 on the right slide 20, and then drive the left slide 19 and the right slide 20 to move toward each other through the adjusting mechanism, thereby driving the left scraper 21 and the right scraper 22 to move toward each other so that the left scraper 21 and the right scraper 22 respectively press against the outer surface of the steel pipe 5. At this time, as the steel pipe 5 moves forward, the coupling water on the surface of the steel pipe 5 can be scraped off by the left scraper 21 and the right scraper 22. Among them, it is difficult to completely blow away the water on the surface of the steel pipe 5 only by the wind ring 4. Therefore, most of the water on the surface of the steel pipe 5 is scraped off by the left scraper 21 and the right scraper 22 in the wiper mechanism 17, and then the remaining water on the surface of the steel pipe 5 is blown away by the wind ring 4. The combination of scraping and blowing is used to perform joint water removal operations, which effectively removes the remaining coupled water on the surface of the steel pipe after inspection, saves resources, and avoids quality problems caused by rust on the steel pipe surface.

[0071] To be more specific, when the diameter of the steel pipe 5 is different, the spacing between the left scraper 21 and the right scraper 22 is also different. Therefore, it is necessary to drive the left slide 19 and the right slide 20 to move toward or away from each other through an adjustment mechanism, thereby driving the left scraper 21 and the right scraper 22 to move toward or away from each other to adjust the spacing between the left scraper 21 and the right scraper 22, so that the left scraper 21 and the right scraper 22 can perfectly rest against the outer surface of the steel pipe 5.

[0072] like Figure 4 As shown, the adjustment mechanism may include a double-headed screw 23, a left nut 24, a right nut 25 and an adjustment hand wheel 26;

[0073] The double-headed screw 23 is rotatably connected to the guide rail frame 18, and a first threaded portion 27 and a second threaded portion 28 are provided on the double-headed screw 23, and the rotation direction of the first threaded portion 27 is opposite to the rotation direction of the second threaded portion 28;

[0074] The left nut 24 is connected to the left sliding seat 19 and is connected in cooperation with the first threaded portion 27;

[0075] The right nut 25 is connected to the right sliding seat 20 and is connected in cooperation with the second threaded portion 28;

[0076] The adjusting hand wheel 26 is connected to the double-headed screw 23 and is used to drive the double-headed screw 23 to rotate, and then drive the left nut 24 and the right nut 25 to move toward or away from each other through the first threaded portion 27 and the second threaded portion 28, and then drive the left slide 19 and the right slide 20 to move toward or away from each other, and then make the left scraper 21 and the right scraper 22 move toward or away from each other.

[0077] like Figure 4 As shown, the left scraper blade 21 and the right scraper blade 22 are respectively provided with arc portions adapted to the outer diameter of the steel pipe 5 .

[0078] like Figure 1 , 2 As shown, the water removal device for steel pipe flaw detection equipment may also include a front supporting wheel 29 and a rear supporting wheel 30;

[0079] The front supporting wheel 29 and the rear supporting wheel 30 are respectively rotatably connected to the frame 1 and are respectively used to support the steel pipe 5;

[0080] The water collecting tank 3 is located between the front supporting wheel 29 and the rear supporting wheel 30 .

[0081] like Figure 3 , 4As shown, the bottom of the water collecting box 3 is a conical structure that is larger at the top and smaller at the bottom, and a drain outlet 31 is provided at the bottom of the water collecting box 3; specifically, setting the bottom of the water collecting box 3 into a conical structure is conducive to discharging water in the water collecting box 3 from the drain outlet 31.

[0082] In this embodiment, the water removal device for steel pipe flaw detection equipment may also include a sensor 32, a controller and a solenoid valve;

[0083] The air ring 4 is connected to an external air source through an air guide pipe, and the solenoid valve is connected in the air guide pipe;

[0084] The sensor 32 is connected to the controller, and the sensor 32 is used to send a signal to the controller when detecting that the steel pipe 5 passes through the inlet channel 7;

[0085] The controller is connected to the solenoid valve and is used to control the opening and closing of the solenoid valve according to the signal sent by the sensor 32 .

[0086] In summary, the steel pipe 5 coming out of the ultrasonic flaw detector 9 passes through the inlet channel 7, the water blowing channel 6 and the outlet channel 8 in sequence, and the air ring 4 is connected to an external air source. The compressed air in the external air source flows into the air ring 4 and then blows to the steel pipe 5 passing through the water blowing channel 6 to blow the coupling water on the surface of the steel pipe 5 into the water collecting box 3, so that the coupling water on the surface of the steel pipe 5 after detection can be blown clean, and the coupling water on the surface of the steel pipe 5 is removed. The water that falls is collected in the water collecting box 3, preventing the water from flowing everywhere along the steel pipe 5, thereby improving the production environment of the workshop. In addition, after removing the water on the surface of the steel pipe 5, it can also prevent the steel pipe 5 from being rusted during storage. The vertical drive mechanism can drive the lifting seat 2 to move in the vertical direction, and then can drive the water collecting box 3 to move up and down, and the horizontal drive mechanism can drive the water collecting box 3 to move in the left and right direction, and then can adjust the up and down and left and right positions of the water collecting box 3 and the air ring 4 in the water collecting box 3, so that the steel pipe 5 can smoothly pass through the inlet channel 7, the water blowing channel 6 and the outlet channel 8, and avoid collision and interference between the steel pipe 5 and the water collecting box 3 and the air ring 4. And when drying steel pipes 5 of different diameters, by adjusting the up and down positions of the water collecting box 3 and the air ring 4, the air ring 4 can be kept concentric with the steel pipes 5 of various diameters.
