[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1: In the present invention, the scraper is in contact with the outer wall of the tube body, and the scraper can be used to scrape the dirt on the outer wall of the tube body. The scraper can be in contact with the outer wall of the tube body and move along the path of the tube body during rotation, so that the dirt on the outer wall of the tube body can be completely scraped off.

[0018] 2: In the present invention, the rotation of the mounting ring can drive the rotation of the fixed block, and the rotation of the fixed block can drive the rotation of the fan blade plate. The multiple fan blade plates on the outer wall of the mounting ring rotate with the mounting ring. The fan blade plates can be used to fan the high-temperature steam in the shell, so that the high-temperature steam entering the shell through the steam port is fanned by the fan blade plates and evenly filled in the shell, so that the high-temperature steam in the shell can be contacted with the pipe body faster and more comprehensively to exchange heat with the cooling inside the pipe body. The fan blade plates can be used to fan the high-temperature steam in the shell evenly to assist the rapid heat exchange of the cold water in the pipe body.

[0019] 3: In the present invention, the hydrophone is rotated around the tube body to adjust the position of the hydrophone. When a water leakage detection is required for a certain point on the tube body, the hydrophone is moved to the point to be detected, and the air pump is started to inflate the inflatable airbag sleeve to reduce the inner diameter of the inflatable airbag sleeve, so that the hydrophone fits the tube body and the water leakage detection can be performed at that position. It can perform a comprehensive water leakage detection on the tube body to avoid the difficulty in timely detection of water leakage in the tube body.

[0020] 4: In the present invention, the installation frame moves toward the pipe body. Since the hydrophone fits the leaking point on the pipe body and the hydrophone is located in the inner circle of the installation frame, the leaking point is also in the inner circle of the installation frame. At this time, the installation frame moves toward the pipe body until the water-absorbing sponge ring at the bottom of the installation frame contacts the pipe body. The water-absorbing sponge ring that absorbs ink can be used to smear ink on the pipe body, so that the leaking point detected by the hydrophone can be marked. The leaking point on the pipe body can be marked, which is convenient for quick search of the leaking point of the pipe body at a later time, and convenient for repairing the leaking point of the pipe body.

[0021] 5: In the present invention, the inner diameter of the circle formed by the several scrapers is consistent with the outer diameter of the tube body. Through the coordinated use of the first electric slider and the first guide rail, the deformation of the tube body can be detected during the rotation and movement of the circle formed by the several scrapers. If the rotating and moving scrapers only contact the outer wall of the tube body, the tube body is not deformed. If the rotating and moving scrapers interfere with the tube body, it is determined that the tube body is deformed. The deformation of the tube body can be detected by using the several rotating and moving scrapers. BRIEF DESCRIPTION OF THE DRAWINGS

An annular mounting groove 42 is opened on the inner wall of the mounting ring 21, and the inflatable airbag cover 29 is installed in the mounting groove 42. The mounting groove 42 can provide a mounting surface for the inflatable airbag cover 29 and limit the inflatable airbag cover 29 so that when the inflatable airbag cover 29 is inflated, it can only expand toward the inner circle of the inflatable airbag cover 29, so that the inner diameter of the inflatable airbag cover 29 is reduced.

[0046] As a technical optimization solution of the present invention, blocks are installed at both ends of the first guide rail 2, and the blocks are installed on the side of the copper plate 1. The blocks can provide limiting for the first electric slider 11 to prevent the first electric slider 11 from detaching from the first guide rail 2.

[0047] As a technical optimization solution of the present invention, a circle of welding parts is set at the edges of both sides of the copper plate 1, and the welding parts facilitate welding the copper plate 1 in the opening of the shell 3, thereby facilitating the connection between the copper plate 1 and the shell 3.

[0048] As a technical optimization solution of the present invention, an opening is provided on one side of the shell 3, the copper plate 1 is installed in the opening, the tube body 10 is located in the shell 3, a water outlet port 4 is provided on the top of the shell 3, the water outlet port 4 is connected to the water outlet 15, a water inlet port 8 is provided at the bottom of the shell 3, the water inlet port 8 is connected to the water inlet 16, a steam port 7 is provided on the side of the shell 3, the steam port 7 is connected to the shell 3, a condensate port 9 is provided at the bottom of the shell 3, the condensate port 9 is connected to the shell 3, two support plates 5 are symmetrically installed at the bottom of the shell 3, and a bottom plate 6 is installed at the bottom of the support plate 5.

[0049] When the present invention is in use, first, high-temperature steam is introduced into the shell 3 through the steam port 7, and cold water enters the tube body 10 through the water inlet port 8 and the water inlet 16. The cold water entering the tube body 10 absorbs the high-temperature steam in the shell 3 through the tube body 10, thereby causing the cooling inside the tube body 10 to be heated and heated for heat exchange. By making the tube body 10 into a bow shape, the travel of the cold water in the tube body 10 can be lengthened, and the contact time between the cold water in the tube body 10 and the high-temperature steam in the shell 3 through the tube body 10 is increased, thereby ensuring the heat exchange of the cold water in the tube body 10. After the heat exchange of the cold water in the tube body 10 is completed, the water is discharged through the water outlet 15 and the water outlet port 4.

[0050] When the tube body 10 is used for a long time and the outer wall of the tube body 10 is scaled, the motor 22 is started, and the output shaft of the motor 22 drives the gear 23 to rotate. The rotation of the gear 23 causes the gear ring 24 to rotate, and then the mounting ring 21 rotates, and the mounting ring 21 can slide in the limiting slide groove 39 of the limiting block 19. After the mounting ring 21 rotates, the air pump is started to inflate the inflatable airbag sleeve 29, and the inflatable airbag sleeve 29 is limited by the mounting groove 42 provided on the inner wall of the mounting ring 21. When the inflatable airbag sleeve 29 is inflated, it can only expand toward the inner circle of the inflatable airbag sleeve 29, thereby reducing the inner diameter of the inflatable airbag sleeve 29 until the scraper 27 contacts the outer wall of the tube body 10. At this time, the first electric slider 11 is started, and the first electric slider 11 slides on the first guide rail 2. Because the path of the first guide rail 2 is the same as the path of the tube body 10, when the first electric slider 11 slides on the first guide rail 2, it can pass through the first electromagnet 13 and the second electromagnet 1 8, the second fixed plate 17 follows the movement path of the first electric slider 11 to move in the same path, thereby driving the mounting ring 21 to move along the shape of the tube body 10, so that the mounting ring 21 can always be sleeved on the tube body 10, and the inflatable airbag sleeve 29 can be rotated by the rotation of the mounting ring 21, thereby rotating the scraper 27, and the scraper 27 is in contact with the outer wall of the tube body 10, so that the scraper 27 can be used to scrape the dirt on the outer wall of the tube body 10, and the contact with the outer wall of the tube body 10 and the movement of the scraper 27 along the path of the tube body 10 during the rotation of the scraper 27 can be used to comprehensively scrape the dirt on the outer wall of the tube body 10, and the descaling process of the tube body 10 can be completed without stopping the machine, and the dirt on the outer wall of the tube body 10 can be scraped without removing the tube body 10 from the shell 3, and the dirt on the outer wall of the tube body 10 can be removed without stopping the machine.

[0051] When the scraper 27 contacts the outer wall of the tube body 10, the wiping sponge block 28 also contacts the outer wall of the tube body 10. At the same time, the wiping sponge block 28 is used to wipe the outer wall of the tube body 10 to remove the dirt attached to the outer wall of the tube body 10, and the scraper 27 is used to clean the outer wall of the tube body 10 to improve the cleaning effect of the outer wall of the tube body 10.

[0052] And when the mounting ring 21 rotates, the rotation of the mounting ring 21 can drive the fixed block 25 to rotate, and the rotation of the fixed block 25 can drive the fan blade plate 26 to rotate. The several fan blade plates 26 on the outer wall of the mounting ring 21 rotate with the mounting ring 21. The fan blade plates 26 can be used to fan the high-temperature steam in the shell 3, so that the high-temperature steam entering the shell 3 through the steam port 7 is fanned by the fan blade plates 26 and evenly filled in the shell 3, so that the high-temperature steam in the shell 3 can be more quickly and comprehensively contacted with the tube body 10 to exchange heat with the cooling inside the tube body 10. The fan blade plates 26 can be used to fan the high-temperature steam in the shell 3 evenly, and assist the cold water in the tube body 10 to quickly exchange heat.

[0053] In addition, the air pump is started to inflate the inflatable airbag sleeve 29, so that the inflatable airbag sleeve 29 expands and its inner diameter becomes smaller, until the hydrophone 30 installed on the inner wall of the inflatable airbag sleeve 29 contacts the tube body 10, and the hydrophone 30 is attached to the tube body 10 to detect whether there is a water leak on the tube body 10. In addition, the installation ring 21 can be moved along the path of the tube body 10 by the cooperation of the first electric slider 11 and the first guide rail 2, and the output shaft of the motor 22 drives the gear 23 to rotate. The gear ring 24 drives the mounting ring 21 to rotate, and then the hydrophone 30 rotates around the tube body 10 to adjust the position of the hydrophone 30. When a water leakage detection is required for a certain point on the tube body 10, the hydrophone 30 is moved to the point to be detected, and the air pump is started to inflate the inflatable airbag sleeve 29 to reduce the inner diameter of the inflatable airbag sleeve 29, so that the hydrophone 30 fits with the tube body 10, and the water leakage detection can be performed at that position. It can perform a comprehensive water leakage detection on the tube body 10 to avoid the difficulty in timely detection of water leakage in the tube body 10.

[0054] Furthermore, when the hydrophone 30 detects a leak in the tube body 10, the hydrophone 30 fits the leak on the tube body 10, and the liquid pump is started. The liquid pump can extract the ink in the ink tank 35 into the bellows through the bellows, and the ink enters the water-absorbing sponge ring 34 through the bellows. At this time, the second electric slider 32 is started, and the second electric slider 32 slides on the second guide rail 31, which can drive the installation frame 33 to move closer to the tube body 10. Because the hydrophone 30 fits the leak on the tube body 10, the hydrophone 30 0 is located in the inner circle of the installation frame 33, then the leaking point is also in the inner circle of the installation frame 33, and at this time the installation frame 33 moves closer to the tube body 10 until the water-absorbing sponge ring 34 at the bottom of the installation frame 33 contacts the tube body 10, and the water-absorbing sponge ring 34 that absorbs ink can be used to apply ink on the tube body 10, so that the leaking point detected by the hydrophone 30 can be marked, and the leaking point on the tube body 10 can be marked, which is convenient for quick search of the leaking point of the tube body 10 in the later stage, and convenient for repairing the leaking point of the tube body 10.

[0055] The inflatable airbag sleeve 29 is inflated by an air pump so that the scraper 27 contacts the outer wall of the tube body 10, and the motor 22 drives the gear 23 to rotate so that the gear ring 24 drives the mounting ring 21 to rotate, so that the scraper 27 can be rotated, and the inner diameter of the circle formed by the plurality of scrapers 27 is kept consistent with the outer diameter of the tube body 10. Through the coordinated use of the first electric slider 11 and the first guide rail 2, the circle formed by the plurality of scrapers 27 can be used to detect whether the tube body 10 is deformed during the rotation and movement process. If the rotating and moving scraper 27 only contacts the outer wall of the tube body 10, the tube body 10 is not deformed. If the rotating and moving scraper 27 interferes with the tube body 10, it is determined that the tube body 10 is deformed. The rotating and moving scrapers 27 can be used to detect whether the tube body 10 is deformed.

[0056] When there is a leak on the outer wall of the tube body 10, the water in the tube body 10 can be drained, and the air pump can be started to expand the inflatable airbag sleeve 29, thereby reducing the inner diameter of the inflatable airbag sleeve 29, so that the scraper 27 and the wiping sponge block 28 are in contact with the outer wall of the tube body 10. The installation ring 21 is rotated to rotate the wiping sponge block 28 to wipe off the condensed water attached to the outer wall of the tube body 10, so as to avoid the condensed water at the leak point on the outer wall of the tube body 10 affecting the welding. After the condensed water at the leak point on the outer wall of the tube body 10 is wiped clean, the welding gun head 38 is adjusted Go to the side of the leakage point, start the electric telescopic rod 37 and the welding gun head 38, the piston rod of the electric telescopic rod 37 pushes the welding gun head 38 toward the leakage point of the tube body 10, and uses the welding gun head 38 to weld the leakage point of the tube body 10. The welding process of the tube body 10 can be completed without disassembling the tube body 10. The leakage point on the tube body 10 that is easy to be repaired by welding can be repaired by welding without disassembling the tube body 10. The specific working condition and appearance of the tube body 10 can be observed by using the camera 41.

[0057] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
