DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] In order to solve the inconvenience of technical problems that when the protective material is partially damaged, it needs to be dismantled and replaced as a whole, such as Figure 1 - Figure 8 As shown, the following preferred technical solutions are provided: A boiler water pipe protection device comprises a water pipe body 1 and a guide track 2 fixedly installed on the outer periphery of the water pipe body 1, the outer wall of the water pipe body 1 is coated with an anti-rust and high temperature resistant coating, the shape of the guide track 2 is set according to the direction of the water pipe body 1, and a plurality of guide tracks 2 can be set along the outer periphery of the water pipe body 1 according to the use needs, a driving component 3 is embedded and slidably installed on the guide track 2, one end of the driving component 3 is fixedly connected to a moving component 4, and the moving component 4 is slidably set on the outer wall of the guide track 2, the driving component 3 is used to pass the high temperature resistant and anti-rust coating from the outside, and at the same time, the moving component 4 is pushed to slide along the guide track 2 by the applied pressure, and a protective component 5 is fixedly connected to the outer wall of one side of the moving component 4, and the protective component 5 is used to detect the high temperature resistant and anti-rust coating on the outer wall of the water pipe body 1, and When it is worn, it is replenished in time, so as to achieve a better protection effect on the water pipe body 1. The outer periphery of the water pipe body 1 is sleeved with a repair component 6, and the repair component 6 is a circular ring structure as a whole. The protection component 5 is embedded and slidably connected with the end face of the repair component 6. One end of the moving component 4 is engaged with the outer ring of the repair component 6. One end of the moving component 4 drives the repair component 6 and the protection component 5 to slide relative to each other through the engagement, so that the repair component 6 rotates with the water pipe body 1 as the axis. One end of the driving component 3 is connected with one end of the protection component 5 through multiple hoses 7. An alarm 8 is fixedly installed on the moving component 4. When the water pipe body 1 is worn and the local wall thickness becomes smaller, the protection component 5 can also alarm it, prompting the staff to carry out maintenance in time, thereby further enhancing the protection of the water pipe body 1.

[0021] When the anti-corrosion and high-temperature resistant coating on the outer wall of the water pipe main body 1 is worn, the anti-corrosion and high-temperature resistant coating is squeezed into the driving component 3 by applying pressure through external equipment. While inputting the anti-corrosion and high-temperature resistant coating from the outside, the moving component 4 can also be pushed to slide along the guide track 2. The moving component 4 enters the boiler smoke box from the outside. Then, as the moving component 4 continues to move, the protective component 5 detects the change in coating thickness on the outer wall of the water pipe main body 1 through a retractable elastic structure. At the same time, the coating in the driving component 3 is gradually squeezed into the protective component 5 through the hose 7. When the protective component 5 detects an area where the coating thickness becomes thinner, one end of the protective component 5 is opened, and the anti-corrosion and high-temperature resistant coating is re-applied to the worn area, thereby protecting the water pipe main body 1.

[0022] During the movement of the moving component 4, one end of the moving component 4 drives the repair component 6 and the protective component 5 to slide relative to each other through the meshing action, so that the repair component 6 rotates with the water pipe body 1 as the axis. When the protective component 5 is re-coated with anti-rust and high-temperature resistant paint in the worn area, the repair component 6 flattens the extruded anti-rust and high-temperature resistant paint through rotating roller pressing, and at the same time evenly applies the excess paint on the side wall of the water pipe body 1 to repair some small wear holes. When the extension of one end of the protective component 5 is greater than the coating thickness, it means that there is local wear on the outer wall of the water pipe body 1. At this time, an alarm is issued through the alarm 8, so that the staff can be prompted to inspect and repair the water pipe body 1 in time, thereby achieving the protection effect of the water pipe body 1.

[0023] The guide track 2 includes a mounting seat 21 that is aligned with the water pipe body 1 . A slide groove 211 is provided on the mounting seat 21 . The drive assembly 3 is slidably mounted inside the slide groove 211 . A limiting protrusion 22 is symmetrically provided on the outer wall of the mounting seat 21 .

[0024] The driving assembly 3 includes a slide plate 31 and a sliding shaft 32 which are slidably connected to the inner wall of the slide groove 211. A pulley 33 is rotatably connected to the side wall of the sliding shaft 32. A feed pipe 34 is wound in the wheel groove of the pulley 33 to guide and tension the feed pipe 34 to prevent the feed pipe 34 from being offset and entangled with the device during movement. One end of the feed pipe 34 is connected to an external container of anti-rust and high-temperature resistant paint, and the other end of the feed pipe 34 is fixedly connected to a buffer cylinder 35. The end of the buffer cylinder 35 away from the feed pipe 34 is fixedly connected to the side wall of the slide plate 31. The anti-rust and high-temperature resistant paint enters the buffer cylinder 35 through the feed pipe 34, and the applied pressure acts on the slide plate 31, thereby pushing it to move.

[0025] A plurality of overflow holes 311 are provided on the side wall of the slide plate 31, one end of each of the overflow holes 311 is covered inside the buffer cylinder 35, and the other end of each of the overflow holes 311 is fixedly connected to a first connector 36, so that the paint can gradually overflow into the protective component 5 while pushing the slide plate 31 to move under the action of pressure.

[0026] The moving assembly 4 includes a moving plate 41 that slides against the outer wall of the mounting seat 21, and a first rotating shaft 42 is symmetrically connected to the bottom surface of the moving plate 41. A walking wheel 43 is fixedly installed at the bottom end of each first rotating shaft 42, and two limiting protrusions 22 are respectively clamped in the wheel grooves of the walking wheel 43 on the same side. When the moving plate 41 moves, the walking wheel 43 is rotated against the limiting protrusion 22, thereby driving the first rotating shaft 42 to rotate synchronously.

[0027] The protection component 5 includes an arc-shaped mounting plate 51 fixedly connected to the side wall of the movable plate 41, and a plurality of detection heads 52 are slidably connected to the side wall of the arc-shaped mounting plate 51, each detection head 52 is a hollow structure, one end of each detection head 52 is fixedly connected to a second connection head 53, each second connection head 53 is correspondingly connected to the first connection head 36 through a hose 7, and the other end of each detection head 52 is embedded with a rolling connection with a ball 58, and the ball 58 contacts the outer wall of the water pipe body 1, and each ball 58 They are all hollow structures, and a plurality of circular holes 581 are opened on the outer wall of each ball 58. The anti-corrosion and high-temperature resistant paint is squeezed out from the first connector 36 and enters the interior of the detection head 52 through the hose 7 and the second connector 53, and is finally squeezed out from the circular holes 581 of the ball 58 and coated on the outer wall of the water pipe body 1 to play a protective role. An annular protrusion 54 is integrally provided on the side wall of each detection head 52, and the top surface of each annular protrusion 54 is elastically connected to the side wall of the arc-shaped mounting plate 51 by a first spring 55.

[0028] Specifically, when in use, according to the protection requirements of the water pipe body 1 and the factors such as the direction of the smoke, a suitable number of guide rails 2 are fixedly installed along the water pipe body 1, and corresponding protective devices are installed on the guide rails 2. When the protective device is working, the anti-corrosion and high-temperature resistant paint is squeezed into the feed pipe 34 through pressure applied by external equipment, and the paint enters the buffer cylinder 35 after passing through the feed pipe 34, so that while the anti-corrosion and high-temperature resistant paint is input, the movable plate 41 can also be pushed to slide along the guide rail 2, and the movable plate 41 drives the entire device to move from the outside to the inside of the boiler smoke box, and then as the movable plate 41 continues to move, the paint gradually overflows from the overflow hole 311. It overflows to the first connector 36, further enters the interior of the detection head 52 through the hose 7 and the second connector 53, and is finally squeezed out from the circular hole 581 of the ball 58 to be coated on the outer wall of the water pipe body 1. Since the top surface of the annular protrusion 54 and the side wall of the arc-shaped mounting plate 51 are elastically connected by the first spring 55, the extension distance of the detection head 52 can be different according to the thickness of the coating on the outer wall of the water pipe body 1, thereby achieving the purpose of detecting the wear of the coating, and the anti-rust and high-temperature resistant coating can be re-applied on the worn area more accurately, thereby protecting the water pipe body 1 without disassembling the protective device.

[0029] In order to solve the technical problem that the side of the water pipe facing the smoke direction is more worn, while the other parts are relatively less worn, the protective materials of the undamaged parts are replaced without being fully utilized, resulting in material waste, such as Fig. 9 - Fig.10 As shown, the following preferred technical solutions are provided: The top end of one of the first rotating shafts 42 passes through the top wall of the moving plate 41, a vertical plate 44 is fixedly connected to the top surface of the moving plate 41, a second rotating shaft 45 is rotatably connected to the side wall of the vertical plate 44, the second rotating shaft 45 and one end of one of the first rotating shafts 42 are fixedly connected to a bevel gear 46, the two bevel gears 46 are meshed and connected, and a cylindrical gear 47 is fixedly connected to the outer wall of the second rotating shaft 45.

[0030] The protection assembly 5 also includes a plurality of gate plates 56 that are slidably connected to the side wall of the annular protrusion 54. Each gate plate 56 is located on the side wall at one end outside the annular protrusion 54 and is rotatably connected to a connecting rod 57. The end of each connecting rod 57 away from the gate plate 56 is rotatably connected to the side wall of the arc-shaped mounting plate 51.

[0031] The repair component 6 includes an outer gear ring 61, which is meshed with the cylindrical gear 47. Annular grooves 611 are provided on both side end faces of the outer gear ring 61. One side of the arc-shaped mounting plate 51 is slidably connected to the inside of the annular groove 611. A plurality of connecting frames 62 are fixedly connected to the side wall of the outer gear ring 61. Each connecting frame 62 is rotatably connected to a roller 63. Each roller 63 is tilted. The plurality of rollers 63 are arranged in a circular array. The outer gear ring 61 rotates with the water pipe body 1 as the axis and moves driven by the movable plate 41. The moving path of the contact point between the outer gear ring 61 and the water pipe body 1 is a spiral line, so the roller 63 is tilted at a certain angle to reduce resistance.

[0032] Specifically, when the detection head 52 is extended in the direction of the water pipe body 1, the multiple connecting rods 57 rotate outward and pull the gate plate 56 to move outside the annular protrusion 54, and the multiple gate plates 56 change from a gathered state to a dispersed state, so that the paint entering the interior of the detection head 52 can pass through. At the same time, according to the different extension lengths of the detection head 52, the opening degrees of the multiple gate plates 56 are different, so that different amounts of paint can be squeezed out according to different wear conditions. When one of the first rotating shafts 42 rotates, it drives the bevel gear 46 at one end thereof to rotate, and by meshing with another bevel gear 46 at one end of the second rotating shaft 45, the rotation of the first rotating shaft 42 can The second rotating shaft 45 can be driven to rotate, thereby driving the cylindrical gear 47 on the side wall of the second rotating shaft 45 to rotate. The cylindrical gear 47 is meshed with the outer gear ring 61 to make it rotate with the water pipe body 1 as the axis. When the detection head 52 re-coats the anti-corrosion and high-temperature resistant paint on the wear area, the roller 63 on the outer gear ring 61 rolls the extruded anti-corrosion and high-temperature resistant paint flat by rotating and rolling, and at the same time, the excess paint is evenly applied to the side wall of the water pipe body 1 to repair some small wear holes, so that different degrees of protection can be performed according to the wear condition of the water pipe body 1, and the protective material is fully utilized to reduce the waste of materials.

[0033] In order to solve the technical problem that local damage of protective materials is difficult to be discovered by staff in time, thus reducing its protective effect on the water pipe, such as Fig.11 As shown, the following preferred technical solutions are provided: A pressure sensor 59 is fixedly connected to the outer wall of each annular protrusion 54 , and one end of each pressure sensor 59 located inside the annular protrusion 54 is fixedly connected to a second spring 510 . One end of each second spring 510 away from the pressure sensor 59 is fixedly connected to the side wall of the gate plate 56 .

[0034] Specifically, when the gate plate 56 moves toward the outside of the annular protrusion 54, it can compress the second spring 510 and detect the pressure through the pressure sensor 59. When the coating and the body of the water pipe body 1 are worn, the extension of the detection head 52 exceeds the coating thickness. At this time, the compression of the second spring 510 is relatively large. After the pressure sensor 59 detects the abnormality, it activates the alarm 8, thereby prompting the operator to perform maintenance in time and strengthen the protection of the water pipe body 1.

[0035] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
