[0023] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below with reference to specific embodiments and the accompanying drawings.

[0024] The terms used in the present invention are those commonly used in the art in view of the functions of the present invention, but these terms may vary according to the intentions of those skilled in the art, precedents, or new technologies in the art. In addition, specific terms may be selected by the applicant, and in such cases, their detailed meanings will be described in the detailed description of the present invention. Therefore, the terms used in the specification should not be understood as simple names, but rather as the meanings of the terms and the overall description of the present invention.

[0025] Reference Figures 1 to 4 This embodiment provides a screen-type superheater cleaning device, including a first cleaning part 1 hingedly connected to a second cleaning part 2, and symmetrical walking parts 3 are installed on the first cleaning part 1 and the second cleaning part 2; after the first cleaning part 1 and the second cleaning part 2 are closed, they clean the superheater, and the walking part 3 drives the first cleaning part 1 and the second cleaning part 2 to move on the superheater.

[0026] Furthermore, the first cleaning part 1 includes: a mounting plate 11, a first light rod 12 and a first screw 13 are mounted on the mounting plate 11, a rotary switch 18 is mounted on one side of the first screw 13, a first cleaning rod 14 is sleeved on the first light rod 12 and the first screw 13, a magnetic sheet is mounted on one side of the first cleaning rod 14; a first cleaning brush 16, the first cleaning brush 16 is connected to the first cleaning rod 14 through a first spring rod 15.

[0027] Among them, the end close to the mounting plate 11 is rotatably connected to the first screw 13 and fixedly connected to the first polished rod 12. A through hole is opened on the mounting plate 11, and the rotary switch 18 is fixed to the first screw 13 through the through hole. By rotating the rotary switch 18, the first screw 13 is driven to rotate. One end of the first cleaning rod 14 is sleeved on the first polished rod 12, and the other end of the first cleaning rod 14 is screwed on the first screw 13. When the first screw 13 rotates, the first cleaning rod 14 is driven to move on the first screw 13 and the first polished rod 12.

[0028] The movement of the first cleaning rod 14 adjusts the distance between the first cleaning brush 16 and the superheater. A first spring rod 15 is installed between the first cleaning brush 16 and the first cleaning rod 14. The first spring rod 15 adjusts the pressure of the first cleaning brush 16 on the superheater, thereby increasing the cleaning degree of the first cleaning brush 16 on the superheater.

[0029] Furthermore, the first cleaning part 1 includes a water tank 17, which is fixedly connected to one side of the mounting plate 11. A push-pull switch 115 is installed at the bottom of the water tank 17. A through hole corresponding to the push-pull switch 115 is opened on the mounting plate 11, and side panels 19 are fixedly connected to both ends of the mounting plate 11.

[0030] The first cleaning part 1 also includes: a first cavity 111 and a second cavity 112, which are fixedly connected to one side of the mounting plate 11. The first cavity 111 and the second cavity 112 are connected by a high-pressure pump 113, and a push-pull switch 115 is located above the second cavity 112; a nozzle 114 is installed on one side of the first cavity 111 and the second cavity 112.

[0031] Among them, the water tank 17 is located above the mounting plate 11, and is used to supply water to the first cavity 111 and the second cavity 112. At the same time, the first cavity 111 and the second cavity 112 transfer liquid through the high-pressure pump 113. When the push-pull switch 115 is pulled open, the water tank 17 supplies water to the second cavity 112, and the high-pressure pump 113 draws water from the second cavity to the first cavity. Therefore, the first cavity 111 can be a high-pressure water area and the second cavity can be a conventional water pressure area, so that the nozzle 114 on one side sprays high-pressure water to perform preliminary dust removal and softening on the superheater, and the nozzle 114 on the other side further rinses the cleaned superheater to flush away the dirt.

[0032] Specifically, the second cleaning part 2 includes: an installation box 21 , and a side wall of the installation box 21 is hinged to the side plate 19 .

[0033] Furthermore, the second cleaning part 2 also includes: a second light rod 22, installed on the inner wall of the mounting box 21; a second screw 23, installed on the inner wall of the mounting box 21; a second cleaning rod 24, the second cleaning rod 24 is sleeved on the second light rod 22 and the second screw 23, the second cleaning brush 26 is connected to the second cleaning rod 24 through a second spring rod 25, and a magnetic sheet is installed on one side of the second cleaning rod 24.

[0034] Among them, the mounting box 21 is hinged to the side panel 19, so that the first cleaning part 1 and the second cleaning part 2 can be opened and closed, and the second light rod 22, the second screw rod 23, the second cleaning rod 24, the second cleaning brush 26, and the second spring rod 25 have the same movement mode as the first light rod 12, the first screw rod 13, the first cleaning rod 14, the first cleaning brush 16, and the first spring rod 15 in the first cleaning part 1.

[0035] The first screw 13 and the second screw 23 achieve common movement through the action of the cross pin. When the rotary switch 18 is rotated, the second screw 23 is driven to rotate. The first screw 13 and the second screw 23 form a bidirectional screw, so that when the rotary switch 18 is rotated, the first cleaning brush 16 and the second cleaning brush 26 can move relative to each other.

[0036] Furthermore, a U-shaped groove 191 is provided in the side panel 19, and a first L-shaped rod 192 is slidably connected in the U-shaped groove 191, and a magnetic piece is installed at one end of the first L-shaped rod 192. A telescopic rod 193 is fixedly connected in the U-shaped groove 191, and a wedge-shaped rod 194 is fixedly connected at one end of the telescopic rod 193. An L-shaped groove 211 is provided in the side wall of the installation box 21, and the L-shaped groove 211 is connected to the straight groove 195. A second L-shaped rod 222 is slidably connected in the L-shaped groove 211, and a magnetic piece is installed at one end of the second L-shaped rod 222.

[0037] Among them, the first cleaning rod 14 and the second cleaning rod 24 are installed with magnetic plates at the ends near the first screw 13 and the second screw 23. The magnetic plate at one end of the first cleaning rod 14 is attracted to the magnetic plate at one end of the first L-shaped rod 192, and the magnetic plate at one end of the second cleaning rod 24 is attracted to the magnetic plate at one end of the second L-shaped rod. When the rotary switch 18 drives the first screw 13 and the second screw 23 to rotate, the first cleaning rod 14 drives the first L-shaped rod 192 to slide in the U-shaped groove 191, and the middle part of the wedge-shaped rod 194 is wedge-shaped. When the first L-shaped rod 192 moves downward, the first L-shaped rod 192 slides on the wedge-shaped surface in the middle of the wedge rod 194, pushing the wedge rod 194, and the telescopic rod 193 is in a stretched state at this time.

[0038] The rotation of the second screw 23 drives the movement of the second cleaning rod 24, and then drives the second L-shaped rod 222 to slide in the L-shaped groove 211 and slide into the straight groove 195. At the same time, the U-shaped groove 191 is connected to the straight groove 195. A groove is provided on the second L-shaped rod 222. The first L-shaped rod 192 pushes the wedge-shaped rod 194 to insert into the groove of the second L-shaped rod 222, thereby locking the first cleaning part 1 and the second cleaning part 2.

[0039] Specifically, the walking part 3 includes a third spring rod 31 fixedly connected at both ends of the first cleaning rod 14 and the second cleaning rod 24 , one end of the third spring rod 31 is fixedly connected to a driving wheel 32 , and a driving motor 33 is installed on one side of the driving wheel 32 .

[0040] Among them, the driving wheel 32 moves simultaneously with the first cleaning rod 14 and the second cleaning rod 24. The driving wheel 32 is higher than the first cleaning brush 16 and the second cleaning brush 26. When the first cleaning brush 16 and the second cleaning brush 26 are close to the superheater and pressure is generated on the contact surface, the driving wheel 32 is able to just contact the superheater. The third spring rod 31 on one side of the driving wheel 32 enables the driving wheel 32 to have a distance adjustment effect, avoiding the first cleaning rod 14 and the second cleaning rod 24 from being too close to the superheater pipe. The driving wheel 32 can also move on the superheater.

[0041] Finally, it should be pointed out that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways without departing from the scope of the present invention.
