[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0029] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0030] In some embodiments, please refer to Figures 1-5 of the accompanying drawings. A pipe spraying device includes a fixed plate 1, a connecting rod 2, an internal support fixing and moving mechanism 3, a surrounding cleaning mechanism 4, and an atomizing nozzle 5. A mounting plate 6 is fixedly installed on the right end of the fixed plate 1. An internal support fixing and moving mechanism 3 for controlling the device to perform spray cleaning inside the pipe is installed on the left end of the fixed plate 1 and the mounting plate 6. The internal support fixing and moving mechanism 3 includes a movable component 32 for controlling the contraction and expansion of multiple internal support plates 33, a drive component 31 for controlling the movement of the movable component 32, internal support plates 33, and self-driven universal wheels 34. The drive component 31 is installed on the fixed plate 1 and connected to the mounting plate 6. The connecting rod 2 is installed on the left end of the drive component 31. The movable component 32 is installed on the drive component 31 and the connecting rod 2. Multiple internal support plates 33 are installed on the outer ends of the movable component 32. Multiple self-driven universal wheels 34 that are rolled and connected to the inside of the pipe are provided on the outer ends of the internal support plates 33.

[0031] The fixed plate 1 and the connecting rod 2 are equipped with a surrounding cleaning mechanism 4 for cleaning the inside of the pipe and preventing the accumulation of spray dust;

[0032] The surrounding cleaning mechanism 4 includes a cleaning drive assembly, a cleaning angle adjustment assembly, and a cleaning brush plate 45; the cleaning drive assembly is mounted on the fixed plate 1, the connecting rod 2, and the mounting plate 6; the cleaning angle adjustment assembly is connected to the connecting rod 2 and is also connected to the cleaning drive assembly; the cleaning brush plate 45 is mounted on the cleaning angle adjustment assembly.

[0033] A misting nozzle 5 is installed on the left end of the cleaning drive assembly;

[0034] In this utility model, the operator places the device at the pipe opening, and then the drive component 31 works to drive the movable component 32 to move. The movable component 32 works to cause multiple inner support plates 33 to unfold outwards simultaneously until the self-driven universal wheels 34 set at the outer end of the inner support plates 33 abut against the inside of the pipe. Then the self-driven universal wheels 34 work to drive the device to move to a deeper position inside the pipe. Then the atomizing nozzle 5 works to generate a water curtain, which causes large dust particles in the pipe smoke to be absorbed by water droplets and settle to the bottom of the pipe. At this time, the cleaning brush plate 45 is in an inward retracted state and the cleaning brush plate 45 is not in contact with the inner wall of the pipe.

[0035] When it is necessary to clean the inner wall of the pipe, the cleaning drive component drives the cleaning angle adjustment component and the atomizing nozzle 5 to rotate. The atomizing nozzle 5 will then rotate to spray the inner wall of the pipe. At this time, the dust on the inner wall of the pipe will move along the inner wall of the pipe to the bottom of the pipe with the spray liquid.

[0036] The cleaning brush plate 45 of the cleaning angle adjustment component then rotates downwards until its lower end is in contact with the bottom of the pipe. The self-driving caster 34 then moves the device to the right, carrying dust from the deeper parts of the pipe. The device moves to the right until it reaches the right side of the pipe opening. The operator then removes the device and cleans away the dust carried by the cleaning brush plate 45. Through the cooperation of the drive component 31 and the movable component 32, the device can clean the inner walls of pipes with different inner diameters and perform cleaning spray operations on different parts of the pipe, improving its practicality. The cooperation of the cleaning drive component, the cleaning angle adjustment component, and the cleaning brush plate 45 allows the device to periodically clean scale and sludge from deeper parts of the pipe, maintaining pipe patency and spraying effectiveness, further enhancing its practicality.

[0037] As shown in Figures 1-5, the drive assembly 31 includes a lead screw 311, a first drive bevel gear 312, a first driven bevel gear 313, a first servo motor 314, and guide rods 315.

The right end of the lead screw 311 is rotatably connected to the fixed disk 1. The first driven bevel gear 313 is fixedly connected to the lead screw 311.

The output end of the first servo motor 314 is fixedly connected to the first drive bevel gear 312. The first driven bevel gear 313 meshes with the first drive bevel gear 312. Multiple guide rods 315 are fixedly installed between the left end of the fixed disk 1 and the right end of the connecting rod 2. The guide rods 315 are connected to the movable assembly 32.

[0038] As shown in Figures 1-5, the movable component 32 includes a fixed ring 321, a sliding ring 322, a driven support rod 323, and an active support rod 324. Two fixed rings 321 are fixedly installed on the outer ends of the connecting rod 2. The sliding ring 322 is threadedly connected to the lead screw 311. The sliding ring 322 is also slidably connected to the guide rod 315. The inner ends of multiple active support rods 324 are hinged to the outer ends of the sliding ring 322, and the outer ends of the active support rods 324 are hinged to the inner ends of the inner support plate 33. The inner ends of multiple driven support rods 323 are hinged to the outer ends of the fixed ring 321, and the outer ends of the driven support rods 323 are hinged to the inner ends of the inner support plate 33. The left end of the guide rod 315 is fixedly connected to the right fixed ring 321.

[0039] As shown in Figures 1-5, the cleaning drive assembly includes a second drive bevel gear 41, a second driven bevel gear 42, a second servo motor 43, and a rotating shaft 44. The second servo motor 43 is fixedly mounted on the upper end of the mounting plate 6; the second drive bevel gear 41 is rotatably mounted on the upper inner side of the mounting plate 6; the second driven bevel gear 42 is rotatably mounted on the right inner side of the mounting plate 6; the second drive bevel gear 41 and the second driven bevel gear 42 are meshed together; the output end of the second servo motor 43 is fixedly connected to the second drive bevel gear 41; the right end of the rotating shaft 44 is fixedly connected to the second driven bevel gear 42; the lead screw 311 and the connecting rod 2 are both sleeved on the outer end of the rotating shaft 44, and the rotating shaft 44 is rotatably connected to the middle of the lead screw 311 and the middle of the connecting rod 2; the rotating shaft 44 is also connected to the cleaning angle adjustment assembly; the atomizing nozzle 5 is fixedly mounted on the left end of the rotating shaft 44; the second driven bevel gear 42 is fixedly connected to the rotating shaft 44.

[0040] As shown in Figures 1-5, the cleaning angle adjustment assembly includes a rotary cylinder 46, a rotating rod 47, a mounting block 48, and a pneumatic-hydraulic slip ring 49. The mounting block 48 is fixedly mounted on the left end of the connecting rod 2. The rotating rod 47 is rotatably mounted on the lower end of the mounting block 48. The rotary cylinder 46 is fixedly mounted on the front end of the mounting block 48, and the output end of the rotary cylinder 46 is fixedly connected to the rotating rod 47. The cleaning brush plate 45 is hinged to the left end of the rotating rod 47. The rotating shaft 44 is rotatably connected to the middle of the mounting block 48.

[0041] A gas-liquid slip ring 49 is provided at the left end of the rotating shaft 44. The stator of the gas-liquid slip ring 49 is fixedly connected to the left end of the mounting block 48 via a connecting rod. The inner end of the rotor of the gas-liquid slip ring 49 is fixedly connected to the rotating shaft 44. The liquid guide pipe provided on the rotor of the gas-liquid slip ring 49 is connected to the water inlet of the atomizing nozzle 5. The liquid guide pipe provided on the stator of the gas-liquid slip ring 49 is connected to the water pump.

[0042] In this invention, the operator places the device at the pipe opening. Then, the first servo motor 314 drives the first drive bevel gear 312 to rotate. The first drive bevel gear 312 rotates, which in turn drives the first driven bevel gear 313 to rotate. The driven bevel gear 313 then drives the lead screw 311 to rotate. The rotation of the lead screw 311 causes the sliding ring 322 to move to the left along the guide rod 315. During this movement, the sliding ring 322 pushes the active support rod 324 to rotate the inner support plate 33 outwards. The inner support plate 33 then drives the driven support rod 323 to rotate outwards together until the self-driven universal wheel 34 on the inner support plate 33 is in contact with the inside of the pipe to be sprayed and cleaned. The self-driven universal wheel 34 then moves the device deeper into the pipe. The atomizing nozzle 5 then operates, generating a water curtain that causes large dust particles in the pipe's smoke and dust to be absorbed by water droplets and settle to the bottom of the pipe.

[0043] When it is necessary to clean the inner wall of the pipe, the second servo motor 43 drives the second drive bevel gear 41 to rotate, the second drive bevel gear 41 rotates, the second driven bevel gear 42 rotates, and the second driven bevel gear 42 drives the rotating shaft 44 to rotate. At this time, the atomizing nozzle 5 will rotate with the rotating shaft 44 to spray and clean the inner wall of the pipe. Then the dust on the inner wall of the pipe will move along the inner wall of the pipe to the bottom of the pipe with the spray liquid.

[0044] Then, the rotary cylinder 46 operates, driving the rotating rod 47 to rotate downwards. The rotating rod 47 drives the cleaning brush plate 45 to rotate downwards as well, so that the lower end of the cleaning brush plate 45 fits against the bottom of the pipe. Then, the self-driven caster wheel 34 operates, driving the device to move to the right. During the movement, the cleaning brush plate 45 will carry the dust at the bottom of the pipe to the right. Until the device moves to the right side of the pipe opening, the operator can then remove the device and clean up the dust carried out by the cleaning brush plate 45.
