[0002] Current boiler flue cleaning methods typically rely on manual cleaning, which has drawbacks such as dependence on manual brush operation, high labor intensity, potential safety hazards, and difficulty in covering long flue pipes. To improve cleaning efficiency, engineers have developed numerous boiler flue cleaning devices. However, existing cleaning devices are mostly fixed structures, unable to be flexibly adjusted according to flue pipe dimensions, and lack integrated functions such as real-time monitoring and simultaneous dust collection, as well as modular design. Summary of the Invention

[0003] The technical problem to be solved by this invention is to provide a modular small boiler flue cleaning device. This device can move autonomously inside the flue, is miniaturized and modular, and integrates cleaning, dust collection, visual monitoring and remote control functions, thus solving the problems of low efficiency, dangerous operation and difficulty in adapting to narrow flue environments of traditional cleaning technology.

[0004] To solve the above problems, the specific technical solution created by the present invention is as follows: A modular small boiler flue cleaning device, comprising a transmission module, a control module, a dust collection module and a driven module, wherein each module adopts at least one arbitrary combination, and all modules are coaxially connected in a straight line, with the dust collection module located at the front end; the dust collection module is equipped with a brush head drive motor, the output shaft of which extends out of the outer shell and is connected to the rotating brush head through a self-lubricating copper sleeve, the diameter of the rotating brush head being greater than or equal to the inner diameter of the boiler flue.

[0005] The transmission module includes a moving wheel, a bevel gear set, a spline shaft, and a bidirectional motor. The bidirectional motor is located on one side of the housing. The output shaft of the bidirectional motor is connected to one gear of the bevel gear set. The other gear of the bevel gear set is coaxially arranged with the spline shaft. The two ends of the spline shaft are supported on the other side of the housing by bearings. The moving wheel is fixedly connected to the two ends of the spline shaft respectively.

[0006] The driven module includes a moving wheel and a driven shaft. The two ends of the driven shaft are supported by bearings at the corresponding housings, and the moving wheel is connected to the two ends of the driven shaft.

[0007] A pre-tensioning mechanism is provided between two movable wheels in the same housing. The pre-tensioning mechanism includes a positioning frame, a spring frame, a pre-tensioning torsion spring, and a pre-tensioning wheel. The positioning frame has a U-shaped groove structure and is positioned between the two movable wheels. One end of the spring frame is connected to the positioning frame by a pin, and the other end of the positioning frame is connected to the pre-tensioning wheel by a pin. An upper baffle is provided at the upper end of the positioning frame. A pre-tensioning torsion spring is coaxially mounted on the pin connected to the positioning frame. One end of the pre-tensioning torsion spring is supported on the positioning frame, and the other end is supported on the upper baffle.

[0008] The radial section of the movable wheel is trapezoidal, the diameter of the outer end face is smaller than the diameter of the inner end face, and the outer circumference of the movable wheel is made of patterned rubber material.

[0009] The control module includes a central controller, which controls the electrical components within each module via wired or wireless means; a power supply battery is located on one side of the central controller and is connected to the power source of the central controller.

[0011] The dust collection module includes a turbine dust collector, a labyrinth sealing ring, and a filter.

On the other side of the housing, there are two dust collection ports, one above the other, with a labyrinth sealing ring at each port. The outlet of the labyrinth sealing ring corresponds to the position of the filter.

[0012] The bristles of the rotating brush head are arranged in a spiral structure, and the diameter of the rotating brush head is 1-2 mm larger than the inner diameter of the boiler flue pipe.

[0013] Each module has a cylindrical or polygonal shell; adjacent modules are positioned by insertion or threaded connection at their end faces.

[0014] The modular small boiler flue gas tube cleaning device of this application adopts the above structure and has the following advantages: 1. Depending on the working environment and work content, different numbers of transmission modules, control modules, dust collection modules and driven modules can be selected, and their positions can be planned arbitrarily to ensure the overall support strength and moving speed of the device; 2. The modules adopt a hexagonal plug-in structure, which not only facilitates the connection between modules, but also makes it more suitable for repositioning and easier to use; 3. The moving wheels adopt a trapezoidal structure with a small outer end diameter and a large inner end diameter, which increases the contact area with the pipe wall and makes them more suitable for moving in the pipeline. In addition, a pre-tightening wheel structure is adopted to ensure that the moving wheels are in close contact with the pipe wall during the movement of the whole device, preventing shaking.

[0022] like Figures 1 to 4 As shown, a modular small boiler flue dust removal device consists of a transmission module 1, a control module 2, a dust collection module 3, and a driven module 4. Each module uses at least one arbitrary combination, and all modules are coaxially arranged in a straight line, with the dust removal module 5 located at the front end. The outer shell 6 of each module is a cylindrical or polygonal structure. The end faces of adjacent modules are inserted for positioning or threaded connection. In this embodiment, the outer shell 6 of each module is a cylindrical structure, and the end faces of adjacent modules are provided with hexagonal slots and hexagonal buckles. The hexagonal buckles and hexagonal slots are inserted and matched. To ensure the connection strength of adjacent modules, bolts or other secondary connection and positioning are set at adjacent positions at the insertion point. The dust removal module is equipped with a brush head drive motor 501. The output shaft of the brush head drive motor 501 extends out of the outer shell 6 and is connected to a rotating brush head 503 through a self-lubricating copper sleeve 502. The bristles of the rotating brush head 503 are arranged in a spiral structure, and the diameter of the rotating brush head 503 is 1-2 mm larger than the inner diameter of the boiler flue. Each module in this device has an independent function and can be combined arbitrarily according to actual needs to complete the purposes of movement, dust removal, vacuuming, lighting and monitoring inside the flue, thereby ensuring the efficiency and quality of dust removal.

[0023] The transmission module 1 includes a moving wheel 7, a bevel gear set 102, a splined shaft 103, and a bidirectional motor 104. The bidirectional motor 104 is located on one side of the housing 6. The output shaft of the bidirectional motor 104 is connected to one gear of the bevel gear set 102. The other gear of the bevel gear set 102 is coaxially arranged with the splined shaft 103. The two ends of the splined shaft 103 are supported on the other side of the housing 6 by bearings. The moving wheel 7 is fixedly connected to both ends of the splined shaft 103. The transmission module 1 is the main power source of this device. The power of the bidirectional motor 104 is reversed through the bevel gear set 102 and transmitted to the moving wheel 7.

[0024] The driven module 4 includes a movable wheel 7 and a driven shaft 402. The driven shaft 402 is supported at both ends by bearings at the corresponding housings, and the movable wheel 7 is connected to both ends of the driven shaft 402. The driven module 4 does not contain a motor and is used in conjunction with the transmission module 1.

[0025] A pre-tensioning mechanism is provided between the two movable wheels 7 on the same housing 6, such as Figure 6 and Figure 7 As shown, the pre-tensioning mechanism includes a positioning frame 105, a spring frame 106, a pre-tensioning torsion spring 107, and a pre-tensioning wheel 108. The positioning frame 105 has a U-shaped groove structure and is positioned between two movable wheels 7. One end of the spring frame 106 is connected to the positioning frame 105 via a pin, and the other end of the positioning frame 105 is connected to the pre-tensioning wheel 108 via a pin. An upper baffle 109 is provided at the upper end of the positioning frame 105. The pre-tensioning torsion spring 107 is coaxially mounted on the pin connected to the positioning frame 105. One end of the pre-tensioning torsion spring 107 is supported on the positioning frame 105, and the other end is supported on the upper baffle 109. The radial cross-section of the movable wheel 7 is trapezoidal, the outer end diameter is smaller than the inner end diameter, and the outer circumference of the movable wheel 7 is made of patterned rubber. The pre-tensioning wheel 108 is supported on the inner wall of the flue pipe by the pre-tensioning torsion spring 107, which also causes the two movable wheels 7 on both sides to be completely flush against the inner wall of the flue pipe, thereby preventing the overall device from shaking during operation. Furthermore, with the adjustment of the pre-tensioning torsion spring 107, even if the pipe wall is uneven, the overall device can still operate smoothly. This pre-tensioning mechanism is used in conjunction with the movable wheels 7 and can be added or removed according to the internal conditions of the pipe.

[0026] The control module 2 includes a central controller 201, which controls the electrical components within each module via wired or wireless means. A power supply battery 203 is located on one side of the central controller 201 and is connected to its power source. The central controller 201 can control the start and stop of the brush head drive motor 501, the bidirectional motor 104, the turbine vacuum fan 301, and the lighting or camera 202. The power supply battery 203 provides power to the brush head drive motor 501, the bidirectional motor 104, the turbine vacuum fan 301, and the lighting or camera 202.

[0027] The control module 2 has a housing 6 equipped with a lighting and camera 202 facing the rotating brush head 503; and the power and data cables of the lighting and camera 202 are connected to the central controller 201. Users can use the lighting to illuminate the inside of the flue and the camera to capture images inside the flue to determine the cleaning effect on the pipe wall, according to their actual needs.

[0028] The vacuuming module 3 includes a turbine vacuum fan 301, a labyrinth sealing ring 302, and a filter 303. The turbine vacuum fan 301 is located inside one side of the housing 6, and its inner end is connected to the filter 303 via a quick-release clamp 304. On the other side of the housing 6, there are two suction ports 305, one above the other, each with a labyrinth sealing ring 302. The outlet of the labyrinth sealing ring 302 corresponds to the position of the filter 303. The labyrinth sealing ring 302 prevents interference between the two suction ports 305. Figure 5 As shown, the dust inlet paths of the upper and lower dust inlets 305 are different, thereby improving dust collection efficiency.
