DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Example: See Figures 1 to 5 According to an embodiment of the utility model, a technical solution is provided: a convenient-to-operate cleaning device for a thermal power plant boiler, comprising a support frame 1, which provides basic support for the device and is fixed at a corresponding position of the thermal power plant boiler; a motor 2, which is installed at the bottom of the support frame 1 and is used to drive an output disk 3 to rotate; the output disk 3 is fixed at the output end of the motor 2 as a transmission structure, a connecting column 4, a component connecting a locking sleeve 5, the locking sleeve 5 is used to fix the position of a cleaning brush 8 for cleaning operations, a connecting hole 6 and a limiting column 7, which are used to install the cleaning brush 8, a limiting hole 9 and a steel ball 10, and a limiting groove 11 is provided on one end of the limiting column 7 inserted into the connecting hole 6, which is adapted to the steel ball 10 and is used to ensure that the locking sleeve 5 slides so that the steel ball 10 is clamped and fixed to the limiting column 7.

[0028] The easy-to-operate cleaning device for thermal power plant boilers adopts the above-mentioned structure. The limiting column 7 fixed with the cleaning brush 8 is inserted into the connecting hole 6, and then the steel ball 10 is embedded in the limiting groove 11 on the limiting column 7 from the connecting hole 6 by sliding the locking sleeve 5, so that the limiting column 7 is fixed in the connecting hole 6. When disassembly is required, the locking sleeve 5 is slid so that the locking sleeve 5 does not abut against the steel ball 10, and the limiting column 7 fixed with the cleaning brush 8 is pulled out, thereby realizing rapid installation and disassembly, thereby solving the problem that the cleaning device for thermal power plant boilers in the prior art is prone to wear at the end of the cleaning brush 8 that contacts the boiler wall due to long-term use and other reasons, and it is more troublesome to replace it after wear.

[0029] In this embodiment, a locking mechanism 12 is also included, which is a key component for ensuring that the locking sleeve 5 can be stably fixed on the connecting column 4 when needed. A locking ring 121 is fixed on the outer wall of the connecting column 4. As the main component of the locking mechanism 12, a spring 122 is installed between the locking ring 121 and the locking sleeve 5 to provide restoring force and stability. The locking ring 121 is fixed inside the locking sleeve 5 and interacts with the locking ring 121 to provide a locking force during the dust cleaning operation. In the process of the motor 2 driving the multiple connecting columns 4 on the output disk 3 to rotate, the locking sleeve 5 slides back and forth on the connecting column 4, causing the limit column 7 to lift the steel ball 10, thereby causing the cleaning brush 8 to fall off. By providing the locking ring 121, the spring 122 and the pushing protrusion 13, the spring 122 continuously resists the locking ring 121 and the pushing protrusion 13, so that the locking sleeve 5 can relatively stably resist the steel ball 10 to prevent the cleaning brush 8 from falling off.

[0030] In this embodiment, the concave inclined surface 14 is used to stabilize the movement of the steel ball 10. By providing the concave inclined surface 14, the push protrusion 13 can be reduced from directly abutting against the steel ball 10, thereby reducing the wear of the steel ball 10 or the push protrusion 13 and increasing the service life.

[0031] In this embodiment, the limit ring 15 is a fixed part on the connecting column 4, and its main function is to limit the movement range of the locking sleeve 5 on the connecting column 4 to ensure that the locking sleeve 5 does not fall off the connecting column 4 during the cleaning operation. By setting the limit ring 15, it is prevented that when the motor 2 drives the output disk 3 to rotate, the locking sleeve 5 slidingly connected to the connecting column 4 does not move too much, thereby preventing the locking sleeve 5 from effectively locking the steel ball 10.

[0032] In this embodiment, a plurality of rubber rings 16 are fixedly provided on the outer wall of the locking sleeve 5 at intervals. By providing the rubber rings 16, the gripping force of the maintenance personnel's hands on the locking sleeve 5 is increased, thereby preventing the maintenance personnel's hands from slipping during the replacement process.

[0033] In this embodiment, an electric push rod 17 is also included, which is fixed on the top of the support frame 1 and connected to the top of the support frame 18. The output end provides force to move the support frame 18. The support frame 18 is a framework structure used to support other components. The electric push rod 17 drives the support frame 18 to move up and down, thereby driving the electric and multiple cleaning brushes 8 connected to the output disk 3 to move up and down, so that the inner wall of the boiler can be cleaned evenly and the cleaning range can be increased.

[0034] In this embodiment, the limit rod 20 is used to limit the moving range of the support frame 18 in the vertical direction. The height of the limit rod 20 is greater than the height of the motor 2. By setting the limit rod 20 and making the height of the limit rod 20 greater than the height of the motor 2, it is prevented that the bottom of the support frame 1 is against the body of the motor 2 during the process of the electric push rod 17 pushing the support frame 18, causing damage to the body of the motor 2.

[0035] Working principle: During use, the motor 2 fixed at the bottom of the support frame 18 drives the output disk 3 to rotate, thereby rotating the connecting column 4 fixed to the rotating disk, and then driving the cleaning brush 8 to rotate to clean the inner wall of the boiler. During the cleaning process, the electric push rod 17 drives the support frame 18 to move up and down, thereby moving the motor 2, the output disk 3 and the cleaning brush 8 fixed at the bottom of the support frame 18, thereby increasing the cleaning range, and by providing a limit ring 15, it can prevent the locking sleeve 5 from excessively moving and causing the cleaning brush 8 to fall off;

[0036] When the cleaning brush 8 needs to be replaced, the maintenance personnel grasps the locking sleeve 5 with their hands and moves it toward the output disk 3 so that the pushing protrusion 13 does not abut against the steel ball 10. At this time, the maintenance personnel grasps the limiting column 7 with their other hands and pulls it out of the connecting hole 6. Under the influence of the force, the steel ball 10 stuck in the limiting groove 11 is pushed up by the limiting column 7. At this time, the steel ball 10 cannot limit the limiting column 7, and the maintenance personnel can take out the cleaning brush 8 more easily. When it needs to be installed, the maintenance personnel only needs to remove the limiting column 7 fixed on the cleaning brush 8. Inserted into the connecting hole 6, the spring 122 located between the locking ring 121 and the pushing protrusion 13 drives the locking sleeve 5 to move toward the cleaning brush 8. At the same time, the concave inclined surface 14 located on one side of the pushing protrusion 13 steadily pushes the steel ball 10 into the limiting groove 11 on the limiting column 7, so that the steel ball 10 is stuck in the limiting column 7, thereby completing the quick installation, solving the problem that the cleaning device for the thermal power plant boiler in the prior art is prone to wear at the end that contacts the boiler wall due to long-term use and other reasons, and it is more troublesome to replace after wear.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
