[0002] A thermal power plant, abbreviated as "thermal power," is a factory that produces electricity using combustible materials as fuel. Boilers are one of the main pieces of equipment, and coal drop pipes are widely used to supply coal.

[0003] When a coal drop pipe is in use, some of the coal lumps will adhere to the inner wall of the coal drop pipe during the process of transporting the coal lumps in the coal drop pipe, thereby reducing the coal transport space of the coal drop pipe and making the coal drop pipe prone to blockage. When a blockage occurs, the coal lumps stuck in the coal drop pipe are generally shaken off by manual hammering or vibration using a vibrator.

[0004] However, this method of draining requires manual labor, which is time-consuming and labor-intensive, and it is difficult to perform multi-directional vibration drainage on a clogged coal drop pipe. Summary of the Invention

Obviously, the drawings used in the following description only relate to some embodiments of the present invention and are not intended to limit the present invention. In the drawings, [Figure 1] 1 is a schematic diagram showing the overall structure of the present invention; [Figure 2] FIG. 2 is a side view showing the transmission mechanism of the present invention. [Figure 3] 1 is a schematic view of a support component of the present invention; [Figure 4] 1 is a schematic view of a rotating component of the present invention; DETAILED DESCRIPTION OF THE INVENTION

[0016] In order to enable those skilled in the art to better understand the present invention, the following will describe the present invention in more detail in combination with specific embodiments and drawings.

[0017] The terms used in this specification are general terms currently widely used in the art, taking into consideration the functions of the specification. However, these terms may be changed according to the intentions of those skilled in the art, existing practices, or the development of new technologies in the art. Furthermore, specific terms may be selected by the applicant, and in this case, their detailed meanings will be described in the detailed description of the specification. Therefore, the terms used in this specification should not be understood as simple names, but should be understood based on the meaning of the terms and the overall description of the specification.

[0018] Referring to FIGS. 1 to 4, this embodiment 1 coal drop tube; a permeation mechanism 2 including a power part 21 attached inside the coal drop pipe 1, a striking part 22 attached outside the power part 21, a limit part 24 provided outside the striking part 22, and a rotating part 25 attached outside the limit part 24; The power part 21 rotates the striking part 22 inside the limit part 24, so that the striking part 22 strikes the coal drop pipe 1; The rotating part 25 can realize differential rotation between the limit part 24 and the striking part 22, providing a cleaning device for the coal drop pipe of the boiler.

[0019] When the coal lumps enter from the inlet, they move along the coal drop pipe 1, and in the process, some of the coal lumps adhere to the inner wall of the coal drop pipe 1.

[0020] In use, the striking element 22 is installed inside the limit element 24. When the power element 21 rotates the striking element 22, the striking element 22 cooperates with the limit element 24, allowing the striking element 22 to strike the inner wall of the coal drop pipe 1, causing the inner wall of the coal drop pipe 1 to vibrate and shake off the adhering coal lumps, thereby realizing the effect of opening the coal drop pipe 1.

[0021] The power element 21 rotates the striking element 22, and at the same time, the limit element 24 can be rotated via the rotating element 25. The limit element 24 and the striking element 22 rotate in different directions and at different speeds. Therefore, when the striking element 22 and the limit element 24 work together to strike the coal drop pipe 1, the coal drop pipe 1 can be struck in all directions, thereby realizing omnidirectional vibration permeation and improving the permeation efficiency and permeation effect.

[0022] As an example provided by the present application, as shown in Figures 1 and 2, the power component 21 includes a motor 211 mounted inside the coal drop pipe 1 and a rotating shaft 212 fixedly connected to the output shaft of the motor 211.

[0023] The striking part 22 includes a connecting rope 221 and a striking block 222. Both ends of the connecting rope 221 are fixedly connected to the rotating shaft 212 and the striking block 222, respectively.

[0024] The connecting rope 221 is made of a flexible material, and the striking block 222 is made of a rubber material.

[0025] In use, when the motor 211 is started, the motor 211 rotates the rotating shaft 212, which rotates the connecting rope 221 and the striking block 222.

[0026] As shown in FIG. 2, since the connecting rope 221 is made of a flexible material, when the connecting rope 221 and the striking block 222 rotate, under the action of centrifugal force, the connecting rope 221 and the striking block 222 can approach the inner wall of the coal drop pipe 1.

[0027] As an embodiment provided by the present application, as shown in FIGS. 1 to 3, the drainage mechanism 2 further includes a support part 23 attached to the inside of the coal drop pipe 1, The support part 23 includes a mounting ring 231, a support rod 232, and a support ring 233. The mounting ring 231 is fixedly connected to the inside of the coal drop pipe 1, and both ends of the support rod 232 are fixedly connected to the mounting ring 231 and the support ring 233 respectively.

[0028] The limit component 24 includes a sleeve 241 rotatably connected to the outside of the support ring 233 , and a recessed groove 242 provided inside the sleeve 241 .

[0029] In use, as shown in FIG. 2, the connecting rope 221 passes through the sleeve 241, and when the motor 211 rotates the connecting rope 221 and the striking block 222 via the rotating shaft 212, under the action of centrifugal force, the connecting rope 221 and the striking block 222 approach the inner wall of the coal drop pipe 1, and the connecting rope 221 is blocked by the sleeve 241 and comes into close contact with the end face of the sleeve 241.

[0030] As an embodiment provided by the present application, as shown in FIGS. 1 to 4 , the rotating part 25 includes a toothed ring 251 fixedly connected to the outside of the sleeve 241, a bottom plate 252 fixedly connected to the outside of the toothed ring 251, a driving gear 253 fixedly connected to the outside of the rotating shaft 212, and a driven gear 254 rotatably connected to the outside of the bottom plate 252, The drive gear 253 and the driven gear 254 mesh with each other, the driven gear 254 and the toothed ring 251 mesh with each other, and the rotation shaft 212 is rotatably connected to the outside of the bottom plate 252 .

[0031] In use, as shown in FIG. 4, when the motor 211 rotates the rotating shaft 212 clockwise, the rotating shaft 212 rotates the driving gear 253 clockwise, which in turn rotates the driven gear 254 counterclockwise, which in turn rotates the toothed ring 251 counterclockwise, and the rotational angular velocity of the rotating shaft 212 is greater than the rotational angular velocity of the toothed ring 251.

[0032] When the toothed ring 251 rotates counterclockwise, the sleeve 241 can be rotated counterclockwise synchronously.

[0033] As an embodiment provided by the present application, as shown in FIGS. 1 to 4, when the connecting rope 221 contacts the groove 242, the striking block 222 can contact the coal drop pipe 1; If the connecting rope 221 does not contact the groove 242 , the striking block 222 cannot contact the coal drop pipe 1 .

[0034] In use, the motor 211 rotates the rotating shaft 212, which in turn rotates the connecting rope 221 and the striking block 222 in the same direction.

[0035] As shown in FIG. 2, the connecting rope 221 is blocked by the sleeve 241 and comes into close contact with the end surface of the sleeve 241. Therefore, if the connecting rope 221 does not come into contact with the groove 242, the striking block 222 is limited by the length of the connecting rope 221 and cannot come into contact with the coal drop pipe 1.

[0036] When the connecting rope 221 rotates and enters the groove 242, under the action of centrifugal force, the connecting rope 221 comes into contact with the edge of the groove 242, and the striking block 222 can quickly come into contact with and collide with the inner wall of the coal drop pipe 1, causing the coal drop pipe 1 to vibrate due to the collision, and the attached coal lumps will detach from the inner wall of the coal drop pipe 1 under the vibration action, thereby realizing the permeability effect of the coal drop pipe 1.

[0037] As the rotating shaft 212 continues to rotate, the connecting rope 221 is released from the groove 242 and the striking block 222 is separated from the inner wall of the coal drop pipe 1 .

[0038] When the rotating shaft 212 continues to rotate and causes the connecting rope 221 to contact the groove 242, the striking block 222 can strike the inner wall of the coal drop pipe 1 again. As a result, during the continuous rotation of the rotating shaft 212, the striking block 222 can repeatedly strike the inner wall of the coal drop pipe 1, thereby causing the coal drop pipe 1 to vibrate continuously. When the coal lump is completely shaken off, the motor 211 can be stopped.

[0039] It should be noted that when the motor 211 rotates the rotating shaft 212, the rotating shaft 212 rotates the toothed ring 251 in the opposite direction via the driving gear 253 and the driven gear 254, i.e., when the connecting rope 221 and the striking block 222 rotate in the same direction as the rotating shaft 212, the toothed ring 251 rotates the sleeve 241 in the opposite direction.

[0040] As the sleeve 241 rotates in the opposite direction, the position of the groove 242 also changes in real time, and when the connecting rope 221 and the striking block 222 rotate in the same direction as the rotating shaft 212, the striking position of the coal drop pipe 1 also changes, thereby realizing multi-directional striking collision with the coal drop pipe 1, so as to vibrate the stuck coal lumps more comprehensively and penetrate the coal drop pipe 1 more thoroughly and comprehensively.

[0041] Furthermore, since the rotation direction of the connecting rope 221 and the striking block 222 is opposite to the rotation direction of the sleeve 241, the frequency with which the striking block 222 strikes and collides with the coal drop pipe 1 can be increased, thereby improving the permeation effect and permeation efficiency.

[0042] From the above, the mutual cooperation of the power part 21, the striking part 22, the support part 23 and the limit part 24 enables the striking block 222 to frequently strike and collide with the coal drop pipe 1, thereby vibrating the coal drop pipe 1 and shaking off the coal lumps adhering thereto; furthermore, by installing the rotating part 25, the striking position can be made more comprehensive, the striking efficiency can be improved, and a fast and efficient permeation effect can be achieved.

[0043] Finally, it should be pointed out that the methods and apparatus described in detail above are merely examples, and that those skilled in the art can make many modifications to these examples without departing from the scope of the present invention.
