[0046] The bottom wall cleaning mechanism 4 relies on the extension and retraction of the vertical telescopic member to drive the bottom cleaner to approach or move away from the bottom side wall in the internal space to be cleaned during operation, so as to achieve the purpose of reasonably cleaning the scale.

[0047] Preferably in any of the above solutions, the vertical telescopic member comprises two vertically spaced vertical telescopic cylinders 402, the bottom end of each vertical telescopic cylinder 402 is fixed to the top of the bottom connecting seat 209, the lower end of each vertical telescopic cylinder 402 is fixed to the top of the bottom cleaner, and the two vertical telescopic cylinders 402 are in synchronous extension and retraction state during operation.

[0050] Specific working principle: the scale cleaning device of the steam production equipment 5 is driven by an external mechanical hand to realize overall displacement on demand in use, and can rely on the displacement frame 1 to drive the linkage reverser 2 and the side wall cleaning mechanism 3 and the bottom wall cleaning mechanism 4 on it to move.

[0051] Specifically, the bottom wall cleaning mechanism 4 can be made to abut against the inner wall bottom of the steam production equipment 5 downward and clean the scale on the bottom during movement as needed.

[0052] In addition, the side wall cleaning mechanism 3 can also be controlled to displace leftward or rightward as needed to realize brushing of the scale on the inner side wall of the steam production equipment 5 after soaking in the descaling agent, and to spray cleaning water to the working position as needed during the working of the scale cleaning device of the steam production equipment 5.

[0053] When the whole inner wall of the steam production equipment 5 needs to be cleaned, the whole device is still controlled by the existing mechanical hand. When the linkage reversing device 2 works, the center shaft 204 is used as the power input. When the center shaft 204 rotates, the two side bevel gears 206 on both sides can be driven by the total drive bevel gear 205 to drive the side wall cleaning mechanism 3. When the side wall cleaning mechanism 3 works, the inner wall of the steam production equipment 5 is cleaned. In addition, since the bottom of the center shaft 204 is connected with the bottom connecting seat 209, when the bottom connecting seat 209 rotates, the bottom wall cleaning mechanism 4 can be driven to work, so as to clean the bottom wall of the steam production equipment 5. Specifically, the side cleaner mainly relies on the rotation of the side bevel gear 206 to drive the side connecting seat 208 to rotate. In the process of rotating the side connecting seat 208, the two side telescopic cylinders 7 rotate synchronously, and the side rotating disc 8 connected with the side telescopic cylinder 7 rotates synchronously. In the process of rotating the side rotating disc 8, the side cleaning brush 9 on the outer end surface rotates synchronously. Since the working end of the side cleaning brush 9 directly abuts on the corresponding inner wall to clean the scale, the rotating brush can quickly remove the scale. Pre-soaking the scale with a descaling agent can reduce the difficulty of scale cleaning. In addition, the bottom cleaner mainly relies on the rotation of the center shaft 204 to drive the bottom rotating disc 403 to rotate. In the process of rotating the bottom rotating disc 403, the two vertical telescopic cylinders 402 rotate synchronously, and the bottom rotating disc 403 connected with the vertical telescopic cylinder 402 rotates synchronously. In the process of rotating the bottom rotating disc 403, the side bottom cleaning brush 401 on the bottom rotates synchronously. Since the working end of the bottom cleaning brush 401 directly abuts on the corresponding bottom wall to clean the scale, the rotating brush can quickly remove the scale on the bottom wall.

[0054] In conclusion, the scale cleaning device of the steam production equipment 5 can realize rapid brushing and cleaning of the side wall scale and the bottom scale after the descaling agent immersion when cleaning the scale in the steam production equipment 5, and the overall cleaning effect is comprehensive and efficient; the side wall cleaning mechanism 3 and the bottom wall cleaning mechanism 4 adopt a single driving element to realize multidirectional output linkage when working, which can better guarantee the linkage effect when cleaning, and guarantee the comprehensiveness of cleaning; the side wall cleaning mechanism 3 and the bottom wall cleaning mechanism 4 can complete lateral adjustment according to the size of the current internal space when cleaning the scale in the steam production equipment 5, thereby achieving lateral telescopic positioning of the internal space of different sizes, and achieving the purpose of close cleaning. The lateral cleaning brush 9 and the auxiliary cleaning brush 10 arranged on the lateral rotating disc 8 can realize rapid brushing of the bottom corner part of the internal space when working, effectively guaranteeing the rapid cleaning treatment of the scale after the descaling agent immersion.
