[0019] Specifically, the switching assembly includes a bidirectional telescopic rod 24, a bidirectional telescopic rod 26, a connecting block 27, a connecting block 28, two moving grooves 23 are oppositely arranged below the connecting column 15, the bidirectional telescopic rod 24 is fixedly arranged at the middle position inside the moving groove 23, the connecting block 27 is fixedly arranged at the telescopic end of the bidirectional telescopic rod 24, two moving grooves 25 are oppositely arranged below the connecting column 15, the bidirectional telescopic rod 26 is fixedly arranged at the middle position inside the moving groove 25, the connecting block 28 is fixedly arranged at the telescopic end of the bidirectional telescopic rod 26, the arc-shaped block 29 and the arc-shaped block 210 are fixedly arranged below the connecting block 27 and the connecting block 28, the inner side of the arc-shaped block 29 and the arc-shaped block 210 is provided with a tooth, the upper end of the rotating column 20 is provided with a tooth groove, and the upper end of the sleeve 21 is provided with a tooth groove.

[0021] Specifically, the cleaning assembly includes a connecting plate 211 and a scraping plate 212, the connecting plate 211 is fixedly connected to the outer periphery of the rotating column 20, one end of the connecting plate 211 is fixedly connected with the scraping plate 212, the side surface of the scraping plate 212 is arc-shaped design, and is tightly attached to the inner wall of the shell 10, and the side surface of the scraping plate 212 is chamfered.

The extension length of the bidirectional telescopic rod two 26 is less than the distance from the arc-shaped block two 210 to the arc-shaped block one 29, ensuring that the arc-shaped block one 29 and the arc-shaped block two 210 can be engaged with the rotating column 20 and the sleeve 21 in the preset order and position during the switching process, avoiding the jamming or failure caused by the engagement of the two arc-shaped blocks with the rotating column 20 or the sleeve 21 at the same time, and improving the reliability and stability of the switching assembly. In addition, this length limitation also provides convenience for the maintenance and repair of the equipment. Maintenance personnel can more conveniently observe and operate the switching assembly, discover and solve potential problems in time, reduce the maintenance difficulty and cost of the equipment, and prolong the service life of the equipment.

[0025] Specifically, the upper surface of the upper cover 11 is provided with an inlet 13, and the inlet 13 penetrates through the upper cover 11. The side surface of the shell 10 is provided with an outlet 14, and the outlet 14 penetrates through the inside of the shell 10.

[0026] In this embodiment, the inlet 13 provided on the upper surface of the cover 11 provides a convenient channel for the input of materials or media into the boiler. All materials or media can smoothly enter the boiler through the inlet 13, ensuring that the boiler can operate continuously and stably to meet the needs of production or use. The outlet 14 provided on the side of the outer shell 10 provides an effective way to discharge steam or other output media generated inside the boiler. After the heating and other processes are completed inside the boiler, the media can be discharged in a timely and stable manner through the outlet 14, avoiding excessive pressure or other safety hazards caused by the accumulation of media inside the boiler.

[0027] In the solar boiler combined with medium-temperature steam system, a solar photovoltaic-assisted heating steam boiler operates in conjunction with the solar collector to receive and convert solar energy into thermal energy from heat transfer oil. The high-temperature heat transfer oil is mixed in a heat storage tank and then flows through a circulation pipeline to the boiler and steam generator, causing water to generate steam. Based on the unstable solar radiation and the factory's parameter requirements, the system is equipped with multiple sensors connected to the controller system in the pipeline. When there is sufficient sunlight, the heat storage tank stores energy. At night or when there is insufficient radiation, the temperature detector senses a low temperature and closes the valve at outlet 14. The medium is heated by the heating rod 22 in the boiler. After reaching the standard, it flows out through outlet 14, ensuring that the system outputs steam stably to meet the factory's heat needs.

[0028] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
