The high-efficiency thermal power generation device according to claim 1, characterized in that: The inner wall of the connecting ring (605) is provided with a locking block, and the locking block is located in the spiral groove on the circumferential surface of the combustion chamber (6). The arc-shaped scraper (606) is in contact with the outer wall of the combustion chamber (6).

3. The high-efficiency thermal power generation device according to claim 2, characterized in that: The stop block (703) is in contact with the push plate (701), and the hammer (707) is in contact with the groove on the circumferential surface of the combustion chamber (6).

4. A method for operating a high-efficiency thermal power generation device, employing the high-efficiency thermal power generation device as described in claim 3, characterized in that: Includes the following steps: Step 1: Device operation. Solid fuel is added to the feed inlet (401). As the blower (3) runs, the central shaft of the blower (3) rotates, which drives the rotating shaft (403) to rotate via the belt (404). The rotation of the rotating shaft (403) drives the fixed disk (408) to rotate. Step 2: The rotation of the fixed disk (408) drives the cutter head (405) to rotate, which crushes the added solid fuel. After crushing, the surface area of ​​the fuel particles increases, and they come into more full contact with oxygen, thus accelerating the combustion reaction rate. The rotation of the fixed disk (408) also drives the concave block (406) to rotate. Step 3: The concave block 1 (406) rotates and drives the concave block 2 (407) that it cooperates with to rotate through the surface groove. Since the concave block 1 (406) is limited by the positioning post (411) and can only move along the direction of the positioning post (411), the movement of the concave block 1 (406) drives the grinding disc (409) to move and compress the reset spring (410). Step 4: Under the force of the reset spring (410), the moving grinding disc (409) moves back and forth with the rotation of the concave block (406). The reciprocating movement of the moving grinding disc (409) causes the material crushed on the inner wall to be constantly turned over, preventing solid fuel from getting stuck between the various cutter heads (405). It can also increase the contact rate between the granular fuel and the cutter head (405) by turning over, greatly improving the crushing effect. The crushed fuel is blown into the combustion chamber (6) by the air blown out by the blower (3) through the discharge port and is ignited by the burner for combustion and heating.
