[0023] The principles and features of the present utility model will be described below with reference to the drawings. The examples given are only used to explain the present utility model and do not limit the scope of use of the present utility model.

[0024] As Figures 1-3 shown, the present utility model provides an air preheater soot blower for an energy power plant, which includes a housing 2, a sound wave generator and a sound transmission pipe 1. The sound wave generator is installed inside the housing 2. The upper end of the sound transmission pipe 1 is connected to the air preheater through a flange, and the lower end is concentrically and fixedly connected with an annular connecting plate 11. The connecting plate 11 is horizontally arranged coaxially above the opening of the housing 2. Wherein, a placement groove 23 is provided at the opening above the housing 2, and the connecting plate 11 is placed in the placement groove 23, so as to limit the connecting plate 11 to a certain extent and avoid the horizontal shaking of the connecting plate 11 from affecting the installation stability of the sound transmission pipe 1.

[0025] Two movable pressure rods 3 are vertically arranged around the outer wall of the housing 2. The middle part of the movable pressure rod 3 is hinged on the hinge seat 21 on the outer wall of the housing 2. A crimping part 30 is arranged at the upper end of the movable pressure rod 3. By swinging the movable pressure rod 3, the crimping part 30 can be pressed against the edge of the top surface of the connecting plate 11, so as to effectively fix the connecting plate 11 in the placement groove 23. A second spring 31 is installed between the upper end of the movable pressure rod 3 and the side wall of the housing 2. During maintenance, only the abutting and fixing of the lower end of the movable pressure rod 3 needs to be released. Under the action of the elastic force of the second spring 31, the movable pressure rod 3 will swing around the middle hinge point, so that the upper end crimping part 30 moves away from the connecting plate 11, and then the fixing of the connecting plate 11 can be released, and the connecting plate 11 and the sound transmission pipe 1 can be easily removed, making the disassembly of the sound transmission pipe 1 more convenient. At this time, the upper part inside the housing 2 can be exposed, which is convenient for maintaining the upper part of the sound wave generator.

[0026] A base 4 is inserted at the bottom opening of the housing 2. A turntable 6 is horizontally arranged inside the base 4. The turntable 6 includes two staggered and eccentric semi - circles. Among them, the base 4 includes a bottom plate 41 and a cylinder body 42. The cylinder body 42 is coaxially fixed above the bottom plate 41. The cylinder body 42 can be inserted upward into the bottom opening of the housing 2. The diameter of the bottom plate 41 is larger than the diameter of the bottom opening of the housing 2 for limit support. The turntable 6 is horizontally arranged in the middle of the cylinder body 42. A rotating shaft 61 (61) is fixed at the center of the turntable 6. The lower end of the rotating shaft 61 (61) is rotatably installed on the bottom plate 41 and extends out of the bottom plate 41. An adjusting part 611 is arranged at the end of the rotating shaft 61 (61) extending out of the bottom plate 41. The adjusting part 611 is an internal hexagonal slot hole, which is arranged on the lower end surface of the rotating shaft 61 (61). By inserting a corresponding wrench into the internal hexagonal slot hole, the rotating shaft 61 (61) and the turntable 6 can be driven to rotate, making the rotation adjustment of the turntable 6 more convenient.

[0027] First through - holes 40 are horizontally opened on the left and right side walls of the cylinder body 42 of the base 4. Second through - holes 20 are horizontally correspondingly opened on the side wall of the housing 2. A plug rod 51 is movably arranged in the first through - hole 40. One end of the plug rod 51 movably penetrates through the first through - hole 40 and the second through - hole 20 and extends outwards to abut against the lower end of the movable pressure rod 3, and the other end abuts against the outer edges of the two semi - circles of the turntable 6. Among them, a limiting block 52 is fixed on the plug rod 51 in the first through - hole 40. The diameter of the limiting block 52 is larger than the opening diameters at both ends of the first through - hole 40, so that the limiting block 52 can effectively limit the movement of the plug rod 51. A first spring 53 is sleeved on the plug rod 51. The two ends of the first spring 53 respectively abut against the limiting block 52 and the inner wall of the opening of the first through - hole 40 close to the turntable 6. Among them, the moving distance of the limiting block 52 in the first through - hole 40 is much larger than the sum of the length of the outer end of the plug rod 51 extending outwards and the inner wall thickness of the housing 2, so that the outer end of the plug rod 51 can completely retract into the first through - hole 40 from outside the housing 2 through the second through - hole 20.

[0028] A positioning block 43 is fixedly provided on the outer wall of the cylinder body 42, and a positioning groove 22 matching with the positioning block 43 is provided on the inner wall of the lower opening of the housing 2. Through the cooperation of the positioning block 43 and the positioning groove 22, the installation position of the base 4 below the housing 2 can be effectively positioned, so that the insertion rod 51 can be aligned with the two through holes for installation, improving the installation convenience.

[0029] When only the upper connection plate and the sound transmission pipe 1 need to be disassembled, when the adjusting part 611 drives the rotating shaft 6161 and the turntable 6 to rotate, under the elastic force of the first spring 53, the inner end of the insertion rod 51 will abut against the arc-shaped outer edge of the turntable 6 and move horizontally, so that the insertion rod 51 retracts into the second through hole 20. At this time, the movable pressure rod 3 will swing around the middle hinge under the elastic force of the second spring 31, and the pressing part 30 will swing away from the connection plate 11 to release the pressing and fixing of the connection plate 11, and the connection plate 11 and the sound transmission pipe 1 can be easily removed. When it is necessary to overhaul the sound wave generator inside the housing 2 from below, rotate the adjusting part 611, and under the elastic force of the first spring 53, the inner end of the insertion rod 51 closely adheres to the arc-shaped outer edge of the turntable 6 and retracts, so that the outer end of the insertion rod 51 retracts into the first through hole 40 of the cylinder body 42 through the second through hole 20, so that the insertion rod 51 is separated from the connection with the housing 2. At this time, the base 4 can be pulled out from the bottom of the housing 2 to complete the disassembly of the base 4.

[0030] When the sound transmission pipe 1 and the base 4 are installed, first align the positioning block 43 with the positioning groove 22, insert the base 4 below the housing 2, then place the connection plate 11 on the upper part of the housing 2, and by reversely screwing the adjusting part 611, drive the turntable 6 to rotate, so that the insertion rod 51 extends out through the second through hole 20 and abuts against the lower end of the movable pressure rod 3, making the movable pressure rod 3 rotate, and pressing the pressing part 30 against the connection plate 11 for fixing, and the reset installation after maintenance can be easily completed, which is more labor-saving and efficient.
