[0025] Specifically, the fixed block 21 can limit the top end of the shock absorber 23 to be fixedly connected with the outer facade of the heater 1, and the shock absorber 23 is installed outside the fixed block 21 at the upper and lower ends of the heater 1 through the adapter block 22. The upper and lower shock absorbers 23 are mirror-symmetric, the included angle between the shock absorbers 23 is ninety degrees, the other end of the shock absorber 23 is connected with the connecting block 25 through the adapter block 22 and the sliding block 24, when the connecting block 25 is subjected to external force, it will move towards the axis of the heater 1 and make the telescopic rod 26 contract, the position of the connecting block 25 is limited through the telescopic rod 26, so as to press the shock absorber 23 through the sliding block 24, change the inclination angle of the shock absorber 23, and absorb part of the external force through the contraction of the shock absorber 23, so as to protect the heater 1 during installation. At the same time, the fixed block 21 is distributed in the "cross" shape at the upper and lower ends of the heater 1, which can provide anti-collision protection for the heater 1 in four directions, and reduce the influence of vibration generated during equipment operation on the heater 1 after installation.

The contents not described in detail in the specification all belong to the existing technology known to those skilled in the art.

[0028] In operation, the mounting plate 36 is first fixed to the mounting surface by bolts. Since the shock absorbers 23 are mounted on the outer sides of the fixed blocks 21 at the upper and lower ends of the heater 1 via the adapter blocks 22, the shock absorbers 23 on the upper and lower sides are mirror-symmetric. The other ends of the shock absorbers 23 are connected to the connecting block 25 via the adapter blocks 22 and the sliding blocks 24. The distance between the shock absorbers 23 and the heater 1 is limited by the telescopic rods 26. In the initial state, the telescopic rods 26 are in the elongated limit, the included angle between the shock absorbers 23 is ninety degrees, and the sliding blocks 24 on the upper and lower sides of the connecting block 25 are respectively located at the quarter positions on the upper and lower sides of the connecting block 25. When the connecting block 25 is subjected to external force, it will move towards the axis of the heater 1 and cause the telescopic rods 26 to contract. The position of the connecting block 25 is limited by the telescopic rods 26, so that the connecting block 25 presses the shock absorbers 23 via the sliding blocks 24, changes the inclination angle of the shock absorbers 23, and absorbs part of the external force via the contraction of the shock absorbers 23, thereby protecting the heater 1 during installation. Meanwhile, the fixed blocks 21 are arranged in a cross shape at the upper and lower ends of the heater 1, which can provide anti-collision protection for the heater 1 in four directions, reduce the influence of vibrations generated during equipment operation on the heater 1 after installation is completed, and press the movable tube 34 via the transmission plate 39. At this time, the balls 32 can move to the outside of the hole structure of the limiting tube 31. When the cylindrical structure of the connecting block 25 is inserted into the inside of the limiting tube 31, the chamfer at the bottom end of the cylindrical structure of the connecting block 25 will push the balls 32 outward to facilitate the insertion of the limiting tube 31. Meanwhile, the connecting block 25 will drive the reset rod 37 to press the reset spring 38 downward. Then, the transmission plate 39 is loosened, the limiting spring 33 drives the movable tube 34 to move upward, and the movable tube 34 moves upward, which drives the balls 32 to move to the inside end of the hole structure of the limiting tube 31 and embeds part of the balls 32 in the groove on the outside of the cylindrical structure of the connecting block 25, thereby limiting the position between the connecting block 25 and the limiting tube 31. During disassembly, the transmission plate 39 is pressed downward, the reset spring 38 drives the reset rod 37 to move the connecting block 25 upward, the annular recess of the connecting block 25 is disengaged from the balls 32, and the heater 1 with the protection mechanism 2 is directly lifted to complete the disassembly. This method can facilitate the disassembly and assembly of the heater 1, thereby facilitating the maintenance of the heater 1.
