[0026] As a technical optimization scheme of the present utility model, by setting the limit buffer assembly 4, the limit ring 41 can support and limit the bottom of the regenerative condenser body 1 during use. At the same time, the rubber plate 44 can elastically buffer the bottom of the regenerative condenser body 1 to avoid hard collisions between the regenerative condenser body 1 and the inside of the limit ring 41. At the same time, the limit groove can movably limit the surface of the limit plate 43, so that the limit plate 43 can elastically limit the outside of the regenerative condenser body 1 through the elastic plate 45, enhancing the limit stability of the regenerative condenser body 1.

[0027] Reference Figure 3 , the transmission fixing assembly 5 includes a motor 51. The output end of the motor 51 is fixedly connected to a speed reducer 52.

However, since the regenerative condenser is fastened by the mounting frame and bolts during installation, it is rather inconvenient to disassemble, assemble, inspect, and maintain the regenerative condenser, reducing the usage effect of the regenerative condenser.
