[0035] The heat preservation cover 6 is installed at the other end of the Z-shaped plate 4, and the Z-shaped plate 4 is driven to rotate around the rotating shaft 5 by the power device to control the heat preservation cover 6 to be opened or closed.

[0036] The power device is a hydraulic cylinder 1 , the bottom of the cylinder body of the hydraulic cylinder 1 is hinged to the base; the top of the hydraulic rod 2 of the hydraulic cylinder 1 is hinged to one end of the Z-shaped plate 4 .

[0037] The heat preservation cover 6 can be quickly opened or closed through the power device (i.e., the hydraulic cylinder 1), the support seat, the rotating shaft 5 and the Z-shaped plate 4, and since the Z-shaped plate 4 only rotates on a plane around the rotating shaft 5, that is, the heat preservation cover 6 can only move upward or downward and will not move left and right, which effectively ensures the accuracy of the position of the heat preservation cover 6 when closed and greatly improves the opening or closing efficiency of the heat preservation cover 6.

[0038] The support column 3 has a positioning pin 7 , and the positioning pin 7 is arranged above the rotating shaft 5 ; the Z-shaped plate 4 has two positioning holes corresponding to the positioning pin 7 .

When the heat preservation cover 6 is closed, the hydraulic cylinder 1 is started to be extended slowly so that there is a small gap between the positioning pins 7, the positioning pins 7 are pulled out, the hydraulic cylinder 1 continues to be extended, and the heat preservation cover 6 is lowered by the Z-shaped plate 4 and the rotating shaft 5 until the heat preservation cover 6 is closed, the positioning pins 7 are reinserted into the corresponding positioning holes, the hydraulic valve is closed, and the action is completed.

[0040] The insulation cover 6 includes a U-shaped shell, and an insulation layer 64 arranged on the inner wall of the U-shaped shell.
