The specific embodiment

The present invention is further described below in conjunction with drawings and Examples:

In embodiment shown in Figure 1, this cement protecting box comprises main box 1, and described main box 1 has lagging casing; The humidity sensor that is provided with damping device in the inner chamber of described main box 1 and is coupled with damping device (the non-improvement part of this part, not shown); Described main box 1 outside also is provided with an attemperater 2, be provided with electrothermal tube 21 in it, the conduit 3 of water body in the joining water box is drawn in described attemperater 2 bottoms, described conduit 3 wriggles and extends each surface (in schematic diagram shown in Figure 1, only illustrating the catheter segment in main box 1 inner chamber) of described main box 1 inner chamber; In the present embodiment, described conduit 3 is the blister copper pipe, and diameter is 8mm-16mm, between described attemperater 2 and main box 1, form the single channel extended structure, the top that is described conduit 3 is communicated with described attemperater 2, and end is in described main box 1 inner chamber, is a blind end; Be serially connected with the automatically controlled on-off valve 4 of control conduit 3 interior hot water flows in the described conduit 3, this automatically controlled on-off valve 4 is coupled with the temperature sensor 5 of being located in described main box 1 inner chamber, when the temperature that senses main box 1 inner chamber when temperature sensor 5 does not reach preset temperature, automatically controlled on-off valve 4 is opened, otherwise closed automatically controlled on-off valve 4; When automatically controlled on-off valve 4 is opened because conduit 3 is thicker, the water body in the attemperater 2 will with main box 1 in conduit 3 in water body convection current occurs fast, thereby heat is evenly diffused in the main box 1.
