[0052] Specifically, the first sealing strip 105 may be a flexible sealing strip in the prior art.

[0053] like Figure 3 As shown, in order to facilitate driving the first flip bottom plate 103 and the second flip bottom plate 104, this embodiment is modified on the basis of the above embodiment. The difference from the above embodiment is that two pairs of driving hydraulic cylinders 107 are provided on the house body 10, one pair of driving hydraulic cylinders 107 is respectively arranged on both sides of the first expansion window 101, and the other pair of driving hydraulic cylinders 107 is respectively arranged on both sides of the second expansion window 102;

[0055] Among them, a pair of driving hydraulic cylinders 107 located on both sides of the first expansion window 101 can drive the first flip bottom plate 103 to flip to close the first expansion window 101, and at the same time, the closing plates 109 located on both sides of the first flip bottom plate 103 close the installation slots 108 on both sides of the first expansion window 101; the pair of driving hydraulic cylinders 107 located on both sides of the first expansion window 101 can also drive the first flip bottom plate 103 to flip to be in the same straight line with the bottom of the house main body 10; the pair of driving hydraulic cylinders 107 located on both sides of the second expansion window 102 can drive the second flip bottom plate 104 to flip to close the second expansion window 102, and at the same time, the closing plates 109 located on both sides of the second flip bottom plate 104 close the installation slots 108 on both sides of the second expansion window 102; the pair of driving hydraulic cylinders 107 located on both sides of the second expansion window 102 can also drive the second flip bottom plate 104 to flip to be in the same straight line with the bottom of the house main body 10.

[0056] The hydraulic cylinder 107 can be driven by a hydraulic cylinder in the prior art that can realize the function of the present utility model. The hydraulic cylinder 107 can also be driven by a pneumatic cylinder or an electric cylinder in the prior art to replace it.

[0057] When in use, the hydraulic cylinder 107 can be driven to drive the first flip bottom plate 103 and the second flip bottom plate 104 to flip to be on the same straight line with the bottom of the house body 10, and the hydraulic cylinder 107 can also be driven to drive the first flip bottom plate 103 and the second flip bottom plate 104 to flip to a closed state.

[0058] like Figure 1 、 Figures 6 and 7 As shown, in order to facilitate the installation of the house main body 10, this embodiment is modified on the basis of the above embodiment.
