[0036] When in use, by setting a box body 2, the box body 2 is a square box with a square bottom surface. During installation, different numbers of boxes 2 can be selected according to the situation of the roof. The arrangement method is flexible. By setting multiple boxes 2 and installing them on the base plate 1 by splicing, and the base plate 1 is placed on the roof, the size of the base plate 1 needs to be set according to the construction area of ​​the roof to ensure that the boxes 2 can be evenly placed on the roof.

The bottom of the back plate 38 is rotatably connected to the connecting rod 41. The two ends of the connecting rod 41 are fixedly connected with a fixing 39. The surface of the fixing 39 is provided with a guide hole 40. The fixing 39 is arranged on the guide rod 34. The inner wall of the guide hole 40 and the outer wall of the guide rod 34 are slidably connected. A rubber column 42 is fixed to the bottom of the fixing 39. The rubber column 42 can abut against the bottom wall of the cavity 33. The inner wall surfaces of the four sides of the box body 2 are provided with a first through hole 43 and a second through hole 5 0, the first through hole 43 is located outside the second through hole 50, the cross-sectional diameter of the hole groove of the first through hole 43 is larger than the cross-sectional diameter of the hole groove of the second through hole 50, and a limiting assembly 100 is arranged in the first through hole 43 and the second through hole 50, and the limiting assembly 100 includes a limiting rod 44, an elastic strip 45, a transmission plate 46 and a pull plate 47, and the limiting rod 44 can be inserted into the limiting hole 36, and the limiting rod 44 is located in the second through hole 50, and the outer wall of the limiting rod 44 is evenly provided with elastic strips 45, One side of the elastic strip 45 is fixedly connected to the outer wall of the limit rod 44, and the other side of the elastic strip 45 is fixedly connected to the inner wall of the second through hole 50.

At the same time, the elastic strip 45 is stretched by hand, and the elastic strip 45 will store elastic potential energy. When the limit hole 36 and the limit rod 44 correspond, the force on the pulling plate 47 is released. At this time, under the elastic action of the elastic strip 45, the limit rod 44 will automatically insert into the limit hole 36, thereby realizing the limitation of the hanging plate 31. Subsequently, the sealing plate 4 needs to be installed with bolts.

This avoids the following problems: In the prior art, traditional green roofs are usually covered on a large area of ​​the roof, which is inconvenient to install. Although traditional green roofs have good thermal insulation performance, the arrangement of their vegetation is not flexible enough and the load is large. The entire roof needs to be surface treated, which is especially difficult for greening the roofs of old houses. At the same time, the drainage performance of traditional green roofs is not ideal.
