The invention relates to the field of plant shaping and cultivating, in particular to a manmade plant manufacturing method and a manmade plant. The manmade plant manufacturing method includes the following steps that a solid fixing frame is manufactured, part of the solid fixing frame is pre-buried underground, and multiple ring-shaped temporary growing belts are arranged on the outer circumferential face of the exposed part of the solid fixing frame from bottom to top. A sapling is shaped as preset in a grafting mode and becomes a grafted sapling. Multiple grafted saplings are implanted into each ring-shaped temporary growing belt and fixed in the solid fixing frame. The grafted saplings of adjacent ring-shaped temporary growing belts undergo grafting and become re-grafted saplings. After a preset time period and the re-grafted samplings are mature, the saplings are manufactured into manmade plants. The height of the solid fixing frame can be selected according to the height of a high-rise and the manmade plant can solve environmental problems by purifying the air outside the high-rise.

A gas detection purification device is disclosed and includes a main body, a purification unit, a gas guider, a gas detection module and a controlling-driving module. The main body includes an inlet, an outlet, an external socket and a gas-flow channel disposed between the inlet and the outlet. The purification unit is disposed in the gas-flow channel for filtering gas introduced through the gas-flow channel. The gas guider is disposed in the gas channel and located at a side of the purification unit. The gas is inhaled through the inlet, flows through the purification unit and is discharged out through the outlet. The gas detection module is plugged into or detached from the external socket. The controlling driving module is disposed within the main body and electrically connected to the gas guider to control the operation of the gas guider in an enabled state and a disabled state.

The invention provides a wind-proof and dust suppressing net for traffic engineering construction. The problem that the existing wind-proof and dust suppressing net is troublesome to assemble and disassemble is effectively solved. The wind-proof and dust suppressing net for traffic engineering construction comprises a plurality of bottom shells; a mounting groove is formed in each bottom shell; the mounting grooves comprise T-shaped grooves; vertical stopping blocks are arranged on the two sides in the T-shaped grooves; first triangular clamping blocks are connected to the bottoms of the two ends of the T-shaped grooves; first anti-rotation grooves are formed in the tops of the two ends of the T-shaped grooves; second anti-rotation grooves are formed in the two side walls of the T-shaped grooves; triangular third anti-rotation grooves are formed in the internal sides of the vertical stopping blocks; vertical wind-proof and dust suppressing nets are placed in the mounting grooves in a sliding manner; the lower ends of the wind-proof and dust suppressing nets are placed in the mounting grooves; the structures of the wind-proof and dust suppressing nets are matched with those of the mounting grooves; inserting blocks and inserting grooves are correspondingly arranged on the two end walls of the wind-proof and dust suppressing nets; a pair of rotating blocks which correspondingly rotate in the inserting groove is arranged in each inserting groove; and the inserting blocks of each two adjacent wind-proof and dust suppressing nets are inserted in the rotating blocks in a movablemanner. The wind-proof and dust suppressing net for traffic engineering construction has the advantages that the structure is skillful, the mounting is simple, the movement is convenient, and the wind-proof and dust suppressing net for traffic engineering construction is uneasy to fall down and is stable and firm with rotating.

A high power outdoor cabinet cooling air duct structure comprises air inlet structure components at the two sides of the top of a cabinet and cabinet air outlet structures at the two sides of the bottom of the cabinet. The cabinet is separated four independent cavity chambers by air duct dummy plates according to different heat resistance level of the components in the cabinet, and the four independent cavity chambers are a first cavity chamber, a second cavity chamber, a third cavity chamber and a fourth cavity chamber. The high power outdoor cabinet cooling air duct structure further comprises an axial flow fan, a backward centrifugal fan and an electric reactor, wherein the axial flow fan is arranged in the first cavity chamber and is located at the bottom of the air duct dummy plate between the first cavity chamber and the second cavity chamber; the backward centrifugal fan is arranged in the third cavity chamber and is linked with a GBT module radiator structure component, the electric reactor is arranged below the backward centrifugal fan; the air inlet structure component at the one side of the top of the cabinet is communicated with the first cavity chamber, and the air inlet structure component at the other side is communicated with the third cavity chamber. The air duct has the advantages of being simple and compact in structure, high in protective capability, high in cooling efficiency and low in cost.
