The invention relates to the field of sand wind prevention and control, and provides a protection device and a protection system suitable for a sand wind area. The protection device comprises a plurality of wind-proof and sand-blocking bodies and a fixed stand column, wherein every two adjacent wind-proof and sand-blocking bodies are in butt joint and are positioned on the same plane, the fixed stand column is provided with a connecting surface, and the connecting surface is tightly attached to the leeward surface of the butt joint position; or the fixed stand column is fixed between the two wind-proof and sand-blocking bodies, the side, positioned on the windward surface, of the fixed stand column is constructed into a blocking plane, and the blocking plane and the windward surfaces of the two adjacent wind-proof and sand-blocking bodies are positioned on the same plane; or the fixed stand column is arranged between the two adjacent wind-proof and sand-blocking bodies, the side, positioned on the windward surface, of the fixed stand column protrudes out of the windward surfaces of the wind-proof and sand-blocking bodies, the protruding surface of the fixed stand column is a fluidsurface, and the included angles of the connecting positions of the side faces, positioned on the windward surfaces, of the adjacent wind-proof and sand-blocking bodies and the fluid surface are larger than 90 degrees. According to the protection device and the protection system, the technical problem that due to the fixed stand column structure in the prior art, the fixed stand column is positioned on one side of the protection area, and a sand accumulation area is prone to being formed is solved.
Description
Technical field [0001] The invention relates to the technical field of sandstorm prevention and control, in particular to a protection device and a protection system suitable for sandstorm areas. Background technique [0002] The most common type of wind and sand control engineering is wind and sand resistance devices, such as wind walls, sand walls, sand barriers on the side of the roadbed, etc. Most of the columns in these wind and sand prevention devices are rectangular and windproof. The sand-resisting devices are basically located in the middle of these rectangular structural columns, that is, the columns are parallel to the two sides of the wind-sand-resisting device and the plane of the wind-sand-resisting device is not on the same plane. [0003] However, there are at least the following problems with the pillars in the wind and sand resistance device in the prior art: [0004] (1) The pillars in the prior art cause the sand accumulation area on the side of the protection ar...
