Abstract
The utility model discloses a flow-guide type sand protection net, which mainly solves the problem in the existing desert control tool that the flow guide effect is poor and secondly solves the problems that the existing desert control tool is not reused, the service life of the tool is short. The flow-guide type sand protection net is formed by connecting sand protection plates by connecting pillars, wherein sand protection plate inserting grooves and pin holes are arranged on the connecting pillars; sand protection plate holes are arranged at the end parts of the sand protection plates; the end parts of the sand protection plates are inserted into the sand protection plate inserting grooves; and backstop pins are clamped into the pin holes and the sand protection plate holes. The sand protection principle of the flow-guide type sand protection net is as follows: taking the T-shaped flow-guide type sand protection plates for example, under the action of the outer arc on the top surface of each of the T-shaped flow-guide type sand protection plates and the inner arcs at the two side parts of the top surface of each of the T-shaped flow-guide type sand protection plate, when windblown sand attacks, downward and backward convoluted vortex is form in front of the umbrella-shaped sand protection plates, so that the sand is leaked into grids along with the convoluted vortex, so as to achieve the aims of sand protection and sand stabilization. The flow-guide type sand protection net has good flow guide effect, good sand protection effect and long service life and can be reused.
