Abstract
The invention discloses a flow guide type sand-proof net which mainly solves the problem of an existing desert managing tool that a flow guide effect is poor and then solves the problems that the desert managing tool cannot be repeatedly used and has a short service life. The flow guide type sand-proof net is formed by connecting sand-proof plates through connecting columns which are provided with sand-proof plate inserting grooves and bolt holes; the end parts of the sand-proof plates are provided with sand-proof plate holes and the end parts of the sand-proof plates are inserted into the sand-proof plate inserting grooves; and stopping bolts are clamped into the bolt holes and the sand-proof plate holes. The sand-proof principle of the flow guide type sand-proof net as follows: by taking a T-shaped flow guide sand-proof plate as an example, an outer circular arc of the top face of the T-shaped flow guide sand-proof plate takes effect with inner circular arcs at the lower two sides; when sand wind directly invades, a vortex which whirls downwards and backwards is formed in front of an umbrella-shaped sand-proof plate, so as to be good for leaking sand grains into a grid along with the whirled vortex; and therefore, the sand-proof and sand fixing aims are realized. The flow guide type sand-proof net disclosed by the invention has the advantages of good low guide effect, good sand-proof effect, repeated utilization and long service life.
Description
Technical field
the present invention relates to control of desert field, particularly a kind of flow-guide type sand protection net.
Background technology
the mode of existing Desert Control is mainly the variety of ways such as straw checkerboard barrier, sand proof net, desert surface sprinkling chemical sand-fixing materials.Taking straw checkerboard barrier as example, its shortcoming is not reproducible use, and laying is wasted time and energy, and application life is very short, can discard by nature.Use chemical sand-fixing materials to be also unfavorable for environmental protection.
Summary of the invention
the object of this invention is to provide a kind of flow-guide type sand protection net, mainly solve the effective problem of water conservancy diversion that existing Desert Control apparatus exists, secondly solve the short problem of not reproducible use, life-span that Desert Control apparatus exists.
the present invention is by the following technical solutions: it is formed by connecting sand prevention plate by joint pin, described joint pin is provided with sand prevention plate slot and pin hole, the end of sand prevention plate is provided with sand prevention plate hole, and insert in sand prevention plate slot the end of sand prevention plate, and retaining latch snaps in pin hole and sand prevention plate hole.
as a further improvement on the present invention, the end of described sand prevention plate be shaped as semicircle.
further improve as of the present invention, described sand prevention plate slot is 4, is cross setting on horizontal plane.Described sand prevention plate slot also can be 3, in first-class point of setting of horizontal plane.
further improve as of the present invention, described joint pin is cylindrical, square column type or triangle cylindricality.
further improve as of the present invention, described joint pin top is provided with drop handle.
further improve as of the present invention, described sand prevention plate has three kinds of shapes, and one is that longitudinal cross-section is T shape flow-guiding type sand prevention plate, and T section end face is cylindrical arc, and T section end face following side is interior circular arc.Another kind of sand prevention plate longitudinal cross-section is T shape sand prevention plate.Also having a kind of sand prevention plate longitudinal cross-section is bar shaped sand prevention plate.
the material of the various joint pins of the present invention, sand prevention plate is to add the existing technique of sand material to make taking netted core as skeleton, to increase its intensity.The production of sand prevention plate and joint pin can factory form produce, also can, at the edge of the desert in the mode of small-sized production, gather materials on the spot, utilize endless husky resource.
the sand prevention principle of flow-guide type sand protection net of the present invention is: taking T shape flow-guiding type sand prevention plate as example, utilize the interior circular arc effect of both sides under the external arc of T shape flow-guiding type sand prevention plate top surface and end face, at the eddy current that forms downwards in the time that dust storm is directly attacked before umbrella shape sand prevention plate and circle round backward, be beneficial to the grains of sand along with the eddy current of convolution is let out in grid, to reach the object of preventing and fixing sand.
sand proof net of the present invention after the use of certain hour, drift sand can constantly leak in grid to form and pile up, after drift sand accumulation can not be played the effect of preventing and fixing sand to a certain extent, people can mention the circular drop handle of joint pin top gently by the mode with artificial, the plate of sand prevention simultaneously also can be mentioned along with the lifting of joint pin, so just can form again a new sand proof net lattice group body, thereby play reusable effect, to reduce, the secondary of various materials drops into and a large amount of artificial input.Various joint pin upper rounded drop handles can also play the effect of the waterline that connects energy-conservation drip irrigation simultaneously, to realize the raw husky plant of plantation and industrial crops.
flow-guide type sand protection net water conservancy diversion of the present invention is effective, and dustproof effect is good, can reuse, and the life-span is long.
