Description
Technical field
The utility model relates to for protecting dust storm to the impact of the facility such as railway or the device of preventing and fixing sand that destroys, and especially one prevents railway sand window windbreak, belongs to the husky technical measures of resistance in sand-prevention engineering field.
Background technology
China has vast territory, and weather is complicated and changeable, and many railways are in dust storm area or even air port, and these regional wind-force are powerful, and strong wind is frequent.When wind-force is powerful, strong wind sweeps along grit to blow to circuit, causes the problems such as the increase of window on train glass breakage, plate knot of ballast bed, rail abrasion, the minimizing of travelling facility life-span.Since operation opened by railway, cause a lot of accident by strong wind, have a strong impact on transportation safety and benefit.For this reason, people take various measure and ensure railway operation safety, main based on sand control with biological measures measure and the measure of engineering sand-proof at present.Sand control with biological measures is forever reliable, but is subject to hydrogeological conditions and natural environment influence comparatively large, there is certain limitation.Engineering sand-proof measure utilizing works building intervene stream flow field, and reach the object reducing wind speed, reduce to take husky amount, it is little by region restriction, is widely used, wherein, and the windbreak of the most frequently used is exactly various material and form.Windbreak in actual use, owing to reducing the wind speed near windbreak, making to carry gravel part in wind is deposited on before and after windbreak, in the past for a long time, windbreak part (even whole) can be caused to bury, lose its effect, after wall, sand can be accelerated rail abrasion especially, reduce the travelling facility life-span, even bury rail, train cannot be run, its harmful effect caused railway is very serious.Therefore in the use procedure of windbreak, need regularly to carry out artificial clear sand, its process wastes time and energy, and poor effect.
Summary of the invention
The purpose of this utility model be to provide a kind of structure simple, sand after wall can be greatly reduced, effectively alleviate rail abrasion, do not need manually to carry out husky, economical and practical clearly preventing railway sand window windbreak to rail.
The utility model discloses one and prevent railway sand window windbreak, it is characterized in that being arranged side by side by multiple module 6 of keeping out the wind forming, the structure of described module 6 of keeping out the wind mainly comprises the column 1, baffle plate 2, the aerofoil 4 that are embedded in sand ground, the both sides of baffle plate 2 are located at by described column 1, aerofoil 4 is located at the below of baffle plate 2, and hinged by damp hinge 3, column 1 described in every root is provided with block 5 in the side near aerofoil 4.
Also do not have lower baffle plate 8 below described aerofoil 4, lower baffle plate 8 is fixedly connected with column 1.
Magnetic rubber pad 7 is provided with on described block 5 and near the one side of aerofoil 4.
The effect of damp hinge is that when preventing wind speed instability, aerofoil swings back and forth.Damping force and the velocity of rotation of described damp hinge are proportionate.
Described magnetic rubber pad is preferably strong magnetic rubber pad, and its effect has: 1. the impact 2. when cushioning fender falls, when wind-force is faint, prevents aerofoil from being blown afloat.
The material require of described aerofoil is more thick and heavy, prevents weight too light, is blown afloat under gentle breeze.When wind is enough large, aerofoil can be blown afloat, after aerofoil is blown afloat, wind just can pass through aerofoil hole and blows to rail, and then blow farther by the sand on rail, thus drift sand is prevented to pile up on rail, when wind is not very large, aerofoil is closed condition, forms windbreak, by drift sand gear outside rail.Utilize high wind directly can blow away drift sand on rail like this, do not need artificial clear husky.Another effect can also blow away the sand before and after windbreak, effectively reduces sand.
Compared with prior art, the beneficial effects of the utility model are: provided by the utility modelly prevent railway sand window windbreak, by multiple column keeping out the wind module 6 is fixed on sand ground, be arranged side by side at the direction of the wind comes from of railway, form the windbreak of certain length, the invasion and attack of effective stop drift sand, in addition the wind comes from enough large in, aerofoil is opened, high wind is made directly to blow farther by drift sand, be unlikely to sand on rail, compared with prior art, the utility model has the advantages that structure is simple, save artificial clear husky labour cost, sand after wall can be greatly reduced, effectively alleviate rail abrasion, a kind ofly economical and practical prevent railway sand window windbreak.

Detailed description of the invention
Embodiment 1:
With reference to Fig. 1-Fig. 5, one prevents railway sand window windbreak, it is characterized in that being arranged side by side by multiple module 6 of keeping out the wind forming, the structure of described module 6 of keeping out the wind mainly comprises the column 1, baffle plate 2, the aerofoil 4 that are embedded in sand ground, the both sides of baffle plate 2 are located at by described column 1, aerofoil 4 is located at the below of baffle plate 2, and hinged by damp hinge 3, and column 1 described in every root is provided with block 5 in the side near aerofoil 4.
The effect of damp hinge is that when preventing wind speed instability, aerofoil swings back and forth.Damping force and the velocity of rotation of described damp hinge are proportionate.
Described magnetic rubber pad is preferably strong magnetic rubber pad, and its effect has: 1. the impact 2. when cushioning fender falls, when wind-force is faint, prevents aerofoil from being blown afloat.
The material require of described aerofoil is more thick and heavy, prevents weight too light, is blown afloat under gentle breeze.When wind is enough large, aerofoil can be blown afloat, after aerofoil is blown afloat, the hole that wind just can pass through aerofoil blows to rail, and then blows farther together by the sand on rail, thus prevents drift sand to pile up on rail, when wind is not very large, aerofoil is closed condition, forms windbreak, by drift sand gear outside rail.Utilize high wind directly can blow away drift sand on rail like this, do not need artificial clear husky.
Its role is to: by multiple column keeping out the wind module 6 is fixed on sand ground, be arranged side by side at the direction of the wind comes from of railway, form the windbreak of certain length, the invasion and attack of effective stop drift sand, in addition the wind comes from enough large in, aerofoil is opened, and makes high wind directly blow farther by drift sand, is unlikely to sand on rail.
Embodiment 2:
Compared with embodiment 1, the difference of the present embodiment is also to be provided with lower baffle plate 8 below described aerofoil 4, is fixedly connected with between lower baffle plate 8 with column 1.
Embodiment 3:
Compared with embodiment 1, the difference of the present embodiment is to be provided with magnetic rubber pad 7 on described block 5 and near the one side of aerofoil 4.
Embodiment 4:
Compared with embodiment 2, the difference of the present embodiment is to be provided with magnetic rubber pad 7 on described block 5 and near the one side of aerofoil 4.
