Description

Self-adaptive wind-proof sand-resistant device

Technical Field

The utility model relates to a prevent wind sand-blocking device along the line of engineering such as railway, highway, in particular to self-adaptation prevents wind sand-blocking device.

Background

The method is characterized in that sand moves frequently, gravels on the exposed ground are easily blown by strong wind, sand storm disasters are frequent, the gravels are piled and buried after the gravels meet structures such as railways, roads and the like along the line, life and travel of people are slightly influenced, life and property safety of human beings are threatened, and the method becomes a difficult problem to be solved urgently.

At present, the measures for treating the wind and sand disasters are mainly divided into two categories: engineering sand control and plant sand control. The engineering sand fixation mainly adopts reeds and straws to manufacture grid sand barriers and vertical sand barriers, although a certain sand fixation effect is achieved, the economic cost is high, the phenomena of damage, wind break, sand burying and the like can occur after the engineering sand fixation is used for two years, and the new arrangement is needed; the sand barrier that also has the plastic mesh grid to make, in order to satisfy the ventilation rate, the net muscle diameter of mesh grid makes very thin, leads to in the natural environment after the weather of blowing, its durability, practicality become extremely poor, meet strong wind weather after the mesh grid is ageing, can be blown off and fly upward, and later stage clearance is extremely wasted time and energy, not only causes the engineering inefficacy, has also caused serious destruction to the environment. The plant sand control mainly is afforestation, and the sand control forest belt is established, and the nursery stock can survive only by ensuring sufficient water source under proper natural environment conditions, but the nursery stock has a longer growth period and can not solve the problem of sand damage in a short time.

Disclosure of Invention

An object of the utility model is to provide a self-adaptation is prevent wind and is hindered husky device can give the fine bending resistance of structure, tensile strength, can effectively reduce the wind speed, alleviate sand damage, and the performance is good, take effect soon, construction convenient and fast.

The utility model aims at realizing the self-adaptive wind-proof sand-resistant device, which comprises two columns, a connecting shaft and a rotating plate, wherein the columns are reinforced concrete columns or section steel columns, round holes for placing the connecting shaft are reserved in the direction vertical to the columns, the rotating plate is a concrete plate or a polymer plate, a through hole is arranged at the top of the rotating plate, and the connecting shaft passes through the through hole and is respectively inserted into the round holes of the two columns; the rotating plate is hung by a connecting shaft and swings with wind.

The stand adopts reinforced concrete or shaped steel, the perpendicular stand direction leaves the round hole of placing the connecting axle, the connecting axle adopts steel or polymer, the rotor plate adopts concrete or polymer, set up circular reservation trepanning with the rotor plate top, make it cover on the connecting axle, be fixed in the stand with the connecting axle, when the rivers blow to the rotor plate on, the rotating plate relies on the connecting axle automatic production to rotate and the vertical direction produces certain angle under the effect of wind force, keep receiving the balance between wind-force and the self gravity, thereby change whole prevent wind, the wind permeability of sand-blocking system, effectively improve the anti-wind ability of wind-proof system through self-adaptation process, it is difficult to be buried to reach the sand barrier, increase the purpose of service life. The wind and sand flow can be decelerated and accumulated after meeting the rotating plate, and the effects of reducing wind speed and lightening sand damage are achieved. According to the danger degree of local wind and sand disasters, the device can be selected to be arranged on two sides of a railway or a highway in a single row or multiple rows, so that the requirements of wind prevention and sand fixation of the railway, the highway and other projects are met.

Detailed Description

A self-adaptive wind-proof sand-blocking device is shown in figures 1, 2, 3 and 4 and comprises two upright posts 1, a connecting shaft 2 and a rotating plate 3, wherein the upright posts 1 are reinforced concrete columns or section steel columns, round holes for placing the connecting shaft are reserved in the direction vertical to the upright posts, the rotating plate is a concrete plate or a polymer plate, through holes are formed in the top of the rotating plate, and the two connecting shafts respectively penetrate through the through holes of the rotating plate and are respectively inserted into the round holes of the two upright posts 1; the rotary plate 3 is hung by the connecting shaft 2 and swings with wind. The cross-sectional dimension of the upright posts 1 is generally 150mm multiplied by 150mm-300mm multiplied by 300mm, the height of the upright posts 1 is generally 1500-3000mm, the two upright posts 1 are respectively provided with a circular hole for erecting a connecting shaft, the diameter of the circular hole is 30-80mm, the length of the connecting shaft 2 is generally 2000-4000mm, the diameter is 20-60mm, the connecting shaft is made of steel or polymer, the connecting shaft sleeve is matched with the length of the connecting shaft, a plurality of or single rotating plates 3 can rotate at a certain angle depending on the self weight, the rotating plates 3 are square or rectangular, the size of the rotating plates is 50cm multiplied by 50cm or 50cm multiplied by 200 cm-400cm, the thickness is 10-50mm, and the rotating plates are made of concrete or polymer. When wind current meets the rotating plate, the rotating plate can rotate at a certain angle (less than or equal to 60 degrees), a gap can be formed between the upper row of rotating plate and the lower row of rotating plate, a certain wind penetration rate is formed, at the moment, the wind direction and the wind speed of the wind sand current can be changed, a weak wind area is formed behind the rotating plate, the wind sand current can be accumulated in front of and behind the sand blocking device, and therefore the wind-proof sand blocking system is formed, and accumulation of sand on structures such as railways and highways can be reduced.
