Description

Technical Field

[0001] The utility model relates to the technical field of wind-blown sand prevention and control, in particular to sand retaining equipment for wind-blown sand prevention and control. Background Art

[0002] Aeolian sand is a layer of sand that is blown and deposited by the wind. It is often found in deserts and Gobi. Its particle size is mainly distributed between 0.074 and 0.250 mm, with a content of more than 90%. Particles larger than 0.25 mm are very rare, only 0.1%. And particles smaller than 0.074 mm are less than 9%. The unevenness coefficient is about 1.35.

[0003] Highway sand damage prevention refers to the technical measures taken to prevent the wind erosion and sand burial of highways in sandy areas. China's sandy areas cover about 700,000 km2, mainly distributed between the north latitude and the east longitude. Wind erosion is the phenomenon of road shoulders and slopes being damaged by wind and sand, such as roadbed reduction, hollowing out and collapse. Sand burial is the phenomenon of roadbed being buried by sand accumulation due to wind and sand flow and sand dune movement. Sand burial is the most harmful, seriously affecting people's travel and increasing the probability of traffic accidents. Solving the problem of sand damage is urgent. Summary of the invention

[0012] The beneficial technical effect of the utility model is as follows: the utility model is installed on both sides of the highway, and the wind speed and wind direction are detected by a wind direction and anemometer. When the wind speed is low, the adjacent baffles fit together on opposite sides, and a group of baffles forms a state of an ordinary protective wall. When the wind speed is high, the baffle adjustment structure is started to adjust the angle of a group of baffles (generally tilted downward by 30°, and the specific angle is adjusted according to the wind speed and the site). Sand hits the baffles and slides down along the inclined surface of the baffles. The wind blows through the gaps between adjacent baffles, which can effectively prevent the sand from being blown onto the highway. At the same time, the gaps between the baffles reduce the pressure caused by the strong wind, thereby increasing the service life of the device. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] Please refer to the attached Figure 1-Figure 6 Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0021] The utility model proposes a sand retaining device for preventing and controlling wind-blown sand. When using the device, a suitable installation method is selected according to the terrain and soil conditions on both sides of the road where the device is installed. The device is installed on both sides of the road through the installation assembly, and the lower swing end of a group of baffles 4 faces the outside of the road (such as Figure 2 As shown, this form is the side facing away from the road), which is used for subsequent sand blocking. The adjacent mounting frames 3 and protective shells 13 are installed together through the connecting components to form a sand blocking wall. The wind direction and wind speed are monitored by the wind direction and wind speed meter 8. When the wind speed is low, the output end of the electric push rod 2 is in a fully extended state. At this time, the adjacent baffles 2 are attached to each other at one end, and a group of baffles 2 form a state of a common protective wall, such as Figure 1 As shown, when the wind direction and anemometer 8 detects that the wind speed is relatively high, the electric push rod 2 is started, and the output end of the electric push rod 2 retracts to drive the slide plate 7 to slide upward, and the slide plate 7 drives the trapezoidal slide bar 10 to slide upward along the trapezoidal slot plate 12, and the slide plate 7 drives a group of slide grooves 9 to slide upward, and a group of slide grooves 9 drives the corresponding slide column 11 to slide along the slide groove 9. At the same time, a group of slide grooves 9 drives the corresponding L-shaped rods 6 to swing upward through the corresponding slide column 11, and a group of L-shaped rods 6 drives the corresponding baffles 4 to swing upward. When a group of baffles 4 swings to a suitable angle (generally tilted downward by 30°, and the specific angle is adjusted according to the wind speed and the site), the electric push rod 2 is closed, as shown in FIG. Figure 2-3 As shown, after the sand hits the inclined baffle 2, it slides down along the inclined surface of the baffle 2, and the wind blows through the gaps between adjacent baffles 4, which can effectively prevent the sand from being blown onto the road. At the same time, the gaps between the baffles 2 reduce the pressure caused by the strong wind, increase the service life of the device, solve the problem of safety hazards caused by a large amount of sand blowing onto the road, and reduce the probability of traffic safety accidents.
