[0002] In arid areas such as deserts, salt deserts and Gobi, ecological restoration usually relies on traditional grass grid technology, which is achieved by fixing sand and planting plants. But this method requires a lot of manpower. In these arid and cold environments, the survival rate of artificially planted vegetation is usually not high. Due to the lack of suitable crops such as rice and the shortage of straw raw materials, it mainly relies on external transportation, resulting in high labor and raw material costs. Therefore, in addition to using grass grids, people have also tried methods such as stone grids, soil grids and plastic grids to fix sand and suppress dust, but these traditional technologies also have problems such as high labor demand, low vegetation survival rate, and high cost of continuous irrigation.

[0028] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention:

[0029] like Figure 1-9As shown, an assembled sand-fixing and dust-suppressing device comprises a conical pile 1, a lower substrate 3 with a convex snap button, an upper substrate 4 with a concave snap button, and a mist-catching net 5. The conical pile 1 is inserted into the sand surface near the surface to fix the lower substrate 3. The upper substrate 4 is consistent in shape with the lower substrate 3 and is connected to the mist-catching net 5 through the concave snap button. The mist-catching net 5 is composed of two shell-shaped double-layer mist-catching plates, which are fixedly connected by the connecting ring 6 at the top. The lower substrate 3 is long and connected to the reserved hole of the conical pile 1 through the convex snap button. The upper substrate 4 is connected to the lower substrate 3 through the concave and convex buckles to enhance the stability of the device. The total length of the mist-catching net 5 is 75 cm, of which the upper part is 50 cm long and 30 cm wide; the lower bracket is 25 cm long and 4 cm wide. The fog catching net 5 and the water collecting unit are fixed to the lower substrate 3 through the concave snaps of the upper substrate 4, and then inserted into the soil layer through the conical piles 1 to ensure the stability of the fog catching unit in strong wind weather. The fog catching net 5 is installed on the upper substrate 4 through the bottom bolt hole 10. The fog catching net 5 and the water collecting unit are arranged in parallel or in a grid at a spacing of 1.0m to complete the fixed implementation of the sand fixation and dust suppression unit. Under the action of gravity, the upper fog catching water flows into the surface soil layer through the water pipe, increasing the humidity of the surface soil layer, achieving the effect of sand fixation, humidification, wind prevention and dust suppression. Its working principle is to imitate the biological surface structure through the water collecting unit of the fog catching net, capture the fog in the air, condense the fog into water droplets, and then collect it as liquid water by the water collecting unit. Under the action of gravity, these liquid water passes through the water-conducting humidification unit. Part of it is used to humidify the surface soil layer in the device installation area, promoting vegetation growth to achieve the purpose of soil and sand fixation; the other part is used in the humidification unit to increase the air humidity, and cooperate with the device to reduce flying sand and dust, thereby achieving bionic fog capture, sand fixation, humidification and dust suppression effects.

[0030] The conical pile 1 is made of polymer composite materials. By adding specific additives and adopting special processing technology, a bionic fog-catching material with micro-convex particle structure and spiral feather structure similar to the surface of desert insects is prepared. The side wall is provided with upward anti-pullout barbs 2 to ensure that the device is not easy to slip after being inserted into the ground.

[0031] The horizontal mesh line 7 has an angle of 30° with the horizontal, and the vertical mesh line 8 has a water collection trough 801, and the width and depth of the water collection trough 801 are both 0.2 cm. The horizontal mesh line 7 and the vertical mesh line 8 are connected through the mesh hole 9 on the fog catching net 5, and the spacing between the horizontal mesh line 7 and the vertical mesh line 8 is 5 cm. The spiral feather piece 11 is wrapped around the vertical mesh line 8, and the diameter of the vertical mesh line 8 is 0.6 cm. The fog catching net 5 is made into a double-shell four-layer feather-shaped fog catching and water collection net, and the fog catching plate in the fog catching net 5 can be designed into a rectangular, triangular, etc. shape. The spiral feather piece 11 is fixed on the vertical mesh line 8 of the double-shell frame, with a width of 2 cm, and has a horizontal mesh line 7 with a protrusion 701 particle on the surface (with an angle of 30° with the horizontal) to form a double-shell four-layer fog catching net 5, the protrusion 701 particle height is 0.2 cm, and the diameter of the horizontal mesh line 7 is 0.3 cm. According to the local wind direction, wind speed and fog flow law, the double-shell four-layer fog-catching net 5 is fixed on the lower substrate 3 at a certain angle and spacing to form a multi-layer fog-catching array. In areas with relatively stable wind direction, the fog-catching water collection net / plate can be arranged perpendicular to the wind direction, and the spacing between adjacent fog-catching nets 5 is 0.5-1.0m (or 1.0m in a square grid). The inclination angle of the double-shell four-layer fog-catching net 5 is adjusted according to the terrain to intercept fog to the greatest extent and increase the area and efficiency of fog-catching. The water collection trough 801 reserved on the vertical mesh line 8 in the fog-catching net 5, when the spiral feather pieces 11 and the horizontal protrusions 701 on the vertical mesh line capture the condensed water droplets, under the action of gravity, gather in this water collection trough 801 to form a water collection unit. The water collection unit can be made of corrosion-resistant material, and its shape and size must match the fog-catching net 5 to ensure that all water droplets can be effectively collected. So that the water droplets can flow smoothly to the lower conduit of the double-shell four-layer feather-shaped fog-catching net 5.

[0032] Various sensors (wind speed sensor, wind direction sensor, humidity sensor, temperature sensor, light intensity sensor, etc.) can be added to the device to monitor environmental parameters and the operating status of the device. The data collected by the sensor is collected and processed by the data acquisition module, and then transmitted to the control center through wired or wireless communication to accurately obtain environmental information. The control center uses corresponding control strategies and algorithms to automatically control the operation of the device based on the received data. At the same time, the control center also has fault diagnosis and alarm functions. When the sensor detects abnormal data or the device fails, it will send an alarm signal in time to remind the staff to handle it.

[0033] Under the test environment, the feather-shaped double-layer fog-catching net on each side can capture fog and form 8g of liquid water in 24 hours, that is, each square fog-catching area (four sides) can collect no less than 24g of fog water in 24 hours. Through the setting and operation of the device, in a hydrological year, the loss of desert sandy soil within a radius of 10m is significantly reduced, the loss of sand and soil is reduced by more than 60%, and the vegetation coverage rate is increased by more than 20%. Under the condition of a wind speed of level 8, the dust concentration in the air within a radius of 10m around the device is reduced by more than 80%, so that the air quality in the area is significantly improved. And under the action of a wind of level 8, the structural displacement of the device does not exceed 10cm, and the connections between the components should remain intact; under the action of a magnitude 8 earthquake on the Richter scale, the device does not collapse and can continue to work normally. Under the conditions of normal use and maintenance, the service life of the main components of the device is more than 50 years. In an environment with a temperature range of -30℃ to 50℃, the performance indicators of the device remain within 95% of the design requirements, and the fog capture efficiency remains above 80% of the design value. It has good applicability in desert environments in different seasons and regions.
