[0002] In arid regions such as deserts, salt deserts and Gobi, ecological restoration usually relies on traditional grass checkerboard technology, which achieves sand fixation and vegetation planting. However, this method requires a large amount of manpower. In these dry 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, which mainly rely on external transportation, resulting in high labor and raw material costs. Therefore, in addition to using grass checkerboard, people have also tried methods such as stone checkerboard, soil checkerboard and plastic grid to fix sand and suppress dust, but these traditional technologies also have problems such as high labor demand, low vegetation survival rate, and high continuous irrigation cost.

[0030] Conical pile 1 is made of high polymer composite material, through adding specific additive and using special processing technology, bionic mist-catching material with similar micro-convex particle structure and spiral feather structure of body surface of desert insect is prepared.Upward anti-pulling barb 2 is arranged on side wall to ensure that device is not easy to slip off after being inserted into ground.

[0031] The horizontal net line 7 is 30° with the horizontal, and the vertical net line 8 is provided with a water collecting groove 801, the width and depth of which are both 0.2 cm. The horizontal net line 7 and the vertical net line 8 are connected through the net line hole 9 on the mist catching net 5, and the distance between the horizontal net line 7 and the vertical net line 8 is 5 cm. The spiral feather piece 11 is wrapped around the vertical net line 8, and the diameter of the vertical net line 8 is 0.6 cm. The mist catching net 5 is made into the form of double-shell four-layer feather-shaped mist catching water collecting net, and the mist catching plate in the mist catching net 5 can be designed into rectangular, triangular and other shapes. The spiral feather piece 11 is fixed on the vertical net line 8 of the double-shell frame, with a width of 2 cm, and together with the particle horizontal net line 7 (30° with the horizontal) with a protrusion 701 on the surface, forms the double-shell four-layer mist catching net 5. The protrusion 701 particle is 0.2 cm high, and the horizontal net line 7 is 0.3 cm in diameter. According to the local wind direction, wind speed and mist flow law, the double-shell four-layer mist catching net 5 is fixed on the lower base plate 3 at a certain angle and distance, forming a multi-layer mist catching array. In the areas with relatively stable wind direction, the mist catching water collecting net / plate can be arranged vertically to the wind direction, and the distance between adjacent mist catching nets 5 is 0.5-1.0 m (or 1.0 m to form a square). The inclination angle of the double-shell four-layer mist catching net 5 is adjusted according to the terrain to maximize the interception of mist and increase the area and efficiency of mist catching. The water collecting groove 801 reserved on the vertical net line 8 in the mist catching net 5 collects the water droplets condensed by the spiral feather piece 11 and the horizontal protrusion 701 particle on the vertical net line under the action of gravity, which is the water collecting unit. The water collecting unit can be made of corrosion-resistant materials, and its shape and size should match the mist catching net 5 to ensure that all water droplets can be effectively collected and smoothly flow to the lower pipe of the double-shell four-layer feather-shaped mist catching net 5.

[0032] Various sensors (wind speed sensor, wind direction sensor, humidity sensor, temperature sensor, light intensity sensor, etc.) can be added in the whole device to monitor environmental parameters and the running state of the device. The data collected by the sensors are 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 according to the received data. At the same time, the control center also has fault diagnosis and alarm functions, which can timely send alarm signals to remind the staff to handle when the sensors detect abnormal data or the device fails.

[0033] Under the test environment, each side of the feather-shaped double-layer fog-collecting net can collect 8g of liquid water in 24 hours, that is, the fog-collecting area of each square (four sides) can collect not less than 24g of fog water in 24 hours.

Under the condition of 8-grade wind speed, the concentration of sand dust in the air in the area within a radius of 10m around the device is reduced by more than 80%, so that the air quality in the area is obviously improved. Under the action of 8-grade wind, the structural displacement of the device does not exceed 10cm, and the connection between the parts should be kept intact; under the action of a Richter 8 earthquake, the device does not collapse and can continue to work normally. Under the condition of normal use and maintenance, the service life of the main parts of the device is more than 50 years.
