TECHNICAL FIELD

[0002] At present, in the coastal typhoon-prone areas, the strong winds, heavy rains and other disasters brought by typhoons have a serious impact on agricultural production.

In addition, strong winds can also damage agricultural facilities such as plant factories, irrigation systems, etc., affecting the normal operation of agricultural production. The common strong wind speed in the southeast coastal areas is usually between 5-7 levels, with a wind speed range of 8.0-17.1 meters / second (29-61 kilometers / hour), and the specific wind speed will vary depending on the weather conditions (such as typhoons, monsoons, etc.). In addition, the farmland in some northwest arid areas is also disturbed by strong winds due to the lack of adequate protection facilities.

[0003] In addition, the typhoon-prone areas are usually accompanied by high-temperature and humid weather, which will lead to a large use of refrigeration equipment, a sharp increase in water and electricity consumption, and a potential shortage of water and electricity supply, even causing power and water outages. For farms, high-temperature and humid environments can easily lead to the breeding of crop diseases and pests, affecting crop growth and development, and thus leading to reduced yield; high-temperature heat damage can cause physiological disorders in crops, such as blocked male and female differentiation in corn, poor development, and ultimately reduced yield. Rice also has problems such as slow jointing growth and blocked young ear differentiation under high temperature; high-temperature and humid weather can cause excessive soil moisture, leading to waterlogging and waterlogging, affecting crop root respiration and growth.

DETAILED DESCRIPTION

[0021] The embodiments of the present application will be described in detail below with reference to the accompanying drawings, but the present application can be implemented in various different ways as defined and covered by the claims.

[0022] As Figures 1-5 shown, the present application discloses a kind of bionic windproof wall, including multiple windproof wall modules 1, windproof wall module 1 includes 200 wide airtight constant pressure air cavity 10, 15 thick windproof glass 11, air bag 12, nylon net 13, metal net 14, steel column 15, glass fixed sucking disc 16, structural glue 17, batten 18, X-shaped double angle steel 19, concrete 151, longitudinal metal bolt connecting piece 152, transverse metal bolt connecting piece 181, bolt 182.Among them, air bag 12 is air bearing type inflatable structure, uses multilayer composite material, such as adding fiber reinforced material in rubber, can improve the strength and tear resistance of air bag 12, so that it can resist the tensile force and friction force brought by strong wind more.The surface of metal net 14 is commonly used stainless steel net, steel column 15, longitudinal metal bolt connecting piece 152 and X-shaped double angle steel 19, transverse metal bolt connecting piece 181, batten 18 all adopt aluminum alloy material, concrete 151 adopts good fluidity concrete material, more preferably NHPC.

[0023] In the embodiment, the whole windproof wall module 1 is supported by steel column 15, the steel column 15 is cross reinforced and connected by Q355 200x100x8 X-shaped double angle steel 19, the glass fixing frame is installed on the steel column 15, and the six glass fixing sucking discs 16 of the glass fixing frame are fixed by bolts to vertically fix the windproof glass 11.The windproof glass 11 and air bag 12 form airtight constant pressure air cavity 10.Each edge of the windproof glass 11 is edge-coated by batten 18 and structural glue 17.The windproof glass 11 includes vertical windproof glass and horizontal windproof glass, and the vertical windproof glass and the horizontal windproof glass are fixed together by batten 18 buckle connection auxiliary spot welding to form a ring structure.The side of the tempered airtight constant pressure air cavity 10 close to the indoor side is fixed with a metal net 14 with a square hole of 50mm by batten 18 and structural glue 17.The surface at gap 2 is covered by air bag 12 and nylon net 13 with a square hole of 20mm, and the nylon net 13 is outside the air bag 12 and is fixed by batten 18 and structural glue 17 of four sides.

[0024] In the embodiment, the upper and lower windproof wall modules are dovetailed at the upper and lower ends of the steel columns 15 by longitudinal metal bolt connecting pieces 152, and the concrete 151 is poured in the steel columns 15;The left and right windproof wall modules 1 are dovetailed at the ends of the aluminum alloy battens by transverse metal bolt connecting pieces 181, and are reinforced by long 65mm M6 bolts 182.

[0025] In the embodiment, the metal mesh 14 is arranged in the closed constant-pressure air cavity 10 and on the windward side of the windproof glass 11, so as to heat the air in the closed constant-pressure air cavity 10 to increase the inflation degree of the air bag 12, the metal mesh 14 is more simple in material selection, and can be self-adaptively adjusted according to the ambient temperature. Further, the metal mesh 14 can assist in resisting the hot air flow from entering the room, and effectively reduces the indoor temperature.

[0026] The working principle of the embodiment is as follows: In the embodiment, the closed constant-pressure air cavity 10 can ensure the constant pressure in the cavity. When the gap 2 is driven by the air flow to reduce the pressure of the gap 2, the air pressure in the air cavity 10 is greater than the air pressure of the gap 2, the air bag 12 is inflated to resist the strong wind, the greater the wind speed through the gap 2, the smaller the air pressure of the gap 2, and the greater the inflation degree of the air bag 12, so as to realize self-adaptive resistance to strong wind. The air bag 12 is controlled by the material and thickness, such as a flexible and soft composite material with a thin thickness, so that the surface of the air bag 12 is wrinkled under the action of the air flow. Specifically, in a strong wind environment, the flow speed of the air is not uniform on the surface of the air bag 12. According to Bernoulli's principle, when the wind blows through the air bag 12, the surface of the air bag 12 will be subjected to uneven air pressure distribution. This local pressure difference will cause the surface of the air bag 12 to deform and wrinkle. The dynamic disturbance of the wind (the flow of the wind itself is dynamic, which may include turbulent flow or irregular disturbance) will further intensify the air pressure change on the surface of the air bag 12, making it easier to form wrinkles. The air flow is buffered under the blocking and friction of the wrinkles, and the wind speed decreases. The nylon mesh 13 can condense the humid air passing through it into water droplets by using water tension. When the water droplets are distributed on the nylon mesh 13 in a large area, the nylon mesh 13 forms a water film. The nylon meshes 13 on both sides of the same gap 2 of the two wall modules will be bonded together due to water tension. The water film formed by the nylon mesh 13 not only can become an air filter screen (the nylon mesh 13 is regularly cleaned by high-pressure washing with a special cleaning agent), but also can filter sand and dust in the air and resist strong wind. In addition, the nylon mesh 13 can also adjust the humidity of the air, and can consolidate and adjust the inflation form of the air bag 12, realizing multiple technical effects.

[0027] When the temperature is humid and hot, the gas in the closed constant-pressure air cavity 10 expands due to high temperature, so that the air bag 12 is inflated to resist the hot air flow from entering the room. The hot air flow passes through the water film formed by the nylon mesh 13 to enter the room, the water film absorbs the heat of the air flow to evaporate, and the temperature of the air flow decreases, which can effectively adjust the temperature inside and outside the room. Therefore, the nylon mesh 13 imitates the camel nasal cavity surface hair, and the water film formed by the nylon mesh 13 can effectively enhance the windproof and cooling effect of the windproof wall in a humid and hot environment.

[0028] The greater the wind speed, the more humid the air, and the higher the temperature, the more obvious the wind resistance and wind speed reduction ability of the wind-resistant wall.

[0029] The above settings of the present application are the research and derivation of the windproof principle of the camel's nasal cavity: the camel's nasal cavity is covered with fine and dense hair arranged at an angle of 45 degrees, which can absorb water on the hair through water tension and form a natural water film filter. Further, the camel's nasal cavity can also open and close automatically according to the intensity of sand and dust. Before the arrival of sandstorm, the substantial increase of static electricity and ozone concentration in the air will make the circular muscle on both sides of the camel's nasal wings immediately contract, at this time the size of the camel's nasal cavity hole is narrowed to 1 / 5 of the original. The inner wall of the nostril is layered to form a seven-fold structure. These seven "speed bumps" make the hurricane airflow carrying sand particles suddenly slow down to the wind. Research shows that sand particles with a diameter of 10 microns entering the camel's nasal cavity are slowed down by these folds, and the speed of the sand particles is suddenly reduced from 15 meters per second to 0.3 meters, equivalent to changing from a hurricane to a breeze.

[0030] Reference Figures 6-7 To better verify the effect and performance of the windproof wall, the present embodiment adopts a 1:10 micro model for experiment. The experimental conditions are set in the southeast coastal area, where the average temperature in hot weather may be higher, and the highest temperature in some areas may even approach or exceed 40°C, so the high temperature is selected as 40°C. The common strong wind speed in the southeast coastal area is usually between 5-7 levels, and the wind speed range is 8.0-17.1 m / s (29-61 km / h), and the specific wind speed will vary depending on weather conditions (such as typhoon, monsoon, etc.), so the dry low temperature wind condition is selected as 17.3 m / s, the dry high temperature wind condition is selected as 19.2 m / s, and the wet high temperature wind condition is selected as 13.2 m / s. The output wind speed of the experimental equipment remains unchanged, but the measured wind speed is affected by temperature and humidity, so there is a difference. The highest humidity in the southeast coastal area usually occurs in summer, especially in June and July, and the annual average relative humidity in the southeast coastal area is about 80%, so the experimental humidity is controlled at about 80%. During the experiment, an air blower is used to simulate the wind temperature and strong wind with heating at 2 levels and wind force at 1 level. At low temperature, heating is at 0 level and wind force is at 1 level. At high temperature, heating is at 2 levels and wind force is at 1 level. A small watering can is used to control air humidity, with dry conditions at 35% ± 5% and wet conditions at 80% ± 5%. Each group of experiments is observed and recorded after 3 minutes, as shown in Tables 1-3.

[0033] Table 3: Wind speed drop rate behind the wall when the width of gap 2 is 3 cm

[0034] The experimental data can show that the air bag 12 has a significant effect on improving the windproof performance under various climate conditions; the air bag 12 and the nylon net 13 have a significant effect on improving the windproof performance under various climate conditions; and the effect of the air bag 12 and the nylon net 13 on improving the windproof performance under various climate conditions varies with the gap width, and the wider the gap, the lower the wind speed reduction rate.

[0035] Based on the experimental data and analysis, the windproof wall of the present application has the advantages of other existing windproof walls in that it simulates the biological structure of nature, and has excellent performance and unique advantages.

[0036] In the present embodiment, the folds of the air bag 12 can effectively reduce the wind speed by simulating the folds of the camel nasal cavity; the air bag 12 can simulate the camel alar ring muscle to open and close automatically according to the intensity of the wind and sand, and adjust the amount of wind entering the room; the windproof wall should be provided with the air bag 12 and the nylon net 13; in combination with the ventilation, economic benefits and aesthetic effect of the overall building, in combination with the suitable wind speed for crop growth and the ventilation, economic benefits and aesthetic effect of the overall building, the experimental model is converted in proportion, and the suitable gap 2 is 100 mm. The nylon net 13 simulates the camel nasal cavity surface hair, and the water film formed by the water tension of the nylon net 13 can effectively enhance the windproof effect of the windproof wall in a humid and high-temperature environment.

[0037] It adopts lightweight materials and innovative structural design, effectively reducing its own weight, while significantly improving wind resistance. Through passive design strategy, without additional energy consumption, it can realize windproof and building micro-environment regulation. It can automatically adjust related devices according to different wind environment conditions, such as in strong wind, special structure can guide wind flow, reduce wind impact, and also use wind pressure to promote indoor and outdoor air natural circulation; in light wind or no wind, it can also collect natural wind and guide it into the room, creating a comfortable space environment for users at all times.

[0038] In terms of construction, each module adopts prefabricated assembly type structure, connected by bolts, supplemented by buckle connection and auxiliary spot welding, and is very easy to disassemble and reform, effectively reducing construction and maintenance costs. Moreover, in terms of aesthetic design, it breaks through the traditional limitations of combined structure to create a unique and attractive appearance, showing unique artistic beauty and cultural connotation, and has significant application value and broad development prospects, whether it is a temporary building project or a scene with high requirements for building flexibility and aesthetics.
