Description

Technical Field

[0001] The utility model relates to the technical field of ecological management, in particular to an air film ecological management structure. Background Art

[0002] Alpine regions often have abundant solar and water resources and strong daytime radiation, but due to uneven water distribution, low water temperature, thick permafrost, weak soil water holding capacity, short sunshine time and other reasons, the soil is relatively poor and unsuitable for the growth and development of crops. Therefore, it is of great significance to rationally utilize various resources to improve soil conditions, increase ecological diversity and achieve sustainable agricultural development in alpine regions.

[0003] As a commonly used ecological governance structure, the greenhouse system is widely used in real life. At present, common greenhouse systems usually use polyvinyl chloride (PVC) greenhouse film, polyethylene (PE) greenhouse film, and ethylene-vinyl acetate copolymer greenhouse film to form the greenhouse film. However, in high-altitude and cold areas, there are problems such as low heat collection, poor thermal insulation, and easy breakage. The above-mentioned greenhouse film is difficult to play a role. Moreover, in high-altitude and cold areas, the terrain is undulating, and traditional rigid greenhouse supports are difficult to adapt to the terrain requirements. Therefore, there is still room for improvement. Utility Model Content

[0028] The following is an explanation and description of the technical scheme of the embodiment of the utility model in conjunction with the drawings of the embodiment of the utility model, but the following embodiment is only a preferred embodiment of the utility model, not all. Based on the embodiment in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the utility model.

[0029] In the following description, terms such as "inside", "outside", "up", "down", "left", "right", etc. that indicate directions or positional relationships are only used to facilitate the description of the embodiments and simplify the description, and do not indicate or imply that the referred device or element must have a specific direction, be constructed and operate in a specific direction. Therefore, it should not be understood as a limitation on the present invention.

[0030] See also Figure 1-4 As shown, this embodiment provides an air film ecological management structure, which can be used in complex terrains in high-cold areas, mainly to form a greenhouse system to improve the local ecology of the application area.

[0031] The air film ecological management structure (hereinafter referred to as the management structure) provided in this embodiment mainly includes a flexible support 1, a greenhouse film 2, etc.

[0032] The flexible support 1 is mainly used as a carrier for installing the greenhouse film 2, so that the greenhouse film 2 is surrounded to form an inner space 3 of the greenhouse, so that the inner space 3 of the greenhouse forms a greenhouse system for planting plants.

[0033] like Figure 2 As shown, the flexible bracket 1 includes a plurality of rows of columns 11 arranged in sequence and at intervals, and two layers of twisted rope assemblies arranged vertically at intervals on the columns 11, which are equivalent to forming an upper layer of twisted rope assemblies and a lower layer of twisted rope assemblies, which can be referred to Figure 3 As shown, L1 indicates the upper layer of the rope assembly, and L2 indicates the lower layer of the rope assembly. Each layer of the rope assembly includes a plurality of ropes 12 arranged side by side, and preferably, the ropes 12 in the two layers of the rope assembly extend in substantially the same direction, both extending along the arrangement direction of the columns 11. The ropes 12 can be steel cables, and the ropes 12 are fixed to the top of each column 11.

[0034] The column 11 is preferably a steel structure, used to support the twisted rope 12 and the greenhouse film 2, and the lower end of the column 11 is fixed on the ground or on a hillside.

[0035] The columns 11 and the ropes 12 are used as the flexible support 1 for installing the greenhouse film 2. Since the ropes 12 are flexible, they can be bent according to the terrain, so that the laying of the top film 21 can better adapt to the terrain. For example, it can cross gullies, steep slopes and other complex terrains. Compared with traditional rigid supports, the flexible support 1 has the characteristics of low cost, high clearance, easy installation, etc., and can maximize the utilization of environmental space.

[0036] like Figure 1 As shown, the greenhouse film 2 includes a top film 21 and a side film 22, wherein the top film 21 is laid on the top of the twisted rope assembly, and the side film 22 is arranged around the side of the column 11, and the top film 21 and the side film 22 together form a closed greenhouse space 3, wherein the top film 21 is equivalent to the top wall of the greenhouse space 3, and the side film 22 is the side wall of the greenhouse space 3, and the foundation in the greenhouse space 3 is equivalent to the bottom wall of the greenhouse space 3, thereby forming a closed greenhouse space 3.

[0037] Among them, Figure 1As shown, the top film 21 includes an upper film 211 and a lower film 212, the upper film 211 is fixed on the upper rope assembly, and the lower film 212 is fixed on the lower rope assembly; specifically, along the direction of the rope 12, the upper film 211 is fixed to the rope 12 in the upper rope assembly, and the lower film 212 is fixed to the rope 12 in the lower rope assembly, so that a hollow interlayer 210 is formed between the upper film 211 and the lower film 212, which is equivalent to forming an air layer between the upper film 211 and the lower film 212, so that the top film 21 has good thermal insulation performance, so that the temperature in the greenhouse space 3 can continue to rise during sunshine.

[0038] It is worth noting that the peripheral edges of the upper film 211 and the lower film 212 are fixedly attached together to seal the top film 21 all around, thereby ensuring that the hollow interlayer 210 is in a closed state to achieve a better thermal insulation effect.

[0039] In addition, in this embodiment, the upper film 211, the lower film 212 and the side film 22 are all ETFE air films, which are also called ethylene-tetrafluoroethylene copolymer air films, and have good properties such as light weight, light transmission, heat insulation, corrosion resistance, radiation resistance, and self-cleaning. When used as the greenhouse film 2, the light transmittance of the ETFE air film can reach more than 90%, and it does not block the transmission of ultraviolet rays and other light, which can ensure sufficient daytime radiation in high-cold areas, which is beneficial to the photosynthesis of plants in the greenhouse space 3.

[0040] In addition, in the present embodiment, the portion of the twisted rope 12 between the two adjacent columns 11 droops naturally, thereby causing the middle portions of the upper membrane 211 and the lower membrane 212 to droop naturally, which is beneficial for collecting and recycling the condensed water generated in the space 3 inside the shed. Specifically, the moisture in the space 3 inside the shed will condense to form condensed water when it contacts the bottom wall of the lower membrane 212. Since the middle portion of the lower membrane 212 droops naturally, the condensed water formed on the bottom wall of the lower membrane 212 will flow along the drooping surface of the lower membrane 212 to the low point and finally drip back into the shed, thereby achieving the purpose of recovering the condensed water.

[0041] In order to improve the stability between the upper and lower layers of the rope assembly, in this embodiment, the upper and lower layers of the rope assembly are provided with a rigid support member 14; specifically, the support member 14 can be made of steel; in addition, the support member 14 is a V-shaped rod structure, including two end points (such as Figure 3 14b) and a vertex (as Figure 3 As shown in part 14a in the figure), the two endpoints here can be understood as the endpoints of the two ends of the V-shaped support member 14, and the vertex can be understood as the inflection point of the angle position of the V-shaped rod.

[0042] In addition, the ropes 12 in the upper and lower layers of rope assemblies are staggered in sequence. It can be understood that in the vertical projection direction, the upper and lower layers of ropes 12 are alternately arranged, that is, there is a lower layer of rope 12 between two adjacent ropes 12 in the upper layer.

[0043] The two end points of the V-shaped support member 14 are respectively fixed on two adjacent ropes 12 in one layer of the rope assembly, and the apex is fixed on the rope 12 located between the two adjacent ropes 12 in the other layer of the rope assembly; for example, in this embodiment, as shown in the figure, the V-shaped support members 14 are arranged in reverse order, that is, the apex of one support member 14 faces downward, and the apex of the next support member 14 faces upward.

[0044] In this configuration, by staggeredly arranging the twisted ropes 12 and providing a V-shaped support member 14, a triangular structure is formed between the three twisted ropes 12 connected by the support member 14, which is beneficial to improving local stability.

[0045] In addition, in this embodiment, the flexible bracket 1 also includes a cable 13 arranged on the columns 11 located on both sides; the cable 13 is arranged at an angle, one end of the cable 13 is fixed to the top of the column 11, and the other end is fixed in the foundation, so that the columns 11 on both sides provide reverse support force through the cable 13 to ensure stability.

[0046] In this embodiment, the soil surface of the greenhouse space 3 is covered with a ground film 7 to reduce the evaporation of soil moisture in the greenhouse space 3 and prevent the air humidity in the greenhouse from being too high.

[0047] In addition, in this embodiment, a plurality of heat storage channels 4 for storing water are opened on the foundation of the space 3 in the shed. As an optional implementation, at least one heat storage channel 4 is excavated in the area between two adjacent columns 11. In addition, at least one layer of anti-seepage geomembrane is laid on the surface of the heat storage channel 4. The function of the anti-seepage geomembrane is to prevent the water in the heat storage channel 4 from seeping into the soil.

[0048] The water in the heat storage channel 4 is supplemented by external streams or glacier water. The design of the heat storage channel 4 allows the temperature to continue to rise during the sunshine period. The heat energy converted from the radiant energy is stored in the water storage channel 4 and slowly released at night to slow down the air temperature drop in the greenhouse space 3, thereby improving the temperature regulation. In addition, the water in the heat storage channel 4 can also be used to irrigate the plants in the greenhouse.

[0049] In order to adjust the temperature and humidity in the greenhouse, the management structure provided in this embodiment also includes a spray device 41, a fan 6, a temperature sensor for detecting the temperature of the space 3 in the greenhouse, and a humidity sensor for detecting the humidity of the space 3 in the greenhouse.

[0050] The spray device 41 is arranged in the heat storage channel 4, and can extract water in the heat storage channel 4 for spraying. It is worth noting that the spray device 41 can adopt a circulating spray mechanism. For example, the spraying direction of the spray device 41 is at least partially toward the top of the heat storage channel 4, so that the water sprayed out can fall back into the heat storage channel 4 and be used again.

[0051] The fan 6 can be set at the side membrane 22 to connect the inside and outside of the shed space 3; a plurality of fans 6 can be set, wherein the air outlets of some fans 6 face inside the shed to introduce the air outside the shed into the shed, and the air outlets of other fans 6 face outside the shed to discharge the air inside the shed to the outside. In this way, the two parts of the fans 6 work, one in and one out, to realize ventilation in the shed.

[0052] The fan 6 and the spray device 41 respond to the temperature sensor and the humidity sensor, specifically:

[0053] When the humidity value detected by the humidity sensor is higher than the set humidity setting value, or the temperature value detected by the temperature sensor is higher than the set temperature setting value, it indicates that the humidity or temperature in the greenhouse is too high. At this time, the fan 6 is turned on to achieve internal and external ventilation of the greenhouse space 3, thereby achieving cooling and dehumidification in the greenhouse;

[0054] When the detection value of the humidity sensor is less than or equal to its humidity setting value, the spray device 41 is turned on to spray in the shed, thereby humidifying the space 3 in the shed. In addition, the water sprayed by the spray device 41 can lower the air temperature of the space 3 in the shed and increase the water temperature and dissolved oxygen in the heat storage channel.

[0055] In this way, the air humidity in the greenhouse space 3 is kept within a set range and the temperature in the greenhouse will not be too high.

[0056] In addition, in order to provide additional light for the growth of plants in the greenhouse space 3, the greenhouse space 3 is provided with a fill light device (such as a fill light) and a light sensor for detecting the greenhouse space 3; the fill light device performs fill light in response to the light detection result of the light sensor. Specifically, when the light intensity in the greenhouse detected by the light sensor is lower than the set value, the fill light is turned on to provide fill light.

[0057] In addition, this embodiment also includes a power supply system for providing electric energy, which includes ground photovoltaic 5 and an electric energy storage system. The ground photovoltaic 5 is mainly used to collect solar energy and convert it into electric energy, and store it in the electric energy storage system to power the relevant equipment in this management structure, such as related sensors, fans 6, sprinkler devices 41, fill lighting devices, etc.; the ground photovoltaic 5 is arranged on the outside of the shed space 3; in this embodiment, the power supply system has two functions. First, continuous power supply is achieved through the ground photovoltaic 5 and the electric energy storage system. Under normal circumstances, basically no external power input is required. Second, the photovoltaic panels 51 of the ground photovoltaic 5 can also form a wind protection system to a certain extent to block the influence of strong winds and further improve the safety of the main structure of this scheme.

[0058] In this embodiment, in order to improve the wind-shielding effect of the ground photovoltaic 5, Figure 4 As shown, the ground photovoltaic 5 includes a plurality of photovoltaic panels 51 which are arranged in an inclined manner at intervals from top to bottom, forming a structure similar to a shutter.

[0059] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
