Description
[01] The present disclosure relates to the technical field of agricultural apparatuses, and in particular to a weed barrier fabric.
[02] The weed barrier fabric, a common ground cover fabric in the field of agriculture, has the functions of controlling weeds from growing, retaining soil moisture and reducing water and soil erosion, and has water permeability, air permeability and thermal retentivity, thereby being widely used in greenhouses.
[03] In winter, the temperature of all areas, especially the north, southwest and northwest areas, decreases substantially. The temperature of the greenhouse is far from meeting the growth requirements of crops in the greenhouse, so heating in the greenhouse is required. At present, the greenhouse is heated by air conditioners, heaters and heating furnaces in most cases, which results in huge energy consumption and non- uniform heating. In winter, crops grow slowly due to the lack of sunlight. The current weed barrier fabrics used in the greenhouse only have a single function and have no function of increasing the temperature of the greenhouse. Moreover, the current weed barrier fabrics are all of a flat structure, and are close to the ground after water is sprayed to the ground, such that air permeability is poor, limiting the use of the weed barrier fabrics.
[04] Therefore, how to solve the above technical problem should be the focus of those skilled in the art.
[05] The objective of the present disclosure is to provide a weed barrier fabric that has a function of heating to promote growth of crops, and has excellent air permeability.
[06] In order to solve the above technical problem, the present disclosure provides the weed barrier fabric. The weed barrier fabric includes:
[07] a bottom layer, a surface layer, a graphene electrothermal film located between the bottom layer and the surface layer, a wire connected to the graphene electrothermal film and a controller used for controlling the graphene electrothermal film to be energized or deenergized, where the graphene electrothermal film includes a metal current-carrying strip, conductive ink containing graphene and an insulating polyester film, and
[08] the bottom layer and the surface layer are provided with protruding structures in regions of the bottom layer and the surface layer not corresponding to the graphene electrothermal film.
[09] Optionally, in the weed barrier fabric, the bottom layer is a calcium-magnesium needle-punched fiber film.
[10] Optionally, in the weed barrier fabric, the surface layer is a polypropylene grass- proof fabric that is formed by weaving a plurality of flat polypropylene filaments.
[11] Optionally, in the weed barrier fabric, the polypropylene grass-proof fabric is a black grass-proof fabric.
[12] Optionally, in the weed barrier fabric, the graphene electrothermal film is strip- shaped, and a plurality of strip-shaped graphene electrothermal films are uniformly distributed between the bottom layer and the surface layer.
[13] Optionally, the weed barrier fabric further includes:
[14] a fastening nail located at an edge of the weed barrier fabric.
[15] Optionally, in the weed barrier fabric, the wire includes a main wire and an auxiliary wire, where one end of the auxiliary wire is connected to the strip-shaped graphene electrothermal film, and the other end of the auxiliary wire is connected to the main wire by means of a buckle.
[16] Optionally, the weed barrier fabric further includes:
[17] a temperature regulator arranged on the main wire, where the temperature regulator includes a housing, an electric energy input interface, an electric energy output interface and a gear capable of regulating and controlling multiple temperature grades.
[18] Optionally, in the weed barrier fabric, the protruding structure has a shape of any one of a hexagon, a square and a circle.
[19] Optionally, the weed barrier fabric further includes:
[20] a temperature sensor connected to the controller.
[21] The weed barrier fabric provided in the present disclosure includes: the bottom layer, the surface layer, the graphene electrothermal film located between the bottom layer and the surface layer, a wire connected to the graphene electrothermal film and the controller used for controlling the energizing and deenergizing of the graphene electrothermal film, where the graphene electrothermal film includes the metal current- carrying strip, the conductive ink containing the graphene and the insulating polyester film; and the bottom layer and the surface layer are provided with the protruding structures in regions of the bottom layer and the surface layer not corresponding to the graphene electrothermal film.
[22] It may be seen that the weed barrier fabric in the present disclosure includes the bottom layer, the surface layer, the graphene electrothermal film and the controller. The controller may control the graphene electrothermal film to be energized or deenergized, when being energized, the graphene electrothermal film generates heat to supply the heat to crops in a greenhouse, and when the heat is not needed, the graphene electrothermal film is controlled to be deenergized, thereby achieving a controllable temperature in the greenhouse; the graphene electrothermal film consumes little power, saves energy, and further may release far infrared rays to promote the growth of the crops and compensate for a shortage of far infrared light due to a lack of light; and in addition, the protruding structures are distributed in regions of the bottom layer and the surface layer not corresponding to the graphene electrothermal film, which enhances air circulation of the weed barrier fabric, thereby enhancing air permeability.
[23] In order to more clearly illustrate technical solutions in the embodiments of the present disclosure or in the prior art, a brief introduction to the accompanying drawings required for the description of the embodiments or the prior art will be provided below. Obviously, the accompanying drawings in the following description are only some of the embodiments of the present disclosure, and those of ordinary skill in the art would also be able to derive other drawings from these drawings without making creative efforts.
[24] FIG. 1 is a structural schematic diagram of a weed barrier fabric provided in the embodiment of the present disclosure;
[25] FIG. 2 is a cross-sectional schematic diagram of the weed barrier fabric provided in the embodiment of the present disclosure; and
[26] FIG. 3 is a schematic diagram in an actual use process of the weed barrier fabric of the present disclosure.
[27] In order to make a person skilled in the art better understand the solution of the present disclosure, the present disclosure is further described in detail below with reference to the accompanying drawings and specific implementations. Apparently, the embodiments described are merely some rather than all of the embodiments of the present disclosure. Based on the embodiments of the present disclosure, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present disclosure.
[28] Many specific details are set forth in the following description to facilitate full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein, similar derivatives may be made by those skilled in the art without departing from the connotation of the present disclosure, and therefore, the present disclosure is not limited by the specific embodiments disclosed below.
[29] As described in the background art, the current weed barrier fabrics used in the greenhouse only have a single function and have no function of increasing temperature of the greenhouse. Moreover, the current weed barrier fabrics are all of a flat structure, and are close to a ground after water is sprayed to the ground, such that air permeability is poor, limiting the use of the weed barrier fabrics.
[30] To this end, the present disclosure provides a weed barrier fabric. FIG. 1 is a structural schematic diagram of the weed barrier fabric provided in the embodiment of the present disclosure. With reference to FIG. 1, the weed barrier fabric includes:
[31] a bottom layer 1, a surface layer 2, a graphene electrothermal film 3 located between the bottom layer 1 and the surface layer 2, a wire 4 connected to the graphene electrothermal film 3 and a controller used for controlling the graphene electrothermal film 3 to be energized or deenergized, where the graphene electrothermal film 3 includes a metal current-carrying strip, conductive ink containing graphene and an insulating polyester film, and
[32] the bottom layer | and the surface layer 2 are provided with protruding structures in regions of the bottom layer 1 and the surface layer 2 not corresponding to the graphene electrothermal film 3.
[33] The graphene electrothermal film 3 may emit 5-14 microns of infrared rays, and the insulating polyester film is generally a polyethylene terephthalate (PET) film. The metal current-carrying strip in the present disclosure is not specifically limited, and may be configured as required. For example, the metal current-carrying strip may be a copper current-carrying strip, an iron current-carrying strip, etc.
[34] The graphene electrothermal film 3 is strip-shaped, and a plurality of graphene 5 electrothermal films 3 are uniformly distributed between the bottom layer 1 and the surface layer 2, thereby achieving an effect of uniform heating. A width of the strip- shaped graphene electrothermal film is 1-3 cm, an interval between adjacent graphene electrothermal films may be 10 cm, and the width of the weed barrier fabric may be regulated according to an actual condition of the greenhouse, which are not specifically limited in the present disclosure. In other embodiments of the present disclosure, the graphene electrothermal film 3 further may be spiral, disc-shaped, S-shaped, etc.
[35] When the temperature in the greenhouse does not reach a temperature threshold, the controller controls the graphene electrothermal film 3 to be energized so as to generate heat. When the temperature reaches the temperature threshold, the controller controls the graphene electrothermal film 3 to be deenergized so as to stop generating heat, thereby preventing overhigh temperature from damaging crops.
[36] FIG. 3 is a schematic diagram in an actual use process of the weed barrier fabric of the present disclosure. The weed barrier fabric covers ridges, and a plurality of weed barrier fabrics are connected together in series.
[37] FIG. 21s a cross-sectional schematic diagram of a cross section AA of the weed barrier fabric. With reference to FIG. 2, the bottom layer 1 and the surface layer 2 are provided with protruding structures, which improve the air permeability of the weed barrier fabric, improves air circulation, and promotes growth of the crops.
[38] The protruding structure has a shape including, but not limited to, any one of a hexagon, a square and a circle.
[39] The bottom layer 1 is configured to reduce downward transfer of the heat generated by the graphene electrothermal film 3 and transfer the heat upwards as much as possible, thereby reducing a loss of the heat, and providing the heat for the greenhouse as much as possible. The bottom layer has the function of thermal insulation.
[40] Preferably, the bottom layer 1 is a calcium-magnesium needle-punched fiber film that has excellent air permeability, water permeability and thermal retentivity, thereby achieving a desirable effect of the thermal retentivity, and improving a heat utilization ratio of the weed barrier fabric, which is not specifically limited in the present disclosure. The bottom layer 1 further may be a foamed plastic thermal insulation material including a foamed board, etc.
[41] The surface layer 2 is configured to transfer the heat generated by the graphene electrothermal film 3 to an upper space, thereby improving the temperature in the greenhouse.
[42] Preferably, the surface layer 2 is a polypropylene grass-proof fabric, where the polypropylene grass-proof fabric is formed by weaving a plurality of flat polypropylene filaments with gaps, such that the polypropylene grass-proof fabric has the desirable air permeability and water permeability, and it is guaranteed that roots of the crops have desirable respiration effect to absorb moisture required for growth, which is not specifically limited in the present disclosure. The surface layer 2 further may be made of other air-permeable and water-permeable wear-resistant materials or weaving materials.
[43] Further, the polypropylene grass-proof fabric is a black grass-proof fabric, which absorbs sunlight, reduces irradiation of the sunlight on weeds below a non-woven fabric, and inhibits the growth of the weeds.
[44] The weed barrier fabric in the present disclosure includes the bottom layer 1, the surface layer 2, the graphene electrothermal film 3 and the controller, where the controller may control the graphene electrothermal film 3 to be energized or deenergized, when the graphene electrothermal film 3 is energized, the graphene electrothermal film 3 generates the heat to supply the heat to the crops in the greenhouse, and when the heat is not needed, the graphene electrothermal film 3 is controlled to be deenergized, thereby achieving the controllable temperature in the greenhouse; the graphene electrothermal film 3 consumes little power and saves energy, and the graphene electrothermal film 3 further may release far infrared rays to promote the growth of the crops and compensate for a shortage of far infrared light due to a lack of light; and in addition, the protruding structures are distributed in regions of the bottom layer 1 and the surface layer 2 not corresponding to the graphene electrothermal film 3, which enhances the air circulation of the weed barrier fabric, thereby enhancing the air permeability.
[45] In one embodiment of the present disclosure, when the weed barrier fabric includes a plurality of strip-shaped graphene electrothermal films, and the wire includes a main wire and an auxiliary wire, where one end of the auxiliary wire is connected to the strip-shaped graphene electrothermal film, and the other end of the auxiliary wire is connected to the main wire by means of a buckle.
[46] When a heating degree of the weed barrier fabric needs to be regulated, connection or disconnection of the auxiliary wire and the main wire may be controlled by closing or opening the buckle, so as to regulate the number of the graphene electrothermal film performing heating. When one buckle is closed, the strip-shaped graphene corresponding to the buckle performs heating, and when one buckle is disconnected, the strip-shaped graphene corresponding to the buckle stops heating. Understandably, the number of the auxiliary wire is equal to that of the strip-shaped graphene.
[47] Further, the weed barrier fabric further includes:
[48] a temperature regulator arranged on the main wire, where the temperature regulator includes a housing, an electric energy input interface, an electric energy output interface and a gear capable of regulating and controlling multiple temperature grades. The temperature regulator is connected to the main wire in series. The number of the temperature grade is not specifically limited in the present disclosure, and may be, for example, 2, 5, 6, etc. The higher the gear is, the higher the temperature grade is, and the higher heating power is. That is, the weed barrier fabric in the present disclosure may not only regulate the number of the graphene electrothermal film performing heating, but also regulate the heating power of the heating graphene electrothermal film, which better keeps the temperature in the greenhouse stable, and is more convenient and intelligent.
[49] Optionally, in one embodiment of the present disclosure, the weed barrier fabric further includes:
[50] a fastening nail located at an edge of the weed barrier fabric.
[51] The weed barrier fabric is fixed on ground by means of the fastening nail, thereby avoiding curling and wrinkling when the weed barrier fabric is subjected to an external force. [S2] On the basis of any one of the embodiments mentioned above, in one embodiment of the present disclosure, the weed barrier fabric further includes: [S3] atemperature sensor connected to the controller. [S4] The temperature sensor is used for acquiring the temperature in the greenhouse and sending the temperature to the controller, such that the controller may conveniently control the graphene electrothermal film 3 to be energized or deenergized.
[55] The various embodiments in the specification are described in a progressive manner, each embodiment focuses on the difference from other embodiments, and it is sufficient to refer to one another for the same and similar parts among the various embodiments. Since a device disclosed in the embodiments corresponds to a method disclosed in the embodiments, its description is relatively simple, and relevant contents may be seen from partial description of the method.
[56] The weed barrier fabric provided in the present disclosure is introduced in detail above. Specific embodiments are used for illustrating principles and implementations of the present disclosure herein. The description of the embodiments above is only used for helping understand the method and its core concept of the present disclosure. It should be noted that several improvements and modifications may also be made by those of ordinary skill in the art without departing from the principles of the present disclosure, which also fall within the scope of protection of the present disclosure.
