Description

Technical Field

[0001] This utility model relates to a seedling shed, specifically a portable graphene seedling shed, and belongs to the field of agricultural equipment technology. Background Technology

[0002] Seedling raising is a crucial step in agricultural production, and its quality directly affects crop growth and final yield. Traditional seedling raising methods mainly include open-field seedling raising, ordinary plastic greenhouse seedling raising, and solar greenhouse seedling raising.

[0003] Open-air seedling cultivation is greatly affected by the natural environment, making it difficult to control temperature and humidity, resulting in a long seedling cycle and unstable survival rate.

[0004] While ordinary plastic greenhouses and solar greenhouses can provide a relatively controllable environment, they are usually large in size and have a fixed structure, making them inconvenient to move and deploy quickly. They are especially unsuitable for home gardening, small-scale experiments, or temporary seedling needs in remote areas.

[0005] In addition, these facilities have limitations in terms of portability, initial investment, and site requirements.

[0006] Temperature control is crucial during seedling cultivation, especially in cold seasons. Traditional seedling heating methods, such as coal-fired water heating, oil-fired air heating, and electric heating wires (blankets), generally suffer from high energy consumption, low safety, environmental pollution (e.g., coal combustion), complex installation, the need for professional operators, and uneven temperature distribution. These problems not only increase seedling costs but also fail to meet the requirements of modern agriculture for energy conservation, environmental protection, and sustainable development.

[0007] In recent years, graphene, as a novel two-dimensional material with excellent thermal conductivity, electrical conductivity, and mechanical properties (The Birth and Characteristics of Graphene Materials), has been increasingly explored for applications in the agricultural field, such as in the production of nano-fertilizers, pesticide synergists, agricultural sensors, and electric heating films.

[0008] However, the current applications of graphene in agriculture are mostly in their initial stages, primarily focusing on combining graphene with existing materials to improve product performance. The technological barriers are relatively low, leading to significant homogenization. Many applications remain at the laboratory research level, lacking fundamental core patents and truly groundbreaking integrated innovative applications. Particularly in the area of ​​portable, multi-functional integrated seedling equipment, products that effectively utilize graphene's properties to address the pain points of existing technologies are still rare.

[0009] Therefore, the market urgently needs a new type of seedling equipment that is simple in structure, easy to carry and deploy, has high heating efficiency, is energy-saving and environmentally friendly, and can provide a stable seedling microenvironment to meet the diversified and refined needs of modern agriculture, especially in scenarios such as home gardening, small farms, scientific research and teaching, and emergency agriculture. Summary of the Invention

[0010] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a portable graphene seedling shed.

[0011] To achieve the above objectives, the present invention adopts the following technical solution:

[0012] A portable graphene seedling greenhouse includes a film covering a frame, the frame being covered with graphene composite support rods, the top ends of several diagonal braces being connected to the top of the graphene composite support rods via hinges, and the bottom ends of the diagonal braces being used to fix them to the ground.

[0013] The inclined tie rod has a scissor-type telescopic structure;

[0014] The graphene composite support rod has a sleeve-type telescopic structure.

[0015] The graphene composite support rod is connected to an external power source to provide heat to the seedling shed in its supported state.

[0016] The aforementioned film is a transparent or semi-transparent flexible film.

[0017] The aforementioned greenhouse is equipped with a temperature sensor, and the control device opens, closes, and adjusts the heating power of the graphene composite support rod based on the feedback from the temperature sensor.

[0018] The aforementioned inclined tie is equipped with several nozzles, which are used to connect to external water supply pipes.

[0019] The aforementioned nozzles are connected in series and / or in parallel via the spray pipeline.

[0021] The aforementioned graphene composite support rod includes a tube with a graphene heating film wrapped around its surface.

[0022] The aforementioned graphene composite support rod includes a tube with graphene conductive and heating fibers wound around its surface.

[0023] The aforementioned graphene composite support rod includes a tube filled with graphene filler.

[0024] Furthermore, the aforementioned pipe materials include carbon fiber pipes, aluminum alloy pipes, and high-strength engineering plastic pipes.

[0025] The advantages of this utility model are:

[0026] This utility model provides a portable graphene seedling greenhouse, which has the following advantages compared with the prior art:

[0027] 1. Highly portable and easy to deploy: The foldable or telescopic tent-like structure, combined with the lightweight properties of graphene composite materials, significantly reduces the overall weight of the seedling shed, making it compact and easy for a single person to quickly set up, store, and move, adapting to various usage scenarios.

[0028] 2. High-efficiency and energy-saving heating: Graphene materials have extremely high electrothermal conversion efficiency, resulting in uniform heating and rapid temperature rise. Compared to traditional heating methods such as electric heating wires, it can significantly save energy, achieving energy savings of 30%-50% for the same heating effect.

[0029] 3. Environmentally friendly: It adopts electric heating, which is clean and produces no pollutants, avoiding the negative environmental impact of traditional coal-fired heating methods, and conforms to the concept of green agricultural development.

[0030] 4. Integrated structure and function: The supporting structure and heating function are cleverly integrated into the graphene composite material rods, which simplifies the overall system design of the seedling shed, reduces the number of parts, reduces potential failure points, and improves space utilization.

[0031] 5. Optimized Seedling Environment: When graphene is electrically heated, it efficiently emits far-infrared rays of specific wavelengths (typically in the 8-14µm band, with 6-14µm considered "life-giving light waves" easily absorbed by plants (graphene's far-infrared properties)). This far-infrared radiation helps promote plant cell activation and metabolism. Combined with uniform and stable temperature control, it can effectively improve seed germination rate and seedling vigor, shortening the seedling cycle. It can increase seedling germination rate by approximately 10% and advance seedling transplanting by 10-15 days.

[0032] 6. Easy to operate and highly integrated: It integrates the main heating and spraying functions, simplifying the user operation process. No complicated installation and debugging are required, providing a one-stop solution for the core environmental control needs in the seedling process.

[0033] 7. Potential cost-effectiveness: Although the initial cost of graphene materials may be relatively higher than that of traditional materials, considering the significant energy-saving effect that leads to reduced operating costs (such as electricity savings), improved seedling efficiency, and the long service life of the material itself (graphene has stable chemical properties and good durability), its overall cost of use is competitive and the long-term benefits are considerable.

[0035] Figure 2 This is a schematic diagram of the seedling shed for Structure 2.

[0036] The markings in the attached diagram have the following meanings: 1. Graphene composite support rod, 2. Diagonal tie rod, 3. Thin film, 4. Nozzle. Detailed Implementation

[0037] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0038] A portable graphene seedling greenhouse consists of a frame and a thin film 3 covering the frame. The film can be connected to the frame using Velcro straps, pre-set slots, snaps, or high-strength nylon ropes to ensure a secure connection and easy disassembly or replacement.

[0039] Preferably, the film is a transparent or semi-transparent flexible film. Materials with high light transmittance (e.g., greater than 85%), good aging resistance, good thermal insulation properties, and lightweight flexibility can be selected. Commonly used films include agricultural-grade films such as EVA (ethylene-vinyl acetate copolymer), PE (polyethylene), and PO (polyolefin), with thicknesses ranging from 0.08 mm to 0.2 mm. For applications requiring higher strength and durability, thin, flexible PC (polycarbonate) sheets can be considered.

[0040] The framework consists of graphene composite support rods 1 and several diagonal bracing members 2.

[0041] Structure 1: A central connector is set at the top of the graphene composite support rod, and multiple hinges are set around the central connector. These hinges are connected to the top of the inclined tie rod to form an umbrella shape.

[0042] The graphene composite support rod is a sleeve-type telescopic structure, and the diagonal bracing is a scissor-type telescopic structure, allowing the canopy to expand or contract in length or width. The structure exhibits good stability when unfolded and minimizes volume when folded. Specifically, both the graphene composite support rod and the diagonal bracing are extendable and retractable, and the diagonal bracing can also be hinged to expand its angle outwards from the top of the graphene composite support rod, creating an open umbrella-like state. When open, the bottom of the diagonal bracing is secured to the ground with anchor bolts such as ground stakes, enhancing wind resistance. For larger portable canopies, lightweight cross cables or ground counterweight designs can be considered.

[0043] Obviously, the frame should have a reliable automatic or manual locking device after all telescopic or folding parts are fully extended to prevent accidental retraction. This could include features such as a ball-operated telescopic mechanism, an external locking ring, or latches at the hinges.

[0044] Structure 2, based on Structure 1, incorporates multiple graphene composite support rods. The tops of these rods are interconnected by graphene composite crossbars, with connections utilizing methods such as snap-fits or threaded tubing. At least two graphene composite support rods are required. The number of diagonal bracing rods can be reduced accordingly. The aim is to expand the film's coverage area, i.e., the coverage area of ​​the seedling shed, by using multiple graphene composite support rods and reducing their height.

[0045] The seedling shed is also equipped with a heating system. The main body of the heating system is a graphene composite support rod (or includes a graphene composite crossbar).

[0046] The graphene composite support rod consists of a graphene heating unit and tubing. Specifically, it can be constructed as follows:

[0047] A. The inner or outer surface of the pipe is coated with a graphene heating coating;

[0048] B. The surface of the pipe is covered with a graphene heating film;

[0049] C. The surface of the pipe is wrapped with graphene conductive and heating fibers;

[0050] D. The inside of the pipe is filled with graphene filler, which gives the entire support rod itself conductive and heat-generating properties.

[0051] Pipes can be made of carbon fiber, aluminum alloy, or high-strength engineering plastics.

[0052] The graphene heating unit is powered by an external power source, generating heat inside the seedling shed. Specifically, a temperature sensor can be installed inside the shed, and a control device can be set up to turn on and off and adjust the heating power of the graphene composite support rod based on the feedback from the temperature sensor. A control switch (thermostat) is also provided, preferably a control panel.

[0053] Users set the target temperature range through a thermostat and monitor the temperature inside the greenhouse in real time through a temperature sensor (such as an NTC thermistor). The system automatically controls and adjusts the heating system to achieve a constant temperature effect.

[0054] Preferably, the control device can also integrate a data storage module, a remote connection module, and a control module, such as controlling via GPRS or Wi-Fi module APP and recording historical data, to further improve the precision of seedling management.

[0055] The power supply can be provided by various means, such as mains power, batteries, or solar panels.

[0056] The seedling shed is also equipped with an irrigation system. The main body of the irrigation system consists of several sprinklers 4 suspended on inclined supports. The sprinklers can be connected in series, parallel, or mixed through spray pipes. When in use, the sprinklers are connected to an external water source through the pipes.

[0057] Specifically, the piping uses lightweight, corrosion-resistant, and flexible plastic hoses (such as PU, PE, or PVC), laid along the frame or inner edge of the seedling shed's roof. Depending on the shed size and crop requirements, one or more micro-sprinklers or drip irrigation heads with good atomization and uniform coverage are installed. The atomizing nozzles create a fine water mist, reducing impact on seedlings and appropriately increasing air humidity. This aims to simplify irrigation operations and provide uniform water supply.

[0058] The pipeline is equipped with a standard quick-connect fitting at the end for easy connection to household water pipes or a small water pump. A manual control valve can be installed at the inlet to control the water flow and adjust the water volume. For more precise control, a solenoid valve can be optionally installed in conjunction with a timer to achieve automatic timed and metered irrigation.

[0059] When using,

[0060] 1. Unfold and secure the frame of the seedling shed on a flat surface.

[0061] 2. Connect the power supply to the electrical interface of the graphene composite support, start the heating component, and set the target temperature as needed (if equipped with a temperature controller).

[0062] 3. Connect the water supply hose to the external water inlet of the greenhouse irrigation system.

[0063] 4. Place the seedling trays or containers containing the sowing substrate and seeds in the seedling shed to begin the seedling process.

[0064] 5. Adjust the temperature according to the needs of the crop and environmental conditions, and irrigate regularly through the sprinkler system.

[0065] After the seedlings are grown, disconnect the power and water supply, empty the seedling trays in the seedling shed, retract the graphene composite support rods and fold the shed body, and put it into a special storage bag for carrying or storage.

[0066] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that the above embodiments do not limit this utility model in any way, and all technical solutions obtained by equivalent substitution or equivalent transformation fall within the protection scope of this utility model.
