Description

Technical Field

[0001] The invention relates to the field of heat preservation greenhouses, in particular to an electrically heated solar greenhouse. Background Art

[0002] Greenhouses are mainly used in cold winter areas or areas with large temperature differences. The constant temperature characteristics of greenhouses are used to store temperature and grow summer vegetables or fruits. However, there is a problem of heat loss in greenhouses, especially for plants planted at the edge of the greenhouse. It is very easy for the plants to die due to unstable temperature. Therefore, it is necessary to design a greenhouse with a constant temperature that can keep warm during the cold period at night.

[0003] Therefore, we propose an electrically heated solar greenhouse to solve the above problems. Summary of the invention

[0004] The purpose of the present invention is to provide an electrically heated solar greenhouse to solve the problems raised in the above-mentioned background technology. The technical solution of the present invention aims at the technical problem that the existing technical solution is too single, and provides a solution that is significantly different from the existing technology.

[0005] To achieve the above object, the present invention provides the following technical solutions: An electrically heated solar greenhouse comprises a greenhouse, wherein a through groove is provided on the top of the greenhouse, the upper surface of the greenhouse is covered with a heat-insulating cloth, a heat-absorbing component is installed on the upper surface of the heat-insulating cloth, and a winder is arranged inside the greenhouse.

[0006] In a further embodiment, a pull rope is connected to an edge of one side of the insulation cloth away from the through groove, and the pull rope is made of elastic material and connected to the bottom of the greenhouse.

[0007] In a further embodiment, the insulation cloth is made of transparent polyethylene.

[0008] In a further embodiment, the winder is connected to the insulation cloth via a drawstring passing through a through slot, and the width of the through slot can accommodate and pass through two layers of insulation cloth.

[0009] In a further embodiment, the heat absorption component includes a transparent hose, a telescopic rod, thermal insulation cotton and a heat absorption sheet. The transparent hose and the telescopic rod are installed on the upper surface of the insulation cloth. The outer circle of the transparent hose is adhered with thermal insulation cotton, and a heat absorption sheet is arranged inside the transparent hose.

[0010] In a further embodiment, the outer surface of the heat absorbing sheet is coated with a spectrally selective absorption coating.

[0011] In a further embodiment, the transparent hose and the telescopic rod are both made of transparent materials, and both are filled with paraffin.

[0012] Compared with the prior art, the present invention has the following beneficial effects: The present invention adopts a structure that absorbs heat energy during the day and releases heat energy at night, and uses paraffin as the main energy storage material. When the heat absorption component absorbs heat energy, the paraffin inside the transparent hose can be quickly melted, so that the paraffin appears in a transparent state and can transmit light normally, without affecting the light transmission performance of the entire greenhouse structure. At the same time, the insulation cloth and the heat absorption component are stored inside the greenhouse at around 3 pm, which can not only keep the insulation cloth and the heat absorption component warm, but also avoid the scattering of light by the insulation cloth as the sunlight weakens, thereby improving the light regulation in the greenhouse. When the insulation cloth is opened in the morning, it can also weaken the strong sunlight on the vegetation. At the same time, the heat-insulating cloth of the present invention can be unfolded at night to heat and insulate the top of the greenhouse, and slowly release heat energy through paraffin, so as to achieve the effect of storing energy during the day and releasing heat energy at night.

[0018] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] Example 1: Please refer to Figure 1-3 In an embodiment of the present invention, an electrically heated solar greenhouse comprises a greenhouse 1, a through groove 2 is provided on the top of the greenhouse 1, the upper surface of the greenhouse 1 is covered with a heat-insulating cloth 3, a heat-absorbing component 5 is installed on the upper surface of the heat-insulating cloth 3, a winder 6 is arranged inside the greenhouse 1, and a pull-back rope 4 is connected to the edge of the side of the heat-insulating cloth 3 away from the through groove 2. The pull-back rope 4 is made of elastic material and is connected to the bottom of the greenhouse 1. The pull-back rope 4 can allow the heat-insulating cloth 3 to unfold outward from a vertical state in the greenhouse 1 to a flat state, thereby ensuring the recoverability of the heat-insulating cloth 3.

[0021] An electric heating air conditioner can be used inside the greenhouse 1 to continuously heat the interior of the greenhouse.

[0022] Example 2: Please refer to Figure 1-3The difference from Example 1 is that the insulation cloth 3 is made of transparent polyethylene. The insulation cloth 3 is made of polyethylene, which can not only achieve the effect of transparency and non-refractive, but also have a certain insulation effect.

[0023] The winder 6 is connected to the insulation cloth 3 through a pull rope passing through the through slot 2. The width of the through slot 2 can accommodate and pass through two layers of insulation cloth 3. The winder 6 mainly pulls the insulation cloth 3 inward, and can pull the insulation cloth 3 downward to a vertical state. At the same time, the insulation cloth 3 can also cover the through slot 2 to a certain extent to avoid connection with the inside of the Dapeng 1 and the outside world.

[0024] Example 3: Please refer to Figure 1-3 , which is different from Example 1, is that the heat absorption component 5 includes a transparent hose 501, a telescopic rod 502, a heat-insulating cotton 503 and a heat-absorbing sheet 504. The upper surface of the heat-insulating cloth 3 is installed with a transparent hose 501 and a telescopic rod 502. The outer ring of the transparent hose 501 is attached with a heat-insulating cotton 503. The inside of the transparent hose 501 is provided with a heat-absorbing sheet 504. The heat absorption component 5 can absorb heat energy from solar energy. The inside of the transparent hose 501 and the telescopic rod 502 are filled with paraffin. After the paraffin absorbs the heat energy, After the telescopic rod 502 is melted into a transparent state, since the interior of the telescopic rod 502 is completely filled with paraffin wax, there is no air inside the telescopic rod 502 after the paraffin wax is melted. As a result, the volume of the paraffin wax shrinks after it melts, and the transparent hose 501 is pulled downward, from a conical structure to a flat structure, so that the entire transparent hose 501 is insulated by the thermal insulation cotton 503 on the side. When the temperature drops, the paraffin wax will slowly solidify into a solid state, and at the same time, its volume will expand, so that the flat transparent hose 501 will return to a spiral state.

[0025] The outer surface of the heat absorbing sheet 504 is coated with a spectrally selective absorption coating. The heat absorbing sheet 504 can be made of a sheet of glass. The spectrally selective absorption coating is applied on the surface to absorb the solar spectrum to heat the paraffin inside.

[0026] The transparent hose 501 and the telescopic rod 502 are both made of transparent material, and both are filled with paraffin wax. The transparent hose 501 and the telescopic rod 502 are made of transparent material so that the paraffin wax inside can be exposed to sunlight from the outside. The working principle of the present invention is: When it is sunny, the sun can pass through the transparent greenhouse 1 and the insulation cloth 3 to illuminate the plants inside, and can also heat the heat absorption component 5. When the heat absorption component 5 absorbs enough heat energy, the winder 6 can be turned on at around three o'clock in the afternoon to store the insulation cloth 3 that has fully absorbed the heat energy into the greenhouse 1. Under the action of the reverse pull rope 4, the end of the insulation cloth 3 is located at the through groove 2, and the entire insulation cloth 3 is folded in half and hung upside down in the middle of the greenhouse 1. At this time, according to the temperature in the greenhouse, the heat is well preserved. When the temperature is lower at night, the winder 6 is used again to allow the insulation cloth 3 to cover the upper surface of the greenhouse 1 again to keep the outside of the greenhouse warm.

[0027] The heat absorption component 5 can absorb heat energy from solar energy. The transparent hose 501 and the telescopic rod 502 are filled with paraffin wax. After absorbing heat energy, the paraffin wax will melt into a transparent state. Since the telescopic rod 502 is completely filled with paraffin wax, after the paraffin wax melts, there is no air inside the telescopic rod 502. The volume of the paraffin wax will shrink after it melts, and the transparent hose 501 will be pulled downward from a conical structure to a flat structure, so that the entire transparent hose 501 is insulated by the thermal insulation cotton 503 on the side. When the temperature drops, the paraffin wax will slowly solidify into a solid state and expand in volume, so that the flat transparent hose 501 will return to a spiral state.
