Description

Technical Field

[0001] This utility model belongs to the field of vegetable greenhouse heating and insulation technology, and in particular relates to a solar vegetable greenhouse with an electric auxiliary heating mechanism. Background Technology

[0002] A vegetable greenhouse is a frame-and-film structure with excellent heat preservation properties. This structure forms a greenhouse space, effectively preventing the loss of carbon dioxide and maintaining good heat preservation, which allows people to eat out-of-season vegetables.

[0003] In the operation of existing vegetable greenhouses, solar energy is used to power electric auxiliary heating mechanisms in order to control the temperature inside the greenhouse. These mechanisms heat the space inside the greenhouse, but due to the low thermal conductivity of air, the heating efficiency of the electric auxiliary heating mechanisms is relatively low.

[0004] To address the aforementioned technical problems, the applicant searched for some existing technologies to improve heating efficiency. For example, patent publication number CN220875265U describes a method where a heating cabinet heats water in a tank, and the heat is transferred to the surrounding soil through heat-conducting pipes buried in the soil. The water, having lost its heat, is then returned to the tank via a return pipe for reheating. This cycle ensures a continuous flow of heat from the hot water into the soil. However, the applicant's analysis reveals a drawback: the heat-conducting pipes buried beneath the ground may break and leak during use. Hot water leakage would cause the surrounding soil temperature to rise, and the hot water would slowly seep to the soil surface, potentially negatively impacting vegetable growth, interfering with their normal growth cycle, and leading to stunted growth or premature aging. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a solar-powered vegetable greenhouse equipped with an electric auxiliary heating mechanism, thereby solving the technical problem that hot water leakage can cause the surrounding soil temperature to rise, which in turn has an adverse effect on vegetable growth.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A solar-powered vegetable greenhouse equipped with an electric auxiliary heating mechanism includes a greenhouse body, a solar cell, a water storage tank, a water pump, a heating source, an inlet pipe, a pre-buried connecting pipe, and an outlet pipe. The greenhouse also includes:

[0008] A cover plate, which is pre-buried in the soil and covers the pre-buried pipe, wherein the area of ​​the cover plate is larger than the area of ​​the pre-buried pipe.

[0009] As a preferred embodiment of the above technical solution, a limiting plate is provided on each of the four sides of the bottom of the cover plate.

[0010] As a preferred embodiment of the above technical solution, the height of the limiting plate is greater than the diameter of the pre-embedded pipe.

[0011] As a preferred embodiment of the above technical solution, the water inlet pipe is provided with a plurality of auxiliary mechanisms, the auxiliary mechanisms including:

[0012] A rotating rod, which passes through the water inlet pipe and is perpendicular to the water inlet pipe;

[0013] A turbine is installed around the rotating rod. The turbine is located inside the water inlet pipe. When water passes through the water inlet pipe, it causes the turbine to rotate, which in turn causes the rotating rod to rotate.

[0014] Fan blades are installed around the rotating rod and are located outside the water inlet pipe.

[0015] As a preferred embodiment of the above technical solution, the water inlet pipe is connected to a water spray pipe via several connecting pipes, an electrically controlled valve is installed on the connecting pipes, and several nozzles are installed on the water spray pipe.

[0016] The beneficial effects of this utility model are as follows:

[0017] 1. In this utility model, a cover plate is placed on the pre-buried pipe. If the pre-buried pipe is damaged and leaks, hot water will flow out from the pre-buried pipe. Since the pre-buried pipe is covered with a cover plate, the cover plate can prevent hot water from directly penetrating to the soil surface, reduce the direct impact of hot water on the soil surface, effectively prevent hot water from penetrating to the soil surface and affecting the growth of vegetables, avoid interfering with the normal growth cycle of vegetables, and avoid slow growth or premature aging of vegetables.

[0018] 2. In this utility model, the limiting plate can restrict the direction of water seepage in the pre-buried pipe when it leaks, effectively preventing the leaked hot water from seeping into the soil surface, further preventing the seeping hot water from affecting the growth of vegetables, preventing the leaked hot water from interfering with the normal growth cycle of vegetables, and preventing the vegetables from growing slowly or aging prematurely.

[0019] 3. In this utility model, the water inlet pipe conducts heat through air. After the pre-buried pipe heats up, the soil around it gradually warms up. Since the cover plate is placed on the pre-buried pipe, the surface temperature of the cover plate also gradually increases. Because the cover plate has a large contact area with the soil, the soil warming effect of the cover plate is better than that of the pre-buried pipe, thereby enhancing the heating effect on the temperature inside the greenhouse and helping the vegetables grow.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figure 1 and Figure 2 As shown, a solar-powered vegetable greenhouse equipped with an electric auxiliary heating mechanism includes a greenhouse body 1, a solar cell body 2, a water storage tank 3, a water pump 4, a heating source 5, a water inlet pipe 6, a pre-buried pipe 7, a connecting pipe 9, and a return water pipe 10. The greenhouse also includes:

[0028] Cover plate 8 is embedded in the soil and covers the pre-buried pipe 7. The area of ​​cover plate 8 is larger than the area of ​​the pre-buried pipe 7.

[0029] In one embodiment, the inlet pipe 6 is connected to the water pump 4, the pre-embedded pipe 7 is connected to the other end of the inlet pipe 6 via the connecting pipe 9, and the return pipe 10 is connected to the other end of the pre-embedded pipe 7, with the end of the return pipe 10 extending into the water storage tank 3. The solar panel 2 supplies power to the water pump 4 and the heating source 5, which can be a heater or a component capable of heating water. Additionally, the solar panel 2 is connected to a battery 11, which also supplies power to the water pump 4 and the heating source 5. The water pump 4, the heating source 5, and the battery 11 are connected to an external control unit. The external control unit can be a mobile APP or a computer control terminal, which controls the start and stop of the water pump 4, the heating source 5 and the battery 11. The cover plate 8 can be made of aluminum and coated with anti-corrosion coating, such as epoxy resin or polyurethane coating. These coatings can form a strong protective layer on the aluminum surface, preventing the intrusion of water and oxygen, thereby improving the corrosion resistance of the cover plate 8. In addition, the greenhouse body 1 is equipped with several drainage channels 12. The drainage channels 12 are inclined, and their inclined ends face the water storage tank 3.

[0030] In practical application, this embodiment uses an external control unit to control the heating source 5 to heat the water in the water storage tank 3. When the water reaches a predetermined temperature—enough to heat the interior of the greenhouse 1—the water pump 4 is then controlled to pump water into the inlet pipe 6. As the hot water enters the inlet pipe 6, the surrounding air temperature gradually rises. Through air conduction, this heats the interior of the greenhouse 1. The water in the inlet pipe 6 then flows through the connecting pipe 9 into the pre-buried pipe 7 below ground level a. The soil around the pre-buried pipe 7 gradually warms up, further enhancing the temperature of the greenhouse. Pipe 6 conducts heat through the air, which improves the heating effect inside the greenhouse body 1 and provides a better production environment for vegetables. If the pre-buried pipe 7 is damaged and leaks, hot water will flow out from the pre-buried pipe 7. Since the pre-buried pipe 7 is covered with a cover plate 8, and the area of ​​the cover plate 8 is larger than the laying area of ​​the pre-buried pipe 7, the cover plate 8 can prevent hot water from directly penetrating to the soil surface, reduce the direct impact of hot water on the soil surface, effectively prevent hot water from penetrating to the soil surface and affecting the growth of vegetables, avoid interfering with the normal growth cycle of vegetables, and prevent vegetables from growing slowly or aging prematurely.

[0031] After hot water enters the pre-buried pipe 7, the surface of the pre-buried pipe 7 and the surrounding soil gradually heat up. Since the cover plate 8 is placed on the pre-buried pipe 7, the surface temperature of the cover plate 8 also gradually increases. Because the cover plate 8 has a large contact area with the soil, the soil temperature rises better with the cover plate 8 than with the pre-buried pipe 7, thereby enhancing the heating effect on the temperature inside the greenhouse body 1, which is beneficial to vegetable growth.

[0032] Furthermore, a limiting plate 81 is provided on each of the four sides of the bottom of the cover plate 8.

[0033] In one embodiment, the limiting plate 81 is also made of aluminum and its surface is coated with an anti-corrosion coating.

[0034] In practical application, the limiting plate 81 isolates the soil around the pre-buried pipe 7, which can effectively limit the direction of water seepage when the pre-buried pipe 7 leaks, effectively prevent the leaked hot water from seeping into the soil surface, further prevent the seeping hot water from affecting the growth of vegetables, prevent the leaked hot water from interfering with the normal growth cycle of vegetables, and prevent the vegetables from growing slowly or aging prematurely.

[0035] Furthermore, the height of the limiting plate 81 is greater than the diameter of the embedded pipe 7.

[0036] In practical applications, this embodiment can further restrict the direction of hot water infiltration, further prevent leaked hot water from seeping into the soil surface, further prevent the infiltrated hot water from affecting the growth of vegetables, prevent leaked hot water from interfering with the normal growth cycle of vegetables, and prevent vegetables from growing slowly or aging prematurely.

[0037] like Figure 3 and Figure 4 As shown, the water inlet pipe 6 is equipped with several auxiliary mechanisms 14, which include:

[0038] Rotating rod 142 passes through water inlet pipe 6 and is perpendicular to water inlet pipe 6;

[0039] Turbine 141 and rotating rod 142 are mounted on the periphery of turbine 141. Turbine 141 is located inside water inlet pipe 6. When water passes through water inlet pipe 6, turbine 141 rotates, causing rotating rod 142 to rotate.

[0040] Fan blade 143 is installed around the rotating rod 142. Fan blade 143 is located outside the water inlet pipe 6.

[0041] In practical application, when hot water enters the inlet pipe 6, the flow of water causes the turbine 141 to rotate, which in turn causes the rotating rod 142 to drive the fan blades 143 to rotate. The rotation of the fan blades 143 will blow hot air to flow rapidly. The rotation of several fan blades 143 will cause the hot air inside the greenhouse body 1 to circulate rapidly, thereby accelerating the temperature rise inside the greenhouse body 1. Combined with the heat conduction of the pre-embedded pipe 7 and the cover plate 8, the heating efficiency is further improved, and the heating effect inside the greenhouse body 1 is enhanced, which is conducive to vegetable growth.

[0042] like Figures 1-4 As shown, a water inlet pipe 6 is connected to a water spray pipe 13 via several connecting pipes 131. An electric control valve 132 is installed on the connecting pipe 131, and several nozzles 133 are installed on the water spray pipe 13.

[0043] In one embodiment, the solenoid valve 132 is connected to an external control unit, and the external control unit controls the opening and closing of the solenoid valve 132.

[0044] In practical application, the water in the water storage tank 3 can be used not only to heat the temperature inside the greenhouse body 1, but also when the temperature inside the greenhouse body 1 does not need to be heated and the water is at room temperature. The water pump 4 is controlled by the external control unit to pump water into the water inlet pipe 6, and at the same time, several electrically controlled valves 132 are opened to allow water to enter the spray pipe 13 through the connecting pipe 131, and finally spray out from the nozzle 133 to water the vegetables.

[0045] Working principle: If the pre-buried pipe 7 is damaged and leaks, hot water will flow out from the pre-buried pipe 7. Since the pre-buried pipe 7 is covered by a cover plate 8 and a limiting plate 81 on the cover plate 8, the cover plate 8 can prevent hot water from directly penetrating to the soil surface, and the limiting plate 81 can restrict the direction of water penetration when the pre-buried pipe 7 leaks, thereby reducing the direct impact of hot water on the soil surface, effectively preventing hot water from penetrating to the soil surface and affecting the growth of vegetables, avoiding interference with the normal growth cycle of vegetables, and preventing vegetables from growing slowly or aging prematurely.

[0046] 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 this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
