Description

Technical Field

[0001] This application belongs to the field of greenhouse heating technology, specifically a heating device for greenhouse cultivation. Background Technology

[0002] Greenhouse cultivation is an agricultural production method that uses specific facilities to create a suitable growing environment for crops. By building greenhouses and covering them with light-transmitting materials, the indoor temperature can be effectively maintained and the crops can be protected from adverse external climates. The greenhouses can be equipped with irrigation, ventilation, and shading systems to precisely control water, air circulation, and light conditions. Based on the different growth needs of various crops, people can scientifically arrange planting varieties and crop rotations, and carry out refined management in a relatively enclosed space to achieve off-season growth of crops, increase yield and quality, thereby increasing agricultural production efficiency and enriching the supply of agricultural products.

[0003] For example, the utility model patent with announcement number CN219679352U discloses an energy-saving heating device for greenhouses, including a shell, a hot water tank, a cold water tank, and a temperature-conducting pipe. The inner wall of the shell is provided with an insulation layer for heat preservation of the greenhouse. The temperature-conducting pipe is provided on the side of the insulation layer away from the shell. The outside of the shell is provided with a temperature-regulating component for temperature control. This utility model can automatically heat or cool the greenhouse. The use of the temperature-conducting pipe on the inner wall of the shell can ensure uniform temperature. The use of solar panels can provide a certain amount of electricity to the mechanical components, thus saving resources.

[0004] However, in actual use, it was discovered that the device transmits the temperature released by the heat pipe to the inside of the greenhouse through an aluminum plate to achieve temperature control, automatic heating or cooling.

[0005] However, the aluminum plate is installed on the inner wall of the shell, which causes a significant temperature difference between the part near the inner wall of the shell and the middle of the shell when the aluminum plate releases heat. This makes it impossible for the temperature released by the aluminum plate to be evenly distributed in the shell, affecting the overall temperature balance in the greenhouse. Therefore, a heating device for greenhouse cultivation is provided. Utility Model Content

[0006] The purpose of this application is to provide a heating device for greenhouse cultivation in order to solve the problems mentioned above.

[0007] The technical solution adopted in this application is as follows: A heating device for greenhouse cultivation includes a greenhouse frame. A rectangular mounting shell is provided inside the greenhouse frame. A connecting sealing plate is fixedly installed on the top surface of the rectangular mounting shell by bolts. Multiple exhaust fans are installed in an array at equal intervals on the top surface of the connecting sealing plate. An S-shaped conveying aluminum pipe is fixedly installed inside the rectangular mounting shell. The left and right ends of the S-shaped conveying aluminum pipe extend to the outside of the rectangular mounting shell, respectively. A hot water supply pipe is fixedly installed on the right end of the S-shaped conveying aluminum pipe, and a circulation pipe is fixedly installed on the left end of the S-shaped conveying aluminum pipe. Multiple L-shaped exhaust pipes are fixedly installed on the left and right sides of the rectangular mounting shell, and exhaust holes are opened on the outer surface of the multiple L-shaped exhaust pipes.

[0008] In a preferred embodiment, a plurality of heat-absorbing aluminum plates are fixedly installed inside the rectangular mounting housing below the S-shaped conveying aluminum tube, and the top surfaces of the plurality of heat-absorbing aluminum plates are in contact with the outer surface of the S-shaped conveying aluminum tube.

[0009] In a preferred embodiment, an electrically controlled valve is fixedly installed on the outer surface of the hot water supply pipe.

[0012] In a preferred embodiment, the rectangular mounting housing is made of aluminum alloy.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:

[0014] 1. In this application, due to the adoption of the above-mentioned scheme, the exhaust fan is activated, and the hot gas is discharged through the L-shaped exhaust pipe under its action. At the same time, the triangular guide plate on the bottom surface of the rectangular mounting shell changes the air flow path, prevents local air stagnation, and promotes the heat emitted by the S-shaped conveying aluminum pipe to be fully distributed in the shell. Then, it is discharged through the L-shaped exhaust pipe and exhaust vent, allowing the hot air to disperse into the greenhouse and promote uniform heating of the air. Through the coordinated arrangement of the S-shaped conveying aluminum pipe, heat-absorbing aluminum plate, L-shaped exhaust pipe and exhaust vent, this device can efficiently perform heat exchange between hot water and air, so that the hot air is evenly dispersed into the greenhouse and the temperature inside the greenhouse is more uniform.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the embodiments of this application. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0020] refer to Figure 1 , Figure 2 and Figure 3 A heating device for greenhouse cultivation includes a greenhouse frame 1. Inside the greenhouse frame 1 is a rectangular mounting shell 2 made of aluminum alloy. Multiple fixed support rods 13 are fixedly installed on the left and right sides of the rectangular mounting shell 2, with the ends of the support rods 13 furthest from the rectangular mounting shell 2 fixed to the main internal frame of the greenhouse frame 1. The aluminum alloy rectangular mounting shell 2 is lightweight, high-strength, and corrosion-resistant, ensuring structural stability while extending the device's service life. The fixed support rods 13 ensure a reliable connection between the rectangular mounting shell 2 and the main frame of the greenhouse frame 1, guaranteeing the heating device is firmly installed inside the greenhouse, preventing shaking or displacement, and providing a solid foundation for its stable operation.

[0021] refer to Figure 1 , Figure 2 and Figure 3The top surface of the rectangular mounting shell 2 is fixed with a connecting sealing plate 3 by bolts. Multiple exhaust fans 4 are installed in an evenly spaced array on the top surface of the connecting sealing plate 3. The bolt-fixed connecting sealing plate 3 facilitates the later inspection and maintenance of the exhaust fans 4 or the components inside the rectangular mounting shell, and can be disassembled at any time. The evenly spaced array of exhaust fans 4 can evenly exhaust the hot air generated inside the rectangular mounting shell 2 into the greenhouse, accelerate the diffusion of hot air in the greenhouse, help improve the temperature uniformity inside the greenhouse, and provide a more suitable and balanced temperature environment for crops.

[0022] refer to Figure 2 , Figure 3 An S-shaped aluminum conveying pipe 5 is fixedly installed inside the rectangular mounting housing 2. The left and right ends of the S-shaped aluminum conveying pipe 5 extend to the outside of the rectangular mounting housing 2. A hot water supply pipe 6 is fixedly installed at the right end of the S-shaped aluminum conveying pipe 5, and an electrically controlled valve 11 is fixedly installed on the outer surface of the hot water supply pipe 6. A circulation pipe 7 is fixedly installed at the left end of the S-shaped aluminum conveying pipe 5. The hot water supply pipe 6 is connected to an external high-pressure pump, allowing externally heated hot water to enter the interior of the S-shaped aluminum conveying pipe 5. The S-shaped aluminum conveying pipe 5 significantly increases the contact area between the hot water and the outside air. Combined with the excellent thermal conductivity of aluminum, the heat carried by the hot water can be transferred to the surrounding environment more efficiently. The electrically controlled valve 11 can precisely control the flow rate and time of hot water entering the S-shaped aluminum conveying pipe 5, facilitating flexible adjustment of the heating intensity according to the actual temperature requirements inside the greenhouse. The circulation pipe 7 can return the used hot water to the heating equipment, realizing the recycling of water resources and heat, improving energy utilization, and reducing operating costs.

[0023] refer to Figure 1 , Figure 2 and Figure 3 Multiple L-shaped exhaust pipes 8 are fixedly installed on the left and right sides of the rectangular mounting shell 2, and exhaust holes 9 are opened on the outer surface of the multiple L-shaped exhaust pipes 8. The L-shaped exhaust pipes 8 can guide hot air to be discharged in a specific direction. In conjunction with the exhaust holes 9, the hot air can enter the greenhouse in a more dispersed manner, avoiding the concentrated discharge of hot air that would cause the local temperature to be too high or too low. This further promotes the uniform heating of the air in the greenhouse, optimizes the overall heating effect, and ensures that all areas of the crops can receive a suitable temperature.

[0024] refer to Figure 2 , Figure 3 A triangular guide plate 12 is fixedly installed on the bottom surface of the rectangular mounting shell 2. The triangular guide plate 12 can change the air flow path inside the rectangular mounting shell 2, and then deliver hot gas to the greenhouse more evenly through the exhaust fan 4 and L-shaped exhaust pipe 8.

[0025] refer to Figure 2 , Figure 3 Inside the rectangular mounting housing 2, below the S-shaped conveying aluminum pipe 5, multiple heat-absorbing aluminum plates 10 are fixedly installed, and the top surfaces of the multiple heat-absorbing aluminum plates 10 are in contact with the outer surface of the S-shaped conveying aluminum pipe 5. Through the heat-absorbing aluminum plates 10, the heat transmitted by the S-shaped conveying aluminum pipe 5 can be quickly absorbed. Due to the excellent thermal conductivity of aluminum, the absorbed heat can be quickly transferred to the surrounding air. The setting of multiple heat-absorbing aluminum plates 10 increases the total heat absorption and heat dissipation area, effectively assists the S-shaped conveying aluminum pipe 5 in heat dissipation, enhances the heat dissipation capacity of the entire heating device, and enables the greenhouse to obtain heat faster and more evenly, meeting the needs of crops for a warm environment.

[0026] The implementation principle of a heating device for greenhouse cultivation according to this application is as follows: external hot water flows into the S-shaped conveying aluminum pipe 5 through a high-pressure conveying pump and hot water supply pipe 6. The S-shaped conveying aluminum pipe 5 increases the contact area with the surrounding air. In addition, due to the good thermal conductivity of aluminum, the heat of the hot water can be quickly transferred to the S-shaped conveying aluminum pipe 5. The heat-absorbing aluminum plate 10 below the S-shaped conveying aluminum pipe 5, which is in close contact with it, quickly absorbs the heat and dissipates the heat into the surrounding air due to the excellent thermal conductivity of aluminum.

[0027] At this time, the exhaust fan 4 starts, and the hot air is discharged through the L-shaped exhaust pipe 8 under its action. At the same time, the triangular guide plate 12 on the bottom surface of the rectangular mounting housing 2 changes the air flow path, prevents local air stagnation, and promotes the full distribution of the heat emitted by the S-shaped conveying aluminum pipe 5 in the housing. Then, it is discharged through the L-shaped exhaust pipe 8 and the exhaust hole 9, allowing the hot air to disperse into the greenhouse and promote uniform heating of the air. The circulation pipe 7 will transport the used hot water in the S-shaped conveying aluminum pipe 5 back to the heating equipment, achieving the recycling of water resources and heat. Through the coordinated arrangement of the S-shaped conveying aluminum pipe 5, the heat-absorbing aluminum plate 10, the L-shaped exhaust pipe 8 and the exhaust hole 9, this device can efficiently exchange heat between hot water and air, so that the hot air is evenly dispersed into the greenhouse, making the temperature inside the greenhouse more uniform and significantly improving the heating efficiency.
