Description
Technical Field
[0001] This utility model relates to the field of solar greenhouse technology, specifically a frost-resistant solar greenhouse heating device. Background Technology
[0002] my country has a vast territory with diverse and complex geographical and climatic conditions. The use of solar greenhouses for the cultivation of vegetables, flowers, and other crops plays a crucial role in effectively alleviating seasonal shortages of vegetables, generating significant social and economic benefits. The core advantage of solar greenhouses lies in their ability to fully capture and utilize solar energy to achieve significant internal warming. With increasingly sophisticated supporting technologies, this model has successfully supported year-round production of some horticultural crops in northern my country, demonstrating its important position in facility agriculture.
[0003] However, traditional greenhouse structures generally suffer from insufficient insulation, and their internal thermal environment is highly dependent on light conditions. During prolonged cloudy days or periods of insufficient sunlight, the greenhouse's heating effect drops sharply or even stops, making it difficult to maintain the suitable temperature for crop growth and greatly increasing the risk of frost damage. Furthermore, in harsh winters, traditional methods often employ simple and inefficient heating techniques to combat low temperatures. This singular pursuit of temperature increases can easily lead to a sharp drop in relative humidity inside the greenhouse, creating an excessively dry environment that is detrimental to healthy crop growth.
[0004] Based on this, a frost-resistant solar greenhouse heating device is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

Detailed Implementation
[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.
[0027] In one embodiment, such as Figures 1-8 As shown, a frost-resistant greenhouse heating device includes a greenhouse body 11 and pipe bodies 12. A plurality of pipe bodies 12 are arranged in an equally spaced array inside the greenhouse body 11. Each pipe body 12 has a fixed partition 13 inside, which divides the interior of the pipe body 12 into an air inlet channel and a liquid inlet channel. One end of each air inlet channel and liquid inlet channel is connected to a first connecting pipe and a second connecting pipe, respectively. The first connecting pipe is connected to a gas delivery pipe 16, and the second connecting pipe is connected to a liquid delivery pipe 19. The bottom end of each pipe body 12 is connected to a pipe at a position corresponding to the air inlet channel and the liquid inlet channel. The greenhouse has several jet nozzles 14 and atomizing nozzles 15. The gas delivery pipe 16 and the liquid delivery pipe 19 are both fixedly installed on the greenhouse body 11. One end of the gas delivery pipe 16 is equipped with a heating mechanism for increasing the internal temperature of the greenhouse body 11, and one end of the liquid delivery pipe 19 is equipped with a humidifying mechanism for increasing the internal humidity of the greenhouse body 11. The bottom of the greenhouse body 11 is equipped with several exhaust pipes 28. The heating mechanism facilitates the delivery of hot air into the air inlet channel, thereby regulating the internal temperature of the greenhouse body 11. The humidifying mechanism facilitates the delivery of liquid into the liquid inlet channel, thereby regulating the internal humidity of the greenhouse body 11.
[0028] The heating mechanism includes an air pump 18, which is fixedly mounted on the upper end of a first fixed plate. The first fixed plate is fixedly mounted on the greenhouse body 11. The output end of the air pump 18 is connected to the input end of a heating box 17. The heating box 17 is fixedly mounted on the upper end of the first fixed plate. The output end of the heating box 17 is connected to a first conveying pipe. The other end of the first conveying pipe is connected to one end of a gas conveying pipe 16. In use, when it is necessary to heat the inside of the greenhouse body 11, the heating box 17 and the air pump 18 are started. The air pump 18 delivers air into the heating box 17. The heating components inside the heating box 17 can heat the air according to the required temperature. Then, the heated air enters the gas conveying pipe 16. The gas conveying pipe 16 delivers the hot air to several air inlet channels. Then, the jet nozzle 14 discharges the air, thereby heating the inside of the greenhouse body 11.
[0029] The humidification mechanism includes a liquid pump 20, which is fixedly mounted on the upper end of a second fixed plate. The second fixed plate is fixedly mounted on one side of the greenhouse body 11. The input end of the liquid pump 20 is connected to the inside of the liquid storage tank 21, and the output end of the liquid pump 20 is connected to a second delivery pipe. The second delivery pipe is connected to one end of a liquid delivery pipe 19. The heating box 17, the air pump 18, and the liquid pump 20 are all electrically connected to a control component 33, which is fixedly mounted on the upper end of the second fixed plate. In use, when it is necessary to humidify the inside of the greenhouse body 11, the control component 33 controls the liquid pump 20 to start. The liquid pump 20 draws liquid from the inside of the liquid storage tank 21 and delivers the liquid to the inside of the liquid delivery pipe 19 through the second delivery pipe. The liquid delivery pipe 19 delivers the liquid to the liquid inlet channel and then sprays it out through the atomizing nozzle 15, thereby increasing the humidity inside the greenhouse body 11.
[0030] The storage tank 21 has a rotating mounting shaft 22 inside. A rotating tube 23 is coaxially mounted on the outside of the mounting shaft 22. One end of the rotating tube 23 is rotatably connected to the mounting shaft 22. A spiral plate 24 is fixedly mounted on the mounting shaft 22, and the spiral plate 24 is tightly fitted inside the rotating tube 23. Several stirring rods are provided on the outside of the rotating tube 23. A sleeve is fixedly mounted on the upper end of the rotating tube 23. A first bevel gear is fixedly mounted on one end of the sleeve. A second bevel gear is fixedly mounted on one end of the mounting shaft 22. Both the first and second bevel gears mesh with a third bevel gear. The third bevel gear is fixedly mounted on the output end of a motor 26. The motor 26 is fixedly mounted on the upper end of the storage tank 21 and is electrically connected to a control component 33. Several heaters 2 are fixedly mounted on the bottom end of the storage tank 21. 5. In use, when humidification is required inside the greenhouse body 11, the control component 33 controls the heater 25 to start. The heater 25 heats the liquid inside the storage tank 21, thereby preventing the temperature inside the greenhouse body 11 from dropping during humidification. When it is necessary to spray pesticides inside the greenhouse body 11, the pesticides and water are added to the storage tank 21, and the motor 26 is started at the same time. The output end of the motor 26 drives the third bevel gear to rotate. The third bevel gear meshes with the first bevel gear and the second bevel gear, causing the mounting shaft 22 and the rotating tube 23 to rotate in opposite directions. The mounting shaft 22 drives the spiral plate 24 to rotate. The spiral plate 24 cooperates with the rotating tube 23 to transport the liquid inside the storage tank 21, so that the liquid inside the storage tank 21 circulates, thereby preventing the pesticide solution inside the storage tank 21 from separating.
[0031] Each exhaust pipe 28 has a sliding sealing plug 29 inside. Each sealing plug 29 has a fixed rod at its upper end. Each fixed rod has a second electromagnet 31 at one end. Each exhaust pipe 28 has a first electromagnet 30 at the position corresponding to the second electromagnet 31. Both the first electromagnet 30 and the second electromagnet 31 are electrically connected to the control component 33. In use, when the greenhouse body 11 needs to be cooled, the control component 33 controls the first electromagnet 30 and the second electromagnet 31 so that the magnetic poles of the contact surfaces of the first electromagnet 30 and the second electromagnet 31 are the same. Under the action of magnetic force, the sealing plug 29 rises, allowing air to circulate between the inside and outside of the greenhouse body 11, thereby reducing the temperature inside the greenhouse body 11. After adjustment, the magnetic poles of the contact surfaces of the first electromagnet 30 and the second electromagnet 31 are opposite, causing the first electromagnet 30 and the second electromagnet 31 to attract each other, thus sealing the sealing plug 29 and one end of the exhaust pipe 28.
[0032] Each exhaust pipe 28 is connected to a ventilation pipe 27 at one end. The ventilation pipe 27 is fixedly installed on the greenhouse body 11. The diameter of the cross-section at both ends of the ventilation pipe 27 is several times larger than the diameter of the middle cross-section. When it is necessary to reduce the internal temperature of the greenhouse body 11, the external air flows through the ventilation pipe 27. According to the Venturi effect, when the confined flow passes through the narrowed flow cross-section, the fluid velocity increases. Low pressure is generated near the high-speed fluid, which produces an adsorption effect, thereby accelerating the exhaust of air from the greenhouse body 11.
[0033] Each exhaust pipe 28 is equipped with a temperature and humidity sensor 32, which is electrically connected to the control component 33. In use, the temperature and humidity sensor 32 facilitates the detection of the internal temperature and humidity of the greenhouse body 11, thereby facilitating the control component 33 to control the heating temperature of the liquid pump 20 and the heating box 17. It is worth noting that the heating box 17, temperature and humidity sensor 32 and control component 33 in this application are all existing components, and the connection and control methods are all known, so they will not be described in detail here.
[0034] The above embodiment discloses a frost-resistant greenhouse heating device. When heating is required inside the greenhouse body 11, the heating box 17 and air pump 18 are activated. The air pump 18 supplies air into the heating box 17. The heating components inside the heating box 17 heat the air according to the required temperature. The heated air then enters the gas delivery pipe 16, which delivers the hot air to several air inlet channels. The air jet 14 then discharges the air, thus heating the inside of the greenhouse body 11. When humidification is required inside the greenhouse body 11, the control component 33 controls the liquid pump 20 to start. The liquid pump 20 draws liquid from the storage tank 21 and delivers the liquid to the liquid delivery system through the second delivery pipe. Inside pipe 19, liquid delivery pipe 19 delivers liquid to the liquid inlet channel, and then sprays it out through atomizing nozzle 15, thereby increasing the humidity inside the greenhouse body 11. When the greenhouse body 11 needs to be cooled, control component 33 controls first electromagnet 30 and second electromagnet 31 so that the magnetic poles of the contact surfaces of first electromagnet 30 and second electromagnet 31 are the same. Under the action of magnetic force, sealing plug 29 rises, allowing air to circulate between the inside and outside of the greenhouse body 11, thereby reducing the temperature inside the greenhouse body 11. After adjustment, the magnetic poles of the contact surfaces of first electromagnet 30 and second electromagnet 31 are opposite, causing first electromagnet 30 and second electromagnet 31 to attract each other, thus sealing plug 29 and one end of exhaust pipe 28.
[0035] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
