Description

Technical Field

[0001] The utility model relates to the technical field of greenhouse greenhouses, in particular to a temperature adjustment device for greenhouses. Background Technique

[0002] Traditional greenhouse cooling methods mainly rely on the basic and traditional means of ventilation cooling. As a common method for cooling, ventilation uses the natural ventilation method to utilize the air convection generated by the temperature difference between the inside and outside of the greenhouse to discharge the excess heat and moisture in the greenhouse, thereby achieving the cooling effect. On the other hand, the temperature increase in the greenhouse generally adopts the method of burning fuel for heating. This method burns fuels such as coal, firewood, and natural gas to release heat energy and heat the air or soil in the greenhouse to increase the temperature inside the greenhouse.

[0003] However, natural ventilation for greenhouse cooling highly depends on external weather conditions and temperature conditions. In hot summers or when the external temperature is high, the cooling effect of natural ventilation will be greatly reduced, making it difficult to meet the requirements of the crops in the greenhouse for suitable temperatures. Burning fuel for heating the greenhouse has high fuel costs. Especially for large-scale farmers, the long-term fuel consumption is a significant economic burden. Secondly, burning fuel will produce a large amount of harmful gases such as soot and carbon dioxide, which have an adverse impact on the environment and air quality. Therefore, we propose a new type of greenhouse temperature adjustment device. Content of the Utility Model

[0015] (III) Beneficial effects

[0016] Compared with the prior art, the present utility model provides one, having the following beneficial effects:

[0017] 1. By setting a heating mechanism including a hot air blower and a first humidifier, the present utility model realizes the dual functions of heating and humidifying. The hot air blower quickly generates hot air, while the first humidifier converts water into water vapor and mixes it into the hot air to increase the air humidity. The hot air on-off valve and the first moisture on-off valve, as key control elements, ensure the precise control of the heating and humidifying processes, significantly reducing the environmental pollution and economic burden brought by the traditional fuel-burning heating method, and providing a more environmentally friendly and economical solution for the sustainable development of modern agriculture.

[0018] 2. The utility model realizes the two-way regulation of the temperature in the greenhouse by introducing a cooling mechanism, including a cold air blower and a second humidifier. The cold air blower quickly generates cold air, while the second humidifier can adjust the air humidity according to the demand during the cooling process to avoid damage to crops due to too low humidity. The precise control of the cold air on-off valve and the second moisture on-off valve ensures the efficient mixing of cold air and humidified cold air to form a suitable cold and humid air flow. This efficient cooling and humidity regulation system provides an ideal growth environment for crops in summer or high-temperature weather, effectively overcoming the drawback of unstable natural ventilation cooling effect.

[0019] 3. The utility model realizes the uniform distribution of the air flow after heating or cooling by designing a gas guiding mechanism, including a third three-way pipe, a main flow pipe, a shunt pipe and a nozzle. The third three-way pipe, as the key node for air flow convergence, merges the air flows from the heating mechanism and the cooling mechanism and sends them into the main flow pipe. The main flow pipe is laid along the top of the greenhouse to ensure the stability of the long-distance transmission of the air flow. The evenly distributed shunt pipes and multiple nozzles on them further refine the distribution of the air flow, enabling each crop area to obtain sufficient and uniform air flow coverage. This design not only improves the uniformity of the air flow distribution but also enhances the temperature regulation effect, providing a strong guarantee for the healthy growth of crops.

[0032] Please refer to Figures 1 to 5 , the present utility model provides a technical solution:

[0033] Embodiment 1

[0034] As Figures 1 to 5 , the present utility model provides a greenhouse temperature control device, including a greenhouse body 1, characterized in that: a heating mechanism 2 is arranged on the outer side of the greenhouse body 1, a cooling mechanism 3 is arranged on the right side of the heating mechanism 2, an air guiding mechanism 4 is arranged on the top of the inner cavity of the greenhouse body 1, a detection mechanism 5 is arranged on the inner wall of the greenhouse body 1, the heating mechanism 2 includes a hot air blower 21, a first humidifier 22 is arranged on the left side of the hot air blower 21, the output end of the hot air blower 21 is fixedly installed with a hot air on-off valve 23, the output end of the first humidifier 22 is fixedly installed with a first moisture on-off valve 24, the top end of the first moisture on-off valve 24 is fixedly installed with a first three-way pipe 25, the left port at the lower end of the first three-way pipe 25 is fixedly connected to the upper end of the first moisture on-off valve 24, the right port at the lower end of the first three-way pipe 25 is fixedly connected to the upper end of the hot air on-off valve 23, and the upper port of the first three-way pipe 25 is fixedly connected to the left port at the lower end of the third three-way pipe 41.

[0035] In this embodiment, through the heating mechanism 2 in the greenhouse temperature control device, this mechanism not only includes the hot air blower 21 as a heat source, but also ingeniously integrates the first humidifier 22 to realize the dual functions of heating and humidifying. The hot air blower 21 quickly generates hot air by efficiently converting electrical energy into heat energy, while the first humidifier 22 converts water into water vapor through ultrasonic vibration or evaporation technology and mixes it into the hot air to increase the air humidity. The hot air on-off valve 23 and the first moisture on-off valve 24, as key control components, respectively regulate the flow rates of hot air and moisture to ensure precise control of the heating and humidifying processes. The two converge in the first three-way pipe 25 to form a warm and humid air flow, which is further transmitted to the inside of the greenhouse through the third three-way pipe 41, realizing the intelligent heating and humidifying adjustment of the greenhouse environment.

[0036] This design not only improves the heating efficiency, but also significantly reduces the environmental pollution and economic burden brought by the traditional fuel-burning heating method, providing a more environmentally friendly and economical solution for the sustainable development of modern agriculture.

[0037] Embodiment 2

[0038] As Figures 1 to 5 shown, on the basis of Embodiment 1, the present utility model provides a technical solution: Preferably, the cooling mechanism 3 includes a cold air blower 31 fixedly installed outside the greenhouse body 1. A second humidifier 32 is arranged on the right side of the cold air blower 31. The output end of the cold air blower 31 is fixedly installed with a cold air on-off valve 33. The output end of the second humidifier 32 is fixedly installed with a second moisture on-off valve 34. The top end of the second moisture on-off valve 34 is fixedly installed with a second three-way pipe 35. The left port at the lower end of the second three-way pipe 35 is fixedly connected to the upper end of the cold air on-off valve 33. The right port at the lower end of the second three-way pipe 35 is fixedly connected to the upper end of the second moisture on-off valve 34. The upper port of the second three-way pipe 35 is fixedly connected to the right port at the lower end of the third three-way pipe 41.

[0039] In this embodiment, by introducing the cooling mechanism 3, two-way adjustment of the temperature inside the greenhouse is achieved. The cold air blower 31, as the core equipment for cooling, quickly generates cold air through the circulation of refrigerant or compression refrigeration technology. At the same time, the addition of the second humidifier 32 enables the adjustment of air humidity according to requirements during the cooling process, avoiding damage to crops due to too low humidity. The precise control of the cold air on-off valve 33 and the second moisture on-off valve 34 ensures the efficient mixing of cold air and humidified cold air in the second three-way pipe 35 to form a suitable cold and humid air flow. Subsequently, this cold and humid air flow enters the main flow pipe 42 through the third three-way pipe 41 and is evenly sprayed into the greenhouse through the shunt pipe 43 and the nozzles 45 thereon, achieving rapid and effective cooling and humidity adjustment, and providing an ideal growth environment for crops in summer or high-temperature weather.

[0040] Embodiment 3

[0041] As Figures 1 to 5 shown, on the basis of Embodiment 1, the present utility model provides a technical solution: Preferably, the air guiding mechanism 4 includes a third three-way pipe 41 fixedly installed at the upper end of the second three-way pipe 35. The upper port of the third three-way pipe 41 is fixedly installed with a main flow pipe 42. The outside of the main flow pipe 42 is fixedly installed with a shunt pipe 43. A shunt pipe mounting bracket 44 is arranged on the outside of the shunt pipe 43. The shunt pipe mounting bracket 44 is fixedly installed at the top of the inner cavity of the greenhouse body 1. The bottom of the shunt pipe 43 is fixedly installed with nozzles 45, and the number of nozzles 45 is several.

[0042] In this embodiment, through the design and optimization of the air guiding mechanism 4, this mechanism is responsible for evenly distributing the heated or cooled air flow inside the greenhouse. The third three-way pipe 41, as a key node for air flow convergence, combines the air flows from the heating mechanism 2 and the cooling mechanism 3 and then sends them into the main flow pipe 42. The main flow pipe 42 is laid along the top of the greenhouse, ensuring the stability of the long-distance transmission of the air flow. The evenly distributed shunt pipes 43 and the multiple nozzles 45 thereon further refine the distribution of the air flow, enabling each crop area to obtain sufficient and uniform air flow coverage. This design not only improves the uniformity of the air flow distribution but also enhances the temperature regulation effect, providing a strong guarantee for the healthy growth of crops.

[0043] Embodiment 4

[0044] As Figures 1 to 5 shown, on the basis of Embodiment 1, the present utility model provides a technical solution: Preferably, the detection mechanism 5 includes a temperature sensor 51 fixedly installed on the inner wall of the greenhouse body 1, and a humidity sensor 52 is arranged on the left side of the temperature sensor 51. Both the temperature sensor 51 and the humidity sensor 52 are fixedly installed on the inner wall of the greenhouse body 1.

[0045] In this embodiment, the temperature sensor 51 and the humidity sensor 52, as the core components of intelligent detection, are fixedly installed at multiple positions on the inner wall of the greenhouse to ensure comprehensive monitoring of the environmental parameters inside the greenhouse. These high-precision sensors can collect temperature and humidity data in real time and transmit them to an external controller wirelessly or wiredly. The external controller automatically judges the current environmental state according to the preset thresholds or the optimal environmental parameters for crop growth and issues corresponding control instructions, thereby realizing the intelligent adjustment of the greenhouse environment. This intelligent detection and feedback mechanism not only improves the automation level of the temperature regulation equipment but also reduces the frequency and cost of manual intervention, providing strong support for the precise management of modern agriculture.

[0046] During specific use, the working principle of the present utility model is as follows:

[0047] I. Monitoring and feedback mechanism

[0048] The temperature sensor 51 and the humidity sensor 52 installed inside the greenhouse, as the "eyes" of the equipment, continuously monitor the temperature and humidity data inside the greenhouse. After being collected by these high-precision sensors, the data are quickly transmitted to the external controller, providing a scientific basis for subsequent control decisions. The external controller then automatically judges the current environmental state according to the preset thresholds or the optimal environmental parameters for crop growth and issues corresponding control instructions.

[0049] II. Intelligent heating mechanism

[0050] When the temperature sensor 51 detects that the temperature inside the greenhouse is lower than the set value, the external controller responds quickly and starts the working process of the heating mechanism 2. The hot air blower 21, as the main equipment for heating, starts to operate and generate hot air. If the humidity sensor 52 also indicates the need to increase humidity at this time, the first humidifier 22 is started synchronously to mix pure water vapor into the hot air. The hot air and the humidified moisture are precisely controlled by the hot air on-off valve 23 and the first moisture on-off valve 24 respectively to ensure the stability of the flow rate and temperature. After the two converge at the first three-way pipe 25, a warm and humid air flow with appropriate temperature and humidity is formed, enters the main flow pipe 42 through the third three-way pipe 41, and is gently sprayed to each corner of the greenhouse by the evenly distributed flow dividing pipes 43 and the multiple nozzles 45 thereon, achieving a comprehensive and uniform heating and humidifying effect.

[0051] III. Efficient Cooling and Humidity Regulation

[0052] On the contrary, when the temperature sensor 51 monitors that the temperature inside the greenhouse is too high, the external controller activates the working of the cooling mechanism 3. The cooling fan 31 starts quickly to generate a cool air flow. If the humidity needs to be adjusted simultaneously, the second humidifier 32 will also be started to incorporate an appropriate amount of water vapor into the cold air. The cold air and the humidified cold air are controlled by the cold air on-off valve 33 and the second moisture on-off valve 34 respectively to ensure the accuracy of cooling and humidity regulation. After the two are mixed at the second three-way pipe 35, they also enter the main flow pipe 42 through the third three-way pipe 41, and finally are evenly sprayed into the greenhouse by the flow dividing pipes 43 and the nozzle 45 system, achieving rapid and effective cooling and humidity regulation, and creating a cool and humid growth environment for the crops.

[0053] In summary, this greenhouse temperature control equipment, through an integrated heating and cooling system and control mechanism, as well as precise adjustment of environmental parameters, effectively overcomes many drawbacks of traditional temperature control methods, providing strong support for the sustainable development of modern agriculture.

[0054] The above are only specific embodiments of the present utility model, but the technical features of the present utility model are not limited thereto. Any simple changes, equivalent replacements or modifications made based on the present utility model to solve substantially the same technical problems and achieve substantially the same technical effects are all covered by the protection scope of the present utility model.
