Description

Technical Field

[0001] This utility model relates to the field of greenhouse environment temperature control technology, and in particular to a device for regulating the temperature of an agricultural greenhouse environment. Background Technology

[0002] During the high-temperature period in summer, solar radiation is strong, and the temperature outside the greenhouse rises sharply. A large amount of heat is conducted and radiated into the greenhouse through the greenhouse structure, causing the indoor temperature to rise rapidly. Existing greenhouses often lack effective cooling methods to deal with high temperatures, mainly relying on natural ventilation or fans for cooling, which has a poor cooling effect and can easily affect crop yield and quality.

[0003] Therefore, it is necessary to design a device that can cool down the greenhouse environment by shading, ventilation, and spraying water mist when the temperature inside the greenhouse is too high, maintain a suitable growth temperature, and improve crop yield and quality. Utility Model Content

[0004] To overcome the shortcomings of existing greenhouses that rely mainly on natural ventilation or fans for cooling when dealing with high temperatures, resulting in poor cooling effects and potential impacts on crop yield and quality, this invention provides a device for regulating the environmental temperature of agricultural greenhouses. This device can cool the greenhouse by using shading, ventilation, and water mist spraying when the internal temperature is too high, maintaining a suitable growth temperature and improving crop yield and quality.

[0005] The technical solution is as follows: A device for regulating the ambient temperature of an agricultural greenhouse includes a greenhouse, a fan, a reflective film, a temperature sensor, planting boxes, a shading component, and a water spraying component. Fans are installed at both the front and rear of the greenhouse. A reflective film is connected to the inner side of the upper part of the greenhouse. Two temperature sensors are connected to the inner sides of both the front and rear of the greenhouse. Multiple planting boxes are placed at the bottom inside the greenhouse. A shading component is provided at the top of the greenhouse to provide shade when the temperature inside the greenhouse is too high. A water spraying component is provided at the top of the greenhouse to spray water and cool down when the temperature inside the greenhouse is too high.

[0006] As an improvement to the above solution, the shading assembly includes a shading cloth, a first motor, a connecting rod, a cylinder, a spring, and a first lead screw. The cylinder is connected to the upper right part of the greenhouse, and a rotating shaft is provided inside the cylinder. The shading cloth is wound around the rotating shaft. The first motor is connected to the upper left part of the greenhouse. The first motor is electrically connected to a temperature sensor. The first lead screw is connected to the output shaft of the first motor. The first lead screw is rotatably connected to the greenhouse. A connecting rod is threaded onto the first lead screw. The connecting rod is slidably connected to the greenhouse. A spring connects the shading cloth and the rotating shaft.

[0007] As an improvement to the above solution, it also includes a support plate and a heating lamp. The lower sides of both the left and right sides of the reflective film are connected to the support plate, and the lower side of the support plate is connected to the heating lamp.

[0008] As an improvement to the above scheme, it also includes a filter screen, with two sets of filter screens connected to the inner side of the middle of the greenhouse, each set consisting of multiple filter screens.

[0009] As an improvement to the above scheme, a humidity sensor is also included. Two sets of humidity sensors are connected to the inner side of the lower part of the greenhouse, each set consisting of multiple humidity sensors.

[0010] As an improvement to the above solution, a water spraying assembly is also included. The water spraying assembly includes a water pipe, atomizing nozzles, a connecting block, a second lead screw, and a second motor. The water pipe is slidably connected to the upper right part of the greenhouse, and four atomizing nozzles are connected to the lower side of the water pipe. A connecting block is connected to the rear side of the water pipe. The second motor is connected to the upper left part of the greenhouse. The second motor is electrically connected to the temperature sensor and the humidity sensor. A second lead screw is connected to the output shaft of the second motor. The second lead screw is rotatably connected to the greenhouse. The connecting block is threadedly connected to the second lead screw.

[0011] This utility model has the following advantages: 1. This utility model starts the first motor, drives the first lead screw to rotate, causes the connecting rod to move, and extends the shading. Through the ventilation of the fan, the second motor starts, drives the second lead screw to rotate, and drives the water pipe to move. Water is sprayed out from the atomizing nozzle, which achieves the effect of cooling down the greenhouse when the temperature inside is too hot through shading, ventilation and spraying water mist, maintaining a suitable growth temperature and improving crop yield and quality.

[0012] 2. When the humidity sensor detects insufficient humidity inside the greenhouse, the second motor will start, driving the second lead screw to rotate. This causes the connecting block to move under the action of the thread, which in turn moves the water pipe, allowing water to be sprayed out through the atomizing nozzle. This achieves the effect of regulating indoor humidity when the greenhouse is relatively dry, facilitating plant growth in a suitable environment and making it easier to replenish water.

[0020] A device for regulating the ambient temperature of an agricultural greenhouse, such as Figures 1-3 As shown, the system includes a greenhouse 1, a fan 2, a reflective film 4, a support plate 5, a filter 7, a heater 6, a humidity sensor 8, a temperature sensor 9, planting boxes 10, a shading assembly, and a water spray assembly. Fans 2 are installed at both the front and rear of the greenhouse 1. A reflective film 4 is connected to the inner upper part of the greenhouse 1. Support plates 5 are connected to the lower left and right sides of the reflective film 4. Heaters 6 are connected to the lower side of the support plates 5. Two sets of filters 7, each consisting of three filters, are connected to the inner middle part of the greenhouse 1. Two sets of humidity sensors 8, each consisting of three humidity sensors, are connected to the inner lower part of the greenhouse 1. Two temperature sensors 9 are connected to the inner front and rear of the greenhouse 1. Nine planting boxes 10 are placed at the bottom inside the greenhouse 1. A shading assembly and a water spray assembly are installed at the top of the greenhouse 1.

[0021] like Figure 1 , Figure 2 and Figure 5 As shown, the shading assembly includes a shading cloth 3, a first motor 31, a connecting rod 32, a cylinder 33, a spring 34, and a first lead screw 35. The cylinder 33 is connected to the upper right of the greenhouse 1. The cylinder 33 has a rotating shaft inside, and the shading cloth 3 is wound around the rotating shaft. The first motor 31 is connected to the upper left of the greenhouse 1. The first motor 31 is electrically connected to the temperature sensor 9. The first lead screw 35 is connected to the output shaft of the first motor 31. The first lead screw 35 is rotatably connected to the greenhouse 1. The connecting rod 32 is threadedly connected to the first lead screw 35. The connecting rod 32 is slidably connected to the greenhouse 1. The spring 34 is connected between the shading cloth 3 and the rotating shaft.

[0022] like Figures 2-4As shown, it also includes a water spraying assembly, which includes a water pipe 11, atomizing nozzles 12, a connecting block 13, a second lead screw 14, and a second motor 15. The water pipe 11 is slidably connected to the upper right of the greenhouse 1, and four atomizing nozzles 12 are connected to the lower side of the water pipe 11. The connecting block 13 is connected to the rear side of the water pipe 11. The second motor 15 is connected to the upper left of the greenhouse 1. The second motor 15 is electrically connected to the temperature sensor 9 and the humidity sensor 8. The second lead screw 14 is connected to the output shaft of the second motor 15. The second lead screw 14 is rotatably connected to the greenhouse 1, and the connecting block 13 is threadedly connected to the second lead screw 14.

[0023] When using this equipment, first install greenhouse 1 in the plant cultivation area, then plant the plants in planting boxes 10. Sunlight is refracted through reflective film 4, allowing sunlight to reach the plants and provide light. Water is then delivered through external pipes connected to water pipe 11. During plant growth, temperature sensor 9 detects the temperature of greenhouse 1, and humidity sensor 8 detects the humidity. When the temperature is too high, the first motor 31 starts, driving the first lead screw 35 to rotate, causing the connecting rod 32 to move to the left under the action of the thread. This releases the shade cloth 3 from the cylinder 33, causing the shaft inside the cylinder 33 to rotate, deforming the spring 34. The shade cloth 3 then provides shading. Simultaneously, fan 2 is activated for ventilation, and dust is blocked by filter screen 7. At the same time, the second motor 15 starts, driving the second lead screw 14 to rotate, causing the connecting block 13 to move under the action of the thread. This moves water pipe 11, allowing water to enter the water pipe 11 and then be atomized and sprayed out from the atomizing nozzle 12. The water is absorbed during evaporation. The abundant heat helps to lower the temperature of greenhouse 1, allowing for cooling through shading, ventilation, and water mist spraying when the temperature inside greenhouse 1 becomes too high. This maintains a suitable growth temperature, improving crop yield and quality. When the temperature sensor 9 detects a normal temperature, the first motor 31 drives the lead screw to rotate in the opposite direction, causing the connecting rod 32 to move to the right under the action of the thread. The spring 34 gradually returns to its original position, driving the rotating shaft to rotate, causing the shading cloth 3 to roll onto the rotating shaft. At the same time, the second motor 15 is turned off. When the humidity sensor 8 detects insufficient humidity inside greenhouse 1, the second motor 15 will also start, driving the second lead screw 14 to rotate, causing the connecting block 13 to move under the action of the thread. This moves the water pipe 11, allowing water to be sprayed out through the atomizing nozzle 12. This allows for the regulation of indoor humidity when the inside of greenhouse 1 is relatively dry, facilitating plant growth in a suitable environment and making it easier to replenish water. When the temperature inside greenhouse 1 is low, the heating lamp 6 can be turned on to provide a certain temperature.
