Description

Technical Field

[0001] This utility model relates to an agricultural temperature control system, and more particularly to an intelligent temperature control system for facility agriculture. Background Technology

[0002] A greenhouse, also known as a hothouse, is a facility that allows light to pass through and provides heat or warmth for cultivating plants. In seasons when plants are not suitable for growth, it can provide a growing season and increase yields. It is often used for the cultivation or seedling raising of warm-loving vegetables, flowers, trees, and other plants during cold seasons. A large shed is also a type of greenhouse. Existing methods for regulating greenhouse temperature mostly rely on ventilation holes for heat dissipation, using a sealed greenhouse structure to raise the internal temperature. However, this method is difficult to precisely regulate the greenhouse temperature, and in hot weather, opening the greenhouse structure does not effectively lower the temperature. Furthermore, direct sunlight through the greenhouse roof over a large area further increases the temperature, and prolonged exposure to strong sunlight can easily cause plants to wither and die. Existing temperature control devices that can block sunlight, such as the intelligent greenhouse temperature control device described in application number CN202420105199.3, use a single piece of shading cloth to achieve a shading effect. This cannot ensure uniform light distribution within the greenhouse while simultaneously cooling and shading. Additionally, using spray systems for cooling can affect humidity levels, which is unfavorable for crops with humidity requirements. Utility Model Content

[0023] Example 1:

[0024] like Figure 1-7As shown, the present invention provides an intelligent temperature control system for facility agriculture, comprising: a temperature control mechanism, a ventilation mechanism, a control and acquisition mechanism, and multiple shading mechanisms; each shading mechanism includes an installation frame, a shading cloth 26, a winding branch, and a light transmission adjustment branch; a controller, a wireless communication module, and a memory are installed on the control and acquisition mechanism; the wireless communication module and the memory are electrically connected to the controller; the control and acquisition mechanism is used to collect data such as temperature and humidity inside the greenhouse; the temperature control mechanism is used to control the temperature inside the greenhouse; the ventilation mechanism is used to ventilate the greenhouse; the installation frame is installed at the bottom of the greenhouse; the winding branch is installed on the installation frame for winding and unwinding the shading cloth 26, which is used to block the area within the installation frame; the light transmission adjustment branch is installed on the shading cloth 26 for adjusting the shading area of ​​the shading cloth 26; a button panel 4 electrically connected to the controller is installed on the control and acquisition mechanism; the temperature control mechanism, the ventilation mechanism, the control and acquisition mechanism, and the winding branch are all driven and controlled by the controller.

[0025] The system collects temperature and humidity data within the greenhouse using a control acquisition mechanism. This allows the controller to monitor these data and automatically control the temperature control and ventilation systems. The controller stores the collected data in its memory and uploads it to a remote control center via a wireless communication module. Simultaneously, the remote control center can send control signals to the controller via the same module. The temperature control mechanism regulates the greenhouse temperature, while the ventilation system blows air through the greenhouse to ensure proper airflow, maintaining suitable temperature and humidity levels and promoting plant growth. A retractable branch allows for the raising and lowering of the shading cloth 26. Workers can determine whether the shading cloth 26 needs to be lowered based on external light conditions and control its raising and lowering via the button panel 4 and the controller. This eliminates the need for workers to climb to the top of the greenhouse to retract the cloth, improving ease of adjustment. If the shading cloth 26 is released, the light-transmitting branch adjusts its shading area as needed, ensuring more uniform lighting within the greenhouse. This system works in conjunction with the temperature control mechanism to effectively adjust the greenhouse temperature and improve its efficiency.

[0026] Furthermore, the control and acquisition mechanism includes an acquisition column 7 and a control box 1; the control box 1 is installed on the upper end of the acquisition column 7, and a positioning plate 8 is fixed on the lower end of the acquisition column 7; multiple positioning pins 9 are fixed on the lower side of the positioning plate 8; a temperature sensor and a humidity sensor 5 electrically connected to the controller are provided on the bottom surface of the control box 1; a light-shielding awning 6 is fixed on the lower edge of the control box 1; a display screen 3 electrically connected to the controller is installed on the control box 1; and a button panel 4 is located on the control box 1.

[0028] Furthermore, the temperature control mechanism includes a control housing 10, a hot air blower, a cold air blower, and multiple air outlet ducts; the air outlet ducts include an air outlet flexible hose 11, an extension pipe 12, and an air outlet long pipe 13;

[0029] Both the hot air blower and the cold air blower are installed inside the control housing 10; an air inlet window is provided on the top surface of the control housing 10; the air inlets of the hot air blower and the cold air blower are connected to the air inlet window of the control housing 10; one end of the outlet hose 11 of each outlet pipe is fixed to the control housing 10, and the other end is connected to one end of each extension pipe 12, and the other end of each extension pipe 12 is connected to each outlet long pipe 13; an air outlet is provided on the lower side of each outlet long pipe 13; a filter screen 14 is provided on the air inlet window of the control housing 10 and the air outlet of each outlet long pipe 13; a second switch circuit connected to the controller is connected in series on the power supply line of the hot air blower; a first switch circuit connected to the controller is connected in series on the power supply line of the cold air blower; a support rod 15 is fixed on the lower end of the extension pipe 12, and the lower end of the support rod 15 is set as a pointed end; a support plate 16 is provided on the lower side of the support rod 15.

[0030] The system utilizes both air coolers and hot air blowers to facilitate temperature control within the greenhouse. A preset temperature threshold range is established. When the temperature sensor detects that the greenhouse temperature exceeds the threshold range, the controller activates the air cooler via a first switching circuit until the greenhouse temperature reaches the midpoint of the threshold range. Conversely, when the temperature sensor detects that the greenhouse temperature falls below the threshold range, the controller activates the hot air blower via a second switching circuit until the greenhouse temperature reaches the midpoint of the threshold range, thus regulating the greenhouse temperature. Furthermore, the number and installation location of each air outlet duct can be customized to deliver cold or hot air throughout the greenhouse, improving the uniformity of temperature changes.

[0031] Furthermore, the ventilation mechanism includes a ventilation fan 17 and four limiting slots 18; the bottom surfaces of the four limiting slots 18 are all fixed to the ventilation fan 17; ventilation windows are provided on the side wall of the greenhouse; the four limiting slots 18 are respectively used to snap onto the four edges of the ventilation windows; a third switch circuit that is electrically connected to the controller is connected in series on the power supply line of the ventilation fan 17.

[0032] The ventilation fan 17 is used to blow air into the greenhouse. A humidity threshold is preset. When the humidity detected by the humidity sensor 5 is higher than the humidity threshold, the controller controls the ventilation fan 17 to operate and dehumidify the air in the greenhouse.

[0033] Furthermore, the mounting frame includes a base rod 23, a winding square tube 19, and two swing rods 20; the lower ends of the two swing rods 20 are rotatably mounted on both ends of the base rod 23, and the upper ends are rotatably mounted on both ends of the winding square tube 19; the winding branch is mounted on the winding square tube 19 for winding the light-shielding cloth 26 inside the winding square tube 19; guide grooves 21 are provided on the opposite sides of the two swing rods 20; a guide rod 31 is fixed on the lower edge of the light-shielding cloth 26; guide wheels are rotatably mounted on both ends of the guide rod 31; the two guide wheels are respectively engaged and travel on the two guide grooves 21; a counterweight 32 is fixed on the guide rod 31.

[0034] The counterweight 32 acts as a counterweight when releasing the shading cloth 26, ensuring that the shading cloth 26 can be released smoothly; the guide wheel reduces friction and improves the movement stability of the guide rod 31, reducing the possibility of jamming. At the same time, the guide groove 21 restricts the position of the guide wheel to prevent the shading cloth 26 from being blown up by the wind; the swing rod 20's swing installation method makes it easy to install on the top of the greenhouse and can adapt to different inclination angles of different greenhouse tops.

[0035] Furthermore, the take-up branch includes a take-up shaft 25 and a take-up / undo drive motor 24; the take-up shaft 25 is rotatably mounted inside the take-up square tube 19; the take-up / undo drive motor 24 drives the take-up shaft 25 to rotate through the take-up chain transmission pair, and is electrically connected to the controller through the take-up / undo drive circuit; the upper edge of the light-shielding cloth 26 is fixed on the take-up shaft 25; and an elongated hole 22 for the light-shielding cloth 26 to pass through is provided on the take-up square tube 19.

[0036] The chain drive pair is driven by the take-up drive motor 24 under the control of the controller, so that the take-up shaft 25 rotates to take up and take down the blackout cloth 26.

[0037] Furthermore, the light-transmitting adjustment branch includes a positioning rod 33 and multiple light-transmitting units; each light-transmitting unit includes a shielding cloth 37, a counterweight rod 38, and two adjusting ropes 29; multiple light-transmitting openings 27 are spaced apart on the light-blocking cloth 26; the upper edge of the shielding cloth 37 of each light-transmitting unit is fixed to the upper edge of each light-transmitting opening 27 to completely cover the corresponding light-transmitting opening 27; a counterweight rod 38 is fixed to the lower edge of the shielding cloth 37; two adjusting holes 30 are provided on the light-blocking cloth 26 above each light-transmitting opening 27; a metal ring is installed on each adjusting hole 30; one end of each of the two adjusting ropes 29 is fixed to the counterweight rod 38, and the other end is fixed to the positioning rod 33, with the middle part passing through the two metal rings above the light-transmitting opening 27 respectively; two parallel rods 34 are fixed on the bottom rod 23; multiple positioning posts 35 are correspondingly provided on the two parallel rods 34; the positioning rod 33 is used to press on the positioning posts 35 at two corresponding positions.

[0038] The light transmittance of the blackout cloth 26 can be adjusted by utilizing the cooperation between the blackout cloth 37, the counterweight rod 38, the adjusting rope 29, and the positioning rod 33. After the blackout cloth 37 is released by the winding branch, the positioning rod 33 is pulled as needed, and the positioning rod is pressed against the positioning posts at two corresponding positions. The two adjusting ropes 29 drive the counterweight rod 38 to move upward, which in turn moves the blackout cloth 37 upward, thereby adjusting the light transmittance area of ​​the light-transmitting opening 27. This allows for a relatively uniform adjustment of the blackout area of ​​the blackout cloth 37, ensuring relatively uniform illuminance while providing shading and cooling. A metal ring is used to prevent the adjusting rope 29 from pulling back and forth and damaging the blackout cloth 37.
