Description

Technical Field

[0001] This utility model relates to the field of temperature-controlled greenhouse technology, and in particular to a microgrid-driven multi-zone linkage temperature-controlled greenhouse. Background Technology

[0002] A microgrid-driven multi-zone temperature-controlled greenhouse is a modern agricultural facility that integrates new energy power supply and intelligent environmental control. It can be defined as an integrated agricultural production greenhouse that uses a microgrid system (including distributed power sources, energy storage devices, and energy management modules) as its energy core and achieves precise control of environmental parameters in different areas of the greenhouse through zoned temperature control technology. Specifically, this greenhouse combines renewable energy equipment such as solar photovoltaic panels and small wind turbines with energy storage batteries to form an independent power supply network, providing stable power to the temperature control system, irrigation equipment, and lighting devices. Simultaneously, based on crop type, growth stage, or functional requirements, the greenhouse is divided into multiple independent temperature-controlled zones. Each zone is equipped with temperature sensors, heaters, ventilation fans, and other equipment, and is coordinated and adjusted through a central control system to ensure that the environment in each zone is suitable for crop growth.

[0003] Existing microgrid-driven multi-zone temperature-controlled greenhouses suffer from significant operational inconveniences in the installation and maintenance of ventilation fans, hindering system flexibility and operational efficiency. Currently, to achieve ventilation and temperature / humidity regulation in each zone, numerous ventilation fans need to be installed on the sides of the greenhouse. These fans are generally fixed with bolts: multiple bolt holes are pre-drilled on the greenhouse frame and the fan flanges, and bolts are tightened one by one to secure them. While this connection method ensures the stability of the installation, it requires multiple people to align the bolt holes and tighten the bolts one by one. Especially for large greenhouses, installing dozens or even hundreds of ventilation fans consumes a lot of time. When a ventilation fan malfunctions and needs repair or replacement, the bolts must be disassembled one by one, which is cumbersome and prone to failure due to bolt corrosion or stripped threads. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0005] Therefore, one objective of this utility model is to propose a microgrid-driven multi-zone linkage temperature control greenhouse to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0006] To achieve the above objectives, one embodiment of this utility model provides a microgrid-driven multi-zone linkage temperature-controlled greenhouse, including a concrete base. A greenhouse body is built on top of the concrete base. Ventilation vents are reserved on both the left and right sides of the greenhouse body. Several symmetrically arranged base frames are fixedly connected to the top of the concrete base. Two symmetrically arranged pins are rotatably connected inside the base frames. A louver is fixedly connected between the two pins. The inner side of the louver is in contact with the outer surface of the greenhouse body. Several baffles are fixedly connected to both the left and right sides of the greenhouse body. The louver is located between two baffles. A support plate is fixedly connected to the top of each baffle. A top plate is fixedly connected between two adjacent support plates. A threaded post is threaded to one side of the top plate. A U-shaped locking frame is rotatably connected to the bottom of the threaded post through a bearing. The U-shaped locking frame is slidably connected to the louver. Several linearly arrayed locking pins are fixedly connected to the U-shaped locking frame. Each locking pin engages with the louver.

[0007] Preferably, in any of the above solutions, a ventilation fan is fixedly connected to the inside of each louver, several ventilation fans are located inside several air vents, and several base frames correspond to several air vents.

[0008] Preferably, in any of the above embodiments, the top of the U-shaped locking frame has two symmetrically arranged sliding grooves, and the U-shaped locking frame is slidably connected to the two support plates through the two sliding grooves respectively.

[0009] Preferably, in any of the above embodiments, locking bolts are rotatably connected to both the left and right sides of the U-shaped locking frame, and the threaded portions of the two locking bolts are threadedly connected to the two support plates respectively.

[0010] Preferably, in any of the above solutions, the top of the U-shaped locking frame is fixedly connected to two symmetrically arranged guide rods, both of which are slidably connected to the top plate.

[0011] Preferably, in any of the above embodiments, a sealing gasket is fixedly connected to the inner side of the louvers, and sealing grooves are provided on both the left and right sides of the main body of the greenhouse. The sealing gasket is slidably connected to the main body of the greenhouse through the sealing grooves.

[0012] Preferably, in any of the above solutions, the inner wall of the base frame has two symmetrically arranged rotating grooves, and both pins are slidably connected to the base frame through the rotating grooves.

[0013] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows: 1. When installing the ventilation fan, rotate the louvers around the pin shaft until their inner side aligns with the ventilation opening of the greenhouse structure. Rotate the threaded post on the top plate to move the U-shaped locking bracket down along the support plate until the locking pin is embedded in the louvers for fixation. For maintenance, rotate the threaded post in the opposite direction to move the U-shaped locking bracket upward, disengaging the locking pin from the louvers. Then, rotate the louvers to expose the ventilation fan for inspection or replacement. The combination of the louvers and the U-shaped locking bracket replaces the traditional bolt-fixed ventilation fan method, eliminating the need to align bolt holes and tighten bolts individually. Installation and disassembly can be completed by a single person. The locking pin's snap-fit ​​structure ensures a secure connection and avoids disassembly difficulties caused by bolt corrosion, significantly reducing ventilation fan maintenance time and improving the response efficiency of the greenhouse temperature control system.

[0014] 2. When the louvers are closed, the sealing gasket on the inner side embeds into the sealing groove of the greenhouse body, achieving a seal on the air exchange vent. When adjusting the U-shaped locking frame, the guide rod slides along the top plate, and the sliding groove restricts the vertical movement of the U-shaped locking frame along the support plate. Tightening the locking bolts further secures the position. The pin rotates smoothly within the rotating groove, ensuring smooth opening and closing of the louvers. The cooperation between the sealing gasket and the sealing groove enhances the sealing performance of the air exchange vent, preventing temperature fluctuations inside the greenhouse due to air leakage and ensuring the accuracy of multi-zone temperature control. The guide rod, sliding groove, and locking bolts together improve the stability of the U-shaped locking frame, preventing the louvers from loosening. The cooperation between the pin and the rotating groove ensures flexible opening and closing of the louvers. The overall structure balances sealing performance and operational reliability, adapting to the long-term use needs of the greenhouse. Attached Figure Description

Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited thereto.

[0018] like Figures 1 to 5 As shown, a microgrid-driven multi-zone linkage temperature-controlled greenhouse includes a concrete base 1, a greenhouse body 2 built on top of the concrete base 1, and ventilation vents 3 reserved on both the left and right sides of the greenhouse body 2. Several symmetrically arranged base frames 4 are fixedly connected to the top of the concrete base 1. Two symmetrically arranged pins 5 are rotatably connected inside the base frames 4. Louvers 6 are fixedly connected between the two pins 5. The inner side of the louvers 6 is in contact with the outer surface of the greenhouse body 2. Veneers 6 are fixedly connected to both the left and right sides of the greenhouse body 2. Several baffles 7 are provided, and a louver 6 is located between two baffles 7. A support plate 8 is fixedly connected to the top of each baffle 7. A top plate 9 is fixedly connected between two adjacent support plates 8. A threaded post 10 is threadedly connected to one side of the top plate 9. A U-shaped locking frame 11 is rotatably connected to the bottom of the threaded post 10 through a bearing. The U-shaped locking frame 11 is slidably connected to the louver 6. Several linear array locking pins 12 are fixedly connected to the U-shaped locking frame 11. All locking pins 12 are engaged with the louver 6.

[0019] As an optional technical solution of this utility model, each louver 6 is fixedly connected to an air exchange fan 13 on its inner side. Several air exchange fans 13 are located inside several air exchange vents 3, and several base frames 4 correspond to several air exchange vents 3. The louver 6 provides an installation carrier and protective barrier for the air exchange fan 13, reducing the direct erosion of the air exchange fan 13 by external dust and rainwater, extending its service life. Moreover, the air exchange fan 13 can be easily exposed or hidden by rotating the louver 6, which is convenient for installation and maintenance.

[0020] As an optional technical solution of this utility model, the top of the U-shaped locking frame 11 has two symmetrically arranged sliding grooves 14. The U-shaped locking frame 11 is slidably connected to the two support plates 8 through the two sliding grooves 14 respectively. The U-shaped locking frame 11 is slidably connected to the support plates 8 through the sliding grooves 14, which can limit the movement direction of the directional locking frame 11 and ensure that it always slides smoothly along the support plate 8 during the up and down movement, avoiding tilting or displacement of the U-shaped locking frame 11, ensuring that the locking pin 12 can be accurately embedded in the louver 6, improving the stability and reliability of the locking structure, and reducing the frictional wear between the U-shaped locking frame 11 and the support plate 8.

[0021] As an optional technical solution of this utility model, locking bolts 15 are rotatably connected to both sides of the U-shaped locking frame 11. The screw parts of the two locking bolts 15 are respectively threaded to the two support plates 8. The locking bolts 15 on both sides of the U-shaped locking frame 11 are threaded to the support plates 8. This can further reinforce the position of the louver 6 after the U-shaped locking frame 11 is fixed by the locking pin 12, prevent the U-shaped locking frame 11 from loosening or shifting due to vibration or external force, ensure that the louver 6 is always tightly attached to the main body of the greenhouse 2, avoid the decrease in ventilation efficiency or structural damage caused by insecure fixing, and enhance the overall stability of the connection.

[0022] As an optional technical solution of this utility model, the top of the U-shaped locking frame 11 is fixedly connected with two symmetrically arranged guide rods 16. Both guide rods 16 are slidably connected to the top plate 9. The guide rods 16 at the top of the U-shaped locking frame 11 are slidably connected to the top plate 9, which can provide additional guidance for the up and down movement of the U-shaped locking frame 11. Together with the slide groove 14, it further restricts the movement trajectory of the directional locking frame 11, prevents it from jamming or deviating during movement, ensures that the threaded column 10 drives the U-shaped locking frame 11 with uniform force, and improves the smoothness of operation and the accuracy of the locking position.

[0023] As an optional technical solution of this utility model, a sealing gasket 17 is fixedly connected to the inner side of the louver 6, and sealing grooves 18 are opened on both the left and right sides of the greenhouse body 1. The sealing gasket 17 is slidably connected to the greenhouse body 1 through the sealing grooves 18. The sealing gasket 17 on the inner side of the louver 6 is slidably connected to the greenhouse body 2 through the sealing grooves 18. When the louver 6 is closed, it can fill the gap between it and the greenhouse body 2, enhance the sealing of the air vent 3, prevent the temperature inside the greenhouse from fluctuating due to the infiltration of outside air or the leakage of internal air, ensure the accuracy of multi-zone linkage temperature control, and at the same time prevent rainwater and dust from entering the greenhouse through the gaps, thus protecting the environment inside the greenhouse.

[0024] As an optional technical solution of this utility model, the inner wall of the base frame 4 is provided with two symmetrically arranged rotating grooves 19. Both pins 5 are slidably connected to the base frame 4 through the rotating grooves 19. The rotating grooves 19 on the inner wall of the base frame 4 provide a stable rotation space for the pins 5, making the rotation of the louvers 6 smoother when the pins 5 drive the louvers 6, and avoiding jamming or wear caused by installation deviation. The limiting effect of the rotating grooves 19 on the pins 5 can also prevent the louvers 6 from detaching from the base frame 4 during rotation, ensuring that the louvers 6 always moves within the preset range, improving the safety and service life of the structure.

[0025] A microgrid-driven, multi-zone interconnected temperature-controlled greenhouse operates on the following principle: 1): When installing the ventilation fan 13, rotate the louver 6 around the pin 5 so that its inner side fits into the ventilation opening 3 of the greenhouse body 2.

[0026] 2): Rotate the threaded post 10 on the top plate 9 to drive the U-shaped locking bracket 11 to move down along the support plate 8 until the locking pin 12 is embedded in the louver 6 to complete the fixation.

[0027] 3): During maintenance, rotate the threaded column 10 in the opposite direction to move the U-shaped locking bracket 11 upward, and the locking pin 12 will disengage from the louver 6. Then, rotate the louver 6 to expose the ventilation fan 13 for inspection or replacement.

[0028] In summary, in this microgrid-driven multi-zone linkage temperature-controlled greenhouse, when installing the ventilation fan 13, the louver 6 is rotated around the pin 5 so that its inner side fits against the air exchange vent 3 of the greenhouse body 2; the threaded column 10 on the top plate 9 is rotated, causing the U-shaped locking frame 11 to move down along the support plate 8 until the locking pin 12 is embedded in the louver 6 to complete the fixation; during maintenance, the threaded column 10 is rotated in the opposite direction to move the U-shaped locking frame 11 up, and the locking pin 12 disengages from the louver 6, so that the louver 6 can be rotated to expose the ventilation fan 13 for inspection or replacement. The combination of louvers 6 and U-shaped locking brackets 11 replaces the traditional method of fixing ventilation fans with bolts. There is no need to align the bolt holes and tighten the bolts one by one, and a single person can complete the installation and disassembly. The snap-fit ​​structure of the locking pins 12 ensures a firm connection and avoids the disassembly difficulties caused by bolt corrosion, which greatly shortens the maintenance time of ventilation fans and improves the response efficiency of the greenhouse temperature control system. When the louvers 6 are closed, the sealing gaskets 17 on their inner side are embedded in the sealing grooves 18 of the greenhouse body 2 to achieve the sealing of the air exchange vents 3. When adjusting the U-shaped locking brackets 11, the guide rods 16 slide along the top plate 9, and the slide grooves 14 restrict the vertical movement of the U-shaped locking brackets 11 along the support plate 8. Tightening the locking bolts 15 can further fix the position. The pins 5 rotate smoothly in the rotating grooves 19 to ensure that the louvers 6 open and close smoothly. The combination of sealing gasket 17 and sealing groove 18 enhances the sealing performance of air exchange vent 3, preventing temperature fluctuations inside the greenhouse due to air leakage and ensuring the accuracy of multi-zone temperature control; guide rod 16, slide groove 14 and locking bolt 15 together improve the stability of U-shaped locking frame 11 and prevent louver 6 from loosening; the combination of pin shaft 5 and rotating groove 19 ensures that louver 6 can be opened and closed flexibly. The overall structure takes into account both sealing performance and operational reliability, and adapts to the long-term use needs of greenhouse.
