Description

Technical Field

[0001] This utility model relates to the field of agricultural planting technology, and in particular to a constant temperature vegetable planting greenhouse. Background Technology

[0002] A vegetable greenhouse is an artificial agricultural facility, typically covered with plastic film or glass, designed to create a relatively stable and controllable local environment for vegetable growth. These greenhouses effectively block adverse weather conditions such as extreme cold, heat, strong winds, heavy rain, and frost, while allowing sunlight to penetrate through the covering material, providing the necessary light for the vegetables. They are usually equipped with ventilation and irrigation systems, and sometimes supplemental lighting, heating, or cooling equipment to regulate temperature, humidity, and light intensity to meet the growth needs of different vegetable varieties. In this way, vegetable greenhouses can significantly extend the growing season of vegetables, even enabling off-season cultivation, increasing yield and quality, and reducing the occurrence of pests and diseases. It is a widely adopted and highly efficient production model in modern facility agriculture.

[0003] In modern agriculture, greenhouses are widely used for vegetable cultivation, providing a relatively stable environment for vegetable growth. However, existing greenhouses generally suffer from a significant technical deficiency: they cannot adjust ventilation performance in real time according to the internal temperature. When the temperature inside the greenhouse rises, the ventilation intensity cannot be adjusted based on real-time temperature changes. This makes it difficult for vegetables with high requirements for their growing environment to obtain suitable growing conditions, thus affecting their healthy growth and restricting the improvement of vegetable yield and quality. Utility Model Content

[0004] One objective of this invention is to provide a constant-temperature vegetable growing greenhouse. This invention addresses the problem mentioned in the background that when the temperature inside the greenhouse rises, the ventilation intensity cannot be adjusted according to real-time temperature changes. This makes it difficult for vegetables with high requirements for their growing environment to obtain suitable growing conditions, thereby affecting their healthy growth and restricting the improvement of vegetable yield and quality.

[0005] A constant-temperature vegetable greenhouse according to an embodiment of the present invention includes a greenhouse frame and an adjustment mechanism installed inside the greenhouse frame for adjusting the ventilation mechanism switch. The ventilation mechanism includes a window frame and a sealing plate. The sealing plate is hinged to the inside of the window frame. The window frame is fixedly installed on the upper parts of both sides of the greenhouse frame. The adjustment mechanism includes a thermal expansion material, a right-angled top rod, and a transmission rod. A fixed frame is fixedly connected to the lower inner part of the greenhouse frame. The thermal expansion material is fixedly installed in the lower inner part of the fixed frame. A top plate is movably connected to the upper inner part of the fixed frame. The right-angled top rod is fixedly installed on the upper surface of the top plate. The transmission rod is movably connected between the upper end of the right-angled top rod and one side surface of the sealing plate.

[0006] Preferably, the thermal expansion material is a polyolefin thermal shrinkage material.

[0007] Preferably, the upper end of the right-angled top rod is rotatably connected to one end of the transmission rod via a first rotating structure, and the other end of the transmission rod is rotatably connected to one side surface of the sealing plate via a second rotating structure.

[0008] Preferably, a fixing rod is fixedly connected to the upper inner side of the greenhouse frame, and the right-angled top rod is slidably connected to the surface of the fixing rod.

[0009] Preferably, a fixing ring is fixedly connected to the side surface of the right-angled top rod, and a spring structure is installed between the upper surface of the fixing ring and the lower surface of the fixing rod, the spring structure being disposed on the outside of the right-angled top rod.

[0010] Preferably, a greenhouse film is fixedly connected to the surface of the greenhouse frame.

[0011] Preferably, both ends of the greenhouse frame are hinged with entrances and exits, and several sets of ventilation openings are provided through the upper part of both sides of the greenhouse frame.

[0012] Preferably, a temperature and humidity display screen is installed on the upper part of the entrance / exit, and a temperature and humidity sensor is fixedly installed on the inner side of the greenhouse frame.

[0013] The beneficial effects of this utility model are:

[0014] This invention utilizes an adjustable mechanism. Under normal use, the greenhouse temperature gradually increases due to direct sunlight. When the temperature inside the greenhouse becomes too high, the thermal expansion material installed inside the fixed frame expands due to heat, lifting the top plate upwards. The top plate, via a right-angled top rod and a transmission rod, pushes the sealing plate outwards, ventilating the interior space and gradually lowering the temperature. At this time, the spring structure is compressed between the fixed ring and the fixed rod. As the temperature inside the greenhouse gradually decreases, the thermal expansion material contracts at low temperatures, pushing the right-angled top rod downwards through the spring structure. This pulls the upper transmission rod and the sealing plate inwards, closing the opening at the ventilation mechanism's window frame and making the greenhouse interior nearly sealed. With sunlight, the temperature inside the greenhouse gradually increases. The system automatically adjusts ventilation according to the temperature: opening ventilation to cool down when the temperature is high and closing it to maintain warmth when the temperature is low, providing a stable and suitable growing environment for vegetables.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0022] refer to Figure 1-4A constant-temperature vegetable greenhouse includes a greenhouse frame 1 and an adjustment mechanism 7 installed inside the greenhouse frame 1 for adjusting the opening and closing of a ventilation mechanism 6. The ventilation mechanism 6 includes a window frame 601 and a sealing plate 602. The sealing plate 602 is hinged to the inside of the window frame 601, and the window frame 601 is fixedly installed on the upper sides of both sides of the greenhouse frame 1. The adjustment mechanism 7 includes a thermal expansion material 702, a right-angled top rod 704, and a transmission rod 707. A fixed frame 701 is fixedly connected to the lower inner side of the greenhouse frame 1. The thermal expansion material 702 is fixedly installed in the lower inner part of the fixed frame 701. A top plate 703 is movably connected to the upper inner part of the fixed frame 701. The right-angled top rod 704 is fixedly installed on the upper surface of the top plate 703. The transmission rod 707 is movably connected between the upper end of the right-angled top rod 704 and one side surface of the sealing plate 602. Through the adjustment mechanism 7, the temperature inside the greenhouse gradually increases under normal use due to direct sunlight. When the temperature is too high, the thermal expansion material 702 installed inside the fixed frame 701 expands due to heat, pushing the top plate 703 upward. The top plate 703, through the right-angled top rod 704 and the transmission rod 707, pushes the sealing plate 602 outward, ventilating the interior space of the greenhouse and gradually lowering the temperature inside. At this time, the spring structure 710 is squeezed between the fixed ring 709 and the fixed rod 705. As the temperature inside the greenhouse gradually decreases, the thermal expansion material 702 contracts at low temperature, pushing the right-angled top rod 704 downward through the spring structure 710, thereby pulling the upper transmission rod 707 and the sealing plate 602 to rotate inward. The sealing plate 602 closes the opening at the window frame 601 of the ventilation mechanism 6, making the interior of the greenhouse tend to be sealed. Through the radiation of sunlight, the temperature inside the greenhouse gradually rises. The ventilation is automatically adjusted according to the temperature. When the temperature is high, ventilation is turned on to cool down; when the temperature is low, ventilation is turned off to keep warm, providing a stable and suitable growing environment for vegetables.

[0023] Example 1: The thermal expansion material 702 is a polyolefin heat shrinkable material. The upper end of the right-angle top rod 704 is rotatably connected to one end of the transmission rod 707 through the first rotating structure 706. The other end of the transmission rod 707 is rotatably connected to one side surface of the sealing plate 602 through the second rotating structure 708. A fixing rod 705 is fixedly connected to the upper inner side of the greenhouse frame 1. The right-angle top rod 704 is slidably connected to the surface of the fixing rod 705. A fixing ring 709 is fixedly connected to the side surface of the right-angle top rod 704. A spring structure 710 is installed between the upper surface of the fixing ring 709 and the lower surface of the fixing rod 705. The spring structure 710 is located on the outside of the right-angle top rod 704.

[0024] Example 2: A greenhouse film 2 is fixedly connected to the surface of the greenhouse frame 1. Doors and exits 3 are hinged to both ends of the greenhouse frame 1. Several sets of ventilation openings 4 are opened through the upper part of both sides of the greenhouse frame 1. A temperature and humidity display screen 5 is installed on the upper part of the door and exit 3. A temperature and humidity sensor is fixedly installed on the inner side of the greenhouse frame 1. The temperature and humidity sensor and the temperature and humidity display screen 5 can display the temperature and humidity inside the greenhouse in real time, thereby ensuring the normal growth of vegetables inside the greenhouse.

[0025] In use, the thermal expansion material 702 in the lower part of the fixed frame 701 inside the inner side of the greenhouse frame 1 begins to expand as the internal temperature of the greenhouse gradually rises due to the absorption of external sunlight. The expanded thermal expansion material 702 pushes the top plate 703 in the upper part of the fixed frame 701 upwards. The right-angled top rod 704 on the surface of the top plate 703 moves accordingly. Its upper end is connected to one end of the transmission rod 707 through the first rotating structure 706, and the other end of the transmission rod 707 is connected to one side surface of the sealing plate 602 through the second rotating structure 708. Thus, the transmission rod 707 drives the sealing plate 602, which is hinged to the inside of the window frame 601, to open outwards. The window frame 601 is fixedly installed on the upper part of both sides of the greenhouse frame 1. After the sealing plate 602 is opened, the ventilation mechanism 6 is activated, and the internal space of the greenhouse is ventilated. The heat dissipates, and the internal temperature gradually decreases. During this process, the fixing ring 709 fixedly connected to the side surface of the right-angled top rod 704... During upward movement, the material is compressed by the fixed rod 705 and the spring structure 710. As the internal temperature of the greenhouse gradually decreases, the thermal expansion material 702 begins to contract at low temperatures. Under the action of the spring structure 710, the right-angled top rod 704 is pushed downward. The right-angled top rod 704 moves down and pulls the transmission rod 707. The transmission rod 707 then pulls the sealing plate 602 to rotate inward. The sealing plate 602 closes the opening at the window frame 601 of the ventilation mechanism 6, and the inside of the greenhouse tends to be closed. Subsequently, through the radiation of sunlight, the internal temperature of the greenhouse will gradually rise again. This cycle continues, and the ventilation is automatically adjusted according to the temperature. When the temperature is high, ventilation is turned on to cool down, and when the temperature is low, ventilation is turned off to keep warm. At the same time, the greenhouse film 2 on the surface of the greenhouse frame 1, the door and exit doors 3 at both ends, and the ventilation opening 4 at the top work together. The temperature and humidity sensor on the inside of the greenhouse frame 1 and the temperature and humidity display screen 5 on the top of the door and exit doors 3 display the internal temperature and humidity in real time to ensure the normal growth of vegetables.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
