Description

Technical Field

[0001] This utility model relates to the field of facility horticulture technology, and more specifically, to a facility horticulture temperature and light control device. Background Technology

[0002] Facility horticulture refers to the use of artificial facilities such as greenhouses, plastic sheds, and multi-span greenhouses to create a suitable microclimate for crop growth in seasons or regions where open fields are unsuitable for horticultural crops. This enables the high-quality, high-yield, and high-efficiency production of horticultural products such as vegetables, flowers, and fruits. Greenhouses are agricultural facilities that artificially intervene in environmental conditions to provide a suitable environment for plant growth. Their core function is to simulate or optimize the natural environment, break through seasonal, climatic, and geographical limitations, and achieve off-season planting, high-efficiency production, and variety diversification of crops. However, existing technologies have some problems: existing greenhouses need to be shaded by shading nets when facing strong sunlight. However, the existing devices usually cover the shading nets manually, which is slow and can easily cause plants inside the greenhouse to be injured by the sun, affecting their growth. At the same time, existing devices rely on natural ventilation by opening windows, which cannot quickly expel the heat from the device, causing plants to be in a high-temperature state for a long time, affecting their growth. Therefore, we propose a temperature and light control device for facility horticulture. Utility Model Content

[0003] One objective of this invention is to provide a new technical solution for a temperature and light control device for facility horticulture.

[0004] According to a first aspect of this utility model, a temperature and light control device for facility horticulture is provided, comprising a housing and a top cover, the housing and the top cover being fixedly connected, a guide rod being fixedly connected to the inner wall of the housing, a movable rod being slidably connected to the guide rod, a driving assembly being provided on the housing, the driving assembly being used to drive the movable rod to slide, a baffle plate being fixedly connected to the housing, the driving assembly being disposed below the baffle plate, a shade net being provided on the movable rod, a through hole being opened on one side of the housing, a door panel being rotatably connected to the through hole, and a ventilation assembly being provided on the housing and the top cover.

[0005] Optionally, the drive assembly includes a bidirectional lead screw rotatably connected to the housing, and the movable rod is threadedly connected to the bidirectional lead screw.

[0006] Optionally, the drive assembly further includes a first motor, which is fixedly connected to the housing. A worm gear is fixedly connected to the output end of the first motor, and a worm wheel is fixedly connected to one end of the bidirectional lead screw, with the worm wheel meshing with the worm gear.

[0007] Optionally, one end of the shade net is fixedly connected to the movable rod, and the other end of the shade net is fixedly connected to the inner wall of the outer shell. A hanging ring is fixedly connected to the shade net and the hanging ring is sleeved on the guide rod.

[0008] Optionally, the ventilation assembly includes a fan, a ventilation hole is provided on one side of the housing, the fan is fixedly connected to the inner wall of the ventilation hole, and a sealing blade is rotatably connected to the inner wall of the ventilation hole.

[0009] Optionally, a hydraulic rod is rotatably connected to the outer casing, a fixed rod is rotatably connected to the movable end of the hydraulic rod, a connecting rod is fixedly connected to the fixed rod, a drive rod is rotatably connected to the connecting rod, and the sealing leaf is rotatably connected to the drive rod.

[0010] Optionally, the ventilation assembly further includes a skylight, an air outlet is provided on the upper cover, a rotating shaft is rotatably connected inside the air outlet, the skylight is fixedly connected to the rotating shaft, a second motor is fixedly connected to the upper cover, and the rotating shaft is fixedly connected to the output end of the second motor.

[0011] According to one embodiment of this disclosure, after the first motor is started, it drives the worm gear to rotate. The rotation of the worm gear drives the worm wheel to rotate, and the rotation of the worm wheel drives the bidirectional lead screw to rotate. This causes the movable rod, which is threadedly connected to the bidirectional lead screw, to slide along the guide rod under the threaded engagement. At the same time, the device has four sets of movable rods, with each pair of movable rods threadedly connected to the two ends of a set of bidirectional lead screws. This allows the device to quickly unfold the shade net when the weather suddenly clears up, thereby preventing excessive sunlight from directly hitting the plants, causing damage to the plant leaves, and affecting plant growth.

[0012] This invention utilizes a hydraulic rod to rotate a fixed rod, which in turn rotates a connecting rod, which in turn rotates a drive rod, which in turn rotates a sealing leaf. This allows the sealing leaf to open and close. When ventilation is needed via a fan, the sealing leaf is opened to allow airflow; otherwise, it is closed to prevent outside air from entering the device through the ventilation holes and causing temperature changes. Simultaneously, when the sealing leaf and the skylight are open, hot air inside the device can quickly rise and escape through the skylight, rapidly reducing the internal temperature and preventing excessively high temperatures that could negatively impact plant growth.

[0013] Other features and advantages of the present invention will become clear from the following detailed description of exemplary embodiments of the present invention with reference to the accompanying drawings. Attached Figure Description

[0018] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0019] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0020] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0021] like Figure 1-6As shown, a temperature and light control device for facility horticulture includes an outer shell 1 and an upper cover 2. Both the outer shell 1 and the upper cover 2 are composed of a stainless steel frame and transparent glass. The main functions of the outer shell 1 and the upper cover 2 are to provide strength and stability for the entire device, support the covering material, and withstand loads such as wind, snow, and crop hanging. At the same time, they also provide a carrier for installing various equipment.

[0022] Furthermore, the outer shell 1 and the upper cover 2 are fixedly connected, a guide rod 3 is fixedly connected to the inner wall of the outer shell 1, a movable rod 4 is slidably connected to the guide rod 3, and a drive assembly 5 is provided on the outer shell 1 to drive the movable rod 4 to slide.

[0023] Specifically, the drive assembly 5 includes a bidirectional lead screw 51, which is rotatably connected to the housing 1, and the movable rod 4 is threadedly connected to the bidirectional lead screw 51.

[0024] Furthermore, the drive assembly 5 also includes a first motor 52, which is fixedly connected to the housing 1. A worm gear 53 is fixedly connected to the output end of the first motor 52, and a worm wheel 54 is fixedly connected to one end of the bidirectional lead screw 51. The worm wheel 54 meshes with the worm gear 53.

[0025] Specifically, after the first motor 52 starts, it drives the worm gear 53 to rotate. The rotation of the worm gear 53 drives the worm wheel 54 to rotate. The rotation of the worm wheel 54 drives the bidirectional lead screw 51 to rotate. This causes the movable rod 4, which is threadedly connected to the bidirectional lead screw 51, to slide along the guide rod 3 under the threaded engagement. At the same time, the device has four sets of movable rods 4. Every two sets of movable rods 4 are threadedly connected to the two ends of a set of bidirectional lead screws 51. This allows the device to quickly unfold the shade net 6 when the weather suddenly clears up, thereby preventing excessive sunlight from directly hitting the plants, causing damage to the plant leaves, and affecting plant growth.

[0026] Furthermore, a guide plate 9 is fixedly connected to the outer casing 1, and the drive assembly 5 is located below the guide plate 9. The guide plate 9 is used to concentrate rainwater onto the drive assembly 5, which affects the service life of the drive assembly 5.

[0027] Furthermore, a sunshade net 6 is provided on the movable rod 4. One end of the sunshade net 6 is fixedly connected to the movable rod 4, and the other end of the sunshade net 6 is fixedly connected to the inner wall of the outer shell 1. A hanging ring 10 is fixedly connected to the sunshade net 6 and is sleeved on the guide rod 3.

[0028] Specifically, the two ends of the shade net 6 are fixed to the outer shell 1 and the movable rod 4 respectively, so that the movable rod 4 can control the unfolding or rolling of the shade net 6 when it moves. The hanging ring 10 fixed on the shade net 6 is used to facilitate the opening and closing of the shade net 6, while preventing the shade net 6 from sagging.

[0029] Furthermore, a through hole is provided on one side of the outer casing 1, and a door panel 7 is rotatably connected inside the through hole. The door panel 7 is used for the entry and exit of the device. Ventilation components 8 are provided on the outer casing 1 and the top cover 2.

[0030] Specifically, the ventilation assembly 8 includes a fan 81, a ventilation hole is provided on one side of the housing 1, the fan 81 is fixedly connected to the inner wall of the ventilation hole, and a sealing blade 82 is rotatably connected to the inner wall of the ventilation hole.

[0031] Furthermore, a hydraulic rod 83 is rotatably connected to the outer casing 1, a fixed rod 84 is rotatably connected to the movable end of the hydraulic rod 83, a connecting rod 85 is fixedly connected to the fixed rod 84, a drive rod 89 is rotatably connected to the connecting rod 85, and the sealing leaf 82 is rotatably connected to the drive rod 89.

[0032] Specifically, by activating the hydraulic rod 83, the fixed rod 84 is rotated. After the fixed rod 84 rotates, the connecting rod 85 rotates. After the connecting rod 85 rotates, the drive rod 89 rotates. After the drive rod 89 rotates, the sealing leaf 82 rotates, thereby realizing the opening and closing of the sealing leaf 82. When ventilation is required through the fan 81, the sealing leaf 82 is opened to allow ventilation of the device. When ventilation is not required, the sealing leaf 82 is closed to prevent outside air from entering the device through the ventilation hole and causing changes in the temperature inside the device.

[0033] Furthermore, the ventilation assembly 8 also includes a skylight 86, an air outlet is provided on the upper cover 2, a rotating shaft 87 is rotatably connected inside the air outlet, the skylight 86 is fixedly connected to the rotating shaft 87, a second motor 88 is fixedly connected to the upper cover 2, and the rotating shaft 87 is fixedly connected to the output end of the second motor 88.

[0034] Specifically, by starting the second motor 88, the rotating shaft 87 is driven to rotate. After the rotating shaft 87 rotates, the skylight 86 will rotate, thereby controlling the opening and closing of the skylight 86. When the sealing leaf 82 and the skylight 86 are opened at the same time, the hot air inside the device can be quickly transferred upward and discharged from the skylight 86, thereby quickly reducing the temperature inside the device and avoiding excessively high temperatures from affecting plant growth.

[0035] Furthermore, during ventilation, both the sealing leaf 82 and the skylight 86 remain tilted, which can effectively prevent rainwater from entering the device, allowing the device to continue ventilation even in rainy weather and improving the device's adaptability.

[0036] The aforementioned temperature and light control device for facility horticulture, after the first motor 52 is started, drives the worm gear 53 to rotate. The rotation of the worm gear 53 drives the worm wheel 54 to rotate, and the rotation of the worm wheel 54 drives the bidirectional lead screw 51 to rotate. This causes the movable rod 4, which is threadedly connected to the bidirectional lead screw 51, to slide along the guide rod 3 under the threaded engagement. At the same time, the device has four sets of movable rods 4, with each pair of movable rods 4 threadedly connected to the two ends of a set of bidirectional lead screws 51. This allows the device to quickly unfold the shade net 6 when the weather suddenly clears up, thereby preventing excessive sunlight from directly hitting the plants, causing damage to the plant leaves, and affecting plant growth.

[0037] This invention utilizes a hydraulic rod 83 to rotate a fixed rod 84. The rotation of the fixed rod 84 then rotates a connecting rod 85, which in turn rotates a drive rod 89. This rotation of the drive rod 89 causes the sealing leaf 82 to rotate, thus opening and closing the sealing leaf 82. When ventilation is required via the fan 81, the sealing leaf 82 is opened to allow airflow; otherwise, it is closed to prevent outside air from entering the device through the ventilation holes and causing temperature changes. Simultaneously, when the sealing leaf 82 and the skylight 86 are opened, hot air inside the device can quickly rise and be exhausted through the skylight 86, rapidly reducing the temperature inside the device and preventing a slow temperature drop that could lead to excessively high temperatures that could negatively impact plant growth.
