Description

Technical Field

[0001] This utility model relates to the field of agricultural greenhouse technology, and in particular to a ventilation window with automatic temperature and humidity control and ventilation volume control. Background Technology

[0002] As we all know, greenhouses provide a suitable warm environment for plants. Typically, greenhouses use a bamboo and steel frame structure, covered with one or more layers of insulating plastic film. This film effectively prevents the loss of carbon dioxide produced during vegetable growth, achieving the necessary insulation. With the continuous maturation and development of greenhouse technology, not only vegetables can be grown, but also fruits. For example, grape cultivation in greenhouses has evolved into intelligent grape cultivation.

[0003] The ideal temperature for grape cultivation is typically between 15-30 degrees Celsius, with humidity maintained at 60%-70%. Sufficient sunlight is also essential for photosynthesis and fruit ripening. Therefore, in implementing smart grape cultivation technology, maintaining suitable temperature and humidity within the greenhouse is crucial. The most common method for adjusting temperature and humidity is ventilation. However, current greenhouse ventilation windows are often manually operated and the ventilation volume cannot be adjusted, making temperature and humidity regulation extremely inconvenient and unsuitable for smart grape cultivation. Utility Model Content

[0004] This utility model provides a ventilation window with automatic temperature and humidity control, solving the problem of manual adjustment of ventilation windows in greenhouses and the inability to adjust the ventilation volume. According to the temperature and humidity inside the greenhouse, the window is opened and closed by a drive motor driving a rotating rod in conjunction with a connecting rod assembly, and the temperature and humidity are changed by adjusting the ventilation volume.

[0005] This utility model is achieved through the following technical solution:

[0006] A ventilation window with automatic temperature and humidity control ventilation volume includes a ventilation window body, a drive motor, and temperature and humidity sensors installed inside the greenhouse.

[0007] The ventilation window body includes a window frame, and multiple connecting rods are vertically installed on the inner side of the window frame. The multiple connecting rods are connected to the frame of the greenhouse.

[0008] The inner side of the window frame is rotatably connected to two vertically parallel rotating rods, and the output shaft of the drive motor is connected to one of the rotating rods.

[0009] The outer side of the window frame is fitted with a window sash, and the inner side of the window sash is connected to two rotating rods through multiple sets of connecting rod assemblies. Each set of connecting rod assemblies includes an upper connecting rod and a lower connecting rod.

The rear end of the lower connecting rod is fixed to the rotating rod located below, and the front end is hinged to the inner side of the window sash.

[0010] Furthermore, the window frame is made of aluminum alloy sheet metal, and support plates are provided on the left and right sides of the inner side of the window frame. The two ends of the two rotating rods are connected to the support plates through sliding bearing assemblies.

[0011] The output shaft of the drive motor is connected to one end of the rotating rod located below via a coupling.

[0012] Furthermore, both the upper and lower connecting rods are provided with bushings at their rear ends. The bushings have threaded holes and are threaded with fastening bolts. The bushings are fitted onto the rotating rod and fixed by the fastening bolts.

[0013] Furthermore, the inner sides of the upper and lower borders of the window frame are provided with horizontally distributed T-shaped grooves, and the upper and lower ends of the connecting rod are respectively connected to the upper and lower distributed T-shaped grooves through pressure block assemblies.

[0014] Furthermore, the pressure block assembly includes a pressure block body and two long bolts. The end face of the pressure block body is provided with a groove that cooperates with the rotating rod.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0030] In the description of the utility model, it should be understood that the terms "front", "rear", "up", "down", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0031] like Figure 1-3 As shown, this embodiment discloses a ventilation window with automatic temperature and humidity control, including a ventilation window body 1, a drive motor, a temperature sensor, and a humidity sensor. The temperature sensor and humidity sensor are installed inside the greenhouse to monitor the temperature and humidity inside the greenhouse, which serves as the data basis for opening and closing the ventilation window body 1.

[0032] The ventilation window body 1 includes a window frame 2, a window sash 3, a rotating rod 4, a connecting rod 5, and a connecting rod assembly. The window frame 2 is made of aluminum alloy sheet metal. Support plates 6 are respectively set on the left and right sides of the inner side of the window frame 2. There are two rotating rods 4, and the two ends of the two rotating rods 4 are connected to the support plates 6 through sliding bearing assemblies. The two rotating rods 4 are distributed parallel to each other vertically. The drive motor is a servo motor. The base of the drive motor is fixed on the frame of the greenhouse. The output shaft of the drive motor is connected to one end of the rotating rod 4 located below through a coupling.

[0033] The window sash 3 is mounted on the outside of the window frame 2. The frame of the window sash 3 is made of aluminum alloy plate, and a greenhouse film is fixed in the middle of the frame of the window sash 3. The inside of the window sash 3 is connected to two rotating rods 4 through multiple sets of connecting rod assemblies. The number of connecting rod assemblies is selected according to the width of the window sash 3. In this embodiment, there are two sets of connecting rod assemblies. Each set of connecting rod assemblies includes an upper connecting rod 7 and a lower connecting rod 8. The front ends of the upper connecting rod 7 and the lower connecting rod 8 are hinged to the inside of the window sash 3 by hinges and pins. The rear ends of the upper connecting rod 7 and the lower connecting rod 8 are provided with bushings 9. Threaded holes are machined on the side walls of the bushings 9 and fastening bolts are threaded onto them. The bushings 9 are mounted on the rotating rods 4 and fixed by the fastening bolts, so that the rear ends of the upper connecting rod 7 and the lower connecting rod 8 are fixed to the two rotating rods 4 distributed vertically.

[0034] Multiple connecting rods 5 are vertically installed on the inner side of the window frame 2. These connecting rods 5 are connected to the greenhouse frame to fix the window frame 2 to the greenhouse. Because the spacing between the greenhouse frames varies, the position of the connecting rods 5 relative to the window frame 2 needs to be adjusted. Therefore, horizontally distributed T-shaped grooves 10 are provided on the inner sides of both the upper and lower edges of the window frame 2. The upper and lower ends of the connecting rods are connected to the T-shaped grooves 10 via pressure block assemblies. The pressure block assembly includes a pressure block body 11 and two long bolts 12. The end face of the pressure block body 11 is machined with a groove that mates with the rotating rod 4. The head end of the long bolt 12 is welded with a positioning plate 13 that fits within the T-shaped groove 10. The positioning plate 13 can slide relative to the T-shaped groove 10 to adjust its position. When adjusted to the appropriate position, the groove of the pressure block body 11 presses down on the connecting rod 5, allowing the tail end of the long bolt 12 to pass through the pressure block body 11 and be secured by a nut threaded connection. A screen is also installed on the inner side of the window frame 2 to prevent birds and insects from flying in through the window. To improve sealing, rubber pads are installed at the contact edges between the window frame 2 and the window sash 3.

[0035] like Figure 4-5As shown in the figure, the specific working process of the ventilation window with automatic temperature and humidity control ventilation volume described in this embodiment is as follows:

[0036] Temperature and humidity sensors monitor the greenhouse temperature and humidity in real time. When the temperature or humidity exceeds the set range, the ventilation window needs to be opened. The drive motor rotates the rotating rod 4, and the upper connecting rod 7 and lower connecting rod 8 together drive the window sash 3 to open outward, achieving automatic ventilation. By controlling the rotation angle of the rotating rod 4, the opening distance of the window sash 3 can be controlled, thereby adjusting the ventilation volume. When it rains, the drive motor rotates the rotating rod 4 in the opposite direction, retracting the window sash 3 into the window frame 2, thus closing it. This utility model can automatically control the opening and closing of the window sash 3 and the opening distance of the window sash 3, making it more convenient to use. At the same time, it ensures the ventilation volume, temperature, and humidity in the greenhouse. It can effectively ventilate while maintaining the temperature and humidity in the greenhouse, and adjust the temperature and humidity in the greenhouse by changing the ventilation volume.
