[0002] A greenhouse, also known as a hothouse, is a facility that can transmit light and keep warm (or heat up) for cultivating plants. In seasons when it is not suitable for plant growth, it can provide a greenhouse growth period and increase yields, and is mostly used for cultivating or raising seedlings of heat-loving vegetables, flowers, forest trees, etc. in low-temperature seasons.

[0003] Because the greenhouse is airtight, when planting plants, the growth of plants is affected due to poor air circulation. To improve air circulation, general greenhouses are usually equipped with ventilation windows to ventilate and exchange air inside the greenhouse.

[0004] The existing ventilation windows of greenhouses are either opened at the top of the greenhouse or set on the side of the greenhouse. If the ventilation window opened at the top of the greenhouse is opened in rainy, snowy or windy weather, it will seriously affect the growth of crops. If it is not opened for ventilation, it will also affect the growth of crops. The ventilation window set on the side is inconvenient to open, and its ventilation effect is not as good as that of the ventilation window opened at the top. Moreover, in rainy weather, rainwater will enter the inside of the greenhouse through the ventilation window.

[0005] Therefore, a new type of intelligent and scientific control greenhouse ventilation window is proposed to improve the ventilation effect while reducing the impact of weather on crops. Content of the Utility Model

[0013] Preferably, the movable heat preservation board has a radian, and the radian of the movable heat preservation board is the same as that of the top of the heat preservation covering layer, and the inner wall of the movable heat preservation board is supported by the greenhouse framework after being closed.

[0014] Preferably, the number of the active ventilation devices is multiple, and the multiple active ventilation devices are all fixed on the greenhouse framework, and the active ventilation devices are located at the bottom of the ventilation holes to support the movable heat preservation board.

Specific implementation manners

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0028] Please refer to Figures 1-5 , a new type of intelligent and scientifically controlled greenhouse ventilation window, including a greenhouse main body 1;

[0029] A passive ventilation window 2 that can be opened and closed is installed at the top of the greenhouse main body 1, and an active ventilation device 3 is installed on the side of the greenhouse main body 1. The active ventilation device 3 is an exhaust fan, and the passive ventilation window 2 is placed on the top of the active ventilation device 3 after being closed;

[0030] The greenhouse main body 1 includes a greenhouse framework 101, a heat preservation covering layer 102 is covered on the outer surface of the greenhouse framework 101, and a ventilation hole 103 is arranged at the top of the heat preservation covering layer 102;

[0031] The passive ventilation window 2 includes a movable heat preservation board 201 and a drive motor 205. A connection block 202 is fixedly connected to the bottom of the movable heat preservation board 201, a transmission rod 203 is fixedly connected between the connection blocks 202, and the transmission rod 203 penetrates through the greenhouse framework 101 and can rotate between the greenhouse frameworks 101;

[0032] The top end of the transmission rod 203 is fixedly connected with a transmission gear 204. The transmission motor 205 is fixedly connected to the greenhouse framework 101, and the output end of the transmission motor 205 meshes with the transmission gear 204. The transmission motor 205 is a servo motor and is configured with a PLC controller for control.

[0033] Through the above technical solution, by respectively installing passive ventilation windows 2 and active ventilation devices 3 above the main body 1 of the greenhouse, when the environmental conditions permit, the movable heat preservation board 201 is opened by the transmission motor 205 to achieve large-area ventilation. When the environmental conditions do not permit, the movable heat preservation board 201 is closed, and the active ventilation device 3 is started to perform active ventilation. Moreover, the top of the active ventilation device 3 is covered by the movable heat preservation board 201, and rainwater will not enter the interior of the main body 1 of the greenhouse from the position of the active ventilation device 3, achieving the effect of improving the ventilation effect and being unaffected by the weather.

[0034] Specifically, ventilation holes 103 are opened on both sides of the top of the heat preservation covering layer 102, and the end of the movable heat preservation board 201 extends and exceeds the side surface of the heat preservation covering layer 102.

[0035] Through the above technical solution, the ventilation holes 103 are opened on both sides of the top of the heat preservation covering layer 102, so that the movable heat preservation board 201 installed in the ventilation holes 103 has a larger opening space, so as to increase the exposed area of the ventilation holes 103 and improve the efficiency of air exchange;

[0036] Set the length of the movable heat preservation board 201, so that the movable heat preservation board 201 can completely cover the ventilation holes 103 after being closed and cover the top of the active ventilation device 3, reducing the influence of rainwater on the active ventilation device 3;

[0037] In order to improve the sealing performance and waterproof performance, rubber strips are provided at the contact positions between the movable heat preservation board 201 and the greenhouse framework 101 after the movable heat preservation board 201 is closed.

[0038] Specifically, the movable heat preservation board 201 has a curvature, and the curvature of the movable heat preservation board 201 is the same as the curvature of the top of the heat preservation covering layer 102, and the inner wall of the movable heat preservation board 201 is supported by the greenhouse framework 101 after the movable heat preservation board 201 is closed.

[0039] Through the above technical solution, the movable heat preservation board 201 is set to have a curvature, so that in snowy weather, the snow can slide off under the action of gravity and the curvature of the movable heat preservation board 201, avoiding snow accumulation;

[0040] Moreover, after the movable heat-insulating panel 201 is closed, it is supported by the greenhouse framework 101, which is used to enhance the compressive strength of the movable heat-insulating panel 201. Setting the arc of the movable heat-insulating panel 201 also serves the same purpose. A structure with an arc has stronger anti-deformation ability compared to a flat structure.

[0041] Specifically, the number of the active ventilation devices 3 is multiple. The multiple active ventilation devices 3 are all fixed on the greenhouse framework 101, and the active ventilation devices 3 are located at the bottom of the ventilation holes 103 to support the movable heat-insulating panel 201.

[0042] Through the above technical solution, the purpose of setting multiple active ventilation devices 3 is to improve the efficiency during ventilation and air exchange. If the number of the active ventilation devices 3 is small, the air exchange effect will decrease significantly. While the active ventilation devices 3 support the movable heat-insulating panel 201, the movable heat-insulating panel 201 will also cover the top of the active ventilation devices 3;

[0043] Thus, while increasing the resistance of the movable heat-insulating panel 201, the influence of rainwater on the active ventilation devices 3 can be avoided.

[0044] Specifically, the outer surface of the active ventilation device 3 is installed obliquely downward. The circuits of the active ventilation devices 3 on the same side are connected in series, and the circuits of the active ventilation devices 3 on both sides are led to the same switch for series connection.

[0045] Through the above technical solution, the outside of the active ventilation device 3 is installed obliquely downward, so that it is more difficult for rainwater to enter the interior of the greenhouse main body 1 through the active ventilation device 3. And when the movable heat-insulating panel 201 covers the top of the active ventilation device 3, the movable heat-insulating panel 201 will not affect the ventilation and air exchange of the active ventilation device 3;

[0046] Connecting the active ventilation devices 3 on the same side in series can improve the convenience of control. And connecting the active ventilation devices 3 on both sides in parallel and leading them to the same switch enables the active ventilation devices 3 on both sides to work separately;

[0047] And a check valve is installed at the mouth of the active ventilation device 3. The specific structure of the check valve is the same as the check device at the end of the oil fume exhaust pipe. Its function in this application is to seal the mouth of the active ventilation device 3 when the active ventilation device 3 is not working, so as to enhance the heat preservation in the heat preservation shed.

[0048] Specifically, a temperature and humidity detection device 4 is also installed on the heat preservation covering layer 102. The temperature and humidity detection device 4 is located on the outer surface of the heat preservation covering layer 102.

[0049] Through the above technical solution, the purpose of setting the temperature and humidity detection device 4 is to achieve scientific and intelligent ventilation. According to different seasons, different temperature and humidity parameters are input into the temperature and humidity detection device 4. When the temperature and humidity detection device 4 reaches the parameter threshold, a signal is input to the PLC controller of the drive motor 205 to make the drive motor 205 work, driving the movable heat preservation board 201 to open or close. This method is more scientific compared to manual control based on experience.

[0050] Specifically, the number of temperature and humidity detection devices 4 is two, and the two temperature and humidity detection devices 4 are respectively connected to the adjacent drive motors 205.

[0051] Through the above technical solution, two temperature and humidity detection devices 4 are set to increase the range of temperature and humidity detection, and the two temperature and humidity detection devices 4 respectively control the drive motors 205 on both sides to improve the control accuracy, enabling the drive motors 205 on both sides to operate differently.

[0052] During use, by respectively installing passive ventilation windows 2 and active ventilation devices 3 above the main body 1 of the greenhouse, when the environmental conditions permit, the movable heat preservation board 201 is opened by the drive motor 205 to achieve large-area ventilation. When the environmental conditions do not permit, the movable heat preservation board 201 is closed, and the active ventilation device 3 is started for active ventilation. Moreover, the top of the active ventilation device 3 is covered by the movable heat preservation board 201, and rainwater will not enter the interior of the main body 1 of the greenhouse from the position of the active ventilation device 3, achieving the effect of improving the ventilation effect and being unaffected by the weather.

[0053] By fixedly connecting the temperature and humidity detection device 4 to the outer surface of the heat preservation covering layer 102, the temperature and humidity in the air are detected by the temperature and humidity detection device 4. When the temperature and humidity are appropriate, a working signal is sent to the drive motor 205, so that the movable heat preservation board 201 is opened. When the temperature and humidity are inappropriate, the drive motor 205 is controlled to close the movable heat preservation board 201, achieving the effect of intelligent control.

[0054] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
