Description

Technical Field

[0001] The utility model relates to the technical field of agricultural equipment and facilities, in particular to a greenhouse with an intelligent skylight. Background Technique

[0002] With the development of China's economy and the adjustment of the rural planting structure, the cultivation of greenhouses has developed rapidly. Using greenhouses to cultivate crops such as vegetables not only improves the economic benefits of vegetable farmers but also has significant social benefits. The solar greenhouse is a unique type of greenhouse in the northern region of China. When there is sufficient sunlight during the day, the temperature and humidity inside the greenhouse will reach a relatively high level, which is not conducive to the growth of crops. At this time, it is necessary to ventilate and cool the greenhouse.

[0003] In the existing greenhouses, the ventilation and cooling of the greenhouse are mainly achieved by using a rolling film device to roll up part of the film. However, there are mainly two problems with using a rolling film device. Firstly, the rolling film shaft that has been used for a long time is prone to bending and deformation, which will cause the greenhouse to be unable to be strictly sealed. Secondly, after part of the film is rolled up, birds or pests from the outside will enter the greenhouse through the ventilation gaps, resulting in damage to crops such as vegetables. Content of the Utility Model

[0004] The purpose of the utility model is to solve the problems in the prior art that the rolling film shaft that has been used for a long time is prone to bending and deformation, which will cause the greenhouse to be unable to be strictly sealed, and after part of the film is rolled up, birds or pests from the outside will enter the greenhouse through the ventilation gaps, resulting in damage to crops such as vegetables, and to propose a greenhouse with an intelligent skylight.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A greenhouse with an intelligent skylight includes a frame, and a plastic film is arranged on the frame. It further includes: a ventilation frame fixedly connected to the frame, wherein a movable plate is slidably connected to the ventilation frame, a screen is fixedly connected to the end of the movable plate, and the connecting end of the screen is connected to the inner wall of the ventilation frame through an elastic component; a driving part for driving the movable plate to move.

[0007] Preferably, in order to facilitate the movement of the movable plate, the driving part includes a lead screw rotatably connected to the ventilation frame, a movable block is threadedly connected to the lead screw, and the movable block is in contact with the inner wall of the ventilation frame, and the movable plate is fixedly connected to the movable block.

[0008] Furthermore, in order to facilitate the forward and reverse rotation of the lead screw, a forward and reverse motor is fixedly connected to the ventilation frame, and the lead screw is fixedly connected to the output end of the forward and reverse motor.

[0009] For the convenience of quickly closing the movable plate, preferably, a rain drop sensor is fixedly connected to the ventilation frame, and the rain drop sensor is arranged above the plastic film. A controller is fixedly connected to the bottom of the ventilation frame, and the controller is electrically coordinated with the rain drop sensor and the forward and reverse motor respectively.

[0010] For the convenience of draining the water in the ventilation frame, preferably, a drainage box is fixedly connected to the bottom of the inclined end of the ventilation frame, and the ventilation frame is communicated with the drainage box through a drainage hole.

[0011] For improving the connection toughness of the screen mesh, preferably, the elastic component includes a spring. A connecting plate is fixedly connected to the screen mesh, and two ends of the spring are fixedly connected to the connecting plate and the ventilation frame respectively.

[0012] Compared with the prior art, the utility model provides a greenhouse with an intelligent skylight, which has the following beneficial effects:

[0013] 1. For the greenhouse with an intelligent skylight, the movable plate can be used for a long time without bending and deforming. The outside of the ventilation frame is connected with the plastic film. The screen mesh can intercept birds or pests outside, prevent them from entering the greenhouse through the ventilation gaps of the ventilation frame, and prevent vegetables and other crops from being damaged.

[0014] 2. For the greenhouse with an intelligent skylight, after the rain drop sensor detects that the rain drops or humidity exceeds a certain threshold, the sensor will send a signal to the controller. After receiving the signal, the controller will start the forward and reverse motor according to the preset program logic (the preset program logic is the prior art). The controller will output a corresponding signal to drive the forward and reverse motor to rotate counterclockwise, so that the movable plate seals the ventilation frame, thereby preventing rain water from entering the inside of the greenhouse.

[0015] 3. For the greenhouse with an intelligent skylight, the inclined movable plate will guide the rain water to the lower left. At this time, the rain water will flow into the drainage box through the drainage hole, drain the rain water, reduce the weight pressure of the rain water on the plastic film, and improve the drainage effect of the ventilation frame.

[0016] Parts not involved in the device are the same as the prior art or can be realized by adopting the prior art. The movable plate in the utility model can be used for a long time without bending and deforming. The outside of the ventilation frame is connected with the plastic film. The screen mesh can intercept birds or pests outside, prevent them from entering the greenhouse through the ventilation gaps of the ventilation frame, and prevent vegetables and other crops from being damaged.

[0024] Embodiment:

[0025] Referring to Figures 1 - 4 , a greenhouse with an intelligent skylight includes a frame 1, and a plastic film is provided on the frame 1, and the plastic film covers the upper surface of the frame 1 to form a greenhouse. And a ventilation frame 2 is fixedly installed on the frame 1 through a connecting rod, a movable plate 3 is slidably connected to the ventilation frame 2, an end of the movable plate 3 is fixedly connected to a screen 5, and a connecting end of the screen 5 is connected to the inner wall of the ventilation frame 2 through an elastic component; a driving part for driving the movable plate 3 to move.

[0026] The above elastic component includes a spring 502. A connecting plate 501 is fixedly connected to the screen 5, and two ends of the spring 502 are respectively fixedly connected to the connecting plate 501 and the ventilation frame 2.

[0027] The movable plate 3 is a transparent glass plate. The position of the movable plate 3 is driven by a driving part to move, so that the air-permeable frame 2 can be in an open or closed state. When the movable plate 3 moves obliquely upward towards the frame 1, at this time, the screen net 5 at the end of the movable plate 3 will move synchronously and will be stretched under the limiting action of the spring 502, improving the connection toughness of the screen net 5, and then intercepting the open air-permeable frame 2 to prevent birds and pests from entering the greenhouse. Moreover, the movable movable plate 3 can be used for a long time without bending and deforming. In addition, the outside of the air-permeable frame 2 is connected to the plastic film, and the movable plate 3 is arranged below the plastic film. The screen net 5 can intercept birds or pests outside to prevent them from entering the greenhouse through the air-permeable gaps of the air-permeable frame 2 and prevent crops such as vegetables from being damaged.

[0028] Further, the above-mentioned driving part includes a lead screw 201 rotatably connected to the air-permeable frame 2. A movable block 202 is threadedly connected to the lead screw 201, and the movable block 202 is in contact with the inner wall of the air-permeable frame 2. The movable plate 3 is fixedly connected to the movable block 202. A forward and reverse motor 6 is fixedly connected to the air-permeable frame 2, and the lead screw 201 is fixedly connected to the output end of the forward and reverse motor 6.

[0029] When the inside of the greenhouse needs to be ventilated, the forward and reverse motor 6 rotates clockwise, causing the lead screw 201 to rotate clockwise, thereby driving the movable block 202 to move on the air-permeable frame 2. At the same time, the movable block 202 drives the movable plate 3 to move obliquely upward towards the air-permeable frame 2. At this time, the screen net 5 will be stretched synchronously. When the inside of the greenhouse does not need to be ventilated, the forward and reverse motor 6 rotates counterclockwise, causing the lead screw 201 to rotate counterclockwise, thereby driving the movable block 202 to move on the air-permeable frame 2. At the same time, the movable block 202 drives the movable plate 3 to move from the oblique upper part of the air-permeable frame 2 towards the oblique lower part for resetting, and the screen net 5 will retract during this process.

[0030] A rain drop sensor 4 is fixedly connected to the air-permeable frame 2, and the rain drop sensor 4 is arranged above the plastic film. A controller 8 is fixedly connected to the bottom of the air-permeable frame 2, and the controller 8 is electrically connected to the rain drop sensor 4 and the forward and reverse motor 6 respectively.

[0031] When the rain drop sensor 4 detects raindrops or the humidity exceeds a certain threshold, the sensor will send a signal to the controller 8. After receiving the signal, the controller 8 will start the forward and reverse motor 6 according to the preset program logic. The preset program logic is prior art, and the controller 8 will output a corresponding signal to drive the forward and reverse motor 6 to rotate counterclockwise, so that the movable plate 3 blocks the air-permeable frame 2, thereby preventing rainwater from entering the inside of the greenhouse.

[0032] In addition, a drainage box 7 is fixedly connected to the bottom of the inclined end of the air-permeable frame 2, and the air-permeable frame 2 is communicated with the drainage box 7 through a drainage hole 701.

[0033] When it is rainy, the inclined movable plate 3 will guide the rainwater to the lower right, and at this time the rainwater will flow into the drainage box 7 through the drainage holes 701 to drain the rainwater, reduce the weight pressure of the rainwater on the plastic film, and improve the drainage effect of the ventilation frame 2.

[0034] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
