Description

Technical Field

[0001] The invention relates to the technical field of greenhouses, and in particular to intelligent greenhouse ventilation equipment. Background Art

[0002] Smart greenhouse is a greenhouse facility equipped with intelligent control system, which can automatically adjust environmental factors such as temperature, humidity, light, carbon dioxide concentration, etc., and use modern technical means (such as sensors, automation equipment, computer software, etc.) for precision agricultural production. In its use, ventilation equipment is indispensable. Since the greenhouse is a closed place, the air inside cannot circulate normally to ensure freshness, so ventilation equipment is needed to achieve the exchange and regulation of the internal air.

[0003] For example, the invention patent with the publication number CN118489467A discloses an intelligent greenhouse ventilation device. In view of the problem that the current ventilation equipment is difficult to maintain uniform temperature and humidity for the air conditioning of the middle and lower layers of the greenhouse with the air on the top layer, the following scheme is proposed, including a fan cylinder, the top of which is fixed with a vertically arranged fixed air intake square tube, the top of which is sleeved with a vertically arranged movable air intake square tube, and one end of the fan cylinder is provided with a first closing mechanism. The invention can control the position of the air intake rod to a horizontal or vertical state through the control of the air intake rod drive block. In the horizontal state, when the fan controls the circulation in the greenhouse, the air at the top of the greenhouse is circulated. When the air intake rod is in a vertical state, the air intake rod draws the air at the bottom of the greenhouse to the top, realizing the air circulation of the high and low positions in the greenhouse, and improving the unified effect of regulating the air temperature and humidity in the greenhouse.

[0004] However, the above solution still has some problems: first, the angle of the airflow from the air outlet cannot be adjusted, which affects the air circulation inside the greenhouse; second, the air inlet directly introduces external airflow. When the external humidity is high, such as when it rains, it will cause humidity in the greenhouse and cause crop rot. Summary of the invention

[0032] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0033] like Figures 1 to 8As shown, the present invention provides an intelligent greenhouse ventilation device, including a mounting frame 1 fixedly installed on the side or top of the greenhouse, a mounting plate 2 fixedly installed in the mounting frame 1, a wind hole is arranged in the center of the mounting plate 2, a driving motor 3 is installed on the top of the mounting plate 2, a rotating mounting part 4 is fixedly installed at the center of the mounting plate 2 through a bracket 15, a driving shaft 5 is rotatably installed on the rotating mounting part 4, a blade 6 is fixedly installed on one end of the driving shaft 5, a pulley 7 is fixedly sleeved on the other end of the driving shaft 5, a pulley 8 is fixedly sleeved on the output shaft of the driving motor 3, the pulley 7 and the pulley 8 are sleeved on the same transmission belt 9 for transmission connection, a sealing plate 10 is fixedly installed on the end face of one side of the mounting frame 1 close to the pulley 7, and a plurality of curved air inlet pipes 11 are rotatably installed on the sealing plate 10; a plurality of adjusting blades 13 are movably installed on the end face of the other end of the mounting frame 1, and the angle of the adjusting blade 13 is adjusted by an angle adjustment mechanism.

[0034] The working principle of the present invention is:

[0035] First, when the intelligent monitoring and control equipment of the intelligent greenhouse (the existing equipment is not described in detail) detects that the carbon dioxide or oxygen concentration in the greenhouse is abnormal, the intelligent monitoring and control equipment controls the drive motor 3 to start, and the output shaft of the drive motor 3 is transmitted to the pulley 2 8, and the pulley 2 8 drives the pulley 7 to rotate through the transmission belt 9, so that the pulley 7 drives the drive shaft 5 to rotate, and then the drive shaft 5 is nested in the rotating mounting part 4 through the bearing and other structures to rotate and drive the blades 6, so that the blades 6 push the air, and then the external air enters the sealing plate 10 through the curved intake pipe 11, and then enters the installation frame 1, and then is pushed out from between the adjusting fan blades 13 by the blades 6.

[0036] In the present invention, outside air needs to enter the mounting frame 1 through the curved air intake pipe 11. Since the curved air intake pipe 11 has a shape, or is configured to prevent external raindrops from directly falling into the mounting frame 1, it avoids the situation in the invention patent with publication number CN118489467A where rainwater may fall directly into the greenhouse and then be blown into the greenhouse by the airflow. Then, since the airflow needs to be blown out from between the adjusting blades 13, the angle of the adjusting blades 13 can be adjusted by the angle adjustment mechanism, thereby achieving the adjustment of the wind direction.

[0037] In this embodiment, the curved air inlet pipe 11 is configured as a plastic hard pipe, and can actually be configured as a rubber hose. As long as the air inlet of the curved air inlet pipe 11 faces both sides when the greenhouse ventilation equipment is top-mounted, and faces downward when the greenhouse ventilation equipment is side-mounted, the rain shelter function can be achieved.

[0038] The present invention provides a specific solution of an angle adjustment mechanism: the angle adjustment mechanism comprises a mounting wall 16 fixed to the inner wall of a mounting frame 1, a plurality of rotation holes are provided on the mounting wall 16, both ends of the adjustment fan 13 are rotatably installed in the rotation holes through a rotating shaft 19, a control panel 21 is fixedly sleeved on the rotating shaft 19, a control button 20 is fixedly installed on one end of the control panel 21 away from the rotating shaft 19, a control motor 17 is fixedly installed at the bottom end of the mounting wall 16, a control vertical plate 18 is fixedly installed on the output shaft of the control motor 17, a plurality of transverse holes 22 are provided on the control vertical plate 18, and the transverse holes 22 are movably sleeved on the control button 20 in a one-to-one correspondence. The transverse holes 22 are strip holes, and the length of the strip holes is greater than twice the diameter of the control button 20.

[0039] When it is necessary to adjust the angle of the adjusting fan 13, that is, when the intelligent monitoring and control equipment detects that the concentrations of oxygen or carbon dioxide at multiple monitoring points in the greenhouse are quite different, the control driving control motor 17 is extended and retracted. When the control motor 17 is extended and retracted, the control vertical plate 18 fixedly connected thereto moves vertically accordingly, so that the horizontal hole 22 on the control vertical plate 18 will squeeze the control button 20 to move up and down, and the up and down movement of the control button 20 will be transmitted to the control board 21, and the control board 21 is fixedly connected to the rotating shaft 19, and the rotating shaft 19 is restricted to rotate in the rotating hole. Therefore, the control button 20 will drive the control board 21 to rotate, and then the control board 21 will drive the adjusting fan 13 to adjust the angle, and the length limit of the horizontal hole 22 is to reserve the lateral displacement caused by the rotation of the control button 20 when the control board 21 rotates a certain angle.

[0040] In this manner, only one control motor 17 is needed to adjust all the adjusting blades 13 , and the parallel arrangement of the adjusting blades 13 can be effectively utilized.

[0041] The mounting wall 16 can be a mounting platform extending from the inner wall of the mounting frame 1 , so that a cavity can be reserved between the two to leave space for placing structures such as the control riser 18 .

[0042] In the present invention, a plurality of mounting holes 12 are provided on the sealing plate 10, and a plurality of depressions are provided on the inner wall of each mounting hole 12. A mounting sleeve 14 is sleeved on the curved air intake pipe 11, and the mounting sleeve 14 is provided with protrusions corresponding to the depressions of the mounting holes 12. Specifically, when the number of the protrusions is set to 6, the mounting sleeve 14 can still be inserted after being rotated 60 degrees, which facilitates adjustment when alternating between side mounting and top mounting.

[0043] In the present invention, a sandwich is provided in the sealing plate 10, and a perforated adjustment plate 24 is slidably installed in the sandwich through a slide groove 23. A rack 25 is fixedly connected to the top of the perforated adjustment plate 24. A driving motor 26 is installed on the top of the sealing plate 10, and the driving motor 26 is meshed with the rack 25 through a gear 27. The opening 28 on the perforated adjustment plate 24 is a through hole and its size and position correspond to the mounting hole 12 one by one. A porous cushion layer is provided on the inner wall of the opening 28 on the perforated adjustment plate 24.

[0044] In rainy weather, even if raindrops can be prevented from dripping directly, the humidity of the air is still high. At this time, when the intelligent monitoring and control equipment detects that the humidity of the greenhouse air inlet is abnormal, the control driving motor 26 is turned on. When the driving motor 26 makes its output shaft rotate, the output shaft of the driving motor 26 is fixedly connected to the gear 27, and the gear 27 is rotatably mounted on the sealing plate 10, so the gear 27 can rotate with the output shaft of the driving motor 26, so that the gear 27 drives the gear rack 25 meshing therewith to slide linearly, so that the perforated adjustment plate 24 slides in the chute 23, and the opening 28 of the perforated adjustment plate 24 is staggered with the mounting hole 12, so that when the external air enters the staggered area of ​​the two, it is equivalent to forming a narrow tube effect, thereby accelerating the speed of the airflow. When the airflow flows rapidly, according to the Bernoulli principle, the flow rate of the fluid increases and the pressure decreases. In an airflow containing water vapor, this pressure change will cause the state of the water vapor to change. For example, in a high-speed airflow, the pressure on the water vapor molecules decreases. For saturated water vapor, the pressure reduction makes it easier to reach an oversaturated state. Once oversaturation is reached, the water vapor will be separated by condensation or deposition. Then, it is absorbed by a porous cushion layer (generally a water-absorbing material such as a sponge or cotton cloth). On the other hand, when the airflow encounters an obstacle or generates turbulence, the flow rate and flow direction will change, which will also affect the separation of water vapor. In some other embodiments, an impeller can also be rotatably installed in the opening 28 on the perforated adjustment plate 24 to further generate turbulence through the impeller.

[0045] Figure 8 The sealing plate 10 in the figure is cut from the middle part of the complete sealing plate 10 , and the purpose of providing the interlayer is to wrap a structure such as the driving motor 26 .

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
