Description

Greenhouse covering device combination mechanism Technical Field

[0001] The present invention relates to the technical field of greenhouses, and in particular to a greenhouse covering device assembly mechanism capable of adjusting greenhouse ventilation or covering according to environmental requirements. Background Art

[0002] To combat the volatile weather and prevent pests and diseases, greenhouses are often used to grow crops. However, because greenhouses are relatively enclosed spaces, temperatures can rise significantly during high summer temperatures, affecting crop growth. High temperatures are also detrimental to working in greenhouses. Therefore, greenhouses are often equipped with ventilation and heat dissipation mechanisms.

[0003] For example, the greenhouses disclosed in Taiwan Patents TWM478336 and TWM445845 have upright skylights and vents on one side of the roof. Furthermore, a covering is provided over the vents that can be retracted when the external temperature is high to allow ventilation through the vents. Furthermore, the covering can be unfolded to cover the vents when it rains or is cold to prevent rain or cold wind from entering the greenhouse.

[0004] However, the aforementioned vents occupy only a small area of ​​the greenhouse roof, resulting in poor ventilation and heat dissipation efficiency. Furthermore, the vertical vents are complex, requiring modifications to the greenhouse roof shape, and are located high up in the greenhouse, making maintenance difficult. Furthermore, during headwinds, strong external winds flow directly back into the vents, preventing the heat from rising and being discharged through the vents. Furthermore, during typhoons, strong winds directly impact the outwardly projecting vertical skylights, resulting in poor wind resistance.

[0005] Taiwan Patent TWM508201 discloses a greenhouse comprising an inner and outer roof frame. The inner roof frame is provided with a retractable or deployable shielding layer. The outer roof frame is positioned above the inner roof frame and is provided with a fine mesh layer. The inner roof frame's shielding layer can be controlled to prevent rain or cold air from entering the greenhouse, while the retractable shielding layer can allow heat to escape. Furthermore, the outer roof frame's fine mesh layer prevents insects from entering the greenhouse and harming crops.

[0006] However, the aforementioned structure requires the provision of an inner top frame and an outer top frame, which results in high manufacturing costs, and causes the columns of the greenhouse to simultaneously support the weight of the inner and outer top frames, resulting in a defect of poor support stability.

[0007] Summary of the Invention

[0008] The object of the present invention is to provide a mechanism which is easy to install and control, can adjust the ventilation or covering of a greenhouse, and has better heat dissipation effect and wind pressure resistance.

[0009] The covering device of the greenhouse covering device combination mechanism of the present invention is arranged above the greenhouse, and includes: an upper covering body, the area of ​​which is larger than the area of ​​the top of the greenhouse, covering the top of the greenhouse, having a mesh part and a covering part, the mesh part having breathable mesh holes, and the covering part connected to the mesh part, and the air permeability of the covering part is lower than that of the mesh part; two shafts, respectively pivotally arranged on both sides above the greenhouse, the two shafts respectively engaged with the two ends of the upper covering body; at least one control device, linked to the shaft, and capable of driving the shaft to rotate to cause the upper covering body to move.

[0010] Furthermore, the two shafts are arranged corresponding to the front and rear directions of the greenhouse, and the net part is arranged corresponding to the front and rear directions of the greenhouse; the covering part is arranged corresponding to the front and rear directions of the greenhouse, and one side of the covering part is connected to the adjacent side of the net part.

[0011] Furthermore, the covering part material is agricultural film or plastic sheeting.

[0012] Furthermore, the greenhouse has a plurality of vertical columns on the ground, and a connecting frame, a drainage trough, and a top frame are arranged above the columns; the drainage trough is arranged on the side of the top frame corresponding to the front and rear directions of the greenhouse, and pivot seats that can engage the shaft rod are arranged on both sides of the top frame.

[0013] Furthermore, the covering body is arranged above the top frame.

[0014] Furthermore, the mesh part and the covering part of the upper covering body are overlapped, combined and fixed, the area of ​​the mesh part is larger than the area of ​​the covering part, and the covering part covers part of the mesh part, and the uncovered area forms a breathable part, and the two ends of the mesh part are respectively connected to the two shafts.

[0015] Furthermore, the mesh part and the covering part of the upper covering body have corresponding areas and are overlapped, assembled and fixedly connected; and the covering part is provided with a hollow area.

[0016] Furthermore, the control device has two, and each of the control devices is linked to one of the shafts.

[0017] Furthermore, the control device has a motor.

[0018] Furthermore, the control device receives external signals to automatically control the action, and the signal sources include: detection devices for detecting rain, strong wind, temperature, and the network.

[0019] After adopting the above technical solution, the present invention has at least the following effects.

[0020] 1. In hot weather, the present invention allows the control device to rotate the shaft so that the mesh portion of the upper covering body is positioned above the greenhouse. Because the mesh portion can be provided with a larger area than conventional skylights and vents, hot air inside the greenhouse can quickly rise and be discharged through the mesh portion. External air can also enter the greenhouse through the mesh portion, thereby achieving better heat dissipation efficiency for cooling the greenhouse. In addition, because the upper part of the greenhouse is still shielded by the mesh portion, insects and birds from outside can be prevented from entering the greenhouse and harming crops.

[0021] 2. In the event of rain, typhoons, or cold weather, the present invention can rotate the shaft by a control device, and position the covering portion above the greenhouse. This prevents the heat inside the greenhouse from escaping from above, and prevents rain and strong winds from entering the greenhouse from above. Furthermore, because the covering portion of the present invention fits closely to the top of the greenhouse, it has better wind resistance and will not cause the upper covering body to be blown off by strong winds, thereby providing better wind resistance and stability.

[0022] 3. The structure of the present invention is relatively simple. The upper covering body and the shaft rod can be installed before leaving the greenhouse and then installed together on the top of the greenhouse, which is easier to install.

[0023] 4. The present invention can adjust the heat dissipation and ventilation conditions of the greenhouse to suit environmental requirements simply by controlling the rotation of the shaft with the aid of a control device, making it easier to control.

[0024] 5. During cleaning and maintenance of the present invention, the user can be located at a walkable drainage trough above the greenhouse, and can activate the control device to rotate the shaft so that the mesh part or covered part to be cleaned and maintained is located near the drainage trough, which can provide better cleaning and maintenance convenience and safety.

[0025] 6. When the mesh part and the covering part are stacked and fixed together, they can have better wind pressure resistance and make the shaft rod retracting the covering body smoother, thereby improving the stability of the shaft rod retraction.

[0026] 7. When the control device controls the shaft to retract the upper covering body by receiving external signals such as detection devices for detecting rain, strong wind, temperature, and the network, human resources can be saved and the level of automation can be improved.

[0038] DETAILED DESCRIPTION

[0039] In the following embodiments, similar functional components of the present invention are denoted by the same reference numerals. FIGURES 1 and 2 illustrate the first embodiment of the present invention. A covering device 2 is mounted above a greenhouse 1. The greenhouse 1 comprises a plurality of vertical columns 11, each vertically mounted on the ground. A coupling frame 12, a drainage trough 13, and a top frame 14 are mounted above the columns 11. A lower covering body 111 and a door 112 are mounted to the sides of the columns 11. Side covering bodies 141 are mounted on the front and rear sides of the top frame 14. In this embodiment, the top frame 14 is semicircular in shape; in other embodiments, the top frame 14 may have other shapes. The drainage trough 13 is positioned on the left and right sides of the top frame 14, corresponding to the front and rear directions of the greenhouse 1. Pivots 15 are mounted on both sides of the top frame 14, located at the front and rear ends of the sides. For a longer greenhouse 1, more than two pivots 15 may be mounted on the sides of the top frame 14, each supporting more than two covering devices 2.

[0040] The covering device 2 comprises an upper covering body 21, two shafts 22, and two control devices 23. The upper covering body 21 has an area larger than the top area of ​​the greenhouse 1 and comprises a mesh portion 211 and a covering portion 212. The mesh portion 211 is disposed in the front and rear directions of the greenhouse 1 and has air-permeable mesh holes. In this embodiment, the area of ​​the mesh portion 211 is larger than the top area of ​​the greenhouse 1. The covering portion 212 is disposed in the front and rear directions of the greenhouse 1, with one side connected to an adjacent side of the mesh portion 211. The covering portion 212 can be made of agricultural film, plastic sheeting, or other low-permeability materials, which have much lower air permeability than the mesh portion 211. In this embodiment, the covering portion 212 has an area larger than the top area of ​​the greenhouse 1.

[0041] The two shafts 22 are pivotally mounted on the pivot seats 15 on both sides of the upper part of the greenhouse 1 in the front and rear directions respectively. The two shafts 22 are respectively engaged with the two ends of the upper covering body 21, and the shafts 22 can retract a portion of the upper covering body 21, and the upper covering body 21 can be covered on the top frame 41.

[0042] The control device 23 is linked to the shaft 22 and can drive the shaft 22 to rotate. The control device 23 can include a motor to electrically control the rotation of the shaft 22 or a handle (not shown) to manually control the rotation of the shaft. The control device can be connected to a detection device (not shown) that can detect rain, strong winds, and temperature to automatically control the motor's operation. The control device can also be connected to a network for remote control. The present invention can also be provided with a control device connected to both shafts 22 (not shown) to switch the control of the movement of one shaft 22.

[0043] Referring to Figures 1 and 3, in hot weather, the control device 23 of the present invention can rotate the shaft 22 to position the mesh portion 211 of the upper covering body 21 above the greenhouse 1. Since the mesh portion 211 can be provided with a larger area than conventional skylights and vents, the hot air inside the greenhouse 1 can quickly rise and be discharged through the mesh portion 211. At the same time, external air can also enter the greenhouse 1 through the mesh portion 211 to cool the greenhouse 1. At this time, because the upper part of the greenhouse 1 is still shielded by the mesh portion 211, it can prevent external insects and birds from entering the greenhouse 1 and harming the crops.

[0044] Referring to Figures 1 and 4 , the present invention utilizes a control device 23 to rotate shaft 22 during rain, typhoons, or cold weather, positioning cover 212 above greenhouse 1. The control device 23 includes a motor and, when connected to a detection device, can sense rain, wind, or temperature changes. The detection device can actively rotate the right shaft 22 and passively rotate the left shaft 22, allowing cover 212 to be smoothly positioned above greenhouse 1. This facilitates operation. Furthermore, when the control device is electrically connected to the internet, the user can remotely control the motor, providing remote control. Furthermore, the top surface of cover 212 can be provided with a reflective surface. Therefore, if solar panels (not shown) are installed above greenhouse 1, light can be reflected from the cover 212 to the panels, thereby improving power generation efficiency.

[0045] The upper portion of the greenhouse 1 of the present invention is covered by the covering portion 212 of the upper covering body 21, thereby preventing the temperature in the greenhouse 1 from escaping from the upper portion of the greenhouse 1 and preventing rain and strong winds from entering the greenhouse 1 from the upper portion of the greenhouse 1. Since the covering portion 212 of the present invention fits the roof frame 14 of the greenhouse 1, it has better wind resistance and will not cause the upper covering body 21 to be blown up by strong winds, thereby having better wind resistance stability. When the rain stops or the wind decreases and the temperature increases, the control device 23 can cause the left shaft 22 to actively rotate in the opposite direction as shown in Figure 3, and the mesh portion 211 can be moved to a position above the greenhouse 1 to provide ventilation and heat dissipation functions.

[0046] When the upper covering body 21 of the present invention needs to be cleaned and maintained, the user can be located at the drainage trough 13 above the greenhouse 1 where walking is possible, and the control device 23 can be activated to rotate the shaft 22 so that the mesh part 211 or the covering part 212 to be cleaned and maintained is located near the drainage trough 13, which can provide better cleaning and maintenance convenience and safety.

[0047] Please refer to Figure 5 which is a second embodiment of the present invention. The second embodiment is similar to the first embodiment, with the difference that the area of ​​the mesh portion 211 of the covering device 2 of the present invention is smaller than the top area of ​​the greenhouse 1, and the mesh portion 211 can be controlled to be located above the center of the greenhouse 1 to facilitate heat dissipation. The upper positions on both sides of the greenhouse 1 are the covering portions 212 so that both sides of the greenhouse 1 have a covering function.

[0048] Please refer to Figures 6 and 7 for a third embodiment of the present invention. This third embodiment is similar to the first embodiment, except that the mesh portion 211 and the covering portion 212 of the upper covering body 21 are formed as a stacked lower and upper assembly. The mesh portion 211 is larger than the covering portion 212, and the covering portion 212 is bonded to a portion of the mesh portion 211 by gluing, sewing, or other appropriate means, forming a breathable portion in the uncovered area 213. The mesh portion 211 is bonded to two shafts 22 at each end. Because the upper covering body 21 has a complete, uninterrupted mesh portion 211, the rotation of the shafts 22 can more smoothly drive the displacement of the upper covering body 21, resulting in greater operational stability. Furthermore, the covering portion 212 is reinforced by the mesh portion 211, providing greater strength.

[0049] In this embodiment, when the uncovered area 213 of the upper covering body 21 is located above the greenhouse, the ventilation and heat dissipation function of the greenhouse can be improved. The mesh portion 211 can prevent insects and birds from entering the greenhouse. The shaft 22 can be rotated so that the covering portion 212 can be located above the greenhouse and can provide a covering effect for the greenhouse. The reinforced covering portion 212 can also have better wind pressure resistance.

[0050] FIG8 and FIG9 illustrate a fourth embodiment of the present invention. This fourth embodiment is similar to the first embodiment, except that the mesh portion 211 and the covering portion 212 of the upper cover 21 correspond in area and are stacked and fixedly connected. A shaft 22 is attached to each end, and a perforated area 214 is cut into a portion of the covering portion 212, so that only the air-permeable mesh portion 211 is located within the perforated area 214. Consequently, when the perforated area 214 is positioned above the greenhouse, it provides improved heat dissipation, and the mesh portion 211 prevents insects and birds from entering the greenhouse 1. Furthermore, when the perforated area 214 is retracted and not positioned above the greenhouse, it is covered by the covering portion 212, preventing wind and rain from entering the greenhouse 1. Furthermore, the mesh portion 211 and the covering portion 212 are not cut off to correspond to the length of the upper cover 21, which facilitates smoother and more stable retraction of the shaft 22. Furthermore, the covering portion 212 is combined and reinforced by the mesh portion 211 , thereby improving the strength and wind resistance of the upper covering body 21 .

[0051] Therefore, as described above, the covering device of the present invention is easy to install above the greenhouse and can be easily adjusted to achieve better heat dissipation or better shielding and wind pressure resistance over a large area. The aforementioned embodiments are illustrative of the present invention and are not limiting of the present invention. Any equivalent changes based on the spirit of the present invention should also fall within the scope of the present invention.
