Abstract
Description
Technical Field
[0001] This utility model relates to the field of semi-enclosed greenhouse technology, and in particular to a semi-enclosed greenhouse structure. Background Technology
[0002] In the planting area of a semi-enclosed greenhouse, it is necessary to exchange the air to facilitate the healthy growth of crops. Currently, climate channels are typically installed to regulate the climate within the planting area. These channels include outward-opening windows, evaporative cooling pads, surface coolers, axial flow fans, air ducts, and inward-opening windows, allowing for climate adjustment through self-circulation of gases within the greenhouse or exchange of gases between the inside and outside.
[0003] like Figure 1 and Figure 2 As shown, when adjusting the climate within the planting area through self-circulation of gases within the greenhouse, closing the outward-opening windows and opening the inward-opening windows and axial flow fans allows the greenhouse gases to pass through a surface cooler for cooling or heating before returning to the greenhouse planting area. Alternatively, when adjusting the climate through gas exchange between the inside and outside of the greenhouse, closing the inward-opening windows and opening the outward-opening windows and axial flow fans allows the outside gases to pass through the evaporative cooling pads and surface coolers for cooling or heating before entering the greenhouse planting area. When the air pressure in the greenhouse planting area is too high, the skylights will open to release the gases. Currently, the evaporative cooling pads are installed on the outer wall of the climate channel, exposed to direct sunlight, which affects their cooling and humidifying effects. Furthermore, during self-circulation of gases within the greenhouse, the gases cannot pass through the evaporative cooling pads for cooling or humidification, increasing the operating cost of the surface coolers. Improvements are needed in these areas. Utility Model Content
[0004] The purpose of this invention is to propose a semi-enclosed greenhouse structure that uses wet curtains for effective cooling and humidification, and can also cool or humidify the greenhouse when the gas inside the greenhouse is in self-circulation.
[0005] This utility model proposes a semi-enclosed greenhouse structure. The greenhouse structure includes a partition wall separating a climate channel and a planting area. Several ventilation openings are formed in the partition wall. The climate channel includes an airflow channel and a temperature regulation channel. The airflow channel consists of a first airflow zone and a second airflow zone that are interconnected. The first airflow zone is connected to the planting area through the ventilation openings. The temperature regulation channel is connected to the second airflow zone, and a wet curtain is installed at the connection point between the second airflow zone and the temperature regulation channel. A window connecting to the outside is opened on one side of the second airflow zone. This window has an inward-opening window that can block either the window or the first airflow zone. A surface cooler is installed in the temperature regulation channel. An exhaust device is installed between the temperature regulation channel and the planting area to extract gas from the temperature regulation channel into the planting area.
[0006] Preferably, the exhaust device includes an axial flow fan and an air duct. The air duct is installed in the planting area and one end is connected to the temperature control channel. The axial flow fan is located at the inlet of the air duct, and the surface cooler is located outside the inlet of the air duct.
[0007] Preferably, the airflow channel is inverted "L" shape, and the temperature regulation channel and the airflow channel are separated by a baffle wall. An installation opening is formed in the baffle wall, and the wet curtain is detachably installed at the installation opening.
[0008] Preferably, the mounting port is provided with fixing components on both sides. The fixing components include a fixing frame and a pair of fixing plates. The fixing frame is vertically fixed on the retaining wall, and the two fixing plates are fixed on the fixing frame. The side ends of the wet curtain are all embedded between the two fixing plates and abut against the surface of the fixing frame.
[0009] Preferably, the inward-opening window includes a window frame, a window sash, a drive motor, a transmission gear, and a transmission rack. The window frame is fixedly mounted on the window, one side of the window sash is hinged to the window frame, the drive motor is mounted on a retaining wall, the transmission gear is mounted on the shaft of the drive motor, and the transmission rack meshes with the transmission gear, with one end of it hinged to the other side of the window sash.
[0010] Preferably, a limiting member is provided on the barrier wall, the limiting member is located at the junction of the first airflow zone and the second airflow zone, and the window sash is flipped to abut against the surface of the limiting member.
[0011] Preferably, the duct opening is located at the bottom of the inner wall of the temperature regulating channel, and a partition is provided inside the temperature regulating channel. The partition is located above the wet curtain and the duct, and both sides abut against the side wall of the temperature regulating channel.
[0012] Preferably, the partition is inclined, and the horizontal position of the partition near the air duct is lower than the horizontal position of the partition near the wet curtain, so that the gas passing through the wet curtain can flow along the partition to the surface cooler.
[0013] Preferably, a skylight is provided at the top of the planting area.
[0014] As can be seen from the above description of this utility model, this utility model has the following beneficial effects:
[0015] 1. In this semi-enclosed greenhouse structure, the wet curtain is placed between the airflow channel and the temperature regulation channel. Therefore, the wet curtain is not exposed to direct sunlight, which makes the wet curtain have better cooling and humidification performance. Moreover, the location of the wet curtain means that when the gas in the greenhouse is self-circulating, the gas can also be cooled or humidified through the wet curtain.
[0016] 2. The climate channel of this semi-enclosed greenhouse structure only needs to be equipped with an inward-opening window. The window sash of the inward-opening window is controlled by a drive motor to rotate, so that the window sash can switch back and forth between blocking the window and blocking the first airflow zone, saving the installation of an outward-opening window and thus reducing the construction cost of the climate channel.

[0026] To make the technical problem to be solved, the technical solution and the beneficial effects of this utility model clearer and more understandable, the following description is provided in conjunction with the appendix. Figure 3-8The present invention will be further described in detail below with reference to the embodiments. It should be understood that the specific embodiments described herein are only for explaining the present invention and are not intended to limit the present invention.
[0027] Reference Figure 3 , Figure 4 and Figure 5 A semi-enclosed greenhouse structure includes a partition wall 9 that separates the greenhouse into a climate channel 1 and a planting area 2. Several ventilation openings 91 are formed on the partition wall 9. The climate channel 1 is located on one side of the planting area 2 and is used to change the temperature and humidity environment within the planting area 2. The climate channel 1 includes an airflow channel 3 and a temperature regulation channel 4, which are separated by a baffle wall 33 within the climate channel 1. The airflow channel 3 is inverted "L" shape and consists of a first airflow zone 31 and a second airflow zone 32 that are interconnected. One end of the first airflow zone 31 is connected to the planting area 2 through the ventilation openings 91 on the partition wall 9, and the side of the second airflow zone 32 facing the planting area 2 is connected to the temperature regulation channel 4. An exhaust device 7 is installed between the temperature regulation channel 4 and the planting area 2 to extract gas entering the temperature regulation channel 4 into the planting area 2, thus creating an internal gas circulation within the greenhouse at the planting area 2, the airflow channel 3, and the temperature regulation channel 4.
[0028] Reference Figure 3 , Figure 4 and Figure 5 A wet curtain 5 is installed at the flow point between the second airflow zone 32 and the temperature control channel 4. An installation opening 331 (not shown in the figure) is formed between the baffle wall 33 between the airflow channel 3 and the temperature control channel 4, and the wet curtain 5 is installed at the installation opening 331. Fixing members 41 are provided on both sides of the installation opening 331. Each fixing member 41 includes a fixing frame 441 and a pair of fixing plates 412. The fixing frame 441 is vertically fixed to the baffle wall 33, and both fixing plates 412 are fixed to the fixing frame 441, making them perpendicular to each other. The side end of the wet curtain 5 is inserted between the two fixing plates 412, abutting against the surface of the fixing frame 441. The wet curtain 5 is installed at the installation opening 331 of the baffle wall 33 through the fixing members 41, thus ensuring a secure installation and easy disassembly and replacement of the wet curtain 5. The wet curtain 5 is placed between the airflow channel 3 and the temperature regulation channel 4, so the wet curtain 5 is not exposed to direct sunlight, which makes the wet curtain 5 have better cooling and humidification performance; and the location of the wet curtain 5 means that when the gas in the greenhouse is self-circulating, the gas can also be cooled or humidified through the wet curtain 5.
[0029] The exhaust system 7 includes an axial flow fan 71 and an air duct 72. The air duct 72 is installed inside the planting area 2, with one end connected to the bottom of the side wall of the temperature control channel 4. The axial flow fan 71 is positioned at the inlet of the air duct 72. A surface cooler 6 is installed inside the temperature control channel 4, located outside the inlet of the air duct 72. When the axial flow fan 71 starts, the gas exhausted from the planting area 2 into the airflow channel 3 passes through the wet curtain 5 and enters the temperature control channel 4. The gas cools and humidifies after passing through the wet curtain 5. After being cooled by the surface cooler 6, the gas enters the air duct 72 under the action of the axial flow fan 71, thus returning the gas to the planting area 2 and achieving gas self-circulation within the greenhouse.
[0030] Reference Figure 3 , Figure 6 and Figure 7 To facilitate gas exchange between the inside and outside of the greenhouse, a window 34 is formed on one side of the second airflow zone 32 of the airflow channel 3. An inward-opening window 8 is installed at the window 34. The inward-opening window 8 includes a window frame 81, a window sash 82, a drive motor 83, a transmission gear 84, and a transmission rack 85. The window frame 81 is fixedly mounted on the window 34, and one side of the window sash 82 is hinged to the window frame 81. The drive motor 83 is fixedly mounted on the retaining wall 33, and the transmission gear 84 is fixedly mounted on the shaft of the drive motor 83. One end of the transmission rack 85 is hinged to the other side of the window sash 82. Thus, the shaft of the drive motor 83 rotates, causing the transmission gear 84 to drive the transmission rack 85, thereby rotating the window sash 82. This allows the window sash 82 to switch back and forth between blocking the window 34 and blocking the first airflow zone 31. When window sash 82 blocks window 34, it enables self-circulation of gas within the greenhouse. When window sash 82 blocks the first airflow zone 31, it enables gas exchange between the inside and outside of the greenhouse. Additionally, a limiting component 35 is installed on the baffle wall 33. Driven by the transmission rack 85, window sash 82 rotates until it abuts against the limiting component 35. This abutment between window sash 82 and the limiting component 35 provides a better seal for the first airflow zone 31, preventing gas from flowing into the second airflow zone 32 through the gap between window sash 82 and baffle wall 33. This eliminates the need for an outward-opening window in the climate passage 1, reducing its construction cost.
[0031] When the climate channel 1 is used for gas exchange between the inside and outside of the greenhouse, in order to avoid excessive air pressure in the greenhouse planting area 2, a skylight 21 (not shown in the figure) is opened at the top of the indoor area 2. When the window sash 82 blocks the first airflow zone 31, outdoor air enters the second airflow zone 32 through the window 34. At the same time, the axial flow fan 71 starts working, allowing the air entering the second airflow zone 32 from the outside to pass through the wet curtain 5 and enter the temperature control channel 4, thereby achieving the purpose of cooling and humidification. Subsequently, the air in the temperature control channel 4 is cooled by the surface cooler 6 and then enters the air duct 72 under the action of the axial flow fan 71, thus allowing the air to enter the planting area 2. At the same time, the skylight 21 in the planting area 2 is in the open state to release the air in the planting area 2, thereby maintaining a suitable air pressure state in the planting area 2.
[0032] After the gas enters the temperature regulating channel 4, a baffle 42 is installed inside the temperature regulating channel 4 to facilitate its complete entry into the air duct 72 under the action of the axial flow fan 71, thereby preventing gas accumulation at the top of the temperature regulating channel 4. The baffle 42 is located above the wet curtain 5 and the air duct 72, and both sides of the baffle 42 abut against the inner wall of the temperature regulating channel 4. The horizontal position of the baffle 42 near the air duct 72 is lower than the horizontal position of the baffle 42 near the wet curtain 5. This allows the gas entering the temperature regulating channel 4 to flow along the surface of the baffle 42 to the surface cooler 6, and also facilitates the gas's entry into the air duct 72 under the action of the axial flow fan 71.
[0033] The specific implementation principle of this application embodiment is as follows: When the semi-enclosed greenhouse structure requires gas self-circulation, the window sash 82 blocks the window 34. The axial flow fan 71 starts working, and the gas in the planting area 2 is discharged from the ventilation opening 91 of the partition wall 9, and flows sequentially through the first airflow zone 31 and the second airflow zone 32, and passes through the wet curtain 5 to enter the temperature regulation channel 4. After passing through the wet curtain 5 to achieve the purpose of cooling and humidification, the gas flows along the bottom surface of the partition 42 to the surface cooler 6, where the gas is cooled again. Finally, under the action of the axial flow fan 71, the gas is drawn into the air duct 72, thereby allowing the gas to circulate back into the planting area 2, thus realizing gas self-circulation in the greenhouse.
[0034] When gas exchange between the inside and outside of the greenhouse is required in the climate channel 1, the shaft of the drive motor 83 rotates, thereby driving the transmission gear 84 to rotate. This causes the window sash 82 to flip upwards under the action of the transmission gear 84 and the transmission rack 85 until it abuts against the bottom surface of the limiting member 35, thus blocking the first airflow zone 31. At this time, outdoor gas enters the second airflow zone 32 through the window 34, passes through the wet curtain 5, and enters the temperature control channel 4. After passing through the wet curtain 5 to achieve cooling and humidification, the gas flows along the bottom surface of the partition 42 to the surface cooler 6, where it is cooled again. Finally, under the action of the axial flow fan 71, the gas is drawn into the air duct 72, so that the gas is recirculated into the planting area 2. At the same time, the skylight 21 at the top of the planting area 2 is open, so that the hot air in the planting area 2 can be discharged from the skylight 21, so that the air pressure in the planting area 2 is in a suitable state, thereby facilitating the exchange of gases between the inside and outside of the greenhouse in the climate channel 1.
[0035] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution to other situations without modification, shall be protected by the present invention.
