Description

Technical Field

[0001] The present application relates to the field of greenhouse technology, and in particular to a greenhouse cooling device. Background Art

[0002] A greenhouse is a building that controls or partially controls the plant growth environment. It's often used for non-seasonal or non-regional plant cultivation, scientific research, multi-generational breeding, and ornamental plant cultivation. Controlling the plant growth environment primarily involves controlling conditions such as temperature, humidity, and light. However, high greenhouse temperatures in the summer can affect plant growth. To address this, existing technologies often use fans or wet curtains to cool greenhouses. However, fans are slow and ineffective, while wet curtains can increase indoor humidity while reducing temperatures. Improvements are needed. Utility Model Content

[0003] In order to address the above-mentioned deficiencies in the prior art, the present application provides a greenhouse cooling device that can enhance the cooling effect while preventing excessive changes in the humidity in the greenhouse.

[0004] In order to achieve the above purpose, the utility model adopts the following technologies:

[0005] A greenhouse cooling device includes a fan with a water curtain assembly on one side and a first frame between the fan and the water curtain assembly. During installation, the fan is embedded in the side wall of the greenhouse and the water curtain assembly is located outside the greenhouse.

[0006] The water curtain assembly includes multiple guide plates arranged at intervals, and the direction of the gaps formed by the intervals is consistent with the direction of the airflow formed by the fan. The guide plates are arranged in the vertical direction. A number of drainage holes are provided above the corresponding guide plates of the water curtain assembly, and a water receiving trough is provided below the corresponding guide plates of the water curtain assembly. The water curtain assembly is also provided with a water pump to supply water to the drainage holes.

[0007] A plurality of dehumidification plates are arranged in an array at intervals along the height direction inside the first frame. The dehumidification plates are arranged horizontally. The same side of the dehumidification plates is rotatably connected to the first frame. The distance between adjacent dehumidification plates is less than or equal to the width of the dehumidification plates.

[0008] The beneficial effect of the utility model is that the greenhouse cooling device cools the air near the device outside the greenhouse by setting a water curtain assembly, and then prevents the application of the water curtain assembly from affecting the mature humidity conditions formed in the greenhouse by rotating the dehumidification plate set inside the first frame. Finally, the setting of the fan allows the outside air to enter the greenhouse after being cooled by the water curtain assembly, and exchange heat with the hot air in the greenhouse again, thereby achieving the purpose of cooling the greenhouse. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] The drawings described herein are for illustrative purposes only of selected embodiments and not all possible implementations, and are not intended to limit the scope of the present invention.

[0010] Figure 1 It is an installation diagram of an embodiment of the present application.

[0011] Figure 2 It is an exploded view of an embodiment of the present application.

[0012] Figure 3 yes Figure 2 A partial enlarged view of point A in the middle. DETAILED DESCRIPTION

[0013] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the implementation methods of the present invention are described in detail below with reference to the accompanying drawings. However, the embodiments described in the present invention are only part of the embodiments of the present invention, rather than all the embodiments.

[0014] The embodiment of the present application provides a greenhouse cooling device, such as Figure 1 and Figure 2 As shown, it includes a fan 1, a water curtain assembly 2 is provided on one side of the fan 1, and a first frame 3 is provided between the fan 1 and the water curtain assembly 2. During installation, the fan 1 is embedded in the side wall of the greenhouse, and the water curtain assembly 2 is located outside the greenhouse.

[0015] The water curtain assembly 2 includes a plurality of guide plates 21 arranged at intervals, and the direction of the gaps formed by the intervals is consistent with the direction of the airflow formed by the fan 1. The guide plates 21 are arranged in the vertical direction. A plurality of drainage holes are provided above the guide plates 21 corresponding to the water curtain assembly 2, which are used to transport water to the guide plates 21 below. A water receiving trough 22 is provided below the guide plates 21 corresponding to the water curtain assembly 2. The water curtain assembly 2 is also provided with a water pump 4 for supplying water to the drainage holes.

[0016] Inside the first frame 3, a plurality of dehumidification plates 31 are arranged in an array along the height direction at intervals. The dehumidification plates 31 are made of a highly absorbent resin, such as starch grafted acrylates and grafted acrylamide. The dehumidification plates 31 are arranged horizontally, and the same side of the dehumidification plates 31 is rotatably connected to the first frame 3 to facilitate the vertical adjustment of the airflow direction entering the fan 1. The distance between adjacent dehumidification plates 31 is less than or equal to the width of the dehumidification plates 31. The interior of the first frame 3 can be sealed by rotating the dehumidification plates 31. This method can not only block sunlight, but also prevent rainwater from entering the fan 1 and the interior of the greenhouse through the first frame 3 during thunderstorms.

[0017] When in use, start the water pump 4, and the water flowing out of the water pump 4 flows out through the drainage hole to the guide plate 21. Since the temperature of the water flowing on the guide plate 21 is lower than the temperature of the air near the water curtain assembly 2, the water absorbs heat and the air releases heat, which in turn causes the temperature of the nearby air to drop. At this time or before, start the fan 1 to cause air convection between the high-temperature air in the room and the outdoor air. The cooled outdoor air enters the room, and the high-temperature air in the room flows to the outside, which initially reduces the temperature in the greenhouse.

[0018] After the cooled air enters the room, it exchanges heat with the hot air inside the room again, further lowering the temperature inside the greenhouse.

[0019] During this process, the angle of the dehumidification plate 31 can be adjusted according to the humidity in the greenhouse. For example, if the humidity in the greenhouse is too high, adjusting the angle of the dehumidification plate 31 can increase the contact area between the dehumidification plate 31 and water molecules, thereby adsorbing the water molecules and achieving a dehumidification effect.

[0020] Specifically, such as Figure 2 As shown, a second frame 5 is provided on the side of the fan 1 facing the greenhouse, and a plurality of wind guide plates 51 are arranged in a vertical or horizontal direction in the second frame 5. The same side of the wind guide plates 51 is rotatably connected to the second frame 5. By adjusting the angle of the wind guide plates 51, the direction of air supply into the greenhouse can be controlled, the air supply range can be expanded, and the heat exchange efficiency of the air in the greenhouse can be improved.

[0021] Specifically, such as Figure 2 As shown, the second frame 5 and the first frame 3 are both provided with driving mechanisms for controlling the rotation of the air guide plate 51 and the dehumidification plate 31 respectively.

[0022] Specifically, such as Figure 2 and Figure 3 As shown, the driving mechanism of the second frame 5 includes a motor 52 provided on the top or side of the second frame 5. A first connecting rod 53 is fixedly sleeved on the output shaft of the motor 52 and connected to one end of the first connecting rod 53. A rotating plate 54 is rotatably provided on the other end of the first connecting rod 53. One end of the rotating shaft of the air guide plate 51 passes through the outer wall of the second frame 5. The portion of the rotating shaft extending from the second frame 5 is fixedly sleeved with a second connecting rod 55 and connected to one end of the second connecting rod 55. The other end of the second connecting rod 55 is rotatably connected to a push rod 56. The top of the push rod 56 is rotatably connected to the other end of the rotating plate 54. The driving mechanism of the first frame 3 can also adopt this structural principle, which will not be described in detail here.

[0023] Specifically, such as Figure 2As shown, a horizontally arranged pipe groove 23 is provided above the guide plate 21, and a drainage hole 22 is provided at the bottom of the pipe groove 23. A plurality of drainage holes 22 are provided along the length of the pipe groove 23 to cover all the guide plates 21. As another preferred structure, the outlet pipe of the water pump 4 can be horizontally arranged above the guide plate 21, and a drainage hole can be provided at the bottom of the outlet pipe of the water pump 4.

[0024] Specifically, such as Figure 1 and Figure 2 As shown, the water inlet pipe of the water pump 4 is connected to a water reservoir 6. The water receiving tank 22 is provided with a drain pipe 24, which is connected to the water reservoir 6 to realize water circulation, save costs and improve the efficiency of the device. As an option, the water reservoir 6 can be set underground, and the temperature of the underground can be used to cool the water in the water reservoir 6.

[0025] Preferably, the guide plate 21 has a wavy structure, which increases the residence time of the water flow on the guide plate 21, thereby transferring more cold air into the room to improve the cooling effect.

[0026] Preferably, meshes are provided on the guide plate 21 to further prolong the residence time of the water flow on the guide plate 21 and further disperse the water flow, thereby improving the cooling effect.

[0027] In application, the above description is only a preferred embodiment of the present application and is not intended to limit the present application. Obviously, those skilled in the art can make various changes and modifications to the present application without departing from the spirit and scope of the present application.
