Description

Technical Field

[0001] This utility model relates to the technical field of automatic opening and closing temperature control and regulation devices, and in particular to an automatic opening and closing temperature control and regulation device for the ventilation openings of a kiwi fruit isolation shed. Background Technology

[0002] A kiwifruit isolation greenhouse is a facility specifically designed for the cultivation and protection of kiwifruit. It prevents the invasion of external pests and diseases, reduces pesticide use, and thus improves the safety and quality of kiwifruit. The greenhouse controls internal environmental conditions such as temperature, humidity, and light, providing the most suitable growing environment for kiwifruit, which helps increase yield and quality.

[0003] To ensure a suitable environment inside the isolation shed, ventilation components are added to aid air circulation. For example, Chinese Patent Publication No. CN214413640U provides a kiwifruit rootstock seedling cultivation shed, belonging to the field of agricultural nursery cultivation auxiliary devices. Its structure specifically consists of a detachable water trough, a cultivation trough, an isolation net, and a supporting frame, connected from bottom to top. A transparent film is installed on the supporting frame. The cultivation trough has multiple parallel strip-shaped holes at its bottom, and the water trough is connected to a water inlet pipe for injecting water into it. This utility model adopts a modular, detachable structure for rapid assembly during use. Depending on actual needs, one or more units can be assembled, achieving a cultivation area of ​​several to hundreds of square meters, specifically addressing the inconvenience of small-scale nursery cultivation.

[0004] Currently, after the ventilation components are installed in the isolation shed, ventilation and air-blocking operations need to be carried out according to the actual situation. In addition, during the ventilation process, the temperature of the airflow needs to be adjusted according to the temperature of the external environment to avoid the continuous airflow between the airflow and the air inside the isolation shed in high or low temperature environments, which could cause an imbalance in the constant temperature environment for kiwi fruit growth. Utility Model Content

[0005] The purpose of this utility model is to address the aforementioned shortcomings in the existing technology by proposing an automatic opening and closing temperature control device for the ventilation openings of a kiwi fruit isolation shed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design an automatic opening and closing temperature control device for the ventilation opening of a kiwi fruit isolation shed, including a channel one, a processor fixedly installed at the lower end of the channel one, and a temperature probe fixedly installed at the lower end of the processor's housing;

[0008] One side of the channel is fixed with bushings at both the top and bottom ends. A shaft is rotatably installed inside the two bushings. A motor is fixedly installed at the lower end of the channel by a bracket. A rotating shaft for driving is provided inside the motor. The end of the rotating shaft is fixedly connected to the shaft by a coupling. A sealing plate for rotating opening and closing is fixedly wrapped on the surface of the shaft inside the channel. The edge of the sealing plate is tightly attached to the inner wall of the channel.

[0009] A second motor is fixedly installed on the inner wall of the first channel by a bracket. The second motor has a rotating shaft for driving inside, and the end of the rotating shaft is fixedly connected to a shaft rod by a coupling. Several blades are fixedly distributed on the surface of the shaft rod.

[0010] Preferably, one end of the first channel is provided with a second channel, and the other end of the second channel is closely attached to the main air duct.

[0011] Preferably, a number of ceramic seats are fixedly installed on the upper end of the inner wall of the second channel, and a ceramic sleeve corresponding to the position of the ceramic seat is also fixedly installed through the lower end of the inner wall of the main air duct.

[0012] Preferably, an electric heating tube is inserted and fixed inside the ceramic base, the electric heating tube extends downward through the ceramic sleeve, and multiple layers of fins are fixedly distributed on the surface of several electric heating tubes along the vertical position.

[0013] Preferably, a curved tube is also provided through the inner wall of the second channel, and multiple layers of fins are fixed on the surface of the curved tube along the upper and lower positions.

[0014] Preferably, both ends of the bend extend downward through the inner wall of the second channel, with a cold water inlet at one end and a cold water outlet at the other end.

[0015] Preferably, threaded columns are fixedly installed on both sides of the outer wall of the second channel by brackets, and collars are fixedly installed on both sides of the first channel and the main air duct, with the surface of the threaded column and the inside of the collar slidingly connected.

[0016] Preferably, a threaded cap is threaded onto the end of the threaded column, and one end of the threaded cap is tightly fitted against the end face of the collar.

[0017] The design scheme proposed in this utility model has the following beneficial effects in application:

[0018] 1. This solution monitors the external ambient temperature in real time using a temperature probe and automatically adjusts the opening and closing of the ventilation openings and the airflow temperature in conjunction with the processor. When the temperature is low, the system shuts off the cold water supply and starts the electric heating tube to heat the airflow, preventing cold air from directly entering the greenhouse and causing a sudden drop in temperature. When the temperature is high, the system stops heating and starts cold water circulation, cooling the airflow through two pairs of airflows via bends and fins to prevent overheating inside the greenhouse. This intelligent temperature control adjustment requires no manual intervention, effectively maintaining the constant environment required for kiwi fruit growth and improving crop quality and yield.

[0019] 2. As described in 1, the system employs dual motors working in tandem. Motor 1 drives the sealing plate to rotate, enabling precise opening and closing of the ventilation openings. Motor 2 drives the blades to rotate at high speed, generating forced airflow and efficiently delivering external air into the shed. Channel 1, Channel 2, and the main air duct are quickly connected via a threaded post and collar structure, requiring only the tightening of the threaded cap to complete the fixation without the need for complex tools.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Reference Figures 1-4An automatic opening and closing temperature control device for the ventilation openings of a kiwifruit isolation greenhouse includes a channel 1. A processor 11 is fixedly installed at the lower end of the channel 1, and a temperature probe 12 is fixedly installed at the lower end of the processor 11's housing. When ventilation is required, commands are sent to the processor 11, causing it to drive motors 15 and 17. Motor 15 can drive shaft 14 via a rotating shaft 1, causing the sealing plate 16 to rotate 90 degrees clockwise, allowing airflow through the channel 1. When closing, it can rotate 90 degrees counterclockwise to seal the channel. Motor 17 can drive shaft 18 via a rotating shaft 2, causing blades 19 to rotate, generating a conveying airflow. External air can enter the isolation shed. Both motor 15 and motor 2 17 are servo models. The cold water inlet 42 of the bend pipe 4 can be connected to the water pump through a water pipe to ensure stable delivery of cold water. The temperature probe 12 detects the temperature of the external environment. When the temperature is low, the water pump of the bend pipe 4 is turned off and the power supply of the electric heating tube 32 is turned on. The electric heating tube 32 can be heated to a specified temperature by setting the temperature control switch. The airflow passes through the area of ​​the electric heating tube 32 for air heating. Conversely, when the temperature is high, the water pump of the bend pipe 4 is started, the electric heating tube 32 is turned off, the cold water circulates inside the bend pipe 4, and the airflow passes through the area of ​​the bend pipe 4 for cooling.

[0027] One side of channel 1 has bushings 13 fixed through both the top and bottom ends. Inside the two bushings 13, shafts 14 are rotatably installed. At the bottom of channel 1, motor 15 is fixedly installed by a bracket. Inside motor 15, there is a rotating shaft for driving. The end of the rotating shaft is connected to shaft 14 by a coupling. The surface of shaft 14 inside channel 1 is fixedly wrapped with a sealing plate 16 for rotating opening and closing. The edge of sealing plate 16 is in close contact with the inner wall of channel 1. Driven by motor 15, the rotating shaft can drive shaft 14 to rotate, and drive sealing plate 16 to rotate to open and close the opening area of ​​channel 1.

[0028] A motor 17 is fixedly installed on the inner wall of channel 1 by a bracket. The motor 17 has a rotating shaft 2 for driving, and the end of the rotating shaft 2 is fixedly connected to the shaft rod 18 by a coupling. Several blades 19 are fixedly distributed on the surface of the shaft rod 18. Driven by the motor 17, the rotating shaft 2 can make the shaft rod 18 rotate, which in turn drives the blades 19 to rotate, thereby generating airflow and sending the outside air into the isolation shed.

[0029] One end of the channel 1 is connected to the channel 2, and the other end of the channel 2 is connected to the main air duct 21. The external airflow is transported through the channel 1, then through the channel 2, and finally through the main air duct 21 into the isolation shed.

[0030] Among them, several ceramic seats 3 are fixedly installed on the upper end of the inner wall of the second channel 2, and a ceramic sleeve 31 corresponding to the position of the ceramic seat 3 is also fixed through the lower end of the inner wall of the main air duct 21. The ceramic seat 3 and the ceramic sleeve 31 can stably install the electric heating tube 32.

[0031] The ceramic base 3 has an electric heating tube 32 inserted and fixed inside. The electric heating tube 32 extends downward through the ceramic sleeve 31. Several electric heating tubes 32 have multiple layers of fins 33 fixed on their surfaces along the vertical direction. The electric heating tubes 32 can be energized and connected to a temperature control switch via wires to adjust their temperature. The temperature control switch is connected to the processor 11 via a data cable. The temperature control switch can be intelligently operated by inputting commands and cooperating with the processor 11. The ceramic base 3 and the ceramic sleeve 31 provide insulation and heat insulation, preventing the heat from the electric heating tubes 32 from being transferred to the second channel 2. When the external temperature is low, the power supply to the electric heating tubes 32 can be turned on during ventilation, allowing the electric heating tubes 32 to heat up. Combined with the heat conduction effect of the fins 33, the airflow can be heated, preventing the airflow from entering the isolation shed and causing the internal temperature to drop.

[0032] Among them, a bend 4 is also installed through the inner wall of the second channel 2. Multiple layers of fins 41 are fixed on the surface of the bend 4 along the upper and lower positions. Cold water can be introduced into the inside of the bend 4. By the airflow contacting the cold water and the fins 41 for heat exchange, the temperature of the airflow can be reduced. When the external temperature is high during ventilation, the temperature of the airflow can be reduced to avoid the temperature inside the isolation shed becoming too high.

[0033] Both ends of the bend 4 extend downward through the inner wall of channel 2. One end of the bend 4 is provided with a cold water inlet 42, and the other end of the bend 4 is provided with a cold water outlet 43. Cold water can be introduced into the bend 4. Cold water can be delivered into the bend 4 through the cold water inlet 42, and cold water can be discharged from the bend 4 through the cold water outlet 43, thus realizing the circulation of cold water inside the bend 4.

[0034] Among them, threaded columns 5 are fixedly installed on both sides of the outer wall of channel 2 by brackets, and collars 51 are fixedly installed on both sides of channel 1 and main air duct 21. The surface of the threaded column 5 and the inside of the collar 51 are slidably sleeved, so that quick positioning can be achieved when channel 1 and channel 2 are connected and channel 2 and main air duct 21 are connected.

[0035] The threaded post 5 has a threaded cap 52 threaded at its end. One end of the threaded cap 52 is tightly fitted to the end face of the collar 51. When installing the channel 1, channel 2, and main air duct 21, the three are spliced ​​together. Channel 1 is located in the outdoor direction, the main air duct 21 is located in the indoor area, and channel 2 serves as a transition. During the connection, the threaded post 5 passes through the collar 51 to achieve the positioning of the three. The threaded cap 52 and the threaded post 5 are threaded together to fix the three.

[0036] Operating mode: Channel 1 is the main channel for airflow into the isolation shed. Its opening and closing state is controlled by motor 15 driving the sealing plate 16 through shaft 14. When the temperature probe 12 detects that the ambient temperature has reached the preset ventilation threshold, the processor 11 sends a command to motor 15. The rotating shaft of motor 15 drives shaft 14 to rotate 90 degrees, so that the sealing plate 16 changes from a vertical closed state to a horizontal open state, and airflow can enter through channel 1. At the same time, motor 2 17 starts, and its rotating shaft 2 drives shaft 2 18 to rotate, which drives blade 19 to rotate and generate forced airflow, accelerating the delivery of external air through channel 1 to channel 2. If the temperature drops, the processor 11 controls motor 15 to reverse, the sealing plate 16 resets and closes channel 11, and motor 2 17 stops synchronously, realizing intelligent control of the ventilation opening.

[0037] When the temperature probe 12 detects a low temperature requiring heating, the processor 11 shuts off the cold water circulation in the bend 4 and starts the electric heating element 32. The electric heating element 32 is fixed in the channel 2 by the ceramic base 3 and the ceramic sleeve 31. After being powered on, it heats up, and its multi-layer fins 33 expand the contact area with the airflow. When the cold air flows through the area of ​​the electric heating element 32, it is heated and then sent into the isolation shed through the main air duct 21. The temperature control switch is linked with the processor 11 and can set the target temperature of the electric heating element 32 to avoid overheating. The insulation properties of the ceramic base 3 and the ceramic sleeve 31 prevent heat from being transferred to the channel 2, ensuring that the heat energy is concentrated for airflow heating. If the ambient temperature rises, the processor 11 cuts off the power to the electric heating element 32 and stops heating, thus realizing dynamic temperature regulation.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
