Description
Technical Field
[0001] This utility model belongs to the field of greenhouse cultivation technology, specifically relating to an automatic humidity control device for orchid greenhouses. Background Technology
[0002] Humidity management is a core aspect of orchid greenhouse cultivation. By maintaining suitable humidity levels within the greenhouse, simulating the orchid's natural environment, it promotes photosynthesis and healthy growth, prevents disease, and improves flowering quality. Common humidity control methods in existing orchid greenhouses include: monitoring humidity by placing hygrometers at fixed locations within the greenhouse; increasing humidity by spraying water through sprinkler pipes and nozzles on the roof; and reducing humidity by opening skylights or side windows and using circulating fans to promote airflow. While these methods and devices can control humidity in orchid greenhouses, the fixed placement of hygrometers and nozzles lacks flexibility. Therefore, this application proposes a flexible automatic humidity control device for orchid greenhouses, enabling mobile humidity monitoring and mobile spraying within the greenhouse. Utility Model Content
[0003] To address the shortcomings of existing technologies, this utility model proposes an automatic humidity control device for orchid greenhouses. This automatic control device can perform mobile humidity monitoring and mobile spraying within the greenhouse, and can spray targeted locations.
[0004] This utility model is achieved through the following technical solution: An automatic humidity control device for orchid greenhouses includes a mobile monitoring and spraying mechanism. This mechanism mainly comprises a U-shaped trough, a sliding base, a traction mechanism, a humidity sensor, a spray pipe, nozzles, and a water supply hose. The U-shaped trough is installed at the top of the greenhouse, extending along its length, serving as the installation base. The sliding base is slidably mounted on the U-shaped trough, and a traction mechanism is installed between the two ends of the U-shaped trough to drive the sliding base to reciprocate on the trough. The humidity sensor and the spray pipe are both mounted on the sliding base, and nozzles for spraying are installed on the spray pipe. The water supply hose is laid at the bottom of the U-shaped trough, with its right end extending from the right end of the U-shaped trough and connected to a high-pressure water source, and its left end connected to the spray pipe. The water supply hose delivers high-pressure water for spraying between the high-pressure water source and the spray pipe. When the sliding base reciprocates on the U-shaped trough, the left end of the water supply hose is pulled by the sliding base and moves accordingly. The water supply hose is flexible and can be dragged within the U-shaped trough to ensure water supply for spraying.
[0005] Furthermore, the bottom surfaces at both ends of the slide are equipped with left-right spaced and rollable guide wheels. L-shaped baffles are fixedly installed on the inner or outer walls of both sides of the top of the U-shaped groove. The L-shaped baffles and the groove walls of the U-shaped groove form a U-shaped track for the guide wheels to pass through. The slide moves on the U-shaped groove using the guide wheels, which can reduce the friction of movement and make it move more smoothly.
[0006] Furthermore, both sides of the top of the U-shaped groove are integrally formed with flanges, and the flanges are located on the upper side of the L-shaped baffle. The flanges form a protective barrier on the upper edge of the guide wheel, which can prevent the guide wheel from leaving the U-shaped track and prevent the slide from tipping over and falling off the U-shaped groove.
[0007] Furthermore, the traction mechanism mainly consists of a reel, a fixed pulley, a traction rope, and a motor. Two reels are provided, both of which are rotatably installed at the right end of the U-shaped groove and are spaced apart. The fixed pulley is installed at the left end of the U-shaped groove, and the traction rope is wrapped around the fixed pulley. The two ends of the traction rope are fixed and wound around the two reels respectively. The motor is installed at the right end of the U-shaped groove, and both reels are connected to the power output end of the motor. The motor is used to drive the two reels to rotate synchronously, with one reel winding up the traction rope and the other reel unwinding the traction rope. The two traction ropes between the fixed pulley and the reel pass through the slide block, and the slide block is fixedly connected to one of the traction ropes. When winding and unwinding the traction rope, the slide block can move back and forth on the U-shaped groove.
[0008] Furthermore, each of the reels is equipped with a directional pulley for guiding the traction rope, and the traction rope is wrapped around the directional pulley so that the two traction ropes between the fixed pulley and the reel are parallel to each other.
[0009] Furthermore, the spray pipe has a T-shaped tubular structure, with the middle section of the spray pipe fixed on the slide block so that it can move with the slide block. The left end of the water supply hose is connected to the interface in the middle of the spray pipe. The front and rear ends of the spray pipe extend to the front and rear sides of the slide block, respectively, and both ends are sealed. The bottom of both ends of the spray pipe is provided with multiple branch pipes that are spaced apart along its axial direction. Each branch pipe is equipped with a nozzle at its bottom end. The spray coverage area can be expanded by using multiple nozzles.
[0010] Furthermore, the automatic control device also includes at least one circulating fan installed inside the greenhouse for circulating air inside and outside the greenhouse. When the humidity inside the greenhouse is high, the circulating fan, as well as the greenhouse doors, skylights, or side windows, are turned on to promote air circulation inside and outside the greenhouse and use air circulation to remove moisture from the greenhouse to reduce humidity.
[0011] As can be seen from the above technical solution, the beneficial effects of the automatic humidity control device for orchid greenhouses provided by this utility model are as follows: This automatic control device can be installed inside orchid greenhouses for monitoring and controlling humidity. The traction mechanism drives a sliding block to reciprocate on a U-shaped trough, thereby moving the humidity sensor and nozzle mounted on the sliding block. The humidity sensor can perform mobile humidity monitoring inside the greenhouse. When the sliding block reciprocates on the U-shaped trough, the left end of the water supply hose moves along with it due to the traction of the sliding block. The water supply hose is flexible and can be dragged within the U-shaped trough to ensure water supply for spraying. The nozzle can move with the sliding block to perform mobile spraying inside the greenhouse. The nozzle can move with the sliding block to a specific location inside the greenhouse for spraying, which is especially suitable when the humidity sensor detects that the humidity in a certain area of the greenhouse is low. The nozzle can then spray locally to increase the humidity in that area. Attached Figure Description

Therefore, they should not be construed as limitations on this utility model.
[0019] An automatic humidity control device for orchid greenhouses, such as Figures 1 to 3 As shown, it mainly consists of a mobile monitoring and spraying mechanism and a circulating fan. The mobile monitoring and spraying mechanism mainly consists of a U-shaped trough 1, a sliding base 2, a traction mechanism 5, a humidity sensor 6, a spray pipe 7, a nozzle 12, and a water supply hose 8. The traction mechanism 5 mainly consists of a reel 5.1, a fixed pulley 5.4, a traction rope 5.3, and a motor 5.5.
[0020] The U-shaped groove 1, as Figures 1 to 3 As shown, it is made of stainless steel and has the characteristics of high strength, good load-bearing capacity and not easy to bend. The U-shaped trough 1 is installed on the top of the greenhouse and extends along the length of the greenhouse, spanning the entire greenhouse, serving as the installation base and the running track of the slide 2. like Figure 1 As shown, the bottom of the U-shaped trough 1 is provided with a plurality of drainage holes 1.1 along its length to prevent water accumulation in the U-shaped trough 1.
[0021] The slide 2, as Figure 1 and Figure 2 As shown, it is made of stainless steel or aluminum alloy, designed to ensure its load-bearing capacity while controlling its overall weight. The slide 2 is slidably set on the U-shaped groove 1, which serves as the mounting base for the humidity sensor 6 and the spray pipe 7.
[0022] Specifically, such as Figure 1 and Figure 2 As shown, guide wheels 3 that are spaced apart and can roll are installed on the bottom surfaces of both ends of the slide block 2. L-shaped baffles 4 are fixedly installed on the inner walls of both sides of the top of the U-shaped groove 1. A U-shaped track is formed between the L-shaped baffles 4 and the groove wall of the U-shaped groove 1, allowing the guide wheels 3 to pass through. The slide block 2 moves on the U-shaped groove 1 using the guide wheels 3, which can reduce the friction of movement and make it move more smoothly. like Figures 1 to 3 As shown, both sides of the top of the U-shaped groove 1 are integrally formed with flanges 9, and the flanges 9 are located on the upper side of the L-shaped baffle 4. The flanges 9 form a protective barrier on the upper edge of the guide wheel 3, which can prevent the guide wheel 3 from leaving the U-shaped track and prevent the slide 2 from tipping over and falling off the U-shaped groove 1.
[0023] The traction mechanism 5, such as Figure 1 and Figure 3 As shown, there are two reels 5.1, both rotatably mounted on the right end of the U-shaped trough 1 and spaced back-to-back. Specifically, the two reels 5.1 share a common shaft. A fixed pulley 5.4 is mounted on the left end of the U-shaped trough 1. A traction rope 5.3 is wound around the fixed pulley 5.4, with both ends of the traction rope 5.3 fixed and wound around the two reels 5.1 respectively. The traction rope 5.3 and the reels 5.1 form two strands of traction rope 5.3 spaced back-to-back. A motor 5.5 is mounted on the right end of the U-shaped trough 1, and both reels 5.1 are connected to the power output end of the motor 5.5. Specifically, the shaft of the reel 5.1 is fixed to the power output end of the motor 5.5. The motor 5.5 is a stepper motor with a reducer. The motor 5.5 or servo motor 5.5 are both existing products, and their specific models are conventionally selected. This application does not involve structural improvements to the motor 5.5. The motor 5.5 is used to drive the two reels 5.1 to rotate synchronously. One reel 5.1 winds up the traction rope 5.3, and the other reel 5.1 unwinds the traction rope 5.3. The two traction ropes 5.3 between the fixed pulley 5.4 and the reel 5.1 both pass through the slide block 2. Specifically, the top surface of the slide block 2 is provided with a channel for the traction rope 5.3 to pass through, and the slide block 2 is fixedly connected to one of the traction ropes 5.3. Specifically, the traction rope 5.3 is fixed to the top surface of the slide block 2 by a metal pressure plate. When winding and unwinding the traction rope 5.3, it can drive the slide block 2 to move back and forth on the U-shaped groove 1. Specifically, one end of the traction rope 5.3 is fixed to one of the reels 5.1 and wound clockwise on reel 5.1, while the other end of the traction rope 5.3 is fixed to the other reel 5.1 and wound counterclockwise on reel 5.1. The length of the traction rope 5.3 wound on reel 5.1 is greater than the length of the U-shaped groove 1. When the two reels 5.1 rotate synchronously, the traction rope 5.3 can be wound and unwound synchronously, thereby driving the slide 2 to move; Figure 1 As shown, each reel 5.1 is equipped with a directional pulley 5.2 for guiding the traction rope 5.3. The traction rope 5.3 is wrapped around the directional pulley 5.2, so that the two strands of traction rope 5.3 between the fixed pulley 5.4 and the reel 5.1 are parallel front to back. Specifically, as shown... Figure 4 As shown, the reversing pulley 5.2 consists of two support plates spaced apart front and rear, and a pulley rotatably connected to the bottom of the two support plates; In addition, the traction mechanism 5 can also adopt conventional traction mechanisms such as sprockets and chains, pulleys and belts, which will not be described in detail here.
[0024] The humidity sensor 6 is an existing product, specifically a conventional model. At least one humidity sensor 6 is mounted on the slide 2. Figure 2As shown, when installing multiple humidity sensors 6, the mounting bracket can be used to arrange the multiple humidity sensors 6 at intervals in the front-to-back direction to ensure the humidity monitoring coverage in the front-to-back direction.
[0025] The spray pipe 7, such as Figure 1 and Figure 2 As shown, it is a T-shaped tubular structure made of rigid plastic or metal material, which serves as the mounting base for the nozzle 12. The spray pipe 7 is installed on the left end of the slide 2, and the middle section of the spray pipe 7 is fixed on the slide 2 so that it can move with the slide 2. The front and rear ends of the spray pipe 7 extend to the front and rear sides of the slide 2, respectively. Both the front and rear ends are sealed structures. The bottom of both the front and rear ends of the spray pipe 7 are provided with multiple branch pipes 11 that are spaced apart along its axial direction. Each branch pipe 11 is equipped with a nozzle 12 at its bottom end. The spray coverage area can be expanded by using multiple nozzles 12.
[0026] The water supply hose 8, such as Figure 1 and Figure 2 As shown, it is laid at the bottom of the U-shaped trough 1, and its length can extend from the right end to the left end of the U-shaped trough 1. Its right end is led out from the right end of the U-shaped trough 1 and connected to a high-pressure water source (such as spray water pressurized by a booster pump). Its left end passes under the slide 2 and is connected to the interface in the middle of the spray pipe 7. The water supply hose 8 delivers the high-pressure water required for spraying between the high-pressure water source and the spray pipe 7. When the slide 2 moves from left to right, the water supply hose 8 bends and folds back in the U-shaped trough 1 on the left side of the slide 2 and moves with the slide 2.
[0027] The circulating fan is installed in the orchid greenhouse at least one circulating fan (not shown in the figure) for circulating the air inside and outside the greenhouse. When the humidity inside the greenhouse is high, the circulating fan, as well as the doors, skylights or side windows of the greenhouse, are turned on to promote the air flow inside and outside the greenhouse. The air circulation removes the moisture inside the greenhouse to reduce the humidity. The circulating fan can be an axial fan, which is widely used in existing orchid greenhouses and will not be described in detail here.
[0028] In addition, the automatic control device also includes a PLC controller (not shown in the figure). The motor 5.5, humidity sensor 6 and circulating fan are all electrically connected to the PLC controller. The PLC controller is an existing product. The PLC controller can control the forward and reverse rotation of the motor 5.5 and has a timing function. It can be set according to its product manual. It is intended to control the reciprocating frequency and speed of the slide 2 on the U-shaped groove 1. The humidity sensor 6 transmits the detection signal to the PLC controller. After receiving the signal, the PLC controller controls the high-pressure water source to send water to the nozzle 12 for spraying according to the humidity value, or turns on the circulating fan to circulate the air inside and outside the greenhouse to remove the moisture in the greenhouse, so as to achieve the purpose of automatically adjusting the humidity in the greenhouse. The circuitry for the humidity sensor 6 is installed inside the U-shaped trough 1.
[0029] To improve the structural stability of the U-shaped trough 1, the bottom of the U-shaped trough 1 is provided with supporting beams 10 that are spaced apart in the left-right direction and extend in the front-back direction. The front and rear ends of the supporting beams 10 can be fixed to the greenhouse to form support for the U-shaped trough 1, which can improve the stability of the U-shaped trough 1 and prevent the U-shaped trough 1 from bending under load due to the large span. In addition, the number of supporting beams 10 and the spacing between two adjacent supporting beams 10 can be increased accordingly based on the span of the U-shaped channel 1.
[0030] In addition, the number of mobile monitoring and spraying devices arranged inside the orchid greenhouse should be adjusted according to the width of the greenhouse to ensure the coverage of humidity monitoring and spraying. When the greenhouse is wide, multiple mobile monitoring and spraying devices can be arranged at intervals along its width inside the greenhouse.
[0031] The operating principle of this automatic control device for humidity management in orchid greenhouses is as follows: When the automatic control device is running, the humidity sensor 6 on the slide 2 moves to monitor humidity. Specifically, the motor 5.5 of the traction mechanism 5 operates to drive the traction rope 5.3 to wind and unwind. When the traction rope 5.3 moves between the reel 5.1 and the fixed pulley 5.4, it drives the slide 2 to move on the U-shaped trough 1, thereby driving the humidity sensor 6 to perform mobile humidity monitoring inside the shed. When the slide 2 moves back and forth on the U-shaped trough 1, the left end of the water supply hose 8 is pulled by the slide 2 and moves accordingly. The water supply hose 8 is flexible and can be dragged in the U-shaped trough 1 to ensure the spray water supply. Based on the humidity value monitored by humidity sensor 6, the PLC controller compares it with the humidity threshold. When the real-time humidity value is lower than the humidity threshold, the PLC controller controls the high-pressure water source (booster pump) connected to the water supply hose 8 to start sending water to the spray pipe 7 and spraying it through the nozzle 12 to increase the humidity in the greenhouse. In addition, if the humidity sensor 6 detects that the humidity value in a local area is too low, it can spray the local area. When the real-time humidity value is higher than the humidity threshold, the PLC controller controls the circulation fan to start. In conjunction with the opened greenhouse doors and windows, the circulation fan promotes air circulation inside and outside the greenhouse, using air circulation to remove moisture from the greenhouse and reduce humidity.
