Description

Technical Field

[0001] This utility model relates to the field of silkworm rearing equipment technology, specifically to a silkworm rearing temperature and humidity control device. Background Technology

[0002] In silkworm rearing, temperature and humidity are key factors affecting the growth, development, and health of silkworms. Silkworms have strict requirements for temperature and humidity at different growth stages. For example, suitable temperature and humidity are needed to ensure a high hatching rate during egg incubation; in the larval stage, excessively high or low temperature and humidity will affect their feeding and growth rate; and during the silkworm's cocoon-spinning stage, appropriate temperature and humidity are crucial for ensuring cocoon quality and yield. Currently, traditional silkworm rearing methods mostly rely on manual experience to control temperature and humidity, using simple thermometers and hygrometers for monitoring, and then adjusting by opening doors and windows for ventilation, using heating equipment, or humidifiers. This method has the following drawbacks: First, manual monitoring is prone to error and cannot obtain accurate temperature and humidity data in real time; second, adjustment measures are not timely or precise enough, which may lead to large fluctuations in temperature and humidity, which is detrimental to the stable growth of silkworms; third, it consumes a lot of manpower, increasing the cost of silkworm rearing, and in large-scale silkworm farms, it is difficult to achieve comprehensive and effective temperature and humidity management for each silkworm rearing room.

[0003] Chinese utility model patent (application number: 202023195741.X) discloses an automatic control system for silkworm rearing room temperature and humidity, relating to the field of silkworm rearing technology. The system includes: a controller; a heating and cooling device, a humidification and dehumidification device, and a temperature and humidity sensor, all communicatively connected to the controller. The heating and cooling device includes a heating and cooling air conditioner installed on the wall of the silkworm rearing room and an electric heater placed on the floor. The humidification and dehumidification device includes a humidifier and a ventilation device. The humidifier has humidification pipes, and the humidification pipes have multiple spray nozzles. The ventilation device includes an exhaust fan and an intake fan. This system can automatically monitor and adjust the temperature and humidity of the silkworm rearing room to ensure that the temperature and humidity meet the requirements. However, this system requires a separate, dedicated silkworm rearing room, which is costly for small-scale silkworm farmers and lacks portability and flexibility. Utility Model Content

[0023] like Figure 1 As shown, the silkworm rearing temperature and humidity control device disclosed in this embodiment includes a housing 1, a control box 2 located outside the housing 1, a temperature and humidity regulating component 3 located inside the housing 1 and electrically connected to the control box 2, and a protective component 4 located outside the housing 1. The housing 1 contains a rearing space, and a rearing support 11 for placing silkworm trays is provided within the rearing space. The protective component 4 includes a rain cover 41 located outside the housing 1 and a sunshade 42 located on top of the housing 1. The rain cover 41 is made of PVC plastic and has good waterproof performance, preventing rainwater from entering the housing 1 and protecting the silkworms and equipment inside from damage. It adapts to the needs of silkworm rearing under different weather conditions and extends the service life of the device. The sunshade 42 is made of sun-proof and heat-insulating material, effectively blocking direct sunlight, reducing the rate of temperature rise in the housing 1 during the day, and reducing the workload of the heating device.

[0024] The box 1 is made of polystyrene insulation board, which has good heat insulation performance. Inside it are three layers of bamboo and wood breeding racks 11, with ventilation holes evenly distributed on each layer of breeding racks 11 for placing silkworm trays.

[0025] Specifically, the temperature and humidity control component 3 includes a temperature and humidity sensor 31, a heating mechanism 32, a humidification mechanism 33, and a ventilation mechanism 34, all housed within the enclosure 1. The temperature and humidity sensor 31 monitors the temperature and humidity data within the enclosure in real time and transmits the data to the control box 2. The control box 2 has a built-in microcontroller or PLC (Programmable Logic Controller) with preset temperature and humidity standard parameter ranges for different silkworm growth stages. Parameters can be set and modified via a human-machine interface, facilitating personalized adjustments based on the growth needs of different silkworm varieties and batches. The control box also has data storage capabilities, recording temperature and humidity changes and the operating status information of each device, facilitating subsequent data analysis and troubleshooting, and providing a basis for optimizing silkworm rearing temperature and humidity control strategies. The control box 2 receives and processes the temperature and humidity data, issuing control commands based on set temperature and humidity thresholds. The heating mechanism 32, humidification mechanism 33, and ventilation mechanism 34 are all electrically connected to the control box 2 and are controlled by the control box 2 to regulate the temperature and humidity environment within the enclosure 1.

[0026] Preferably, multiple temperature and humidity sensors 31 are provided, and the multiple temperature and humidity sensors 31 are respectively set at different heights on the inner side wall of the box 1 to detect the temperature and humidity at different heights inside the box 1. The heating mechanism 32 includes an electric heater 321 and a cooling fan 322 installed inside the box 1. The electric heater 321 heats the air to increase the temperature inside the box 1, and the cooling fan 322 promotes the circulation of hot air inside the box, making the temperature distribution more uniform. Preferably, the heating element of the electric heater 321 is a PTC ceramic heating element or an electric heating wire, which has the characteristics of fast heating speed, good constant temperature performance, and high safety. The humidification mechanism 33 is an ultrasonic humidifier installed inside the box 1. The ultrasonic humidifier is connected to an external water source. Through ultrasonic vibration, the water in the water tank is atomized into tiny water droplets, which are diffused into the air inside the box, increasing the air humidity and making the air around the humidifier heavier. As the air humidity in the lower part of the box 1 increases, the heavier humid air will gradually sink, thereby pushing the drier air in the upper part to flow downwards, forming an air convection circulation. During the circulation process, the water droplets at the bottom are carried to the top of the chamber 1, achieving a uniform distribution of humidity.

[0027] Furthermore, the ultrasonic humidifier can be connected to a water storage tank, which is located on the outside of the housing 1 and connected to the ultrasonic humidifier via a water pipe. When the humidity inside the housing 1 is lower than the set value, the control box 2 controls the ultrasonic humidifier to work, atomizing the water in the storage tank into tiny water droplets to increase air humidity. The storage tank is equipped with a float-type water level detection device. When the water level is lower than the set value, the float drops, triggering a micro switch and sending a water shortage alarm signal to the control box 2. At the same time, it can be connected to an automatic water supply system for water replenishment.

[0028] The ultrasonic humidifier and electric heater 321 are respectively located on both sides of the bottom of the inner cavity of the chamber 1. The cooling fan 322 is located at the bottom of the inner cavity of the chamber 1 and close to the cooling fan 322, so as to quickly dissipate heat to all corners of the chamber 1 and accelerate the uniform distribution of temperature inside the chamber. The ultrasonic humidifier and electric heater 321 are positioned relatively far apart to prevent mutual interference between them.

[0029] The ventilation system 34 includes an intake fan 341 and an exhaust fan 342 positioned opposite each other on both sides of the housing 1. The intake fan 341 is located at the lower part of the housing 1 near the ultrasonic humidifier, and the exhaust fan 342 is located at the upper part of the housing 1 near the electric heater 321. The cooling fan 322 directs airflow towards the left side of the housing 1, blowing the hot air generated by the electric heater 321 and the water droplets generated by the ultrasonic humidifier together into the silkworm rearing area inside the housing 1. This effectively mixes and diffuses the hot air and water droplets to the left and middle areas of the housing 1. The intake fan 341 directs airflow towards the interior of the housing, introducing fresh air to provide sufficient oxygen and promote air circulation. The intake fan 341 can introduce cooler outside air into the bottom of the housing 1, mixing it with the hot air generated by the electric heater 321 and the water droplets generated by the ultrasonic humidifier; the exhaust fan 342 directs airflow towards the exterior of the housing 1, expelling the hot air and moisture from inside the housing 1. Due to the principle of hot air rising, the hot air and moisture in the upper part of the enclosure 1 are exhausted by the exhaust fan 342, while a negative pressure is formed inside the enclosure 1, prompting fresh air to enter from the intake fan 341, maintaining air circulation inside the enclosure 1. Through the coordinated work of the intake fan 341, the cooling fan 322, and the exhaust fan 342, hot air and water droplets can be evenly distributed in all corners of the enclosure 1, avoiding excessive local temperature and humidity differences. The cooling fan 322 is installed between the electric heater 321 and the ultrasonic humidifier, which can effectively reduce direct interference between the two, and the air duct design makes their operation more coordinated.

[0030] Five SHT20 temperature and humidity sensors (31) are installed inside the enclosure 1 at different heights and corners. They are connected to the control box 2 via data cables to monitor the temperature and humidity changes inside the enclosure 1 in real time. The control box 2 uses an STC89C52 microcontroller and is installed on the outside of the enclosure 1. It is preset with standard temperature and humidity parameters for different growth stages of silkworms, such as 23-25℃ and 70%-80% humidity during the egg hatching stage; 26-28℃ and 75%-85% humidity during the larval stage; and 24-26℃ and 65%-75% humidity during the mature cocooning stage. The electric heater (321) is a PTC ceramic electric heater installed at the bottom of the enclosure 1 and equipped with a small cooling fan (322). When the temperature and humidity sensor (31) detects that the internal temperature of the enclosure 1 is lower than the set value, the control box 2 receives the signal and controls the electric heater (321) to work. At the same time, the cooling fan starts, allowing hot air to diffuse evenly into the enclosure and raise the temperature to the set range. Both the intake fan 341 and the exhaust fan 342 are DC speed-regulating fans. The air volume is adjusted by the control box 2 according to the temperature and humidity inside the box 1. When the temperature or humidity inside the box 1 is too high, the air volume of the exhaust fan 342 is increased to expel hot air and moisture, while the air volume of the intake fan 341 is increased to introduce fresh air and maintain the freshness of the air and the balance of temperature and humidity inside the box 1.

[0031] Preferably, the silkworm rearing temperature and humidity control device also includes an alarm 5 installed on the top of the housing 1, which is electrically connected to the control box 2. The alarm 5 is an audible and visual alarm. When the temperature and humidity inside the housing 1 exceed the set threshold range, and the heating mechanism 32, humidification mechanism 33, and ventilation mechanism 34 have not returned to normal after working continuously for 30 minutes, the control box 2 triggers the audible and visual alarm to remind staff to check the equipment or take other measures in a timely manner.

[0032] Preferably, the silkworm rearing temperature and humidity control device also includes a solar photovoltaic panel 6 installed on the top of the sunshade 42. The housing 1 has a built-in power supply, and the solar photovoltaic panel 6 is used to charge the power supply. The power supply is a lithium battery pack, installed in the battery box at the bottom of the outer side of the housing 1, and connected to the mains power through a charging interface. Under normal circumstances, it is in a charging standby state. When there is a power outage or no power supply in the field, it can provide power support for more than 8 hours to the control box 2, temperature and humidity sensor 31, heating mechanism 32, humidification mechanism 33 and ventilation mechanism 34, ensuring uninterrupted operation of the device and ensuring that the silkworms can be in a suitable temperature and humidity environment under special circumstances, thus enhancing the emergency response capability of the device.

[0033] In summary, the silkworm rearing temperature and humidity control device of this embodiment transforms the silkworm rearing room into a box, and a protective component 4 is installed on the outside of the box 1 to prevent wind, rain, and sun. While ensuring that the box 1 can be moved, it also ensures the adaptability of the box 1 to harsh environments, providing a better, more portable, and lower-cost silkworm rearing option for small and medium-sized silkworm farmers.
