Description

Technical Field

[0001] This utility model relates to the technical field of silkworm breeding equipment, specifically to a carbon dioxide adaptive ventilation device for silkworm rearing rooms. Background Technology

[0002] Silkworm silk is a precious textile raw material, mainly used for weaving silk fabrics. It is an excellent textile material and also has wide applications in military and electrical industries. Silkworm pupae, moths, and silkworm excrement can also be utilized comprehensively, serving as raw materials for various chemical and pharmaceutical industries, and can also be used as plant fertilizer. With the rapid development of industry and agriculture, the demand for materials produced by silkworms is increasing, leading to the flourishing of silkworm farming. Silkworm rearing rooms are dedicated spaces for the feeding and growth of silkworms and are an indispensable infrastructure in silkworm production.

[0003] Existing carbon dioxide adaptive ventilation equipment for silkworm rearing rooms typically uses a carbon dioxide sensor as the core sensing element, combined with a fan, fixed air ducts, and a basic control system. The sensor is installed inside the silkworm rearing room to monitor the carbon dioxide concentration. When the concentration exceeds the standard, the control system drives the fan to exchange air through the air ducts. Some devices allow manual setting of thresholds to control the fan's start and stop, while a few can achieve simple adjustment of the fan speed. The overall structure leans towards basic automation, mainly relying on mechanical ventilation to improve the air quality in the silkworm rearing room.

[0004] The shortcomings of the existing technical solutions are as follows: due to the varying sizes of silkworm rearing rooms and the dynamic changes in silkworm density during the rearing stage in actual breeding, fixed air ducts are difficult to adapt to the air supply needs of different scenarios: when the silkworm rearing room is large or the silkworm density is high, the fixed air supply range cannot cover the entire rearing area, which can easily create ventilation dead zones; when the silkworm rearing room is small or the silkworm density is low, the fixed air exchange intensity may lead to excessive local air exchange, which not only wastes energy but also disrupts the temperature and humidity balance of the silkworm rearing room, affecting the stability of the silkworm growth environment, and thus restricting the improvement of breeding efficiency and product quality.

[0018] The specific embodiments of this utility model are described in detail below, but it should be understood that the scope of protection of this utility model is not limited to the specific embodiments.

[0019] like Figures 1 to 4 As shown, a carbon dioxide adaptive ventilation device for silkworm rearing includes a detection mechanism, a ventilation mechanism, and a control terminal. The detection mechanism includes a carbon dioxide sensor, which is fixedly installed inside the silkworm rearing room. The ventilation mechanism includes a fan, a ventilation box 1, casters 2, and a ventilation pipe. The fan is fixedly installed outside the silkworm rearing room, and the ventilation box 1 is installed inside the silkworm rearing room. Several casters 2 are arranged in a rectangular array and fixedly installed at the bottom of the ventilation box 1. An air inlet 3 is opened on the top of the ventilation box 1, and an exhaust port 4 connected to the air inlet 3 is opened on the side of the ventilation box 1. One end of the ventilation pipe is connected to the output end of the fan, and the other end of the ventilation pipe is connected to the air inlet 3. The carbon dioxide sensor and the fan are both electrically connected to the control terminal. A flow guiding component 5 is also provided inside the exhaust port 4.

[0020] A carbon dioxide sensor monitors the carbon dioxide concentration in the silkworm rearing room in real time and transmits the data to a control terminal. When the concentration exceeds the standard, the control terminal starts the fan, and fresh outside air enters the air exchange box 1 through the ventilation duct, and is then guided into the silkworm rearing room through the guide component 5 of the exhaust port 4. The casters 2 facilitate the movement of the air exchange box 1 to adapt to different silkworm rearing room layouts and silkworm density. The control terminal adjusts the fan operation according to the carbon dioxide concentration, and shuts off the fan when the concentration returns to normal.

[0021] The movable ventilation box 1 and the air guide component 5 solve the problem of limited ventilation range of fixed air ducts, and can flexibly adapt to different sizes of silkworm houses and silkworm density, reducing ventilation dead corners and local over-ventilation; the casters 2 improve the mobility of the equipment, enhance its adaptability to the silkworm house environment, and ensure the stability of the silkworm growth environment.

[0022] According to one embodiment of the present invention, the flow guiding assembly 5 includes a first flow guiding plate 6. A plurality of first flow guiding plates 6 are arranged at equal intervals along the transverse direction within the air exchange box 1. Each first flow guiding plate 6 includes a first rotating shaft 7 and a first guide plate 8. The first rotating shaft 7 is vertically rotatably disposed at the port of the exhaust port 4, and the first guide plate 8 is fixedly disposed on the side of the first rotating shaft 7. The first flow guiding plate 6 also includes a first synchronous pulley 9, a second synchronous pulley 10, a first synchronous belt 11, and a second synchronous belt 12. The first synchronous pulley 9 and the second synchronous pulley 10 are both coaxially and fixedly connected to the first rotating shaft 7. The first synchronous belt 11 is disposed between the first synchronous pulleys 9 of two adjacent first flow guiding plates 6, and the second synchronous belt 12 is disposed between the second synchronous pulleys 10 of two adjacent first flow guiding plates 6. The flow guiding assembly 5 also includes a first motor. The first motor is fixedly connected to the air exchange box 1, and its output end is coaxially and fixedly connected to the first rotating shaft 7. The first motor is electrically connected to a control terminal, and the first synchronous pulley 9 is located above the second synchronous pulley 10.

[0023] The first motor drives the first rotating shaft 7 connected to it to rotate. Through the cooperation of the first synchronous pulley 9, the second synchronous pulley 10, the first synchronous belt 11, and the second synchronous belt 12, all the first rotating shafts 7 rotate synchronously, thereby causing the first guide plate 8 to adjust its angle synchronously, changing the air delivery direction and range of the exhaust port 4. The control terminal controls the first motor according to the situation inside the silkworm house to adjust the angle of the first guide plate 8, achieving precise air delivery.

[0024] By simultaneously adjusting multiple first guide vanes 6, the airflow direction and range can be quickly changed to adapt to different ventilation needs; synchronous belt drive ensures the consistency of adjustment and improves the accuracy of airflow guidance; the first motor is connected to the control terminal to realize automated adjustment, thereby improving the intelligence level and ventilation efficiency of the equipment.

[0025] According to one embodiment of the present invention, the flow guiding assembly 5 includes a second flow guiding plate 13. A plurality of second flow guiding plates 13 are arranged longitudinally at equal intervals within the air exchange box 1. Each second flow guiding plate 13 includes a second rotating shaft 14 and a second guide plate 15. The second rotating shaft 14 is horizontally rotatably disposed at the port of the exhaust port 4, and the second guide plate 15 is fixedly disposed on the side of the second rotating shaft 14. The second flow guiding plate 13 also includes a third synchronous pulley 16, a fourth synchronous pulley 17, a third synchronous belt 18, and a fourth synchronous belt 19. The third synchronous pulley 16 and the fourth synchronous pulley 17 are both coaxially and fixedly connected to the second rotating shaft 14. The third synchronous belt 18 is disposed between the third synchronous pulleys 16 of two adjacent second flow guiding plates 13, and the fourth synchronous belt 19 is disposed between the fourth synchronous pulleys 17 of two adjacent second flow guiding plates 13. The flow guiding component 5 also includes a second motor, which is fixedly connected to the air exchange box 1. The output end of the second motor is fixedly connected to the second rotating shaft 14 on the same axis. The second motor is electrically connected to the control terminal. The third synchronous pulley 16 and the fourth synchronous pulley 17 are located at the two ends of the second rotating shaft 14, respectively.

[0026] The second motor drives the corresponding second rotating shaft 14 to rotate. With the help of the third synchronous pulley 16, the fourth synchronous pulley 17, the third synchronous belt 18, and the fourth synchronous belt 19, all the second rotating shafts 14 rotate synchronously, causing the second guide plate 15 to adjust its angle synchronously, thereby changing the air delivery angle and coverage of the exhaust port 4. The control terminal can control the second motor according to actual needs to achieve precise control of the air delivery direction.

[0027] The second guide plate 13, arranged longitudinally, can adjust the air delivery angle over a wider range, further expanding the ventilation coverage area; the synchronous belt drive ensures the consistency of adjustment of each second guide plate 15, improving the uniformity of ventilation; the automated adjustment method makes the equipment operation more convenient and can better adapt to changes in silkworm population density and other situations.

[0028] According to one embodiment of this utility model, the detection mechanism further includes a temperature sensor, which is fixedly installed inside the silkworm house. The ventilation mechanism further includes a heating component, which is fixedly installed inside the air inlet 3. Both the temperature sensor and the heating component are electrically connected to a control terminal. The heating component includes an electric heating coil, which is fixedly installed inside the air inlet 3 and electrically connected to the control terminal.

[0029] Temperature sensors monitor the temperature inside the silkworm rearing room in real time and transmit the data to the control terminal. When ventilation may cause the temperature to drop below the suitable range, the control terminal activates the heating coil of the heating component to heat the air entering the air exchange box 1, and then sends it into the silkworm rearing room through the exhaust port 4, so that the temperature in the silkworm rearing room is maintained within the appropriate range.

[0030] By controlling the concentration of carbon dioxide and temperature, the problem of sudden temperature drops caused by simple ventilation is avoided, ensuring the stability of temperature and humidity in the silkworm rearing room; the heating components enhance the equipment's adaptability to different environmental conditions, which is more conducive to the growth and development of silkworms.

[0031] According to one embodiment of this utility model, the ventilation mechanism further includes a filter screen, which is fixedly installed at the input port of the fan. When the fan is working, outside air is first filtered by the filter screen to remove dust, impurities, and other harmful substances from the air, and then enters the ventilation box 1 through the ventilation pipe, and finally is sent into the silkworm house. The filter screen effectively purifies the air entering the silkworm house, preventing dust and impurities from harming the silkworms and reducing the probability of silkworm diseases; at the same time, it protects the fan and internal components of the equipment, extends the service life of the equipment, and reduces maintenance costs.

[0032] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
