Description

Technical Field

[0001] The present invention relates to the technical field of temperature and humidity monitoring, and in particular to a temperature and humidity monitoring device for animal husbandry based on the Internet of Things. Background Art

[0002] The temperature and humidity monitoring device can monitor the temperature and humidity of the environment. For example, in large-scale animal husbandry, for the convenience of management, livestock are often raised in pens, and the entire growth cycle of livestock is in the pens. Since the pens of farms are usually semi-enclosed structures, good temperature and humidity conditions in the pens have a certain promoting effect on the growth of livestock, and can improve the immunity of livestock and poultry and reduce the occurrence of diseases. Temperature and humidity monitoring devices are particularly important in monitoring the livestock breeding environment. The development of the Internet of Things enables monitoring devices to be interconnected, further improving the convenience of monitoring the livestock breeding environment, and playing an important role in modern livestock breeding.

[0003] Prior art, such as the Chinese patent "CN212674203U", provides a livestock breeding environment monitoring device, including a host, a display, a gas content monitoring module, a temperature and humidity monitoring module, and a light intensity monitoring module. Among them, the host and the display are installed in the monitoring room, and the gas content monitoring module, the temperature and humidity monitoring module, and the light intensity monitoring module are installed in the pen. The gas content monitoring module includes a carbon dioxide sensor, an ammonia sensor, and a hydrogen sulfide sensor. The temperature and humidity monitoring module includes a temperature and humidity sensor, and the light intensity monitoring module includes an illumination sensor. The single-chip microcomputer in the host receives digital signals from the carbon dioxide sensor, the ammonia sensor, the hydrogen sulfide sensor, the temperature and humidity sensor, and the illumination sensor. The single-chip microcomputer can compare the monitoring information with the standard value and display the comparison results on the display. In this way, the environment of the breeding pen can be intuitively understood, and targeted and timely adjustments can be made.

[0004] When the temperature and humidity sensor is in use, the probe surface should be kept clean to avoid dust, dirt, grease and other pollutants adhering to it, so as to prevent these substances from polluting or damaging the probe, and at the same time ensure the accuracy of the measurement. Usually, a clean soft cloth or cotton swab is used to gently wipe the probe surface to remove pollution, or a filter is used to filter the air to block dirt. However, long-term use of the filter surface will also cause dust accumulation and blockage, and it also needs to be cleaned or replaced. Therefore, whether manual wiping or filter blocking is used, manual operation is required regularly, which leads to a large amount of manpower investment in later maintenance. In addition, in the livestock breeding environment, the activities of the animals themselves will generate certain air pollution, such as dust raised by animal activities. Therefore, a temperature and humidity monitoring device for livestock breeding based on the Internet of Things is proposed. Summary of the invention

[0037] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0038] See also Figure 1 - Figure 8 As shown, the present invention provides a temperature and humidity monitoring device for animal husbandry based on the Internet of Things, including a temperature and humidity sensor 1, a mounting plate 2 is fixedly connected to the back of the temperature and humidity sensor 1, and a signal transmitter and receiver 3 is fixedly connected to the side of the temperature and humidity sensor 1. Wi-Fi is used for signal transmission to realize wireless communication with other devices (such as mobile phones, tablet computers, servers, etc.), and the temperature and humidity data are transmitted to a remote terminal for monitoring and analysis, so as to cooperate with the control components inside the temperature and humidity sensor 1 for operation. The left side of the bottom of the temperature and humidity sensor 1 is fixedly connected with an integrated sensing probe 8 (reference Figure 1 , Figure 2), the integrated sensing probe 8 is used to detect the temperature and humidity in the environment, and convert the changes in temperature and humidity into electrical signals for subsequent processing and transmission. A filter sleeve 7 is provided on the outside of the integrated sensing probe 8 to filter dust, impurities, etc. in the air.

[0039] In this embodiment, please refer to Figure 2 , Figure 3 , Figure 4 , Figure 5 The switching mechanism includes a base 4, which is fixedly connected to the bottom of the temperature and humidity sensor 1. A switching ring 5 is attached to the bottom of the base 4. Four circular holes 6 are opened on the inner wall of the switching ring 5, which are distributed in a circular array. The integrated sensing probe 8 extends through the through hole opened in the base 4 to the inside of the circular hole 6 at the corresponding position below. There are four groups of filter sleeves 7, and the four groups of filter sleeves 7 are respectively fixedly connected to the bottom of the switching ring 5 at the position of each circular hole 6. By arranging multiple groups of filter sleeves 7 at the bottom of the switching ring 5, a new filter sleeve 7 can be switched by rotating the switching ring 5 for filtering, so as to avoid the problem that dust accumulation on the surface of the filter sleeve 7 causes blockage due to long-term use, affecting the normal circulation of air, and causing the detection accuracy of the integrated sensing probe 8 to decrease. The bottom of the base 4 is at a position outside the integrated sensing probe 8. The limiting cylinder 9 is fixedly connected, and the limiting cylinder 9 is slidably connected to the inner wall of the circular hole 6 at the corresponding position. The limiting cylinder 9 is in a hollow setting in the sensing area of ​​the integrated sensing probe 8 to avoid affecting the flow of air. The switching mechanism also includes a rotating rod 10, which is rotatably connected to the center of the bottom circle of the base 4. The outer wall of the rotating rod 10 is coaxially sleeved with a sleeve 11, and the bottom of the sleeve 11 is fixedly connected to the switching ring 5 through a connecting frame 12. A spiral limiting groove 13 is opened on the outer wall of the sleeve 11, and the rotation angle of the spiral is one hundred and eighty degrees. The outer wall of the rotating rod 10 is fixedly connected to a limiting block 14, and the limiting block 14 is slidably connected to the inner wall of the limiting groove 13. When the switching ring 5 and the base 4 are in a fitted state, the limiting block 14 is at the bottom of the limiting groove 13. When the rotating rod 10 rotates clockwise (reference Figure 3 , Figure 5), since the limiting cylinder 9 at the bottom of the base 4 is inserted into the circular hole 6 on the switching ring 5, the switching ring 5 is limited in radial rotation, so that when the rotating rod 10 rotates, the limiting block 14 connected to the outer wall will abut against the spiral limiting groove 13 on the outer wall of the sleeve 11, forcing the sleeve 11 to make radial linear motion, thereby driving the switching ring 5 connected to the connecting frame 12 to descend. When the rotating rod 10 rotates to 180 degrees, the limiting block 14 just abuts against the top of the limiting groove 13, and the limiting cylinder 9 is separated from the circular hole 6, releasing the radial rotation of the switching ring 5 The limit position makes the rotating rod 10 continue to rotate 90 degrees, just driving the new limit cylinder 9 to move to the integrated sensing probe 8 for switching. The top of the outer wall of the rotating rod 10 is fixedly sleeved with a first gear 15, and the outer wall of the first gear 15 is meshed with a second gear 16. The transmission ratio of the second gear 16 is consistent with that of the first gear 15. The bottom of the base 4 is fixedly connected with a servo motor 17 for driving the second gear 16 to rotate. By starting the servo motor 17, the second gear 16 is driven to rotate counterclockwise by 270 degrees (reference Figure 2 ), through the meshing first gear 15, the rotating rod 10 is conveniently driven to rotate two hundred and seventy degrees clockwise.

[0040] For further information, see Figure 3 , Figure 6 The cleaning structure includes a slide rail 20, which is fixedly sleeved on the outer wall of the switching ring 5. The outer wall of the slide rail 20 is slidably connected with a ball sleeve 19. The bottom of the ball sleeve 19 is fixedly connected with a bracket 21. The bracket 21 extends to the corresponding position below the filter sleeve 7. The bracket 21 is located below the filter sleeve 7 and is rotatably connected with a cleaning brush 22 through a rotating shaft. The cleaning brush 22 contacts the surface of the filter sleeve 7. The rotating shaft is coaxial with the filter sleeve 7. Through the rotation of the cleaning brush 22, the surface of the filter sleeve 7 can be fully cleaned for recycling. The cleaning structure also includes a ball screw 18, which is rotatably connected to the bottom of the base 4 at the front of the switching ring 5. The outer wall of the ball screw 18 is threadedly connected to the ball sleeve 19 The bottom of the rotating shaft connected to the bottom of the ball screw 18 and the cleaning brush 22 is fixedly connected with a synchronous wheel 23, and the two synchronous wheels 23 are connected through a synchronous belt 24. When the switching ring 5 descends, the switching ring 5 will drive the ball sleeve 19 sliding on the outer wall of the slide rail 20 to descend together. At the same time, the ball sleeve 19 will undergo radial displacement on the outer wall 18 of the ball screw, thereby forcing the ball screw 18 rotatably connected to the base 4 to rotate. When the ball screw 18 rotates, it will drive a synchronous wheel 23 at the bottom of the ball screw 18 to rotate, and drive another synchronous wheel 23 through the synchronous belt 24, so that the cleaning brush 22 on the rotating shaft connected to the other synchronous wheel 23 rotates, so as to facilitate the cleaning of the surface of the filter sleeve 7 at the current position.

[0041] For further information, see Figure 3 , Figure 4 , Figure 6 The cleaning structure also includes an air chamber 26, which is fixedly connected to the inner wall of the switching ring 5. Four air outlet holes 27 are provided on the top of the air chamber 26, and the positions of the four air outlet holes 27 and the four circular holes 6 correspond one to one. An air duct 30 is provided on the inner wall of the base 4 between the air outlet holes 27 on the front of the air chamber 26 and the circular holes 6 at the corresponding positions, for connecting the air outlet holes 27 at the corresponding positions with the circular holes 6. By providing the air duct 30, the air outlet holes 27 on the air chamber 26 can be connected with the circular holes 6 at the corresponding positions, so that when the air chamber 26 is squeezed, the air inside the air chamber 26 will be squeezed from the air outlet holes 27 into the air duct 30 and sprayed into the circular holes 6. An airflow is formed and can eventually be ejected from the filter sleeve 7 from the inside to the outside. The ejected airflow can cooperate with the cleaning brush 22 to further improve the cleaning effect of the dirt on the surface of the filter sleeve 7, and the ejected airflow can also remove the dirt attached to the cleaning brush 22, which is beneficial for the cleaning brush 22 to improve the cleaning effect. The cleaning structure also includes an extrusion ring 25, which is fixedly connected to the bottom of the base 4, and the extrusion ring 25 extends to the bottom of the air chamber 26. When the switching ring 5 descends, the switching ring 5 will drive the air chamber 26 connected to the inner wall to descend together. Since the extrusion ring 25 at the bottom of the base 4 is limited, the air chamber 26 will be squeezed with the extrusion ring 25 when it descends.

[0042] Also, see Figure 3 , Figure 4 , Figure 7 , multiple groups of springs 29 are fixedly connected to the inner wall of the air chamber 26. By arranging the springs 29 inside the air chamber 26, after the servo motor 17 completes a 270-degree rotation and stops power output, the tension of the springs 29 pushes the air chamber 26 to reset, and due to the limitation of the extrusion ring 25, the switching ring 5 connected to the air chamber 26 will be lifted and fit the base 4, and in this process, the ball sleeve 19 and the ball screw 18 and the limiting cylinder 9 and the rotating rod 10 will also reset together. Multiple air inlet holes 28 are opened at the bottom of the air chamber 26, and the inner walls of the air inlet hole 28 and the air outlet hole 27 are both provided with one-way valves. The one-way valves can prevent the air at the air inlet hole 28 and the air outlet hole 27 from backflowing, so that the air can only enter the air chamber 26 from the air inlet hole 28 and be discharged from the air outlet hole 27.

[0043] In addition, see Figure 2 , Figure 8The storage mechanism includes a protective shell 31, which is magnetically adsorbed on the bottom of the switching ring 5, and the protective shell 31 is wrapped around the outside of the two filter sleeves 7 outside the integrated sensing probe 8 and the cleaning position. The protective shell 31 is fixedly connected to the bottom of the base 4 through a telescopic plate 32, and both ends of the protective shell 31 are respectively hinged with a cover 33, and a torsion spring for resetting is provided at the hinge of the cover 33. By arranging the cooperation between the protective shell 31 and the cover 33, other filter sleeves 7 except the filter sleeve 7 being used and the filter sleeve 7 to be cleaned can be stored in the protective shell. The inside of the protective shell 31 is protected to avoid pollution. The bottom of the switching ring 5 is fixedly connected to one side of each filter sleeve 7 with a push block 34 for pushing the cover 33 to open. Each time the switching ring 5 rotates to switch the filter sleeve 7, the switching ring 5 will drive the cleaned filter sleeve 7 to move into the protective shell 31 for protection. During the movement, the push block 34 will preferentially contact the cover 33 to push it open. After the filter sleeve 7 completely enters the protective shell 31, the push block 34 disengages from the cover 33 to release the limit, and the elastic force of the torsion spring drives the cover 33 to rotate and reset, thereby sealing the protective shell 31.

[0044] How it works

[0045] When in use, the servo motor 17 is started to drive the second gear 16 to rotate counterclockwise by 270 degrees. Figure 2 , through the meshing first gear 15 to facilitate the rotation of the rotating rod 10 clockwise rotation of 270 degrees, when the rotating rod 10 rotates clockwise reference Figure 3 , Figure 5Since the limiting cylinder 9 at the bottom of the base 4 is inserted into the circular hole 6 on the switching ring 5, a radial rotation limit is formed for the switching ring 5, so that when the rotating rod 10 rotates, the limiting block 14 connected to the outer wall will abut against the spiral limiting groove 13 on the outer wall of the sleeve 11, forcing the sleeve 11 to make a radial linear motion, thereby driving the switching ring 5 connected to the connecting frame 12 to descend. When the rotating rod 10 rotates to 180 degrees, the limiting block 14 just abuts against the top of the limiting groove 13, and the limiting cylinder 9 disengages from the circular hole 6, releasing the radial rotation limit of the switching ring 5, so that after the rotating rod 10 continues to rotate 90 degrees, it just drives the new limiting cylinder 9 to move to the integrated sensing probe 8 for switching, and when the switching ring 5 descends, the switching ring 5 will drive the ball sleeve 19 sliding on the outer wall of the slide rail 20 to move. When the switching ring 5 descends, the switching ring 5 will drive the air chamber 26 connected to the inner wall to descend together. Due to the limit of the extrusion ring 25 at the bottom of the base 4, the air chamber 26 will be squeezed with the extrusion ring 25 when it descends. By setting the air duct 30, the air outlet 27 on the air chamber 26 can be The filter sleeve 7 is connected to the circular hole 6 at the position, so that when the air chamber 26 is squeezed, the air inside the air chamber 26 will be squeezed into the air passage 30 from the air outlet 27 and sprayed into the circular hole 6 to form an airflow, and finally can be sprayed out from the filter sleeve 7 from the inside to the outside. The sprayed airflow can cooperate with the cleaning brush 22 to further improve the cleaning effect of the dirt on the surface of the filter sleeve 7, and the sprayed airflow can also remove the dirt attached to the cleaning brush 22, which is beneficial to the cleaning effect of the cleaning brush 22. By setting the tension of the spring 29 inside the air chamber 26, the air chamber 26 can be pushed to reset after the servo motor 17 stops outputting power at 270 degrees, and due to the limitation of the extrusion ring 25, the switching ring 5 connected to the air chamber 26 will be lifted and fit the base 4. In this process, the rolling The ball sleeve 19, the ball screw 18, the limiting cylinder 9 and the rotating rod 10 will also be reset together. By arranging a spring 29 inside the air chamber 26, after the servo motor 17 completes a 270-degree rotation and stops power output, the tension of the spring 29 pushes the air chamber 26 to reset. Due to the limitation of the extrusion ring 25, the switching ring 5 connected to the air chamber 26 will be lifted and fit the base 4. In this process, the ball sleeve 19, the ball screw 18, the limiting cylinder 9 and the rotating rod 10 and all the parts connected or transmitted by them will also be reset together. Every time the switching ring 5 rotates to switch the filter sleeve 7, the switching ring 5 will drive the cleaned filter sleeve 7 to move into the protective shell 31 for protection. During the movement, the push block 34 will preferentially contact the sealing cover 33 to push it open.After the filter sleeve 7 completely enters the protective shell 31, the push block 34 is separated from the sealing cover 33 to release the limit, and the elastic force of the torsion spring drives the sealing cover 33 to rotate and reset, thereby sealing the protective shell 31.

[0046] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
