Description

Technical Field

[0001] This invention relates to the field of air monitoring technology in livestock and poultry farming, specifically a continuous sampling device for air monitoring in large-scale chicken farms. Background Technology

[0002] In large-scale egg and broiler farming, chicken excrement in chicken houses continuously decomposes, producing irritating and harmful gases such as ammonia, hydrogen sulfide, and carbon dioxide. At the same time, it is accompanied by a large amount of dust and microbial aerosols. Excessive concentration of harmful gases can damage the chickens' respiratory tract, reduce egg production / weight gain efficiency, and pollute the air around the farm. Environmental protection supervision requires routine sampling and testing of the air in each chicken house and the front / middle / back sections of the chicken house.

[0003] Currently available conventional air sampling devices have limited functionality, supporting only single-point sampling. A single device cannot continuously collect air data from multiple chicken houses or different breeding areas within the same chicken house. Staff need to carry multiple sampling devices to and from each chicken house, resulting in time-consuming sampling, low work efficiency, and easy confusion between different batches of sampling containers. This makes it difficult to simultaneously compare exhaust gas data from multiple chicken houses, hindering real-time environmental management in chicken farms. Therefore, structural improvements are needed to address these pain points in the breeding scenario. Summary of the Invention

[0004] The purpose of this invention is to provide a continuous sampling device for air monitoring in large-scale chicken farms, which solves the problems of existing sampling equipment being unable to continuously sample multiple chicken houses and multiple breeding zones in a chicken farm, and single equipment being able to collect exhaust gas at a single point at a time, resulting in low efficiency in air monitoring operations in the breeding environment.

[0005] This invention provides the following technical solution: a continuous sampling device for air monitoring in a large-scale chicken farm, comprising a sampling cylinder, an mounting plate installed at one end of the sampling cylinder, and a screw threadedly connected inside the mounting plate. A magnet is mounted on the bottom end of the screw thread via a bearing. A movable rod is movably arranged inside the sampling cylinder, and a disc is installed at one end of the movable rod. A sealing ring is fitted on the outer surface of the disc. An mounting plate is installed at the other end of the movable rod, and a hand-held lever is installed on one side of the mounting plate. Four sets of threaded posts are installed on the bottom of the outer surface of the sampling cylinder, and a connecting cylinder is movably screwed inside each of the four sets of threaded posts. A vacuum bottle is connected to the bottom of each of the four sets of connecting cylinders, and a one-way valve is installed on one side of the outer surface of each of the four sets of connecting cylinders.

[0006] Preferably, a through hole is provided on one side of the inner wall of the sampling tube near one end of the movable rod, and one end of the movable rod passes through the through hole and penetrates the inner wall of one side of the sampling tube.

[0007] Preferably, the magnet is arc-shaped and positioned directly above the movable rod.

[0008] Preferably, the interior of each of the four sets of threaded posts is hollow, and each of the four sets of threaded posts is connected to the interior of the sampling cylinder.

[0009] Preferably, the four sets of vacuum bottles are of equal size, and the four sets of vacuum bottles are respectively connected to the corresponding threaded columns through corresponding connecting cylinders. Beneficial effects

[0010] Compared with the prior art, the beneficial effects of the present invention are: By combining components such as sampling cylinders, threaded columns, movable rods, discs, sealing rings, mounting plates, handheld rods, connecting cylinders, vacuum bottles, and one-way valves, this device is suitable for large-scale chicken farm exhaust gas monitoring scenarios. A single unit can continuously sample air from multiple chicken houses or different breeding zones within the same chicken house. It avoids the limitation of traditional sampling devices that can only collect exhaust gas from a single point at a time, eliminating the need to carry multiple sets of sampling equipment, significantly reducing the time spent by chicken farm environmental monitoring personnel traveling between chicken houses, and improving the efficiency of air sampling in chicken farms. Four independent vacuum bottles can separately seal exhaust gas samples from different chicken houses / zones, preventing cross-contamination of samples. This facilitates simultaneous laboratory testing of multiple indicators such as ammonia, hydrogen sulfide, and dust, allowing farms to compare air quality in different areas and adjust ventilation and manure removal processes in a timely manner to ensure that the chicken farming environment meets standards.

[0015] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0016] Please refer to Figures 1 to 3. The present invention provides a technical solution: a continuous sampling device for air monitoring in a large-scale chicken farm, including a sampling cylinder 1. The sampling cylinder 1 is made of transparent material, and the interior of the sampling cylinder 1 can be seen from the outside. An mounting plate 11 is installed at one end of the sampling cylinder 1, and a screw 12 is movably screwed into the interior of the mounting plate 11. A magnet 13 is installed at the bottom end of the screw 12 through a bearing. The magnet 13 is arc-shaped and is positioned directly above the movable rod 2. In the initial state, the bottom surface of the magnet 13 will be attached to the outer surface of the movable rod 2 and be adsorbed and fixed accordingly.

[0017] The sampling cylinder 1 has a movable rod 2 inside, and a disc 21 is installed at one end of the movable rod 2. A through hole is opened on one side of the inner wall of the sampling cylinder 1 near one end of the movable rod 2, and one end of the movable rod 2 passes through the through hole and is connected to one side of the inner wall of the sampling cylinder 1. A sealing ring 22 is fitted on the outer surface of the disc 21. The outer surface of the sealing ring 22 is fitted to the inner wall of the sampling cylinder 1, so that the sealing ring 22 can play a sealing role, thereby preventing the exhaust gas from the chicken house from flowing into the space behind the disc 21. An installation plate 23 is installed at the other end of the movable rod 2, and a hand handle 24 is installed on one side of the installation plate 23. Four sets of threaded columns 14 are installed on the outer surface of the sampling cylinder 1 near the bottom, and a connecting cylinder 3 is movably screwed into the interior of each of the four sets of threaded columns 14. The interior of each of the four sets of threaded columns 14 is hollow, and each of the four sets of threaded columns 14 is connected to the interior of the sampling cylinder 1.

[0018] The bottom ends of the four sets of connecting cylinders 3 are all connected to vacuum bottles 31, and one-way valves 32 are installed on one side of the outer surface of the four sets of connecting cylinders 3. The four sets of vacuum bottles 31 are of equal size, and the four sets of vacuum bottles 31 are connected to the corresponding threaded post 14 through the corresponding connecting cylinder 3.

[0019] In use, the monitoring personnel can move the sampling cylinder 1 into the No. 1 chicken house, and then rotate the screw 12 accordingly, so that the magnet 13 can move upward, thereby separating the magnet 13 from the outer surface of the movable rod 2. At this time, the mounting plate 23 can be moved away from the sampling cylinder 1 by holding the handle 24, so that the movable rod 2, the disc 21, and the sealing ring 22 can move accordingly. When the disc 21 moves to the left of the leftmost threaded post 14 shown in Figure 1, the movement of the movable rod 2 can be stopped. Then, by rotating the screw 12, the magnet 13 can be attracted and fixed to the outer surface of the movable rod 2. At this time, the one-way air valve 32 on the outer surface of the connecting cylinder 3, which is screwed to the corresponding threaded post 14, can be opened, so that the breeding waste gas in the No. 1 chicken house can be injected into the connecting cylinder 3 and the vacuum bottle 31 through the sampling cylinder 1 and the corresponding threaded post 14. The air is collected inside the chicken house and then the connecting tube 3 is closed through the one-way air valve 32. Similarly, the air is sampled in the same way for the second, third and fourth chicken houses (or the front, middle and rear three breeding zones of the same chicken house + the air outlet of the factory area). This enables continuous sampling of exhaust gas from different breeding areas of the chicken farm, thereby greatly improving the efficiency of air monitoring and sampling in the chicken farm.

[0020] After the four sets of vacuum bottles 31 collect exhaust gas samples from different chicken houses / breeding zones, the four sets of vacuum bottles 31 can be rotated accordingly, so that the four sets of connecting cylinders 3 can be separated from the corresponding threaded columns 14. The four sets of vacuum bottles 31 can then be sent to the laboratory to test the concentration of ammonia, hydrogen sulfide, carbon dioxide, and dust in the exhaust gas inside the bottles. Based on the test data, the ventilation equipment and manure cleaning cycle of the chicken house can be adjusted to ensure that the gas indicators of the chicken house meet the environmental protection standards for livestock and poultry farming and the requirements for healthy livestock and poultry farming.

[0021] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
