Description

Technical Field

[0001] The present invention relates to the technical field of animal husbandry farms, and in particular to an intelligent monitoring device for harmful gases in animal husbandry farms. Background Art

[0002] Livestock farms refer to places dedicated to the breeding and reproduction of livestock and poultry. These farms usually include areas for the breeding of cattle, sheep, pigs, chickens, ducks and other livestock and poultry, as well as related feed storage, breeding facilities, sanitary facilities, veterinary health facilities, etc. The size of farms varies, some may be small family farms, while others may be large-scale farms.

[0003] In existing animal husbandry farms, livestock and poultry will produce a large amount of feces and urine, which will decompose harmful gases and pollute the environment. At the same time, a large amount of harmful gases will accumulate and affect livestock and poultry. When monitoring harmful gases in large outdoor farms, the existing detection device is fixed in one area and can only monitor the harmful gases in this area, but cannot monitor other areas, resulting in limitations. When it is necessary to monitor other areas, it is necessary to set up multiple monitoring points or manually use monitoring equipment to move to the corresponding positions regularly to detect harmful gases to complete the monitoring work, which increases time costs. It is not enough to sample the surrounding areas of the water area, but the existing detection device cannot sample and detect at different heights, which affects the accuracy of the regional monitoring results. Manual operation may cause sampling errors, affecting the accuracy of the monitoring results. In addition, due to limitations in manpower and material resources, it is difficult for traditional sampling devices to achieve continuous and automatic monitoring of different areas and heights, and it is impossible to comprehensively track the concentration of harmful gases.

After the bottle mouth of the detection bottle 72 receives pressure, the sealing baffle 74 of the bottle mouth is squeezed down and squeezes the tower spring 75, and the collected gas enters the detection bottle 72 through the air inlet of the detection bottle 72, and the gas in the next collection tube is switched to enter the next detection bottle 72, and the gas in the detection bottle 72 is sucked out by the suction pump 9 to remove the air in the detection bottle 72; After the lifting hydraulic cylinder 7 drives the fixing frame 71 to descend, the sealing door plate 81 is reset under the action of the tension spring 82, and the sensor group 76 detects the concentration of harmful gases in the collected gas. After the detection is completed, the gas in the detection bottle 72 is sucked into the collection tank 92 by the suction pump 9, filtered by the filter assembly 93, and then discharged through the outlet pipe; When it is necessary to clean the collection tube and the detection bottle 72, the hydraulic cylinder 24 is pushed to push the adsorption electromagnet 25 to adsorb to the base of the drone 11, and the drone 11 is pulled to move a set distance. After the supporting hydraulic cylinder 10 rises and the sealing door panel 81 is pushed open, the cleaning tank 101 is sleeved on the outside of the collection tube 31, and the piston 32 is pushed to suck the cleaning liquid in the cleaning tank 101. Then, the hydraulic cylinder 24 is pushed to push the drone 11 to reset. After the detection bottle 72 rises, the collection tube 31 can transport the cleaning liquid into the detection bottle 72 for cleaning under the push of the piston 32. After cleaning, it is sucked by the suction pump 9 and then transported into the collection tank 92 for filtration and discharge. The drone 11 can be charged by plugging the charging port 23 on the drone 11 with the charging base 22.
