Abstract

The application discloses a wearable methane breathing filtering device for a dairy cow, and belongs to the field of methane filtering devices. The device can detect methane gas generated by the dairy cow when burping or breathing. When the methane gas is excessive, the methane gas is transmitted to a reaction area for a reduction reaction to generate carbon dioxide and water, so that the methane gas is filtered and purified, the effect of reducing methane emission is achieved, and the product after the purified methane is discharged in the next absorption process of the methane gas, so that the value of the greenhouse effect caused by the methane emission is reduced. Meanwhile, the data of the methane gas is recorded every time the methane gas is detected, the data of the methane emitted by the dairy cow is recorded, and the feeding efficiency and the physical condition of the dairy cow are compared with the data, so that it is determined that the content of the methane generated by the dairy cow is increased due to a certain condition. Corresponding measures are taken in the later period, so that the health condition of the dairy cow is ensured.

Description

Technical Field

[0001] This invention relates to the field of methane filtration equipment, and more specifically, to a wearable methane breathing filtration device for dairy cows. Background Technology

[0002] Methane is essentially non-toxic to humans, but when its concentration is too high, it significantly reduces the oxygen content in the air, causing suffocation. When the methane concentration in the air reaches 25%-30%, it can cause headaches, dizziness, fatigue, difficulty concentrating, rapid breathing and heartbeat, ataxia, and it also increases the greenhouse effect.

[0003] Currently, cows exhale large amounts of methane gas during breathing and burping. If the methane emissions from cows on farms are too high, it will increase the greenhouse effect and affect the ecological environment. Furthermore, excessive methane exhalation by cows may indicate health problems. Therefore, there is an urgent need for a respiratory filtration device that can filter the methane gas exhaled by cows and diagnose their health status based on the methane gas they exhale. Summary of the Invention

[0004] 1. Technical problems to be solved

[0005] To address the problems existing in the prior art, the present invention aims to provide a wearable methane respiratory filtration device for dairy cows. This device detects methane gas produced when a cow burps or breathes. If the methane content is not excessive, the absorbed gas is released. If the absorbed methane content is excessive, the methane gas is transferred to a reaction zone for reduction, generating carbon dioxide and water to filter and purify the methane gas, thus reducing methane emissions. Subsequently, when the device absorbs methane exhaled by the cow again, if the secondary methane content is not within acceptable limits, the excess methane gas and the purified methane byproducts are simultaneously discharged, thereby reducing the greenhouse effect caused by methane emissions. The device records the methane data from each detection and compares it with the cow's feeding efficiency and physical condition to determine the cause of increased methane levels. This allows for subsequent appropriate measures to be taken, ensuring the cow's health and reducing farm expenses.

[0006] 2. Technical Solution

[0007] To solve the above problems, the present invention adopts the following technical solution.

[0008] A wearable methane respiration filtration device for dairy cows includes a cow body with a respiration filtration device attached to its outer end. A buckle is fitted onto the outer end of the cow body, and the buckle is fixedly connected to the respiration filtration device. A gas guide rod is installed on the outer end of the respiration filtration device, and a solar cell is installed on its upper end. This design allows the respiration filtration device to be worn near the cow's nose and mouth via the buckle. When the cow burps or breathes, the methane gas produced is absorbed by the gas guide rod and transported to the respiration filtration device for methane detection. If the methane gas content is not excessive, a second closing component is controlled to open and close, releasing the absorbed gas. If the absorbed methane gas content is excessive, a first closing component is controlled to open and close, and under the action of a fan component, the excessive methane gas is adsorbed into the filter box above the solid catalyst, which can be referred to as the reaction zone. Subsequently, the system... When the first closed component closes again, the fan component stops working. The solid catalyst inside the reaction zone reduces the adsorbed excessive methane gas, producing carbon dioxide and water, which then filter and purify the methane gas, reducing methane emissions. Subsequently, if the methane levels are below standard during the next adsorption of methane exhaled by the cows, the second and third closed components open and close simultaneously. This causes the second-absorbed methane gas and the products of purifying excessive methane to be released from the respiratory filtration equipment, thus reducing the greenhouse effect caused by methane emissions. Simultaneously, data on methane emissions is recorded each time, and this data is compared with the cows' feeding efficiency and physical condition to determine the cause of increased methane levels. This allows for subsequent appropriate measures to be taken, ensuring the cows' health and reducing farm expenses.

[0009] Furthermore, the breathing filtration device includes a filter box fixedly connected to the outer end of a snap fastener. A partition is fixedly connected between the inner walls of the filter box. A vent hole is drilled at the outer end of the partition. A first closing component and a fan component are provided between the inner walls of the vent hole. An air inlet channel is drilled in the inner wall of the filter box, and the air inlet channel is connected to a gas guide rod. A gas detection sensor is installed on the upper inner wall of the filter box. A second closing component is installed on the inner wall of the filter box on the side away from the air inlet channel. A third closing component is provided on the lower inner wall of the filter box. A solid catalyst is provided at the bottom of the filter box located between the partition and the inner wall of the third closing component. In this scheme, when the cow burps or breathes, the methane gas it produces is absorbed by the gas guide rod and transmitted to the inside of the filter box for methane gas detection. If the methane gas is not excessive, the second closing component is controlled to open and close, transferring the absorbed gas... The system releases methane gas. When the absorbed methane gas content is excessive, the first closing component is controlled to open and close. Under the action of the fan component, the excessive methane gas is adsorbed into the filter box above the solid catalyst, which can be called the reaction zone. Then, the first closing component is controlled to close again, the fan component stops working, and the solid catalyst inside the reaction zone reduces the adsorbed excessive methane gas to produce carbon dioxide and water, thus filtering and purifying the methane gas and reducing methane emissions. Subsequently, when adsorbing methane gas exhaled by the cows again, if the secondary methane content is not up to standard, the second and third closing components are controlled to open and close simultaneously, causing the secondary absorbed methane gas and the products of purifying excessive methane to be released into the respiratory filtration equipment, thereby reducing the greenhouse effect caused by methane emissions.

[0010] Furthermore, the first closing component includes a first groove carved inside the partition, the first groove penetrating the inner wall of the vent hole, and a first control switch sensor installed on both the left and right inner walls of the first groove. The outer end of the first control switch sensor is electrically connected to a first telescopic rod, and the ends of the first telescopic rod that are close to each other are fixedly connected to a first sealing plate. The diameter of the first sealing plate is equal to 1 / 2 the diameter of the vent hole. When the cow exhales excessive methane gas, the gas detection sensor sends a signal to the first control switch sensor, causing the first control switch sensor and the fan assembly to start, causing the first telescopic rod to retract, which in turn causes the originally closed first sealing plate to separate. Subsequently, under the action of the fan assembly, the methane is adsorbed into the filter box above the solid catalyst, and the methane gas is filtered and purified.

[0011] Furthermore, the fan assembly includes four support columns fixedly connected between the inner walls of the vent holes. A fan control switch sensor is installed between the inner walls of the support columns. A fan base is installed at the outer end of the fan control switch sensor. A fan is rotatably connected to the outer end of the fan base. The fan is located on the side close to the third closed assembly. When the cow exhales excessive methane gas, the gas detection sensor sends a signal to the fan control switch sensor, causing the fan control switch sensor to start and drive the fan base and fan to rotate, adsorbing the methane gas inside the air intake channel into the filter box on the side of the third closed assembly.

[0012] Furthermore, the second closing assembly includes a first air outlet hole carved into the inner wall of the filter box on the side away from the air inlet channel. A second sliding groove is carved into the inside of the filter box, penetrating the inner wall of the first air outlet hole. A second control switch sensor is installed on both the left and right inner walls of the second sliding groove. A second telescopic rod is electrically connected to the outer end of the second control switch sensor. A second sealing plate is fixedly connected to the end of the second telescopic rod that is close to each other. The diameter of the second sealing plate is equal to 1 / 2 the diameter of the first air outlet hole. When the methane gas exhaled by the cow is not excessive, the gas detection sensor sends a signal to the second control switch sensor, causing the second control switch sensor to activate. This causes the second telescopic rod to retract, which in turn causes the originally closed second sealing plate to separate. Subsequently, under the action of airflow, the methane that is within the standard is discharged to the outside.

[0013] Furthermore, the third closing assembly includes a second air outlet carved into the inner wall of the filter box. A third sliding groove is carved inside the filter box, penetrating the inner wall of the second air outlet. A third control switch sensor is installed on both the left and right inner walls of the third sliding groove. A third telescopic rod is electrically connected to the outer end of the third control switch sensor. A third sealing plate is fixedly connected to the end of the third telescopic rod that is close to each other. The diameter of the third sealing plate is equal to 1 / 2 the diameter of the second air outlet. When the methane gas exhaled by the cow is not excessive, the gas detection sensor sends a signal to the third control switch sensor, causing the third control switch sensor to activate. This causes the third telescopic rod to retract, causing the originally closed third sealing plate to separate. Subsequently, under the action of airflow, the methane gas products that have been filtered and purified inside the reaction area are discharged to the outside, so that the methane gas can be purified again in the future.

[0014] Furthermore, the gas detection sensor includes a methane content detection module. The external end of the methane content detection module is electrically connected to a first control switch sensor, a fan control switch sensor, a second control switch sensor, and a third control switch sensor. The external end of the methane content detection module is electrically connected to a methane content data recording module, which includes an environmental parameter recording module and a time recording module. The external end of the methane content data recording module is electrically connected to a methane content data comparison module. The external end of the methane content data comparison module is electrically connected to an information generation module. The external end of the information generation module is electrically connected to a data transmission module. The external end of the data transmission module is electrically connected to a control terminal. When milk... After the gas exhaled by the cows is detected by a gas detection sensor, the sensor records the data. Simultaneously, the environmental parameter recording module and the time recording module record the methane content at that specific environmental and temporal conditions. This facilitates data comparison by staff later. The methane content data recording module then compares the data with a pre-programmed methane content data comparison module. For example, if the methane content falls within a certain range, it indicates potential changes in the cow's physical condition, such as reduced feed intake. This information is transmitted to the control terminal via the information generation and data transmission modules, alerting staff and enabling early diagnosis of the cows' health, thus protecting their well-being and reducing farm expenses.

[0015] Furthermore, the support column is made in the shape of an isosceles triangle, with the acute side located on the side of the gas detection sensor. By setting the support column to be in the shape of an isosceles triangle with the acute side located on the side of the gas detection sensor, the methane airflow driven by the fan can pass through the support column more smoothly during operation, making it less likely to cause obstruction of transmission efficiency.

[0016] 3. Beneficial effects

[0017] Compared with the prior art, the advantages of this invention are:

[0018] (1) In this scheme, when the cow burps or breathes, the methane gas it produces is absorbed by the gas guide rod and transported to the filter box for methane gas detection. If the methane gas is not excessive, the second closing component is controlled to open and close, releasing the absorbed gas. If the absorbed methane gas content is excessive, the first closing component is controlled to open and close, and the excessive methane gas is adsorbed into the filter box above the solid catalyst under the action of the fan component. This can be called the reaction zone. Then, the first closing component is controlled to close again, the fan component stops working, and the solid catalyst in the reaction zone reduces the adsorbed excessive methane gas to produce carbon dioxide and water, which filter and purify the methane gas, thereby reducing methane emissions. Subsequently, when the cow exhales methane gas again, if the secondary methane content is not up to standard, the second and third closing components are controlled to open and close simultaneously, causing the secondary absorbed methane gas and the products of purifying excessive methane to be released into the breathing filter, thereby reducing the greenhouse effect caused by methane emissions.

[0019] (2) In this scheme, after the gas exhaled by the cow is detected by the gas detection sensor, the gas detection sensor records the detected data. At the same time, the environmental parameter recording module and the time recording module record the methane content generated under the environmental conditions and time, which is convenient for the staff to compare the data later. Then, the methane content data recording module compares the data with the pre-set program in the methane content data comparison module. If the methane content value is in a certain range, the cow may experience certain physical changes, such as reduced feeding effect. This phenomenon is transmitted to the control terminal through the information generation module and the data transmission module to alert the staff, thereby making an early diagnosis of the cow's survival status, ensuring the health of the cow, and reducing the farm's expenses.

[0020] In summary, this solution allows for the detection of methane gas produced by cows during burping or breathing within a respiratory filtration device. If the methane gas level is within acceptable limits, the absorbed gas is released. If the absorbed methane gas level is excessive, it is transferred to a reaction zone for reduction, producing carbon dioxide and water to filter and purify the methane gas, thus reducing methane emissions. Subsequently, during the next methane absorption process, if the secondary methane level is below acceptable, the excess methane gas and the purified methane byproducts are simultaneously released, thereby reducing the greenhouse effect caused by methane emissions. Furthermore, the data from each methane gas detection is recorded, and the methane emissions from the cows are compared with their feeding efficiency and physical condition to determine the cause of increased methane levels. This allows for subsequent appropriate measures to be taken, ensuring the health of the cows and reducing farm expenses. Attached Figure Description

[0035] Example:

[0036] Please see Figure 1-9A wearable methane breathing filtration device for dairy cows includes a cow body 100, a breathing filtration device 200 at the outer end of the cow body 100, a buckle 300 fitted onto the outer end of the cow body 100, and a gas guide rod 400 installed at the outer end of the breathing filtration device 200. A solar cell 500 is installed on the upper end of the breathing filtration device 200. This design allows the breathing filtration device 200 to be worn at the cow's nose and mouth via the buckle 300, enabling the cow to breathe through the methane. During burping or breathing, the methane gas produced is absorbed by the gas guide rod 400 and transported to the breathing filter 200 for methane gas detection. If the methane gas content is not excessive, the second closing component 207 is controlled to open and close, releasing the absorbed gas. However, if the absorbed methane gas content is excessive, the first closing component 2021 is controlled to open and close, and under the action of the fan component 204, the excessive methane gas is adsorbed into the filter box 201 above the solid catalyst 209. Inside, this area can be called the reaction zone. The first closing component 2021 is then closed again, and the fan component 204 stops working. The solid catalyst 209 inside the reaction zone reduces the adsorbed excessive methane gas, producing carbon dioxide and water, thus filtering and purifying the methane gas and reducing methane emissions. Subsequently, if the secondary methane levels are below standard during the next adsorption of methane exhaled by the cows, the second and third closing components 207 and 208 are simultaneously opened and closed, causing the secondary adsorbed methane gas and the products of purified excessive methane to be released from the respiratory filtration device 200. This reduces the greenhouse effect caused by methane emissions. Simultaneously, data is recorded each time methane gas is detected, and the methane data emitted by the cows is compared with their feeding efficiency and physical condition to determine if increased methane levels are due to certain factors. This allows for subsequent appropriate measures to be taken, ensuring the health of the cows and reducing farm expenses.

[0037] Please see Figure 1-3The breathing filtration device 200 includes a filter box 201 fixedly connected to the outer end of a buckle 300. A partition 202 is fixedly connected between the inner walls of the filter box 201. A vent hole 203 is cut out at the outer end of the partition 202. A first closing component 2021 and a fan component 204 are provided between the inner walls of the vent hole 203. An air inlet channel 205 is cut out in the inner wall of the filter box 201. The air inlet channel 205 is connected to a gas guide rod 400. A gas detection sensor 206 is installed on the inner wall of the filter box 201. A second closing component 207 is installed on the inner wall of the side away from the air intake channel 205. A third closing component 208 is provided on the lower inner wall of the filter box 201. A solid catalyst 209 is provided at the bottom of the filter box 201 located between the partition 202 and the inner wall of the third closing component 208. In this scheme, when the cow burps or breathes, the methane gas it produces is absorbed by the gas guide rod 400 and transmitted to the inside of the filter box 201 for methane gas detection. If the methane gas is not excessive, the second closing component 207 is controlled. When the methane gas absorbed is excessive, the first closing component 2021 is controlled to open and close. Under the action of the fan component 204, the excessive methane gas is adsorbed into the filter box 201 above the solid catalyst 209. This area can be called the reaction zone. Then, the first closing component 2021 is controlled to close again, the fan component 204 stops working, and the solid catalyst 209 inside the reaction zone reduces the adsorbed excessive methane gas to produce carbon dioxide and water, thus filtering and purifying the methane gas and reducing methane emissions. Subsequently, when adsorbing methane gas exhaled by cows again, if the secondary methane level is not up to standard, the second closing component 207 and the third closing component 208 are controlled to open and close simultaneously, causing the secondary absorbed methane gas and the products of purifying excessive methane to be released into the respiratory filtration device 200, thereby reducing the greenhouse effect caused by methane emissions.

[0038] Please see Figure 2-5The first closing component 2021 includes a first groove 2022 carved inside the partition 202. The first groove 2022 penetrates the inner wall of the vent 203. A first control switch sensor 2023 is installed on both the left and right inner walls of the first groove 2022. The outer end of the first control switch sensor 2023 is electrically connected to a first telescopic rod 2024. The ends of the first telescopic rods 2024 that are close to each other are fixedly connected to a first sealing plate 2025. The diameter of the first sealing plate 2025 is equal to 1 / 2 the diameter of the vent 203. When the cow exhales excessive methane gas, the gas detection sensor 206 sends a signal to the first control switch sensor 2023, causing the first control switch sensor 2023 and the fan assembly 204 to start. This causes the first telescopic rod 2024 to retract, causing the originally closed first sealing plate 2025 to separate. Then, under the action of the fan assembly 204, the methane is adsorbed into the filter box 201 above the solid catalyst 209, and the methane gas is filtered and purified.

[0039] Please see Figure 2 and Figure 5-6 The fan assembly 204 includes four support columns 2041 fixedly connected between the inner walls of the vent 203. A fan control switch sensor 2042 is installed between the inner walls of the support columns 2041. A fan base 2043 is installed at the outer end of the fan control switch sensor 2042. A fan 2044 is rotatably connected to the outer end of the fan base 2043. The fan 2044 is located on the side close to the third closing assembly 208. When the cow exhales excessive methane gas, the gas detection sensor 206 sends a signal to the fan control switch sensor 2042, causing the fan control switch sensor 2042 to start and drive the fan base 2043 and the fan 2044 to rotate, thus adsorbing the methane gas inside the air intake channel 205 into the filter box 201 on the side of the third closing assembly 208.

[0040] Please see Figure 2-3 and Figure 7The second closing assembly 207 includes a first air outlet 2071 carved into the inner wall of the filter box 201 on the side away from the air inlet channel 205. A second sliding groove 2072 is carved into the inside of the filter box 201, penetrating the inner wall of the first air outlet 2071. Second control switch sensors 2073 are installed on both the left and right inner walls of the second sliding groove 2072. The outer ends of the second control switch sensors 2073 are electrically connected to second telescopic rods 2074. The ends of the second telescopic rods 2074 that are close to each other are fixedly connected to a second... The diameter of the second sealing plate 2075 is equal to half the diameter of the first vent 2071. When the methane gas exhaled by the cow is not excessive, the gas detection sensor 206 sends a signal to the second control switch sensor 2073, causing the second control switch sensor 2073 to be activated. This causes the second telescopic rod 2074 to retract, which in turn causes the originally closed second sealing plate 2075 to separate. Subsequently, under the action of airflow, the methane that is within the limit is discharged to the outside.

[0041] Please see Figure 2-3 and Figure 8 The third closing assembly 208 includes a second air outlet 2081 carved into the lower inner wall of the filter box 201. A third sliding groove 2082 is carved inside the filter box 201, penetrating the inner wall of the second air outlet 2081. Third control switch sensors 2083 are installed on both the left and right inner walls of the third sliding groove 2082. A third telescopic rod 2084 is electrically connected to the outer end of each third control switch sensor 2083. A third sealing plate 2085 is fixedly connected to one of the close ends of the third telescopic rods 2084. The diameter of the third sealing plate 2085 is... The size is equal to half the diameter of the second vent 2081. When the methane gas exhaled by the cow is not excessive, the gas detection sensor 206 sends a signal to the third control switch sensor 2083, causing the third control switch sensor 2083 to be activated. This causes the third telescopic rod 2084 to retract, which in turn causes the originally closed third sealing plate 2085 to separate. Then, under the action of airflow, the methane gas products that have been filtered and purified inside the reaction area are discharged to the outside, so that the methane gas can be purified again in the future.

[0042] Please see Figure 2 and Figure 9The gas detection sensor 206 includes a methane content detection module. The external ends of the methane content detection module are electrically connected to the first control switch sensor 2023, the fan control switch sensor 2042, the second control switch sensor 2073, and the third control switch sensor 2083, respectively. A methane content data recording module is electrically connected to the external end of the methane content detection module. The methane content data recording module includes an environmental parameter recording module and a time recording module. A methane content data comparison module is electrically connected to the external end of the methane content data comparison module. An information generation module is electrically connected to the external end of the information generation module. A data transmission module is electrically connected to the external end of the data transmission module. A control terminal is electrically connected to the external end of the gas sensor 206 when the cow exhales... After the gas is detected by the gas detection sensor 206, the sensor records the detected data. Simultaneously, the environmental parameter recording module and time recording module record the methane content under what environmental conditions and at what time, facilitating data comparison by staff later. The methane content data recording module then compares the data with a pre-set program in the methane content data comparison module. For example, when the methane content falls within a certain range, it indicates potential changes in the cow's physical condition, such as reduced feed intake. This information is transmitted to the control terminal via the information generation module and data transmission module, alerting staff and enabling early diagnosis of the cow's health, thus protecting the cow's well-being and reducing farm expenses.

[0043] Please see Figure 2 and Figure 6 The support column 2041 is made in the shape of an isosceles triangle, with the acute side located on one side of the gas detection sensor 206. By setting the support column 2041 in the shape of an isosceles triangle with the acute side located on one side of the gas detection sensor 206, the methane airflow driven by the fan 2044 can pass through the support column 2041 more smoothly during operation, and it is less likely to cause the phenomenon of obstructing the transmission efficiency.

[0044] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto; any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in the present invention, based on the technical solution and its improved concept, should be covered within the scope of protection of the present invention.

Then, the first closing component (2021) is closed again, the fan component (204) stops working, and the solid catalyst (209) inside the reaction zone reduces the methane gas that has been adsorbed into the excessive range, generating carbon dioxide and water, which filter and purify the methane gas, thereby reducing methane emissions. Then, when the methane gas exhaled by the cow is adsorbed again, if the secondary methane level is not up to standard, the second closing component (207) and the third closing component (208) are controlled to open and close synchronously, so that the methane gas absorbed in the second time and the products of purifying the excessive methane are released into the breathing filter (200), thereby reducing the greenhouse effect caused by methane emissions.
