Description

Technical Field

[0001] This utility model relates to a greenhouse gas monitoring box. Background Technology

[0002] As global climate change becomes increasingly severe, monitoring greenhouse gas emissions (such as carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O)) has become a core task in environmental protection and climate research. Accurate greenhouse gas data is fundamental for formulating emission reduction policies, assessing ecological benefits, and achieving carbon neutrality goals. Traditional monitoring methods mainly rely on fixed stations or satellite remote sensing, but these suffer from low spatial resolution, high costs, and insufficient flexibility.

[0003] Therefore, flexible sampling followed by sample testing is the best monitoring method.

[0004] However, in existing technologies, flexible sampling is time-limited. If you want to sample at a location for different time periods, you need to operate manually, which leads to the limitation of sampling. Each staff member can only operate one sampling device.

[0005] Based on the above problems, we designed a greenhouse gas monitoring box that can take samples at regular intervals. Utility Model Content

[0006] The technical problem to be solved by this invention is to provide a greenhouse gas monitoring box that can take samples at regular intervals.

[0007] To solve the above problems, the present invention adopts the following technical solution: A greenhouse gas monitoring box includes a box body, a battery, a controller, and a power fan. The battery and the power fan are both connected to the controller. The battery is built into the box body. The controller is fixed to the front of the box body. The box body also includes a main duct fixed to the air outlet of the power fan. The end of the main duct is closed. Multiple branch ducts are provided on the outer wall of the main duct. Solenoid valves are installed on the branch ducts and controlled by the controller. An upper box body is detachably installed on the upper part of the box body. The power fan and the main duct are fixedly installed through the upper box body. Connecting components are installed through the branch ducts, and a storage container for storing gas samples is connected through the connecting components.

[0008] Preferably, openings are provided at both the front and rear ends of the box, and side covers are rotatably fitted at the openings. The storage container is inserted through the openings and is adapted to the connecting components.

[0009] Preferably, multiple support legs are provided at the bottom of the box, and the box is lifted more than 1 meter off the ground with the support of the support legs.

[0010] Preferably, a tray is stacked on the upper end of the upper box, and the tray surface is evenly distributed with insertion holes for inserting the storage container.

[0011] Preferably, the connecting assembly includes a connecting cap, the bottom of which is machined with a threaded portion for connecting to the storage container, a connecting tube inserted into the axis of the connecting cap, the upper end of the connecting tube connecting to the solenoid valve, a recessed hole provided at the bottom of the connecting cap, an exhaust hole penetrating the recessed hole provided at the top of the connecting cap, a first through hole provided near the bottom position on the outer wall of the connecting tube, the connecting cap being fixed to the upper housing, and a first solenoid valve installed at the first through hole, the first solenoid valve being connected to the controller.

[0012] Preferably, the storage container includes a container body, with an end cap threadedly connected to the upper end of the container body.

[0022] See Figure 1 and Figure 2 The greenhouse gas monitoring box shown includes a box body 1, a battery, a controller 2, and a power fan 3. The battery and the power fan 3 are both connected to the controller 2. The battery is built into the box body 1. The controller 2 is fixed to the front of the box body 1. The box body also includes a main air duct 4 fixed to the air outlet of the power fan 3. The end of the main air duct 4 is closed. Multiple branch air ducts 41 are provided on the outer wall of the main air duct 4. Solenoid valves 42 are installed on the branch air ducts 41. The solenoid valves 42 are controlled by the controller 2. An upper box body 5 is detachably installed on the upper part of the box body 1. The power fan 3 and the main air duct 4 are fixedly installed through the upper box body 5. A connecting component 6 is installed through the branch air ducts 41. A storage container 7 for storing gas samples is connected through the connecting component 6.

[0023] Based on the above technical solution, if real-time monitoring of gas data is required, a sensor can be selected to detect data such as VOCs and formaldehyde. This sensor can be installed through the connecting component 6.

[0024] The main purpose of this device is to collect greenhouse gases at regular intervals.

[0025] The specific steps are as follows: The start and end times of the collection are set using controller 2.

[0026] When the collection begins, the controller 2 controls the corresponding solenoid valve 42 to open. At this time, the power fan 3 drives the greenhouse gas to flow in and enter the storage container 7 corresponding to the opened solenoid valve 42.

[0027] When the sampling time is reached, the solenoid valve 42 closes.

[0028] See Figure 1 As shown, openings are provided at both the front and rear ends of the box body 1, and side covers 101 are rotatably fitted at the openings. The storage container 7 is inserted through the openings and is adapted to the connecting component 6.

[0029] See Figure 1 As shown, multiple support legs 121 are provided at the bottom of the box 1, and the box 1 is lifted more than 1 meter off the ground with the support of the support legs 121.

[0030] See Figure 3 As shown, a tray 51 is stacked on the upper end of the upper box 5, and the tray 51 has evenly distributed insertion holes 52 for inserting the storage container 7.

[0031] See Figure 4 and Figure 5 As shown, the connecting assembly 6 includes a connecting cap 61. The bottom of the connecting cap 61 is machined with a threaded portion 62 for connecting to the storage container 7. A connecting tube 63 is inserted into the axis of the connecting cap 61. The upper end of the connecting tube 63 is connected to the solenoid valve 42. The bottom of the connecting cap 61 is provided with a recessed hole 64. The top of the connecting cap 61 is provided with an exhaust hole 65 that penetrates the recessed hole 64. A first through hole 66 is provided on the outer wall of the connecting tube 63 near the bottom. The connecting cap 61 is fixed to the upper housing 5. A first solenoid valve 667 is installed at the first through hole 66. The first solenoid valve 667 is connected to the controller 2.

[0032] When the sampling time is reached, solenoid valve 42 opens, and first solenoid valve 667 opens with a delay of 5 to 10 seconds. After solenoid valve 42 opens, power fan 3 drives greenhouse gas into storage container 7. When first solenoid valve 667 opens, excess air is discharged.

[0033] After sampling is completed, first close the first solenoid valve 667, and then close the solenoid valve 42.

[0034] After all samples have been collected, quickly unscrew the storage container 7.

[0035] See Figure 5 and Figure 6As shown, the storage container 7 includes a container body 71. An end cap 72 is threadedly connected to the upper end of the container body 71. The top of the end cap 72 is recessed to form a connecting portion 73. The connecting portion 73 engages with the threaded portion 62. A first recessed hole 74 is provided at the bottom axis of the connecting portion 73. A sliding rod 75 is vertically inserted into the first recessed hole 74. The lower end of the sliding rod 75 passes downward through the first recessed hole 74 and is engaged with a nut 76. A sealing plug 77 is fixed at the upper end of the sliding rod 75. A second through hole 78 for air inlet and outlet is provided near the upper part of the hole wall of 4. A spring 79 is sleeved on the slide rod 75. The spring 79 acts between the sealing plug 77 and the first concave hole 74. When the spring 79 rebounds, the sealing plug 77 seals the second through hole 78. The outer diameter of the connecting tube 63 is smaller than the inner diameter of the first concave hole 74. When the threaded part 62 is screwed down along the connecting part 73 to the limit position, the connecting tube 63 pushes the sealing plug 77 downward, and the second through hole 78 is exposed at this time.

[0036] In the above technical solution, the insertion of the connecting pipe 63 keeps the connecting pipe 63 in a conductive state with the inner cavity of the container body 71. When the solenoid valve 42 is opened, the power fan 3 drives the greenhouse gas into the container body 71. When the first solenoid valve is opened, the excess air is discharged through the concave hole 64 and the first solenoid valve.

[0037] See Figure 1 , Figure 7 and Figure 8 As shown, an exhaust screen 551 is provided on the side of the upper housing 5, and an air inlet hood 552 is installed at the other end of the upper housing 5. The air inlet hood 552 is connected to the air inlet end of the power fan 3, and a filter screen 553 is threadedly connected to the opening of the air inlet hood 552.

[0038] In the above technical solution, the exhaust screen 551 can prevent mosquitoes from entering, and the purpose of the filter screen 553 is to intercept large debris. The size of the filter screen 553 is 30 mesh.
