Description

Technical Field

[0001] The utility model specifically relates to the technical field of forestry carbon sinks, and in particular to an online monitoring device. Background Art

[0002] Forestry carbon sink refers to the generation of additional economic value through market-based participation in forestry resource transactions, including forest management carbon sink and afforestation carbon sink. In terms of carbon sink monitoring, it mainly includes the following aspects: atmospheric CO2 monitoring: monitoring the concentration and changing trend of CO2 in the atmosphere through the use of meteorological observation stations, remote sensing technology and drones; forest monitoring: monitoring the carbon storage, growth status and degree of damage of forest ecosystems through remote sensing technology, ground observation and sampling; soil monitoring: monitoring the organic matter content and CO2 emissions in the soil by collecting soil samples and conducting laboratory analysis to assess the contribution of soil to carbon sinks; ocean monitoring: monitoring the absorption and storage of CO2 in the ocean by measuring indicators such as dissolved CO2 concentration, surface temperature and pH value in seawater.

[0003] In the process of forestry carbon sink indicator monitoring, one of the items is atmospheric CO2 monitoring, which requires the use of online monitoring equipment. In the existing technology, online monitoring equipment generally uses an air pump to draw air into the detection chamber, and then uses a CO2 sensor for monitoring.

[0004] However, since the above-mentioned online monitoring equipment uses an air pump to draw air into the detection chamber, it is easy to cause the air concentration in the detection chamber to increase. The increase in air concentration affects the accuracy of the monitoring results, so there is room for improvement. Utility Model Content

[0005] The utility model aims to solve the shortcomings in the prior art and proposes an online monitoring device.

[0008] Furthermore, dust filters are provided at both ends of the housing. The cross-section of the dust filter is in a U-shaped structure, and the dust filter covers both ends of the flow-through cavity. The setting of the dust filter can filter the dust in the incoming air and reduce the interference of the dust on the detection result.

[0009] Furthermore, a limiting post is provided at one end of the dust filter close to the housing, and a limiting groove is formed in the outer wall of the housing close to the dust filter. The limiting post is adapted to the limiting groove, and the limiting post is fixed in the limiting groove through a limiting mechanism. When installing the dust filter, the limiting post can be directly inserted into the limiting groove, and then fixed by the limiting mechanism, which improves the firmness of the installation of the dust filter.

[0010] Furthermore, the limiting mechanism includes a sliding hole formed in the inner wall of the top of the limiting post. A plug rod is slidably connected to the inner wall of the sliding hole. A return spring is sleeved on the outer wall of the plug rod. A slot is formed in the outer wall of the limiting post close to the plug rod. The plug rod is adapted to the slot. After the limiting post is inserted into the limiting groove, the plug rod can be embedded into the slot under the action of the return spring, thereby limiting the limiting post and improving the convenience of operation.

[0011] Furthermore, a pull tab is provided at one end of the plug rod away from the slot. The pull tab is in a semi-circular ring structure. The setting of the pull tab can facilitate pinching the pull tab by hand to pull the plug rod to move, which improves the convenience of operation.

[0012] Furthermore, one end of the plug rod close to the slot is in a frustum shape. The design of one end in a frustum shape can make the end of the plug rod narrower, which improves the convenience of the plug rod being embedded into the slot.

[0013] Furthermore, flow equalizing plates are provided on both sides of the inner wall of the flow-through cavity. A plurality of diversion holes are formed in the surface of the flow equalizing plate, and the diversion holes are inclined. The setting of the flow equalizing plates can facilitate the uniform delivery of air to the infrared emitter, avoid the occurrence of air accumulation, and improve the accuracy of the monitoring result.

[0014] The beneficial effects of the present utility model are as follows:

[0015] 1. When in use, install the device on the trunk of a forest tree, control the motor to start, and the motor can drive the fan blades to rotate. The rotation of the fan blades drives the air circulation in the circulation cavity. When the air enters the circulation cavity, the infrared transmitter can emit infrared rays. The emitted infrared rays can be received by the infrared receiver after being transmitted through the air. Based on the principle of infrared absorption, carbon dioxide absorbs specific wavelengths of infrared rays. The processor can determine the concentration by measuring the degree of absorption. After the concentration is determined, it will be displayed on the display screen. At the same time, the wireless signal transmitter sends the signal out, and the staff can see the real-time data in the control room, which can achieve good monitoring effects and improve the accuracy of forestry carbon sink monitoring.

[0016] 2. The dust filter can filter the dust in the incoming air to reduce the interference of dust on the detection results; when installing the dust filter, the limit column can be directly inserted into the limit slot, and then fixed with the limit mechanism, which improves the firmness of the dust filter installation; when the limit column is inserted into the limit slot, the plug rod can be embedded in the slot under the action of the reset spring, and then the limit column can be limited, which improves the convenience of operation; the flow equalizing plate can easily and evenly deliver air to the infrared transmitter, avoid air accumulation, and improve the accuracy of the monitoring results.
