Description

Technical Field

[0001] This utility model relates to the field of environmental monitoring technology, and more specifically, to an automatic sampling mechanism for environmental monitoring. Background Technology

[0002] Air detection refers to the detection of the composition of air. Gas detectors are important instruments for gas environment monitoring and are instruments and tools for detecting the concentration of gas leaks.

[0003] Among them, the patent with announcement number CN217384897U discloses a gas environment detection device that can quantitatively detect gases, including a sampling cylinder, a sampling mechanism and an adjustment mechanism. A gas detector is installed inside the sampling cylinder, a base is fitted on the outer wall of the sampling cylinder, a pressure control port is opened on the outer wall of the sampling cylinder, and the sampling mechanism is installed on the sampling cylinder.

[0004] When in use, this structure facilitates the sampling of the gas environment through the coordinated use of a sampling cylinder, gas detector, base, electric push rod, piston, positioning block, and delivery hose. It also enables quantitative sampling, ensuring that the amount of air sampled and detected is consistent each time. However, this structure makes it difficult for gas to pass through the device for detection and then be discharged, making it inconvenient to use. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides an automatic sampling mechanism for environmental monitoring, which aims to solve the problems mentioned in the background art.

[0006] This utility model provides the following technical solution: an automatic sampling mechanism for environmental monitoring, including a base, on which a sampling and detection component is disposed;

[0007] The sampling and detection assembly includes an adjustable pad frame on one side of the base, and a support plate on the side of the pad frame away from the base. A gas concentration detection chamber is bolted onto the support plate. A clamping plate is snapped onto one side of the gas concentration detection chamber. A gas detector is embedded in the clamping plate and extends into the gas concentration detection chamber. A controller is embedded at the bottom of the inner cavity of the gas concentration detection chamber. The controller is connected to the gas detector via a wire. An air inlet hood is provided on one side of the surface of the gas concentration detection chamber and is embedded on the outside of the gas concentration detection chamber.

[0008] As can be seen, in the above technical solution, when the airflow enters the gas concentration detection chamber, it is concentrated in the gas concentration detection chamber to avoid the rapid discharge of the airflow causing inaccurate detection by the gas detector. In addition, the gas detector works with the pad frame to adjust the angle of the gas concentration detection chamber during the detection of the airflow to avoid the situation of space restriction. By adjusting the angle of the gas detector and observing the change of the measured value, the angle that makes the reading reach the maximum value can be found to ensure the convenience of detection.

[0009] Optionally, in one possible implementation, the pad frame has two slots, and the bottom of the support plate has two blocks, each of which extends into the slot and engages with it. One end of the pad frame is fixedly provided with a limiting plate, which extends to the outside of the support plate and engages with it. The side of the pad frame away from the limiting plate is fixedly provided with a hinge, the bottom of which extends to the base and is hinged to it. The bottom of the pad frame is engaged with a top frame, which extends to the base and is hinged to it.

[0010] As can be seen, in the above technical solution, the angle of the pad frame and the support plate can be adjusted by the cooperation of the top frame and the hinge, thereby realizing the function of adjusting the angle of the support plate, the gas concentration detection chamber, the card plate and the gas detector, so that the airflow can easily enter the gas concentration detection chamber through the air inlet hood and be detected by the gas detector.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] By setting up sampling and detection components, compared with existing technologies, the overall design is simple and the structure is reasonable. Through the corresponding use of various structures, the functions of adjusting the angles of the support plate, gas concentration detection chamber, card plate and gas detector are made easy for airflow to enter the gas concentration detection chamber through the air inlet hood and be detected by the gas detector.

[0013] Furthermore, when the airflow enters the gas concentration detection chamber, it is concentrated within the chamber, preventing the airflow from being quickly expelled and causing inaccurate detection by the gas detector. In addition, the gas detector works with the pad frame to adjust the angle of the gas concentration detection chamber during the airflow detection process, avoiding situations where space is limited.

[0014] By adjusting the angle of the gas detector and observing the changes in the measured value, the angle at which the reading reaches its maximum value can be found, ensuring convenience during detection. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] As attached Figures 1-4 The automatic sampling mechanism for environmental monitoring shown uses a sampling and detection component on the base 1. When airflow enters the gas-gathering detection chamber 4, it is gathered by the gas-gathering detection chamber 4 to prevent the airflow from being quickly discharged, which would cause inaccurate detection by the gas detector 8. During the detection of airflow, the gas detector 8 works with the pad frame 2 to adjust the angle of the gas-gathering detection chamber 4 to avoid space-constrained scenarios. By adjusting the angle of the gas detector 8 and observing the changes in the measured value, the angle at which the reading reaches the maximum value can be found, ensuring convenience during detection. The specific structural settings of the component are as follows.

[0023] The sampling and detection assembly includes an adjustable pad frame 2 on one side of the base 1, and a support plate 3 on the side of the pad frame 2 away from the base 1. A gas concentration detection chamber 4 is installed on the support plate 3 by bolts. A clamping plate 7 is snapped onto one side of the surface of the gas concentration detection chamber 4. A gas detector 8 is embedded in the clamping plate 7 and extends into the gas concentration detection chamber 4. A controller 5 is embedded in the bottom of the inner cavity of the gas concentration detection chamber 4. The controller 5 is connected to the gas detector 8 by wires. An air inlet hood 6 is provided on one side of the surface of the gas concentration detection chamber 4 and is embedded on the outside of the gas concentration detection chamber 4.

[0024] The pad frame 2 has two slots 9, and the bottom of the support plate 3 has two blocks, each of which extends into the slot 9 and engages with it. One end of the pad frame 2 is fixedly provided with a limiting plate 10, which extends to the outside of the support plate 3 and engages with it. The side of the pad frame 2 away from the limiting plate 10 is fixedly provided with a hinge 11, the bottom of which extends to the base 1 and is hinged to it. The bottom of the pad frame 2 is engaged with a top frame 12, which extends to the base 1 and is hinged to it.

[0025] The specific working principle is as follows: When in use, the base 1 is used as the support point. The angle of the pad frame 2 and the support plate 3 can be adjusted by the cooperation of the top frame 12 and the hinge 11. This enables the adjustment of the angle of the support plate 3, the gas collection detection chamber 4, the clamping plate 7 and the gas detector 8, so that the airflow can easily enter the gas collection detection chamber 4 through the air inlet hood 6 and be detected by the gas detector 8.

[0026] Furthermore, when the airflow enters the gas-gathering detection chamber 4, it is gathered by the gas-gathering detection chamber 4 to prevent the airflow from being discharged quickly and causing the gas detector 8 to be inaccurate. In addition, during the process of detecting the airflow, the gas detector 8 works with the pad frame 2 to adjust the angle of the gas-gathering detection chamber 4 to avoid the occurrence of space-constrained scenarios.

[0027] By adjusting the 8-angle of the gas detector and observing the changes in the measured values ​​(usually the speed reading or signal strength), the angle at which the reading reaches its maximum value can be found, ensuring convenience during detection.

[0028] Unlike existing technologies, this application discloses an automatic sampling mechanism for environmental monitoring. When airflow enters the gas-gathering detection chamber 4, it is gathered by the gas-gathering detection chamber 4 to prevent the airflow from being quickly discharged, which would cause inaccurate detection by the gas detector 8. Furthermore, during the detection of airflow, the gas detector 8 works with the pad frame 2 to adjust the angle of the gas-gathering detection chamber 4 to avoid situations where space is limited. By adjusting the angle of the gas detector 8 and observing the changes in the measured value, the angle at which the reading reaches the maximum value can be found, ensuring convenience during detection.

[0029] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
