Description

Technical Field

[0001] The present application relates to the field of environmental monitoring, and in particular to an environmental monitoring instrument. Background Art

[0002] Environmental monitoring instruments are mainly used to monitor various parameters of indoor and outdoor environments. Environmental monitoring instruments are also commonly used in the meteorological field as auxiliary tools for meteorological monitoring and disaster prevention. Environmental monitoring instruments can be used to monitor air quality, ambient temperature and humidity, and special gas concentrations, and can also alarm based on temperature and toxic and harmful gas concentrations.

[0003] The outdoor environmental monitoring instrument used in the meteorological field assists the meteorological information collection device to collect air quality information. The environmental monitoring instrument is usually directly integrated into the meteorological information collection device. A mesh air inlet is set on the shell of the environmental monitoring instrument, and a gas monitoring body is set at the air inlet to monitor the air composition. However, when the wind speed is fast, it will seriously affect the monitoring results. Summary of the invention

[0004] The present application provides an environmental monitor, which is used to reduce the wind speed at the air inlet of the environmental monitor and ensure the monitoring results of the environmental monitor.

[0005] The present application provides an environmental monitoring instrument, including a shell, a monitoring body and a mitigation tube; the shell has a accommodating cavity, and an air inlet is arranged on one side wall of the shell; the monitoring body is arranged in the accommodating cavity, and the monitoring body has a gas monitoring channel; the mitigation tube is arranged in the accommodating cavity and is located between the air inlet and the gas monitoring channel, and the two ends of the mitigation tube are respectively connected to the air inlet and the gas monitoring channel, and the mitigation tube includes a plurality of sub-tubes, and the plurality of sub-tubes are connected in sequence, and an angle is set between two adjacent sub-tubes.

[0006] A deceleration tube is arranged between the monitoring body and the air inlet in the present application. High-speed wind from the outside enters the deceleration tube through the air inlet. When the air flows between the sub-tubes in the deceleration tube, the airflow will hit the inner wall of the next sub-tube due to the angle between adjacent sub-tubes, thereby reducing the wind speed and making the airflow smoother. In turn, the airflow speed entering the gas monitoring channel in the monitoring body is low, which helps the environmental monitor to work stably.

[0007] In some embodiments of the present application, the mitigation tube is fixedly connected to the inner wall of the housing, and the mitigation tube is fixedly connected to the monitoring body. The stable connection between the mitigation tube, the monitoring body and the housing can prevent the mitigation tube from breaking when the airflow impacts the mitigation tube.

[0008] In some embodiments of the present application, the sub-tube is provided in two sections, and the angle between the axes of the two sections of the sub-tube is 0° to 90°. The two sections of the sub-tube can make the second section of the sub-tube play a corresponding role in slowing down the airflow, and the angle of 0° to 90° can play a certain effect of reducing the airflow velocity.

[0009] In some embodiments of the present application, the mitigation pipe further includes an elbow joint, and two adjacent sections of sub-pipes are connected and communicated through the elbow joint. The elbow joint can facilitate installation and increase connection strength between the two adjacent sections of sub-pipes.

[0010] In some embodiments of the present application, the diameter of the mitigation tube gradually increases in the direction from the air inlet to the gas monitoring channel and in the axial direction of the mitigation tube. As the airflow flows toward the gas monitoring channel, the cross-sectional area in the airflow direction gradually increases, which helps to reduce the airflow velocity.

[0011] In some embodiments of the present application, the opening of one end of the mitigation tube near the air inlet is tilted downward. The mitigation tube near the air inlet is tilted downward to prevent rainwater from flowing into the gas monitoring channel, and plays a certain waterproof protection role for the monitoring body.

[0012] In some embodiments of the present application, an air outlet is also provided on the housing, and the air outlet and the air inlet are located on the two side walls of the housing, the mitigation tube covers part of the air inlet, and the other area of ​​the air inlet is connected to the air outlet through the accommodating cavity. The air inlet, the accommodating cavity, and the air outlet that are not covered by the mitigation tube form a complete gas channel, which can cool down the monitoring body in hot weather to prevent high temperature from damaging the components in the monitoring body or reducing the service life of the environmental monitor.

[0013] In some embodiments of the present application, the air outlet is arranged on the bottom wall of the housing, and is arranged on the side of the bottom wall away from the air inlet. The air outlet is arranged on the bottom wall of the housing, which is beneficial to the position design of the environmental monitor itself. The air outlet is arranged on the side away from the air inlet to increase the volume of the heat dissipation duct, increase the heat dissipation area in the environmental monitor, and improve the heat dissipation effect.

[0014] In some embodiments of the present application, a mesh baffle is provided at the air inlet of the housing, which can prevent fallen leaves and other objects from floating into the clogging mitigation tube. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Environmental monitoring instruments are mainly used to monitor various parameters of indoor and outdoor environments. Environmental monitoring instruments are also commonly used in the meteorological field as auxiliary tools for meteorological monitoring and disaster prevention. Environmental monitoring instruments can be used to monitor air quality, ambient temperature and humidity, and special gas concentrations, and can also alarm based on temperature and toxic and harmful gas concentrations.

[0026] The outdoor environmental monitoring instrument used in the meteorological field assists the meteorological information collection device to collect air quality information. The environmental monitoring instrument is usually directly integrated into the meteorological information collection device. A mesh air inlet is set on the shell of the environmental monitoring instrument, and a gas monitoring body is set at the air inlet to monitor the air composition. However, when the wind speed is fast, it will seriously affect the monitoring results.

[0027] To do this, please refer to Figure 1 The present application provides an environmental monitoring instrument, including a housing 1, a monitoring body 2 and a mitigation tube 3.

[0028] Please refer to Figure 1 The housing 1 has a receiving cavity 11, and an air inlet 12 is arranged on one side wall of the housing 1. The housing 1 is a conventional housing 1 of an environmental monitor, and the material may be plastic. In order to improve durability, alloy material may also be used; the housing 1 may be square as a whole, or may be in other shapes. The air inlet 12 may be circular, square or in other irregular shapes.

[0029] Please refer to Figure 1 The monitoring body 2 is disposed in the accommodating cavity 11, and the monitoring body 2 has a gas monitoring channel 21. The monitoring body 2 may be an internal monitoring component of a conventional environmental monitor, may include the gas monitoring part required by the present application, and has the above-mentioned gas monitoring channel 21, and may also include other monitoring functional structures, such as temperature and humidity monitoring, special gas concentration monitoring, etc.

[0030] Please refer to Figure 2 The mitigation tube 3 is arranged in the accommodating cavity 11 and is located between the air inlet 12 and the gas monitoring channel. The two ends of the mitigation tube 3 are respectively connected to the air inlet 12 and the gas monitoring channel 21. The mitigation tube 3 includes multiple sections of sub-tubes 31, and the multiple sections of sub-tubes 31 are connected in sequence, and an angle is set between two adjacent sections of sub-tubes 31.

[0031] A deceleration tube 3 is arranged between the monitoring body 2 and the air inlet 12 in the present application. The external high-speed wind enters the deceleration tube 3 through the air inlet 12. When the air flows between the sub-tubes 31 in the deceleration tube 3, the airflow will hit the inner wall of the next sub-tube 31 due to the angle between adjacent sub-tubes 31, thereby reducing the wind speed and making the airflow smoother, thereby reducing the airflow speed entering the gas monitoring channel 21 in the monitoring body 2, which helps the environmental monitor to work stably.

[0032] Please refer to Figure 2 In some examples, the deceleration tube 3 may be a plastic tube or a metal tube.

[0033] In some examples, the sub-tube 31 may be a straight tube or a spiral tube. When the sub-tube 31 is a spiral tube, all the sub-tubes 31 may be identified as one spiral tube.

[0034] Please refer to Figure 2 In some examples, different sub-tubes 31 may have different lengths or may be the same.

[0035] Please refer to Figure 2 In some examples, the mitigation tube 3 is fixedly connected to the inner wall of the housing 1, and the mitigation tube 3 is fixedly connected to the monitoring body 2. The stable connection between the mitigation tube 3 and the monitoring body 2 and the housing 1 can prevent the mitigation tube 3 from being broken when the airflow impacts the mitigation tube 3.

[0036] In some examples, the fixed connection may be flange connection, welding, or fixing the pipe by a pipe bracket. The fixed connection only requires that the mitigation pipe 3 and the housing 1 are relatively fixed.

[0037] Please refer to Figure 2 In some examples, the mitigation pipe 3 includes multiple sections of sub-pipes 31 , and thus can be installed in a manner where one section of the sub-pipes 31 is connected to the housing 1 , and another section of the sub-pipes 31 is connected to the monitoring body 2 .

[0038] In some examples, the sub-tube 31 is provided in two sections, and the angle between the axes of the two sections of the sub-tube 31 is 0° to 90°. The two sections of the sub-tube 31 can make the second section of the sub-tube 31 play a corresponding role in slowing down the airflow, and the angle of 0° to 90° can play a certain effect of reducing the airflow velocity.

[0039] Please refer to Figure 2 In some examples, the angle between the two sections of sub-tubes 31 is preferably 90° and 0°.

[0040] Please refer to Figure 2 For example, when the opening direction of the air inlet 12 is in the same direction as the inlet direction of the gas monitoring channel 21, the number of sub-tubes 31 can be three sections, and the two adjacent sections of sub-tubes 31 are connected at 90 degrees. At this time, the air inlet and air outlet directions of the deceleration tube 3 can be made parallel.

[0041] Alternatively, when the opening direction of the air inlet 12 is perpendicular to the inlet direction of the gas monitoring channel 21, the number of sub-tubes 31 can be two sections, and the two sections of sub-tubes 31 are connected at 90°. At this time, the air inlet and air outlet directions of the deceleration tube 3 can be made parallel; the number of sub-tubes 31 can also be three sections, two sections of sub-tubes 31 are connected at 90°, and the other two sections of sub-tubes 31 are connected at 0° to form a rotating structure, which can also achieve the above-mentioned effect.

[0042] Please refer to Figure 2 In some examples, the number of sub-tubes 31 can be two, three or five, all of which can meet usage requirements.

[0043] Please refer to Figure 2 In some examples, the mitigation pipe 3 further includes an elbow joint 32, and the two adjacent sections of sub-pipes 31 are connected and communicated through the elbow joint 32. The elbow joint 32 can facilitate the installation and high connection strength between the two adjacent sections of sub-pipes 31.

[0044] In some examples, the angle of the elbow joint 32 can be 0° to 90°. When the angle of the elbow joint 32 is 0°, the elbow structure is a U-shaped joint.

[0045] In some examples, the material of the elbow joint 32 can be the same as that of the reduction pipe 3 , and both can be polyethylene plastic.

[0046] Please refer to Figure 2 In some examples, the diameter of the mitigation tube 3 gradually increases in the direction from the air inlet 12 to the gas monitoring channel 21 and in the axial direction of the mitigation tube 3. As the airflow flows toward the gas monitoring channel 21, the cross-sectional area in the airflow direction gradually increases, which helps to reduce the airflow velocity.

[0047] In some examples, the cross-sectional area may gradually increase in a linear manner, that is, the tube may be a conical tube or a truncated cone tube, and the surface of the tube may be a non-cylindrical surface. Alternatively, two tubes of different diameters may be used, each of which is a cylindrical tube, which may also meet the need for a gradually increasing cross-sectional area.

[0048] Please refer to Figure 3 In some examples, the opening of the mitigation tube 3 at one end close to the air inlet 12 is tilted downward. The mitigation tube 3 close to the air inlet 12 is tilted downward to prevent rainwater from flowing into the gas monitoring channel 21, and plays a certain waterproof protection role for the monitoring body 2.

[0049] In some examples, the inclined portion may be a portion of the sub-tube 31 of the deceleration tube 3 , or may be a section of the sub-tube 31 .

[0050] In some examples, the tilt angle may be 10°, 15°, or 30°.

[0051] Please refer to Figure 3In some examples, the housing 1 is further provided with an air outlet 13, which is located on the two side walls of the housing 1 together with the air inlet 12. The mitigation tube 3 covers part of the air inlet 12, and the other part of the air inlet 12 is connected to the air outlet 13 through the accommodating cavity 11. The air inlet 12, the accommodating cavity 11, and the air outlet 13 that are not covered by the mitigation tube 3 form a complete gas channel, which can cool down the monitoring body 2 in hot weather to prevent high temperature from damaging the components in the monitoring body 2 or reducing the service life of the environmental monitor.

[0052] In some examples, the air outlet 13 may be a circular hole, a square hole, or a special-shaped hole.

[0053] In some examples, the air outlet 13 may be provided as one or more air outlets.

[0054] Please refer to Figure 3 In some examples, the air outlet 13 is disposed on the bottom wall of the housing 1, and is disposed on a side of the bottom wall away from the air inlet 12. The air outlet 13 disposed on the bottom wall of the housing 1 is beneficial to the position design of the environmental monitor itself, and being disposed on a side away from the air inlet 12 can increase the volume of the heat dissipation duct, increase the heat dissipation area in the environmental monitor, and improve the heat dissipation effect.

[0055] In some examples, the side walls and bottom walls described in the text are the installation directions of the environmental monitor when in use, which may not be consistent with the directions shown in the figure ( Figure 3 The main viewing direction is shown when in use).

[0056] In some examples, the air outlet 13 may be disposed only on the bottom wall of the housing 1 , or may be disposed simultaneously on the bottom wall of the housing 1 and on a side wall opposite to the air inlet 12 .

[0057] Please refer to Figure 3 In some examples, the housing 1 is provided with a mesh baffle 14 at the air inlet 12. The mesh baffle 14 can prevent fallen leaves and other objects from floating into the mitigation tube 3 and blocking it.

[0058] In some examples, the mesh baffle 14 can be integrally formed with the housing 1, or can be independently formed and then installed by bolts.

[0059] In the description of this specification, specific features, structures, materials or characteristics may be combined in an appropriate manner in any one or more embodiments or examples.

[0060] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
