[0036] At present, the sampling manifolds of environmental air monitoring stations at all levels are designed and manufactured in accordance with the standard of HJ / T193 - 2005 "Technical Specifications for Ambient Air Quality Automatic Monitoring". There is no clear description for the exhaust of monitoring instruments. The problem of the sampling pipe and the exhaust of monitoring instruments was not considered at the initial stage of the construction of the environmental monitoring station.

[0037] During the design process, the inventor found that when installing the instruments in the environmental monitoring station, the exhaust of the monitoring instruments is either randomly discharged into the monitoring station room, polluting the indoor air; or directly opening a hole in the wall of the monitoring station to discharge it outdoors. The exhaust of the sampling manifold also needs to open a hole in the wall to discharge it outdoors. Multiple holes lead to a large amount of construction work, and waterproof treatment needs to be done at each hole. If the treatment is not good, it will affect the rainproof and anti - corrosion properties of the station building.

[0038] In view of this, as Figure 1 - Figure 2 shown, in a first aspect, an embodiment of the present application provides an exhaust device, including: a converging structure 10, including a converging hood 101, an intake pipe 102, and an intake joint 103. The converging hood 101 is configured with a converging cavity. The intake pipe 102 is connected to the converging hood 101 through the intake joint 103, and both the intake pipe 102 and the intake joint 103 are in communication with the converging cavity; an exhaust fan 20, which is connected to the converging hood 101 and in communication with the converging cavity to discharge the gas discharged from the intake pipe 102 and the intake joint 103 into the converging cavity.

[0039] Exemplarily, the confluence cover 101 includes a confluence portion and a mounting portion, wherein the confluence portion is connected to the mounting portion, and the confluence portion and the mounting portion may be integrally stamped, or may be formed as a whole by welding or injection molding, wherein the mounting portion is located at the outer edge of the confluence portion, and may be used to fix the confluence cover 101 and the exhaust fan 20, the confluence portion includes but is not limited to a cylindrical shape, and the mounting portion includes but is not limited to a square shape, the confluence portion may be located on the side of the mounting portion away from the exhaust fan 20, and the confluence portion is provided with the intake pipe 102 and the intake connector 103.

[0040] It should be noted that the air intake pipe 102 and the air intake connector 103 can be used to connect different components, and the air intake volume of the air intake pipe 102 and the air intake connector 103 can be set according to actual conditions. At the same time, there is no specific limitation on the position of the air intake pipe 102 and the air intake connector 103 in the confluence portion. As long as the gas can be discharged into the confluence cavity, they will not be elaborated here.

[0041] In the above-mentioned implementation process, the collector 101 is respectively provided with an air intake pipe 102 and an air intake connector 103 which are connected to its collector cavity, so that the air intake pipe 102 and the air intake connector 103 are integrated in the collector 101, and the gas entering the collector cavity from the air intake pipe 102 and the air intake connector 103 can be discharged through the exhaust fan 20. The entire discharge process can not only make the interior of the monitoring station more tidy and free of air pollution, but also reduce the number of openings in the monitoring station, thereby reducing the workload during installation and construction, improving work efficiency, and reducing the risk of water leakage and corrosion, so that the monitoring station can be put into operation in a shorter time.

[0042] like Figure 1 As shown, the air intake connectors 103 are configured in plurality, and the plurality of air intake connectors 103 are spaced apart along the periphery of the collector 101. For example, six air intake connectors 103 are configured, and the six air intake connectors 103 are equally spaced apart on the periphery of the collector 101. Of course, it is not excluded that the spacings of the six air intake connectors 103 are set to be different.

[0043] In the above implementation process, several air inlet connectors 103 are integrated into the manifold 101 to realize the concentration of air paths and facilitate layout, which can make the interior of the monitoring station neater and free of air pollution. The number of openings in the monitoring station is reduced, which makes the construction simple and reduces the need for waterproofing construction, greatly improving work efficiency and enabling the monitoring station to be put into operation in a shorter time.

[0044] In some embodiments, the intake pipe 102 and the intake joint 103 are located on the same side of the confluence cover 101. For example, both the intake pipe 102 and the intake joint 103 are located on the side of the confluence cover 101 that faces away from the exhaust fan 20.

[0045] In the above implementation process, the intake pipe 102 and the intake joint 103 are integrated on the same side of the confluence cover 101, which is convenient for layout, making the interior of the monitoring station cleaner, free of air pollution, and the structure more compact, greatly improving work efficiency.

[0046] In some embodiments, the intake direction of the intake pipe 102 is the same as the intake direction of the intake joint 103. For example, the intake direction of both is the direction from the confluence cover 101 to the exhaust fan 20.

[0047] In the above implementation process, under the action of the intake pipe 102 and the intake joint 103, gas can enter the confluence cavity of the confluence cover 101 along the same direction, avoiding the random flow of gas in the confluence cavity, thereby reducing noise and improving the user experience.

[0048] In some embodiments, the exhaust fan 20 is arranged on the side of the confluence cover 101 that faces away from the intake pipe 102, and the exhaust direction of the exhaust fan 20 is the same as the intake direction of the intake pipe 102.

[0049] In the above implementation process, the gas entering the confluence cavity can be directly discharged by the exhaust fan 20, improving the discharge efficiency and avoiding the risk of gas random flow in the confluence cavity due to untimely gas discharge. At the same time, arranging the exhaust fan 20 on the side of the confluence cover 101 that faces away from the intake pipe 102 facilitates the fixation of the exhaust fan 20 to the confluence cover 101.

[0050] In some embodiments, the exhaust device further includes a mounting plate 30, which is arranged on the side of the exhaust fan 20 that faces away from the confluence cover 101, and the mounting plate 30 is provided with exhaust holes that communicate with the exhaust fan 20.

[0051] In the above implementation process, both the confluence cover 101 and the exhaust fan 20 can be fixed through the mounting plate 30, making the structure more compact, facilitating gas discharge, improving the discharge efficiency, and avoiding air pollution in the monitoring station.

[0052] Please refer to again Figure 1The exhaust device also includes a fixing member 40, which includes but is not limited to a screw, and the number of the fixing member 40 can be configured as four. One end of the fixing member 40 is sequentially passed through the collector 101, the exhaust fan 20 and the mounting plate 30 to fix the collector 101, the exhaust fan 20 and the mounting plate 30.

[0053] In the above implementation process, the collector 101, the exhaust fan 20 and the mounting plate 30 can form a whole under the action of the fixing member 40, which is beneficial to the fixation of the collector 101, the exhaust fan 20 and the mounting plate 30, making the structure more compact and the discharge efficiency higher.

[0054] like Figure 2 As shown, in a second aspect, the present application also provides an environmental monitoring station, including: a sampling component, which is equipped with an exhaust port, and the sampling component includes but is not limited to a sampling main pipe; a monitoring instrument, which is equipped with an exhaust pipe; and an exhaust device as described above, wherein the air inlet pipe 102 of the exhaust device is connected to the exhaust port (for example, the two are connected by a hose), and the air inlet connector 103 of the exhaust device is connected to the exhaust pipe.

[0055] In the above-mentioned implementation process, by integrating the air inlet pipe 102 connected to the exhaust port of the sampling piece and the air inlet connector 103 connected to the exhaust pipe of the monitoring instrument into the condenser cover 101 of the exhaust device, it is convenient to organize and arrange the interior of the monitoring station more tidy and free of air pollution. The number of openings in the monitoring station is reduced, the construction is simple, and the waterproofing construction is less, which greatly improves the work efficiency and allows the monitoring station to be put into operation in a shorter time.

[0056] In some embodiments, the environmental monitoring station further comprises a fixed wall 60, one side of the fixed wall 60 is connected to the exhaust device, and the fixed wall 60 is provided with a discharge hole connected to the exhaust device.

[0057] In the above implementation process, the exhaust device is fixed to the fixed wall 60, which is conducive to the concentration of the gas path and is easy to organize and arrange, making the interior of the monitoring station neater, simpler in construction, and greatly improving work efficiency.

[0058] In some embodiments, the environmental monitoring station further includes a louver 70 , wherein the louver 70 is disposed at the discharge hole, and / or the louver 70 is disposed at a side of the fixed wall 60 away from the exhaust device, and the louver 70 corresponds to the discharge hole.

[0059] During the above implementation process, the gas exhausted by the exhaust fan 20 passes through the exhaust hole and is discharged to the outside of the monitoring station, which can avoid air pollution of the monitoring station. At the same time, under the action of the louver 70, the exhaust hole can be protected from insects and rain, which is beneficial for related instruments to monitor the environment.

[0060] In all embodiments of the present application, "big" and "small" are relative, "many" and "few" are relative, and "up" and "down" are relative. For the expression of such relative terms, the embodiments of the present application will not elaborate further.
