Description

Technical Field

[0001] The utility model relates to the technical field of atmosphere sampling, in particular to a portable multi-height atmosphere sampling device. Background Art

[0002] Atmospheric sampling refers to the method of collecting pollutant samples or polluted air samples in the atmosphere. One type of collection method is to allow a large amount of air to pass through a liquid absorbent or solid adsorbent to enrich the pollutants with lower concentrations in the atmosphere, such as the vacuum method and the filter membrane method. The other type is to use a container (glass bottle, plastic bag, etc.) to collect air containing pollutants; for example, the authorization announcement number "CN220893902U" is a portable multi-height atmospheric sampling device, which includes a box body, a box door at the rear opening of the box body, and a side of the box door is connected to the box body by a hinge. The other side of the door is connected to the box body through a lock; a vertical shoulder strap is fixed to the outer surface of the box body on the other side of the door; a horizontal partition is provided on the lower side of the box body, which divides the box body into a first cavity and a second cavity. A number of winding assemblies are arranged vertically on the back side of the first cavity. A fixing card is provided on the side wall of the first cavity on one side of the winding assembly, and a sampling bottle is detachably provided on the fixing card. An air pump is fixed to the bottom surface of the second cavity. A battery is fixed to the bottom surface of the second cavity on the side of the air pump. The air pump is electrically connected to the battery through a line. It is simple to operate and easy to use, and is suitable for a variety of places.

[0003] When the current atmospheric sampling device is in use, the first one-way valve only allows air to enter, and the second one-way valve only allows air to exit. The air outlet connector is connected to the sampling tube. When the air pump is working, the first and second one-way valves open simultaneously, allowing air to be sucked into the sampling bottle. When the air pump stops working, the two one-way valves close, and the atmospheric sample remains inside the sampling bottle.

[0004] During use, a traditional atmospheric sampling device fixes the sampling bottle inside the box and uses an air pump and a one-way valve to allow the atmosphere to remain inside the sampling bottle. Since the fixed spacing between multiple sampling bottles is small, the contents of the gas samples inside the multiple sampling bottles are similar, resulting in a low reference value for the detection data of the atmospheric samples inside the sampling bottles by the detection device. Utility Model Content

[0005] In response to the shortcomings of the existing technology, the utility model provides a portable multi-height atmospheric sampling device, which solves the problem that during use of traditional atmospheric sampling devices, the sampling bottle is fixed inside the box, and the atmosphere is allowed to remain inside the sampling bottle through an air pump and a one-way valve. Since the fixed spacing between multiple sampling bottles is small, the contents of the gas samples inside the multiple sampling bottles are similar, resulting in a low reference value of the detection data of the atmospheric samples inside the sampling bottles by the detection device.

[0009] Preferably, the fixing device includes: a plurality of circular rings, which are respectively installed on the outer walls of the plurality of round rods; a plurality of splints, which are respectively movably connected to the inner walls of the plurality of circular rings; a plurality of bolts, which are respectively rotatably connected to the inner walls of the plurality of circular rings through bearings, and are threadedly connected to the inner walls of the plurality of splints; wherein the rotation of the bolts drives the splints to move.

[0011] Beneficial effects

[0012] The utility model provides a portable multi-height atmospheric sampling device. It has the following beneficial effects: the portable multi-height atmospheric sampling device uses mounting nails in conjunction with a chassis to fix round rods. Multiple round rods are connected together by the mounting device. The multiple round rods are spaced relatively far apart. After multiple collecting devices are fixed to the outer walls of the multiple round rods, the multiple collecting devices are spaced relatively far apart. This results in significant differences in the contents of gas samples inside multiple sampling bottles, thereby improving the reference value of the detection device for detecting atmospheric samples inside the sampling bottles.

The detailed connection means are well-known technologies in this field. The following mainly introduces the working principle and process.

[0021] In traditional atmospheric sampling devices, a sampling bottle is fixed inside a box. An air pump and a one-way valve are used to keep the atmosphere inside the sampling bottle. Due to the small spacing between the multiple sampling bottles, the gas samples inside the bottles have similar contents, resulting in a low reference value for the atmospheric sample data inside the sampling bottles.

[0022] In view of this, the utility model provides a portable multi-height atmospheric sampling device, which uses mounting nails to cooperate with a chassis to fix the round rods, and connects multiple round rods together through the mounting device. The distance between the multiple round rods is relatively far. After the multiple collecting devices are fixed on the outer walls of the multiple round rods, the distance between the multiple collecting devices is relatively large, so that the contents of the gas samples inside the multiple sampling bottles vary greatly, thereby improving the reference value of the detection device for the detection data of the atmospheric samples inside the sampling bottles.
