Description

Technical Field

[0001] The utility model relates to the technical field of odor pollution source gas sampling, in particular to an odor pollution source sampler with an observation window. Background Art

[0002] Pollution sources refer to the sources of pollutants that cause environmental pollution, usually referring to places, equipment, devices or human bodies that emit harmful substances into the environment or have harmful effects on the environment. Pollution sources are divided into fixed pollution sources and mobile pollution sources. Fixed pollution sources refer to emission places such as flues, chimneys, and exhaust pipes. The exhaust gas they emit contains both solid smoke and dust, as well as a variety of harmful substances in gaseous and aerosol states. Mobile pollution sources mainly refer to exhaust sources such as transportation vehicles, airplanes, and ships. The exhaust gas they emit contains smoke, organic and inorganic gaseous harmful substances.

[0003] At present, the sampling method of odor pollution sources usually adopts a pollution source sampler to sample the odor pollution source gas. The lung principle is applied to suck the polluted gas into the sampling bag through the sampling tube of the sampling smoke gun. That is, a negative pressure is formed in the sampler through a negative pressure pump, and then the odor pollution source gas enters the sampling bag to realize the sampling of the odor pollution source gas.

[0004] Since the current odor pollution source samplers are usually used to sample odor pollution source gases in the field, and the odor pollution source samplers only have the sampling function and do not have the function of storing the sampling bags, when sampling the odor pollution source gases multiple times, other storage devices need to be carried to store the sampled sampling bags, resulting in more equipment being carried when sampling and inconvenient to use. Utility Model Content

[0005] The purpose of the utility model is to provide an odor pollution source sampler with an observation window, which has the characteristics of being convenient for storing multiple sampling bags after sampling when collecting odor pollution source gas, and being convenient for carrying the sampling bags after sampling, and being easy to use.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: a malodor pollution source sampler with an observation window, comprising a base, a sampling cylinder mounted on the upper end surface of the base, a sealing cover mounted on the upper end surface of the sampling cylinder, a sampling tube with a flow valve mounted on the upper end surface of the sealing cover, one end of the sampling tube being connected to a connecting tube penetrating the upper end surface of the sealing cover, the connecting tube being located at one end of the sampling cylinder and being connected to a sampling bag through a threaded seal, and a valve being mounted on the outer side wall of an air inlet pipe of the sampling bag;

[0007] An installation compartment is installed inside the base, and a battery and a negative pressure pump are installed inside the installation compartment in sequence from bottom to top. An exhaust pipe is installed on the outer wall of the negative pressure pump, and the other end of the exhaust pipe passes through the upper end surface of the base and is connected to the sampling cylinder. A card slot is provided on the outer wall of the installation compartment, and a rotating ring is slidably connected to the inside of the card slot. A plurality of evenly distributed support rods are installed on the outer wall of the rotating ring, and a clamping ring is installed on the end of the support rod away from the rotating ring.

[0008] In order to make the sampling cylinder in a negative pressure state, as a preferred odor pollution source sampler with an observation window of the utility model, the bottom of the outer wall of the negative pressure pump is connected to an exhaust pipe, and the other end of the exhaust pipe passes through the outer wall of the installation chamber and extends to the outside of the base.

[0009] In order to make the rotating ring rotate stably, as a preferred odor pollution source sampler with an observation window of the present invention, the cross-sections of the clamping groove and the rotating ring are both "T"-shaped, and the clamping ring is elastic and "C"-shaped.

[0010] In order to facilitate charging of the battery, as a preferred embodiment of the odor pollution source sampler with an observation window of the present invention, a bottom cover is installed at the bottom of the installation compartment, and a charging port is installed on the outer wall of the bottom cover.

[0011] In order to facilitate observation of the condition of the sampling bag, an odor pollution source sampler with an observation window is preferably provided in the present invention, and an observation window is installed through the outer side wall of the sampling tube.

[0012] In order to open the base and store the sampling bags after sampling, a door panel is preferably installed on the front end surface of the base as an odor pollution source sampler with an observation window of the utility model.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] The vacuum pump is then started to draw air from the sampling tube and the air in the sampling bag is discharged from the vacuum pipe, thereby causing the sampling tube to be in a negative pressure state. At this time, the odor pollution source gas can enter the sampling bag through the sampling tube and the connecting tube to sample the odor pollution source gas. After the sampling is completed, the sampling bag containing the odor pollution source gas is taken out of the sampling tube, and then the door panel is opened and the air inlet pipe on the sampling bag is clamped on the clamping ring. When the odor pollution source gas is sampled multiple times, the rotating ring can be rotated, and the rotating ring moves along the clamping groove and drives the multiple support rods to move, so that the multiple support rods drive the multiple clamping rings to move, so that the staff can clamp multiple sampling bags containing the odor pollution source gas on the clamping ring in turn and fix the sampling bags containing the odor pollution source gas. Therefore, when collecting the odor pollution source gas, it is convenient to store the multiple sampled sampling bags and carry the sampled sampling bags, which is convenient to use.
