Problems solved by technology

Air ducts that have not been cleaned for a long time provide a stable environment for harmful substances. They will continue to breed and spread widely indoors with the air ducts extending in all directions, causing secondary air pollution inside the air conditioner
At present, most central air conditioners generally use coarse-effect filters, which can only filter up to 40% of the inhalable particles in the air, and more than half of the inhalable particles will enter the central air conditioning system

Embodiment Construction

[0028] Because the dirt in the pipeline is different, there are powdery dust, agglomerates, and viscous substances, etc., we use the bucket sampling method. In order to ensure the sampling of the specified area, we rely on the robot walking regulations. method of distance. That is, when sampling is required, put down the shovel, stick it to the pipe wall, and then rely on the robot to move forward to achieve the purpose of taking samples. If we can determine the walking distance L of the robot and measure the effective width R of the shovel, then L* .R=M.M is the sampling area.

[0029] In order to ensure that the sampling process is not subject to other pollution, we have adopted two measures, 1) divide the bucket into two parts, one is connected with the robot, we call it the constant part, and the other part is related to the sampled dirt For the contact parts, we use disposable parts, and replace the disposable bucket every time a sample is taken, so as to prevent impurit...

Abstract

The invention discloses a pipeline dirt quantitative aseptic sampling device and method. And the method multiplies advance distance L of bucket as eliminating dirt from pipe wall by width of bucket R, where L*R=S, so as to get sampling area S on the pipe wall, and then divides dirt weight in the bucket by the sampling area S to get dirt quantity in unit area, thus achieving a quantitative dirt sampling purpose. And its advantages include: 1) quantifying the pipe wall sampling area by integration of electronic control technique and mechanical technique so as to implement quantitative pipe wall sampling; 2)adopting one-off parts to assure sampler asepsis, so as to make the sample not polluted and doped in the sampling course.

Description

technical field [0001] The invention relates to a sampling device and a method thereof, in particular to a pipeline dirt quantitative aseptic sampling device and a method thereof. Background technique [0002] With the development of my country's economy, people's requirements for the quality of life are increasing day by day. As people's life and work rhythm is accelerating day by day, while the requirements for life and work are becoming more and more particular, the voice for improving the living and working environment is also getting higher and higher. . The air pollution caused by the failure of the air conditioning system to be cleaned in time has also attracted more and more people's attention, because it is directly related to the physical and mental health of us and our families. [0003] The proper temperature and humidity in the air conditioning system, especially the air duct system, is an ideal place for the growth and reproduction of bacteria and viruses. Acc...
