Building construction environment monitoring sample collection device

Abstract

The invention relates to the field of building construction environment monitoring, in particular to a building construction environment monitoring sample collection device which comprises a bottom plate, a through hole is formed in the middle of the bottom plate, fine adjustment mechanisms are installed at the four corners of the lower end of the bottom plate, and supporting plates are fixedly connected to the middles of the two sides, the front side and the rear side of the upper end of the bottom plate. The upper ends of the four supporting plates are jointly and fixedly connected with a top plate. A mud scraping mechanism is arranged on the outer side of a barrel and connected with a driving motor through a first transmission mechanism and a second transmission mechanism, and the driving motor drives the mud scraping mechanism to operate through the first transmission mechanism and the second transmission mechanism while lifting the barrel through the lifting mechanism, so that a limiting ring of the mud scraping mechanism slides on the barrel; and the sliding direction is opposite to the moving direction of the barrel, so that wet soil on the surface of the barrel can be scraped off in the process of pulling the barrel out of the ground, and the wet soil is prevented from being adhered to hands or clothes of a worker when the worker collects a sample.

Description

technical field [0001] The invention relates to the field of building construction environment monitoring, in particular to a sample collection device for building construction environment monitoring. Background technique [0002] During building construction, the staff need to collect samples of the construction site, analyze the environment of the construction site, and facilitate the staff to monitor the construction environment, and the collection device is one of the devices used in the monitoring of the construction environment. [0003] At present, when the sample collection device used in building construction environment monitoring is in use, if the ground is uneven, in order to ensure that the collection device is placed vertically on the ground, it is necessary to use tools to level the ground, which is troublesome. Because it is manually leveled, it is difficult. Ensure that the ground remains flat after shoveling, and during the sample collection process, when t...

[0003] At present, when the sample collection device used in building construction environment monitoring is in use, if the ground is uneven, in order to ensure that the collection device is placed vertically on the ground, it is necessary to use tools to level the ground, which is troublesome. Because it is manually leveled, it is difficult. Ensure that the ground remains flat after shoveling, and during the sample collection process, when the sample collection structure is inserted into the soil, since the sample collection structure of the device has no limit structure, the sample collection structure is prone to tilt when it contacts the ground , so that the collected samples are not standard. If the soil surface is relatively wet, when the sample collection structure is pulled out from the soil, some wet soil will remain on the surface of the sample collection structure. When the staff collects the samples, the wet soil will stick to the on the hands or clothing of workers, causing contamination
