Description

Technical Field

[0001] The invention relates to the technical field of environmental detection, and in particular to a sample collection device for environmental detection. Background Art

[0002] my country's urbanization process is accelerating. Many urban constructions are based on improving economic benefits. For economic benefits, when improving urban construction, the environment has gradually been taken seriously. Environmental testing can improve the objective information of environmental conditions. By measuring the corresponding indicators, we can accurately understand the changes in environmental factors such as atmosphere, water quality, soil and noise. Only by understanding the real situation of the environment can we formulate corresponding environmental protection measures in a targeted manner. Through atmospheric testing, we can timely understand the concentration of air pollutants, so as to take control measures in time to prevent pollutants from causing harm to human health; through water quality testing, we can timely understand the degree of water pollution, so as to formulate corresponding governance plans and protect water resources.

[0003] According to application number 202020427014.2, a soil sampling device for soil remediation relates to the field of soil remediation, and includes a fixed plate, a support column is fixedly installed on the upper surface of the fixed plate, and a support plate is fixedly installed on one end of the support column.

[0004] The device uses a telescopic device, a push top block, a buffer notch, a buffer spring, a buffer squeeze plate and a sampling cylinder to reduce the problem of manual collection of soil samples by the staff when sampling the soil, so that the soil samples can be directly collected into the collection box, thereby improving the staff's work efficiency in soil sampling. The use of a buffer spring and a buffer squeeze plate can reduce the hard damage of the soil to the inside of the device when the staff is sampling the soil. The buffering effect of the buffer spring increases the service life of the device, thereby facilitating the soil sampling operation. However, the device samples the soil manually, but the soil is also collected by the staff. This sampling method not only increases the workload of the staff, but also has low sampling efficiency.
