Portable outdoor water sample taking and detecting device

Abstract

The invention discloses a portable outdoor water sample taking and detecting device which comprises a motor, a pulley, a steel wire rope, a sampling bucket, a detection probe and a water level sensor.The device is simple in structure, the central shaft of the pulley is connected with the motor, the steel wire rope is positioned in the groove of the pulley, one end of the steel wire rope is connected with the sampling bucket; the detection probe is positioned in the sampling bucket, the pulley is driven to rotate by the motor, the steel wire rope rotates along with the pulley, the sampling bucket can be automatically released into a well, the sampling bucket can be submersed into water to take water samples because of the weight of the sampling bucket self, moreover, a part of indexes canbe detected once the detection probe is in contact with the water samples, the indexes can be transmitted to a mobile terminal or a remote server, and the water level in the sampling bucket can be monitored by using the water level sensor, so that the detection data truth and the reliability can be improved; through reverse rotation of the motor, the sampling bucket with the water samples can be automatically lifted outside the well through the steel wire rope, so that the working intensity can be greatly alleviated.

Description

technical field [0001] The invention relates to the technical field of water sample collection and detection, in particular to a portable field water sample collection and detection device. Background technique [0002] The collection of field water samples is mainly divided into the collection of surface water and groundwater samples, and most of the groundwater samples come from well water. In actual sampling, the water wells are generally deep and cannot be directly inserted into the water body for sampling. Secondly, due to the high buoyancy of the well water, the commonly used plastic collection bottles (barrels) cannot be immersed in water, or can only rely on plastic collection bottles ( bucket) to collect a little water sample, but the existing large and expensive collector requires a lot of manpower, and it is extremely inconvenient to carry and operate, so it is not suitable for the collection of groundwater in the field. Moreover, the collected water samples can ...

In actual sampling, the water wells are generally deep and cannot be directly inserted into the water body for sampling. Secondly, due to the high buoyancy of the well water, the commonly used plastic collection bottles (barrels) cannot be immersed in water, or can only rely on plastic collection bottles ( bucket) to collect a little water sample, while the existing large and expensive collector requires a lot of manpower, it is extremely inconvenient to carry and operate, and is not suitable for field groundwater collection

Moreover, the collected water samples can only be detected after collection. Some indicators in the water, such as temperature, pH, dissolved oxygen, etc., will change during the sampling process, which will cause the measured value to deviate from the real value and affect the final water quality. sample testing interest
