Description

Technical Field

[0001] The utility model mainly relates to the technical field of water quality detection, in particular to an adjustable fixed-depth water source sampling device. Background Art

[0002] A water quality sampler is a device for collecting water quality samples. There are two types: manual water quality samplers and automatic water quality samplers. The material of the manual water quality sampler must not affect the composition of the water sample, and must be easy to wash, and must not have any residue from the previous sample; the automatic water quality sampler is a bucket-type sampler suitable for flow-proportional storage. It is an intelligent multifunctional suction-type water sample bottle sampling device. It can realize a variety of sampling methods (quantitative sampling, timed quantitative sampling, timed flow ratio sampling, constant flow quantitative sampling and remote control sampling) and a variety of bottling methods according to the water sampling requirements.

[0003] After searching, a deep-water sampling device disclosed in the publication number CN219224236U is found; it includes a sampling box, a battery and an adjustment mechanism are arranged in the sampling box, a sampling mechanism is arranged on the top of the sampling box, the sampling mechanism includes a sampling bottle and a sampling drive mechanism, the adjustment mechanism includes an adjustment motor, an adjustment rod, a fixing sleeve, a threaded rod, a connecting rod and a supporting wheel, and the supporting wheel is slidably connected to the sampling drive mechanism. The utility model can smoothly and accurately move the sampling bottle to the surface above the water required for sampling through the adjustment mechanism, and will not shake greatly and deviate from the sampling point. The sampling drive mechanism lowers the sampling bottle to the depth required for sampling for sampling operation. The engagement of the limit gear block and the rotating gear can ensure that the sampling bottle can be sampled smoothly at the required sampling depth, and avoid the sampling bottle from continuing to drop during the sampling process. The sampling bottle can ensure that the water sample collected is the water sample of the depth to be measured, thereby ensuring the authenticity and reliability of the deep-water sampling detection data.

[0004] In the above technical solution, the sampling motor is started to make the sampling bottle drop to the optimal sampling depth for sampling operation, which makes the sampling operation more convenient, thereby improving work efficiency. At the same time, the engagement of the limit gear block and the rotating gear can prevent the sampling bottle from continuing to drop when it drops to the sampling depth for sampling operation. The sampling mechanism makes the sampling bottle in a stable state during sampling, which is convenient for subsequent sampling operations. However, during use, the above solution cannot complete the sampling of water sources of different depths at one time, and needs to be retracted and released multiple times for sampling, which is time-consuming and labor-intensive, reduces practicality, and brings trouble to the staff. Therefore, we provide an adjustable fixed-depth water source sampling device to solve the defects existing in the above solution. Utility Model Content
