Description

Portable multi-point layered water sampling device

Technical Field

The utility model relates to a water quality monitoring technical field particularly, relates to a portable multiple spot layering water sampling device.

Background

Water resources are one of the most important natural resources and one of the main emissions in industrial and agricultural production, and water is closely related to ecological environment management and protection and human health. Water quality monitoring is basic work in water environment protection and water pollution control work, and sample collection is an important prepositive link of monitoring work. The effectiveness and convenience of sampling are directly related to the accuracy of the water body physical and chemical index detection result. No matter natural water bodies or water bodies discharged by industrial enterprises, water layers with different depths and different point locations have different water quality physicochemical parameters, so that the collection of samples usually needs multiple point locations and multiple levels. In order to ensure the accuracy of detection work and the requirement of sample reservation comparison, the same monitoring point also needs the collection of a plurality of parallel samples. And also aims to meet the requirements set forth in the standard HJ494-2009 Water quality sampling technical guide.

The traditional emptying water sampler is made of cylindrical organic glass or stainless steel, two semicircular sealing covers which are opened in a single direction are arranged on the upper bottom surface and the lower bottom surface, and the water sampler is opened when sinking and closed when rising. The collection operation is that the water surface is quickly and continuously lifted out by the aid of a traction rope after the water surface is manually sunk to a preset depth, and then the water surface is filled into a collection container. Although the conventional sampling containers for water bodies are made of polyethylene and borosilicate glass, and are various types of narrow-mouth, wide-mouth and bottles with screw caps, the polyethylene plastic bottles with screw caps are commonly used for outdoor operation and convenience in carrying and transportation.

Although the traditional emptying type water sampler has a simple structure, only a water sample with a single point and a single layer depth can be collected in each operation, and the working efficiency of multiple collection is low. The pure mechanical lifting and sealing principle must ensure the continuity of the lifting operation, otherwise, the sealing failure is caused, and the sample collection failure needs to be operated again. Meanwhile, the water surface is lifted out and then needs to be immediately filled into a collection container, otherwise, the sample water body can be rapidly leaked. In addition, the collection work of the parallel sample of current water can't be gone on simultaneously by one person, and the operation of normal position is difficult to guarantee in the collection of parallel sample many times, and is great to stirring of water, probably leads to the result deviation. Due to the defects, the efficiency of the traditional water sample collection work is limited.

Patent document CN103398874A proposes an automatic device and a sampling method for water body layered synchronous sampling. Can realize the layered synchronous sampling of the water body. However, the sampling depth is limited by the supporting round pipe, the sampling device cannot be used in occasions with deeper sampling requirements, the range is small, and the vacuum pump is needed for assistance.

Patent document CN205562216U proposes a water quality monitoring multi-depth sampler. The water quality monitoring sampler capable of sampling a plurality of water depth scales at one time has the advantages of automatic sampling and simple operation. However, the device is large in size and complex in structure, and components such as a stepping motor, a microprocessor, a micro water pump, an electromagnetic valve and a micro printer are needed, so that the device is inconvenient to carry and high in cost.

The patent CN209745617U proposes a water body layered synchronous sampler. Simple structure utilizes the short rope to concatenate a plurality of water samplers and can realize gathering the water sample of the different degree of depth simultaneously. But the device can not satisfy simultaneous collection of parallel samples at the same point, and can not satisfy the requirement that the operation of putting the rope once finishes the collection of multiple spot samples. In addition, the device also can simply realize the water sample collection of arbitrary degree of depth, needs to change the short rope. Therefore, the device is limited in convenience in improving the actual operation.

An effective solution to the problems in the related art has not been proposed yet.
