Automatic sample reserving device for water

Abstract

The invention discloses an automatic sample reserving device for water. Sample reserving comprises the steps as follows: sample water enters a preparation cup to prepare for sample reserving, after the sample water is prepared, an instruction, i.e., sample reserving or non sample reserving, can be received, if the non sample reserving instruction is received, the preparation cup is automatically emptied and cleaned (comprising actions such as washing and drying), if the sample reserving instruction is received, the water in the preparation cup is conveyed into a specified sample reserving bottle through a transportation device, the purpose of automatic sample reserving of the water is realized, meanwhile, the function of adding a fixing agent in the specified sample reserving bottle is supported, a water sample in the specified sample reserving bottle is fixed so as to prevent the water quality from changing, the automatic sample reserving device for the water can be used for automatically carrying out emptying, cleaning and bottle mouth sealing on sample reserving bottles one by one or selectively according to requirements, the water sample reserving accuracy is high and can be corrected; the sample reserving bottles can be flexibly placed in the manners such as flat paving and stacking, the space occupied by the sample reserving device is saved, and the number of the sample reserving bottles can be self-set. Double emptying design (sample reserving bottle emptying and sample reserving preparation device emptying) is adopted by the sample reserving device, the sample reserving bottles can be cleaned more thoroughly, and the sample reserving effect is extremely good.

Description

technical field [0001] The invention relates to an automatic water quality sample retainer, belonging to the technical field of water quality sample retainers. Background technique [0002] The water quality automatic sampler is a special environmental protection monitoring supporting instrument for total amount control, pollution source investigation and water quality monitoring. It uses advanced driving methods (pumps or vacuums or syringes) to take water and is controlled by a single-chip microcomputer. Users can according to It needs to input such as sampling time interval, sampling volume and sampling method, etc. It can automatically complete the corresponding work online or manually, and can realize the double work of sewage metering and flow rate sampling. After the load cell is connected, the results of the retained samples can be remotely and visually fed back. Widely used in supporting sewage monitoring and surface water monitoring, it is an important component o...
