Public place water quality sampler

Abstract

According to the public place water quality sampler, a bottle sleeve and a sealing film are arranged outside an adopted sampling bottle, the joint of the bottle sleeve and an annular groove of a communication module is separated during multiple times of sampling, it is guaranteed that a sampling bottle opening is located in the communication module during sampling, and the situation that a water sample is directly irradiated by sunlight is also avoided; a disposable sealing film is arranged at a bottle opening, and an air suction pipe and a stabilizer spray pipe are communicated with a sampling bottle in a puncturing manner, so that insufficient air tightness in the bottle during air pumping of an air suction pump is prevented, and the sampling bottle is prevented from being polluted by bacteria in an external environment during sampling, and a telescopic sampling rod and a servo motor positioned at the end part of the telescopic sampling rod are also adopted; the telescopic sampling rod and the servo motor are controlled to zoom through a roller switch, and the extension lengths of the the telescopic sampling rod and the servo motor and the lowering depth of the lifting line can be observed through a display screen, so that the accuracy of multi-point sampling is ensured, and the influence of an operation error of a worker on a sampling result is reduced; the problems that workers are difficult to strictly sample according to specifications in different environments and the health is easily harmed are solved.

Description

technical field [0001] The invention relates to the field of sanitation water body detection technology, and more specifically, to a water quality sampler for public places. Background technique [0002] When testing environmental sanitation water bodies, it is often necessary to carry out aseptic sampling operations on various water bodies to ensure the accuracy of the sample results. Sampling of Legionella pneumophila in air-conditioning cooling towers; sampling of swimming pool water bodies. Due to the varying degrees of pollution and environmental conditions of these water bodies, it is difficult to ensure aseptic operation in actual sampling, and there is still a risk of health hazards to the sampling personnel. In addition, there are often requirements for water depth and multi-point sampling during the collection of sanitation water bodies. For example, hospital sewage is often collected in sewage wells, and multiple samples are collected at a distance greater than 15...

Problems solved by technology

[0004] In view of the above defects or improvement needs of the prior art, the present invention provides a water quality sampler in public places, which adopts a telescopic sampling rod and a servo motor at its end, both of which are controlled by a roller switch to zoom, and the two Both the elongation length and the lowering depth of the lifting wire can be observed through the display screen, which ensures the accuracy of multi-point sampling, reduces the difficulty of remote sampling for operators and the health threat to personnel from the sampling environment, and reduces the impact of personnel operation errors on sampling The infection of the results solves the problem that it is difficult for staff to strictly follow the specifications for sampling and the health is easily endangered in different environments
