Water quality sampler

Abstract

The invention relates to the technical field of a water quality monitoring accessorial device, in particular to a water quality sampler. In order to solve the technical problem, the invention providesthe water quality sampler, which is time-saving and labor-saving, reduces working difficulty, improves adaptability, improving working efficiency, is simple to operate, reduces damage and reduces uselimitation. The water quality sampler comprises an organic glass bottle, a nylon rope, a balancing weight and a metal protective cover; a graduated scale is arranged on the outer side wall of the organic glass bottle; the water quality sampler comprises a bottom plate, a top plate, a left side plate, a right side plate, a driving shaft, a driven shaft, a sliding sleeve rod, a supporting column, afirst sleeve, a second sleeve, a third sleeve, a fourth sleeve, a fifth sleeve, a telescopic motor, a screw rod, an adjusting block, a lifting motor, a fixed pulley and an electric control box; the water quality sampler also comprises an electromagnetic valve and a metal filter screen; the electromagnetic valve is arranged at the top end of the organic glass bottle; the electromagnetic valve is electrically connected with the electric control box; the metal filtering net is positioned below the electromagnetic valve; and the metal filter screen is arranged in a cavity.

Description

technical field [0001] The invention relates to the technical field of water quality monitoring attachments, in particular to a water quality sampler. Background technique [0002] As we all know, the quality of water sources and water quality is directly related to the development of the national economy and people's physical and mental health. Water quality testing and analysis is one of the important contents of the national environmental protection supervision and monitoring work, especially for water areas affected by sewage discharge. Analysis is more important, and water quality sampler is a kind of used, and it has been widely used in the field of water quality monitoring; Existing water quality sampler includes organic glass bottle, nylon rope, counterweight and metal protective cover, organic glass The inside of the bottle is provided with a cavity, the top of the plexiglass bottle is provided with a water inlet, and the water inlet communicates with the cavity, th...

[0002] As we all know, the quality of water sources and water quality is directly related to the development of the national economy and people's physical and mental health. Water quality testing and analysis is one of the important contents of the national environmental protection supervision and monitoring work, especially for water areas affected by sewage discharge. Analysis is more important, and water quality sampler is a kind of used, and it has been widely used in the field of water quality monitoring; Existing water quality sampler includes organic glass bottle, nylon rope, counterweight and metal protective cover, organic glass The inside of the bottle is provided with a cavity, the top of the plexiglass bottle is provided with a water inlet, and the water inlet communicates with the cavity, the outer wall of the plexiglass bottle is provided with a scale, the counterweight is installed at the bottom of the metal protective cover, and equipped with The top of the weight is connected to the bottom of the metal protective cover, and one end of the nylon rope is connected to the top of the metal protective cover; when the existing water quality sampler is used, the water quality inspector takes the other end of the nylon rope and the pull cord, and then selects At the sampling site, put the plexiglass bottle into the water area of ​​the sampling site, and sink naturally through the counterweight. After sinking to a certain height, the water quality inspector pulls the pull rope to pull the end cover away, and the tested water enters the plexiglass In the bottle, the nylon rope drives the metal protective cover to lift the plexiglass bottle, and the sampling depth is measured through the wet position of the nylon rope; it is found in the use of existing water quality samplers that in daily surface water quality monitoring and sampling, the sampling locations are mostly located on bridges. In order to make the sampling results more accurate, it is necessary to collect water samples at different distances from the bridge or shore. Sometimes it is necessary to extract samples at multiple levels, which is time-consuming and labor-intensive, which adds great difficulty to the water quality testing personnel. The ability is poor and the work efficiency is low; and it is troublesome to pull the end cap by the pull rope, and it is often unable to pull it open, resulting in sampling failure. At the same time, the opening of the top of the plexiglass bottle is large, and it is easy to flow large particles of impurities contained in the measured water into the bottle. inside, resulting in damage to the plexiglass bottle, which affects normal use and has high limitations in use
