Problems solved by technology
[0003] When the relevant departments test the water quality in water sources such as lakes, the samplers are required to extract the water source at the outlet sampling point, but the water sample collection device can only be sampled once after it is launched, so the sampler needs to continue to retract and release the collection device. The collection of water samples at different depths will lead to a large workload for the samplers, cumbersome operations, and low sampling efficiency. Once encountering relatively hot weather, it will affect the personal health of the samplers

Embodiment Construction
[0031] see Figure 1-5 An automatic sampling machine for environmental monitoring water quality samples, comprising a main body 11, two sliding blocks 16, a rotating head 18, a sampling rod 20, a pull cord 22, a sampling bucket 23, a tightening mechanism, a stabilizing mechanism and a fixing groove 31.
[0032] The main body 11 is provided with a sample receiving cavity 12, and the distance between the front and rear walls of the sample receiving cavity 12 gradually decreases from left to right. The front and rear sides of the sample receiving cavity 12 are connected with a sliding cavity 13, and the number of the sliding cavity 13 is two , the two sliding blocks 16 are slidably arranged in the front and rear two sliding chambers 13 respectively, the rotating head 18 is rotatably connected to the end faces of the front and rear two sliding blocks 16 close to each other, and the two rotating heads 18 are provided with a shrinking cavity 19 on the side close to each other , the ...

The invention discloses an automatic sampling machine for environmental monitoring water quality samples, and belongs to the field of sampling machines. An automatic sample collecting machine for environmental monitoring water quality samples comprises a main body, two sliding blocks, a rotating head, a sample collecting rod, a pull rope, a sampling barrel, a tightening mechanism, a stabilizing mechanism and a fixing groove, a sample collecting cavity is formed in the main body, the distance between the front wall and the rear wall in the sample collecting cavity is gradually reduced from left to right, and two sliding cavities are formed in the front side and the rear side of the sample collecting cavity in a communicating mode; according to the scheme, the sampling barrel is quickly retracted in a manner of driving the sampling barrel to ascend by the retracting and sampling rod and the pull rope, so that the sampling efficiency is improved, and the pull rope on the outer surface of the sampling rod is extruded in a manner of driving the rotating head to move rightwards by the two sliding blocks while the sampling barrel is retracted, so that the sampling barrel is quickly retracted, and the sampling efficiency is improved. Stay cord drying is accelerated, and the service life of the stay cord is prolonged.
Description
technical field [0001] The invention relates to the field of sample collectors, in particular to an automatic sample collector for environmental monitoring water quality samples. Background technique [0002] Water sample monitoring refers to the monitoring of physical properties of environmental water bodies (rivers, rivers, lakes, reservoirs and groundwater, etc.) monitoring, monitoring of organic compounds, biological monitoring and determination of hydrological and meteorological parameters, and geological monitoring. [0003] When the relevant departments test the water quality in water sources such as lakes, the samplers are required to extract the water source at the outlet sampling point, but the water sample collection device can only be sampled once after it is launched, so the sampler needs to continue to retract and release the collection device. The collection of water samples at different depths leads to a large workload for the samplers, cumbersome operations...
