Description

Technical Field

[0001] The utility model relates to the technical field of total phosphorus detection, and is specifically a water quality sampler suitable for total phosphorus detection. Background Art

[0002] Total phosphorus refers to the total content of phosphorus in water, which is an important indicator to measure the richness of organic matter in water. Excessive intake of phosphorus can cause excessive growth of algae, leading to eutrophication of water bodies and possible algal blooms or red tides, which will disrupt the natural balance of water bodies. In the water environment, phosphorus is a key element for algae growth. Its excessive intake may cause water bodies to deteriorate and stink, and even affect the normal ecosystem of rivers, lakes and reservoirs.

[0003] When the sampler is taken out of the water after sampling, some pollutants such as sewage, sludge, and algae will be attached to its outer surface. Most samplers in the prior art do not have facilities to clean these pollutants. These water-pollutant mixtures have the characteristics of many colonies and foul odors. If these water-pollutant mixtures are not cleaned in time, they can easily drip into the outside and cause pollution. Utility Model Content

[0022] like Figure 1 and Figure 2 As shown, a slide groove 9 is provided on the inner wall of the hollow rod 1, and a block 10 is fixedly connected to the piston 3, and the outer surface of the block 10 slides with the inner wall of the slide groove 9; a piston rod 11 is fixedly connected to the other side of the piston 3, and a pull rod 12 is fixedly connected to the end of the other end of the piston rod 11 that passes through the hollow rod 1; when the pull rod 12 is pulled, the piston rod 11 pulls the piston 3 to move along the direction of the slide groove 9, and the rope 4 pulls the sampling tube 5 into the hollow rod 1; a crank 14 is fixedly connected to the side of the pull rod 12 away from the piston rod 11, and through the matching arrangement of the block 10 and the slide groove 9, when the crank 14 is turned, the piston rod 11 rotates with the piston 3, and the block 10 presses against the slide groove 9 to rotate the hollow rod 1.

[0023] like Figure 2 As shown, a solenoid valve 8 is provided on the side wall of the sampling tube 5 . When the solenoid valve 8 is opened, external water enters the sampling tube 5 through the solenoid valve 8 , thereby achieving sampling of the sampling tube 5 .

[0024] When the device is in use, Figure 1 and Figure 2As shown, by setting the rope 4, the hollow rod 1 is swung to swing the sampling tube 5 into the water at a distance, so that the device can sample at a long distance; then the solenoid valve 8 is opened, and the water enters the sampling tube 5 through the solenoid valve 8, so that the sampling of the sampling tube 5 is realized; it should be noted that during the descent of the sampling tube 5 in the water, the solenoid valve 8 can be repeatedly opened and closed, so that water at different water levels in the sampling tube 5 can be collected, so as to realize mixed collection of water samples, and the detection of mixed water samples can better reflect the condition of the water body and has higher reliability.

[0025] like Figure 1 and Figure 3 As shown, pulling the pull rod 12 causes the piston rod 11 to pull the piston 3 to move along the direction of the slide groove 9, and the rope 4 pulls the sampling tube 5 up. When the sampling tube 5 rises to jump out of the water, stopping pulling the pull rod 12, placing the rope 4 between the two locking rings 601, starting the electric telescopic rod 603 to extend the telescopic end of the electric telescopic rod 603, and driving the locking ring 601 to rotate.
