Description

Technical Field

[0001] The utility model relates to the technical field of sampling devices, in particular to a sampling device for water pollution. Background Art

[0002] Water quality testing is to determine the types of pollutants in water bodies, the concentration of various pollutants, and evaluate the water quality. The testing scope is very wide, including unpolluted and polluted natural water (rivers, lakes, seas and groundwater) and various industrial drainage, etc. Water resources are the most important natural resources in human society. In order to facilitate the testing of water quality, sampling devices are needed to sample water resources.

[0003] The common sampling devices for monitoring water pollutants on the market usually require the use of a stirring rod to stir the water in the water storage barrel when extracting water from the water storage barrel to be tested, so that the precipitated substances to be tested can be fully mixed in the water to be sampled. This can more accurately detect the quality of the water, resulting in a cumbersome sampling process and the need to store and find the stirring rod separately, which to a certain extent increases the management difficulty and detection efficiency of the staff. Utility Model Content

[0004] In view of this, the utility model provides a sampling device for water pollution, which can stir the water during the sampling process by rotating a stirring component for stirring the water to be tested at the bottom of the sampling tube, without the need to find a stirring rod for stirring, which greatly reduces the management difficulty of the staff and improves the detection efficiency of the staff.

[0005] In order to solve the above technical problems, the utility model provides a sampling device for water pollution, including a sampling barrel, a liquid extraction component for extracting water to be tested is arranged inside the sampling barrel, a liquid extraction tube connected to the sampling barrel is arranged at the bottom, a stirring component for stirring the water to be tested is rotatably arranged on the outer side of the liquid extraction tube, and the stirring component includes a rotating part sleeved on the outer side of the liquid extraction tube, and a plurality of stirring blades are evenly hingedly arranged on the outer side wall of the rotating part. The utility model can achieve stirring of water during the sampling process by rotatably arranging the stirring component for stirring the water to be tested at the bottom of the sampling barrel, without the need to find a stirring rod for stirring, which greatly reduces the management difficulty of the staff and improves the detection efficiency of the staff.

[0006] The rotating part is a bearing, which is a ball bearing, and both the ball and the bearing are made of corrosion-resistant plastic material. The friction between the ball and the inner ring of the bearing is sufficient to ensure that when the sampling tube is moved, the ball can rotate with the outer ring of the bearing and the stirring blade. The inner ring of the bearing is fixed to the outer wall of the liquid extraction tube, and the stirring blade is hinged on the side wall of the outer ring of the bearing through a universal joint. The universal joint is a plastic joint, and the stirring blade is a plastic blade. The utility model can use a stirring component made of plastic material to achieve that when the sampling tube is extended into the water storage barrel to be tested, the impact force of the water can push the outer ring of the bearing to swing and rotate with the ball, the universal joint and the stirring blade, thereby achieving the stirring operation of the water to be sampled. If necessary, in order to improve the homogenization efficiency of the water, the sampling tube can be manually twisted to rotate within a certain range.

[0007] The liquid extraction component includes a piston slidably arranged inside the sampling cylinder. A flange is arranged on the upper part of the sampling cylinder to facilitate the operator to press or grasp it. A scale is arranged on the outer wall of the sampling cylinder to facilitate the operator to observe the amount of sampled water. A push rod is arranged on the upper part of the piston. The utility model can realize the extraction of water to be tested in the water storage barrel by pushing and pulling the push rod manually, which is more convenient and labor-saving.

[0008] A filter plate is clamped at the bottom of the inner wall of the sampling cylinder, and a limit rod is arranged on the filter plate. A limit cylinder matched with the limit rod is arranged at the lower part of the piston and on the axis of the limit rod. The utility model can filter and block solid impurities of the water quality to be tested that enters the sampling cylinder through the filter plate to prevent them from entering the sampling cylinder and affecting the accuracy of the test data. When the filter plate on the upper part of the liquid extraction tube is blocked, the limit cylinder at the lower part of the piston can be pushed by pushing the push rod to insert it into the limit rod, and then the push rod can be rotated clockwise or counterclockwise. Due to the clamping effect of the limit cylinder and the limit rod, the rotating push rod will rotate the piston and the filter screen to a certain angle, thereby realizing the rotation of the unblocked filter screen to the top of the liquid extraction tube, and the sampling operation can be continued.

[0009] In summary, compared with the prior art, the present application includes at least one of the following beneficial technical effects:

[0010] 1. The utility model can achieve the stirring operation of water during the sampling process by rotating a stirring component for stirring the water to be tested at the bottom of the sampling tube, without the need to find a stirring rod for stirring, which greatly reduces the management difficulty of the staff and improves the detection efficiency of the staff.

[0011] 2. The utility model can realize the stirring component made of plastic material when the sampling tube is inserted into the water storage barrel to be tested. Due to the impact force of the water, the outer ring of the bearing can be driven to swing and rotate with the ball, the universal joint and the stirring blade, thereby realizing the stirring operation of the sampled water. If necessary, in order to improve the homogenization efficiency of the water, the sampling tube can be manually twisted to rotate within a certain range.

[0012] 3. The utility model can realize the operation of extracting the water to be tested in the water storage barrel by manually pushing and pulling the push rod, which is more convenient and labor-saving.

[0013] 4. The utility model can filter and block solid impurities of the water quality to be tested that enter the sampling tube through the filter plate, so as to prevent them from entering the sampling tube and affecting the accuracy of the test data. When the filter plate on the upper part of the liquid extraction tube is blocked, the push rod can be used to push the limit tube at the lower part of the piston into the limit rod, and then the push rod can be rotated clockwise or counterclockwise. Due to the clamping effect of the limit tube and the limit rod, the rotating push rod will rotate the piston and the filter screen to a certain angle, thereby realizing the rotation of the unblocked filter screen to the top of the liquid extraction tube, and the sampling operation can be continued.

[0021] According to one embodiment of the utility model, Figure 1-4 As shown, the rotating part 301 is a bearing, and the bearing is a ball bearing, and the ball and the bearing are both made of corrosion-resistant plastic material. The friction between the ball and the inner ring of the bearing is sufficient to rotate the ball with the outer ring of the bearing and the stirring blade 302 when the sampling tube 100 is moved. The inner ring of the bearing is fixedly arranged on the outer wall of the liquid extraction tube 101, and the stirring blade 302 is hingedly arranged on the side wall of the outer ring of the bearing through a universal joint. The universal joint is a plastic joint, and the stirring blade 302 is a plastic blade.
