Description
Technical Field
[0001] The utility model relates to the technical field of water quality sampling, in particular to a water sampler. Background Art
[0002] Water pollution is one of the forms of environmental pollution, which is mainly caused by pollutants produced and used by people in the development of the times. Polluted water is extremely harmful to our bodies and the crops we grow. If we want to treat water, we must regularly test the water quality. By mastering the various parameters in the sewage, we can develop more accurate and targeted treatment plans to ensure that the water quality meets the standards and improve people's quality of life.
[0003] After searching, the Chinese patent with announcement number: CN210322419U discloses a water sampler, including an outer frame and an inner frame, the upper end of the inner frame is fixedly connected with an upright connecting rod, the upper end of the connecting rod is connected to a float ball through a first pull rope, the lower end of the inner frame is provided with a first clamp for fixing the sampling bottle body, the upper end of the outer frame is sleeved on the connecting rod, the lower end of the outer frame is provided with a counterweight block, and the upper end surface of the counterweight block is provided with a second clamp for fixing the sampling bottle plug, the lower end of the sampling bottle body is provided with a sampling port, and the upper end of the sampling bottle body is tightened to form an exhaust nozzle, and when the outer frame moves up and down along the connecting rod, the sampling port and the bottle plug above the counterweight block can be separated and closed. The water sampler of the utility model has a simple structure, is easy to use, and can accurately collect water samples to a specific depth.
[0004] The working principle of the above-mentioned patent mentions that "the sampling depth of the sampler is determined by adjusting the length of the first pull rope 2, the float 1 is placed on the water surface, and the rest of the sampler sinks into the water. In the initial state of sinking, the sampling bottle body 50 fixed by the first clamp 40 at the lower end of the inner frame 20 sinks together with the sampling bottle plug 53 fixed by the second clamp 60 at the lower end of the outer frame 10, and at this time, the sampling bottle plug 53 seals the sampling port 52. When it sinks to the sampling depth, under the buoyancy of the float 1, the first pull rope 2 pulls the inner frame 20 to stop the inner frame 20 from sinking. At this time, the outer frame 10 sleeved on the connecting rod 30 continues to sink under the action of the counterweight 70 until its top collides with the inner frame 20. The sampling bottle plug 53 is separated from the sampling bottle body 50 under the drive of the outer frame 10. At this time, the sampling port 52 is opened, water enters from the sampling port 52, and air is discharged through the exhaust nozzle 51. When the water sampling is completed, the outer frame is lifted The outer frame 10 first moves upward along the connecting rod 30, so that the sampling bottle plug 53 is embedded in the sampling port 52. At this time, the sampling port 52 is sealed, and the inner frame 20 and the sampling bottle body 50 fixed on the inner frame 20 by the first clamp 40 move with the outer frame 10 until it is raised to the surface of the water. The staff opens the first clamp 40 and the second clamp 60, and can remove the sampling bottle body 50 together with the sampling bottle plug 53, so that it is convenient for the staff to send the water sample for inspection. "However, in the above document, since the sampling bottle body is fixed in the inner and outer frames by clamping, the sampling bottle body and the sampling bottle plug need to be removed after the water sample is collected. This is not only troublesome, but also easy to cause the sampling bottle plug to loosen while removing, resulting in the outflow of the sample. In addition, since the rope connected to the float ball cannot be adjusted, the sampling bottle can only be used to sample water samples at a fixed position. In view of the above problems, a water sampler is proposed to solve the above problems. Utility Model Content

The user can easily remove the bottom cover 7 through the hole of the bottom cover 7 to clean the inner wall of the sampling cylinder 1.
[0032] Working principle: When the user needs to sample the sampling tube 1 at a fixed water depth, first use the push rod 2 to drive the piston 3 to squeeze it to fit with the top of the bottom cover 7, evacuate the air inside the sampling tube 1, and then pull the rope 9 placed in the storage box 10 to pull the rope 9 to the required length, and then fix the bottom end of the rotating block 18 on the threaded rod 20 by rotating the clamp ring 21. During the rotation of the clamp ring 21, the rotating block 18 will gradually be driven to rotate against the inner wall of the limit block 17, so that the clamp block 2 16 on the top of the limit block 17 cooperates with the clamp block 1 15 to squeeze and rub the outside of the rope 9 to fix it, so as to fix the length of the rope 9. At this time, the entire sampling tube 1 can be When the sampler is placed on the water surface, the part of the sampling tube 1 of the sampler will gradually sink due to gravity. During the sinking process, the water flow will impact the rotating cover 8 of the bottom cover 7 inside the sampling tube 1, so that the water in the middle hole of the bottom cover 7 flows into the interior of the sampling tube 1 and presses the piston 3 in the sampling tube 1 to slide to the top of the inner wall of the sampling tube 1. At this time, due to the buoyancy of the float 13, the sampling tube 1 will gradually sink until the rope 9 is pulled to stop sinking. Finally, the float 13 can be picked up, and the sampling tube 1 can be pulled to take the entire sampler out of the water. During this process, when the sampling tube 1 is pulled, the water sample inside the sampling tube 1 will press the rotating cover 8 on the bottom cover 7 to block the hole of the bottom cover 7. After completing the above operations, the sampling is successful.
[0033] When the user needs to clean the inner wall of the sampling tube 1, the pull rod 26 can be moved to drive the rotating shaft 27 and the hook 28 to rotate, thereby loosening the hook 28, and then the hook 28 can be moved to disengage the hook 28 from the engagement with the hole 29 and the hole 30. The user can then remove the bottom cover 7 through the hole in the bottom cover 7 to clean the inner wall of the sampling tube 1.
[0034] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
