[0002] When conducting environmental pollution monitoring, sampling is an essential operation. Common sampling includes air sampling, soil sampling, and water sampling. Among them, water sampling is often the most cumbersome and important operation. In today's society, due to a series of reasons such as excessive use of resources and environmental damage, water pollution is worsening. In addition to domestic wastewater, sewage discharged by factories and enterprises is the main cause of water pollution. Through perfect water quality testing technology, it will be an important means to curb water pollution and protect the source of human life. By sampling and testing water bodies in chemical water environments, it can accurately, timely and comprehensively reflect the current status and development trends of water quality, provide a scientific basis for water environment management, pollution source control, environmental planning, etc., and play an important role in the protection of the entire water environment, water pollution control, and maintaining the health of the water environment.

DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] Reference Figure 1-Figure 5 A sampler for chemical water environment detection, comprising a shell 1 and a frame 4, the frame 4 is fixedly mounted on the surface of the shell 1, the frame 4 comprises three sets of telescopic mechanisms, each telescopic mechanism comprises a first fixed shaft 5, a movable rod 1 6, a movable rod 2 7, a spring inner rod 10, a spring 11, a block 9, the first fixed shaft 5 is fixedly mounted on the surface of the frame 4, the movable rod 1 6 is rotatably connected to the first fixed shaft 5, the upper surface of the movable rod 2 7 is fixedly mounted with a movable shaft 1 8, the movable rod 1 6 is rotatably mounted on the movable shaft 1 8, the surface of the block 9 Two soft plugs 17 are fixedly installed, and the block 9 is slidably sleeved on the outside of the spring inner rod 10. The two ends of the spring inner rod 10 are respectively fixedly connected to the inner surfaces of the two sides of the frame 4, one end of a spring 11 is fixedly connected to the inner surface of the frame 4, and the other end of a spring 11 is fixedly connected to the surface of the block 9. A brake line is installed on the surface of each movable shaft 8. The brake line includes a wire core 12 and a wire tube 13. The wire tube 13 is slidably connected to the wire core 12. A fixing frame 14 is fixedly installed on the top of the frame 4, and the fixing frame 14 and the wire tube 13 are fixedly connected.

[0020] One end of each wire tube 13 away from the movable shaft 8 is fixedly connected to a handle 19, a support rod 23 is fixedly connected to the handle 19, a rotating shaft 24 is fixedly installed on the support rod 23, a rocker 18 is rotatably connected to the rotating shaft 24, and one end of each wire core 12 away from the movable shaft 8 is fixedly connected to the rocker 18. The rocker 18 rotates through the rotating shaft 24 on the support rod 23, thereby adjusting the movement of the wire core 12, and then adjusting the movable shaft 8 and the soft plug 17 on the block 9 through the wire core 12, realizing the control of the opening and closing of the water storage chamber 15, and completing water storage.

[0021] A spring 25 is provided between each rocker 18 and the handle 19. One end of the spring 25 is fixedly connected to the rocker 18, and the other end of the spring 25 is fixedly connected to the surface of the handle 19. The spring 25 is a soft spring, which ensures that the distance between the rocker 18 and the handle 19 is maximized so that the water storage chamber 15 is in an open state.

[0022] A counterweight 2 is fixedly mounted at the bottom of the housing 1. The shape of the counterweight 2 is set to be conical. When the housing 1 is to be placed in water, the conical counterweight 2 can ensure that the housing 1 is in a vertical state and is easy to put into the water.

[0023] The water storage chamber 15 is fixedly connected with two water pipes 16 to ensure that water can flow smoothly into the water storage chamber 15 when sampling, and it will be faster when pouring out the sampled water.

[0024] A ring is fixedly mounted on the top of the handle 3. When the housing 1 is thrown into water, a rope can be tied to the ring, so that the housing 1 can be easily controlled underwater.

[0025] Before use, the buckle 22 is buckled onto the second fixed shaft 20, thereby locking the rocker 18, and then the housing 1 is placed in the water body that needs to be sampled. When the first height required for sampling is reached, the buckle 22 and the second fixed shaft 20 are disengaged, and the line core 12 is no longer tightened. The line core 12 begins to slide in the line tube 13, and the movable shaft 8 loses the tension control of the line core 12. At this time, the movable rod 16 rotates along the first fixed shaft 5, and the movable rod 27 rotates around the movable shaft 26. The spring 11 lifts the block 9, and the soft plug 17 fixed on the surface of the block 9 leaves the water pipe 16 of the water storage chamber 15. At this time, the water storage chamber 15 begins to fill with water. After the water fills the water storage chamber 15, the rocker 18 and the handle 19 are held by hand, thereby driving the line core 12 to start sliding in the line tube 13. The line core 1 2 pulls the movable shaft 1 8, and the movable shaft 1 8 moves upward, driving the movable rod 2 7 to rotate, and the movable rod 2 7 drives the movable shaft 2 26, so that the block 9 moves along the spring inner rod 10, close to the water pipe 16, and drives the soft plug 17 to block the water pipe 16. After completing one water sampling, hold the rocker 18 and the handle 19, rotate the buckle 22, so that the buckle 22 and the second fixed shaft 20 are relatively fixed, and the closure of a water storage chamber 15 is completed. Repeat the above process, by adjusting different rockers 18 and handles 19, water sampling at different depths can be completed. After completing the water sampling at three depths, take the shell 1 out of the water, and put the obtained water samples into the container respectively in turn. The shell 1 can be put into the water once to sample water at three different depths, and the operation is simple and convenient.

[0026] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
