Description

A water quality monitoring and analysis sampling device Technical Field

[0001] This utility model relates to the technical field of water quality sampling tools, and in particular to a water quality monitoring and analysis sampling device. Background Technology

[0002] Water quality monitoring is the process of systematically detecting and evaluating physical, chemical, and biological indicators in water bodies. It aims to understand the water quality status, pollution level, and trends of change, providing a scientific basis for water resource protection, pollution control, and ecological management.

[0003] When monitoring water quality, it is necessary to take water samples. Sampling buckets are commonly used for sampling. The sampling bucket is placed in the water, and after automatic water intake, it is lifted out of the water to complete the sampling. Depending on the water depth and the conditions of the sampling location, a rope is needed to suspend the sampling bucket. The existing ropes are fixed to the sampling bucket by knots, which are prone to loosening when submerged in water. The ropes are fixed to the collectors by gripping, which is prone to loss of strength and loosening. The fixing methods at both ends of the rope are also prone to loosening, causing the sampling bucket to fall into the water, which is inconvenient for water quality sampling. Summary of the Invention

[0004] The purpose of this utility model is to provide a water quality monitoring and analysis sampling device in order to solve the above-mentioned problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1: As shown in Figures 1-4, a water quality monitoring and analysis sampling device includes a sampling bucket 1, a lifting rod 2, and a rope 3. The top of the sampling bucket 1 is connected to the lifting rod 2, and the lifting rod 2 is connected to the rope 3. A flip-top for water inlet is movably installed inside the top of the sampling bucket 1. A water inlet piston is also provided inside the sampling bucket 1. The water inlet piston is existing technology and will not be described in detail here. A water outlet 11 is provided at the bottom of the sampling bucket 1. A connector for fixing the rope 3 is connected to the lifting rod 2. The connector includes a rope clamp 4, a stud 5, a threaded half-cylinder 6, and a threaded cylinder 7. The rope clamp 4 is a two-piece type, each piece is bow-shaped. The threaded half-cylinder 6 is fixedly connected to the bottom of the corresponding rope clamp 4. The two threaded half-cylinders 6 form a complete nut. The threaded cylinder 7 is fixedly connected to the lifting rod 2. One end of the stud 5 is connected to the two... The threaded half-cylinder 6 is threaded, and the other end of the stud 5 is threaded to the threaded cylinder 7. Two rope clamps 4 are arranged in mirror symmetry. The inner side of the arc of the rope clamp 4 is provided with a fixing pin 42. The fixing pin 42 is inserted into the bottom end of the rope 3. The two ends of the two rope clamps 4 are fixedly connected by bolts 41. The top of the rope 3 is provided with a male hook and loop fastener 31 and a female hook and loop fastener 32. The male hook and loop fastener 31 and the female hook and loop fastener 32 are set together. The outer end of the fixing pin 42 is conical, which makes it easy to insert into the rope 3. Through the cooperation of the rope clamps 4, stud 5, threaded half-cylinder 6 and threaded cylinder 7, the rope 3 and the sampling bucket 1 can be stably connected and will not loosen due to water immersion. Through the adhesive force of the male hook and loop fastener 31 and the female hook and loop fastener 32, the rope 3 is firmly wrapped around the collector's hand and will not slip off even when the hand is weak.

[0024] Working principle: When sampling water quality, first install and fix the rope 3 to the sampling bucket 1. Specifically, first screw the stud 5 onto the threaded cylinder 7, then insert the end of the rope 3 without the female hook and loop fastener 31 and female hook and loop fastener 32 into the rope clamp 4, with the fixing pin 42 inserted into the rope 3. Hold the rope clamp 4, and then use the bolt 41 to fix the two rope clamps 4 together. At this time, the two threaded half cylinders 6 form a complete nut, which is screwed together with the other end of the stud 5. At this time, the fixed connection between the rope 3 and the sampling bucket 1 is completed. Next, wrap the end of the rope 3 with the female hook and loop fastener 31 and female hook and loop fastener 32 around the collector's hand, and stick the female hook and loop fastener 31 and female hook and loop fastener 32 together. At this time, the fixed connection between the rope 3 and the collector's hand is completed.

[0025] Next, sampling bucket 1 is dropped into the water. Sampling bucket 1 begins collecting water samples. Specifically, when sampling bucket 1 is placed in the water, the bottom inlet piston opens due to downward pressure, allowing water to continuously enter the water sampler. When sampling bucket 1 is full of water, the water flows out from the top flap due to downward pressure until sampling bucket 1 reaches the sampling position. Water always enters from the bottom and flows out from the flap. When the flap reaches the position where water samples are to be collected, sampling bucket 1 is lifted upwards. Due to downward pressure, the inlet piston and flap will automatically close, preventing water from entering or flowing out of sampling bucket 1, thus achieving the sampling purpose.

[0026] Finally, pull rope 3 to completely lift sampling bucket 1 out of the water. Then, after carrying sampling bucket 1 to the water quality testing room, you can open the outlet 11 to release water.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
