Description

Technical Field

[0001] This utility model relates to the field of water quality testing technology, and in particular to a water quality stratification synchronous water sampler device. Background Technology

[0002] Water is the most basic substance essential for the survival of all life on Earth and indispensable for human production and daily life. Different uses of water require different quality standards. National regulations stipulate requirements for the physical, chemical, and biological properties of various types of water. Depending on the purpose of water supply, there are standards for drinking water quality, agricultural irrigation water quality standards, etc. The standards for water quality also vary for different industrial production processes. When studying or tracking water quality and the migration and transformation of pollutants in water bodies, we need to sample and test the water. Because water quality varies at different depths, sampling is necessary at different depths during testing.

[0003] In the prior art, patent CN208223883U discloses a water quality stratification synchronous water sampler device. This device comprises a multi-hole sampling box, sampling bottles, and a negative pressure equalization system. The multi-hole sampling box is connected to the inlet of the sampling bottle via a serpentine water pipe, and the air extraction port of the sampling bottle is connected to the negative pressure equalization system via a pressure-resistant pipe. The multi-hole sampling box has 10-30 vertically spaced sampling pipes centrally located within its body. The sampling bottle has an inlet with a valve on its side wall, connected to the serpentine water pipe. An air extraction port is located on the side wall of the sampling bottle near the bottle neck, connected to the negative pressure equalization system via a pressure-resistant pipe. The negative pressure equalization system consists of a negative pressure distribution box, a negative pressure equalization box, and a vacuum pump, connected sequentially via pressure-resistant pipes. A valve is also connected to the pressure-resistant pipe between the negative pressure distribution box and the negative pressure equalization box.

[0004] However, the water sampler in the above scheme is large in size, which makes it extremely inconvenient to put it into the water for sampling. It even requires the use of floating tools such as carrier ships for assistance, and it is time-consuming, labor-intensive and wastes working time. Utility Model Content

[0005] In view of the above-mentioned shortcomings in the existing technology, the present invention provides a water quality stratification synchronous water sampler device. The purpose is to solve the problems of existing water samplers being too large, which makes it extremely inconvenient to put them into the water for sampling, and even requires the use of floating tools such as carrier boats for assistance, and is time-consuming, labor-intensive and wasteful of working time.

[0006] To achieve the aforementioned objectives, the technical solution adopted by this utility model is as follows:

[0007] A water quality stratification synchronous water sampler device includes a hanger, on which a plurality of water sampling buckets are arranged in a circular array. The top of each water sampling bucket has a water inlet, and the bottom of each water sampling bucket is threaded with a screw. A knob is fixedly connected to the bottom of the screw. A sliding plate is slidably connected inside the water sampling bucket. The end of the screw away from the sliding plate is rotatably connected to the sliding plate. A float is installed inside the water inlet, and a spring is installed between the sliding plate and the float.

[0008] Furthermore, a lifting ring is threadedly connected to the top of the hanger.

[0009] Furthermore, a connecting rope is fixedly connected between several of the water collection buckets, and a hook is fixedly connected to the bottom of the connecting rope, with a counterweight attached to the hook.

[0010] Furthermore, a sealing ring is provided between the sliding plate and the water collection bucket.

[0011] Furthermore, the water inlet is shaped like an inverted funnel.

[0012] Furthermore, the hanger is fixedly connected to the top of the water collection tank.

[0013] The beneficial effects of this utility model are as follows:

[0014] This utility model discloses a water quality stratification synchronous water sampler device. According to different underwater pressures, the compression of the spring is adjusted to lower the water sampler into the water. During the descent of the water sampler, water is collected from different water layers. This device is small in size, simple in structure, and easy to use. Attached Figure Description

[0019] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. Identical components are indicated by the same reference numerals.

[0020] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions shown in the attached diagram, while the terms “inside” and “outside” refer to the directions toward or away from the geometric center of a specific component, respectively.

[0021] To make the content of this utility model easier to understand, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0022] like Figures 1 to 2 As shown, a water quality stratification synchronous water sampler device includes a hanger 1 with a lifting ring 8 threadedly connected to the top of the hanger 1. When sampling water, a winch or connecting rope is used to fix the wire rope of the winch or connecting rope to the lifting ring 8, and the hanger 1 is placed in the water and slowly lowered.

[0023] The hanger 1 is equipped with several water collection buckets 2 arranged in a circular array. The hanger 1 is fixedly connected to the top of the water collection buckets 2. The top of the water collection buckets 2 is provided with a water inlet 3, which is shaped like an inverted funnel.

[0024] The bottom of the water collection bucket 2 is threaded with a screw 4, and the bottom of the screw 4 is fixedly connected with a knob 5. The water collection bucket 2 is slidably connected with a sliding plate 6. The end of the screw 4 away from the sliding plate 6 is rotatably connected to the sliding plate 6. A float ball 7 is installed in the water inlet 3. A spring 13 is installed between the sliding plate 6 and the float ball 7. A sealing ring 12 is installed between the sliding plate 6 and the water collection bucket 2.

[0025] Before the water sampling bucket 2 is placed in the water, turn the knob 5. The knob 5 drives the screw 4 to rotate, and the screw 4 drives the slide plate 6 to move up and down. The slide plate 6 compresses the spring 13, so that the compression of the spring 13 in each water sampling bucket 2 is different. Since the pressure is greater as you go down underwater, the water pressure squeezes the float 7, causing the spring 13 to compress. Water enters the water sampling bucket 2 from the water inlet 3. As the water sampling bucket 2 is lowered, the water pressure compresses the spring 13 with the compression from small to large in sequence, and samples the water at different water layers.

[0026] A connecting rope 9 is fixedly connected between several water sampling buckets 2. A hook 10 is fixedly connected to the bottom of the connecting rope 9. A counterweight 11 is hung on the hook 10. The counterweight 11 provides sufficient weight so that the water sampler can fall normally and at the same time prevents the water sampler from tilting.

[0027] This utility model relates to a water quality stratification synchronous water sampler device, which is small in size, simple in structure, and easy to use.

[0028] The above description is only a preferred embodiment of this utility model patent and is not intended to limit this utility model patent. Any modifications, equivalent substitutions and improvements made within the spirit and principles of this utility model patent should be included within the protection scope of this utility model patent.
