technical field

The utility model belongs to the field of water quality sampling instruments, in particular to a piston-type deep-layer water sampler, which is used for collecting and analyzing bottom water samples.

Background technique

Water body sampling is an important part of water environment protection and water environment scientific research. The collection of water samples at different depths, especially deep water samples, has become the premise and basis for carrying out various water resources research work.

At present, a variety of commercial deep water samplers (or devices) have been developed, which can collect deep water samples with different requirements. Deep water samplers are mainly divided into two categories, one of which is mostly designed for marine scientific research work, which requires special ships to provide power and lifting equipment, and has the characteristics of complex structure and difficult operation; the other is suitable for rivers, Inland water bodies such as lakes and reservoirs are easy to operate, but when this type of sampler samples deep water, the operation steps are too complicated, which will undoubtedly increase the difficulty of the sampling personnel's work and affect the sampling efficiency.

Utility model content

The purpose of the utility model is to overcome the deficiencies of the prior art, and provide a piston-type deep water sampling device with simple operation, low material cost and wide application range.

The technical scheme that the utility model realizes purpose is as follows:

A piston type deep water sampling device is characterized in that it includes a base, a hollow cylindrical cylinder, a circular water baffle in the cylinder and a lifting rope, a counterweight is fixed inside the cylindrical base, and a counterweight is fixed inside the cylindrical base. The upper surface of the base is coaxially fixed with a hollow cylindrical cylinder. A circular water inlet hole is left in the center of the top of the cylinder. A circular water baffle that can slide up and down along the axis of the cylinder is installed in the cylinder. The upper surface of the water baffle is Fixed handle in the middle. A handle is fixed on both sides of the top of the cylinder body, and a handle rope is fixed on the top of the handle.

Moreover, the water baffle in the sampling cylinder is circular, and the diameter of the circular water baffle needs to be between the diameter of the circular water inlet hole at the top of the sampling cylinder and the diameter of the sampling cylinder.

The beneficial effects of the utility model are:

1. In the water harvester provided by the utility model, a counterweight is fixed inside the cylindrical base, and a hollow cylindrical cylinder is coaxially fixed on the upper surface of the cylindrical base, and a circular water inlet hole is left in the center of the top of the cylinder. , which can ensure that when the water collector is connected to the water body, the water body will quickly enter the sampler, improving the sampling efficiency.

2. The water harvester provided by the utility model is fixed with a base at the bottom of the cylindrical cylinder, and a counterweight is installed in the base. The weight is installed in the base, not only is not easy to fall off, but also is protected by the cylinder material and is not easy to grow. rust.

3. The cylinder body of the water harvester provided by the utility model is equipped with a circular water baffle that can slide up and down along the axis of the cylinder. Move down, close or open the water inlet hole at the top of the sampler at the same time, you can easily collect water samples at the bottom, and the operation is very convenient.

Detailed ways

The utility model will be further described in detail below in conjunction with the accompanying drawings and through specific embodiments. The following embodiments are only descriptive, not restrictive, and cannot limit the protection scope of the utility model.

A piston-type deep water sampling device, comprising a base 6, a hollow cylindrical cylinder 5, a circular water retaining plate 4 in the cylinder and a lifting rope, a counterweight 7 is fixed inside the cylindrical base, and a counterweight 7 is mounted on the cylindrical base The upper surface of the base is coaxially fixed with a hollow cylindrical cylinder. A circular water inlet hole is left in the center of the top of the cylinder. A circular water baffle that can slide up and down along the axis of the cylinder is installed in the cylinder. The upper surface of the water baffle is The central part is fixed with a lifting rope 2. A handle 3 is fixed on both sides of the cylinder top, and a handle rope 1 is fixed on the top of the handle. The water baffle in the sampling cylinder is circular, and the diameter of the circular water baffle needs to be between the diameter of the circular water inlet hole at the top of the sampling cylinder and the diameter of the sampling cylinder.

The working principle of the water collector is as follows:

The water sampler is used to collect water samples for analysis in the predetermined water layer. Use the lifting rope to pull the water baffle to move up and down along the axis of the sampling cylinder, and at the same time close or open the water inlet hole on the top of the sampler. When the upper surface of the water baffle is lifted When the rope is loosened, the water retaining plate moves downward in the sampling cylinder, and the water inlet hole at the top of the sampling cylinder communicates with the outside world; when the lifting rope on the water retaining plate is tightened, the water inlet hole at the top of the sampling cylinder is blocked. The water plate is blocked, and then the whole sampling cylinder is sealed.

The working process of the water collector is as follows:

When the water collector is put into the water, the cylinder sinks under the action of the weight in the base. When the cylinder reaches the predetermined depth, fix the rope at the top of the handle to keep the position of the sampling cylinder, and release the water baffle to lift it up. The water baffle moves downward in the sampling cylinder, the water inlet hole is opened, and the water body enters the sampling cylinder. After the sampling is completed, the water baffle is pulled up by the lifting rope, and the water baffle is pulled up by the lifting rope, and then the water enters The hole is closed, loosen the lifting rope at the top of the handle, and continue to pull up the lifting rope on the upper surface of the water deflector. The whole cylinder is pulled up in the water by the water deflector until it is taken out. After the sampling is completed, the device can be tilted when taking water. The water is taken out.
