Description

Field of technology

The device according to the utility model refers to the field of devices for taking water samples from natural and artificial water basins. It will find application as part of the equipment of research ships, robotic systems for research of water bodies and others.

BACKGROUND OF THE INVENTION

A device for taking water samples is known, comprising a container, which is a tube provided with caps at both ends, which are equipped with closing springs. Each cap is fitted with a part made of ferromagnetic material, which in the open position of the cap comes into contact with an electromagnet mounted on the tube. Attached to the container is a fastener connected by a supporting steel rope, which is combined with an electrical power cable connected to the two electromagnets. The steel rope and the electric cable are passed through a support roller and are wound on an automated spool, which can be remotely controlled. The support pulley and reel are mounted on board the vessel. In most embodiments, the container of the device is plastic to avoid contamination of the samples.

The described device works by lowering the container into the water with open caps by means of the spool, the support roller and the bearing steel rope. The open position of the caps is maintained under the influence of the two electromagnets that counteract the closing springs. Upon reaching the required depth from which the sample will be taken, the power supply via the cable to the two electromagnets is interrupted, whereby the caps close automatically under the influence of the springs. The closed container is pulled back to the vessel and the sample is ready for examination.

If the open container passes through contaminated water as it moves downwards, deposits may form on the inner surfaces of the pipe and caps. The described device does not provide a mechanism for cleaning these surfaces before sampling. The lack of such a possibility may in some cases lead to the taking of a contaminated sample, which may cause incorrect test results.

Technical essence of the utility model

The purpose of the utility model is to create a device for taking water samples, which allows the container to pass through contaminated water, without leading to the possibility of spoiling the sample.

The object is achieved by means of a water sampling device comprising a detachable container in which one or more water vessels are arranged, connected by pipes (hoses) to suction pumps. The latter are connected to the aquatic environment by means of suction pipes located at the top of the container. The water tanks are equipped with one-way exhaust valves, which are connected to the water environment through exhaust pipes located in the lower part of the container. Attached to the container is a fastener connected by a supporting steel rope, which is combined with an electric power cable connected to the suction pumps. The steel rope and the electric cable are passed through a support roller and are wound on an automated spool, which can be remotely controlled and equipped with a sensor for measuring the depth of immersion (the length of the developed rope). The support pulley and the automated reel are mounted on board a vessel.

An embodiment of the device is possible, in which the pumps are powered by electric batteries mounted in the container, and no electric power cable is provided. Suction pumps are equipped with electronic units for wireless control.

The water tanks of the described device have contact with the water environment only when the suction pumps are activated. If the container passes through contaminated water before sampling, the water containers will not become contaminated. This guarantees the purity of the water samples and is a major factor in achieving correct test results.

Explanation of the attached figure

Figure 1 shows a drawing of the water sampling device according to the utility model.

Exemplary implementation of the utility model

An exemplary embodiment of the water sampling device is shown in Figure 1. The device comprises a metal detachable container 6 in which are located two water containers 1 connected by hoses to two suction pumps 2. The pumps 2 are connected to the water environment by means of suction pipes 3 located in the upper part of the container 6. The water tanks 1 are provided with one-way exhaust valves 5, which are connected to the water environment through exhaust pipes 4 located in the lower part of the container 6. A hook is attached to the metal container 6. 7, connected to a supporting steel rope 8, which is combined with an electric power cable connected to the suction pumps 2. The steel rope 8 and the electric cable are passed through a support roller 9 and wound on an automated spool 10. The support roller 9 and the automated spool 10 are mounted on board a vessel.

Using the utility model

The device according to the utility model is used as the metal container 6 is lowered into the water by means of the spool 10, the support roller 9 and the steel rope 8. Upon reaching the required depth from which the sample will be taken, power is supplied to the pumps 2. begin to suck water through the suction pipes 3 and fill the vessels 1. When a certain pressure is reached in the vessels 1, the exhaust valves 5 open and release part of the water to the water environment through the exhaust pipes 4. When it is judged that the amount of water in the vessels 1 is sufficient, the power supply to the pumps 2 is interrupted. The container 6 is pulled back on board the vessel and the sample is ready for examination.
