Definitions

• the present invention relates to the field of devices for collecting samples of liquids, such as samples of water, in particular sea water, river water, lake water, and more in detail it relates to an improved structure of sampler for underwater inspections. Description of the prior art
• the monitoring of underwater environments, both sea environments, and lake environments, and river environments and industrial environments can be for example executed by scuba divers who plunge into the water of interest and once arrived at the area of interest use collecting devices that are operated by the scuba divers themselves for picking up manually the sample of water of interest.
• ROV underwater Remotely operated vehicles
• AVS Autonomous Underwater Vehicle
• the known remotely operated samplers have some drawbacks. Firstly, the samplers of liquid are at first empty and have therefore a predetermined starting weight. Once the sample of interest has been collected, the weight of the sampler changes with respect to the starting weight and therefore the distribution of the loads on the underwater vehicle changes. Therefore, the underwater vehicle, not more balanced, becomes difficult to be remotely operated in particular in case of small vehicles, i.e. comparable to the size of the sampler used. Therefore, in order to avoid this drawback it is necessary to use vehicles of large size. This causes a high energy consumption for supplying the vehicle and for moving the same. Furthermore, vehicles of large size have limited possibility to use because they cannot be used for inspecting ravines, small caverns, or the inside of wrecks .
• the sampler is substantially syringe-shaped, because it consists of a piston that is arranged movable in a cylinder. More in detail, the sampler is arranged in a containing case of a vehicle with the front end oriented towards the environment and the rear end arranged in the containing case same, in order not to be in communication with the outside environment.
• the sample to be examined is introduced inside the cylinder through an unidirectional valve arranged at the front end of the sampler.
• the unidirectional valve only provides a loaded spring.
• Inside the sampler is preliminarily introduced a certain amount of water that, then, is expelled through holes made in a rear cover of the sampler through which the water outflows in the hollow container body of the vehicle. Then, the water exits from the vehicle through apertures.
• the movement of the piston is guided by one, or two, springs.
• the sampler has a compensation system of the pressure that consists of a diaphragm, made of silicone rubber, and mounted at the front end of the body of the sampler at which the sample enters the cylinder. More in detail, when a sample is collected at high depth, the diaphragm expands outwards to allow a depressurization during the step of ascending in surface. Instead, when the sample is collected at low depth, i.e. near the surface, the diaphragm expands inward .
• the membrane has an elastic constant that is lower than that of the spring of the unidirectional valve.
• the sample of interest is contaminated by liquid that enters the cylinder through the unidirectional valve.
• a sampler comprising a containing chamber inside of which, before proceeding with the collecting of the sample to be examined, distilled water is introduced through an opening that, in operating conditions, is hermetically closed by a plug.
• the containing chamber remains insulated from the outside environment up to the moment of collecting the sample to be examined. More in detail, the introduction of the sample in the containing chamber is carried out through the opening of a valve that is kept in a closed position by a spring and that opens when the external pressure is higher than a predetermined value, i.e. to the achieving of a predetermined depth.
• a sampler comprising a triggering mechanism, a device for sampling the water and a pumping mechanism .
• the device for sampling the water cooperates with the triggering mechanism and comprises a removable container and a pinch mechanism.
• the removable container is arranged in the device for sampling the water and provides an inlet, an inlet tube and a collecting bag attached to the inlet tube.
• the pinch mechanism is located adjacent to the inlet tube and surrounds it and is arranged near the collecting bag. When the pinch mechanism is closed it prevents water from penetrating in the inlet tube and in the collecting bag. When it is open, the pinch mechanism allows water to enter the inlet tube and the collecting bag.
• a pumping mechanism creates a water flow for causing the collecting bag to collect water when the pinch mechanism is in the open position.
• a structure of underwater vehicle such as a remotely operated vehicle, or ROV, or an underwater autonomous vehicle, or AUV, on which at least one sampler having the same advantages is mounted.
• a piston slidingly mounted in said longitudinal recess, said piston which is adapted to divides said longitudinal recess in a first containing chamber that, in use, is always in hydraulic connection with the outside environment through at least one opening, in such a way that, in use, said first containing chamber is flooded, and in a second containing chamber equipped with at least one inlet mouth, said, or each, inlet mouth being associated with a closure member movable between a closed position of said inlet mouth and an open position of said inlet mouth;
• an actuation device arranged to selectively arrange said, or each, closure member between a closed configuration, in which said second containing chamber is hydraulically insulated from the outside environment and said first containing chamber is flooded, and a open configuration, in which said second containing chamber is in hydraulic connection with the outside environment;
• said actuation device arranged also to cause a translation said piston in said longitudinal recess from a first position, in which it is close to said, or each, inlet mouth and a second position, in which it is close to said, or each, opening, said translation of said piston producing a depression in said second chamber that causes the introduction inside of it of a predetermined volume of a liquid sample through said, or each, inlet mouth; said actuation device being then arranged to return said inlet mouth from said open configuration to said closed configuration once said piston reaches said second position;
• the actuation device can be remotely operated.
• the actuation device can be operated in predetermined conditions, for example when a predetermined depth is reached and/or when a predetermined pressure is reached and/or when a predetermined position is reached and/or at a predetermined instant and/or at a predetermined temperature.

• the actuation device can be configured to cause the movement of the inlet mouth by the closed configuration to the open configuration and to cause the piston to translate from the first to the second position, when the actuation device is crossed by a predetermined electric current generated by the power supply. For example, until the actuation device is not crossed by electric current, or is crossed by an electric current that is lower than a predetermined threshold value i*, the actuation device is adapted to keep the inlet mouth in the closed configuration and to keep the piston in the first position. Instead, when the actuation device is crossed by current, or by a current higher than the threshold value i*, it is configured to cause the movement of the inlet mouth from the closed configuration to the open configuration and to cause the piston to translate from the first to the second position.
• the actuation device is adapted to keep the inlet mouth in the closed configuration and to keep the piston in the first position until a current flows and to cause the inlet mouth to move in the open configuration and the piston to translate in the second position when it is not crossed by current, i.e. when the electric current generated by the power supply and that crosses the actuation device in the closed configuration of the inlet mouth stops to pass through the actuation device same.

Therefore, at the second position, the piston 20, remains at a predetermined distance from the stop element 12 (figure 7) . In other words, when the piston 20 is arranged in the second position, a certain amount of liquid is present in the first chamber 30 .
• the compensation of the pressure in the chamber 40 containing the liquid sample avoids, among the others, that, once in surface, at the moment of collecting the liquid sample, the container 10 does not explode owing to the difference of pressures between the inside of the chamber and the outside environment jeopardizing the whole step of collecting the liquid sample and putting also in danger the safety of the workers in case the liquid contains dangerous substances, in particular harmful, or toxic, for human beings.

• the particular technical solution to provide that the first containing chamber 30 is always hydraulically connected with the outside environment through at least one opening 31 allows, in operating conditions, to keep the chamber 30 same constantly flooded of liquid, for example of sea water in case of sea inspections. This way, it is possible to avoid the production of bubbles of air in the hollow container body 10 and to keep substantially constant the weight of the sampler 1 during all the steps of collecting of the liquid sample.
