Description

The invention relates to the fishing industry and can be used for transporting live cold-water crustaceans. In particular, this system is used for transporting snow crab opilio or king crab.

Various versions of such devices are known from the prior art, for example, from the source RU 2550426 C1, published on May 10, 2015, a method of transporting crabs is known, which includes reducing their vital activity and placing them in a transport container while maintaining a low temperature during transportation through the use of cold sources that placed in a container. According to the known method, before transportation, the crab is placed in a state of anabiosis and transported in this state, while the isothermal container is sealed and during its transportation a temperature regime is maintained in it, which prevents the crab from emerging from the state of anabiosis, while the crabs are placed in the container in a state of adducting their paws to the body, in at least two layers, with the lower ones placed on a lining of porous elastic material moistened with sea water, after which each crab is closed from above and pressed with a covering of a similar material, separating them from each other. As a source of cold, small-sized cold accumulators are used, which are poured into the volume of the container not occupied by crabs and coating; in addition, after filling the container, its joints are sealed, for example, with adhesive gas-tight tape, then the containers, preferably not one at a time, are hermetically sealed in a flexible thermal insulating material. thermofol material, after which it is transported to the consumer.

However, this method allows for the transfer of an insufficient number of crabs at the same time, and also ensures the transportation of crab over short distances.

Also known from the prior art is CN 105145440 A, published on 12/16/2015, which discloses a device that contains multiple rows of aquaculture water tanks, an oxygenation system and a water purification machine. Aquaculture water tanks are made of clear glass using bonding method. Each row of an aquaculture water tank is formed by connecting a plurality of cells in series with open tops. Each cell is equipped with a small hole permeable to water. The aeration system supplies oxygen to the entire device and contains an aerator, a main air supply pipe, a number of small air supply pipes and a number of gas stones. The aerator is connected to the main air supply pipeline. The main air supply pipeline is equipped with small air supply tubes. Each small air supply pipe is equipped with one gas stone. Each cell is equipped with one small tube for supplying air and one gas stone. The water purification machine is used to produce deionized water and is the water source for the entire device.

This source of information was taken as the closest analogue to the claimed invention.

However, the disadvantage of the closest analogue, as well as the entire level of technology, is the inability to transport live crab over long distances in sufficiently large quantities.

Thus, the objective of the claimed invention is to eliminate the disadvantages of the prior art.

The technical result to which the claimed invention is aimed is to increase the distance over which live crab can be transported in a 40-foot container. An additional technical result is an increase in the amount of crab transported simultaneously in a 40-foot container and the achievement of almost 90-100% survival rate of the crab during transportation.

The claimed technical result is fully achieved by the set of features stated in the independent claim of the formula.

The system for ensuring the vital activity of the crab during transportation contains a forty-foot shipping container equipped with a refrigeration system, in which identical cubic containers with temperature sensors are installed in two rows of eight pieces and in each row under one technical block. Each container contains side walls, a bottom, an upper wall and a neck with a lid; on the upper wall of each container there are two ventilation pipes mounted on the container using a coupling and an outlet. A discharge pipe and a suction pipe are attached to one of the side walls of each container using an adapter, ensuring constant circulation of water between the containers connected in series in one row and the technical unit. Each technical unit contains a metal frame and a self-priming pump with a pre-filter, an oil-free piston air compressor, shut-off valves for transitions, a manifold for injection connections and a control panel mounted on it.

The discharge pipe consists of an angle, a coupling, a camlock, an adhesive fitting, an adapter angle, a pipe, pipe sections, a reinforced hose and a clamp.

The suction pipe is designed to draw water from the container into the technical unit and consists of an angle, an outlet from the container, a camlock and a glass with holes with a diameter of 10 mm, installed from the inside of the container.

The supplied water in the container from the pump passes through a sleeve with a temperature sensor of the passing water.

The claimed invention is further illustrated in more detail by drawings, in which:

In fig. 1 (a, b, c) shows a Eurocube type container for transporting crab in the claimed system.

In fig. 2 (a, b, c) shows the technical block of the claimed system.

A standard forty-foot container fits 9 modules along and 2 modules across as conveniently and compactly as possible, and therefore the claimed system for transporting live crab in a forty-foot container consists of two lines installed side by side, each of which consists of eight cubic lines installed in a row containers and one technical unit, occupying the space of one module in size.

The claimed system consists of two lines, each of which consists of eight identical containers (19) of the Eurocube type, with a volume of 1 m ³ , each of which contains side walls, a bottom, a top wall and a neck with a lid (18) with a diameter of 700 mm, and technical block (see Fig. 2a, 2b, 2c).

On the upper wall of each container (19) there are two ventilation pipes (1), secured to the container (19) using a coupling (2) and an outlet (3).

A discharge pipe and a suction pipe are attached to one of the side walls of each container (19) using an adapter (9), ensuring constant circulation of water between the containers and the technical unit.

The discharge pipe is intended for the flow of purified water into the container (19) from the technical unit and consists of an angle (4), a coupling (5), a camlock (6), an adhesive fitting (11), an adapter angle (10), a pipe (15), sections of pipes (16), reinforced hose (17) and a clamp (12) connecting the adapter angle (10) to the pipe (15). The reinforced hose (17) has holes along its length with a diameter of 6 mm at a distance of 100 mm from each other.

The suction pipe is designed to draw water from the tank (19) into the technical unit and consists of an angle (7), an outlet (13) from the tank, a camlock (8) and a glass (14) with holes with a diameter of 10 mm, installed from the inside of the tank (19) .

The tanks are also equipped with water temperature sensors, which are connected to the panel (38).

Each line contains its own technical unit, which is responsible for the normal operation of each line tank during the transportation of live crab.

Each technical unit contains a metal frame and a self-priming pump (21) with a pre-filter, an oil-free piston air compressor (22), shut-off valves for transitions, a manifold for injection connections and a control panel (38) mounted on it. The grounding wire must be connected to the metal frame through point (55).

The pump (21) creates pressure in the discharge manifold through the camlock (28), then, using a reinforced hose (not shown in the figure), it is connected in series to all eight tanks of the line. The compressor (22) supplies air at excess pressure to the discharge manifold, from which air is supplied to the line tanks by means of air hoses through quick-release connections with camlocks.

In addition, the supplied water in the container from the pump (21) passes through a sleeve (54) with a temperature sensor of the passing water.

If the temperature is not optimal for transporting live crab, it is cooled using the refrigeration unit of the semi-trailer.

After assembling a line of eight tanks and a technological block, connecting the corresponding reinforced hoses on the discharge line and suction line, all tanks are filled through the technical block system to the outlet level (sea water for the system comes from a natural source (in a particular case - from the Kola Bay of the Barents Sea ), undergoes filtration, disinfection and cooling). The pump (21) is started to pump water through the system of containers; after filling the technological diagram, water is added to the level of the pipe (13). The compressor (22) is turned on, the unit enters operating mode with constant monitoring of the stability of circulation and air supply. Live crab is loaded through the necks. Excess water is forced out through the drainage ball valve (8). The faucet has a standard device; the ball has a round hole through which the working medium moves. The seat and plug are sealed with synthetic rubber or fluoroplastic. There is a handle to turn the rod in the desired direction.

The system is powered by an autonomous diesel generator installed on the semi-trailer (not shown in the figure).

During transportation, the temperature in the container, the temperature of the water in the containers and the water flow (system operation) are monitored using sensors. Data is displayed online through a mobile application.

Thus, the above design of the crab transportation system ensures the achievement of the stated technical result, namely, providing the possibility of increasing the distance over which live crab can be transported by road with an increase in the amount of transported crab due to the fact that the claimed system ensures continuous circulation of sea water necessary temperature (from +1 to +3 degrees Celsius) ensuring continuous air supply.

When using the declared system, up to 3.7 tons of snow crab opilio, or up to 4 tons of king crab can be transported at a time during one transportation.
