(RU 2617244). The disadvantages of such a gas filling unit include the technological complexity of its execution, the use only for identical gas cylinders, the impossibility of quick installation on agricultural machinery.

Gas monoblocks made of lightweight steel cylinders are known, intended for supplying large consumers with technical and pure gases (oxygen, ammonia, propane, acetylene, nitrogen, argon, hydrogen, helium, carbon dioxide, methane, LPG, etc.), as well as receivers and reserve gas sources for continuous technological processes (see, for example, (https://mvif.ru/monobloki/, or the site https://mvif.ru/ballonnyj-akkumulyator-gaza-bag-iz-stalnyh-ballonov-dlya-komprimirovannogo-prirodnogo-gaza-kpg). However, they are difficult to use for horizontal placement on agricultural machinery, there are no systems of side fastenings and clamps for articulating monoblocks, and only single-sized monoblocks are used for articulating with each other.

The closest technical solution to the proposed invention is a replaceable cassette for tanks filled with gas motor fuel (see Patent for Invention RU 2704593, IPC F17C 13/08; B60P 7/13; B60S 5/02; B60K 15/07; B60P 1/54), comprising a supporting frame, at least one vessel for gas motor fuel fixed in it with gas connection fittings and a quick-release nipple, a lifting device and a locking device, wherein the cassette, standing vertically, fixed in the transport position, has flat-oval shaped vertically supporting journals mounted coaxially on the sides with an outward offset from the center of gravity on one of the sides of the frame, transport hooks are located below the journals on at least one side of the frame, and above the center of gravity along the line of action of the force of the center of gravity on the sides of the frame parallel to the axis of the trunnions, the axes of the load-bearing hinges are fixed, to which the frame of the load-bearing beam traction with the load-gripping device and the device for fixing the beam in the vertical position are connected, embracing the frame on both sides, dampers are installed in the upper part of the cassette on the outer side opposite to the trunnions along the edges of the frame, near which there are additional hooks on the frame, the cassette is transported in a vertical position by fixing it by the trunnions in special brackets with a flat-oval vertical socket installed on board the vehicle on one side, and by transport hooks on the other, and the cassette can be laid down and fixed on board the consumer of the gas-mechanical transport vehicle either vertically in brackets similar to those on the vehicle, or in a horizontal position, turned at an angle of up to 90 degrees from the vertical, at least in one tier in working brackets with a round socket for the trunnions on one side, and on the other by resting the dampers of the frame in special supports with fixation by additional hooks on the frame, while in the horizontal section of the vertically standing cassette the arrangement of the vessels, if there are several of them, can have a quadrangular, round, oval, triangular or their variant combination shape, and the gas connecting fittings can have two quick-release nipples - one for filling and the other for dispensing the gas-metal fuel. The replaceable cassette according to item 1, characterized in that the cassette is laid directly behind the axes of the load-bearing hinges, and the crossbar is made quick-release, adjustable for different cassette widths. The replaceable cassette according to item 1, characterized in that, regardless of the number of cylinders in the cassette and the option of loading them, one part of at least a single load-bearing vertical hinge is secured to one of the outer sides of the frame, the second mating part of which is installed on the LMT consumers, on at least one of the opposite sides, the frame is provided with an additional support and a device for additional fixation of the cassette, and the raising and lowering of the cassette is carried out using a load-gripping device vertically in a direction parallel to the axis of the vertical hinge, while the fastening of the cassette on the vehicle can be either unified with the LMT consumer or independent of it. The replaceable cassette according to item 3, characterized in that, on the outer side of the frame, one part of at least a single horizontal hinge is secured, the mating part of which is installed on the LMT consumer. The replaceable cassette according to any of paragraphs. 1-4, characterized in that in the variant design the vessels are packed in a frame through damping devices or the cassette is equipped with external damping devices.

The disadvantage of this device is the high labor intensity of manufacturing the structure, the impossibility of adjusting the cassette depending on the length of the cylinders, and the lack of systems to prevent the occurrence of static charges.

Disclosure of invention

The technical result that can be achieved with the help of the proposed invention is reduced to fast refueling of mobile and stationary consumers of compressed natural gas (CNG) and gas motor fuel (GMF), with refueling without a booster compressor, ease of manufacture, increased reliability of fixation, reduced time and labor intensity of assembly and disassembly of replaceable cassettes among themselves and on the end consumer, for example, a tractor, while ensuring optimal fixation and distribution of gas equipment, unification of the use of gas cylinders of different volumes and sizes, prevention of the occurrence of static charges.

The technical result is achieved using a replaceable cassette for tanks filled with gas motor fuel, containing a frame, tank (cylinder) fixation devices and a conductive gasket. In this case, the frame is made with the possibility of sliding and sliding due to the movement along its axis of guides inserted into each other with a small gap. In this case, technological openings are provided for rigid fixation of the guides using special bolts upon reaching the desired technological length of the tank (cylinder), as well as fastening to the consumer device (mobile and stationary). Technological openings in the frame of the replaceable cassette for tanks allow rigidly connecting gas cylinders of different lengths, for example, for optimal weight distribution, loading on a mobile device of gas equipment (along the axis of the wheels, front and rear hitch), as well as for rational refueling, depending on the daily need for gas motor fuel, ensuring complete autonomy of the consumed unit without breaks for refueling. In the proposed invention, in order to prevent the occurrence of static charges that are particularly dangerous for gas motor fuel due to a possible explosion due to friction forces arising during vibration due to the movement of replaceable cassettes to the consumer and their operation on mobile devices, it is proposed to use an electrically conductive gasket (rubber) between the container (cylinder) and the device for fixing the container (cylinder). In this case, the gap in the working state of the replaceable cassette between the container (cylinder), the electrically conductive gasket (rubber) and the bracket fixing it is not provided. In this case, the device for fixing the container (cylinder) is made with the possibility of its movement and fixation in the standard technological openings of the frame using special bolts.
