Description

The invention relates to a means of storing petroleum products, and can be used in all areas of activity where there is a need for sheltered storage in the field of stocks of light petroleum products intended for automotive equipment.

For uninterrupted and reliable material and technical support of military and civilian equipment in remote areas, it is important to create and sheltered storage of the necessary fuel reserves, which primarily include motor gasoline and diesel fuel.

When reviewing the technical literature, a number of technical solutions related to the specified problems were identified.

A well-known tank for storing petroleum products in water, containing an open bottom housing, a pipe for supplying products, a pipe for exhausting air equipped with a float valve, a diaphragm installed in the lower part of the housing, a device for loading (inventor's certificate SU 388968, class B65D89 / 10, publ. 07/05/1973, bul. No. 29).

The disadvantages of this technical solution are:

a large volume of mixture formation of products formed when water is displaced from the reservoir during its immersion and during storage of the product in a submerged position as a result of displacements of the bottom water layers;

inability to use the reservoir on land, including in swampy areas;

inability to compensate for the thermal expansion of the product in the tank.

Known storage for oil and oil products, containing a reservoir attached to the bottom of the reservoir and located below the water level, placed in it two flexible diaphragms, combined into a block of identical reservoirs, in each of which both diaphragms are combined with each other along the periphery, a water conduit providing communication of one reservoir with another body of water (inventor's certificate SU 1220257, class B65D88 / 78, publ. 20.10.1995).

The disadvantages of this storage are:

limited possibilities for the depth of the tanks, caused by the limited height of the liquid column in the suction lines of pumps used for pumping oil and oil products;

the inability to perform operations on filling and emptying tanks with mobile technical means, which makes it difficult to use this storage facility to provide fuel for equipment in the field;

inability to use the storage facility on land, including in swampy areas.

Closest to the claimed invention is a storage located on the seabed, containing a storage section in the form of an oil and water impermeable fabric made in the form of a flexible balloon, an anchor section, a transfer section, an oleometer and an acoustic repeater for signaling an oil leak alarm, valves automatically closing in cases where the loading line, the unloading line or the storage section and the transfer section are disconnected from the storage, instruments for measuring the filling volume of the storage section, one or more pumps integrated into the storage to facilitate oil unloading (patent for invention RU 2341433, cl. B65D88 / 78, publ. 20.12.2008, bull. No. 2).

The disadvantages of this storage are:

inability to use the storage facility on land, including marshy areas;

the complexity of maintenance and replacement of pumps integrated into the storage.

The problem to be solved in the invention is to eliminate these disadvantages by implementing a technical solution that ensures the use of a storage facility for sheltered storage of fuel reserves in the field, both on water and on land, including marshy, areas of the terrain, as well as the possibility of performing operations on its filling and emptying using mobile technical means.

The technical result of the invention is to expand the scope of the storage facility for sheltered storage of fuel reserves in the field and to simplify its operation.

The problem is solved, and the technical result is achieved as a result of the fact that, according to the invention, the storage for sheltered storage of fuel supplies in the field contains at least two pipes with end walls installed in parallel in a horizontal plane relative to each other, intermediate connecting pipes connecting the end walls adjacent pipes with the possibility of ensuring a consistent gravity flow of fuel from one pipe to another, a technological gateway for placing a submersible pump in it, connected to the end wall of a pipe located at a greater depth in relation to other pipes, a filler pipe connected to a pipe located at a lower in relation to other pipes to a depth, and equipped with a flap with a float, which are installed at the end of the filler pipe placed in the inner cavity of the pipe to close the internal section of the filler pipe after the float reaches a lift height corresponding to the maximum the level of filling the pipe with fuel.

The invention is illustrated in FIG. 1-7.

The storage for the sheltered storage of fuel supplies in the field works as follows.

At the ends of each of the pipes 1, end walls 2 are rigidly connected. In the upper part of one of the ends of the pipe 1, installed at a depth that is smaller in relation to the other pipes, a hole is made (not shown) and the end of the filler pipe 4 with a shutter installed on it is fixed in it 11, to which the float is attached 12. In the lower part of the end wall 2 of the pipe 1, installed at a greater depth in relation to other pipes, a hole is made (not shown) and the end of the process gate 5, made in the form of a pipe, with a diameter allowing freely fit into its internal cavity a submersible pump 8 with a hose 9 attached to it and an electric wire (not shown) placed in a protective sheath 10. The total number of pipes 1 is determined based on the volume of the internal cavity of each of them and the required volume of fuel to be contained in storage.

The installation of pipes 1 is performed starting with pipe 1, which is placed at a greater depth in relation to other pipes. In this case, this pipe is laid with a slope towards the end wall 2 with a technological gateway 5 attached to it, and a hole (not shown) is made in the upper part of the opposite end wall 2 and the end of the intermediate connecting pipe 3 is fixed in it, the second end of which is attached to the lower part of the end wall 2 of the adjacent pipe 1, installed with a slope towards this end wall 2 parallel to the first pipe 1. In the upper part of the opposite end wall 2 of the second pipe 1, the end of the next intermediate connecting pipe 3 is also fixed and in the previously given sequence, the connection with the end wall 2 of the next pipe 1. As a result, provide the possibility of sequential gravity overflow of fuel from one pipe 1 to another when filling and emptying the storage for sheltered storage of fuel reserves in the field.

After installing the pipe 1, which is at a shallower depth in relation to other pipes, the free ends of the filler pipe 4 and the technological gateway 5 are placed in the technological well 6 and plugs 7 are installed on them. The technological well 6 and plugs 7 are made with the possibility of preventing unauthorized access by unauthorized persons to the ends of the filler pipe 4 and the process sluice 5. A submersible pump 8 is also placed in the process well 6 with a hose 9 connected to it and an electric wire (not shown) placed in a protective shell 10.

To fill pipes 1 with fuel, open the process well 6, remove the plugs 7 from the ends of the filler pipe 4 and the process lock 5, connect a mobile technical device with fuel (not shown) to the filler pipe 4 and pump fuel from it into the pipe 1, which is on the smaller in relation to other pipes depth. After filling this pipe 1, the fuel through the intermediate connecting pipes 3 through the end walls 2 sequentially enters the inner cavity of each of the subsequent pipes 1. After the fuel level comes into contact with the float 12, the shutter 11 connected to it gradually overlaps the inner section of the end of the filler pipe 4, as a result of which stops the flow of fuel into the pipe 1, which is at a lower depth in relation to other pipes. The operation of the mobile technical means with fuel (not shown) is stopped, it is disconnected from the filler pipe 4, plugs 7 are installed at the ends of the filler pipe 4 and the technological gateway 5, and the technological well 6 is closed.

To dispense fuel from the storage, a technological well 6 is opened, the plugs 7 are removed from the ends of the filler pipe 4 and the technological sluice 5. A submersible pump 8 is introduced into the internal cavity of the process sluice 5 and, holding it with a hose 9 with a protective shell 10 attached to it, in which is placed an electric wire (not shown) to supply electricity to the submersible pump 8. The free end of the hose 9 is placed in a container installed on a mobile technical device (not shown), an electric wire (not shown) is connected to its power supply system and the submersible pump 8 is turned on. After filling the container installed on the mobile technical device (not shown) with the required amount of fuel, the submersible pump 8 is turned off, it is taken out of the technological gateway 5 by means of a hose 9 with a protective shell 10 attached to it, an electric wire is disconnected from the power supply system of the technical device (not shown) submersible pump 8, install t plugs 7 at the ends of the filler pipe 4 and the process lock 5 and close the process well 6.

The storage, according to the invention, this storage can be used in any areas of the terrain, both underwater and underground, including in swamps, and due to the absence of large-sized aboveground parts in its structure, it can provide a hidden location of the storage on the ground, with protection from unauthorized access of unauthorized persons to structural elements.

Thus, as a result of the implementation of the proposed technical solution, it is possible to expand the scope of application of the storage facility for sheltered storage of fuel reserves in the field and simplify its operation by ensuring the possibility of its construction both on water and on land, including swampy areas, and also perform operations for filling and emptying it using mobile technical means.
