Description

The invention relates to means of storage, transportation and mechanized transshipment of liquids, mainly to folding reservoirs for liquid hydrocarbons, and can be used in all areas of the economy, where there is a need for loading, transportation and discharge of transported liquids without the use of special vehicles and pumping facilities.

In the practice of transporting liquids, it becomes necessary to carry out loading and unloading and transport operations in the absence of the possibility of using special tankers (gas tankers), for example, when collecting emergency spills of liquid hydrocarbons in trunk pipelines. In this case, during transportation, it is necessary to prevent the displacement of the center of gravity of the tank under the influence of centrifugal forces, as a result of which the vehicle may tip over. For this, a rational combination of rigidity and variability of the geometry of the tank body is required, in which the body geometry is maintained under the influence of centrifugal forces and is changed to create a vacuum or pressure in the internal cavity of the tank during filling or emptying.

When reviewing the technical literature, technical solutions are identified that relate to tanks for transporting liquids with varying body geometry.

A well-known tank for liquids (see SU 1093632, class B65D 90/28, B60K 15/02, publ. 05.23.1984), comprising a housing with a corrugated shell attached to the bottom and cover with the possibility of vertical movement relative to the guides, lifting a device attached to the lid of the load in the form of a plate connected to a lifting device, air-filling, intake and drain taps. The disadvantages of this device are:

- insufficient rigidity of the corrugated shell design and the inability to fix the position of the plate attached to the lid, which during transportation of the transported liquid does not prevent the displacement of the center of gravity of the tank under the influence of centrifugal forces;

- the exclusion of the possibility of compact transportation of an empty tank, since the dimensions of its hull are unchangeable, as a result of which the vehicle loaded with an empty tank cannot be used for passing transportation of non-specific goods, which reduces the efficiency of its operation.

The closest technical solution to the invention is a reservoir for liquids (see RU 1093632, class B65D 90/28, publ. 01/27/1998), containing a rigid body, a cover with technological nozzles, a bottom with a drain pipe, fasteners, rigidly mounted on the lid of the tank, and power cylinders with a source of the working medium, support rollers, two pairs of sliders installed in pairs on opposite sides of the body and made in the form of plates symmetrical with respect to one another with vertical and inclined slots, in each of which the support roller of an individual fixing device is freely placed, nozzles rigidly fixed on the ends of the piston and the housing of each power cylinder, flexible rods, the blocks of which are mounted on the nozzles of the power cylinders, pairwise symmetrical figured housing modules connected to the cover, bottom and between them with the possibility of the formation of longitudinal corrugations, elastic pads.

The disadvantages of this tank are:

- the complexity of the design, which consists in the use of a large number of heterogeneous constituent elements, which leads to a decrease in the reliability of the tank during its operation in difficult conditions (as a result of freezing of rubbing elements at low ambient temperatures, ingress of foreign objects, dirt, etc. when operating tanks in the field);

- the difficulty of ensuring the tightness of the connection of the elastic plates with the side, end and corner modules of the tank body.

The objective of the invention is to develop a technical solution that ensures the elimination of these disadvantages.

The technical result of the claimed invention is to increase the reliability of the tank with the required variability of the geometry of its body and tightness.

The problem is solved, and the technical result is achieved as a result of the fact that the tank for transporting liquids with varying body geometry, comprising a roof, a bottom, pairwise movably connected side and end folding modules, a removable neck, two power cylinders, a discharge and filling pipe, and discharge hoses, according to the invention, is provided with an elastic sheath placed in an internal cavity bounded by a roof, a bottom and folding modules, and attached to them by means of fasteners tov, a supercharger of a compressed medium with a drive, while:

- each power cylinder with its supporting part is movably attached to the lower part of the support located under the long side of the bottom in the middle of it, and the rod of the power cylinder is movably attached to the center of the lower side folding module;

- the length of the bottom is equal to the sum of the length of the roof and the width of the folding module, and its width is equal to the sum of the width of the roof and the width of the folding module;

- side and end folding modules are made with the possibility of folding in the direction of a vertical plane passing along the sides of the tank bottom;

- the internal cavity of the compressed air compressor located on the side opposite to the internal cavity with the rod located in it is connected via the injection hoses to the internal cavity of each of the power cylinders located on the side of the rod located in it, and the internal cavity of the compressed air compressor located on the side the rod located in it is connected by means of discharge hoses to the internal cavity of each of the power cylinders located on the side opposite to the internal cavity with stock in her stock.

The tank for transporting liquids with varying body geometry works as follows.

In the internal cavity bounded by the roof 1, the bottom 2, the upper side folding modules 3, the lower side folding modules 4, the upper end folding modules 5 and the lower end folding modules 6, place an elastic shell 8 and fix it with fasteners 11. Support part each power cylinder 13 is movably attached to the lower part of the support 7, which is placed under the long side of the bottom 2 in the middle of it, and the rod of the power cylinder 13 is movably attached to the center of the lower side folding module 4. In addition, the supports 7 are fixed at the other four angles of the bottom 2.

To fill the tank, the discharge pipe 12 through a flexible sleeve (not shown) pre-connected to it is connected to a container (not shown) with liquid intended for transportation, a shut-off element (not shown) is opened on the discharge pipe 12, and it is turned on through the drive the rod 16 of the compressed air compressor 14. At the same time, the process pipe 10 connected to the removable neck 9 is closed. The pressure of the compressed medium generated from the internal cavity of the compressed air compressor 14 located on the side of the her rod 15, through the discharge hose 17 is transmitted into the inner cavity of each of the power cylinders 13 located on the side opposite to the inner cavity with the rod placed in it. The rod of each of the power cylinders 13, movably attached to the center of the lower side folding module 4, moves it around the axis of the movable connection of the lower side folding module 4 with the bottom 2. Through the movable connection, the lower side folding module 4 moves the upper side folding module 3 around the axis of the movable connection the upper lateral folding module 3 with the roof 1 and raises the roof 1. The rise of the roof 1 through the movable joints leads to the movement of the upper end folding modules 5 around the axes of these joints, as well as the lower end folding modules 6 around the axes of their joints with the bottom 2. In this case, the internal cavity of the elastic shell 8 expands, and under the influence of the generated vacuum, the liquid from the connected tank (not shown) through a flexible sleeve (not shown) and a discharge pipe 12 enters the internal cavity of the elastic shell 8. After completing the filling of the internal cavity of the elastic shell 8, the process pipe 10, connected to the removable neck 9, is opened through the compressor supercharger 14 yat rods of the power cylinders 13 in the opposite direction of movement, remove air from the inner cavity of the elastic shell 8, turn off the actuator of the rod 16, close the process pipe 10, close the shut-off element (not shown) on the discharge pipe 12 and disconnect the flexible sleeve (not shown) connected to a container (not shown) with liquid.

To empty the tank, the discharge pipe 12 through a flexible sleeve (not shown) pre-connected to it is connected to a container (not shown), a shut-off element (not shown) is opened on the discharge pipe 12, the compressed air compressor 14 is turned on via the rod drive 16 The pressure of the compressed medium created in this way from the internal cavity of the compressor supercharger 14, located on the side opposite to the internal cavity with the rod 15 located in it, is transmitted through the injection hose 17 to the internal cavity of each of the forces O cylinder 13 located on the side receiving the stem. The rod of each of the power cylinders 13, movably attached to the center of the lower side folding module 4. The rod of each of the power cylinders 13, movably attached to the center of the lower side folding module 4, moves it and the upper side folding module 3 attached to it, as a result of which lowering the roof 1. Lowering the roof 1 through movable joints leads to the movement of the upper end folding modules 5 and the lower end folding modules 6. In this case, the elastic shell 8 is squeezed, and under the influence m is created when the fluid pressure from the interior of the elastic membrane 8 via a flexible hose (not shown) and a drain and water inlet pipe 12 enters into the connected reservoir (not shown). After the emptying of the inner cavity of the elastic shell 8 is completed, the actuator of the rod 16 is turned off, the locking element (not shown) is closed on the discharge pipe 12 and the flexible sleeve (not shown) connected to the container (not shown) is disconnected.

Filling the tank with the help of extraneous pumping means is carried out in the same sequence, but in this case, to ensure the flow of fluid into the internal cavity of the elastic shell 8, the rod drive 16 is turned off.

The emptying of the tank using an extraneous pumping means or by gravity is carried out in the same sequence, but the rod actuator 16 is turned off.

Thus, the implementation of the proposed technical solution allows to increase the reliability of the tank, simplifying the design with the required variability of the geometry of its body and tightness.
