Description

The invention relates to a reservoir made of plastic and can be used for storage and accumulation of water and other liquids in an underground or ground location.

Known concrete underground tanks, such as "Septic tank" according to the patent for the invention RU 2055816 C1, publ. 03/10/1996. The disadvantages of such tanks include the fact that their installation and assembly is possible only on site, subject to the use of lifting mechanisms, while additional waterproofing of structures is required.

Known "Collection tank (options)" according to the utility model patent RU 117406 U1, publ. 06/27/2012, intended for storage of liquid or bulk food and non-food products. However, the disadvantages of the device include the fact that its design is complex, material-intensive, consists of a large number of elements that need to be sealed together, the high complexity of manufacturing elements and assembly, the need to test for leaks after assembly is completed, and the inability to use for underground location.

Known are "Steel horizontal tanks for petroleum products" according to GOST 17032-2010, which can also be used to store technical water and non-aggressive products at above-ground and underground locations, but they are complex, metal-intensive and labor-intensive to manufacture, have a significant mass, require protection against corrosion.

Known "Reservoir" according to the patent for the invention RU 2261308 C2, publ. 09/27/2007 for the storage of water or sewage or for use as a septic tank, intended for use buried in the ground and made of plastic, its inner surface in the form of a torus has essentially the same shape as the surface formed by a closed curve, which rotates about an axis at the same level so that the height of the tank in use is less than the height of a spherical tank of the same volume. The disadvantage of such a tank is that its dimensions and, therefore, the capacity is limited by the width of the vehicle body (2.4 m) for transportation. The capacity can be slightly increased only by replacing the generatrix in the form of a circle with another closed curve (oval, rectangle) with an increase in the height of the tank, while maintaining the necessary safety margin, an increase in wall thickness is also required.

Known tank for storing water (patent RU142440U, published: 06/27/2014), sewage and other liquids or for use as a septic tank, and the tank is non-pressure, intended for use submerged in the ground or for ground use, characterized in that the external and the inner surfaces of the tank have essentially the same shapes as the surfaces formed by coaxial circles elongated along the trajectory of a flat symmetrical polygon with at least six faces so that an elongated hollow O-shaped figure with a slit-like hole between the surfaces is obtained. In the analogue, it is possible to create a one-piece plastic non-pressure tank for use submerged in the ground, which provides a large capacity at a comparable height.

The closest analogue is a horizontal container for storing liquid (patent RU151535U, published: 04/10/2015), containing a hollow cylindrical body with a neck, made as a single unit with the formation of a monolithic structure, consisting of a shell, end sides that are integral with it, a neck cover that differs the fact that the cylindrical body is provided with support formations made with the body as a whole, some of which are symmetrically placed in the lower part of the cylindrical body, and the other part is symmetrically placed in the upper and lower parts of the end sidewalls, and the neck of the body is placed on the support formation of the upper surface body with an offset to one of the end sidewalls.

The technical problem of the prototype and other known solutions is the limited volume of the container, the impossibility of increasing its volume.

The objective of the invention is to eliminate these disadvantages.

EFFECT: technical result is a sealed container, the volume of which can be increased by increasing intermediate modules of the same type.

The specified technical result is achieved due to the fact that a modular tank is claimed, made of a polymeric material, containing a hollow body with a neck, parts of which are made as a single unit, consisting of a shell, end sides connected to it, a neck cover, and the neck of the body is placed on the support formation of the upper surface of the housing, characterized in that the sidewalls and the shell are made as separate parts connected by the ends, where the sidewalls are made with the possibility of connection with each other and with the shell, and the shell is made with the possibility of connection with modules of the same type, and the shell and those parts of the sidewalls , which are connected to it, are made of a cylindrical shape, and at the ends they have an annular groove for a sealant; protrusions with through holes are located on the outer contour of the end sections of the connection of the sidewalls and the shell; the end connection of the parts of the shell and sidewalls between themselves or with each other is made by preliminary tightening with bolts and nuts through their aligned through holes in the projections, as well as a continuous seam of plastic melt, made over the seal on the inside and outside.

Implementation of the invention

The modular tank contains a hollow body with a neck 8 (see Fig.1 - Fig.9), parts of which are made as a single unit, consisting of a shell 12 connected to it end sidewalls 1, a cover 7 of the neck 8, and the neck 8 of the body is placed on support formation of the upper surface of the housing. The modular tank and all its parts are made of polymeric material.

What is new is that the sidewalls 1 and the shell 12 are made as separate parts connected to each other by the ends.

The sidewalls 1 are made with the possibility of connection with each other both without a shell (see Fig.11) and with a shell (see Fig.8, Fig.9, Fig.10). In addition, the shell 12 itself is made with the possibility of connection with modules of the same type (see Fig.10).

At the same time, the end connection of the parts of the shell and sidewalls with each other or with each other is made (see Fig. 9) by preliminary tightening with bolts 20 and nuts 22 (if it is possible to use washers 21 between them) and a seam of plastic melt made over the seal with inside and outside. On the inside (see Fig.9) the internal seam 24 of the plastic melt is applied evenly over the entire diameter in one pass without visible defects (lack of penetration, pores, etc.). Similarly, the outer seam 19 of the plastic melt is applied - also evenly over the entire diameter in one pass without visible defects (lack of penetration, pores, etc.).

This design of the container, when connecting its parts, ensures its tightness.

To prevent corrosion of the bolted connection, all visible elements of the bolted connection 20, 21, 22 are covered with a thermal and moisture-resistant mastic or liquid rubber, which also increases the tightness of the connection of the container parts, since leakage can occur over time due to corrosion of metal elements.

The shell 12 and those sections 2 of the sidewalls 1 that are connected to it are made of a cylindrical shape.

At the ends of the shell 12 and the cylindrical sections 2 of the sidewalls 1 have an annular groove 14 (see Fig.1, Fig.6) for the seal 23 (see Fig.8 - Fig.11). The seal 23 ensures the tightness of the docking of the connected sections 1 and 12 of the tank with each other and with each other.

On the outer contour of the end sections of the connection of the sidewalls 1 and the shell 12 there are protrusions (see zone G of Fig.5) with through holes 11. Through the holes 11, for example, by bolting 20 or otherwise, the ends of sections 1 and 12 are tightly connected to each other or with each other, so that the sealant 23 fits snugly into the grooves 14 of the joined sections and serves as a gasket that prevents the liquid from escaping from the joints of the connected elements of the tank. As a seal 23, any rubber, plastic or silicone gasket in the form of a ring can be used, which fits snugly into the groove 14 of one section and protrudes from it so that the protruding part can also be tightly inserted into the groove 14 of another joined section.

This design of the tank design allows you to have a capacity, the volume of which can be increased by increasing the intermediate shell modules of the same type 12, from the shortest version without a shell (see Fig.11) to unlimitedly long with a large number of sections, for example, as shown in Fig.10 , from three sections of the shell, although there may be more.

A cover 7 of the neck 8 may be located on each sidewall 1 to provide ease of maintenance of the tank. For the same purpose, the cover 7 of the neck 8 can also be located on the shell 12.

To enhance the strength of the sidewall 1 may have meridional stiffeners 18 and transverse annular stiffeners 3. For the same purpose, the sidewall 1 may also have at least one horizontal stiffener 17.

Shell 12 may have transverse annular stiffeners 3.

In order to reduce the pressure of the body on the ground, in addition to the support leg 5 on which the tank rests, several meridional stiffeners 18 can be made in the form of a bulge (have a broadening 4), which forms a stop at the base. The presence of the leg 5 and the stop are optional, but desirable, especially when the tank is used with support on a solid foundation or placed on the surface.

In order to extract the individual elements of the tank, on the upper sections of the body of the sidewalls 1 and the shell 12, lugs with holes 13 can be made, with which hooks are hooked and individual elements are raised or lowered for installation / dismantling by a crane.

Before starting the assembly of the modular container, it is necessary to prepare a flat, solid, horizontal area, free from stones and construction debris.

The connection of the parts of the modular container is made in the following order.

First prepare the fastener kits. To connect two modules, select the required number of bolts 20 and nuts 22, and, if necessary, washers 21.

Combine two modules with holes for bolted connections. Components are inserted into the aligned holes 11 on one side, for example, in the following order: bolt 20, washer 21, on the other hand, a washer 21 is inserted and a nut 22 is screwed on. Similarly, fastener sets are installed along the entire length of the connection.

Then, over the entire diameter, the bolted joints are uniformly tightened with a force of not more than 100 Nm (so that the washer enters the container body a little).

After that, welds are made with plastic. Why prepare a manual extruder to work on heating 220-240 ° C, for welding use a PE rod with a diameter of 3-4 mm, depending on the equipment used.

Plastic welding is carried out at the junction points of the modules by a specialist who has access to this kind of work, from both sides - with the formation of an internal 24 and an external 19 seam. The welding sequence is not critical. The welding seams of the extruder should overlap each other by 50 - 100 mm to avoid leakage.

Before welding, the place where the modules are joined is thoroughly cleaned of dirt and degreased. Welds 19 and 24 are applied evenly over the entire diameter in one pass without visible defects (lack of penetration, pores, etc.). After welding on both sides, in order to prevent corrosion of the bolted joint, it is necessary to brush all visible elements of the bolted joint 20, 21, 22 with a thermal and moisture-resistant mastic (liquid rubber can be used instead of mastic).

These steps are repeated to connect the required number of modules.
