Description

The invention relates to technical means of transportation and short-term storage of drinking water in various natural and climatic conditions.

Known tank (Tanker model 4615-01 (ATsPT-4,7) http://www.zavod-start.ru/tanker/food/4615-01) [1], designed for transportation and short-term storage of food liquids (milk, drinking water), with a density of not more than 1.03 g / cm ³ , it consists of a thermally insulated tank, a pump, a cover and filling-drain pipelines.

The main disadvantages of the prototype is the lack of the possibility of taking, transporting, maintaining and distributing water in the regions of the Far North and the Arctic.

The technical objective of the invention is to make it possible to transport, maintain, withdraw and dispense water in regions with low ambient temperatures in offline mode.

The technical problem is solved due to the fact that a device for storing and maintaining water in regions with low ambient temperature in offline mode, consisting of a thermally insulated tank, a pump, a cover and a filling-draining pipeline, characterized in that inside the body of a thermally insulated container body there is a constant volume with an aggregate compartment and a technological compartment, a container is rigidly fixed to the floor with a saddle support and a tape clamp, on the outer side of which a grid is fixed, on which an electric heating cable is fixed with a fastener, and a heat-insulating layer of polyurethane foam is applied, the supply of warm air into the body is provided by heating - a ventilation unit connected via an electric wire to a diesel generator set.

In FIG. 1 shows a side view of a device for storing and maintaining water in special conditions, showing: pos.1 - body; pos.2 - quick detachable connection; pos.3 - pump; pos.4 - saddle support; pos.5 - heat-insulating layer; pos.6 - breakwater; 7 - distributing column; pos.8 - water level sensor; pos.9 - pencil case; 10 - heating and ventilation unit; pos.11 - cover; 12 - switching device; pos. 13 - electric heating cable; pos.14 - capacity; 15 - diesel generator set;

In FIG. 2 - shows a top view of the device, where it is indicated: pos.16 - crane; pos. 17 - plug; pos. 18 - filler neck; 19 - tape clamp; pos. 20 - filter-ventilation unit; pos. 21 - racks for spare parts; pos. 22 - technological equipment for water distribution.

The essence of the invention lies in the fact that the storage of water under special conditions in the proposed device is based on compensation for heat losses of the heating system and thermal insulation of the container body and the container itself by including a heating and thermal insulation layer in its design.

A device for storing and maintaining water under special conditions structurally consists of a body (1) (as an option, a thermally insulated container body of constant volume KK 6.2) with a compartment (as an option, two thermostatically controlled ones: aggregate and technological), provided with a heating system, power supply, fire extinguishing , drain-filling and ultraviolet disinfection of water.

Inside the body (1), a container (14) is fixedly fixed (as an option, a cylindrical shape made of food grade stainless steel with a wall thickness of 2 mm, for water). The immobility of the container (14) inside the body (1) is ensured by its rigid fixation to the floor using a band clamp (19) (as an option, three) and a saddle support (4), the band clamp (19) wraps around the container (14) and is fixed to the saddle support (4) on which it is placed. Embedded elements are included in the structure of the floor of the body (1), in which the saddle support (4) is bolted.

The supply of electricity for the functioning of the systems and the operation of the pump (3) (as an option, a vortex, type SVN-80A, self-priming pump, nozzle diameter 80 mm), which provides intake, supply and pumping of water, is carried out from a diesel generator set (15) (as version, DGU8-P27.5-VM1, power 8 kW), rigidly (bolted) fixed in the aggregate compartment.

The loading-draining system includes a dispenser (7) with a pump (3); a system of shut-off and control devices (ball valve (16) (as an option, ball valves), shut-off dampers, pipeline valves, shut-off valves with a diameter of 50 mm, Bogdanov's GP 50-80 adapters, Camlock-type quick coupling); sleeves for water supply from composite materials (bend well and keep the temperature) with a diameter of 50 mm; filling limiting system with overflow protection (water level sensor (8) (as an option, type PMP-052 with "dry" contacts)).

Tank heating system (14) includes: electric heating cable (13) (as an option, type 31 RV), fasteners for fixing the cable to the steel mesh; junction boxes, control system and power supply and thermoregulation. It is mounted directly on the container (14) while the cable passes around the circumference of the container (14) in turns.

The estimated distance between the turns is 12-15 cm. A switching device is provided to connect the electric heating cable to the power network. At the same time, switching ensures the use of not only mobile power plants, but also stationary electrical networks. To connect to an external network, the spare parts kit includes a power cable 45 m long and a grounding device. The use of a cable of this particular brand is determined by its linear power, which is higher than the linear power of analogues (11VR, 17VR, 27VR).

The walls of the body (1) are made as a result of the composition of materials: aluminum sheet - 2 mm (external), polyurethane foam - 90 mm and glass composite material - 2 mm (internal) without joints in a single sandwich structure. This ensures operation of the device at operating ambient temperatures from minus 60°С to plus 50°С, relative air humidity up to 98%, wind speed up to 30 m/s.

As a result of the experimental studies, it was found that:

1. The proposed system for compensating heat losses and maintaining the temperature of the liquid up to 10°C at an ambient temperature down to minus 30°C does not require turning on the heating system.

2. Processing the tank with rigid polyurethane foam and forming a heat-insulating layer on the surface of the tank with a thickness of 100 mm ensures the ease of flow around complex, non-standard contours, valves, valves; corrosion protection; minimum coefficient of thermal conductivity; high rates of frost resistance; ease of restoration of the damaged layer; creation of a seamless, monolithic coating.

3. Compensation (reduction) of heat losses is provided by thermal insulation with a layer of polyurethane foam, which has a closed porous structure and provides low thermal conductivity (0.019-0.003 W/m), low weight (45-60 kg/m3) and has high adhesion ( ¹ .5 kg / cm ² ) with metals. The heat-insulating layer is arranged over the electric heating cable, which is structurally combined into a flexible mat by connecting the turns with a mounting wire.

Placing a device for storing and maintaining water under special conditions in a standard container body makes it possible to transport it on an automobile or tracked base chassis, as well as by rail, aviation (including on the external sling of a helicopter), river and sea transport.

Thus, the proposed technical solution is distinguished by novelty and new useful qualities, which provide the possibility of transporting, maintaining, withdrawing and dispensing water in regions with low ambient temperatures in an offline mode. The proposed technical solution can be used in the interests of law enforcement agencies.
