Description

The utility model relates to technical means of clothing service, namely to bath and laundry equipment, intended, among other things, for washing people in field conditions.

A known disinfection and shower unit (DDA-66) (Technical means of clothing service: Study guide - St. Petersburg: VAMTO, 2021) [1], (Disinfection and shower unit on the GA3-66 vehicle. Technical description and operating instructions - Moscow: Voenizdat, 1982) [2], mounted on the base chassis of the GA3-66 vehicle and designed to disinfect uniforms and wash people in the field. It consists of a steam boiler, a shower device, a steam-jet elevator, a boiler-accumulator, a shower device and a disinfection chamber.

The disadvantages of this technical means are the presence of a large number of components, units and assemblies, the assembly of which takes a lot of time. Before washing people, it is necessary to install two large tents, which is associated with certain difficulties when washing people in regions with constant snow cover. Also, this installation does not have the ability to carry a supply of water necessary for washing people, which necessitates the allocation of additional transport for the delivery of water in the absence of natural reservoirs.

A mobile field bathhouse is known (Patent of the Russian Federation RU 2106852 C1 "Mobile field bathhouse") [3], consisting of a hot water tank, a heating and shower device, a control panel, an instrument panel and a device for taking water, placed on the base chassis of the KAMAZ-43 10 vehicle, while this bathhouse additionally contains a cold water tank with an overflow pipe, a hot water tank with a chamber for creating steam and an overflow pipe, under which a firebox with a smoke pipe is located, and both tanks are connected at the outlet to water-dispensing shower mixers through collectors, and at the inlet - to the control panel, a device for taking water and to the instrument panel.

The above-described mobile field bath has a significant drawback, expressed in the fact that this technical means is not intended for use in regions with permanent high snow cover, due to the fact that it is mounted on a base chassis. This drawback significantly affects the entire range of activities associated with the operation of mobile shower units in regions with permanent high snow cover.

Also known is an amphibious vehicle (Patent 20120184159 A1 "Amphibious Vehicle") [4], comprising a tracked chassis having a frame and two controlled tracks attached to it and a hull mounted on the tracked chassis. The hull has positive buoyancy and has an adjustable ballast device inside, consisting of one or more tanks and a water pumping unit.

A significant disadvantage of this technical means is that inside the hull there is complex technological equipment, which allows for driving onto the ice from the surface position and driving off the ice when moving water from one ballast tank to another, while the useful internal space is significantly limited, which does not allow for the placement of technological equipment, which allows, among other things, washing the personnel of a small mobile group operating in isolation from the main forces in field conditions.

The closest prototype is a mobile complex for a repair or search team (Patent of the Russian Federation RU No. 2767222 C1 "Mobile complex for a repair or search team") [5], which includes a self-propelled chassis with passenger and technical compartments placed on it, equipped with heating and ventilation systems, fire extinguishing equipment, and life support equipment. In this case, a floating two-link tracked transporter with sealed technical and passenger compartments is used as a self-propelled chassis, wherein the technical compartment is placed on the first link of the transporter, and the passenger compartment is on the second link, in addition, the passenger compartment is made in the form of a residential block, with places for sleeping and resting, cooking and eating, life support system equipment in the residential block, devices for storing drinking water and water used in devices for personal hygiene of members of the repair or search team.

The disadvantages of the closest prototype are that the use of this mobile complex for washing personnel of a small mobile group operating in isolation from the main forces and performing tasks for a significant amount of time in field conditions is impractical and economically unprofitable.

The technical task of the utility model is to provide the ability to move across virgin snow in winter off-road conditions, including in difficult meteorological conditions, and to wash the personnel of a small mobile group operating in isolation from the main forces in regions with constant high snow cover.

The technical task is achieved by using a mobile shower unit for special climatic conditions, containing process equipment, a power plant, a transmission and a heat-insulated body, fixed on a tracked floating snow and swamp-going chassis designed for movement in deep snow. The heat-insulated body is divided by a metal partition into a process compartment, a washing compartment and a changing compartment.

The technical problem is solved due to the fact that the mobile shower unit for special climatic conditions contains a heat-insulated body, a power plant, a transmission, a metal partition and process equipment, including a boiler, a water tank, a fuel tank, a hand pump and a pipeline, while the metal partition divides the heat-insulated body into a process compartment, a washing compartment and a changing compartment, between which a door is installed. In addition, the process equipment is installed and fixed inside the heat-insulated body, placed on a tracked floating snow and swamp-going chassis, designed for movement on virgin snow in winter off-road conditions, including in difficult meteorological conditions.

The mobile shower unit for special climatic conditions comprises a tracked floating snow and swamp-going chassis (1) with a fixed heat-insulated body (4), power plant and transmission. This chassis (1) also has support rollers (3) on which the track (2) is put. The heat-insulated body (4) comprises front doors (6), a side door (5) and rear doors (7). A ladder (25) is fixed to the side of the heat-insulated body (4), closer to the rear left door (7) in the direction of travel, and a hatch (20) is installed on top. Inside, the heat-insulated body (4) is divided by a metal partition (15) into a technological compartment, a washing compartment (16) and a changing compartment (13), with a door (19) installed between the compartments. In the technical compartment, located at the rear of this body (4), a boiler (11), a water tank (10), a fuel tank (12) and a hand pump (22) are installed, while the boiler (11), the water tank (10) and the hand pump (22) are connected by a pipeline (8), on which there is a valve (23). Also inside the technical compartment there is a removable smoke pipe (21), which, when transferring this shower unit to the working position, is put on from above in the groove of the boiler (11). The fuel tank (12), located inside the technical compartment, has a neck (24) for convenient filling of the tank with liquid fuel, and the boiler (11) has a nozzle (14) for burning this liquid fuel when heating water inside the boiler (11). As an option, it is proposed to use the RI-5 m steam boiler as the boiler (11) of the mobile shower unit.

The heat-insulated body (4), front doors (6), side door (5) and rear doors (7) are covered on the inside with a layer of heat-insulating material (9) (as an option, with foam plastic obtained by foaming synthetic ?mols) and are covered with a lining made of thin sheet steel. A pipeline (8) with a shower head (17) at the end and a seat (18) are installed inside the washing compartment (16). A seat (18) is also installed inside the changing compartment (13).

The mobile shower unit for special climatic conditions has a tracked floating snow and swamp-going chassis (1) which is designed for movement not only in areas with permanent high snow cover, but also on marshy terrain, including in difficult meteorological conditions (as an option, UZOLA ZVM-2411, related to the class of chassis of especially high cross-country ability). This shower unit, having the above chassis, can freely move at a relatively high speed on weak-bearing surfaces, such as snow and ice, since this chassis has the lowest coefficient of specific pressure on the surface. Also, the above shower unit on a tracked floating snow and swamp-going chassis (1) can easily overcome climbs and descents with a steepness of up to 45 °, dips of up to 1 meter and low vertical obstacles, and in the event of a fall into an ice hole, it can float due to the rotation of the tracks.

The mobile shower unit for special climatic conditions operates as follows: if it is necessary to wash the personnel of a small mobile group operating away from the main forces in a region with permanent high snow cover, the driver fills a container (10) with water at the permanent deployment point of the main forces. After that, the mobile shower unit moves to the location where the small mobile group is performing its task. Upon arrival, the driver climbs onto the heat-insulated body (4), opens the hatch (20) and inserts the smoke pipe (21) into the groove of the boiler (11). At the same time, for ease of lifting onto the roof of the heat-insulated body (4) and descending from it, there is a ladder (25) fixed to the side. After that, he lights the nozzle (14) of the boiler (11), closes the valve (23) on the pipeline and, using the hand pump (22), pumps a small amount of water into the steam-jet elevator of the boiler (11). After the boiler has warmed up and the steam-jet elevator located inside the boiler (11) begins to suck water from the tank (10), the driver opens the valve (23) of the pipeline (8).

At the same time, air ducts are led from the bottom of the passenger compartment to the washing compartment (13) and the washing compartment (16), with the help of which warm air is supplied into the heat-insulated body (4) from the standard heater, which functions when the power plant is running, which allows maintaining a comfortable temperature inside the heat-insulated body (4).

At this time, a person from the small mobile group opens the side door (5), enters the changing compartment (13) and takes off dirty clothes. At the same time, due to the fact that the standard body has a height from the floor to the ceiling less than the height of an average person, it is recommended to use the seat (18) located inside the changing compartment (13) when undressing.

Cold water sucked in by the elevator from the water tank (10) is mixed with steam, heated and supplied via the pipeline (8) located in the washing compartment (16) to the shower head (17). In doing so, the person opens the door (19) and enters from the changing compartment (13) into the washing compartment (16). He opens the tap of the shower head (17) and takes a hot shower, using the seat (18). The used water is removed by gravity during the shower through an opening located in the corner of the washing compartment (16) in the floor, which has a slope towards the opening. After taking a shower, the person closes the tap on the shower head (17) and moves back to the changing compartment (13), dries himself and puts on clean clothes. Then he exits through the side door (5) from the heat-insulated body (4) of the mobile shower unit, after which the next person enters to take a shower. And after the entire personnel of the small mobile group operating in isolation from the main forces has taken a shower, the driver closes the nozzle valve (14), closes the valve (23) supplying water from the tank (10) to the boiler (11) through the pipeline (8). He climbs onto the roof of the heat-insulated body (4), removes the smoke pipe (21) and closes the hatch (20). He places the smoke pipe (21) in the technological compartment, closes the rear doors (7) and leaves for the parking place.

Assembly of a mobile shower unit for special climatic conditions involves preliminary thermal insulation from the inside of the standard body, front doors (6), side door (5) and rear doors (7) with thermal insulation material (9) and cladding with thin sheet steel. The floor of the insulated body (4) is covered with sheet steel. A ladder (25) is installed on the side of the insulated body (4), and a hatch (20) on top. Next, a metal partition (15) divides the insulated body (4) into a technological compartment, a washing compartment (16) and a changing compartment (13). Then, the technological equipment is installed and rigidly fixed, which includes a boiler (11), a water tank (10), a fuel tank (12), a hand pump (22) and a pipeline (8) inside the technological compartment located at the rear of the insulated body (4) behind the rear doors (7). In this case, the water tank (10), hand pump (22) and boiler (11) are connected by a pipeline (8). Inside the washing compartment (16), a pipeline (8) coming out of the boiler (11) is fixed, at the end of which a shower head (17) is installed. A seat (18) is also installed for the convenience of taking a shower. Inside the changing compartment (13), a seat (18) is also fixed, and a door (19) is installed between the compartments.

Thus, the presented mobile shower unit for special climatic conditions has a relatively simple and reliable design, is new and has new technical characteristics and differs significantly from prototypes, providing the ability to move on virgin snow in winter off-road conditions, including in difficult meteorological conditions and to wash the personnel of a small mobile group operating in isolation from the main forces in regions with constant high snow cover. This mobile shower unit for special climatic conditions can be used in the rear units of the Ministry of Defense or other security agencies when washing the personnel of a small mobile group performing assigned tasks in areas with constant high snow cover, including in difficult meteorological conditions.
