RU237828U1 - AMPHIBIOUS AIR-CUSHIONED LAUNDRY UNIT - Google Patents

Abstract

This utility model pertains to technical equipment for the clothing service, specifically to technical equipment designed for washing linen and uniforms in the field. The technical objective of the utility model is to enable movement in off-road winter conditions in regions with persistently high snow cover along a route that includes rivers subject to ice formation or drift and lacking bridges (crossings), furthermore, in adverse weather conditions. This capability also enables the washing and ironing of linen and uniforms for members of a small mobile group operating separately from the main forces in the field in terrain with persistently high snow cover. This technical objective is achieved through the use of an amphibious laundry unit on an air cushion, comprising a platform with ladders, a handrail, flexible fencing, a wheelhouse, a power plant, a propeller, fans, and a heat-insulated body, within which the laundry equipment is rigidly secured. The technical challenge is solved by integrating an amphibious air-cushion laundry system with laundry equipment, including washing machines, an ironing machine, a gasoline generator with a separate tank, and a water supply system consisting of a water tank, a water pump, and a pipeline rigidly connecting the water tank, water pump, and washing machines, all housed within a thermally insulated body. The thermally insulated body is rigidly fixed to the central portion of the platform, which features a flexible enclosure, a wheelhouse, a handrail, ladders, a power plant, fans, and a propeller enclosed by a casing.

Description

The utility model relates to technical means of clothing service, namely to technical means that are intended for washing linen and uniforms in field conditions.

A mechanized small-sized laundry MMP-2M is known (“Technical means of clothing service”. Textbook. - Volsk: VVIMO, 2018) [1], (“Technical description and operating instructions for MMP-2M”. - Moscow: Voenizdat, 1991) [2], containing laundry equipment, which in the stowed position is placed on two trailers, while the laundry unit is mounted on a 2-P-5.5 trailer, and a mobile power station EDS-30-T / 400 with a set of portable cables for power and lighting networks, included in the MMP-2M laundry kit, is mounted on a 2-PN-2 trailer. The laundry unit includes a KP-019 washing machine, a KPA-500Zh boiler unit, a Ts-25 centrifuge, and a drying machine
KP-306A, compressor, pumping station and rubber tank RDV-5000.

Also known is the mechanized field laundry MPP-9, designed for washing, drying and ironing linen and uniforms of personnel in field conditions [1], (“Mechanized field laundry MPP-9”: Study guide. - Volsk: VVIMO, 2014) [3], containing two variable-volume container bodies (washing and drying sections), two constant-volume container bodies (heating station and spare parts module), three M-30 tents and an ESDL-100T-400-1RK power station.

The above-described designs share significant drawbacks, including their multiple components and the time required to deploy them. The use of these laundry systems is impractical in locations where small mobile teams operate separately from the main forces, as these laundries use high-tech equipment that requires additional training for maintenance personnel. These systems also cannot be used in areas with deep snow cover, as the equipment is mounted on trailer-mounted chassis.

The closest prototype is a mobile laundry unit for special climatic conditions (Patent of the Russian Federation RU No. 229735 U1, "Mobile laundry unit for special climatic conditions") [3], containing a power plant, transmission, chassis, heat-insulated body, metal partitions and technological equipment, including a washing machine, an ironing roller, a gasoline generator with a separate tank and a water supply system. In this case, the technological equipment is rigidly fixed inside the heat-insulated body, placed on a tracked floating snow and swamp-going base chassis, designed for movement on virgin snow in winter off-road conditions, including in difficult meteorological conditions, and the water supply system consists of a water tank, a water pump and a pipeline, which rigidly connects the water tank, water pump and washing machine in series.

A significant drawback of the closest prototype is its limited suitability for travel along routes that include rivers experiencing ice formation (or drifting ice) and lack bridges and crossings, in winter off-road conditions, and in adverse weather conditions for transporting a small mobile team to a designated point for washing and ironing linen and uniforms, performing field tasks isolated from the main forces in terrain with persistently high snow cover. Thus, the aforementioned mobile laundry unit for special climatic conditions, which has a tracked, floating, snow-and-swamp-going base chassis, such as the UZOL ZVM-2411 variant, which is classified as a high-cross-country base chassis, cannot be used during freeze-up or drifting ice on rivers encountered along the routes, as it could be seriously damaged during amphibious travel and subsequently submerged.

These shortcomings significantly affect the entire range of activities associated with the operation of laundry installations in areas with constant high snow cover.

The technical objective of the utility model is to enable movement in off-road winter conditions in regions with constant high snow cover along a route that includes rivers where ice has formed or where ice is drifting and where there are no bridges (crossings), and also in difficult meteorological conditions, and to carry out washing and ironing of linen and uniforms of people in a small mobile group operating in isolation from the main forces in field conditions in areas with constant high snow cover.

The technical task is achieved by using an amphibious laundry unit on an air cushion, which has a platform with stairs, a handrail, a flexible fence, a wheelhouse, a power plant, a propeller, fans and a heat-insulated body, inside which the laundry technological equipment is rigidly fixed.

The technical challenge is solved by integrating an amphibious air-cushion laundry system with laundry equipment, including washing machines, an ironing machine, a gasoline generator with a separate tank, and a water supply system consisting of a water tank, a water pump, and a pipeline rigidly connecting the water tank, water pump, and washing machines, all housed within a thermally insulated body. The thermally insulated body is rigidly fixed to the central portion of the platform, which features a flexible enclosure, a wheelhouse, a handrail, ladders, a power plant, fans, and a propeller enclosed by a casing.

The amphibious air-cushion laundry unit comprises a platform (10) with a flexible enclosure (1), onto which the wheelhouse (2), handrail, power plant (6), fans (11), crankcase propeller (8), ladders (4) and a heat-insulated body (3) are fixed on top. Headlights (5) are mounted on the wheelhouse (2). The heat-insulated body (3) has roller shutters (14) in the bow section and an external body heater (28) in the stern section. A hatch (13) is fixed on top of this body (3), a door (15) and a vertical ladder (27) are mounted on the right in the direction of travel, and there are windows (30) on the sides of the walls. The heat-insulated body (3) is divided internally by a metal partition (24) into a technological compartment and a laundry section. In the stern part of the platform (10) of the amphibious laundry unit on an air cushion, behind the power plant (6) there is a casing (8), inside which the blades (12) of the cruise propeller rotate, and the rudders (9) are fixed at the rear. Inside the technological compartment, the gasoline generator (19), the fuel tank (20) with a filler neck (21), and the water supply system, consisting of a water tank (16) with a filler neck (17) and a filler cap (18), a water pump (22), and a pipeline (23) are rigidly fixed. In this case, the pipeline (23) rigidly connects the water tank (16), the water pump (22) and the washing machines (25) in series. The heat-insulated body (3) and the door (15) are covered on the inside with heat-insulating material (29) and lined with thin sheet steel. The laundry department is equipped with laundry equipment, including washing machines (25) and an ironing machine (26). The washing machines (25) are rigidly connected to the pipeline (23) exiting the technological department.

Windows (30) are designed to provide additional natural lighting for the laundry area during daylight hours and, if necessary, to ventilate the area after washing and ironing.

Headlights (5) are designed to illuminate the area in front of this amphibious laundry unit when moving at night.

The air cushion is a layer of compressed air under the platform (10) of this laundry unit, raising it above the surface of water or land. The absence of friction with the surface reduces resistance to movement. The ability of the above-described laundry unit to cross various obstacles on land, waves on the water, passing over them, as well as rivers on which ice has formed or is drifting and where there are no bridges (crossings) depends on the lifting height (“Air cushion vessel” [Electronic resource]: https://ru.wikipedia.org/wiki/Судно_на_воздушной_подушка) [4]. The air cushion of this amphibious laundry unit is formed by a chamber method, in which air, pumped by fans (11) under a dome-shaped bottom, which is covered with a flexible fence (1), flows freely along its perimeter, and the greater the air supply, the higher this laundry unit rises. The amphibious air-cushion laundry unit can glide over water, snow, ice, and heavily swamped terrain, using the traction provided by the high-speed rotating propeller blades (12). Torque is transmitted from the power plant (6) to the propeller via the propeller shaft (7). The rudders (9), mounted aft of the casing (8), rotate to propel the laundry unit in the desired direction.

The crew of the amphibious laundry unit on an air cushion is expected to consist of two people, a driver and an operator.

As an option for washing machines (25), it is suggested to use the Biryusa WM-SC1214/15S washing machine.

As an option, it is suggested to use the Miele B 995D ironing roller as an ironing roller (10).

The amphibious air-cushion laundry unit operates as follows: when it is necessary to wash dirty linen and uniforms of personnel of a small mobile group operating separately from the main forces in a region with permanently high snow cover, the laundry unit operator at the permanent deployment point of the main forces fills the tank (16) with water, having first opened the hatch (13) and the filler cap (18). For ease of access to and from the insulated body (3), it is recommended to use the vertical ladder (27). He then fills the fuel tank (20). At this point, the driver turns on the external heater (28) to ensure that by the time the insulated body (3) arrives at the assigned mission location, the temperature inside the insulated body (3) is comfortable for washing and ironing the linen and uniforms.

The amphibious air-cushion laundry unit then moves to the small mobile group's designated mission location along a route that may include rivers with ice drift or forming ice sheets and no bridges or crossings. Upon arrival at the designated location, the laundry unit operator opens the roller shutters (14) in the forward section of the insulated body (3). He then starts the gasoline generator (19) and turns on the power to the water pump (22), washing machines (25), and ironing machine (26). Then, entering the laundry compartment through door (15), the laundry unit operator places dirty laundry or uniforms in the washing machines (25) and sets the required washing programs. Water from tank (16) is supplied to the washing machines (25) using water pump (22). After washing, the washing machines (25) wring out the wet laundry or uniforms. The laundry operator then places the washed linen or garment into the ironing mangle (26) for subsequent ironing.

The assembly of the amphibious laundry unit on an air cushion involves preliminary thermal insulation of the standard body (3) and door (15) from the inside with a layer of thermal insulation material (29) (as an option, with foam plastic obtained by foaming synthetic resins) and lining them with thin sheet steel. The floor of the thermally insulated body (3) is also covered with sheet steel. Next, a metal partition (24) divides the thermally insulated body (3) into a technological compartment and a laundry section. Then, the washing machines (25) and the ironing roller (26) are installed and rigidly fixed in the laundry section inside the thermally insulated body (3). And in the technological compartment of this body (3), the water tank (16), water pump (22), gasoline generator (19), tank (20) and pipeline (23) are rigidly fixed. After this, the heat-insulated body (3) is installed in the central part of the platform (10), which has a wheelhouse (2), a handrail, a power plant (6), fans (11), ladders (4) and a propeller, which is closed by a casing (8) having rudders (9).

Thus, the presented amphibious laundry unit on an air cushion has a relatively simple and reliable design, possesses novelty and new technical characteristics and differs significantly from prototypes, providing the ability to move in winter off-road conditions in regions with a permanent high snow cover along a route that includes rivers on which ice has formed or ice has drifted and there are no bridges (crossings), moreover, in difficult meteorological conditions and to carry out washing and ironing of linen and uniforms of people of a small mobile group, operating in isolation from the main forces in field conditions in terrain with a permanent high snow cover. This amphibious laundry unit on an air cushion can be used by rear units of the Ministry of Defense or other security agencies in regions with constant high snow cover, with full-flowing rivers that can freeze or drift, for washing linen and uniforms of personnel of small mobile groups operating separately from the main forces in field conditions, including in difficult weather conditions.
