Abstract

FIELD: mechanical engineering.

SUBSTANCE: invention can be used in a motor pump with a gasoline engine. The fire-military motor pump consists of a centrifugal fire pump, a bearing frame of an internal combustion engine assembly, a fuel tank, a pressure pipe with a pressure valve, an engine control unit, a protective hood and a manual vacuum pump. The chassis is removable and consists of a handle (1), a connecting rod (2), a wheel axle (3), two wheels (4) and a locking element (6). The handle (1) is a metal pipe that makes it possible to hold it with two hands. The wheel axle (3) is connected to the connecting rod (2). Grooves for mounting a removable chassis and a folding rod with a lantern for lighting the working area are mounted on the supporting frame. Folding handles for carrying are mounted on the frame at the maximum width of the motor pump in the front and the rear.

EFFECT: increase in the safety of transporting the motor pump and increase in the speed of carrying the motor pump in narrow doorways.

Description

The proposed motor pump is a portable, non-high-pressure (conventional) motor pump with a gasoline engine. Motorized fire pumps are used at the points of permanent deployment of military units and subunits, as part of field camps, temporary residences, in warehouses, arsenals and other objects subject to fire protection.

Known Russian-made motor pumps MP-13/80 "Geyser" on a skid with a VAZ 11113 engine [1], MP-10/60 "Aquarius" with a HONDA GX-630 engine [2], MP-13/80 "Geyser" on a manual a bogie with a VA3-2103 engine and an automatic piston-type vacuum system [3], an MP-800/80 with a two-stroke gasoline engine PM3-640 [4]; Chinese-made Zongshen HG 30 motor pump [5], LIFAN 40ZB60-4.8QT fire motor pump [6]; Japanese-made Tohatsu VF 53 AS [7].

The most suitable device is the motor pump MP-800/80 [4] of the Liven fire-fighting engineering plant, which was chosen as the prototype. The well-known sample of the motor pump MP-800/80 - the prototype [4] consists of a centrifugal fire pump, a supporting frame of an internal combustion engine assembly, a fuel tank, a pressure pipe with a pressure valve, an engine control unit, a protective hood, a manual vacuum pump.

However, the well-known sample of the motor pump MP-800/80, due to its imperfect design, has a number of technical shortcomings that do not allow the full potential and technical capabilities of the motor pump to be used at facilities, taking into account the characteristics of the military infrastructure, and deprives it of a number of advantages over competitors, namely: product design [ 4] does not allow transportation by one operator, the location and design of the available carrying (transportation) handles does not allow you to quickly and safely pass through narrow doorways, the lack of a lamp to illuminate the working area makes it difficult to work in the dark.

The technical objective of the invention is to expand the functionality of the motor pump [4] by improving and changing the design for use for its intended purpose at military infrastructure facilities, taking into account their features.

The essence of the claimed technical solution lies in the fact that the fire motor pump - military, consists of a centrifugal fire pump, a supporting frame of an internal combustion engine assembly, a fuel tank, a pressure pipe with a pressure valve, an engine control unit, a protective hood, a manual vacuum pump. At the same time, the chassis is made removable and consists of a handle, which is a metal pipe that allows you to hold it with two hands, a connecting rod, a wheel axle, two wheels, and a fixing element, the wheel axle is connected to the connecting rod, grooves are mounted on the carrier frame for attaching a removable chassis and a folding bar with a lantern to illuminate the working area, folding handles for carrying are mounted on the frame already at the maximum width of the motor pump in front and behind.

Thus, the task is solved by upgrading some of the constituent parts of the motor pump, namely:

- installation of a removable chassis for transporting the motor pump by one operator, while the wheel axle of the chassis must enter the grooves mounted on the frame of the motor pump and be fixed;

- installing a removable wheel axle closer to the center of gravity in such a way that the motor pump frame in front of the wheels makes it easier to drag the motor pump on uneven surfaces;

- installation of folding handles for carrying the motor pump in dimensions significantly smaller than the dimensions of the motor pump itself, so as not to damage the hands of operators when passing through narrow openings;

- installation of a lantern, on a folding bar, the height of which in the folded state does not increase the overall dimensions of the fire-military motor pump.

The technical result of the claimed technical solution is to expand the functionality of the prototype motor pump. The invention is illustrated by drawings, where:

Figure 1 - removable chassis for moving the motor pump fire - military one operator;

Figure 2 - a fragment of the supporting frame of a fire pump - military (lower part, side view);

Figure 3 - fire motor pump - military (front view).

The proposed design of a motor pump fire - military is:

In FIG. 1 shows a removable chassis for moving a fire engine - military pump by one operator, the chassis consists of a handle (1), a connecting rod (2), a wheel axle (3), two wheels (4), a locking element (5).

The handle (1) is a metal tube that allows you to comfortably hold it with two hands. The connecting rod (2) is a metal pipe with a bend (8). The wheel axle (3) is a metal pipe with a length slightly wider than the maximum width of the motor pump, it has retainers-limiters (6) made in the form of metal washers mounted on the wheel axle. The wheels (4) are fixed on the wheel axle (3), in the middle the wheel axle (3) is connected to the connecting rod (2). The fixing element (5) is any device that allows you to quickly fix the motor pump frame to the chassis.

In FIG. 2 shows a fragment of the supporting frame of a motor pump for a fire fighting and military service (lower part, side view). A groove (12) for fastening the wheel axle (3) is mounted in the frame structure on both sides, the groove (12) is mounted in such a way that the wheel axle (3) is as close as possible to the center of gravity of the motor pump.

In FIG. 3 shows a fire motor pump - military (front view). For the convenience of carrying the motor pump in narrow passages and doorways, handles (11) are mounted on the frame (10) (front and rear), made in a folding design with fixation from arbitrary folding. The handles (11) are mounted significantly narrower than the maximum width of the fire-military motor pump, to prevent injury to hands when carried in narrow openings, in the same way two handles (11) are located on the back of the frame, to illuminate the working area at night on the frame of the fire motor pump - military mounted folding bar (14) with a lantern (13). The rod (14) when folded should not exceed the maximum size of the fire engine - military pump itself.
