Description

The utility model relates to transport engineering, mainly to spare parts, tools and fixtures, providing quick and high-quality maintenance of engine systems of multi-purpose tracked vehicles.

To measure the fuel level, an electric lever-type sensor with a rheostat is known [Ural 4320, Ural 4420 tractor vehicles and their modifications [Text]: Technical description and operating instructions / editor V.I. Korolev, tech. Editor V.O. Tokareva, proofreader G.A. Paranina. - [3rd ed.] - M.: Military Publishing House, 1986. - 304 p. - Bibliography: 302-304], [KAMAZ all-wheel drive vehicles [Text]: Design and operation / edited by D.Kh. Valeev - Naberezhnye Chelny, 2006. - 635 p. - Bibliography: 631-633], designed to inform the driver about the amount of fuel in the tank, as well as about reducing the fuel supply to the reserve supply. The principle of operation is based on a change in the resistance of the rheostat, the slider of which is driven by the position of the float, depending on the fuel level in the tank, an indication of the decrease in fuel to the reserve is carried out due to the presence of a contact output to the control lamp. The pointer scale is given in fractions of a full refueling.

The structural disadvantages of this sensor are the following factors:

- basically, the operation of armored weapons is associated with off-road traffic with hard or improved pavement, on impassability, in terrain with a lot of ups, downs, slopes with significant ditches and other natural and artificial obstacles, during the movement there are sharp accelerations and brakes of the car . When moving in such conditions in the fuel tanks of military vehicles there are significant and sharply-variable changes in the angle of inclination of the fuel. Sharp, with large amplitudes, oscillations of the float on the one hand cannot allow the correct readings to be taken from the sensor during movement, and on the other, can lead to breakdown of the contact mechanism of the sensor;

- on BMD, BTR-D and machines using their base, such sensors are not installed.

It consists of TI-2 meters (for the left tank), IT-3 (for the right tanks), an M-13 60-11 pointer, powered by the vehicle’s on-board network, operating on changing the electric capacity of the sensors depending on the amount of fuel in the tank. The scale is given in fractions from a full refueling.

The disadvantages of this fuel gauge are:

- data on the presence of fuel in the tanks is given in fractions of a full refueling, which can only orient the driver while driving on the need for refueling;

- to determine the approximate total fuel supply it is required to switch the tanks, and summarize the results;

- to determine the exact amount of fuel poured into the fuel tanks, use a dipstick to measure the level of fuel and oil;

- installed on machines of later generations - BMD-3 (4).

Book 2, part 2, 1985. - 228 p. - Bibliography: 2-6], [Product 950 [Text]: Picking list]. The probe is made of aluminum strip with a handle in its upper part for ease of use. The dipstick is calibrated to measure the fuel level in the left fuel tank, in the right group of fuel tanks, to measure the level of coolant (water, antifreeze), the oil level in the oil tank, and the fluid level in the hydraulic tank.

The structural disadvantages of this probe are the following factors:

- in low light conditions in storages with military equipment, at dusk and at night, the trace left by light oil products (diesel fuel, hydraulic fluid), coolant (water, antifreeze) are virtually indistinguishable on the probe, which leads to repeated measurements;

- on the machines of the combat operation group during short-term storage with airborne assets loaded on them, making measurements with the probe becomes even more difficult and requires additional effort and time (the installation sites and the unfolded links of the parachute systems interfere with the measurements).

The dipstick for measuring the level of fuel, oil and coolant included in the set of individual spare parts BMD-1 (2), BTR-D, BMD-3 (4) is taken as a prototype.

Thus, in connection with the described shortcomings of sensors, probes or the inability to use them on the BMD, there is a need for the BMD, BTR-D and machines based on them, to create a universal device, cheap to manufacture, easy to use, reducing labor costs when measuring fuel level and coolant. Such a device, especially for vehicles of a combat operation group, which are in short-term storage with loaded parachute systems, can become a serious alternative to the probe and rods.

The technical result of the use of a fuel and coolant level indicator in the capacities of internal combustion engine systems (hereinafter for simplicity - an indicator) is aimed at reducing the labor costs and time required to perform work on measuring the fuel and coolant level when carrying out work to monitor the technical condition of a combat vehicle and during its maintenance; for high-quality and quick execution of work on preparation for removal from short-term storage and preparation for use.

The technical result is achieved by the fact that the indicator containing the probe, calibrated “water”, “antifreeze”, “fuel”, is additionally installed in it: a slider consisting of a housing, a cover, a ground contact (three disks) installed in battery pack, switch, latch with ball, slider and pointer; an electrical circuit consisting of two batteries, red and green LEDs, green and red LED contacts, a switch, a ground contact, and connecting wires; the probe is made of dielectric material.

Distinctive features of the prototype are the following: a runner, consisting of a housing, a cover, a ground contact (three disks), a battery pack installed in it, a switch, a latch with a ball, a slider and a pointer to limit the movement; an electrical circuit consisting of two batteries, red and green LEDs, green and red LED contacts, a switch, a ground contact, and connecting wires; the probe is made of dielectric material.

The indicator (figure) consists of a probe 1 with a graduation of 2 “fuel”, “water”, “antifreeze”, a slider with a cover 3, three contact disks “mass” 4, a switch 5, a battery pack 6, a latch with a ball 7, slider 8, pointer 9, red LED 10, green LED 11, contact of the red LED 12, contact of the green LED 13, connecting wires 14.

The indicator works as follows: set, by moving the slider 3 along the axis of the probe 1, pointer 9 opposite the graduation of the liquid that will be measured, and lower the indicator into the fuel filler neck (expansion tank) so that the lower contact disk 4 enters the neck as a guide, and the disk 4 located above it made contact with the neck of the tank. Turn on the switch 5 on the cover of the slider 3. When the green LED 11 lights up, the liquid level corresponds to the norm (full charge), the red LED 10, at the same time as the green 11, the liquid is above normal, the non-burning LEDs indicate a low liquid level or her absence.

Due to the use of electricity with open contacts, the indicator cannot be used to measure the fuel level on machines that use gasoline as fuel.

The use of the indicator significantly reduces the time and reduces the complexity of the work on measuring the level of fuel and coolant during the work of monitoring the technical condition of the combat vehicle and during its maintenance. One device per unit will be enough to quickly and accurately perform a check of the fuel and coolant levels on military vehicles during a park or park-business day, during inspections and inspections.

The use of the indicator allows you to reduce time, without loss of quality of work, in the preparation of BMD, BTR-D for removal from short-term storage and preparation for use.

The indicator can also be useful when refueling (refueling) or checking military vehicles in the dark or in the absence of lighting at the place (during) refueling or checking military vehicles in the field.

The indicator, while maintaining its circuit diagram, can be performed for any other technique where the distance from the surface of the liquid being measured to the upper edge of the filler neck, as well as when extending and calibrating the stem, is known, use it as a level gauge (except gasoline) for any tank.
