Description

The invention relates to the fields of road and housing and communal services, technologies for removing snow, ice, mud and debris, specifically to methods and means of clearing and evacuating heavily snow-covered parked cars.

Until now, the clearing of heavily snow-covered (in snowdrifts) parked cars is carried out by car owners themselves and with improvised means - shovels and hand-held brushes (1. RU 2611305, A46 B 15/00, etc., 21.02.2017).

However, this method has the following disadvantages:

- manual mechanical cleaning (with a shovel and a sweep) is very laborious, time-consuming, uncomfortable in conditions of gas pollution, dangerous on the roadway and, despite recommendations to combat physical inactivity and increase employment of the population, especially labor migrants, does not cause enthusiasm among the mentioned car owners ; it is not the responsibility of the utilities,

and mechanization is unattainable in the foreseeable future due to the complex configuration of the vehicle being cleaned and the possibility of its mechanical damage;

- manual mechanical cleaning, not by the car owner himself and without his knowledge, is inevitably associated with a high probability of mechanical damage to the vehicle being cleaned (primarily glass parts, paintwork and polished surfaces), individual and collective irresponsibility (as well as deliberate harm) of the participants in the operation;

- the potential capabilities of the fleet of special vehicles, tractors and other equipment (including water injection devices) available in the urban and rural road and housing and communal services are not used.

At the same time, this, in particular, complicates the forced evacuation of such vehicles in a state of disrepair, because clearing is not included in the duties of the tow truck driver.

Known mechanized and electrified snow blowers - auger, brush and pneumatic, for example, a pneumatic transport installation for removing snow from the roofs of houses and households. buildings, as well as a snowblower with a rotary blowing system [2. RU 195081 U1, E04D 13/076 and others, 15.01.2020; 3. RU 2658385, E01H 5/00 and others, 21.06.2018].

But the development of small-scale mechanization practically did not touch on this problem, since the mechanical principle, as a rule, is not compatible with the complex configuration of cleaning objects (especially if the work is carried out by a device on a car or tractor chassis), and pressurized air is ineffective in dense snow and is "powerless" in availability of ice, plus it is far from being cost-effective for every car owner.

The use of cold water under pressure has been widely known for a long time: - in the road and housing and communal services for watering surfaces of paved roads and pedestrian roads, flower beds, lawns, shrubs, trees, roadside poles, billboards, road signs, fences and non-professional suppression of places of local fires (garbage dumps, sheds, etc.), use watering and watering machines based on trucks and tractors of small traction class ("Belarus", etc.), including the corresponding functions of universal heavy-duty auto complexes [4.

- in firefighting for professional extinguishing of fires, and sometimes (in fact) washing a freestanding car, fire trucks are used with powerful water cannons and tanks for water supply [6.

What will happen if the car is washed with a fire hose? - URL: https://topautotube.ru/tags/firefighters/ (date of publication: 27.07.2016; date of access: 23.04.2020)];

- in the field of ensuring law and order to disperse unauthorized demonstrations, rallies and pickets, they use police cars with water cannons installed on them (analogue of a cannon) [8. A special car to disperse BAZ demonstrations Avalanche - this is a technique! - URL: https://zen.yandex.ru/media/id/5c279369fa137100aab4a6f8/specavtomobil-dlia-razgona-demonstracii-baz-lavina-vot-eto-tehnika-5da41f2398fe7900ad798eff (published date: 10/23/2019; access date .2020)].

The general disadvantages of such methods are the corresponding narrow specialization (in relation to specialized machines) or an insufficient range (in relation to multifunctional machines) of the actual methods and means for their implementation, the frequency ("duty cycle") and seasonality of operation associated with such limited intended use. In particular, in a snowy winter at temperatures below 0 ° C, watering machines are not used as such for obvious reasons. For watering roadside vegetation - even more so.

The closest analogue (prototype) to the claimed invention in terms of purpose and set of features-operations is [9. RU 101459U1, Е01Н 6/00, 20.01.2011 "Device for removing snow and ice formations from road surfaces"].

At the same time, initially cold water is heated by an on-board heater using the heat of exhaust gases and a liquid working fluid of the ICE cooling system of a technological machine, and the pressure of the outlet jet is provided by an on-board water pump. In addition, melt water is collected by a water collector also directly under the technological machine and is used along with the primary supply of cold water in the onboard tank, with a passage through a filter.

In the prototype method, it should be noted, there is no direct description of the process of cleaning parked cars in the formation-array "in a snowdrift". A jet (s) of hot water is directed directly under the technological vehicle in order to melt snow and ice on the road surface in general. But it is clear that, with slow movement, and even more so with a temporary stop directly next to the clearing object, hot (more precisely, already warm) water, penetrating (flooding) and under such cars, will lead to gradual melting of snow and / or ice with subsidence " snowdrift ".

With this method, the following disadvantages occur:

- despite the high temperature of the water (after its forced onboard heating), "underflooding" from the bottom of such an object as a car "in a snowdrift" is very inefficient in terms of duration, water consumption and energy consumption, not to mention the dissemination of dirt and debris;

- to the massif - "snowdrift" water will come after mixing with the melt water of the roadway, that is, noticeably with a lower temperature;

- heating water only by an onboard motor unit significantly limits technical and operational capabilities;

- low productivity, which determines the duration of the operation, in turn determines the protracted nature of the "technological" narrowing of the carriageway, increased accident rate in terms of the probability of an accident.

The task (problem) to be solved by the claimed invention is to improve the efficiency of clearing snow, ice, mud and debris (leaves, etc.) from parked cars, productivity and safety of these works.

The technical result in accordance with the task is achieved due to the fact that in the method of clearing snow-covered and / or icy parked cars, in which a car or a group of cars is freed from an array of snow and / or ice with mud and debris, from the side of the roadway, by draining from a technological vehicle to the surface of the road surface with heated water by a jet or jets from an onboard container under pressure at the outlet of a water cannon, followed by disposal of at least melt water, according to the claimed invention, water is supplied under pressure by a jet at a temperature above zero degrees Celsius and under pressure above atmospheric, directly onto the said array with a car or a group of cars.

The technical result is also achieved due to additional sets of features (with the main set of features formulated above) of the method:

- they can use hot water, first taking it into the onboard tank from the housing and communal hot water supply network (this will additionally and very significantly enhance the technical result, since the intensity of snow melting increases sharply with increasing temperature);

- clearing can be carried out with at least one open nearest hatch of the communal drainage system (this avoids flooding of the clearing area and the surrounding area, which in itself is an "emergency" and in low air temperatures is fraught with ice on the corresponding sections of the roadway);

- the water formed as a result of the forced, by this method, the transition to the liquid phase can be pumped, by means of a pump based on the same technological vehicle, into the vacated mentioned onboard tank, with filtration from mud fragments at the inlet of the intake main (this, in contrast to actions according to the previous paragraph, solves the problem of prompt removal of melt water not by "gravity", which requires the appropriate topography of the road and a "low" level of the entrance to the hatch, but in any situation and in an accelerated mode);

- with the last sign, the melt water taken into the on-board tank can be drained in another specified place (this additionally expands the possibilities of the method, especially when there is no hatch nearby or its clearing and opening is problematic);

- at the penultimate sign, the melt water taken into the onboard tank can be used again to clean parked cars, releasing it to them through the injection line (this saves resources and time, increases work productivity);

- the water in the onboard tank can be additionally heated by onboard means (this additionally increases the clearing efficiency, especially in severe frost, when the water supply in the tank of the technological machine quickly cools down);

- with the latter sign, the exhaust gases of the onboard internal combustion engine can be used as the main or auxiliary means of additional heating of water in the onboard tank (this rationalizes the energy consumption for the operation).

Obviously, all actions (operations) are performed by material means over material objects.

To implement the method, no new or industrially feasible means (devices, material objects) are required.

Among the known methods, no ones have been found, the set of essential features of which would coincide with the declared one. At the same time, it is due to the latter that a new technical result is achieved, which determines the presence in the claimed method of the qualification feature “world level of novelty”.

This convincingly demonstrates the obvious originality ("super-effect"), ultimately - the inventive level of development as the second of the triad of qualification features of the invention.

The third qualification feature - "industrial applicability" - is obvious from the further description of an example of implementation of a technical proposal.

The description of the proposed method and device for its implementation is based on illustrations (drawings):

in fig. 1 shows a diagram of the method, front view, where the numbers indicate:

1 - car - object of clearing; 4 - snow and / or ice with mud and debris in the general case, an array (snowdrift, drift); 5 - carriageway; 6 - water jet; 7 - water jet; 8 - onboard water tank; 9 - technological vehicle used for clearing;

in fig. 2 shows a diagram of the implementation of the method, top view (in plan), where additional positions are designated:

1, 2, 3 - a group of cars in a common "skid" array to be cleared; 10 - hatch (closest to the vehicle being cleared) of the drainage system on the highway (sewer hatch);

Here we are talking, first of all and mainly, about groups (see Fig. 2) heavily snow-covered (in snowdrifts above the roof - see Fig. 1) cars that have long been parked along city highways in a state of disrepair, with a view to their subsequent removal by a tow truck, expanding the cleared roadway and restoring order in general.

The inventive method for clearing snow-covered and / or icy parked cars consists in the following operations.

One car 1 (see Fig. 1) or a group of cars 1, 2, 3 (see Fig. 2) is freed from an array of 4 snow and / or ice with inclusions of dirt and debris (most often in urban conditions and in the general case) from the side of the roadway 5, by removing the array 4 directly (direct fire, taking into account the ballistic trajectory, with hit within the midsection of the array 4) with a stream of water 6 at its temperature above zero degrees Celsius (90 ° C) and under pressure above atmospheric. In this case, a mobile water cannon 7 is used with an injection line (due to gravity with a difference in levels and / or an injection pump) and an onboard water tank 8 based on a technological vehicle 9. The latter can be either based on existing irrigation machines (cars or tractors), fire engines with cannons, police (Russian Guard) cars with water cannons to disperse demonstrators, or specialized, and, of course, a device according to the description of the prototype invention, with appropriate upgrades, including the implementation of the nozzle tip of the drain line with an adjustable angle of attack to its positive values.

Can (and is recommended) use hot water (of course, in a temperature range that is safe for people and animals around), first taking it into the onboard tank 8 of the technological vehicle from the housing and communal hot water supply network.

Can (and it is recommended) to carry out clearing with at least one open nearest hatch 10 (see Fig. 2) of the communal drainage system (of course, with the subsequent closing of the hatch 10 with a lid).

The water formed as a result of the forced, in this way, the transition to the liquid phase can (and is recommended) be pumped, by means of a pump based on the same vehicle 9, into the vacated side tank 8, with filtration from dirt fragments at the inlet of the intake line 9 (of course , unlike the prototype, here the water intake should be carried out not under the technological vehicle 9, but in the zone of the massif 4 (under it or down the slope).

In this case, the melt water taken into the onboard tank 8 can either be drained in another specified (authorized) place, or used again for clearing parked cars, releasing it to them through the discharge line.

The water in the onboard tank 8 can (and is recommended, especially at low air temperatures) be additionally heated by onboard means (as in the prototype, but with the difference that now it will not be the only, but additional (secondary) heating.

In this case, the exhaust gases of the onboard internal combustion engine (meaning the engine of this vehicle 9) can (and is recommended) be used as an auxiliary means of additional heating of water in the onboard tank.

The inventive method is, as a rule, an additional accompanying technical measure in the process of clearing roads (mainly urban) from snow, ice, mud, debris and ownerless vehicles.

The use of the invention allows, without long painstaking work and safely for people, animals and materiel around, to clear heavily snow-covered parked single cars and groups of cars, for example, for their subsequent evacuation to a special parking lot. At the same time, efficiency, productivity, resource conservation (water, energy), safety, traffic capacity and sanitary condition on highways increase, effective education of negligent car owners is carried out, etc.

It is important to note that the technical means for implementing the proposed method are not highly specialized and seasonal, since in their free time from the described operations (including in summer) they can be used as the same known machines for watering the roadway and shoulders (vegetation, pillars, fences, billboards and other structures sunbathing on the lawns of citizens), extinguishing small fires (garbage cans) and other household needs.

On the other hand, the expansion of the demand for watering machines (i.e. the possibility of their all-season use as such) should also be attributed to a positive organizational and technical result.

Of no small importance is the concomitant assistance to the common perennial problem of snow removal (utilization) in settlements.
