Description

The invention relates to vehicles maintenance techniques, in particular to automatic installations for external car washing.

The objective of the invention is to reduce the mechanical effects of automatic washing on the coating of the car.

The technical result is a decrease in the total capacity of the pumping unit, thereby reducing the total power consumption and ensuring a resource-saving mode (water and detergents). This is achieved by using a limited number of nozzles for pressure washing with controlled movement. The inventive working body contains a drive carriage having the ability to return movement along the working body, which is located on the rails. The carriage is equipped with a moving device. The latter (device) can be performed using guides, rails or gutters.

Known working body of a device for washing cars, containing rotary drive brushes mounted on consoles (http://www.christ-russland.ru/avtomoyki/portalnye/, for example Christ C160 Genius). The use of different brush design working bodies does not reduce and does not completely eliminate the inertial forces of the impact of the bristle threads on the car coatings, as well as the abrasive particles remaining on the brush, which leads to loss of gloss and further to the formation of scratches on the surface of the car body, and the exclusion of bristle carrier mobility in axial and angular directions reduces the activity of the brush at the point of contact with the contaminated surface of the car body, which eliminates the complete destruction of the film of contaminants, contributes to CB wear and loss elastic members brushes.

The closest in technical essence and the achieved result to the invention is the working body of the device for washing cars, containing nozzles for washing under pressure, located along the working body at a distance that allows you to get a continuous front of the jet at the required distance from the working body (http: // machine tools China. Russian Federation / beskontaktnaya-moyka1, FET-TR1014 or http://www.christ-russland.ru/avtomoyki/beskontaktnye/, Contactless portal car wash Christ С166 Aquatus). In this case, the nozzles can work simultaneously or turn on if there is a sprayed surface in the spray area. The installation of sinks with such working bodies requires a large power of the water pump or a decrease in the power of the jet, which leads either to large expenditures of consumed power or to a decrease in the quality of washing.

Conventional contactless sinks use a continuous jet front, the movement of which ensures a continuous surface treatment. In the closest analogue, fewer nozzles are used, and to achieve a continuous machining front, the nozzles are rotated cyclically, which in a static position do not provide a continuous jet front. In this case, the closest analogue does not prevent the ejection of the jet past the surface and does not provide a decrease in pump power.

Comparative analysis with the prototype Christ C166 Aquatus (http://www.christ-russland.ru/avtomoyki/beskontaktnye/christ-C 166-aquatus.html) allows us to conclude that the inventive working body of the device is different in that fewer nozzles are used while maintaining the ability to process a similar surface.

The proposed constructive solution of the working body for washing cars allows you to set the parameters of the jet (the working front of the jet, its shape and fluid speed), depending on the pump used, namely:

- by making appropriate movements, which are made depending on various kinds of contaminants and different profiles of the treated surface, and also taking into account the shape of the jet, the optimum use of the jet occurs;

- by adjusting the amplitude and frequency of the cyclic return movement of the carriage with nozzles and the working body along the surface, taking into account the speed of the liquid and the shape of the front of the jet, the optimal use of the characteristics of the jet occurs.

The practice of external non-contact washing of cars has shown that when using a powerful jet, its efficiency increases in the zone of contact between the jet and the car body, which contributes to a more effective destruction of the bonds of the adhesive contaminating film with the body due to the large energy of the water in the jet and the absence of abrasive effects on the surface, which manifests itself in high-quality washing and reducing mechanical stress on the treated surface. In the constructive solution of the working body for washing Christ C166 Aquatus cars using a jet of the same power, it is necessary to simultaneously use a large number of nozzles with a powerful jet, which increases the pump power, instantaneous flow of water and electricity, and also requires significant speeds of moving the working bodies along the surface to be treated. The use of a low-power jet reduces the efficiency of the installation when performing a technological cleaning operation — the destruction and removal of contaminants from the surface when washing cars. With an increase in the speed of movement of the working bodies along the machined surface, more efficient positioning of the consoles is necessary. In addition, if all nozzles are used simultaneously on the working tool, water is ejected past the surface to be treated, while the use of the required number of nozzles (turning off and on nozzles depending on whether the jet hits the surface to be treated or not) requires the use of a more complex pumping unit (flow control, overpressure relief, cascading of pumps of lower power). All this is a significant disadvantage of the prototype, which eliminates the claimed invention.

The claimed invention provides: the movement of the carriage with nozzles in accordance with the task of the control program (for controlling the washing of a computer), or a control mechanism (analog control) on the work surface; necessary jet power; reducing the power of the pumping unit by using a limited number of movable nozzles, as well as preventing the ejection of a jet past the surface being treated and the efficient use of liquid energy for cleaning, and thus improving the quality of washing the surface of the car body as a whole.

The solution to this problem is achieved by the fact that the working body of the device for washing cars contains a movable carriage with controlled movement, a limited number of nozzles for washing are located on the carriage. Also, nozzles for applying detergents, surface care products, various sensors and sensors can be located on the carriage. In this case, the movement of the carriage depends on the technological cycle: washing under pressure, applying detergent, determining the parameters of the surface to be treated, depending on which one or another nozzle or sensor is used. In the case of washing under pressure, this is the return movement of the carriage with the simultaneous mutual movement of the working body and the work surface. One component of the movement is achieved by moving the carriage along the working body, another component of the movement is achieved due to the mutual movement of the working body and the work surface.

The figure 1 shows an example of the machined surface 1 and the trajectory of the center of the jet 2 along the machined surface of the car.

The figure 2 shows an example of a General view of the working body: 3 - controlled drive; 4 - moving device; 5 - guides; 6 - carriage; 7 - working body; 8 - nozzles for washing; 9 - detergent nozzle; 10 - nozzle care products; 11 - sensor shape and size of the processed surface; 12 - sensor to prevent collision of the worker with the treated surface.

An example of the practical implementation of the invention

The working body 7 of the car wash device contains a movable carriage 6 with controlled movement, on which there are two nozzles 8 for washing under pressure, one nozzle 9 for applying detergent and one nozzle 10 for means for cleaning the surface, on the working body 7 are installed a sensor of the size and shape of the treated surface 11 and the sensor 12, which performs the function of eliminating the collision of the working body with the treated surface. In this case, the movement of the carriage 6 determines the technological cycle “washing under pressure, applying detergent and determining the dimensions of the surface to be treated”. In accordance with it, for example, nozzles 9 and 10, a detergent nozzle 9 and a size sensor of the work surface 11 are used. At the stage of the “pressure washing” process cycle, the carriage 6 moves back along with the working body 7 moving along the work surface, and the operation of the nozzles 8. This is similar to the operation of an inkjet flatbed plotter, drawing the profile of the car, and is essentially a new use, which also confirms the novelty of the present invention.

In general, all this improves the quality of car washing and expands the technological capabilities of the claimed device.
