 Installation for car washing

Technical field

The utility model relates to equipment for washing with a high pressure jet of contaminated surfaces and can be used for hydrotreating and washing vehicles.

State of the art

A patent of Russia for utility model JNS 1 19307, published on 09/26/2011 1, is known. The car wash installation contains a supporting frame for attaching a guide and a console, a supporting suspension unit comprising a supporting distribution block structurally consisting of several cylinders connected to a metal frame with each other with the possibility of rotation relative to the central common axis by means of ball bearings, and having inputs and outputs for separate supply of washer fluid and chemicals to the system from the ear of the L-shaped pipelines by means of high-pressure hoses, as well as a console with roller brackets for the possibility of moving the system from two L-shaped pipelines from rigidly interconnected pipes of various diameters with nozzles located at different angles, while the support rollers are rigidly fixed to the pipelines moving along an ellipsoidal guide, rotate 360 °, and a system of two L-shaped pipelines with nozzles, rotating around a car along a constant ellipsoidal path, feeds for a given algorithm at a vehicle surface washer fluid and pressurized chemicals in the automatic mode,

This model is limited by the size of the constant ellipsoidal path along which two L-shaped pipelines move, i.e. if the machine has a larger size, then washing it with such an installation will not work. The claimed installation is uneconomical in time and not effective enough. The closest analogue, chosen as a prototype, is the “Contactless automatic car wash“ Typhoon ”, published on the Internet on June 29, 2016 at www.gpa.ru, manufactured by Gatchina Prom-Avtomatika. Sink "TYPHOON" works according to the following principle. The washing cycle is carried out by one movable bar (one load-bearing module in the form of a beam for fastening one L-shaped pipe) along the perimeter of the car with the supply of high pressure water, applying detergents and polishing agents. A set of sensors is installed on the bar to determine the overall dimensions of the vehicle. The final stage of the cycle is the drying of the car. It is carried out by a drying beam with an adjustable speed of movement, on which three fans are installed (power of one is 4 kW, productivity is 5000 m1 / min).

They control the washing process from the control panel, which includes: an integrated PLC, frequency converters, cables and cable channels, a touch control panel with signal lamps and buttons for selecting the specified washing programs, as well as control of individual blocks of the washing complex.

The availability of developed programs to support the washing process, control of the water treatment unit and the circulating water treatment unit. Washing programs are customized based on customer requirements and the chemical composition of the water. The car wash time is from 5 to 15 minutes.

The disadvantages of this washing are the insufficient speed and efficiency of washing the car.

The technical task of the proposed utility model is the creation of a non-contact automatic installation for washing cars with high speed and efficiency. The technical result of the claimed technical solution consists in a consistently high quality of washing without mechanical impact on the paintwork surface and reducing the time for hydrotreating.

The specified technical result is achieved by the fact that the car wash installation comprises a control panel, which includes: a built-in programmable logic PLC controller, frequency converters, cables and cable channels, a touch control panel with signal lamps and buttons for selecting the specified washing programs, as well as control of individual blocks of the washing complex, at least one carrier module in the form of a beam for mounting at least one L-shaped pipe with nozzles and side sensors and to determine the overall dimensions of the car, according to the utility model, the installation contains two modules on each of which two L-shaped pipelines with nozzles and side sensors are installed to determine the overall dimensions of the car, and in the middle of each module there is a reference distance sensor and two devices one for each L-shaped pipeline connected by cables to the control panel and giving a command to move the L-shaped pipelines and modules in the opposite direction.

Due to the fact that the installation contains two modules on each of which two L-shaped pipelines with nozzles and side sensors are installed to determine the overall dimensions of the car, and in the middle of each module there is a reference distance sensor and two devices, one for each L-shaped the pipeline connected by cables to the control panel and giving the command to move the L-shaped pipelines and modules in the opposite direction increases in the quality of the wash without mechanical impact on the paintwork surface and bottom time for hydrotreating takes place.

The inventive installation for car washing has a novelty, differing from the prototype of the above features, and ensures the achievement of the result perceived by the applicant.

The inventive installation for car washing can be widely used for washing with a high pressure jet of contaminated surfaces and 2017/000845

Brief Description of the Drawings

The essence of the proposed utility model is illustrated by drawings, which show:

- figure 1 is a General view of the installation for washing cars, axonometry;

- figure 2 is a General view of the module with two L-shaped pipelines, axonometry;

- in FIG. 3 - general view of the L-shaped pipeline with duct, axonometry.

The proposed installation for car washing contains a control panel 1, which includes: built-in programmable logic controller 2 (PLC), frequency converters, cables and cable channels, touch control panel with signal lamps and buttons for selecting the specified washing programs, as well as control of individual blocks of the washing complex (in Fig. positions are not shown). It contains supporting longitudinal metal guides 3, suspended from the ceiling or mounted on the wall or installed in the floor, along which two modules 4 back and forth move by a signal from the control panel 1. Moving the modules 4 back and forth is carried out by means of servomotors 5 (in the embodiment) connected by a cable (not shown in FIG. 1) to the control panel 1. These servomotors 5 have the ability to set the desired rotation speed, have a very accurate fixed pitch (which allows them to move in space with millimeter precision during operation), and some of them have the ability to set their own internal program, which will start at the right time. Modules 4 are made with supporting transverse metal guides 6 for moving by signal from the control panel 1 of the metal boxes 7 inside the modules 4, two metal boxes 7 per module 4.

Inside each box 7, the following mechanisms are installed. Servomotor 8 for moving the box 7 along the transverse metal guides 6. Swing mechanisms 9 with a rotary console 10 bearing T RU2017 / 000845

5 suspensions 11. Each bearing suspension 11 contains washing elements — a system of L-shaped pipelines 12 with nozzles 13. Pipelines 12 consist of pipes of various diameters rigidly interconnected with nozzles 13 located at different angles. The rotation mechanisms 9 are rotated according to the signal from the control panel 1, the suspension bearings 11 together with the system of L-shaped pipelines 12 with nozzles 13.

 Also, the car wash installation contains distribution blocks 14, which are located in the technological room together with the standard car wash equipment used (not shown in Fig.) And are associated with each washing element. On each module 4, there is a sensor 15 of the reference distance, in which a value equal to the distance from the sensor to the floor is considered as a reference. In addition, lateral sensors 16 are located on the L-shaped pipelines 12 so that the pipelines 12 of the washing elements remain at a safe distance from the car so as not to come into contact with the protruding elements of the body (side mirrors, antennas, outer covers of the spare wheel for SUVs, kengurin). In the middle of each module 4 there are two devices connected by cables (not shown in Fig.) With the control panel 1 and giving the command to the L-shaped pipelines 12 and modules 4 in the opposite direction - the limit switch 17.

Installation for car washing works as follows.

The work of the entire car wash installation is carried out according to the originally laid down program. For the execution of the program meets the programmable logic controller 2 in the control panel 1.

 The executive system consists of two modules 4, on each of which there are two washing elements - L-shaped pipelines 12 with nozzles 13. Before starting the program, modules 4 are located next to each other at such a point that the car that entered the car wash after stopping is below them in the middle.

On each module 4, there is a sensor 15 of the reference distance, in which a value equal to the distance from the sensor to the floor is considered as a reference. The distance sensors 15 are not located on the modules 4 themselves, but will be slightly taken out of their borders. When the car falls under this sensor 15, the value changes (becomes smaller). A step-by-step program starts.

 In the first step, the cleaning elements of all four L-shaped pipelines 12 begin to approach the vehicle until the lateral sensors 16 on the L-shaped pipelines 12 fix a distance of 40 cm-100 cm from it, in case the car is not located smoothly. To achieve the best car wash results, the optimal distance from the cleaning elements to the car is selected. In order for the jet from nozzles 13 to cover the entire surface, it was powerful enough to remove strong impurities and at the same time the washing elements remained at a safe distance from the car so as not to come into contact with the protruding elements of the body (side mirrors, antennas, outer spare tire covers for SUVs , kengurin). A servomotor 8 is operating, moving metal boxes 7 with washing elements along the transverse metal guides 6.

 In the second step, the first water supply cycle is started, the servomotors 5 begin to work, and the modules begin to move from each other along the longitudinal metal guides 3 until the reference distance sensor 15 again registers the reference value (washing elements will extend beyond the vehicle’s dimensions).

 In the third step, when the reference value is read and satisfies all the conditions described above in step 2, a command is issued to rotate the washing elements 90 degrees. The rotation mechanisms 9 rotate the washing elements of the L-shaped pipelines 12.

 In the fourth step, after the rotation, the washing elements begin to approach each other until each of them reaches the middle of module 4, i.e. at some point, the cleaning elements should be next to each other. In the middle of each module 4 there are two limit switch devices connected by cables (not shown in FIG.) To the control panel 1 and giving the command to the L-shaped pipelines 12 and modules 4 in the opposite direction.

 After completing the fourth step, everything is repeated in reverse order, until the washing elements and modules 4 are in the position corresponding to the first step.

Then a command is given to supply the next fluid and the steps are repeated. A full wash cycle will look like this:

 - Launch the program;

 - Rapprochement of the washing elements;

 - Water supply, execution Step 1 - Step 2 - Step 3 - Step 4 - Step 3 -Step 2 - Step 1;

 - cessation of water supply;

 - Foam supply, execution Step 1 - Step 2 - Step 3 - Step 4;

 - cessation of foam;

 - Water supply, execution Step 4 - Step 3 - Step 2 - Step 1;

 - cessation of water supply;

 - Wax supply, execution Step 1 - Step 2 - Step 3 - Step 4;

 - Cessation of wax supply;

 - Water supply, execution Step 4- Step 3 - Step 2 - Step 1 - Step 2 - Step 3- Step 4;

 - cessation of water supply;

 - Drying, execution Step 4 - Step 3 - Step 2 - Step 1;

 - Stopping the drying, the return of the cleaning elements to their original position;

- Completion of the program.

 To achieve a better car wash result, the first and last water supply cycles should be longer than the foam and wax supply cycles. Therefore, water supply cycles are assumed when performing steps 1-2-3-4-3-2-1, while supplying the remaining fluids involves only steps 1-2-3-4, or 4-3-2-1.

Thanks to repeated surface treatment, quality and, consequently, high hydrotreatment efficiency is achieved.

As a result of the design of the washing according to the above proposed technical solution, a technical problem is solved - the creation of a non-contact automatic installation for washing cars with high efficiency.

Thus, the implementation of the device using a system of L-shaped pipelines 12 rotating around a car with nozzles 13, which supplies washer fluid and chemicals under pressure, without the use of human labor, allows one to achieve high the effectiveness and quality of the washing process without mechanical impact on the paintwork.

To move the modules 4 and boxes 7 inside them, it is supposed to use servo motors 8 SPSh 5. The features of this servo drive are:

 - implemented control modes of the angular position, speed, moment;

- in the basic firmware is available the mode of smooth acceleration / deceleration with

 the exclusion of two ranges of resonant frequencies;

 - positioning accuracy from 6 arc minutes to 8 arc seconds;

 - built-in programmable logic controller giving

 the user the ability to create drive movement programs without using external controllers;

 - a synchronization mode of a group of drives is possible (up to 128 drives based on an industrial CAN bus);

 - “master-slave” operating mode is implemented

 - the presence of the Step / Dir interface for setting the position of the motor shaft;

 - analog ± 10 V interface for setting the engine speed;

 - the control unit has 2 digital outputs, 4 electrically isolated

 digital input;

 - the drive has built-in protection against short circuit, overheating,

 over and under voltage;

 - tuning of the control system of the SPS can be carried out according to more than 50 parameters, which allows to optimize the operating characteristics of the drive to solve each specific problem;

 - the oscilloscope mode is implemented in the servo drive, which allows analyzing the quality of transient processes in the drive with high resolution.

 Also specially designed for these engines are power supplies BShO-23 / BP10-34 and BP30
