Hereinafter, an operation process of the tire and wheel washing apparatus 1 of the present invention will be described with reference to FIGS. 1 to 10.

As shown in FIG. 2, when the vehicle A enters between the pair of guide bases 110 and 110a, the vehicle detection sensor 161 detects the entry of the vehicle A and transmits an entry signal to the control unit 300. . In this case, an entry lamp (not shown) may be provided on the side surfaces of the guide bases 110 and 110a so that the driver of the vehicle A can determine the entry position.

The manager sees the entered vehicle model and inputs the vehicle model into the input unit 170 as either small or large.

When the entry signal is transmitted to the controller 300, the controller 300 applies a driving signal so that the detergent pump 152 and the driving motor 141 rotate in the forward direction, and drives the first timer 163. The control unit 300 drives the driving motor 141 in the forward direction so that the nozzle frame 130 moves from the initial position P1 to the spray position P2 as shown in FIG. 8A. While the nozzle frame 130 moves from the initial position P1 to the spray position P2, the detergent nozzle 121 sprays the detergent D onto the tires and wheels B of the vehicle A.

The movement detection sensor 162 located at the injection position P2 detects the approach of the nozzle frame 130. When the movement detection sensor 162 detects the approach of the nozzle frame 130, it transmits a detection signal to the controller 300. When the detection signal of the movement detection sensor 162 is transmitted and the time of the first timer 163 is ended, the control unit 300 stops driving the driving motor 141 and the detergent pump 152.

In addition, the control unit 300 drives the driving motor 141 in the reverse direction and drives the foam pump 154. In addition, the second timer 164 is also driven for a set time. As a result, the nozzle frame 130 returns from the injection position P2 to the initial position P1, as shown in FIG. 8B, and the foam nozzle 123 is connected to the tire and wheel B of the vehicle A. Spray the foam (E) with ). Foam (E) adheres to the surfaces of tires and wheels (B) to dissolve contaminants.

The return detection sensor 162a senses that the nozzle frame 130 returns to the initial position and transmits a detection signal to the control unit 300, and when the time of the second timer 164 ends, the control unit 300 operates (141) and the drive of the foam pump 154 is stopped.

When the spraying of the detergent (D) and the foam (E) is completed in this way, the driver drives the vehicle A and moves to the washing water spray unit 200 in the front. As shown in FIG. 9, the driver moves so that the front wheel of the vehicle A is positioned on the washing water nozzle unit 220, the rotating nozzle 223 of the washing water nozzle unit 220 is rotated, and the washing water ( W) is supplied at high pressure to clean the foam (E) and contaminants applied to the wheels and tires of the front wheel.

When the washing of the front wheel is completed, the driver drives the vehicle A forward so that the rear wheel is positioned on the washing water nozzle unit 220 as shown in FIG. 10.

In addition, the rotating nozzle 223 of the washing water nozzle unit 220 is rotated and the washing water (W) is supplied to the rear wheel at high pressure to clean the foam (E) and contaminants applied to the wheels and tires of the rear wheel. This completes the cleaning process for the vehicle's tires and wheels.

As described above, the vehicle tire and wheel cleaning apparatus according to the present invention professionally cleans only the tire and the wheel, not the exterior surface of the vehicle. In particular, since detergents and foams capable of removing contaminants from tires and wheels are sprayed independently, and the process of washing them with washing water is sequentially performed, tires and wheels can be cleaned cleanly.

In addition, the vehicle tire and wheel washing apparatus has the advantage of minimizing the intervention of a worker by respective sensors and timers, and the washing operation can be performed automatically.

Meanwhile, an anti-corrosion coating layer may be applied to the rotating nozzle 223 to prevent corrosion of the metal surface. The coating material of this anticorrosion coating layer is benztriazole 15% by weight, ethylene glycol butyl ether 25% by weight, hafnium 20% by weight, molybdenum emulsified (MoS ² ) 10% by weight, titanium oxide (TiO ² ) 15% by weight, phenol It consists of 15% by weight of noblock-type glycidyl ether, and the coating thickness can be formed to 8㎛.

Benztriazole, ethylene glycol butyl ether, and phenol noblock glycidyl ether play a role in preventing corrosion and discoloration.

Hafnium is a transition metal element with corrosion resistance and plays a role in having excellent waterproof and corrosion resistance.

Molybdenum emulsified plays a role of imparting wetness and lubricity to the surface of the coating film.

Titanium oxide is added for the purpose of fire resistance and chemical stability.

The reason why the ratio of the constituent components and the coating thickness were numerically limited as described above is that the present inventors analyzed through the test results while repeatedly failing several times, and as a result, the optimum anti-corrosion effect was exhibited at the ratio.

In addition, a contamination prevention coating layer made of a contamination prevention coating composition may be applied to the outer surface of the vehicle detection sensor 161 so as to effectively prevent adhesion and removal of contaminants.

The anti-fouling coating composition contains mercaptobenzothiazole and amidoalkyl betaine in a molar ratio of 1:0.01 to 1:2, and the total content of mercaptobenzothiazole and amidoalkyl betaine is 1 with respect to the total aqueous solution. ~10% by weight.

The mercaptobenzothiazole and amidoalkyl betaine are preferably 1:0.01 to 1:2 as a molar ratio.If the molar ratio is out of the above range, the applicability of the vehicle detection sensor 161 decreases or the surface moisture There is a problem that the coating film is removed due to increased adsorption.

The mercaptobenzothiazole and amidoalkyl betaine are preferably 1 to 10% by weight in the total aqueous solution of the composition, and if it is less than 1% by weight, there is a problem that the applicability of the vehicle detection sensor 161 is deteriorated, and 10% by weight is If it is exceeded, crystal precipitation is likely to occur due to an increase in the coating film thickness.

On the other hand, as a method of applying the present contamination prevention coating composition on the vehicle detection sensor 161, it is preferable to apply it by a spray method. In addition, the thickness of the final coating film on the vehicle detection sensor 161 is preferably 550 to 2000 Å, more preferably 1100 to 1900 Å. When the thickness of the coating film is less than 550 Å, there is a problem of deterioration in the case of high-temperature heat treatment, and when it exceeds 2000 Å, crystal precipitation on the coated surface is liable to occur.

In addition, the present antifouling coating composition may be prepared by adding 0.1 mol of mercaptobenzothiazole and 0.05 mol of amidoalkyl betaine to 1000 ml of distilled water, followed by stirring.
