Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for preventing pathogens from being brought into vehicles such as dairy farms, livestock farms, food processing factories, etc., which enter and exit facilities requiring epidemics.

[0002]

2. Description of the Related Art In recent years, the scale of livestock farming has increased the damage when livestock infectious diseases occur, and the import volume of meat has increased and the import destinations have been diversified.
There are more opportunities for infectious diseases not found in Japan. Under these circumstances, one of the causes of the spread of these infectious diseases may be that soil contaminated with bacteria is attached to vehicle tires and passenger shoes and brought to dairy farms, livestock farmers, etc. I have. In addition, it is not limited to livestock infectious diseases.
As for pathogens that cause serious damage when infected with humans, such as -157 etc., the contaminated soil is carried to the food processing factory by the wind, whereby the processed food may be contaminated and transmitted to humans. It has also been reported.

[0003] Conventionally, in dairy farms, livestock farms, food processing factories, etc., the use of a spray washer has been used to remove bacteria from tires of vehicles entering and exiting and shoes of passengers.

[0004]

However, according to recent investigations and experimental results described later, although a sufficient effect on disinfection has been obtained by the disinfectant washing water for disinfection, Cannot be completely sterilized,
It turned out that it was not a sufficient measure depending on the method of eradication. Specifically, if bacteria are removed in the immediate vicinity of a facility that requires disinfection, bacteria that have been washed down and have not died will re-attach to the soles of employees of that facility, It has been found that infectious diseases can be transmitted to livestock, or that they can be carried into food factories by wind and contaminate processed foods.

SUMMARY OF THE INVENTION The present invention has been made to solve such a problem, and the bacteria washed down from a vehicle or the like entering or exiting the facility by the washing water of the disinfecting apparatus can be removed from the soles of employees or the like of the facility. Re-attached to the animal, infecting livestock with infectious diseases,
Another object of the present invention is to provide a method for preventing pathogenic bacteria from being introduced into a vehicle or the like so that the processed food is not contaminated by wind.

[0006]

In order to solve the above-mentioned problems, a means adopted by the present invention is to disinfect a vehicle tire using cleaning water for disinfecting at a disinfecting place remote from a facility requiring epidemics. Alternatively, it is to carry out the disinfection cleaning of the occupant's shoes. Even if it is a place away from the facility, a place where the pathogens washed down by the wash water may be carried into the facility by wind,
It cannot be a sanitizing place.

[0007] A sufficient amount of washing water is required to prevent the bacteria washed off by the washing water from re-adhering to the soles of employees of the facility or the like. Bacterial washing includes a tank that stores washing water for disinfection, a pump that is driven by an electric motor to pump the washing water in the tank, and a switch that is operable from the driver's seat and controls the operation of the pump. A tire injection nozzle disposed on the tire housing for injecting purified water pumped by a pump to the tire, and a passenger injection nozzle for injecting cleaning water pumped by the pump to occupant shoes outside the vehicle. The disinfection is carried out by a disinfecting device provided on a vehicle equipped with: This disinfecting apparatus can remove bacteria from the driver's seat, can disinfect tires evenly with a sufficient amount of fluid, can disinfect shoes and the like of occupants getting on and off this vehicle, and can be used in any vehicle having a battery. It can be mounted on any vehicle.

For example, a plurality of tire injection nozzles are provided in the tire housing in the machine width direction so as to be able to inject washing water to the peripheral surface and side surfaces of the tire. Use a hand-operable one connected to a pump via an on-off valve.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The method of the present invention will be described with reference to the process chart shown in FIG. As a first step, when a vehicle enters a facility such as a dairy farm, a livestock farm, or a food processing plant that requires epidemics, a vehicle is used as a sterilization place at a location away from these facilities. It is important that this disinfecting place is not only a place away from the facility but also a place where the pathogens washed down by the washing water are not likely to be carried into the facility by wind. In addition, it is naturally necessary that the pathogen is a place where the dropped pathogens are not likely to be attached to shoes of employees and the like coming and going and being brought into the facility.

In the second and third steps, the tires of the vehicle, the shoes of the occupants, and, if necessary, the clothes are sterilized and washed at the sanitizing place thus determined. However, disinfection and cleaning of the occupant's shoes etc. shall be carried out as necessary. After the cleaning of the tires of the vehicle and the shoes of the occupants is performed, the vehicle is made to enter a destination in the facility as a final fourth step.

[0011] The germicidal washing in the second and third steps described above includes:
A tank for storing cleaning water for disinfection, a pump driven by an electric motor to pump the cleaning water in the tank, a switch operable from the driver's seat to control the operation of the pump, and a tire housing. A tire injection nozzle for arranging and injecting purified water pumped by a pump to a tire, and an occupant injection nozzle for injecting washing water pumped by a pump to occupant shoes and the like outside the vehicle. This is performed by a disinfection device installed in the vehicle.

Next, the germicidal effect of the method of the present invention will be described based on an experiment conducted by Obihiro University of Agriculture and Veterinary Sciences. (Experimental method) Pacoma solution (trade name) was sprayed from the tank mounted on the truck onto the surface of the tire, and the number of general bacteria in the solution containing soil that had flowed out was examined. The concentration of pacoma is 100
The test was performed in two stages of 1-fold and 500-fold dilution. (Experimental results) Sterilization effect of general bacteria in soil adhered to tire surface by Pacoma solution (treatment area) (Number of general bacteria) Water 1.7 × 10 6 Pacoma diluted 500 times 3.7 × 10 2 Pacoma 100 times diluted 1. The numbers in the table are bacteria in 1 g of the washing solution.

The results of this experiment show that the number of general bacteria present in the soil on the tire surface is reduced to about 1 / 5,000 by the disinfectant 500-fold dilution, and to about 1 / 10,000 by the 100-fold dilution.
Therefore, it is considered that the eradication washing according to the method of the present invention can prevent contamination by pathogenic bacteria at a considerable level beforehand. However, some bacteria survive after spillage, not complete sterilization.Therefore, eradication and washing should be performed in a place away from facilities that require quarantine prevention and in a place where the spilled surviving bacteria are not brought in by the wind. Suggests what should be done.

As described above, the tires of the vehicle and the shoes of the occupants can be stored at a place away from the facilities requiring epidemics, and
The bacteria that have been washed away by the washing water of the disinfecting equipment are removed by removing bacteria at a place where there is no possibility that the pathogens washed down by the washing water will be carried into the facility by the wind. The likelihood of infecting livestock with infectious diseases by reattaching to the soles of the animals or contaminating processed foods is extremely low.

[0015] Also, when leaving the facility, it is desirable that the tires of the vehicle and the occupants' shoes and the like be similarly sterilized at the above-mentioned location.

[0016]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the method of the present invention will be described with reference to FIGS. 2 and 3 show a small or medium-sized truck having two front wheels and four rear wheels, to which a disinfection device for carrying out the method of the present invention is attached. As shown in FIGS. 2 and 3, a tank 2 for storing cleaning water for sterilization and a pump 3 driven by an electric motor to pump the cleaning water in the tank 2 are provided on the vehicle body 1.
For example, a switch 4 for controlling the operation of the pump 3 is provided on the operation panel of the driver's seat. The switch 4 is mounted so that the driver can operate the truck while driving. Switch 4 is connected to battery 6 of the vehicle.
A tire injection nozzle 9 for injecting the cleaning water pumped by the pump 3 to each tire 8 is attached to the tire housing 7. As shown in FIG. 3, the injection nozzle 9 allows the cleaning water to be injected from both sides of the tire 8,
Two are arranged in the machine width direction. Although the injection nozzle 9 is attached to the front of each tire 8 with the injection port facing rearward, the attachment position is not necessarily limited to the front of the tire 8.

A manual switching valve 10 having two outlets is disposed between the pump 3 and the injection nozzle 9. The inlet is connected to the pump 3, and one outlet is connected to the injection nozzle 9. Further, the other outlet of the switching valve 10 is provided with an occupant injection nozzle 11.
Attach. The injection nozzle 11 is connected to a hose 13 extending from the pump 3 via a switching valve 10 so that the washing water can be injected by a hand-held operation outside the vehicle. FIG.
As shown in FIG. 4, the injection nozzle 11 has an on-off valve 12 for washing water. In the case of a truck, the injection nozzle 11
It is equipped on the back of the driver's seat.

First, the tire 8 is sterilized by stopping or slowing down the vehicle, for example, by a driver from the driver's seat of a truck. The switching valve 10 communicates the pump 3 and the tire injection nozzle 9. The driver turns on the switch 4 attached to the operation panel in the driver's seat. The pump 3 is operated, and the germicidal washing water stored in the tank 2 is jetted from the jet nozzle 9. The washing water is sprayed on the peripheral surface and both side surfaces of each tire 8 that has stopped or is slowly rotating. The vehicle with double tires shown in FIG. 2 also has at least one radially opposite side face of the two tires 8.
It is desirable to spray about 0 cm. Such injection is possible by the two injection nozzles 9 provided in parallel in the machine width direction described above. In particular, when the vehicle is stopped to remove bacteria, it may not be possible to sufficiently remove the soil from the ground contact area of the tires. Cleaning may be performed. When it is determined that sufficient injection has been performed and the contaminated soil has been washed down from the tire 8, the switch 4 is turned off.

Next, germ-free cleaning of the occupant's shoes and the like is performed when the occupant gets off the vehicle. Therefore, when the tire 8 is disinfected and washed slowly, the vehicle is stopped. By operating the switching valve 10, the pump 3 and the injection nozzle 11 are communicated. The switch 4 on the operation panel of the driver's seat is turned on. The pump 3 operates to pressurize the washing water. The occupant holds the injection nozzle 11 provided at a predetermined position of the vehicle in his / her hand, and operates the on-off valve 1 thereof.
Operate the valve 2 to open the valve, and spray the washing water onto the shoes and, if necessary, the clothes to wash off the contaminated soil. In particular, it is important for the soles of the shoes to thoroughly remove the soil.
After the end, the switch 4 is turned off, and the switching valve 10 is switched to return the communication between the pump 3 and the injection nozzle 9.

According to this disinfecting apparatus, since the washing water is injected by operating the switch 4 provided on the driver's seat, the driver can disinfect and clean the entire tire 8 evenly while sitting on the driver's seat. Further, since the washing water stored in the tank 2 of the vehicle body 1 is used, it is possible to perform the disinfection washing with a sufficient amount of liquid.

[0021]

As described above in detail, the method of the present invention uses a disinfecting apparatus in a place away from a facility requiring quarantine measures and at a place where wind is unlikely to carry pathogens. Of the tires and occupants' shoes are cleaned using a sufficient amount of washing water, so that the pathogens that have been washed away by the washing water and have not been killed adhere to the shoe soles of employees of the facility. And infecting livestock with infectious diseases, or
It has an excellent effect that it does not invade by the wind and contaminate the processed food.
