DEFECTIVE PROTECTION SYSTEM AND DEFINITION SYSTEM WITH EQUIPMENT {DISINFECTANT SCATTERING APPARATUS AND DISINFECTANT SCATTERING SYSTEM USING IT}

The present invention relates to a quarantine device and a quarantine system having the same, and more particularly, can effectively perform a quarantine operation without limiting the size of the vehicle to enter, can effectively prevent a person or animal as well as the vehicle The present invention relates to a quarantine system capable of automatically quarantine while minimizing the number of quarantine personnel and a quarantine system having the same.

In general, when various livestock epidemics occur, appropriate countermeasures are established and implemented.

For example, when a highly infectious disease such as foot-and-mouth disease is outbreak, access control and quarantine work around it is performed. The quarantine work mainly involves disinfecting the place where the disease occurs or disinfecting a vehicle passing through the area.

As such a prevention technology, a vehicle protection system disclosed in Korean Patent Publication No. 10-1049157 has been proposed.

As shown in FIG. 1, the anti-fouling system includes a drug tank 1, a pump 2 connected to the drug tank 1, a plurality of injection nozzles 5 for injecting drugs, and the pump 2. ) And a drug distribution pipe (4) and a drug distribution pipe (4) connecting the injection nozzle (5).

In addition, an air pipe 7 is inclined with respect to the drug advancing direction to the drug pipe 6, and an air compressor 3 is installed in the air pipe 7.

When the vehicle is detected by a sensor (not shown) installed in advance on the floor and the like by accessing the vehicle defense system, the opening and closing valve 8 connected to the pump 2 is connected to the pump 2 at the same time. The drug 1 is opened and injected into the vehicle through the drug pipe 6, the distribution pipe 4, and the injection nozzle 5.

The above-described conventional defense system can be disinfected by spraying the drug at the time of entering the vehicle, but there are limitations with the following problems.

First, since the distribution pipe 4 disposed on both sides has a fixed structure, the conventional vehicle defense system has a problem that cannot be used when the vehicle to be entered is too large in width.

In addition, the conventional vehicle defense system has a disadvantage in that the actual defense operation is impossible because the entry vehicle is small in width or when a two-wheeled vehicle such as a motorcycle enters, no drug is applied or an appropriate amount cannot be injected.

In order to solve this problem, a method of increasing the injection pressure injected into the injection nozzle 5 may be attempted, but if the injection pressure is increased, the amount of injection of the drug is increased, which leads to a high waste, and thus the cost of the prevention of pesticide is increased.

In addition, the conventional vehicle defense system can perform the vehicle quarantine to some extent, but there is a disadvantage in that it is inconvenient to carry out the prevention of humans or animals.
