Description

DETAILED DESCRIPTION OF THE INVENTION (a) Industrial Application Field The present invention is used in the field of garbage collection vehicles that require cleaning and extinguishing the inside of a container containing garbage.

(b) Conventional technology Generally, a garbage collection vehicle has a structure in which a pushing device that can rotate upward is provided at the rear of the container, and after the collection work is completed, the pushing device is rotated upward to clean the inside of the container. There is.

However, in the above-mentioned cleaning work, the worker crawls under the pushing device and sprays cleaning water into the container from the rear of the container, so sewage may splash onto the worker or the pushing device may malfunction for some reason. There were problems such as falling and injuring workers. In addition, portable gas cylinders, etc. may be loaded during the loading process of garbage, and sparks generated by the friction of the garbage ignite the residual gas of the loaded portable gas cylinders, etc., igniting and exploding, causing a fire. However, since the container is sealed, if a fire breaks out inside, the fire must be extinguished after removing the garbage, which tends to delay the initial extinguishment, and some fires may be extinguished. In some cases, fire trucks were unable to extinguish the fire by spraying water on it.

(c) Problems to be solved by the invention The present invention solves the above-mentioned problems.
An injection pipe having a plurality of nozzles is provided in the upper part of the container, and water or fire extinguishing liquid is sprayed from the injection pipe to clean the inside of the container or extinguish the fire.

(d) Means for solving the problem The present invention includes a container for storing garbage mounted on the vehicle body,
In a garbage collection vehicle in which a pushing device that can rotate upwardly is connected to the rear of the container, an injection pipe having a plurality of nozzles is fixed to the top of both sides inside the container, a protective cover is provided along the injection pipe, and the container is This invention relates to a container cleaning and fire extinguishing system in a garbage collection vehicle which is connected to a pipe opened to the outside.

(e) Action When performing cleaning work, after rotating the pushing device upwards, connect the hose from the water supply to the pipe and open the on-off valve. Water is sprayed from the nozzle of the injection pipe to the inner surface of the container, causing water to flow inside the container. can be washed.

In the event of a fire, connect the hose from the water supply or the hose that carries fire extinguishing liquid to the pipe,
When the on-off valve is opened, water or fire extinguishing liquid is injected from the nozzle of the injection pipe onto the inner surface, making it possible to extinguish the fire.

(f) Embodiment Hereinafter, an embodiment will be explained with reference to the drawings. Reference numeral 1 denotes a container for storing garbage mounted on the vehicle body 2;
A discharge plate 3 is provided inside for discharging the stored garbage to the rear.

A pushing device 4 that can be rotated upward is connected to the rear of the container 1, and the pushing device 4 pushes the garbage thrown into the container 1 from the input port 5 at the rear of the pushing device 4.

6 is a cleaning and fire extinguishing device for cleaning and extinguishing the inside of the container 1, and the cleaning and fire extinguishing device 6 will be explained below.

Reference numerals 7, 7 denote a pair of injection pipes provided at the corners of both side walls 8, 8 and the ceiling 9. A plurality of nozzles 10... are formed in the injection pipes 7, 7, and the nozzles 10... are directed toward the inner surface. Formerly designed to spray water or fire extinguishing fluid.

A communication pipe 11 is connected to the end portions of the pair of injection pipes 7, 7 on the front side of the container 1, and both injection pipes 7,
7 is connected.

A pipe 12 located outside the container 1 is connected to a part of the communication pipe 11, and an on-off valve 13 is provided in the middle of the pipe 12, and a hose from a water supply or the like can be connected to the end.

14, 14 are protective covers provided along the injection pipes 7, 7, and the protective covers 14, 14 prevent deformation of the injection pipes 7, 7 due to the pushing force of dust and prevent clogging of the nozzles 10... It's getting old.

In addition, it is also possible to provide a nozzle in the communication pipe and use it as a pipe for cleaning or extinguishing fires.

The present invention has the above-described configuration, and after the garbage collection work is completed, the pushing device 4 is rotated upward to move the discharge plate 3 backward, thereby discharging the garbage. When performing cleaning work after that, connect a hose from the water supply to the pipe 12 and open the on-off valve 13, and water is sprayed onto the inner surface from the nozzles 10 of the injection pipes 7, 7.
Thereby, the inside of the container 1 can be cleaned.

Next, in the event of a fire, connect a hose from the water supply or a hose for sending fire extinguishing liquid to the pipe 12, open the on-off valve 13, and the water or fire extinguishing liquid will flow from the nozzles 10 of the injection pipes 7, 7. It can be sprayed on the inner surface and extinguish fires.

(g) Effects of the invention As described above, the present invention provides an injection pipe with a nozzle at the upper part of both side walls of the container, and makes it possible to supply water or fire extinguishing liquid to this injection pipe, so that when performing cleaning work, This eliminates the need for the operator to spray water from behind the container as in the past, allowing the operator to carry out cleaning work safely and hygienically.

In addition, when extinguishing a fire, it is no longer necessary to take the garbage out of the container and then extinguish it with a fire extinguisher, as was the case in the past, and there is no need to use a fire engine to spray water due to a delay in the initial extinguishment.

Furthermore, since the protective cover is provided along the injection pipe, deformation of the injection pipe and clogging of the nozzle due to the pushing force of the dust can be prevented.
