Description

Variable watering nozzle and eco-friendly water cleaning vehicle including the same{Variable flush nozzle and road sprinkler including the same}

The present invention relates to a variable water sprinkling nozzle and an eco-friendly water cleaning vehicle including the same, and more specifically, it is installed at the front lower end of the water cleaning vehicle and is made to perform cleaning while spraying water onto the road surface. It relates to a variable water sprinkling nozzle made to be adjustable according to the situation and an environmentally friendly water cleaning vehicle including the same.

Local governments or organizations that manage roads regularly perform cleaning work to collect dirt and garbage accumulated on roads that have already been constructed and used to keep the road surface clean.

Road cleaning work requires a lot of manpower and time due to the large area of cleaning, and the vehicle is designed to have a structure suitable for road cleaning because the risk of an accident is high due to the work being done in a situation in which the vehicle is driving around. 'Referred to as').

On the other hand, conventionally, a vacuum suction type cleaning car and a water spray type water cleaning car have been used.

The vacuum suction type cleaning car is configured to perform cleaning work on the road surface by collecting dust on the road surface through vacuum suction, and the vacuum suction type cleaning car has an advantage of effectively operating the cleaning car regardless of the season. have.

The water cleaning car is configured to perform cleaning work on the road surface by spraying water onto the road surface to wash off the dust on the road surface, and this sprinkling type cleaning car is used in winter because the water sprayed on the road surface freezes to form an ice section. This is impossible, and it has the disadvantage of not only using a large amount of water but also having to replenish it frequently.

However, the water cleaning car has a significantly less amount of dust scattered into the air during the cleaning process than the vacuum suction type cleaning car, and has the advantage of being able to cleanly remove dust on the road surface in one cleaning operation, so it is more effective for fine dust. There is an advantage that can be countered.

In order to efficiently operate the water cleaning vehicle, it is necessary to adjust the amount of water used for the cleaning operation according to the road surface condition or structure.

However, in the case of a water spray nozzle installed in a conventional water cleaning vehicle, it is configured to rotate up and down and left and right so as to change the spray angle or direction of water according to the state or structure of the road surface, or to adjust the injection pressure using a pump. It is constructed, but does not have a structure that directly controls the amount of water sprayed.

As described above, the conventional water cleaning vehicle is always configured to spray a certain amount of water to the road surface regardless of the structure or condition of the road surface, and unnecessary waste of water is generated, and frequent replenishment of water is required in the cleaning process, resulting in poor operation efficiency. There is this.
