Problems solved by technology
In the event of strong winds, changes in storage yards and other factors, the angle of the spraying range will not be fixed, and the range of spraying angles will need to be adjusted manually. large, the spontaneous combustion environment is harsh, and the accuracy is not suitable for precision. The resulting spraying range is not in place, water is wasted, and the dust removal effect is not good.

Embodiment Construction
[0019] The structure of an electric spray gun for precisely controlling the spraying range of the present invention will be described in detail in conjunction with the drawings and embodiments.
[0020] The electric spray gun with precise control of the spraying range of the present invention includes a sealed shell shell, and the rotary table 8 and fixed gear 17 required for the rotation of the fixed spray gun are arranged inside the shell shell, as well as the transmission that provides the rotational power of the spray gun. DC motor 5, motor transmission gear 13, angle sensor 6 and feedback gear set 14 that provide feedback signal;
[0021] The rotary table 8 is connected with the internal pipeline 12 of the spray gun through the inline bearing on the top of the rotary table 8, the fixed gear 17 is coaxially fixed with the internal pipeline 12 of the spray gun passing through the bottom of the rotary table 8, and the transmission DC motor 5 and The angle sensor 6 is fixed o...

The invention provides an intelligent spray gun for accurately controlling a spraying range, which is connected with a pipeline inside the spray gun through an embedded bearing at the upper part of a rotary platform, a fixed gear and the pipeline inside the spray gun are coaxially fixed, a transmission direct-current motor and an angle sensor are fixed on the rotary platform through a fixed bracket, a motor transmission gear is connected to a transmission shaft of the transmission direct-current motor and meshed with the fixed gear, the rotary platform can rotate with the pipeline inside the spray gun as a shaft; a fixed flange and a water outlet pipeline are coaxially sequentially connected to the lower part of the fixed gear and the pipeline inside the spray gun; and a rotating shaft ofthe angle sensor is connected with a feedback gear set after passing through the lower part of the rotary platform, and a rotation quantity signal of the rotation of the spray gun is transmitted to the angle sensor. The invention has the advantages that a spraying angle signal is fed back through the angle sensor of the spray gun, and the motor rotation direction of the spray gun is changed through controlling an electric signal of the motor in real time so that the effect of accurately, rapidly and immediately changing the spraying range and the spraying angle is achieved. The invention provides the premise for the implementation of the remote concentrated spray control.
Description
technical field [0001] The invention relates to an electric intelligent spray gun with precise control of the spraying range, which is especially suitable for centralized control of sand and dust prevention, garden irrigation and the like in wharf yards and the like. Background technique [0002] Preventing dust, coal dust, dry coal spontaneous combustion and other phenomena is a necessary measure to be taken in dock yards and other places. For this reason, almost all docks are equipped with different types of sprinkler systems. [0003] Nowadays, spray guns on the market are generally divided into water-powered spray guns and electric-powered spray guns in terms of power types. No matter what kind of spray gun, the spray gun angle control generally uses two coaxial limit snap rings on the spray gun water pipeline to limit the spray gun angle. , It is necessary to manually visually inspect the spray angle range to fix the snap ring, so that the spray angle can be fixed. In ...
