Abstract
The utility model discloses an electric pneumatic brass-wind instrument device, comprising an outer shell and an end cover. The utility model is characterized in that a motor is arranged between the outer shell and the end cover, and a rotor is arranged on a shaft of the motor. The outside of the rotor is sheathed with a vane pump, and vanes are arranged on the vane pump. A diaphragm for pronouncing is arranged on a sealing cover, and the outer end of the outer shell is also provided with a horn base and a horn which is also provided with an air filter net. The vanes generate compressed air under the centrifugal force and the eccentricity action, and the compressed air enters the horn base from an airflow channel in the pump to impulse the diaphragm for pronouncing to send out sound. The utility model has the advantages of compact structure, reasonable design and convenient installation and maintenance, and is suitable for various ships.
Description
The utility model relates to beeper, especially relates to a kind of electric pneumatic sound number device.
At present China inland river and coastal transport oceangoing ship, fishing boat use electric horn mostly, and the electric horn sound wave is short, only is applicable to short distance, do not meet a regulation of " People's Republic of China's Rules for Preventing Collisions on Inland Waters " chapter 4 the 40.Notification number is that the Chinese patent of GG87205741 " is equipped with the compressor-operated air horn of air cleaner " though can send automobile or the required aural signal of ship, but it adopts cylinder body pressurized air, complex structure, and fault is more, it is very inconvenient to keep in repair, and cylinder body is also shorter serviceable life.
The purpose of this utility model is to provide all electric pneumatic sound number devices very easily of a kind of compact conformation, reasonable in design, installation and maintenance.
The purpose of this utility model is achieved in that the utility model comprises shell and end cap, feature is between shell and end cap motor to be installed, on the axle of motor, rotor is installed, be with and the friction tight vane pump of rotor in the rotor outside, on vane pump, be processed with blade, rotor and vane pump are installed between end cap and the gland bonnet, in the middle of gland bonnet, be processed with gas channel in the pump, the gland bonnet outer end is equipped with the pronunciation diaphragm, the pronunciation diaphragm is equipped with sealing outward and regulates pad, in the middle of the shell outer end, the horn seat is installed, on the horn seat horn is installed.
Air intake place at the vane pump of shell is equipped with airstrainer; Blade has the 2-10 sheet.
The utility model is because design has vane pump, blade in the vane pump can be under the wobbler action of the centrifugal action of motor high speed rotating and rotor and vane pump, pressurized air when producing air inlet, compressed air enters the horn seat by gas channel in the pump, impulsion pronunciation diaphragm is sounded, therefore it has compact conformation, advantage is very easily maintained all in reasonable in design, installation and maintenance, the pump housing adopts high abrasion cast iron to make, blade adopts nonmetallic materials to make, resistance to wear, anticorrosive, the utility model is applicable to all kinds of ships.
Fig. 1 is a structural representation of the present utility model.
Below in conjunction with embodiment and contrast accompanying drawing the utility model is described in further detail.
Between shell 11 of the present utility model and the end cap 9 motor 10 is installed, the power-line terminal 14 of motor 10 is installed outside shell 11.On the axle of motor 10, rotor 8 is installed, be with and the friction tight vane pump 6 of rotor in rotor 8 outsides, on vane pump 6, be processed with eight blades 7, rotor 8 and vane pump 6 are installed between end cap 9 and the gland bonnet 5, air intake place at the vane pump 6 of shell 11 is equipped with airstrainer 12, in the middle of gland bonnet 5, be processed with gas channel 13 in the pump, pronunciation diaphragm 4 is installed in gland bonnet 5 outer ends, the pronunciation diaphragm 4 outer sealing adjusting pads 3 that are equipped with, in the middle of shell 11 outer ends, horn seat 2 is installed, horn 1 is installed on the horn seat 2.
When pressing push button, motor 10 energising rear axle high speed rotating, drive also high speed rotating of rotor 8, vane pump 6, blade 7 is under the wobbler action of the centrifugal action of high speed rotating and rotor 8 and vane pump 6, to compress from the air that airstrainer 12 enters, pressurized air enters horn seat 2 by gas channel in the pump 13, and impulsion pronunciation diaphragm 4 is sounded.Airstrainer 12 can filtered air, prevents that dust, sandstone from entering vane pump 6, damaged blade pump 6.
