The content of the invention
In view of this, the present invention provides a kind of tubaeform compartment of garbage compression box for solving or partly solving the above problems.
To reach the effect of above-mentioned technical proposal, the technical scheme is that：A kind of tubaeform compartment of garbage compression box,
Garbage compression box is tubaeform, and compartment is concentric reducer compartment and shrinks shape compartment, it is characterized in that：Using compartment roof plate, side plate, ladder
Shape base plate is constituted, and is manufactured into horn-like, front end more than rear end, the steel construction compartment of contraction shape；Compartment roof plate, side plate, trapezoidal bottom
Plate is all that, using computer design, the steel plate that numerical control setting-out is critically cut, sheet metal process is shaped, compartment roof plate surface is oblique
Circular conical surface；
The horizontal direction of compartment roof plate is inclined, and the low rear end in front end is high, and nose width is less than rear end, is oblique cone
Face；Horizontal direction is straight line after trapezoidal base plate manufacture, but nose width is again smaller than rear end, is trapezoidal；Before the side plate on both sides
End is that, towards contract, rear end is more than front end, is oblique cone face；
Garbage compression box is tubaeform, and compartment front and rear profile size differs about 30~60 millimeters, and 1 ° of angle of inclination is presented loudspeaker
Shape, 6~42 cubic metres of volume；Compartment roof plate be by 4-5mm steel plates, blanking in echelon, the oblique cone face that sheet metal process is processed into；
Side plate is to use 4-5mm steel plates, and sheet metal process is processed into oblique cone face, and upper and lower flanging about 50mm takes with compartment roof plate, trapezoidal base plate
Connect and weld, in echelon, along middle flanging, both sides weld the steel plate cutting of platform floor with side plate overlap joint, postwelding garbage compression box
Tubaeform compartment presentation front end is small, the rear end horn-like casing of big oblique cone；
Closing valve is added in four corners of railway carriage top board, to ensure the sealing in compartment, closing valve is freely activity,
Enable is more easily operated to the rubbish in the tubaeform compartment of garbage compression box, and makes railway carriage top board and garbage-compressing
The other parts in case is tubaeform compartment are closely fitted；
Closing valve is opened comprising valve, spring, base, armature, permanent magnet, pressure device, special power supply, wire coil and door
Gateway controller；
One spring is housed in the side bottom of valve, spring is positioned on base, and base is connected with railway carriage top board, in valve
Door is lower to be equipped with armature, can under the influence of a magnetic field be locked at two positions up and down in valve, and permanent magnetism is housed around armature
Body, permanent magnet can radial polarised and ensure the closure of valve, and by the pressure device on valve, increased with valve
Pressure is stronger to ensure the closure of valve, and special power supply is housed in the top of valve, and power source special can provide 5V, 8V two kinds
Alternating current, around wire coil around armature, connects alternating current to wire coil, and control equipped with door switch controller
The closing of valve is connected with armature, is made up of Hall chip, the closing of valve and opening are divided into opening, door switch controller
Valve locking in the case of valve closing, no power in the case of energization, energization situation lower valve are opened, standing valve in the case of no power
Four kinds of the open position of door；
The process of valve closing is as follows in the case of energization：
Special power supply passes to the alternating current of 5V to wire coil, and the polarity of power supply is positive level, gold for the left end of wire coil
The right-hand member for belonging to coil is negative level, and door switch controller is divided into opening end and shutdown side, opens end in the N poles of permanent magnet, closes
S grades in permanent magnet is held, by determining the voltage that special power supply is powered, judgement is needed valve closing, electric current in wire coil
Rapid growth, thus a magnetic pole is produced, the magnetic pole is relatively weak compared with magnetic pole internal in armature, the inside in armature
Magnetic pole and its between generate that magnetic pole is poor, make the magnetic flux of permanent magnet, magnetic pole difference passes inwardly through armature and metal from the N poles of permanent magnet
Gap between coil, armature is entered by wire coil, is then as closed downwards through the N poles of permanent magnet inside armature
Closed end, then increased magnetic flux and suction in shutdown side, and make valve closing in the presence of the net equilibrant force of Hall chip,
And confirm the position of valve closing by detecting the flux change around permanent magnet, valve closing is illustrated when changing greatly
Sealing is not strong, and by the pressure device on valve, intensified pressure is stronger to ensure the closure of valve on valve, works as permanent magnet
Around flux change it is little when, stop giving wire coil indirect current, into no power in the case of valve locking process；
The process of valve locking is as follows in the case of no power：
When power source special is powered off to the alternating current that wire coil is provided, need to be locked on the closed position of valve, gold
Current spikes on category coil are disappeared, and generate a magnetic pole, and suitable suction is produced so at the shutdown side of armature, therefore
Armature is locked in closed position, the magnetic flux of permanent magnet causes armature chatter, and produce magnetic padlock power to enter through the radial clearance of armature
Small gap is left and passing through armature makes valve be locked in closed position, between valve and spring, the precompressed amount of spring is given
Valve provides pressure in advance, and gap can reduce certain pressure loading；
The process that energization situation lower valve is opened is as follows：
Special power supply passes to the alternating current of 8V to wire coil, and the polarity that it is powered is positive level for the right-hand member of wire coil,
The left end of wire coil is negative level, and by determining the voltage that special power supply is powered, judgement needs to open on valve, reduces on valve
The pressure that produces of pressure device, reduce its pressure on valve, electric current rapid growth in wire coil, thus produce a magnetic
Pole, the magnetic pole is superimposed upon in the polarity of permanent magnet, electric current rapid growth in wire coil, also produces a magnetic pole, the magnetic pole
Relatively strong compared with magnetic pole internal in armature, it is poor to generate magnetic pole between the magnetic pole of permanent magnet and its, magnetic pole difference and
The magnetic pole that the process of valve closing is produced in the case of energization is conversely, make the magnetic flux of permanent magnet, magnetic pole difference is extremely inside from the S of permanent magnet
Through radial clearance, by between permanent magnet and wire coil, armature being entered by wire coil, then in armature downwards through
The S poles of permanent magnet, as open end, then increased magnetic flux and gravitation at opening end, when the gravitation for opening end exceedes shutdown side
Stress summation, stress summation includes spring force suffered by valve and the pressure loading received in shutdown side, so as to draw armature and push away
Movable valve to upward position, valve is thus opened, and subsequently enters the process of fixed valve open position in the case of being powered；
The process of fixed valve open position is as follows in the case of energization：
When current vanishes of the special power supply to power supply, the current attenuation in wire coil produces magnetic pole, the magnetic pole to zero
Polarity and no power in the case of valve locking the magnetic pole that produces of process conversely, the magnetic flux of permanent magnet is through wire coil week
Enclose, a sizable suction is kept end is opened, valve is maintained the state opened.
Useful achievement of the invention is：The tubaeform compartment of garbage compression box of the invention compared with straight-through shape compartment, not only
Without extra material, and no increase supernumerary structure and manufacturing equipment is increased, the several of compartment are only cleverly devised
What shape, rubbish is loaded and unloaded using such compartment, when running into icing temperature, and in the case where rubbish forms ice cube, in rubbish
