Specific embodiment
Following embodiment only exists in illustrative purpose, limits the scope of the invention without being intended to.
Embodiment 1
Referring to Fig.1-3, a kind of magnetic inductive depositing dust hard shoulder, including pier body 1, the bottom end of pier body 1 are fixedly connected with counterweight
Pedestal 2 successively offers movement chamber 3, loss of weight chamber 4 and storage chamber 5, loss of weight chamber 4 under upper in pier body 1 and on the one hand reduces pier body
1 making material saves cost, and whole decentralization is on the other hand made under the collective effect of counter weight base 2, improves pier body
1 stability avoids easily with regard to there is a phenomenon where toppling over, the inner wall of movement chamber 3 is sealedly and fixedly connected and has partition 6, pier body 1 about
Partition 6 is symmetrically arranged with two atomizing de-dusting apparatus, and each atomizing de-dusting apparatus includes being slidably connected with movement 3 inner wall of chamber sealing
Airtight piston 7, airtight piston 7 is fixedly connected with reset spring 9 with the side side wall close to each other of partition 6 jointly, and pier body 1 is right
Title is opened up there are two venthole 16, and two ventholes 16 are located between partition 6 and airtight piston 7, maintain partition 6 with it is airtight
The air pressure in movement chamber 3 between piston 7 is identical as ambient atmosphere pressure always, avoids the proper motion for influencing airtight piston 7.
Airtight piston 7 is fixedly connected with permanent magnet 8 far from the side side wall of partition 6, and pier body 1 and partition 6 are all made of magnetic cup
It covers material to be made, the permanent magnet 8 in two atomizing de-dusting apparatus is independent of each other, and pier body 1 is equipped with booster cavity in the lower section of movement chamber 3
11, the side side wall of movement chamber 3 offers the one-way air inlet channel 10 being in communication with the outside, and is equipped with gas in one-way air inlet channel 10
Body can only be from extraneous one-way flow to the check valve of movement chamber 3, and the inner bottom surface of movement chamber 3 offers the list being connected to booster cavity 11
To Pressure channel 12, gas is equipped in unidirectional Pressure channel 12 can only be unidirectional from movement 3 one-way flow of chamber to booster cavity 11
Valve, the side side wall of booster cavity 11 offer outlet passageway 13, and pressure valve, the side of storage chamber 5 are equipped in outlet passageway 13
Side wall offers the water injection hole being in communication with the outside, and the interior bottom of storage chamber 5 is equipped with the capillary 15 being vertically arranged, capillary 15
Internal diameter is sufficient to make water to rise to the lower section of trident spray channel 14 under capillary action, and storage chamber is run through in the upper end of capillary 15
5 inner top surface and the lower section for extending to outlet passageway 13, pier body 1 offer outlet passageway 13, capillary 15, extraneous three be connected to
Pitch spray channel 14.
In the present embodiment, since the shell of traffic virtually all has ferrimagnet production, whenever vehicle face
When pier body 1, permanent magnet 8 all can generate magnetic attraction to vehicle, and airtight piston 7 is driven to overcome the frictional force of itself and movement 3 inner wall of chamber
It is moved towards the direction in one-way air inlet channel 10, stretch reset spring 9 and increases the air between airtight piston 7 and movement chamber 3
It is depressed into booster cavity 11, when vehicle passes through pier body 1, airtight piston 7 will reply under the restorable elastic force of reset spring 9
To initial position, outside air enters in movement chamber 3 automatically by one-way air inlet channel 10 under the action of atmospheric pressure, and more
When vehicle passes through pier body 1, airtight piston 7 then will do it linear reciprocating motion, and in addition gas pressure increases to pressure in booster cavity 11
It is automatically opened after the preset pressure value of power valve, high pressure gas forms high-speed flow by trident spray channel 14 and flow to the external world, stores
Water in water cavity 5 overcomes gravity to improve by capillary 15 to the height for closing on trident spray channel 14 automatically under capillary action
Degree, according to bernoulli principle, flow velocity is fast, and pressure is small, and the water in capillary 15 is automatically by the outflow of trident spray channel 14 and quilt
High pressure draught tears to form misty ejection, carries out depositing dust operation to road.
It is worth noting that: the present apparatus can carry out prolonged depositing dust operation, only need to manually pass through water injection hole to storage chamber 5
The interior appropriate water liquid of injection；With the progress of science and technology, automatic water supplement pipeline can be built in urban road subterranean layer completely,
And closing is automatically opened by solenoid valve, depositing dust is on the one hand carried out, on the other hand road can be conserved.
