Specific embodiment
The utility model is described in more detail with reference to the accompanying drawings and examples.
The utility model discloses a kind of doctor blade devices for cleaning inner-walls of duct, with reference to shown in Fig. 1 to Fig. 4, bag
Scraper pedestal 1, telescoping mechanism 2 and rotary drive mechanism 3 are included, by stretching between the scraper pedestal 1 and rotary drive mechanism 3
Contracting mechanism 2 connects, and the outside of the scraper pedestal 1 is equipped with scraper 4, the rotary drive mechanism 3 for drive telescoping mechanism 2,
Scraper pedestal 1 and scraper 4 are rotated around the axle center of pipeline, the telescoping mechanism 2 for drive scraper pedestal 1 and scraper 4 it is close or
Away from inner-walls of duct.
In above-mentioned doctor blade device, telescoping mechanism 2, scraper pedestal 1 and scraper can be driven under the action of rotary drive mechanism 3
4 rotate in pipeline, and are cleared up using the dirt that scraper 4 adheres to inner-walls of duct, when tackling the pipeline of different size,
Under the action of telescoping mechanism 2, scraper pedestal 1 and scraper 4 can be driven closer or far from inner-walls of duct, to adjust the footpath of scraper 4
To collapsing length so that scraper 4 can contact dirt but also be fed towards inner-walls of duct, and then improve plot efficiency, meanwhile,
Under the driving effect of telescoping mechanism 2, without configuring the scraper 4 of multiple models, equipment cost is effectively saved, in addition, this practicality
It is new without chemical solvents such as cleaning solutions, secondary pollution can be avoided, and then meet environmental requirement.
In the present embodiment, further include for scraper 4 provide elastic buffer mechanism, in particular to, worn on the scraper pedestal 1
Equipped at least one connecting rod 5, the connecting rod 5 is slidably connected with scraper pedestal 1, and the scraper 4 is fixed on the end of connecting rod 5
Portion is folded with elastic component 6 between the scraper 4 and scraper pedestal 1, and scraper 4 is driven by the elastic force that the elastic component 6 applies
To the lateral expansion of scraper pedestal 1.Under the cushioning effect of said structure, not only it is avoided that scraper 4 bears rigid stress, also makes
The state that scraper 4 remains out stretching, extension is obtained, so as to reliably contact the dirt of inner-walls of duct, to improve clean-up performance.
In order to enable 4 stress equalization of scraper, wear that there are two connecting rod 5, the elastic components 6 on the scraper pedestal 1
Between two connecting rods 5.
On the concrete structure of connecting rod 5, the described one end of connecting rod 5 away from scraper 4 is equipped with to keep out scraper pedestal 1
Limited block 50.Further, the elastic component 6 is spring.Specially compression spring.
In the present embodiment, the scraper 4 is elongated, and the knife face of the scraper 4 is embedded with multiple positioning beads 7, and described
Positioning bead 7 is protruded to the outside of scraper 4.Further, the positioning bead 7 is ball.Also being abutted between ball and knife face has
Ball spring so that ball has the elastic stress flexed outward.The effect of above-mentioned positioning bead 7 is, when scraper 4 extends to pipe
When at road inner wall, the knife face and inner-walls of duct that can avoid scraper 4 contact directly, to prevent scraper 4 from damaging inner-walls of duct.
As a kind of preferred embodiment, the knife face width of the scraper 4 is gradually reduced along the length direction of the scraper 4, with order
The knife face both sides of the scraper 4 form intilted blade 40.The scraper 4 of this structure can be incited somebody to action using inclined blade 40
The dirt cleaned up is released outside pipeline, and in order to reach this effect, when installing scraper 4, one end that knife face can be made wider is goed deep into
In pipeline, the relatively narrow one end of knife face is close to pipeline exit.
Further, two sides of the scraper 4 are recessed and form intrados 42 respectively inwards, and the blade 40 is located at
The edge of intrados 42.The scraper 4 of this structure, the blade 40 and intrados 42 of both sides form the knot of approximate " plow-shape "
Structure so that scraper 4 can effectively be implemented to cut, and then improve dirt cleaning effect.
Enter pipeline for the ease of scraper or exited out of pipeline, the both ends of the scraper 4 and positioned at scraper 4 knife face on
It is respectively formed with fillet 41.
As a kind of preferred embodiment, the telescoping mechanism 2 is electric telescopic rod.The rotary drive mechanism 3 can be by subtracting
Speed motor and shaft composition.
The above is the utility model preferred embodiment, is not intended to limit the utility model, all in this practicality
Modification, equivalent substitution or improvement made in new technical scope etc., should be included in the model that the utility model is protected
In enclosing.
