Specific embodiment
The technical issues of in order to keep the utility model solved, technical solution and beneficial effect are more clearly understood, below
In conjunction with attached drawing and embodiment, the utility model is further elaborated.It should be appreciated that embodiment described herein is only used
In explaining the utility model, it is not used to limit the utility model.
As shown in figures 1 to 6, a kind of baffle type safeguard structure applied to river and lake water channel dredging cutter head, including fixing sleeve is clear
Barrier shield 1 on silt cutter head 4, the barrier shield 1 include keeping careless equal each other by least three spacing
Set up the strip metal set separately and twist the curved barrier protecting cover 3 for piecing together outer arch shape, one end of the barrier protecting cover 3 with
Dredging cutter head 4 is fixed to each other locking, and barrier protecting cover 3, which wraps dredging cutter head, contact it may in river with script
The facilities such as pipelines and river and lake bank slope slope foot such as water, electricity, coal gas, communication in river form firm transfer barrier, even if unexpected
Relevant pipeline, line and/or facility in water channel are touched, and is first touched by barrier protecting cover, then takes advantage of a situation and pushes open, due to
Every protecting cover as dredging cutter head 4 have very strong destructiveness, therefore can be effectively protected relevant pipeline in water channel,
Line and/or facility, when barrier protecting cover 1 touches pipeline and/or related facility, operator can also be readily recognized that, after
And take the measures such as timely and effective evacuation.
There are the differences of many essence for mentioned barrier shield 1 and existing common shield, existing anti-
Shield is provided to solve to prevent collision or filtration problem, therefore is all using relatively intensive mesh enclosure shape structure, which
Due to by mud completely or it is most of completely cut off, at all into not going or be difficult into the work conveyed to the mud of dredging cutter head
Portion leads to the work that cannot realize dredging well.
Barrier shield 1 in this programme must also be ensured that dredging cutter head 4 not only for solving the problems, such as barrier
It can work according to normal and efficient mode, in order to not influence the collection cleaning of mud while ensureing barrier action,
Careless spacing must be kept between more 2, shape metal, carries out pine so that mud uncrossed can enter dredging cutter head
It is dynamic, and smoothly taken away by dredger, because its main function is not only to obstruct, and do not interfere with normal loosening mud
Work.
As shown in Figure 1-3, the effect of the barrier shield 1 of this programme clearly is not only barrier dredging cutter head 4 and phase in water channel
The effect of the pipeline, line and/or facility of pass, while when also needing mobile with hull in view of dredging cutter head 4, water flow is to ship
The influence of body and dredging cutter head 4 itself, in order to make guiding stability of the dredging cutter head preferably in water flow, barrier is anti-
Shroud body 1 preferably twists the curved cover for piecing together bowed out curve shape using at least three strip metals 2, wherein two strip gold
Belong to 2 low spots for being located at relative level, another is located at the high point of relative level, constitutes stable triangular and is distributed supporting point, wherein position
It can be slided in the stable guiding of water channel in two strip metals 2 of low spot.
As Figure 4-Figure 6, as another embodiment, in the environment of for stronger working strength, barrier protecting cover 3 is also
It can be adopted as five strip metals 2 and twist the curved cover for piecing together bowed out curve shape, wherein two strip metals 2 are located at relatively
Horizontal low spot, another three are uniformly distributed, and constitute five jiaos of Stable distritation supporting points, wherein being located at two strip metals 2 of low spot
It can be slided in the stable guiding of water channel, above mentioned strip metal 2 generallys use the bar of steel.
Certainly the above is only the most preferred set-up mode of strip metal 2, utility model people sends out when actual experiment
Existing, usual 3-8 or so root can also be able to carry out relevant dredging work, but overstocked strip metal is arranged, and is certain to lead
It causes dredging effect not good enough or dredging work can not be carried out.
As the mounting structure of barrier protecting cover 1, one end of barrier protecting cover 1 is equipped with to be interlocked with 4 phase of dredging cutter head
The mounting part 6 of tight and fixed 2 one end face of strip metal, the other end are equipped with and are fixedly connected with 2 other end of strip metal
Water conservancy diversion fixed part 6, the mounting part 5 are cricoid retaining collar 8.
As another preferred embodiment of mounting part 5, mounting part 5 is consolidating for two split semicirculars
Determine lantern ring 8, the retaining collar of two semicirculars offers the fixed hole position 9 being correspondingly arranged.
Water conservancy diversion fixed part 6 is the metallic object of semi-spherical shape or truncated cone shape, and outer dimension is less than mounting part 5,
The resistance that water flow is effectively reduced when water flow variation and current deflecting, shipping agency and mobile dredging cutter head can preferably be adapted to
Power keeps dredging work more more smooth, improves efficiency.
As shown in figures 2 and 5, in order to further preventing the service life of strip metal, as far as possible buffering stress, metal
Outer layer can be coated with snubber elastomeric plastic cement protective coating 7, such as soft plastic etc..
As shown in figs. 3 and 6, as the embodiment of application range, dredging cutter head 4 is grab type dredging cutter head, common strand suction
Formula dredging cutter head or any other a type of dredging cutter head,.
A kind of baffle type safeguard structure structure applied to river and lake water channel dredging cutter head of the utility model is simple, processing cost
Low, cutter head, which is not easy to be wound by sundries, to be blocked, and be can effectively solve the problem that water channel becomes silted up to dredge in work by baffle type safeguard structure and is twisted
Knife blade physical damage caused by the facilities such as water, electricity, coal gas, communication pipe and river and lake bank slope slope foot in river, reduce by
Security risk caused by this
The above-mentioned preferred embodiment for being only used for illustrating, within the spirit and principle of the utility model institute
Any modifications, equivalent replacements and improvements of work, shall fall within the scope of the present invention.
