Detailed description of the invention
For summary of the invention of the present utility model, Characteristic can be understood further, hereby exemplify following examples and be described in detail as follows:
Refer to Fig. 1, the utility model comprises framework 2, being provided with the upper connection otic placode 1 for connecting lifting rope, being provided with connecting otic placode 3 in its front portion before connecting drag rope at the two ends at its top.Be connected with side by side in framework 2 multiple cross bar 5 make overall become cell structure, the top of cell structure be provided with multiple on rake teeth 6, be provided with multiple lower rake teeth 4 in the bottom of cell structure.
This scraper apparatus in use, carry out dragging by the towboat with hanging device to construct, particularly: the lifting rope of hanging device with on be connected otic placode 1 and connect, for carrying out the lifting of vertical direction to scraper device, comprising carries out vertically declining to scraper device makes it in place at the bottom and vertically lifts by crane together with net class foreign material whole scraper device after scraper construction terminates.Connect before drag rope is connected on otic placode 3, mobile for carrying out dragging when towboat moves to scraper device, make it along water-bed transverse shifting, upper rake teeth 6 and lower rake teeth 4 carry out hook joint removing to net class foreign material.
Upper connection otic placode 1 and front connection otic placode 3 can have various ways, as offered connecting hole on otic placode plate body, rope is fastened be connected on connecting hole and be fixed, or on otic placode, projection is set, rope is fastened be connected in projection and be fixed, or on otic placode, offer screwed hole, rope is adopted and is bolted in screwed hole, etc.It is envisioned that alternate manner can also be adopted to carry out rope and be connected the affixed of otic placode.
As shown in FIG., in the present embodiment, become to be designed to rectangle by framework 2 entirety, upper connection otic placode 1 point is positioned on the frame of framework 2 two broadsides, and front connection otic placode 3 is positioned on the frame on long limit on front side of framework 2.Particularly, the quantity of upper connection otic placode 1 is two, and divide the middle part being positioned at framework about 2 two broadside frames, the quantity of front connection otic placode 3 is two, is symmetrically distributed on long limit, the front side frame of framework 2.
Above-mentioned each connection otic placode constitutes the four point positioning structure of scraper device, need in actual construction to ensure that scraper device entirety has enough quality, as adopted metal pipe material or solid metal to make, such four point positioning can solve a stationarity difficult problem for scraper device underwater operation with the double action in deadweight.
Size aspect, the size of whole scraper device can set according to actual needs, and the width of ordinary circumstance underframe 2 is 2.0 meters, width is 0.5 meter; Each cross bar 5 be arranged in parallel on the frame 2 and is namely parallel to broadside frame as illustrated in the drawing, adjacent two cross bars 5 be set to 0.2 meter to 0.5 meter.
Harrow tooth structure aspect, in the present embodiment, situation as illustrated in the drawing: upper rake teeth 6 and lower rake teeth 4 include three rows from front to back, when scraper device transverse shifting, the rake teeth of each row carries out hook joint removing from upper and lower, from front to back to net class foreign material respectively.Particularly, be positioned at front-seat upper rake teeth 6 and be fixed on the frame on long limit on front side of framework 2, the upper rake teeth being arranged in row is fixed in the middle part of cross bar 5, and the upper rake teeth 6 being positioned at rear row is fixed on the frame on long limit on rear side of framework 2; Lower rake teeth 4 is symmetrical arranged with upper rake teeth about 6.
In order to promote the effect of scraper further, in the present embodiment, be positioned at front-seat upper rake teeth 6 and be disposed on bezel locations place, framework 2 long limit corresponding to each cross bar 5 front end, the upper rake teeth 6 being arranged in row is disposed on the middle part of each cross bar 5, front-seat upper rake teeth 6 is crisscross arranged in the horizontal direction with the upper rake teeth 6 of middle row, and the upper rake teeth 6 being positioned at rear row is arranged on bezel locations place, framework 2 long limit corresponding to each cross bar 5 rear end.Lower rake teeth 4 is arranged equally.Above-mentioned tooth-shape structure can promote the hook joint elimination effect to net class foreign material, and the rake teeth of front-seat and middle row is comparatively sparse and be staggered front to back setting, and the rake teeth of rear row is comparatively intensive, avoids the omission to net class foreign material.
The semicircle that upper rake teeth 6 and lower rake teeth 4 are all designed to bend towards front is hook-shaped, and the hook-shaped advantage of semicircle can ensure to remove the hook joint of water-bed net class foreign material, can ensure that net class foreign material can be removed by operating personnel comparatively effortlessly again in lifting to the water surface.It is envisioned that the upper rake teeth 6 of other structure and lower rake teeth 4 also can reach above-mentioned effect, as smooth bent rod structure etc., above-mentioned equivalent distortion is all included within protection domain of the present utility model.
Operating process: in enforcement uses, a towboat with loop wheel machine need be equipped with, utilize wire rope to be connected with the loop wheel machine of towboat by upper connection otic placode 1, and seabed is put in the lifting of this scraper device.By towboat traction, net class foreign material are cleared up in seabed by this scraper device.Time outside towboat traction to works area, the water surface of being sling out by this scraper device, to clear up the foreign material that scraper device adheres to.So repeatedly, to reach the object removing dredge boat construction area net class foreign material, reduce dredge boat construction by its influence degree, ensure the production efficiency of boats and ships.
This scraper device is equally applicable to the scraper construction in the waters such as river bed, lakebed.
