Description
TECHNICAL FIELD
[0001] The utility model relates to underwater cleaning equipment technical field, concretely relate to a lake area underwater obstacle clearing device. BACKGROUND
[0002] The dredging engineering has a long history of development, and the technology is also relatively mature. At present, the dredging engineering has developed from the initial manual dredging to the mechanized and automated stage. At the same time, the scope of the dredging engineering is becoming more and more extensive, not only including the water areas such as river channels and ports, but also including the inland water areas such as lakes and reservoirs.
[0003] At present, the dredging of water areas such as lakes, reservoirs and estuaries often uses the environmental protection type cutter suction dredger. During the dredging construction process, some areas do not have perfect garbage collection facilities, so various garbage is discharged into the river channel along the ditch pipeline and enters larger water areas. Meanwhile, there are garbage such as abandoned fishing nets and crab pots in some larger water areas. If the environmental protection type cutter suction dredger is used for dredging in these water areas with garbage such as abandoned fishing nets and crab pots, the garbage such as abandoned fishing nets and crab pots will inevitably be wound around the reamer during the cutting process, and the reamer will be locked and unable to continuously work. CONTENT OF THE UTILITY MODEL
[0004] The utility model aims at providing a lake area underwater obstacle clearing device, which can salvage garbage such as abandoned fishing nets and crab pots, and facilitate the dredging construction of the environmental protection type cutter suction dredger.
[0005] To solve the above technical problems, the utility model adopts the following technical scheme:
[0006] A lake area underwater obstacle clearing device, comprising a plurality of curved supports arranged in order, wherein each curved support comprises a connecting portion, a curved portion and a flat portion; the connecting portions of adjacent curved supports are connected by a connecting frame, and the curved portions and the flat portions of adjacent curved supports are connected by a frame column; the curved portions and the flat portions of the curved supports are connected to the frame column in a staggered manner to form a plurality of leakage openings; a plurality of cleaning hooks are arranged on the flat portions of the curved supports, and the upper ends of the cleaning hooks are provided with barbs; the device further comprises a hanging ear mounted on the connecting frame.
[0007] The flat portion of the curved support extends a blade, and the blade has a pointed end.
[0008] The cleaning hooks are arranged in an inclined manner towards the curved portion.
[0009] The frame column of the curved portion is three, and the frame column of the flat portion is three.
[0010] The hanging ear is two, and two perforations are arranged on each hanging ear.
[0011] Compared with the prior art, the utility model has the following advantages and beneficial effects:
[0012] The utility model discloses a replace the original shovel of long arm underwater excavator bucket, through the ear hook installation on long arm underwater excavator. During the salvage process, the mixed silt sand and the like are left in the lake bottom through the leakage formed between the curved support and the frame column, and other garbage such as fishing net cages, woven bags and small stone blocks that need to be cleaned will not be screened out by the leakage, and the cleaning hook and the barbs on the cleaning hook can fix the fishing net cages and the woven bags. BRIEF DESCRIPTION OF DRAWINGS
[0013] Figure 1 It is the utility model three-dimensional structure diagram.
[0014] Figure 2 It is the utility model side view.
[0015] The interpretation of each reference numeral in the drawing is as follows:
[0016] 1-bent support, 11-connection part, 12-bent part, 13-flat part;
[0017] 2-blade; 3-frame column; 4-cleaning hook; 5-barb; 6-ear hook. DETAILED DESCRIPTION
[0018] The technical scheme in the utility model embodiment will be described clearly and completely in combination with the drawings in the utility model embodiment, so that the conception of the utility model, the solved technical problem, the technical features of the technical scheme and the brought technical effect have further understanding.
[0019] As shown in the drawing, Figure 1 A lake area underwater obstacle clearing device, comprising a plurality of curved supports 1 arranged in order, the curved support 1 comprising a connection part 11, a bent part 12 and a flat part 13;The connection part 11 of adjacent curved supports 1 is connected through a connecting frame, and the bent part 12 and the flat part 13 of adjacent curved supports 1 are connected through a frame column 3;The bent part 12 and the flat part 13 of the curved support 1 are connected with the frame column 3 in a staggered manner to form a plurality of leakages;A plurality of cleaning hooks 4 are arranged on the flat part 13 of the curved support 1, and the upper end of the cleaning hook 4 is provided with a barb 5;Further comprising an ear hook 6, which is installed on the connecting frame.
[0020] The original bucket of the long-arm underwater excavator bucket is replaced by the bucket, which is installed on the long-arm underwater excavator through the ear 6. In the salvage process, the mixed silt sand and the like are left in the lake bottom through the gap formed between the curved support 1 and the frame column 3, and other garbage such as fishing net cages, woven bags and small stones that need to be cleaned will not be screened out by the gap, and the cleaning hook 4 and the barb 5 on the cleaning hook 4 can fix the fishing net cage and the woven bag and other garbage. In the salvage process, the long-arm underwater excavator shakes up and down and left and right, and after the fixed garbage on the cleaning hook 4 is collected to a certain amount, the garbage is handled on shore; thereby reducing the problem that the garbage in the underwater silt which is not easy to break causes the cutter head of the cutter suction dredger to be wound and stuck, and continuous construction cannot be carried out.
[0021] Further, the flat part 13 of the curved support 1 extends the blade 2, and the blade 2 has a sharp end. The blade 2 facilitates the utility model to cut open the garbage on the lake bottom, and then salvage the garbage.
[0022] Further, the cleaning hook 4 is inclined to the direction of the curved part 12. The cleaning hook is inwardly inclined, which is convenient for fixing the garbage such as fishing net cages and woven bags more stably during the lifting process of the utility model after the garbage is salvaged.
[0023] The frame column 3 of the curved part 12 is three, and the frame column 3 of the flat part 13 is three.
[0024] The ear 6 is two, and two perforations are respectively arranged on the ear 6. The double ears 6 are convenient for the stability of the utility model after installation.
[0025] In the description of the utility model, "connection", "fixing" can be fixed connection, processing, welding, or mechanical connection. The specific meaning of the above terms in the utility model is understood.
[0026] In the description of the utility model, the terms "center", "up", "down", "horizontal", "inner", "outer" and the like only indicate the position relationship for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the device or element must have a specific orientation, so it cannot be understood as a limitation on the utility model.
[0027] Finally, it should be pointed out that: the above embodiments are only used to illustrate the technical scheme of the utility model, but not to limit it; although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that; it can still modify the technical scheme described in the foregoing embodiments, or make equivalent replacement for part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical scheme deviate from the scope of the technical scheme of the embodiments of the utility model.
