Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy projects, and more specifically, to an underwater silt clearing and obstacle removal device. Background Art

[0002] In the control of marine pollution, the control of floating objects on the water surface is particularly important. Floating objects on the water surface are mostly produced near the coast and tend to accumulate in shallows. Shallows are difficult for ordinary ships to reach due to insufficient water depth, and manual cleaning on the shore is labor-intensive and inefficient, making it difficult to achieve ideal results.

[0003] During underwater dredging, there will be old fishing nets, cables, etc. left in the shallows of the sea. Some of these garbage will float on the surface of the shallows of the sea, and some will be deposited and pressed into the mud of the shallows of the sea. When traditional clear water dredging machinery is dredging, these garbage (such as fishing nets, ropes, etc.) will affect the operation of the dredging mechanism and the effect of dredging the shallows of the sea.

[0004] Therefore, it is necessary to propose an underwater silt clearing and obstacle removal device to solve the above problems. Utility Model Content

[0005] The utility model provides an underwater silt clearing and obstacle removal device to solve the problem that in the existing offshore shoal clearing process, the remaining waste fishing nets and cables in the offshore shoal easily affect the operation of the silt clearing mechanism and the silt clearing effect.

[0006] According to one aspect of the utility model, an underwater dredging and obstacle removal device is provided for assisting dredging on a salvage ship. The underwater dredging and obstacle removal device includes a mounting beam, a mounting plate and a salvage rake. The mounting plate is mounted on the mounting beam. The salvage rakes are multiple and are installed on the mounting plate at intervals. The salvage rakes are J-shaped and have V-shaped rake spikes in the middle.

[0007] Preferably, based on the above solution, both ends of the mounting plate are provided with lifting holes, steel wire ropes are installed in the lifting holes, and the steel wire ropes are controlled by a winch installed on the salvage vessel.

[0008] Preferably, based on the above solution, the rake spikes are welded to the middle of the salvage rake.

[0009] Preferably, based on the above solution, the rake comprises a base and spines, and the spines are symmetrically mounted on the base to form a V-shaped structure.

[0010] The utility model relates to an underwater dredging and obstacle clearing device. A mounting plate and a mounting beam are combined to form a mounting base. A salvage rake and rake spikes are installed on the mounting plate. The salvage rake and rake spikes can be used to quickly salvage underwater waste fishing nets and cables before underwater dredging, thereby clearing obstacles for subsequent underwater dredging and improving the dredging effect.

[0016] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0017] It will be understood that when used in this specification and the appended claims, the term "comprising" indicates the presence of described features, integers, steps, operations, elements and / or components, but does not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components and / or collections.

[0018] To simplify the drawings, only the parts relevant to the present invention are schematically shown in each figure. They do not represent the actual structure of the product. In addition, to simplify the drawings and facilitate understanding, in some figures, only one of the components with the same structure or function is schematically depicted or labeled. In this document, "one" not only means "only one" but also "more than one."

[0019] It should be further understood that the term "and / or" used in this specification and the appended claims refers to and includes any and all possible combinations of one or more of the associated listed items.

[0020] In the embodiments shown in the accompanying drawings, directional indications (such as up, down, left, right, front, and back) used to explain the structure and movement of various components of the present invention are not absolute but relative. These descriptions are applicable when these components are in the positions shown in the accompanying drawings. If the descriptions of the positions of these components are changed, these directional indications will also change accordingly.

[0021] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without inventive work.

[0023] See also Figure 1 , and combined with Figure 2 As shown, the utility model is an underwater dredging and obstacle clearing device, which is used for auxiliary dredging on a salvage ship to assist the underwater dredging mechanism and reduce the failure rate of the underwater dredging mechanism.

[0024] Specifically, the underwater dredging and obstacle removal device of the present invention includes a mounting beam 1, a mounting plate 2 and a salvage rake 3. The mounting plate 2 is mounted on the mounting beam 1 to form a mounting base, and the salvage rake 3 is multiple and installed at intervals on the mounting plate 2. The number of salvage rakes 3 can be set according to actual needs and the length of the mounting plate 2. It should be noted that the salvage rake 3 of the present invention is J-shaped, and a V-shaped rake spike 4 is provided in the middle of the salvage rake 3.

[0026] During use, the installation plate 2 is driven to move by the winch to adjust the movement trajectory of the installation plate 2 in the water, and garbage in different underwater positions is cleaned. During the cleaning process, the rake 4 and the salvage rake 3 can quickly salvage garbage in the water (such as fishing nets, ropes, etc.), so as to avoid it from being entangled in the dredging machinery during the subsequent underwater dredging process, thereby affecting its dredging effect.

[0027] Preferably, the harrow 4 of the present invention is welded to the middle of the salvage harrow 3 , and the harrow 4 includes a base 41 and spines 42 , and the spines 42 are symmetrically mounted on the base 41 to form a V-shaped structure.
