Abstract
Description
Technical Field
[0001] This utility model relates to the field of floating debris cleaning technology, specifically to a floating debris cleaning and salvage device. Background Technology
[0002] To ensure the ship lift operates in good condition and prevent floating debris from damaging the lock sealing devices, navigation gates, and ship doors, it is necessary to clean up floating debris in the ship lift area. Currently, the main methods for cleaning floating debris are interception at the aqueduct and retrieval by debris-collecting vessels. The aqueduct interception method uses oil booms, but this is not very efficient. Debris-collecting vessels suffer from low speed, long round-trip distance, small cabin capacity, slow unloading, and low debris-collecting efficiency. Furthermore, prolonged operation during the flood season can lead to frequent equipment failures. The low efficiency of debris collection during the flood season has seriously affected the normal navigation of the ship lift. Therefore, there is an urgent need for a highly efficient floating debris cleaning and retrieval device to improve the navigation efficiency of the ship lift and protect the reservoir's aquatic environment. Utility Model Content
[0003] The purpose of this invention is to provide a device for cleaning and salvaging floating objects on water, addressing the aforementioned problems.
[0004] The technical solution of this utility model is as follows:
[0005] A floating debris removal and salvage device includes a float assembly and a nylon net. The nylon net is disposed below the float assembly. The float assembly includes at least two floats, at least one left-side brush float, and at least one right-side brush float. The floats have interlocking modular structures at both ends, with through holes and threaded holes on the modular structures. The left-side brush float is connected to the floats, two adjacent floats, and the floats to the right-side brush float via threaded pins to form a single unit. The float assembly and the nylon net are connected to an aqueduct, aqueduct, or ship compartment via cables.
[0006] With the above structure, the device is installed at the aqueduct opening, in the aqueduct, or inside the ship's compartment, and collects floating objects on the water by actively capturing or passively blocking them.
[0007] Furthermore, the building block structure at one end of the float is a four-corner protrusion structure, with a through hole on the upper protrusion structure and a threaded hole on the lower protrusion structure; the building block structure at the other end of the float lacks a four-corner structure and fits into the four-corner protrusion structure; and a through hole is provided on the four-corner structure; the threaded pin can be fixed in the threaded hole through the through hole of the adjacent float.
[0008] With the above structure, the pontoon assembly can be assembled according to the width of the aqueduct opening, aqueduct, or ship compartment, making it convenient to use the device in areas of different lengths; in addition, at least two connected pontoons provide buoyancy for the device.
[0009] Furthermore, the pontoon has mooring holes on both sides for connecting nylon nets.
[0010] The above structure includes mooring holes for connecting the nylon net, allowing the length of the nylon net to be adjusted according to the width of the aqueduct opening, aqueduct, or ship compartment. Each pontoon can be connected to the upper end of the nylon net, ensuring structural stability during use.
[0011] Furthermore, one end of the left-side brush float is provided with a modular structure that can fit into the float, and the other end is provided with a brush; and the modular structure lacks a four-corner structure, and can be connected to the float by a threaded pin.
[0012] Furthermore, one end of the right-side brush float is provided with a building block structure that can fit into the float, and the other end is provided with a brush; and the building block structure is a four-corner protruding structure that can be connected to the float through threaded pins.
[0013] With the above structure, brushes are installed at one end of the left and right brush floats for contact with and movement against the wall, while the brushes can also block floating objects.
[0014] Furthermore, at least two weights are provided below the nylon mesh.
[0015] The aforementioned structure, with its weighted counterweight, keeps the nylon netting of the device vertical, improving the efficiency of cleaning floating debris.
[0016] Furthermore, the upper sides of the nylon net are connected to the aqueduct opening, aqueduct, or ship compartment via cables on the nylon net.
[0017] Furthermore, the lower ends of the nylon net are connected to the aqueduct opening, aqueduct, or ship compartment via nylon net cables on both sides.
[0018] With the aforementioned structure, the device described herein can be towed away from the working area by a ship in one go, and then retrieved to the dock using a dock lifting device. This not only solves the problem of floating debris affecting navigation in the ship lift area, but also avoids the need for secondary retrieval.
[0019] Furthermore, the nylon net is connected to the mooring bollards of the aqueduct opening, aqueduct, or ship compartment via cables on the nylon net and cables below the nylon net.
[0020] Furthermore, both ends of the pontoon assembly are connected to the mooring bollards of the aqueduct opening, aqueduct, or ship compartment via cables.
[0021] Compared with existing technologies, the beneficial effects of this utility model are:
[0022] When the ship lift is not in operation, the device described in this application is deployed at the ship lift aqueduct opening, aqueduct, or inside the ship compartment to collect floating debris through active capture or passive interception. Using a ship towing device, the collected floating debris is towed away from the working area in one go, and then retrieved to the dock using a dock lifting device. This not only solves the problem of floating debris affecting navigation in the ship lift area but also avoids the need for secondary retrieval. Attached Figure Description

The pontoon assembly and the nylon net 5 are connected to the aqueduct opening, aqueduct 13, or ship compartment by cables 10.
[0041] like Figure 2 , Figure 3 and Figure 4 As shown, the modular structure at one end of the float 3 has four protruding corners, with a through hole 7 on the upper protruding part and a threaded hole 8 on the lower protruding part; the modular structure at the other end of the float 3 lacks the four-corner structure and fits into the four-corner protruding structure; the lack of the four-corner structure also has a through hole 7; the threaded pin 2 can be fixed in the threaded hole 8 through the through hole 7 of the adjacent float 3. Mooring holes 9 for connecting nylon nets 5 are provided on both sides of the float 3.
[0042] like Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the left brush float 1 and the right brush float 4 are floats equipped with long nylon brushes. One end of the left brush float 1 is provided with a modular structure that can fit into the float 3, and the other end is provided with a brush; the modular structure lacks four corners and can be connected to the float 3 via threaded pins 2.
