This patent application claims the benefit and priority of Chinese Patent Application No. 202311662953.X filed with the China National Intellectual Property Administration on Dec. 6, 2023, the disclosure of which is incorporated by reference herein in its entirety.
The present disclosure relates to the technical field of environment-friendly devices, and in particular to a floating object cleanup device.
As society develops, an increasing number of floating objects are found on the water surfaces of scenic areas and on urban and rural rivers, which significantly affects the daily life of people. Currently, most floating objects in these smaller bodies of water are removed manually, a method that is both inefficient and labor-intensive. To address this problem, a floating object cleanup vessel was developed under Chinese Patent No. ZL201410606202.0, which greatly improves the salvage efficiency of floating objects. During actual application, however, the inventor found that although the collection efficiency of floating objects on the water surface is greatly improved due to a large water surface collection port formed by a towing vessel and an intercepting arm during use, the storage problem of the towing vessel and the intercepting arm is troublesome when there is no need to use the towing vessel and the intercepting arm.
In order to solve the technical problem discussed above, in the Chinese invention patent No. ZL202211146804.3, the floating object cleanup vessel was upgraded, and a towing vessel storage device was arranged at a position, adjacent to the stern, of the collection vessel, such that the towing vessel can be placed in the towing vessel storage device in the non-working state, and the intercepting arm is arranged adjacent to the side wall of the collection vessel.
However, during actual application of the upgraded floating object cleanup vessel, it has been found that the measure of making the intercepting arm adjacent to the side wall of the collection vessel by fixing the towing vessel has some shortcomings in the positioning of the intercepting arm as follows. Since the intercepting arm is long and has a certain flexibility, the fixation of only one end adjacent to the towing vessel cannot ensure that the intercepting arm is adjacent to the side wall of the collection vessel (there will be the phenomenon that the intercepting arm hangs down and the non-fixed end moves far away from the side wall of the collection vessel under the action of water flow), which causes great interference (affecting the speed and endurance of the cleanup vessel) when the cleanup vessel is not in a cleanup state (the cleanup vessel is adjusted from a semi-submersible mode to a normal mode).
The following summary is provided to facilitate an understanding of some of the innovative features unique to the disclosed embodiments and is not intended to be a full description. A full appreciation of the various aspects of the embodiments disclosed herein can be gained by taking the entire specification, claims, drawings, and abstract as a whole.

Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art. The terminology used in the description of the present disclosure herein is only for the purpose of describing specific embodiments, and is not intended to limit the present disclosure. The term “and/or” used herein includes any and all of combinations of one or more related listed items.
As shown in
Each of both sides of the collection vessel 100 is provided with an intercepting arm tightening arm 110, and an arm supporting member 120. The intercepting arm tightening assembly 110 is configured to clamp and fix the intercepting arm 300 to a side surface of the collection vessel 110 by applying pressure to the intercepting arm 300. A main body of the arm supporting member 120 is plate-shaped and configured to bear the intercepting arm 300.
The intercepting arm tightening assembly 110 includes rotating shaft sleeves 111, positioning blocks 112, a rotating shaft 113, and tightening arms 114.
Multiple rotating shaft sleeves 111 are fixed to positions on a side surface of the collection vessel 100 adjacent to the top of the side surface of the collection vessel 100 through the positioning blocks 112. A spacing between each rotating shaft sleeve 111 and the side surface of the collection vessel 100 is 1-1.3 times width of the intercepting arm 300. An axial direction of the rotating shaft sleeve 111 is the same as, or similar to, a length direction of the collection vessel 100.
The rotating shaft 113 is a straight hard rod and penetrates through all rotating shaft sleeves 111 on one side of the collection vessel 100. An elastic member is positioned on a position where the rotating shaft 113 contacts with the rotating shaft sleeve 111, and the elastic member is preferably a leaf spring or a torsional spring. The elastic member is configured to accumulate and release elastic potential energy to further assist the tightening arm 114 to clamp and fix the intercepting arm 300.
The tightening arm 114 is rod-shaped, or plate-shaped, has a top end fixed to the bottom of the rotating shaft 113, and is configured to clamp the intercepting arm 300. In a normal state, the tightening arm 114 is in an inclined state due to the existence of the elastic member. A bottom end of the tightening arm 114 is closer to the side surface of the collection vessel 100 than the top end. When the intercepting arm 300 is clamped, the tightening arm 114 is abutted against the intercepting arm 300.
When the intercepting arm 300 needs to be tightly clamped, the tightening arm 114 is rotated first to make the elastic member accumulate potential energy, and when the intercepting arm 300 is placed between the tightening arm 114 and the collection vessel 100, the tightening arm 114 is put down.
The arm supporting member 120 is an L-shaped plate fixed to a side wall of the collection vessel 100. There is one or more arm supporting members 120 on one side of the collection vessel 100. An opening of the arm supporting member 120 is towards the collection vessel 100. Further, the arm supporting member 120 includes a bearing plate and a stop plate. The bearing plate is horizontally arranged and has a flat top surface. A width of the bearing plate is 1.1-1.5 times that of the intercepting arm 300, and the bearing plate is fixed to the side wall of the collection vessel 100. The stop plate is vertically arranged, fixed on the bearing plate, arranged away from an edge of the collection vessel 100, and configured to prevent the intercepting arm 300 from sliding down the bearing plate.
During actual use, after the crew detaches the intercepting arm 300 from the collection vessel 100 when a hull is in semi-submersible mode, the tightening arm 114 is lifted up, and then the floating intercepting arm 300 is positioned between the tightening arm 114 and the collecting vessel 100 in a pull-push manner. Afterwards, the tightening arm 114 is put down. The pressure applied to the intercepting arm 300 by the intercepting arm tightening assembly 110 forces the intercepting arm 300 to move to the side surface of the collection vessel. After the cleanup vessel is adjusted from the semi-submersible mode to a normal mode, the intercepting arm 300 is naturally placed on the arm supporting member 120 due to the loss of buoyancy (affected by its own weight).
Further, the intercepting arm tightening assembly 110 is also provided with an auxiliary rod 115. The auxiliary rod 115 is a hard rod body. The rotating shaft 113 is provided with one or more holes for the auxiliary rod 115 to insert. During use, the auxiliary rod 115 can be inserted into the hole on the rotating shaft 113 to rotate the rotating shaft 113.
Preferably, in order to save labor, the hole into which the auxiliary rod 115 can be inserted extends into the tightening arm 114.
Further, the tails of the two towing vessel storage devices 140 on the collection vessel 100 are fixedly connected by a protecting rod 130 to form a propeller protection area, thus preventing propellers of the collection vessel from being damaged by foreign objects. The protecting rod 130 is a hard rod body, or a rubber rod body.
The technical solution provided by the embodiments of the present disclosure has the following technical effects or advantages.
The technical problem that the existence of the intercepting arm is easy to seriously affect the speed and endurance of a cleanup vessel as the floating object cleanup device in the prior art has relatively poor positioning effect on the intercepting arm in a non-cleaning state is effectively solved. Moreover, as the intercepting arm can be conveniently stored and positioned by the floating object cleanup device when not in use, the technical effect that the existence of the intercepting arm has less interference on driving can be achieved.
Considering that the floating object cleanup device in the above embodiment has certain limitations in cleanup, due to the limitation of the own structure of the cleanup device, the minimum sailing depth of the towing vessel 200 needs to be satisfied during refuse cleanup, so the cleanup effect of floating objects in shoals near the shore is poor. In order to further improve the practicability, passability and applicability of the present disclosure, overcome the above limitations, make the floating object cleanup device efficiently clean up the floating objects in a shallow water area on the shore, improve the cleanup effect and avoid the damage to a hull of the towing vessel 200, the structure of the intercepting arm 300 is optimized and improved on the basis of the above embodiment, which is specifically as follows.
As shown in

The force guide rod 323 is a straight hard rod, with a length 0.5-0.7 times that of the base arm 310. One end of the force guide rod 323 is rotatably connected to an end, away from the storage cavity 311, of the positioning tail rod 321 through the rotary connecting assembly 330. The bottom of the force guide rod 323 is provided with one or more second pin holes 324. At least one second pin hole 324 is provided adjacent to an end, away from the positioning tail rod 321, of the force guide rod 323, and the second pin hole 324 is in fit with the locking pin 314.
The rotary connecting assembly 330 is configured to connect the positioning tail rod 321 and the force guide rod 323. The rotary connecting assembly 330 preferably is a hinge shaft, which has an axial direction perpendicular to the water surface.
When the force guide rod 323 is rotated to have the same the length direction as the positioning tail rod 321, seven eighth of the own length of the force guide rod 323 can be stuffed into the storage cavity 311.
An end, away from the positioning tail rod 321, of the force guide rod 3232 is rotatably connected to the tail of the towing vessel 200.
In the actual use of the floating object cleanup device in the embodiment of the present disclosure, when the position of the cleaned-up river near the shore is a shoal, as shown in

Different connecting columns 333 have different size.
When the connecting columns 333 are located in the storage cavity 311, all the connecting columns 333 are nested together. The connecting columns 333, after leaving the storage cavity 311, naturally stretch to form a rod shape under the influence of the gravity of the force guide rod 323 and the gravity of the connecting columns 333. The bottom flange 335 of one connecting column 333 is abutted against the top flange 334 of the adjacent connecting column 333 to prevent the adjacent connecting columns from being separated from each other. When the connecting columns 333 need to be placed in the storage cavity 311 again, the connecting columns 333 can be manually nested together after the intercepting arm 300 is disassembled.
