Description

Technical Field

[0001] This invention relates to the field of environmental protection equipment technology, and in particular to a floating debris cleaning device. Background Technology

[0002] With societal development, the amount of floating debris on scenic waterways and urban and rural rivers is increasing, seriously affecting people's daily lives. Currently, most of the floating debris on these small bodies of water is removed using traditional manual methods, which are not only inefficient and ineffective but also labor-intensive. To address this, the inventor independently developed a floating debris removal vessel in invention patent ZL201410606202.0. Although this vessel significantly improves the efficiency of debris removal, the inventor found that while the pull-up boat and interceptor arm create a large water surface collection opening, greatly improving the collection efficiency, the problem of storing these components when they are not needed remains very challenging.

[0003] To solve the above-mentioned technical problems, the inventors further upgraded the floating debris cleaning vessel in invention patent No. ZL202211146804.3. The collection vessel is equipped with a pull boat storage device near the stern, so that the pull boat is placed in the pull boat storage device when not in operation, and the interception arm is set close to the side wall of the collection vessel.

[0004] However, in actual use, it was found that the above-mentioned method of fixing the puller boat to keep the interceptor arm close to the side of the collection boat has certain shortcomings in the positioning of the interceptor arm: because the interceptor arm is long and has a certain degree of deflection, fixing only the end close to the puller boat cannot ensure that the interceptor arm is close to the side of the collection boat (there will be sagging and the non-fixed end will move away from the side of the collection boat under the action of water flow); it causes great interference to the operation of the cleaning boat in the non-cleaning state (when the cleaning boat is adjusted from semi-submersible mode to normal mode) (affecting the speed and endurance of the cleaning boat). Summary of the Invention

[0005] This application provides a floating debris cleaning device that solves the technical problem that existing floating debris cleaning devices have relatively poor positioning effect on the interceptor arm when not cleaning, which can easily lead to the interceptor arm's presence seriously affecting the speed and endurance of the cleaning vessel. The device enables the floating debris cleaning device to conveniently store and position the interceptor arm when it is not in use, thus minimizing the interference caused by the presence of the interceptor arm to navigation.

[0006] This application provides a floating debris removal device, including a collection vessel, two pull boats with built-in propulsion systems, and two intercepting arms; the collection vessel is equipped with a control module for controlling the pull boats; the collection vessel and the two pull boats are connected together by the two intercepting arms; the stern of the collection vessel is equipped with two pull boat storage devices.

[0007] Both sides of the collection vessel are equipped with interceptor arm tightening components and support arm components;

[0009] The rotating shaft sleeve is fixed to the side of the collection vessel near the top by positioning blocks, and there are multiple of them; the distance between the rotating shaft sleeve and the side of the collection vessel is 1 to 1.3 times the width of the interceptor arm;

[0010] The rotating shaft passes through all the rotating shaft sleeves located on one side of the collection vessel, and an elastic element is positioned at the contact point between the rotating shaft and the rotating shaft sleeve.

[0011] The tightening arm is rod-shaped or plate-shaped, with its top end fixed to the bottom of the rotating shaft;

[0012] The support arm is an L-shaped plate that is fixed to the side wall of the collection vessel and located below the tightening arm; there are one or more support arms on one side of the collection vessel.

[0013] Furthermore, the support arm includes a load-bearing plate and a barrier plate;

[0014] The support plate is horizontally arranged, with a flat top surface and a width of 1.1 to 1.5 times the width of the interceptor arm, and is fixed to the side wall of the collection vessel.

[0015] The barrier plate is vertically installed, fixed above the support plate and positioned away from the edge of the collection vessel, to prevent the interceptor arm from sliding down the support plate.

[0016] Furthermore, the interceptor arm tightening assembly is also equipped with an auxiliary rod, which is a rigid rod, and the rotating shaft is provided with one or more holes into which the auxiliary rod can be inserted.

[0017] Preferably, the interceptor arm includes a base arm and an extension arm;

[0023] The positioning tail rod is a rigid straight rod with a length of 20 cm or more. The bottom is provided with a first pin hole that matches the locking pin. The end of the positioning tail rod that is close to the storage cavity is always located inside the storage cavity.

[0024] The guide rod is a rigid straight rod with a length of 0.5 to 0.7 times that of the base arm. One end is rotatably connected to the end of the positioning tail rod away from the storage cavity via a rotating connection assembly.

[0025] The bottom of the guide rod is provided with one or more second pin holes;

[0026] At least one second pin hole is provided near the end of the guide rod away from the positioning tail rod, and the second pin hole matches the locking pin;

[0027] The end of the guide rod away from the positioning tail rod is rotatably connected to the stern of the puller boat.

[0028] Preferably, the rotating connection assembly includes a first plate, a second plate, and a plurality of connecting posts;

[0029] Both the first plate and the second plate are horizontally arranged rigid plates, which serve to support the connecting column and are respectively fixed to the inner wall near the top of the positioning tail rod and the inner wall near the bottom of the guide rod.

[0030] The connecting post is located between the first plate and the second plate, with the top of one connecting post fixed to the first plate and the bottom of the other connecting post fixed to the second plate.

[0031] The connecting column is a hollow cylinder with an open bottom, and its axial direction is perpendicular to the thickness direction of the first plate and the second plate.

[0032] The outer side wall of the connecting column has an annular top flange near the top edge, and the inner side wall of the connecting column has an annular bottom flange near the bottom edge.

[0033] Different connecting columns are of different sizes. When the connecting columns are in the storage cavity, all the connecting columns are nested together and stacked together. When the connecting columns are removed from the storage cavity, they naturally extend into a rod shape under the influence of the gravity of the guide rod and their own gravity. At this time, the bottom flange and top flange of the adjacent connecting columns abut together to prevent the adjacent connecting columns from separating from each other.

[0034] Preferably, a connecting assembly block is fixed to the end of the guide rod away from the positioning tail rod;

[0035] The pull-out vessel is equipped with a support body and a telescopic positioning rod;

[0036] The support body is a plate-shaped, rod-shaped, or frame structure, which serves to support and fix the telescopic positioning rod.

[0042] Preferably, the locking pin is an electric pin with a compression spring fixed to its top, and an insertion block is fixed to the top of the compression spring. The insertion block is a cylindrical block with a hemispherical top, arranged longitudinally.

[0043] Each connecting column has an adsorption magnet on its inner top. The adsorption magnet is an electromagnet. When energized, all the adsorption magnets are attracted and fixed together.

[0044] Preferably, a support column is fixed at the end of the base arm away from the collection vessel. The support column includes a fixed column and a sliding column. The sliding column is coaxial with the fixed column and is slidably positioned on the fixed column. A compression spring is positioned between the two.

[0045] The fixed column is also equipped with a touch switch at the end near the sliding column. When the sliding column is pressed to overcome the elastic force and press the touch switch, the signal of the touch switch is transmitted to the control module. The control module controls the pull boat corresponding to the touch switch to move forward quickly once, increasing the angle between the base arm and the extension arm.

[0046] A column positioning frame is fixed on the sliding column, and a buffer column is positioned on the column positioning frame.

[0047] The column positioning frame is a U-shaped frame;

[0048] The buffer column is a rubber cylinder that is rotatably connected to the column positioning frame around its own axis and is arranged longitudinally.

[0049] During the clearing process, the buffer column will contact the obstacle before the base arm.

[0050] Preferably, one side of the pull vessel is provided with a splicing assembly, and the splicing assembly on the two pull vessels is arranged opposite to each other;

[0051] The splicing assembly includes a sliding block and a sliding guide rail;

[0052] The sliding guide rail is a straight guide rail, fixed to one side of the pull vessel and with its length direction in the same direction as the length direction of the pull vessel; the two sliding guide rails are parallel to each other;

[0053] The sliding block is slidably positioned on the sliding guide rail, and a combination buckle and a combination magnet are provided on its surface away from the sliding guide rail; the combination buckle is an electric buckle, and the combination magnet is an electromagnet; the combination buckle and the combination magnet are used to fix the two sliding blocks together.

[0054] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0055] By adding an interceptor arm tightening component and a support arm component to the side wall of the collection vessel, the interceptor arm is easily placed on the support arm component using its buoyancy, and then clamped and squeezed by the interceptor arm tightening component to fix the interceptor arm. This effectively solves the technical problem in the prior art where the positioning effect of the interceptor arm in the non-cleaning state of the floating debris cleaning device is relatively poor, which easily leads to the presence of the interceptor arm seriously affecting the speed and endurance of the cleaning vessel. As a result, the floating debris cleaning device can conveniently store and position the interceptor arm when it is not in use, so that the presence of the interceptor arm causes less interference to navigation.

[0078] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to limit the invention; the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0079] Example 1

[0080] like Figures 1 to 4 As shown, the floating debris removal device of this application includes a collection vessel 100, two pull boats 200 with built-in power systems, and two intercepting arms 300. The collection vessel 100 is equipped with a control module for controlling the pull boats 200. The collection vessel 100 and the two pull boats 200 are connected together by the two intercepting arms 300. The intercepting arms 300 float on the water surface when removing floating debris. The stern of the collection vessel 100 is equipped with two pull boat storage devices 140, which are bin or box structures, respectively located near the two sides of the collection vessel 100. The pull boats 200 are placed in the pull boat storage devices 140 when not in operation. The above structure is prior art and will not be described in detail here.

[0081] Both sides of the collection vessel 100 are provided with an interceptor arm tightening assembly 110 and a support arm 120; the interceptor arm tightening assembly 110 clamps and fixes the interceptor arm 300 to the side of the collection vessel 100 by applying pressure to the interceptor arm 300; the support arm 120 is plate-shaped and is used to support the interceptor arm 300.

[0082] The interceptor arm tightening assembly 110 includes a rotating sleeve 111, a positioning block 112, a rotating shaft 113, and a tightening arm 114;

[0083] The rotating shaft sleeve 111 is fixed to the side of the collection vessel 100 near the top by the positioning block 112, and there are multiple of them; the distance between the rotating shaft sleeve 111 and the side of the collection vessel 100 is 1 to 1.3 times the width of the intercepting arm 300; the axial direction of the rotating shaft sleeve 111 is the same as or approximately the same as the length direction of the collection vessel 100.

[0084] The rotating shaft 113 is a rigid straight rod that passes through all the rotating shaft sleeves 111 located on one side of the collection vessel 100. An elastic element is positioned at the contact position between the rotating shaft 113 and the rotating shaft sleeve 111. The elastic element is preferably a leaf spring or a torsion spring. The elastic element is used to accumulate and release elastic potential energy to assist the tightening arm 114 in clamping and fixing the intercepting arm 300.

[0085] The tightening arm 114 is rod-shaped, plate-shaped, etc., with its top end fixed to the bottom of the rotating shaft 113 for clamping the intercepting arm 300. Under normal conditions, the tightening arm 114 is in an inclined state due to the presence of the elastic element, with its bottom end closer to the side of the collection vessel 100 than its top end. When clamping the intercepting arm 300, the tightening arm 114 abuts against the intercepting arm 300.

[0086] When it is necessary to clamp the interceptor arm 300, first rotate the tightening arm 114 to allow the elastic element to accumulate elastic potential energy. When the interceptor arm 300 is placed between the tightening arm 114 and the collection vessel 100, the tightening arm 114 is lowered.

[0087] The support arm 120 is an L-shaped plate fixed to the side wall of the collection vessel 100; there are one or more support arms 120 on one side of the collection vessel 100; the opening of the support arm 120 faces the collection vessel 100; further, the support arm 120 includes a support plate and a barrier plate; the support plate is horizontally arranged, the top surface is flat, and the width is 1.1 to 1.5 times the width of the interceptor arm 300, and it is fixed to the side wall of the collection vessel 100; the barrier plate is vertically arranged, fixed above the support plate and located away from the edge of the collection vessel 100, and is used to prevent the interceptor arm 300 from sliding down the support plate.

[0088] In actual use, after the crew removes the interceptor arm 300 from the collection vessel 100 while the vessel is in semi-submersible mode, they first lift the tightening arm 114, and then insert the floating interceptor arm 300 between the tightening arm 114 and the collection vessel 100 by pulling and pushing; then they lower the tightening arm 114; the pressure applied to the interceptor arm 300 by the interceptor arm tightening assembly 110 will cause the interceptor arm 300 to move to the side of the collection vessel; after the cleaning vessel is adjusted from semi-submersible mode to normal mode, the interceptor arm 300 will naturally rest on the support arm 120 due to the loss of buoyancy (affected by its own weight).

[0089] Furthermore, the interceptor arm tightening assembly 110 is also equipped with an auxiliary rod 115, which is a rigid rod. The rotating shaft 113 is provided with one or more holes into which the auxiliary rod 115 can be inserted. In use, the auxiliary rod 115 can be inserted into the holes on the rotating shaft 113 to rotate the rotating shaft 113.

[0090] Preferably, for the purpose of saving effort, the hole through which the auxiliary rod 115 can be inserted extends into the tightening arm 114.

[0091] Furthermore, the tail ends of the two pull-boat storage devices 140 on the collection boat 100 are connected and fixed together by a protective rod 130 to form a propeller protection zone to prevent the collection boat propeller from being damaged by foreign objects; the protective rod 130 is a rigid rod or a rubber rod.

[0092] The technical solutions described in the embodiments of this application above have at least the following technical effects or advantages:

[0093] This invention solves the technical problem that existing floating debris removal devices have relatively poor positioning effect on the interceptor arm when not in use, which can easily lead to the interceptor arm's presence seriously affecting the speed and endurance of the cleaning vessel. It enables the floating debris removal device to conveniently store and position the interceptor arm when it is not in use, thus minimizing the interference caused by the presence of the interceptor arm to navigation.

[0094] Example 2

[0095] Considering the limitations of the floating debris cleaning device in the above embodiments, which, due to its structure, requires the minimum navigation depth of the tow barge 200 to effectively clean floating debris in shallow waters near the shore, the device is less effective at clearing debris. To further improve the practicality, maneuverability, and applicability of this application, overcome these limitations, and enable the floating debris cleaning device to efficiently clean floating debris in shallow waters near the shore, thereby improving the cleaning effect and preventing damage to the tow barge 200, this application optimizes and improves the structure of the interceptor arm 300 based on the above embodiments. Specifically:

[0096] like Figures 5 to 8 As shown, the interceptor arm 300 includes a base arm 310 and an extension arm 320;

[0097] The base arm 310 is a rigid strip with a rectangular, elliptical, or figure-eight shaped cross-section, floating on the water surface. A storage cavity 311 is located near the bottom of the base arm 310. In the cleanup state, the storage cavity 311 remains underwater. The storage cavity 311 stores the extension arm 320, and its length is the same as that of the base arm 310. One end of the base arm 310 is attached to the collection vessel 100, and a locking pin 314 is located on the bottom surface near the other end to restrict the movement of the extension arm 320. The locking pin 314 can be manual or electric.

[0098] The extension arm 320 is stored in the storage cavity 311 when not in use, and includes a positioning tail rod 321, a guide rod 323 and a rotating connection assembly 330.

[0099] The positioning tail rod 321 is a rigid straight rod with a length greater than or equal to 20 centimeters. The bottom is provided with a first pin hole 322 that matches the locking pin 314. The end of the positioning tail rod 321 that is close to the storage cavity 311 is always located inside the storage cavity 311.

[0100] The guide rod 323 is a rigid straight rod with a length of 0.5 to 0.7 times that of the base arm 310. One end is rotatably connected to the end of the positioning tail rod 321 away from the storage cavity 311 via a rotating connection assembly 330. The bottom of the guide rod 323 is provided with one or more second pin holes 324. At least one second pin hole 324 is provided near the end of the guide rod 323 away from the positioning tail rod 321, and the second pin hole 324 matches the locking pin 314.

[0101] The rotating connection assembly 330 is used to connect the positioning tail rod 321 and the guide rod 323, and is preferably a hinge shaft, the axis of which is perpendicular to the water surface;

[0102] When the guide rod 323 rotates to the same length direction as the positioning tail rod 321, it can insert more than seven-eighths of its own length into the storage cavity 311.

[0103] The end of the guide rod 323 away from the positioning tail rod 321 is rotatably connected to the stern of the pull boat 200.

[0104] In actual use, when the floating debris removal device of this application embodiment is in a shallow area near the bank of the river being cleaned, such as... Figure 5As shown, the crew can control the locking pin 314 to be pulled out of the second pin hole 324, and then pull the extension arm 320 out of the base arm 310 by the pull boat 200; then control the locking pin 314 to cooperate with the first pin hole 322 to fix the positioning tail rod 321; then control the collection boat 100 and the pull boat 200 to work together to bend the interception arm 300 into a V shape, and use the extension arm 320 to transmit the force from the pull boat 200 to control the opening angle of the base arm 310 to adapt to different river positions; when there are no shallows near the bank of the cleared river, control the locking pin 314 to be pulled out, adjust the angle between the base arm 310 and the extension arm 320, and finally reinstall the extension arm 320 into the base arm 310 by controlling the difference between the travel speed of the collection boat 100 and the travel speed of the pull boat 200.

[0105] Preferably, in order to reduce the impact of pulling out the extension arm 320 on the buoyancy of the base arm 310, both the positioning tail rod 321 and the guide rod 323 are rigid tubes.

[0106] Preferably, the guide rod 323 is provided with a plurality of water-permeable holes 325, and the water-permeable holes 325 are through holes.

[0107] Preferably, to reduce the impact of the guide rod 323 on the cleaning of floating objects, the guide rod 323 is positioned at a deeper water depth, reducing its obstruction of floating objects; the rotating connection assembly 330 includes a first plate 331, a second plate 332, and multiple connecting posts 333; the first plate 331 and the second plate 332 are both horizontally arranged rigid plates, each serving to support the connecting posts 333, and are respectively fixed to the inner wall near the top of the positioning tail rod 321 and the inner wall near the bottom of the guide rod 323; the connecting posts 333 are located between the first plate 331 and the second plate 332, with the top of one connecting post 333 fixed to the first plate 331 and the bottom of the other connecting post 333 fixed to the second plate 332; the connecting post 333 is a hollow cylinder with an open bottom, axially perpendicular to... The thickness directions of the first plate 331 and the second plate 332 are perpendicular. An annular top flange 334 is provided on the outer side wall of the connecting column 333 near the top edge, and an annular bottom flange 335 is provided on the inner side wall of the connecting column 333 near the bottom edge. The connecting columns 333 are of different sizes. When the connecting columns 333 are located in the storage cavity 311, all the connecting columns 333 are nested together and stacked together. When the connecting columns 333 are removed from the storage cavity 311, they naturally extend into a rod shape under the influence of the gravity of the guide rod 323 and their own gravity. At this time, the bottom flange 335 and the top flange 334 of the adjacent connecting columns 333 abut together to prevent the adjacent connecting columns 333 from separating from each other. When it is necessary to put the connecting columns 333 back into the storage cavity 311, the intercepting arm 300 can be removed and the connecting columns 333 can be stacked together manually.

[0108] To further reduce the impact of the guide rod 323 on the removal of floating debris, such as Figure 13 As shown, a connecting assembly block 326 is fixed to the end of the guide rod 323 away from the positioning tail rod 321; a support body 210 and a telescopic positioning rod 220 are fixed on the pull boat 200; the support body 210 is a plate-shaped, rod-shaped, or frame structure, which serves to support and fix the telescopic positioning rod 220; the telescopic positioning rod 220 is a longitudinally arranged electric telescopic rod, with its top fixed to the support body 210 and its bottom inserted into the water; the connecting assembly block 326 is rotatably connected to the bottom of the telescopic positioning rod 220; in use, the water depth where the guide rod 323 is located can be controlled by controlling the extension and retraction of the telescopic positioning rod 220.

[0109] Furthermore, the base arm 310 is provided with a mounting groove 312 near the collection vessel 100. The mounting groove 312 is a long, straight groove, and the base arm 310 is attached to the collection vessel 100 through the mounting groove 312.

[0110] Furthermore, in order to facilitate the retraction of the extension arm 320 into the intercepting arm 300, a trumpet-shaped guide plate 313 is provided at the opening of the storage cavity 311.

[0111] Preferably, in order to increase the wear resistance of the interception arm 300 and extend its service life, the end of the base arm 310 away from the collection vessel 100 is covered with sheet metal.

[0112] Preferably, in order to increase the wear resistance of the interception arm 300, reduce impact damage and wear during use, and extend its service life, a column positioning frame 316 is fixed to the end of the base arm 310 away from the collection vessel 100, and a buffer column 315 is positioned on the column positioning frame 316; the column positioning frame 316 is a U-shaped frame; the buffer column 315 is a rubber cylinder, which is rotatably connected to the column positioning frame 316 around its own axis and is arranged longitudinally; during the cleaning process, the buffer column 315 will contact the obstacle before the base arm 310.

[0113] To further improve the practicality and ease of use of this application, and reduce the labor intensity of its use; such as Figure 9 As shown, the locking pin 314 is an electric pin with a compression spring fixed to its top. An insertion block 319 is fixed to the top of the compression spring. The insertion block 319 is a cylindrical block with a hemispherical top, arranged longitudinally. Figure 10 , Figure 11 and Figure 12As shown, each connecting column 333 is equipped with an adsorption magnet 336 on its inner top. The adsorption magnet 336 is an electromagnet. When energized, all the adsorption magnets 336 are attracted and fixed together. When it is necessary to store or remove the guide rod 323, it can be achieved by using the locking pin 314 in conjunction with the adsorption magnet 336, the collection boat 100 and the pull boat 200.

[0114] To further reduce impact damage and wear during the use of the base arm 310 and extend its service life, such as Figure 16 As shown, a support column 317 is fixed to the end of the base arm 310 away from the collection vessel 100. The support column 317 includes a fixed column and a sliding column. The sliding column is coaxial with the fixed column and slidably positioned on the fixed column. A compression spring is positioned between the two, which gives the support column 317 a tendency to extend. A touch switch 318 is also provided at the end of the fixed column near the sliding column. When the sliding column is pressed against the spring force and the touch switch 318 is pressed, the signal of the touch switch 318 is transmitted to the control module. The control module controls the... The trigger switch 318 causes the pull boat 200 to move forward quickly once, increasing the angle between the base arm 310 and the extension arm 320. A column positioning frame 316 is fixed on the sliding column, and a buffer column 315 is positioned on the column positioning frame 316. The column positioning frame 316 is a U-shaped frame. The buffer column 315 is a rubber cylinder that rotates around its own axis and is connected to the column positioning frame 316, and is set longitudinally. During the cleaning process, the buffer column 315 will contact the obstacle before the base arm 310.

[0115] Example 3

[0116] To facilitate the control of the towing vessel 200, the present application embodiment has made certain optimizations and improvements to the structure of the towing vessel 200 based on the above embodiments, specifically as follows:

[0117] like Figure 13 , Figure 14 and Figure 15 As shown, a splicing assembly 230 is provided on one side of the towing vessel 200, and the splicing assembly 230s on the two towing vessels 200 are arranged opposite to each other;

[0118] The splicing assembly 230 includes a sliding block 231 and a sliding guide rail 232;

[0119] The sliding guide rail 232 is a straight guide rail, fixed to one side of the pull boat 200 and its length direction is the same as the length direction of the pull boat 200; the two sliding guide rails 232 are parallel to each other;

[0120] The sliding block 231 is slidably positioned on the sliding guide rail 232, and a combination buckle 233 and a combination magnet 234 are provided on its surface away from the sliding guide rail 232; the combination buckle 233 is an electric buckle, and the combination magnet 234 is an electromagnet; the combination buckle 233 and the combination magnet 234 are used to fix the two sliding blocks 231 together.

[0121] When clearing relatively straight waterways, two 200-ton tractor boats can be combined together, and then separated when a turn is needed.

[0122] Preferably, in order to achieve the goal of energy saving, such as Figure 17 As shown, the guide rod 323 is an elliptical rod, and the elliptical structure experiences relatively less resistance in water.

[0123] Preferably, to facilitate the retrieval of the guide rod 323 and reduce its bending in water due to its own deflection, such as Figure 18 As shown, the guide rod 323 is heavier at both ends and lighter in the middle.

[0124] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. For those skilled in the art, the present invention can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
