Technical Field

[0001] The invention belongs to the technical field of ship cleaning, in particular to a device for cleaning attachments on the bottom of a ship. Background Art

[0002] The attachments on the bottom of the ship, usually called biofouling, refer to the biological communities attached to the bottom, hull, propeller and other surfaces of the ship. These biological communities include various microorganisms, algae, shellfish and crustaceans.

[0012] Preferably, the connecting frame controls the water flow size by driving the third buffer component and the fourth buffer component to move, thereby driving the docking plate to move. The third buffer component includes a fourth connecting block and a third spring.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The present invention cooperates with structures such as a shovel seat, a movable plate and a driving mechanism, and drives a connecting disc to rotate through a driving motor. The connecting column on the top of the connecting disc drives the movable block limited by the shovel seat to move back and forth, thereby driving the movable plate connected to the movable block to move back and forth, and cooperates with the shovel seat to form a saw-like structure to shovel away the attachments on the bottom of the ship, which can effectively improve the cleaning effect of the attachments. When the teeth on the movable plate cover the teeth on the surface of the shovel seat, the tooth gap on the shovel seat is completely exposed, and the water flow sprayed by the water spray mechanism is directed to the tooth gap on the shovel seat, so that the high-pressure water flow hits the end of the attachment that adheres to the bottom of the ship, so that the attachment is loosened or even falls off, thereby facilitating the shovel seat and the movable plate to cooperate to clean the attachment.

[0017] 2. In the present invention, when the first hole and the second hole are gradually staggered, the water flow through the two holes gradually becomes less than when they are superimposed. At this time, the bottom of the shovel seat is flushed. During the flushing process, since the shovel seat and the movable plate have cooperated to clear the large attachments at this location, only some residual attachments need to be cleaned. Therefore, a large amount of water flow is not required to ensure the cleaning effect, saving water resources. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] like Figures 1 to 9 As shown, the present invention provides a ship bottom attachment cleaning device, comprising a connecting rod 1 and a shovel seat 2, the shovel seat 2 is installed on the connecting rod 1, and also comprises a movable plate 3, the movable plate 3 is slidably connected to the inside of the shovel seat 2 and extends to the inclined surface of the shovel seat 2; a driving mechanism 4, the driving mechanism 4 is installed in the shovel seat 2 and drives the movable plate 3 to move back and forth, the driving mechanism 4 comprises a driving motor 401, a connecting disc 402, a connecting column 403 and a movable block 404, the driving motor 401 is installed in the shovel seat 2, the connecting disc 402 is installed on the output shaft of the driving motor 401, and the connecting column 403 is installed on the output shaft of the driving motor 401. Installed at one end of the top of the connecting disc 402, the movable block 404 is sleeved on the surface of the connecting column 403 and is slidably connected to the inside of the shovel seat 2; a water storage mechanism 5, the water storage mechanism 5 is arranged on the inner wall of the lower end of the connecting rod 1, and is used to store cleaning water; a guide mechanism 6, the guide mechanism 6 is arranged on one side of the water storage mechanism 5; a water spraying mechanism 7, the water spraying mechanism 7 is connected to the water storage mechanism 5 and the guide mechanism 6, and the water spraying mechanism 7 is used to wash the bottom of the ship; a connecting frame 8, the connecting frame 8 is installed on the driving mechanism 4; a water injection pipe 11, the water injection pipe 11 passes through the shovel seat 2 and extends to the inside of the water storage mechanism 5 for water injection.

[0030] The connecting disc 402 is driven to rotate by the driving motor 401, and the connecting column 403 on the top of the connecting disc 402 drives the movable block 404 limited by the shovel seat 2 to move back and forth, thereby driving the movable plate 3 connected to the movable block 404 to move back and forth, and cooperates with the shovel seat 2 to form a saw-like structure to remove the attachments on the bottom of the ship, which can effectively improve the removal effect of the attachments. At the same time, during the back and forth movement of the movable block 404, it can drive the guide mechanism 6 to move, thereby changing the direction of the water flow sprayed by the water spray mechanism 7;

[0031] When the teeth on the movable plate 3 cover the teeth on the surface of the shovel seat 2, the tooth gap on the shovel seat 2 is completely exposed, and the water flow sprayed by the water spray mechanism 7 is directed to the tooth gap on the shovel seat 2, so that the high-pressure water flow hits the end of the attachment adhering to the bottom of the ship, so that the attachment is loosened or even falls off, thereby facilitating the shovel seat 2 and the movable plate 3 to cooperate in cleaning the attachment;

[0032] When the teeth on the movable plate 3 cover the tooth gaps on the surface of the shovel seat 2, the water flow sprayed by the water spray mechanism 7 is tilted toward the bottom of the shovel seat 2 to rinse the area where the attachments are removed, further improving the cleaning effect.

[0033] like Figure 6 and Figure 7 As shown, the guide mechanism 6 includes a connecting plate 601, a positioning column 602, a limiting plate 603, a first buffer assembly 604 and a second buffer assembly 605. The connecting plate 601 is slidably connected to the inside of the connecting rod 1 through the first buffer assembly 604 and the limiting plate 603. The positioning column 602 is fixedly mounted on the surface of the connecting plate 601. The second buffer assembly 605 is mounted on the side of the connecting plate 601 away from the limiting plate 603. An arc groove is provided on the surface of the limiting plate 603. The positioning column 602 moves inside the arc groove, and the arc groove is high in the middle and low at both ends.

[0034] The arc groove set on the surface of the limit plate 603 can cooperate with the positioning column 602 to realize the back and forth movement of the connecting plate 601 in height. When the connecting plate 601 is at the highest point, the water spraying mechanism 7 driven by the connecting plate 601 points to the tooth gap on the shovel seat 2. When the connecting plate 601 is at the lowest point, the water spraying mechanism 7 points to the bottom of the shovel seat 2. The first buffer component 604 set can position the connecting plate 601.

[0035] like Figure 7 As shown, the first buffer assembly 604 is symmetrically arranged in two groups, and the first buffer assembly 604 includes a first connecting block 6041, a first spring 6042 and a second connecting block 6043. The first connecting block 6041 is fixedly connected to the connecting plate 601, and the second connecting block 6043 is fixedly connected to the inner wall of the shovel seat 2. The first spring 6042 is fixedly installed on the opposite surfaces of the first connecting block 6041 and the second connecting block 6043.

[0036] The first connecting block 6041 and the second connecting block 6043 are connected by a first spring 6042 , and the first spring 6042 is elastic and can provide compensation when the connecting plate 601 moves up and down, thereby ensuring the stability of the position of the connecting plate 601 and further ensuring the stability of the water spraying direction of the water spraying mechanism 7 .

[0037] like Figure 8 As shown, the second buffer assembly 605 is symmetrically arranged in two groups. The second buffer assembly 605 includes a third connecting block 6051 and a second spring 6052. The third connecting block 6051 is installed on the surface of the connecting plate 601, and the third connecting block 6051 is elastically connected to the connecting frame 8 through the second spring 6052.

[0038] The second spring 6052 is elastic and cooperates with the first buffer assembly 604 to ensure the stability of the connecting plate 601 when it moves up and down, and can move in the length direction when driven by the connecting frame 8. The first spring 6042 cooperates with the second spring 6052 to reduce the moving distance of the connecting plate 601 in the length direction, thereby limiting the flushing angle of the water spray mechanism 7 and ensuring the optimal flushing range.

[0039] like Figure 6 As shown, the water spray mechanism 7 includes a first ball head 701, a telescopic tube 702 and a second ball head 703. The first ball head 701 is sleeved on the connecting plate 601, and the second ball head 703 is sleeved on the water storage mechanism 5. The first ball head 701 and the second ball head 703 are respectively fixed at both ends of the telescopic tube 702.

[0040] The first ball head 701 and the second ball head 703 cooperate to adjust the direction of the telescopic tube 702. The telescopic tube 702 can be extended and retracted. When the first ball head 701 is moved by the connecting plate 601, compensation can be made by the extension and retraction of the telescopic tube 702, thereby ensuring the rationality of the structure.

[0041] like Fig. 9 As shown, the water storage mechanism 5 includes a water storage tank 501, a partition plate 502 and a docking plate 503. The water storage tank 501 is fixedly installed on the inner wall at the bottom of the shovel seat 2, the partition plate 502 is fixedly installed inside the water storage tank 501, and the docking plate 503 is slidably connected to the inside of the water storage tank 501. The partition plate 502 fits with the docking plate 503. The ends of the shovel seat 2 and the movable plate 3 away from the connecting rod 1 are both toothed, and the teeth on the surfaces of the two are staggered. A first hole is opened on the surface of the water storage tank 501, and a second hole matched with the first hole is opened on the surface of the docking plate 503.

[0042] The water injection pipe 11 is provided to replenish the cleaning water inside the water storage tank 501. When the docking plate 503 is driven by the connecting frame 8 to slide along the length direction inside the water storage tank 501, the first hole and the second hole follow a motion trajectory of "stagger-overlap-stagger";

[0043] When the first hole and the second hole overlap, the water flow through the telescopic tube 702 is the largest, and at this time, the teeth on the movable plate 3 cover the tooth surface on the shovel seat 2, and the tooth gap on the shovel seat 2 is exposed. The water flow sprayed from the telescopic tube 702 impacts the bonding point between the attachment in front and the ship along the tooth gap on the shovel seat 2, promoting the shedding of the attachment;

[0044] When the first hole and the second hole are gradually staggered, the water flow through the two holes gradually becomes less than when they are superimposed. At this time, the bottom of the shovel seat 2 is flushed. During the flushing process, since the shovel seat 2 and the movable plate 3 have cooperated to clear the large attachments at this location, only some residual attachments need to be cleaned. Therefore, the cleaning effect can be guaranteed without a large amount of water flow, saving water resources.

[0045] like Figures 6 to 8 As shown, the connecting frame 8 controls the water flow size by driving the third buffer component 9 and the fourth buffer component 10 to move, thereby driving the docking plate 503 to move. The third buffer component 9 includes a fourth connecting block 901 and a third spring 902. The fourth connecting block 901 is fixedly installed on the top of the water storage tank 501 and is symmetrically distributed. The fourth connecting block 901 is elastically connected to the docking plate 503 through the third spring 902. The fourth buffer component 10 includes a fifth connecting block 1001 and a fourth spring 1002. The fifth connecting block 1001 is fixedly installed on the top of the docking plate 503. The fifth connecting block 1001 is elastically connected to the connecting frame 8 through the fourth spring 1002.

[0046] The moving distance of the docking plate 503 is not as large as the moving distance of the connecting frame 8. Through the expansion and contraction amount of the third spring 902 and the fourth spring 1002, the back and forth movement of the connecting frame 8 can be coordinated to achieve the synchronous back and forth movement of the docking plate 503 and the connecting frame 8. The movement amounts of the two are different, thereby ensuring the rationality of the structure.

[0047] The working principle and use process of the present invention:

[0048] When in use, the water injection pipe 11 is connected to the water pipe, and the connecting rod 1 is carried by hand to stick the shovel seat 2 to the bottom of the ship, and the driving motor 401 is started to drive the connecting disc 402 to rotate, and the connecting column 403 is driven by the connecting disc 402 to rotate around the axis of the connecting disc 402, thereby driving the movable block 404 limited by the shovel seat 2 to achieve reciprocating motion, and then driving the movable plate 3 to move back and forth on the surface of the shovel seat 2, forming a saw-like structure to remove the attachments;

[0049] The reciprocating motion of the movable block 404 synchronously drives the connecting frame 8 to reciprocate. During the movement, the connecting frame 8 drives the connecting plate 601 to reciprocate synchronously through the cooperation of the first buffer component 604 and the second buffer component 605, so as to change the angle of the telescopic tube 702 in the horizontal direction. At the same time, when the connecting plate 601 is driven to reciprocate by the connecting frame 8, the limiting plate 603 cooperates with the positioning column 602 fixed on the connecting plate 601, so that the connecting plate 601 synchronously reciprocates in its height direction, so as to adjust the spray range of the telescopic tube 702.

[0050] The reciprocating motion of the connecting frame 8 synchronously drives the docking plate 503 to reciprocate through the fourth buffer assembly 10 and the third buffer assembly 9. During the reciprocating process of the docking plate 503, the first hole on the partition plate 502 and the second hole on the docking plate 503 realize a "staggered-overlapped-staggered" state. When the first hole and the second hole are overlapped, the water flow through the telescopic tube 702 is the largest, and at this time, the teeth on the movable plate 3 cover the tooth surface on the shovel seat 2, and the tooth gap on the shovel seat 2 is exposed. The water flow sprayed from the telescopic tube 702 impacts the bonding point between the front attachment and the ship along the tooth gap on the shovel seat 2, promoting the shedding of the attachment. When the first hole and the second hole are gradually offset, the water flow through the two gradually decreases compared to when they are overlapped. At this time, the bottom of the shovel seat 2 is flushed.
