In the above ship with the auxiliary stabilizing device, the waterproof baffle has a chamfer.

Compared with the prior art, the ship has the following advantages:

1. the driving piece drives the first positioning sleeve to slide forwards, the first positioning sleeve drives the fin stabilizer push rod, and the fin stabilizer push rod drives the first sliding block to slide on the lower sliding groove, so that the first sliding block slides to the first spiral sliding groove from the first linear sliding groove. When the first sliding block slides on the first linear sliding groove, the fin stabilizer push rod and the fin stabilizer synchronously move forwards; after the first sliding block slides to the first spiral sliding groove from the first linear sliding groove, the fin stabilizer push rod and the fin stabilizer synchronously rotate when moving forwards, and the fin stabilizer rotates towards the outer side of the ship body. Therefore, the fin extends out of the fin notch, and the fin is far away from the ship body and forms a certain included angle with the ship body. After the anti-rolling fins on the left side and the right side of the ship body are opened, the stability of the ship body in the sailing process is effectively improved, and the shaking amplitude of the ship body is reduced.

2. When the first sliding block slides on the first spiral sliding groove, the synchronous rotating angle of the fin stabilizer push rod and the fin stabilizer is in direct proportion to the sliding distance of the first sliding block on the first spiral sliding groove. Namely, the longer the sliding distance of the first sliding block on the first spiral sliding groove is, the larger the synchronous rotating angle of the fin stabilizer push rod and the fin stabilizer is. Therefore, the sliding distance of the first sliding block on the first spiral sliding groove is adjusted, so that the included angle formed between the fin stabilizer and the ship body of the ship can be timely adjusted under different navigation speeds, storms and other environments, and the stability of the ship is effectively improved.

3. The first sliding block slides to the second linear sliding groove from the first spiral sliding groove, the fin stabilizer push rod and the fin stabilizer stop rotating, and an included angle formed between the fin stabilizer and the ship body is the largest. With the sliding of the first sliding block on the second linear sliding groove, an included angle formed between the fin stabilizer and the ship body is kept unchanged, and the fin stabilizer push rod and the fin stabilizer synchronously move forwards, namely the position of the fin stabilizer on the ship body can move forwards and backwards. When the fin is moved to the vicinity of the hull head, the lift force obtained by the fin promotes the lifting of the ship head and the reduction of the immersion depth, thereby reducing the total resistance suffered by the ship.

4. When the fin is retracted into the fin notch, the second slider is positioned on the third linear sliding groove under the action of the driving piece, and the waterproof baffle is positioned on the lower side of the waterproof baffle push rod and is accommodated in the waist-shaped shell. This structure will help accomodating stabilizer fin and waterproof baffle simultaneously, reduces stabilizer fin and waterproof baffle area.

When the driving mechanism is opened and closed, the driving piece drives the second sliding block to slide on the third linear sliding groove through the second positioning sleeve, so that the waterproof baffle push rod and the waterproof baffle synchronously move forward, and the waterproof baffle gradually extends out of the waist-shaped shell. After the second sliding block slides to the second spiral sliding groove from the third linear sliding groove, the waterproof baffle extends out of the waist-shaped shell. The waterproof baffle push rod moves forwards and is driven by the second sliding block to rotate, and the waterproof baffle push rod drives the waterproof baffle to rotate upwards, so that the waterproof baffle extends to the upper part of the ship body, water is prevented from splashing into the ship body, and the building and equipment in the ship are protected.

When the driving piece drives the second sliding block to move through the second positioning sleeve, the driving piece also drives the first sliding block to slide on the lower sliding groove through the first positioning sleeve, so that the fin stabilizer push rod and the waterproof baffle push rod synchronously move forwards, namely the fin stabilizer and the waterproof baffle synchronously extend out of the waist-shaped shell. When the waterproof baffle extends to the upper part of the ship body, the anti-rolling fins on the left side wall and the right side wall of the ship body are also opened, and the stability of the ship is improved.

Detailed Description

The following are specific embodiments of the present invention and are further described with reference to the drawings, but the present invention is not limited to these embodiments.

Referring to fig. 1 to 7, a vessel with an auxiliary stabilizing device includes a vessel 8, and: the ship comprises two waist-shaped shells 1 which are respectively arranged on the left side wall and the right side wall of a ship body 8, wherein each waist-shaped shell 1 comprises a body 2 which is fixedly arranged on the side wall of the ship body 8 in the front-back direction;

the lower tubular part 3 is fixedly arranged on the lower side edge of the body 2, a first opening 31 communicating the interior of the lower tubular part 3 with the interior of the body 2 is arranged at the joint of the lower tubular part 3 and the body 2, and a strip-shaped fin stabilizer gap 32 is formed in the front end of the lower tubular part 3; a lower chute is arranged on the inner wall of the lower tubular part 3, and the lower chute sequentially comprises a first linear chute 33 in a strip shape and a first spiral chute 34 in a spiral shape from inside to outside; the first linear chute 33 is parallel to the axis of the lower tubular part 3, and the first spiral chute 34 encircles the axis of the lower tubular part 3; the adjacent ends of the first spiral chute 34 and the first linear chute 33 are overlapped;

a fin stabilizer push rod 4, wherein the fin stabilizer push rod 4 is arranged in the lower tubular part 3 and is arranged on the lower chute in a sliding way through a first slide block 42; the fin stabilizer push rod 4 is rotatably connected with a first positioning sleeve 44, and the first positioning sleeve 44 is arranged in the lower tubular part 3 in a sliding manner; the fin stabilizer push rod 4 is fixedly provided with a fin stabilizer 41; a driving mechanism is arranged in the waist-shaped shell 1, the front and back movement direction of a driving piece of the driving mechanism is parallel to the axis of the fin stabilizer push rod 4, and the driving piece is fixedly connected with the first positioning sleeve 44 through a first connecting rod 54; when the fin pushrod 4 extends and retracts into the lower tubular portion 3, the fin 41 extends and retracts into the fin notch 32.

When the wind and waves are small and the cruising speed is low, the fin 41 is retracted into the fin notch 32 by the driving member, and the fin 41 is close to the hull 8, thereby reducing the resistance of the ship during cruising. The first slider 42 is now on the first linear guide 33.

When the wind and the wave are large and the shaking amplitude of the ship body 8 is large, the driving mechanism is turned on or turned off, the driving piece drives the first positioning sleeve 44 to slide forwards, the first positioning sleeve 44 drives the fin stabilizer push rod 4, the fin stabilizer push rod 4 drives the first sliding block 42 to slide on the lower sliding groove, and the first sliding block 42 slides to the first spiral sliding groove 34 from the first linear sliding groove 33. When the first slider 42 slides on the first linear chute 33, the fin stabilizer push rod 4 moves forward in synchronization with the fin stabilizer 41; after the first sliding block 42 slides from the first linear sliding groove 33 to the first spiral sliding groove 34, the fin stabilizer push rod 4 and the fin stabilizer 41 simultaneously rotate when moving forward synchronously, and the fin stabilizer 41 rotates to the outside of the hull 8. Thus, the fin 41 protrudes out of the fin notch 32, the fin 41 being away from the hull 8 and forming an angle with the hull 8. After the stabilizer fins 41 on the left side and the right side of the ship body 8 are opened, the stability of the ship body 8 in the sailing process is effectively improved, and the shaking amplitude of the ship body 8 is reduced.

Further, when the first slider 42 slides on the first screw sliding groove 34, the angle at which the fin push rod 4 and the fin 41 rotate in synchronization is proportional to the distance that the first slider 42 slides on the first screw sliding groove 34. That is, the longer the distance that the first slider 42 slides on the first screw sliding groove 34, the larger the angle at which the fin stabilizer push rod 4 and the fin stabilizer 41 rotate in synchronization. Therefore, the sliding distance of the first sliding block 42 on the first spiral chute 34 is adjusted, so that the included angle formed between the fin stabilizer 41 and the ship body 8 of the ship can be adjusted in time under different navigation speeds, storms and other environments, and the stability of the ship is effectively improved.

Further, the length of the first linear guide groove 33 is greater than the length of the fin cut 32.

When the first slider 42 slides to the overlapping position of the first linear chute 33 and the first spiral chute 34, the fin 41 just extends out of the fin notch 32. The fin cut-out 32 is for receiving the fin 41. When the fin stabilizer 41 retracts into the fin stabilizer notch 32, the fin stabilizer notch 32 has a limiting effect, so that the stability of the fin stabilizer 41 is improved, and the shaking of the fin stabilizer 41 is effectively reduced; when the fin stabilizer 41 extends out of the fin stabilizer notch 32, the fin stabilizer 41 rotates to the outer side of the ship body 8 under the driving of the fin stabilizer push rod 4, and the fin stabilizer 41 is opened, so that the stability of the ship is improved.

Further, a first annular positioning groove 441 is formed in the inner wall of the first positioning sleeve 44, a first annular positioning block 43 is fixedly arranged on the fin stabilizer push rod 4, and the first annular positioning block 43 is slidably arranged on the first annular positioning groove 441.

The first positioning sleeve 44 moves back and forth inside the lower tubular portion 3 under the action of the driving member; the first positioning sleeve 44 drives the fin stabilizer push rod 4 to move back and forth through the first annular positioning block 43; when the first slider 42 slides on the first spiral sliding groove 34, the first slider 42 drives the fin stabilizer push rod 4 and the fin stabilizer 41 to rotate, and the first annular positioning block 43 slides in the first annular positioning groove 441, that is, the fin stabilizer push rod 4 rotates relative to the first positioning sleeve 44.

The structure drives the fin stabilizer push rod 4 and the fin stabilizer 41 to rotate simultaneously when the driving piece moves back and forth, so that the number of driving elements is reduced, the volume of the waist-shaped shell 1 is effectively reduced, and the resistance generated by the waist-shaped shell 1 mounted on the ship body 8 is reduced.

Specifically, a second linear sliding groove 35 is formed in the inner wall of the lower tubular part 3, the second linear sliding groove 35 is located between the first spiral sliding groove 34 and the front end of the lower tubular part 3, the second linear sliding groove 35 is parallel to the first linear sliding groove 33, and the second linear sliding groove 35 is staggered with the first linear sliding groove 33; the second linear slide groove 35 coincides with the adjacent end of the first spiral slide groove 34.

When the first sliding block 42 slides from the first spiral sliding groove 34 to the second linear sliding groove 35, the fin stabilizer push rod 4 and the fin stabilizer 41 stop rotating, and the included angle formed between the fin stabilizer 41 and the ship body 8 is maximized. As the first slider 42 slides on the second linear sliding groove 35, the angle formed between the fin 41 and the hull 8 remains unchanged, and the fin push rod 4 moves forward in synchronization with the fin 41, i.e., the position of the fin 41 on the hull 8 can move back and forth. When the fin 41 is moved to the vicinity of the bow of the hull 1, the lift force obtained by the fin 41 causes the bow of the ship to be lifted and the immersion depth to be reduced, thereby reducing the total resistance to which the ship is subjected.

Specifically, the oval shell 1 further comprises an upper tubular part 6 fixedly arranged at the upper side edge of the body 2, a second opening 61 for communicating the inside of the upper tubular part 6 with the inside of the body 2 is arranged at the joint of the upper tubular part 6 and the body 2, an upper chute is arranged on the inner wall of the upper tubular part 6, and the upper chute sequentially comprises a third linear chute 62 and a spiral second spiral chute 63 from inside to outside; the third linear chute 62 is parallel to the axis of the upper tubular part 6, and the second spiral chute 63 surrounds the axis of the upper tubular part 6; the adjacent ends of the second spiral sliding chute 63 and the third linear sliding chute 62 are overlapped; a waterproof baffle push rod 7 is arranged in the upper tubular part 6, and the waterproof baffle push rod 7 is arranged on the upper sliding groove in a sliding manner through a second sliding block 74; the waterproof baffle push rod 7 is rotatably connected with a second positioning sleeve 72, and the second positioning sleeve 72 is arranged in the upper tubular part 6 in a sliding manner; the second positioning sleeve 72 is fixedly connected with the driving member through a second connecting rod 55.

When the fin 41 retracts into the fin notch 32, the second slider 74 is positioned on the third linear sliding groove 62 under the action of the driving member, the waterproof baffle 71 is positioned at the lower side of the waterproof baffle push rod 7, and the waterproof baffle 71 is accommodated in the kidney-shaped shell 1. This structure will help to house both the fin 41 and the waterproof dam 71, reducing the area occupied by the fin 41 and the waterproof dam 71.

When the driving mechanism is opened and closed, the driving piece drives the second slider 74 to slide on the third linear chute 62 through the second positioning sleeve 72, so that the waterproof baffle push rod 7 and the waterproof baffle 71 synchronously move forward, and the waterproof baffle 71 gradually extends out of the waist-shaped shell 1. After the second sliding block 74 slides from the third linear sliding groove 62 to the second spiral sliding groove 63, the waterproof baffle 71 extends out of the waist-shaped shell 1. Waterproof baffle push rod 7 moves forward and is still rotated by the drive of second slider 74 simultaneously, and waterproof baffle push rod 7 drives waterproof baffle 71 and upwards rotates to make waterproof baffle 71 extend to hull 8 top, avoid in the water splash to hull 8, protect last building and equipment in this boats and ships.

In the above process, while the driving member drives the second slider 74 to move through the second positioning sleeve 72, the driving member also drives the first slider 42 to slide on the lower chute through the first positioning sleeve 44, so that the fin push rod 4 and the waterproof baffle push rod 7 synchronously move forward, that is, the fin 41 and the waterproof baffle 71 synchronously extend out of the waist-shaped shell 1. When the waterproof baffle 71 extends above the hull 8, the fin stabilizers 41 on the left and right side walls of the hull 8 are also opened, thereby improving the stability of the ship.

Further, a second annular positioning groove 721 is formed in the inner wall of the second positioning sleeve 72, a second annular positioning block 73 is fixedly arranged on the waterproof baffle push rod 7, and the second annular positioning block 73 is slidably arranged on the second annular positioning groove 721.

Under the action of the driving member, the second positioning sleeve 72 moves back and forth in the upper tubular part 6; the second positioning sleeve 72 drives the waterproof baffle push rod 7 to move back and forth through a second annular positioning block 73; when the second slider 74 slides on the second spiral sliding groove 63, the second slider 74 drives the waterproof baffle push rod 7 and the waterproof baffle 71 to rotate, and the second annular positioning block 73 slides in the second annular positioning groove 721, that is, the waterproof baffle push rod 7 rotates relative to the second positioning sleeve 72.

In the above structure, the driving member drives the first positioning sleeve 44 and the second positioning sleeve 72 to move back and forth simultaneously. When the first slider 42 and the second slider 74 slide on the lower chute and the upper chute, respectively, the fin stabilizer push rod 4 and the water baffle push rod 7 synchronously move back and forth and synchronously rotate, and the structure effectively reduces the time for the fin stabilizer 41 and the water baffle 71 to extend out of the kidney-shaped shell 1.

Specifically, the first linear slide 33 is located directly below the third linear slide groove 62, and the overlapping portion of the first linear slide groove 33 and the first spiral slide groove 34 is located directly below the overlapping portion of the third linear slide groove 62 and the second spiral slide groove 63.

When the first sliding block 42 slides to the overlapping position of the first linear sliding groove 33 and the first spiral sliding groove 34, the second sliding block 63 also slides to the overlapping position of the third linear sliding groove 62 and the second spiral sliding groove 63, and at this time, the fin stabilizer 41 and the waterproof baffle 71 respectively and synchronously extend out of the fin notch 32 and the kidney-shaped shell 1, and the structure can avoid the occurrence of the blocking condition.

Specifically, the first spiral chute 34 and the second spiral chute 63 have the same pitch, and the length of the first spiral chute 34 is smaller than that of the second spiral chute 63.

The above structure makes the rotation angle of the waterproof baffle push rod 7 larger than that of the fin stabilizer push rod 41. Therefore, when the fin 41 is opened, that is, the first slider 42 slides on the second linear sliding groove 35, the second slider 74 also slides on the second spiral sliding groove 63, the waterproof baffle 71 also rotates upward around the waterproof baffle push rod 7 until the waterproof baffle 71 protrudes above the hull 8, the first slider 42 slides to the front end of the second linear sliding groove 35, and the fin 41 moves to the vicinity of the head of the hull 1.

Specifically, the driving mechanism comprises a positive and negative rotation motor 5 arranged on the body 2, the driving piece comprises a screw rod 51 and a sliding sleeve 53 in threaded connection with the screw rod 51, and an output shaft of the positive and negative rotation motor 5 is in transmission connection with the screw rod 51 through a reduction gear set 52; the axis of the screw rod 51 is parallel to the axis of the fin stabilizer push rod 4 and the waterproof baffle push rod 7; the sliding sleeve 53 is respectively fixedly connected with the first positioning sleeve 44 and the second positioning sleeve 72 through a first connecting rod 54 and a second connecting rod 55.

The forward and reverse rotation motor 5 rotates forward, the forward and reverse rotation motor 5 drives the screw rod 51 to rotate, the screw rod 51 drives the sliding sleeve 53 to move forward, and the sliding sleeve 53 synchronously drives the first positioning sleeve 44 and the second positioning sleeve 72 to move forward through the first connecting rod 54 and the second connecting rod 55. The first positioning sleeve 44 and the second positioning sleeve 72 respectively drive the fin stabilizer push rod 4 and the waterproof baffle push rod 7 to move forwards. When the first slider 42 and the second slider 74 pass through the first screw chute 34 and the second screw chute 63, respectively, the fin stabilizer push rod 4 and the waterproof barrier push rod 7 rotate synchronously, so that the fin stabilizer 41 is opened and the waterproof barrier 71 protrudes above the hull 8.

The forward and reverse rotation motor 5 rotates reversely, and the forward and reverse rotation motor 5 drives the sliding sleeve 53 to move backwards through the screw rod 51, so that the fin stabilizer 41 and the waterproof baffle 71 are respectively retracted into the fin stabilizer notch 32 and the waist-shaped shell 1.

Further, the ship body 8 is also provided with a controller 9 and a storage battery 91 electrically connected with the controller 9, and the controller 9 is electrically connected with the forward and reverse rotation motors 5 in the two kidney-shaped shells 1 through the storage battery 91. The controller 9 is a PLC controller.

The controller 9 sends electric signals to the two motors 5 at the same time, so that the two motors 5 are started or closed at the same time, and the operation is convenient.

Specifically, a horizontal through groove 711 is formed in the waterproof baffle 71 in a horizontally penetrating manner, two vertical through grooves 712 are formed in the waterproof baffle 71 in a vertically penetrating manner, and the two vertical through grooves 712 are respectively located near the edges of the two opposite sides of the waterproof baffle 71.

The transverse channel 711 and the two vertical channels 712 facilitate the crew's handrails when the flashing 71 extends out of the hull 8.

Specifically, the waterproof shutter 71 has a chamfer 713.

The provision of the chamfer 713 prevents accidental scratching by the crew when the flashing 71 extends beyond the hull 8. The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications or additions may be made to the described embodiments or alternatives may be employed by those skilled in the art without departing from the spirit or ambit of the invention as defined in the appended claims.
