Description

Technical Field

[0001] The invention relates to the field of stable platforms for ships, and in particular to an anti-swaying platform for ships. Background Art

[0002] The anti-sway platform for ships is a device or apparatus installed on the ship, which aims to reduce the swaying of the ship caused by waves, wind and other factors during navigation. The main purpose of the existing shipboard stabilizing platform is to place medical equipment or perform medical treatment on the stable platform and ensure stability during the process.

[0003] Existing ship stabilization devices usually use a hydraulic control system, which monitors the degree of the ship's shaking and drives the platform through driving devices such as hydraulic rods to keep the platform balanced relative to the ship. However, driving systems such as hydraulic controls are prone to damage during long-term use, causing the platform's stabilization function to fail. The addition of driving devices will further increase the weight of the ship and reduce the ship's effective cargo capacity.

[0004] In the prior art, for example, the patent with publication number CN106347597B discloses a platform system for near-coastal scientific research ships; it is proposed in the article to fix the counterweight inside the inner circle of the platform base to lower the center of gravity of the platform system, so that the platform system is in a horizontal position, and the weight of the counterweight is 3 to 8 times greater than the load borne on the platform; the weight of the counterweight block in the above-mentioned existing device is directly linked to the actual size of the device. If the counterweight block is heavier, it will affect the distribution of the center of gravity of the ship and change the stability of the ship. Therefore, the indirect increase of the stability of the platform by the counterweight block has low applicability.

[0005] It is also proposed in the article that the locking device is inserted into the locking device hole on the platform and the locking device hole on the flat base, so that the platform system becomes a rigid system, which is convenient for transportation and storage; however, when converted into a rigid system, the device loses its anti-sway function, and if the locking device is accidentally loosened or fails during the navigation of the ship, it may cause the shaking of the platform system to intensify, and even damage the equipment on the platform. If the locking device is turned on in the initial situation, if the ship is sailing and there are violent ups and downs, the platform will also shake violently with the hull, causing damage to the instruments installed on the platform. The above-mentioned device requires manual release of the limit on the platform, but people cannot reach the operation site in bad weather, so its applicability is limited.

[0006] Therefore, under the above-stated viewpoint, there is still room for improvement in the existing ship stabilizing platforms. Summary of the invention

[0014] Preferably, a bent frame plate is provided on the front side of the lower rectangular frame, a strip plate is provided inside the bent frame plate, and two floating plates are hingedly provided on one side of the strip plate.

[0015] A transverse groove and a longitudinal groove are provided on one side of the strip plate outside the lower rectangular frame. A transverse axis and a longitudinal axis are rotatably arranged in the transverse groove and the inner groove, and the two floating plates are respectively connected to the transverse axis and the longitudinal axis.

[0016] Preferably, the transmission assembly includes structural grooves which are symmetrically opened inside the strip plate and respectively intersected with the transverse groove and the longitudinal groove; a limit plate is provided on the inner wall of the structural groove; a transmission shaft is rotatably provided on the limit plate; an annular groove is opened on the outer side of the transverse shaft; an inner gear ring is provided on the inner wall of the annular groove; the transmission shaft in the corresponding structural groove is connected to the inner gear ring through a gear transmission method, and the transmission shaft on the other side is connected to the corresponding longitudinal shaft.

[0019] In summary, the present application includes at least one of the following beneficial technical effects:

[0020] 1. The present invention uses a transmission component, a drive unit and a support unit, and uses the principle that the float can swing with the ups and downs of the water surface to convert the swinging force of the float through the transmission component and the drive unit into the power for the reverse swing of the stable platform; effectively offset the shaking of the ship, ensure that the stable platform is always flush with the water surface when the ship is sailing, and greatly improve the stability of the ship's navigation.

[0021] 2. The present invention provides an adjustable float position pushing component. Before the ship sails, the pushing cylinder in the pushing component is started to drive the strip plate to move up and down, so that the float plate is in good contact with the water surface, ensuring the normal operation of the anti-sway function; when the ship is in a scene where the anti-sway function is not needed, the pushing cylinder is operated in reverse to drive the strip plate to be retracted into the bent frame plate, so that the float plate is located below the water surface, adapting to different navigation needs and flexibly responding to various sea conditions.

[0022] 3. The present invention sets a support frame with telescopic plates on both sides of the bending frame plate. When the strip plate is retracted into the bending frame plate, the floating plate will move accordingly; at this time, the bottom of the floating plate contacts the telescopic end of the telescopic plate on the support frame. The telescopic plate starts and extends, and performs position limiting resistance against the bottom of the floating plate; under this resistance, the inner side of the floating plate is tightly attached to the outer side of the upper rectangular frame, and the upper stable platform of the floating plate is perpendicular to the outer side of the upper rectangular frame, thereby indirectly making the stable platform flush with the upper stable platform of the upper rectangular frame; this design optimizes the stability and coordination of the overall structure of the ship and reduces the shaking amplitude of the ship during navigation.

DETAILED DESCRIPTION

[0041] The following combination Figures 1 to 16 Embodiments of the present invention are described in detail.

[0042] The application embodiment discloses an anti-sway platform for ships, which explains that the application is mainly used in the process of ship navigation, and can offset the swinging force of the ship on the water surface in terms of technical effect, so that the stable platform is always flush with the water surface; especially in complex sea conditions with strong winds and waves, it can effectively ensure the smooth navigation of the ship; further, the application can also adjust the position of the float according to actual needs to avoid the float being submerged in the water, and when the anti-sway function is not needed, the float can be retracted below the water surface.

[0043] Example 1: Reference Figure 1 , Figure 2 and Figure 3 As shown, it includes an upper rectangular frame 1, a lower rectangular frame 10, a stabilizing platform 11, a support block 12, a main shaft 13, a support unit 2, a driving unit 3, a bent frame plate 14, a strip plate 15, a floating plate 16 and a transmission assembly 5. The lower rectangular frame 10 is located at the lower end of the upper rectangular frame 1. A rectangular groove is opened on the upper rectangular frame 1. The stabilizing platform 11 is located in the rectangular groove. Four support blocks 12 with equal spacing and a U-shaped cross-section are arranged on the inner bottom wall of the upper rectangular frame 1. Main shafts 13 are symmetrically arranged on both sides of the support blocks 12 for rotation. A support unit 2 for supporting the main shaft 13 and the stabilizing platform 11 is arranged between the main shaft 13 and the stabilizing platform 11. The stabilizing platform 11 is the anti-sway platform in this application.

[0044] A driving unit 3 for driving the four main shafts 13 to rotate respectively is arranged between the upper rectangular frame 1 and the lower rectangular frame 10 .

[0045] A bending frame plate 14 is arranged at the front side of the lower rectangular frame 10, a strip plate 15 is arranged inside the bending frame plate 14, and two floating plates 16 are hingedly arranged on one side of the strip plate 15 outside the bending frame plate 14, and the floating plates 16 swing along with the water surface.

[0046] A transmission assembly 5 for connecting the floating plate 16 with the driving unit 3 is arranged in the bent frame plate 14. The floating plate 16 swings along with the water surface, and the swinging force is transmitted to the driving unit 3 through the transmission assembly 5. The driving unit 3 drives the rotating shaft to rotate, and the rotating shaft drives the stabilizing platform 11 to swing through the supporting unit 2, so that when the ship sways on the water surface, the stabilizing platform 11 can always be flush with the water surface to offset the swinging force of the ship.

[0047] In the initial situation, the lower rectangular frame 10 in the present invention is placed on the ground, and then a water surface simulation device is built on the ground to drive the floating plate 16 to swing, thereby achieving a stabilizing effect on the stable platform, and a stabilization experiment is carried out on the ground. Furthermore, the upper rectangular frame 1 and the lower rectangular frame can also be installed in the hull during the construction of the ship, and after being installed on the hull, the floating plate 16 in the above implementation process is located outside the hull, so that the floating plate 16 can contact the water surface during the navigation of the ship, so that the floating plate 16 can indirectly drive the stable platform 11 to swing according to the swing of the water surface, thereby achieving a stabilizing effect.

[0048] In combination with the above implementation process, the device can be used to conduct ground stability experiments in combination with a water surface simulation device built on the ground, and can also be installed in the hull to play a stabilizing role during the navigation of the ship. In the subsequent implementation process, if no explanation is given, the description of the implementation process defaults to being installed on the hull and moving with the hull in the water.

[0049] Continue to refer to Figure 3 , Figure 4 and Figure 5 As shown, a support unit 2 is used to support it; specifically, the support unit 2 includes a support plate 20, a main cylinder 21, a screw sleeve 22, a ball 23 and a rotating shaft 24, the support plate 20 is arranged on the outer sides of the corresponding two main shafts 13, and the main cylinder 21 is arranged on the support plate 20, that is, the support plate 20 is used to support the main cylinder 21, and the main cylinder 21 can also swing on the corresponding support block 12 through the main shaft 13 when driven by external force.

[0050] A screw sleeve 22 is connected to the inner thread of the main cylinder 21, and a ball 23 is provided at one end of the screw sleeve 22 located outside the main cylinder 21, and the ball 23 is rotatably connected to the side corresponding to the stabilizing platform 11. When the screw sleeve 22 is driven to rotate by an external force, it can move up and down in the main cylinder 21, and during the movement, it can drive the stabilizing platform 11 to swing through the corresponding ball 23. The front and rear and left and right corresponding screw sleeves 22 are respectively a group, which are used to drive the stabilizing platform 11 to swing left and right and front and back, respectively. The left and right screw sleeves 22 move in opposite directions up and down together to drive the stabilizing platform 11 to swing left and right. The front and rear screw sleeves 22 move in opposite directions up and down together, which will drive the stabilizing platform 11 to swing forward and backward to offset the front and rear and left and right swings of the ship.

[0051] During this process, since the stabilizing platform 11 and the ball 23 are rotatably connected, this can prevent the stabilizing platform 11 from interfering with the swinging direction of the screw sleeves 22 on the other two sides when it swings in one direction. In addition, during the movement of the stabilizing platform 11, the main cylinder 21 will also adaptively swing in the support block 12 through the main shaft 13 to prevent the swing amplitude of the stabilizing platform 11 from being limited.

[0052] A rotating shaft 24 is also slidably provided inside the main cylinder 21, one side of which extends into the interior of the screw sleeve 22, and the rotating shaft 24 is connected to the inner side wall of the screw sleeve 22 by a keyway sliding manner, that is, when the rotating shaft 24 is driven by an external force, it can drive the screw sleeve 22 to rotate in the main cylinder 21 by means of the keyway cooperation, and move in the up and down directions simultaneously. Because the rotating shaft 24 and the screw sleeve 22 are connected by means of the keyway cooperation, the screw sleeve 22 can be driven to rotate by the rotating shaft 24, and can also move in the up and down directions under the limit of the main cylinder 21 without interfering with the rotating shaft 24.

[0053] Continue to refer to Figure 5 , Figure 6 , Figure 7 , Figure 8 and Fig. 9 As shown, the driving unit 3 is used to drive the four main shafts 13 to rotate respectively; specifically, the driving unit 3 includes a cross plate 30, a driving rod 31, a driving gear 32, a driving rack 33, an extension plate 34, a threaded bar 35, a driving cylinder 36, a driving shaft 37 and a threaded disk 38. The cross plate 30 is arranged inside the support block 12, and a driving rod 31 is rotatably arranged on the cross plate 30. The cross plate 30 is used to limit the driving rod 31 so that the driving rod 31 can rotate.

[0054] One end of the rotating shaft 24 passes through the support plate 20 and is connected to the upper end of the driving rod 31 in a hinged manner. When the driving rod 31 rotates, it can synchronously drive the rotating shaft 24 to rotate, thereby driving the screw sleeve 22 to rotate. When the rotating shaft 24 swings with the main cylinder 21, since the rotating shaft 24 and the driving rod 31 are hinged, the driving rod 31 can continue to drive the rotating shaft 24 to rotate.

[0055] A driving gear 32 is sleeved on the outside of the driving rod 31, and a driving rack 33 is slidably arranged inside the support block 12. The driving rack 33 can move toward the inside or outside of the rectangular groove under the limitation of the support block 12, and during the movement, the corresponding driving rod 31 can be driven to rotate by the driving gear 32.

[0056] An extension plate 34 is provided on one side of the driving rack 33 facing the upper rectangular frame 1 , and threads 35 are provided on the lower sides of the corresponding extension plates 34 on both sides. The extension plates 34 can drive the corresponding driving rack 33 to move synchronously when driven by external force.

[0057] The other two extension plates 34 have threads 35 on their upper sides, and the threads 35 on the front and rear and left and right extension plates 34 are not aligned in vertical direction, only the threads 35 on the extension plates 34 on both sides are aligned in direction.

[0058] A circular groove is formed on the inner bottom wall of the upper rectangular frame 1 and the inner top wall of the lower rectangular frame 10. A driving cylinder 36 is rotatably arranged in the circular groove, and a driving shaft 37 is rotatably arranged on the bottom of the lower rectangular frame 10, with one side passing through the interior of the driving cylinder 36 and located in the upper rectangular frame 1. The driving cylinder 36 can rotate under the limit of the circular groove, and the driving shaft 37 can rotate under the limit of the inner bottom wall of the lower rectangular frame 10.

[0059] The driving cylinder 36 and the driving shaft 37 are located on the outer side of the upper rectangular frame 1 and are sleeved with symmetrically distributed threaded disks 38, and the two threaded disks 38 are respectively located on the upper and lower sides of the driving rack 33 and are threadedly connected to the corresponding threaded strips 35. The driving cylinder 36 and the driving shaft 37 can drive the corresponding threaded disks 38 on the outer side to rotate. Since the directions of the threaded strips 35 on the corresponding extension plates 34 on both sides are consistent, and the corresponding extension plates 34 on both sides and the threaded strips 35 with the same directions are a group, the two threaded disks 38 respectively drive the extension plates 34 to move through the corresponding two threaded strips 35, so that the extension plates 34 can drive the corresponding two driving racks 33 to move in relative or opposite directions, and the two driving racks 33 will drive the two screw sleeves 22 to move in opposite directions through the corresponding driving gears 32, thereby driving the stable platform 11 to swing.

[0060] Reference Fig.10As shown, a transverse groove 4 and a longitudinal groove 40 are provided on one side of the strip plate 15 outside the lower rectangular frame 10, and a transverse axis 41 and a longitudinal axis 42 are rotatably arranged in the transverse groove 4 and the longitudinal groove 40, and the two floating plates 16 are respectively connected to the transverse axis 41 and the longitudinal axis 42, that is, the transverse axis 41 and the longitudinal axis 42 can rotate in the corresponding transverse groove 4 and the longitudinal groove 40, so that the two floating plates 16 can swing at the end of the strip plate 15 through the corresponding transverse axis 41 and the longitudinal axis 42, and because the directions of the transverse axis 41 and the longitudinal axis 42 are inconsistent, the swinging directions of the two floating plates 16 are not consistent. When the ship swings up and down, the floating plate 16 corresponding to the transverse axis 41 will swing in the up and down direction, and when the ship swings left and right, the floating plate 16 corresponding to the longitudinal axis 42 will swing left and right.

[0061] Continue to refer to Fig.10 , Fig.11 , Fig.12 , Fig.13 and Fig.14 As shown, the transmission assembly 5 is used to connect the floating plate 16 with the driving unit 3; specifically, the transmission assembly 5 includes a structural groove 50, a limiting plate 51, a transmission shaft 52, an inner gear ring 53, an extension shaft 54, an outer gear ring 55 and a gear transmission mechanism 56. The two structural grooves 50 are symmetrically arranged inside the strip plate 15 and are respectively connected with the transverse groove 4 and the longitudinal groove 40. The inner wall of the structural groove 50 is provided with a limiting plate 51, and a transmission shaft 52 is rotatably provided on the limiting plate 51. The transmission shaft 52 can rotate in the structural groove 50 under the limitation of the limiting plate 51.

[0062] An annular groove is provided on the outer side of the horizontal shaft 41, and an inner gear ring 53 is provided on the inner wall of the annular groove. The transmission shaft 52 in the corresponding structural groove 50 is connected to the inner gear ring 53 through gear transmission, and the transmission shaft 52 on the other side is connected to the corresponding longitudinal shaft 42. That is, when the horizontal shaft 41 rotates, it can drive the corresponding transmission shaft 52 to rotate through the inner gear ring 53 and gear transmission, and when the longitudinal shaft 42 rotates, it will directly drive the corresponding transmission shaft 52 to rotate.

[0063] An extension shaft 54 ​​is symmetrically provided on one side of the bent frame plate 14 located at the lower rectangular frame 10 , and the extension shaft 54 ​​is connected to the corresponding transmission shaft 52 by a hinged manner, and the transmission shaft 52 can drive the corresponding extension shaft 54 ​​to rotate.

[0064] The driving cylinder 36 and the driving shaft 37 are located on the outer side of the lower rectangular frame 10 and are sleeved with an outer gear ring 55, and the heights of the two outer gear rings 55 are inconsistent, and the sizes of the two outer gear rings 55 are also inconsistent. The two extension shafts 54 are respectively meshed with the corresponding outer gear rings 55 through gear transmission, that is, the two outer gear rings 55 can respectively drive the corresponding driving cylinder 36 and driving shaft 37 to rotate, and two sets of gear transmission mechanisms 56 are arranged at the bottom of the lower rectangular frame 10, one side of the gear transmission mechanism 56 is connected to the corresponding extension shaft 54, and the other side of the gear transmission mechanism 56 is respectively connected to the corresponding outer gear ring 55, that is, due to the inconsistent sizes and heights of the two outer gear rings 55, a single gear transmission mechanism 56 will only mesh with the corresponding outer gear ring 55, and the gear transmission mechanism 56 is a transmission mechanism composed of multiple rotating rods and bevel gears, and its purpose is to transmit the rotational force of the extension shaft 54 ​​to the corresponding outer gear ring 55.

[0065] Therefore, when the ship sways back and forth, the float 16 on one side contacts the water surface and is indirectly lifted up by the ship or dropped onto the water surface. During this process, the float 16 can drive the corresponding transverse axis 41 to rotate, and the transverse axis 41 indirectly drives the drive shaft 37 to rotate through the outer gear ring 55. The drive shaft 37 will drive the front and rear corresponding screw sleeves 22 to move through the threaded disk 38, and the front and rear corresponding screw sleeves 22 will drive the stabilizing platform 11 to swing in the front and rear directions, and the swinging direction of the stabilizing platform 11 is opposite to the swinging direction of the ship, thereby offsetting the shaking of the ship.

[0066] Similarly, when the ship sways from side to side, the float 16 on the other side contacts the water surface and is indirectly lifted up by the ship or dropped onto the water surface. During this process, the float 16 can drive the corresponding longitudinal axis 42 to rotate. The longitudinal axis 42 indirectly drives the driving cylinder 36 to rotate through the outer gear ring 55. The driving cylinder 36 will drive the corresponding left and right screw sleeves 22 to move through the threaded disk 38. The corresponding left and right screw sleeves 22 will drive the stabilizing platform 11 to swing left and right, and the swinging direction of the stabilizing platform 11 is opposite to the swinging direction of the ship, thereby offsetting the shaking of the ship and finally realizing the anti-sway function of the stabilizing platform 11.

[0067] Example 2: Reference Fig.15As shown, on the basis of the first embodiment, in order to make the floating plate 16 perpendicular to the water surface and prevent the floating plate 16 from being submerged in the sea water, the strip plate 15 is slidably connected to the inside of the bending frame plate 14, and a through groove 60 is opened on the upper side of the bending plate, and a protective shell 61 that is connected to the through groove 60 is also provided on the bending plate, and a pushing component 6 for pushing the strip plate 15 to move is provided in the protective shell 61; specifically, the pushing component 6 includes a through groove 60, a protective shell 61, a pushing cylinder 62, a pushing plate 63 and a sliding rod 64, the pushing cylinder 62 is installed in the protective shell 61 through a cylinder seat, and a pushing plate 63 is provided at the telescopic end of the pushing cylinder 62, and one side of the pushing plate 63 passes through the through groove 60 and is connected to the strip plate 15.

[0068] It should be noted that after the device is installed on the hull, the end of the bent frame plate 14 is located on the outside of the hull, so that the float 16 can contact the water surface. When the device is not installed in the hull, that is, placed on land, the float 16 can be pushed to swing through a water surface simulation platform built on the ground, so that the stable platform 11 can carry out a stability experiment of sailing shaking on the ground.

[0069] It should be noted that the (water surface simulation platform) proposed in the above implementation process is a well-known technology, which is similar to a pool that can simulate water flow impulses. The device is placed inside, and the float 16 is driven to swing by water flow, thereby driving the stable platform to move. Technical personnel in this field can drive the float 16 to swing in different ways according to actual usage requirements.

[0070] That is, before the ship sails, the push plate 63 is driven to move in the through groove 60 by pushing the cylinder 62, so that the push plate 63 can drive the corresponding strip plate 15 to move in the up and down directions, thereby driving the floating plate 16 to contact the water surface, preventing the floating plate 16 from being lower than or higher than the sea water, and the floating plate 16 can swing normally under the push of the water surface.

[0071] Since the push cylinder 62 is installed in the protective shell 61, it can effectively avoid seawater erosion and extend the service life; in multiple navigation tests, after experiencing winds and waves of different degrees, the device can respond in time and accurately adjust the position of the float 16 to ensure the smooth navigation of the ship, which greatly improves the ship's ability to cope with complex sea conditions.

[0072] A sliding rod 64 is slidably provided on one side of the corresponding transmission shaft 52 toward the extension shaft 54 ​​by means of a keyway fit, and the sliding rod 64 is hinged to the corresponding extension shaft 54. Therefore, when the strip plate 15 slides in the bending frame plate 14, the transmission shaft 52 and the sliding rod 64 can be adaptively extended and retracted, and by means of a keyway sliding fit, the transmission shaft 52 can drive the extension shaft 54 ​​to rotate through the sliding shaft.

[0073] Furthermore, when the float 16 is not needed to swing with the water surface, that is, the anti-sway function of the stable platform 11 is not needed at this time, the strip plate 15 is indirectly driven to be retracted into the bent frame plate 14 by pushing the cylinder 62, so that the float 16 is located below the water surface.

[0074] Example 3: Reference Fig.16 As shown, on the basis of the second embodiment, support frames 7 are provided on both sides of the bent frame plate 14, and a telescopic plate 70 is installed on the side of the support frame 7 facing the floating plate 16, and the telescopic end of the telescopic plate 70 is in contact with the bottom of the corresponding floating plate 16, and the inner side wall of the floating plate 16 corresponds to the outer side of the upper rectangular frame 1 and is in contact with it.

[0075] That is, when the upper end of the floating plate 16 is perpendicular to the vertical surface of the upper rectangular frame 1, the stabilizing platform 11 remains straight with the upper side of the upper rectangular frame 1. When the strip plate 15 is extended into the bent frame plate 14, the inner side of the floating plate 16 can contact the outer side of the upper rectangular frame 1 and is limited to a certain degree of angle. However, since the stabilizing platform is in contact with the outer side of the upper rectangular frame 1, the floating plate 16 will still be tilted to a certain extent, resulting in a certain deviation between the stabilizing platform 11 and the stabilizing platform of the upper rectangular frame 1.

[0076] Therefore, when the strip plate 15 moves to the inside of the bent frame plate 14, the floating plate 16 will also move into the sea water, and its bottom will contact the telescopic end of the telescopic plate 70, and the telescopic plate 70 will limit the bottom of the floating plate 16, so that the inner side of the floating plate 16 is tightly attached to the outer side of the upper rectangular frame 1, and the upper stable platform of the floating plate 16 is driven to be perpendicular to the outer side of the upper rectangular frame 1, indirectly making the stable platform 11 flush with the upper stable platform of the upper rectangular frame 1.

[0077] During operation: Step 1: During the navigation of the ship, the water surface fluctuates, and the floating plate 16 hinged on the strip plate 15 inside the bent frame plate 14 at the front side of the lower rectangular frame 10 begins to swing along with the water surface.

[0078] Step 2: When the floating plate 16 swings, it drives the horizontal axis 41 or the vertical axis 42 connected thereto to rotate, and through the gear transmission method, the transmission shaft 52 in the internal structural groove 50 of the strip plate 15 rotates.

[0079] Step 3: The rotating transmission shaft 52 drives the extension shaft 54 ​​hinged thereto to rotate, and the extension shaft 54 ​​drives the outer gear ring 55 outside the drive cylinder 36 and the drive shaft 37 to rotate through the gear transmission mechanism 56, thereby driving the drive cylinder 36 and the drive shaft 37 to rotate.

[0080] Step 4: When the driving cylinder 36 and the driving shaft 37 rotate, the threaded disc 38 sleeved on the outer side of the upper rectangular frame 1 is driven to rotate. The threaded disc 38 is connected with the threaded strip 35 on the extension plate 34 through the thread, thereby driving the extension plate 34 to move.

[0081] Step 5: The extension plate 34 moves to drive the driving rack 33 connected thereto to move in the support block 12 , and the driving rack 33 drives the driving rod 31 to rotate by cooperating with the driving gear 32 .

[0082] Step 6: The driving rod 31 rotates, and the screw sleeve 22 is driven to rotate through the hinged rotating shaft 24. The screw sleeve 22 moves up and down in the main tube 21, and the rolling ball 23 is used to drive the stabilizing platform 11 to swing, so that the swing direction of the stabilizing platform 11 is opposite to the swing direction of the ship, thereby offsetting the shaking of the ship.

[0083] In the scenario of the second embodiment, before the ship sails, the push cylinder 62 will first drive the push plate 63 to move in the through slot 60, driving the strip plate 15 to move up and down, so that the floating plate 16 contacts the water surface. When the anti-sway function is not needed, the push cylinder 62 indirectly drives the strip plate 15 to be retracted into the bent frame plate 14, so that the floating plate 16 is located below the water surface.

[0084] In the scenario of Example 3, when the strip plate 15 is retracted into the bent frame plate 14, the bottom of the floating plate 16 contacts the telescopic end of the telescopic plate 70 on the support frame 7, and the telescopic plate 70 limits the bottom of the floating plate 16, so that the inner side of the floating plate 16 is tightly attached to the outer side of the upper rectangular frame 1, and the upper stable platform is perpendicular to the outer side of the upper rectangular frame 1, indirectly making the stable platform 11 flush with the upper stable platform of the upper rectangular frame 1.

Therefore, the embodiments should be considered as exemplary and non-restrictive in all respects.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole.
