Description

Technical Field

[0001] The invention relates to the technical field of ship launching, in particular to a propulsion device for a yacht launching system. Background Art

[0002] A yacht is a kind of ship that integrates various functions such as navigation, sports and entertainment. There are various types of yachts, including large yachts such as cruising yachts and super yachts, and also small yachts such as speedboats, inflatable boats and motorboats. When a small yacht comes ashore or is launched, the yacht is generally pulled ashore or slid into the water along a track with a certain slope.

[0003] Currently, when a small yacht is launched, it generally slides into the water from a slide under the action of gravity. However, the launching speed of the small yacht is difficult to control. When the sea waves are large, the sea waves will generate a large impact force on the small yacht, and the small yacht is very likely to be unstable when sliding into the water, resulting in the small yacht swaying and tilting, which affects safety. Therefore, it is urgent to develop a propulsion device for a yacht launching system to reduce the impact on the small yacht during launching and improve safety. Summary of the Invention

Detailed implementation manners

[0029] The present invention will be specifically introduced below in conjunction with the accompanying drawings and specific embodiments. Embodiment

[0030] A propulsion device for a yacht launching system, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 11 and Figure 12 shown, includes a mounting frame 1, a first rotating plate 2, a rotating shaft 21, a second rotating plate 3, a horizontal lifting frame 4, a bump 41, a connecting frame 5, a ramp frame 6, a mounting rod 7, a water deflecting mechanism, a buffer mechanism, a driving assembly and a supporting mechanism.

The bumps 41 are all movable in the adjacent guide holes 40. The middle part of the horizontal lifting frame 4 is welded with a connecting frame 5. The front side of the connecting frame 5 is fixedly connected with a ramp frame 6. The top of the horizontal lifting frame 4 is welded with a mounting rod 7.

The driving assembly includes a first waterproof motor 101 and a gear set 102. The first waterproof motor 101 is bolted to the rear part of the mounting frame 1. The output shaft of the first waterproof motor 101 is transmitted to the rotating shaft 21 through the gear set 102. By controlling the first waterproof motor 101, the rotating shaft 21 can be driven to rotate, so that the first rotating plate 2 and the second rotating plate 3 rotate.

[0031] As Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 11 and Figure 12As shown in the figure, the water deflecting mechanism includes a baffle 80, a support plate 81, a water deflecting plate 82, a connecting plate 83, a fixing rod 84, a sliding rod 85, a first compression spring 86, a guide block 87 and a sliding block 88. Baffles 80 are symmetrically welded to the left and right of the bottom of the connecting frame 5. Support plates 81 are symmetrically welded to the front side of the mounting frame 1. Water deflecting plates 82 are rotatably connected to the lower parts of the support plates 81. The water deflecting plates 82 are respectively abutted against the adjacent baffles 80. Two symmetrically arranged connecting plates 83 are fixedly connected to the mutually remote sides of the water deflecting plates 82. The mutually remote sides of the same-side connecting plates 83 are both inclined surfaces. Guide blocks 87 are fixedly connected to the mutually remote sides of the water deflecting plates 82. Sliding blocks 88 are slidably connected to the guide blocks 87. Fixing rods 84 are symmetrically fixedly connected to the front side of the mounting frame 1. Sliding rods 85 are slidably connected to the fixing rods 84. First compression springs 86 are connected between the sliding rods 85 and the adjacent fixing rods 84. The sliding rods 85 are respectively rotatably connected to the adjacent sliding blocks 88.

[0032] As Figure 2 and Figure 6 shown in the figure, the buffer mechanism includes a guide rod 91, a buffer rod 92, a second compression spring 93 and a roller 94. Four groups of guide rods 91 are fixedly connected to the connecting frame 5. The number of each group of guide rods 91 is two. Buffer rods 92 are slidably connected between the two guide rods 91 in the same group. Dampers are provided at the sliding connections between the buffer rods 92 and the adjacent guide rods 91. Second compression springs 93 are connected between the buffer rods 92 and the connecting frame 5. Rollers 94 are rotatably connected to the buffer rods 92.

[0033] As Figure 1 、 Figure 7 、 Figure 8 、 Figure 11 and Figure 12As shown in the figure, the support mechanism includes a connecting block 110, an arc-shaped rack 111, a first screw rod 112, a full gear 113, a connecting rod 114, a support frame 115, a roller 116, a bending part 117 and an elastic rubber block 118. Connecting blocks 110 are symmetrically and fixedly connected to the left and right sides of the rear side of the mounting frame 1. Full gears 113 are rotatably connected to the connecting blocks 110. A connecting rod 114 is fixedly connected to the rear side of the mounting frame 1. Support frames 115 are symmetrically and slidably connected to the left and right sides of the connecting rod 114. A plurality of rollers 116 are rotatably connected to the lower parts of the support frames 115. First screw rods 112 are fixedly connected to the rear parts of the support frames 115. The first screw rods 112 are threadedly connected to the adjacent full gears 113. One end of the first rotating plate 2 close to the rotating shaft 21 is fixedly connected with an arc-shaped rack 111. The arc-shaped racks 111 are meshed with the adjacent full gears 113. When the first rotating plate 2 rotates, it drives the arc-shaped rack 111 to rotate, enabling the full gears 113 to rotate synchronously, so that the first screw rods 112 and the support frames 115 move horizontally towards the side close to the horizontal lifting frame 4. Two bending parts 117 are provided at the tops of the support frames 115. Elastic rubber blocks 118 are fixedly connected to the support frames 115 at the bending parts 117. When the support frames 115 and the elastic rubber blocks 118 are directly below the horizontal lifting frame 4, they can support the horizontal lifting frame 4, thus playing a supporting role.

[0034] Initially, the first compression spring 86 is in a compressed state, and the water surface is higher than the roller 94. When the yacht needs to come ashore, equipment for towing the yacht can be installed through the mounting rod 7. The yacht enters from the ramp frame 6 and drives to directly above the roller 94. When the yacht presses the roller 94, the second compression spring 93 deforms adaptively, which can play a buffering role. Under the driving of the gear set 102, the first waterproof motor 101 is controlled to drive the rotating shaft 21 to rotate counterclockwise, driving the first rotating plate 2 to rotate counterclockwise, thereby driving the horizontal lifting frame 4, the baffle 80 and the convex block 41 to move upward, so that the convex block 41 moves in the guiding hole 40 towards the direction close to the mounting frame 1, enabling the horizontal lifting frame 4 to always maintain a horizontal state, so that the roller 94 and the yacht maintain a horizontal state. When the horizontal lifting frame 4 and the yacht are lifted, refer to Figure 11, meanwhile, the first rotating plate 2 drives the arc-shaped rack 111 to rotate counterclockwise. Under the meshing action, the full gear 113 rotates clockwise. Under the action of the threaded connection, the two first screw rods 112 move towards the side close to each other, driving the support frame 115 and the elastic rubber block 118 to move horizontally towards the side close to the horizontal lifting frame 4. When the horizontal lifting frame 4 contacts the elastic rubber block 118, the horizontal lifting frame 4 squeezes the elastic rubber block 118 to deform, and the thickness of the elastic rubber block 118 decreases. When the horizontal lifting frame 4 continues to move upward to an appropriate height, the support frame 115 and the elastic rubber block 118 move an appropriate distance towards the side close to the horizontal lifting frame 4 at the same time, and the extrusion force on the elastic rubber block 118 decreases, and the elastic rubber block 118 returns to its original state. At this time, the top of the elastic rubber block 118 is completely in contact with the bottom of the horizontal lifting frame 4, and the support frame 115 can support the horizontal lifting frame 4 to prevent the horizontal lifting frame 4 and the yacht from falling downward under the action of gravity. When the baffle 80 moves upward and separates from the water deflecting plate 82, the first compression spring 86 returns to its original state, driving the sliding block 88 to move towards the side close to each other, thereby driving the sliding rod 85 and the guide block 87 to move horizontally towards the side close to the yacht, and can push the two water deflecting plates 82 to rotate towards the side close to each other, so that the two water deflecting plates 82 are closed. The closed state refers to Figure 12 , in this way, the yacht can be lifted to a height above the water surface to prevent the yacht from being damaged and corroded by long-term immersion. When the yacht needs to be launched into the water, control the first waterproof motor 101 to drive the first rotating plate 2 and the second rotating plate 3 to rotate clockwise. Similarly, the horizontal lifting frame 4, the baffle 80, the convex block 41 and the yacht can be moved downward. The horizontal lifting frame 4, the roller 94 and the yacht remain in a horizontal state. Under the cooperation of the arc-shaped rack 111 and the full gear 113, the two first screw rods 112 can move towards the side far from each other to reset, so that the support frame 115 and the elastic rubber block 118 move horizontally towards the side far from the horizontal lifting frame 4 to reset. The horizontal lifting frame 4 squeezes the elastic rubber block 118 to deform, and the thickness of the elastic rubber block 118 decreases. When the horizontal lifting frame 4 separates from the elastic rubber block 118, the elastic rubber block 118 returns to its original state. When the baffle 80 moves downward and contacts the water deflecting plate 82, the baffle 80 squeezes the two water deflecting plates 82 to rotate towards the side far from each other to reset. Similarly, the first compression spring 86 can be compressed. The two water deflecting plates 82 can block the sea waves to prevent the yacht from swaying and tilting under the impact of the sea waves, which is convenient for people to board the yacht. The water deflecting plates 82 can also block the water surface sundries to avoid the yacht colliding with the sundries. The connecting plate 83 can reduce the water return speed and reduce the impact force of the water flow on the yacht, so as to smoothly push the yacht into the water and improve the safety. Embodiment

[0035] On the basis of Embodiment 1, as Figure 1 , Figure 2 andFigure 9 As shown, it further includes a clamping mechanism. The clamping mechanism includes a mounting plate 121, a second waterproof motor 122, a second screw rod 123, a transmission wheel 124, a synchronous belt 125, a sliding frame 126, a clamping frame 127, a third compression spring 128 and a sponge pad 129. On the front side of the top of the horizontal lifting frame 4, mounting plates 121 are symmetrically and fixedly connected on the left and right. Second waterproof motors 122 are bolted to the tops of the mounting plates 121. Second screw rods 123 are rotatably connected to the mounting plates 121 in a front-back symmetrical manner. Transmission wheels 124 are fixedly connected to the output shafts of the second screw rods 123 and the second waterproof motors 122. Synchronous belts 125 are wound between the three transmission wheels 124 on the same side. The three transmission wheels 124 on the same side are all driven by the adjacent synchronous belts 125. When the second waterproof motor 122 controls the rotation of the two upper transmission wheels 124, the other four transmission wheels 124 can rotate synchronously under the action of the synchronous belt 125. Sliding frames 126 are slidably connected to the mounting plates 121. The sliding frames 126 are threadedly connected to the two second screw rods 123 on the same side. Clamping frames 127 are slidably connected to the sides of the sliding frames 126 close to each other. A number of third compression springs 128 are connected between the clamping frames 127 and the adjacent sliding frames 126. Sponge pads 129 are connected to the sides of the clamping frames 127 close to each other. When the two clamping frames 127 are both in contact with the yacht, the sliding frames 126 move towards the side close to the yacht. Under the action of the third compression springs 128, the clamping frames 127 can clamp the yacht, so that the yacht is stable when launched into the water and the shaking of the yacht is reduced.

[0036] When the yacht is directly above the roller 94 and the yacht leaves the water surface, control the second waterproof motor 122 to drive the two driving wheels 124 on the upper side to rotate. Under the driving action of the synchronous belt 125, drive the four driving wheels 124 on the lower side to rotate, so that the four second screw rods 123 rotate synchronously. Under the action of the threaded connection, the two sliding brackets 126 can move towards the side close to each other, drive the clamping brackets 127 to move towards the side close to each other, and then drive the sponge pads 129 to move towards the side close to each other. When one of the sponge pads 129 contacts the yacht, the sponge pad 129 will push the yacht towards the middle, and the roller 94 will rotate under the action of friction. When both sponge pads 129 contact the yacht, the clamping brackets 127 and the sponge pads 129 stop moving, while the sliding brackets 126 continue to move towards the side close to each other, and the third compression spring 128 is compressed. In this way, the yacht can be clamped in the centered position, and the sponge pads 129 can reduce the surface wear of the yacht. When the yacht is pushed into the water, the clamping brackets 127 clamp the yacht, which can further make the yacht enter the water smoothly and improve safety. When the yacht enters the water smoothly, control the second waterproof motor 122 to drive the two driving wheels 124 on the upper side to reverse. Similarly, the sliding brackets 126 and the clamping brackets 127 can move away from the yacht. When the clamping brackets 127 are separated from the yacht, the third compression spring 128 returns to its original state, and the yacht can be released.

[0037] As Figure 1 and Figure 10 shown, it further includes a centering mechanism. The centering mechanism includes a fixed plate 131, a third rotating plate 132 and a fourth compression spring 133. The fixed plates 131 are symmetrically and fixedly connected to the left and right of the front part of the horizontal lifting frame 4. The third rotating plates 132 are symmetrically and rotatably connected to the left and right of the front part of the horizontal lifting frame 4. When the yacht comes ashore and touches the third rotating plate 132, the third rotating plate 132 can make the yacht move towards the centered position. The fourth compression springs 133 are connected between the third rotating plate 132 and the adjacent fixed plates 131. When the yacht enters from the ramp frame 6, if the position of the yacht is offset, when the yacht squeezes the third rotating plate 132 to rotate, the fourth compression spring 133 returns to its original state. Under the action of the fourth compression spring 133, the third rotating plate 132 can push the yacht towards the side close to the ramp frame 6, so that the position of the yacht is centered and the position offset of the yacht is prevented.

[0038] The above has introduced the present application in detail. Specific examples are used in this article to elaborate on the principle and implementation mode of the present application. The description of the above embodiments is only used to help understand the method and its core idea of the present application; at the same time, for those of ordinary skill in the art, according to the idea of the present application, there will be changes in the specific implementation mode and application scope. In summary, the content of this specification should not be construed as a limitation to the present application.
