[0001] The utility model belongs to the technical field of seaweed sowing and seedling planting equipment, and specifically relates to an aquatic mobile platform and a seaweed planting machine. Background Art

[0002] Seagrass plays a very important role in the marine ecological environment. It can not only improve water transparency, control shallow water quality, and resist waves and tides, but also is a natural barrier to protect shallow coasts. It also provides habitats and shelter for many animal species. Seagrass is usually planted in shallow coastal areas. The planting methods include direct sowing and seedling transplanting.

The planting time is very limited. Therefore, there is an urgent need to develop mechanical equipment that can perform efficient planting operations without being affected by the shallow coastal waters. Therefore, the first thing to do is to develop an operating platform that can operate stably and flexibly in the shallow coastal waters. Utility Model Content

In the description of the present application, the meaning of "multiple" and "several" is two or more, unless otherwise clearly and specifically defined.

[0025] Please also read Figures 1 to 5 , the mobile platform on water provided by the utility model is now described. The mobile platform on water includes a platform body 10 and a walking support assembly 20; the platform body 10 is provided with a buoy 11 and a water drive assembly 12; the walking support assembly 20 is arranged on the platform body 10, and has a plurality of supporting ends vertically extending to the bottom of the platform body 10, and the walking support assembly 20 has a supporting state in which each supporting end cooperates to support the underwater ground, and a suspended state in which each supporting end is separated from the underwater ground; wherein, in the suspended state, the platform body 10 floats on the water surface under the buoyancy of the buoy 11, and moves on the water surface driven by the water drive assembly 12; in the supporting state, the walking support assembly 20 can drive the platform body 10 to move longitudinally and transversely.

[0026] It should be noted that in this embodiment, the walking support assembly 20 drives the platform body 10 to move longitudinally and transversely, which can only meet the short-distance movement needs. The main purpose is to complete the adjustment of the front and rear plant spacing through longitudinal movement, and transfer to the next adjacent area through transverse movement after planting in one area is completed; when long-distance movement is required during high tide, the various support ends of the walking support assembly 20 can be suspended in the air, and then the buoyancy of the float 11 can be used to make the platform body 10 in a horizontal floating state, and then the water drive assembly 12 can be used to provide power to move the platform body 10 to the target planting area.

[0027] Compared with the prior art, the mobile water platform provided in this embodiment can utilize the buoy 11 to make the platform body 10 float on the water surface when the walking support assembly 20 is in a suspended state, and after the water drive assembly 12 provides power to move the platform body 10 to the target operation area for seaweed planting, the walking support assembly 20 is switched to a supporting state, so that the platform body 10 is stably supported in the target operation area for operation, and the target operation area is transferred through the longitudinal and lateral movements of the walking support assembly 20, and is not affected by the tides near the shallow sea coast, thereby solving the time limitation problem of being unable to plant operations during the tidal period and improving the flexibility of the operation time of seaweed planting.

[0028] In some embodiments, see Figures 1 to 3 The walking support assembly 20 includes a transverse support leg group and a longitudinal support leg group; the transverse support leg group is symmetrically arranged at the lateral ends of the platform body 10 along the longitudinal axis of the platform body 10; the longitudinal support leg group is symmetrically arranged at the longitudinal ends of the platform body 10 along the transverse axis of the platform body 10; wherein, in the supporting state, the transverse support leg group and the longitudinal support leg group are both supported on the underwater ground; when the transverse support leg group is separated from the underwater ground, the longitudinal support leg group supports the underwater ground and drives the platform body 10 to move longitudinally; when the longitudinal support leg group is separated from the underwater ground, the transverse support leg group supports the underwater ground and drives the platform body 10 to move laterally.

[0029] During normal planting operations, both the transverse leg group and the longitudinal leg group are supported on the underwater ground to ensure the stability of the platform body 10. When it is necessary to move longitudinally to the next working area, the longitudinal leg group is vertically extended or the transverse leg group is vertically shortened, thereby forming a suspended state of the transverse leg group, and then the longitudinal leg group drives the platform body 10 to move longitudinally through longitudinal extension and contraction; similarly, when it is necessary to move laterally to the next working area, the longitudinal leg group is vertically shortened or the transverse leg group is vertically extended, thereby forming a suspended state of the longitudinal leg group, and then the transverse leg group drives the platform body 10 to move laterally through transverse extension and contraction; of course, the transverse extension stroke of the transverse leg group and the longitudinal extension stroke of the longitudinal leg group determine the amplitude of a transverse or longitudinal movement of the platform body 10. If a single movement cannot reach the next working area, the above-mentioned actions can be repeated multiple times.

[0030] As a specific implementation of the above-mentioned traverse leg assembly, please refer to Figure 3 and Figure 4The transverse movement leg group includes two left legs 21 and two right legs 22, and the left legs 21 and the right legs 22 are symmetrically arranged along the longitudinal axis of the platform body 10; the left legs 21 and the right legs 22 both include a transverse movement telescopic member 211 laterally connected to the platform body 10, and a first telescopic support member 212 vertically connected to the telescopic end of the transverse movement telescopic member 211; wherein, when each first telescopic support member 212 is extended to separate the longitudinal movement leg group from the underwater ground, each transverse movement telescopic member 211 cooperates to drive the platform body 10 to move laterally, and when the longitudinal movement leg group supports the underwater ground and each first telescopic support member 212 is shortened to separate from the underwater ground, the longitudinal movement leg group drives the platform body 10 to move longitudinally.

[0031] The symmetrical distribution of the left leg 21 and the right leg 22 ensures that the force at each position of the platform body 10 is balanced, thereby improving the stability of the supporting state; when lateral movement, such as left movement, is required, each first telescopic support member 212 is synchronously extended, thereby driving the platform body 10 to rise so that the longitudinal leg group is suspended in the air, and then the transverse telescopic member 211 of the left leg 21 is shortened, and the transverse telescopic member 211 of the right leg 22 is extended, so that the platform body 10 is laterally moved to the left. If the transverse movement cannot be in place in one time, each first telescopic support member 212 is synchronously shortened until it is suspended in the air. At this time, the longitudinal leg group supports the underwater ground, and then the transverse telescopic member 211 of the left leg 21 is extended, and the transverse telescopic member 211 of the right leg 22 is shortened, and then each first telescopic support member 212 is synchronously extended until the longitudinal leg group is suspended again, and then the platform body 10 is driven to continue to move laterally to the left through the synchronous telescopic action of the transverse telescopic member 211 of the left leg 21 and the right leg 22, and this is repeated until it moves laterally to the target operating area.

[0032] Of course, when the platform body 10 needs to be moved longitudinally, the above process can be followed. When the first telescopic support member 212 is shortened to be suspended in the air, the platform body 10 can be driven to move longitudinally forward and backward by the longitudinally movable leg group.

[0033] For example, Figure 4 As shown, the above-mentioned transverse telescopic member 211 includes a first outer sleeve 2111 laterally fixed on the platform body 10, a first inner sleeve 2112 slidably connected to the first outer sleeve 2111, and a first hydraulic cylinder 2113 for driving the first inner sleeve 2112 to slide in the first outer sleeve 2111; wherein, one end of the first inner sleeve 2112 extends out of the first outer sleeve 2111 and is fixedly connected to the first telescopic support member 212; the telescopic actions of the first hydraulic cylinder 2113 of the left leg 21 and the right leg 22 are opposite.

[0034] Here, the first outer sleeve 2111 and the first inner sleeve 2112 are nested with each other to form a sliding fit and are extended and retracted under the drive of the first hydraulic cylinder 2113. When the longitudinal leg group is suspended, the first hydraulic cylinders 2113 of the left leg 21 and the right leg 22 move synchronously and in opposite directions to achieve the lateral movement of the platform body 10. The action is simple and stable. It should be noted that the above-mentioned first telescopic support member 212 can be a structure that is vertically arranged and driven by an inner and outer sleeve and a hydraulic cylinder like the lateral telescopic member, which will not be described in detail here.

[0035] As a specific implementation of the above-mentioned longitudinally movable leg group, please refer to Figure 2 and Figure 5 The longitudinal movement leg group includes two front legs 23 and two rear legs 24, and the front legs 23 and the rear legs 24 are symmetrically arranged along the transverse axis of the platform body 10; the front legs 23 and the rear legs 24 both include a longitudinal movement telescopic member 231 longitudinally connected to the platform body 10, and a second telescopic support member 232 vertically connected to the telescopic end of the longitudinal movement telescopic member 231; wherein, when each second telescopic support member 232 is extended to separate the transverse movement leg group from the underwater ground, each longitudinal movement telescopic member 231 cooperates to drive the platform body 10 to move longitudinally, and when the transverse movement leg group supports the underwater ground and each second telescopic support member 232 is shortened to separate from the underwater ground, the transverse movement leg group drives the platform body 10 to move laterally.

[0036] The symmetrical distribution of the front legs 23 and the rear legs 24 ensures that the force at each position of the platform body 10 is balanced, thereby improving the stability of the supporting state; when longitudinal movement, such as forward movement, is required, each second telescopic support member 232 is synchronously extended, thereby driving the platform body 10 to rise so that the transverse leg group is suspended in the air, and then the longitudinal telescopic member 231 of the front leg 23 is shortened, and the longitudinal telescopic member 231 of the rear leg 24 is extended, so that the platform body 10 is longitudinally moved forward. If the longitudinal movement cannot be in place in one time, each second telescopic support member 232 is synchronously shortened until it is suspended in the air. At this time, the transverse leg group supports the underwater ground, and then the longitudinal telescopic member 231 of the front leg 23 is extended, and the longitudinal telescopic member 231 of the rear leg 24 is shortened, and then each second telescopic support member 232 is synchronously extended until the transverse leg group is suspended again, and then the platform body 10 is driven to continue to move forward longitudinally through the synchronous telescopic action of the longitudinal telescopic member 231 of the front leg 23 and the rear leg 24, and this is repeated until the longitudinal movement reaches the target operating area.

[0037] Of course, when the platform body 10 needs to move laterally, the above process can be followed. When the second telescopic support member 232 is shortened to be suspended in the air, the platform body 10 can be driven to move laterally left and right by the transverse support leg group.

[0038] For example, Figure 5As shown, the longitudinal telescopic member 231 includes a second outer sleeve 2311 longitudinally fixed on the platform body 10, a second inner sleeve 2312 slidably connected to the second outer sleeve 2311, and a second hydraulic cylinder 2313 for driving the second inner sleeve 2312 to slide in the second outer sleeve 2311; wherein, one end of the second inner sleeve 2312 extends out of the second outer sleeve 2311 and is fixedly connected to the second telescopic support member 232; the telescopic actions of the second hydraulic cylinder 2313 of the front leg 23 and the rear leg 24 are opposite.

[0039] Here, the second outer sleeve 2311 and the second inner sleeve 2312 are nested with each other to form a sliding fit and are extended and retracted under the drive of the second hydraulic cylinder 2313. When the lateral leg group is suspended, the second hydraulic cylinders 2313 of the front legs 23 and the rear legs 24 move synchronously and in opposite directions to achieve the longitudinal movement of the platform body 10. The action is simple and stable. It should be noted that the second telescopic support member 232 can be a vertically arranged structure that uses the same inner and outer sleeves as the longitudinal telescopic member to drive the hydraulic cylinder, which will not be described in detail here.

[0040] For some possible implementations, see Figure 2 and Figure 3 The water drive assembly 12 includes two power machines 121 and propellers 122 respectively connected to the output ends of the two power machines 121; wherein the two power machines 121 are respectively arranged at the lateral ends or longitudinal ends of the platform body 10, and the two propellers 122 are connected to the bottom of the platform body 10 through a transmission shaft.

[0041] Here, the power machine 121 can be a diesel engine or an electric motor. The power machine 121 drives the propeller 122 extending below the water surface to rotate to produce a water-displacing effect, thereby driving the platform body 10 floating on the water surface to move. Using two power machines 121 to drive two propellers 122 to displace water at the same time can increase the floating movement speed on the water, thereby improving the working efficiency.

[0042] It should be noted that see Figure 2 In this embodiment, two buoys 11 are symmetrically distributed along the horizontal axis of the platform body 10, and the water drive assembly 12 is located between the two buoys 11. The symmetrical arrangement of the two buoys 11 can improve the floating stability of the platform body 10 on the water surface, and placing the water drive assembly 12 between the two buoys 11 can ensure that the driving force of the water drive assembly 12 on the platform body 10 is balanced, thereby improving the stability of movement on water.

[0043] For some examples, see Figure 1 Each support end of the walking support assembly 20 is provided with a ball joint support 201. Since the underwater ground is uneven, the support stability between each support end and the underwater ground can be ensured by providing the ball joint support 201, thereby improving the support state stability of the platform body 10.

[0044] Based on the same inventive concept, an embodiment of the present application also provides a seaweed planting machine, including a seaweed planting machine, including the above-mentioned water mobile platform.

[0045] Compared with the prior art, the seaweed planting machine provided in this embodiment adopts the above-mentioned water mobile platform, which can make the seaweed planting operation not be affected by the tides near the shallow sea coast, thereby solving the time limitation problem of the inability to plant operations during the tidal period and improving the flexibility of the seaweed planting operation time.

[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
