[0045] In addition, it should be noted that in the description of the present utility model, unless otherwise clearly specified and defined, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the communication inside two components. For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0046] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 7 as shown, which are respectively the structure diagrams of another angle, the baffle component, the baffle plate shaft, the baffle plate and the sector-shaped weight block, and the baffle plate of the stone conveying device for marine construction in the embodiment of the present utility model. The stone conveying device for marine construction of the present utility model includes:

[0047] A conveying mechanism for conveying the stones for marine construction to the target unloading position, including a lifting unit for changing the vertical unloading height of the stones.

[0048] A pushing mechanism connected to the conveying mechanism for pushing the stones along the transportation direction to the position to be unloaded, including a moving limit unit for changing the spatial position of the stones when they move within a fixed moving range by pushing the stones and a torque transmission unit connected to the moving limit unit for transmitting the moving torque to the moving limit unit. Among them, the moving limit unit includes a plurality of baffle components 8 for restricting the spatial position of some of the moving stones.

[0049] The operation process of the present utility model is as follows: The conveyor loads the stones, the conveyor motor 1 operates to drive the active scraper chain 6 to start rotating along the stone transportation direction, the baffle plate shaft 81 connects the active scraper chain 6, the driven scraper chain 7, and the baffle plate 82 starts to push the stones in the conveying trough 2 along the stone transportation direction. When the stones are conveyed to near the output end of the lifting rod 4, the stones are ready to fall to another stone conveying device. At this time, the fan blades 3 start to rotate under the influence of the sea wind, the engine generates electricity, the lifting rod 4 is electrified and descends, the angle between the conveying trough 2 and the horizontal plane becomes smaller, the baffle plate 82 is affected by the sector-shaped weight 83 and the angle between the baffle plate 82 and the conveying trough 2 becomes larger, and the stones fall to another stone conveying device; when the sea wind is not sufficient to affect the falling of the stones, the height of the lifting rod 4 rises to the height of the lifting rod 4 before the descent, the angle between the conveying trough 2 and the horizontal plane becomes larger, and the baffle plate 82 is affected by the sector-shaped weight 83 and the angle between the baffle plate 82 and the conveying trough 2 becomes smaller.

[0050] In practice, the utility model provides a loading unit, a pushing mechanism and a lifting mechanism, and provides a torque transmission unit and a plurality of rotatable material blocking components 8. When the stone is transported obliquely upward, the material blocking components 8 slow down the falling of the stone due to the effect of gravity, thereby improving the working efficiency of the stone conveying device; by providing a wind fan, the wind at sea is too strong, which causes the stability of the stone falling to decrease. The wind fan uses the offshore wind power to generate electricity, thereby reducing energy consumption; by providing a lifting rod 4, the lifting rod 4 is powered when the wind fan generates electricity, thereby adjusting the height of the lifting rod 4, thereby increasing the stability of the stone falling.

[0051] Specifically, the conveying mechanism also includes a conveying trough 2 connected to the lifting unit for loading stones.

[0052] Specifically, the conveying mechanism further includes a conveying trough support 9 connected to the conveying trough 2 for supporting the conveying trough 2 .

[0057] Specifically, the torque transmission unit comprises:

[0058] An active scraper chain 6 connected to the conveying trough 2 for changing the transport position of the plurality of material blocking assemblies 8;

[0059] A conveying motor 1, which is connected to the active scraper chain 6 and is used to provide power for the active scraper chain 6 to circulate;

[0060] The driven scraper chain 7 is respectively connected to the conveying trough 2 and the plurality of material blocking assemblies 8 to carry the stone materials.

[0061] Specifically, the conveying motor 1 is arranged on the side of the conveying trough 2. In implementation, those skilled in the art can change the size and material of the conveying trough 2 and the conveying motor 1, as long as the working process of the utility model is realized under the condition that the conveying trough 2 and the conveying motor 1 maintain the relative position relationship specified in the embodiment of the utility model.

[0062] In practice, the utility model increases the loading capacity of the conveying device when loading stones by providing the conveying trough 2 and the conveying motor 1, effectively reduces the leakage of materials during the conveying process, and further improves the working efficiency of the conveying device.

[0063] Specifically, the plurality of baffle components 8 are distributed at equal intervals along the stone transportation direction.

[0064] Specifically, for a single baffle component 8, it includes:

[0065] A baffle shaft 81, which is arranged between the active scraper chain 6 and the driven scraper chain 7, and drives the driven scraper chain 7 to operate in a cycle by transmitting the moving torque of the active scraper chain 6 to the driven scraper chain 7;

[0066] A baffle 82, which is connected to the baffle shaft 81 and is used to dilute the gravity of the stone falling in the reverse direction of the push;

[0067] A baffle sleeve 84, which is connected to the baffle 82 and is used to connect the baffle 82 to rotate around the baffle shaft 81;

[0068] A sector-shaped weight 83, which is arranged in the baffle sleeve 84 and is used to provide a vertically downward additional gravity for the baffle 82 to keep the baffle 82 in a vertical state.

[0069] In practice, the material of the sector-shaped weight 83 can be selected from lead and platinum.

[0070] In practice, the utility model realizes the increase of the continuity of stone transportation by setting the baffle shaft 81 to connect and balance the active scraper chain 6 and the driven scraper chain 7, reducing the deviation or vibration during operation; realizes the improvement of the material conveying efficiency and the reduction of stone loss by setting the baffle 82; realizes the reduction of stone loss and the improvement of the working efficiency of stone transportation by setting the sector-shaped weight 83 to increase the force in the gravity direction for the baffle 82 and keep the baffle 82 always in a state coinciding with the gravity direction.

[0072] Fan blades 3, which are arranged above the conveying trough 2 and are used to convert wind energy into mechanical energy;

[0073] A fan frame 5, which is connected to the fan blades 3 and is used to support the fan blades 3.

[0074] Specifically, the fan further includes a gearbox (not marked in the figure) that is respectively connected to the fan blades 3 and is used to transmit mechanical energy.

[0075] Specifically, the relative spatial positions of the fan blade 3, the fan frame 5, and the lifting rod 4 are preferred embodiments of the present utility model. During implementation, those skilled in the art can change the sizes and materials of the fan blade 3, the fan frame 5, and the lifting rod 4, as long as the working process of the present utility model can be achieved under the condition that the relative positional relationship defined by the embodiments of the present utility model for the fan blade 3, the fan frame 5, and the lifting rod 4 is maintained.

[0076] During implementation, the present utility model converts offshore wind power into electrical energy by setting up the fan blade 3 and the fan frame 5, achieving a reduction in energy consumption. Since the falling of the stone is affected by the wind force and there is a loss during the falling process of the stone, the fan blade 3 consumes the wind force towards the output end, achieving an increase in the stability of the stone falling.

[0077] Specifically, the generator 10 is also used to supply power to the lifting rod 4 after the fan blade 3 starts to rotate.

[0078] During implementation, the lifting rod 4 is an electric lifting rod 4. The lifting control process of the electric lifting rod 4 is a conventional technical means well-known to those skilled in the art, and the lifting process of the electric lifting rod 4 will not be elaborated further.

[0079] During implementation, the present utility model generates electricity by the engine when the fan blade 3 rotates, the lifting rod 4 is electrified, and then the height of the lifting rod 4 decreases, thereby reducing the falling height of the stone, reducing the loss of the stone caused by the wind force, and further achieving an increase in the stability of the stone falling.

[0080] During implementation, when the wind pressure received by the fan blade 3 increases, the rotation speed of the fan blade 3 increases, and the height of the lifting rod 4 decreases.

[0081] Specifically, the length of the sector-shaped weight 83 is less than the length of the baffle sleeve 84.

[0082] Specifically, the sector-shaped weight 83 is movably sleeved inside the baffle sleeve 84.

[0083] Specifically, the size of the sector-shaped weight 83 is determined according to the diameter of the baffle shaft 81 and the inner contour size of the baffle 82.

[0084] During implementation, the sum of the gravity of the sector-shaped weight 83 and the baffle assembly 8 and the component force along the moving direction of the stone is greater than or equal to the component force along the moving direction of the maximum weight of the stone borne by the transfer groove 2 between two adjacent baffle assemblies 8.

[0085] Specifically, the lower surface of the baffle 82 is tangent to the upper surface of the transfer groove 2.

However, it is easily understood by those skilled in the art that the protection scope of the present utility model is obviously not limited to these specific embodiments. Without departing from the principle of the present utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of the present utility model.
