Description

Technical Field

[0001] The utility model relates to the technical field of marine energy, in particular to a power generation device based on a cage moored buoy. Background Art

[0002] With the rapid increase in energy consumption in countries around the world, the development and utilization of renewable clean energy has become an important way to solve the energy problem. The waves in the ocean contain huge energy, and they cause marine structures such as cages in the ocean to produce motion responses. If this energy can be used and recycled to generate electricity and provide electricity for the production operations of marine structures, it can improve economic benefits and achieve green development of marine resources.

[0003] At present, the power demand of marine aquaculture cages mainly depends on external power supply, such as connecting to the power grid or using small generators to provide the necessary power to realize the monitoring, feeding and other functions in aquaculture. Therefore, due to energy constraints, the working range of marine aquaculture cages is generally limited to the area near the offshore continent, which makes it difficult to fully utilize marine resources. In actual practice, in addition to functional modules, aquaculture cages also have a mooring system for positioning. The overall mooring system mainly includes structures such as buoys, cables and anchors.

[0004] In summary, existing floating seawater aquaculture cages are limited by their own energy supply and are difficult to adapt to the technical requirements of the offshore operating environment. Utility Model Content

[0005] The technical problem to be solved by the utility model is that the existing floating seawater aquaculture cages are limited by their own energy supply and are difficult to adapt to the requirements of the offshore operating environment.

[0006] To solve the above problems, the utility model provides a power generation device based on a cage-moored buoy, comprising a buoy, an upper mooring cable and a lower mooring cable respectively connected to both ends of the buoy, the upper mooring cable being connected between the buoy and a working module float, the buoy being in the shape of a hollow shell, a power generation assembly being arranged inside the buoy, the power generation assembly comprising a rotating power generation main shaft and a generator, the upper mooring cable being elastically connected to the rotating power generation main shaft by an elastic component, the elastic component converts the pulling force caused by waves and inertia into elastic potential energy, and the elastic potential energy is converted into the rotational motion of the rotating power generation main shaft, and the rotational motion drives the generator to rotate and generate electricity.

[0007] The mooring ball power generation device provided by the utility model can utilize the volume of the mooring buoy itself to set up a power generation component inside. The mooring ball is a hollow shell structure, and has a generator and a driving machine rotating power generation component inside. Specifically, the elastic component is pulled by the cable of the mooring system itself, and the elastic potential energy is accumulated by the elastic component and converted into the rotational motion of the rotating power generation main shaft. Because in the actual application of the mooring system, under the action of waves, the buoy constantly moves relative to the working module buoy. Due to the inertia of the buoy itself, the size and direction of the traction force of the cable on the buoy will constantly change. The elastic component is repeatedly stretched and reset under the action of the cable, that is, the elastic potential energy is accumulated and released repeatedly, so as to achieve the effect of utilizing waves to generate electricity by itself, and the functional requirements of the working module buoy connected to the mooring system are met by self-generation. Here, the working module buoy can be aquaculture cages or other forms of offshore floating operation platforms, which effectively solves the technical problem that the existing floating seawater aquaculture cages are limited by their own energy supply and are difficult to adapt to the requirements of the offshore operation environment.

[0008] As a preferred solution, the elastic member is a spring wound on the rotating power generation main shaft, one end of the spring is connected and fixed to the circumference of the rotating power generation main shaft, and the other end of the spring is used to connect to the upper mooring cable. This design further optimizes the structural design of the elastic member, which is a spring-type spring force storage structure, which is wound on the rotating power generation main shaft, and the two ends are respectively connected to the outer circumference of the cable and the rotating power generation main shaft, which can more easily convert the tension work of the cable into the rotational motion of the rotating power generation main shaft; it should also be noted that the main structure of the spring includes but is not limited to a spiral spring structure with multiple turns connected as one.

[0009] As a preferred solution, a fairlead hole is provided on the shell surface of the buoy, and the end of the upper mooring cable is connected to a secondary generating cable, which passes through the fairlead hole and is connected and fixed to the end of the spring. This design optimizes the connection design between the upper mooring cable and the end of the spring. Since the upper mooring cable may have a larger thickness and diameter due to its own function, as well as other external features that are not suitable for connecting spring parts, in order to ensure that the connection between the cable and the spring is strong and durable and adapts to the structure of the buoy, a secondary generating cable is specially provided at the end of the upper mooring cable for connection. The secondary generating cable has a thickness suitable for connecting the spring, and has a large rigidity to avoid the conversion of the pulling work into its own elastic potential energy. The fairlead hole on the buoy can effectively guide and correct the angle of the secondary generating cable, so that the pulling direction is suitable for the deformation and accumulation of potential energy of the pulling spring.

[0010] As a preferred solution, the auxiliary generating cable is provided with a raised limiting structure protruding from its outer circumference, and the diameter of the raised limiting structure is larger than the aperture of the fairlead hole, so as to limit the maximum tensor of the spring. This design optimizes the matching structure between the auxiliary generating cable and the fairlead hole, and a raised limiting structure is provided at an appropriate position on it. Through the limiting matching of this structure and the fairlead hole, the pulling limit position of the auxiliary generating cable can be limited, so as to avoid the spring spring from exceeding the deformation limit and being damaged.

[0011] As a preferred solution, a sealing partition is provided inside the float, the generator is located on one side of the sealing partition, the rotating power generation main shaft passes through the sealing partition, the spring and the auxiliary power generation cable are located on the other side of the sealing partition, and the sealing partition is used to prevent water from entering the space where the generator is located.

[0012] As a preferred solution, the space between the sealing partition and the outer shell of the float is filled with a light buoyancy filler. This design optimizes the structural design of the position in the float that plays a buoyancy role. The light buoyancy filler is set in the space inside the float on the other side opposite to the generator. The light filling structure can play a certain structural support and space filling effect, avoiding water ingress into the empty space inside the float, causing the buoyancy of the float to fail.

[0013] As a preferred solution, a waterproof casing is provided on the periphery of the generator, a fixed base for supporting and fixing the generator is provided inside the waterproof casing, and a connecting sleeve is provided at the shaft end of the generator, which is connected and fixed to the rotating power generation main shaft through the connecting sleeve. This design optimizes the surrounding structural design of the generator, and a waterproof casing structure surrounding the generator is provided. In order to ensure the stability of the position of the generator in the float and avoid vibration and other situations that affect the normal operation of the generator, a fixed base structure is provided to specifically position the generator, and the coupling function is realized through the connecting sleeve.

[0014] As a preferred solution, the rotating power generation main shaft is provided with a shaft end support member at one end away from the generator, and the shaft end support member includes a support sleeve, and the support sleeve is rotatably supported and connected to the rotating power generation main shaft, and the outer side of the support sleeve is provided with a support seat structure for connecting and fixing with the inner shell surface of the float. This design optimizes the support structure of the rotating power generation main shaft, and the structure of the support sleeve and the support seat structure can limit the stable position of the rotating power generation main shaft in the float, and can ensure its normal rotation work.

[0015] As a preferred solution, a balancing weight structure is provided in the shell space of the buoy on one side of the shaft end support member to adapt to the deadweight of the generator and keep the floating posture of the buoy stable. This design optimizes the balance design of the buoy, and a balancing weight is provided at the other end of the buoy opposite to the generator.
