[0002] As a renewable energy source with abundant sources and no pollution, the development and utilization of wave energy has received extensive attention from governments and scientific research institutions around the world. As the core carrier for converting ocean energy into electrical energy, wave energy power generation equipment is of great significance in achieving sustainable development goals, reducing dependence on traditional energy, reducing greenhouse gas emissions, providing relatively stable power output, and reducing the impact on the power grid.

[0003] The working stability and reliability of wave energy power generation equipment are key factors for its efficient operation. However, in actual operation, it may be affected by various factors such as extreme weather, changes in sea conditions, equipment aging, etc., and face risks such as excessive shaking, damage, and even failure. Therefore, a well-designed risk avoidance and maintenance mechanism is an important means to ensure the stable and reliable operation of wave energy power generation equipment.

[0004] The existing risk avoidance and maintenance mechanisms focus on how to protect the equipment from external risks, but the risk avoidance and maintenance mechanism settings for internal fault maintenance of wave energy power generation equipment, especially when internal maintenance is required, are still insufficient; when an internal fault occurs in wave energy power generation equipment, maintenance cannot be carried out safely and efficiently, and the float position and sinking adjustment cannot be effectively fixed, resulting in poor overall safety and reliability of maintenance. Summary of the invention:

[0005] The embodiment of the present invention provides a risk avoidance and maintenance mechanism for wave energy power generation equipment based on controllable ballast. The structure is reasonably designed. Based on the mutual cooperation of multiple functional components, when maintenance is needed, the float can be easily pulled to the uppermost end through manual operation, and the float can be ensured to remain fixed during the maintenance process by locking the winch mechanism to avoid the float from floating up and down due to wave movement, thereby reducing the risk and difficulty of internal maintenance work of wave energy power generation equipment and equipment recovery, significantly improving the safety and reliability of wave energy power generation equipment in risk avoidance and maintenance projects, effectively avoiding equipment damage, reducing maintenance costs, extending the service life of equipment, and reducing the risk of personal injury due to equipment failure or extreme weather, thereby solving the problems existing in the prior art.

When it is monitored that the environmental parameters exceed the preset safety threshold, or the equipment has a fault warning, the system will automatically trigger the risk avoidance process and quickly adjust the buoyancy of the float 3. Under extreme weather conditions, the ballast volume is increased to make the float 3 sink to a safe underwater depth to avoid damage due to wave impact. In the event of equipment failure, the ballast volume is adjusted to fix the float and the power generation equipment connected to it in a stable position. During the risk avoidance and maintenance process, the position of the float is locked to prevent it from moving due to external factors. At the same time, the system will continue to monitor the risk avoidance status to ensure that the float and the power generation equipment connected to it are in a safe state.

[0052] The float external water pump system includes an external water pump 9 and a portable water hose 2, wherein the external water pump is fixed to the float by bolts; there are two portable water hoses, wherein the head end of one water hose is connected to the water inlet of the float, and the tail end is connected to the water outlet of the external water pump; the head end of the other water hose is connected to the water inlet of the external water pump, and the tail end is connected to the sea water.

[0053] The anchoring system includes an anchor winch 11, an anchor chain 6 and a heavy anchor 7; the anchor winch 11 is two in number and is respectively installed inside the bottom damping plate 5; the heavy anchor 7 is placed on the seabed, and the wave energy power generation equipment is connected to the heavy anchor 7 through the anchor chain 6.

[0054] The internal ventilation system includes an axial flow fan 12 and a waterproof window. The axial flow fan 12 can be started by remote control. After the internal air is circulated, maintenance personnel can enter the interior for maintenance. In addition, when manual maintenance is not required, the axial flow fan can effectively dissipate heat from the internal devices of the power generation equipment, so that all parts are at the optimal working temperature, thereby improving work efficiency and extending the service life of the equipment.

[0055] The lighting system comprises a lighting lamp 13 and a lamp stand, and the lighting lamp is powered by wave energy power generation equipment.

[0056] The winch transport system includes a winch 14, a hook 16, a lifting rope 15 and a winch track plate. The winch 14 is a core driving device, which ensures stable and accurate power output during operation through a specific motor drive system.

[0059] The risk avoidance and maintenance method of the mechanism comprises the following steps:

[0060] S1, open the waterproof window on the upper layer of the axial flow fan installed on the top of the buoy, and start the axial flow fan remotely;

[0061] S2: After the internal air circulates, the maintenance personnel use the internal ladder to enter the interior for maintenance;

[0062] S3, turn on the lighting system and use the winch transportation system to inspect locations at different heights;

[0063] S4, remote control hook 16 and lifting rope 15 are raised and lowered to transport parts and tools, which improves maintenance efficiency and reduces maintenance time.

[0064] The working principle of a risk avoidance and maintenance mechanism for wave energy power generation equipment based on controllable ballast in an embodiment of the present invention is as follows: based on the mutual cooperation of multiple functional components, when maintenance is required, the float can be easily pulled to the uppermost end through manual operation, and the float can be ensured to remain fixed during the maintenance process by locking the winch mechanism to avoid the float from floating up and down due to wave movement, thereby reducing the risk and difficulty of internal maintenance work of the wave energy power generation equipment and equipment recovery, significantly improving the safety and reliability of the wave energy power generation equipment in risk avoidance and maintenance projects, effectively avoiding equipment damage, reducing maintenance costs, extending the service life of the equipment, and reducing the risk of personal injury due to equipment failure or extreme weather.

[0065] Compared with traditional avoidance and maintenance mechanisms, the present application can effectively fix the position of the float when the equipment is recovered, and simultaneously perform sinking adjustment to improve the safety of internal maintenance.

[0066] In order to realize the sinking adjustment function of the device, the present invention uses a water pump to add water and increase the pressure inside the float, so as to increase the weight of the float, reduce the buoyancy of the float, and then cause the entire device to sink to an appropriate depth; in this process, the anchor chain is wound by a winch, and the structural form of the anchor chain can be flexibly adjusted to adapt to the fixing requirements under different sea conditions and bottom conditions, so that the device can be adaptively adjusted according to the actual sea conditions, thereby improving the stability and reliability of the device.

[0067] The present application can perform both internal and external maintenance. For the scenario of internal maintenance of equipment, the present invention installs axial flow fans at the upper and bottom ends of the device, which not only helps to quickly exhaust air during the maintenance process and maintain the internal air pressure balance, but also improves the ventilation and heat dissipation effects; at the same time, a complete lighting system is installed to ensure that maintenance personnel can have a clear view even in a dim environment and perform various maintenance operations safely and efficiently; in addition, a winch transportation system is also configured at key internal locations to quickly transport large parts or tools when necessary, further improving the convenience and safety of internal maintenance work.

[0068] For the scenario of external maintenance of equipment, a connecting trestle is set up to facilitate the staff to land on the equipment for maintenance when the device floats up and down. The trestle is designed with a wave compensation device to offset the up and down floating and left and right swaying of the trestle caused by waves, ensuring the stability and safety of personnel when walking on the trestle.

[0069] This application significantly improves the safety and reliability of wave energy power generation equipment in risk avoidance and maintenance projects through the innovative design of the above-mentioned multi-type functional components. It not only solves the key technical problems that have long plagued the development of the wave energy power generation industry, but also injects new vitality and impetus into the development of new energy technologies.

[0070] In the overall scheme, the mechanism includes: a movable pulley block labor-saving winch, installed on the float and the pontoon, used to realize the lifting and lowering control of the float; a float external water pump system, connected to the float, used to pump seawater into or out of the float to provide a stable and controllable weight ballast for the float; an anchoring system, installed inside the bottom damping plate of the wave energy power generation equipment, used to fix the wave energy power generation equipment; an internal ventilation system, used to provide a good ventilation environment inside the wave energy power generation equipment; a lighting system, used to provide sufficient lighting conditions inside the wave energy power generation equipment; a winch transportation system, used to transport parts and tools; a monitoring and early warning system, used to monitor environmental parameters and the equipment's own operating status in real time. Environmental parameters include at least wave height, wind speed and water flow speed. Multiple types of high-precision sensors are integrated in the monitoring and early warning system. When the monitored environmental parameters exceed the preset safety threshold, or the equipment has a fault warning, the system will automatically trigger the risk avoidance process and quickly adjust the buoyancy of the float. In extreme weather conditions, the ballast volume is increased to make the float sink to a safe underwater depth to avoid damage due to wave impact. In the event of equipment failure, the ballast volume is adjusted to fix the float and the power generation equipment connected to it in a stable position. During the risk avoidance and maintenance process, the position of the float is locked to prevent it from moving due to external factors. At the same time, the system will continue to monitor the risk avoidance status to ensure that the float and the power generation equipment connected to it are in a safe state.

[0071] For the movable pulley block labor-saving winch, it is possible to realize the lifting and lowering control of the float with labor-saving, so as to facilitate the pumping of seawater into or out of the float and provide a stable weight ballast for the float.

[0072] The float external water pump system includes an external water pump and a portable water hose, wherein the external water pump is fixed to the float by bolts; there are two portable water hoses, wherein the head end of one water hose is connected to the water inlet of the float, and the tail end is connected to the water outlet of the external water pump; the head end of the other water hose is connected to the water inlet of the external water pump, and the tail end is connected to seawater, so as to facilitate maintenance work, and the buoyancy of the float can be easily adjusted. At the same time, it can be conveniently disassembled and installed as needed, so as to facilitate the recovery of the device.

[0073] The anchoring system of the present application can effectively fix the entire power generation equipment to keep it stable in the waves. At the same time, the anchor winch can flexibly adjust the structural form of the anchor chain. By adjusting the length of the anchor chain, the force of each anchor chain is distributed according to the actual situation, and the equipment posture is adjusted to adapt to application scenarios with different sea conditions to ensure the smooth operation of the equipment. The mooring state of the wave energy power generation equipment can be flexibly adjusted to make the anchor chain evenly stressed, which not only improves the stability of the system, but also effectively reduces the difficulty of operation, allowing the equipment to be quickly deployed and recovered.

[0074] In contrast to the lighting system and ventilation system of this application, in order to ensure internal air circulation, the maintenance personnel open the waterproof window on the axial flow fan installed on the top of the buoy and start the fan remotely; after the internal air circulation, the maintenance personnel can enter the interior for maintenance; in addition, when no manual maintenance is required, the axial flow fan can effectively dissipate heat from the internal devices of the power generation equipment, so that each part is at the optimal working temperature, improve work efficiency and extend the service life of the equipment; the lighting system can make full use of the clean energy generated by the wave power generation equipment to achieve green energy saving, efficient and bright lighting effects; when the maintenance personnel need to perform lighting operations inside or around the equipment, start the lighting system that is tightly fixed to the inner wall of the buoy and well sealed. The design of this lighting system not only ensures that the light source is evenly distributed, avoiding the problem of excessive or insufficient lighting, but also its controllability allows the brightness to be adjusted according to actual needs.

[0075] When the device needs to be overhauled, the float is manually pulled to the top by a movable pulley winch installed on the float and the pontoon to lock it, preventing the float from moving up and down during the overhaul. Then, water is added to the inside of the float using a pump in the float's external water pump system to increase the float's weight and press it onto the pontoon, causing the entire device to sink and improve the device's stability. At the same time, the anchoring system in the bottom damping plate is manually remotely controlled, using a winch to wind the anchor chain to adjust the configuration of the anchor chain, and to adjust the draft and tide level of the wave energy power generation equipment to adapt to it.

[0076] In actual application, the real-time monitoring link of the monitoring early warning system is also needed. Through the integration of multiple types of high-precision sensors, environmental parameters such as wave height, wind speed, water flow speed, and the operating status of the equipment itself can be monitored in real time.

[0077] Specifically, when the monitored environmental parameters exceed the preset safety threshold, or the equipment has a fault warning, the system will automatically trigger the risk avoidance process; according to the actual risk avoidance needs and application scenarios, the system will quickly adjust the buoyancy of the float.

[0078] Under extreme weather conditions, such as typhoons and huge waves, the system will increase the ballast volume to allow the float to sink to a safe underwater depth to prevent it from being damaged by wave impact. In the event of equipment failure, such as motor overheating or cable breakage, the system will also adjust the ballast volume to fix the float and the power generation device connected to it in a stable position for subsequent maintenance. During risk avoidance or maintenance, the system will lock the position of the float to prevent it from moving due to external factors. At the same time, the system will continue to monitor the risk avoidance status to ensure that the float and the power generation device connected to it are in a safe state.

[0079] In order to facilitate external maintenance, a docking trestle is also required to facilitate workers to land on the equipment for maintenance when the device floats up and down; further, an adjustable support structure telescopic device is also provided on the docking trestle to offset the up and down floating and left and right swaying of the docking trestle caused by waves, ensuring the stability and safety of workers when walking on the docking trestle.

[0080] Generally speaking, the structural design of the pier needs to have sufficient strength and durability to withstand long-term wave impact and corrosion; the overall material is made of high-strength steel and anti-corrosion coatings to improve the corrosion resistance and service life of the pier; the pier is designed with anti-slip, anti-fall and other safety measures, as well as comfortable walking space and safety guardrails to improve the safety and comfort of personnel.

[0081] During the internal maintenance process of the device, it is first necessary to open the waterproof window installed on the upper layer of the axial flow fan on the top of the pontoon, and start the fan remotely; after the internal air circulates, the maintenance personnel can use the internal ladder to enter the interior for maintenance, turn on the lighting system fixed to the inner wall of the pontoon, and use the winch transportation system installed on the top of the pontoon for maintenance at different heights. The winch composed of a winch hook, a lifting rope, and a winch track plate runs on a specific winch track plate and remotely controls the lifting of the hook and the lifting rope to transport parts and tools, which greatly improves the maintenance efficiency, reduces the maintenance time, and ensures the safety of the maintenance personnel.

[0082] It is further explained that the present application uses a labor-saving winch mechanism of a movable pulley block, which can easily pull the float to the top through manual operation, and firmly lock the winch through a special device, so that the float can be stably stopped at the specified position. In this way, during the inspection and recovery process, the up and down movement of the float can be effectively avoided, ensuring the safety and smooth progress of the operation; in order to further increase the weight of the float, the present invention adopts a float external water pump system, which effectively increases its weight by adding water to the inside of the float. Doing so can not only make the float firmly pressed on the buoy, but also cause the entire device to sink to the desired position.

[0083] This application can ensure the stability and reliability of the risk avoidance function through mechanisms such as real-time monitoring and early warning, controllable ballast adjustment, and safety locking; and can flexibly adjust the buoyancy state of the float according to different risk avoidance needs to adapt to different environmental conditions and equipment conditions; by effectively avoiding equipment damage, the system can reduce maintenance costs and extend the service life of the equipment. The risk avoidance function not only protects the equipment from damage, but also ensures the safety of operation and maintenance personnel, reduces the risk of personal injury caused by equipment failure or extreme weather, and improves the overall safety of wave energy applications.

[0084] To sum up, a risk avoidance and maintenance mechanism for wave energy power generation equipment based on controllable ballast in an embodiment of the present invention is based on the mutual cooperation of multiple functional components. When maintenance is required, the float can be easily pulled to the uppermost end through manual operation, and the float can be ensured to remain fixed during the maintenance process by locking the winch mechanism, thereby avoiding the up and down floating of the float due to wave movement, thereby reducing the risk and difficulty of internal maintenance work of wave energy power generation equipment and equipment recovery, significantly improving the safety and reliability of wave energy power generation equipment in risk avoidance and maintenance projects, and can effectively avoid equipment damage, reduce maintenance costs, extend the service life of equipment, and reduce the risk of personal injury caused by equipment failure or extreme weather.

[0085] The above specific implementation manner cannot be used as a limitation on the protection scope of the present invention. For those skilled in the art, any substitution, improvement or change made to the implementation manner of the present invention falls within the protection scope of the present invention.
