Description

Technical Field

[0001] The present invention belongs to the technical field of offshore wind power operation and maintenance, and in particular relates to a multifunctional offshore wind power inspection ship. Background Art

[0002] The operation and maintenance of offshore wind farms requires comprehensive consideration of factors such as offshore distance, weather and sea conditions, unit failure rate, maintenance behavior, power generation capacity, and operation and maintenance economy to configure the operation and maintenance ship. Offshore wind power operation and maintenance ships are special ships used for the operation and maintenance of offshore wind turbines. The ship should have good movement performance in waves, be able to berth accurately at low speed to the foundation of the wind turbine to prevent a large impact on the foundation, and be able to maintain continuous contact with the foundation.

[0003] Generally speaking, large-scale wind farms adopt fleets, such as high-speed maintenance ships, professional maintenance ships, residential ships, jack-up maintenance ships and other special engineering ships. The general principle of maintenance ship configuration is: ordinary maintenance ships are used when the weather is good and close to the shore, advanced professional maintenance ships are used when the weather is complex and close to the shore, ordinary maintenance ships or professional maintenance ships and maintenance mother ships are used when the weather is good and far from the shore, and professional maintenance ships and maintenance mother ships are used when the weather is complex and far from the shore.

[0004] Offshore wind turbines are installed on the sea surface through bottom fixed supports and suspended supports. When inspecting the parts below the sea surface and the upper part of the wind turbine, it is necessary to dive and climb. However, the weather at sea changes rapidly. When the wind and waves are strong, diving or climbing operations will pose a great safety hazard. In addition, the existing operation and maintenance ships, due to their numerous functions and large size, often cost a lot to go out to sea. At the same time, their maneuverability is greatly limited, and they lack flexibility and cannot find problems in time. Summary of the invention

[0005] In order to solve the defects existing in the above-mentioned prior art, the purpose of the present invention is to provide a multifunctional offshore wind power inspection vessel with reasonable functional design, which can effectively improve the maneuverability, flexibility and economy of routine inspections, while ensuring the personal safety of workers in severe weather.

[0006] The present invention is achieved through the following technical solutions:

[0007] The invention discloses a multifunctional offshore wind power inspection ship, comprising a motor, a fuel engine, a solar energy storage panel, an energy storage battery pack, a transmission system, a propulsion device, a drone fixing plate, a drone, a diving robot cabin and a diving robot;

[0008] The transmission system is respectively connected to the motor, the fuel engine and the propulsion device, the motor is connected to the energy storage battery pack, and the energy storage battery pack is connected to the solar energy storage panel; the diving robot is loaded in the diving robot cabin, and the diving robot cabin is connected to the energy storage battery pack;

[0009] The UAV fixing plate is movably connected to the stern of the multifunctional offshore wind power inspection ship; when the multifunctional offshore wind power inspection ship is sailing, the UAV fixing plate is perpendicular to the sea surface, the UAV is connected to the energy storage battery pack, the UAV is fixed on the UAV fixing plate, and the propeller of the UAV serves as the propulsion device of the multifunctional offshore wind power inspection ship; when the UAV performs an inspection task, the UAV fixing plate is parallel to the sea surface.

[0010] Preferably, the drone includes an infrared image acquisition device.

[0011] Preferably, an infrared image acquisition device and a sonar detection device are provided in the middle of the diving robot, and a propeller is provided at the bottom.

[0012] Preferably, a control system is provided in the cockpit of the submersible robot, and the submersible robot is connected to the cockpit of the submersible robot via a connecting cable.

[0013] Preferably, the energy storage battery pack is provided with a power display device and a low power alarm device.

[0014] Preferably, the solar energy storage panels are arranged on the deck and hull surface of the multifunctional offshore wind power inspection vessel.

[0015] Compared with the prior art, the present invention has the following beneficial technical effects:

[0016] The present invention discloses a multifunctional offshore wind power inspection ship. When the sunlight is strong, the inspection ship can adopt a pure solar energy mode, and the solar energy storage panel collects electricity to provide power for the inspection ship. At the same time, there is also a complete and mature plug-in hybrid system in the hull. When the sunlight is not strong, the fuel engine is responsible for providing power. Since the motor work efficiency in the starting and acceleration stages is higher than that of relying solely on traditional fuel engines, it is only necessary to ensure that the fuel generator is always kept in an efficient charging condition to power the motor. The motor divides the energy into two paths, one side is transmitted to the energy storage battery group in the hull to charge the energy storage battery group, and the other side transmits the electricity to the drone fixed vertically at the stern. After the battery and blade motor of the drone obtain electricity, it is converted into the electricity of the drone battery and the kinetic energy of the drone propeller. The propeller is inserted into the water to provide kinetic energy for the inspection ship. When the sunlight is not strong and the fuel is insufficient, the energy storage battery group begins to discharge, and the inspection ship enters the pure electric mode, which is powered by the energy storage battery group. Multiple energy supply methods enable the inspection ship to adapt to different working conditions, greatly extending the cruising time and cruising distance, and high flexibility. In severe weather conditions, drones and submersible robots can be used to conduct inspections at heights and under the sea, eliminating the need for manual climbing and diving, saving labor costs and ensuring the personal safety of staff.

[0017] Furthermore, the infrared image acquisition device equipped on the drone can capture images when there is insufficient light or bad weather.

[0018] Furthermore, the submersible robot is equipped with an infrared image acquisition device and a sonar detection device, which can carry out various inspection operations under the sea surface where light is insufficient. The propeller provides diving power and ascent thrust, and reliable temperature.

[0019] Furthermore, the traction rope in the connecting cable can prevent the submersible robot from being lost, the electrical cable can continuously provide power and increase the endurance time, and the optical cable can control the submersible robot and transmit the collected information back to the control system in a timely manner.

[0020] Furthermore, the energy storage battery pack is provided with a power display device and a low power alarm device, which enables the operator to grasp the battery power at any time and take effective measures according to the situation when the power is low to ensure the stability and safety of the operation.

[0021] Furthermore, solar energy storage panels are arranged on the deck and hull surface of the plug-in hybrid inspection ship, which can increase the light coverage area and improve the utilization rate of light energy. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments, the contents of which are intended to explain the present invention rather than to limit it:

[0029] like Figure 1 The present invention provides a multifunctional offshore wind power inspection ship, in which a complete and mature plug-in hybrid power system is arranged in the hull; including a motor 1, a fuel engine 2, a solar energy storage panel 3, an energy storage battery pack 4, a transmission system 5, a propulsion device 6, a UAV fixing plate 7, a UAV 8, a diving robot cabin 9 and a diving robot 10; the solar energy storage panel 3 is arranged on the deck and the hull surface of the multifunctional offshore wind power inspection ship.

[0030] The transmission system 5 is connected to the motor 1, the fuel engine 2 and the propulsion device 6 respectively. The motor 1 is connected to the energy storage battery pack 4. The energy storage battery pack 4 is connected to the solar energy storage panel 3. The energy storage battery pack 4 is provided with a power display device and a low power alarm device.

[0031] like Figure 4 The diving robot 10 is loaded in the diving robot cabin 9. An infrared image acquisition device and a sonar detection device are arranged in the middle of the diving robot 10. A propeller is arranged at the bottom. The diving robot cabin 9 is connected to the energy storage battery pack 4. A control system is arranged in the diving robot cabin 9. The diving robot 10 is connected to the diving robot cabin 9 through a connecting cable. The connecting cable includes a traction rope, an electrical cable and an optical cable integrated in the waterproof layer. The optical cable is connected to the control system.

[0032] like Figure 2 , Figure 3 and Figure 5The drone fixing plate 7 is movably connected to the stern of the multifunctional offshore wind power inspection ship; when the multifunctional offshore wind power inspection ship is sailing, the drone fixing plate 7 is perpendicular to the sea surface, the drone 8 is connected to the energy storage battery pack 4, and the drone 8 is fixed on the drone fixing plate 7 by a lock. The drone 8 is equipped with an infrared image acquisition device, and the propeller of the drone 8 serves as a propulsion device of the multifunctional offshore wind power inspection ship; when the drone 8 performs an inspection task, the drone fixing plate 7 is parallel to the sea surface.

[0033] The working principle of the multifunctional offshore wind power inspection ship of the present invention is as follows:

[0034] The primary power source of the multifunctional offshore wind power inspection ship is solar energy, which is clean and environmentally friendly. In addition, offshore wind power solar energy resources are abundant and inexhaustible. In order to overcome the impact of weather and nighttime on solar energy, the hull introduces a plug-in hybrid system, which greatly improves the adaptability of the multifunctional offshore wind power inspection ship under different working conditions.

[0035] Compared with traditional engines, many working conditions are not optimal (such as starting, accelerating, braking, etc.). This results in low working efficiency and environmental protection. Therefore, it is designed that the motor 1 directly drives the propeller to provide power. The output of the motor 1 has no time lag and low efficiency. The fuel engine 2 only needs to ensure that it works under the optimal working conditions to provide electrical energy for the motor 1.

[0036] The multifunctional offshore wind power inspection vessel can not only carry out daily rapid inspections according to the prescribed inspection routes, but also because of its small size and strong maneuverability, it can be used in conjunction with a remote control device as an unmanned inspection vessel to quickly reach the scene in case of emergency or when it is not suitable for manual sea inspections.

[0037] When the multifunctional offshore wind power inspection ship arrives at the designated location and the drone 8 needs to fly, the vertical drone fixing plate 7 at the stern is lifted upward to make it parallel to the sea level, forming a small take-off platform, and the locks fixed around the drone 8 are unlocked, and the drone 8 takes off. After completing the flight inspection mission, the aircraft follows the signal sent from the helipad and lands on the drone fixing plate 7. The locks around it re-lock the drone 8, and the drone fixing plate 7 falls down, and the propeller of the drone 8 becomes a hull propeller.

[0038] When the multifunctional offshore wind power inspection ship arrives at the designated location and needs to dive for detection, the towing rope on the top of the submersible robot 10 located at the bottom of the ship is lowered, and power is provided to the submersible robot 10 through a cable. The submersible robot 10 falls into the water and, driven by the positive transmission of the bottom propeller, quickly dives to the designated location to complete the designated task. The collected data is transmitted back to the control system in the hull through the optical cable in the towing rope. The propeller at the bottom of the submersible robot 10 reverses to provide lifting force, and the towing rope is tightened circle by circle to lift the submersible robot 10 upward.

[0039] The multifunctional offshore wind power inspection ship of the present invention uses a rotatable drone fixing plate 7 to replace the propeller of the traditional ship with the propeller of the drone 8, which can effectively reduce the weight of the hull and reduce the size of the hull. The submersible robot 10 solves the power problem of ascent and descent through the forward and reverse rotation of the small propeller, and also reduces the weight, leaving more space for combining more functional modules, while providing energy, returning data and recovering the lift through the traction rope.

[0040] It should be noted that the above is only one of the embodiments of the present invention, and equivalent changes made to the system described in the present invention are all included in the protection scope of the present invention. Those skilled in the art of the present invention can make similar substitutions for the specific examples described, as long as they do not deviate from the structure of the present invention or exceed the scope defined by the claims, they are all within the protection scope of the present invention.
