Description
Technical Field
[0001] The present invention relates to the field of ocean observation technology, and in particular to a tooling and a testing system for oscillating float type wave energy power generation equipment. Background Art
[0002] Since some assembly and testing are required in the research and development of oscillating float wave energy power generation equipment (hereinafter referred to as wave energy power generation equipment), but due to the particularity of wave energy power generation equipment, if there is no special tooling and testing system during its assembly and testing process, it is difficult to complete the tooling tasks and collect test data well by relying only on large general equipment such as cranes and large cranes inside the factory.
[0003] The assembly of wave energy power generation equipment involves mechanical structures and hydraulic systems, which usually need to be tested under wave conditions that simulate the marine environment to ensure that they can operate stably in the actual marine environment. Although the large general equipment in the factory can assist in the assembly process to a certain extent, it lacks adaptability to the unique requirements of wave energy power generation equipment.
[0004] At present, patent No. CN2021109126325 discloses a debugging tooling and debugging method for a deep-sea wave energy power generation device. The debugging tooling has a simple structure, is easy to use, and saves space. It can meet the requirements for systematic debugging of deep-sea wave energy power generation devices on land while having low use costs. In addition, the debugging method can also complete the debugging work of deep-sea wave energy power generation devices on land.
[0005] During the factory tooling test, since the energy storage module, power conversion module, energy management module, etc. of the wave energy power generation equipment are all located inside the buoy, workers need to enter the buoy for installation and debugging. However, when the wave energy power generation equipment is working normally and testing experiments in the factory, for the sake of workers' safety, the 26m high wave energy power generation equipment needs to be laid flat. In this state, it is inconvenient for workers to enter, which increases the trouble of further tooling and debugging. The flat wave energy power generation equipment also puts higher requirements on the assembly of the hydraulic cylinder. After the tooling is completed, the device needs to simulate the ups and downs of the waves during work to collect data. At this time, the wave energy power generation equipment needs to be converted from the flat state back to the vertical state, and then simulate the energy generated by the ups and downs of the waves to facilitate subsequent testing and data collection.
[0006] The above tooling and testing process requires the wave energy power generation device to be switched between horizontal and vertical states multiple times in the factory. The wave energy power generation device weighs more than 100 tons. It is very complicated and dangerous to perform the switching operation using only equipment such as a crane. According to the particularity of the tooling and testing of the wave energy power generation device, it is urgent to use a special and effective tooling and testing system to solve the above problems.
[0007] After the tooling and testing are completed, placing a huge test system in the workshop is a waste of space resources. The occupation of space not only hinders the daily operation of the workshop, but also may become a bottleneck for the flow of vehicles and personnel, resulting in a significant reduction in traffic efficiency, complicated material handling, and affected employee work efficiency. This has led to the obstruction of the flow of materials and personnel in the workshop and increased the complexity of production operations. Therefore, solving the problem of the test system occupying workshop space is not only a rational use of space resources, but also an investment in improving production efficiency and maintaining corporate competitiveness. Summary of the invention
[0008] The present invention provides a tooling and testing system for oscillating float type wave energy power generation equipment, which can realize flexible and stable flipping and flat placement of the oscillating float type wave energy power generation equipment, facilitate operators to enter the buoy to perform tooling operations, adapt to different testing and experimental requirements, improve the stability of the test system, reduce dependence on external facilities, reduce testing costs, reduce floor space, facilitate storage, and solve the problems existing in the prior art.
[0009] In order to achieve the above object, one of the technical solutions adopted by the present invention is:
[0010] A tool for an oscillating buoy wave energy power generation device, comprising:
[0011] A lifting platform, wherein a load-bearing hydraulic system is arranged inside the lifting platform, and a rotating mechanical arm is supported and arranged above the lifting platform;
[0012] The first bracket is used to support and fix the traction mechanism; the traction mechanism cooperates with the rotating mechanical arm to realize the flipping conversion of the oscillating float type wave energy power generation equipment placed on the lifting platform between the vertical and horizontal states;
[0013] The second bracket is a horizontal bracket, which is used to support the upper part of the oscillating float type wave energy power generation equipment after it is laid flat. The horizontal bracket, the rotating mechanical arm and the traction mechanism cooperate to ensure the stable support of the oscillating float type wave energy power generation equipment after it is laid flat;
[0014] A catwalk is connected between the top ends of the first and second brackets, and a straight ladder is arranged outside the first bracket;
[0015] A base platform, the lifting platform is arranged in the middle of the base platform, and the first and second brackets are arranged relatively on the base platforms on both sides of the lifting platform; a test structure is also arranged on the base platform between the lifting platform and the second bracket, and the test structure realizes the test of the working condition by pulling up and down the oscillating float type wave energy power generation equipment placed in a vertical state to simulate the floating environment of ocean waves.
[0016] Furthermore, two supporting uprights are arranged opposite to each other on the outer side of the lifting platform, and a rotating mechanical arm is fixed on the inner side of each supporting upright; the height of the two rotating mechanical arms is lower than the bottom end of the buoy of the oscillating float type wave energy power generation equipment when the oscillating float type wave energy power generation equipment is vertically placed on the lifting platform; a concave through groove is arranged in the middle of the top end of the horizontal bracket, and the concave through groove is matched with the upper part of the oscillating float type wave energy power generation equipment. The concave through groove, the rotating mechanical arm and the traction mechanism cooperate to realize the stable support of the oscillating float type wave energy power generation equipment after it is laid flat.
[0017] Furthermore, the height of the rotating mechanical arm is below the buoy of the vertically placed oscillating float type wave energy power generation equipment. This position, as the gravity center of the oscillating float type wave energy power generation equipment after being laid flat, can provide more stable support.
[0018] Furthermore, a telescopic hydraulic cylinder is arranged between the rotating mechanical arm and the supporting vertical plate, and the telescopic hydraulic cylinder drives the two rotating mechanical arms to cooperate in clamping or loosening the lower part of the buoy of the oscillating float type wave energy power generation equipment.
[0019] Furthermore, the rotating mechanical arm includes a rotating mechanical arm bracket and a mechanical claw, the outer end of the rotating mechanical arm bracket is connected to the outer end of the piston rod of the telescopic hydraulic cylinder, and the cylinder body of the telescopic hydraulic cylinder is fixed on the supporting vertical plate via a rotating bearing.
[0020] Furthermore, the traction mechanism includes a hydraulic motor, an accumulator hydraulic station, a cable and a cable wheel; the hydraulic motor drives the cable wheel to retract and release the cable, one end of the cable is fixed on the cable wheel, and the other end is connected to the base of the oscillating float type wave energy power generation equipment; the accumulator hydraulic station includes a bladder accumulator, an oil tank and an oil pump motor; the bladder accumulator is arranged in the hydraulic circuit between the oil tank and the hydraulic motor to provide auxiliary power for the hydraulic motor.
[0021] Furthermore, as one of the commonly used accumulators, a one-way valve is provided between the bladder accumulator and the oil pump motor to prevent the pressure oil stored in the bladder accumulator from flowing back when the oil pump motor stops. The inflation port of the bladder accumulator is connected to one end of the external inflation tool, and the other end of the inflation tool is connected to the outlet of the nitrogen bottle through the inflation pipeline joint. The hydraulic oil outlet of the bladder accumulator is connected to the hydraulic oil outlet pipe and the return pipe, and stop valves are provided on the hydraulic oil outlet pipe and the return pipe; the hydraulic oil outlet pipe is connected to the pressure oil pipe of the hydraulic pipeline system to supply energy to the hydraulic motor. Before the pulling work, the hydraulic oil pumped by the oil pump motor enters the bladder accumulator through the one-way valve, and the air bag in the bladder accumulator is compressed and stored as the hydraulic oil is gradually filled. During the pulling process, when a greater pulling force is required, the hydraulic oil enters the pressure oil pipe through the hydraulic oil outlet pipe of the bladder accumulator to provide auxiliary power for the hydraulic motor.
[0022] Furthermore, when the hydraulic motor drives the cable to drag, the bladder accumulator acts as an auxiliary power source, releasing energy and feeding back the stored mechanical energy to the equipment. When the crane is lowered, the lowered energy can be stored in the bladder accumulator, thus making the lifting and stretching process smoother.
[0023] Further, the other end of the cable is hooked on the bottom support seat of the oscillating float type wave energy power generation equipment through a heavy-duty clevis safety hook. Before starting the hydraulic motor, ensure that the safety hook is correctly connected to the oscillating float type wave energy power generation equipment.
[0024] Furthermore, the load-bearing hydraulic system installed in the lifting platform can load up to 150 tons. The load-bearing hydraulic system can descend when the cable is retracted, which is convenient for the rotation of the oscillating float wave energy power generation equipment, avoiding obstructions below, and ensuring smooth flipping.
[0025] Furthermore, the cables in the above-mentioned traction mechanism are high-load cables, which ensure that the oscillating buoy wave energy power generation equipment can complete precise leveling and vertical operations when flipping.
[0026] Furthermore, the test structure includes a retractable bracket, a fixed pulley group, and a rope; the fixed pulley group is respectively arranged at the top and bottom of the retractable bracket; one end of the rope wound around the fixed pulley group is connected to the buoy of the oscillating float type wave energy power generation equipment, and the other end of the rope is connected to an external crane.
[0027] Furthermore, by setting up a fixed pulley group, the fixed pulley at the bottom of the retractable bracket cooperates with the fixed pulley at the top thereof, thereby achieving the purpose of transferring the hanging point position from the top to the bottom of the oscillating float wave energy power generation equipment, leaving a larger rising and falling space.
[0028] Furthermore, one end of the rope is connected to the eye on the buoy through a hook, and the other end is provided with an eye for connecting the hook of the crane. When the crane is towed upward, the buoy is raised or lowered through the fixed pulley block, which not only increases the lifting stroke, but also provides a certain degree of protection for the crane motor.
[0029] Furthermore, if the driving power is relatively small, a labor-saving movable pulley block can be used in combination with the fixed pulley block to further reduce the driving burden and prevent the motor from being burned.
[0030] Furthermore, each telescopic section of the retractable bracket is provided with a latch as a mechanical protection, and the bracket can be extended and retracted by removing the latch, so that the device can be stored conveniently when the factory is idle, thus saving workshop space and avoiding collision accidents between the vehicle and the bracket.
[0031] Furthermore, the bottom of the retractable bracket is fixed to one end of two supporting vertical plates arranged on the outside of the lifting platform and used to support the rotating mechanical arm.
[0032] Furthermore, the bottom of the retractable bracket is fixed to one end of the two supporting vertical plates close to the second bracket.
[0033] Furthermore, a track wheel is arranged at the bottom end of the base platform, and the base platform is detachably assembled and connected via a plurality of comb-tooth-shaped plug-ins. The protruding part of the comb-tooth-shaped plug-ins avoids the load-bearing beam of the base platform and can be more retracted to save space.
[0034] Furthermore, different comb-tooth-shaped plugboards on the base platform correspond to supporting structures at different positions thereon. For example, the comb-tooth-shaped plugboards for assembling the base platform can be set to 4 groups, namely, the base plugboards for supporting the first and second brackets, the base plugboards for the lifting platform, and the remaining base platform boards without support. The comb-tooth-shaped plugboards that make up the base platform, the entire tooling can be divided into four parts for easy subsequent storage.
[0035] Furthermore, the catwalk is also a retractable catwalk. After removing the bolts fixing the base platform and the retractable fuse of the catwalk, the bottom track wheel is driven to store the entire device to the maximum extent.
[0036] The second technical solution adopted by the present invention is:
[0037] A test system for oscillating buoy wave energy power generation equipment includes the above-mentioned tooling, and a driving lifting point is provided on the base platform between the lifting platform and the second bracket; the test operation steps of the test system are as follows:
[0038] S1 accurately places the oscillating buoy wave energy power generation equipment on the lifting platform through the crane. At this time, the rotating mechanical arm is correspondingly located below the buoy of the oscillating buoy wave energy power generation equipment.
[0039] S2 connects the outer end of the cable of the traction mechanism to the base of the oscillating float type wave energy power generation equipment, and drives the rotating mechanical arm to horizontally approach and hold the oscillating float type wave energy power generation equipment tightly;
[0040] S3 starts the traction mechanism to pull the bottom of the oscillating float type wave energy power generation equipment upward. At the same time, the lifting platform descends and the rotating mechanical arm rotates, so as to coordinate and complete the gradual clockwise flipping of the oscillating float type wave energy power generation equipment from a vertical state until the upper part of the oscillating float type wave energy power generation equipment contacts and supports the horizontal support; the operator enters the buoy of the oscillating float type wave energy power generation equipment through the vertical ladder and catwalk to install and debug;
[0041] After the installation and commissioning of S4 is completed, the traction mechanism and the rotating mechanical arm are used again to gradually lower the installed oscillating float wave energy power generation equipment from the horizontal position counterclockwise and turn it to the initial vertical position, standing on the lifting platform;
[0042] S5 disconnects the connection between the traction mechanism and the base of the oscillating buoy type wave energy power generation equipment, and drives the rotating mechanical arm to release the oscillating buoy type wave energy power generation equipment;
[0043] S6 connects the test structure through the lifting lugs on the buoy of the oscillating float wave energy power generation equipment to conduct operating tests in a simulated ocean wave floating environment.
[0044] Furthermore, in step S6, the retractable support of the test structure is adjusted to a suitable height and fixed, one end of the rope wound around the fixed pulley block on the retractable support is connected to the lifting lug on the buoy of the oscillating float wave energy power generation equipment, and the other end of the rope is connected to the hook of the external driving; when the driving is towed upward, the buoy is raised or lowered through the fixed pulley block, thereby increasing the lifting stroke. This facilitates the working condition test in a floating environment.
[0045] Beneficial effects of the present invention:
[0046] The tooling and test system for oscillating float wave energy power generation equipment of the present invention optimizes the performance and function of the test equipment from multiple aspects such as convenient, safe and effective tooling, convenient storage, and space saving, thus bringing remarkable beneficial effects.
[0047] The tooling and test system of the present invention are designed with a function that can rotate the oscillating float wave energy power generation equipment, so that the equipment can be converted between horizontal and vertical positions. This innovative design increases the flexibility and adaptability of the test system, and can better adapt to different test and experimental requirements. The tooling and test system are added with an accumulator hydraulic station to provide auxiliary power for the tooling pulling process and ensure stability during the pulling process; the setting of the fixed pulley group can effectively reduce the instantaneous power requirement during the test process, thereby balancing the energy supply demand, improving the stability of the test system, reducing dependence on external energy, and reducing the test cost. The base platform adopts a retractable design, and after the test is completed, it can be retracted to a smaller space to save space resources and improve the utilization rate of the plant. This is particularly important for laboratories and work areas with limited space, and effectively improves the space utilization rate and storage efficiency of the equipment. Through the installation of the track wheel composed of pulleys and tracks, the tooling of the present invention can be easily moved to the designated storage location when needed, ensuring that it does not affect the normal passage and space use of the workshop, and is more flexible.

DETAILED DESCRIPTION
[0059] In order to clearly illustrate the technical features of this solution, the present invention is described in detail below through specific implementation methods in conjunction with the accompanying drawings.
[0060] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.
[0061] like Figure 1-Figure 6, shows the tooling structure for the oscillating float wave energy power generation equipment (hereinafter referred to as wave energy power generation equipment), which is mainly composed of a lifting platform 1, a base platform 2, a straight ladder 3, a hydraulic motor 4, a cable 5, a catwalk 6, a rotating mechanical arm 7, a fixed pulley group 8, a retractable bracket 9, a horizontal bracket 10, etc. The cable 5 is arranged on the cable wheel, and the hydraulic motor 4 is connected to the accumulator hydraulic station. The accumulator hydraulic station includes an oil pump motor 15, a bladder accumulator 16 and an oil tank 20. The hydraulic motor, the cable, and the accumulator hydraulic station together constitute the traction mechanism of the tooling. A load-bearing hydraulic system is arranged in the lifting platform 1, which can reach a maximum load of 150T, and the rotating mechanical arm 7 is supported and arranged above the lifting platform.
[0062] Specifically, two supporting uprights 101 are arranged opposite to each other on the outside of the lifting platform 1, and the aforementioned rotating mechanical arm 7 is fixed on the inside of each supporting upright; when the wave energy power generation equipment is vertically placed on the lifting platform 1, the height of the two rotating mechanical arms is lower than the bottom end of the buoy 21 of the wave energy power generation equipment. A concave through groove 100 is arranged in the middle of the top of the horizontal support 10, and the concave through groove matches the upper part of the wave energy power generation equipment. The concave through groove, the rotating mechanical arm and the traction mechanism cooperate to achieve a stable support for the wave energy power generation equipment after it is laid flat. The height of the rotating mechanical arm is below the buoy of the vertically placed wave energy power generation equipment. This position, as the center of gravity of the wave energy power generation equipment after it is laid flat, can provide a more stable support. A telescopic hydraulic cylinder 13 is arranged between the rotating mechanical arm and the supporting upright, and the telescopic hydraulic cylinder drives the two rotating mechanical arms 7 to cooperate in holding or loosening the lower part of the buoy of the wave energy power generation equipment.
[0063] The rotating mechanical arm 7 comprises a rotating mechanical arm bracket 701 and a mechanical claw 702 . The outer end of the rotating mechanical arm bracket is connected to the outer end of the piston rod of the telescopic hydraulic cylinder 13 . The cylinder body of the telescopic hydraulic cylinder is supported and fixed on the supporting vertical plate 101 via a rotating bearing 12 .
[0064] In the above traction mechanism, one end of the cable 5 is connected to the cable wheel, and the other end of the cable is hooked on the bottom support seat 24 of the wave energy power generation equipment through a heavy-duty clevis safety hook. Before starting the hydraulic motor 4, ensure that the safety hook is correctly connected to the oscillating float wave energy power generation equipment. The traction mechanism is the main power source for pulling the wave energy power generation equipment to flip. The cable is a high-load cable, which ensures that the wave energy power generation equipment can complete accurate flat and vertical operations when flipping.
[0065] The fixed pulley block 8, the retractable bracket 9, the rope and the external crane 22 arranged on the aforementioned base platform 2 constitute the test structure of the tooling. The test structure tests the working condition by pulling up and down the vertically placed wave energy power generation equipment to simulate the floating environment of ocean waves. The fixed pulley block 8 is respectively arranged at the top and bottom of the retractable bracket; one end of the rope 14 wound around the fixed pulley block is connected to the buoy 21 of the wave energy power generation equipment, and the other end of the rope is connected to the external crane 22.
[0066] By setting a fixed pulley group, the fixed pulley at the bottom of the retractable bracket cooperates with the fixed pulley at the top thereof, so as to achieve the purpose of transferring the suspension point position from the top to the bottom of the wave energy power generation equipment, leaving a larger space for rising and falling. Each telescopic section of the retractable bracket 9 is provided with a latch as a mechanical protection. The latch can be removed to extend and retract, which is convenient for storing the device when the factory is idle, saving workshop space and avoiding collision accidents between the vehicle and the bracket. The bottom of the retractable bracket is fixed to the right side of the two supporting vertical plates 101.
[0067] One end of the rope is connected to the eye on the buoy through a hook, and the other end is provided with an eye for connecting the hook of the crane. When the crane is towed upward, the buoy is raised or lowered through the fixed pulley block, which not only increases the lifting stroke, but also provides a certain degree of protection for the crane motor. Fig. 9 If the driving power is small, a labor-saving movable pulley block 23 can be used in combination with the fixed pulley block to further reduce the driving burden and avoid the motor from being burned. See the schematic diagram for details. Fig.10 .
[0068] A track wheel 18 is arranged at the bottom end of the base platform 2, and the base platform is detachably assembled and connected via a plurality of comb-tooth-shaped plug-ins 19. The protruding part of the comb-tooth-shaped plug-ins avoids the load-bearing beam of the base platform and can be more retracted and space-saving.
[0069] The base platform 2 is specifically configured as an upper base and a lower base in two layers, a supporting circular tube 11 is provided between the upper and lower bases, and the track wheels are provided on the lower base. The multiple comb-tooth-shaped plug-ins constituting the base platform correspond to supporting structures at different positions thereon, respectively. For example, the comb-tooth-shaped plug-ins of the assembled base platform can be configured as 4 groups, namely, the base plug-ins for supporting the traction mechanism, the base plug-ins for the horizontal bracket, the base plug-ins for supporting the lifting platform, and the other base platform plates without support. This structural form is convenient for storage after disassembly.
[0070] See also Figure 7-10 , which is a reference schematic diagram of the working state of the tooling test system for wave energy power generation equipment. Combined with the tooling structure, the operating system and the working steps of the test operation are introduced.
[0071] The test system includes the aforementioned tooling structure, and a crane lifting point 17 is provided on the base platform between the lifting platform and the horizontal bracket. The test operation steps of the test system are as follows:
[0072] S1. The wave energy power generation equipment is accurately placed on the lifting platform 1 by means of a crane. At this time, the rotating mechanical arm 7 is correspondingly located below the buoy 21 of the wave energy power generation equipment;
[0073] S2, connecting the outer end of the cable 5 of the traction mechanism to the base of the wave energy power generation equipment, and driving the rotating mechanical arm 7 to make it horizontally approach and hold the wave energy power generation equipment tightly;
[0074] S3, start the traction mechanism to pull the bottom of the wave energy power generation equipment upward, and at the same time, the lifting platform descends and the rotating mechanical arm rotates, so as to complete the gradual clockwise flipping of the wave energy power generation equipment from a vertical state, until the upper part of the wave energy power generation equipment contacts and supports the horizontal support; the operator enters the buoy of the wave energy power generation equipment through the vertical ladder 3 and the catwalk 6 to install and debug;
[0075] S4. After the installation and debugging is completed, the traction mechanism and the rotating mechanical arm cooperate again to gradually rotate the installed wave energy power generation equipment from the horizontal to the initial vertical state counterclockwise and stand on the lifting platform 1;
[0076] S5, disconnecting the traction mechanism from the base of the wave energy power generation equipment, and driving the rotating mechanical arm to release the wave energy power generation equipment;
[0077] S6. Connect the test structure through the lifting lug on the buoy 21 of the wave energy power generation equipment. Specifically, adjust the retractable bracket 9 of the test structure to a suitable height and fix it, connect one end of the rope 14 wound around the fixed pulley block 8 on the retractable bracket to the lifting lug on the buoy of the wave energy power generation equipment, and connect the other end of the rope to the hook of the external crane. When the crane is towed upward, the buoy is raised or lowered through the fixed pulley block, thereby increasing the lifting stroke, simulating the floating environment of ocean waves, and conducting working condition tests on power generation efficiency, power generation, etc.
[0078] The traction mechanism in the above steps S3 and S4 is a structure as described in the aforementioned tooling. Since an accumulator hydraulic station is provided, the bladder accumulator 16 therein can store energy and release energy when needed, providing auxiliary power for the hydraulic motor 4, thereby ensuring the stability and sufficiency of power during the pulling and lowering of the towing cable.
