Abstract

The application discloses a detection device of a wave energy device and belongs to the technical field of marine device detection devices. The device comprises a horizontal cross beam, an arc-shaped guide rail and a suspension mechanism. The horizontal cross beam and the arc-shaped guide rail form an arc-shaped structure. The suspension mechanism is slidably connected with the arc-shaped guide rail. One end of the horizontal cross beam is provided with a first lifting ring, and the other end of the horizontal cross beam is provided with at least three second lifting rings along the length direction of the horizontal cross beam. When lifting, the lifting speed of the two ends of the horizontal cross beam is changed to generate a speed difference in the vertical direction, then the horizontal movement is generated through the transverse sliding of the suspension mechanism, and the random motion track is generated through the mutual composition of multiple movements, so that the motion state of the sea wave can be more truly simulated. The application effectively solves the problems that the existing detection device has a single fitted motion track and cannot restore the actual working environment, so that the detected data is distorted and has low reference value.

Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of ocean device detection equipment, and particularly relates to a detection equipment for wave energy devices. BACKGROUND

[0002] With the increasing energy consumption, countries are in urgent need of a renewable clean energy to alleviate the impact of energy shortage.

[0003] The ocean, as the most widely distributed natural resource on earth, has a huge amount of energy hidden inside, which is immeasurable. With the in-depth study of ocean resources, after the tidal energy, another ocean energy-wave energy is converted by scientists to be used in various production and living activities. In order to ensure that the wave energy collection device can work stably under different wind and wave conditions, the performance detection needs to be carried out before use. The traditional detection work needs to ship the wave energy collection device to the real marine environment for detection, but due to the frequent changes of the wind and wave conditions of the natural environment, in order to test the running condition of the wave energy collection device under different wind and wave conditions, the time and place need to be coordinated, that is, the appropriate test data can be obtained only in the specific test area and the corresponding sea conditions. This test method not only seriously affects the detection efficiency, but also needs a large amount of test funds, thereby indirectly increasing the production cost.

[0004] In order to solve the above problems, the Chinese invention with the publication number CN107101802B discloses a wave energy power generation waterless experiment bench, which is mainly used for simulating the dynamic stress condition of the wave energy power generation device in the wave and testing the power generation capacity. The wave energy power generation device is subjected to the wave action force, the seawater buoyancy and the seawater damping of the ocean, and the mechanical and electrical parameters are automatically collected under the computer control, the experiment process is automatically carried out, and various technical parameters can be flexibly adjusted.

[0005] However, it is found in the actual use that the experiment bench still has some deficiencies:

[0006] 1) The power source for lifting the wave energy power generation device of the experiment bench is single, and only one servo motor is used to realize the periodic reciprocating motion of the wave energy power generation device, so that the motion change rule of the wave energy power generation device is simple, and the motion state of the sea wave cannot be truly simulated.

[0007] 2) The experiment bench adopts the mode of rotating wheel driving rope to drive the wave energy power generation device to move up and down reciprocatingly. With the passage of time and the increase of transmission times, the slippage between the rotating wheel and the rope will gradually increase, which seriously affects the actual motion condition of the wave energy power generation device, and the working state in the seawater cannot be truly simulated, and the authenticity of the test data cannot be guaranteed.

[0008] Therefore, it is necessary to design a detection device capable of effectively simulating the motion state of sea waves. SUMMARY

[0009] In order to overcome the defects of the prior art, the technical problem to be solved by the present application is how to provide a detection device capable of effectively simulating the motion state of sea waves.

[0010] In order to solve the above technical problems, the technical scheme adopted by the present application is as follows: a detection device of a wave energy device, comprising a horizontal cross beam, an arc-shaped guide rail and a suspension mechanism; the arc-shaped guide rail is arranged below the horizontal cross beam and forms an arc structure with the horizontal cross beam; the suspension mechanism and the arc-shaped guide rail are slidingly connected; one end of the horizontal cross beam is provided with a first lifting ring, and the other end is provided with at least three second lifting rings along the length direction of the horizontal cross beam.

[0011] The detection device of the wave energy device provided by the present application has the advantages of simple structure and convenient use. By arranging any hoisting device at the first lifting ring and the second lifting ring and changing the running speed of the hoisting device according to the detection requirements, the speed difference between the two ends of the horizontal cross beam is generated in the lifting process. Since the suspension mechanism and the arc-shaped guide rail are slidingly connected, the random motion trajectory can be generated under the combined action of multiple motions, so that the motion state of sea waves can be more realistically simulated.

[0019] In order to explain the technical content, the purposes and effects of the present application in detail, the following will be described in combination with the embodiments and the accompanying drawings.

[0020] ​The most critical concept of the present application is that: when lifting, the horizontal beam generates a speed difference by changing the lifting of the two ends of the horizontal beam, and the horizontal beam is transversely slid by the suspension mechanism, so that multiple movements are combined with each other, that is, a random motion trajectory is generated, so that the motion state of the sea wave can be more realistically simulated.

[0021] Please refer to Figures 1 to 3 The detection equipment of the wave energy device provided by the present application comprises a horizontal beam 1, an arc-shaped guide rail 2 and a suspension mechanism 3; the arc-shaped guide rail 2 is arranged below the horizontal beam 1 and forms an arc structure with the horizontal beam 1; the suspension mechanism 3 and the arc-shaped guide rail 2 are slidably connected; one end of the horizontal beam 1 is provided with a first lifting ring 11, and the other end is provided with at least three second lifting rings 12 along the length direction of the horizontal beam 1.

[0022] As can be known from the above description, the detection equipment of the wave energy device provided by the present application has the beneficial effects that: when lifting, the horizontal beam 1 generates a speed difference in the vertical direction by changing the lifting speed of the two ends of the horizontal beam 1, and then generates a horizontal movement by the transverse sliding of the suspension mechanism 3, so that multiple movements are combined with each other, that is, a random motion trajectory is generated, so that the motion state of the sea wave can be more realistically simulated; the device has a simple structure and is easy to operate, and compared with the existing detection equipment, the motion trajectory fitted by the device is more diversified, so that the actual working environment is restored as much as possible, and the data obtained by detection is more real and has more reference value.

[0023] Further, the length of the horizontal beam 1 is 2m-10m. Preferably, the length of the horizontal beam 1 is 5m-10m, and more preferably, the length of the horizontal beam 1 is 10m.

[0024] Further, the arc structure formed by the horizontal beam 1 and the arc-shaped guide rail 2 is an axisymmetric structure, and the distance between the midpoint of the horizontal beam 1 and the midpoint of the arc-shaped guide rail 2 is 1 / 8-1 / 2 of the length of the horizontal beam 1. Preferably, the distance between the midpoint of the horizontal beam 1 and the midpoint of the arc-shaped guide rail 2 is 1 / 4 of the length of the horizontal beam 1.

[0025] Further, the arc-shaped guide rail 2 is a parabolic type.

[0026] As can be known from the above description, the arc structure formed by the horizontal beam 1 and the arc-shaped guide rail 2 is an axisymmetric structure, which can ensure that the motion state is consistent when the suspension mechanism 3 slides from the lowest part of the arc-shaped guide rail 2 to any end of the arc-shaped guide rail 2; and the arc-shaped guide rail 2 is a parabolic type, which can further ensure the smoothness of the sliding of the suspension mechanism 3 and avoid interference factors affecting the overall detection work. The horizontal beam should not be too long or too short, otherwise the overall anti-deformation strength or the detection data of the to-be-detected device will be affected.

[0027] Further, the distance between the second lifting rings 12 is 1 / 20-1 / 10 of the length of the horizontal beam 1.

[0028] From the above description, it can be known that by changing the suspension position of the lifting device and the second lifting ring 12, the movement speed of the suspension mechanism 3 in the vertical direction can be effectively changed; the closer the suspension position is to the midpoint of the horizontal beam 1, the faster the movement speed of the suspension mechanism 3 in the vertical direction when lifting.

[0029] Further, the suspension mechanism 3 comprises a pulley 31, a connecting frame 32 and a lifting hook 33; one end of the connecting frame 32 is connected with the pulley 31, and the other end is connected with the lifting hook 33; the connecting frame 32 is sleeved with the arc-shaped guide rail 2; the pulley 31 is slidingly connected with the arc-shaped guide rail 2, and the pulley 31 is arranged towards the horizontal beam 1, that is, the pulley is located between the horizontal beam and the arc-shaped guide rail, rather than below the arc-shaped guide rail.

[0030] From the above description, it can be known that the design can provide basic guarantee for the suspension mechanism 3 to drive the related to-be-detected device to reciprocate on the arc-shaped guide rail 2.

[0031] Further, the contact position between the pulley 31 and the arc-shaped guide rail 2 is provided with a rubber layer.

[0032] From the above description, it can be known that the design can not only avoid the slipping between the pulley 31 and the arc-shaped guide rail 2, but also can protect the pulley 31 and the arc-shaped guide rail 2, so as to prevent the service life of the detection equipment from being shortened due to excessive wear between the pulley 31 and the arc-shaped guide rail 2.

[0033] Further, the load range of the lifting hook 33 is 5t-10t.

[0034] From the above description, it can be known that the lifting hook 33 with the load strength can meet the detection work of the conventional wave energy collection device.

[0035] Further, the material of the horizontal beam 1 and the arc-shaped guide rail 2 is steel.

[0036] From the above description, it can be known that, compared with other materials, the selection of the steel material can effectively improve the overall strength of the equipment.

[0037] Further, the horizontal beam 1 and the arc-shaped guide rail 2 are integrally formed.

[0038] From the above description, it can be known that the design can further improve the anti-deformation strength of the detection equipment, and can effectively avoid the fracture at the connection between the horizontal beam 1 and the arc-shaped guide rail 2.

[0039] The detection equipment of the wave energy device can assist the detection work of the wave energy collection device.

[0040] An embodiment of the present application is:

[0041] With reference to Figures 1 to 3 A detection device of a wave energy device, comprising a horizontal beam 1, an arc-shaped guide rail 2 and a suspension mechanism 3; the arc-shaped guide rail 2 is arranged below the horizontal beam 1 and forms an arc structure with the horizontal beam 1; the suspension mechanism 3 and the arc-shaped guide rail 2 are in sliding connection; one end of the horizontal beam 1 is provided with a first lifting ring 11, and the other end is provided with three second lifting rings 12 along the length direction of the horizontal beam 1; the length of the horizontal beam 1 is 10 m; the arc structure formed by the horizontal beam 1 and the arc-shaped guide rail 2 is an axisymmetric structure; the distance between the midpoint of the horizontal beam 1 and the midpoint of the arc-shaped guide rail 2 is 1 / 4 of the length of the horizontal beam 1; the arc-shaped guide rail 2 is in a parabolic shape; the distance between the second lifting rings 12 is 1 / 20 of the length of the horizontal beam 1; the suspension mechanism 3 comprises a pulley 31, a connecting frame 32 and a lifting hook 33; one end of the connecting frame 32 is connected with the pulley 31, and the other end is connected with the lifting hook 33; the connecting frame 32 is sleeved with the arc-shaped guide rail 2; the pulley 31 is in sliding connection with the arc-shaped guide rail 2, and the pulley 31 is arranged towards the horizontal beam 1 (i.e. the pulley 31 is located between the horizontal beam 1 and the arc-shaped guide rail 2, rather than below the arc-shaped guide rail 2); a rubber layer is arranged at the contact position of the pulley 31 and the arc-shaped guide rail 2; the horizontal beam 1 and the arc-shaped guide rail 2 are made of steel; and the horizontal beam 1 and the arc-shaped guide rail 2 are in an integral forming structure.

[0042] The working principle of the present application is as follows: firstly, any hoisting device is arranged at the first lifting ring 11 and the second lifting ring 12 respectively, so that the horizontal beam 1, the arc-shaped guide rail 2 and the suspension mechanism 3 are in a hovering state; then the related equipment to be detected is fixed on the lifting hook 33 of the suspension mechanism 3; then the hoisting device is started to make the horizontal beam 1 perform lifting action, and the two ends of the horizontal beam 1 are ensured to generate a speed difference in the vertical direction; at this time, due to the existence of the speed difference, the suspension mechanism 3 will deviate to the end with slow moving speed of the horizontal beam 1 in the process of driving the related equipment to be detected to rise, and will deviate to the end with fast moving speed of the horizontal beam 1 in the process of driving the related equipment to be detected to descend; through the compound motion, the state of sea wave motion can be truly restored.

[0043] Since the fluctuation state of sea wave is unstable, in order to better simulate various states of sea wave and obtain real and reliable detection parameters, only the suspension position between the hoisting device and the second lifting ring 12 needs to be changed to change the motion amplitude of the horizontal beam 1, the arc-shaped guide rail 2 and the suspension mechanism 3; the closer the suspension position between the hoisting device and the second lifting ring 12 is to the central position of the horizontal beam 1, the faster the moving speed of the suspension mechanism 3 in the vertical direction is when lifting. Thus the overall flexibility of the detection device is improved.

[0044] In summary, the wave energy device detection equipment provided by the application has the advantages of simple structure and convenient operation; when lifting, the lifting speed of the two ends of the horizontal beam is changed to generate a speed difference in the vertical direction of the horizontal beam, and then the horizontal movement is generated through the lateral sliding of the suspension mechanism, so that multiple movements are compounded, that is, a random motion trajectory is generated, so that the motion state of the sea wave can be more truly simulated; and the shortcomings of the existing detection equipment, that is, the fitted motion trajectory is single and cannot restore the actual working environment, so that the detected data is distorted and has low reference value, are overcome.

[0045] The above description is only an embodiment of the application, and does not limit the patent range of the application, and any equivalent transformation or direct or indirect application in the related technical field by using the content of the specification and drawings of the application is also included in the patent protection range of the application.
