Description

[0002] The wind-powered propulsion rotor is a tall, large cylindrical structure. After being installed on a ship, it needs to be switched between horizontal and vertical positions as needed during cargo loading and unloading or when encountering a low bridge.

[0003] After the hydraulic tilting device for the wind-powered rotor is manufactured, it needs to undergo thorough testing to ensure the system's safety. Directly using the wind-powered rotor under test for hydraulic tilting testing means the weight and center of gravity of the fixture cannot be adjusted. If the hydraulic tilting device fails during testing, the load limit of the hydraulic tilting device for the weight and center of gravity of the wind-powered rotor cannot be determined. Utility Model Content

[0004] The purpose of this invention is to provide a test fixture for a hydraulic tilting device for a wind-powered rotor. This test fixture can perform graded loading tests on the hydraulic tilting device in order to determine the load limits of the wind-powered rotor's weight and center of gravity height.

[0005] To achieve this objective, the present invention adopts the following technical solution:

When i is a positive integer greater than 1 and less than or equal to N, the i cylinders are cylinder 1, ..., cylinder i, which are sequentially coaxially connected to form the main simulation part. The lifting mechanism is connected to one end of the cylinder of the main simulation part.

[0007] Preferably, along the direction of sequential connection of the cylinders of the main simulation part, the connecting parts at both ends of each cylinder are the upper flange and the lower flange, respectively; the test fixture for the wind-powered rotor hydraulic tilting device also includes multiple bolts and multiple nuts.

[0008] Preferably, the cylinder includes an outer shell, a support plate, and a fixed counterweight. The support plate is disposed inside the outer shell, and a limiting space is formed between the support plate and the upper flange. The fixed counterweight is disposed within the limiting space.

[0009] Preferably, the cylinder further includes a plurality of reinforcing ribs, which are spaced apart on the outer periphery of the outer shell and extend along the axial direction of the outer shell.

Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0027] This embodiment provides a test fixture for a hydraulic tilting device for a wind-powered rotor, which is used to replace the wind-powered rotor to be tested for tilting tests.

[0028] Please refer to Figures 1 to 4 The test fixture for the wind-powered rotor hydraulic tilting device includes a lifting mechanism 2 and N cylinders 11. The lifting mechanism 2 is used to connect to the lifting equipment and can be connected to any cylinder 11. N is an integer not less than 2. Each cylinder 11 has a connecting part 111 at both ends, and the connecting parts 111 of any two cylinders 11 can be detachably connected. The N cylinders 11 are respectively the first cylinder, the second cylinder, ... the Nth cylinder. The system can combine N types of simulated rotors. The i-th type of simulated rotor is composed of a lifting mechanism 2 and i cylinders 11. When i equals 1, the cylinder is the first cylinder, and the lifting mechanism 2 is connected to one end of the first cylinder. When i is a positive integer greater than 1 and less than or equal to N, the i cylinders 11 are the first cylinder, ..., the i-th cylinder, and so on, coaxially connected to form the main simulated part 1. The lifting mechanism 2 is connected to one end of the cylinder 11 of the main simulated part 1. The weight and center of gravity of the N-th type of simulated rotor are the same as those of the wind-driven rotor to be tested. Among the other simulated rotors, from the (N-1)-th simulated rotor to the first simulated rotor, the weight and center of gravity of the simulated rotor decrease successively.

[0029] When testing the hydraulic tilting device, the tests are performed sequentially starting with the first type of simulated rotor. Specifically, when the i-th type of simulated rotor is tested, if the test is passed, the subsequent simulated rotors are tested, and so on, until the N-th type of simulated rotor is tested. If the N-th type of simulated rotor passes the test, it indicates that the hydraulic tilting test of the wind-powered rotor under test is successful. If the i-th type of simulated rotor fails the test, there is no need to tilt the subsequent simulated rotors, and it indicates that the tilting test of the wind-powered rotor under test is unsuccessful. Furthermore, the weight and center of gravity height of the wind-powered rotor under test should not exceed the weight and center of gravity height corresponding to the i-th type of simulated rotor. Therefore, this hydraulic tilting device testing fixture for wind-powered rotors can ensure the safety and reliability of the test when used for tilting device testing.

[0030] Specifically, please refer to Figures 1 to 3 Along the direction in which the cylinders 11 of the main simulation unit 1 are connected sequentially, the connecting parts 111 at both ends of each cylinder 11 are an upper flange 1111 and a lower flange 1112, respectively. The test fixture for the wind-powered rotor hydraulic tilting device also includes multiple bolts and multiple nuts. In any two interconnected cylinders 11, multiple bolts pass sequentially through the lower flange 1112 of one cylinder 11 and the upper flange 1111 of the other cylinder 11, and the multiple bolts and multiple nuts are threadedly connected one-to-one. With this configuration, the installation and disassembly of each cylinder 11 is simple. When conducting hydraulic tilting tests under different working conditions, corresponding simulated rotors can be combined according to requirements, shortening the test preparation time and improving test efficiency.

[0031] Preferably, multiple bolts are evenly spaced along the circumferential direction of the connecting part 111 to ensure that the two interconnected cylinders 11 are subjected to uniform force along the circumferential direction of the connecting part 111, thereby ensuring that the two interconnected cylinders 11 are directly connected in a stable and reliable manner.

[0032] Alternatively, please refer to Figure 2 The cylinder 11 includes an outer shell 112, a support plate 113, and a fixed counterweight 114. The support plate 113 is disposed within the outer shell 112, and a limiting space is formed between the support plate 113 and the upper flange 1111. The fixed counterweight 114 is disposed within the limiting space. This design of the limiting space effectively prevents the fixed counterweight 114 from shifting inside the cylinder 11. This avoids displacement of the counterweight during testing, especially when the simulated rotor is tilting, which could affect the accuracy and reliability of the test.

[0033] Furthermore, the limiting space for placing the fixed counterweight 114 is located at the top of the cylinder 11. Compared with other positions of the fixed counterweight 114 on the cylinder 11, this increases the height of the center of gravity of the cylinder 11, which is beneficial to reduce the size of the test fixture for the wind-powered rotor hydraulic tilting device and facilitates the actual operation of equipment assembly and testing.

[0034] Further, please refer to Figure 3 The test fixture for the wind-powered rotor hydraulic tilting device also includes several movable counterweights 115. In the i-th type of simulated rotor, the movable counterweights 115 are selectively loaded onto the top of the i-th cylinder 11. Specifically, the i-th type of simulated rotor has the weight and center of gravity height that simulate a real wind-powered rotor. With this configuration, after conducting a full-load test of the hydraulic tilting device using the i-th type of simulated rotor, the weight and center of gravity height of the simulated rotor can be adjusted by loading the movable counterweights 115 to test the load limit of the hydraulic tilting device.

[0035] Alternatively, please refer to Figure 1The center of gravity height of the first cylinder is L1, the center of gravity height of the Nth cylinder is L3, and the center of gravity height of the remaining cylinders 11 is L2, where L1 > L2 > L3. With this setup, during the hydraulic tilting device test, the first cylinder is used to form the first type of simulated rotor for the first hydraulic tilting device test. Then, the first cylinder and the second cylinder are connected to form the second type of simulated rotor for the second hydraulic tilting device test, and so on. The hydraulic tilting device is subjected to graded loading tests, with the center of gravity height of the first cylinder set to the maximum. This ensures that as the number of tests increases, the increase in the center of gravity height of the simulated rotor gradually decreases, further guaranteeing the safety of the test. Since the center of gravity heights of the second to the (N-1)th cylinders are the same, the change in center of gravity height from the second type of simulated rotor to the (N-1)th type of simulated rotor is the same. This facilitates the identification of the changing trends in the performance parameters of the hydraulic tilting device caused by each change in the center of gravity height under loading, and is convenient for theoretical analysis. The center of gravity height of the Nth cylinder is set to the minimum. At this time, the center of gravity height of the simulated rotor reaches the rated center of gravity height of the hydraulic tilting device, that is, it has the same center of gravity height as the wind-powered rotor under test, which is beneficial to evaluate the reliability of the hydraulic tilting device.

[0036] Optionally, the weight of the first cylinder is G1, the weight of the Nth cylinder is G3, and the weight of the remaining cylinders 11 is G2, where G1 > G2 > G3. A graded loading test is performed on the hydraulic tilting device. The weight of the first cylinder is set to the maximum, so that during the test, the weight increase of the simulated rotor gradually decreases with the increase in the number of tests, further ensuring the safety of the test. The weights of the second to N-1th cylinders are the same, so the weight change of the second to N-1th simulated rotors is the same, which is helpful in identifying the trend of performance parameter changes of the hydraulic tilting device caused by each load weight change, facilitating theoretical analysis. The weight of the Nth cylinder is set to the minimum, at which point the weight of the simulated rotor reaches the rated weight of the hydraulic tilting device, that is, it has the same weight as the wind-powered propulsion rotor under test, which is beneficial for evaluating the reliability of the hydraulic tilting device.

[0037] Preferably, please refer to Figure 1 and Figure 2 The cylinder 11 also includes multiple reinforcing ribs 116, which are spaced apart on the outer periphery of the outer shell 112 and extend along the axial direction of the outer shell 112. The reinforcing ribs 116 enhance the rigidity of the cylinder 11, thereby increasing its resistance to deformation. This prevents excessive deformation of the cylinder 11 during tilting, ensuring the shape and dimensional stability of the simulated rotor and making the test results more accurate and reliable.

[0038] Alternatively, please refer to Figure 1 and Figure 4The lifting mechanism 2 includes a connecting plate 21, a reinforcing member 22, and multiple lifting lugs 23. In the i-th type of simulated rotor, the connecting plate 21 is detachably connected to the connecting part 111 of the i-th cylinder. The reinforcing member 22 is disposed on the connecting plate 21, and the multiple lifting lugs 23 are disposed on the reinforcing member 22. The lifting lugs 23 are used to connect with the lifting equipment. Preferably, the lifting mechanism 2 also has an annular reinforcing plate to strengthen the strength of the connecting plate 21. The annular reinforcing plate and the reinforcing member 22 are disposed on the same side of the connecting plate 21. With this configuration, during loading operations, the connecting plate 21 is connected to the cylinder 11 to be loaded, and the lifting lugs 23 are connected to the lifting equipment. The cylinder 11 to be loaded is lifted by the lifting equipment, and the loading is completed. After loading is completed, the lifting equipment can be removed from the simulated rotor. Similarly, during unloading operations, the cylinder 11 to be unloaded can be unloaded from the simulated rotor using the lifting equipment. The design of the lifting mechanism 2 facilitates the combination of various simulated rotors and improves the testing efficiency of the hydraulic tilting device.

[0039] Alternatively, please refer to Figure 4 The reinforcing member 22 comprises multiple reinforcing ribs, which are evenly distributed along the circumference of the connecting plate 21 and intersect at their middle portions. Each reinforcing rib extends to the edge of the connecting plate 21 at both ends. This arrangement allows the cross-shaped reinforcing member 22 to evenly distribute the load around the connecting plate 21, avoiding localized stress concentration, thereby increasing the strength of the connecting plate 21 and preventing deformation of the connecting plate 21 during hoisting.

[0040] Preferably, the reinforcing member 22 includes four reinforcing ribs, and the lifting mechanism 2 includes four lifting lugs 23, which are respectively installed at the four free ends of the reinforcing member 22. This arrangement evenly distributes the load of the simulated rotor, and the force borne by the four lifting lugs 23 is relatively balanced, ensuring safety during the testing of the hydraulic tilting device and the loading or disassembly of the cylinder 11.

[0041] The following example, using N=4, illustrates the working principle of this hydraulic tilting device test fixture for replacing the wind-powered rotor under test in tilting tests:

[0042] The test fixture for the wind-powered rotor hydraulic tilting device includes a lifting mechanism 2 and four cylinders 11, which are designated as cylinder 1, cylinder 2, cylinder 3, and cylinder 4. The hydraulic tilting device is used to change the simulated rotor from an upright state to a tilted state, thus testing the tilting performance of the device.

[0043] When testing the hydraulic tilting device using the first type of simulated rotor, firstly connect the lifting mechanism 2 to the first cylinder to form the first type of simulated rotor. Then connect the lifting lug 23 to the lifting equipment. Use the lifting equipment to lift the first type of simulated rotor from the tilted state to the upright state. Finally, start the hydraulic tilting device to tilt the first type of simulated rotor, thus completing the first test of the hydraulic tilting device.

[0044] When testing the hydraulic tilting device using the second type of simulated rotor, the first type of simulated rotor, which was tilted, was first lifted into an upright position using hoisting equipment. Then, the hoisting mechanism 2 was removed from the main body of the simulation and connected to the second cylinder. The second cylinder was then lifted into an upright position and moved to a position coaxial with the first cylinder. The first cylinder and the second cylinder were connected using bolts and nuts to form the second type of simulated rotor. Finally, the hydraulic tilting device was activated to tilt the second type of simulated rotor, completing the second hydraulic tilting device test.

[0045] The principle of using the third type of simulated rotor to test the hydraulic tilting device is the same as that of the second type of simulated rotor, and will not be repeated here in this embodiment.

[0046] When testing the hydraulic tilting device using the fourth type of simulated rotor, the third type of simulated rotor, which was tilted, is first lifted into an upright position using hoisting equipment. Then, the hoisting mechanism 2 is removed from the main body of the simulation and connected to the fourth cylinder. The fourth cylinder is then lifted into an upright position and moved to a position coaxial with the third cylinder. The lower flange 1112 of the fourth cylinder is connected to the upper flange 1111 of the third cylinder using bolts and nuts to form the fourth type of simulated rotor. The hydraulic tilting device is then activated to tilt the fourth type of simulated rotor, completing the fourth hydraulic tilting device test. At this point, the fourth type of simulated rotor possesses the weight and center of gravity height of the wind-powered rotor under test, meaning that the load capacity of the hydraulic tilting device is sufficient to tilt the wind-powered rotor under test.

[0047] If you want to test the load weight limit of the hydraulic tilting device, you can gradually load the movable counterweight 115 to the 4th cylinder and test it through the hydraulic tilting device until the hydraulic tilting device fails. The weight of the test work at this time is the load weight limit of the hydraulic tilting device.

[0048] It should be understood that N can be 2, 3, 4, ..., and N can be any integer not less than 2. This embodiment and the accompanying drawings are only examples.

[0049] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
