It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0030] In the description of this embodiment, the terms "upper", "lower", "right", etc., directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplification of operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0031] On the one hand, the present embodiment provides a wind-assisted rotor hydraulic dumping device test tool, which is used to replace the wind-assisted rotor to be tested for dumping test.

[0032] Please refer to Figures 1 to 4The wind-assisted rotor hydraulic dumping device test tooling includes a suspension mechanism 2 and N cylinders 11, the suspension mechanism 2 is used to connect with the lifting equipment, and the suspension mechanism 2 can be connected with any cylinder 11, N is an integer not less than 2; both ends of each cylinder 11 are provided with a connecting portion 111, and the connecting portions 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 suspension mechanism 2 and the N cylinders 11 can be combined into N kinds of simulated rotors; the i-th simulated rotor is spliced ​​by the suspension mechanism 2 and the i-th cylinder 11, wherein, When i is equal to 1, the cylinder is the first cylinder, and the suspension 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 respectively the first cylinder...the i-th cylinder, the first cylinder...the i-th cylinder are coaxially connected in sequence to form the main simulation part 1, and the suspension mechanism 2 is connected to the cylinder 11 at one end of the main simulation part 1; the center of gravity height of the first cylinder is L1, the center of gravity height of the N-th cylinder is L3, and the center of gravity heights of the remaining cylinders 11 are all L2, L1>L2>L3, and the center of gravity height and weight of the N-th simulated rotor are the same as those of the wind-assisted thruster rotor to be tested. Among the remaining simulated rotors, from the N-1-th simulated rotor to the 1st simulated rotor, the weight and center of gravity height of the simulated rotor are gradually reduced. With such a configuration, when the hydraulic dumping device is tested, the first simulated rotor is first formed by the first cylinder to perform the first hydraulic dumping device test, and then the first cylinder and the second cylinder are connected to form the second simulated rotor to perform the second hydraulic dumping device test, and so on. The hydraulic dumping device is subjected to a graded loading test, and the center of gravity height of the first cylinder is set to the maximum, so that during the test, as the number of tests increases, the center of gravity height of the simulated rotor increases and tends to gradually decrease, which can further ensure the safety of the test. The center of gravity heights of the second cylinder to the N-1 cylinder are the same, and the center of gravity height changes of the second simulated rotor to the N-1 simulated rotor are the same, which is conducive to identifying the changing trend of the performance parameters of the hydraulic dumping device caused by the change of the center of gravity height each time the loading is carried out, and is convenient for theoretical analysis. The center of gravity height of the Nth cylinder is set to the minimum, and at this time, the center of gravity height of the simulated rotor reaches the rated center of gravity height of the hydraulic dumping device, that is, it has the same center of gravity height as the wind-assisted rotor to be tested, which is conducive to evaluating the reliability of the hydraulic dumping device.

[0033] When conducting the hydraulic dumping device test, the test is carried out in sequence starting from the first simulated rotor. Specifically, when the i-th simulated rotor is tested, if the test is qualified, the subsequent simulated rotors are tested until the N-th simulated rotor is tested. If the N-th simulated rotor is tested, it indicates that the hydraulic dumping test of the wind-assisted rotor to be tested is qualified; if the i-th simulated rotor test is unqualified, there is no need to perform dumping tests on the subsequent simulated rotors, and it indicates that the dumping test of the wind-assisted rotor to be tested is unqualified, and the weight and center of gravity height of the wind-assisted rotor to be tested should not exceed the weight and center of gravity height corresponding to the i-th simulated rotor. Therefore, the wind-assisted rotor hydraulic dumping device test fixture can ensure the safety and reliability of the test when used for the dumping device test.

[0034] Optionally, see Figure 1 , the weight of the first cylinder is G1, the weight of the Nth cylinder is G3, and the weights of the remaining cylinders 11 are all G2, G1>G2>G3. The hydraulic dumping device is subjected to a graded loading test, and the weight of the first cylinder is set to the maximum, so that during the test, as the number of tests increases, the weight added by the simulated rotor tends to gradually decrease, which can further ensure the safety of the test. The weights of the second cylinder to the N-1th cylinder are the same, and the weight changes from the second simulated rotor to the N-1th simulated rotor are the same, which is conducive to identifying the changing trend of the performance parameters of the hydraulic dumping device brought about by each change in loading weight, and is convenient for theoretical analysis. The weight of the Nth cylinder is set to the minimum, at which time the weight of the simulated rotor reaches the rated weight of the hydraulic dumping device, that is, it has the same weight as the wind-assisted rotor to be tested, which is conducive to evaluating the reliability of the hydraulic dumping device.

[0035] For details, please refer to Figures 1 to 3 , along the direction in which the cylinders 11 of the main simulation part 1 are connected in sequence, the connecting parts 111 arranged at both ends of each cylinder 11 are respectively an upper flange 1111 and a lower flange 1112; the wind-assisted rotor hydraulic dumping device test fixture also includes a plurality of bolts and a plurality of nuts. In any two cylinders 11 connected to each other, the plurality of bolts sequentially pass through the lower flange 1112 of one cylinder 11 and the upper flange 1111 of the other cylinder 11, and the plurality of bolts and the plurality of nuts are threadedly connected in a one-to-one correspondence. With such a configuration, the installation and disassembly operations between the cylinders 11 are simple, and when conducting hydraulic dumping tests under different working conditions, the corresponding simulated rotor can be combined according to the needs, which shortens the test preparation time and improves the test efficiency.

[0036] Preferably, a plurality of bolts are evenly spaced along the circumferential direction of the connecting portion 111 to ensure that the two interconnected cylinders 11 are evenly stressed along the circumferential direction of the connecting portion 111, thereby ensuring that the two interconnected cylinders 11 are directly connected firmly and reliably.

[0037] Optionally, see Figure 2 The cylinder 11 includes a shell 112, a support plate 113 and a fixed counterweight 114. The support plate 113 is arranged in the shell 112, and a limited space is formed between the support plate 113 and the upper flange 1111. The fixed counterweight 114 is arranged in the limited space. In this way, the design of the limited space can effectively prevent the fixed counterweight 114 from shifting inside the cylinder 11. Avoid shifting of the counterweight during the test, especially when the simulated rotor is tipping, which affects the accuracy and reliability of the test.

[0038] Furthermore, the limited space for placing the fixed counterweight 114 is located at the top of the cylinder 11. Compared with the fixed counterweight 114 set at other positions of the cylinder 11, the center of gravity height of the cylinder 11 is increased, which is beneficial to reducing the size of the test tooling of the wind-assisted rotor hydraulic dumping device and facilitating the assembly of the equipment and the actual test operation.

[0039] For further information, please refer to Figure 3 The wind-assisted rotor hydraulic dumping device test fixture further includes a plurality of movable counterweights 115. In the i-th simulated rotor, the movable counterweights 115 are used to selectively load on the top of the i-th cylinder 11. Specifically, the i-th simulated rotor has a weight and a center of gravity height that simulates a real wind-assisted rotor. With such a configuration, after the i-th simulated rotor is used to perform a full load test of the hydraulic dumping device, the weight and the 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 dumping device.

[0040] Preferably, please refer to Figure 1 and Figure 2 The cylinder 11 further includes a plurality of reinforcing ribs 116, which are arranged at intervals on the outer periphery of the shell 112, and extend along the axis direction of the shell 112. The arrangement of the reinforcing ribs 116 can strengthen the rigidity of the cylinder 11, thereby enhancing the ability of the cylinder 11 to resist deformation. This prevents the cylinder 11 from being deformed too much during the dumping process, ensures the shape and dimensional stability of the simulated rotor, and makes the test results more accurate and reliable.

[0041] Optionally, see Figure 1 and Figure 4, the hanging mechanism 2 includes a connecting plate 21, a reinforcement 22 and a plurality of lifting ears 23. In the i-th simulated rotor, the connecting plate 21 is detachably connected to the connecting portion 111 of the i-th cylinder, the reinforcement 22 is arranged on the connecting plate 21, and the plurality of lifting ears 23 are arranged on the reinforcement 22. The lifting ears 23 are used to connect with the lifting equipment. Preferably, the hanging mechanism 2 is also provided with an annular reinforcement plate to strengthen the strength of the connecting plate 21, and the annular reinforcement plate and the reinforcement 22 are arranged on the same side of the connecting plate 21. With such a configuration, when performing a loading operation, the connecting plate 21 is connected to the cylinder 11 to be loaded, the lifting ears 23 are connected to the lifting equipment, and the cylinder 11 to be loaded is lifted by the lifting equipment, and the loading is completed. After the loading is completed, the hanging device can be removed from the simulated rotor. When performing an unloading operation, the cylinder 11 to be unloaded can be unloaded from the simulated rotor by the hanging device. The setting of the hanging mechanism 2 facilitates the combination of multiple simulated rotors and improves the test efficiency of the hydraulic dumping device.

[0042] Optionally, see Figure 4 The reinforcement member 22 includes a plurality of reinforcement ribs, which are evenly distributed along the circumferential direction of the connecting plate 21, and the middle of the plurality of reinforcement ribs intersect, and the two ends of each reinforcement rib extend to the edge of the connecting plate 21. In this way, the cross-shaped reinforcement member 22 can evenly distribute the load around the connecting plate 21, avoid local stress concentration, and thus increase the strength of the connecting plate 21, and avoid deformation of the connecting plate 21 during the lifting process.

[0043] Preferably, the reinforcement member 22 includes four reinforcement ribs, and the suspension mechanism 2 includes four lifting ears 23, which are respectively installed at the four free ends of the reinforcement member 22. In this way, the load of the simulated rotor is evenly dispersed, and the forces borne by the four lifting ears 23 are relatively balanced, thereby ensuring the safety of the hydraulic dumping device during the test, loading or disassembly of the cylinder 11.

[0044] On the other hand, the present embodiment provides a method for testing a hydraulic dumping device for a wind-assisted rotor, the method for testing a hydraulic dumping device for a wind-assisted rotor being implemented by the above-mentioned test tooling for the hydraulic dumping device for a wind-assisted rotor, the method for testing a hydraulic dumping device for a wind-assisted rotor sequentially performing hydraulic dumping tests on the first to the Nth simulated rotors;

[0045] Wherein, when the hydraulic dumping test is performed on the i-th simulated rotor, if the test is qualified, the hydraulic dumping test is continued on the i+1-th simulated rotor; if the test is unqualified, the hydraulic dumping test is stopped on the subsequent simulated rotors;

[0046] The hydraulic dumping test on the i-th simulated rotor includes:

[0047] The i-th simulated rotor is connected to the lifting mechanism 2 at the top of the i-th simulated rotor through the lifting equipment, so that the i-th simulated rotor is in an upright state; under the action of the hydraulic dumping device, the i-th simulated rotor is dumped.

[0048] Taking N=4 as an example, the following describes the working principle of the wind-assisted rotor hydraulic dumping device test fixture used to replace the wind-assisted rotor to be tested for dumping test:

[0049] The wind-assisted rotor hydraulic dumping device test fixture comprises a suspension mechanism 2 and four cylinders 11, wherein the four cylinders 11 are respectively a first cylinder, a second cylinder, a third cylinder and a fourth cylinder. The hydraulic dumping device is used to change the simulated rotor from an upright state to a dumping state, and the dumping performance of the hydraulic dumping device is tested.

[0050] When using the first simulated rotor to perform the hydraulic dumping device test, first connect the lifting mechanism 2 to the first cylinder to form the first simulated rotor, then connect the lifting ear 23 to the lifting equipment, and use the lifting equipment to lift the first simulated rotor in the dumping state to an upright state, and finally start the hydraulic dumping device to dump the first simulated rotor, thereby completing the first hydraulic dumping device test.

[0051] When using the second simulated rotor to test the hydraulic dumping device, first lift the first simulated rotor in the dumped state to an upright state using the lifting equipment, then remove the lifting mechanism 2 from the simulated main body, connect the lifting mechanism 2 to the second cylinder, lift the second cylinder to an upright state and move it to a position coaxial with the first cylinder, connect the first cylinder and the second cylinder by bolts and nuts to form a second simulated rotor, and finally start the hydraulic dumping device to dump the second simulated rotor to complete the second hydraulic dumping device test.

[0052] The principle of using the third type of simulated rotor to test the hydraulic dumping device is the same as that of the second type of simulated rotor, and this embodiment will not be repeated here.

[0053] When the fourth type of simulated rotor is used for the hydraulic dumping device test, the third type of simulated rotor in the dumping state is first lifted to an upright state by the lifting equipment, and then the lifting mechanism 2 is removed from the simulated main body, and the lifting mechanism 2 is connected to the fourth cylinder, and the fourth cylinder is lifted to an upright state and moved to a position coaxial with the third cylinder, and the lower flange 1112 of the fourth cylinder is connected to the upper flange 1111 of the third cylinder by bolts and nuts to form the fourth type of simulated rotor, and the hydraulic dumping device is started to dump the fourth type of simulated rotor, completing the fourth hydraulic dumping device test. At this time, the fourth type of simulated rotor has the weight and center of gravity height of the simulated wind-assisted rotor to be tested, that is, the load capacity of the hydraulic dumping device can complete the dumping of the wind-assisted rotor to be tested.

[0054] If you want to test the loading weight limit of the hydraulic dumping device later, you can gradually load the movable counterweight 115 to the 4th cylinder and test it through the hydraulic dumping device until the hydraulic dumping device fails. At this time, the weight of the test work is the loading weight limit of the hydraulic dumping device.

[0055] It should be understood that N can be 2, 3, 4, ..., as long as N is an integer not less than 2, and this embodiment and the accompanying drawings are only examples.

[0056] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to list all the embodiments here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the claims of the present invention.
