[0001] The utility model relates to the technical field of marine engineering, in particular to a device for testing the resilience performance of a barbed claw. Background Art

[0002] One of the methods for the submarine cable to enter the wind turbine generator set from the seabed is to open a submarine cable opening at the bottom of the monopile foundation, insert the collision locking device into the submarine cable opening, and guide the submarine cable from inside to the wind turbine tower. After the collision locking device is installed in place, the barbed claws distributed around the periphery extend to prevent the collision locking device from sliding backward, and an interference flange is provided at the rear of the collision locking device, and the outer diameter of the interference flange is larger than the diameter of the submarine cable opening at the bottom of the monopile foundation, thereby fixing the collision locking device.

[0003] The barbed claw is extended through the elastic ring arranged below it. Relying on the function of compression and rebound of the elastic ring, when the collision locking device penetrates the bottom of the single pile foundation to open the submarine cable hole, the interference between the barbed claw and the wall of the submarine cable hole forces the elastic ring to compress. After the penetration is completed, the elastic ring rebounds quickly, stretching the barbed claw to clamp the collision locking device; and there are usually 12 groups of barbed claws distributed around the collision locking device, and the number of barbed claws to be penetrated must be more than 3 groups, and the penetrated barbed claws do not work at the same time, which requires the elastic ring to work normally in highly corrosive seawater throughout its life cycle to prevent the barbed claw from failing; for smooth construction, during the penetration process of the barbed claw, the barbed claw is compressed and lower than the outer surface of the collision locking device fixture, and there are certain requirements for the height of the barbed claw extended after the penetration is completed.

[0004] Therefore, it is extremely necessary to understand the range of compression and resilience performance degradation of the elastic ring after marine corrosion and to detect whether the extension and compression states of the barbed claws are qualified.

[0026] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0027] Reference Figure 1 and Figure 4 As shown, an embodiment of the barbed claw rebound performance test device of the utility model includes a base plate 1, a pressing assembly 2 is arranged on the base plate, a raised leg 3 is arranged on the base plate around the pressing assembly, and a rebound test seat 4 is arranged at the bottom of the raised leg. The base plate, the raised leg and the rebound test seat cooperate to form a test space. The pressing assembly provides a force to compress the barbed claw 112 or the elastic ring 111 in the test space. The pressing assembly is a cylinder or an electric cylinder. A compression in-place sensor 6 is arranged on the pressing assembly. The use cost of the cylinder is low, and the electric cylinder does not need an external device, which is more convenient. A rebound in-place sensor 5 is also arranged in the test space. The rebound in-place sensor is used to detect the rebound state of the barbed claw or the elastic ring. Through the cooperation of the pressing assembly and the rebound in-place sensor, the compression and rebound performance of the elastic ring, as well as the extension and compression state of the barbed claw can be quickly and accurately tested.

[0028] When the pressing assembly applies a compressive force, it needs to cooperate with the pressing head. Therefore, a linear bearing 7 and a guide rod 8 are also provided on the base plate. One end of the guide rod is connected to the end of the telescopic rod of the cylinder through a connecting block 20. The connecting block is used as a pressing head to ensure that the direction and position of the compressive force applied during the pressing process are accurate and reliable. Figure 3 shown.

[0029] A mounting bracket 12 is provided between the above-mentioned rebound in-position sensor and the base plate. The mounting bracket is L-shaped or Z-shaped. Mounting brackets of different shapes are selected according to different test objects. When testing the elastic ring, an L-shaped structure is used. Figure 2 As shown, the rebound in-position sensor is arranged toward the axial direction of the elastic ring, so that after the elastic ring is compressed and rebounded, its rebound height can be detected by the rebound in-position sensor. If it can be detected, it means that the rebound is in place, and if it is not detected, the rebound fails; when testing the barbed claws, a Z-type structure is adopted, referring to Figure 6 As shown, the rebound in-place sensor is arranged toward the barbed claw. After the barbed claw is extended, it can be detected by the rebound in-place sensor. If it can be detected, it means that it is extended to the right position. If it is not detected, it fails to extend. By replacing the structure of the mounting bracket, the installation position requirements of the rebound in-place sensor under different detection objects can be met. The mounting bracket is connected to the height adjustment rod 15, and the height adjustment rod is arranged on the C-type clamping block 16. The C-type clamping block is locked on the base plate. According to the different clamping positions of the height adjustment rod on the C-type clamping block, the height position of the rebound in-place sensor can be adjusted, and the operation is convenient.

[0030] For ease of use, a handle 17 is provided on the surface of the base plate. The number of handles can be two, which can be operated with both hands for easy placement. A control box 18 and an electrical box 19 are also installed on the base panel through a connecting bracket, so that the test operation can be automated and the requirements for testers are low.

[0031] Based on the above structure, in order to test the elastic ring, when used to test the elastic ring, the rebound test seat is selected as a mounting plate 9, and a fixing pin 10 is provided on the surface of the mounting plate located in the test space, and fixing pin seats 11 are provided at both ends of the fixing pin, and the fixing pin is used to press and fix the elastic ring on the mounting plate. And the pressing component uses a cylinder.

[0032] When assembling the device, first place the cylinder and the linear bearing on the corresponding mounting holes of the base plate. A threaded hole is processed on one end of the connecting block, and a through hole, an open groove and a bolt hole are processed on the other end. Screw the connecting block into the head of the cylinder rod. After the connecting block is screwed in to a certain depth, the guide rod is inserted into the through hole along the direction of the linear bearing, and the bolt is screwed in to hold the guide rod tightly. The number of lifting legs can be 4, distributed in pairs on one side, one end of the lifting leg is inserted into the corresponding hole of the base plate and locked, and the other end is used to install the corresponding rebound test seat, which is the mounting plate here. Then select the corresponding mounting bracket according to the test item, and assemble the height adjustment rod, mounting bracket and rebound in-place sensor as a sensor assembly. Refer to Figure 2As described in the corresponding part; a C-type clamp block for fixing the sensor assembly is processed with a bolt hole at one end, and a through hole, an open slot and a bolt hole at the other end. It is first installed on the corresponding threaded hole of the base plate and fixed with bolts. The height adjustment rod of the sensor assembly is passed through the through holes of the base plate and the C-type clamp block from the bottom of the base plate to the top. After the height of the sensor assembly is adjusted as required, screw in the bolts and hold it tightly;

[0033] Then, the compression and rebound performance of the elastic ring are tested: first, the mounting plate and the four lifting legs are locked and connected as one, and then the two fixing pin seats are placed on the corresponding threaded holes of the mounting plate and fixed by bolts; the elastic ring is placed on the mounting plate between the two fixing pin seats, and the fixing pin is inserted into the first fixing pin seat, the elastic ring and the second fixing pin seat in sequence, and the fixing pin is locked by the fixing pin seat; after the compression in-place sensor and the rebound in-place sensor are adjusted to the appropriate position, click the start button, the cylinder automatically extends and retracts, and after a certain number of reciprocating movements, the compression and rebound states of the elastic ring are judged to be qualified according to the detection data of the rebound in-place sensor (the elastic ring should undergo salt spray corrosion test as required);

[0034] Based on the above structure, the barbed claw is tested. When used to test the barbed claw, the rebound test seat is a magnetic seat 13. The assembly of the device can refer to the above method. The magnetic seat is used to connect with the surface of the collision locking device 113 by magnetic attraction. Figure 4 As shown, since the surface of the collision locking device is arc-shaped, a horizontal pad can be set on the magnetic base so that there is a certain angle between the magnetic base and the raised legs. The two magnetic bases can fit and be adsorbed and fixed with the arc-shaped surface to ensure stability during testing.

[0035] After the device is installed, the extension and compression status of the barbed claw are detected: first fix the horizontal pad on the magnetic base, and connect the lifting leg to the horizontal pad; after the compression in-place sensor and the rebound in-place sensor are adjusted to the appropriate position, move the whole to the corresponding position of the collision locking device through the handle, turn on the magnetic base switch and firmly adsorb it on the surface of the collision locking device; click the start button, the cylinder automatically extends and retracts, and the cylinder applies downward pressure to force the elastic ring to compress. When the cylinder rod cannot be extended, the compression in-place sensor detects whether the barbed claw is compressed in place, the cylinder rod retracts, and the rebound in-place sensor detects whether the barbed claw is extended in place, and the corresponding indicator light can be used to display whether the test is qualified.

[0036] Since the rebound in-place sensor is arranged vertically, an avoidance hole 14 for avoiding the rebound in-place sensor is arranged on the base plate to ensure effective installation of the rebound in-place sensor in a limited space.

[0037] In summary, in the device of the present application, all main components are installed on the base plate, the replacement of the rebound test seat is also very simple, the operability is high, the versatility is good, the sensor is used to detect the performance of the elastic ring and the function of the barbed claw, the reliability is high, and no manual intervention is required; and its main components can be preferably made of aluminum materials, the structure is light, and the centralized arrangement on the base plate can improve the mobility of the device; the device has a compact structure and a small size, and does not require any external device connection except the air source, and the cylinder can also be replaced by an electric cylinder, so that no external device connection is required; it adopts automated electrical control, and all tests can be completed with just one button, which has low requirements for testers and can be tested in batches;

[0038] The above embodiments are only preferred embodiments for fully illustrating the present utility model, and the protection scope of the present utility model is not limited thereto. Equivalent substitutions or changes made by technicians in this technical field on the basis of the present utility model are all within the protection scope of the present utility model.
