In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0035] The present invention provides an efficient wind power cable torsion test device, such as Figure 1 and Figure 2 As shown, the wind power cable torsion test device includes a mounting frame 10, a torsion drive module 20 and a temperature control box 30, wherein the torsion drive module 20 is arranged on the mounting frame 10, and the torsion drive module includes a plurality of rotating fixtures 200 and a driving source 21, and the driving source 21 is transmission-connected with the plurality of rotating fixtures 200, and the driving source 21 can drive the plurality of rotating fixtures 200 to rotate synchronously, and the temperature control box 30 is located below the torsion drive module 20, and a lower opening for the lower part of the sample cable is provided on the top of the temperature control box, and the temperature inside the temperature control box 30 is adjustable, and a fixed bracket is also fixed at the bottom of the temperature control box 30, and the fixed bracket is used to fix the lower end of the sample cable.

[0036] The beneficial effects of the wind power cable torsion test device of the present invention are as follows: when in use, the upper ends of the plurality of sample cables are fixedly connected to the plurality of rotating fixtures 200 on the torsion drive module 20, respectively, and the lower ends of the sample cables are lowered from the lower opening at the top of the temperature control box 30 into the temperature control box 30, and the lower ends of the sample cables are fixedly connected to the fixed bracket at the bottom of the temperature control box 30, thereby achieving effective constraints on both ends of each sample cable, and then adjusting the temperature in the temperature control box 30 to the temperature required for the test, and starting the driving source 21 to drive the plurality of rotating fixtures 200 to rotate synchronously, so that the plurality of sample cables can be synchronously driven to perform torsion tests. Therefore, compared with the prior art, the wind power cable torsion test device of the present invention can greatly improve the test efficiency and significantly shorten the overall test cycle.

[0037] Further, in order to facilitate the connection and removal of the sample cable on the rotating fixture 200, as shown in FIG. Figure 1 As shown, in this embodiment, the wind power cable torsion test device further includes a lifting drive device 40, and the torsion drive module 20 is slidably arranged on the mounting frame 10, and the lifting drive device 40 can drive the torque drive module 20 to move up and down. In this way, when the sample cable is connected to or removed from the rotating fixture 200, the lifting drive device 40 can drive the torsion drive module 20 to move upward along the mounting frame 10, so that the rotating fixture 200 of the torsion drive module 20 rises to a certain height relative to the temperature control box 30, so that it is convenient for the operator to connect or remove the sample cable on the rotating fixture 200.

[0038] Further, such as Figure 1 and Figure 2 As shown, in this embodiment, the driving source 21 includes a motor box 211 and a gear box 212. The gear box 212 is fixedly connected to the bottom of the motor box 211. A driving motor 2110 is provided in the motor box 211. A driving gear 2120 and three driven gears 2121 are rotatably provided in the gear box 212. The driving motor 2110 is transmission-connected to the driving gear 2120 via a driving shaft, and the driving gear 2120 is meshed with the three driven gears 2121. A rotating fixture 200 is fixedly connected to each of the three driven gears 2121. Specifically, a vertically extending slide rail is provided on the mounting frame 10, and a slider that slidably cooperates with the slide rail is provided on the motor box 211. The lifting drive device 40 is connected to the motor box. Before the test, when the sample cable is connected to the rotating fixture 200, as shown in FIG. Figure 2As shown, the motor box 211 is driven by the lifting drive device 40 to move upward along the slide rail on the mounting frame 10. Since the gear box 212 is fixedly connected to the motor box 211, it can drive the gear box 212 to move upward together, and then drive the rotating fixture 200 fixedly connected to the driven gear 2121 to rise together, and the rotating fixture 200 is raised to a certain height with the temperature control box 30, so that it is convenient for the operator to connect the sample cable to the rotating fixture 200; after the upper end of the sample cable is fixedly connected to the rotating fixture 200, the lower end of the test cable is raised from the temperature control box 30. The lower opening on the top of the control box 30 is lowered into the interior of the temperature control box 30 and fixedly connected to a fixed bracket at the bottom of the temperature control box 30, thereby achieving effective constraints on both ends of each sample cable. Then, the motor box 211 is driven downward by the lifting drive device 40, so that the three rotating clamps 200 extend into the lower opening, and the gear box 212 is in contact with the top of the temperature control box 30. Therefore, during the test, the gear box 212 can cover the lower opening on the top of the temperature control box 30, thereby ensuring the stability of the temperature in the temperature control box 30 and thus ensuring the accuracy of the test.

[0039] Furthermore, if Figure 3 and Figure 4 As shown, in this embodiment, the driving gear 2120 has the same diameter as the three driven gears 2121. This arrangement ensures that the driving gear 2120 and the three driven gears 2121 can maintain perfect synchronization during the rotation process, that is, both the rotation angle and the rotation speed are exactly the same, so that each torsion test can be performed under the same reference conditions.

[0040] Furthermore, in this embodiment, the rotating clamp 200 includes a first sub-clamp block and a second sub-clamp block, and the first sub-clamp block and the second sub-clamp block are connected by bolts. When connecting the sample cable to the rotating clamp 200, the bolts connecting the first sub-clamp block and the second sub-clamp block are loosened, and then the upper end of the sample cable is clamped between the first sub-clamp block and the second sub-clamp block, and then the bolts are tightened to clamp and fix the upper end of the sample cable between the first sub-clamp block and the second sub-clamp block. The structure is simple, the connection strength is high, and it is easy to disassemble and assemble.

[0041] Further, in this embodiment, the temperature control box 30 includes an insulation box and a temperature control system. Specifically, the temperature control system includes a temperature controller, a heating system, a refrigeration system and a temperature sensor. The heating system, the refrigeration system and the temperature sensor are all connected to the temperature controller in communication. The heating system is used to heat the inside of the insulation box, the refrigeration system is used to cool the inside of the insulation box, and the temperature sensor is used to monitor the temperature in the insulation box in real time. During the test, the temperature sensor monitors the temperature in the insulation box in real time and feeds back the real-time monitored temperature to the temperature controller. The temperature controller controls the operation of the heating system or the refrigeration system according to the real-time monitored temperature data and the pre-set temperature data. Exemplarily, when the real-time monitored temperature is lower than the pre-set temperature, the temperature controller controls the operation of the heating system; when the real-time monitored temperature is higher than the pre-set temperature, the temperature controller controls the operation of the refrigeration system. This structural design ensures that the temperature control box can accurately simulate the required ambient temperature and provide reliable conditions for the performance test of the wind turbine cable.

[0042] Specifically, in this embodiment, the heating system includes an electric heating pipe disposed in the heat preservation box, and the heat preservation box can be heated by the electric heating pipe. The refrigeration system can use compressor refrigeration technology to reduce the temperature in the box by circulating the refrigerant in the evaporator, condenser and other components.

[0043] Furthermore, in this embodiment, the temperature control box also includes an alarm system, which is in communication with the temperature sensor. During the test, when the temperature monitored by the temperature sensor is abnormal or the temperature sensor fails, the alarm system can send an alarm signal in time, so as to notify the staff to stop the test in time, thereby ensuring the safety of the test. Specifically, in this embodiment, the alarm system is preferably a buzzer light.

[0044] Furthermore, in order to improve the uniformity of the temperature inside the insulation box during the test, in this embodiment, the temperature control box also includes an air circulation system, which is used to evenly distribute hot air or cold air into the insulation box, thereby avoiding the problem of local temperature unevenness.

[0045] Furthermore, in order to improve the thermal insulation performance of the thermal insulation box, in the present embodiment, the thermal insulation box includes two layers, an inner layer and an outer layer, wherein the inner layer of the thermal insulation box is an insulation layer, and the material of the insulation layer is high-density polyurethane, which has good thermal insulation performance, little temperature change, high strength, not easy to deform, and can bear a certain mechanical load; the outer layer of the thermal insulation box is an outer shell arranged outside the insulation layer, and the material of the outer shell is a stainless steel plate, which has a beautiful appearance and is not easy to rust.

[0046] In summary, the highly efficient wind power cable torsion test device of the present invention can greatly improve the test efficiency and significantly shorten the overall test cycle. Therefore, the present invention effectively overcomes various shortcomings in the prior art and has high industrial utilization value.
