Description

Technical Field

[0001] This utility model relates to the field of wind turbine testing technology, specifically to a wind turbine testing cooling test bench device. Background Technology

[0002] The wind turbine cooling test bench is designed to simulate and test the cooling performance of wind turbines during actual operation. It primarily simulates the heat generated by a wind turbine during operation and dissipates this heat through a cooling system to test the system's performance and efficiency. The bench typically includes a heat source simulating the wind turbine, a cooling system, measuring equipment, and a control system. During the test, the simulated heat source generates heat, mimicking the internal heating conditions of the wind turbine. After the cooling system starts, the coolant circulates under the action of a circulating pump. The coolant absorbs heat from the heat source, flows through the cooler for heat dissipation, and then returns to the heat source to continue circulating. By monitoring and recording parameters such as temperature, pressure, and flow rate during the test, the performance and efficiency of the cooling system can be evaluated.

[0003] Since a performance test bench needs to test the performance of multiple generators, the disassembly and assembly of generators is quite troublesome. It is necessary to rebuild the support frame or replace the support components according to different generators, which is quite troublesome. Therefore, it is particularly important to improve the existing test bench equipment and design a new type of wind turbine generator test cooling test bench equipment to solve the above-mentioned technical defects and improve the practicality of the overall test bench equipment. Utility Model Content

[0004] The purpose of this utility model is to provide a wind turbine generator test cooling test bench device. Through the overall design, it can easily fix the generator when it is fixed, and it can adapt to generators of different specifications. The overall structure is simple and practical, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A wind turbine generator test cooling test bench device includes a test bench body, a generator is provided on the top of the test bench body, and limiting components are provided at both ends of the generator.

[0007] The limiting component is used to limit the generator. The limiting component consists of a movable seat, two sets of limiting blocks, a support seat and a drive screw.

[0010] As a preferred embodiment of this utility model, the movable seat is designed in an inverted trapezoidal shape, and a threaded cylinder is rotatably connected to the bottom of the movable seat. The threaded cylinder is threadedly connected to the drive screw, and the drive end of the first drive motor is fixedly connected to the outside of the drive screw.

The moving seat is moved downwards, and when the guide groove is moved, the sliding wheel allows the limiting block to rotate, bringing the front ends of the two sets of limiting blocks closer together, thus limiting the generator.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] Example: Please refer to Figures 1-5 This utility model provides a technical solution:

[0024] A wind turbine generator test cooling test bench device includes a test bench body 1, a generator 2 is provided on the top of the test bench body 1, and limiting components 3 are provided at both ends of the generator 2. The limiting components 3 are installed inside the test bench body 1. A fixing seat 4 is fixedly connected to the front end of the test bench body 1, and a connecting seat 5 is provided on the outside of the fixing seat 4. The connecting seat 5 is fixedly installed on the top of the test bench body 1. Cooling devices 6 are provided at both ends of the test bench body 1.

[0025] The limiting component 3 is used to limit the generator 2. The limiting component 3 consists of a movable seat 7, two sets of limiting blocks 8, a support seat 9 and a drive screw 10. The movable seat 7 is slidably connected to the top of the test bench body 1 and located at the bottom of the generator 2. The two sets of limiting blocks 8 are located at both ends of the movable seat 7. The support seat 9 is fixedly connected to the top of the movable seat 7. The drive screw 10 is rotatably connected to the inside of the test bench body 1 and located at the bottom of the movable seat 7.

[0026] Furthermore, guide grooves 11 are provided at both ends of the movable seat 7. The limiting block 8 extends into the interior of the guide groove 11 and is rotatably connected to the sliding wheel 12. The limiting block 8 and the guide groove 11 are slidably connected. When the limiting block 8 and the guide groove 11 are connected, the sliding wheel 12 is connected to the guide groove 11. When the movable seat 7 moves and drives the guide groove 11 to move, the limiting block 8 can rotate in cooperation with the sliding wheel 12.

[0027] The limiting block 8 and the support base 9 are both designed with an arc shape. Multiple sets of buffer strips 13 are fixedly connected to the inner side of the limiting block 8 and the support base 9. The arc shape of the limiting block 8 and the support base 9 allows them to contact the surface of the generator 2. When the limiting block 8 and the support base 9 are in contact with the surface of the generator 2, the multiple sets of buffer strips 13 can increase the buffer distance between them and the generator 2, preventing damage to the surface of the generator 2.

[0028] Secondly, the movable seat 7 has an inverted trapezoidal structure design. A threaded cylinder is rotatably connected to the bottom of the movable seat 7. The threaded cylinder is threadedly connected to the drive screw 10. The drive end of the first drive motor is fixedly connected to the outside of the drive screw 10. When the first drive motor is started, the drive screw 10 is rotated, causing the threaded cylinder to move and thus the movable seat 7 to move.

[0029] Furthermore, the drive end of generator 2 is rotatably connected to both the fixed base 4 and the connecting base 5. A first synchronous pulley 14 is rotatably connected to the end of the connecting base 5 furthest from the fixed base 4. The drive end of generator 2 is fixedly connected to the first synchronous pulley 14. A synchronous belt 15 is provided on the outer side of the first synchronous pulley 14. A second synchronous pulley 16 is provided on the end of the synchronous belt 15 furthest from the first synchronous pulley 14. The second synchronous pulley 16 is rotatably connected to the test bench body 1. The drive end of a second drive motor is fixedly connected inside the second synchronous pulley 16. A bracket 17 is fixedly connected to the outer side of the test bench body 1. A guide wheel 18 is rotatably connected to the end of the bracket 17 closest to the synchronous belt 15. The guide wheel 18 guides the synchronous belt 15 to prevent it from shifting. It rotatably connects the drive end of the generator 2 to the fixed base 4 and the connecting base 5, so that it can be fixedly connected to the first synchronous pulley 14. The second drive motor is started, which drives the second synchronous pulley 16 to rotate, causing the synchronous belt 15 to shift and drive the first synchronous pulley 14 to rotate, thus rotating the drive end of the generator 2 to perform simulated operation. The generator 2 generates heat, which is dissipated by the cooling device 6. By monitoring and recording parameters such as temperature, pressure, and flow rate during the test, the performance and efficiency of the cooling system can be evaluated.

[0030] In this embodiment, the specific implementation scenario is as follows: In actual use, the generator 2 is placed on top of the test bench body 1, so that the generator 2 can contact multiple sets of limiting blocks 8. The first drive motor is started, driving the drive screw 10 to rotate, causing the threaded cylinder to move, which in turn causes the moving seat 7 to move. When the moving seat 7 moves downward, it causes the guide groove 11 to move, and with the help of the sliding wheel 12, the limiting blocks 8 can rotate, bringing the front ends of the two sets of limiting blocks 8 closer together, so as to limit the generator 2. The drive end of the generator 2 is then rotated and connected to the fixed seat 4 and the connecting seat 5. The second drive motor is connected to the first synchronous pulley 14 for fixed connection. The second synchronous pulley 16 is started, causing the synchronous belt 15 to rotate, which in turn causes the first synchronous pulley 14 to rotate, thus rotating the drive end of the generator 2 to simulate operation. The generator 2 generates heat, which is dissipated by the cooling device 6. By monitoring and recording parameters such as temperature, pressure, and flow rate during the test, the performance and efficiency of the cooling system can be evaluated. Compared with existing test bench devices, this invention improves the overall practicality of the test bench device through its design.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
