Technical Field

[0001] The utility model relates to the technical field of protection components, in particular to a protection component and a fault warning system for the main drive chain of a wind turbine generator set. Background Technique

[0002] The fault warning system for the main drive chain of a wind turbine generator set is a technical solution for monitoring and predicting the health status of the main drive chain components in a wind power generation unit.

[0003] At present, the fault warning system for the main drive chain of a wind turbine generator set uses sensors such as vibration sensors and temperature sensors to monitor the operating conditions of each component of the main drive chain in real time. Then, these sensors will transmit the data they collect to the control center, and the control center will determine whether to issue a warning message after comparing the error tolerance range. Most of these sensors are directly fixed on the main drive chain components by bolts.

[0004] However, during long-term use, since the main drive chain will generate vibrations within the allowable range during operation, these continuous vibrations may cause the bolts to loosen or even fall off without notice, resulting in the sensor possibly detaching from the mounting surface during the operation of the main drive chain, thus affecting the normal operation of the wind turbine. Therefore, the utility model proposes a protection component and a fault warning system for the main drive chain of a wind turbine generator set to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a protection component and a fault warning system for the main drive chain of a wind turbine generator set to solve the problem that the installation bolts of the fault warning system loosen or even fall off without notice due to the long-term continuous vibrations within the allowable error range generated by the main drive chain, resulting in the sensor possibly detaching from the mounting surface during the operation of the main drive chain and affecting the normal operation of the wind turbine.

[0025] Please refer to Figures 1 to 4 , the present utility model provides a technical solution:

[0026] Embodiment 1, a protection component, the protection component includes: a mounting base 1 and a sensor main body 2.

[0027] Specifically, one end of the mounting base 1 is fixedly connected to the sensor main body 2. A plurality of bolt holes 11 are provided on one side of the mounting base 1. One end of the bolt hole 11 is threadedly inserted with a fastening bolt 3. By threadedly inserting the fastening bolt 3, the bolt holes 11 on the mounting base 1, and the mounting groove on the equipment mounting surface, the mounting base 1 and the sensor main body 2 can be fixed on the equipment mounting surface. A plurality of mounting plates 4 corresponding to the fastening bolts 3 in terms of position and quantity are slidably connected to the side surface of the mounting base 1. A spring 6 is fixedly connected between the mounting plate 4 and the mounting base 1. A limiting plate 5 is fixedly connected to the side of the mounting plate 4 close to the fastening bolt 3. The limiting plate 5 is arranged in a "V" shape. The spring 6 will push the mounting plate 4 and the limiting plate 5 to slide, and then the "V"-shaped limiting plate 5 will be clamped with the fastening bolt 3, thereby effectively restricting the rotation of the fastening bolt 3, so that the mounting base 1 and the sensor main body 2 are installed more stably.

[0028] To better install the mounting plate 4, a plurality of fixing plates 7 arranged in an "L" shape are fixedly connected to the side surface of the mounting base 1 of the present application. The spring 6 is located between the mounting plate 4 and the fixing plate 7 and the mounting plate 4 is slidably connected to the fixing plate 7. The "L"-shaped fixing plate 7 can provide more installation space for the mounting plate 4, so that the mounting plate 4 has enough space to cooperate with the installation of the fastening bolt 3.

[0029] To make the installation of the mounting plate 4 more stable, a positioning slider 41 arranged in a "T" shape is fixedly connected to one end of the mounting plate 4 of the present application. A sliding groove 71 for the positioning slider 41 to slide through is provided through one side of the fixing plate 7. Through the cooperation of the positioning slider 41 and the sliding groove 71, the sliding track of the mounting plate 4 can be more accurate, so that the limiting plate 5 can better fit the fastening bolt 3, and at the same time, the mounting plate 4 can be prevented from shaking when sliding.

[0030] To better install the fastening bolt 3, a positioning rod 9 is slidably connected to one end of the fixing plate 7 of the present application. After the positioning rod 9 rotates and slides, it is inserted into the mounting plate 4. Before installing the fastening bolt 3, first control the mounting plate 4 to slide away from the mounting base 1, then rotate the positioning rod 9, and then slide the positioning rod 9 into the mounting plate 4, thereby restricting the mounting plate 4 from continuing to slide, so as to vacate the installation space for the fastening bolt 3.

[0031] For the convenience of installing the positioning rod 9, one end of the fixing plate 7 of the present application is fixedly connected with a guide rod 72. The positioning rod 9 is arranged in an "L" shape and one end of the positioning rod 9 is fixedly connected with an installation slider 8. One end of the installation slider 8 is provided with an installation hole 81 for the guide rod 72 to be inserted. Through the installation slider 8 and the installation hole 81, the positioning rod 9 can slide and rotate on the guide rod 72. One end of the installation plate 4 is provided with a slot 42 for the positioning rod 9 to slide and be inserted. The slot 42 can better cooperate with the insertion of the positioning rod 9.

[0032] For the more stable positioning rod 9, one end of the guide rod 72 of the present application is fixedly connected with a limit block 73. The limit block 73 can limit the positioning rod 9 from sliding out of the guide rod 72. A rubber pad is fixedly connected to the side where the limit plate 5 contacts the fastening bolt 3. The rubber pad can form a certain protection for the fastening bolt 3.

[0033] A fault warning system for the main drive chain of a wind turbine unit includes any one of the above-mentioned protection components.

[0034] During actual implementation, first control the installation plate 4 and the limit plate 5 to slide away from the installation base 1. Then rotate the positioning rod 9 and slide the positioning rod 9 so that the positioning rod 9 can be directly inserted into the slot 42, thereby restricting the sliding of the installation plate 4. Then use the fastening bolt 3 to fix the installation base 1 and the sensor main body 2 on the equipment installation surface. After the fastening bolt 3 is fixed, slide the positioning rod 9 again so that the installation plate 4 is in a free state. At this time, the installation plate 4 will slide under the action of the spring 6, and the installation plate 4 will drive the limit plate 5 to slide together. After sliding, the limit plate 5 will hold the fastening bolt 3, preventing the fastening bolt 3 from rotating due to the vibration of the equipment, so that the installation base 1 and the sensor main body 2 are stably installed on the equipment.

[0035] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
