Description
Technical Field
[0001] The utility model relates to the technical field of wind power generation auxiliary equipment, in particular to a protective shell structure of a wind power generator transmission box. Background Art
[0002] The working principle of a wind turbine is relatively simple. The wind rotor rotates under the action of wind, which converts the kinetic energy of the wind into mechanical energy of the wind rotor shaft. The generator rotates and generates electricity under the drive of the wind rotor shaft. In a broad sense, wind energy is also solar energy, so it can also be said that a wind turbine is a heat energy generator that uses the sun as a heat source and the atmosphere as a working medium.
[0003] The device that converts wind energy into electrical energy is installed in a cabin at high altitude. When the wind turbine is damaged, workers need to use various tools to dismantle the cabin shell at high altitude and inspect the internal devices. On the one hand, high-altitude work is highly dangerous and unsafe to operate. On the other hand, the disassembled casing is easy to fall, which may cause safety hazards. Utility Model Content

[0022] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.
[0023] See also Figure 1-3 A wind turbine transmission box protective shell structure includes a base 1, on which two wide side panels 11 and two long side panels 12 are fixedly connected, the two wide side panels 11 and the two long side panels 12 form a placement space for equipment installation, and the base 1 is slidably connected with a middle sliding cover 3 and two side sliding covers 2, respectively, the middle sliding cover 3 and the two side sliding covers 2 are both U-shaped, and the middle sliding cover 3 is slidably connected with the two side sliding covers 2 respectively; it also includes four locking mechanisms, which are symmetrically arranged and used to lock the two side sliding covers 2 on the long side panels 12.
[0024] By setting up two sliding side covers 2 and a middle cover 3, during maintenance, it is only necessary to unlock the locking mechanism and then slide the corresponding covers to display the internal devices, which is convenient for high-altitude maintenance. The side cover 2 can be moved to its opposite side to display more space for placing internal equipment. In addition, there is no need to take fixing measures to prevent the disassembled casing from falling, which is more conducive to high-altitude operations.
[0025] Furthermore, the locking mechanism includes a first rotating rod 4 rotatably connected to a groove on the long side plate 12, a first inclined block 41 is fixedly provided at the end of the first rotating rod 4, a support block 42 for supporting the first rotating rod 4 to maintain horizontality is fixedly provided on the long side plate 12, a second fixed rod 43 corresponding to the first rotating rod 4 is fixedly provided on the side sliding cover 2, and the second fixed rod 43 is provided with a second inclined block 44 corresponding to the first inclined block 41.
[0026] The side sliding cover 2 moves toward the corresponding wide side plate 11 to drive the second fixing rod 43 to move, and the second inclined block 44 on the second fixing rod 43 abuts against the first inclined block 41, so that the first rotating rod 4 rotates. When the second inclined block 44 is disengaged from the first inclined block 41, the first rotating rod 4 maintains a horizontal state under the action of gravity and the support of the support block 42.

[0028] The unlocking rod 5 is rotated, and the unlocking rod 5 moves downward to abut against the third rotating rod 45. The unlocking rod 5 continues to move, so that the third rotating rod 45 drives the first rotating rod 4 to move, so that the first inclined block 41 moves accordingly, and the first inclined block 41 releases the lock on the second inclined block 44. The utility model can realize tool-free installation and disassembly, which is more convenient for high-altitude operations.
