[0002] In recent years, my country's new energy installed capacity has continued to grow rapidly, and the proportion of new energy installed capacity in the power grid has been increasing. Conventional energy units at the sending and receiving ends have been replaced in large numbers. The power electronic characteristics of new energy have caused significant changes in the operation of the power grid. The new energy power stations that have been put into operation generally do not have primary frequency regulation functions, and only use AGC (automatic generation control) as a technical means of frequency regulation. The control and regulation cycle is relatively long, and it cannot respond quickly and effectively to frequency changes in the power grid, which brings many challenges to the safe operation of the power grid.

[0003] In the existing primary frequency control device of a wind farm, because the device contains numerous electronic components and circuits, these electronic components will consume electrical energy and convert it into heat energy when performing operations such as data processing, signal transmission, and power control. If the heat cannot be dissipated in a timely and effective manner, the temperature inside the device will continue to rise. High temperature will not only affect the performance and reliability of the electronic components and shorten their lifespan, but may also cause failures or even damage the equipment.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0031] During installation, first use bolts to install the installation component 2 to the place where it needs to be installed, then push the device body 1 to move in the direction of the installation component 2, and then the device body 1 and the installation component 2 are mutually engaged, so as to limit the installation of the device body 1. When the electronic components inside the device body 1 need to dissipate heat, first drive the two heat dissipation components 4 to rotate at the same time, and then one end of the heat dissipation component 4 is rotated, and then suction is generated at the end of the heat dissipation component 4 close to the device body 1, and then the hot air in the device body 1 is drawn to the outside through the air outlet 3. At the same time, the heat dissipation component 4 will drive the moving component 5 fixedly installed at one end to move back and forth repeatedly on the air outlet 3, and then the moving component 5 will drive the meshing several air guide components 6 to rotate repeatedly on the air outlet 3, so as to change the heat dissipation component 4 to extract hot air in different directions in the device body 1.

[0032] Thus, by driving the two heat dissipation components 4 to rotate at the same time, the heat dissipation components 4 will then draw the hot air in the device body 1 to the outside.

Then the mounting plate 201 drives several second clips 202 fixed thereon to move, and then the second clips 202 will be mutually engaged with the first clips 102. Then, the shell 101 can be limited and fixed, thereby improving the convenience of installation of the device body 1 and increasing the efficiency of installation.

[0038] When it is necessary to dissipate heat for the electronic components in the housing 101, the two dual-axis motors 401 are first driven to rotate at the same time, and then the dual-axis motors 401 drive the output shaft 402 fixedly installed at the output end to rotate, and the output shaft 402 drives the fixedly installed cooling fan 403 to rotate, so that the cooling fan 403 generates suction force close to one end of the housing 101, and then the hot air in the housing 101 is sucked to the outside through the air outlet 3.

[0039] In one embodiment, for the above-mentioned moving component 5, the moving component 5 includes a driving shaft 501, the other end of the driving shaft 501 is fixedly mounted on the output end of the dual-axis motor 401, one end of the driving shaft 501 is fixedly mounted with a rotating disk 502, and the other end of the rotating disk 502 is fixedly mounted with a rotating shaft 503.

A sliding groove 505 is opened on the air outlet 3 to be slidably installed with the sliding rod 504, and a gear bar 506 is fixedly installed on the top of the sliding rod 504.

At the same time, the rotating rod 601 drives the fixedly installed air guide plate 602 to rotate, and then the several air guide plates 602 will rotate repeatedly at the same time, thereby continuously changing the heat dissipation fan 403 to extract hot air in different directions, effectively avoiding the influence of the high temperature in the shell 101 on the performance and reliability of electronic components.
