Specific embodiments

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0028] Please refer to Figures 1-8 As shown, the present utility model is a double-fed air-cooled converter platform for display, including a first partition platform, a second partition platform is installed on one side of the first partition platform, a third partition platform is installed at one end of one side of the second partition platform, and a fourth partition platform is installed at the other end of the side of the second partition platform close to the third partition platform;

[0029] A circuit breaker and a contactor are provided on the first partition platform, a control unit, a soft start unit, a power distribution unit, and a filter capacitor unit are provided on the second partition platform, a power unit module is provided on the third partition platform, and a chopper module, a DO / DT reactor, an RC filter unit, a discharge resistor, and three groups of high-power fans are provided on the fourth partition platform;

[0030] After the device assembly on the above-mentioned first partition platform is completed, it can be used as a grid-connected platform. After the device assembly on the second partition platform is completed, it can be used as a control platform. After the device assembly on the third partition platform and the fourth partition platform is completed, they can be used as power platforms, so that the functionality of the platform can be further determined, which is convenient for the staff to perform maintenance or demonstrate to new employees, and is convenient for new employees to quickly master the operation;

[0031] Universal wheels are installed at the bottoms of the first partition platform, the second partition platform, the third partition platform, and the fourth partition platform. The universal wheels adopt existing products with a locking structure, so that the staff can move the device through the universal wheels, and at the same time, the universal wheels can be locked after the movement is completed, initially ensuring the stability of the device;

[0032] A friction mechanism for stabilizing itself is provided on the second partition platform. The friction mechanism includes an installation bin, the installation bin is installed on the inner side wall of the second partition platform, screw rods are uniformly arranged at the bottom inside the installation bin, worm wheels are installed on the outer sides of the screw rods near the top, a movable plate is sleeved on the outer sides of the screw rods, and the movable plate penetrates through the installation bin. An installation plate is installed at the bottom of the movable plate, and a rubber friction plate is installed at the bottom of the installation plate;

[0033] The movable plate is slidably connected to the installation bin, and the movable plate is threadedly connected to the screw rod;

[0034] The screw rod and the installation bin are connected by a bearing, so that when the screw rod rotates, the corresponding movable plate thereon can drive the installation plate and the rubber friction plate to move up and down correspondingly;

[0035] The friction mechanism further includes an operating shaft, the operating shaft penetrates through both ends of the installation bin, and worms are uniformly installed on the outer side of the operating shaft;

[0036] The central axis of the worm coincides with the central axis of the operating shaft, and the worm is meshed with the worm wheel. The inclination angle of the spiral part on the worm can be set. When the worm rotates, it can drive the worm wheel to rotate, but the rotation of the worm wheel cannot drive the worm to rotate, thereby ensuring the stability of the screw rod during subsequent use;

[0037] The above-mentioned operating shaft is connected to the installation bin through a damping bearing, so that after the movement is completed, the staff can rotate the operating shaft forward. Through the meshing connection of the worm and the corresponding worm wheel, the movable plate can drive the mounting plate and the rubber friction plate thereon to move downward until they are fully fitted and pressed against the ground, thereby greatly increasing the friction between the device and the ground, and then ensuring its stability during subsequent use, and avoiding the situation of easy deviation due to insufficient friction of the universal wheels.

[0038] Working principle of the present utility model: Connect the device to the wind power system for use. When the device needs to be moved, as described above, unlock the universal wheels and rotate the operating shaft in the reverse direction, so that the movable plate drives the mounting plate and the rubber friction plate thereon to leave the ground. Then move the device to the designated position through the universal wheels;

[0039] After the movement is completed, re-lock the universal wheels and rotate the operating shaft forward. As described above, at this time, the movable plate drives the mounting plate and the rubber friction plate thereon to move downward until the rubber friction plate is fully fitted and pressed against the ground, so as to ensure the stability of the device during subsequent use.

[0040] The above has described an embodiment of the present utility model in detail, but the content described is only the preferred embodiment of the present utility model and cannot be considered as used to limit the scope of implementation of the present utility model. All equal changes and improvements made according to the scope of the application of the present utility model should still fall within the scope covered by the patent of the present utility model.
