A wind power generator is an electric power device that converts wind energy into mechanical energy, and converts the mechanical energy into electric energy. In a broad sense, the heat energy utilization engine takes the sun as a heat source and takes the atmosphere as a working medium. Wind power generation utilizes natural energy. The power generation is much better than that of diesel oil. But is inferior to diesel generators if used in an emergency. Wind power generation is not considered as a backup power source, but can be used for a long time. The principle of wind power generation is that wind power drives windmill blades to rotate, and then the rotating speed is increased through a speed increaser, so that a generator is promoted to generate electricity. According to the current wind power generator technology, the power generation can be started at a breeze speed of about three meters per second. Wind power generation is forming a hot tide in the world because it has no fuel problems and does not produce radiation or air pollution.

However, a large amount of heat is generated during the operation of the wind turbine generator system, and if the heat generated by the wind turbine generator system cannot be dissipated in time, an electrical system in the wind turbine generator system is burnt out. In order to effectively dissipate heat of the wind generating set, a set of water cooling system is installed, and in order to increase the heat dissipation efficiency of the water cooling system, a set of high-power air blowers is usually arranged to help a radiator in the water cooling system to dissipate heat, but the air blowers can generate noise to influence the surrounding environment of the wind generating set to cause noise pollution.

When the LED illuminating lamp fixing device is used, firstly, the connecting rod can be directly rotated to enable the sliding block to rotate in the hollow frame, the connecting rod rotates in the sliding ball at the moment, the sliding ball can be driven to slide in the sliding groove along with the left and right movement of the sliding block in the hollow frame, the rotating plate can rotate along the hinged seat, the sucker can be adsorbed on the rod wall of the supporting rod, the fixing plate can be further fixed conveniently, when the rotating plate needs to be folded, the connecting rod can be rotated to enable the sliding block to move leftwards in the hollow frame, the connecting rod rotates in the sliding ball at the moment, the sliding ball slides downwards in the sliding groove, the rotating plate rotates clockwise along the hinged seat, when the LED illuminating lamp needs to be used, the fixing pin can be pulled out of the fixing block, the LED illuminating lamp can be pulled out outwards until the LED illuminating lamp slides out of the groove, at the moment, the sliding, at the moment, the fixing pin penetrates through the through hole in the fixing block to be inserted into the jack, and the power supply of the LED illuminating lamp is plugged and the LED illuminating lamp is turned on. So, this warning sign can conveniently expand and fix to can fix on the pole wall of bracing piece through the sucking disc, make fixed more firm, can not pushed down by wind or some maloperation. This warning sign is equipped with the LED light to the LED light conveniently expandes and packs up, expandes and lead to bumping bad condition when avoiding the light not need using daytime.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
