A turning disc is arranged on the fixed disk. A track is provided between the turning disk and the fixed disk. Balls are provided in the track. The turning disk and the fixed disk are provided with chambers. A driving shaft is fixed on the turning disk; the impeller is fixed on top of the driving shaft and the turning is permanently connected with a turning support, which is provided with a bracket at bottom. A generator is fixed on the bracket. A transmission gear is provided between the driving shaft and the generator. The turning disk and the turning support are arranged so that the generator and the booster mechanism can be arranged at bottom of the tower. The utility model is simple in structure, reduces cost, is very easy to be repaired and maintained, lowers gravity center of the tower, increases safety. A wind scooper is provided on top of the tower so that the impeller can be automatically regulated with the wind, usable. Accordingly, the utility model is valuable in promotion and wide application.

Description

A kind of wind generating unit

Technical field

The utility model relates to a kind of power generating equipment, specifically, relates to a kind of wind generating unit.

Background technique

Wind energy is as a kind of green regenerating energy, utilization ratio in China is not high, and wind energy is very abundant in the storage level of China, the potentiality that can develop are very big, wind-driven generator as a kind of be that the device of electric energy has good development prospect with wind energy transformation, big at present, the technology comparative maturity of medium-sized wind-driven generator, but because the cost height is not suitable for general family and installs, use, small-sized wind power generator uses more extensive, but its speeder, generator generally is placed in cat head, poor stability is along with the increase of pylon height, higher to the reliability requirement of each parts, cause manufacture cost to strengthen, and install, maintenance, maintenance is inconvenient.

Summary of the invention

Goal of the invention of the present utility model be to provide a kind of simple in structure, cost is low, good stability, maintain wind generating unit easily.

To achieve these goals, the utility model is realized by the following technical solutions: a kind of wind generating unit, comprise pylon, described pylon is provided with impeller, it is characterized in that: the top of described pylon is provided with fixed tray, be provided with rolling disc above the described fixed tray, be provided with track between described rolling disc and the fixed tray, be provided with ball in the described track, described rolling disc, fixed tray has cavity, be set with driving shaft on the described rolling disc, described impeller is fixed on the end of driving shaft, and described rolling disc is fixedly connected with swinging mounting, and the lower end of described swinging mounting is provided with carriage, be fixed with generator on the described carriage, be provided with transmission device between described driving shaft and the generator.

Below be the further improvement of technical solutions of the utility model:

Described transmission device comprises the driving wheel that is fixed on the driving shaft, is arranged on the follower on the carriage, and described follower and driving wheel are in transmission connection, and described follower and generator are in transmission connection.

Be provided with speed increasing mechanism between described follower and the generator, described speed increasing mechanism comprise first belt wheel that is arranged on the carriage, second belt wheel that is connected with the first belt wheel belt, with coaxial the 3rd belt wheel that is connected of second belt wheel, described the 3rd belt wheel is connected with the belt wheel belt that is fixed on the generator rotor shafts end, and described first belt wheel is connected with follower is coaxial.

Be set with wind scooper on the described rolling disc.

Be provided with transition wheel between described follower and the driving wheel, described transition wheel and driving wheel are in transmission connection, and described transition wheel and follower are in transmission connection.

Beneficial effect: the utility model has adopted such scheme, the setting of rolling disc and swinging mounting makes generator, speed increasing mechanism can be arranged on the bottom of pylon, and is relatively simple for structure, reduced cost, maintain very conveniently, reduced the center of gravity of pylon, increased Security, the setting of tower top wind scooper, but the impeller box haul is adjusted automatically, easy to use, the utlity model has higher promotional value.
