Abstract
The utility model relates to a large-sized wind-driven generator unit engine casing with an internal air deflector and airflow passages. The large-sized wind-driven generator unit engine casing comprises an engine casing body (1), an airflow inlet passage (2), a four-section airflow deflector (3) and an airflow outlet passage (4) are mounted inside the engine casing, a shutter (5) is mounted at the tail of the engine casing body (1), and a rear spoiler (6) is mounted on the rear top cover. The airflow inlet passage (2) is mounted on the lower portion of a front cover of the engine casing, the airflow outlet passage (4) is connected with the rear spoiler (6), a fan is disposed in the rear spoiler (6) to exhaust forcedly, the shutter (5) sucks air naturally, and the airflow inlet passage (2), the four-section type airflow deflector (3) and the airflow outlet passage (4) are connected flexibly. As the fan arranged in the rear spoiler can suck air forcedly by aids of the airflow deflector and the airflow passages arranged in the engine casing, airflow in the engine casing can be in circulation with the external according to the designed flow direction to dissipate heat in the engine.
Description
Technical field
The utility model relates to a kind of engine room cover of Large-scale Wind Turbines, and especially power is in the engine room cover of the above wind power generating set of 2MW.Belong to technical field of wind power generator.
Background technique
The proper functioning of the bearing rotation of Large-scale Wind Turbines inside, brake system, gear-box, generator and unsteady flow cabinet all can produce higher temperature rise, and each parts connection of present engine room cover body closely, and sealing is better.For the engine room cover internal heat is discharged the cabin, MW class wind turbine group in the past, a kind of is provided with ventilated port at engine room cover top or bottom, and this kind mode is subjected to real-time Influences on Wind Velocity, and the engine room cover inner air flows to fixingly, and radiating effect is very poor; Though a kind ofly established ventilated port and exhaust port in nacelle top and bottom, because inside is not provided with rational air-flow path, air-flow has just carried out local exchange in the engine room cover, and radiating effect is also not satisfactory.
The model utility content
The utility model purpose is, provide a kind of can make the engine room cover inner air according to design flow to carrying out regular flow, and, reach the Large-scale Wind Turbines engine room cover of desirable temperature drop effect out of my cabin by structures such as air-flow guide plate, air-flow paths with the discharge of the hot air in the engine room cover.
The purpose of this utility model is achieved in that inside has the Large-scale Wind Turbines engine room cover of air-flow guide plate and air-flow path, comprise the engine room cover body, described engine room cover body afterbody is equipped with venetian blind, air-flow guide plate, air flow inlet passage and flow outlet passage are installed in the engine room cover top, are provided with fan in the back spoiler of afterbody.It is characterized in that overhead guard and back overhead guard were installed before described air-flow guide plate, air flow inlet passage and flow outlet passage were close to; Air-flow guide plate and air flow inlet passage, flow outlet interchannel are flexible coupling; The air flow inlet passage is provided with air guide hole; The flow outlet passage is connected with the back spoiler; Described air flow inlet passage, air-flow guide plate and flow outlet passage are in one section air channel of the inner formation of engine room cover.
Its working principle is, forces air draught by the fan that is built in the spoiler of back, by inner air-flow guide plate and the air-flow path that is provided with of engine room cover, air-flow in the engine room cover flowed to the external world by shown design circulate, and takes away heat in the cabin.And the venetian blind that is arranged on the engine room cover afterbody replenishes extraneous fresh air in the engine room cover, to play the effect of changing the wind heat radiation.
Owing to utilize technique scheme, the utility model engine room cover radiating effect is excellent.

Embodiment
Followingly the utility model is described with reference to accompanying drawing.
Fig. 1 is the utility model engine room cover structural drawing, and as shown in Figure 1, the inside that the utility model relates to has the Large-scale Wind Turbines engine room cover of air-flow guide plate and air-flow path, comprises engine room cover body 1; Be installed in the venetian blind 5 of described engine room cover body 1 afterbody; Be installed in the air flow inlet passage 2 of engine room cover body 1 preceding overhead guard bottom; Be connected the air-flow guide plate 3 on the air flow inlet passage 2 with being flexible coupling; Be installed in overhead guard bottom, engine room cover body 1 back, be connected the flow outlet passage 4 on the air-flow guide plate 3 with being flexible coupling; Be connected the back spoiler 6 on the flow outlet passage 4.Connect air flow inlet passage 2, air-flow guide plate 3, flow outlet passage 4, formed an air-flow path from front to back on engine room cover top.
Force air draught by the fan that is built in the back spoiler 6, air-flow path by the inner air flow inlet passage 2 that is provided with of engine room cover, air- flow guide plate 3,4 formation of flow outlet passage, air-flow in the engine room cover flows to extraneous by shown design, takes away heat in the cabin.And the venetian blind 5 that is arranged on the engine room cover afterbody replenishes extraneous fresh air in the engine room cover, to play the effect of changing the wind heat radiation.
Fig. 2 is the utility model air flow inlet channel design figure, and as shown in Figure 2, described air flow inlet passage is provided with air guide hole 7.Hot air flow in the cabin imports to air flow inlet passage 2 by described air guide hole 7.
Fig. 3 is the utility model air-flow guide plate structure figure, and as shown in Figure 3, gas-flow deflector 3 is four segment structures, and the hot air flow that enters from air flow inlet passage 2 flows into flow outlet passage 4 by gas-flow deflector 3.
Fig. 4 is the utility model flow outlet channel design figure, as shown in Figure 4, flow outlet passage 4 is connected with back spoiler 6 by flange, after the hot air flow in the cabin imports to air flow inlet passage 2 by described air guide hole 7, discharges by gas-flow deflector 3 and flow outlet passage 4.
