The purpose of this utility model is achieved through the following technical solutions:
The utility model air-conditioning system comprises the many groups heated air circulation pipeline that is installed in the engine room cover in the wind power generating set, and the top of every group of heated air circulation pipeline is a suction end, and the bottom is the outlet side of hot air; The bottom of described heated air circulation pipeline is towards the bottom of engine room cover.
Wherein: described heated air circulation pipeline comprises air-supply pipeline, electric heater, centrifugal blower and wind-distributing pipe road, the end of pipeline of wherein blowing is positioned at the top of engine room cover, this end is connected with electric heater and centrifugal blower in turn, the other end of air-supply pipeline is positioned at the bottom of engine room cover, and this end is connected with the wind-distributing pipe road; The inwall on described engine room cover top is respectively equipped with air filter and axial-flow blower, and engine room cover and axial-flow blower corresponding part have exhaust outlet, and the hot air in the engine room cover is discharged by exhaust outlet by axial-flow blower; The bottom of described engine room cover is provided with the air sucking mouth, and ambient air filters by the air sucking mouth and enters in the engine room cover; The inwall of described engine room cover is provided with thermal insulation layer; Described engine room cover sealing is installed on the tower tube, is sealedly connected with air guide sleeve on engine room cover, and runner sealing is arranged on the air guide sleeve.
Advantage of the present utility model and good effect are:
The utility model by centrifugal blower and electric heater from the air draught of engine room cover inner top, and hot blast delivered to the engine room cover bottom, air circulation in the engine room cover is flowed, and then make the air temperature in the engine room cover very even, ensured effectively in the engine room cover various device can be under suitable temperature reliably working.
2. axial-flow blower of the present utility model can drain into the high temperature air in the engine room cover in the ambient atmosphere environment, guarantees that the air quality in the engine room cover is good.
3. each parts of the utility model wind power generating set are tightly connected, and make reliable sealing in the engine room cover, reduce thermal losses and sand and dust and enter in the engine room cover.
4. air sucking mouth of the present utility model and exhaust outlet place all adopt air filter, thereby have guaranteed the cleanliness of air.
5. the utility model can make the interior equipment of engine room cover always work in the environment of suitable temperature and cleanliness.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Wherein: 1 is thermal insulation layer, and 2 are the air-supply pipeline, and 3 is electric heater, and 4 is centrifugal blower, and 5 is air filter, and 6 is axial-flow blower, and 7 is the air sucking mouth, and 8 is the wind-distributing pipe road, and 9 is seal ring, and 10 is engine room cover, and 11 is the tower tube, and 12 is air guide sleeve, and 13 is blade.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, low temperature wind-driven generator group of the present utility model comprises engine room cover 10, tower tube 11, air guide sleeve 12 and blade 13, engine room cover 10 is installed on the tower tube 11, on engine room cover 10, be connected with air guide sleeve 12, blade 13 is arranged on the air guide sleeve 12, between engine room cover 10 and the tower tube 11, between air guide sleeve 12 and the engine room cover 10 and be tightly connected by seal ring 9 respectively between blade 13 and the air guide sleeve 12.
Air-conditioning system of the present utility model comprises that many groups are installed in the heated air circulation pipeline (present embodiment is two groups) in the engine room cover 10, the top of every group of heated air circulation pipeline is a suction end, the bottom is the outlet side of hot air, and the bottom of heated air circulation pipeline is towards the bottom of engine room cover 10.Every group of heated air circulation pipeline includes air-supply pipeline 2, electric heater 3, centrifugal blower 4 and wind-distributing pipe road 8, the end of pipeline 2 of wherein blowing is positioned at the top of engine room cover 10, this end is connected with electric heater 3 and centrifugal blower 4 in turn, the other end of air-supply pipeline 2 is positioned at the bottom of engine room cover 10, and this end is connected with wind-distributing pipe road 8.The inwall on engine room cover 10 tops is respectively equipped with air filter 5 and axial-flow blower 6, and engine room cover 10 has exhaust outlet with axial-flow blower 6 corresponding parts, and the hot air in the engine room cover 10 is discharged by exhaust outlet by axial-flow blower 6.The bottom of engine room cover 10 is provided with air sucking mouth 7, and ambient air enters in the engine room cover 10 after filtering by air sucking mouth 7.The inwall of engine room cover 10 is provided with thermal insulation layer 1, and thermal insulation layer 1 can be PEF or polyurethane material.
Working principle of the present utility model is:
When temperature is low in engine room cover 10, centrifugal blower 4 is delivered to the engine room cover bottom after by supply air duct 2, wind-distributing pipe road 8 wind being heated up from the air draught of engine room cover top and by electric heater 5, hot blast is again to the upper reaches, thereby the air circulation in the engine room cover is flowed, and the temperature in the engine room cover keeps evenly.When summer, air temperature is higher in the engine room cover, axial-flow blower 6 air draught and hot air drained into outside the engine room cover in engine room cover; And extraneous air enters in the engine room cover after filter air sucking mouth 7.
