Abstract
The utility model discloses a kind of fan comprehensive performance detecting platforms, including an aeroperformance sensing chamber and a semi-anechoic room, the aeroperformance sensing chamber is connected with semi-anechoic room by a connection air hose, it is connected by a backwind tube between the air inlet and the top of semi-anechoic room of the aeroperformance sensing chamber, an accessory fan and an auxiliary air-valve is respectively equipped on the backwind tube.Use the fan comprehensive performance detecting platform of the utility model, by the way that aeroperformance sensing chamber and semi-anechoic room are integrated together, the noise specifications such as sound pressure level, acoustic power level are also tested together while carrying out aerodynamic performance detection, since various operating modes can be simulated when carrying out aeroperformance detection, so the noise specification measured more meets actual working conditions；Simultaneously as two tests are carried out at the same time, detection efficiency is also greatly improved, the disassembling operations of wind turbine are reduced.
Description
Technical field
The utility model is related to a kind of detection platform, particularly relate to it is a kind of to the aeroperformance of wind turbine, sound pressure level,
The multinomial technical indicator such as acoustic power level carries out the detection platform of synthesis measuring, belongs to mechanical test field.
Background technology
Before fan design pilot stage and the manufacture of finished product wind turbine, it is both needed to be detected the properties of wind turbine.Its
Main detection project generally includes the noise specifications such as the aeroperformances such as air quantity, wind pressure, wind speed and sound pressure level, acoustic power level, when
It further include so the detection of power etc..Existing detection platform, aeroperformance and noise specification need to respectively detect on two platforms,
When namely aeroperformance is tested, noise specification cannot be tested simultaneously, if test, and in unlimited occasion, by outer
The interference on boundary is very big, and the noise specification measured is inaccurate；When closed anechoic chamber or semi-anechoic room carry out noise specification test,
Since wind turbine does not load load, the indexs such as sound pressure level, acoustic power level for measuring are poor with environment of the wind turbine in actual motion
It is not larger, it can not accurately embody the true noise specification of wind turbine.
Utility model content
To overcome drawbacks described above, the utility model, which is intended to provide, a kind of can be carried out at the same time aeroperformance and noise specification carries out
It measures, and the fan comprehensive Testing Platform of actual working conditions can be simulated.
In order to achieve the above objectives, the technical solution adopted in the utility model is：A kind of fan comprehensive performance detecting platform, packet
An aeroperformance sensing chamber and a semi-anechoic room are included, the aeroperformance sensing chamber and semi-anechoic room pass through a connection wind
Pipe is connected, and is connected by a backwind tube between the air inlet and the top of semi-anechoic room of the aeroperformance sensing chamber,
An accessory fan and an auxiliary air-valve are respectively equipped on the backwind tube.
It is described connection air hose be located at semi-anechoic room end connection there are one adjustable connecting flange.
Two ends of the accessory fan and backwind tube are respectively equipped with silencing pot close to one end of semi-anechoic room.
The fan comprehensive performance detecting platform for using the utility model, by aeroperformance sensing chamber and semi-anechoic room
It is integrated together, the noise specifications such as sound pressure level, acoustic power level also one is gone forward side by side while carrying out aerodynamic performance detection
Row test, since various operating modes can be simulated when carrying out aeroperformance detection, so the noise specification measured more meets practical work
Condition condition；Simultaneously as two tests are carried out at the same time, detection efficiency is also greatly improved, the disassembling operations of wind turbine are reduced.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
In figure：1- aeroperformances sensing chamber, 2- semi-anechoic rooms, 3- connection air hoses, 4- backwind tubes, 5- accessory fans, 6- are auxiliary
Air-valve is helped, 7- is adjustable connecting flange, 8- silencing pots, 9- is tested wind turbine, 10- adjusting air valves.
Specific implementation mode
As shown in Figure 1, the utility model discloses a kind of fan comprehensive performance detecting platform, including an aeroperformance inspection
Room 1 and a semi-anechoic room 2 are surveyed, it is pneumatic to detect its air quantity, wind pressure, wind speed and its power etc. by aeroperformance sensing chamber
Performance can accurately detect the noise specifications such as sound pressure level, the acoustic power level of tested wind turbine 9 by semi-anechoic room.
The innovative point of comprehensive performance detection platform described in the utility model essentially consists in 1 He of aeroperformance sensing chamber
Semi-anechoic room 2 is connected by a connection air hose 3, the top of the air inlet and semi-anechoic room 2 of the aeroperformance sensing chamber 1
Between be connected by a backwind tube 4, an accessory fan 5 and an auxiliary air-valve 6 are respectively equipped on the backwind tube 4.
Embodiment：Tested wind turbine 9 is fixed to one end that connection air hose 3 is located at semi-anechoic room 2, i.e., tested wind turbine 9 is set
In in semi-anechoic room；First 10 standard-sized sheet of adjusting air valve being placed in aeroperformance sensing chamber 1, open accessory fan 5 and standard-sized sheet
Air-valve 6 is assisted, tested wind turbine 9 is then turned on, measures property indices and noise objective, recorded；Then it adjusts respectively
The opening angle for assisting air-valve 6 and adjusting air valve 10, simulates the field working conditions of several duct resistance, measures every working condition
Under performance indicator, and recorded.To obtain the comprehensive performance of the tested wind turbine 9.
Fan comprehensive performance detecting platform described in the utility model, innovative point also reside in the connection air hose 3 and are located at
There are one adjustable connecting flanges 7 for the end connection of semi-anechoic room 2.For the wind turbine of different model, diameter, only need to change corresponding
Adjustable connecting flange 7, so that it may tested wind turbine 9 is easily connected to connection air hose 3.
The fan comprehensive performance detecting platform of the utility model, another innovative point are the two of the accessory fan 5
End and backwind tube 4 are respectively equipped with silencing pot 8 close to one end of semi-anechoic room 2.By silencing pot 8, auxiliary is reduced to greatest extent
Influence of the noise to test when wind turbine 5 is run keeps semi-anechoic room 2 more acurrate to being tested the noise objective that wind turbine 9 is surveyed.
