Further, the monitoring device includes one kind or more of pressure gauge, flowmeter, airspeedometer, thermometer and hygrometer
Kind.
It further, further include platform, platform is arranged by wind collection, and ladder is provided below in platform.
The utility model has the advantages that compared with prior art.
1. the utility model can be energy saving, meet the requirement of national industrial policies and energy-saving and emission-reduction.
2. the diffuser exit wind flow in the utility model, wind speed, kinetic energy are relatively stable, wind-power electricity generation is effectively reduced
Machine machine catch air blade design size and material requirement, generate power for their own use, invest it is small, quick.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the schematic diagram that diffuser exit sprays jet stream in the utility model.
In figure, 1- returnairshaft, 2- collecting cover, 3- air duct, 4- ventilation motor, 5- diffuser, 6- sound attenuator, 7- monitoring dress
It sets, 8- wind-driven generator, 9- wind collection, 10- retention tower, 11- platform, 12- ladder.
Specific embodiment
The utility model is described further with reference to the accompanying drawing.
As shown in Figure 1, kinetic-energy power generator more than a kind of mine ventilation, including returnairshaft 1, collecting cover 2, air duct 3 and ventilation
Motor 4, collecting cover 2 are connected with the air outlet of returnairshaft 1, and air duct 3 is connected with the outlet of collecting cover 2, and ventilation motor 4 is arranged
It further include diffuser 5, sound attenuator 6, monitoring device 7, wind-driven generator 8, wind collection 9 and retention tower 10, diffusion in air duct 3
The entrance of device 5 is connected with air duct 3, and the outlet of diffuser 5 is connected with sound attenuator 6, sound attenuator 5 sequentially with 10 sum aggregate of retention tower
Air duct 9 is connected, and the exit of wind collection 9 is arranged in wind-driven generator 8, and monitoring device 7 is arranged in wind collection 9.Monitoring dress
Setting 7 includes the one or more of pressure gauge, flowmeter, airspeedometer, thermometer and hygrometer, is carried out to the air-flow in wind collection 9
Detection, influences the normal production needs of mine to guarantee wind-power electricity generation not.Retention tower 10 has bending section, bent angle 90
Degree.The outlet diameter of diffuser 5 is greater than inlet diameter.
After ventilating gas is sprayed with certain 10 Outlet Section of speed self-diffusion tower, unsteady flow conveying is adjusted through wind collection 8, is driven
Dynamic wind-driven generator 8 generates electricity.When 10 Outlet Section of retention tower changes at a distance from wind-driven generator 8, gas with
The continuous change of spray distance retention tower 10 need to be exported first and divulged information preferably to export remaining kinetic energy using retention tower 10
The flow behavior of gas is understood and is analyzed.
As shown in Fig. 2, being transported by spraying the gas jet flowing in ambient enviroment to the outlet of ventilating gas self-diffusion tower 10
Dynamic basic condition and specificity analysis, when air-flow flows in space, with the continuous increase of spray distance, Gas Jet is because of rapids
It flows lateral panting action to exchange with the medium of surrounding progress momentum and the continuous of quality, makes the cross-sectional area and mass flow of jet stream
It changes, constantly becomes larger, field of flow becomes cone-shaped, in the certain feelings of 10 Outlet Section diameter of retention tower and initial velocity
Under condition, spray distance is bigger, and air velocity declines faster, and velocity amplitude changes, and the dynamic of impeller is passed in the unit time
Energy value changes, and the performance number of wind-driven generator 8 also changes.
Under actual conditions, wind-driven generator 8 is set at a certain distance from retention tower 10 exports, in ventilation process, wind-engaging
Power generator 8 influences, the stagnation pressure formed before wind-driven generator 8 can normal ventilation operation characteristic to ventilation motor 4 it is bent
Line generates certain influence, and the optimum value for the distance value L that wind-driven generator 8 and retention tower 10 export is not change ventilation
Kinetic energy more than diffuser exit is drawn to the greatest extent under the premise of the normal ventilation operation characteristic curve of motor 4, and experimental study, which is learnt, works as
The d(d of distance L >=5 is ventilation blower outlet diameter) when, fan efficiency is identical as efficiency characteristic value when clear.Cause
This, when it is implemented, the outlet of retention tower 10 and the distance of wind-driven generator 8 should be greater than the outlet of the retention tower 10 equal to five times
Diameter.
To make full use of retention tower 10 to export remaining kinetic energy, installation wind collection 9 is exported in retention tower 10, encryption packing bolt is tight
It is solidly connected, in the case where guaranteeing that the former normal ventilation operation characteristic curve of ventilation blower is constant, maximal efficiency is gone out using retention tower 10
Kinetic energy power generation more than mouthful.
When it is implemented, the present apparatus further includes platform 11, platform 11 is arranged by wind collection 9, and platform 11 is provided below
Ladder 12.Operation of ascending a height is carried out convenient for operation and maintenance personal.
The embodiments of the utility model have been described in detail above with reference to the accompanying drawings, but the utility model is not limited to
Embodiment is stated, within the knowledge of a person skilled in the art, the utility model aims can also not departed from
Under the premise of various changes can be made.
