Abstract
The utility model discloses an air speed governing air supplier which comprises a frame, a shield fixed on the frame, and a fan arranged at one end of the shield, wherein a hanging hole is arranged in the top of the shield; and an air speed sensor is hung through the hanging hole; moreover, the air speed sensor is arranged in the shield. The stable air flow provided by the air speed governing air supplier guarantees small air speed fluctuation on the same sections of certain points in the shield, and improves the stability of an air speed governing sensor; the air flow values of each point on the air flow direction in the shield are changed regularly; therefore, the air speed sensor is guaranteed to have higher precision during governing; the air speed of a whole ventilation system is effectively and timely monitored and governed; the safety and the stability of an underground ventilation system are improved; moreover, the air speed governing air supplier is convenient to operate, and saves time and efforts.
Description
Technical field:
The utility model relates to a kind of air velocity transducer adjustment equipment, relates in particular to a kind of distinguished and admirable, wind speed carries out adjustment to air velocity transducer wind speed adjustment air feed machine of simulating in the mine ventilation system.
Background technique:
In order to guarantee the safe operation of mine ventilation system, the air velocity transducer important electrical part that is absolutely necessary, air velocity transducer need carry out adjustment before being installed in the down-hole, present adjusting process is also fairly simple, wind regime adopts electric drier or other blower fan, and therefore, always there is distinguished and admirable instability in the wind speed adjustment, disturb greatly the situation that wind speed is fluctuated.The data that the air velocity transducer that adjustment goes out is in use provided accurately with stable, cause the fluctuated of wind speed control system inadequately.
The model utility content:
Exist the low problem of precision in order to solve the air velocity transducer adjustment, the purpose of this utility model provide a kind of can the simulation underworkings carry out the air velocity transducer adjustment with the precision that improves air velocity transducer, guarantee that air velocity transducer accurately provides the data of tunnel wind speed, in time monitors and adjust the wind speed of ventilation system, the safety of raising down-hole ventilation system and the wind speed adjustment air feed machine of stability when using in the down-hole.
The technical solution of the utility model realizes in the following manner:
A kind of wind speed adjustment air feed machine, it comprises frame, be fixed on guard shield on the frame, be positioned at the fan of guard shield one end, wherein, hangs the hole on the guard shield top, hangs an air velocity transducer by hanging the hole, air velocity transducer is positioned at guard shield.
The distinguished and admirable outlet of blower fan is aimed in air velocity transducer whirlpool body inlet side.
Fan is an ac fan.
Ac fan is four and evenly is arranged in the guard shield air intake.
Good effect of the present utility model is:
1, this wind speed adjustment air feed machine provides stablizes and has distinguished and admirablely guaranteed that certain fluctuations in wind speed of putting on the same section is little in the guard shield, has improved the stability of adjustment air velocity transducer; Every the regular variation of distinguished and admirable value on the wind direction has higher precision in the guard shield when having guaranteed the air velocity transducer adjustment, effectively, in time monitors and adjust the wind speed of ventilation system, the safety and the stability of raising down-hole ventilation system.
2, easy to operate, time saving and energy saving.Air velocity transducer is hung in hanging the hole, plugs aviation plug, makes air velocity transducer and substation, divides station owner's communication port to link to each other with upper-position unit, starts wind speed adjustment air feed machine, and can the adjustment wind speed by remote control.
Description of drawings:
Fig. 1 is a structural principle schematic representation of the present utility model.
Embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
As seen from Figure 1: a kind of wind speed adjustment air feed machine, it comprises frame 5, be fixed on guard shield 1 on the frame, be positioned at the fan 4 of guard shield one end, wherein, hangs hole 3 on the guard shield top, hang an air velocity transducer 2 by hanging the hole, air velocity transducer 2 is positioned at guard shield.
Be it can also be seen that by Fig. 1: the distinguished and admirable outlet of blower fan is aimed in air velocity transducer whirlpool body inlet side.
Be it can also be seen that by Fig. 1: fan 4 is ac fan 4.
Be it can also be seen that by Fig. 1: ac fan 4 is four and evenly is arranged in the guard shield air intake.
Working procedure of the present utility model and using method:
Air velocity transducer is hung in guard shield by hanging the hole, made air velocity transducer whirlpool body inlet side aim at the distinguished and admirable outlet of blower fan; Aviation plug is inserted sensor and be connected with the KJ90 substation; Cooperate remotely-controlled operation and utilize substation and upper-position unit between communication realize the adjustment of air velocity transducer, each air velocity transducer can uninterrupted for a long time adjustment.
