Plate, the ultrasonic transducer are installed on cover plate.
Waveguide pipe provided by the utility model is a rigid, wall thickness 5mm, and the stainless steel cylinder of inner wall smooth is interior
Footpath is more than ultrasonic transducer diameter.
Further, multiple expiration pilot micropores are offered on the cover plate.Due to waveguide pipe relative closure, also certain
Being disturbed to " virtual height " caused by ultrasonic transducer for aqueous vapor is prevented in degree.
Further, the waveguide pipe bottom sidewall is welded with being fixed on the inclined plane of top cover introversion sloping bottom；It is described to lead
It is connected at the top of wave duct by flange bolt with top cover.The waveguide pipe side wall is extended with two relative boss, and the top cover is provided with
Support corresponding with two boss, the boss are connected with corresponding support by flange bolt respectively.The structure design can avoid
Ultrasonic transducer produces resonance in connection waveguide pipe.
Further, the guided wave bottom of the tube is fixedly connected with two support frames being oppositely arranged, and support frame as described above is fixed
On inclined base.The support frame can support waveguide pipe to ensure that its is vertical.
Further, the circular isolation kickboard to be fluctuated with liquid level in top cover is provided with the waveguide pipe.The circle
The diameter of isolation kickboard is slightly less than guided wave bore.Circular isolation kickboard is set in waveguide pipe, strengthens effective echo reflection, together
Shi Youxiao eliminates the absorption interference of liquid level foam.
Further, the guided wave bottom of the tube is fixed with kickboard support, the kickboard support by toroidal frame be fixedly connected
Right-angled intersection frame composition on toroidal frame, the toroidal frame are fixedly connected on the bottom opening of waveguide pipe, support frame as described above top
Portion is fixedly connected on toroidal frame.
Kickboard support is set in guided wave bottom of the tube, avoids the circular isolation kickboard hair fastener in low water level.
The beneficial effects of the utility model：Level measuring fills in this turbine-generator units top cover provided by the utility model
Put, it is simple in construction, it is easy to operate, solve the problems, such as to exist using ultrasonic sensor that error is big and easy saltus step so that super
Acoustic measurement is accurate, reliable.

Embodiment
With reference to the accompanying drawings and detailed description, the utility model is furtherd elucidate.
Embodiment：
Level measurement device in a kind of turbine-generator units top cover is present embodiments provided, refering to Fig. 1-3, top, 8 inner bottom parts
Provided with inclined base 9, top is provided with fixed station, and the level measurement device includes the waveguide pipe 1 being fixedly arranged on vertically in top cover, led
Wave duct 1 is a rigid, wall thickness 5mm, inner wall smooth and upper and lower opening stainless steel cylinder, and internal diameter is more than ultrasonic transducer
2 diameters.
