Abstract

The utility model provides an equipment used for detecting boiler steam pipe state-a boiler steam pipe state detection and leakage alarm device. The utility model comprises that an acoustic wave sensor and an acoustic wave conducting tube as an integral installation is arranged on a pipe in parallel; the output and input terminals of the acoustic wave sensor are connected with the input and output terminals of the detection host machine; the output terminal of the detection host machine is connected with a display device; and the detection host machine and the display device are arranged on a cabinet. The utility model has the advantage of scientific structural design. The utility model adopts modern technique to check the state of boiler steam pipe, to display the virtual state of the boiler steam pipe, and to give an alarm towards the accident hidden danger. The users can give the utility model repair and maintenance in a planned and pointed way in order to ensure the regular and safe operation of the boiler steam pipe and avoid unnecessary economic loss. The device also has the advantages of using and repair convenience and low manufacture cost.

Description

Boiler steam pipe state-detection and leakage warning device
Technical field
The utility model relates to a kind of equipment that is used to detect the boiler steam pipe state---boiler steam pipe state-detection and leakage warning device.Belong to boiler steam pipe detection technique field.
Background technology
The equipment of existing detection boiler steam pipe state can only detect after boiler steam pipe takes place to leak or has abnormal conditions.Though can detect the reason that its accident takes place, the loss that it causes the scene can't remedy.
Summary of the invention
The purpose of this utility model is the defective at above-mentioned existence, a kind of boiler steam pipe state-detection and leakage warning device are proposed, detect the boiler steam pipe state, guarantee that the user accomplishes planned, maintenance targetedly to boiler steam pipe, can effectively block up the generation of cutting off and preventing accident.Technical solution of the present utility model: its structure is that the parallel integral installation of sonic sensor and sound wave conducting tube is on boiler tubing, the output of sonic sensor/go into termination detects the input of main frame/go out end, detect the input end of the output termination display device of main frame, detection main frame, display device are installed on the rack.Advantage of the present utility model: scientific structure design, adopt modern technologies to detect the boiler steam pipe state, show the virtual condition of boiler steam pipe intuitively, the hidden danger of accident is comprised that boiler steam pipe leaks report to the police.The user can be planned, targetedly boiler steam pipe is maintained, thereby guarantee the normal safe handling of boiler steam pipe, avoids unnecessary economic loss.It is easy to maintenance that this device also has use, characteristics such as low cost of manufacture.
Description of drawings
Accompanying drawing is an example structure synoptic diagram of the present utility model.
Among the figure 1 is sonic sensor (model can be used GTXL-3), the 2nd, sound wave conducting tube, the 3rd, and display device, the 4th detects main frame (model can be used 650VF-P42.8), the 5th, rack.
Embodiment
The contrast accompanying drawing, sonic sensor 1 walks abreast integral installations on boiler tubing with sound wave conducting tube 2, the output of sonic sensor 1/go into termination detects the input of main frame 4/go out end, detects the input end of the output termination display device 3 of main frame 4, detects main frame 4, display device 3 is installed on the rack 5.
The course of work: sonic sensor 1 and the 2 parallel integral installations of sound wave conducting tube are on boiler tubing, sonic sensor 1 is wherein surveyed the sound of boiler tubing timely, and convert voice signal to electric signal and flow to and detect main frame 4, carry out data processing by detecting main frame 4, and with sonic sensor 1 message exchange, main frame 4 The results of data processing send to display device 3 and show or report to the police after testing.
Along with the development of generation technology, modern electricity generation boiler has entered high capacity, high parameter epoch, and generator tube quantity is on the increase, and the reliability requirement that is in operation improves constantly.Safety, the economical operation that will directly influence genset in case take place to leak in generator tube.Therefore, generator tube leaks prevents and to the early detection of leaking with handle increasingly important to electricity power enterprise.
Boiler steam pipe state-detection and leakage warning device are to adopt acoustic measurement and signal processing technology, realize early prevention and leakage alarm that boiler steam pipe is leaked.Device is gathered voice signal in the stove by sonic sensor, machine carries out Fast Fourier Transform (FFT) (FFT) and spectrum analysis to signal as calculated, distinguish background signal and leakage signal, the trace analysis in case the seizure leakage signal will be delayed time, signal will send warning after reaching threshold value.

Claims (1)

1, boiler steam pipe state-detection and leakage warning device, it is characterized in that the parallel integral installation of sonic sensor (1) and sound wave conducting tube (2) is on boiler tubing, the output of sonic sensor (1)/go into termination detects the input of main frame (4)/go out end, detect the input end of the output termination display device (3) of main frame (4), detection main frame (4), display device (3) are installed on the rack (5).
