The oil field boiler fire observation device of the embodiment of the present invention has innovative design below:
(1) flame monitoring architecture design: boiler flame monitoring device uses video camera to observe device, is seen by original
Fire hole position is observed, and the flame vision signal of acquisition, to emitter on the spot, passes through transmitter by wired or wireless transmissions
The duty room of wireless transmission.Camera is fixed on adjustable positioning bracket, and light filling is designed between camera and flame-observing hole can from heat dissipation
Flexible fire observation device connection.
(2) fire observation device designs
(2.1) multiple degrees of freedom focus fixing device designs: camera passes through flame monitoring frame and telescopic light filling from the dress that radiates
It sets, it is common to complete the design of multiple degrees of freedom fixed-focus.When horizontal direction rotates, vertical rotation shaft lock nut is unclamped, rotation is horizontally diverted
Handle can be completed.It is identical as horizontal adjustment when vertical adjustment.When front and back adjusts, horizontal concrete chute bottom lock nut is unclamped, it will
Camera carries out whole anterior-posterior translation.Pitch angle regulating device is designed in camera bottom, unclamps camera base adjusting screw, can
Complete the adjustment of camera pitch angle.
(2.2) light filling intensity adjustment designs: when outdoor light is relatively strong or by direct sunlight, being moved forward and backward outer layer retracting cylinder
Weakened close to camera with imaging procephalic light；It, can be by rotating outer layer retracting cylinder, contracting if cannot still meet the requirements
Small bottom heat release hole realizes the fine tuning of entering light intensity.When outdoor light is weaker, outer layer retracting cylinder can move backward so that this can
The space of light transmission is formed between flexible light filling self-heat irradiation device and flame-observing hole；Outer layer retracting cylinder can also be adjusted and internal layer is flexible
The registration of the aperture of cylinder is to adjust light transmission.
(2.3) convection current is from heat dissipation design: flame-observing hole device is monitored that operating temperature has centainly using common camera
It is required that.Former flame-observing hole position temperature is higher, has some impact on to cam lens and circuit board.Due to camera and former sight fire
Connected between hole by light filling self-heat irradiation device, thus the embodiment of the present invention the interior design of light filling self-heat irradiation device and be embedded in every
Hot glass is realized and is isolated between former flame-observing hole and camera.Meanwhile 15cm × 5cm aperture is processed in light filling radiator bottom；
And the side wall of outer layer retracting cylinder is equipped with the closed hot-fluid guide groove extended along 12 telescopic direction of outer layer retracting cylinder；It is mending
When light heat sink interior temperature is higher, inner air is wandering along hot-fluid guide groove after being heated, and bottom cold air is taken out from aperture
Inspiration enters, and lateral migration to surface of camera head realizes automatic dissipating heat function persistently to cool down to its surface.
(3) flame self-identifying designs
Hearth combustion flame front position plays a significant role in flame profile, combustion position decision process, oil field pot
Furnace needs strict control flame front in the process of running, it is ensured that flame front cannot wash away boiler tube and boiler tube card.Existing fire
Flame leading edge determination method is to cause observed result inaccurate by naked-eye observation.The embodiment of the present invention is monitored using video camera
After mode, flame front and boiler tube, boiler tube card position can be clearly shown in monitored picture.After having above-mentioned condition, record is utilized
As the mobile detection alert function of system, after video pictures resolution ratio determines, setting screen mobile detection alert point works as flame
After leading edge reaches set point, that is, think flame impingement boiler tube, flame self-recognition function is realized in the alarm of monitoring system buzzing at this time.
As shown in Figure 3 is the schematic diagram for the image that monitoring camera 2 is observed from flame-observing hole 5, can be clearly indicated out in figure
Inboard wall of burner hearth 101, boiler tube 102, flame front 103, alarm point 104；Wherein alarm point 104 is to preset in systems
, alarm point 104 has a safe distance apart from boiler tube 102；In the picture can with the position of extract real-time flame front 103,
And it alarms when flame front 103 reaches the position of alarm point 104.
Technological parameter requirement:
1, all material be stainless steel material, being capable of shatter-proof heatproof.
2, all devices are installed as whole removable.
3, each component installation and degree of regulation are less than ± 2cm.
Applicable elements of the invention: being suitable for oil field outdoor sports steam injection station boiler, have it is easy flexibly, be easily installed,
The many advantages such as easily operated, reliable operation, security risk be few.One kind is proposed in the embodiment of the present invention in construction requirement needs
Or in order to improve working efficiency in the case where, design light, simple and direct, multiple functional novel fire observation device, it is special to promote oil field
The reliability of industry equipment reduces worker's labor intensity, abatement security risk point, improves production efficiency.It passes through " ingenious knot
Structure, function be integrated and the layout of installation site " mode realizes simple and convenient reliable function.The key of the embodiment of the present invention exists
The perfect of " internal structure and function science " is gone up and in reliability, science, safety and mentality of designing.
The above is a preferred embodiment of the present invention, it is noted that for those skilled in the art
For, without departing from the principles of the present invention, it can also make several improvements and retouch, these improvements and modifications
