Wherein, the heat-protecting glass that will be separated before and after inner cavity is equipped in the inner cavity of the light filling self-heat irradiation device 1.
Wherein, the vertical rotation shaft 3 is stainless steel tube, and the vertical rotation shaft 3 is inside and outside two layers of sleeve structure to realize It is scalable along vertical direction.Wherein described horizontal guide rail is channel steel, and the fluting equipped with 5cm wide is led with being formed in the middle part of channel steel Rail;Wherein described monitoring camera 2 includes pedestal and the camera being set on the base, and the pedestal has can controlled pitching turn Dynamic swivel head, the camera are fixed on the swivel head.Can realize in this way the horizontally rotating around vertical axes of camera, Vertical direction stretches, horizontal direction is stretched, the pitching of camera.
The oil field boiler fire observation device of the embodiment of the present invention has following innovative design:
(1) flame monitoring architecture design:Boiler flame monitoring device uses video camera to be seen to observe device 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 stent, 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 is by flame monitoring frame and telescopic light filling from the dress that radiates It puts, 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 with horizontal adjustment during vertical adjustment.During front and rear adjustment, 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, it is moved forward and backward outer layer retracting cylinder Weakened close to camera with imaging procephalic light;If cannot still meet the requirements, it can be contracted by rotating outer layer retracting cylinder Small bottom heat emission hole is realized finely tunes into luminous 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 stretches The registration of the trepanning 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, and cam lens and circuit board are had some impact on.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 it is embedded every Hot glass is realized and is isolated between former flame-observing hole and camera.Meanwhile process 15cm × 5cm trepannings 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 scatters after being heated along hot-fluid guide groove, and bottom cold air is taken out from trepanning Inspiration enters, and lateral migration to surface of camera head realizes automatic dissipating heat function persistently to be cooled down to its surface.
(3) flame self-identifying designs
Hearth combustion flame front position plays an important roll in flame profile, combustion position decision process, oil field pot Stove needs strictly to 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 by naked-eye observation, causes observed result inaccurate.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. It is the schematic diagram for the image that monitoring camera 2 is observed from flame-observing hole 5 as shown in Figure 3, 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 pre-set in systems , there are one safe distances apart from boiler tube 102 for alarm point 104;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:
1st, all material be stainless steel, being capable of shatter-proof heatproof.
2nd, all devices are installed as whole removable.
3rd, each component installation and degree of regulation are less than ± 2cm.
The applicable elements of the present invention: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 of, it is special to promote oil field for light, simple and direct, the multiple functional novel fire observation device of design The reliability of industry equipment reduces worker's labor intensity, abatement security risk point, improves production efficiency.It passes through " ingenious knot Structure, function integrate 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 the 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, several improvements and modifications can also be made, these improvements and modifications It should be regarded as protection scope of the present invention.
