Abstract
The utility model discloses an automatic fire blocking door for a hearth flame monitor. A movable plate is provided with a hole, wherein a guide sleeve is fixed at the hole of the movable plate. An image transmission system comprises a camera protecting cover, wherein the camera protecting cover is arranged inside the guide sleeve in a penetrating mode. A fixed beam is fixed to the movable plate. Travel switches in pair are fixed to the fixed beam. The automatic fire blocking door further comprises an air cylinder and a baffle. The air cylinder is fixed to the movable plate. The guide sleeve is provided with an inserting groove which is perpendicular to the axial direction of the guide sleeve. The baffle is inserted in the inserting groove and fixed to the free end of a telescopic rod of the air cylinder. The automatic fire blocking door for the hearth flame monitor has the advantages of being simple in structure, stable in operation, and capable of being adapted to different installation states of the hearth flame monitor, and therefore the adaptability of the automatic fire blocking door is improved.
Description
Technical field
The utility model relates to the technical field of monitor, more particularly relates to the technical field of flame eye.
Background technology
Flame eye is mainly used in fire coal, fuel oil, gas fired-boiler, also be applicable to other kiln boiler of power plant of petroleum chemical enterprise's explosion-proof occasion of fuel-firing gas-firing stove requirement and various direct combustion fuels etc., be directly installed on furnace wall, monitor the fired state in burner hearth, be beneficial to operator and can directly see real flame image in burner hearth on the screen of controlling room monitor, understand and grasp in real time the combustion case in burner hearth, it also has automatic protection functions, it is the indispensable device of safe operation of the boiler, current flame eye adopts side-mounted mostly, it includes fixed head, portable plate, pilot sleeve, built-in beam, defeated picture system and paired travel switch, this portable plate is movably arranged on fixed head, on this portable plate and fixed head, offer respectively corresponding hole, pilot sleeve is fixed on the place, hole of portable plate, the defeated camera guard shield as system places in this pilot sleeve, built-in beam is fixed on portable plate for providing and drive and walking support as system to defeated, paired travel switch is fixed on built-in beam, for limiting the stroke of defeated picture system, at the hole place of fixed head, by loose-leaf system, be movably installed with fire-screen door for defeated while exiting as system, fire-screen door is automatically closed and is realized the fiery function of gear under the effect of gravity, but, when needs adopt flame eye when roof-mounted, at this moment fire-screen door just can not realize automatically and closing, thereby cannot implement to keep off fiery function, can damage pick-up lens so on the one hand, flame in stove and heat also can be scurried out voluntarily on the other hand, not only can bring potential safety hazard, and can cause a large amount of losses of heat.
Utility model content
The purpose of this utility model provides a kind of simple in structure in order to solve above-mentioned deficiency exactly, stable, in the dress situation of top, when flame eye exits, also can effectively stop the furnace flame monitor automatic catch vent that furnace flame is arbitrarily scurried out.
The technical solution that the utility model adopts in order to solve the problems of the technologies described above is as follows:
Furnace flame monitor automatic catch vent, it includes portable plate, pilot sleeve, built-in beam, defeated picture system and paired travel switch, on described portable plate, offer porose, pilot sleeve is fixed on the place, hole of portable plate, describedly defeatedly as system, include camera guard shield, this camera guard shield places in this pilot sleeve, built-in beam is fixed on portable plate, paired travel switch is fixed on built-in beam, it also includes cylinder and baffle plate, described cylinder is fixed on portable plate, on pilot sleeve, offer and its axial perpendicular slot, described baffle plate is plugged in this slot, this plate washer is fixed on the expansion link free end of cylinder.
Described cylinder also can be fixed on built-in beam.
The beneficial effect that the utility model adopts above-mentioned technical solution to reach is: simple in structure, adopt cylinder to drive on baffle plate and carry out Passive Control, when defeated picture system is touched travel switch, cylinder will drive baffle plate to open or close, stable, can adapt to the different installment state of flame eye, improve the applicability of product.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, furnace flame monitor automatic catch vent, it includes portable plate 1, pilot sleeve 2, built-in beam 3, defeated picture system 4, paired travel switch 5, cylinder 6 and baffle plate 7, on described portable plate 1, offer porose 8, pilot sleeve 2 is fixed on these 8 places, hole of portable plate 1, describedly defeatedly as system 4, include camera guard shield 9, this camera guard shield 9 is set in this pilot sleeve 2, built-in beam 3 is fixed on portable plate 1, paired travel switch 5 is fixed on built-in beam 3, described cylinder 6 is fixed on portable plate 1 or built-in beam 3, on pilot sleeve 2, offer and its axial perpendicular slot 10, described baffle plate 7 is plugged in this slot 10, this plate washer 7 is fixed on the expansion link free end of cylinder 6, during use, when defeated picture system 4 is touched to travel switch 5, cylinder 6 will drive baffle plate 7 to open or close, the function of flame is opened or is stopped in realization, simple in structure, operate stable, strong adaptability.Above-mentionedly defeatedly as system, belong to prior art, at this without detailed description.
