Abstract
The invention discloses a lens adapter for a single-lens reflex camera. The lens adapter for the single-lens reflex camera comprises a lens barrel body, a primary lens hole and a secondary lens hole are formed in two ends of the lens barrel body respectively, a connecting thread is formed on the inner wall of each of the primary lens hole and the secondary lens hole, a slip-resistant thread layer is engraved on the middle surface of the lens barrel body, and lenses are arranged inside the primary lens hole and the secondary lens hole. By the means, the lens adapter for the single-lens reflex camera is simple in structure, one end of the lens adapter can be connected with a lens of the single-lens reflex camera while the other end of the lens adapter can be connected with a blast furnace detecting instrument, and after combination, work conditions inside a blast furnace can be observed by the single-lens reflex camera clearly by the aid of a high-definition imaging function of the single-lens reflex camera.
Description
Technical field
The present invention relates to camera lens field, particularly relate to a kind of lens adapter for slr camera.
Background technology
The basic reason of coking be ash deposition under molten state on heating surface, adjust with injection angle of burners, burning, boiler plant leaks out relevant.Fusion point of ash is the key of coking.Coking meeting causes that overheating steam temperature raises, and causes overheating steam temperature, reheat steam temperature desuperheating water to be opened greatly, even can cause the explosion of carbonated drink pipe; Coking meeting reduces boiler output, when serious, cause and is forced to blowing out; The serviceable life of boiler plant is shortened in coking meeting; Flue gas loss increases, and boiler efficiency reduces; Induced draft fan consumes power increases; Because coking is inhomogeneous often, thereby water-cooling wall slagging scorification meeting brings adverse effect to the thermal deviation of the water-flow circulation safety of natural circulation boiler and forced circulation boiler water-cooling wall.
Coking easily becomes lime-ash bulk, makes dragveyer, slag crusher transportation difficulty, and overload trip, makes slag runner blocking when serious sometimes, the load down operation of having to.When if coking fuses into bulk, because gravity falls from top, cause smashing furnace hopper water-cooling wall.Underload can cause that unstable combustion is even flame-out because falling large lump coke.If while causing the whole coking of water-cooling wall, only have blowing out to carry out artificial coke cleaning.
So operating personnel sometimes need to observe in time the working condition in stove, generalized case can adopt visual inspection, but so not only easily injured, is also not easy to observe clear; Single-lens reflex camera in our life is all generally for taking landscape or personage at ordinary times, if the function of slr camera high definition imaging is applied in kiln field, effect can have greatly improved.
Summary of the invention
The technical matters that the present invention mainly solves is to provide a kind of lens adapter for slr camera, simple in structure, one end can be connected with the camera lens of slr camera, the other end can be connected with blast furnace detection instrument, after combination, can observe by slr camera the working condition of high furnace interior, utilize the function of slr camera high-resolution imaging, can clearly observe the working condition in blast furnace.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of lens adapter for slr camera is provided, comprise lens barrel main body, the two ends of described lens barrel main body are respectively equipped with primary mirror hole and secondary mirror hole, the inwall in described primary mirror hole and secondary mirror hole is provided with connecting thread, the middle part surface of described lens barrel main body is carved with antiskid thread layer, and described primary mirror hole and inside, secondary mirror hole are provided with eyeglass.
In a preferred embodiment of the present invention, the material of described lens barrel main body is stainless steel.
In a preferred embodiment of the present invention, the surface of described lens barrel main body scribbles corrosion protection paint.
In a preferred embodiment of the present invention, the diameter of described lens barrel main body middle-end and the diameter of two side ends are not reciprocity.
The invention has the beneficial effects as follows: a kind of lens adapter for slr camera of the present invention, simple in structure, one end can be connected with the camera lens of slr camera, the other end can be connected with blast furnace detection instrument, after combination, can observe by slr camera the working condition of high furnace interior, utilize the function of slr camera high-resolution imaging, can clearly observe the working condition in blast furnace.
