The utility model relates to a peep camera device in high temperature resistant preventing dust, including protective case and camera, protective case is the cover tubular structure outer tube and inner tube, both ends seal forms water cooling jacket between outer tube and the inner tube, and the inner tube tail end stretches out the outer tube, and the inner tube tail end seals, and the outer tube tail end is equipped with water inlet and delivery port, and the inner tube tail end is equipped with the air inlet, the camera includes image -pickup probe, fixture, data line, and image -pickup probe is cylindrical, and image -pickup probe passes through fixture and fixes the head end at the inner tube, is equipped with a plurality of air vents on the fixture, and image -pickup probe is connected to data line one end, and the other end is drawn from the inner tube tail end. The advantage is: it is simply portable, can develop the detection to different positions, through water -cooling and gaseous duplicate protection, the head end of having realized making a video recording is high temperature resistant and can realize preventing dust, improves the definition of making a video recording, realizes carrying on under the adverse circumstances of high temperature thickness dirt such as blast funnace hot blast stove and hot -air pipes the endoscopic type reconnaissance of making a video recording.

Description

Camera head is peeped in a kind of high temperature resistant dustproof

Technical field

This utility model relates to peeping in one camera head, particularly relates in a kind of high temperature resistant dustproof for blast funnace hot blast stove and hot air duct detection and peeps camera head.

Background technology

Blast funnace hot blast stove and hot air duct broadly fall into high-temperature closed container, and operator generally judges internal state indirectly only by temperature, pressure, changes in flow rate etc., and can not directly observe. although along with continuous technological progress, the lifting of capabilities of refractory materials, the improvement of design and operational approach, the life level of air stove is also improved, but in long-term running, still inevitably there is breakage in some positions, such as combustor gas well wall is damaged, vault and body of wall refractory brick come off, the refractory brick loose or dislocation etc. of hot air duct, at present when blast funnace hot blast stove and hot air duct find damaged, often have to wait until that the cool furnace rear of damping down could manually be reconnoitred, it is then determined that mending option, and cool stove is it is generally required to time a couple of days, cause that maintenance duration extends, have a strong impact on production. if air stove and hot air duct can be detected when not cool stove, then in time breakage can being judged, thus formulating mending option as early as possible, shortening maintenance duration.

Inside peeping camera shooting type prospecting is a kind of effective means getting information about internal tank situation in time, in some fields, such as medical, automobile, flight-line maintenance etc. obtain widely used, currently also there are some for peeping camera shooting type detecting device and method in Industrial Stoves, such as: a kind of on-line monitoring intelligent flame endoscope CN102288609A, high-temp. Kilm CN2276693 etc., but these device and methods generally all take to fixedly mount on furnace wall the mode of picture pick-up device, this kind of obvious monitored area of mode is limited, and motility is not enough; Although also having some installation methods such as Portable high-temperature inner observation mirror system CN202126534U, Portable high temperature endoscope CN104199183A etc. can realize the inspection at diverse location, but the said equipment does not possess dust reduction capability, air stove and hot air duct internal high temperature, many flue dust adverse circumstances in use and be restricted; There is also the deficiencies such as structure complexity, processing and operation inconvenience in addition with some other similar device method.

Summary of the invention

For overcoming the deficiencies in the prior art, the purpose of this utility model is to provide in a kind of high temperature resistant dustproof and peeps camera head, realize when not cool stove to peeping shooting prospecting in blast funnace hot blast stove and hot air duct, and intuitively can carry out the detection of different parts flexibly.

For achieving the above object, this utility model is achieved through the following technical solutions:

Camera head is peeped in a kind of high temperature resistant dustproof, including protection sleeve pipe and photographic head, protection sleeve pipe is sleeve-like configuration, including outer tube and interior pipe, between outer tube and interior pipe, two ends welded seal forms water collar, and interior pipe tail end stretches out outer tube, and interior pipe tail end is closed, outer tube tail end is provided with water inlet and outlet, and interior pipe tail end is provided with air inlet; Described photographic head includes camera probe, fixture, data wire, and camera probe is cylindrical, and camera probe is fixed on the head end of interior pipe by fixture, and fixture is provided with some passages, and data wire one end connects camera probe, and the other end is drawn from interior pipe tail end.

Camera probe is the camera probe of self illumination body.

It is provided with diversion rib plate between outer tube and interior pipe.

Compared with prior art, the beneficial effects of the utility model are:

Interior pipe leads to protective gas; outer tube logical cooling water; duplicate protection by water-cooled and gas; achieve shooting head end high temperature resistant and can realize dust-proof; improve shooting definition; thus realizing carrying out inner peeping type shooting prospecting under the adverse circumstances of the high temperature thickness dirt such as blast funnace hot blast stove and hot air duct, and this device is simply portable, can be flexible different parts is carried out detection.

Detailed description of the invention

Below in conjunction with Figure of description, this utility model is described in detail, it should be noted that enforcement of the present utility model is not limited to following embodiment.

See Fig. 1-Fig. 3, camera head is peeped in high temperature resistant dustproof, including protection sleeve pipe and photographic head, protection sleeve pipe is the sleeve-like configuration of stainless steel, its structure includes outer tube 2 and interior pipe 3, and between outer tube 2 and interior pipe 3, two ends welded seal forms water collar, and interior pipe 3 tail end stretches out outer tube 2, interior pipe 3 tail end is closed, and outer tube 2 tail end is provided with water inlet 4 and outlet 7; For being provided with diversion rib plate 10 between strengthening cooling outer tube 2 and interior pipe 3, make water collar between pipe be divided into two chambers, until head end just UNICOM, so first can be flowed into head end by tail end after forced cooling water entrance water collar, tail end is flowed back to again, it is ensured that the cooling effect of head end by head end; Interior pipe 3 is used for leading to protective gas, and interior pipe 3 tail end is provided with air inlet 5; Photographic head includes camera probe 1, fixture 8, data wire 6, camera probe 1 is cylindrical, and self illumination body, camera probe 1 is fixed on the head end of interior pipe 3 by fixture 8, fixture 8 is provided with some passages 9, is used for passing through protective gas, in order to form gas shield from the ejection of interior pipe 3 head end, protection camera probe 1, not by smoke contamination, also functions to certain cooling effect simultaneously; Fixture 8 is fixed by screw and interior pipe 3 head end; Data wire 6 is used for transmitting camera data, and data wire 6 one end connects camera probe 1, and the other end is drawn from interior pipe 3 tail end and is used for connecting camera data control, harvester.

During work; pass into industrial colling from water inlet 4, pass into compression air from air inlet 5, the duplicate protection of logical supercooled water and protective gas; camera probe 1 is played high temperature resistant and dust-proof effect, thus realize high temperature, many flue dust adverse circumstances under remain to the purpose of normal shooting prospecting.
