Abstract
The utility model relates to a video recording apparatus for the partial drainage of turbid water, which relates to a video recorder for detecting the surface quality of the underwater engineering structure in the turbid water and is composed of a video recorder (1), an illuminating lamp (2), a water drainage cover (3) and an underwater peeking apparatus (4), wherein, the illuminating lamp (2) is fixed in the water drainage cover (3) which is connected with the pick-up head (1-1) of the video recorder (1), and the underwater peeking apparatus (4) is tightly contacted with the monitor (1-2) of the video recorder (1). The video recording apparatus for the partial drainage of turbid water of the utility model is suitable for being used for the detection and the video recording of the underwater engineering of any low-visibility water areas and is adaptable to the underwater detection and video recording of the depth between the water surface and the underwater 100 meters, with the advantages of simple structure, convenient use and clear video recording picture, and is convenient to peek underwater video recording positions.
Description
Technical field:
The utility model relates to a kind of recording apparatus that muddy water detects Underwater Engineering body structure surface quality that is used for.
Background technology:
In engineerings such as offshore oil, harbour construction, reservoir construction, maintenance of the vessel, usually adopt to record a video under water submerged structure is detected, so that get rid of hidden danger.But this testing can only be carried out in having the waters of certain visibility.Because the performance difference of video recording equipment is also different to the requirement of operation waters visibility under water.The video tape recorder under water of better performances also requires underwater visibility greater than 100mm.The video recording picture is very unintelligible under this visibility conditions.Yet the visibility in present great river, great river and estuary waters thereof is all very low, almost nil.Existing video tape recorder under water can't detect video recording to submerged structure in this blind waters.
The utility model content:
The purpose of this utility model provides the recording apparatus of local draining in a kind of muddy water, and recording apparatus has simple in structure, and is easy to use, is applicable to any blind waters, and the video recording picture is clear, under water the good characteristics of depth flexibility.Recording apparatus of the present utility model is by video tape recorder 1, illuminating lamp 2, drainage cover 3, peeker 4 is formed under water; Illuminating lamp 2 is fixed in the drainage cover 3, and drainage cover 3 is connected with the camera 1-1 of video tape recorder 1, and peeker 4 closely contacts with the monitor 1-2 of video tape recorder 1 under water.Drainage cover 3 is made up of cover body 3-1, flexible gasket 3-2, sealing gasket flange 3-3, air inlet pipe 3-4, adapter sleeve 3-5; Flexible gasket 3-2 is fixed on the front end of sealing gasket flange 3-3, and the rear end of sealing gasket flange 3-3 is threaded with the front end of cover body 3-1, and the front end of adapter sleeve 3-5 is threaded with the rear end of cover body 3-1, is interlinked to the outside in air inlet pipe 3-4 and the drainage cover 3.Peeker 4 is made up of flexible and transparent bag 4-1, bellows 4-2, adpting flange 4-3, colourless transparent liquid 4-4 under water; Adpting flange 4-3 is fixed on the rear end of bellows 4-2, and flexible and transparent bag 4-1 is fixed in the bellows 4-2, and the length of flexible and transparent bag 4-1 is filled colourless transparent liquid 4-4 greater than the length of bellows 4-2 in the flexible and transparent bag 4-1.The recording apparatus of local draining is applicable to that any blind waters carries out the detection video recording of Underwater Engineering in the muddy water of the present utility model, can adapt to from the water surface to 100 meters dark degree of depth under water and detect video recording under water, have simple in structure, easy to use, be convenient to spy on the position of recording a video under water, the video recording picture is advantage clearly.
Description of drawings:
Fig. 1 is the overall structure schematic diagram of the utility model recording apparatus, and Fig. 2 is the structural representation of drainage cover 3 and illuminating lamp 2 in the recording apparatus, and Fig. 3 is the structural representation of peeker 4 under water in the recording apparatus.
Embodiment:
(referring to the present embodiment of Fig. 1-Fig. 3) by video tape recorder 1, illuminating lamp 2, drainage cover 3, peeker 4 is formed under water; Illuminating lamp 2 is fixed in the drainage cover 3, and drainage cover 3 is connected with the camera 1-1 of video tape recorder 1, and peeker 4 closely contacts with the monitor 1-2 of video tape recorder 1 under water.Drainage cover 3 is made up of cover body 3-1, flexible gasket 3-2, sealing gasket flange 3-3, air inlet pipe 3-4, adapter sleeve 3-5; Flexible gasket 3-2 is fixed on the front end of sealing gasket flange 3-3, and the rear end of sealing gasket flange 3-3 is threaded with the front end of cover body 3-1, and the front end of adapter sleeve 3-5 is threaded with the rear end of cover body 3-1, is interlinked to the outside in air inlet pipe 3-4 and the drainage cover 3.Peeker 4 is made up of flexible and transparent bag 4-1, bellows 4-2, adpting flange 4-3, colourless transparent liquid 4-4 under water; Adpting flange 4-3 is fixed on the rear end of bellows 4-2, and flexible and transparent bag 4-1 is fixed in the bellows 4-2, and the length of flexible and transparent bag 4-1 is filled colourless transparent liquid 4-4 greater than the length of bellows 4-2 in the flexible and transparent bag 4-1.Described colourless transparent liquid 4-4 is clear water or alcohol.Described air inlet pipe 3-4 is annular setting in drainage cover 3, has distribution of gas hole 3-6 on the air inlet pipe 3-4.
Operation principle: flexible gasket 3-1 of the present utility model can adapt to plane and the bigger curved surface surface to be checked of radian, is salient angle or little arc surface if detect the position, flexible gasket 3-1 can be made into corresponding concave surface; If tested surface is little concave panel, flexible gasket 3-1 can be made into corresponding convex surface.When dispensing gas in drainage cover 3, the water in the drainage cover 3 can be extruded from the small gap between flexible gasket 3-1 and the measured surface.Fill clear water or alcohol in the flexible and transparent bag 4-1 of peeker 4 under water, the pressure that can adapt to deep water, the two ends of flexible and transparent bag 4-1 closely contact with monitor and diver's helmet face-port respectively, can squeeze the muddy water in the visual field totally, bellows 4-2 has certain retractility, can make diver's conversion angle of peeker 4 under water, convenient observation videoed the picture at position, improves the quality that detects video recording.
