Technical Field
The utility model relates to a camera device for examining water supply pipe is applicable to the structural defect of inspection municipal water supply pipe.
Background
In the operation process of the municipal water supply pipeline, pipeline damage or poor joint connection can cause pipeline leakage and influence the normal use of the water supply pipeline. At present, the inspection method of the municipal water supply pipeline generally adopts a pipeline robot to carry a high-definition camera unit for inspection or a pipeline periscope for inspection, but the inspection length is very limited, generally not more than 300m, and the inspection method cannot be used for inspection of a long water supply pipeline, and the diameter of the municipal water supply pipeline is usually small, so that the pipeline robot cannot enter the inspection; when the pipeline has sharp bends, siphons and the like, the pipeline robot and the pipeline periscope cannot perform inspection.
SUMMERY OF THE UTILITY MODEL
The utility model aims at: the utility model provides a camera device for inspecting water supply pipe to solve the problem that long water supply pipe or minor diameter water supply pipe can't be inspected, include the inspection to sharp bend, siphon pipeline. Therefore, the utility model adopts the following technical scheme:
the camera device for inspecting water supply pipeline is characterized by that its outer shell is made into transparent ball, and contains lighting source and several camera units.
The transparent ball is a ball body at least with a transparent lens part and a transparent illumination part, and is generally transparent as a whole.
For the transparent ball, the diameter of the transparent ball is selected according to the inner diameter (size) of the drainage pipeline and the hidden culvert and the predicted passable space in the pipeline, if the inner diameter of the pipeline is larger and the passable space in the pipeline is larger, the transparent ball with the larger diameter is selected, otherwise, the transparent ball with the smaller diameter is selected; the diameter of the transparent ball is generally selected according to the minimum inner diameter of the water supply pipeline, and the diameter of the transparent ball is about 10cm smaller than the minimum inner diameter of the water supply pipeline.
The size of the transparent ball also needs to consider the required buoyancy force, and the buoyancy force needs to just offset the weight of the ball body and the camera unit, the battery, the light source lamp and the like in the ball body. For this reason, a weight may need to be provided in the ball. The weight arrangement needs to take into account the balance of weight so that the center of gravity of the transparent ball camera is as centered as possible on the ball.
Preferably, the camera device is in the form of a "zero-buoyancy" or near "zero-buoyancy" sphere having an overall specific gravity equal to or slightly lower or slightly higher than that of water and a center of gravity at or near the center of the sphere. The 'zero-buoyancy' sphere is realized by properly configuring, weighting, losing weight or changing the diameter of the transparent sphere, so that the transparent sphere does not sink to the bottom or float to the top as far as possible in the pipeline, and can more freely and smoothly pass through a water supply pipeline, and each camera shooting unit can conveniently and uniformly shoot images.
The camera device is a panoramic camera device. Preferably, the panoramic camera device is provided with 6 camera units, and a space panoramic camera structure is formed by mutually orthogonal images. The camera shooting unit is as close to the spherical surface as possible, the focal length of the camera shooting unit is adjusted according to the radius of the transparent ball and the interval of the radius plus 10cm, and the camera shooting pipe wall images can be shot without missing in the rotation process of the transparent ball. The number of the camera units can be increased or decreased according to the parameters of the lens and the thickness of the pipeline.
Each camera shooting unit is required to be radially and uniformly distributed relative to the center of the sphere of the transparent ball, so that panoramic shooting is convenient to form on one hand, and the center of gravity of the camera shooting device is convenient to adjust and is positioned at the center of the sphere on the other hand.
The camera unit can adopt a camera. The camera unit can be provided with a detachable or non-detachable storage medium besides the optical structure and the control circuit board.
The lighting source can adopt a low-voltage L ED ultra-bright lamp strip, and a power supply in the camera device can adopt a lithium battery to supply power to the lighting source and the camera equipment.
L ED lamp area can encircle at camera device periphery for external illumination is basically even, does not have the illumination dead angle, confirm camera unit, battery and lamp area equipment and can normally work after, can beat the foamed glue in the spheroid, fill the space with the foamed glue, fix a position camera unit etc. electron component simultaneously for the spheroid is at the pipeline in-process camera unit can not rock, improves the spheroid resistance to destruction ability simultaneously.
The transparent ball of the utility model adopts thin wall, high transparency and non-breakable material (such as acrylic, etc.), and is composed of two hemispheres, and a connecting groove is arranged between the two hemispheres for convenient bonding; the two hemispheres are bonded and sealed by glue, a transparent adhesive tape is wound for 2-3 circles along the connecting seam, and the position of the camera shooting unit is avoided from being over against the seam.
The camera shooting unit and the lamp strip are assembled and can be started after normal work, and the camera shooting and illuminating device needs to be started before the transparent ball is sealed because the sealed ball cannot be operated any more, and the camera shooting and illuminating device can be started before use if remote control equipment is adopted.
Inside filling and fixed transparent ball with the foamed cement, the purpose is to guarantee that camera device is fixed in the spheroid for the spheroid pipeline operation in-process camera unit can not remove, improves the spheroid resistance to destruction simultaneously.
The camera device, the battery and the lamp strip are assembled and can be started after normal work, and the camera device and the illuminating device are started before the transparent ball is sealed because the sealed ball cannot be operated any more, and can be started again before use if remote control equipment is adopted.
The defect position judgment can roughly determine the position of the defect according to the start time, the end time and the length of the pipeline recorded in the pipeline because the water flow speeds in the water supply pipes are basically the same.
The utility model discloses an inner wall image of water supply pipe is shot with video-corder in succession, the inside quality of inspection water supply pipe, including the inspection of sharp bend pipeline, siphon pipeline, judge the type, scope and the severity of pipe wall defect to roughly confirm the position of defect, solved municipal water supply pipe inspection difficult problem, the method is simple, convenient, economy, high-efficient, and also be applicable to other pipeline and the culvert pipe that are used for carrying clean water, all can inspect when full pipe and non-full pipe.
