The steam generator secondary side wall combing vehicle in the nuclear power station comprises a vehicle body, a driving mechanism and cameras, wherein the vehicle body is flat, and a connector in plug-in connection with detection equipment is arranged on the front side wall of the vehicle body; the driving mechanism comprises permanent magnet driving wheels and a motor, the motor is hermetically arranged inside the vehicle body, the motor is connected with the permanent magnet driving wheels, and the permanent magnet driving wheels are positioned on the two sides of the bottom of the vehicle body, and extend out of the bottom of the vehicle body; the camera is provided with a light compensating lamp, the cameras are hermetically nested in the two side walls and the front side wall of the vehicle body; the permanent magnet driving wheels are matched with the motor, thereby achieving adsorption to the inner wall of the cylinder body and creeping along the inner wall, and solving the technical problems in a moving and hanging way of a two-free-degree combined motion, moreover, detection to the inner wall of the cylinder body can be accomplished by the carried detection equipment at a time.
Description
Technical field
The present invention relates to a kind of used in nuclear power station equipment, relate in particular to and a kind ofly for what creep on the cylinder inboard wall at nuclear power station steam generator secondary side, climb wall car.
Background technology
Used in nuclear power station steam generator is the connection hinge in nuclear power plant one, between secondary circuit, is also one of equipment that nuclear power plant et out of order in service is maximum; Wherein, steam generator is taken in the heat that nuclear reactor the produces agent that is cooled to, gets back to reactor and continue coolingly after steam generator cooling, and this is a loop; To steam generator, supply water, steam generator produces the work of Steam Actuation steam turbine, and cooling condensed water is got back to steam generator and continued to produce steam, and this circulation loop is called secondary circuit, take steam generator as boundary's cooling system conditioner enters a side loop of steam generator, is exactly primary side of steam generator; The steam generator of take produces a side loop of steam as boundary, be exactly steam generator secondary side.
The serviceability of steam generator and safe reliability are vital for the safe and stable operation of whole nuclear station.Because steam generator is worked for a long time, the cylinder inboard wall of steam generator secondary side, heat-transfer pipe there will be impurity, drift or slight crack etc., owing to being positioned at cylinder inboard wall, staff cannot observe directly from cylindrical shell, therefore need to cylinder inboard wall, heat-transfer pipe, detect by check implement, due to narrow space in cylindrical shell, therefore need to have and can carry the miniature compact car body that check implement moves in cylindrical shell, could comprehensively to steam generator secondary side, detect like this.
US Patent No. 20040131462A1 discloses a kind of " the small mechanical arm of maintenance steam generator inner tube ", this mechanical arm is to control and insert with a cylinder, extract expansion mechanism, and used the swelling action of cover air cylinder driven expansion mechanism therein, carrying aspect the car body that check implement moves in cylindrical shell, this mechanical arm is by one group of screw-nut body, to realize check implement to be unsettled translation in cylindrical shell, and utilize one group of two-way oil cylinder to realize the rotation of check implement, by translation and the aggregate motion that rotates these two degree of freedom, realize the movement of check implement in cylindrical shell, complete the detection to cylinder inboard wall, China Patent No. CN200910072832.3 discloses the car body that similarly makes check implement translation too, the fixed mount of existing these car bodies is to be all fixed on the manhole of steam generator by expansion mechanism, and then adopt the retractor devices such as cylinder or hydraulic efficiency manipulator that check implement is to unsettled being deep in cylindrical shell, to realize translation, because retractor device and check implement need enter in cylindrical shell by manhole, therefore size can not be too large, thereby the detection range behind each location is less, in the time of need detecting whole cylindrical shell, need carry out location for several times and just can complete, detection efficiency is lower, separately, adopt hydraulic pressure, pneumatic mixing to control, application is trouble comparatively, and pneumatic supply and hydraulic power source are provided, once and hydraulic efficiency pressure system leak, hydraulic oil will pollute steam generator, cause serious accidental pollution, potential safety hazard is larger, moreover, the unsettled detection mode of movement of this two degree of freedom (rotation and translation) aggregate motion, because motion path is limited, its check implement carrying is existed and detect blind area, due to unsettled, also make the cylinder inboard wall that approaches that its check implement carrying cannot closer distance, for tiny slight crack, impurity etc., there is undetected possibility, cause final detection effect inaccurate.
Therefore, need badly a kind of simple and compact for structure and can carry the nuclear power station steam generator secondary side that check implement carries out freely creeping at cylinder inboard wall and climb wall car.
Summary of the invention
