Abstract
The utility model relates to an underwater oscillation center sensor, consisting of a sensor sealing shell (1), a top cover sealing ring (2), an underwater cable (3), an opposite-type optical couple (4), a light barrier (5), a transmission rod sealing component (6), a transmission rod sealing end cover (7), a transmission rod (8), a sensor sealing shell top cap (9) and a cable sealing component (10). Wherein, the opposite-type optical couple (4) is arranged in the sensor sealing shell (1). The power line and the signal output line of the opposite-type optical couple are connected with the underwater cable (3). The underwater cable (3) runs through the sensor sealing shell (1) by the cable sealing component (10). The transmission rod (8) penetrates through the transmission rod sealing component (6) and the transmission rod sealing end cover (7) and is fixed with the light barrier (5). The utility model detects and locates the oscillation center position of an underwater automatic welding platform swing mechanism by using the information of the mutual alignment between the opposite-type optical couple and the light barrier. The utility model has the advantages of simple structure, stable work and simple use, maintenance and repair.
Description
Technical field
The utility model relates to a kind of underwater swaying-centre sensor that is used to the oscillation center of swing mechanism setting under water, the detection of swing mechanism center of oscillation position and location underwater swaying-centre sensor under water in welding automatically especially under water.
Background technology
Nuclear power station radioactivity container is numerous, for example reactor pressure vessel, evaporimeter, voltage-stablizer, condenser, spentnuclear fuel pond, refuelling pool, water feeder etc.The radioactivity container is easy to generate corrosion cracking, the surface abrasion of serious threat power plant safety operation because of effect such as nuclear radiation stress, need carry out the REPAIR WELDING of forms such as the welding of leak source benefit plate, the repair welding of crackle bevel, erosion corrosion surface overlaying.In order to reduce maintenance cost and radiation effect, be welded in the water and carry out.Though adopted robot among other many nuclear power generating equipment maintenances, ripe practical underwater remote-control welding system does not occur as yet, all be at present to wear thick and heavy professional protective clothes by the diving welder to carry out manual welding.Diving welder manual welding, be directly exposed among the radiation environment, and because the power station can not accept up to 500,000 dollars cooling shutdown expense per hour, the internal tank water temperature that has is very high, operating environment is extremely abominable, welder's activity duration is no more than 1 hour usually, and the water surface also needs personnel control's suffered dose of radiation of welder etc. of diving under water in addition, thereby human input is with high costs.Adopt underwater remote-control welding system to carry out the maintenance of radioactivity container, can greatly reduce personnel's radiation cost and shutdown cost, significant for the nuclear power maintenance.Carry out underwater remote-control solder technology research and development, normal automatic welding platform under hydraulic drive water welds experiment, and underwater swaying-centre sensor can carry out the detection and the location of center of oscillation position to the swing mechanism of automatic welding platform under water.
Summary of the invention
According to background technology, the purpose of this utility model is to provide a kind of and is made up of sensor capsul, top seal circle, submerged cable, correlation light lotus root, shadow shield, drive link black box, drive link end cover, drive link, sensor capsul top cover and cable sealing assembly, correlation light lotus root and shadow shield are set in the sensor capsul, utilize mutual position information between them, as shadow shield just cover correlation light or just make correlation light by the time judge think reach oscillation center be used to measure the sensor of swing mechanism oscillation center under water.
To achieve these goals, the utility model is achieved through the following technical solutions:
A kind of underwater swaying-centre sensor, mainly by sensor capsul (1), top seal circle (2), submerged cable (3), correlation light lotus root (4), shadow shield (5), drive link black box (6), drive link end cover (7), drive link (8) sensor capsul top cover (9) and cable sealing assembly (10) are formed, wherein: correlation light lotus root (4) is arranged in the sensor capsul (1), the power line of correlation light lotus root links to each other with submerged cable (3) with output line, submerged cable (3) passes sensor capsul (1) by cable sealing assembly (10), pour into fluid sealant between submerged cable (3) and the cable sealing assembly (10), drive link (8) passes drive link black box (6) and transmission seal end cap (7) is fixed together with shadow shield (5), between drive link end cover (7) and the drive link black box (6), between cable sealing assembly (10) and the sensor capsul (1), between drive link black box (6) and the sensor capsul (1) " O " RunddichtringO is installed all, the open circumferential of sensor capsul (1) is provided with top seal circle (2), is inter-connected via a bolt joint between sensor capsul top cover (9) and the sensor capsul (1).
Owing to adopted the technique scheme part, the utlity model has following advantage and effect:
1, the utility model whole sensor adopts hermetically sealed design, can be in the 15m depth of water with interior use.
2, the core detecting element of the utility model sensor is a correlation light lotus root.
3, the utility model is handled the break-make of correlation light as the signal by center of oscillation, and positioning accuracy is higher.
