The invention discloses an integrated concentric water distributor for multi-layer water injection of an oil field, which has the following working principle: the device is moved to a required depth, water is poured into the sleeve 108, at this time, water in the sleeve 108 flows into the middle of the movable sealing tube 103 (at this time, elliptical holes formed in the movable sealing tube 103 and the fixed sealing tube 102 are staggered), then the pressure of water in the sleeve 108 is increased, at this time, a pressure cabin 201 arranged in the sleeve 108 is extruded, at this time, an extruding piston 208 moves downwards, a reset spring 209 is compressed (gas in the pressure cabin 201 is compressed), the extruding piston 208 moves while driving a linkage rod 210 to move, the linkage rod 210 moves to drive a rack rod 211 to move, the first half of the movement of the rack rod 211 does not drive a ratchet assembly 221 to rotate due to no tooth shape, the process drives two telescopic friction blocks 202 to expand outwards, so that the telescopic friction blocks 202 are propped against the inner wall of the sleeve 108, meanwhile, the pressure in the rotating cavity 203 changes along with the pressure change in the pressure cabin 201, and therefore the three telescopic clamping blocks 204 also stretch out of the adjusting ring 109. When pressure is continuously applied, the rack bar 211 continuously moves downwards, so that the tooth form on the rack bar 211 is in contact with the ratchet component 221, at this time, the ratchet component 221 rotates, the ratchet component 221 drives the half gear 219 to rotate through the gearbox 220, the half gear 219 rotates to drive the double-toothed plate 217 to do linear reciprocating movement (the half gear 219 always rotates, only the half gear 219 rotates 180 degrees), the double-toothed plate 217 moves to drive the matched rack 215 to move, the matched rack 215 moves to drive the matched gear 214 to rotate, the matched gear 214 rotates to drive the executing gear 216 to rotate, the executing gear 216 rotates to drive the side gear 213 to rotate, the side gear 213 rotates to drive the adjusting rotating frame 207 to rotate, the adjusting rotating frame 207 rotates to drive the rotating connecting ring 205 and the rotating cavity 203 to rotate, the rotating cavity 203 rotates to drive the telescopic clamping block 204 to rotate to drive the adjusting ring 109 to rotate, the adjusting ring 109 rotates to drive the moving seal pipe 103, at this time, the elliptical through holes formed on the fixed seal pipe 102 and the moving seal pipe 103 are overlapped, water in the moving seal pipe 103 flows outwards, then the water pressure is discharged through the circular ring 104, and the water pressure is ejected upwards, and the water pressure of the sealing sleeve 106 is ejected upwards, and the water pressure is overcome. When the elliptical through holes at the movable sealing tube 103 and the fixed sealing tube 102 need to be closed, that is, the elliptical through holes formed at the movable sealing tube 103 and the fixed sealing tube 102 are staggered, pressure needs to be applied to the water in the sleeve 108 again, the purpose of the pressure-retaining spring 106 is to keep the water pressure in the sleeve 108 to a minimum value (the pressure-retaining spring 209 can be compressed), at this time, the rack bar 211 moves downwards again (when the pressure in the sleeve 108 is reduced or the pressure is not applied to the water pressure in the sleeve 108, the pressure-retaining spring 209 can drive the extruding piston 208 to move upwards again, at this time, the rack bar 211 moves upwards, and because the ratchet assembly 221 is arranged, the rack bar 211 moves upwards and does not drive the input shaft of the gearbox 220 to rotate, so that the double-toothed plate 217 is motionless), the half gear 219 rotates, and the half gear 219 drives the double-toothed plate 217 to move towards the opposite direction, so that the movable sealing tube 103 rotates to the initial position. When the control part is not needed, the control part can be lifted out.
