Note that the flow direction of the unidirectional intake pipe 10 is: only air is allowed to enter the pressing bag 9 from the one-way air inlet pipe 10, and the flow direction of the one-way air outlet pipe 11 is as follows: air is only allowed to flow from the bladder 9 into the annular air groove 7, so that air can be squeezed into the annular air groove 7 when the bladder 9 is pinched, and when the bladder 9 is released, the bladder 9 recovers from inflation and draws air into the bladder 9 along the one-way inlet pipe 10. So can make the lower extreme inflation of notes liquid pipe 4 to can with the firm cover of the hose 14 cover that awaits measuring establish outside notes liquid pipe 4, after having detected hose 14 lower part, open the control valve in the blast pipe 12 simultaneously, can emit the air in annular air duct 7, make notes liquid pipe 4 reduce and resume.
And then the hose 14 is taken down and turned around, and after the sleeved part of the hose 14 is shrunk and recovered, the other end of the hose 14 can be sleeved on the liquid injection pipe 4 again for detecting the other half part, so that various detection requirements are met.
A liquid return pipe 15 communicated with the interior of the detection cylinder 1 is arranged on the side wall of the detection cylinder 1, a recovery device for recovering the fluid in the detection cylinder 1 is arranged in the liquid return pipe 15, the recovery device comprises a piston 19 which is hermetically and slidably connected in the liquid return pipe 15, and the liquid return pipe 15 is embedded with a limit plug 17, the side wall of the piston 19 is provided with a one-way liquid outlet hole 20, the side wall of the limit plug 17 is provided with a one-way liquid inlet hole 18, concretely, the one-way liquid inlet hole 18 limits the one-way flow of the fluid from the right side to the left side of the limit plug 17, the one-way liquid outlet hole 20 also limits the one-way flow of the fluid from the right side to the left side of the piston 19, therefore, when the piston 19 moves to the left, the space between the liquid inlet pipe and the limiting plug 17 is increased to generate negative pressure, and the fluid is pumped into the liquid return pipe 15 through the one-way liquid inlet hole 18, when the piston 19 moves to the right, the pumped fluid can be extruded out along the one-way liquid outlet hole 20, and a one-way valve can be arranged in the hole during the specific manufacturing process.
The liquid return pipe 15 is internally provided with a driving mechanism for driving the piston 19 to move, the driving mechanism comprises a discharge coil 16 embedded in the liquid return pipe 15, the discharge coil 16 is electrically connected with the electrode plate 5 through a discharge circuit, and the piston 19 is made of a magnetic material. It should be noted that the connection and installation modes of the charging coil 8, the amplification control circuit, the discharging coil 16 and the discharging circuit all belong to the mature technology in the electrical field, and therefore, detailed descriptions are omitted. In addition, the discharge coil 16 adopts an inductance coil, so that the inductance coil can be connected with a parallel shift capacitor formed by the two electrode plates 5 to form an LC series connection, and an alternating current resonance pulse is generated, thereby continuously outputting an alternating current to the discharge coil 16.

After the measurement is finished, the electric charge stored in the electrode plate 5 can be transmitted to the discharge coil 16 by controlling the discharge circuit, and since the two electrode plates 5 form a parallel-bang capacitor, and will form an LC series with the discharge coil 16, therefore, alternating current can be discharged to the discharge coil 16, and the discharge coil 16 can generate an alternating magnetic field with a changing magnetic pole, so that the piston 19 made of magnetic material can move back and forth in the liquid return pipe 15, and as the charges on the electrode plate 5 are discharged through the discharging circuit, the electric field in the detection cylinder 1 is also disappeared, so the electrorheological fluid 13 in the detection cylinder 1 is changed back to liquid, when the piston 19 moves back and forth in the liquid return pipe 15, the electrorheological fluid 13 in the detection cylinder 1 can be continuously guided into a designated container along the liquid return pipe 15 for storage under the unidirectional flow limiting effect of the unidirectional liquid inlet hole 18 and the unidirectional liquid outlet hole 20.
In order to ensure that the whole hose 14 can be accurately detected, after the lower half part of the hose 14 is detected, the hose 14 can be turned around and sleeved on the liquid injection pipe 4 again, and the operations are repeated in sequence, so that the pipe diameters of all parts of the whole hose 14 can be detected, and various detection requirements can be met.
