By the rotation of the guide pin 7 in the guide groove 13 along the circumferential direction of the central shaft 3, the guide ring 5, the upper housing 6, the connecting nipple 8, the lower housing 10 and the lower joint 12 are realized to rotate along the circumferential direction of the central shaft 3. The sand washing tool on the lower joint 12 is driven to rotate, and when flushing fluid is pumped in, the sand washing tool rotates to realize rotary spraying of the sand washing tool so as to wash sand and impurities at the bottom of the well. By repeating the operation of the hydraulic reversing mechanism, the flushing operation with large displacement can be realized. The guide groove 13 is provided with a circle in the circumferential direction of the central shaft 3, i.e. the rotary jet can be flushed through 360 °.
The upper joint 1 and the central shaft 3 are fixed through a set screw 4 after being connected in a threaded manner, and a first sealing ring 2 is arranged between contact surfaces of the upper joint 1 and the central shaft 3. The upper shell 6 is fixed through the set screw 4 after being in threaded connection with the connecting nipple 8. The connecting nipple 8 is fixed by the set screw 4 after being in threaded connection with the lower shell 10. The lower housing 10 is screwed to the lower joint 12 and then fixed by the set screw 4. The limiting sleeve 11 is fixed by the set screw 4 after being connected with the central shaft 3 in a threaded mode. The upper joint 1 and the central shaft 3, the upper casing 6 and the connecting nipple 8, the connecting nipple 8 and the lower casing 10, the lower casing 10 and the lower joint 12, and the limit sleeve 11 and the central shaft 3 are connected through threads and the set screw 4, so that the connection stability between the components is ensured, the connection nipple is not loosened, and the convenience of installation, maintenance and disassembly is realized.
The upper joint 1 is internally provided with threads which are rotary shoulder threads and are used for being connected with other tools for continuous oil pipe operation; the lower joint 12 is externally provided with threads, is a rotary shoulder type thread and is used for being connected with a flushing head for continuous oil pipe operation, and the lower joint 12 is internally provided with threads and can be used for being connected with a nozzle.

Working principle: when the tool to which the lower part of the hydraulic reversing mechanism is connected is provided with a throttling structure, such as a flushing tool, the lower joint 12 of the hydraulic reversing mechanism does not need to be connected with a throttling nozzle. The working pipe string with the hydraulic reversing mechanism and the flushing tool is lowered to a specified well depth, large-displacement liquid is pumped in, well shaft flushing work is started, throttling pressure difference is generated in the hydraulic reversing mechanism at the moment, hydraulic pressure is transmitted to the lower connector 12, the lower shell 10, the connecting nipple 8 and the upper shell 6 through the flushing tool, the parts move downwards, meanwhile, the compression spring 9 is compressed, and the elastic force is enhanced. In order to ensure the full-angle flushing operation of the shaft, the pumping of liquid is reduced or stopped at the moment, the throttling pressure difference in the hydraulic reversing mechanism is reduced or eliminated, and the compression spring 9 pushes the connecting nipple 8 to move upwards by elastic force, so that the connecting nipple 8, the upper shell 6, the lower shell 10, the lower joint 12 and the flushing tool move upwards simultaneously. Through the cooperation of the guide pin 7 and the guide groove 13, the connection nipple 8, the upper housing 6, the lower housing 10, the lower joint 12 and the flushing tool can be decomposed into axial rotation movement every time of upward and downward movement, and the rotation direction is fixed. By repeatedly increasing the displacement and reducing the displacement, unlimited axial rotation of the tool can be realized, and large-displacement and full-circumferential flushing operation of the shaft can be realized.
When the tool connected with the lower part of the hydraulic reversing mechanism is not provided with the throttling mechanism and is provided with the tool for fixing the inner diameter, the throttling nozzle is arranged at the lower joint 12, the throttling pressure difference is generated by the throttling nozzle, and the reversing principle of the hydraulic reversing mechanism is the same as that of the method. The unlimited axial rotation of a single downhole tool or tool string connected to the lower end of the reversing structure can also be achieved by repeatedly increasing and decreasing the displacement.
