The adjusting top ring 403 penetrates through the water pressing block 307, the water pressing block 307 is connected with the sleeve 101 in a sliding mode through a sliding rail sliding groove, the installation direction of the sliding rail sliding groove is parallel to the axis direction of the sleeve 101, the sleeve 101 is located between the adjusting top ring 403 and the installing ring 402, and the inner side wall of the installing ring 402 is in threaded connection with the outer side wall of the sleeve 101.
The working principle is as follows:
the pipe fitting adapter 102 is communicated with an external high-pressure pump by using a pipe fitting, water is pumped by using the high-pressure pump to provide basic hydrodynamic force for the device, the device is in an initial state, the adjusting top ring 403 is inserted into the stress plate 302, the adjusting top ring 403 plays a role in pushing the sleeve 101 towards the direction of the thrust plate 301, so that the stress plate 302 cannot be pushed towards the axis direction of the sleeve 101 by the cambered thrust block 303 in a rotating state, the device can be ensured to maintain a continuous high-pressure jet state, water flows enter the region of the turbine blade 201 through the pipe fitting adapter 102, the turbine blade 201 drives the rotating shaft 200 to rotate under the impact of the water flows, the rotating shaft 200 rotates to drive the thrust plate 301 to rotate, the stress plate 302 is jacked by the adjusting top ring 403 to be incapable of axially moving, at the moment, the cambered thrust block 303 generates a transverse thrust force on the cambered surface stress block 304, the cambered surface stress block 304 drives the stress plate 302 to rotate, and the bearing 202, the axis of the rotating shaft 200 is always kept coincident with the axis of the sleeve 101, water flow enters the region of the telescopic pressure water column 306 through the bearing through hole 203 and the water flow through hole 305, because one end of the stress plate 302 close to the telescopic pressure water column 306 is an inclined surface, in the process of rotating the stress plate 302, the ball 309 can roll along the periphery of the inclined surface in the stress plate 302, so as to achieve the effect that the telescopic pressure water column 306 cannot rotate along with the stress plate 302, the stress plate 302 can drive the collar 310 to axially reciprocate, the collar 310 can drive the telescopic pressure water column 306 to axially reciprocate, when moving towards one side close to the stress plate 302, water pressure can push the water inlet blocking ball 312 towards the water inlet blocking block 313, water flow can enter the telescopic pressure water column 306 from the middle part of the water inlet blocking ball 311, the water inlet blocking block 313 plays a role in limiting the water inlet blocking ball 312, so that the water inlet blocking ball 312 is always kept in the region close to the water inlet blocking ball blocking ring 311, with the continuous rotation of the force bearing plate 302, the inclined plane pushes the telescopic pressurized water columns 306 towards the pressurized water block 307, at this time, the water outlet ball retainer 315 is pushed by the external water flow towards the inside of the telescopic pressurized water columns 306, and under the action of the relative movement direction of the water outlet ball retainer 315 and the telescopic pressurized water columns 306, the water outlet ball retainer 315 moves towards the water outlet stopper 316, the water flow which is extruded into the telescopic pressurized water columns 306 by the water inlet ball retainer ring 311 in front will eject the telescopic pressurized water columns 306 by the water outlet ball retainer ring 314, in this process, a secondary pressurization effect on the water flow is achieved, because the telescopic pressurized water columns 306 are not designed as one, in the rotation process of the force bearing plate 302, a push-pull effect will be sequentially generated on the adjacent telescopic pressurized water columns 306, so that each telescopic pressurized water column 306 can eject water flow sequentially, if only one telescopic pressurized water column 306 can cause the effect of alternately generating high and low water ejection strength, the exploitation efficiency of the oil shale is greatly influenced, in some special cases, such high-pressure water flow is not needed, for example, when the exploitation debris is cleaned to be exploited continuously, only more debris is generated by adopting high-pressure impact, at the moment, the arc-shaped water outlet ring 401 is rotated, the mounting ring 402 is moved towards the direction close to the arc-shaped water outlet ring 401 along the screw thread, the adjusting top ring 403 is driven to move towards the direction far away from the stressed plate 302, until the adjusting top ring 403 is separated from the area of the top ring groove 404, at the moment, the stressed plate 302 loses the axial limiting function of the adjusting top ring 403, when the thrust plate 301 rotates, the cambered thrust block 303 pushes the cambered stressed block 304 towards the direction far away from the thrust plate 301 under the inclined plane effect, then under the spring effect in the water pressure groove 308, the stressed plate 302 is pushed back towards the thrust plate 301, the thrust plate 301 continuously rotates to enable the stressed plate 302 to do reciprocating motion, and further drive all the telescopic water pressure columns 306 to do reciprocating motion together, at the moment, all the telescopic pressure water columns 306 are simultaneously used as water flow channels, the cross section of water flow is increased, the water pressure is lower than that of the telescopic pressure water columns 306 under the sequential pressurized water state, at the moment, the jet flow adjusting head 103 can jet high-flow low-pressure water flow to adapt to the requirement of a mining environment, the device improves the adaptability in the mining process of the oil shale by switching the common jet flow and the continuous high-pressure jet flow, and utilizes the continuous high-pressure jet flow to carry out high-pressure impact mining on the oil shale, the high-pressure jet flow of the device has the characteristic of stable jet flow, so that the mining efficiency of the oil shale can be effectively improved, a single pressurizing assembly in the prior art has high-low pressure discontinuity of the jetted water flow, the mining efficiency is influenced, the water flow pressurizing channel in the annular design is arranged in the device, so that the continuous and uninterrupted effect can be realized on the basis of high pressure water flow, the device, the environmental adaptability and flexibility of the device are improved.
