[0032] As Figures 1 to 5As shown in the figure, the water motor of the present utility model includes a crankshaft 1, a bearing bush 2, an emulsion cylinder 3, a distribution disk 4, a housing 5 and an integrated valve 6.

Among them, the crankshaft 1 is connected to the housing 5 through bearings to achieve rotation. One end of the emulsion cylinder 3 is connected to the housing 5, and the output end of the emulsion cylinder 3 is connected to the crankshaft 1 through the bearing bush 2 to provide power for the crankshaft 1. The distribution disk 4 is arranged at one end of the crankshaft 1, and the distribution disk 4 is connected to the emulsion cylinder 3 through the integrated valve 6 to control the expansion and contraction of the emulsion cylinder 3. Among them:

[0033] The crankshaft 1 includes a main journal 12, a crank 13 and a connecting rod journal 16. The crank 13 is coaxial with the main journal 12. The crank 13 is arranged at one end of the main journal 12. The connecting rod journal 16 is eccentric to the crank 13. The connecting rod journals 16 are alternately arranged between every two cranks 13;

[0034] The distribution disk 4 includes a movable distribution disk 41, a matching component 42 and a stationary distribution disk 43. One end of the movable distribution disk 41 is arranged on the end crank 13 through the matching component 42. The stationary distribution disk 43 is arranged on the housing 5. The other end of the movable distribution disk 41 abuts against the stationary distribution disk 43 through the matching component 42.

[0035] Further, in the water motor of the present utility model, a central oil hole 11 is arranged in the middle of the crankshaft 1. Lubricating oil holes 17 are arranged in the circumferential direction of the crank 13 and the connecting rod journal 16. The lubricating oil holes 17 are communicated with the central oil hole 11, and oil is supplied to the lubricating oil holes 17 through the central oil hole 11, so as to realize the overall lubrication of the crankshaft 1.

[0036] Further, in the water motor of the present utility model, the bearing bush 2 is matched with the connecting rod journal 16. The middle of the bearing bush 2 is fixedly connected to the output end of the emulsion cylinder 3. The lubricating oil holes 17 in the circumferential direction of the bearing bush 2 correspond to the connecting rod journal 16, so as to effectively ensure the lubrication between the bearing bush 2 and the connecting rod journal 16 and improve the service life of the crankshaft 1 and the bearing bush 2.

[0037] Further, in the water motor of the present utility model, three first pin holes 14 are arranged on the end face of the crank 13. The three first pin holes 14 are distributed in an equilateral triangle. Three first spring holes 15 are arranged on the end face of the crank 13. The three first spring holes 15 are distributed in an inverted triangle.

[0038] Further, in the water motor of the present utility model, three second pin holes 411 are arranged at one end of the movable distribution disk 41. The three second pin holes 411 are distributed in an equilateral triangle. Three second spring holes 412 are arranged on the movable distribution disk 41. The three second spring holes 412 are distributed in an inverted triangle.

[0039] Further, in the water motor of the present utility model, the cooperation assembly 42 includes a pin shaft 421 and a spring 422. The pin shaft 421 is matched with the first pin shaft hole 14 and the second pin shaft hole 411. One end of the pin shaft 421 is in clearance fit with the first pin shaft hole 14 respectively, and the other end of the pin shaft 421 is in clearance fit with the second pin shaft hole 411 respectively. One end of the spring 422 is in clearance fit with the first spring hole 15 respectively, and the other end of the spring 422 is in clearance fit with the second spring hole 412 respectively. The first pin shaft hole 14 and the second pin shaft hole 411 are distributed in an equilateral triangle, effectively ensuring the effective transmission of the crank 13 to the flow distribution moving disk 41. The first spring hole 15 and the second spring hole 412 are distributed in an inverted triangle, effectively providing a stable elastic supporting force for the flow distribution moving disk 41, so that the flow distribution moving disk 41 and the flow distribution static disk 43 fixed on the housing 5 are pressed and fitted through the spring 422 between the crank 13 and the flow distribution moving disk 41. Under the action of the elastic force of the spring 422, the relatively rotating flow distribution moving disk 41 and the flow distribution static disk 43 are closely attached, avoiding liquid leakage, and at the same time, it can also avoid the sprain of the spring 422 when the crank 13 drives the flow distribution moving disk 41 to rotate.

[0040] Further, in the water motor of the present utility model, a central water pool 413 is arranged in the middle of the other end of the flow distribution moving disk 41. The flow distribution moving disk 41 is provided with grooves 414 around the central water pool 413. The number of grooves 414 corresponds to the number of emulsion cylinders 3. The central water pool 413 is communicated with the grooves 414 respectively, so that after the emulsion enters the central water pool 413, the emulsion flow is distributed through the grooves 414, thereby controlling each emulsion cylinder 3 to perform an alternating telescopic movement, thereby driving the crankshaft 1 to rotate and realizing the output torque.

[0041] Further, in the water motor of the present utility model, a water inlet 431 is arranged on one side of the middle of the flow distribution static disk 43. The water inlet 431 corresponds to the central water pool 413. The water outlet 432 is arranged on the flow distribution static disk 43 in an arrangement corresponding to the water inlet 431. The number of water outlets 432 corresponds to the number of grooves 414. Thus, the emulsion is provided to the central water pool 413 of the flow distribution moving disk 41 through the water inlet 431, and after being distributed through the grooves 414, the emulsion increases the pressure of the emulsion cylinder 3 through the water outlet 432 and the integrated valve 6 respectively.

[0042] Further, in the water motor of the present utility model, the water outlet 432 is connected to the integrated valve 6, and the control end of the integrated valve 6 is connected to the emulsion cylinder 3. Among them, the input end of the integrated valve 6 is connected to the high-pressure pumping station, and the water inlet 431 is connected to the low-pressure pumping station. The crankshaft 1 drives the flow distribution moving disk 41 to rotate. As the position of the groove 414 changes continuously, the liquid return of different water outlets 432 on the flow distribution static disk 43 is controlled, and the corresponding liquid return flows back to the integrated valve 6 to control the movement of the corresponding emulsion cylinder 3, so as to ensure that the flow distribution disk 4 is always in a low-pressure state.

[0043] Specifically, when the water motor is in use, an emulsion liquid is provided to the water inlet 431 through a low-pressure pumping station. After the emulsion liquid enters the central water tank 413, it flows into the grooves 414 communicated with the central water tank 413 respectively. The inflow time of the emulsion liquid is allocated according to the length of the grooves 414, that is, the water outlet time of the water outlet 413 on the flow distribution static disc 43. The emulsion liquid after being distributed by the flow distribution disc 4 enters the integrated valve 6, and after being pressurized by the high-pressure pumping station connected to the integrated valve 6, it enters the emulsion liquid cylinder 3, so that each emulsion liquid cylinder 3 respectively corresponds to the control of the inflow time of the emulsion liquid in the grooves 414 to perform an alternating telescopic movement, thereby driving the crankshaft 1 to rotate and realizing the output torque.

[0044] In summary, compared with the prior art, the water motor of the present invention has the following advantages and beneficial effects:

[0045] The present invention uses emulsion liquid as power, distributes the emulsion liquid through a flow distribution disc, drives multiple emulsion liquid cylinders to alternately expand and contract to drive the crankshaft to rotate. The overall structure is simple, the processing and manufacturing precision requirements are low, the maintenance cost is effectively reduced, and at the same time, the explosion-proof requirements in coal mines are met.
