[0033] The crankshaft 1 comprises 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 with the crank 13, and the connecting rod journal 16 is alternately arranged between every two cranks 13;

[0034] The distribution plate 4 includes a distribution plate 41, a matching component 42 and a distribution plate 43. One end of the distribution plate 41 is set on the end crank 13 through the matching component 42, and the distribution plate 43 is set on the shell 5. The other end of the distribution plate 41 is abutted against the distribution plate 43 through the matching component 42.

[0035] Furthermore, in the water motor of the present invention, a center oil hole 11 is provided in the middle of the crankshaft 1, and lubricating oil holes 17 are provided in the circumferential direction of the crank 13 and the connecting rod journal 16. The lubricating oil holes 17 are connected to the center oil hole 11, and oil is supplied to the lubricating oil holes 17 through the center oil hole 11, thereby realizing the overall lubrication of the crankshaft 1.

[0036] Furthermore, in the water motor of the present invention, the bearing bushing 2 cooperates with the connecting rod journal 16, the middle part of the bearing bushing 2 is fixedly connected to the output end of the emulsion cylinder 3, and the lubricating oil holes 17 in the circumferential direction of the bearing bushing 2 and the connecting rod journal 16 correspond to each other, thereby effectively ensuring the lubrication between the bearing bushing 2 and the connecting rod journal 16 and improving the service life of the crankshaft 1 and the bearing bushing 2.

[0037] Furthermore, in the water motor of the present invention, the end surface of the crank 13 is provided with three first pin holes 14, which are distributed in a regular triangle shape, and the end surface of the crank 13 is provided with three first spring holes 15, which are distributed in an inverted triangle shape.

[0038] Furthermore, in the water motor of the present invention, three second pin holes 411 are provided at one end of the ballast disc 41, and the three second pin holes 411 are distributed in a regular triangle shape. Three second spring holes 412 are provided on the ballast disc 41, and the three second spring holes 412 are distributed in an inverted triangle shape.

[0039] Further, in the water motor of the present invention, the matching component 42 includes a pin 421 and a spring 422, the pin 421 matches the first pin hole 14 and the second pin hole 411, one end of the pin 421 is respectively matched with the first pin hole 14, the other end of the pin 421 is respectively matched with the second pin hole 411, one end of the spring 422 is respectively matched with the first spring hole 15, and the other end of the spring 422 is respectively matched with the second spring hole 412, and the first pin hole 14 and the second pin hole 411 are distributed in an equilateral triangle, which effectively ensures The crank 13 effectively transmits the ballast flow disc 41, and provides a stable elastic supporting force to the ballast flow disc 41 through the inverted triangle distribution of the first spring hole 15 and the second spring hole 412, so that the ballast flow disc 41 and the ballast static disc 43 fixed on the shell 5 are pressed and matched with each other through the spring 422 between the crank 13 and the ballast flow disc 41. Under the action of the elastic force of the spring 422, the relatively rotating ballast flow disc 41 and the ballast static disc 43 fit tightly to avoid leakage, and at the same time, it can also avoid the sprain of the spring 422 when the crank 13 drives the ballast flow disc 41 to rotate.

[0040] Furthermore, in the water motor of the present invention, a central water tank 413 is arranged in the middle of the other end of the distribution flow disc 41, and grooves 414 are arranged around the central water tank 413 of the distribution flow disc 41. The number of grooves 414 corresponds to the number of emulsion cylinders 3. The central water tank 413 is connected with the grooves 414 respectively, so that after the emulsion enters the central water tank 413, the emulsion flow is distributed through the grooves 414, thereby controlling each emulsion cylinder 3 to perform alternating telescopic movements, thereby driving the crankshaft 1 to rotate and realizing the output torque.

[0041] Furthermore, in the water motor of the present invention, a water inlet 431 is provided on one side of the middle of the distribution static plate 43, and the water inlet 431 corresponds to the central water pool 413. Water outlets 432 are arranged on the distribution static plate 43 in parallel with the water inlet 431, and the number of water outlets 432 corresponds to the number of grooves 414, so that emulsion is provided to the central water pool 413 of the distribution flow plate 41 through the water inlet 431, and after being distributed through the grooves 414, the pressure of the emulsion in the emulsion cylinder 3 is increased through the water outlet 432 through the integrated valve 6.

[0042] Furthermore, in the water motor of the present invention, 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, wherein the input end of the integrated valve 6 is connected to the high-pressure pump station, and the water inlet 431 is connected to the low-pressure pump station, and the distribution flow disk 41 is driven to rotate by the crankshaft 1. As the position of the groove 414 changes continuously, the return liquid of different water outlets 432 on the distribution static disk 43 is controlled, and the corresponding return liquid flows back to the integrated valve 6 to control the movement of the corresponding emulsion cylinder 3, thereby ensuring that the distribution disk 4 is always in a low-pressure state.

[0043] Specifically, when the water motor is in use, the emulsion is provided to the water inlet 431 through the low-pressure pump station. After the emulsion enters the central water tank 413, it flows into the grooves 414 connected to the central water tank 413. The emulsion inflow time is distributed according to the length of the grooves 414, that is, the water outlet time of the water outlet 413 on the distribution plate 43. The emulsion distributed by the distribution plate 4 enters the integrated valve 6, and enters the emulsion cylinder 3 after being pressurized by the high-pressure pump station connected to the integrated valve 6, so that each emulsion cylinder 3 is controlled to perform alternating telescopic movements corresponding to the emulsion inflow time in the groove 414, 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 adopts emulsion as power, distributes emulsion through distribution plate, drives multiple emulsion cylinders to extend and retract alternately to drive crankshaft to rotate, has simple overall structure, low processing and manufacturing precision requirements, effectively reduces maintenance costs, and meets the explosion-proof requirements of coal mines.
