[0009] Furthermore, the articulated limiting member includes an articulated ball provided at the inner end of the axial plunger body, and an articulated sleeve is hingedly connected to the articulated ball.

[0010] Furthermore, the universal hinge ring includes a universal hinge ball arranged in the middle of the tail end of the rotor structure, a universal hinge sleeve is hinged on the universal hinge ball, and a control ring body is provided on the universal hinge sleeve.

[0011] Furthermore, the reciprocating linkage assembly includes a plurality of reciprocating control holes provided on the control ring body, the number of the reciprocating control holes is the same as the number of the axial piston bodies, and the reciprocating control hole is axially aligned with a corresponding one of the axial piston bodies;

[0017] In summary, the present invention has the following beneficial effects compared to the prior art:

[0018] The present invention solves the deficiencies in the existing water pump technology field. Through the structural setting of the present invention, it has the following advantages: it can flexibly and accurately adjust the water flow rate, and the reciprocating stroke of the axial piston body can be directly changed by adjusting the inclination angle of the inclined plate structure through the inclination control component; when the inclination angle increases, the piston stroke is lengthened, the single suction and discharge volume increases, and the water flow rate increases; when the inclination angle decreases, the piston stroke is shortened and the water flow rate decreases; compared with traditional water pumps that rely on pipeline valves to switch flow direction, the present invention realizes direction conversion through a single adjustment mechanism, simplifies the system complexity and reduces costs; multiple reciprocating piston structures are symmetrically distributed around the rotor center axis, and are subjected to uniform force during operation, reducing vibration and noise and improving stability; the articulated limiter and the universal articulated ring are connected by a ball joint, and cooperate with the reciprocating control hole to limit the piston movement trajectory, ensuring high-precision reciprocating motion, avoiding jamming, and improving transmission efficiency and service life. Dual adjustment mechanisms are independently controlled: the inclination angle and azimuth adjustment are independent of each other and can be combined to achieve multi-dimensional flow and flow direction control to adapt to complex working conditions; the azimuth adjustment component utilizes the self-locking function of the worm gear to fix the swash plate azimuth without the need for an additional locking device, thereby improving operational reliability; through the above-mentioned adjustment function, the water pump can be flexibly applied in industrial water supply, hydraulic systems, marine machinery and other fields, and is particularly suitable for scenarios that require dynamic flow control or flow direction switching. Compared with traditional plunger pumps, it has higher adaptability and cost-effectiveness. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] See also Figures 1-10 The present invention provides a slant disk plunger water pump, comprising a water pump valve body 1, wherein a rotating assembly 2 is provided in the water pump valve body 1, wherein a plurality of reciprocating plunger structures 3 are evenly distributed around the center of the rotating assembly 2, wherein one side of the water pump valve body 1 is provided with a water inlet channel 30 connected to the reciprocating plunger structure 3 on the corresponding side, and the other side is provided with a drainage channel 4 connected to the reciprocating plunger structure 3 on the corresponding side, wherein the inner end of the reciprocating plunger structure 3 is provided with a hinged limiter 5, and the inner end of the rotating assembly 2 is provided with a universal hinged ring 6. A reciprocating linkage assembly 7 is provided between the universal hinge ring 6 and the multiple hinge limit members 5, and a swash plate structure 8 is provided in the water pump valve body 1. The reciprocating linkage assembly 7 and the swash plate structure 8 cooperate with the reciprocating plunger structure 3 to control different rotation angle positions for extension and retraction. An azimuth control assembly 9 for controlling the azimuth angle of the swash plate structure 8 is provided on the water pump valve body 1, and an inclination control assembly 10 for controlling the inclination angle of the swash plate structure 8 is provided between the azimuth control assembly 9 and the swash plate structure 8.

[0031] The external power source drives the input shaft 201 to rotate, and the input shaft 201 is connected to the rotor structure 202, thereby driving the rotor structure 202 to rotate in the water pump valve body 1. This is the power starting point for the entire water pump operation and provides basic power for subsequent water suction and drainage actions.

[0032] Reciprocating Piston Motion: Multiple reciprocating piston structures 3 are evenly distributed around the central axis of the rotor structure 202. The axial piston body 302 is installed in the axial piston bore 301 and interacts with the swash plate structure 8 via a hinged stopper 5, a universal hinge ring 6, and a reciprocating linkage assembly 7. As the rotor structure 202 rotates, the stopper 702 rotates against the surface of the swash plate structure 8. Due to the tilt of the swash plate structure 8, the axial piston body 302 is forced to perform reciprocating linear motion within the axial piston bore 301.

[0033] Water suction and drainage action: When the axial plunger body 302 moves inward, negative pressure will be formed in the axial plunger hole 301, and water will be sucked in through the water inlet channel 30; when the axial plunger body 302 moves outward, pressure will be applied to the water in the hole, and the water will be discharged through the drainage channel 4, completing a cycle of water suction and drainage.

[0034] The tilt angle control assembly 10 can be used to adjust the tilt angle of the swash plate structure 8. By turning the annular knob 1082, the external and internal threads 1083 and 1084 engage to move the eccentric movable shaft 104 axially within the eccentric shaft hole 103. This, in turn, drives the swash plate structure 8 to change its tilt angle via the control link 107. As the tilt angle increases, the stroke of the axial piston body 302 increases, increasing the amount of water drawn in and out each time and boosting the water flow rate. As the tilt angle decreases, the stroke of the axial piston body 302 decreases, correspondingly reducing the water flow rate.

[0035] Principle of water flow direction change:

[0036] The azimuth control assembly 9 is used to adjust the azimuth angle of the swash plate structure 8. By rotating the adjustment worm 9032, it engages with the worm gear 9033 on the end surface of the azimuth adjustment circular plate 902, driving the azimuth adjustment circular plate 902 to rotate, thereby changing the azimuth of the swash plate structure 8. When the swash plate's azimuth changes, the sliding direction of the stopper 702 on the swash plate surface changes, causing the movement direction of the axial piston body 302 to change, thereby changing the direction of water flow.

[0037] The rotating assembly 2 of the present invention includes an input shaft 201 arranged at the front end of the water pump valve body 1 , and a rotor structure 202 is provided at the inner end of the input shaft 201 .

[0039] The hinged position-limiting member 5 of the present invention comprises a hinged ball 501 provided at the inner end of the axial plunger body 302 , and a hinged sleeve 502 is hingedly connected to the hinged ball 501 .

The reciprocating control hole 701 is axially aligned with a corresponding one of the axial piston bodies 302.
