Abstract
Description
Technical Field
[0001] This utility model relates to the field of water pump technology, and in particular to a slanted top structure used in a swashplate plunger water pump. Background Technology
[0002] Existing swashplate plunger pumps have limitations in controlling water flow direction, mostly only capable of pumping and draining water in a fixed direction, making it difficult to flexibly adjust the water flow direction according to actual usage scenarios. In working environments that require frequent changes in water flow direction, such as ship ballast water systems and irrigation systems in complex terrain, traditional swashplate plunger pumps cannot meet diverse needs, limiting their application range. Therefore, there is an urgent need to design a swashplate plunger pump that can effectively adjust the water flow direction.
[0003] Therefore, the existing water pump technology field needs further improvement. Utility Model Content
[0004] The purpose of this invention is to provide a sloping top structure for use in a swashplate plunger pump, which allows for flexible adjustment of the water flow direction by precisely controlling the rotation angle of the swashplate, thus adapting to different working scenarios and needs.
[0005] To achieve the above objectives, the present invention adopts the following solution: A sloping top structure for use in a swashplate plunger pump includes a pump stator assembly and a pump rotor assembly installed within the pump stator assembly. The pump rotor assembly has multiple plunger structures. The pump stator assembly has a rotation adjustment assembly with a sloping plate structure on it. A retaining adjustment assembly is provided between the pump rotor assembly and the multiple plunger structures to maintain the tail ends of the multiple plunger structures in contact with the surface of the sloping plate structure during rotation. The pump stator assembly has inlets and outlets on both sides for connecting the corresponding plunger structures.
[0006] Furthermore, the water pump stator assembly includes a water pump valve body, and a front cover is provided at the front end of the water pump valve body.
[0007] Furthermore, the water pump rotor assembly includes an input shaft rotatably mounted on the front cover, a rotor structure rotatably mounted inside the water pump valve body, and the input shaft and the rotor structure are fixedly connected.
[0008] Furthermore, multiple plunger structures are evenly distributed around the axis of the rotor structure; each plunger structure includes a plunger hole disposed on the rotor structure, and a plunger is movably disposed within the plunger hole.
[0009] Furthermore, the rotary adjustment assembly includes a fixed rear cover disposed at the rear end of the water pump valve body, an adjustment shaft is rotatably disposed on the fixed rear cover, the swashplate structure is fixedly installed on the adjustment shaft, and a control structure for controlling the rotation angle of the adjustment shaft is disposed on the fixed rear cover.
[0010] Furthermore, the control structure includes a worm gear mounting seat disposed on the fixed rear cover, an adjusting worm gear rotatably disposed on the worm gear mounting seat, and a worm wheel disposed at the outer end of the adjusting shaft, the worm wheel and the adjusting worm gear engaging in transmission.
[0011] Furthermore, the retaining adjustment assembly includes a universal joint ball structure located at the center of the tail of the rotor structure. The universal joint ball structure is provided with a swing disk, and the swing disk is provided with a plurality of positioning holes. The number of positioning holes is the same as the number of plungers. The tail of the plunger is provided with a synchronous clamping member for synchronously moving with the axial position of a corresponding positioning hole. The synchronous clamping member is disposed close to the surface of the swashplate structure.
[0012] In summary, the advantages of this utility model over the prior art are: This invention addresses the shortcomings of existing water pump technology. Through its structural design, the rotation angle of the swashplate structure is precisely controlled by a rotary adjustment component, thereby altering the plunger's motion trajectory and the change in plunger cavity volume. This enables flexible adjustment of the water flow direction, meeting the needs of various complex working scenarios. The design of the adjustment component ensures that the plunger remains stably in contact with the swashplate structure and performs corresponding reciprocating motion during changes in the swashplate's rotation angle, improving the stability and reliability of the water pump. The worm gear transmission control structure offers advantages such as compact structure, large transmission ratio, and good self-locking performance, facilitating precise control of the swashplate's rotation angle and providing convenient and highly accurate operation.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0015] Please see Figures 1-4 This utility model provides a sloping top structure applied in a swashplate plunger pump, including a pump stator assembly 1 and a pump rotor assembly 2 installed in the pump stator assembly 1. The pump rotor assembly 2 is provided with a plurality of plunger structures 3. The pump stator assembly 1 is provided with a rotation adjustment assembly 4. The rotation adjustment assembly 4 is provided with a sloping plate structure 5. A holding adjustment assembly 6 is provided between the pump rotor assembly 2 and the plurality of plunger structures 3 to keep the tails of the plurality of plunger structures 3 close to the surface of the sloping plate structure 5 for rotation. The pump stator assembly 1 is provided with an inlet 100 and an outlet 200 on both sides for connecting the plunger structures 3 on the corresponding side.
[0016] Power transmission: The input shaft 201 is connected to an external power source. When it rotates, it drives the rotor structure 202, which is fixed to it, to rotate inside the water pump valve body 101, providing power for the operation of the water pump.
[0017] Plunger reciprocating motion: Multiple plungers 302, evenly distributed around the axis of rotor structure 202, reciprocate within plunger holes 301 as rotor structure 202 rotates. When the plunger 302 moves outward, the volume of plunger hole 301 decreases, draining water outward; when it moves inward, the volume increases, creating negative pressure and drawing in water.
[0018] Swashplate angle adjustment: Rotate the adjusting worm gear 4032, which, through meshing with the worm wheel 4033, drives the adjusting shaft 402 and the swashplate structure 5 fixed thereon to rotate, thereby changing the swashplate angle.
[0019] Maintaining synchronization: The universal joint ball structure 601, the swing disk 602, and the synchronization clamping member 604 in the maintaining adjustment assembly 6 work together to ensure that the tail of the plunger 302 always fits against the surface of the swashplate structure 5. When the swashplate angle changes, the synchronization clamping member 604 drives the plunger 302 to change its motion pattern.
[0020] Water flow direction adjustment: The angle change of the swashplate structure 5 changes the movement law of the plunger 302, adjusts the sequence of changes in the volume of the plunger cavity, and realizes that the water flows in from the inlet 100 and out from the outlet 200, or flows in the opposite direction, thus completing the water flow direction adjustment.

The universal joint ball structure 601 is provided with a swing disk 602. The swing disk 602 is provided with a plurality of positioning holes 603. The number of positioning holes 603 is the same as the number of plungers 302.
