Description

Technical Field

[0001] This application belongs to the technical field of gear pump structural design, and specifically relates to a gear pump. Background Technology

[0002] A gear pump is a rotary pump that relies on changes in working volume to transport liquids. It typically consists of two gears, a pump body, and front and rear covers forming two enclosed spaces. When the gears rotate, the volume of the space on the disengaged side increases, creating a partial vacuum and drawing liquid in through the inlet. Conversely, the volume of the space on the meshing side decreases, squeezing liquid out through the outlet.

[0003] In the prior art, the water inlet of a gear pump is usually connected to the water storage module via a hose, and due to the limitations of the hose structure, the water inlet can only be used with a single water storage module.

[0004] The inventors discovered that in scenarios where multiple water storage modules are used simultaneously, only the liquid in each module can be discharged sequentially, and the liquid in multiple modules cannot be discharged simultaneously, which limits the usage and fails to meet the increasingly diverse needs of users.

[0019] A limiting screw is fixedly disposed on the side of the alignment plate opposite to the positioning shaft, and is adapted to contact the outer peripheral surface of the water collecting component; and

[0020] A positioning nut is threaded to the outer end of the limiting screw to be suitable for clamping the water collection component with the alignment plate.

[0021] In one possible implementation, the water collection element includes:

[0022] The housing has a hollow interior and a single-sided opening; the housing is located on the side facing the water inlet, and its opening faces the pump body; and

[0023] A cover is provided on the open side of the housing to close the opening of the housing; the cover has a water outlet, and the water outlet is connected to the water inlet through the rotating connection structure.

[0024] In one possible implementation, a retaining ring is provided on the open side of the housing, the retaining ring surrounding the outlet; the retaining ring abuts against the outer side of the cover to restrict the cover from moving away from the housing;

[0025] The retaining ring has a first through hole, and the housing has a second through hole; when the retaining ring abuts against the cover, the first through hole and the second through hole are connected.

[0026] The retaining ring further includes:

[0027] Mounting bolts, adapted to be inserted into the interconnected first through hole and second through hole; and

[0028] Install a nut, which is threadedly connected to the mounting bolt, to engage with the head of the mounting bolt to clamp the retaining ring and the housing.

[0029] In one possible implementation, the water conduit includes:

[0030] A rigid pipe section is detachably connected to the outer surface of the water collecting component and communicates with the interior of the water collecting component; a control valve is disposed on the rigid pipe section to control the opening or closing of the rigid pipe section; and

[0031] The flexible tube is fitted onto the rigid tube and is used to communicate with the water storage module.

[0032] In one possible implementation, the outer surface of the water collecting component has a plurality of connecting pipe sections corresponding one-to-one with the plurality of water pipes; each of the connecting pipe sections is in communication with the interior of the water collecting component and also in communication with the rigid pipe section;

When suction is generated at the inlet, the liquid inside the water collector enters the inlet through the rotating connection structure, thus supplying liquid. Furthermore, by adjusting the control valve, the number of water pipes connected to the water collector can be controlled. When the pump body starts, all open water pipes can discharge liquid into the water collector, achieving the technical objective of multiple water storage modules simultaneously supplying liquid to the gear pump.

Finally, the position of the water collector is fixed by the locking structure, and the installation of the gear pump is completed.

Therefore, they should not be construed as limitations on this application.

[0058] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0059] Please refer to the following: Figures 1 to 11 The gear pump provided in this application will now be described. The gear pump proposed in this application includes a pump body 1, a water collecting component 2, and multiple water pipes 6.

[0060] The pump body 1 has a conventional structure of a gear pump, which has an inlet 11 that communicates with the interior. In actual use, the rotation of the gear inside the pump body 1 provides suction to draw liquid in from the inlet 11 and squeeze it out from the outlet on the other side.

[0061] The water collection component 2 is located on the side facing the water inlet 11, and it has an internal hollow structure. In actual manufacturing, the water collection component 2 is usually made of rigid material, and steel is often selected.

[0062] The water collecting component 2 is connected to the pump body 1 via a rotating connection structure 3, allowing the interior of the water collecting component 2 to communicate with the water inlet 11 and forming a rotational degree of freedom around the central axis of the water inlet 11. When the gear pump is installed in different operating scenarios, rotating the water collecting component 2 ensures an effective locking combination with different environments. A locking structure exists between the water collecting component 2 and the pump body 1 to restrict the rotation of the water collecting component 2 relative to the pump body 1, improving the stability and strength of the overall structure.

[0063] Multiple water pipes 6 are used to connect one-to-one with multiple water storage modules; each water pipe 6 is connected to the inside of the water collection component 2, and each water pipe 6 is connected to a control valve 10; in water storage modules that do not require drainage, by adjusting the control valve 10 to switch the corresponding water pipe 6 to the closed state, the water storage module can be isolated, ensuring that the suction provided by the pump body 1 only acts on the liquid of other water storage modules.

[0064] In this embodiment, the pump body 1 provides suction to the inlet 11. When suction is generated at the inlet 11, the liquid inside the water collector 2 enters the inlet 11 through the rotating connection structure 3 to supply liquid. Based on this, the number of water pipes 6 connected to the water collector 2 can be controlled by adjusting the control valve 10. When the pump body 1 starts, all 6 open water pipes can discharge liquid into the water collector 2, thus achieving the technical objective of multiple water storage modules simultaneously supplying liquid to the gear pump.

[0065] During the installation of the pump body 1, the required installation angle of the water collection component 2 can be obtained by first driving the water collection component 2 to rotate relative to the pump body 1, thereby adapting to different installation environments. Finally, the position of the water collection component 2 is fixed by the locking structure, thus completing the installation of the gear pump.

[0066] The gear pump provided in this embodiment, compared with the prior art, can realize a system layout combining multiple water storage modules and a single gear pump, so as to realize the sequential or simultaneous discharge of liquid in multiple water storage modules, thereby meeting different user needs and improving the market competitiveness of the product.

[0067] In some embodiments, such as Figure 3 and Figure 5 As shown, the rotating connection structure 3 includes a protruding tube 31 and a sleeve 32.

[0068] The convex tube 31 is fixedly installed on the side of the pump body 1 facing the water collecting component 2, and is coaxially connected with the water inlet 11.

[0069] The sleeve 32 is fitted around the outer periphery of the convex tube 31 and has a rotational degree of freedom around the central axis of the convex tube 31.

[0070] The water collecting component 2 is connected to (but not connected to) the sleeve 32 on the side facing the pump body 1, and an outlet 221 communicating with the inside of the sleeve 32 is provided at the connection point.

[0071] In some embodiments, such as Figure 2 , Figure 4 and Figure 9 As shown, the locking structure includes multiple positioning shafts 4 and multiple docking parts 5.

[0072] Multiple positioning shafts 4 are all set on the side of the pump body 1 facing the water collecting component 2, and their axial direction is parallel to the direction of the pump body 1 facing the water collecting component 2.

[0073] Multiple docking parts 5 are connected one-to-one with multiple positioning shafts 4, and are all suitable for connecting with the outer edge of the water collecting part 2 to restrict the rotation and movement of the water collecting part 2 relative to the pump body 1.

[0074] It should be noted that, based on water collection component 2 Figure 1When the position shown is rotated relative to the pump body 1, that is, when the required fixed position of the water collecting component 2 changes, some of the connecting parts 5 do not do work, and at least three connecting parts 5 are still connected to the water collecting component 2, thereby achieving the locking effect of the water collecting component 2.

[0075] In some embodiments, such as Figure 2 and Figure 9 As shown, a threaded groove 41 is provided on the outer end face of the positioning shaft 4, and the mating part 5 includes a positioning plate 51, a limiting screw 52 and a positioning nut 53.

[0076] Alignment plate 51 is located outside the positioning shaft 4; a mating screw 511 is coaxially provided on the side of alignment plate 51 facing the positioning shaft 4. The mating screw 511 is adapted to be threadedly connected to the threaded groove 41 so that when alignment plate 51 rotates, alignment plate 51 moves axially along positioning shaft 4 and realizes the combination of alignment plate 51 and positioning shaft 4.

[0077] The limiting screw 52 is fixedly installed on the side of the alignment plate 51 facing away from the positioning shaft 4, and is adapted to be in contact with the outer peripheral surface of the water collecting component 2, thereby restricting the water collecting component 2 from moving in a direction perpendicular to its own axis.

[0078] The positioning nut 53 is threaded to the outer end of the limiting screw 52 to cooperate with the positioning plate 51 to clamp the water collecting component 2, ensuring that the water collecting component 2 is stably limited.

[0079] In some embodiments, such as Figure 10 and Figure 11 As shown, the water collection component 2 includes a housing 21 and a cover 22.

[0080] The housing 21 has an internally hollow structure with a single-sided opening; the housing 21 is located on the side facing the water inlet 11, and its opening faces the pump body 1.

[0081] The cover 22 is provided on the open side of the housing 21 to close the opening of the housing 21; the cover 22 has an outlet 221, and the outlet 221 is connected to the inlet 11 through the rotating connection structure 3.

[0082] By designing the above combined structure, the maintenance and upkeep process of water collection component 2 can be optimized, that is, specific components can be replaced individually to ensure the normal operation of the overall structure.

[0083] It should be noted that the outlet 221 mentioned here is the same outlet 221 that is connected to the inside of the sleeve 32. This explanation is based on the lower-level expansion of the water collection component 2 to illustrate the location and connection principle of the outlet 221.

[0084] To achieve the combination of housing 21 and cap 22, in some embodiments, such as Figure 10 and Figure 11As shown, a retaining ring 7 is provided on the open side of the shell 21. The retaining ring 7 is arranged around the water outlet 221, that is, it avoids the water outlet 221 and does not interfere with the drainage process of the water outlet 221.

[0085] After actual assembly, the retaining ring 7 abuts against the outer side of the cover 22 to restrict the cover 22 from moving away from the housing 21, thereby realizing the assembly of the housing 21 and the cover 22.

[0086] The retaining ring 7 has a first through hole 71, and the housing 21 has a second through hole 211; when the retaining ring 7 abuts against the cover 22, the first through hole 71 and the second through hole 211 are connected; based on this, the retaining ring 7 also includes a mounting bolt 72 and a mounting nut 73.

[0087] Mounting bolt 72 is adapted to be inserted into the interconnected first through hole 71 and second through hole 211, with its head abutting the outer side of the retaining ring 7 and its other end extending to the outside of the housing 21.

[0088] The mounting nut 73 is threadedly connected to the protruding part of the mounting bolt 72 to clamp the retaining ring 7 and the housing 21 with the head of the mounting bolt 72, thereby realizing the combination of the retaining ring 7 and the housing 21 and ensuring the stability of the retaining ring 7's combined limiting effect on the housing 21 and the cover 22.

[0089] In some embodiments, such as Figure 6 and Figure 7 As shown, the water pipe 6 includes a rigid pipe section 61 and a flexible pipe section 62.

[0090] The rigid pipe section 61 is detachably connected to the outer side of the water collection component 2 and communicates with the interior of the water collection component 2; the control valve 10 is provided on the rigid pipe section 61 to control the opening or closing of the rigid pipe section 61.

[0091] The flexible hose 62 is fitted onto the rigid pipe 61 and is used to connect with the water storage module; in actual use, different lengths of flexible hose 62 can be selected according to the design position of the pump body 1.

[0092] It should be noted that the rigid tube section 61 has a boss on its outer periphery, and the flexible tube section 62 can be fitted onto the outer periphery of the boss, thus forming an annular recessed structure. Based on this, by winding a steel wire rope or other structure around the outer periphery of the recessed structure, the rigid tube section 61 and the flexible tube section 62 can be locked together, improving their resistance to axial tensile forces when combined. In actual assembly, they can also be fixed in other ways, such as by providing a metal ring at the end of the flexible tube section 62 and welding the metal ring to the outer wall of the rigid tube section 61; no specific limitation is made here.

[0093] In some embodiments, such as Figure 6 and Figure 8As shown, the outer surface of the water collecting component 2 has multiple connecting pipe sections 8 that correspond one-to-one with multiple water pipes 6; wherein each connecting pipe section 8 is connected to the interior of the water collecting component 2 and is also connected to the rigid pipe section 61.

[0094] To achieve the combination of the rigid pipe section 61 and the connecting pipe section 8, the rigid pipe section 61 has a first flange 81 integrally connected to the connecting pipe section 8 at the junction with the water collection component 2, and a second flange 611 connected to the first flange 81 on the rigid pipe section 61; furthermore, the first flange 81 has a fixing screw 811, and the second flange 611 has a through hole 6111 suitable for the fixing screw 811 to pass through. The fixing screw 811 passes through the through hole 6111 and extends out, and the extended part of the fixing screw 811 is threadedly connected to a locking nut 812 that abuts against the outer side of the second flange 611.

[0095] In some embodiments, such as Figure 6 and Figure 8 As shown, multiple filter screens 9 are embedded inside the connecting pipe section 8.

[0096] By adopting the above technical solution, the filter screen 9 plays the role of filtering liquid impurities, preventing impurities from entering the pump body 1 and affecting the normal operation of its internal gears, ensuring that the gears do work normally, and extending the service life of the pump body 1.

[0097] In some embodiments, such as Figure 6 and Figure 8 As shown, the connecting pipe section 8 has a reserved opening 82 communicating with its interior; in this embodiment, the cross-section of the reserved opening 82 is semi-circular, that is, it penetrates half of the circle in the radial cross-section of the connecting pipe section 8. Based on this, the filter screen 9 also includes an arc-shaped member 91, which is coaxially disposed on the outside of the filter screen 9, and the inner side of the arc-shaped member 91 is connected to the outer peripheral surface of the filter screen 9.

[0098] When the filter screen 9 is inside the connecting pipe section 8, the arc-shaped member 91 can be embedded into the opening of the reserved port 82 to close the reserved port 82; and when the rigid pipe section 61 is fitted around the outer periphery of the connecting pipe section 8, the rigid pipe section 61 can restrict the arc-shaped member 91 from disengaging from the reserved port 82, thereby fixing the filter screen 9 relative to the connecting pipe section 8, ensuring that the filter screen 9 can stably perform the filtering effect on impurities in the liquid, and extending the service life of the pump body 1.

[0099] It should be noted that the length of the reserved opening 82 in the axial direction of the connecting pipe section 8 is L; correspondingly, there are X filter screens 9, and the thickness of each arc-shaped component 91 in the axial direction of the filter screen 9 is L / X. That is to say, after multiple filter screens 9 are assembled in place at the same time, multiple arc-shaped components 91 abut against each other to form a mating component with a thickness of L. Since the thickness of this mating component is equal to the length of the reserved opening 82, it can seal the reserved opening 82 and prevent liquid from overflowing.

[0100] The above content is only a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
