Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic water pumps, and more specifically, to a hydraulic water pump. Background Art

[0002] A hydraulic water pump is a pump driven by hydraulic power and is primarily used in applications requiring high pressure or high flow rates, such as industry, construction, agricultural irrigation, and firefighting. These pumps convert hydraulic energy into mechanical energy through a hydraulic motor or cylinder, which in turn drives the pump's impeller to pump water or other fluids. Hydraulic water pumps are particularly effective in situations requiring pumping in urban areas, flooded farmland, or low-lying areas, preventing flooding from impacting urban infrastructure, farmland, and residents.

[0003] The current hydraulic water pump has some defects. When the current hydraulic water pump is working, there are no protective measures between the impeller blades inside the water pump and the inner wall of the water pump casing. A gap is left between the impeller and the inner wall of the casing to ensure the normal rotation of the impeller. However, during use, some impurities such as sand in the water body will be stuck in this gap. Over time, the rotation of the impeller will cause wear on the edge of the impeller and the inner wall of the casing, causing damage to the impeller and the casing, affecting its use effect and service life; and it will also cause the gap between the impeller and the inner wall of the casing to become larger and larger, the pumping efficiency becomes lower, and the pumping effect is seriously affected.

[0004] Therefore, it is necessary to provide a hydraulic water pump to solve the above technical problems. Utility Model Content

[0005] The purpose of this utility model is to provide a hydraulic water pump to solve the above technical problems.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0008] an impeller, disposed in the water pump housing and connected to the hydraulic motor via a shaft;

[0009] A wear-resistant sealing ring is provided on the inner wall of the water pump housing and is located between the inner wall of the water pump housing and the outer wall of the impeller;

[0010] The impeller comprises a shell, blades, an inlet and a side outlet, wherein the inlet and the side outlet are respectively arranged at the bottom and the side of the shell, and the blades are arranged on the inner wall of the shell.

[0011] Furthermore, a drainage channel is provided inside the water pump housing, the water inlet and the water outlet are both connected to the drainage channel, and the inlet and side outlet of the impeller are also connected to the drainage channel.

[0012] Furthermore, a filter retaining frame is provided at the bottom of the water pump housing, and the filter retaining frame includes:

[0013] Two fixing rings are provided at the bottom of the water pump housing, and the two fixing rings are connected by a plurality of connecting plates;

[0014] The blocking member is detachably arranged between the two fixing rings.

[0015] Furthermore, a plurality of mounting holes are provided in a ring shape on the fixing ring, and the blocking member includes a connecting rod, and both ends of the connecting rod are provided with retractable mounting rods, and the mounting rods are adapted to the mounting holes.

[0016] Furthermore, an inner recessed cavity is provided inside the mounting rod, the connecting rod is slidably connected to the inner wall of the inner recessed cavity, and an elastic member is provided between the end of the connecting rod and the inner wall of the inner recessed cavity.

[0017] Furthermore, the inner side wall of the connecting plate is provided with a plurality of retaining rings.

[0018] Furthermore, the retaining ring is provided with a plurality of limiting holes, and the connecting rod is provided with screw holes matched with the limiting holes.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. In this solution, the cooperation between the impeller shell and the wear-resistant sealing ring can greatly reduce the situation where the water flow is guided between the impeller and the inner wall of the water pump as in the existing method, so that the wear-resistant sealing ring can play a good sealing and protective role, and avoid the situation where the impeller is directly close to the inner wall of the water pump shell, greatly reducing the wear of the impeller and the inner wall of the water pump shell, and improving their service life; the coordinated use of the impeller and the wear-resistant sealing ring can ensure the long-term and effective use of the hydraulic water pump, with high pumping efficiency and good pumping effect.

[0021] 2. The filter baffle in this solution can perform preliminary filtration on the water. Through the cooperation of the fixing ring, the connecting plate and the blocking member, it can prevent larger impurities and garbage in the water from entering the hydraulic water pump, which can greatly prevent the blockage and damage of the hydraulic water pump. It has good protection and good use effect.

[0022] 3. The blocking parts in this solution are detachable. When the pumping environment is good and there are fewer impurities and garbage, the number of blocking parts on the fixed ring can be reduced, the blocking area can be reduced, and the pumping rate can be increased. When the pumping environment is poor and there are more impurities and garbage, the number of blocking parts on the fixed ring can be increased to increase the blocking area, thereby better protecting the hydraulic water pump. It is highly flexible and can be adjusted according to needs. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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.

[0034] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indications will also change accordingly.

[0035] In addition, if the embodiments of the present invention include descriptions of "first," "second," etc., such descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of the technical features indicated. Therefore, features specified as "first" or "second" may explicitly or implicitly include at least one of such features.

[0036] See also Figure 1-8 A hydraulic water pump includes a water pump housing 1, a hydraulic motor 2, a water inlet 3 and a water outlet 4, and also includes: an impeller 5, which is arranged in the water pump housing 1 and connected to the hydraulic motor 2 through a shaft; a wear-resistant sealing ring 6, which is arranged on the inner wall of the water pump housing 1, and is located between the inner wall of the water pump housing 1 and the outer wall of the impeller 5; the impeller 5 includes an outer shell 51, impellers 52, an inlet 53 and a side outlet 54, the inlet 53 and the side outlet 54 are respectively arranged at the bottom and the side of the outer shell 51, and the impeller 52 is arranged on the inner wall of the outer shell 51.

[0037] The hydraulic water pump in this application differs from existing hydraulic water pumps in that an improved impeller 5 is provided inside the water pump housing 1, as well as an additional wear-resistant sealing ring 6. During use, the hydraulic motor 2 is started, driving the impeller 5 to rotate. The impeller 5's housing 51, impeller blades 52, inlet 53, and side outlet 54 all rotate as a whole. External water enters through the hydraulic water pump's water inlet 3, then enters the impeller 5 from the inlet 53, and is then discharged from the side outlet 54 along the impeller blades 52 before being pumped out through the water outlet 4 of the water pump housing 1. During this process, the outer shell 51 of the impeller 5 rotates closely against the wear-resistant sealing ring 6, but the outer shell 51 and the wear-resistant sealing ring 6 do not contact each other, and the gap between them is very small; and the water flow will be guided by the impeller 5, so that the water flow will be discharged into the water pump casing 1 along the inlet 53, the blades 52, and the side outlet 54 of the impeller 5. The cooperation of the outer shell 51 of the impeller 5 and the wear-resistant sealing ring 6 can greatly reduce the situation where the water flow is guided between the impeller and the inner wall of the water pump as in the existing method, so that the wear-resistant sealing ring 6 can play a good sealing and protection role, and avoids the situation where the impeller 5 directly closes to the inner wall of the water pump casing 1, greatly reducing the wear of the impeller 5 and the inner wall of the water pump casing 1, and improving its service life; the coordinated use of the impeller 5 and the wear-resistant sealing ring 6 can ensure the long-term and effective use of the hydraulic water pump, with high pumping efficiency and good pumping effect. After a long period of use, the wear-resistant sealing ring 6 can be replaced by disassembling the hydraulic water pump, and generally there is no need to repair or replace the impeller 5 and the water pump housing 1, which greatly reduces the cost of use, is highly practical, and can be widely used.

[0038] In this embodiment, preferably, please refer to Figure 2-4 A drainage channel 7 is provided inside the water pump housing 1. The water inlet 3 and the water outlet 4 are both connected to the drainage channel 7. The inlet 53 and the side outlet 54 of the impeller 5 are also connected to the drainage channel 7. External water flows in through the water inlet 3, then enters through the inlet 53 of the impeller 5, and then flows into the drainage channel 7 from the side outlet 54. Finally, the water in the drainage channel 7 is discharged through the water outlet 4.

[0039] In this embodiment, preferably, please refer to Figure 1 and Figure 6-7 A filter retaining frame 8 is also provided at the bottom of the water pump housing 1. The filter retaining frame 8 includes: a fixing ring 81, which is provided at the bottom of the water pump housing 1 and is provided with two. The two fixing rings 81 are connected by a plurality of connecting plates 82; and a blocking member 83, which is detachably provided between the two fixing rings 81. When the hydraulic water pump of the present application is used for pumping and draining water, the water will pass through the filter retaining frame 8 and enter the water inlet 3 of the hydraulic water pump, that is, enter after passing through the filter retaining frame 8. The filter retaining frame 8 can perform preliminary filtration on the water. Through the cooperation of the fixing ring 81, the connecting plate 82 and the blocking member 83, larger impurities and garbage in the water can be prevented from entering the hydraulic water pump, which can greatly prevent the hydraulic water pump from being blocked and damaged. The protective performance is good and the use effect is good.

[0040] The blocking member 83 is detachable. When the pumping environment is good and there is less impurities and garbage, the number of blocking members 83 on the fixed ring 81 can be reduced, that is, the blocking area can be reduced, thereby increasing the pumping rate and improving the pumping effect; and when the pumping environment is poor and there is more impurities and garbage, the number of blocking members 83 on the fixed ring 81 can be increased, which can increase the blocking area and restrict the entry of more garbage and impurities, thereby better protecting the hydraulic water pump and improving the quality of pumping. It is highly flexible and can be adjusted according to needs.

[0041] In this embodiment, preferably, please refer to Figure 6-7 The fixing ring 81 is provided with a plurality of mounting holes 9 in a circular shape. The blocking member 83 includes a connecting rod 831, with retractable mounting rods 832 provided at both ends. The mounting rods 832 fit into the mounting holes 9. The mounting rods 832 can be pressed to retract toward the connecting rod 831, shortening the distance between the mounting rods 832 on either side. The mounting rods 832 are then placed into the corresponding mounting holes 9. When the mounting rods 832 are released, they return to their original positions and eventually enter the mounting holes 9, allowing the blocking member 83 to be installed between the fixing rings 81 on both sides. Disassembly is similarly simple and convenient, allowing the number of blocking members 83 to be adjusted as needed, making subsequent replacement easier.

[0042] In this embodiment, preferably, please refer to Figure 8 The interior of the mounting rod 832 is provided with a connection to the inner recessed cavity 10, and the connecting rod 831 is slidably connected to the inner wall of the inner recessed cavity 10. An elastic member 11 is provided between the end of the connecting rod 831 and the inner wall of the inner recessed cavity 10. The elastic member 11 in this application is a spring. When the mounting rod 832 is pressed, it slides along the connecting rod 831, and the mounting rods 832 on both sides approach each other, compressing the elastic member 11. When the mounting rod 832 is subsequently released, the rebound force of the elastic member 11 drives the mounting rod 832 to move outward along the connecting rod 831, and finally returns to its original position.

[0043] In this embodiment, preferably, please refer to Figure 6-7 , the inner side wall of the connecting plate 82 is provided with a plurality of retaining rings 12. The setting of the retaining rings 12 can further increase the blocking effect of garbage impurities, reduce the area that can pass through, and have a good protective effect.

[0044] In this embodiment, preferably, please refer to Figure 6-8The retaining ring 12 is provided with a plurality of limiting holes, and the connecting rod 831 is provided with screw holes 13 that match the limiting holes. After the filter retaining frame 8 is installed, the screw holes 13 on the connecting rod 831 are aligned with the limiting holes on the retaining ring 12. Then, by screwing the bolts into the screw holes 13 and then inserting them into the limiting holes on the retaining ring 12, the position of the connecting rod 831 and the filter retaining frame 8 can be further fixed, which can greatly prevent the filter retaining frame 8 from becoming unstable and falling out during subsequent use.
