[0002] The field of drainage rescue is very broad. Usually, one type of drainage pump can only adapt to one drainage condition. Different drainage pumps are required for different drainage conditions. In order to cope with different drainage conditions, multiple types of drainage pumps need to be prepared, which causes great inconvenience to rescue use.

[0003] Although there is also a method in the related art to change the function of the water pump by replacing the hydraulic model to adapt to different working conditions, however, the existing solution has the defect of too many replacement parts. For example, the utility model patent with authorization announcement number CN209943124U records that the high-lift water pump in the multi-purpose drainage rescue pump needs to set a transition plate between the guide vane body and the water inlet section to fix the sealing ring, while the large-flow water pump does not need a transition plate. As a result, when replacing it, it is necessary to replace or carry an additional transition plate, which increases the difficulty of replacement and requires carrying an additional transition plate.

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0029] The inventor of the utility model has considered that a sealing structure needs to be provided in a high-lift water pump to seal the gap between the impeller and the guide vane body. The sealing structure is usually provided at the lower part of the impeller, and the gap between the lower part of the impeller and the guide vane body is relatively large. Therefore, a sealing ring and a transition plate are required to be used for sealing at the same time. The outer end of the transition plate is fixedly clamped between the water inlet section and the guide vane body, and the inner end is fixed with a sealing ring, and the inner end of the sealing ring is in sliding contact with the impeller. This achieves sealing without affecting the rotation of the impeller. However, water pumps with other functions, such as large-flow water pumps, usually do not need to be provided with a sealing structure. Therefore, when the hydraulic models of the two are interchanged, the disassembly, installation and carrying process of the sealing structure need to be considered. Based on this, the inventor of the utility model provides the following multiple embodiments to overcome the above-mentioned defects.

[0030] Embodiment 1

[0031] The utility model embodiment provides a high-lift hydraulic model, such as Figure 3 to Figure 5 As shown, it includes an impeller 21 and a guide vane body 22. The impeller 21 is arranged in the guide vane body 22. A sealing ring 7 is arranged between the top of the impeller 21 and the inner wall of the guide vane body 22. The inner side of the sealing ring 7 contacts the impeller 21, and the outer side contacts the guide vane body 22.

[0032] Specifically, the sealing ring 7 is fixedly connected to the inner wall of the guide vane body 22 by screws, and the sealing ring 7 can also be fixed by other means, such as clamping.

[0033] In other embodiments, the sealing ring 7 may also be fixed to the outer side of the upper portion of the impeller 21 by bolts or other connection methods.

[0034] The sealing ring 7 in the high-lift hydraulic model provided in the embodiment of the utility model is arranged between the top of the impeller 21 and the inner wall of the guide vane body 22, which eliminates the need for a transition plate. When the hydraulic model is replaced, there is no need to remove and install the transition plate, thereby improving the replacement efficiency of the hydraulic model and providing portability.

[0035] Embodiment 2

[0040] The pumping characteristics of the multiple hydraulic models are not exactly the same, that is, the functions are different, such as large head, large flow, etc.

[0041] The multiple hydraulic models in the water pump group with replaceable hydraulic models in the embodiment of the utility model can all be installed on the motor module 1, which can realize the replacement of the hydraulic model by assembling the hydraulic models with different functions on the same motor module 1 respectively, thereby adapting to different usage environments. Moreover, since at least one hydraulic model in the water pump group is the high-lift hydraulic model described in embodiment 1, it also has the characteristics of high replacement efficiency and portability.

[0042] Specifically, the hydraulic model includes an impeller 21 and a guide vane body 22. Existing water pumps usually use bolts and impeller nuts 31 to install the impeller 21, and flanges and bolts to install the guide vane body 22. Therefore, in order to further reduce the amount of parts replacement, in some embodiments, each guide vane body 22 is assembled with the motor module 1 using the same connection assembly, and each impeller 21 is assembled with the motor shaft of the motor module 1 using the same connection assembly. This means that when the hydraulic model is replaced, there is no need to replace connection assemblies such as bolts and impeller nuts 31, further improving portability and replaceability.

[0043] It can be understood that the diameters of the threaded holes or bolt holes on the flange of the guide vane body 22 corresponding to different functional hydraulic models in the above embodiment are the same, so as to achieve the purpose of assembling the guide vane body 22 and the motor module 1 with the same batch of bolts.

[0044] Similarly, each impeller 21 and the motor shaft of the motor module 1 are assembled using the same bolt and impeller nut 31, which requires that the structures on each impeller 21 that cooperate with the bolt and the impeller 21 nut have the same specific structure. The specific structure enables each impeller 21 to be installed using the same bolt and impeller nut 31. The specific structure can be a through hole for passing the bolt, and the diameter and length of the through hole are the specific structure.

The two flanges 6 form the installation part of the filter 8, and the top structure of the filter 8 is a hoop 81, which is hooped around the outer periphery of the two flanges 6.

[0047] That is, the thickness and size of the flange 6 at the bottom of any guide vane body 22 in the present invention are equal, so as to fix the same filter screen 8.

[0048] The embodiment of the utility model achieves the purpose of using the same filter 8 for water pumps with different functions. When going out in danger, the person in danger can carry only one filter 8 to achieve the universal purpose without carrying a large number of filters 8.

[0049] In some embodiments, the utility model further comprises a box body, in which a receiving cavity for receiving the hydraulic model is provided, and two receiving cavities are provided, and the shapes and sizes of the two receiving cavities are respectively the same as those of the impeller 21 and the guide vane body 22. This embodiment is more convenient for carrying the impeller 21 and the guide vane body 22 separately.

[0050] Specifically, the accommodating cavity may be formed in the foam or in the plastic shell, and the accommodating cavity is used to limit the impeller 21 and the guide vane body 22 to prevent the impeller 21 and the guide vane body 22 from being damaged due to vibration transition during transportation.
