Description

Technical Field

[0001] The present application relates to the technical field of water pumps, and in particular to a lightweight water pump. Background Art

[0002] At present, water pumps are important equipment for disaster relief. When in use, the entire unit of the water pump needs to be submerged in water to pump out the accumulated water by using the water pump and the water hose.

[0003] Traditional disaster relief water pumps include a motor barrel and a water outlet module with an impeller and a guide vane arranged inside. A support mechanism is arranged between the motor barrel and the water outlet module. One end of the support structure is detachably connected to the motor barrel through a flange and bolts, and the other end of the support structure is detachably connected to the water outlet module through a flange and bolts. Since the two flanges need to match the sizes of the cross-sections of the motor barrel and the water outlet module respectively, the sizes and masses of the two flanges will be relatively large, resulting in a relatively large overall mass of the water pump.

[0004] During actual operation, the staff needs to manually transport the water pump to the designated position for operation. In the critical period of disaster relief, time is of the essence. The relatively heavy water pump is not convenient for the staff to transport it to the designated position, affecting the efficiency of disaster relief, and there is room for improvement. Utility Model Content

[0005] In order to reduce the mass of the water pump and improve the working efficiency of disaster relief, the present application provides a lightweight water pump.

[0006] The lightweight water pump provided by the present application adopts the following technical solutions:

[0007] A lightweight water pump includes a motor barrel and a water outlet module. A plurality of support structures are arranged in an array between the motor barrel and the water outlet module. The support structures are arranged with a reduced diameter along the direction from the motor barrel to the water outlet module. An inlet space is formed between the support structures and the water outlet module. The upper end of the support structure is detachably connected to the water outlet module. The diameter of the water outlet module is larger than that of the motor barrel. The lower end of the support structure is integrally formed with the motor barrel.

[0008] By adopting the above technical solutions, the upper end of the support structure is detachably connected to the water outlet module, and the lower end of the support structure is integrally formed with the motor barrel. Then, it is possible to realize the connection between the motor barrel and the water outlet module without using the traditional two flanges. Moreover, the support structures are arranged with a reduced diameter along the direction from the water outlet module to the motor barrel, making the water pump compact, lightweight, and thus facilitating the staff to transport the water pump and improving the working efficiency.

[0009] Preferably, a connecting member is commonly arranged between adjacent support structures, and the connecting member is detachably connected to the water outlet module.

[0010] By adopting the above technical solution, connecting parts are set between adjacent supporting structures, which increases the connection area between the supporting structure and the water outlet module, thereby increasing the connection strength between the motor barrel and the water outlet module, making the connection between the motor barrel and the water outlet module more stable, and forming a detachable connection with the water outlet module by using the connecting parts, which facilitates the staff to disassemble and install the water outlet module as needed.

[0011] Preferably, a fixing bolt is provided on the connecting member, and the fixing bolt passes through the connecting member along the direction of the motor barrel pointing to the water outlet module and forms a threaded connection with the water outlet module.

[0012] By adopting the above technical solution, a connecting piece is passed through the motor barrel in the direction of the water outlet module using a fixing bolt and a threaded connection is formed with the water outlet module. When the water outlet module is disassembled after completing the underwater operation, since the motor barrel is placed on a horizontal ground, water stains in the bolt hole will drip naturally due to gravity, thereby reducing the possibility of rust on the fixing bolt during use.

[0013] Preferably, a first weight-reducing groove is provided on a side of the support structure facing away from the motor cylinder.

[0014] By adopting the above technical solution and utilizing the provision of the first weight-reducing groove, the weight of the support frame is reduced, thereby reducing the overall weight of the water pump.

[0015] Preferably, a second weight-reducing groove is provided on a side of the support structure away from the first weight-reducing groove.

[0016] By adopting the above technical solution and utilizing the provision of the second weight-reducing groove, the weight of the support frame is reduced, thereby reducing the overall weight of the water pump.

[0017] Preferably, a third weight-reducing groove is provided on the connecting member.

[0018] By adopting the above technical solution and utilizing the provision of the third weight-reducing groove, the weight of the connecting piece is reduced, making the connecting piece lighter and easier to disassemble and install.

[0019] Preferably, a guide member for guiding water flow into the water outlet module is provided in the water inlet space, and the guide member is detachably connected to the motor barrel.

[0020] By adopting the above technical solution and utilizing the setting of the guide member, it is convenient to guide the water flow into the water inlet space and then into the water outlet module, thereby improving the working efficiency.

[0021] Preferably, a fourth weight-reducing groove is provided on the guide member.

[0022] By adopting the above technical solution, the weight of the guide member is reduced by the provision of the fourth weight-reducing groove, and further the overall weight of the water pump is reduced, thus facilitating the handling of the water pump by the staff.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. By forming a detachable connection between the upper end of the support structure and the water outlet module, and fixedly connecting the lower end of the support structure to the motor cylinder, the connection between the motor cylinder and the water outlet module can be achieved without using two traditional flanges, making the water pump compact and lightweight, thus facilitating the transportation of the water pump by the staff and improving work efficiency;

[0025] 2. By arranging the connecting member between adjacent support structures, the connection area between the support structure and the water outlet module is increased, thereby increasing the connection strength between the motor cylinder and the water outlet module, making the connection between the motor cylinder and the water outlet module more stable, and forming a detachable connection between the connecting member and the water outlet module, facilitating the staff to disassemble and install the water outlet module as needed;

[0026] 3. By the provision of the first weight-reducing groove, the second weight-reducing groove, the third weight-reducing groove and the fourth weight-reducing groove, the overall weight of the water pump is reduced, thus facilitating the handling and transportation of the water pump by the staff.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0030] The following will further describe the present application in detail Figure 1 - with reference to the Figure 2 drawings.

[0031] The embodiment of the present application discloses a lightweight water pump.

[0032] Refer to Figure 1, A lightweight water pump, comprising a motor cylinder 1 and a water outlet module 2. An intake space 3 is formed between the motor cylinder 1 and the water outlet module 2. The diameter of the water outlet module 2 is larger than that of the motor cylinder 1. A plurality of support structures 4 are arranged in an array between the motor cylinder 1 and the water outlet module 2. In this embodiment, three support structures 4 are provided. The upper end of any one of the support structures 4 is detachably connected to the water outlet module 2, and the lower end of any one of the support structures 4 is fixedly connected to the motor cylinder 1. Thus, the connection between the motor cylinder 1 and the water outlet module 2 can be realized without using the traditional two flanges, making the water pump compact and lightweight, which is convenient for the staff to transport the water pump and improves work efficiency.

[0033] Referring to Figure 1 , since the structures and connection methods of the three support structures 4 are the same, one of the support structures 4 will be taken as an example for elaboration.

[0034] Referring to Figure 1 , the support structure 4 is set as a support frame 41. The support frames 41 are arranged in a circumferential array with the axis of the output shaft of the motor cylinder 1 as the axis. The lower end of the support frame 41 is integrally formed on the surface edge of the motor cylinder 1 close to the water outlet module 2. The support frame 41 is arranged with a reduced diameter along the direction from the motor cylinder 1 to the water outlet module 2 of the motor cylinder 1, so that when the support structure 4 bears the pressure of the water outlet module 2, these forces can be better dispersed and transmitted, thus forming a more stable support system between the motor cylinder 1 and the water outlet module 2, and further enhancing the stability and durability of the entire water pump structure.

[0035] Referring to Figure 1 and Figure 2 , a first weight-reducing groove 411 is formed at one end of the support frame 41 away from the axis of the motor cylinder 1. The first weight-reducing groove 411 is hook-shaped and the opening is inclined in the direction away from the axis of the motor cylinder 1. A second weight-reducing groove 412 is arranged on the side of the support frame 41 opposite to the first weight-reducing groove 411. By using the settings of the first weight-reducing groove 411 and the second weight-reducing groove 412, the weight of the support frame 41 is reduced, and thus the overall weight of the water pump is reduced.

[0036] Referring to Figure 2, the upper ends of the three support frames 41 are jointly welded with a connecting member 5. The connecting member 5 is detachably connected to the water outlet module 2, thereby increasing the connection area between the support frame 41 and the water outlet module 2, and further increasing the connection strength between the motor cylinder 1 and the water outlet module 2, making the connection between the motor cylinder 1 and the water outlet module 2 more stable. The connecting member 5 is arranged in a circular ring shape. The diameter of the connecting member 5 is the same as the diameter of the lower surface of the water outlet module 2. The diameter of the connecting member 5 is larger than the diameter of the motor cylinder 1. The connecting member 5 is coaxially arranged with the water outlet module 2 and the motor cylinder 1. Bolt holes 51 and fixing bolts 52 are arranged in a circumferential array on the connecting member 5. Both the bolt holes 51 and the fixing bolts 52 are provided with six. Any fixing bolt 52 passes through the bolt hole 51 in the direction from the motor cylinder 1 to the water outlet module 2 and is threadedly connected to the water outlet module 2, which facilitates the staff to disassemble and install the water outlet module 2 as needed. At the same time, after the water outlet module 2 is disassembled after completing underwater operations, since the motor cylinder 1 is placed on the horizontal ground, the water stains in the bolt holes 51 will naturally drip under the influence of gravity, reducing the possibility of the fixing bolts 52 rusting during use.

[0037] Refer to Figure 2 , third weight-reducing grooves 53 are arranged in a circumferential array along the axis of the motor cylinder 1 on the connecting member 5. There are six third weight-reducing grooves 53. The arrangement of the third weight-reducing grooves 53 reduces the weight of the connecting member 5, making the connecting member 5 lighter and more convenient for disassembly and installation.

[0038] Refer to Figure 1 , a guiding member 31 for guiding water flow into the water outlet module 2 is detachably arranged in the water pump in the water inlet space 3. The guiding member 31 is threadedly connected to the motor cylinder 1 through bolts. The guiding member 31 is arranged in a frustum shape. By using the guiding surface with a narrow upper part and a wide lower part on the guiding member 31, it is convenient for the guiding member 31 to guide the water flow into the water inlet space 3 and then into the water outlet module 2, improving the working efficiency.

[0039] Refer to Figure 1 , fourth weight-reducing grooves 311 are arranged on the guiding member 31, reducing the weight of the guiding member 31 and further reducing the overall weight of the water pump, thereby facilitating the staff to carry the water pump and improving the working efficiency.

[0040] The implementation principle of the embodiment of the present application is as follows: Since the connecting member 5 on the support frame 41 is threadedly connected to the water outlet module 2 through the fixing bolts 52, and the lower end of the support frame 41 is welded or integrally formed with the motor cylinder 1, it is possible to realize the connection between the motor cylinder 1 and the water outlet module 2 without using two traditional flanges with larger masses. At the same time, combined with the arrangement of multiple weight-reducing grooves, the water pump is more compact and lightweight, thus facilitating the staff to transport the water pump and improving the working efficiency.

[0041] The above are all preferred embodiments of the present application, and do not limit the protection scope of the present application. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
