[0002] Water pumps play an extremely important role in many fields of daily life, and there are differences in the structural design of water pumps according to different application scenarios and usage purposes. For example, in large hydraulic projects, multiple water pumps are usually connected in parallel, and the total pipeline is used to achieve water inlet and outlet. The multiple parallel water pumps can be set with different flow or pressure parameters to meet the actual usage requirements.

For example, in some remote areas or mountainous areas, there are requirements for the stability of water pump use. Although the method of using the total pipeline and multiple parallel water pumps can meet the stability requirements, the engineering quantity is large and it will have an impact on the environment when implemented, and it is not easy to maintain after installation; therefore, a water pump that is easy to use stably in special environments is needed.

[0023] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only the parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0024] For different scenarios and purposes of water pump use, existing water pumps can be designed with a structure of multiple pumps in parallel, using a main pipeline for water supply, and the water pumps can be set with different flow or pressure parameters to meet actual usage requirements. However, the above implementation method involves a large amount of engineering work for remote areas or mountainous regions, causing environmental impacts and being difficult for later maintenance. Therefore, a water pump that is easy to use stably in special environments is needed.

[0025] Embodiment 1

[0026] In view of the above deficiencies, the present utility model proposes a linkage control water pump, as Figure 1 , Figure 2 and Figure 3 shown, including:

[0027] A water pump unit 1, including at least two water pumps 2 and motor drive modules 3 corresponding to the water pumps 2 one by one; the number of water pumps 2 can be preset according to actual situations, and the operation of individual water supply can be realized, and the corresponding pump head connecting pipes 7 need to be correspondingly adapted; communication cables 4 are connected between the motor drive modules 3; the inner side of the housing of the water pump 2 is in a volute shape; the pump head water outlet 6 and the pump body water inlet 9 are respectively connected inside the housing.

[0028] Among them, the motor drive module 3 is further divided into a motor sub-module 10 and a drive sub-module 11;

[0029] The motor sub-module 10 is electrically connected to the drive sub-module 11, and an impeller is connected to the output end of the motor sub-module 10, and the impeller extends to the inner side of the housing. The drive sub-module 11 realizes the transportation of the water supply from the pump head water outlet 6 and the pump body water inlet 9 to the target carrier, such as an external reservoir, by driving the impeller to rotate.

[0030] Since both the motor sub-module 10 and the drive sub-module 11 need to be powered, both are connected to an external power supply through a power connection line 12, and this external power supply includes but is not limited to batteries, mains electricity, etc. In addition, the drive sub-module 11 is connected to an external terminal through a signal connection line 13, and its function is to load a program into the drive sub-module 11, and as a preferred implementation method, the working state of the water pump 2 can also be obtained in real time through continuous connection. Correspondingly, the drive sub-module 11 can set the working state of the water pump 2 according to the program, such as all working, or partial working, or alternating working, etc. As a preferred implementation method, communication cables 4 are connected between the drive sub-modules 11 corresponding to different water pumps 2, so that the priority order can be adjusted.

[0031] An outlet unit 5, including a pump head water outlet 6 communicating with the water pump 2; the size of the pump head water outlet 6 needs to meet the maximum flow requirement during the water supply circulation inside the volute.

[0032] The water inlet unit 8 includes a pump body water inlet 9 communicating with the water pump 2 and a pump head connecting pipe 7 connecting the pump body water inlet 9 with the water pump 2. The pump head connecting pipe 7 can collect the external water supply into the volute inside the housing of the water pump 2, but the water pump 2 can only achieve the flow of the water supply under the action of the motor drive module 3. The pump head water outlet 6 and the pump body water inlet 9 are tightly connected to the external water pipes. For example, they can be set in the structure of a flange and configured with rubber rings for sealing.

[0033] A linkage control water pump provided by an embodiment of the present invention can control the working modes of multiple water pumps by arranging at least two water pumps in parallel and sharing the pump head water outlets and pump body water inlets of the water pumps, and by setting communication cables between the motor drive modules corresponding to the water pumps. Moreover, when a certain water pump fails, it can ensure that other water pumps can complete the replacement work, so as to meet the need for stable use in special environments.

[0034] Embodiment 2

[0035] Based on Embodiment 1, an embodiment of the present invention provides a linkage control water pump in a main and second water pump mode. Specifically, the water pump unit 1 includes a first water pump and a second water pump;

[0036] The first water pump is connected to the first motor drive module, and the second water pump is connected to the second motor drive module. The first motor drive module is connected with an alarm module 14. When the motor drive module 3 loads the program through an external terminal, the functions of the first water pump and the second water pump are distinguished. During the use process, it is preferably operated as a water injection pump. When the water injection pump or its corresponding first motor drive module fails, the main drive module can give a warning through the alarm module 14, such as an alarm, and automatically switch to the second water pump and the second motor drive module for work, so as to ensure the normal operation of the linkage control water pump.

Moreover, the first feature being "above", "over" and "on" the second feature includes that the first feature is directly above and obliquely above the second feature, or merely indicates that the horizontal height of the first feature is higher than that of the second feature. The first feature being "under", "beneath" and "underneath" the second feature includes that the first feature is directly below and obliquely below the second feature, or merely indicates that the horizontal height of the first feature is lower than that of the second feature.
