[0002] Existing water pumps typically have high power consumption and low head. When the pumping volume is insufficient, the motor continues to rotate at high speed, consuming a large amount of electrical energy. Therefore, variable frequency drives (VFDs) are usually used. Existing large VFDs can simultaneously regulate multiple pumps connected in parallel. However, VFDs are usually fixed in structure, making them inconvenient to move and use outdoors, posing significant inconvenience in short- to medium-term outdoor environments. To address these issues, an outdoor mobile VFD has been invented. Summary of the Invention

[0016] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

They are used only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0018] 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 indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified. Furthermore, the terms "installed," "connected," and "linked" should be interpreted broadly; for example, they may refer to a fixed connection, a detachable connection, or an integral connection; they may refer to a mechanical connection or an electrical connection; they may refer to a direct connection or an indirect connection through an intermediate medium; and they may refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0019] Please see Figure 1-2 The present invention provides an outdoor mobile variable frequency energy-saving water pump controller, which includes a cabinet 3 and a base 9.

[0020] The inverter controller body 6 is fixedly installed inside the cabinet 3, and several sets of power leads 7 are arranged below the inverter controller body 6.

[0021] The power lead 7 is electrically connected to the inverter controller body 6. Universal casters 5 are fixedly installed on the outer bottom of the base 9.

[0022] The base 9 has a battery 8 installed inside, and the top of the cabinet 3 has a solar panel 1 installed. The solar panel 1 is electrically connected to the battery 8 and the inverter controller body 6.

[0023] Specifically, a ventilation opening 10 is provided on the top of the cabinet 3, and a dust filter 11 is provided on the inner side of the ventilation opening 10, and the ventilation opening 10 is located below the solar panel 1.

[0024] A vent 10 is provided below the solar panel 1. During the use of the device, it can not only heat up the frequency converter, but also work with the dust filter 11 to effectively reduce the entry of external dust into the device. The solar panel 1 above provides good shading, and in outdoor environments, it can convert solar radiation energy into electrical energy and store it in the battery 8 to power the device, thus improving the device's practicality.

[0025] The cabinet body 3 and the base 9 are an integrated structure and are made of 316 stainless steel.

[0026] The power leads 7 are evenly distributed below the inverter controller body 6, and the power leads 6 are fixed in the cabinet by fixing clips; the longer power leads facilitate the connection between the device and the water pump; multiple power leads also facilitate the simultaneous connection and use of multiple water pumps.

[0027] The omnidirectional caster 5 is made of industrial heavy-duty iron core PU wheel material and has a brake wheel. It is fixed to the outside of the base 9 by four stainless steel bolts through a fixed bracket.

[0028] The device is equipped with multiple power leads 7 located below the inverter controller body 6. During the use of the device, simply open the lower front cover 4 of the cabinet to take out the connecting wires and connect them to the required water pump. The inverter controller body does not need to be in direct contact with the outside. At the same time, the long power leads can be easily connected to multiple water pumps that are temporarily set up.

[0029] Working principle: When using this variable frequency energy-saving water pump controller, according to... Figure 1-2 As shown, open the lower front cover 4 of the cabinet to take out the power lead 7 and connect it to the corresponding water pump. Then, the DB3610 inverter controller body 6 can be set and adjusted by opening the upper front cover 2 of the cabinet. The solar panel 1 on the top of the device can convert solar radiation energy into electrical energy to provide power for the inverter control. It can also be stored in the battery 8 so that on cloudy days when there is no solar energy, it can be converted into electrical energy to provide power for the water pump for a period of time. At the same time, it can also provide good shading for the device body below, preventing the device from being exposed to the sun and affecting the normal use of the device. During the use of the device, when moving the outward casters to move the device to the required position, the brake casters are used to fix the device to prevent the device from moving randomly and interfering with the normal use of the water pump.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
