[0019] To make the objectives, technical solutions, and advantages of the present invention more clearly understood, the present invention is further described below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are merely illustrative and are not intended to limit the scope of the present invention. Furthermore, descriptions of known structures and technologies are omitted in the following description to avoid unnecessary confusion regarding the concepts of the present invention.

[0020] It should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer" used in this application document to indicate positions or locations are based on the positions or locations shown in the accompanying drawings and are intended solely to facilitate and simplify the description of this disclosure. They are not intended to indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this disclosure. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0021] Combine Figures 1 to 3 As shown, an electric-to-water metering terminal includes a base 1 with a top-opening retaining slot 10 in the middle. A current transformer 2 is located within retaining slot 10, which includes a wire hole 21. Current transformer 2 is a split-type current transformer with a snap-on clip on one side. Current transformer 2 is electrically connected to a power module 4 and a communication module 3, which is wirelessly connected to a remote monitoring terminal 9.

[0022] The upper parts of both ends of the bottom shell 1 are respectively provided with upper covers 5, and two groups of upper covers 5 are symmetrically arranged at both ends of the mutual inductor 2. The ends of the upper covers 5 connected to the mutual inductor 2 are respectively provided with pressing tongues 51, and the pressing tongues 51 are crimped into the bottom wall of the wire hole 21. The power module 4 and the communication module 3 are respectively arranged on the lower sides of both ends of the wire hole 21. The power module 4 and the communication module 3 are respectively arranged in the cavities at both ends of the bottom shell 1, and the two groups of upper covers 5 are respectively covered on the upper parts of the cavities at both ends of the bottom shell 1. The upper parts of the upper covers 5 are respectively provided with wire pressing grooves 50, and the wire hole 21 is coaxially arranged with the two groups of wire pressing grooves 50. The top of the bottom shell 1 is provided with a shield 6, and the shield 6 is crimped onto the upper parts of the two groups of wire pressing grooves 50.

[0023] When used, combine Figures 1 to 5 As shown, the wire hole 21 of the transformer 2 is used to pass through the single power line of the water pump 7. The transformer 2 is set between the control box 8 of the original pumping system and the water pump 7. The power line is fixed by the protective cover 6 and the wire groove 50, and the transformer 2 is fixed at the same time by the tongue 51. The power module 4 provides operating power for the metering terminal; the communication module 3 records and forwards the current information sensed by the transformer 2. By detecting the presence or absence of current in the power line of the water pump 7, it is determined whether the water pump 7 is turned on or off. Since the flow rate of the water pump 7 per unit time is basically fixed, the drainage volume of the water pump 7 within the time period t can be converted by the duration t of the current sensed by the transformer 2. A timing module can also be set in the communication module 3, so that the drainage volume of the water pump 7 can be directly forwarded to the remote monitoring terminal 9 through the communication module 3.

[0024] It should be understood that the above-described specific embodiments of the present invention are merely illustrative of or explanation of the principles of the present invention and do not constitute limitations of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present invention shall be included within the scope of protection of the present invention.
