Description

Technical Field

[0001] This utility model relates to the field of electricity bill and price anomaly investigation technology, specifically an electricity bill and price anomaly investigation device. Background Technology

[0002] The clamp meter is a common tool used to troubleshoot abnormal electricity bills and prices. The clamp meter is used to measure the current and observe the flashing status of the meter's pulse light. If the flashing continues after the main switch is turned off, there may be an abnormality.

[0003] For example, the Chinese authorized patent with announcement number CN207248950U (A self-clamping current clamp meter) includes a clamp meter body, a controller mounted on the upper end of the clamp meter body, a fixed clamp shell and a rotating clamp shell mounted inside the clamp meter body via a fixed shaft, an electromagnet mounted on the inner wall of the clamp meter body, and a sliding groove provided on one side of the inner wall of the clamp meter body, with a sealing plate slidably mounted inside the sliding groove. The advantages are: the controller controls the electromagnet to be energized, attracting magnetic components through magnetic force, thereby driving the rotating clamp shell to rotate via the rotating plate, facilitating the placement of the wire to be tested between the fixed iron core and the rotating iron core; the controller controls the electromagnet to be de-energized, and under the elastic action of the return spring, the fixed iron core and the rotating iron core close to form a circuit, allowing for induced current detection through the clamp meter body, eliminating the need for manual opening and reducing the user's workload; the sealing spring drives the sealing plate to move inside the sliding groove, ensuring that the sealing plate is always in contact with the rotating clamp shell, guaranteeing a sealing effect.

[0004] Existing AI early warning models, such as those based on multi-source data like current, temperature, and vibration, and algorithms like the Isolation Forest algorithm, can predict faults up to 30 minutes in advance, reducing power outage losses and demonstrating high practical value.

[0005] For example, the Chinese authorized patent with announcement number CN117686757B (An intelligent early warning method and system for an outdoor power metering box) includes: identifying historical overheat protection monitoring data, generating a sample dataset of power protection triggers and labeling it based on the false touch power protection mode to obtain a labeled sample dataset, performing feature extraction to obtain a false touch feature set, obtaining a real-time abnormal dataset if an overheat protection command is triggered, inputting it into a false touch mode recognition model to calculate the first false touch probability, and generating a first early warning message when the first false touch probability reaches a preset false touch probability. This solves the technical problem that the existing technology has limitations and is not rigorous enough in judging false touches of overheat protection, resulting in insufficient judgment accuracy and affecting the operation status of the equipment. For real-time abnormal data, modeling is used to identify, match and comprehensively evaluate the false touch features to ensure the rigor of analysis and processing efficiency, accurately determine the false touch probability and issue an alarm to avoid invalid protection operations.

[0006] However, existing clamp meters used for checking abnormal electricity prices require multiple test leads and test lead leads to be stored separately from the clamp meter after use, making them difficult to carry as a whole and prone to loss. Therefore, they do not meet the current needs. To address this, we have proposed an electricity price anomaly checking device. Utility Model Content

[0007] The purpose of this utility model is to provide a device for investigating abnormal electricity charges, in order to solve the problem mentioned in the background art that the existing clamp meters used for investigating abnormal electricity charges require multiple test probes and test probe leads to be stored separately from the clamp meter after use, making them difficult to carry as a whole and prone to being lost.

[0008] To achieve the above objectives, this utility model provides the following technical solution: an electricity bill anomaly detection device, comprising: a clamp meter body, a clamp head provided at the top of the clamp meter body, a storage component provided at the rear end of the clamp meter body, test pen storage cavities provided on both rear surfaces of the clamp meter body, a display screen provided on the front surface of the clamp meter body, a control button provided at the lower end of the display screen, compression inner plates provided on both inner walls of both ends of the test pen storage cavity, and the compression inner plates are heat-fused to the inner walls of the test pen storage cavity, the storage component includes a central frame, a first crossbar provided at the front end of one end of the central frame, a second crossbar provided at the front end of the other end of the central frame, a carrying strap provided on one side of the clamp meter body, fixing screws provided at both ends of the carrying strap, and the carrying strap is fixed to the clamp meter body by the fixing screws.

[0009] Preferably, the rear surfaces at both ends of the center frame are provided with through holes, and the through holes pass through the center frame, the first cross frame and the second cross frame. A fixing bolt is inserted into one end of the through hole, and the other end of the fixing bolt passes through the through hole and is threadedly connected to the clamp meter body.

[0010] Preferably, wear-resistant sleeves are provided on the outer ends of both the first and second crossbars, and the wear-resistant sleeves are fitted on both ends of the first and second crossbars, and the wear-resistant sleeves are made of rubber material.

[0011] Preferably, a power button is provided on the other side of the clamp meter body, and a charging port is provided below the power button.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] (1) This utility model sets two test pen storage cavities on the rear surface of the clamp meter body and sets a storage component at the rear end of the clamp meter body. When storing the test pens after the inspection, the test pen wires are wrapped around the central frame and limited by the first and second cross frames to prevent them from falling off. After wrapping, the two test pens are respectively embedded into the two test pen storage cavities. The test pens are squeezed and fixed by the inner plate to prevent them from falling off. The test pens and clamp meter are stored as a whole, rather than separately. This improves the convenience of carrying and makes it less likely to be lost or misplaced. It solves the problem that the clamp meter used for checking abnormal electricity prices needs to store multiple test pens and test pen wires after use. It is not easy to carry as a whole and is prone to being lost. When the clamp meter is placed on the ground, it is supported by the first and second cross frames to prevent the clamp meter body from being damaged by friction with the ground. The first and second cross frames are in contact with the ground through wear-resistant sleeves, which are not easy to be damaged by friction and improve the service life.

[0014] (2) By setting a carrying strap on one side of the clamp meter body, the carrying strap is fixed to the clamp meter body by fixing screws, which is convenient for replacement. The carrying strap makes it easier for personnel to carry the clamp meter instead of simply holding the clamp meter body by hand, thus improving flexibility and convenience.
