Description

Technical Field

[0001] This utility model relates to the field of leakage current detection, and in particular to a ground nail for leakage current detection and early warning. Background Technology

[0002] Currently, many municipal electrical devices in cities, such as traffic lights, streetlights, and distribution cabinets, lack suitable leakage current detection and early warning devices. While these devices rarely experience leakage under normal circumstances, they are prone to leakage during natural disasters, such as prolonged rainfall leading to flooding of city streets. The lack of a readily apparent leakage detection and early warning device makes these leaks difficult to detect, greatly increasing the risk of personal injury accidents, as evidenced by numerous news reports. Therefore, it is necessary to design an early warning device that can directly detect leakage in these electrical devices. Utility Model Content

[0003] The present invention aims to at least solve one of the technical problems existing in the prior art. Therefore, one objective of the present invention is to provide a ground nail for leakage current detection and early warning.

[0004] The technical solution of this utility model is as follows: A leakage current detection and early warning ground nail, characterized in that it includes: a metal rod and a detector disposed on the metal rod, the detector including a housing, a pulse sensor, a main controller, a detection switch and an alarm, the housing being an insulating housing connected to the metal rod, the detection switch being disposed on the housing, and the pulse sensor, the main controller and the alarm being encapsulated inside the housing, wherein the pulse sensor is connected to the metal rod, and the detection switch, the alarm and the pulse sensor are all connected to the main controller.

[0005] Furthermore, the lower end of the metal rod is a sharp conical end, and the upper end of the metal rod is provided with the detector.

[0006] Furthermore, the housing includes a base, a transparent cover, and a top cover. The base is fixedly fitted onto the metal rod. The transparent cover is located on top of the base with an insulating pad between them. The top cover is located on top of the transparent cover and has the detection switch on it.

[0007] Furthermore, the alarm includes a warning light and a buzzer.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0009] This device can be plugged into the ground next to equipment such as streetlights and power distribution cabinets that need to be tested for leakage. When these devices leak electricity, the electromagnetic pulse generated by the alternating current will be detected by the pulse sensor. After the pulse sensor transmits the signal to the main controller, the main controller can control the alarm to sound an alarm, which can intuitively remind passers-by of the danger of leakage.

[0010] This device has a simple structure, is easy to manufacture and process, is convenient to use, and is highly practical.

[0011] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0022] like Figures 1-4 The ground nail for leakage current detection and early warning shown includes: a metal rod 1 and a detector disposed on the metal rod 1.

[0023] like Figure 3 and Figure 4 As shown, the detector includes a housing 2, a pulse sensor 3, a main controller 4, a detection switch 5, and an alarm. The housing 2 is an insulating housing 2 and is connected to a metal rod 1. The detection switch 5 is provided on the housing 2. The pulse sensor 3, the main controller 4, and the alarm are encapsulated inside the housing 2. The pulse sensor 3 is connected to the metal rod 1, and the detection switch 5, the alarm, and the pulse sensor 3 are all connected to the main controller 4.

[0024] In specific settings, such as Figure 1 and Figure 2 As shown, the upper end of the metal rod 1 is equipped with a detector, and the lower end of the metal rod 1 is a sharp conical end, which facilitates insertion into the ground.

[0025] like Figure 3 As shown, the housing 2 includes a base 8, a transparent cover 9 and a top cover 10. The base 8 is fixedly fitted onto the metal rod 1, and the transparent cover 9 is located on top of the base 8 with an insulating pad 11 between them, thereby ensuring the insulation of the housing 2.

[0026] The top cover 10 is located on top of the transparent cover 9. The top cover 10 is equipped with a detection switch 5. The alarm includes a warning light 6 and a buzzer 7. The warning light 6 can flash light to sound an alarm, and the buzzer 7 can sound an alarm. Therefore, this device can achieve dual alarms of sound and light, thus having a good warning effect and effectively and intuitively reminding passersby of the danger of electric leakage.

[0027] The pulse sensor 3 used in this device is an existing product, such as the Pearson 150 type, STK-PL series, etc. Pulse sensors 3 can be selected according to the needs of those skilled in the art. The main controller 4 used can be, for example, a microcontroller.

After the metal rod 1 of the warning nail is inserted into the ground, the detection switch 5 is turned on. Since the current used in cities is mostly alternating current, when these devices leak current, the electromagnetic pulse generated by the alternating current will be detected by the pulse sensor 3. The pulse sensor 3 transmits the signal to the main controller 4, which can then control the alarm to sound an alarm, visually alerting passersby to the danger of leakage.

[0029] Although some embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations to these embodiments without departing from the principles and spirit of the present invention are all within the scope of protection of the claims of the present invention.
