Abstract
The utility model provides a prevent static ground connection circuit fault alarm device, including electromagnetic relay, bar copper, bee calling organ, red pilot lamp, green pilot lamp and power, whether normal reliable device of being connected between detecting earthing device and the needs earthing device through the line connection between relay and the earthing device, directly will need earthing device to be connected to during the use the utility model discloses alarm device can, if earthing device and the circuit that needs between the earthing device break down, alarm device can light red warning lamp automatically and switch-on bee calling organ begins to report to the police to the staff in time discovers that the earthing circuit breaks down and in time handles.
Description
Technical Field
The utility model relates to an equipment antistatic technical field especially relates to a prevent static ground connection fault alarm device.
Background
The anti-static grounding system can prevent a human body from being subjected to electric shock, equipment and lines from being damaged, prevent fire and lightning, prevent static damage and ensure normal operation of a power system, and is widely applied to the fields of electronics, semiconductors, petroleum industry, weapon industry, textile industry, rubber industry and military.
However, the conventional antistatic facilities only ensure connection between the grounding device (corresponding to a copper bar or the like) and the ground, and ignore reliable connection between the equipment which needs to be grounded and the grounding device (corresponding to a copper bar or the like). If a wire between the grounding device and the grounding device is required to be disconnected or the grounding device (equivalent to a copper bar and the like) is lost, the conventional grounding system can be completely failed to damage human bodies or equipment, and the conventional means cannot be used for effective detection.
Disclosure of Invention
The utility model aims at providing a prevent static earth connection circuit fault alarm device, when earthing device (being equivalent to bar copper etc.) and need connect the disconnection between the earthing device, automatic alarm to the staff in time discovers that the earth connection circuit breaks down and in time handles, has ensured the reliable connection between earthing device and the needs earthing device.
The utility model discloses a realize like this, a prevent static ground connection circuit fault alarm device, including electromagnetic relay, bar copper, bee calling organ, red pilot lamp, green pilot lamp, prevent static earth connection one end and connect electromagnetic relay's IN end, the other end is connected the one end of bar copper, the other end of bar copper is connected to electromagnetic relay's VCC end through the wire, forms and prevents static ground circuit; the copper rod is buried under the ground with the depth of 50 cm; the control end of the electromagnetic relay is connected with a buzzer and an indicator light; the normally closed contact of the electromagnetic relay is connected with a buzzer, the buzzer is connected with a red indicator light, and the red indicator light is connected with the common contact of the electromagnetic relay to form a loop; and a normally open contact and a common contact of the electromagnetic relay are respectively connected with two ends of the green indicating lamp to form a loop.
Wherein, the electromagnetic relay is also connected with a 5v power supply.
The electromagnetic relay is in the type of SRD-5 VCD-SL-C.
The utility model discloses whether alarm device is used for detecting reliably being connected between earthing device and the needs earthing equipment, directly will need earthing equipment to be connected to during the use the utility model discloses alarm device can, if earthing device and the circuit that needs between the earthing equipment broke down, alarm device can light red warning light automatically and switch-on bee calling organ begins to report to the police to the staff in time discovers that the earthing circuit breaks down and in time handles.
Drawings
FIG. 1 is a schematic structural view of the alarm device of the present invention;
fig. 2 shows an embodiment of the alarm device of the present invention;
reference numerals: 1-copper bar, 2-buzzer, 3-red indicator light, 4-green indicator light, 5-power supply, 6-equipment needing grounding.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples.
As shown in fig. 1, the NO-normally open contact, relay coil is open when not energized; NC-normally closed contact, the relay coil is conducted when not electrified; COM-common contact, VCC-represents the positive, IN-control terminal of the relay working power supply.

The electromagnetic relay is also connected with a 5v power supply, and the model of the electromagnetic relay is SRD-5 VCD-SL-C.
As shown in fig. 2, when in use, the grounding device 6 is directly connected to the alarm device.
When in work: and (3) normal state: the circuit between the grounding device (equivalent to the copper bar 1) and the equipment 6 needing grounding is electrified, the NO contact is closed, the green light is normally on, and the red light is normally off. This indicates that the anti-static grounding system is in a normal operating state.
And (3) fault state: when a circuit between the grounding device (equivalent to the copper bar 1) and the equipment 6 needing grounding is disconnected, the NO contact is disconnected, the NC contact is connected, the green light is turned off, the red light flickers and the buzzer sounds an alarm; indicating that the grounding copper rod of the anti-static grounding system is pulled out or a fault occurs at a certain position of the line.
Claims (3)
