Description

Technical Field

[0001] The utility model relates to the technical field of alarm equipment, and more specifically to an automatic alarm device for preventing high voltage electricity. Background Art

[0002] High voltage refers to the household wiring with an AC voltage of more than 1000V or a DC voltage of more than 1500V in the distribution line. According to the definition 2.1 in GB / T 2900.50-2008, high voltage usually refers to a voltage level higher than 1000V (not included). In specific cases, it refers to the voltage level of power transmission in the power system. Compared with ordinary power sources, high voltage has its own special hazards. There are two special situations of high voltage electric shock: one is high voltage arc electric shock, and the other is step voltage electric shock. Since the voltage is very high, it is easy to cause electric shock to death. Therefore, the staff often inspects the high voltage poles to prevent the failure of the insulation coating and the occurrence of high voltage leakage. However, the existing detection methods are mostly carried out by the staff through the current testing equipment, which not only brings great risks to the personal safety of the detection personnel, but also makes the test difficult to operate. Moreover, the leakage does not necessarily occur at the moment close to the detection time point. If the leakage occurs during the detection interval, it will bring great danger of electric shock to the surrounding residents and creatures. In view of this, we propose an automatic alarm device for preventing high voltage electricity. Utility Model Content

[0022] Specifically, the insertion rod 1 is in the shape of a Chinese character "Z"; the lower end of the insertion rod 1 is inverted frustum structure; the outer wall of the extrusion rod 3 is gap-matched with the inner wall of the cavity 2; the inner end of the pressure plate 4 is in the shape of a Chinese character "Z"; the inner walls on both sides of the plate groove 5 are both concave arc structures; the outer end of the pressure plate 4 extends through the plate groove 5 to the outside and slides with the plate groove 5.

[0023] Furthermore, the inner end of the plug block 7 is a right-angled triangular pyramid structure with an inclined surface facing upward, and the outer end of the plug block 7 is a quadrangular pyramid structure. The plug block 7 is slidably matched with the block groove 6, the bottom surface of the extrusion rod 3 is extruded and matched with the inner end of the top surface of the plug block 7, and the outer end of the compression spring 9 is connected and fixed to the inner wall of the cavity 2. When the staff uses the device to warn of leakage of high-voltage electricity, they can first use the lower end of the plug rod 1 to insert the device into the land around the high-voltage power pole. Under the structure of the Chinese character, the plug rod 1 of the device will not be completely immersed in the soil layer, and then The staff can press the pressing plate 4 to descend along the plate groove 5. During the process, the Chinese-character-shaped pressing plate 4 and the plate groove 5 that slides with it will limit the extrusion rod 3. In this way, the extrusion rod 3 will steadily descend and produce an extrusion effect on the top surface of multiple plug blocks 7 at the lower part of the cavity 2. Under the setting of its inclined surface, multiple plug blocks 7 will be pushed out of the device along the block groove 6.

Under the setting of the Chinese-shaped structure, the plug rod 1 of this device will not be completely immersed in the soil layer, and then the staff can press the pressure plate 4 to descend along the plate groove 5. During the process, the Chinese-shaped pressure plate 4 and the plate groove 5 that slides with it will limit the extrusion rod 3, so that the extrusion rod 3 will steadily descend and produce an extrusion effect on the top surface of the multiple plug blocks 7 at the bottom of the cavity 2. Under the setting of its inclined surface, the multiple plug blocks 7 will be pushed out of the device along the block groove 6, and then under the setting of the four-sided pyramid structure at the outer end of the plug block 7, the multiple plug blocks 7 can be inserted into the soil in the shape of tree roots to form an anchoring effect. , so as to fix the device.

Then the conductive plates 17 and the metal sheets 18 on the inner walls of the clamping plates 13 and the side plates 12 will come into contact with the outer wall of the high-voltage pole. If the insulating coating of the high-voltage pole fails and becomes charged, a path will be immediately formed between the conductive plates 17 and the metal sheets 18 on both sides and the wires 11 and the warning lights 10.
