Directly-buried cable theft prevention device

Abstract

The invention discloses a directly-buried cable theft prevention device, which comprises a base (9). The upper end of the base (9) is provided with an end cover (3); a tightening screw rod (4) is arranged below the end cover (3); the end cover (3) is opened, a special tool is used to rotate the tightening screw rod (4), a cable stop sliding block (5) actively connected with the tightening screw rod (4) moves downwardly, a clamping and blocking layer (8) at the bottom of the base (9) tightly clamps the cable, the cable is bent to form an inverted S type, the clamping and blocking layer (8) canprovide large resistance when the cable with a smooth surface is extracted, and the cable is not easily dragged and pulled out; and when the cable needs maintenance and replacement, the special tool reversely rotates the tightening screw rod (4), the cable stop sliding block (5) moves upwardly, and the cable gets loose. The directly-buried cable theft prevention device is hidden underground or inside a wall body of a building, a theft needs to perform ground ditching or wall drilling along the cable direction, huge manual time and cost are consumed for cable stealing, and the loss outweighs the gain.

Description

technical field [0001] The invention relates to a direct-buried cable anti-theft device, which is suitable for cable anti-theft. Background technique [0002] In recent years, cable theft has brought great impact and harm to society and families. Although the country has promulgated laws to punish it resolutely, there are always criminals who take risks. More than 90% of power outages are caused by thieves stealing cables. This kind of theft not only endangers society but also seriously threatens the safety of thieves themselves. The existing buried cable installation has no anti-theft measures. Thieves can easily steal hundreds of meters or even thousands of meters of cables by cutting off one end of the buried cable and pulling out the other end of the cable; although some cable installations adopt electronic anti-theft Alarm device, but this technology needs to be equipped with full-time guards, which virtually increases labor costs. After the theft accident, the power ...

Problems solved by technology

The existing buried cable installation has no anti-theft measures. Thieves can easily steal hundreds of meters or even thousands of meters of cables by cutting off one end of the buried cable and pulling out the other end of the cable; although some cable installations adopt electronic anti-theft Alarm device, but this technology needs to be equipped with full-time guards, which virtually increases labor costs

After the theft accident occurs, the power users or households have to spend a lot of manpower and material resources to re-climb the overhead line or dig trenches to restore the power supply, and take corresponding measures to prevent the theft from happening again, which seriously affects the power consumption.
