Abstract
Description
Technical Field
[0001] This utility model relates to the field of power work manhole cover technology, and in particular to a theft-proof and fall-proof power work manhole cover for motor vehicle lanes. Background Technology
[0002] The power access manhole cover on the motor vehicle lane is an important part of the operation and maintenance of power facilities. It needs to withstand the high-intensity load of vehicles running over it, and also needs to be protected against risks such as theft, falling, and rainwater backflow.
[0003] Existing manhole covers have many drawbacks: poor anti-theft performance, often using simple mechanical locks or no locking structure, making them easy to pry open and steal. This results in roadside traps after the manhole cover is lost, endangering the safety of vehicles and pedestrians, while the internal electrical equipment is also at risk of theft; lack of fall protection, when the manhole cover is damaged or accidentally opened, there is no protective structure to prevent pedestrians and vehicle parts from falling into the manhole, which can easily cause safety accidents; insufficient sealing performance, rainwater from the motor vehicle lane can easily seep into the manhole through the gaps in the manhole cover, causing electrical equipment to become damp and short-circuit, affecting the stability of power supply; these problems seriously affect the safety of motor vehicle lane traffic and the efficiency of power facility operation and maintenance. Therefore, we have proposed an anti-theft and fall-proof motor vehicle lane electrical working manhole cover. Utility Model Content
