Description

Technical Field

[0001] This utility model relates to the field of perimeter testing, and in particular to a portable perimeter testing tool. Background Technology

[0002] At oil and gas extraction and transportation stations, the stations are required to be managed in a zoned and data-driven manner. Each station is equipped with a perimeter alarm system. To ensure the accuracy of each perimeter alarm system, it is necessary to test the perimeter alarm systems of each zone regularly.

[0003] However, since the sensing range of perimeter alarm systems is usually set on the top of the wall, using brooms or cardboard to block the signal source of the perimeter alarm to simulate the situation of people breaking in is cumbersome and easy to cause injury when testing perimeter alarms. Brooms do not completely block the signal source and require repeated operation. Cardboard requires people to climb the wall. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies, such as cumbersome perimeter alarm testing operations that are prone to causing injury, and to provide a portable perimeter testing tool.

[0005] This utility model provides a portable perimeter testing tool, including

[0006] A baffle plate, wherein the baffle plate is provided with a first limiting groove and a second limiting groove;

[0007] The movable head is detachably connected to the baffle plate and is used to adjust the relative position of the baffle plate and the telescopic rod.

[0008] A telescopic rod having at least two telescopic joints, the telescopic rod being detachably connected to the baffle plate;

[0009] The first limiting groove can hold and limit the movable head, and the second limiting groove can hold and limit the telescopic rod.

[0010] This utility model discloses a portable perimeter testing tool. A shield and a movable head are detachably connected, as are the movable head and the telescopic rod. When not in use, the movable head and the telescopic rod can be respectively locked in a first limiting groove and a second limiting groove, allowing the shield, movable head, and telescopic rod to be stored as a set for easy carrying and improved portability. In use, the shield blocks the signal source, simulating an intrusion scenario, thus providing better shielding. The movable head can adjust the relative position of the shield and the telescopic rod, making it easier for the shield to completely block the signal source. The telescopic rod's length can be adjusted through the relative displacement between its telescopic joints, allowing operators to block signal sources at different heights from the ground.

[0011] Preferably, the shielding plate has a connecting hole, and the end of the movable head has a connecting part, and the connecting hole is threadedly connected to the connecting part.

[0019] Preferably, the first folding plate and the second folding plate are respectively disposed on opposite sides of the shielding plate.

[0020] This ensures the weight of the shield is balanced, and after the shield is raised, its position can be easily adjusted by rotating the telescopic rod to guarantee the shield's effectiveness in blocking the signal source.

[0021] Preferably, the shielding plate is provided with a plurality of first magnetic attractors and a plurality of second magnetic attractors, wherein the first magnetic attractors are magnetically connected to the first folding plate, and the second magnetic attractors are magnetically connected to the second folding plate.

[0022] The first and second magnetic attractants respectively attract the first and second folded plates, keeping them in an unfolded state.
