Abstract
The present invention relates to a ground subsidence detection apparatus, which is capable of continuous detection of ground subsidence, predicts the occurrence of sinkholes and thus can preemptively prevent a sinkhole from forming, and due to having a simple structure, can increase durability and reduce cost. Provided is a ground subsidence detection apparatus exhibiting an alarm color using reflection of a light source and a detection weight, which, without using a separate power source, falls due to gravity in the event of cavity formation in the ground, or falls due to ground movement when ground movement occurs.
Claims10
A ground subsidence detection apparatus comprising:
- a pipe-shaped main body;
- a transparent cover that is coupled to one end of the main body;
- a detection weight that is disposed at an opposite end of the main body and moves when a cavity in a ground occurs or when movement of the ground occurs;
- a display unit that is installed within the main body to be connected to the detection weight and has one or more reflective surfaces with a warning color;
- and
- a connection unit that connects the detection weight and the display unit,
- wherein the display unit comprises a rotating shaft rotatably installed in the main body;
- and a reflector installed on or wound around the rotating shaft and having at least two reflective surfaces, each of the at least two reflective surfaces having a different warning color,
- wherein as the detection weight moves, the rotating shaft and the reflector rotate together, wherein the at least two reflective surfaces are arranged to face the transparent cover in sequence, so that a corresponding warning color is reflected through the transparent cover.
