Description

Technical Field

[0001] The utility model relates to the technical field of water level detectors, and more specifically to a foundation pit water level detector. Background Art

[0002] A deep foundation pit refers to an excavation with a depth of more than three basement floors, or a project with a depth of less than 5 meters but with particularly complex geological conditions, surrounding environment and underground pipelines. There are more and more deep foundation pit projects in construction projects, especially in areas with high groundwater levels. It is necessary to conduct water level testing on the groundwater inside the foundation pit. After the test, based on data analysis, it is determined whether the water level in the foundation pit exceeds the ideal water level and whether there will be any damage to the foundation pit, in order to facilitate construction.

[0003] The existing announcement number is CN207959223U, and the name is a water level monitoring device for foundation pit construction. After the water level detection device is moved to a suitable position by a walking mechanism, the water level monitoring device is fixed, and then the first gear is driven to rotate by the output shaft of the second driving device, thereby driving the second gear to move, and then driving the rotating rod to rotate. While the rotating rod rotates, it drives the carrying box to rotate on the rotating rod, so that the carrying box rotates. Since the upper end of the carrying box is fixed with a first driving device, the first bevel gear is driven to move under the drive of the first driving device. Since the first bevel gear and the second bevel gear are engaged with each other, and because the second bevel gear is fixed on the screw rod, the screw rod is driven to rotate. Since one end of the screw rod is threadedly sleeved in the casing, the casing is driven to move on the screw rod, and then the position of the casing is adjusted. Since a connecting plate is fixed at one end of the casing, a winder is fixed at the lower end of the connecting plate, a pull rope is wound on the winder, and a water level detector is fixed at the lower end of the pull rope to detect the water level in the foundation pit.

[0004] However, the above-mentioned real-time water level detector for observation wells in deep foundation pits has a low degree of automation in detection. It cannot automatically alarm when the water level is too high and cannot remind the workers in time. Since the workers may omit due to various problems, they cannot operate in time when the groundwater level is too high, which affects the safety of later construction. Utility Model Content
