AI Technical Summary
At the construction site, the water level of the precipitation well pipe is difficult to monitor in real time, resulting in the pump stopping or the water level is too low, affecting the construction progress and project quality. Existing float water level gauges may affect the accuracy of monitoring data when impurities or sediments are present in water.
A monitoring device including a rope coiler, a wire rope, a high water level sensor and a low water level sensor are designed. The wire rope is tightened by a rope coiler, and the high and low water level sensor is fixed to the wire rope to monitor the water level of the well pipe, and the wire rope is tightened by the counterweight.
The monitoring and early warning of the water level of the precipitation well pipe is achieved, and construction problems caused by excessive or low water level are avoided. The fixed design of the sensor avoids the impact of water buoyancy, ensuring the accuracy of the monitoring data.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of building construction, and particularly relates to a device for monitoring the water level of a well pipe of a precipitation well. Background Art
[0002] At present, during the dewatering process in the foundation pit of the construction site, the dewatering pump often stops running, and the water level in the dewatering well is too low, resulting in idling and burning of the pump. If you are not careful, it will seriously affect the on-site construction, and even the quality and construction period of the construction project will be affected due to the untimely dewatering. In reality, due to the large number of dewatering well pipes, it is difficult to arrange special personnel to check the dewatering situation at any time, so a water level monitoring device is used to monitor the water level. At present, the most commonly used is a float-type water level gauge, which can monitor the water level in real time. In this way, if there are a lot of impurities or sediments in the water, it may affect the float and cause the accuracy of the monitoring data. Utility Model Content
[0003] The utility model aims to provide a device for monitoring the water level of a well pipe in a precipitation well.
[0004] The utility model is realized through the following measures: a device for monitoring the water level of a well pipe in a precipitation well, characterized in that it includes a rope reel arranged on the ground, a steel wire rope wound on the rope reel, a high water level sensor and a low water level sensor arranged on the steel wire rope through a connecting piece, and a counterweight fixedly arranged at the end of the steel wire rope.
[0005] The high water level sensor and the low water level sensor monitor the water level of the precipitation well pipe. When the high water level sensor detects a signal, a high water level warning is issued; when the low water level sensor detects a signal, a low water level warning is issued. The transmission signals of the high water level sensor and the low water level sensor are received and the warning is issued using existing technology, which will not be described in detail here.
[0006] The counterweight may be a small anchor.
[0007] The connecting piece is an annular buckle with an opening, and the opening is connected by a plurality of bolts;
[0008] A mounting plate is arranged on the outer wall of the annular buckle via a plurality of support rods, and mounting holes are arranged on the mounting plate. The upper ends of the high water level sensor and the low water level sensor pass through the mounting holes and are fixed by nuts.
[0009] The outer wall of the annular buckle is evenly distributed with a plurality of reinforcement protrusions in the circumferential direction.
[0010] A plurality of extrusion protrusions are evenly distributed on the inner wall of the annular buckle in the circumferential direction.
[0011] The rope reel comprises a bracket, a drum rotatably arranged on the bracket, and a protective cover arranged on the periphery of the drum. The lower end of the protective cover is provided with an outlet for the wire rope.
[0012] The bottom plate of the bracket is fixed on the ground and a guide wheel is arranged at one end of the bottom plate close to the precipitation well, and the steel wire rope passes over the top of the guide wheel.
[0013] An upper adjusting column and a lower adjusting column made of elastic material are fixedly arranged on the steel wire rope, and the high water level sensor and the low water level sensor are fixed on the corresponding adjusting columns through the connecting piece.
[0014] Working principle: collect the depth of the precipitation well in advance, adjust the distance between the high water level sensor and the low water level sensor to meet the water level monitoring requirements, and after the adjustment is completed, rotate the rope reel until the counterweight is in the bottom soil of the precipitation well and rely on gravity to keep the wire rope in a taut state. After fixing the position of the wire rope, water level monitoring can be carried out at this time.
[0015] The beneficial effect brought about by the technical solution provided by the embodiment of the utility model is: for the water level of the precipitation well pipe, it is only necessary to ensure that the water level is not too high or too low to meet the use requirements. The present application adopts two relatively fixed high water level and low water level sensors, which can realize the monitoring and early warning of high water level and low water level; when in use, the high water level and low water level sensors are fixed in position on the precipitation well and are not affected by water buoyancy.
