Description

Technical Field

[0001] The utility model relates to the technical field of water level measuring equipment, in particular to a dam safety monitoring water level measuring device with an adjusting structure. Background Art

[0002] A reservoir dam refers to a hydraulic engineering structure that intercepts floods, stores water and regulates water flow. It can be used for irrigation, power generation, flood storage and fish farming. It refers to an artificial lake formed by building a dam at the narrow mouth of a ravine or river. Sometimes natural lakes are also called reservoirs. Water level monitoring requires a water level height value as a warning height. An alarm is issued when the water surface exceeds this water level height. In the existing technology, due to the inconsistent water surface height caused by the dry season and the rainy season, the water level safety value for water level monitoring is also uncertain, and usually requires manual adjustment. It is impossible to adjust the height of the early warning equipment to change the water level safety value.

[0003] For example, the authorized patent document with application number CN202121054579.1 discloses a high-precision automatic water level measurement and monitoring device. Water level observation is a key measurement item in the safe operation of reservoirs, channels, and water transmission lines, and it is also a necessary item. Existing water level measurement devices and equipment mainly include vibrating string water level gauges, ultrasonic water level gauges, float water level gauges, etc. The utility model adopts the principle of laser ranging to monitor the water level in the pressure tube, and applies laser measurement to the water level measurement of the pressure tube; a water level fluctuation elimination device is used to minimize the influence of external factors on the water level change, so as to achieve the purpose of measuring the static water level; an automatic inclinometer is configured to install the equipment on the channel slope, so as to achieve the purpose of directly measuring the channel water level and reduce the large amount of civil engineering work required for existing water level measurement equipment; with a wireless transmission device, online measurement, analysis and sharing of water level monitoring data can be realized.

[0004] The above patent has the problem that the height of the early warning device cannot be adjusted to change the water level safety value. Therefore, we need to provide a water level measuring device for dam safety monitoring with an adjustment structure. Utility Model Content

[0005] The purpose of the utility model is to provide a water level measuring device for dam safety monitoring with an adjustment structure. By setting the measuring cylinder column to be a transparent acrylic material, the height of the buoy block in the measuring cylinder column can be observed intuitively, and it will not be affected by external wind force. The detected value is more intuitive, and the warning values ​​in the dry season and the rainy season are different. By starting the motor to drive the threaded rod to rotate, the surface of the threaded rod is installed with the internal thread of the adjusting cylinder, and the adjusting cylinder and the disc can be height-adjusted. The height of the warning value is automatically adjusted, and the height of the disc can be remotely observed in conjunction with the monitoring probe. When the water surface rises, the top of the buoy block is squeezed against the bottom of the pressure control switch. The bottom of the pressure control switch contains a pressure sensor. After being squeezed, the background data alarm is triggered. The monitoring probe and the pressure control switch are both waterproof, which solves the problems raised in the above-mentioned background technology.

[0006] To achieve the above purpose, the utility model provides the following technical solution: a dam safety monitoring water level measuring device with an adjustment structure, comprising:

[0007] Two fixed plates installed on the slope dam;

[0008] One side of the two fixed plates is fixedly mounted with a measuring cylinder column via a mounting frame;

[0009] A buoy block disposed in the graduated cylinder column;

[0010] An adjusting member mounted on the top of the measuring cylinder column;

[0012] Preferably, the measuring cylinder column is configured as a transparent acrylic column, and a monitoring probe for observing the internal condition of the measuring cylinder column is fixedly mounted on one side of the fixing plate via a mounting seat.

[0013] Preferably, a waterproof lamp is installed on the top of the buoy block, and a protective shell is installed on the top of the waterproof lamp.

[0014] Preferably, a wire tube is fixedly mounted on the top of the buoy block, and the top of the wire tube passes through the top of the measuring cylinder column and extends.

[0015] Preferably, a protective cover with a hole is fixedly mounted on the top of the measuring cylinder column, and the protective cover is arranged on the surface of the motor.

[0016] Preferably, a filter cover is fixedly mounted on the bottom of the measuring cylinder column.

[0017] Preferably, a power storage controller is fixedly mounted on the top of the mounting frame.

[0018] Compared with the prior art, the beneficial effects of the utility model are:

[0019] The utility model sets the measuring cylinder column to be made of transparent acrylic material, so that the height of the buoy block in the measuring cylinder column can be observed intuitively without being affected by external wind force. The detected value is more intuitive, and the warning values ​​in the dry season and the rainy season are different. By starting the motor to drive the threaded rod to rotate, the surface of the threaded rod is installed with the internal thread of the adjusting cylinder, so that the adjusting cylinder and the disc can be height-adjusted. The height of the warning value can be adjusted automatically, and the height of the disc can be observed remotely in conjunction with the monitoring probe.
