At present, self-recording water level gauges in the free flow period have been widely used in hydrological stations, realizing complete control of the water level change process.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] The utility model provides Figure 1-3 The river and lake ice age water level monitoring equipment shown comprises a steel pipe base 1, a steel pipe 2 is inserted and connected to the top of the steel pipe base 1, the steel pipe base 1 and the steel pipe 2 together form a hydrostatic cylinder structure, an ultrasonic detection mechanism is arranged on the top of the steel pipe 2, an internal insulation mechanism is arranged at the contact position between the steel pipe base 1 and the steel pipe 2 and the ice surface, the internal insulation mechanism comprises an insulation casing 3, and an internal insulation component is arranged in the inner interlayer of the insulation casing 3.

After the matching design of the two steel pipes, the reading range of the instrument can be increased to 988.50m to 989.70m.

[0025] Furthermore, the temperature control unit includes a temperature controller 8 , and an electrical control end of the temperature controller 8 is electrically connected to the energized end of the heating wire 302 .

[0026] It should be noted that, through the setting of the temperature controller 8, the temperature inside the thermal insulation sleeve 3 is first monitored, and by controlling the power supply and heating of the heating wire 302, the gap between the inner wall of the thermal insulation sleeve 3 and the hydrostatic tube structure is always maintained within a specific temperature range to ensure that the gap between the thermal insulation sleeve 3 and the hydrostatic tube is not frozen.

[0027] In the second embodiment, the outer diameter of the heat preservation tube 3 is set to 35cm, the inner diameter is 15cm, the length is 1.3m, it is open and bottomless, and the length can be adjusted according to the ice thickness over the years; the top of the heat preservation tube 3 is not closed in the early stage, and a circle of 5cm thick heat preservation cotton is used to fill the inner and outer walls of the interlayer, close to the outer wall of the interlayer, and the gap between the heat preservation cotton and the inner wall of the interlayer is 5cm.

[0042] The communication module 6 uses a mobile 4G network channel to transmit the water level data collected by the front end to the server in the computer room. The communication module 6 is a radio type and can achieve data transmission within 1km;

[0043] As a preferred implementation, the communication module 6 adopts a 4G-DTU module type, which is used to achieve long-distance data transmission and break through distance limitations.

[0055] Instrument altitude: the distance between the ultrasonic sensor 7 and the water surface;

[0056] Water level amplitude: the first data processing (for example, 0.1 in the figure above means that the latest set of data is compared with the previous set of data. If the absolute value of the interpolation between the two is greater than 0.1m, it is discarded and the previous set of data is used to replace the latest data);

[0057] Real-time water level: the latest set of data;
