Problems solved by technology

Although the wave height meter ZH7331 can measure wave heights at different water depths, it needs to customize capacitance probes of different lengths according to the measurement range
In addition, there are some lifting and folding wave height meters, which can measure different water depths, but their measurement lengths are limited

Embodiment 1

[0020] Such as figure 1 As shown, the field wave height meter includes: a base 1, a steel pipe, a capacitor line 5, a data processor 6, and a wire winder 7. The steel pipe includes a first steel pipe 2, several connecting steel pipes 4 and a second steel pipe 3. The base 1 One end of the first steel pipe 2 and the capacitance line 5 are welded and fixed respectively, the other end of the first steel pipe 2 is connected to the steel pipe 4, the other end of the steel pipe 4 is connected to the second steel pipe 3, and the other end of the second steel pipe 3 is fixed on the data At the bottom of the processor 6, the other end of the capacitor wire 5 is wound on the wire winder 7, and the wire winder 7 is fixed on the bottom of the data processor 6, and the capacitor wire 5 and the steel pipe are both perpendicular to the base.

[0021] Such as figure 2 As shown, the first steel pipe 2 includes a thick portion of a first steel pipe and a thin portion of a first steel pipe, and...

Embodiment 2

[0023] Example 2 On the basis of Example 1, the diameter of the thick part of the first steel pipe 2, the connecting steel pipe 4 and the second steel pipe 3 is set to 1.8 cm, and the diameter of the thin part is set to 1 cm.

Embodiment 3

[0025] In Embodiment 3, an antenna 8 is added on the basis of Embodiment 1 or 2, and the antenna 8 is arranged on the top of the data processor 6 to realize data exchange between the altimeter and the mobile terminal. The mobile terminal can be a mobile phone, a notebook or a tablet computer.

[0026] Working principle: before using the altimeter of this embodiment to measure, first determine the number of connecting steel pipes 4 according to the water depth, and install the connecting steel pipes 4 between the first and second steel pipes, and the steel pipes are fixed by threading. Then the wave height meter is vertically sent into the water. When the water wave height changes, due to the different capacitance of the electric wire in the water and in the air, the data processor 6 uses capacitance-specific detection to convert the specific voltage value obtained by the integrated chip, and then according to the detection voltage and the wave height. The linear relationship y...

The height-changeable field wave-height meter includes a base, a steel pipe, a capacitance line, a data processor, and a line winding device; the steel pipe includes a first steel pipe, a plurality of connection steel pipes, and a second steel pipe which are successively connected; the steel pipe and the capacitance line are arranged between the base and the data processor; the steel pipe is fixedly connected to an upper part of the base through one end of the first steel pipe, and is fixedly connected to the bottom of the data processor through one end of the second steel pipe; one end of the capacitance line is fixedly connected to the upper part of the base, and the other end of the capacitance line winds around the line winding device; the line winding device is fixed on the bottom of the data processor; and the steel pipe and the capacitance line are perpendicular to the base. The wave-height meter is splitting,is portable, can meet the demands of different environments for the length of the wave-height meter, and is flexible and adjustable in height.

Description

technical field [0001] The invention belongs to the field of instruments and equipment, in particular to a field wave height meter with variable length. Background technique [0002] Wave height is the vertical distance between adjacent wave crests and troughs, which can reflect the average energy state of the water surface in the field. It is one of the important parameters in the field experiment research, and it is related to the speed and safety of the ship. [0003] The depth of the water source in the field is not constant. If the maximum length of the wave height meter is less than the water depth, the wave height cannot be measured, and an instrument of other length needs to be replaced. However, if the length of the wave height meter is made longer to adapt to different water depths, the volume of the instrument will be too large , inconvenient to transport. For example, the wave height meter YWS200-X can only measure the wave height at a water depth between 0 and ...
