Description

technical field [0001] The invention belongs to the technical field of wave energy generating devices, and in particular relates to a tidal range liquid level signal measuring device and a combined oscillating float type wave energy generating device. Background technique [0002] Wave energy is a clean energy with rich content. In order to utilize wave energy, combined oscillating buoy type wave energy generating devices are widely used to utilize wave energy. The combined oscillating buoy type wave energy generating device is fixed together with the counterweight on the seabed through cables, and generally includes an oil cylinder, an oil cylinder support arm, a float, and a screw jack. The power generation device is working normally, and its oil cylinder must change its height and position at any time due to the influence of seawater tidal range. Since the tide level in the ocean changes at any time, in order to make the float and oil cylinder work normally, the oil cylin...

Problems solved by technology

[0005] When the tide level becomes high, the trigger mechanism touches the travel switch, and the signal is transmitted to the actuator. When the tide level goes from high to low, the travel switch also performs actions in sequence to provide a downward signal. The signal provided by the travel switch is mechanical contact, but because the wave has a clear size uncertainty, the mechanical contact is easy to cause mechanical damage to the travel switch, and the travel switch will fail quickly

[0006] Due to the mechanical contact of the limit switch type liquid level measurement, it is easy to cause damage and failure, and it requires high logic judgment of the electrical system, and because it is a mechanical contact, it requires accurate contact with the mechanism of the system, and the signal acquisition is too affected by waves. , the accuracy is low, the deviation is about ±15cm

In addition, the signal provided by the limit switch measurement is difficult for the system to judge, it is not easy to judge whether the tide level is rising or falling, and it is easy to cause misoperation, the limit switch type measuring device has poor applicability to waves, and the signal is easy to fail

[0007] In addition, the limit switch type liquid level measurement signal processing has many disadvantages. One is that the signal generated by the wave size cannot be processed. If a large wave comes, the height of the float is too high, which makes the trigger of the touch lever The point exceeds the limit switch, which is likely to cause mechanical damage to the limit switch. Second, because this method is frequent mechanical contact, it is easy to cause damage to the components. Third, it is difficult for the system to process the signal itself, especially when the tide level rises to the highest level. Starting to fall or turning point from the lowest to rising, the signal processing is prone to problems
