Embodiment Construction

[0020] Below in conjunction with accompanying drawing and specific embodiment the present invention will be described in further detail: figure 1 In the cover plate mechanism shown, the shape of the cover plate 2 is a symmetrical hexagon, and it is placed on the top of the air chamber 1. The cross section of the air chamber 1 is circular. Connection, as shown in Figure 2, on the other side symmetrical to the movable rotating shaft 3, there are two pairs of fixing holes that cooperate with each other, the air chamber fixing hole 5 and the cover plate fixing hole 6, when the cover plate 2 is tightly closed, use two pairs of fixing holes. Two fixing bolts 4 pass through the fixed hole 5 of the air chamber and the fixing hole 6 of the cover plate to fasten; at the same time, the cover plate 2 is connected with the weight 9 through the load-bearing steel cable 7 and the load-bearing pulley 8, and the two sides of the weight 9 are fixed by The track 10 limits the range of motion in ...

Abstract

In present system of using wave energy, structure of air chamber is an important point. In general protection method, a flush flow unit is setup in structure of air chamber, but this arrangement has obvious disadvantages. Disclosed protection unit as a flush flow orifice is arranged on top of air chamber. Under operating state, the flush flow orifice is closed by a cover board. Compressed air inside the air chamber through aeration conduit impacts turbine to drive power set to generate energy. In case of abnormal circumstance happening, pressure is increased inside air chamber. The protection unit is opened automatically. Pressure is discharged from top of the air chamber so as to protect safety of structure of air chamber, turbine and power set.

Description

technical field [0001] The invention relates to an oscillating water column air chamber protection device in the field of ocean wave energy development. Background technique [0002] Among the current wave energy utilization systems, the oscillating water column wave energy system is the most common, most widely used, and relatively mature technology. The system usually consists of a front port, an air chamber, a ventilation pipe, a turbine, and a generator set. conversion. In the whole system, the structure of the air chamber is a more important link. Its requirement is that it can not only absorb the scattered wave energy well, but also adapt to complex wave conditions. The structural safety of the air chamber is very important. The usual protection method is to arrange a discharge device in the structure of the air chamber. When the wave condition is normal, the discharge device is closed, and the compressed air only does work through the ventilation pipe. When the wave...
