The fixing piece comprises a small ring on the upper portion and a large ring on the lower portion, the upper ring and the lower ring are connected into a whole to form a gourd body, the gourd body is formed by combining two half gourd bodies and is fixed through bolts and nuts of the upper portion, the middle portion and the lower portion, the small ring on the upper portion is sleeved on the exhaust pipe, the large ring on the lower portion is sleeved on the water supply pipe, and the exhaust pipe is fixed on the water supply pipe.
The fixing pieces are arranged at intervals so as to be fixed according to needs.
The air pump is conventional equipment, so that the air pump can be started to work according to needs, and air in the water supply pipe is pumped out.
The utility model has the following advantages and effects: by adopting the scheme, the air in the water supply pipe is timely and quickly pumped out through the air pump and the exhaust pipe, so that the water flow in the water supply pipe reaches the process requirements as soon as possible, the water-turbine generator set can be normally started, the air pump is kept to be closed when the water-turbine generator set normally operates, the air-turbine generator set has the advantages of quick and thorough air discharge, convenience in operation and the like, and reliable technical support is provided for guaranteeing the normal starting of the water-turbine generator set.
