A rapid cutting window opening device and window opening method for a reservoir gate

Abstract

The invention discloses a quick-cutting and window-opening device for a reservoir gate and a window-opening method thereof. The quick-cutting and window-opening device for a reservoir gate includes a cutter, an explosion device and a magnetic fixing device, and both the initiation device and the magnetic fixing device are installed on the cutter . The rapid cutting and window opening device for the reservoir gate is adsorbed on the gate steel plate by the magnetic fixing device. After the cutter is detonated by the detonating device, the energy-gathering metal jet will be generated to cut through the gate steel plate, so as to realize the rapid opening of the reservoir gate, so as to remove the outside of the gate. The water is diverted by the diversion hole, so that the water pressure inside and outside the gate is balanced, and the stuck gate can be lifted smoothly. This cutting and opening device can effectively solve the problem that the old reservoir gate cannot be lifted normally, and greatly reduces the construction difficulty and construction period. At the same time, it can avoid the safety hazards of personnel and mechanical equipment operation, and realize the purpose of quickly cutting and opening the reservoir gate.

Description

technical field [0001] The invention belongs to the technical field of reservoir gate accident treatment, and in particular relates to a rapid cutting window opening device and a window opening method for a reservoir gate. Background technique [0002] Along with the construction of a large number of reservoirs at home and abroad, some old reservoirs are being renovated and repaired more and more. Usually, before the renovation and maintenance, the reservoir gates need to be lifted to let off the water in the reservoir. And often sometimes because of the old reason of the reservoir, some gates cannot be lifted normally. At this time, it is necessary to cut and open the gate at one end of the reserved diversion hole, so that the water in the reservoir can be exported through the diversion hole. The existing conventional manpower and mechanical cutting methods cannot be carried out, because once the gate is cut and opened, the water in the reservoir will quickly flow into the ...
