Semi-submersible unpowered channel silt flushing ship and channel desilting method
The invention discloses a semi-submersible unpowered channel silt flushing ship and a channel desilting method. A water passing channel is formed in the bottom of the middle of a cavity ship box, thecaliber of the water passing channel is gradually decreased from a water passing channel inlet to a water passing channel outlet, and a nozzle is movably connected to the exterior of the water passingchannel outlet; and water filling valves are arranged at the bottoms of two sides of the cavity ship box, a water pumping device is arranged at the top of the cavity ship box, the water inlet end ofa water suction pipe of the water pumping device is arranged at the bottom of a cavity body of the cavity ship box, and the water outlet end of a water drainage pipe of the water pumping device extends to the outer side of the cavity ship box. When the channel is desilted, the cavity ship box is dragged to the silt accumulation position. Water is injected into the cavity ship box through the waterfilling valves, the water passing channel sinks into the water, a ship body is fixed, and desilting is carried out on water flow accelerated through the channel through the nozzle. Due to the fact that the caliber of the water passing channel is gradually reduced from the inlet to the outlet, accelerated water flow penetrating through the contractible channel of the ship body is used for performing disturbance silt flushing, and then flexible desilting operation of the channel can be achieved by moving the cavity ship box.
本申请公开了一种半潜式无动力渠道冲淤船及渠道清淤方法，空腔船箱中间底部为过水通道，过水通道从过水通道进口到过水通道出口口径逐渐变小，过水通道出口外活动连接一喷嘴；空腔船箱两侧底部位置设置有充水阀门，空腔船箱顶部设置有抽水装置，抽水装置吸水管的进水端设置在所述空腔船箱的腔体底部，抽水装置排水管的出水端延伸至所述空腔船箱外侧。对渠道进行清淤时，将空腔船箱牵引至积淤处。通过充水阀门向空腔船箱注水，过水通道沉入水中，船体固定，通过通道加速后的水流利用喷嘴进行清淤。由于过水通道从进口到出口口径逐渐缩小，利用贯通船体收缩性通道的加速水流进行扰动冲淤，进而可以通过移动空腔船箱的位置实现渠道的灵活清淤作业。
