Underwater deposition thickness detection device

Abstract

The invention provides an underwater deposition thickness detection device, and relates to the technical field of underwater detection equipment. The underwater deposition thickness detection device comprises a protection frame, an observation box, a measuring rod, an observation camera and a rope, the protection frame is used for being supported on deposition, and a lifting lug is arranged at the top of the protection frame; the observation box is arranged in the protection frame and comprises a closed containing cavity and a channel penetrating in the height direction, and the side wall of the channel is provided with a transparent area. The measuring rod is movably arranged in the channel, a hanging ring is arranged at the upper end of the measuring rod, scales are arranged on the measuring rod, and the measuring rod is used for being inserted into sediment; the observation camera is mounted in the accommodating cavity and is used for observing the scales of the measuring rod through the transparent area to obtain the length of the measuring rod inserted into the deposit. One end of the rope is used for being connected to the shore, and the other end of the rope penetrates through the lifting ring on the measuring rod and is connected to the lifting lug of the protection frame. The device can rapidly, conveniently and economically measure the silt deposition thickness of the hydropower station stilling pool bottom plate in turbid water.

Description

technical field [0001] The invention relates to the technical field of underwater detection equipment, in particular to an underwater deposition thickness detection device. Background technique [0002] The water cushion ponds, stilling basins, and tailraces in the flood discharge and energy dissipation structures of hydropower stations have regular shapes. Taking the stilling pool as an example, the structure is similar to a large swimming pool. The bottom plate is made of special reinforced concrete blocks through splicing. The general water depth in the stilling pool ranges from a few meters to tens of meters. Due to the particularity of the structure, and the high sand content in the river water, the water quality is turbid, so there are silt bodies of variable thickness in the stilling pool, and it is impossible to use conventional means to let the hydropower station staff know in time. The sediment at the bottom of the surface hole stilling tank is generally about 1 c...
