Problems solved by technology

This measurement method not only needs to measure the depth of the seawater in advance, but is inconvenient to operate; more importantly, due to the influence of the sea current, the rope and the electromagnetic current velocity measuring instrument will be deflected, which not only makes it difficult to ensure the exact position of the electromagnetic current velocity measurement
Method 2: Install the electromagnetic current velocity measuring instrument on the installation stand, and connect the rope below the installation stand to the seabed; although this measurement method is convenient to operate, it is installed on the seabed when the seabed surface is a slope or uneven. The bench will also tend to be deflected, which will lead to the deflection of the electromagnetic flow velocity measuring instrument, which also affects the measurement accuracy of the electromagnetic flow velocity measuring instrument

Abstract

The invention discloses a device for fixing a seabed flow velocity measuring instrument, and aims at providing the device which can effectively prevent the inclination of the flow velocity measuring instrument from affecting the measurement precision, and guarantees the measurement precision. The device comprises an installation rack, a plurality of supporting leg structures which are disposed at the bottom of the installation rack and used for installing the installation rack, a bulb connection structure which is disposed at the top of the installation rack, and an adaptive compressing apparatus.

Description

technical field [0001] The invention relates to an installation device, in particular to a device for fixing a seabed current velocity measuring instrument. Background technique [0002] The bottom seawater velocity usually refers to the flow velocity of the water layer at a certain height from the seabed. It is one of the key factors that must be considered in the site selection of marine engineering construction such as submarine cable and pipeline laying, sea sand mining, mariculture location determination, and artificial fish reef placement. Rationality of site selection for marine engineering construction. [0003] At present, the measurement of bottom seawater flow velocity is usually carried out by electromagnetic current velocity measuring instrument. The current electromagnetic flow rate measuring instrument usually adopts the following two methods: Method 1: hang a counterweight under the electromagnetic flow rate measuring instrument, and lower the electromagnet...
