Seawater depth finder fixing device for ocean construction

Abstract

The invention discloses an ocean construction seawater depth finder fixing device, and belongs to the technical field of ocean exploration, the ocean construction seawater depth finder fixing device comprises a fixing box, a depth finder main body is arranged in the fixing box, a transducer in a depth finder is located outside the fixing box, and one side of the fixing box is detachably connected with a pressing plate through a lifting structure; the bottom of the pressing plate is slidably connected with a fixing assembly used for vertically placing the transducer, the base is slidably connected with a clamping block, the clamping block is rotatably connected with a clamping transmission mechanism, the clamping transmission mechanism drives the clamping block to clamp the transducer, one side of the base is fixedly provided with a side plate, one side of the pressing plate is fixedly provided with an inserting plate matched with the side plate in an inserting mode, and the inserting plate is fixedly connected with the pressing plate. And the same pressing plate synchronously drives the clamping block and the inserting plate to finish the clamping and fixing action and the inserting and locking action respectively. It is guaranteed that an included angle is not generated between the transducer and the seabed, and the depth measuring accuracy of the depth finder is improved.

Description

technical field [0001] The invention relates to the technical field of marine exploration, and more particularly, to a fixing device for a seawater depth sounder for marine construction. Background technique [0002] Before the construction of marine engineering, it is necessary to detect the seabed conditions, especially the seabed depth detection. The seabed depth detection is completed by the echo sounder installed on the hull. The transducer in the echo sounder emits sound waves vertically to the bottom of the water. When it is reflected back to the transducer when it reaches the bottom of the sea, the depth of the water bottom can be obtained according to the round-trip time of the sound wave and the speed of sound wave propagation in the measured water area. Due to the unpredictable ocean conditions, the transducer needs to have a certain draft depth Usually, the staff will use the rope to fix the transducer and put it into the water to meet its draft requirements.

[0002] Before the construction of marine engineering, it is necessary to detect the state of the seabed, especially the detection of the depth of the seabed. The detection of the depth of the seabed is completed by the depth sounder installed on the hull. When it is reflected back to the transducer at the bottom of the sea, the depth of the bottom can be obtained according to the round-trip time of the sound wave and the propagation speed of the sound wave in the measured water area. Due to the unpredictable ocean conditions, the transducer needs to have a certain draft , usually the staff will use ropes to fix the transducer into the water to meet its draft requirements, but due to the soft structure of the rope, it is easy to make the transducer drift with the waves, which will easily lead to energy conversion The included angle between the transducer and the seabed will affect the measurement results. Moreover, because the transducer is mostly a columnar structure, it is often necessary to use a more complicated shell to fix it when fixing the transducer, so that it can be better integrated with the transducer. The descending structure is connected. This process is not only complicated but also time-consuming and laborious, which will greatly slow down the progress of seawater depth detection. In addition, in other existing patented technologies, CN210625655U uses joint bearings to realize the verticality of sounding equipment, and CN111337228A uses propeller control. The tank and the attitude sensor realize the correction of the underwater attitude of the cylindrical sampler, but the above solution needs to rely on joint bearings, high-precision sensors and complex electronic control equipment, so the reliability is insufficient and the cost is relatively high. In view of this, we propose a Seawater depth sounder fixing device for marine construction
