Description

Technical Field

[0001] The utility model relates to the technical field of multi-beam depth sounders, in particular to a multi-beam depth sounder used for seabed detection. Background Art

[0002] A multi-beam echo sounder is a device that uses sound waves to detect seabed topography. It is mainly used for seabed topography measurement, sea sweeping measurement, and offshore construction area measurement. A multi-beam echo sounder usually contains multiple adjacent narrow-beam echo sounders. The echo feedback of multiple sound waves can form a real-time seabed topography map, which is convenient for subsequent construction work. After searching, the prior art (application number: CN202120284578.X) records "a multi-beam echo sounder for seabed detection, including an underwater unit, a fixing part is installed on the upper end face of the underwater unit, a protective cover is arranged on the outside of the underwater unit, a first electrically-controlled telescopic rod is installed on the inner top of the protective cover, the lower end face of the first electrically-controlled telescopic rod is detachably connected to the upper end face of the fixing part, a plurality of springs are fixedly connected to the outer wall of the protective cover, and an anti-collision cylinder is fixedly connected to the other end of the plurality of springs. When a marine organism collides, the plurality of springs drive the anti-collision cylinder to quickly return to its original position according to their own resilience, so as to avoid left and right shaking and damage to the underwater unit, thereby achieving the effect of preventing collision and damage to the underwater unit during the detection process, and avoiding the problems of inaccurate detection data caused by the collision of marine organisms with the detection device, damage to the detection device, and easy loss of the underwater unit."

[0003] However, although the multi-beam echo sounder used for seabed detection in the prior art has achieved the underwater anti-collision effect, it still has some shortcomings: the existing multi-beam echo sounder used for seabed detection achieves the effect of driving away underwater creatures by setting up sharp-angled protrusions, but when the underwater creatures collide with the sharp-angled protrusions, since the anti-collision tube is in a water suspended state, the collision will also cause the overall shaking of the device, thereby affecting the measurement accuracy. Secondly, the sharp-angled soil blocks will cause harm to the underwater creatures and affect the ecological balance. In addition, the single connecting rod is fixed at a single point, and when the outer end is connected to the protective cover and the storage tube, it is subject to a larger gravity at one end, resulting in a deviation in its support stability. Utility Model Content

[0004] In order to overcome the defects of the prior art, a multi-beam echo sounder for seabed detection is provided to solve the problem that the existing multi-beam echo sounder for seabed detection is not convenient for driving away underwater organisms and the overall stability deviation of the device.

[0005] To achieve the above-mentioned purpose, a multi-beam echo sounder for seabed detection is provided, comprising: a base, a support frame, an echo sounder device and a driving device, wherein a platform is fixed on the upper side of the base, and an adjusting shaft is connected to the upper end of the platform, and the support frame is fixed to the upper end of the adjusting shaft, and a bridge plate is hinged on the top of the support frame, one end of the bridge plate is connected to a drum through a steel wire rope, and a winch is installed on the upper side of the other end of the bridge plate, and the echo sounder device is connected to the lower side of the winch, and the driving device comprises a low-frequency speaker installed on the outer wall of the echo sounder device, and a hydrophone is provided on the upper end of the low-frequency speaker.

[0006] Furthermore, a first motor is installed on one side of the platform, and a planar gear set is connected to the upper end of the first motor, and the planar gear set is connected to the outer side of the adjusting shaft.

[0007] Furthermore, a stabilizing frame and an axis plate are horizontally connected to the outer side of the support frame, and a second motor is installed on the upper end of the stabilizing frame. At the same time, the output shaft end of the second motor is connected to a driving shaft, and the lower end of the driving shaft is rotatably connected to the upper side of the axis plate.

[0008] Furthermore, the outer side of the driving shaft is connected to a bevel gear set, the outer side of the bevel gear set is connected to a rotating shaft, and the reel is rotatably connected to the outer side of the rotating shaft.

[0009] Furthermore, a group of parallel hanging blocks are connected to the lower side of the stabilizing frame, and the rotating shaft rotates through the hanging blocks while maintaining a horizontal state.

[0010] Furthermore, the upper end of the hydrophone is connected to an elastic cable, and the upper end of the elastic cable is connected to a sound controller, and the sound controller is installed at the lower end of the stabilizing frame.

[0011] Furthermore, the depth sounder device includes an outer protective cover, and an electrically controlled telescopic rod is provided on the inner side of the protective cover, and the lower end of the electrically controlled telescopic rod is connected to the underwater unit through a fixed block, and a weight block is provided on the outer side of the protective cover.

[0012] The beneficial effects of the utility model are:

[0013] 1. The driving device includes a sounding controller, an elastic cable, a hydrophone and a low-frequency speaker. When the depth sounder enters the seawater, the sounding controller generates low-frequency ultrasonic waves, which are then diffused through the hydrophone and the low-frequency speaker to drive away the surrounding underwater creatures and avoid collision damage to the underwater creatures.

[0014] 2. The first motor, the flat gear set and the adjusting shaft are used to adjust the angle of the support frame, so that the position of the depth sounder equipment can be moved and changed through the bridge deck. At the same time, the second motor, the stabilizing frame, the rotating shaft and the reel are used to apply force to one end of the bridge deck, so that the fulcrum of the support frame can form a relatively stable moving state for the other end of the bridge deck, and then cooperate with the winch to make the depth of the depth sounder equipment dive into the sea water to a greater depth.

[0022] Specifically, the connection mode between the bridge plate 14 and the support frame 13 is similar to a seesaw structure, so that a relatively stable supporting effect is achieved when the adjusting shaft 12 is rotated for adjustment.
