Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary support structures, and particularly relates to a support for avoiding the interference of a hoisting frame on underwater three-dimensional sonar operations. Background Technique

[0002] The accumulation of sediments at the bottom of a reservoir may pose a safety hazard to the dam. Therefore, the timely monitoring and cleaning of the sediments at the bottom of the dam are crucial. Traditional sediment detection methods are often limited by the visual range and water quality conditions, and it is difficult to comprehensively and efficiently obtain the sediment information at the bottom of the reservoir. Three-dimensional sonar is a technology for detecting underwater objects by sound waves. It utilizes the characteristics of sound waves propagating in water, and obtains information such as the position, shape, and size of underwater targets by sending sound wave signals and receiving their echoes. Compared with traditional optical or mechanical methods, three-dimensional sonar technology has the advantages of all-weather, high resolution, and high efficiency, and is suitable for real-time monitoring and imaging in complex underwater environments. In the detection of sediments at the bottom of a dam, three-dimensional sonar technology can play an important role.

[0003] By mounting a three-dimensional sonar device on a tripod support, the bottom of the dam can be scanned in real time to obtain a three-dimensional distribution image of the sediments. By analyzing the intensity and reflection time of the sound wave echoes, the type, thickness, and shape of the sediments can be determined, and further evaluate its impact on the dam structure. This provides important reference data for engineers, helps to formulate effective dredging plans and maintenance strategies, and ensures the safe operation of the dam.

[0004] When hoisting the sonar and the tripod support carrying the sonar to underwater operations, it is necessary to lift the sonar device to the target area through a boom. After the sonar completes the operation, it is still necessary to lift the sonar out of the water for recovery through the boom. During the entire operation process, the setting of the hoisting frame often affects the operation of the sonar.

[0005] Therefore, there is an urgent need for a support for avoiding the interference of a hoisting frame on underwater three-dimensional sonar operations to solve the above problems. Summary of the Invention

[0006] The purpose of the utility model is to overcome the above deficiencies and provide a support for avoiding the interference of a hoisting frame on underwater three-dimensional sonar operations to solve the problems raised in the background technique.

[0007] In order to solve the above technical problems, the technical solution adopted by the utility model is: a support for avoiding the interference of a hoisting frame on underwater three-dimensional sonar operations, including a tripod support, a support foot base is provided at the top of the tripod support, the middle of the support foot base is connected to one end of a support rod, the other end of the support rod is connected to the bottom of a rotating cloud platform fixed platform, and the rotating cloud platform fixed platform is connected to the movable end of a movable boom;

[0008] The movable jib includes a jaw, the back of the tail end of the jaw is connected to one end of an F-shaped jib connecting rod through a rotating bearing, and a telescopic support leg is provided at the other end of the F-shaped jib connecting rod.

[0009] Preferably, the jaw is an openable and closable jaw, and the opening degree of the jaw is adjusted by a lead screw to cooperate with fixed platforms of rotating cloud platforms of different sizes for connection.

[0010] Preferably, a suspension hole for connecting a rope is provided at the suspended end of the central cross bar of the F-shaped jib connecting rod.

[0011] Preferably, the telescopic support leg is a rotary telescopic support leg and can be used to adjust the length to adapt to the height of the support.

[0012] Preferably, the fixed platform of the rotating cloud platform is detachably installed on the support rod, and the fixed platform of the rotating cloud platform has multiple sizes that can be replaced to adapt to sonar devices of different sizes.

[0013] The utility model has the following beneficial effects:

[0014] 1. The jib of the utility model can rotate freely in the vertical plane. When the three-dimensional sonar is hoisted to the bottom of the water, under its own gravity, the jib rotates to the bottom area of the sonar with the hoisting rope, avoiding interference with the sonar operation by the hoisting frame.

[0015] 2. The jaw of the utility model is detachable, and the opening degree of the jaw is adjusted by a lead screw, and can be adapted to fixed platforms of rotating cloud platforms of different models and sizes.

[0016] 3. The movable jib of the utility model can be used as an auxiliary support frame after rotating and landing, further increasing the stability of the sonar when working underwater. Description of the Drawings
