Detailed Description

In order to make the present invention better understood by those skilled in the art, the present invention will be further clearly and completely described below with reference to the accompanying drawings and embodiments. In addition, the features of the embodiments and examples in the present application may be combined with each other without conflict.

In the description of the present invention, it is to be understood that the terms "first", "second", and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implying any number of technical features indicated. Thus, a feature defined as "first," "second," etc. may explicitly or implicitly include one or more of that feature.

As shown in fig. 1, the utility model relates to a marine magnetometer bracket that typical embodiment provided, including magnetometer fixed bolster 1 and the slide 2 of connection in magnetometer fixed bolster 1 bottom, magnetometer fixed bolster 1 include outer frame, transversely set up two or more than two supporting beam 101 that are used for supporting magnetometer 3 in the outer frame, supporting beam 101 middle part is recessed to form arc recess 102, and arc recess 102 upper portion is provided with the connecting piece 103 that is used for fixed magnetometer 3.

As shown in fig. 1, in use, the magnetometer 3 is flatly placed in the magnetometer fixing support 1, the magnetometer 3 is embedded in the arc-shaped groove 102 of the support beam 101, and the magnetometer 3 is fixed by the connecting member 103. The magnetometer fixing support has the function of fixing and protecting the magnetometer 3. The bottom of the magnetometer fixing support 1 is provided with the sliding plate 2, so that the ocean magnetometer and the towing bracket can be conveniently dragged on the seabed, and the dragging resistance is reduced. When dragging, the ship speed should have certain limitation (for example, below 3 knots) to ensure that the towing bracket and the marine magnetometer can sink.

It should be noted that the material adopted by the marine magnetometer bracket of the present invention should be a non-magnetic material. The magnetometer fixing bracket and the sliding plate can be made of non-magnetic alloy materials (preferably, aluminum alloy is used). The whole weight of the towing bracket is ensured to sink when the towing bracket is towed at a low speed.

In a relatively specific embodiment, the connecting member 103 includes an arc-shaped connecting band and connecting lugs with holes disposed at two ends of the arc-shaped connecting band, screw holes are formed at two sides of the top of the arc-shaped groove 102, and the connecting lugs are connected with the supporting beam 101 through bolts. The arc-shaped connecting band can be made of nylon, plastics or aluminum alloy materials, and the connecting lugs and the bolts are made of aluminum alloy materials. The magnetometer 3 is placed behind the arc-shaped groove 102, and the engaging lug is bolted to the support beam 101.

In a preferred embodiment, a semicircular rubber protective cover 4 is fixedly arranged at the front end of the outer frame, a through hole for the front end of the magnetometer 3 to pass through is formed in the middle of the rubber protective cover 4, and the rubber protective cover 4 is used for protecting the magnetometer 3 and preventing the magnetometer 3 from directly impacting an obstacle in the submarine sliding process.

In a relatively specific embodiment, the outer frame includes two frame cross members 104 and two frame longitudinal members 105, the two frame longitudinal members 105 are disposed in parallel, and the two frame cross members 104 are respectively fixedly connected to the front and rear ends of the frame longitudinal members 105. The external frame provided by the embodiment has a simple structure, is easy to manufacture, and can reduce the buoyancy of the external frame, so that the external frame can easily sink to the sea bottom. Furthermore, streamer suspension points may be provided on the outer frame, such as streamer suspension points 106 symmetrically provided at the front ends of the frame rails 105, with which streamers are connected to avoid cable breaks that may occur when towing with cables on marine magnetometers alone.

In a preferred embodiment, a balancing weight 5 is fixed on the inner side surface of the sliding plate 2, and the balancing weight 5 is made of lead blocks, so that the whole bracket and the magnetometer 3 can sink to the seabed more easily.

In a preferred embodiment, the front and rear ends of the sliding plate 2 form inclined surfaces 203 which are inclined upwards, so that the chance that the sliding plate 2 catches on impurities on the seabed during traveling is reduced.
