AI Technical Summary
Seaweed floating or suspended in the ocean, abandoned fishing nets and net ropes are often wrapped around the sonar probe, causing posture changes, data acquisition effects to be affected, and may damage the probe.
A sonar probe protection device is designed, including a vertical barrier component and a support hook in front of the sonar probe. The barrier component adopts a ladder structure, and the water inlet depth is deeper than the sonar probe. The support hook can hook seaweed, abandoned fishing nets and net ropes to prevent them from entangling.
It effectively avoids the sonar probe being wrapped by seaweed, abandoned fishing nets and net ropes, reduces water noise interference, extends the service life of the sonar probe, and simplifies the measurement process.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of marine surveying and mapping, and particularly relates to a sonar probe protection device. Background Art
[0002] At present, various marine development activities such as offshore oil, offshore wind power, and offshore artificial fish reefs all require marine surveying and mapping means to analyze the seabed topography and the distribution of seabed obstacles. Most of these surveying and mapping means use acoustic detection sonars, and the sonars need to be immersed in seawater in a fixed installation or towing manner for work. However, various seagrasses and discarded fishing nets and ropes floating or suspended in the ocean often entangle the sonar probe, causing a drastic change in the sonar attitude and affecting the data acquisition effect; the entanglement of seagrasses and the like on the sonar probe will also generate more underwater acoustic noise, interfering with data analysis. At the same time, the cleaning of seagrasses is time-consuming and laborious, and the discarded ropes are more likely to scrape the sonar probe or even damage the probe. In view of the above situation, a sonar probe protection device is proposed. Content of the Utility Model
[0003] Aiming at the problems existing in the prior art, the utility model provides a sonar probe protection device, which can block seagrasses and discarded fishing nets and ropes in front of the sonar probe, avoiding the sonar probe from being entangled.
[0004] The utility model is realized as follows: A sonar probe protection device is arranged in front of the sonar probe, including a blocking member fixedly connected to the ship's side and vertically arranged. The water depth of the blocking member is deeper than that of the sonar probe, and a towing hook is arranged in front of the bottom. The towing hook is provided with a bottom rod perpendicularly and fixedly connected to the front side of the blocking member, and an upward hook head is arranged at the front end of the bottom rod.
[0005] The device is arranged 4 - 5m in front of the sonar probe, and the water depth of the blocking member is 1m deeper than that of the sonar probe.
[0006] The upper end of the blocking member is provided with a hook that fits the ship's side, and the lower end is provided with a fixed connection ring.
[0007] The blocking member adopts a ladder structure, provided with a ladder frame parallel to the side of the ship's hull, and a plurality of evenly distributed ladder steps are arranged on the ladder frame.
[0008] The fixed connection ring adopts a stainless steel ring.
[0009] Advantages and technical effects of the present utility model: The seagrass, discarded fishing nets and ropes are blocked in front of the sonar probe by the blocking component, and the seagrass, discarded fishing nets and ropes are hooked by the hook to prevent them from coming out, so that the sonar probe can be successfully prevented from being entangled by the seagrass, discarded fishing nets and ropes. Moreover, the structure of the present utility model is simple, safe and reliable, easy to manufacture and install, can be applied to various measuring ships, and does not need to be removed during measurement, which can avoid the problems of shortened service life and wasted measurement time caused by frequent disassembly of the device.

[0011] In the figure, 1, hook; 2, ladder frame; 3, ladder step; 4, bottom rod; 5, hook head; 6, fixed connection ring. Detailed Implementation Manner
[0012] In order to make the purpose, technical solution and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.
[0013] Please refer to Figure 1 , a sonar probe protection device, which is arranged in front of the sonar probe, includes a blocking component fixedly connected to the ship's side and vertically arranged, the water depth of the blocking component is deeper than that of the sonar probe, and a hook is arranged in front of the bottom, the hook is provided with a bottom rod 4 vertically fixedly connected to the front side of the blocking component, and a hook head 5 is arranged upward at the front end of the bottom rod 4.
[0014] A more preferred solution is as follows:
[0015] The device is arranged 4 - 5 m in front of the sonar probe, and the water depth of the blocking component is 1 m deeper than that of the sonar probe.
[0016] The upper end of the blocking component is provided with a hook 1 that fits the ship's side, and the lower end is provided with a fixed connection ring 6.
[0017] The blocking component adopts a ladder structure, is provided with a ladder frame 2 parallel to the side of the ship's body, and a plurality of evenly distributed ladder steps 3 are arranged on the ladder frame 2, with large structural stiffness and not easy to deform.
[0018] The fixed connection ring 6 is made of a stainless steel ring, which is stainless and corrosion-resistant.

[0020] Application of the utility model:
[0021] During measurement, the device is installed 4 to 5 m in front of the sonar. By using the hook, it can be conveniently and quickly moved back and forth, and then the device is fixed to the measurement ship by three steel wires, namely the front, rear, and bottom wires, which are connected to the fixed connection ring. The installation position can be adjusted conveniently. After the device is installed, the sonar probe has never been entangled by seaweeds, discarded fishing nets, or net ropes, and the use effect is very good.
[0022] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model.
