Description

Technical Field

[0001] The invention relates to the technical field of sonar detectors, and in particular to a multi-probe high-pressure-resistant underwater target sonar detector. Background Art

[0002] In the field of underwater target detection, early detection methods such as visual inspection by divers have many limitations. The detection range of divers is very limited and is severely restricted by factors such as diving depth, underwater visibility, and diving time. It is difficult for divers to carry out their work effectively. The emergence of sonar technology is based on the good propagation characteristics of sound in water. Unlike the propagation of light and radio waves in water, sound waves have relatively little attenuation when propagating in water. Within a certain frequency range, sound waves can propagate a long distance in water, which makes it possible to use sound waves to detect underwater targets. The existing underwater target sonar detector still has the following technical problems when in use, such as: 1. The existing underwater target sonar detector is not effective in removing moisture from the outer skin of the data cable after use. The reason is that although the existing sonar detector uses absorbent cotton to absorb moisture from the outer skin of the data cable, the absorbent cotton gradually decreases its water absorption effect after a period of use due to the long data cable, and gradually cannot fully absorb the moisture on the outer skin of the data cable, so that the moisture on the outer skin of the data cable close to the probe cannot be fully absorbed, which is not conducive to preventing the data cable from being corroded; 2. The existing underwater target sonar detector has low pressure resistance when in use. This is mainly because the depth of the sonar detector is generally deep, which requires the probe of the sonar detector to withstand greater water pressure. If the depth of the water is deep, the probe shell is not enough to withstand the water pressure, which can easily cause the probe to be damaged, making the sonar detector unusable. Therefore, a multi-probe high-pressure underwater target sonar detector is needed to solve the above problems. Summary of the invention

[0013] Compared with the prior art, the invention has the following beneficial effects: after use, the multi-probe high-pressure underwater target sonar detector can completely remove moisture from the outer skin of the data cable, and can avoid the problem of reduced cleaning effect over time. In addition, it can ensure that the sonar probe has a high pressure resistance, so that it can be used in deeper waters: 1. After use, the data cable can be rolled up by rotating the rocker to drive the connecting disk to rotate, and then drive the rope winding shaft to rotate. In the process of rolling up the data cable, the rocker rotates, and the connecting piece can be used to drive the driving frame to move up and down reciprocatingly. In the process of the driving frame moving up and down reciprocatingly, the connecting block can be moved horizontally reciprocatingly through the inclined groove. Since the connecting block is connected to the data cable through the buckle, the data cable running through the buckle position can be driven to move horizontally reciprocatingly. The soft characteristics of the data cable can be used to make the data cable swing, so that part of the water can be thrown off during the rapid swinging of the data cable. In the process of rotating the rope winding shaft, the driving gear drives the transmission gear on the transmission gear kit to rotate at a high speed, so that the fan blade can rotate, so that the air jet hole can spray air at a high speed, and then the remaining water on the data cable can be quickly blown off. By throwing and blowing off, the water on the outer skin of the data cable can be more fully removed, and the problem of reduced cleaning effect with the increase of time can be avoided; 2. After the sonar probe enters the water, the water pressure will first be applied to the protective shell. Since the protective shell is provided with through holes and built-in tubes, the water pressure will cause the piston rod 1 to move in the built-in tube, and the gas in the built-in tube will be pressed to the side tube through the vent pipe, so that the pressure in the side tube increases, thereby moving the piston rod 2 in the side tube, driving the top plate to squeeze the inner wall of the protective shell, and improving the pressure resistance of the protective shell. In addition, the pressure resistance can be further improved by the protective inner shell, so as to ensure that the sonar probe can operate in deeper waters; 3. During the rotation of the fan blades, not only does the outside air enter the inner cavity through the air exchange holes and process holes, and then enter the mesh cover, but it can also absorb the heat generated by the detector body when it is working, which helps to dissipate the heat of the detector body and ensure the stable operation of its internal electronic components.

A data cable 7 is wound around the rope winding shaft 19, and the data cable 7 connects the circuit board in the detector body 1 and the sonar probe 32, and a water removal mechanism is provided on the detector body 1.

[0018] The data line 7 is movably arranged to penetrate the inner cavity, and a float 8 is movably nested on the outer side of the lower part of the data line 7. The water removal mechanism includes a connecting piece 6, a mesh cover 25 and a mounting plate 42. The upper end of the connecting piece 6 is penetrated by the rocker 5 bearing, and the lower end of the connecting piece 6 is connected to a bearing on one side of the mounting plate 42. The other side of the mounting plate 42 is coaxially connected with a drive frame 12, and the drive frame 12 movably penetrates the inclined groove 13. The inclined groove 13 is arranged on the connecting block 14, and the inclined groove 13 passes through both sides of the connecting block 14.

When in use, the connecting piece 6 is driven to move back and forth up and down by rotating the rocker 5. During the up and down reciprocating movement of the connecting piece 6, the driving frame 12 also moves back and forth up and down. Through the connection between the driving frame 12 and the inclined groove 13, the connecting block 14 can be made to move back and forth horizontally. Through the horizontal reciprocating movement of the connecting block 14, the local data line 7 passing through the buckle 15 can be driven to move back and forth horizontally. Since the data line 7 is made of soft material, it will swing with the local data line 7 passing through the buckle 15 as the endpoint. When the data line 7 swings quickly, it can throw off most of the moisture on its outer surface. In addition, when the rocker 5 is rotated, it drives During the rotation of the rope shaft 19, the driving gear 22 will drive the transmission gear on the transmission gear kit 23 to rotate at a high speed. During the high-speed rotation of the transmission gear, the shaft rod drives the fan blade 24 to rotate at a high speed, which will not only suck the outside air into the mesh cover 25, but also absorb the heat generated by the detector body 1 when it is working into the mesh cover 25, and then transport it to the air collecting ring 17 through the air pipe 26. The air entering the air collecting ring 17 is ejected from the air jet hole 18 at a high speed, thereby blowing off the remaining moisture on the data cable 7. The moisture on the outer skin of the data cable 7 is removed by the above method, which can avoid the problem that the moisture absorption effect gradually decreases as the moisture absorption time of the absorbent cotton increases due to the use of absorbent cotton in the past. The transmission gear kit 23 is composed of a transmission gear and a shaft rod.The two are key-connected, and the gear ratio of the transmission gear and the driving gear 22 is not greater than 0.3, which is used to realize that the low-speed rotation of the driving gear 22 drives the high-speed rotation of the transmission gear. The driving frame 12 is an N-shaped structure, and the driving frame 12 is arranged parallel to the slide 16. The mesh cover 25 is only provided with hollow holes on the surface facing the air exchange hole 11, and the distance between the hollow holes and the fan blades 24 is less than the distance between the hollow holes and the connection part of the air pipe 26 and the mesh cover 25.

[0020] The pressure-resistant mechanism includes a protective shell 9, a top plate 39 and a connecting rod 41. The outer side of the protective shell 9 is evenly distributed with through holes 33, and the inner side of the protective shell 9 at the through hole 33 is provided with an integrated built-in tube 34, one end of a piston rod 35 is seamlessly slidably connected in the built-in tube 34, and the other end of the piston rod 35 seamlessly slides through the end of the built-in tube 34 away from the through hole 33, connecting frames 36 are distributed at equal angles on the built-in tube 34, and each connecting frame 36 is fixedly penetrated with a side tube 37, one end of a piston rod 38 is seamlessly slidably connected to the inner side of the open end of the side tube 37, and the non-open end of the side tube 37 is The mouth end is connected to the end of the built-in tube 34 away from the through hole 33 through the vent pipe 40, the top plate 39 is movably penetrated by the corresponding built-in tube 34, and the outer side of the top plate 39 faces the inner side of the protective shell 9, and the inner side of the top plate 39 is fixedly connected with the other end of the corresponding piston rod 28, the inner side of the protective shell 9 is connected to the outer side of the protective inner shell 30 through the support rods 29 evenly distributed in the longitudinal direction, and the inner side surface of the protective inner shell 30 is connected to the mounting shell 31 through the connecting rods 41 evenly distributed in the transverse direction, the sonar probe 32 is installed on the mounting shell 31, and the lower end of the data line 7 is sealed and penetrates the protective shell 9, the protective The inner shell 30 and the mounting shell 31 are connected to the sonar probe 32. After the sonar probe 32 enters the water, the protective outer shell 9 is the first to contact with the water, so that the protective outer shell 9 is the first to bear the water pressure. When the protective outer shell 9 is subjected to the water pressure, water enters the through hole 33 and the built-in tube 34, which causes the piston rod 1 35 to also bear the water pressure, so that the piston rod 1 35 moves toward the inside of the built-in tube 34, squeezing the air in the built-in tube 34, so that the air in the built-in tube 34 enters the side tube 37 through the vent pipe 40, thereby increasing the air pressure in the side tube 37, thereby causing the piston rod 2 38 in the side tube 37 to move. The top plate 39 gradually squeezes the inner side of the protective outer shell 9, thereby improving the pressure resistance of the protective outer shell 9. At the same time, the protective inner shell 30 connected by the support rod 29 can further improve the pressure resistance of the sonar probe 32, ensuring that the multiple sonar probes 32 installed on the mounting shell 31 can operate in deeper waters. The protective outer shell 9, the protective inner shell 30 and the mounting shell 31 are all spheres, and the protective outer shell 9, the protective inner shell 30 and the mounting shell 31 are concentrically arranged, and the axis of the lower end of the data cable 7 passes through the center of the three spheres.
