Description

Technical Field

[0001] The present invention relates to the technical field of sonar detectors, and specifically 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 very difficult for divers to carry out effective work.

[0003] The emergence of sonar technology is based on the good propagation characteristics of sound in water. Different from the propagation of light and radio waves in water, the attenuation of sound waves during propagation in water is relatively small. Within a certain frequency range, sound waves can propagate a relatively long distance in water, which makes it possible to use sound waves to detect underwater targets.

[0004] When the existing underwater target sonar detectors are in use, there are still the following technical problems, such as:

[0005] 1. After the existing underwater target sonar detectors are out of use, the effect of removing moisture on the outer skin of the data cable is not good. The reason is that although the existing sonar detectors use absorbent cotton to absorb the moisture on the outer skin of the data cable, due to the long length of the data cable, the water absorption effect of the absorbent cotton gradually decreases after being used for a period of time, and then it gradually cannot fully absorb the moisture on the outer skin of the data cable, so that the moisture on the outer skin near the probe part of the data cable cannot be fully absorbed, which is not conducive to preventing the data cable from being corroded.

[0006] 2. When the existing underwater target sonar detectors are in use, the pressure resistance ability is relatively low. The main reason is that the depth at which the sonar detectors are used is generally relatively deep, which makes the probes of the sonar detectors need to bear a large water pressure. If the diving depth is relatively deep and the probe housing is not sufficient to bear the water pressure, it is easy to cause the probe to be damaged, and then the sonar detector cannot be used.

[0007] Therefore, a multi-probe high-pressure-resistant underwater target sonar detector is needed to solve the above problems. Summary of the Invention

[0008] The purpose of the present invention is to provide a multi-probe high-pressure-resistant underwater target sonar detector to solve the problems that the existing underwater target sonar detectors have a poor effect when removing moisture on the outer skin of the data cable and a relatively low probe pressure resistance ability as mentioned in the above background art.

[0009] To achieve the above purpose, the present invention provides the following technical solutions:

[0010] A multi-probe high-compression underwater target sonar detector, comprising a detector body, a connection disk, a water removal mechanism and a compression resistance mechanism. The upper surface of the detector body is provided with a display screen and a controller, and the detector body is also provided with an inner cavity. The open end of the inner cavity is provided with a partition one and a partition two, and one end of a rope winding shaft is connected to the inner cavity in a bearing manner at the closed end. The other end of the rope winding shaft sequentially passes through the partition one and the partition two in a bearing manner and is coaxially and fixedly connected to one side of the connection disk. A rocker is installed at an eccentric position on the other side of the connection disk. A handle is provided on the front side of the detector body, and a process hole penetrating through the inner cavity is provided on the rear side of the detector body. A data cable is wound around the rope winding shaft, and the data cable connects the circuit board and the sonar probe inside the detector body. A water removal mechanism is provided on the detector body, and a compression resistance mechanism is provided outside the sonar probe.

[0011] Preferably, the data cable is movably arranged through the inner cavity, and a float is movably nested on the outer side of the lower part of the data cable.

[0012] Preferably, the water removal mechanism comprises a connecting piece, a mesh cover and a mounting disk. The upper end of the connecting piece is penetrated by the rocker in a bearing manner, and the lower end of the connecting piece is connected to one side of the mounting disk in a bearing manner. A driving frame is coaxially connected to the other side of the mounting disk, and the driving frame movably penetrates through an inclined slot. The inclined slot is arranged on the connecting block and penetrates through both sides of the connecting block. A buckle ring is installed on one side of the connecting block, and the data cable movably penetrates through the buckle ring. The upper surface of the connecting block is installed on the lower surface of the slider, and the slider is slidably connected to the chute. The chute is installed on the lower surface of the detector body, and air exchange holes penetrating through both sides of the inner cavity are provided at the closed end of the upper inner cavity of the detector body. A driving gear and a transmission gear set are arranged between the partition one and the partition two, and the driving gear is key-connected to the outer side of the rope winding shaft. The driving gear is partially engaged with the transmission gear on the transmission gear set, and one end of the shaft rod part on the transmission gear set is connected to the partition two in a bearing manner. The other end of the shaft rod part on the transmission gear set penetrates through the partition one in a bearing manner, and fan blades are equiangularly installed on the outer side of the part of the shaft rod penetrating through the partition one. The fan blades are arranged inside the mesh cover, and the mesh cover is installed on the partition one. The mesh cover is connected to the inside of the air collecting ring through an air pipe, and the air collecting ring is installed on the lower surface of the detector body. The data cable movably penetrates through the air collecting ring, and inclined downward jet holes are equiangularly arranged on the inner side of the air collecting ring.

[0013] Preferably, the transmission gear set is composed of a transmission gear and a shaft rod, and the two are key-connected. The tooth number ratio of the transmission gear to the driving gear is not greater than 0.3, so as to realize the low-speed rotation of the driving gear driving the high-speed rotation of the transmission gear.

[0014] Preferably, the driving frame is of an n-shaped structure and is arranged parallel to the chute.

[0015] Preferably, the wire mesh cover is provided with hollow holes only on the surface facing the air exchange holes, and the distance between the hollow holes and the fan blades is less than the distance between the hollow holes and the connection part of the air delivery pipe and the wire mesh cover.

[0016] Preferably, the compression resistance mechanism includes a protective outer shell, a top plate and a connecting rod. The outer side of the protective outer shell is evenly distributed with through holes, and an inner built-in pipe integrated with it is arranged on the inner side of the protective outer shell at the position of the through holes. One end of a first piston rod is slidably connected in the built-in pipe without clearance, and the other end of the first piston rod slidably penetrates through the end of the built-in pipe far from the through hole without clearance. Connecting frames are evenly distributed at equal angles on the built-in pipe, and each connecting frame is fixedly penetrated with a side pipe. One end of a second piston rod is slidably connected in the inner side of the open end of the side pipe without clearance, and the non-open end of the side pipe is communicated with the end of the built-in pipe far from the through hole through a ventilation pipe. The top plate is movably penetrated by the corresponding built-in pipe, and the outer side of the top plate faces the inner side of the protective outer shell. The inner side of the top plate is fixedly connected to the other end of the corresponding second piston rod. The inner side of the protective outer shell is connected to the outer side of the protective inner shell through longitudinally evenly distributed support rods, and the inner side of the protective inner shell is connected to the mounting shell through horizontally evenly distributed connecting rods. The sonar probe is installed on the mounting shell, and the lower end of the data line sequentially penetrates through the protective outer shell, the protective inner shell and the mounting shell in a sealed manner and is connected to the sonar probe.

[0017] Preferably, the protective outer shell, the protective inner shell and the mounting shell are all spherical, and the protective outer shell, the protective inner shell and the mounting shell are concentrically arranged, and the axis of the lower end of the data line penetrates through the centers of the three.

[0018] Preferably, the top plate is of an arc surface structure, and its radian matches the inner side of the protective outer shell at the corresponding position.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows: After the multi-probe high-compression underwater target sonar detector is used, the water on the outer skin of the data line can be relatively thoroughly removed, and the problem that the removal effect decreases with the passage of time can be avoided. In addition, the sonar probe can be ensured to have a high compression resistance, so that it can be used in deeper waters.

[0020] 1. After use, rotate the rocker to drive the connection plate to rotate, and then drive the rope winding shaft to rotate, so as to wind up the data cable. During the process of winding up the data cable, due to the rotation of the rocker, the connecting piece can be used to drive the driving frame to move up and down reciprocally. During the process of the driving frame moving up and down reciprocally, the connecting block can be horizontally reciprocated through the inclined groove. Since the connecting block is connected to the data cable through a buckle ring, the data cable passing through the position of the buckle ring can be driven to move horizontally reciprocally. Utilizing the flexible characteristic of the data cable, the data cable can be swung, and thus, during the process of the rapid swing of the data cable, a part of the water can be shaken off. During the process of the rope winding shaft rotating, the driving gear drives the transmission gear on the transmission gear set to rotate at a high speed, and thus the fan blades can be rotated, so that the air injection holes can eject air at a high speed, and thus the remaining water on the data cable can be quickly blown off. Through the ways of shaking off and blowing off, the water on the outer skin of the data cable can be more thoroughly removed, and the problem that the cleaning effect decreases with the passage of time can be avoided;

[0021] 2. After the sonar probe enters the water, the water pressure will be first applied to the protective shell. Since through holes and an internal pipe are provided on the protective shell, the water pressure will cause the first piston rod to move in the internal pipe, and the gas in the internal pipe will be pressed towards the side pipe through the air pipe, so that the pressure in the side pipe increases, thereby causing the second piston rod in the side pipe to move, driving the top plate to squeeze the inner wall of the protective shell, improving the compressive degree of the protective shell. In addition, the compressive performance can be further improved through the inner protective shell, so as to ensure that the sonar probe can operate in deeper waters;

[0022] 3. During the rotation of the fan blades, not only the outside air can enter the inner cavity through the air exchange holes and the process holes and then enter the mesh cover, but also the heat generated during the operation of the detector body can be absorbed during this process, which helps to dissipate the heat of the detector body and ensure the stable operation of the internal electronic components.

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0035] Please refer to Figures 1-10 , the present invention provides the following technical solutions:

[0036] Embodiment 1: To solve the problem that the effect of removing moisture from the data cable 7 is not good when the underwater target sonar detector is used up in the past, the following technical solution is provided. Specifically, a multi-probe high-pressure-resistant underwater target sonar detector includes a detector body 1, a connection disk 27, a water removal mechanism and a pressure-resistant mechanism. A display screen 2 and a controller 3 are arranged on the upper surface of the detector body 1, and an inner cavity is also arranged on the detector body 1. A partition plate 20 and a partition plate 21 are arranged at the open end of the inner cavity, and one end of a rope winding shaft 19 is connected by a bearing to the closed end of the inner cavity. The other end of the rope winding shaft 19 sequentially passes through the partition plate 20 and the partition plate 21 by bearings and is coaxially and fixedly connected to one side of the connection disk 27. A rocker 5 is installed at an eccentric position on the other side of the connection disk 27. A handle 4 is arranged on the front side of the detector body 1, and a process hole 10 penetrating through the inner cavity is arranged on the rear side of the detector body 1. 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. A water removal mechanism is arranged on the detector body 1.

[0037] The data cable 7 is movably arranged through the inner cavity, and a float 8 is movably nested outside the lower part of the data cable 7. The water removal mechanism includes a connecting piece 6, a wire mesh cover 25 and a mounting disc 42. The upper end of the connecting piece 6 is penetrated by a bearing of the rocker 5, and the lower end of the connecting piece 6 is bearing-connected to one side of the mounting disc 42. The other side of the mounting disc 42 is coaxially connected with a driving frame 12, and the driving frame 12 movably penetrates through an inclined slot 13. The inclined slot 13 is arranged on the connecting block 14 and penetrates through both sides of the connecting block 14. A buckle 15 is installed on one side of the connecting block 14, and the buckle 15 is movably penetrated by the data cable 7. The upper surface of the connecting block 14 is installed on the lower surface of the slider 28, and the slider 28 is slidably connected to the chute 16. The chute 16 is installed on the lower surface of the detector body 1, and an air exchange hole 11 penetrating both sides of the inner cavity is arranged at the closed end of the upper inner cavity of the detector body 1. A driving gear 22 and a transmission gear set 23 are arranged between the partition plate one 20 and the partition plate two 21. The driving gear 22 is key-connected to the outside of the rope winding shaft 19. The driving gear 22 is meshed with the transmission gear part on the transmission gear set 23. One end of the shaft rod part on the transmission gear set 23 is bearing-connected to the partition plate two 21. The other end of the shaft rod part on the transmission gear set 23 is bearing-penetrated through the partition plate one 20. A fan blade 24 is equiangularly installed on the outside of the part of the shaft rod penetrating through the partition plate one 20. The fan blade 24 is arranged inside the wire mesh cover 25, and the wire mesh cover 25 is installed on the partition plate one 20. The wire mesh cover 25 is connected to the inside of the air collecting ring 17 through an air delivery pipe 26. The air collecting ring 17 is installed on the lower surface of the detector body 1. The air collecting ring 17 is movably penetrated by the data cable 7. Inclined downward jet holes 18 are equiangularly arranged inside the air collecting ring 17. During use, by rotating the rocker 5 to drive the connecting piece 6 to move up and down reciprocally. During the process of the connecting piece 6 moving up and down reciprocally, the driving frame 12 also moves up and down reciprocally. Through the connection between the driving frame 12 and the inclined slot 13, the connecting block 14 can be made to move horizontally reciprocally. Through the horizontal reciprocal movement of the connecting block 14, the partial data cable 7 penetrating through the buckle 15 can be driven to move horizontally reciprocally. Since the data cable 7 is made of a soft material, it will swing with the partial data cable 7 penetrating through the buckle 15 as the end point. When the data cable 7 swings rapidly, most of the water on its outer surface can be shaken off. In addition, during the process of rotating the rocker 5 to drive the rope winding shaft 19 to rotate, the driving gear 22 will drive the transmission gear on the transmission gear set 23 to rotate at a high speed. During the process of the transmission gear rotating at a high speed, the shaft rod drives the fan blade 24 to rotate at a high speed, which will not only suck the outside air into the wire mesh cover 25, but also absorb the heat generated during the operation of the detector body 1 into the wire mesh cover 25, and then transport it to the air collecting ring 17 through the air delivery pipe 26. The air entering the air collecting ring 17 is ejected from the jet holes 18 at a high speed, so as to blow off the remaining water on the data cable 7. By removing the water on the outer skin of the data cable 7 in the above way, the problem that the water absorption effect gradually decreases with the increase of the water absorption time of the absorbent cotton in the past can be avoided. The transmission gear set 23 is composed of a transmission gear and a shaft rod.And the two are key-connected, and the tooth number ratio of the transmission gear to the driving gear 22 is not greater than 0.3, which is used to realize the low-speed rotation of the driving gear 22 to drive the high-speed rotation of the transmission gear. The driving frame 12 is of an n-shaped structure, and the driving frame 12 is arranged parallel to the sliding groove 16. The wire mesh cover 25 is provided with hollow holes only on the surface facing the air exchange hole 11, and the distance between the hollow holes and the fan blade 24 is less than the distance between the hollow holes and the connection part of the air delivery pipe 26 and the wire mesh cover 25.,

[0038] Embodiment 2: To solve the problems that the underwater target sonar detector in the past had insufficient compressive performance and was not convenient for operating in deeper waters when in use, the following technical solutions are provided. Specifically, a compressive mechanism is arranged outside the sonar probe 32.

[0039] The pressure-resistant mechanism includes a protective housing 9, a top plate 39 and a connecting rod 41. Through holes 33 are evenly distributed on the outer side of the protective housing 9, and an inner tube 34 integrated with it is provided on the inner side of the protective housing 9 at the position of the through holes 33. One end of a first piston rod 35 is slidably connected to the inner tube 34 without clearance, and the other end of the first piston rod 35 slidably penetrates through the end of the inner tube 34 away from the through holes 33 without clearance. Connecting frames 36 are evenly distributed on the inner tube 34 at equal angles, and a side tube 37 is fixedly penetrated through each connecting frame 36. One end of a second piston rod 38 is slidably connected to the inner side of the open end of the side tube 37 without clearance, and the non-open end of the side tube 37 is connected to the end of the inner tube 34 away from the through holes 33 through a ventilation pipe 40. The top plate 39 is movably penetrated by the corresponding inner tube 34, and the outer side of the top plate 39 faces the inner side of the protective housing 9. The inner side of the top plate 39 is fixedly connected to the other end of the corresponding second piston rod 38. The inner side of the protective housing 9 is connected to the outer side of the inner protective shell 30 through longitudinally evenly distributed support rods 29, and the inner side of the inner protective shell 30 is connected to the mounting shell 31 through transversely evenly distributed connecting rods 41. A sonar probe 32 is installed on the mounting shell 31, and the lower end of the data line 7 sequentially penetrates through the protective housing 9, the inner protective shell 30 and the mounting shell 31 in a sealed manner and is connected to the sonar probe 32. After the sonar probe 32 enters the water, the first part to contact the water is the protective housing 9, so that the protective housing 9 bears the water pressure first. During the process of the protective housing 9 bearing the water pressure, after the water enters the through holes 33 and the inner tube 34, the first piston rod 35 will also bear the water pressure, so that the first piston rod 35 moves towards the inside of the inner tube 34, squeezing the air in the inner tube 34, and making the air in the inner tube 34 enter the side tube 37 through the ventilation pipe 40, increasing the air pressure in the side tube 37, and then causing the second piston rod 38 in the side tube 37 to move, making the top plate 39 gradually squeeze the inner side of the protective housing 9, thereby improving the pressure resistance of the protective housing 9. At the same time, the inner protective shell 30 connected by the support rods 29 can further improve the pressure resistance performance of the sonar probe 32, ensuring that multiple sonar probes 32 installed on the mounting shell 31 can operate in deeper waters. The protective housing 9, the inner protective shell 30 and the mounting shell 31 are all spherical, and the protective housing 9, the inner protective shell 30 and the mounting shell 31 are concentrically arranged, and the axis of the lower end of the data line 7 penetrates through the centers of the three spheres.
