Description

Technical Field

[0001] This invention relates to the field of sonar technology, and in particular to a multifunctional side-sliding sonar device. Background Technology

[0002] Sonar is a technology that utilizes the propagation and reflection characteristics of sound waves in water to navigate and measure distances through electroacoustic conversion and information processing. It also refers to electronic devices that use this technology to detect (presence, location, properties, direction of movement, etc.) and communicate with underwater targets. It is one of the most widely used and important devices in underwater acoustics. In modern ship applications, sonar is usually fixedly installed at the bottom of the bow or stern. This means that replacing or repairing the sonar requires maintenance personnel to enter the water or raise the ship, making replacement or repair difficult. To solve this problem, some sonar systems adopt a movable installation method. For example, the utility model patent with authorization announcement number CN220786055U, entitled "A Bottom-Mounted Sonar Installation Device," uses a track, carriage, and motor-driven gear and rack drive to freely switch the sonar equipment between the bottom of the ship and one side of the hull. This allows for a multi-position design where the equipment works at the bottom and is maintained at the side, creating a good space for later maintenance and enabling free and efficient maintenance of the sonar equipment.

[0003] While the aforementioned utility model allows the sonar to move freely between the hull and one side of the ship, it cannot immediately move the sonar to the side of the hull when it is about to be hit, resulting in damage. Therefore, it is necessary to invent a multifunctional side-sliding sonar device that can quickly move the sonar to the side of the hull when it is about to be hit, thus avoiding a collision and effectively protecting the sonar. Summary of the Invention

[0004] To address the above problems, this invention proposes a multifunctional side-sliding sonar device, the technical solution of which is as follows:

[0005] A multifunctional side-sliding sonar device includes a slide rail rack, a moving frame, a drive gear, and a sonar; the slide rail rack is fixedly installed on the bottom of the hull and connects to both sides of the hull; the moving frame is slidably installed on the slide rail rack; the hull is equipped with a power unit for driving the moving frame to move quickly.

[0006] A support frame is slidably and elastically mounted within the movable frame, and the drive gear is rotatably mounted on the support frame. The sonar is fixedly mounted on the movable frame. A mounting frame is fixedly mounted on the movable frame, and several contact rods are slidably and elastically mounted within the mounting frame. Each contact rod has a touch switch mounted at its outermost end, and the touch switch is electrically connected to the power device. A limit lever is rotatably mounted on the mounting frame, and the limit lever intermittently engages the support frame, causing the drive gear to intermittently mesh with the slide rail rack. The limit lever and the contact rods are linked by a linkage mechanism.

[0007] Furthermore, the power unit includes winches, with winches installed on both sides of the hull, and the wire rope of each winch is fixedly connected to the moving frame.

[0008] Furthermore, a tool holder is fixedly installed at the location of the winch on the hull, and the tool holder has a wire rope through hole corresponding to the wire rope; several cutting blades are provided below the wire rope through hole; each cutting blade is fixedly installed on an L-shaped rod, the L-shaped rod is rotatably installed on the tool holder and elastically connected to the tool holder; a limiting block is fixedly provided on the tool holder to limit the L-shaped rod.

[0009] Furthermore, the linkage mechanism includes a linkage rack, a linkage gear, a transition gear, a limiting gear, and a magnet; each contact rod corresponds to a linkage rack slidably mounted on the mounting frame, and a magnet is correspondingly mounted on the facing surfaces of the contact rod and the linkage rack; each linkage rack meshes with a linkage gear rotatably mounted on the mounting frame; the linkage gear meshes with a transition gear rotatably mounted on the mounting frame; the limiting gear is rotatably mounted on the mounting frame and meshes with the linkage gear; the limiting lever is fixedly mounted on the limiting gear; a stop block is fixedly provided on the mounting frame to block the linkage rack.

[0010] Furthermore, push rods are installed on both sides of the hull for intermittently actuating the support frame.

[0011] Furthermore, a servo motor is fixedly mounted on the support frame, and the output end of the servo motor is coaxially and fixedly connected to the drive gear.

[0012] Furthermore, a cutting blade is slidably mounted axially in the teeth of the drive gear, and the cutting edge and end side of the cutting blade extend out of the teeth of the drive gear; the support frame is provided with several protrusions on both sides of the drive gear, and the protrusions on both sides of the drive gear are staggered relative to each other, and the cutting blade alternately contacts the protrusions on both sides.

[0013] Furthermore, a connecting plate is provided on each side of the drive gear, and the end of the cutting blade is fixedly mounted on the corresponding connecting plate; the connecting plate is provided with a number of protrusions that intermittently contact the protrusions.

[0014] Furthermore, the cable used to supply power to the electrical components on the moving frame is fixed together with the wire rope of the winch and moves with the wire rope. The cable and the wire rope are wrapped with a flexible armor layer, and the cable end enters the moving frame to connect with the electrical components.

[0015] Furthermore, several wire rope pulleys are installed along the slide rail rack on the hull to guide the wire rope of the winch.

[0037] Example:

[0038] like Figures 1-5 As shown, a multifunctional side-sliding sonar device includes a winch 1, a slide rail rack 2, a moving frame 3, a drive gear 5, and a sonar 10. A winch 1 is installed on each side of the hull 26. The slide rail rack 2 is fixedly installed on the bottom of the hull 26 and connects the two winches 1. Four rollers 4 are rotatably mounted on the moving frame 3 and slidably mounted on the slide rail rack 2 via the rollers. Several wire rope pulleys 25 are installed along the slide rail rack 2 on the hull 26, and the wire rope of each winch 1 is in a taut state. The sonar 10 is fixedly mounted on the wire rope pulley 25 and guided by the wire rope pulley 25, with the rope end fixedly connected to the movable frame 3. A mounting frame 11 is fixedly installed on the movable frame 3, and the sonar 10 is fixedly mounted on the movable frame 3 and located within the mounting frame 11. A support frame 7 slides within the movable frame 3, and the support frame 7 is elastically connected to the movable frame 3 via a tension spring. A drive gear 5 is rotatably mounted on the support frame 7. A servo motor 6 is fixedly mounted on the support frame 7, and the output end of the servo motor 6 is coaxially fixedly connected to the drive gear 5. It should be noted that the multifunctional side-sliding sonar device of this embodiment can be installed at the bow or stern of a ship, and the slide rail rack 2 is adapted to fit the curvature and shape of the bow or stern.

[0039] like Figures 6-10 As shown, the mounting frame 11 has three sub-supports 1101 pointing in different directions fixedly installed inside. Each sub-support 1101 has a contact rod 12 slidably installed inside, and the contact rod 12 is elastically connected to the sub-support 1101 through a tension spring. Each contact rod 12 has a touch switch 13 installed at its outermost end, and the touch switch 13 is electrically connected to the winch 1. Each contact rod 12 corresponds to a linkage rack 14, and the linkage rack 14 is collinear with the corresponding contact rod 12 and slidably installed on the sub-support 1101. Magnets 19 are installed on the facing surfaces of the contact rod 12 and the linkage rack 14. Each linkage rack 14 is connected to a linkage that is rotatably installed on the mounting frame 11. Gear 15 meshes; all three linkage gears 15 mesh with transition gear 16 rotatably mounted on mounting frame 11; limit gear 17 rotatably mounted on mounting frame 11 and meshes with transition gear 16; limit lever 18 is fixedly mounted on limit gear 17 via two connecting rods, and the mounting frame 11 has two arc-shaped sliding grooves 1102 corresponding to the connecting rod of limit lever 18, with the connecting rod located in the arc-shaped sliding grooves 1102, thereby limiting the rotation angle of limit lever 18; limit lever 18 intermittently locks support frame 7; a stop block 1103 is fixedly provided on the sub-bracket 1101, the stop block 1103 is located between contact rod 12 and linkage rack 14, and is used to block linkage rack 14.

[0040] like Figure 3As shown, push rods 20 are installed at the locations of the winches 1 on both sides of the hull 26; when the moving frame 3 moves to the side of the hull 26, the push rods 20 can pass through the moving frame 3 and move the support frame 7.

[0041] like Figure 6 and Figures 11-12 As shown, each tooth of the drive gear 5 has a groove 501 extending radially along the drive gear 5. A cutting blade 8 is slidably mounted in the groove 501 along the axial direction of the drive gear 5, and the cutting edge of the cutting blade 8 can extend radially out of the groove 501 along the drive gear 5. The width of the cutting blade 8 is greater than the width of the tooth of the drive gear 5, which allows the end side of the cutting blade 8 to extend axially out of the groove 501 along the drive gear 5. A connecting plate 9 is provided on each side of the drive gear 5, and the end side of the cutting blade 8 is fixedly mounted on the corresponding connecting plate 9. A protrusion extending outward along the axial direction of the drive gear 5 is provided at the connection between the connecting plate 9 and the cutting blade 8. Several protrusions 701 are evenly distributed along the circumference on both sides of the drive gear 5 in the support frame 7, and the protrusions 701 on both sides of the drive gear 5 are staggered relative to each other. The two connecting plates 9 alternately contact the protrusions 701 on their respective sides.

[0042] like Figure 3 and Figures 13-14 As shown, a knife holder 21 is fixedly installed on the hull 26 at the location of the winch 1. The knife holder 21 has a wire rope through hole 2101 corresponding to the wire rope of the winch 1. Three cutting blades 24 are provided below the wire rope through hole 2101. Each cutting blade 24 is fixedly installed on the long end of an L-shaped rod 22. The corner end of the L-shaped rod 22 is rotatably installed on the knife holder 21 through a pin, and the short end of the L-shaped rod 22 is elastically connected to the knife holder 21 through a tension spring. A limiting block 23 is fixedly installed on the knife holder 21 above the corner end of the L-shaped rod 22. The three cutting blades 24 are evenly distributed in a circle, and the lower blades of the three cutting blades 24 are flared, which facilitates cutting debris on the wire rope. The upper part of the long end of the L-shaped rod 22 is smooth and arc-shaped, which is conducive to the wire rope passing through from top to bottom.

[0043] The cable supplying power to the electrical components on the mobile frame 3 is fixed together with the wire rope of the winch 1 and moves with the wire rope. The cable and the wire rope are wrapped with a flexible armor layer, and the cable end enters the mobile frame 3 to connect with the electrical components.

[0044] This embodiment also includes a control terminal, which is electrically connected to the winch 1, servo motor 6, sonar 10, and touch switch 13, and is used to control the operation of the entire device.

[0045] The operation method of the multi-functional side-sliding sonar device in this embodiment is as follows:

[0046] Under normal circumstances, the limit lever 18 will lock the support frame 7 (the tension spring between the support frame 7 and the moving frame 3 will be stretched), the drive gear 5 will mesh with the slide rail rack 2, the power mechanism of the winch 1 will be shut off and the wire rope drum will be in a free state; the servo motor 6 will be started, driving the drive gear 5 to rotate, and the moving frame 3 will move along the slide rail rack 2 to the working position of the sonar 10 as needed. After the moving frame 3 arrives, the servo motor 6 will be shut off, the power mechanism of the winch 1 will be started, so that the wire ropes on both sides of the moving frame 3 will be taut, the moving frame 3 will be fixed, and the sonar 10 will start working.

[0047] Sonar 10 detects obstacles in the water. When sonar 10 detects an obstacle and the distance between it and the obstacle is less than a set value, the control terminal controls the start of winch 1. The wire rope pulls the moving frame 3 to move away from the obstacle, so that the moving frame 3 avoids the obstacle (one winch 1 retracts the rope and the other winch 1 releases the rope).

[0048] If the sonar 10 fails to detect the obstacle in time or there is no time to avoid it, the contact rod 12 will come into contact with the obstacle in the water. If the obstacle only pushes the contact rod 12 to move a small distance (the contact rod 12 does not contact the magnet 19 on the linkage gear 15), the touch switch 13 will not be activated due to the light pushing force. The contact rod 12 will first retract into the bracket 1101 and then be driven back to its original position by the tension spring after passing the obstacle.

[0049] If an obstacle pushes the contact rod 12, causing it to contact the magnet 19 on the linkage gear 15, the touch switch 13 is activated, indicating that the obstacle needs to be avoided. After contacting the magnet 19 on the linkage gear 15, the contact rod 12 attracts to it. Driven by the obstacle, the contact rod 12 continues to move inward, causing the linkage rack 14 to move into the mounting bracket 11. The linkage rack 14 drives the linkage gear 15 to rotate, which in turn drives the transition gear 16 to rotate. The transition gear 16 then drives the limit gear 17 to rotate, which in turn drives the limit lever 18 to rotate. Rod 18 abuts against one side of support frame 7 and no longer jams support frame 7. Support frame 7 moves under the reset action of tension spring, causing drive gear 5 to disengage from slide rail rack 2. At the same time, touch switch 13 transmits a signal to winch 1, winch 1 starts, and quickly pulls moving frame 3 to one side of hull 26 (one winch 1 retracts the rope, the other winch 1 releases the rope). If touch switch 13 on one side is activated, moving frame 3 needs to move to the opposite side of hull 26. If touch switch 13 in the middle is activated, moving frame 3 can move in either direction.

[0050] When the movable frame 3 moves to the side of the hull 26, the push rod 20 passes through the movable frame 3 and moves the support frame 7, causing the support frame 7 to return to its original position. The limit lever 18 disengages from the side of the support frame 7, and the tension spring on the contact rod 12 begins to reset, causing the contact rod 12 and the linkage rack 14 to move outward. The linkage gear 15, the transition gear 16, and the limit gear 17 all rotate in the opposite direction. The limit lever 18 rotates in the opposite direction and locks the support frame 7 again. The drive gear 5 meshes with the slide rail rack 2 again. At this time, the magnets 19 on the contact rod 12 and the linkage rack 14 are still attracted together. While inspecting the sonar 10 that has moved to the side of the hull 26, the inspector pulls out the contact rod 12. Since the linkage rack 14 is blocked by the stop block 1103, the magnets 19 on the contact rod 12 and the linkage rack 14 can disengage from each other. The contact rod 12 returns to its original position under the reset action of the tension spring. After the inspector has checked the sonar 10 and found it to be correct, the movable frame 3 is moved to the working position again.

[0051] When the drive gear 5 meshes with the slide rail rack 2, and the moving frame 3 moves along the slide rail rack 2, the connecting plates 9 on both sides of the drive gear 5 alternately contact the protrusions 701 on their respective sides, causing the cutting blade 24 to reciprocate along the axis of the drive gear 5 in the blade groove 501, thereby cutting the debris (such as aquatic plants) in the slide rail rack 2 and cleaning the tooth gap of the slide rail rack 2.

[0052] When winch 1 retracts the wire rope, the wire rope is retrieved from the wire rope through hole 2101 of the cutter holder 21. The wire rope passes from bottom to top through the funnel formed by three cutting blades 24. The cutting blades 24 cut and clean debris (such as weeds) on the wire rope. If the debris on the wire rope is large, it may push the L-shaped rod 22 upward. The tension spring between the L-shaped rod 22 and the cutter holder 21 can pull the L-shaped rod 22 back to its original position, allowing the cutting blades 24 to continue cleaning the debris. When winch 1 releases the wire rope, the wire rope passes from top to bottom through the funnel formed by the three cutting blades 24. The L-shaped rod 22 may be driven to rotate downward. At this time, the limit block 23 can block the downward rotation of the L-shaped rod 22 to prevent it from affecting the movement of the wire rope.
