[0002] The depth sounder is a new generation of fully digital and computerized products. It is dustproof, waterproof and shockproof. It is a measurement device that integrates water depth measurement, software graphic navigation, positioning data and water depth data acquisition functions. It is an ideal device for depth measurement of oceans, rivers, lakes and land, as well as for surveying in mining, port and waterway dredging projects. When in use, the ocean depth sounder is deployed into the ocean through a launch and take-off device to take measurements.

[0015] The present invention also provides a method for launching and recovering a marine depth sounder, comprising the following steps:

[0016] Step 1: Start the drive motor to make the winding wheel on the drive shaft rotate, so that the rope on the winding wheel can be placed in the sea to measure the depth. The rope can be directly controlled by the motor to raise and lower.

[0017] Step 2: When the rope comes into contact with the pulley in the swing direction, the azimuth shaft on the pulley moves within the straight groove on the linkage plate, causing the two positioning clamps to drive the two stabilizing blocks to move towards each other within the limiting rod on the stabilizing box, thereby reducing the impact of seawater surging on the rope.

[0018] Step 3: The pulley-assisted rotating shaft drives the driven bevel gear to rotate, which causes the deflector rod on the drive plate to drive the rectangular block to move back and forth on the brake base. This causes the two cleaning bend plates to move back and forth, which can clean the marine debris or impurities attached to the rope.

[0019] Step 4: When the rope is pulled, it moves within the brake rod on the brake groove by the brake block on the pressure clamp plate. The brake spring and support spring are in a buffer state. When the garbage or impurities attached to the rope reach their maximum mass, the moving contact plate on the pressure clamp plate contacts the stationary contact plate on the support plate, causing the pressure alarm to start working. The pressure alarm shuts down the drive motor by sending an interrupt signal and sounds an alarm to remind the operator.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] (1) After the mounting plate of the device is installed in the required position, the drive motor is started. The drive pulley on the output end of the drive motor drives the winding pulley to rotate through the conveyor belt, which in turn causes the winding wheel on the drive shaft to rotate. This allows the rope on the winding wheel to place the depth sounder in the sea for depth measurement. The rope can be directly controlled by the motor, avoiding manual operation, saving time and effort, and thus improving the efficiency of measurement.

[0022] (2) Because there is too much marine debris or impurities in the seawater, they are easy to attach to the rope as it rises, which increases the force required for tension. When the rope is pulled, the brake block on the pressure plate moves in a limited position within the brake rod in the brake groove, and the brake spring is in a buffer state. At the same time, the support rod moves in a limited position within the support groove, and the support spring is in a compressed state. When the debris or impurities attached to the rope reach the maximum mass, the moving contact plate on the pressure plate contacts the stationary contact plate on the support plate, thereby triggering the pressure alarm. The pressure alarm shuts off the drive motor by sending an interrupt signal, so that the drive motor no longer drives the rope to rise, and at the same time, it sounds an alarm to remind the operator. This can effectively protect the rope and the device.

[0023] (3) The two positioning clamps drive the two driving blocks to move towards each other within the limit rods on the stabilizing box. The two limit springs are in a stretched state and the compression spring is in a compressed state, thereby reducing the impact of seawater surging on the rope and preventing the rope from damaging other parts when it surges with the seawater. When the seawater stops surging, the rope no longer contacts the pulley, causing the limit spring and compression spring to reset and the pulley to return to its original position. By setting four pulleys around the rope, the impact of seawater on the device can be effectively reduced, thus protecting the depth sounder.

[0024] (4) When the device is not needed or the depth sounder has been placed in the ocean for operation, by installing the locking double plate inward, the winding wheel is stopped from rotating. Then, the handle is released and the limiting spring is reset, so that the positioning rod on the positioning block limits the locking double plate, preventing the locking double plate from moving outward and avoiding rotation due to non-human factors. At the same time, by releasing the locking rod, the locking spring is reset, so that the locking rod is reset to limit the handle again, thus limiting the positioning block and preventing the positioning rod from dislodging due to shaking of the positioning block.

[0025] (5) Rotate the rocking plate so that the tight plate on the drive threaded rod moves to the upper limit of the guide rod. The guide spring is in a buffer state, which in turn causes the auxiliary plate on the tight plate to drive the azimuth drive unit to move. The contact distance between the four pulleys on the azimuth drive unit and the rope can be adjusted so that the azimuth drive unit can accept ropes of different diameters, reducing the limitations of use.

[0026] (6) When the seawater stops surging, the rope is reset, and the locking cross block rotates at the upper limit of the bending rod through the control lever. The bending spring is in a buffer state, which causes the two locking rods to move towards each other and connect with the locking groove on the drive cross block, thereby limiting the pulley on the drive cross block and preventing the pulley from dislodging due to the impact caused by the sudden reset of the limit spring and compression spring on the azimuth drive stabilization unit caused by the sudden calming of the seawater.

[0027] (7) When moving towards each other, the reset rod on the reset plate moves on the reset plate, and the reset spring is in a buffer state. When resetting, the relative movement causes the reset spring to reset, so that the two reset plates can clean the marine debris or impurities attached to the rope. This effectively avoids the impurities attached to the rope when the rope is being wound up, and improves the winding efficiency of the cable. At the same time, when the seawater surge causes the rope to no longer contact this pulley, other pulleys that are in contact can be equipped with reset cleaning units. The reset plates on the four reset cleaning units (not shown in the figure, only one reset cleaning unit is described) are set at different heights to avoid collisions. This allows any reset plate to continuously clean the rope. The reset rod and reset spring can provide a good buffer effect when encountering large impurities or debris, and prevent the reset plates from failing to reset, which would result in poor cleaning effect.

[0041] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0042] Implementation examples, by Figures 1 to 10The present invention includes a mounting plate 1, on which a support plate 2 is symmetrically fixedly mounted. A drive motor 3 is fixedly mounted on the support plate 2, and the drive motor 3 is connected to a retraction control assembly. The retraction control assembly includes a drive pulley 4 disposed on the output end of the drive motor 3. The drive pulley 4 is connected to a retraction pulley 6 via a conveyor belt 5. A drive shaft 7 is mounted on the retraction pulley 6. The drive shaft 7 passes through a bearing provided on the support plate 2 and is fixedly connected to a connecting block 8. The connecting block 8 is connected to a fixed-axis locking mechanism. A winding wheel 9 is mounted on the drive shaft 7. A rope 10 is provided on the winding wheel 9. The rope 10 is connected to a depth sounder 13 via a positioning wheel 11 and several pulleys 12 that are connected in cooperation. The positioning wheel 11 is connected to a pressure-stopping component. The pulleys 12 are connected to an azimuth stabilization unit.

[0043] After the operator installs the mounting plate 1 of the device in the required position, the operator starts the drive motor 3. The drive pulley 4 on the output end of the drive motor 3 drives the winding pulley 6 to rotate through the conveyor belt 5, which in turn causes the winding wheel 9 on the drive shaft 7 to rotate. This allows the rope 10 on the winding wheel 9 to place the depth sounder 13 in the sea for depth measurement. The rope is directly controlled by the motor, avoiding manual operation, saving time and effort, and thus improving the efficiency of measurement.

[0044] The azimuth drive and stabilization unit of this embodiment includes an azimuth rotating shaft 14 disposed on both sides of the pulley 12. The azimuth rotating shaft 14 passes through a straight slot on the linkage plate 15 and is connected to the drive horizontal block 16. A positioning clamp rod 17 is installed on the linkage plate 15 and is connected to the tight-position drive mechanism. An auxiliary rotating shaft 18 connected to the azimuth rotating shaft 14 is installed on one of the drive horizontal blocks 16. A driving bevel gear 19 is installed on the auxiliary rotating shaft 18. The driving bevel gear 19 meshes with a driven bevel gear 20. The driven bevel gear 20 is connected to the re-movement clearing unit. Connecting blocks 21 are symmetrically installed on the two drive horizontal blocks 16. A drive rod 22 is movably installed on the connecting block 21. A drive stabilizing block 23 is movably mounted on the drive rod 22. The drive stabilizing block 23 is slidably connected to the transverse groove 25 provided on the stabilizing box 24. The two stabilizing boxes 24 are fixedly connected to the side of the linkage plate 15. A control rotating rod 26 is drivenly mounted on one end of the drive rod 22 near the stabilizing box 24. The control rotating rod 26 is connected to the locking and releasing mechanism. A limit rod 27 is fixedly mounted on the transverse groove 25. A limit spring 28 is sleeved on the limit rod 27. One end of the limit spring 28 is fixedly connected to the transverse groove 25, and the other end is fixedly connected to the drive stabilizing block 23. The two drive stabilizing blocks 23 are connected by a compression spring 29, which is sleeved on the limit rod 27.

[0045] After the measurement is completed, the operator uses the drive motor 3 to retrieve the rope 10 carrying the depth sounder 13. This causes a pulley 12 in contact with the rope 10 to rotate. When the seawater surges, the rope 10 swings in the direction of the surge, causing it to contact the pulley 12 in the swing direction. This causes the azimuth shaft 14 on the pulley 12 to move within the straight groove on the linkage plate 15, which in turn moves the drive block 16. This causes the two positioning clamps 17 to move the two stabilizing blocks 23 towards each other within the limiting rods 27 on the stabilizing box 24. When the rope 10 is in motion, the two limiting springs 28 are in a stretched state and the compression spring 29 is in a compressed state, thereby reducing the impact force of the seawater surge on the rope 10 and preventing the rope 10 from damaging other parts when it is in motion with the seawater. When the seawater stops surging, the rope 10 no longer contacts the pulley 12, causing the limiting springs 28 and the compression spring 29 to reset, and the pulley 12 to return to its original position. By setting four pulleys 12 around the rope 10, the impact force of the seawater on the device can be effectively reduced, thus protecting the depth sounder 13.

[0046] The pressure-activated stop assembly of this embodiment includes a pressure clamping plate 30 driven on a positioning wheel 11. Brake blocks 31 are installed on both sides of the pressure clamping plate 30. The brake blocks 31 are slidably connected to the brake grooves 32 provided on the mounting plate 1. A brake rod 33 is fixedly installed on the brake grooves 32. A brake spring 34 is sleeved on the brake rod 33. One end of the brake spring 34 is fixedly connected to the brake grooves 32, and the other end is fixedly connected to the brake blocks 31. Support rods 35 are symmetrically installed on the pressure clamping plate 30. The support rods 35 are slidably connected to the support grooves 36 provided on the support plate 2. A support spring 37 is sleeved on the support rods 35. One end of the support spring 37 is fixedly connected to the support plate 2, and the other end is fixedly connected to the pressure clamping plate 30. A movable contact piece 38 is installed on the protrusion on the pressure clamping plate 30. The movable contact piece 38 is connected to a stationary contact piece 39 provided in the groove on the support plate 2. The contact between the stationary contact piece 39 and the movable contact piece 38 is used to control the driving stationary state of the pressure alarm.

[0047] When the rope 10 is pulling the depth sounder 13 upward, due to the excessive marine debris or impurities in the seawater, these easily adhere to the rope 10 as it rises, increasing the force required for tension. This causes the rope 10 to be limited in movement by the brake block 31 on the pressure clamp 30 within the brake rod 33 on the brake groove 32, with the brake spring 34 in a buffered state. Simultaneously, the support rod 3 is limited in movement within the support groove 36, and the support spring 37 is compressed. When the debris or impurities attached to the rope 10 reach their maximum mass, the moving contact 38 on the pressure clamp 30 contacts the stationary contact 39 on the support plate 2, triggering the pressure alarm. The pressure alarm sends an interrupt signal to shut off the drive motor 3, preventing it from driving the rope 10 upward, and simultaneously emits an alarm sound to alert the operator. This effectively protects the rope 10 and the device.

[0048] The locking and unlocking mechanism of this embodiment includes a locking horizontal block 40 connected to the control lever 26. A locking rod 41 is fixedly installed on the locking horizontal block 40, and the locking rod 41 is connected to the locking groove 42 provided on the drive horizontal block 16. A bending rod 43 is installed on the locking horizontal block 40. The bending rod 43 passes through the drive base 44 and is connected to the first limiting plate. The drive base 44 is fixedly connected to the drive stabilizing block 23. A bending spring 45 is sleeved on the bending rod 43. One end of the bending spring 45 is fixedly connected to the drive base 44, and the other end is fixedly connected to the locking horizontal block 40.

[0049] When the seawater stops surging, the rope 10 resets, causing the locking block 40 to rotate at the upper limit of the bending rod 43 via the control lever 26. The bending spring 45 is in a buffer state, which in turn causes the two locking rods 41 to move towards each other and connect with the locking groove 42 on the drive block 16, thereby limiting the pulley 12 on the drive block 16. This prevents the pulley 12 from dislodging due to the impact caused by the sudden reset of the limiting spring 28 and the compression spring 29 on the azimuth stabilization unit caused by the sudden calming of the seawater.

[0050] The re-motion clearing unit of this embodiment includes a driven shaft 46 disposed on a driven bevel gear 20. The driven shaft 46 passes through a driven base 47 disposed on a drive block 16 and is connected to a drive circular plate 48. A decelerating rod 49 is mounted on the drive circular plate 48. The decelerating rod 49 is slidably connected to a rectangular groove 51 provided on a rectangular block 50. The rectangular block 50 passes through a brake base 52 disposed on the drive block 16 and is connected to a drive rack 53. A first slider 54 is mounted on the drive rack 53. The first slider 54 is slidably connected to a first slide box 55. The two first slide boxes 55 are connected to a control base 56. The control base 56 is fixedly connected to the brake base 52. The drive rack 53 meshes with a drive gear 57. A decelerating shaft 58 is mounted on the drive gear 57. One end of 58 is connected to the control base 56 for transmission, and the other end is connected to the driven gear 59. The driven gear 59 meshes with two moving racks 60. A second slider 61 is mounted on the moving rack 60. The second slider 61 is slidably connected to the second slide box 62. The two second slide boxes 62 are fixedly connected to the first slide box 55. A special-shaped rod 80 is mounted on the moving rack 60. The special-shaped rod 80 is fixedly connected to the reset plate 81. A reset rod 82 is mounted on the reset plate 81. One end of the reset rod 82 is fixedly connected to the third limit plate, and the other end is fixedly connected to the cleaning bending plate 83. The two cleaning bending plates 83 are connected to the rope 10. A reset spring 84 is sleeved on the reset rod 82. One end of the reset spring 84 is fixedly connected to the reset plate 81, and the other end is fixedly connected to the cleaning bending plate 83.

[0051] The pulley 12 near the positioning wheel 11 is in constant contact with the rope 10. When the rope drives the depth sounder 13 upward, the auxiliary shaft 18 on the contacting pulley 12 drives the driven bevel gear 20 to rotate. This causes the decelerating rod 49 on the drive plate 48 to drive the rectangular block 50 to reciprocate on the brake base 52. Consequently, the driving gear 57 meshing with the drive rack 53 reciprocates, causing the driven gear 59 on the decelerating shaft 58 to mesh with two moving racks 60. This causes the irregular rods 80 on the two moving racks 60 to drive the reset plate 81 to reciprocate, moving in a state of first facing each other and then relative to each other. When moving in opposite directions, the reset rod 82 on the clearing bending plate 83 moves on the reset plate 81, and the reset spring 84 is in a buffered state. During the reset, the relative movement causes the reset plate to reciprocate. The spring 84 resets, allowing the two cleaning bends 83 to clean marine debris or impurities attached to the rope 10. This effectively prevents the rope 10 from winding up with impurities during ascent, improving the winding efficiency. Simultaneously, when the surging seawater causes the rope 10 to lose contact with a pulley, other pulleys can be equipped with reactivation cleaning units. The cleaning bends 83 on the four reactivation cleaning units (not shown in the figure, only one is described) are positioned at different heights to avoid collisions, ensuring that any cleaning bend 83 can continuously clean the rope 10. The reset rod 82 and reset spring 84 provide a good buffer when encountering large impurities or debris, preventing poor cleaning performance due to the cleaning bends 83 not resetting.

[0052] The locking mechanism of this embodiment includes a connecting groove 63 connected to the connecting block 8. The connecting groove 63 is disposed on the locking disc 64. A locking double plate 65 is installed on the locking disc 64. One side of the locking double plate 65 is connected to a handle 66, and the other end is connected to a positioning box 67. The positioning box 67 is disposed in a locking groove 68, which is symmetrically arranged on the support plate 2. The locking double plate 65 is symmetrically provided with positioning grooves 69. Positioning rods 70 are installed on the positioning grooves 69. The positioning rods 70 are fixedly connected to the positioning block 71, and the positioning block 71 is slidably connected to the locking groove 68. The locking groove 68 is symmetrically provided with positioning grooves 69. The device is equipped with a limiting groove 72, on which a limiting rod 73 is installed. A limiting spring 74 is sleeved on the limiting rod 73. One end of the limiting spring 74 is fixedly connected to the limiting groove 72, and the other end is fixedly connected to a limiting block 75. Two limiting blocks 75 are fixedly connected to a positioning block 71. A handle 76 is installed on the positioning block 71, and a locking rod 77 is installed on the handle 76. The locking rod 77 passes through a locking base 78 set on the support plate 2 and is connected to a second limiting plate. A locking spring 79 is sleeved on the locking rod 77. One end of the locking spring 79 is connected to the second limiting plate, and the other end is fixedly connected to the locking base 78.

[0053] When the winding wheel 9 needs to rotate, pulling the locking rod 77 upwards causes the locking spring 79 to be in a buffered state, releasing the locking rod 77 from its limiting setting on the handle 76, allowing it to move. Pulling the handle 76 to the side causes the limiting block 75 on the positioning block 71 to move at its upper limit on the limiting rod 73. The limiting spring 74 is in a buffered state, preventing the positioning rod 70 on the positioning block 71 from releasing the positioning box 67 and the locking double plate 65. Pulling the locking double plate 65 outwards releases the limiting setting on the locking disc 64, allowing the winding wheel 9 to rotate normally. When the device is needed or the depth sounder 13 is already in the ocean for operation, by installing the locking double plate 65 inward, the winding wheel 9 is stopped from rotating. Then, the handle 76 is released, the limiting spring 74 is reset, and the positioning rod 70 on the positioning block 71 is set to limit the locking double plate 65, so that the locking double plate 65 cannot move outward, avoiding rotation due to non-human factors. At the same time, by releasing the locking rod 77, the locking spring 79 is reset, so that the locking rod 77 is set to limit the handle 76 again, and the positioning block 71 is limited, preventing the positioning block 71 from shaking and causing the positioning rod 70 to dislodge.

[0054] The clamping drive mechanism of this embodiment includes an auxiliary plate 85 connected to several positioning clamping rods 17. A clamping plate 86 is installed on the auxiliary plate 85. The clamping plate 86 is threadedly connected to a drive threaded rod 87. One end of the drive threaded rod 87 is connected to a fourth limiting plate, and the other end passes through an auxiliary base 88 set on the mounting plate 1 and is connected to a rocking rotating plate 89. A guide rod 90 is installed on the auxiliary base 88. One end of the guide rod 90 is connected to a fifth limiting plate, and the other end is fixedly connected to the auxiliary plate 85. A guide spring 91 is sleeved on the guide rod 90. One end of the guide spring 91 is fixedly connected to the auxiliary plate 85, and the other end is fixedly connected to the auxiliary base 88.

[0055] By rotating the rocker plate 89, the clamping plate 86 on the drive threaded rod 87 moves to the upper limit of the guide rod 90, and the guide spring 91 is in a buffer state. Then, the auxiliary plate 85 on the clamping plate 86 drives the azimuth drive and stabilization unit to move. The contact distance between the four pulleys 12 on the azimuth drive and stabilization unit and the rope 10 can be adjusted, so that the azimuth drive and stabilization unit can accept ropes of different diameters, reducing the limitations of use.

[0056] The present invention also provides a method for launching and recovering a marine depth sounder, comprising the following steps:

[0057] Step 1: Start the drive motor 3 to make the winding wheel 9 on the drive shaft 7 rotate, so that the rope 10 on the winding wheel 9 can place the depth sounder 13 in the sea to measure the depth. The rope can be directly controlled by the motor to release and retract.

[0058] Step 2: When the rope 10 contacts the pulley 12 in the swing direction, the azimuth shaft 14 on the pulley 12 moves within the straight groove on the linkage plate 15, causing the two positioning clamps 17 to drive the two stabilizing blocks 23 to move towards each other within the limiting rod 27 on the stabilizing box 24, thereby reducing the impact of seawater surging on the rope 10.

[0059] Step 3: The pulley 12 and the auxiliary shaft 18 drive the driven bevel gear 20 to rotate, which causes the derailment rod 49 on the drive plate 48 to drive the rectangular block 50 to reciprocate on the brake base 52, so that the two cleaning bending plates 83 reciprocate to clean the marine debris or impurities attached to the rope 10.

[0060] Step 4: When the rope 10 is pulled, it moves within the brake rod 33 on the brake groove 32 by the brake block 31 on the pressure clamp 30. The brake spring 34 and the support spring 37 are in a buffer state. When the garbage or impurities attached to the rope 10 reach the maximum mass, the moving contact piece 38 on the pressure clamp 30 contacts the stationary contact piece 39 on the support plate 2, causing the pressure alarm to start working. The pressure alarm shuts off the drive motor 3 by sending an interrupt signal and sounds an alarm to remind the operator.
