[0007] The limiting device includes four first rods, which are respectively fixedly connected to the top surface of the long rod, the top surface of the first rod is fixedly connected to an intermediate plate, the bottom of the intermediate plate is fixedly connected to a first rope, the top surface of the supporting shell is rotatably connected to four first rollers, the first ropes pass around the first rollers and the ends are fixedly connected to the limiting rod, the surface of the limiting rod is slidably connected to two fixing plates, the bottom of the fixing plate is fixedly connected to the top of the supporting shell, the surface of the limiting rod is fixedly connected to a first ring, the side surface of the first ring is fixedly connected to a second spring sleeved on the surface of the limiting rod, the other end of the second spring is fixedly connected to the side surface of the fixing plate, and the other end of the limiting rod is inserted into the side surface of the fixing pile;

[0008] The driving device includes two L-shaped receiving plates, which are fixedly connected to the bottom of the supporting shell. The top of the L-shaped receiving plate is slidably connected to a rack, which meshes with the teeth on the surface of the fixed pile. The top surface of the rack is fixedly connected to a transverse plate, and the side of the transverse plate is fixedly connected to a second rope. Both sides of the supporting shell are rotatably connected to the second roller, and both sides of the supporting shell are fixedly connected to a fixed long plate. The top of the fixed long plate is fixedly connected to the fixed shell, and the inner wall of the fixed shell is slidably connected to a buoyancy block. The second rope passes through the supporting shell, the fixed long plate, and passes around the second roller, and the end of the second rope is fixed to the bottom of the buoyancy block. The top inner wall of the fixed shell is slidably connected with a baffle plate, the baffle plate passes through the fixed shell and is fixedly connected to an L-shaped pulling plate at the end, the bottom of the baffle plate is fixedly connected to a reset plate, the side of the reset plate is fixedly connected to a reset spring, the other end of the reset spring is fixedly connected to the side of the fixed shell, the top of the fixed pile is fixedly connected to a bearing, the top of the bearing is fixedly connected to a frame rod, the side of the frame rod is fixedly connected to a triangular block, the inclined surface of the triangular block is adapted to the L-shaped pulling plate, the side of the frame rod is fixedly connected to an L-shaped limit plate that limits the rotation of the frame rod, and the side of the L-shaped limit plate is fixedly connected to a lower pressure plate;

[0009] During operation, in order to solve the problem that when the surveying instrument in the prior art is surveying the seabed, the mounting frame of the surveying instrument will be placed at a fixed position on the seabed as required. Due to the influence of undercurrents and seabed organisms on the seabed, the position of the surveying instrument will be offset, affecting the progress of the surveying work. The present technical solution solves the above problem by setting structures such as a support shell, a limit device and a drive device. When the entire equipment is placed on the seabed, the support plate will first contact the seabed, the support plate will be squeezed and drive the first rod to move upward through the long rod. At the same time, the long rod will squeeze the first spring through the fixed block, and the first rod will pull the first rope through the middle plate, and the first rope will synchronously pull the limit rod. The limit on the fixed pile is gradually released, and at the same time, the limit rod will drive the first ring to squeeze the second spring. The fixed pile with the limit released will gradually move downward under the action of its own heavier gravity. The fixed pile moving downward will drive the frame rod to move downward through the bearing, and the frame rod will drive the triangular block and the L-shaped limit plate to move downward. The L-shaped limit plate will drive the lower pressure plate to move downward. Since the bottom of the fixed pile is conical, the end of the fixed pile will drill into a part of the seabed. When the end of the fixed pile just contacts the mud and sand on the seabed, the triangular block will contact and squeeze the L-shaped pulling plate. The squeezed L-shaped pulling plate will move backward and drive the shielding plate to move. When the shielding plate just moves, seawater will pass through the shielding plate and the fixed shell The gap between the two ropes will enter the interior of the fixed shell. As seawater enters, the buoyancy block will float due to the buoyancy. As the fixed pile continues to move downward, the shielding plate will release the shielding on the inner wall of the fixed shell, and then the buoyancy block will move upward from the inside of the fixed shell under the action of buoyancy. At this time, the fixed pile will no longer move downward due to its own gravity. The upward moving buoyancy block will move by pulling the transverse plate through the second rope. The transverse plate drives the rack to move on the L-shaped receiving plate. The teeth on the rack and the top surface of the fixed pile are engaged, thereby driving the fixed pile to rotate. The bottom of the rotating fixed pile will have a digging effect on the mud and sand on the seabed. The fixed pile continues to move downward synchronously under its own gravity, so that the fixed pile penetrates into the seabed At a deeper position in the mud and sand, when the rack moves to the toothless part and contacts the fixed pile, the fixed pile will stop rotating. At this time, the bottom of the lower pressure plate will contact the top surface of the support shell, so that the downward pressure generated by the fixed pile is transmitted to the top of the support shell through the lower pressure plate, thereby playing a downward and fixed role on the entire device. Since the fixed pile is drilled into the seabed mud and sand to a certain depth, its lateral and longitudinal stability is guaranteed, avoiding the problem in the prior art that when the surveying instrument is conducting seabed surveying work, the mounting frame of the surveying instrument will be placed at a fixed position on the seabed as required. Due to the influence of undercurrents and seabed organisms on the seabed, the position of the surveying instrument will be offset, affecting the progress of the surveying and mapping work.

[0010] As a further solution of the present invention, the surface of the fixing pile is fixedly connected with a circular ring, the bottom of the circular ring is fixedly connected with a third spring sleeved on the surface of the fixing pile, the bottom of the third spring is fixedly connected with a connecting ring, the fixing pile passes through the connecting ring and is slidably connected to the connecting ring, the bottom of the connecting ring is fixedly connected with a plurality of plug-in plates distributed in a circular array, the bottom surface of the fixing pile is provided with an arc-shaped inclined surface, the bottom of the rack is fixedly connected with an extension rod, the bottom of the extension rod is fixedly connected with a special-shaped inclined plate, the special-shaped inclined plate and the connecting ring are adapted to the connecting ring, the bottom of the L-shaped receiving plate is provided with an open groove, the surface of the extension rod is slidably connected to the inner wall of the open groove; during operation, in order to further ensure that the fixing pile can be stably fixed on the seabed and thus fix the entire The function of the device is that this technical solution sets up structures such as a plug-in plate and a special-shaped inclined plate. When the rack moves to the toothless part and contacts the fixed pile, the fixed pile no longer rotates, and the rack will continue to move under the pull of the second rope. At the same time, the rack will drive the special-shaped inclined plate to move through the extension rod, and the special-shaped inclined plate will gradually move to contact the top surface of the connecting ring. The connecting ring will be subjected to the downward extrusion force of the special-shaped inclined plate, and the connecting ring will move downward while driving the plug-in plate to move. At the same time, the connecting ring will pull the third spring. Since the bottom surface of the fixed pile is provided with an arc-shaped inclined surface, the downward-moving plug-in plate will bend and move outward along the arc-shaped inclined surface, thereby causing the plug-in plate to be obliquely inserted downward into the mud and sand on the seabed, thereby further fixing the fixed pile, and thus fixing the entire device.

[0011] As a further solution of the present invention, the bottom surface of the plug board is inclined; during operation, in order to facilitate the plug board to move obliquely downward along the arc-shaped inclined surface, the inclined surface on the bottom surface of the plug board is provided so that it can easily move obliquely downward along the arc-shaped inclined surface.

[0012] As a further solution of the present invention, a long sliding groove is provided at the bottom of the L-shaped receiving plate, and a through rod is slidably connected to the inner wall of the long sliding groove, and the surface of the through rod is fixedly connected to the rack; during operation, in order to prevent the rack from deflecting when it moves on the L-shaped receiving plate, a through rod and other structures are provided so that the through rod is limited in the long sliding groove, and the through rod is fixedly connected to the rack, so that the rack cannot move left and right, thereby avoiding the problem of deflection when it moves on the L-shaped receiving plate.

[0013] As a further solution of the present invention, three extrusion springs are fixedly connected to the side of the L-shaped receiving plate, and the other end of the extrusion spring is fixedly connected to a sliding plate. The side of the sliding plate is slidably connected to the rack, and one end of the sliding plate is in contact with the inner wall of the support shell. During operation, in order to ensure that the teeth of the rack and the surface of the fixed pile are firmly engaged, structures such as extrusion springs and sliding plates are set, and extrusion force is applied to the sliding plate by the extrusion springs, and the sliding plate applies extrusion force to the rack, thereby increasing the extrusion force during engagement, ensuring that the teeth of the rack and the surface of the fixed pile are firmly engaged and will not loosen.

[0014] As a further solution of the present invention, a synchronization rod is fixedly connected to the surface of the support plate, and the other end of the synchronization rod is fixedly connected to the other support plates; during operation, in order to ensure that the limit rods on both sides of the fixed pile can simultaneously release the limit of the fixed pile when the limit is released, by setting structures such as synchronization rods, when the support plate drives the long rod to move upward, since the four support plates are connected together by the synchronization rod, when one, two or three of the support plates move upward, the rest will be driven to move upward together, thereby ensuring that the limit rods on both sides of the fixed pile can simultaneously release the limit of the fixed pile when the limit is released.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The present invention provides a support shell, a limit device, and a drive device. When the fixed pile is released from the limit, the fixed pile end is driven into a portion of the seabed by the heavy weight of the fixed pile itself and the conical surface at the bottom. The fixed pile is driven to rotate by the rack, so that the bottom of the fixed pile produces a digging effect on the seabed mud and sand. The fixed pile continues to move downward under its own weight, so that the fixed pile penetrates into a deeper position in the seabed mud and sand. When the fixed pile stops rotating, the bottom of the lower pressure plate contacts the top surface of the support shell, so that the downward pressure generated by the fixed pile is transmitted to the top of the support shell through the lower pressure plate, thereby exerting a downward pressure and fixing effect on the entire device. Since the fixed pile is drilled into the seabed mud and sand to a certain depth, its lateral and longitudinal stability is guaranteed. This avoids the problem in the prior art that when performing seabed mapping work, the surveying instrument mounting frame is placed at a fixed position on the seabed as required. Due to the influence of undercurrents and seabed organisms, the position of the surveying instrument will be offset, thereby affecting the progress of the mapping work.

[0017] 2. The present invention sets structures such as a plug-in plate and a special-shaped inclined plate. When the rack moves to the toothless part and contacts the fixed pile, the fixed pile stops rotating, and the rack will continue to move under the pull of the second rope. At the same time, the rack will drive the special-shaped inclined plate to move through the extension rod. The special-shaped inclined plate will gradually move to contact the top surface of the connecting ring. The connecting ring will be subjected to the downward extrusion force of the special-shaped inclined plate. The connecting ring will move downward and drive the plug-in plate to move at the same time. At the same time, the connecting ring will pull the third spring. Since the bottom surface of the fixed pile is provided with an arc-shaped inclined surface, the downward-moving plug-in plate will bend and move outward along the arc-shaped inclined surface, thereby causing the plug-in plate to be obliquely inserted downward into the mud and sand on the seabed, thereby further fixing the fixed pile and thus fixing the entire device.

[0018] 3. The present invention provides an inclined surface on the bottom surface of the plug board, so that the plug board can easily move obliquely downward along the arc-shaped inclined surface. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] The driving device includes two L-shaped receiving plates 20, which are fixedly connected to the bottom of the supporting shell 1. The top of the L-shaped receiving plate 20 is slidably connected to a rack 21, which meshes with the teeth 11 on the surface of the fixed pile 10. The top surface of the rack 21 is fixedly connected to a transverse plate 22, and the side of the transverse plate 22 is fixedly connected to a second rope 23. Both sides of the supporting shell 1 are rotatably connected to second rollers 24.

[0038] During operation, in order to solve the problem that the surveying instrument in the prior art will place the mounting frame of the surveying instrument at a fixed position on the seabed as required when surveying the seabed, and the position of the surveying instrument will be offset due to the influence of undercurrents and seabed organisms on the seabed, which affects the progress of the surveying work, the present technical solution solves the above problem by providing structures such as a support shell 1, a limit device and a drive device. When the entire device is placed on the seabed, the support plate 9 will first contact the seabed, the support plate 9 will be squeezed and drive the first rod 12 to move upward through the long rod 8, and at the same time the long rod 8 will squeeze the first spring 6 through the fixed block 7, and the first rod 12 will pull the first rope 14 through the middle plate 13, and the first rope 14 will synchronously pull the limit rod 16 The limit on the fixed pile 10 is gradually released, and at the same time, the limit rod 16 will drive the first ring 18 to squeeze the second spring 19. The fixed pile 10 with the limit released will gradually move downward under the action of its own heavier gravity. The downward-moving fixed pile 10 will drive the frame rod 33 to move downward through the bearing 32, and the frame rod 33 will drive the triangular block 34 and the L-shaped limit plate 35 to move downward. The L-shaped limit plate 35 will drive the lower pressure plate 36 to move downward. Since the bottom of the fixed pile 10 is conical, the end of the fixed pile 10 will drill into a part of the seabed. When the end of the fixed pile 10 just contacts the mud and sand on the seabed, the triangular block 34 will contact and squeeze the L-shaped pulling plate 29. The squeezed L-shaped pulling plate 29 will move backward and drive the shielding plate 28 to move. When the shielding plate 28 just moves, seawater will enter the interior of the fixed shell 26 through the gap between the shielding plate 28 and the fixed shell 26. As the seawater enters, the buoyancy block 27 will float due to the buoyancy. As the fixed pile 10 continues to move downward, the shielding plate 28 will release the shielding of the inner wall of the fixed shell 26, and then the buoyancy block 27 will move upward from the interior of the fixed shell 26 under the action of the buoyancy. At this time, the fixed pile 10 no longer moves downward due to its own gravity. The upward moving buoyancy block 27 will pull the transverse plate 22 to move through the second rope 23. The transverse plate 22 drives the rack 21 to move on the L-shaped receiving plate 20. The rack 21 engages with the teeth 11 on the top surface of the fixed pile 10, thereby driving the fixed pile 10 to rotate. The rotating fixed pile 10 The bottom will have a digging effect on the mud and sand on the seabed, and the fixed pile 10 will continue to move downward under its own gravity, so that the fixed pile 10 penetrates into a deeper position in the mud and sand on the seabed. When the rack 21 moves to the toothless part and contacts the fixed pile 10, the fixed pile 10 will stop rotating. At this time, the bottom of the lower pressure plate 36 will contact the top surface of the support shell 1, so that the downward pressure generated by the fixed pile 10 is transmitted to the top of the support shell 1 through the lower pressure plate 36, thereby playing a downward pressing and fixing role on the entire device. Since the fixed pile 10 is drilled into the mud and sand on the seabed to a certain depth, its lateral and longitudinal stability is guaranteed, which avoids the problem that the surveying instrument in the prior art will place the mounting frame of the surveying instrument at a fixed position on the seabed as required when conducting seabed surveying and mapping work.Due to the influence of undercurrents and seabed organisms on the seabed, the position of the surveying instrument will be offset, affecting the progress of surveying and mapping work.

[0039] As a further solution of the present invention, the surface of the fixing pile 10 is fixedly connected with a circular ring 37, and the bottom of the circular ring 37 is fixedly connected with a third spring 38 sleeved on the surface of the fixing pile 10, and the bottom of the third spring 38 is fixedly connected with a connecting ring 39. The fixing pile 10 passes through the connecting ring 39 and is slidably connected to the connecting ring 39. The bottom of the connecting ring 39 is fixedly connected with a plurality of plug-in plates 40 distributed in a circular array. The bottom surface of the fixing pile 10 is provided with an arc-shaped inclined surface 41, and the bottom of the rack 21 is fixedly connected with an extension rod 42, and the bottom of the extension rod 42 is fixedly connected with a special-shaped inclined plate 43. The special-shaped inclined plate 43 is adapted to the connecting ring 39. The bottom of the L-shaped receiving plate 20 is provided with an open groove 44, and the surface of the extension rod 42 is slidably connected to the inner wall of the open groove 44; during operation, in order to further ensure that the fixing pile 10 can be stably fixed on the seabed and thus play the role of fixing the entire device, the present technical solution The scheme is provided with structures such as the plug-in plate 40 and the special-shaped inclined plate 43. When the rack 21 moves to the toothless part and contacts the fixed pile 10, the fixed pile 10 no longer rotates, and the rack 21 will continue to move under the pull of the second rope 23. At the same time, the rack 21 will drive the special-shaped inclined plate 43 to move through the extension rod 42. The special-shaped inclined plate 43 will gradually move to contact the top surface of the connecting ring 39. The connecting ring 39 will be subjected to the downward squeezing force of the special-shaped inclined plate 43. The connecting ring 39 will move downward and drive the plug-in plate 40 to move. At the same time, the connecting ring 39 will pull the third spring 38. Since the bottom surface of the fixed pile 10 is provided with an arc-shaped inclined surface 41, the downward-moving plug-in plate 40 will bend outward along the arc-shaped inclined surface 41, thereby causing the plug-in plate 40 to be obliquely inserted downward into the mud and sand on the seabed, thereby further fixing the fixed pile 10 and thus fixing the entire device.

[0040] As a further solution of the present invention, the bottom surface of the plug board 40 is an inclined surface; during operation, in order to facilitate the plug board 40 to move obliquely downward along the arc-shaped inclined surface 41, an inclined surface is set on the bottom surface of the plug board 40 so that it can easily move obliquely downward along the arc-shaped inclined surface 41.

[0041] As a further solution of the present invention, a long slide groove 45 is provided at the bottom of the L-shaped receiving plate 20, and a through rod 46 is slidably connected to the inner wall of the long slide groove 45, and the surface of the through rod 46 is fixedly connected to the rack 21; during operation, in order to prevent the rack 21 from deflecting when moving on the L-shaped receiving plate 20, the through rod 46 and other structures are provided so that the through rod 46 is limited in the long slide groove 45, and the through rod 46 is fixedly connected to the rack 21, so that the rack 21 cannot move left and right, thereby avoiding the problem of its deflection when moving on the L-shaped receiving plate 20.

[0042] As a further solution of the present invention, three extrusion springs 47 are fixedly connected to the side of the L-shaped receiving plate 20, and the other end of the extrusion spring 47 is fixedly connected to a sliding plate 48. The side of the sliding plate 48 is slidably connected to the rack 21, and one end of the sliding plate 48 is in contact with the inner wall of the support shell 1; during operation, in order to ensure that the rack 21 and the teeth 11 on the surface of the fixed pile 10 are firmly engaged, by providing structures such as extrusion springs 47 and sliding plates 48, the extrusion springs 47 apply extrusion force to the sliding plate 48, and the sliding plate 48 applies extrusion force to the rack 21, thereby increasing the extrusion force during engagement, ensuring that the rack 21 and the teeth 11 on the surface of the fixed pile 10 are firmly engaged and will not loosen.

[0043] As a further solution of the present invention, a synchronization rod 49 is fixedly connected to the surface of the support plate 9, and the other end of the synchronization rod 49 is fixedly connected to the other support plates 9; during operation, in order to ensure that the limit rods 16 on both sides of the fixed pile 10 can simultaneously release the limit of the fixed pile 10 when the limit is released, by setting structures such as the synchronization rod 49, when the support plate 9 drives the long rod 8 to move upward, since the four support plates 9 are connected together by the synchronization rod 49, when one, two or three support plates 9 move upward, the rest will be driven to move upward together, thereby ensuring that the limit rods 16 on both sides of the fixed pile 10 can simultaneously release the limit of the fixed pile 10 when the limit is released.

[0044] Working principle: When the entire equipment is placed on the seabed, the support plate 9 will first contact the seabed, the support plate 9 will be squeezed and drive the first rod 12 to move upward through the long rod 8, and at the same time the long rod 8 will squeeze the first spring 6 through the fixed block 7, the first rod 12 will pull the first rope 14 through the middle plate 13, the first rope 14 will synchronously pull the limit rod 16 to gradually release the limit on the fixed pile 10, and at the same time the limit rod 16 will drive the first ring 18 to squeeze the second spring 19, the fixed pile 10 that has been released from the limit will gradually move downward under the action of its own heavier gravity, the downward moving fixed pile 10 will drive the frame rod 33 to move downward through the bearing 32, and the frame rod 33 drives the three The corner block 34 and the L-shaped stop plate 35 move downward, and the L-shaped stop plate 35 will drive the lower pressure plate 36 to move downward. Since the bottom of the fixed pile 10 is conical, the end of the fixed pile 10 will drill into a part of the seabed. When the end of the fixed pile 10 just contacts the mud and sand on the seabed, the triangular block 34 will contact and squeeze the L-shaped pulling plate 29. The squeezed L-shaped pulling plate 29 will move backward and drive the shielding plate 28 to move. When the shielding plate 28 just moves, seawater will enter the interior of the fixed shell 26 through the gap between the shielding plate 28 and the fixed shell 26. As seawater enters, the buoyancy block 27 will float under the buoyancy force. As the fixed pile 10 continues to move downward, the shielding plate 28 will be released. The inner wall of the fixed shell 26 is blocked, and then the buoyancy block 27 will move upward from the inside of the fixed shell 26 under the action of buoyancy. At this time, the fixed pile 10 no longer moves downward due to its own gravity. The upward moving buoyancy block 27 will pull the transverse plate 22 to move through the second rope 23. The transverse plate 22 drives the rack 21 to move on the L-shaped receiving plate 20. The rack 21 is engaged with the teeth 11 on the top surface of the fixed pile 10, thereby driving the fixed pile 10 to rotate. The bottom of the rotating fixed pile 10 will produce a digging effect on the mud and sand on the seabed. The fixed pile 10 continues to move downward synchronously under its own gravity, so that the fixed pile 10 goes deep into a deeper position in the mud and sand on the seabed. When the toothless part contacts the fixed pile 10, the fixed pile 10 will stop rotating. At this time, the bottom of the lower pressure plate 36 will contact the top surface of the support shell 1, so that the downward pressure generated by the fixed pile 10 is transmitted to the top of the support shell 1 through the lower pressure plate 36, thereby playing a downward and fixed role on the entire device. Since the fixed pile 10 is drilled into the seabed mud to a certain depth, its lateral and longitudinal stability is guaranteed, avoiding the problem in the prior art that when the surveying instrument in the seabed is surveying and mapping, the mounting frame of the surveying instrument will be placed in a fixed position on the seabed as required. Due to the influence of undercurrents and seabed organisms on the seabed, the position of the surveying instrument will be offset, affecting the progress of the surveying and mapping work.
