Description

Technical Field

[0001] The present invention relates to the technical field of marine surveying and mapping, and specifically to a marine surveying and mapping positioning device. Background Art

[0002] Marine surveying and mapping includes multiple aspects such as offshore positioning, marine geodetic surveying, underwater topographic surveying, etc.; marine surveying and mapping positioning devices provide basic data support for these surveying tasks by providing accurate position information. For example, when mapping the seabed topographic map, it is necessary to accurately know the position of the measurement point to ensure the accuracy of the topographic map.

[0003] As disclosed in the patent with publication number CN221811582U, a positioning device for a marine surveying instrument is proposed. It includes a counterweight frame with multiple counterweight slots, counterweight blocks slidably arranged in the counterweight slots, and two groups of fixed ejection mechanisms symmetrically arranged in the counterweight slots; a fixed disk arranged on the counterweight frame; and a mounting block arranged on the fixed disk with multiple mounting holes for mounting marine surveying instruments. By setting the fixed ejection mechanism, before the entire positioning device sinks underwater, the required number of counterweight blocks are inserted into the counterweight slots. When inserting, the fixed block rotates, compressing the ejection spring, and after releasing the hand, the ejection spring elongates and the fixed block rotates in the reverse direction and inserts into the fixed slot. When the positioning device sinks underwater, the counterweight blocks are prevented from separating from the device.

[0004] Currently, during the process of sea area surveying and mapping, whether the instrument observes perpendicular to the seabed directly affects the data quality. If the position cannot be maintained within the predetermined range, there will be a deviation between the surveyed data and the actual data. Moreover, the device is positioned relying on counterweight blocks, and there are many uncertain factors on the seabed, such as being affected by fish schools, which may cause the device to move, having an impact; in addition, during the process of the device diving, if it passes through an area with seaweed, there may be a situation where floating seaweed entangles the spiral blades. If the spiral blades are entangled, on the one hand, it cannot dive to the designated range, and on the other hand, it is not convenient for the device to be recovered; furthermore, during the diving process of the spiral blades, due to external factors such as being impacted by fish schools and entangled by seaweed, the spiral blades may bend. The bent spiral blades will affect the diving direction and affect the surveying and mapping.

[0005] In view of the above problems, a marine surveying and mapping positioning device is proposed. Summary of the Invention

[0010] Each first electric push rod is rotatably connected to one side of the bottom end of the adjacent second slider, an installation ring is fixedly connected to the top end of the rotating rod, a plurality of stoppers are fixedly connected to the side wall of the installation ring at equal angles, and the stopper and the adjacent second wedge block are located in the same vertical plane;

[0011] The repair component includes a plurality of second electric push rods, each second electric push rod is fixedly connected to the side wall of the rotating rod, and a repair ring is slidably connected to the side wall of each spiral blade;

[0012] A connecting plate is fixedly connected to the side wall of the repair ring, and the movable end of each second electric push rod is fixedly connected to the side wall of the adjacent connecting plate.

[0014] Further, a plurality of first sliders are symmetrically and slidably connected to the bottom wall inside the second cavity. A second spring is symmetrically and fixedly connected to the side wall of each first slider, and each second spring is fixedly connected to the inner side wall of the second cavity. A limiting plate is fixedly connected to the side wall of the first slider, and one end of the limiting plate is hermetically and slidably connected through the inner side wall of the second cavity.

[0015] Further, a first wedge-shaped block is fixedly connected to the top wall of one end of the limiting plate. Support plates are symmetrically and fixedly connected to the side wall of the load-bearing block.

[0016] Further, a third spring is fixedly connected to the bottom wall of the mounting plate, and one end of the third spring is fixedly connected to the top wall of the support plate. A limiting hole is provided in the side wall of each positioning plate, and a wedge-shaped groove is provided in the top wall of the limiting hole. The first wedge-shaped block is in sliding contact with the wedge-shaped groove.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] By setting the positioning component, when the motor works, it drives the rotating rod and the spiral blade to rotate. Using the thrust generated by the rotation of the spiral blade, the device is driven to move towards the seabed. By the spiral blade pushing the device downward, it dives vertically to a great extent, avoiding the displacement of the surveying device under the action of seawater flow and even deviating from the survey area, ensuring that the device can be accurately placed within the survey range and improving the practicability of the device; through the crushing component, when the first electric push rod is started, the first electric push rod starts to extend. The blade is driven to move upward along the chute through the connecting block. When the blade moves to the upper limit position of the chute, the second wedge-shaped block contacts the bottom end of the stopper, and the first electric push rod is rotatably connected to one side of the bottom end of the connecting block. Therefore, during the upward movement of the first electric push rod, it will drive the connecting block, the rotating shaft and the blade to rotate until the inclined piece of the second wedge-shaped block abuts against the bottom end of the stopper, making the blade in an inclined state. Using the blade in an inclined state, it rotates synchronously with the rotating rod to vertically cut the surrounding seaweed, avoiding the direct cutting of the seaweed close to the spiral blade and further preventing the seaweed from winding around the spiral blade, ensuring that the device can smoothly dive to the designated survey range for surveying and improving the use effect of the device;

[0019] By setting up a repair component, when the spiral blade is bent and deformed, the second electric push rod is activated. The movable end of the second electric push rod starts to extend, driving the repair ring through the connecting plate to synchronously extend along the surface of the spiral blade. Since the repair ring slides against the side wall of the spiral blade, during the movement along the spiral blade, it will come into contact with the bent and deformed position and repair it. As the repair ring moves to the end of the spiral blade, the second electric push rod starts to contract, driving the repair ring to contract and reset. During this process, the bent and deformed position can be repaired again, avoiding affecting the diving direction due to the bending of the spiral blade, ensuring the shape of the spiral blade, so that it can dive to the specified survey range for surveying, improving the practicality of the device.

Detailed implementation manners

[0033] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to 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. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0034] In order to solve the technical problems that during the sea area surveying and mapping process, whether the instrument is vertically observed on the seabed directly affects the data quality. If the position cannot be kept within a predetermined range, there will be a deviation between the surveyed data and the actual data, and the device is positioned close to the load block 3, and there are many uncertain factors on the seabed, such as being affected by fish schools, resulting in the device moving, which has an impact, as Figure 1 - Figure 7 shown, the following preferred technical solutions are provided:

[0035] An ocean survey and positioning device includes a bearing plate 1. A waterproof cover 2 is installed at the top of the bearing plate 1. An ocean survey device is installed inside the waterproof cover 2. The ocean survey device belongs to the prior art and is the main instrument required for ocean survey. Symmetrically and fixedly connected to the bottom of the bearing plate 1 are airbags 11. Since it operates in deep sea, the material of the airbags 11 has sufficient pressure resistance. And an air inflation pump and an air storage cavity are provided on the bearing plate 1. The airbags 11 are in an initial state without gas inside. When the device needs to be recovered, the air inflation pump is used to pump the gas in the air storage cavity into the airbags 11, causing the airbags 11 to expand. Thus, the buoyancy of the device is greater than the gravity of the device, and then it starts to float until the sea surface. Symmetrically and fixedly connected to the bottom end of the bearing plate 1 are cable ropes 12. The two groups of cable ropes 12 are jointly and fixedly connected to a weight 3. Sufficient gravity is generated by the weight 3 to overcome the buoyancy of the sea water and make the device sink to the seabed position where ocean survey needs to be carried out. A first cavity 31 is opened on the inner wall of the weight 3. A motor 32 is fixedly connected to the inner wall of the first cavity 31. The output end of the motor 32 is fixedly connected to a rotating rod 33. One end of the rotating rod 33 penetrates through the top wall and the rear side wall of the first cavity 31 and is fixedly connected with a plurality of spiral blades 34 at equal angles. A second cavity 35 is opened on the inner wall of the weight 3. A positioning component 4 is installed inside the second cavity 35. By setting the positioning component 4, when the motor 32 works, it drives the rotating rod 33 and the spiral blades 34 to rotate. Using the thrust generated by the rotation of the spiral blades 34, the device is driven to move towards the seabed. By the spiral blades 34 pushing the device downward, the device dives vertically to a great extent, avoiding the displacement of the survey device under the action of sea water flow and even deviating from the survey area, ensuring that the device can be accurately placed within the survey range and improving the practicability of the device.

[0036] A crushing component 5 is installed on the side wall of the rotating rod 33. Through the crushing component 5, when the first electric push rod 57 is started, the first electric push rod 57 starts to extend. The blade 56 is driven to move upward along the sliding groove 51 through the connecting block 55. When the blade 56 moves to the upper limit position of the sliding groove 51, the second wedge-shaped block 511 contacts the bottom end of the stopper 59. And the first electric push rod 57 is rotatably connected to one side of the bottom end of the connecting block 55. Thus, during the upward movement of the first electric push rod 57, it will drive the connecting block 55, the rotating shaft 53 and the blade 56 to rotate until the inclined piece of the second wedge-shaped block 511 abuts against the bottom end of the stopper 59, making the blade 56 in an inclined state. Using the blade 56 in an inclined state, it rotates synchronously with the rotating rod 33 to vertically cut the surrounding seaweed, avoiding the direct cutting of the seaweed close to the spiral blades 34 and further avoiding the entanglement of the seaweed on the spiral blades 34, ensuring that the device can smoothly dive to the specified survey range for survey and improving the use effect of the device.

[0037] A repair component 6 is installed on the side wall of the spiral blade 34; by setting the repair component 6, when the spiral blade 34 is bent and deformed, the second electric push rod 61 is started, and the movable end of the second electric push rod 61 begins to extend. The connecting plate 62 drives the repair ring 63 to synchronously extend along the surface of the spiral blade 34. Since the repair ring 63 abuts and slides against the side wall of the spiral blade 34, during the movement along the spiral blade 34, it will contact the bent and deformed position and repair it. As the repair ring 63 moves to the end of the spiral blade 34, the second electric push rod 61 begins to contract, thereby driving the repair ring 63 to contract and reset. During this process, the bent and deformed position can be repaired again, avoiding affecting the diving direction due to the bending of the spiral blade 34, ensuring the shape of the spiral blade 34, so that it can dive to the specified survey range for surveying, and improving the practicability of the device.

[0038] The positioning component 4 includes a threaded rod 41, which is threadedly connected through the inner bottom wall of the second cavity 35. One end side wall of the threaded rod 41 located inside the second cavity 35 is fixedly connected with a barbed gear 43. The other end of the threaded rod 41 is rotatably connected with a push plate 42. The top end of the threaded rod 41 is fixedly connected with a first spring 44, and one end of the first spring 44 is fixedly connected with the inner top wall of the second cavity 35.

[0039] A plurality of first sliders 45 are symmetrically and slidably connected to the inner bottom wall of the second cavity 35. A second spring 46 is symmetrically and fixedly connected to the side wall of each first slider 45, and each second spring 46 is fixedly connected to the inner side wall of the second cavity 35. A limiting plate 47 is fixedly connected to the side wall of the first slider 45, and one end of the limiting plate 47 is hermetically and slidably connected through the inner side wall of the second cavity 35.

[0040] A first wedge block 48 is fixedly connected to the top wall of one end of the limiting plate 47. Support plates 49 are symmetrically and fixedly connected to the side wall of the load-bearing block 3. A positioning plate 410 is slidably connected through the top end of each support plate 49. Mounting plates 411 are symmetrically and fixedly connected to the side wall of each positioning plate 410.

[0041] A third spring 412 is fixedly connected to the bottom wall of the mounting plate 411, and one end of the third spring 412 is fixedly connected to the top wall of the support plate 49. A limiting hole 413 is opened on the side wall of each positioning plate 410, and a wedge-shaped groove 414 is opened on the inner top wall of the limiting hole 413. The first wedge block 48 abuts and slides against the wedge-shaped groove 414.

[0042] In this solution: The motor 32 works to drive the rotating rod 33 and the spiral blade 34 to rotate. Using the thrust generated by the rotation of the spiral blade 34, the device is driven to move towards the seabed. The device is pushed down by the spiral blade 34, and it dives vertically to a great extent, avoiding displacement of the surveying device under the action of seawater flow and even deviation from the survey area, ensuring that the device can be accurately placed within the survey range and improving the practicality of the device. As the device moves to the seabed, the first stabilization is carried out by the gravity of the weight block 3. As the push plate 42 contacts the seabed, at this time, the push plate 42 will generate a reaction force, driving the threaded rod 41 to compress the first spring 44 and move upward. During this process, since the threaded rod 41 is threadedly connected through the inner bottom wall of the second cavity 35, when the threaded rod 41 moves upward, it will drive the threaded rod 41 to rotate, so that the thorn gear 43 rotates synchronously. During the rotation of the thorn gear 43, under the elastic action of the second spring 46, the first slider 45 will move into the card slot of the thorn gear 43. At this time, the limiting plate 47 will move inward synchronously, so that the first wedge block 48 will gradually leave the inside of the wedge slot 414. Thus, the positioning plate 410 will be pulled downward by the elastic action of the third spring 412, making the positioning plate 410 insert into the seabed for secondary stabilization. The initial position of the first slider 45 is at the maximum diameter of the thorn gear 43. At this time, the second spring 46 is in a compressed state, and at this time, the first wedge block 48 and the limiting plate 47 are respectively located inside the wedge slot 414 and the limiting hole 413 to limit the positioning plate 410. In addition, at this time, the third spring 412 is in a stretched state, and the first wedge block 48 always has a certain distance located inside the wedge slot 414 to facilitate pushing the positioning plate 410 upward to release the stabilization.

[0043] When the survey is completed and the device needs to be recovered, the motor 32 rotates in reverse to generate a reverse thrust and inflates the airbag 11, causing the device to start floating. During this process, under the elastic action of the first spring 44, it will push the threaded rod 41 to move downward. The threaded rod 41 will drive the thorn gear 43 to rotate back to its original position, making the first slider 45 and the limiting plate 47 move to their original positions. During this process, the first wedge block 48 will move along the wedge slot 414, thus pushing the positioning plate 410 upward to release the fixation with the seabed, so that the device starts to float for easy recovery. The elastic force of the first spring 44 is greater than the elastic force of the second spring 46, and the elastic force of the second spring 46 is greater than that of the third spring 412.

[0044] To solve the technical problem that during the diving process of the device, if it passes through the seaweed area, there will be a situation where floating seaweed winds around the spiral blade 34. If the spiral blade 34 is entangled, on the one hand, it cannot dive to the specified range, and on the other hand, it is not convenient for device recovery, as Figure 8 - Figure 10 shown, the following preferred technical solutions are provided:

[0045] The crushing assembly 5 includes a turntable 510, which is embedded and rotates at the top of the load-bearing block 3 and is fixedly connected to the side wall of the rotating rod 33. A plurality of first electric push rods 57 are fixedly connected to the top of the turntable 510 at equal intervals. A chute 51 is provided on the side wall of the rotating rod 33 at equal intervals. A second slider 52 is embedded and slidably connected to the inner wall of each chute 51. A rotating shaft 53 is rotatably connected to the side wall of the second slider 52.

[0046] One end of the rotating shaft 53 is fixedly connected to a connecting block 55. A blade 56 is fixedly connected to the side wall of the connecting block 55. A second wedge block 511 is fixedly connected to the top of the connecting block 55. A torsion spring 54 is fixedly connected to the side wall of the second slider 52. One end of the torsion spring 54 is fixedly connected to the side wall of the connecting block 55, and the torsion spring 54 is sleeved on the outer wall of the adjacent rotating shaft 53.

[0047] Each first electric push rod 57 is rotatably connected to one side of the bottom end of the adjacent second slider 52. An installation ring 58 is fixedly connected to the top of the rotating rod 33. Stopping blocks 59 are fixedly connected to the side wall of the installation ring 58 at equal angles. The stopping block 59 and the adjacent second wedge block 511 are located in the same vertical plane.

[0048] In this solution: If seaweed is entangled with the spiral blade 34, affecting the normal operation of the spiral blade 34, at this time, start the first electric push rod 57. The first electric push rod 57 starts to extend, and drives the blade 56 to move upward along the chute 51 through the connecting block 55. Among them, the first electric push rod 57, the second slider 52, and the blade 56 rotate synchronously with the rotating rod 33. In addition, the chute 51 is provided between two adjacent spiral blades 34, which will not cause the blade 56 to contact the spiral blade 34. In addition, under the action of the torsion spring 54, in the initial state, the cutting edge of the blade 56 faces vertically upward. Therefore, when the seaweed is entangled with the spiral blade 34, during the upward movement of the blade 56 along the chute 51, the blade 56 is used to cut off the entangled seaweed in time, avoiding the influence on the normal operation after the seaweed is entangled with the spiral blade 34; When the blade 56 moves to the upper limit of the chute 51, the second wedge block 511 contacts the bottom end of the stopping block 59, and the first electric push rod 57 is rotatably connected to one side of the bottom end of the connecting block 55. Therefore, during the upward movement of the first electric push rod 57, it will drive the connecting block 55, the rotating shaft 53 and the blade 56 to rotate until the inclined piece of the second wedge block 511 abuts against the bottom end of the stopping block 59, making the blade 56 in an inclined state. Using the inclined blade 56, it rotates synchronously with the rotating rod 33. Since the seaweed grows in the vertical direction, the inclined blade 56 is used to vertically cut the surrounding seaweed, avoiding directly cutting the seaweed close to the spiral blade 34, further avoiding the entanglement of the seaweed with the spiral blade 34, ensuring that the device can smoothly dive to the specified survey range for surveying, and improving the use effect of the device;

[0049] After leaving the seaweed area, the first electric push rod 57 contracts, driving the connecting block 55 and the blade 56 to move downward synchronously. The inclined surface of the second wedge block 511 leaves the bottom wall of the stopper 59, and under the action of the torsion spring 54, the blade 56, the connecting block 55 and the rotating shaft 53 are reset to facilitate subsequent continuous use.

[0050] In order to solve the technical problems that during the diving process of the spiral blade 34, it may be impacted by fish schools and entangled by seaweed due to external factors, resulting in the spiral blade 34 being bent. The bent spiral blade 34 will affect the diving direction and affect the surveying and mapping, as Figure 11 - Figure 12 shown, the following preferred technical solutions are provided:

[0051] The repair component 6 includes a plurality of second electric push rods 61. Each second electric push rod 61 is fixedly connected to the side wall of the rotating rod 33, and a repair ring 63 is slidably connected to the side wall of each spiral blade 34.

[0052] A connecting plate 62 is fixedly connected to the side wall of the repair ring 63, and the movable end of each second electric push rod 61 is fixedly connected to the side wall of the adjacent connecting plate 62.

[0053] In this solution: If the spiral blade 34 is bent due to a collision during rotation and is not repaired in time, it will affect the diving direction of the device. If it leaves the surveying and mapping range, re-surveying is required; when the spiral blade 34 is bent, the second electric push rod 61 is started, and the movable end of the second electric push rod 61 starts to extend. Through the connecting plate 62, the repair ring 63 is driven to extend synchronously along the surface of the spiral blade 34. Since the repair ring 63 abuts against and slides on the side wall of the spiral blade 34, during the movement along the spiral blade 34, it will contact the bent position and repair it. As the repair ring 63 moves to the end of the spiral blade 34, the second electric push rod 61 starts to contract, driving the repair ring 63 to contract and reset. During this process, the bent position can be repaired again. By driving the repair ring 63 with the second electric push rod 61 to reciprocate along the surface of the spiral blade 34, the bent position is continuously repaired so that it is no longer bent, avoiding the influence on the diving direction due to the bending of the spiral blade 34, ensuring the shape of the spiral blade 34, so that it can dive to the specified surveying and mapping range for surveying and mapping, and improving the practicability of the device.
