Description

Technical Field

[0001] The present invention relates to the technical field of ocean surveying and mapping, and in particular to an ocean surveying and mapping positioning device. Background Art

[0002] Marine surveying and mapping includes marine positioning, marine geodesy, underwater topography measurement and other aspects; marine surveying and mapping positioning devices provide basic data support for these surveying and mapping tasks by providing accurate location information. For example, when drawing a seabed topographic map, it is necessary to know the exact location of the measurement point to ensure the accuracy of the topographic map.

[0003] For example, the announcement number CN221811582U proposes a positioning device for an ocean surveying instrument. It includes a counterweight frame, which has a plurality of counterweight slots, in which counterweight blocks are slidably arranged, and in which two sets of fixed pop-up mechanisms are symmetrically arranged; a fixed plate, which is arranged on the counterweight frame; and a mounting block, which is arranged on the fixed plate and has a plurality of mounting holes for mounting the ocean surveying instrument. The device is provided with a fixed pop-up mechanism, and before the entire positioning device is sunk underwater, the required number of counterweight blocks are inserted into the counterweight slots. During insertion, the fixed block rotates to compress the ejection spring, and after releasing the ejection spring, the ejection spring extends, and the fixed block rotates in the opposite direction to be inserted into the fixed slot. When the positioning device sinks underwater, the counterweight block is prevented from separating from the device.

[0004] At present, during the surveying and mapping of marine areas, whether the instrument observes the seabed vertically directly affects the data quality. If the position cannot be kept within the predetermined range, the surveyed data will deviate from the actual data, and the device is positioned close to the weight block, while there are many uncertain factors on the seabed. For example, the device may be affected by fish schools, causing the device to move, which will have an impact. In addition, during the dive of the device, if it passes through an algae area, floating seaweed may entangle the spiral blades. If the spiral blades are entangled, on the one hand, they cannot dive to the specified range, and on the other hand, it is not convenient for the device to be recovered. Moreover, due to the impact of fish schools and external factors such as seaweed entanglement during the dive, the spiral blades may bend. The bent spiral blades will affect the diving direction and the surveying and mapping.

In this process, the bending deformation position can be repaired again to avoid affecting the diving direction due to the bending of the spiral blade, ensure the shape of the spiral blade, and then dive to the specified surveying range for surveying and mapping, thereby improving the practicality of the device.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] In order to solve the problem that whether the instrument is vertical to the seabed directly affects the data quality during the sea area surveying and mapping process, if the position cannot be kept within the predetermined range, the surveyed data will deviate from the actual data, and the device is positioned close to the weight block 3, while there are many uncertain factors on the seabed, such as the influence of fish schools, which may cause the device to move, and there are technical problems such as Figure 1 - Figure 7 As shown, the following preferred technical solutions are provided: A marine surveying and positioning device comprises a bearing plate 1, a waterproof cover 2 is installed on the top of the bearing plate 1, and a marine surveying and mapping device is installed inside the waterproof cover 2. The marine surveying and mapping device belongs to the prior art and is the main instrument required for marine surveying and mapping. An air bag 11 is symmetrically fixedly connected to the bottom of the bearing plate 1. Due to deep-sea operations, the material used in the air bag 11 has sufficient pressure resistance, and an air pump and an air storage cavity are provided on the bearing plate 1. In the initial state, there is no gas inside the air bag 11. When the device needs to be recovered, the air pump is used to pump the gas in the air storage cavity into the air bag 11, so that the air bag 11 expands, so that the buoyancy of the device is greater than the gravity of the device, and then it starts to float to the sea surface. Cables 12 are symmetrically fixedly connected to the bottom of the bearing plate 1, and two groups of cables 12 are fixedly connected to a weight block 3. Sufficient gravity is generated by the weight block 3 to overcome the buoyancy of seawater and make the device sink to the required depth. At the seabed location for ocean surveying, a first cavity 31 is opened in the inner wall of the weight block 3, a motor 32 is fixedly connected to the inner wall of the first cavity 31, a rotating rod 33 is fixedly connected to the output end of the motor 32, one end of the rotating rod 33 passes through the top wall and 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 in the inner wall of the weight block 3, a positioning component 4 is installed inside the second cavity 35, by setting the positioning component 4, the motor 32 works to drive the rotating rod 33 and the spiral blades 34 to rotate, and the thrust generated by the rotation of the spiral blades 34 is used to drive the device to move toward the seabed, and the spiral blades 34 push the device downward, and it dives in the vertical direction to a great extent, avoiding the displacement of the surveying and mapping device under the action of seawater flow, or even deviating from the surveying and mapping area, ensuring that the device can be ready to be put into the surveying and mapping range, and improving the practicality of the device.

[0022] The side wall of the rotating rod 33 is provided with a crushing assembly 5, through which the first electric push rod 57 is started, the first electric push rod 57 begins to extend, and the blade 56 is driven by the connecting block 55 to start moving upward along the slide groove 51. When the blade 56 moves to the upper limit position of the slide groove 51, the second wedge block 511 contacts the bottom end of the stop block 59, and the first electric push rod 57 is rotatably connected to one side of the bottom end of the connecting block 55, so that as the first electric push rod 57 moves upward, 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 contacts the bottom end of the stop block 59, so that the blade 56 is in an inclined state, and the inclined blade 56 is used to rotate synchronously with the rotating rod 33 to vertically cut the surrounding seaweed, avoid the seaweed being directly cut close to the spiral blade 34, and further avoid the seaweed being entangled with the spiral blade 34, so as to ensure that the device can smoothly dive into the specified surveying and mapping range for surveying and mapping, thereby improving the use effect of the device.

[0023] A repair component 6 is installed on the side wall of the spiral blade 34; by setting up 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, driving the repair ring 63 through the connecting plate 62 to extend synchronously along the surface of the spiral blade 34. Since the repair ring 63 slides against the side wall of the spiral blade 34, it will contact and repair the bending deformation position during the movement along the spiral blade 34. 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. In this process, the bending deformation position can be repaired again to avoid affecting the diving direction due to the bending of the spiral blade 34, ensure the shape of the spiral blade 34, and then dive to the specified surveying range for surveying, thereby improving the practicality of the device.

[0024] The positioning assembly 4 includes a threaded rod 41, which is threadedly connected to the bottom wall of the second cavity 35, and a thorn gear 43 is fixedly connected to the side wall of one end of the threaded rod 41 located inside the second cavity 35. The other end of the threaded rod 41 is rotatably connected to a push plate 42, and a first spring 44 is fixedly connected to the top of the threaded rod 41. One end of the first spring 44 is fixedly connected to the top wall of the second cavity 35.

[0025] The inner bottom wall of the second cavity 35 is symmetrically and slidably connected with a plurality of first sliders 45, the side wall of each first slider 45 is symmetrically and fixedly connected with a second spring 46, each second spring 46 is fixedly connected to the inner side wall of the second cavity 35, the side wall of the first slider 45 is fixedly connected with a limit plate 47, and one end of the limit plate 47 is sealed and slidably connected with the inner side wall of the second cavity 35.

[0026] The top wall at one end of the limiting plate 47 is fixedly connected to a first wedge block 48, the side wall of the load-bearing block 3 is symmetrically fixedly connected to a support plate 49, the top of each support plate 49 is slidably connected to a positioning plate 410, and the side wall of each positioning plate 410 is symmetrically fixedly connected to a mounting plate 411.

[0027] 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 provided on the side wall of each positioning plate 410, and a wedge-shaped groove 414 is provided on the top wall of the limiting hole 413. The first wedge block 48 slides against the wedge groove 414.

[0028] In this solution: the motor 32 is used to drive the rotating rod 33 and the spiral blade 34 to rotate, and the thrust generated by the rotation of the spiral blade 34 is used to drive the device to move toward the seabed, and the spiral blade 34 is used to push the device downward, and it dives in the vertical direction to a great extent, avoiding the displacement of the surveying and mapping device under the action of the flow of seawater, or even deviating from the surveying and mapping area, ensuring that the device can be ready to be put into the surveying and mapping range, and improving the practicality of the device; as the device moves to the seabed, the weight block 3 is used for the first gravity to perform the first stabilization, and as the push plate 42 contacts the seabed, the push plate 42 will generate a reaction force, driving the threaded rod 41 to compress the first spring 44 and move upward. In this process, since the threaded rod 41 is threadedly connected to the bottom wall of the second cavity 35, the threaded rod 41 will be driven to rotate during the upward movement of the threaded rod 41, thereby causing the thorn gear 43 to rotate synchronously. During the rotation process, under the elastic action of the second spring 46, the first slider 45 will move to the inside of the slot of the thorn gear 43, and the limiting plate 47 will move synchronously inward, so that the first wedge block 48 will gradually leave the inside of the wedge slot 414, so that the positioning plate 410 will pull the positioning plate 410 downward under the elastic action of the third spring 412, so that the positioning plate 410 is inserted into the seabed for secondary stabilization; wherein the initial position of the first slider 45 is located 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 in the wedge slot 414 and the limiting hole 413, limiting the positioning plate 410, in addition, at this time the third spring 412 is in a stretched state, and the first wedge block 48 is always located in the inside of the wedge slot 414 for a certain distance, so as to facilitate the subsequent pushing of the positioning plate 410 upward to release the stabilization; When the surveying is completed and the device needs to be recovered, the motor 32 reverses to generate reverse thrust and inflates the airbag 11, causing the device to begin to float. During this process, under the elastic action of the first spring 44, the threaded rod 41 will be pushed downward, and the threaded rod 41 will drive the thorn gear 43 to reset and rotate, so that the first slider 45 and the limit plate 47 move to their original positions. During this process, the first wedge block 48 will move along the wedge groove 414, thereby pushing the positioning plate 410 upward and releasing the fixation with the seabed, so that the device begins to float for easy recovery, wherein 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 the third spring 412.

[0029] In order to solve the technical problem that when the device is submerged, if it passes through the seaweed area, there will be floating seaweed entangled with the spiral blades 34. If the spiral blades 34 are entangled, on the one hand, it cannot dive to the specified range, and on the other hand, it is not convenient to recover the device. Figure 8 - Fig.10 As shown, the following preferred technical solutions are provided: The crushing assembly 5 includes a turntable 510, which is embedded and rotated at the top of the weight block 3 and 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. The side wall of the rotating rod 33 is provided with sliding grooves 51 at equal intervals. The inner wall of each sliding groove 51 is embedded with a second sliding block 52 for sliding connection. The side wall of the second sliding block 52 is rotatably connected to a rotating shaft 53.

[0030] A connecting block 55 is fixedly connected to one end of the rotating shaft 53, 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 sliding block 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.

[0031] Each first electric push rod 57 is rotatably connected to one side of the bottom end of the adjacent second slider 52, a mounting ring 58 is fixedly connected to the top of the rotating rod 33, a stopper 59 is fixedly connected to the side wall of the mounting ring 58 at an equal angle, and the stopper 59 and the adjacent second wedge block 511 are located in the same vertical plane.

[0032] In this solution: if the seaweed and the spiral blade 34 are entangled, affecting the normal operation of the spiral blade 34, the first electric push rod 57 is started at this time, the first electric push rod 57 begins to extend, and drives the blade 56 to start moving upward along the slide groove 51 through the connecting block 55, wherein the first electric push rod 57, the second slider 52, and the blade 56 rotate synchronously with the rotating rod 33, and the slide groove 51 is opened between two adjacent spiral blades 34, so that the blade 56 will not contact the spiral blade 34. In addition, under the action of the torsion spring 54, the blade 56 is facing vertically upward in the initial state, so that when the seaweed and the spiral blade 34 are entangled, the blade 56 is used to cut off the entangled seaweed in time during the process of moving upward along the slide groove 51, so as to avoid the seaweed and the spiral blade 34 being entangled and affecting the normal operation; When the blade 56 moves to the upper limit position of the slide slot 51, the second wedge 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, so that as the first electric push rod 57 moves upward, 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 contacts the bottom end of the stopper 59, so that the blade 56 is in an inclined state. The inclined blade 56 is used to rotate synchronously with the rotating rod 33. Since the seaweed grows in a vertical direction, the inclined blade 56 is used to vertically cut the surrounding seaweed, so as to avoid the seaweed being directly cut off near the spiral blade 34, and further avoid the seaweed from entangled with the spiral blade 34, so as to ensure that the device can smoothly dive into the specified surveying and mapping range for surveying and mapping, thereby improving the use effect of the device; 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, and the inclined surface of the second wedge block 511 leaves the bottom wall of the block 59, and under the action of the torsion spring 54, the blade 56, the connecting block 55 and the rotating shaft 53 are reset for subsequent continued use.

[0033] In order to solve the technical problem that the spiral blade 34 may be bent due to the impact of fish and entanglement of seaweed during the diving process, the bent spiral blade 34 will affect the diving direction and affect the surveying and mapping, such as Fig.11 - Fig.12 As shown, the following preferred technical solutions are provided: 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 . A repair ring 63 is slidably connected to the side wall of each spiral blade 34 .

[0034] The side wall of the repair ring 63 is fixedly connected with a connecting plate 62 , and the movable end of each second electric push rod 61 is fixedly connected to the side wall of the adjacent connecting plate 62 .

[0035] In this solution, if the spiral blade 34 collides during rotation and causes the spiral blade 34 to bend and deform, if it is not repaired in time, it will affect the diving direction of the device. If it leaves the surveying range, it needs to be re-surveyed. 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, driving the repair ring 63 through the connecting plate 62 to extend synchronously along the surface of the spiral blade 34. Since the repair ring 63 slides against the side wall of the spiral blade 34, it will contact the bending deformation position during the movement along the spiral blade 34 and It is repaired, and as the repair ring 63 moves to the end of the spiral blade 34, the second electric push rod 61 begins to shrink, thereby driving the repair ring 63 to shrink and reset. In this process, the bent and deformed position can be repaired again. The repair ring 63 is driven by the second electric push rod 61 to move back and forth along the surface of the spiral blade 34, thereby continuously repairing the bent and deformed position so that it no longer bends, avoiding the bending of the spiral blade 34 and affecting the diving direction, ensuring the shape of the spiral blade 34, so that it can dive to the specified surveying range for surveying, thereby improving the practicality of the device.
