Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary tools for magnetic force measurement on unmanned vessels, specifically a support probe suitable for magnetic force measurement on unmanned vessels. Background Technology

[0002] With the rapid development of unmanned systems and artificial intelligence technologies, unmanned surface vessels (USVs) and other intelligent systems are being widely used in naval and civilian fields such as maritime rights protection, maritime monitoring, and marine resource development. After research and development and production, USV platforms are widely used in military missions such as anti-submarine warfare, mine clearance, and armed patrols, as well as in civilian fields such as underwater mapping, water quality sampling, maritime search and rescue, and scientific research exploration.

[0003] Compared to manned vessels, unmanned vessels can reduce personnel risks, operate in various aquatic environments around the clock, have strong environmental adaptability, and effectively improve operational efficiency because they do not require human operation.

[0004] Currently, marine gravity and magnetic measurements primarily rely on large survey vessels as platforms for marine gravimeters. However, the relocation of these large vessels to the grid survey area is both energy-intensive and time-consuming, and they are also unable to conduct gravity measurements in shallow coastal waters or complex waters near remote islands and reefs. Using small surface survey vessels with a depth of 5-8 meters is an effective way to improve measurement efficiency. In particular, using unmanned surface survey vessels will significantly improve efficiency while avoiding the safety hazards of boarding operations and saving human resources.

[0005] The accuracy of marine magnetic field measurements is often affected by external factors, primarily the influence of the ship's hull and the magnetic detection equipment. Under normal conditions, the ship's hull, being a ferromagnetic object, can interfere with the detection equipment during marine magnetic field measurements. This interference, on top of the interference from the magnetic detection equipment itself, further affects the accuracy of the measurements. Summary of the Invention

[0006] To overcome the shortcomings of the prior art, this application provides a support probe suitable for magnetic field measurement of unmanned vessels. By connecting two support rods B and one support rod A made of carbon fiber material with a connector, a suspended pyramidal support is formed at the bow of the unmanned vessel using the two support rods B and the support rod A. This support can support the magnetic field measurement component, which is supported by a measuring probe at one end of an outward sleeve made of glass fiber material, in a relatively stable state in the air. This ensures that the magnetic field measurement component is not affected by the metal of the unmanned vessel hull when detecting marine magnetic field.

[0007] The technical solution adopted by the embodiments of this application to solve its technical problem is:

[0008] A support rod suitable for magnetic field measurement on unmanned vessels includes a support rod B, a support rod A, and a connector, wherein there are two support rods B;

[0009] Support rod A is located directly below the center area of ​​the two support rods B; and

[0010] The connector is connected to one end of two support rods B and one support rod A;

[0011] One end of the support rod A is plugged into an outward sleeve, and a measuring probe is installed at one end of the outward sleeve. A magnetic measurement component is internally assembled on the side of the measuring probe away from the outward sleeve. Both support rod A and support rod B are made of carbon fiber, and the outward sleeve is made of glass fiber. The other ends of the two support rods B are connected to the two sides of the top of the bow of the unmanned vessel, and the other end of support rod A is connected to the side surface of the tip of the bow of the unmanned vessel, so that support rod A and the two support rods B form a pyramid shape in space, and support rod A and support rod B, and the two support rods B form a triangle in the plane, supporting the magnetic measurement component away from the unmanned vessel, and performing marine magnetic detection on the measuring probe.

[0012] Preferably, both ends of the two support rods B and one end of the support rod A are assembled with pipe heads, and one end of each pipe head on the support rods B and A is hinged to a fixing seat. A liner is attached to the surface of the fixing seat, and the fixing seat is assembled and fixed to the unmanned vessel hull by bolts, so that the liner is supported between the surface of the unmanned vessel hull and the surface of the fixing seat.

[0013] Preferably, the connector includes a fixed sleeve, the outer wall of which is machined with two sleeve lugs, the end of the support rod A away from the fixed seat is sleeved inside the fixed sleeve, and the ends of the two support rods B away from the fixed seat are respectively hinged to the two sleeve lugs.

[0014] Preferably, both support rods B and one support rod A are arranged in two sections, and the inner side of the connection point of the two sections is provided with an inner liner tube.

[0015] Preferably, the outer wall of the inner liner tube and the inner wall at the connection point of the two sections of support rod B and support rod A are all polished to remove the release agent, and are then mated with E44 or the same type of resin as support rod A and support rod B, and the inner liner tube is inserted into the connection point of the two sections of support rod A and support rod B by more than 150mm.

[0016] Preferably, the length of the extended sleeve inserted into one end of the support rod A is more than 150mm. The outer wall of the extended sleeve inserted into one end of the support rod A and the inner wall area of ​​the support rod A receiving the extended sleeve are both polished to remove the release agent, and are then connected with E44 or the same type of resin as the support rod A and support rod B.

[0017] Preferably, the measuring probe includes probe A and probe B. Probe A includes a support base plate, and two symmetrical C-shaped clamps are machined on one side of the support base plate. Probe B includes a C-shaped buckle, and two clamp plates are integrally formed on the side of the C-shaped buckle away from the C-shaped opening. The support base plate is assembled between the two clamp plates. One end of the outward sleeve is inserted between the two probes A. Both ends of the two probes A are assembled and fixed by bolts. The magnetic force measuring component is fastened to the inside of the C-shaped buckle.

[0018] Preferably, both ends of the support plate are machined with arc-shaped grooves, and three bolts pass through the two clamping plates and the support plate. The three bolts are arranged in a straight line, and the bolts at both ends pass through the interior of the two arc-shaped grooves respectively. The support clamping plate rotates around the central bolt.

[0019] In summary, this utility model has at least one of the following beneficial technical effects:

[0020] Firstly, this utility model provides a support probe for magnetic force measurement on unmanned vessels. By connecting two support rods B and one support rod A made of carbon fiber material through a connector, a suspended pyramidal support is formed at the bow of the unmanned vessel using the two support rods B and one support rod A. This support can support the magnetic force measurement component, which is made of glass fiber material and has one end supported by the measuring probe, in a relatively stable state in the air. This ensures that the magnetic force measurement component is not affected by the metal of the unmanned vessel hull when detecting marine magnetic force, thus guaranteeing the detection accuracy.

[0021] Secondly, the present invention provides a support probe for magnetic force measurement of unmanned vessels. By setting two support rods B and one support rod A into two sections, an inner liner is set between the connection points of the different sections. After grinding the connection area between the inner liner and support rod A and the connection area between the inner liner and support rod B, the sections are bonded with resin. The lengths of support rod B and support rod A can be controlled according to actual needs, making it suitable for actual application environments and application requirements.

[0022] Thirdly, the support probe rod of this utility model for magnetic force measurement of unmanned ships is configured into two parts: probe A, which is connected to one end of the outward sleeve, and probe B, which is connected to the magnetic force measurement component. By machining arc-shaped grooves at both ends of the support plate on probe A, and using three bolts for assembling the support plate and the clamping plate to support probe B, the magnetic force measurement component is rotated on one side of probe A. This facilitates the fit with the overall shape of the unmanned ship and allows the magnetic force measurement component to be at the angle of overall operation. Attached Figure Description

[0033] Example 1:

[0034] A support probe suitable for magnetic field measurement on unmanned vessels, such as Figures 1-9 As shown, it includes two support rods B5, support rod A4 and a connector 3 connected to one end of the two support rods B5 and one support rod A4. One end of support rod A4 is plugged into an extension sleeve 2. One end of extension sleeve 2 is provided with a measuring probe 1. The measuring probe 1 is internally assembled with a magnetic force measuring component 8 on the side away from extension sleeve 2.

[0035] like Figure 1 , Figure 2 and Figure 8 As shown, both ends of the two support rods B5 and one end of the support rod A4 are assembled with tube heads 10. One end of the tube head 10 on the support rods B5 and A4 is hinged to a fixing seat 6. A liner 11 is attached to the surface of the fixing seat 6.

[0036] Among them, support rod A4 and support rod B5 are both made of carbon fiber material, and the outer sleeve 2 is made of glass fiber material. Furthermore, the relevant components (such as measuring probe 1 and connector 3) used in support rod A4, the two support rods B5 and the outer sleeve 2 can all be made of carbon fiber material and glass fiber material to ensure that the magnetic force measurement component 8 is not affected by the metal of the unmanned vessel 7 when it detects marine magnetic force at the front end of the unmanned vessel 7.

[0037] Secondly, the mounting base 6 is assembled and fixed to the unmanned vessel hull 7 by bolts, so that the liner 11 is supported between the surface of the unmanned vessel hull 7 and the surface of the mounting base 6. By connecting one end of the two support rods B5 to the two sides of the top of the bow of the unmanned vessel hull 7, and one end of the support rod A4 to the side surface of the tip of the bow of the unmanned vessel hull 7, the support rod A4 and the two support rods B5 form a pyramid shape in space. The support rod A4 is located directly below the central area of ​​the two support rods B5, which can keep the support rods A4 and B5 and the two support rods B5 forming a triangle in the plane, supporting the magnetic force measurement component 8 away from the unmanned vessel hull 7, keeping the magnetic force measurement component 8 connected to the measurement probe 1 in a relatively stable state in the air, which facilitates the magnetic force measurement component 8 to perform marine magnetic force detection on the measurement probe 1.

[0038] Furthermore, the connector 3 includes a fixed sleeve 301, and two sleeve lugs 302 are machined on the outer wall of the fixed sleeve 301. By having the end of the support rod A4 away from the fixed seat 6 sleeved inside the fixed sleeve 301, the tube ends 10 of the two support rods B5 away from the fixed seat 6 are respectively hinged to the two sleeve lugs 302, which can support the two ends of the support rods B5 and A4 to be connected between the unmanned hull 7 and the connector 3.

[0039] This utility model discloses a support probe for magnetic force measurement of an unmanned surface vessel (USV). It connects two support rods B5 and one support rod A4 via a connector 3. One end of each support rod B5 is connected to the two sides of the top of the bow of the USV 7, and the other end is hinged to two sleeve lugs 302. One end of support rod A4 is connected to the side surface of the tip of the bow of the USV 7, and the other end is fitted inside a fixed sleeve 301. This allows the two support rods B5 and one support rod A4 to form a suspended pyramidal support at the bow of the USV 7, supporting the magnetic force measurement component 8, which is supported by the measuring probe 1 at one end of the outward-extending sleeve 2, in a relatively stable state in the air. This ensures that the magnetic force measurement component 8 is not affected by the metal of the USV 7 hull when detecting marine magnetic force at the forward end of the USV 7.

[0040] Example 2:

[0041] Based on Example 1, such as Figure 1 , Figure 2 and Figure 9 As shown, this embodiment is the internal structure of support rod B5 and support rod A4. Both support rods B5 and support rod A4 are set in two sections, and the inner side of the connection point of the two sections is provided with an inner liner tube 12.

[0042] Among them, by grinding, the release agent on the outer wall of the inner liner tube 12 and the inner wall at the connection point of the two sections of the support rod B5 and support rod A4 is removed, and E44 (E44 epoxy resin) or the same type of resin as the support rod A4 and support rod B5 is used for butt joint (the inner liner tube 12 is inserted into the connection point of the two sections of the support rod A4 and support rod B5 by more than 150mm). The two sections of the support rod B5 or support rod A4 can be butt jointed with the inner liner tube 12, ensuring a bonding rate of more than 80%, with no misalignment, no excess glue, and no gaps at the joint;

[0043] Secondly, by inserting the extended sleeve 2 into the inside of one end of the support rod A4 by more than 150mm, and by grinding the outer wall of the extended sleeve 2 inserted into the support rod A4 and the inner wall area of ​​the support rod A4 receiving the extended sleeve 2, the release agent is removed. After connecting the inner liner tube 12 and the support rod A4, and the inner liner tube 12 and the support rod B5 with E44 or the same type of resin as the support rod A4 and support rod B5, the bonding rate is ensured to be more than 80%, and the straightness of the extended sleeve 2 and the support rod A4 is guaranteed.

[0044] At the same time, it should be noted that although the outer sleeve 2 is made of glass fiber material, it is easy to have elastic fibers inside, but the elastic fibers need to be completely eliminated. In addition, during the process of making the outer sleeve 2 using glass fiber material, there must be no conductive material inside the outer sleeve 2.

[0045] In addition, the two support rods B5 and one support rod A4 can be made into multiple sections, and the sections are connected by inner liner tubes 12. In this state, the length of the inner liner tube 12 extending into the support rod A4 or support rod B5 can be adjusted according to the actual installation requirements. The treatment methods used before bonding the inner liner tube 12 and the support rod A4 or support rod B5 and the materials used during bonding are all the same as the above-mentioned E44 or the same type of resin as support rod A4 and support rod B5.

[0046] This utility model discloses a support probe for magnetic force measurement of unmanned vessels. By setting the two support rods B5 and one support rod A4, which constitute the main body of this application, into two sections, an inner liner tube 12 is set between the connection points of the different sections. After grinding the connection areas of the inner liner tube 12 and the support rod A4, and the connection areas of the inner liner tube 12 and the support rod B5, resin bonding is used. The lengths of the support rods B5 and A4 can be controlled according to actual needs to connect the two support rods B5 and the support rod A4 between the connector 3 and the unmanned vessel hull 7, which is suitable for actual application environments and application requirements.

[0047] Example 3:

[0048] Based on Examples 1 and 2, such as Figures 1-5 As shown, this embodiment is the specific structure of the measuring probe 1. The measuring probe 1 includes probe A101 and probe B102. Probe A101 includes a support plate 1011. Two C-shaped clamps 1012 are machined on one side of the support plate 1011. Probe B102 includes a C-shaped buckle 1021. Two clamp plates 1022 are integrally formed on one side of the C-shaped buckle 1021.

[0049] The clamp plate 1022 is located on the side of the C-type buckle 1021 away from the C-type opening. By assembling the support plate 1011 between the two clamp plates 1022, one end of the outward sleeve 2 is inserted between the two probes A101. Both ends of the two probes A101 are fixed by bolts. After the magnetic force measurement assembly 8 is fastened to the inside of the C-type buckle 1021, the support rod A4 can be suspended in the air by the outward sleeve 2 and the measuring probe 1 on the magnetic force measurement assembly 8 to carry out marine magnetic force measurement work.

[0050] Meanwhile, the connection between the magnetic force measuring component 8 and the C-type buckle 1021 can also be achieved by connecting a bolt at the corner of the C-type buckle 1021 away from the clamp plate 1022, reducing the opening of the probe B102, and fixing the magnetic force measuring component 8 to the inside of the C-type buckle 1021.

[0051] Secondly, in order to control the angle of the magnetic force measurement component 8 when measuring the ocean magnetic force, such as Figures 3 to 5As shown, both ends of the support plate 1011 are machined with arc-shaped grooves 9. Three bolts pass through the two clamping plates 1022 and the support plate 1011. By arranging the three bolts in a straight line, the bolts at both ends pass through the interior of the two arc-shaped grooves 9 respectively, which can support the clamping plate 1022 to rotate around the central bolt, thereby adjusting the tilt angle of the probe B102 on the side of the probe A101, and thus controlling the angle of the magnetic force measurement component 8 inside the probe B102.

[0052] Meanwhile, after adjusting the probe B102 to a suitable angle, when the two clamping plates 1022 are narrowed by using bolts (a nut needs to be connected to one end of the bolt), the support plate 1011 between the two clamping plates 1022 can be clamped, thereby achieving the effect of fixing the probe B102 to one side of the probe A101.

[0053] This utility model discloses a support probe rod suitable for magnetic force measurement on unmanned vessels. The measuring probe 1 is configured as two parts: probe A101 connected to one end of the outward sleeve 2 and probe B102 connected to the magnetic force measurement assembly 8. Arc-shaped grooves 9 are machined at both ends of the support plate 1011 on probe A101. The probe B102 is supported by three bolts (with the central bolt as the support point and the two bolts at both ends as the limit) used for assembling the support plate 1011 and the clamping plate 1022. This allows the magnetic force measurement assembly 8 to rotate on one side of probe A101. According to the usage requirements of the magnetic force measurement assembly 8 and in combination with the overall shape of the unmanned vessel hull 7, the magnetic force measurement assembly 8 can be positioned at the working angle.

[0054] Meanwhile, when adjusting the angle of probe B102 on the side of probe A101, tighten the nuts at one end of the three bolts on the support plate 1011 and the clamp plate 1022 to fix the support plate 1011 and the clamp plate 1022, so that probe A101 and probe B102 can be fixed, and the magnetic force measurement assembly 8 can be made to be in a stable working state.

[0055] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
