Description
Technical Field
[0001] This utility model belongs to the field of unmanned surface vessel protection technology, and in particular relates to an unmanned surface vessel protection device. Background Technology
[0002] An unmanned surface vessel (USV) is a device that operates without human intervention, performing tasks in environments such as seas and lakes. Compared to traditional manually piloted vessels, USVs offer greater maneuverability and are capable of handling complex and dangerous missions.
[0003] After completing its mission, the unmanned surface vessel (USV) needs to return to its docking position. To prevent collisions with the dock's edge during this return journey, the current practice is to install crash barriers on the USV. Because these barriers protrude from the vessel's edge, they are designed to prevent deck impacts. However, in practice, it has been observed that with each impact, the crash barriers gradually deform and dent, losing their protective function for the vessel's deck.
[0004] Therefore, existing technologies use buffer structures such as rubber tires installed along the berth of docks to provide cushioning. However, since unmanned surface vessels (USVs) need to perform missions at sea, they all require anti-corrosion paint to prevent seawater corrosion. As the USV's surface continuously rubs against the rubber tires, the integrity of the paint gradually deteriorates, making the USV susceptible to seawater corrosion.
[0005] Furthermore, the anti-corrosion paint spraying process has strict requirements, so it is quite troublesome to repair the anti-corrosion paint coating once it is damaged.
[0006] Therefore, it is crucial to improve the normal berthing of unmanned surface vessels (USVs) by ensuring a safe distance between them and the pier edge during berthing without affecting their normal operation. Utility Model Content
[0007] Based on the above background, the purpose of this utility model is to provide a protective device for unmanned surface vessels.
[0008] To achieve the above objectives, the present invention adopts the following technical solution:
[0009] An unmanned surface vessel (USV) protection device includes a crash barrier structure installed on the USV;
[0010] The crash barrier structure is equipped with several pushing crash barriers and squeezing crash barriers;
[0011] The anti-collision structure includes a hinged push rod structure, which is hinged to a stop rod structure. Several stop wheel structures are installed on the stop rod structure at an angle. The push rod structure pushes the stop rod structure to flip so that the stop wheel structures collide with and roll on the edge of the berth, preventing the unmanned vessel from colliding with or scraping the edge of the berth.
[0012] Preferably, the crash barrier structure includes an arc-shaped barrier section and straight barrier sections integrally formed on both sides of the arc-shaped barrier section, with a horizontal barrier section integrally formed between the straight barrier sections;
[0013] The bottom of the straight section is fixedly connected to several first columns and several second columns that are fixedly installed on the unmanned surface vessel;
[0014] Several third columns, which are fixedly installed on the unmanned vessel, are fixedly connected to the bottom of the arc-shaped railing and the horizontal railing.
[0015] The pushing anti-collision structure is installed on the first column, and the squeezing anti-collision structure is installed on the second column.
[0016] Preferably, the straight section has several hinge slots; a hinge shaft is hinged in the hinge slot;
[0017] The abutment structure includes a telescopic abutment fixedly connected to a hinge shaft, and a abutment sleeve slidably connected to the telescopic abutment.
[0018] The push rod structure includes an electric push rod hinged to the abutment sleeve, and the electric push rod is hinged to the first column.
[0019] Preferably, the pushing end of the electric push rod is fixedly connected to an upper ear seat, and an upper hinge seat that hinges to the upper ear seat is fixedly connected to the outer side wall of the abutment sleeve;
[0020] The bottom of the electric push rod is fixedly connected to a lower ear seat, and the first column is fixedly connected to a lower hinge seat that hinges the lower ear seat.
[0021] Preferably, a spring is sleeved on the telescopic abutment, and a spring seat is fixedly connected to the telescopic abutment. One end of the spring is fixed to the spring seat, and the other end of the spring is at the height of the abutment sleeve.
[0022] Preferably, the abutment structure includes a first abutment, a second abutment, and a third abutment fixedly connected to the outer end of the abutment sleeve;
[0023] The abutment structure also includes a wheel frame structure that rotatably connects the first abutment, the second abutment, and the third abutment. The wheel frame structure includes a first wheel frame portion that rotatably connects to the first abutment, a second wheel frame portion that rotatably connects to the second abutment, and a third wheel frame portion that rotatably connects to the third abutment.
[0024] The first, second, and third wheel frames are arranged at an angle to each other.
[0025] Preferably, the first wheel frame portion and the second wheel frame portion are arranged at a 30-degree angle, and the second wheel frame portion and the third wheel frame portion are arranged at a 30-degree angle.
[0026] Preferably, the compression anti-collision structure includes an arc-shaped rubber plate fixedly connected to the second column.
[0027] Preferably, the structure includes a bow-shaped impact structure;
[0028] The bow-shaped impact structure includes a first bow-shaped portion, a second bow-shaped portion, a third bow-shaped portion, and a fourth bow-shaped portion;
[0029] Concave buffer portions are provided at intervals between the first, second, third, and fourth bow-shaped portions.
[0030] This utility model has the following beneficial effects:
[0031] 1. During operation, when the unmanned surface vessel is about to dock, all the electric push rods facing the shore open. During the opening of the electric push rods, the stop rod structure and the stop wheel structure flip so that the stop wheel structure faces the dock shore. At this time, the unmanned surface vessel is kept at a safe distance by the stop wheel structure and the stop rod structure.
[0032] Subsequently, the unmanned surface vessel (USV) continued to approach the dock until the abutment structure touched the edge of the shore. During the anchoring process, the USV continued to travel a short distance until it came to a stop, during which time the abutment structure rolled against the edge of the dock, maintaining a safe distance from the USV throughout the process.
[0033] Because the abutment structure uses an elastic telescopic mechanism, when the unmanned surface vessel (USV) sways under the action of waves, the abutment structure continuously expands and contracts elastically to match the USV's swaying motion.
[0034] 2. Achieving an arc-shaped impact structure; specifically, the arc-shaped impact structure includes a first arc-shaped section, a second arc-shaped section, a third arc-shaped section, and a fourth arc-shaped section. The first, second, third, and fourth arc-shaped sections, designed in the above manner, ensure that when the unmanned surface vessel is rocked by waves, they are pressed against the shoreline. Furthermore, concave buffer sections are spaced apart between the first, second, third, and fourth arc-shaped sections (i.e., the concave buffer sections deform in coordination with the deformation of the first to fourth arc-shaped sections).
[0035] Therefore, during the elastic deformation of the first, second, third, and fourth bow-shaped sections, they are continuously elastically compressed and then reset, which, combined with the swaying caused by the waves, helps to maintain a high level of stability for the unmanned surface vessel while it is moored.

[0046] Example 1
[0047] like Figure 1-5 As shown, an unmanned surface vessel (USV) protection device includes a crash barrier structure 1 installed on the USV. The crash barrier structure 1 is a conventional crash barrier structure 1 installed on existing USVs. Specifically, the crash barrier structure 1 includes an arc-shaped barrier section 11 and straight barrier sections 12 integrally formed on both sides of the arc-shaped barrier section 11, with a horizontal barrier section 16 integrally formed between the straight barrier sections 12.
[0048] The shape of the aforementioned anti-collision barrier structure 1 corresponds to the shape of the unmanned surface vessel (USV). The anti-collision barrier structure 1 is preferably formed by welding thickened steel pipes to prevent the USV from colliding when it is docked. The anti-collision barrier structure 1 is designed to protect the USV from collisions (the arc-shaped barrier 11, the straight barrier 12, and the horizontal barrier 16 are set to protrude from the side of the USV to protect the side of the USV).
[0049] Meanwhile, the bottom of the straight railing section 12 is fixedly connected to several first pillars 13 and several second pillars 14 that are fixedly installed on the unmanned surface vessel; the bottom of the arc-shaped railing section 11 and the horizontal railing section 16 is fixedly connected to several third pillars 15 that are fixedly installed on the unmanned surface vessel.
[0050] In the existing method, the bottom of the above-mentioned column is equipped with a base, which is fixedly installed at the edge of the unmanned surface vessel.
[0051] The aforementioned crash barrier structure 1 is equipped with several pushing crash barriers 2 and squeezing crash barriers 3. Specifically, the pushing crash barriers 2 are installed on the first upright 13, and the squeezing crash barriers 3 are installed on the second upright 14.
[0052] During operation, when the unmanned surface vessel (USV) docks at the pier, the anti-collision structure 2 is flipped open and pushed against the edge of the pier. This ensures that the USV, the anti-collision barrier structure 1, and the edge of the pier are kept at a safe distance, thus preventing the anti-collision barrier structure 1 from impacting the shape of the USV and preventing the USV from scraping and colliding with it.
[0053] Specifically, the anti-collision structure 2 includes a hinged push rod structure, which is hinged to a stop rod structure. Several stop wheel structures are installed on the stop rod structure at an angle. The push rod structure pushes the stop rod structure to flip so that the stop wheel structure contacts and rolls against the edge of the berthing dock, preventing the unmanned vessel from colliding with or scraping the edge of the berthing dock.
[0054] Example 2
[0055] like Figure 1-5 As shown, in this embodiment, based on the structure of embodiment 1, a plurality of hinge slots A are provided on the straight column section 12; a hinge shaft 21 is hinged in the hinge slot A.
[0056] Meanwhile, the abutment structure includes a telescopic abutment 23 fixedly connected to the hinge shaft 21, and a abutment sleeve 22 slidably connected to the telescopic abutment 23.
[0057] Specifically, the push rod structure includes an electric push rod 25 (the electric push rod 25 is a conventional electric telescopic rod disclosed in the prior art) hinged to the abutment sleeve 22, and the electric push rod 25 is hinged to the first column 13.
[0058] The hinge method is as follows: the pushing end of the electric push rod 25 is fixedly connected to the upper ear seat, and the outer side wall of the abutment sleeve 22 is fixedly connected to the upper hinge seat that hinges the upper ear seat. The two are hinged by a pin.
[0059] Meanwhile, the bottom of the electric push rod 25 is fixedly connected to a lower ear seat, and the first column 13 is fixedly connected to a lower hinge seat that hinges the lower ear seat. The two are hinged together by a pin.
[0060] Meanwhile, a spring 24 is sleeved on the telescopic abutment 23, and a spring 24 seat is fixedly connected to the telescopic abutment 23. One end of the spring 24 is fixed on the spring seat, and the other end of the spring 24 is at the height of the abutment sleeve 22 (specifically at the opening of the abutment sleeve 22).
[0061] During operation, when the unmanned surface vessel (USV) is about to dock, all the electric push rods 25 facing the shore open. During the opening of the electric push rods 25, the stop rod structure and the stop wheel structure flip up so that the stop wheel structure faces the dock shore. At this time, the USV is kept at a safe distance by the stop wheel structure and the stop rod structure.
[0062] Subsequently, the unmanned surface vessel (USV) continued to approach the dock until the abutment structure touched the edge of the shore. During the anchoring process, the USV continued to travel a short distance until it came to a stop, during which time the abutment structure rolled against the edge of the dock, maintaining a safe distance from the USV throughout the process.
[0063] Because the abutment structure adopts an elastic telescopic method, when the unmanned surface vessel (USV) sways under the action of waves, the abutment structure continuously elastically expands and contracts in coordination with the swaying of the USV (specifically, under the action of waves, the USV sways and rocks; when it sways toward the shore, the telescopic abutment 23 retracts into the abutment sleeve 22, and the spring 24 is compressed).
[0064] Example 3
[0065] like Figure 1-5 As shown, based on the structure of Embodiment 2, the above-mentioned abutment structure includes a first abutment 26, a second abutment 27, and a third abutment 28 fixedly connected to the outer end of the abutment sleeve 22.
[0066] Specifically, the abutment structure also includes a wheel frame structure that rotatably connects the first abutment wheel 26, the second abutment wheel 27, and the third abutment wheel 28. The wheel frame structure includes a first wheel frame portion rotatably connected to the first abutment wheel, a second wheel frame portion rotatably connected to the second abutment wheel, and a third wheel frame portion rotatably connected to the third abutment wheel. The first wheel frame portion, the second wheel frame portion, and the third wheel frame portion are arranged at an included angle. Specifically, the first wheel frame portion and the second wheel frame portion, and the second wheel frame portion and the third wheel frame portion, are arranged at a 30-degree angle.
[0067] The first wheel frame and the second wheel frame, as well as the second wheel frame and the third wheel frame, are integrally formed.
[0068] The purpose of arranging the first abutment wheel 26, the second abutment wheel 27, and the third abutment wheel 28 at an included angle is:
[0069] Because the unmanned surface vessel (USV) does not travel in a straight line during mooring, it sways under the influence of waves. This swaying causes changes in the angles of the first abutment wheel 26, the second abutment wheel 27, and the third abutment wheel 28. Therefore, to prevent the abutment wheels from failing to stably contact and roll on the shoreline due to the swaying of the USV, the first abutment wheel 26, the second abutment wheel 27, and the third abutment wheel 28 are set at three different angles. This ensures that if the USV sways, any one of the three abutment wheels can effectively contact the shoreline because of the included angle, thus coordinating with the USV's mooring movement.
[0070] However, if only one unmanned vessel is used for anchoring, the swaying of the unmanned vessel can easily cause the angle between the anchoring vessel and the shoreline to change, making it impossible to make proper contact and anchor.
[0071] After the unmanned surface vessel stops, the anti-wheel structure retracts and resets.
[0072] Example 4
[0073] like Figure 1-5As shown, this embodiment is based on the structure of embodiment 3. When the unmanned surface vessel (USV) stops and resets, the anti-ship structure also resets. To prevent the USV from crashing into the shoreline due to wave impact, the aforementioned anti-collision structure 3 includes an arc-shaped rubber plate fixedly connected to the second column 14. When the anti-ship structure retracts and resets, the arc-shaped rubber plate contacts the shoreline.
[0074] Specifically, it includes an arc-shaped impact structure; more specifically, the arc-shaped impact structure includes a first arc-shaped portion 31, a second arc-shaped portion 32, a third arc-shaped portion 33, and a fourth arc-shaped portion 34. The first arc-shaped portion 31, the second arc-shaped portion 32, the third arc-shaped portion 33, and the fourth arc-shaped portion 34, designed with the above structure, ensure that when the unmanned surface vessel is rocked by waves, the first arc-shaped portion 31, the second arc-shaped portion 32, the third arc-shaped portion 33, and the fourth arc-shaped portion 34 are pressed against the shoreline. Furthermore, due to the concave buffer portions B spaced between the first arc-shaped portion 31, the second arc-shaped portion 32, the third arc-shaped portion 33, and the fourth arc-shaped portion 34 (i.e., the concave buffer portions B deform in coordination with the deformation of the first arc-shaped portion to the fourth arc-shaped portion),...
[0075] Therefore, during the elastic deformation and reset of the first bow-shaped part 31, the second bow-shaped part 32, the third bow-shaped part 33, and the fourth bow-shaped part 34, the unmanned surface vessel is rocked by the waves to prevent it from hitting the shoreline. This method helps maintain the high stability of the unmanned surface vessel while it is moored.
[0076] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
