Description

Technical Field

[0001] This utility model relates to the field of waterway monitoring equipment technology, and in particular to a foldable obstacle avoidance observation frame. Background Technology

[0002] The obstacle avoidance observation frame for ships is an observation point installed at the front of the bridge, on both sides of the deck, or in the middle of the hull. It is specifically designed for the scenario of ship obstacle identification in waterways. It provides stable support and multi-angle adjustment for waterway observation instruments, and avoids the obstruction of the ship itself and the interference of the waterway environment through mechanical structure, so as to ensure that the instruments accurately identify waterway obstacles. During the ship's navigation in the waterway, waterway obstacle identification is a core link to ensure navigation safety.

[0003] In the prior art, such as Chinese Patent Publication No. CN210662118U, a bracket for installing a ship monitoring remote sensing device is disclosed. It includes a base, with a cylindrical fixing rod fixedly installed at the center of the upper surface of the base. A second sleeve and a first sleeve are sequentially fitted onto the fixing rod from the inside out. The length of the second sleeve is less than the length of the first sleeve, and the upper end of the second sleeve is flush with the upper end of the first sleeve. Evenly distributed locking strips are provided at the lower end of the second sleeve. Evenly distributed locking grooves are formed on the inner wall of the first sleeve, with the locking strips matching the grooves. Two horizontal support rods are fixedly installed on the outer wall of the first sleeve, and an installation plate is fixedly connected between the support rods. A circular groove is also formed on the inner wall of the second sleeve, and a circular airbag is glued to the inner wall of the groove. During use, the angle adjustment and fixing of the installation plate are convenient and simple, facilitating the use of the remote sensing device.

[0004] Although the ship monitoring remote sensing device mounting bracket in the aforementioned patent provides basic support for the remote sensing device through a sleeve nesting structure, and achieves horizontal angle adjustment of the mounting plate by means of the cooperation of the clips and slots, and uses airbags to enhance the connection stability between the sleeve and the fixing rod, thus providing support and initial angle adjustment for the remote sensing device, the following problems still exist: First, the height adjustment method is cumbersome and lacks a folding function. The height can only be adjusted by manually disassembling and assembling sleeves of different lengths, and cannot be dynamically adjusted in real time. Moreover, the whole structure is a single piece, which occupies a lot of space on the ship's deck when not in use, and is prone to collision with other equipment when docking or passing through narrow channels. Second, the angle adjustment and fixing efficiency is low. Horizontal angle adjustment requires manually rotating the sleeve to align with the clips, and there is no convenient angle locking structure. The angle is prone to deviation when the ship is sailing and bumpy, and pitch angle adjustment cannot be achieved. There are blind spots when facing obstacles such as high-altitude cables and shallow waters. Therefore, we propose a new type of folding obstacle avoidance observation bracket. Utility Model Content

[0005] The purpose of this invention is to solve the problems of cumbersome height adjustment, lack of folding function, low angle adjustment efficiency and blind spots in the existing ship monitoring support, and to propose a foldable obstacle avoidance observation frame.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a foldable obstacle avoidance observation frame, comprising a foldable lifting support, a rotating support fixedly connected to the top of the foldable lifting support, and an observation instrument fixedly installed on the top of the rotating support.

[0007] The folding lifting bracket includes a mounting base. The top of the mounting base has three limiting grooves arranged in a circular array. The inner surface of the limiting grooves is slidably connected to limiting sliders. The top of the limiting sliders is movably connected to folding plates. The top of the three folding plates is movably connected to a support column. The top of the support column is fixedly connected to the bottom of the rotating bracket. The bottom of the support column has a triangular groove. The inner surface of the triangular groove is slidably connected to a triangular prism. The bottom of the outer surface of the triangular prism is movably connected to three pulling plates. The end of the pulling plate away from the triangular prism is movably connected to the lower surface of the folding plate.

[0008] Preferably, the top of the support column is provided with a groove, and a first motor is fixedly connected to the inner wall of the groove. The output shaft of the first motor passes through the interior of the triangular sliding groove and is fixedly connected to a transmission screw.

[0009] Preferably, the top of the triangular prism is provided with a threaded hole, and the outer surface of the transmission screw is threadedly connected to the inner surface of the threaded hole.

[0010] Preferably, the rotating support includes a support platform, which is fixedly connected to the top of the folding lifting support. A connecting groove is provided at the center of the top of the support platform, and a rotating platform is rotatably connected inside the connecting groove. The observation instrument is fixedly installed on the top of the rotating platform.

[0011] Preferably, a second motor is fixedly connected to the rear side of the lower surface of the support platform, and the output shaft of the second motor passes through the interior of the connecting groove and is fixedly connected to a transmission wheel.

[0012] Preferably, a transmission gear ring is fixedly connected to the outer surface of the rotating platform, and the outer surface of the transmission wheel meshes with the outer surface of the transmission gear ring.

[0013] Preferably, an electric push rod is fixedly connected to the front side of the lower surface of the support platform, and a connecting slide is fixedly connected to the output end of the electric push rod.

[0014] Preferably, the top of the connecting slide plate is fixedly connected to a positioning tooth that extends through the interior of the connecting groove, and the positioning tooth slides and engages with the front side of the outer surface of the transmission gear ring.

[0015] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0016] 1. In this utility model, the electric folding adjustment of the observation height is achieved through the cooperation between the base, limiting slide, limiting slider, folding plate, support column, triangular slide, triangular prism, pulling plate, first motor, and transmission screw in the folding lifting bracket. This solves the problems of cumbersome height adjustment and lack of folding function in the prior art. This structure does not require manual disassembly and assembly of the sleeve. The height can be dynamically adjusted in real time by motor drive. It is suitable for the observation needs of obstacles at different heights such as high-altitude cables and shallow waters near the water surface, greatly improving the adjustment efficiency. Moreover, it has a folding function, which significantly reduces the volume when idle, saves the ship's deck space, and can be quickly stored when docking or passing through narrow channels to avoid collision with other equipment.

[0017] 2. In this utility model, the mutual cooperation between the support platform, rotating platform, transmission gear ring, second motor, transmission wheel, electric push rod, and positioning teeth in the rotating bracket enables convenient adjustment and stable locking of the observation angle. This structure eliminates the need for manual rotation of the sleeve to align the locking strip; the angle can be quickly adjusted by motor drive. Furthermore, the positioning teeth locking structure controlled by the electric push rod can maintain angle stability even in turbulent conditions during ship navigation, preventing angle deviation. At the same time, it can achieve omnidirectional horizontal angle adjustment. Combined with the functions of the observation instrument itself, it can eliminate the blind spots of traditional brackets, ensuring omnidirectional capture of information on obstacles in the waterway.

[0023] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] Example 1: As Figure 1 , Figure 2 and Figure 3 As shown, this utility model provides a technical solution: it includes a folding lifting bracket 1, a rotating bracket 2 fixedly connected to the top of the folding lifting bracket 1, an observation instrument 3 fixedly mounted on the top of the rotating bracket 2, the folding lifting bracket 1 includes a mounting base 11, the top of the mounting base 11 has three limiting grooves 12 arranged in a circular array, the inner surface of the limiting grooves 12 is slidably connected to limiting sliders 13, the top of the limiting sliders 13 is movably connected to folding plates 14, the top of the three folding plates 14 is movably connected to a support column 16, the top of the support column 16 is fixedly connected to the bottom of the rotating bracket 2, and the support column 16... The bottom of the device is provided with a triangular slide groove 110. A triangular prism 17 is slidably connected to the inner surface of the triangular slide groove 110. Three pull plates 15 are movably connected to the bottom of the outer surface of the triangular prism 17. The end of the pull plate 15 away from the triangular prism 17 is movably connected to the lower surface of the folding plate 14. A groove 111 is provided at the top of the support column 16. A first motor 18 is fixedly connected to the inner wall of the groove 111. The output shaft of the first motor 18 passes through the interior of the triangular slide groove 110 and is fixedly connected to a transmission screw 19. A threaded hole is provided at the top of the triangular prism 17. The outer surface of the transmission screw 19 is threadedly connected to the inner surface of the threaded hole.

[0026] The effect achieved by the entire embodiment 1 is as follows: When it is necessary to adjust the height of the observation instrument 3, the first motor 18 is started. The output shaft of the first motor 18 drives the transmission screw 19 to rotate. Since the transmission screw 19 is threadedly engaged with the threaded hole at the top of the triangular prism 17, and the triangular prism 17 is limited by the triangular slide groove 110 and cannot rotate, the rotation of the transmission screw 19 will be converted into the linear sliding of the triangular prism 17 in the triangular slide groove 110. If the triangular prism 17 slides downward, it will synchronously pull the lower surface of the corresponding folding plate 14 through the three pulling plates 15. At this time, the limiting slider 13 at the bottom of the folding plate 14 will slide towards the center in the limiting slide groove 12 of the mounting base 11, so that the three folding plates 14 slide towards the center. The folding plate 14 gradually retracts inward and the unfolding angle increases, which in turn pushes the support column 16 to lift upward, causing the rotating bracket 2 and the observation instrument 3 on top to rise. If it is necessary to lower the height, the first motor 18 is controlled to reverse, the transmission screw 19 drives the triangular prism 17 to slide upward, the pulling force of the pulling plate 15 on the folding plate 14 decreases, and the unfolding angle of the folding plate 14 decreases under the action of its own gravity and the gravity of the structure above. The limiting slider 13 slides to both ends of the limiting slide groove 12, and the support column 16 descends accordingly. When not in use, the support column 16 can be lowered to the lowest level, so that the folding plate 14 is completely retracted, which greatly reduces the overall volume of the folding lifting bracket 1, making it easy to store and not occupying too much ship deck space.

[0027] Example 2: As Figure 4 As shown, this utility model provides a technical solution: the rotating bracket 2 includes a support platform 21, which is fixedly connected to the top of the folding lifting bracket 1. A connecting groove is provided at the center of the top of the support platform 21, and a rotating platform 22 is rotatably connected inside the connecting groove. The observation instrument 3 is fixedly installed on the top of the rotating platform 22. A second motor 23 is fixedly connected to the rear side of the lower surface of the support platform 21. The output shaft of the second motor 23 passes through the interior of the connecting groove and is fixedly connected to a transmission wheel 24. A transmission gear ring 25 is fixedly connected to the outer surface of the rotating platform 22. The outer surface of the transmission wheel 24 meshes with the outer surface of the transmission gear ring 25. An electric push rod 26 is fixedly connected to the front side of the lower surface of the support platform 21. A connecting slide plate 27 is fixedly connected to the output end of the electric push rod 26. A positioning tooth 28 is fixedly connected to the top of the connecting slide plate 27 through the interior of the connecting groove. The positioning tooth 28 slides and engages with the front side of the outer surface of the transmission gear ring 25.

[0028] The overall effect of Embodiment 2 is as follows: When it is necessary to adjust the horizontal angle of the observation instrument 3, the electric push rod 26 is activated first. The output end of the electric push rod 26 pushes the connecting slide plate 27 to slide forward. The connecting slide plate 27 drives the positioning tooth 28 at the top to move synchronously, so that the positioning tooth 28 disengages from the transmission gear ring 25, releasing the angle lock on the rotating platform 22. Then, the second motor 23 is activated. The output shaft of the second motor 23 drives the transmission wheel 24 to rotate. The transmission wheel 24 drives the rotating platform 22 to rotate in the connecting groove of the support platform 21 through meshing with the transmission gear ring 25. The rotating platform 22 then drives the observation instrument 3 at the top to adjust its angle until it is aligned with the direction of the channel to be observed. After the angle adjustment is completed, the electric push rod 26 is controlled to retract. The connecting slide plate 27 drives the positioning tooth 28 to slide backward and re-engage in the tooth groove of the transmission gear ring 25, locking the rotating platform 22. Even if the ship experiences turbulence during navigation, the angle of the observation instrument 3 can be kept stable, avoiding the impact of angle deviation on obstacle identification.

[0029] The working principle of the entire device is as follows: Before use, the mounting base 11 is first fixed to the observation point at the front of the ship's bridge, the sides of the deck, or the middle of the hull with bolts. The height is adjusted according to the needs of channel observation. The first motor 18 is started, and the output shaft of the first motor 18 drives the transmission screw 19 to rotate clockwise. The transmission screw 19 drives the triangular prism 17 to slide downward along the triangular sliding groove 110 at the bottom of the support column 16 through the threaded engagement with the threaded hole at the top of the triangular prism 17. When the triangular prism 17 slides down, the three pulling plates 15 at the bottom of its outer surface pull the lower surface of the folding plate 14 downward simultaneously. At the same time, the limiting slider 13 at the bottom of the folding plate 14 is on the mounting base. The three folding plates 14 slide inward from the center within the limiting groove 12 of 11, causing them to retract inward around the movable connection point. During the retraction of the folding plates 14, the top support column 16 is pushed upward. The support column 16 drives the top rotating bracket 2 and the observation instrument 3 to rise synchronously until the required observation height is reached, at which point the first motor 18 is turned off. If it is necessary to lower the height or fold and store the plate, the first motor 18 is started to reverse, and the transmission screw 19 drives the triangular prism 17 to slide upward. The pulling force of the pulling plate 15 on the folding plate 14 is reduced, and the folding plate 14 gradually unfolds under the action of gravity. The support column 16 then descends. When it reaches the lowest point, the folding plate 14 is fully unfolded, realizing the folding of the bracket.

[0030] When the horizontal angle of the observation instrument 3 needs to be adjusted, the electric push rod 26 is activated. The output end of the electric push rod 26 pushes the connecting slide plate 27 to slide forward. The positioning teeth 28 at the top of the connecting slide plate 27 move forward synchronously, disengaging from the transmission gear ring 25 on the outer surface of the rotating platform 22, thus releasing the angle lock. Then, the second motor 23 is activated. The output shaft of the second motor 23 drives the transmission wheel 24 to rotate. The transmission wheel 24, through its meshing relationship with the transmission gear ring 25, drives the transmission gear ring 25 and the rotating platform 22 to rotate in the connecting groove of the support platform 21. The observation instrument 3 on the top of the rotating platform 22 rotates synchronously with the rotating platform 22 until the angle is adapted to the observation requirements, after which the second motor 23 is turned off. Finally, the electric push rod 26 is controlled to retract. The electric push rod 26 pulls the connecting slide plate 27 and the positioning teeth 28 to slide backward. The positioning teeth 28 re-engage in the tooth groove of the transmission gear ring 25, achieving angle fixation and ensuring that the observation instrument 3 maintains a stable viewing angle when the ship is sailing and experiencing turbulence, accurately capturing information about obstacles in the channel.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields.
