Description

Technical Field

[0001] This utility model relates to the field of ship-bridge safety distance monitoring technology, and more specifically, to a ship-bridge safety distance monitoring and alarm device. Background Technology

[0002] Ship-bridge safety distance monitoring refers to the real-time detection, analysis, and determination of the spatial relationship between ships and bridges using laser rangefinders. This not only significantly reduces the incidence of ship-bridge collision accidents but also improves waterway traffic efficiency, providing a solid guarantee for maritime traffic safety.

[0003] A search revealed that Chinese patent CN221024111U discloses a ship distance monitoring and early warning device. By extending an arm, the off-axis ranging device is moved as far away from the central ranging device as possible. The off-axis ranging device and the central ranging device work together to form a ranging surface parallel to the deck, thereby avoiding ranging errors.

[0004] When the aforementioned monitoring and early warning device is in use, it uses a central ranging device and two off-axis ranging devices to measure the distance to the bridge in front of the ship. However, it can only monitor the front of the ship and it is inconvenient to adjust the angle of the ranging device. As a result, it is difficult to accurately target key lateral risk points such as bridge piers and anti-collision piers on both sides of the bridge, which can easily lead to missed reports of lateral collision risks. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a ship-bridge safety distance monitoring and alarm device, which aims to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a ship-bridge safety distance monitoring and alarm device, comprising a mounting box, a first distance measuring instrument body and multiple second distance measuring instrument bodies, wherein the first distance measuring instrument body is fixedly installed at the front center position of the mounting box, and the first distance measuring instrument body and multiple second distance measuring instrument bodies are used to monitor the distance between the ship and the bridge, and the bottom of the mounting box is provided with an adjustment component for adjusting the position of the first distance measuring instrument body and multiple second distance measuring instrument bodies; The adjustment assembly includes a column, a connecting cylinder, a hydraulic cylinder, a first stepper motor, a first conductive plate, and multiple second conductive plates. The column is fixedly installed at the center of the bottom end of the mounting box, and the column and the top end of the connecting cylinder are movably connected by a bearing. One side of the first conductive plate is fixedly connected to the column, and the bottom ends of the multiple second conductive plates are fixedly connected to the connecting cylinder. The controller body, alarm and multiple warning lights are fixedly installed on the rear side of the mounting box.

[0007] Furthermore, the first stepper motor is fixedly installed at the bottom of the inner end of the connecting cylinder, and the output shaft end of the first stepper motor is fixedly connected to the column.

[0008] Furthermore, the output shaft of the hydraulic cylinder is fixedly connected to the connecting cylinder, and a fixing plate is fixedly connected to the bottom end of the hydraulic cylinder.

[0009] Furthermore, a camera is fixedly installed at the top center of the mounting box, and a rain shield is provided on the top of the camera to protect the camera and the controller body from rain, and the bottom end of the rain shield is fixedly connected to the mounting box.

[0010] As can be seen, the above technical solution uses cameras to perform real-time visual monitoring of the bridge structure and waterway environment, assisting drivers in confirming the validity of the distance measurement data.

[0011] Furthermore, a U-shaped plate is fixedly connected inside the mounting box. The U-shaped plate is equipped with a moving component for adjusting the position of multiple second rangefinder bodies. The moving component includes a positive and negative lead screw, two sliding plates, two L-shaped plates, a bevel gear set, and a second stepper motor.

[0012] Furthermore, the positive and negative lead screws are movably connected to both sides of the U-shaped plate via bearings, both slide plates are threaded to the outer side of the positive and negative lead screws, and the opposite sides of the two slide plates are respectively fixedly connected to two L-shaped plates. The front side and one side of the two L-shaped plates are respectively fixedly connected to multiple second rangefinder bodies.

[0013] Furthermore, the second stepper motor is fixedly installed at the bottom end of the U-shaped plate, and the second stepper motor is connected to the forward and reverse lead screws through a bevel gear set.

[0014] It can be seen that the above technical solution is designed to facilitate the rotation of the forward and reverse lead screws.

[0015] Furthermore, each of the two slide plates is movably fitted with a side frame, and the opposite side of each side frame is fixedly connected to the mounting box.

[0016] As can be seen, in the above technical solution, the side frame can prevent the slide from detaching from the positive and negative lead screws.

[0017] The technical effects and advantages of this utility model are as follows: 1. In this utility model, when the ranging data received by the controller body is lower than the preset safety threshold, the alarm is immediately triggered to emit a high-decibel warning sound. The hydraulic cylinder works to drive the first rangefinder body and the four second rangefinder bodies to move upward. The first stepper motor works to drive the mounting box, the first rangefinder body and the four second rangefinder bodies to rotate. The operation is simple and the angle of the ranging device can be easily adjusted. 2. This utility model uses a second stepper motor to drive the forward and reverse lead screws through a bevel gear set. The forward and reverse lead screws can drive two sliding plates and two L-shaped plates to move in opposite directions. The positions of multiple second rangefinder bodies can be adjusted as needed. When the waterway is wide or the distance between bridge piers is large, the two second rangefinder bodies are controlled to move in opposite directions to expand the monitoring coverage. When the waterway is narrow, they are moved relative to each other to focus on key areas, effectively avoiding monitoring blind spots caused by unreasonable distribution of ranging points. The structure is simple and easy to use. Attached Figure Description

Detailed Implementation

[0021] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] Example 1 Refer to the instruction manual appendix Figure 1-5 The embodiment of the ship-bridge safety distance monitoring and alarm device includes a mounting box 1, a first distance measuring instrument body 2 and a plurality of second distance measuring instrument bodies 3. The first distance measuring instrument body 2 is fixedly installed at the front center position of the mounting box 1. The first distance measuring instrument body 2 and the plurality of second distance measuring instrument bodies 3 are used to monitor the distance between the ship and the bridge. The bottom of the mounting box 1 is provided with an adjustment component 5 for adjusting the position of the first distance measuring instrument body 2 and the plurality of second distance measuring instrument bodies 3. The adjustment assembly 5 includes a column 501, a connecting cylinder 502, a hydraulic cylinder 503, a first stepper motor 504, a first conductive plate 505, and multiple second conductive plates 506. The column 501 is fixedly installed at the center of the bottom end of the mounting box 1, and the column 501 and the top end of the connecting cylinder 502 are movably connected by a bearing. One side of the first conductive plate 505 is fixedly connected to the column 501, and the bottom ends of the multiple second conductive plates 506 are fixedly connected to the connecting cylinder 502. The controller body 10, the alarm 11 and multiple warning lights 12 are fixedly installed on the rear side of the mounting box 1.

[0023] Refer to the instruction manual appendix Figure 1 , 2 5. The first stepper motor 504 is fixedly installed inside the bottom of the connecting cylinder 502, and the output shaft end of the first stepper motor 504 is fixedly connected to the column 501. The output shaft of the hydraulic cylinder 503 is fixedly connected to the connecting cylinder 502, and the bottom end of the hydraulic cylinder 503 is fixedly connected to the fixing plate 4.

[0024] Refer to the instruction manual appendix Figure 1-3 A camera 8 is fixedly installed at the top center of the mounting box 1. A rain shield 9 is provided on the top of the camera 8 to protect the camera 8 and the controller body 10 from rain, and the bottom end of the rain shield 9 is fixedly connected to the mounting box 1.

[0025] The usage method of this embodiment is as follows: In use, the fixing plate 4 is installed at the preset installation position on the bow or deck of the ship by multiple bolts and washers. The first distance measuring instrument body 2 and the second distance measuring instrument body 3 on the front side of the two L-shaped plates 603 cooperate to form a multi-point distance measuring matrix in front, which accurately captures the real-time distance data between the ship and the main body of the bridge. When the distance measuring data received by the controller body 10 is lower than the preset safety threshold, the alarm 11 is immediately triggered to emit a high-decibel warning sound. When the ship enters the navigation area at the bottom of the bridge, the distance between the ship and the two sides inside the bridge is monitored by the second distance measuring instrument body 3 on the opposite side of the two L-shaped plates 603. Start the hydraulic cylinder 503. The hydraulic cylinder 503 works to drive the connecting cylinder 502 to move upward, thereby driving the first rangefinder body 2 and the four second rangefinder bodies 3 to move upward. Adjust the height of the first rangefinder body 2 and the four second rangefinder bodies 3 as needed. Start the first stepper motor 504. The first stepper motor 504 drives the column 501 to rotate, which in turn drives the mounting box 1, the first rangefinder body 2 and the four second rangefinder bodies 3 to rotate. Adjust the angle of the first rangefinder body 2 and the four second rangefinder bodies 3 as needed. It can accurately align with the bridge piers, anti-collision piers and other key lateral risk points on both sides of the bridge, and completely solve the problem of missed reporting caused by the fixed angle of traditional devices. When the column 501 rotates, it synchronously drives the first conductive plate 505 to rotate. When the first conductive plate 505 contacts one of the second conductive plates 506, the warning light 12 at the corresponding position lights up red, providing real-time feedback on the angle adjustment status and helping the driver confirm the alignment area of ​​the ranging device. The operation is simple and the angle of the ranging device can be easily adjusted. At the same time, the camera 8 can also perform real-time visual monitoring of the bridge structure and waterway environment, assisting the driver in confirming the validity of the ranging data. It is worth noting that the main body 2 of the first ranging device and the four L-shaped plates 603 are all laser ranging devices, which have the advantages of high ranging accuracy and fast response speed.

[0026] Example 2 Refer to the instruction manual appendix Figure 1-4 Based on Embodiment 1, this utility model provides a bridge safety distance monitoring and alarm device: a U-shaped plate 13 is fixedly connected inside the mounting box 1, and a moving component 6 for adjusting the position of multiple second rangefinder bodies 3 is provided on the U-shaped plate 13. The moving component 6 includes a positive and negative lead screw 601, two sliding plates 602, two L-shaped plates 603, a bevel gear set 604, and a second stepper motor 605.

[0027] The positive and negative lead screws 601 are movably connected to both sides of the U-shaped plate 13 via bearings. The two slide plates 602 are threaded to the outer side of the positive and negative lead screws 601, and the opposite sides of the two slide plates 602 are fixedly connected to the two L-shaped plates 603 respectively. The front side and one side of the two L-shaped plates 603 are fixedly connected to multiple second rangefinder bodies 3 respectively. The second stepper motor 605 is fixedly installed at the bottom end of the U-shaped plate 13, and the second stepper motor 605 is connected to the positive and negative lead screws 601 via a bevel gear set 604.

[0028] Furthermore, side frames 7 are movably fitted on both slide plates 602, and the opposite sides of the two side frames 7 are fixedly connected to the mounting box 1.

[0029] The usage method of this embodiment is as follows: When the second stepper motor 605 is started, since the bevel gear set 604 includes two bevel gears, and the two bevel gears are fixedly connected to the output shaft end of the second stepper motor 605 and the positive and negative lead screw 601 respectively, the second stepper motor 605 can drive the positive and negative lead screw 601 to rotate through the bevel gear set 604. Since the two slide plates 602 are threadedly connected to the positive and negative lead screw 601, and the mounting box 1 restricts the rotation of the two slide plates 602, the positive and negative lead screw 601 can drive the two slide plates 602 and the two L-shaped plates 603 to move in opposite directions. The positions of multiple second rangefinder bodies 3 can be adjusted as needed. When the waterway is wide or the distance between bridge piers is large, the two second rangefinder bodies 3 are controlled to move in opposite directions to expand the monitoring coverage. When the waterway is narrow, they are moved relative to each other to focus on key areas, effectively avoiding monitoring blind spots caused by unreasonable distribution of ranging points. The structure is simple and easy to use. At the same time, the side frame 7 can prevent the slide plates 602 from disengaging from the positive and negative lead screw 601.

Electrical control components not mentioned in this technical solution are not shown in the figures because they are existing technologies, and will not be described here.

[0031] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
