[0027] With the continuous development of my country's shipping industry, the number of ships is increasing and their functions are becoming more diversified. Most ship monitoring systems are now becoming more intelligent. However, when ships are moored, these systems cannot take close-up photos, which often leads to violent collisions, causing damage to the hull and resulting in economic losses.

[0029] Please see Figures 1 to 3 As shown, in some embodiments, this utility model provides a ship berthing safety monitoring device. The ship berthing safety monitoring device includes a monitoring box 1, a sealing door 2, a monitoring component 3, and an electric boom 4.
[0030] In some embodiments, the monitoring box 1 may be rectangular with an opening on one side. The interior of the monitoring box 1 is hollow. A mounting cavity 11 may be formed inside the monitoring box 1, which can be used to install the monitoring component 3 and the electric rod 4.
[0031] It should be noted that in some other monitoring boxes, the 1st monitoring box may also be in other shapes.
[0032] In some embodiments, a mounting block 12 is provided on the side wall edge of the monitoring box 1 away from the opening. The mounting block 12 may extend outward from the side wall edge of the monitoring box 1. A fixing hole may be provided on the mounting block 12. The ship has mounting holes corresponding to the fixing holes, and fasteners can install the monitoring box 1 on the ship through the fixing holes and mounting holes.
[0033] In some embodiments, four mounting blocks 12 may be provided. The four mounting blocks 12 may be arranged at intervals. The four mounting blocks 12 may be respectively arranged on the four perimeters of the side wall away from the opening of the monitoring box 1 to improve the stability of the installation between the monitoring box 1 and the ship.
[0034] It should be noted that in some other embodiments, there may be two, three or more mounting blocks 12.
[0035] Please see Figures 1 to 3 As shown, in some embodiments, the sealing door 2 can be rotatably hinged to the opening of the monitoring box 1. The sealing door 2 can open or close the opening of the monitoring box 1, thereby closing or opening the mounting cavity 11.
[0036] In some embodiments, a hinge 13 may be connected to the top of the monitoring box 1. The hinge 13 may be located on the edge of the top wall of the monitoring box 1 near the opening. The sealing door 2 can be rotatably connected to the monitoring box 1 via the hinge 13, thereby opening or closing the mounting cavity 11.
[0037] It should be noted that in some other embodiments, the hinge 13 may also be provided at the edge of the side wall of the monitoring box 1 near the opening or at other locations of the monitoring box 1.
[0038] In some embodiments, the hinge 13 may be a self-locking hinge. It should be noted that the hinge 13 may also adopt other hinge structures.
[0039] In some embodiments, two hinges 13 may be provided. The two hinges 13 may be arranged at intervals. The two hinges 13 may be respectively arranged on both sides of the top wall of the monitoring box 1. The sealing door 2 can be rotatably connected to the monitoring box 1 through the two hinges 13. Thus, by using two hinges 13 arranged at intervals, the stability of the rotatable connection between the sealing door 2 and the monitoring box 1 can be improved.
[0040] It should be noted that in some other embodiments, the hinge 13 may be provided in three or more parts.
[0041] Please see Figure 3 As shown, in some embodiments, the monitoring component 3 can be movably disposed within the mounting cavity 11 of the monitoring box 1. The monitoring component 3 can extend out of the mounting cavity 11 from the opening. The monitoring component 3 can be used to measure distance information between the monitoring component 3 and external objects.
[0042] In some embodiments, the electric rod 4 is telescopically disposed within the mounting cavity 11. The telescopic end of the electric rod 4 is telescopically disposed within the mounting cavity 11. The telescopic end of the electric rod 4 can be connected to the monitoring component 3. The electric rod 4 can extend towards the opening of the monitoring box 1. The electric rod 4 can shorten towards the direction away from the opening of the monitoring box 1. Specifically, when the electric rod 4 extends towards the opening of the monitoring box 1, that is, when the electric rod 4 extends towards the sealing door 2, the electric rod 4 can push the monitoring component 3 to open the sealing door 2, so that the monitoring component 3 can be exposed outside the monitoring box 1, thereby enabling the monitoring component 3 to measure the distance between the monitoring box 1 and external objects, thereby preventing collisions between the ship and external objects when the ship is anchored.
[0043] Figure 4 yes Figure 3 A schematic diagram of the middle section.
[0044] Please see Figure 3 and Figure 4 As shown, in some embodiments, the monitoring component 3 may include a movable plate 31, a first ranging sensor 32, and a second ranging sensor 33. The movable plate 31 may be plate-shaped. The movable plate 31 is movably disposed within the mounting cavity 11. The movable plate 31 can extend out of the mounting cavity 11 from an opening. Both the first ranging sensor 32 and the second ranging sensor 33 may be disposed on the movable plate 31. Thus, the first ranging sensor 32 and the second ranging sensor 33 can extend out of the mounting cavity 11 along with the movable plate 31, thereby enabling the monitoring functions of the first ranging sensor 32 and the second ranging sensor 33, and thus preventing collisions between the ship and external objects when the ship is anchored.
[0045] In some embodiments, the electric rod 4 can be connected to the movable plate 31. When the electric rod 4 extends toward the sealing door 2, it can push the movable plate 31 to move toward the sealing door 2, thereby causing the first distance sensor 32 and the second distance sensor 33 to move toward the sealing door 2. This allows the first distance sensor 32 and the second distance sensor 33 to be exposed in the mounting cavity 11, enabling them to monitor the distance between themselves and external objects.
[0046] In some embodiments, when the electric rod 4 drives the movable plate 31 to extend towards the sealing door 2, the electric rod 4 can push the movable plate 31 to overcome the gravity of the sealing door 2 and open the sealing door 2, thereby exposing the first ranging sensor 32 and the second ranging sensor 33 to the monitoring box 1. When the electric rod 4 retracts, the movable plate 31 can drive the first ranging sensor 32 and the second ranging sensor 33 to retract into the mounting cavity 11, and the sealing door 2 can close the mounting cavity 11 under the action of gravity. Thus, by using the hinge 13 on the top of the monitoring box 1, the sealing door 2 can automatically close the mounting cavity 11 under the action of gravity, improving the ease of operation of the sealing door 2.
[0047] In some embodiments, the monitoring component 3 may further include an image acquisition sensor 34. The image acquisition sensor 34 can be connected to the movable plate 31. The image acquisition sensor 34 is used to acquire image information of the exterior of the monitoring box 1. When the electric rod 4 extends toward the sealing door 2, the electric rod 4 can drive the movable plate 31 to push open the sealing door 2, allowing the image acquisition sensor 34 to be exposed in the mounting cavity 11 to acquire image information of the exterior of the monitoring box 1.
[0048] Figure 5 yes Figure 3 Cross-sectional view of monitoring box 1.
[0049] Please see Figures 3 to 5 As shown, in some embodiments, the monitoring component 3 may further include a control motherboard 35. The control motherboard 35 may be housed within the monitoring box 1. The control motherboard 35 may be electrically connected to the first ranging sensor 32, the second ranging sensor 33, and the image acquisition sensor 34. Specifically, when both the first ranging sensor 32 and the second ranging sensor 33 are exposed in the mounting cavity 11, and the image acquisition sensor 34 is also exposed in the mounting cavity 11, the control motherboard 35 can receive the distance information measured by the first ranging sensor 32 and the second ranging sensor 33, and the control motherboard 35 can receive the image information acquired by the image acquisition sensor 34. Based on the received distance and image information, the control motherboard 35 can facilitate the user in adjusting the parking direction and speed, improving the safety and accuracy of parking.
[0050] In some embodiments, a partition 36 may be provided inside the monitoring box 1. The partition 36 can divide the monitoring box 1 into a mutually separated mounting cavity 11 and a receiving cavity 14. The control main board 35 may be disposed in the receiving cavity 14.
[0051] In some embodiments, the monitoring component 3 may further include an alarm 37. The alarm 37 is connected to the outside of the monitoring box 1. The alarm 37 can be electrically connected to the main control motherboard 35. The alarm 37 can judge the distance information received by the control motherboard 35. When the distance information received by the motherboard is less than a safety threshold, the alarm can generate an alarm signal, thereby preventing the ship from colliding with external objects while anchored.
[0052] In some embodiments, the alarm signal emitted by the alarm 37 may be an alarm sound. The alarm signal emitted by the alarm 37 may be an alarm color or an alarm light.
[0053] In some embodiments, the monitoring component 3 may further include a lighting lamp 38. The lighting lamp 38 may be connected to the outside of the monitoring box 1. The lighting lamp 38 may be located on one side of the alarm 37. The lighting lamp 38 may be used to provide illumination when the device is parked, thereby preventing inaccurate information from being collected due to insufficient light from the image acquisition sensor 34. The lighting lamp 38 may also be used to illuminate the alarm information on the alarm.
[0054] Please see Figure 3 and Figure 4 As shown, in some embodiments, a groove 111 may be provided on the side wall of the mounting cavity 11. The extending direction of the groove 111 may be the same as the extension and retraction direction of the electric rod 4. The monitoring component 3 may also include a slider 311. The slider 311 may be provided on the movable plate 31. The slider 311 is movably disposed within the groove 111. When the electric rod 4 extends and pushes the movable plate 31 toward the door seal, the slider 311 can slide along the extending direction of the groove 111. When the electric rod 4 retracts and drives the movable plate 31 back into the mounting cavity 11, the slider 311 can slide along the groove 111. Thus, by using the slider 311 and the groove 111 in cooperation, the stability and accuracy of the sliding of the monitoring component 3 within the mounting cavity 11 can be improved.
[0055] In some embodiments, two slide grooves 111 may be provided. The two slide grooves 111 may be arranged at intervals. The two slide grooves 111 extend in the same direction. Two sliders 311 may be provided on the movable plate 31. The two sliders 311 and the two slide grooves 111 may be arranged in a one-to-one correspondence. Thus, by using two slide grooves 111, the stability and accuracy of the sliding of the movable plate 31 within the mounting cavity 11 can be further improved.
[0056] It should be noted that in some other embodiments, the slide 111 may have three or more slides.
[0057] Please see Figure 3 and Figure 4 As shown, in some embodiments, the monitoring component 3 may further include a connecting rod 391, a mounting plate 392, a rotating plate 393, and a motor 394. One end of the connecting rod 391 may be connected to the moving plate 31. The other end of the connecting rod 391 may be provided with the mounting plate 392. Both ends of the mounting plate 392 are provided with downwardly extending extensions, and the rotating plate 393 is rotatably disposed between the two extensions. The motor 394 may be disposed on the outer wall of the extension, and the output end of the motor 394 may be connected to the rotating plate 393 to drive rotation between the two extensions. The first ranging sensor 32 and the second ranging sensor 33 may both be connected to the rotating plate 393. The angles between the first ranging sensor 32 and the second ranging sensor 33 and the rotating plate 393 are different, so that the measurement directions of the first ranging sensor 32 and the second ranging sensor 33 are different, thereby improving the measurement range of the monitoring component 3.
[0058] In some embodiments, the first ranging sensor 32 may be arranged to extend downward perpendicularly to the rotating plate 393. The angle between the second ranging sensor 33 and the rotating plate 393 may be 30 degrees. Thus, the accuracy of distance measurement by the monitoring component 3 can be improved by using the first ranging sensor 32 and the second ranging sensor 33.
[0059] It should be noted that, in some embodiments, the included angle between the first ranging sensor 32 and the second ranging sensor 33 and the rotating plate 393 can be adjusted as needed.
[0060] Please see Figure 5 As shown, in some embodiments, the monitoring box 1 is provided with a first magnetic attractor 15, which can be located at the edge of the bottom of the monitoring box 1 near the opening. The sealing door 2 can be provided with a second magnetic attractor 21, which can be located at the end of the sealing door 2 away from the hinged end with the monitoring box 1. The first and second magnetic attractors can magnetically attract each other. When the sealing door 2 closes the opening of the monitoring box 1, the first and second magnetic attractors can be arranged facing each other and magnetically attracted together, so that the sealing door 2 and the monitoring box 1 fit tightly together.
[0061] Please see Figure 5 As shown, in some embodiments, a vacuum pump 5 may be provided inside the monitoring box 1. The vacuum pump 5 may be located inside the mounting cavity 11. The output end of the vacuum pump 5 may penetrate through the monitoring box 1. The vacuum pump 5 may be used to extract air from outside the monitoring box 1.
[0062] In some embodiments, an exhaust pipe 6 may be provided inside the monitoring box 1. A one-way valve may be provided on the exhaust pipe 6. The inlet end of the exhaust pipe 6 is connected to the mounting cavity 11, and the outlet end of the exhaust pipe 6 can be connected to the external space of the monitoring box 1 to expel air from inside the monitoring box 1. Thus, the air in the mounting cavity 11 can be replaced by the air pump 5 and the exhaust pipe 6, thereby keeping the inside of the monitoring box 1 dry, preventing air from corroding the monitoring component 3, and extending the service life of the monitoring component 3.
[0063] Figure 6 yes Figure 3 Cross-sectional view of the middle filter box 7.
[0064] Please see Figures 3 to 6 As shown, in some embodiments, a filter box 7 may be provided on the outside of the monitoring box 1. The filter box 7 may be located at the bottom of the monitoring box 1. A filter chamber 71 may be provided inside the filter box 7. A top hole 72 is provided on the side wall of the filter box 7 near the monitoring box 1. The top hole 72 may be directly connected to the output end of the air pump 5. The top hole 72 can connect the filter chamber 71 and the output end of the air pump 5. A bottom hole 73 is provided on the side wall of the filter box 7 away from the monitoring box 1. The bottom hole 73 can connect the filter chamber 71 and the external space of the filter box 7. Thus, when the air pump 5 is started, air can enter the monitoring box 1 sequentially through the bottom hole 73, the filter chamber 71, the top hole 72, and the output end of the air pump 5.
[0065] In some embodiments, a filter screen may be provided at the top hole 72. The filter screen can be used to filter the air entering the mounting cavity 11 through the filter chamber 71, thereby preventing external impurities from entering the mounting cavity 11.
[0066] In some embodiments, the filter chamber 71 may be provided with a filter sponge 74, an activated carbon layer 75, and absorbent cotton 76. The filter sponge 74, activated carbon layer 75, and absorbent cotton 76 can be arranged sequentially from the bottom hole 73 to the top hole 72. Thus, air enters through the bottom hole 73, is filtered by the filter sponge 74, activated carbon layer 75, absorbent cotton 76, and filter screen, and then enters the mounting chamber 11 through the top hole 72. At this point, the air becomes dry after filtration, thereby preventing moisture in the air from corroding the monitoring component 3 and extending the service life of the monitoring component 3.
[0067] As can be seen from the above technical solution, the embodiments of this utility model have at least the following advantages and positive effects:
[0068] This utility model provides a ship berthing monitoring device, which includes a monitoring box 1, a sealing door 2, a monitoring component 3, and an electric rod 4. The monitoring box 1 has an internal mounting cavity 11. The sealing door 2 is rotatably hinged to the opening of the monitoring box 1, used to open or close the mounting cavity 11. The monitoring component 3 is located inside the mounting cavity 11 and includes a movable plate 31 and a first distance sensor 32 and a second distance sensor 33 respectively connected to the movable plate 31. The first distance sensor 32 and the second distance sensor 33 are used to measure the distance information between themselves and external objects. The measurement direction of the first distance sensor 32 and the measurement direction of the second distance sensor 33 are set at an angle. The electric rod 4 is retractably located inside the mounting cavity 11. The electric rod 4 can push the movable plate 31 to open the sealing door 2, so that the first distance sensor 32 and the second distance sensor 33 are exposed to the monitoring box 1, thereby realizing the measurement of the distance to external objects and thus preventing collisions between the ship and external objects when the ship is berthed.
