Description

Technical Field

[0001] This utility model relates to an alarm device for a single-person bridge on a ship, and particularly to an alarm device for a single-person bridge on a ship applied in the field of ship alarms. Background Technology

[0002] "One-person bridge" is not a standard ship structural term. It usually refers to the bridge or wheelhouse on modern, highly automated ships. "Bridge" refers to the bridge area of ​​the ship, while "one-person" emphasizes the core concept of modern ship bridge design: through high automation and system integration, only one qualified driver (usually the watch officer) is needed to safely and effectively operate and monitor the ship's main navigation systems under normal navigation conditions.

[0003] During ship navigation, in accordance with the mandatory requirements of international conventions and industry standards, it is necessary to arrange for officers to be on watch at night. However, when officers are on watch at night, they are prone to fatigue due to reasons such as disruption of their biological clock or environmental influences, which may lead to accidents.

[0004] The specification of Chinese Patent Publication No. CN208498477U discloses a driver fatigue warning device. This utility model judges the driver through multiple judgment methods. After judging that the driver is in a fatigued state, it will give an alarm through an alarm and an alarm light. However, in the case of severe fatigue, the sound and light effect alone is very weak, which has certain safety hazards. Utility Model Content

[0005] The technical problem that this utility model aims to solve in view of the above-mentioned prior art is that drivers on night shifts are prone to fatigue, which can lead to safety accidents. Most current alarm devices alert drivers through alarms or warning lights, which are of little effect and pose certain safety hazards.

[0006] To address the aforementioned problems, this utility model provides an alarm device for a single-person bridge on a ship, including a seat. The upper end of the seat has a mounting groove. Multiple support rods are fixedly connected to the inner bottom wall of the mounting groove. Elastic blocks are fixedly connected to the upper ends of the support rods. Two mounting plates are fixedly connected to the upper ends of the multiple elastic blocks, and a low-frequency vibration motor is fixedly connected to the lower end of each mounting plate. A secondary warning component is fixedly embedded in the upper end of the seat, located behind the mounting groove. A seat cushion is also fixedly connected to the upper end of the seat, and armrests are fixedly connected to both the left and right ends of the seat, one of which... A button is fixedly connected to the inner top wall of the seat. The secondary warning component includes a housing box fixedly embedded in the upper part of the seat. A positioning plate is fixedly connected to the inner cavity of the housing box. Multiple mounting blocks are fixedly connected to the lower end of the positioning plate. A tension spring is fixedly connected to the inner bottom wall of the mounting block. A top block is fixedly connected to the upper end of the tension spring. A top rod is fixedly connected to the lower end of the top block. The lower end of the top rod moves through the tension spring and the mounting block. A baffle is fixedly sleeved on the outer surface of the top block. An adjustment motor is fixedly connected to the front end of the housing box. A screw is fixedly connected to the output end of the adjustment motor. A push block is threaded on the outer surface of the screw.

[0007] In the aforementioned alarm device for a single-person bridge on a ship, a dual alarm structure is formed by a low-frequency vibration motor and a secondary warning component. When the driver shows signs of fatigue through an external monitoring component, the low-frequency vibration motor first causes the seat to vibrate, thus gently alerting the driver. The driver can confirm wakefulness by pressing a button. If the driver does not confirm wakefulness within a certain period of time, the secondary warning component can physically push the seat cushion for forced intervention. Compared with existing alarm devices that only provide sound and light alerts, this application effectively improves the fatigue alarm effect by stimulating the driver through tactile stimulation, thereby effectively reducing the occurrence of safety accidents.

[0008] As a further improvement of this application, the longitudinal section of the push block is triangular, and the upper end of the push block is treated with an arc surface, while the lower end of the push rod is treated with a round head.

[0009] As a further improvement of this application, the front end of the push block is movable through two limiting rods, the front and rear ends of the limiting rods are fixedly connected to the front and rear inner walls of the receiving box respectively, and the screw is located between the two limiting rods.

[0010] As a further improvement of this application, the upper end of the top block movably passes through the mounting block and contacts the lower end of the seat cushion, the lower end of the baffle is attached to the upper end of the positioning plate, and a pad is fixedly connected to the front of the upper end of the positioning plate. The upper end of the pad is attached to the lower end of the seat cushion, and the seat cushion is made of flexible material.

[0011] As another improvement of this application, the longitudinal section of the handrail is U-shaped, the button is located at the rear of the inner top wall of the handrail, and the low-frequency vibration motor, the adjustment motor and the button are all connected to the signal of the external controller.

[0012] As another improvement of this application, an audible and visual alarm is fixedly connected to the upper end of one of the handrails, and the audible and visual alarm is connected to an external controller.

[0013] In summary, in practical applications, the driver is monitored by an external monitoring agency. When the driver is fatigued, a low-frequency vibration motor is activated to cause the seat to vibrate, resulting in vibration of the driver's legs and providing a gentle alarm. Once the driver is awake, they can press a button to confirm wakefulness, causing the low-frequency vibration motor to stop vibrating. If the driver does not press the button to confirm wakefulness within a certain time, an adjusting motor is activated to rotate the screw, causing the push block to move backward, which in turn pushes the top rod upward, causing the top block to move upward and physically push the seat cushion. This creates a wave-like undulation of the multiple rows of top blocks, lifting the driver's buttocks and changing their sitting posture, thus forcibly waking the driver. Compared to existing alarm devices that only rely on sound and light, this application uses tactile stimulation to effectively improve the fatigue alarm effect and reduce the occurrence of safety accidents.

Detailed Implementation

[0025] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0026] First implementation method:

[0027] Figure 1 , Figure 2 , Figure 3 and Figure 4 The diagram illustrates an alarm device for a single-person bridge on a ship, comprising a seat 1. The upper end of the seat 1 has a mounting groove 2 for mounting a low-frequency vibration motor 6. Multiple support rods 3 are fixedly connected to the inner bottom wall of the mounting groove 2 on the front side. Elastic blocks 4 are fixedly connected to the upper ends of the support rods 3, transmitting the vibrations generated by the low-frequency vibration motor 6. Two mounting plates 5 are fixedly connected to the upper ends of the multiple elastic blocks 4, and the low-frequency vibration motor 6 is fixedly connected to the lower ends of the mounting plates 5. Those skilled in the art can select a suitable model of low-frequency vibration motor 6 according to actual needs, such as Yzo-20-6. The low-frequency vibration of the low-frequency vibration motor 6 matches the frequency of human tactile sensitivity, avoiding high-frequency discomfort. A secondary warning component is fixedly embedded in the upper end of the seat 1, located behind the mounting groove 2. The upper end of the seat 1 is also fixedly connected to... The seat cushion 7 is made of flexible material. The seat cushion 7 not only improves the driver's riding comfort, but also deforms as the top block 14 is raised. Both ends of the seat 1 are fixedly connected to armrests 8. A button 9 is fixedly connected to the inner top wall of one of the armrests 8. Those skilled in the art can select a suitable model of button 9 according to actual needs, such as SQB. The longitudinal section of the armrest 8 is U-shaped. The button 9 is located at the rear of the inner top wall of the armrest 8. The position of the button 9 can not only effectively avoid accidental triggering, but also prevent the driver from pressing it casually. When the driver is awake, he needs to make a larger movement to search, which can effectively accelerate the driver's awakening. The low-frequency vibration motor 6, the adjustment motor 17 and the button 9 are all connected to an external controller signal. Those skilled in the art can select a suitable model of controller according to actual needs, such as OHR-B300A-A.

[0028] Figure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 7 and Figure 8 The secondary warning assembly includes a housing 10 fixedly embedded in the upper part of the seat 1. A positioning plate 11 is fixedly connected to the inner cavity of the housing 10. Multiple mounting blocks 12 are fixedly connected to the lower end of the positioning plate 11. A tension spring 13 is fixedly connected to the inner bottom wall of the mounting block 12. A top block 14 is fixedly connected to the upper end of the tension spring 13. A top rod 15 is fixedly connected to the lower end of the top block 14. The lower end of the top rod 15 is rounded. The lower end of the top rod 15 movably passes through the tension spring 13 and the mounting block 12. The outer surface of the top block 14 is fixed. A baffle 16 is fitted onto the housing 10, and an adjusting motor 17 is fixedly connected to the front end of the housing 10. Those skilled in the art can select a suitable model of adjusting motor 17 according to actual needs, such as Y2-63M1-2-0.18KW. A screw 18 is fixedly connected to the output end of the adjusting motor 17. A push block 19 is threaded onto the outer surface of the screw 18. The longitudinal section of the push block 19 is triangular, and the upper end of the push block 19 is arc-shaped. Two limiting rods 20 movably pass through the front end of the push block 19. The front and rear ends of the limiting rods 20 are... The screw 18 is fixedly connected to the front and rear inner walls of the receiving box 10. The screw 18 is located between the two limiting rods 20. The limiting rods 20 can limit the push block 19, forcing the push block 19 to move only back and forth. The upper end of the top block 14 moves through the mounting block 12 and contacts the lower end of the seat cushion 7. The lower end of the baffle 16 is attached to the upper end of the positioning plate 11. The adjustment motor 17 is started to drive the screw 18 to rotate, causing the push block 19 to move backward. As the push block 19 moves, the push block 19 contacts the lower end of the top rod 15. The top rod 15 moves along the push block. The slope of 19 moves upward, thereby pushing the push rod 15 upward. At this time, the tension spring 13 is stretched upward, and the push block 14 moves upward, physically pushing the seat cushion 7, so that the multiple rows of push blocks 14 undulate in a wave-like manner, thereby lifting the driver's buttocks and forcibly waking the driver. The upper front part of the positioning plate 11 is also fixedly connected to the pad 21. The upper end of the pad 21 fits against the lower end of the seat cushion 7. The pad 21 fills the gap between the positioning plate 11 and the seat cushion 7, thereby effectively improving the driver's riding comfort.

[0029] When the driver is on night duty, sitting in seat 1, the driver is monitored by an external monitoring device, such as a heart rate monitoring wristband or camera. When the monitoring device detects that the driver is fatigued, it first activates the low-frequency vibration motor 6 to cause the seat 1 to vibrate, causing the driver's legs to vibrate, thus gently alerting the driver. After the driver regains consciousness, they can press button 9 to confirm wakefulness, causing the low-frequency vibration motor 6 to stop vibrating. If the driver does not press button 9 to confirm wakefulness within a certain period of time, the adjusting motor 17 is activated to drive the screw 18 to rotate, causing the push block 19 to move backward, thereby pushing the top rod 15 upward, causing the top block 14 to move upward, physically pushing the seat cushion 7, causing the multiple rows of top blocks 14 to undulate in a wave-like manner, thus lifting the driver's buttocks and forcibly waking the driver. Compared with existing alarm devices that only rely on sound and light to alert the driver, this application uses tactile stimulation to effectively improve the fatigue alarm effect and effectively reduce the occurrence of safety accidents.

[0030] Second implementation method:

[0031] This embodiment adds an audible and visual alarm 22 to the first embodiment, while the rest remains the same as the first embodiment.

[0032] Figure 9 As shown: an audible and visual alarm 22 is fixedly connected to the upper end of one of the handrails 8, and the audible and visual alarm 22 is connected to an external controller.

[0033] If the driver still does not press button 9 to confirm wakefulness after the secondary warning component has been activated for a certain period of time, the audible and visual alarm 22 will emit sound and light to prompt the night shift personnel to check the driver's physical condition and determine whether the driver has fainted due to physical reasons.

[0034] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this utility model.
