Description

Technical Field

[0001] The utility model relates to the technical field of automatic alarm equipment for draft of ships passing through locks, in particular to an automatic alarm device for excessive draft of ships passing through locks. Background Art

[0002] When a ship passes through a lock, it usually goes through the pilot channel, passes the docking position, enters the cabin, goes up and down, exits the cabin, and enters the pilot channel. There are naturally requirements for the draft of the ship for safe passage on rivers, but for ships passing through the ship lift, the draft is more important because the ship has to enter the cabin. Even if the draft of the ship meets the safety requirements for passage through the river, it may not necessarily meet the safety requirements for the cabin. The cabin of the ship lift is designed with a maximum draft requirement. If a ship with a draft exceeding the limit enters the cabin, it is possible that the ship hits the bottom or even causes safety accidents such as the ship capsizing.

[0003] In the prior art, for example, the Chinese patent number CN209064325U, "Intelligent detection and alarm device for excessive draft depth of ships in ship lift navigation", respectively provides L water level followers and R water level followers at symmetrical positions on the side walls of both sides of the pilot channel. The R water level follower has the same structure as the L water level follower. The water level follower can automatically float up and down with the rise and fall of the water level. Although the utility model can automatically realize the intelligent detection of excessive draft depth and issue an alarm for the excessive object, it has a simple structure, is easy to implement, and has high working reliability, but the technology is There are still some defects when using it: First, since this technology requires the use of a large number of device components and power supply systems, the device components are prone to moisture and damage when the ship is sailing, which in turn causes failure or interruption of the power supply system, resulting in the alarm device being unable to work normally; second, the ship's draft changes briefly when passing through the lock. Since this technology lacks a device to adapt to false alarms, it is impossible to accurately judge whether the draft exceeds the safety range, such as local huge waves, etc., which in turn causes the device to give a false alarm, causing unnecessary interference and trouble.

[0015] Beneficial effects of the utility model:

[0016] 1. By setting up the alarm component and the anti-alarm component, the mechanical structure can be used to replace the traditional power system for alarm. Compared with the electrical system, the mechanical structure is more stable and reliable, and is not easily affected by factors such as power interference and failure. It can ensure the accuracy and timeliness of the alarm signal, thereby ensuring the normal navigation of the ship. When the ship is too deep, the water surface will push the airbag upward. At this time, the arc plate will slide upward, thereby prompting the raised part of the arc plate to push one end of the push rod away from the side of the positioning block. At this time, the push rod will push one end of the lever plate to move. Through the lever principle, the other end of the lever plate will move in the opposite direction. At this time, the connecting plate drives the upper block away from the lower block. At this time, the traction rope will release the limit, prompting the vortex spring to rotate with return force, and at the same time drive the wheel to rotate, thereby prompting the knocking block to continuously knock the sound disk, thereby sounding an alarm to remind the crew, thereby achieving the effect of automatic alarm, thereby avoiding the problem of easy failure when using the traditional electrical system for alarm.

[0017] 2. By setting up the anti-alarm component, the problem of false alarm caused by temporary waves, surges, etc. can be avoided, thereby ensuring the accuracy of the alarm. When a surge occurs, the wave will lift up the airbag, thereby prompting one end of the arc plate to drive the push rod to move. At this time, the lever plate will temporarily drive the upper clamping block to lift. When the wave passes, the airbag will drop again. At this time, through the action of the return spring, the push rod will move to its original position again, thereby prompting the upper clamping block to clamp the traction rope again. Therefore, through such a setting, when a surge occurs, the knocking block will only briefly or even only knock on the sound plate to sound the alarm, and the alarm will not be sounded for a long time, thereby avoiding the traditional problem of continuous alarm and false alarm.

[0027] Reference to this utility model Figures 1 to 4The device is shown as providing an automatic alarm device for excessive draft of a ship passing through a lock, comprising a first fixing plate 1, a second fixing plate 9, a third fixing plate 15 and a fourth fixing plate 29. One side of the first fixing plate 1, the second fixing plate 9 and the third fixing plate 15 are all installed on one side of the waterline of the ship. One end of the first fixing plate 1 is fixedly connected to the second fixing plate 9, and one end of the second fixing plate away from the first fixing plate 1 is fixedly connected to the third fixing plate 15. One side of the first fixing plate 1 is provided with an alarm component for automatic alarm of excessive draft of the ship, and the alarm component comprises a traction rope 19, a vortex spring 18, a knock The striking block 22 and the sound plate 33, one side of the first fixed plate 1 is fixedly connected with a placement box 27, the interior of the placement box 27 is rotatably connected with a traction roller 28, and the outside of the traction roller 28 is wound with a traction rope 19, one side of the third fixed plate 15 is rotatably connected with a rotating box 16 through an axis, the interior of the rotating box 16 is fixedly connected with a center column 17, one side of the center column 17 is fixedly connected with one end of a spiral spring 18, and the spiral spring 18 is wound around the inside of the rotating box 16, and the end of the traction rope 19 away from the traction roller 28 penetrates the side wall of the rotating box 16 and the spiral spring 18 away from the center column 17. One end is fixedly connected, the end of the center column 17 away from the rotating box 16 is fixedly connected to the rotating wheel 20, one side of the rotating wheel 20 is fixedly connected to the anti-resistance spring 21 through the connecting column, and the end of the anti-resistance spring 21 away from the rotating wheel 20 is fixedly connected to the knocking block 22, and one side of the third fixed plate 15 is also fixedly connected to the sound disk 33, and one side of the first fixed plate 1 is also provided with an anti-alarm component for avoiding false alarms, and the anti-alarm component includes an arc plate 3, an airbag 5, an upper block 13 and a lower block 12, and one side of one end of the first fixed plate 1 is fixedly connected to the side baffle 2, and one side of the side baffle 2 is provided with a slide groove The inside of the slide groove is slidably connected with an arc plate 3, the bottom of the arc plate 3 is fixedly connected with a connecting rod 4, the bottom of the connecting rod 4 is fixedly connected with an airbag 5, one side of the other end of the first fixed plate 1 is also fixedly connected with a positioning block 6, the inside of the positioning block 6 is slidably connected with a push rod 7, one side of the bottom of the second fixed plate 9 is fixedly connected with a lower clamping block 12, one side of the top of the second fixed plate 9 is connected with a connecting plate 11 through an axial rotation, the position of the upper clamping block 13 corresponds to the position of the lower clamping block 12, and the end of the traction rope 19 away from the spiral spring 18 passes through the side of the lower clamping block 12 corresponding to the upper clamping block 13.

[0028] By setting up the alarm component and the anti-alarm component, the mechanical structure can be used to replace the traditional power system for alarm. Compared with the electrical system, the mechanical structure is more stable and reliable, not easily affected by power interference, failure and other factors, and can ensure the accuracy and timeliness of the alarm signal, thereby ensuring the normal navigation of the ship. When the ship is drafted too deep, the water surface will push the airbag 5 to move upward. At this time, the arc plate 3 will slide upward, thereby prompting the raised part of the arc plate 3 to push one end of the push rod 7 away from the side of the positioning block 6. At this time, the push rod 7 will push one end of the lever plate 10 to move. Through the lever principle, the other end of the lever plate 10 will move in the opposite direction. At this time, the connecting plate 11 drives the upper block 13 away from the side of the lower block 12. At this time, the traction rope 19 will release the limit, prompting the vortex spring 18 to rotate with return force, and at the same time drive the rotating wheel 20 to rotate, thereby prompting the knocking block 22 to continuously knock the sound disk 33, thereby sounding an alarm to remind the crew, thereby achieving the effect of automatic alarm, thereby avoiding the problem of easy failure when the traditional electrical system is used for alarm.

[0029] like Figure 1 and Figure 4 As shown, a sound disk 33 is also fixedly connected to one side of the third fixed plate 15. The sound disk 33 is made of iron and has a disc-shaped shape. The knocking block 22 is made of rubber and the position of the knocking block 22 corresponds to the position of the sound disk 33. By setting the sound disk 33 to be made of iron and in a disc-shaped shape, it is eye-catching and clear, which is convenient for the operator to obtain the alarm information in time. At the same time, the anti-resistance spring 21 is set, which can prompt the knocking block 22 to continuously rotate and knock the sound disk 33, thereby playing an alarm role. At the same time, by setting the material of the knocking block 22 to be rubber, it can avoid the knocking block 22 from damaging the sound disk 33, thereby prompting the alarm device to be used for a long time.

[0030] like Figure 1 and Figure 2As shown, a fixing frame 25 is fixedly connected to one side of the bottom of the third fixing plate 15, and the fixing frame 25 is L-shaped. A second rotating column 26 is fixedly connected to one side of the fixing frame 25 away from one end of the third fixing plate 15 through an axis, and four connecting rods are fixedly connected to the outside of the second rotating column 26. A first rotating column 23 is fixedly connected to the side of the rotating wheel 20 corresponding to the second rotating column 26, and four connecting rods are fixedly connected to the outside of the first rotating column 23. One end of the four connecting rods is fixedly connected to a torsion rope 24, and one end of the torsion rope 24 away from the four connecting rods is fixedly connected to one end of the four connecting rods. Through the torsion rope 24 and the first rotating column 23, the rotating wheel 20 is fixedly connected to the first rotating column 23. The column 23 and the second rotating column 26 can prompt the knocking block 22 to knock the sound disk 33 for a long time. When in use, when the wheel 20 rotates, the first rotating column 23 will drive the connecting rod to rotate. At this time, through the action of the second rotating column 26, the four torsion ropes 24 will be entangled, thereby generating torque. At this time, when the spiral spring 18 rotates to the limit, the torsion rope 24 will use the torque to rotate in the opposite direction, thereby prompting the knocking block 22 to knock the sound disk 33 again, thereby prompting the knocking block 22 to knock the sound disk 33 for a long time, and then prompting the sound to continuously remind the crew, thereby achieving the effect of a long-term alarm.

[0031] like Figure 1 and Figure 2 As shown, the end of the traction rope 19 away from the vortex spring 18 is also fixedly connected to a rope collection roller 30, one side of the rope collection roller 30 is rotatably connected to a fourth fixing plate 29 through an axis, and the fourth fixing plate 29 is fixedly connected to the deck of the ship, and the end of the rope collection roller 30 away from the fourth fixing plate 29 is fixedly connected to a turntable 32 through an axis, and an insertion rod 31 runs through the inside of the turntable 32, and a plug hole is opened on one side of the fourth fixing plate 29, and the specification and size of the plug hole are adapted to the specification and size of the insertion rod 31. When the spiral spring 18 rotates, the traction rope 19 outside the rope collection roller 30 will be released. At the same time, when the alarm is lifted, the turntable 32 is rotated to cause the rope collection roller 30 to retract the traction rope 19, thereby causing the spiral spring 18 to generate torque again. At this time, the insertion rod 31 is inserted into the socket to fix the rope collection roller 30. Later, when the ship's draft is lifted, the upper clamping block 13 and the lower clamping block 12 clamp the traction rope 19, and then the insertion rod 31 is pulled out of the socket, thereby facilitating the next use of the alarm device.

[0032] like Figures 1 to 3As shown, the position of the airbag 5 is located on one side of the ship's draft super-deep line, and a return spring 8 is sleeved on the outside of the push rod 7. One end of the return spring 8 is fixedly connected to one side of the positioning block 6, and one end of the push rod 7 is also rotatably connected to a pulley 14 through an axis. One side of the pulley 14 contacts one side of the arc plate 3. The shape of the connecting plate 11 is semi-arc-shaped, and one end of the semi-arc connecting plate 11 is rotatably connected to the top of the upper clamping block 13 through an axis. The end of the connecting plate 11 away from the upper clamping block 13 is also rotatably connected to the lever plate 10 through an axis, and the middle part of the lever plate 10 is rotatably connected to one side of the top of the second fixed plate 9 through an axis. The end of the push rod 7 away from the pulley 14 passes through the interior of the positioning block 6 and is rotatably connected to the end of the lever plate 10 away from the connecting plate 11 through an axis. The upper clamping block 13 is fixedly connected to the side corresponding to the lower clamping block 12 with a rubber skin, and a tooth pattern is provided on one side of the rubber skin.

[0033] By setting up the anti-alarm component, the problem of false alarm caused by temporary waves, surges, etc. can be avoided, thereby ensuring the accuracy of the alarm. When a surge occurs, the wave will lift up the airbag 5, thereby prompting one end of the arc plate 3 to drive the push rod 7 to move. At this time, the lever plate 10 will temporarily drive the upper clamping block 13 to lift up. When the wave passes, the airbag 5 will drop again. At this time, through the action of the return spring 8, the push rod 7 will move to its original position again, thereby prompting the upper clamping block 13 to clamp the traction rope 19 again. Therefore, through such a setting, when a surge occurs, the knocking block 22 will only briefly or even only knock on the sound disk 33 to sound an alarm, and will not sound an alarm for a long time, thereby avoiding the traditional problem of constantly sounding an alarm and causing a false alarm. At the same time, by setting a rubber skin and providing a tooth pattern on one side of the rubber skin, the friction between the traction rope 19 and the upper clamping block 13 and the lower clamping block 12 is increased, thereby prompting the upper clamping block 13 and the lower clamping block 12 to clamp the traction rope 19, thereby avoiding the problem of rope slippage.

Under the concept of the present invention, the technical features in the above embodiments or different embodiments may be combined, the steps may be implemented in any order, and there are many other variations of the different aspects of the present invention as described above, which are not provided in detail for the sake of simplicity.
