DETAILED DESCRIPTION

[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0025] like Figure 1-6 As shown, a dock escape ladder anti-climbing device for personnel at sea includes a ladder 1, which is connected to the dock. The side end of the ladder 1 is rotatably connected to a protective plate 2, the outer surface of the protective plate 2 is smooth, and there is no fulcrum for climbing. A warning slogan can be pasted on the outer end of the protective plate 2.

[0026] A locking mechanism 3 is provided on the inner side of the protective plate 2, which can lock the protective plate 2 so that it is connected and locked together with the ladder 1. The locking mechanism 3 includes a lock shell 301. The protective plate 2 and the lock shell 301 are made of stainless steel materials with high strength and good corrosion resistance, which can effectively prevent corrosion caused by moisture on the sea surface and extend the service life of the device. A thickened plate 5 is connected to the inner side of the protective plate 2, and the lock shell 301 is connected to the side end of the thickened plate 5. The thickened plate 5 is used to connect the lock shell 301, so that the connection between it and the protective plate 2 is more firm.

The heart-shaped groove 303 includes a heart tip and a heart nest end. An insertion rod 304 is connected to one end of the movable plate 302, and a push rod 305 is connected to the other end. The insertion rod 304 and the push rod 305 are both inserted into the lock shell 301. A No. 1 spring 306 is connected between the movable plate 302 and the inner wall of the lock shell 301. The insertion rod 304 is located at the No. 1 spring 306. Inside, the side end of the push rod 305 is connected to a push plate 307, and the push plate 307 can easily drive the push rod 305 to move. An adjusting rod 308 is rotatably connected to the lock shell 301, and the adjusting rod 308 is located at the side end of the No. 1 spring 306. The side end of the adjusting rod 308 is slidably connected in the heart-shaped groove 303. The locking mechanism 3 is located at the side end of the lock block 4. The side end of the ladder 1 is connected to the lock block 4. A socket is provided in the lock block 4, and the plug rod 304 can be plugged into the socket.

[0028] The push plate 307 drives the push rod 305 to move, so that it pushes the movable plate 302 to move in the lock shell 301, thereby compressing the No. 1 spring 306 and pushing the insertion rod 304, which will enable the insertion rod 304 to be inserted into the lock block 4. At the same time, the side end of the adjusting rod 308 will move in the heart-shaped groove 303, and it will move from the heart tip to the heart socket end, and under the action of the No. 1 spring 306, it will be able to lock the movable plate 302, so that the insertion rod 304 can be locked, so that the insertion rod 304 can be inserted and fixed in the lock block 4, thereby locking the protective plate 2. When the push plate 307 is pressed again, the adjusting rod 308 will move from the heart socket end of the heart-shaped groove 303 to the heart tip, and the movable plate 302 will be able to reset under the action of the No. 1 spring 306, so that the insertion rod 304 can leave the lock block 4, thereby releasing the lock on the protective plate 2, and the protective plate 2 can be opened at this time.

[0029] A baffle 201 is connected between the ladder 1 and the dock wall, a side sealing plate 202 is connected to the side end of the protective plate 2, the side sealing plate 202 is located at the side end of the locking block 4, and a lower sealing plate 203 is connected to the lower end of the protective plate 2. The lower sealing plate 203 can fit with the ladder 1. The baffle 201, the side sealing plate 202, and the lower sealing plate 203 are used to close the gap between the protective plate 2 and the ladder 1, thereby preventing illegal elements from using tools to open the locking mechanism 3.

[0030] A rectangular groove 6 is provided at the upper end of the protective plate 2, and a detection rod 7 is slidably connected in the rectangular groove 6. A No. 2 spring 8 is connected between the detection rod 7 and the rectangular groove 6. A pressure block 9 is connected to the lower end of the detection rod 7. A button 10 is connected in the rectangular groove 6, and the button 10 can be connected to the pressure block 9. A data box 11 is connected to the inner side of the protective plate 2. A controller, a buzzer, and a battery block are provided in the data box 11. The data box 11 and the button 10 are connected by a wire. When the detection rod 7 is pressed and moved downward, the No. 2 spring 8 will be compressed, which can make the pressure block 9 and the button 10 act. The pressure of the button 10 will trigger the data box 11, and the controller in the data box 11 will send an alarm message to the remote control end, and the buzzer will directly alarm.
