Technical Field

[0001] The utility model relates to the technical field of anti-collision devices for ship lifts, in particular to a dynamic distance display device between a ship and an anti-collision device. Background Art

[0002] The efficient and safe operation of the ship lift depends on the establishment and improvement of ship passing safety detection technology and equipment. Among them, the real-time detection and dynamic display of the ship's speed in the cabin and the distance between the ship and the anti-collision device is a key technology and a weak link. Although a set of anti-collision devices are arranged on the upper and lower cabins of the ship lift, in order to reduce the risk of collision between the ship entering the cabin and the cabin door, improve the efficiency of ship passing, and ensure the safety of the ship and the ship lift, it is urgent to detect the position of the ship in the cabin, especially the position information in the warning area. Therefore, it is very necessary to measure and dynamically display the speed and position of the ship passing the elevator in the cabin, and to give warnings according to the relevant ship lift operation procedures. Summary of the invention

[0005] Preferably, a mounting frame is fixedly provided at the tail end of the ship lift, a laser light is fixedly provided on the mounting frame, the laser light is arranged obliquely downward, and the light mark point is the intersection of the light of the laser light and the water surface of the channel.

[0006] Preferably, the laser lights are located on both sides of the waterway, and the laser lights on both sides are arranged in a mirror-symmetrical manner along the waterway, and the laser intersection points of the laser lights on both sides are located at the light mark points.

[0008] Preferably, a laser rangefinder is provided on the bracket, and the laser rangefinder is arranged perpendicular to the waterway.

[0009] Preferably, a gushing pipe is fixedly provided at the edge of the channel, and the gushing pipe is arranged toward the light marking point.

[0010] The utility model provides a dynamic distance display device between a ship and an anti-collision device. By means of equidistantly arranged infrared sensors, when a ship intercepts an infrared signal when passing, the ship's speed is judged according to the time difference of the intercepted signals of adjacent infrared sensors, the position deviation of the ship relative to the center of the channel is judged through light marking points, and the distance of the ship relative to the rear end of the ship passing machine is judged through the light marking points, so as to achieve the effect of anti-collision warning. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0012] Figure 1 It is a schematic structural diagram of an embodiment of the utility model.

[0013] In the figure: 1. Infrared transmitter; 2. Infrared receiver; 3. Laser rangefinder; 4. Mounting bracket; 5. Laser light; 6. Mark three; 7. Mark two; 8. Mark one; 9. Geyser pipe. DETAILED DESCRIPTION

[0014] like Figure 1 As shown, the utility model proposes a dynamic distance display device between a ship and an anti-collision device, comprising brackets radially symmetrically arranged on both sides of the channel of the ship lift, the brackets are equidistantly arranged along the direction of the channel, an infrared transmitter 1 is installed on the bracket on one side of the channel, an infrared receiver 2 is installed on the bracket on the other side of the channel, a light marking point is arranged at the tail section of the ship lift channel, the light marking point is located on the center line of the ship lift channel, and a camera facing the light marking point is arranged at the tail end of the ship lift.

[0015] The infrared transmitters 1 and infrared receivers 2 on both sides of the channel are arranged in a one-to-one correspondence. During the navigation of the ship, when the ship passes through a group of infrared transmitters 1 and infrared receivers 2, the signal of the infrared receiver 2 will be intercepted, and the infrared receiver 2 will send the signal that has not received the infrared light to the control center. When the ship intercepts the next group of infrared transmitters 1 and infrared receivers 2, the speed of the ship can be calculated according to the time difference of the control center receiving the signal and the distance between adjacent brackets, and the position information of the ship can be directly obtained. Subsequently, the ship is guided through the light marking points, and the ship is controlled to make corresponding deceleration adjustments according to the measured ship speed to avoid collision during the movement of the ship.

[0016] like Figure 1As shown, in order to realize the setting of the light mark point, the tail end of the ship lift is fixedly provided with a mounting frame 4, on which a laser light 5 is fixedly provided, and the laser light 5 is arranged obliquely downward, and the light mark point is the intersection of the light of the laser light 5 and the water surface of the channel.

[0017] By arranging the laser lights 5 obliquely, light marking points are formed on the water surface of the channel, and the light marking points are used as guides for the navigation of the ship.

[0018] like Figure 1 As shown, in order to improve the brightness of the light mark point, the laser lights 5 are located on both sides of the channel, and the laser lights 5 on both sides are arranged symmetrically along the channel, and the laser intersection of the laser lights 5 on both sides is located at the light mark point. Compared with the water surface of the channel, the light of the two laser lights 5 improves the brightness of the light mark point to achieve ship navigation guidance.

[0019] like Figure 1 The light marking points are sequentially arranged with a punctuation point 1 8, a punctuation point 2 7 and a punctuation point 3 6 along the navigation direction of the ship, and the gap between the punctuation point 1 8 and the punctuation point 2 7 is larger than the gap between the punctuation point 2 7 and the punctuation point 3 6.

[0020] When the ship reaches punctuation 1 (8), the ship is notified to slow down. When the ship reaches punctuation 2 (7), the ship needs to stop sailing. If the ship still has a certain speed when it reaches punctuation 2 (7), it needs to stop immediately.

[0021] like Figure 1 As shown. The bracket is provided with a laser rangefinder 3, which is arranged perpendicular to the channel. The laser rangefinder 3 is used to detect the distance between the ship in the channel and the edge of the channel of the ship lift to ensure that the ship moves in the middle of the channel. At the same time, multiple laser rangefinders 3 can determine whether the ship is parallel to the channel.

[0022] like Figure 1 As shown. A gushing pipe 9 is fixedly arranged at the edge of the waterway, and the gushing pipe 9 is arranged toward the light mark point. Water is sprayed toward the light mark point through the gushing pipe 9, so that the light mark point is in a surge state, avoiding mirror reflection at the light mark point, so as to form a diffuse reflection method, thereby improving the convenience of obtaining the light mark point.
