Description

TECHNICAL FIELD

[0001] The present application relates to the ship lock navigation technology field, and particularly relates to a ship lock entrance and exit guiding device and a guiding method thereof. BACKGROUND

[0002] The ship lock is a kind of "navigation structure". In natural rivers, due to the regulation of flow, channelization navigation, and the limitation of topographic conditions and water surface slope on the canal, a stepped longitudinal section is formed to concentrate the water surface drop. Therefore, a special navigation structure is needed to enable the ship to directly pass through the drop. The most commonly used modern navigation structure is the ship lock. It is a chamber-shaped structure composed of an upper and lower entrance channel and an upper and lower entrance lock chamber. The lock chamber is a chamber-shaped room for parking ships (or fleets), which adjusts the water level in the chamber by filling or draining water to enable the ship to vertically ascend or descend between the upper and lower water levels, thereby passing through the concentrated water level drop of the channel. When the ship travels from the lower reaches to the upper reaches, the water level in the chamber is lowered to the same level as the lower reaches, and then the lower entrance lock gate is opened, the ship enters the chamber, the lock gate is closed, water is filled, and the water level is raised to the same level as the upper reaches, and then the upper entrance lock gate is opened, and the ship can exit the lock and travel to the upper reaches. When the ship travels from the upper reaches to the lower reaches, the operation procedure is reversed.

[0003] Therefore, during the ship navigation stage, the crew needs to drive the ship into the ship lock channel, which is often narrow, and multiple ships need to be driven into it, so the driving skill of the crew is extremely challenging. If the ships collide, the ship may be damaged, and the dam may be damaged.

[0031] The technical solutions of the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0032] like Figures 1-10 As shown, this is to facilitate the safe passage of ships by the operators through the lock. This invention proposes a lock entry and exit guidance device, comprising a lock channel enclosed by a lock dam body 101 and a lock gate 102, a horizontal slide rail 107 horizontally arranged on the inner wall of the lock dam body 101, a vertical lifting slide rail 116 vertically arranged on the inner wall of the lock dam body 101, a lifting traction block 129 axially slidably arranged in the lifting slide rail 116, a movable moving platform 131 placed in the lifting traction block 129, and a beam guiding component installed on the movable end of the moving platform 131 for emitting a beam of light to illuminate the water surface of the lock channel. The lifting traction block 129 is provided with a lifting ladder 167 for the horizontal movement of the moving platform 131. The lifting slide rail 116 is connected to the horizontal slide rail 107, and the moving platform 131 can slide into the horizontal slide rail 107. It also includes a water curtain component arranged on the inner wall of the lock dam body 101 for creating a bubble water curtain, the water curtain component being located below the horizontal slide rail 107.

[0033] Beam guiding components arranged on the lock dam 101 on both sides emit beams that illuminate the water surface of the lock channel. The area between the two beams is the passage zone for vessels. Vessels travel along the passage zone guided by the beams, achieving safe entry and exit from the lock. Water curtain components are arranged at the bottom of the lock dam 101, which can generate a bubble water curtain. When the beams illuminate the water surface of the lock channel, they undergo diffuse reflection, allowing the vessel operator to clearly observe the guiding beams from multiple angles. The water curtain components are arranged along the direction of the lock channel to ensure that the guiding beams can illuminate the bubble-filled water surface as the vessel moves within the lock channel.

[0034] like Figures 1-3 As shown, to achieve vertical movement of the lifting traction block 129 along the lifting slide 116, a lifting drive groove 105 is arranged parallel to the inner wall of the lifting slide 116. A lead screw 104 is vertically rotatably arranged in the lifting drive groove 105, and a lifting sleeve block 121 is axially slidably arranged in the lifting drive groove 105. The lifting sleeve block 121 is threadedly connected to the lead screw 104, and the lifting traction block 129 is fixedly connected to the lifting sleeve block 121. The two ends of the lifting traction block 129 are respectively attached to the inner walls of the lifting drive groove 105. The lifting sleeve block 121 is threadedly engaged with the lead screw 104. The lifting drive motor 103 is installed on the inner top of the lifting drive groove 105. The output shaft of the lifting drive motor 103 is coaxially fixedly connected to the top end of the lead screw 104. The lifting drive motor 103 drives the lead screw 104 to rotate, causing the lifting sleeve block 121 to move axially along the lifting drive groove 105, thereby driving the lifting traction block 129 to move axially along the lifting slide 116, so that the moving platform 131 moves in the vertical direction.

[0035] like Figure 1 , Figure 3 and Figure 7 As shown, to prevent the lifting traction block 129 in the lifting slide 116 from moving vertically after the moving platform 131 enters the horizontal slide 107, thus avoiding misalignment between the moving platform 131 and the lifting ladder 167, the inner wall of the lifting sleeve block 121 is smooth. A groove 124 is provided on the lifting sleeve block 121, and a jump block 122 that can be threadedly installed in the groove 124 and engages with the lead screw 104 is slidably mounted therein. The jump block 122 is connected to the lifting sleeve block 121 by a push spring 147. A wedge-shaped push block 123 is connected to the side wall of the jump block 122 away from the lifting sleeve block 121. The wedge-shaped push block 123 is located within the lifting ladder 167, and when the wedge-shaped push block 123 is compressed, the jump block 122 fits against the outer wall of the lead screw 104. The moving platform 131 enters the lifting channel 167. The side wall of the moving platform 131 contacts the movable end of the wedge-shaped push block 123 and presses it inward, causing the inner side wall of the wedge-shaped push block 123 to fit against the outer wall of the lead screw 104. This achieves a locking between the threads on the inner side wall of the wedge-shaped push block 123 and the threads on the outer wall of the lead screw 104. When the lead screw 104 rotates, the engagement between the wedge-shaped push block 123 and the lead screw 104 enables the lead screw 104 to drive the lifting sleeve block 121 and the lifting traction block 129 to move vertically. After the lifting traction block 129 reaches the designated position and aligns the lifting channel 167 with the horizontal slide 107, the push spring 147 relaxes when the moving platform 131 enters the horizontal slide 107, pushing the jump block 122 and the lifting sleeve block 121 to separate. Figure 3Thus, the movable end of the jumping block 122 will be tightly fitted with the inner wall of the lock dam body 101, and the outer wall of the lifting sleeve block 121 will be tightly fitted with the inner wall of the lifting drive groove 105. The lifting sleeve block 121 and the lifting traction block 129 are fixed by friction until the moving platform 131 re-enters the lifting ladder 167.

[0036] like Figure 7 As shown, to facilitate the pressing of the wedge-shaped pusher 123 by the moving platform 131, the wedge-shaped pusher 123 has an inclined surface at one end facing the outside of the lifting traction block 129, with the lower end of the inclined surface close to the horizontal slide rail 107.

[0037] like Figures 1-3 As shown, to achieve stable sliding of the mobile platform 131 within the horizontal slide 107 and the elevator 167, the top and bottom of the mobile platform 131 are provided with opening slots 133. A moving wheel 132, driven by a motor, is horizontally rotatably installed within the opening slot 133 at the bottom of the mobile platform 131. The top of the mobile platform 131 and the moving wheel 132 can respectively abut against the inner top wall and inner bottom wall of the horizontal slide 107 or the elevator 167. A motor is installed within the mobile platform 131 to drive the moving wheel 132 to rotate. The motor drives the moving wheel to roll, and the moving wheel 132 abuts against the inner bottom wall of the horizontal slide 107 or the elevator 167. When the moving wheel 132 rotates, it drives the mobile platform 131 to move stably along the horizontal slide 107 or the elevator 167. In addition, a guide pulley 141 can be horizontally rotatably installed in the opening slot 133. The guide pulley 141 located at the top of the moving platform 131 abuts against the inner top wall of the horizontal slide 107 or the lifting ladder 167. At the same time, the guide pulley 141 located at the bottom of the moving platform 131 abuts against the inner bottom wall of the horizontal slide 107 or the lifting ladder 167.

[0038] like Figure 1 and Figure 3 As shown, to prevent the mobile platform 131 from detaching from the horizontal slide rail 107 or the elevator shaft 167, the inner top of the horizontal slide rail 107 and the elevator shaft 167 are respectively provided with a horizontally oriented transverse guide groove 106 and a traction guide groove 125. When the horizontal slide rail 107 is connected to the elevator shaft 167, the transverse guide groove 106 and the traction guide groove 125 are connected. The top of the mobile platform 131 is provided with a guide block 127 that can slide within the transverse guide groove 106 and the traction guide groove 125. When the mobile platform 131 is located in the horizontal slide rail 107, the guide block 127 on the top of the mobile platform 131 is inserted into the transverse guide groove 106; when the mobile platform 131 is located in the elevator shaft 167, the guide block 127 is located within the traction guide groove 125.

[0039] like Figure 3 ,Figure 8 and Figure 10 As shown, to improve the intensity of the guiding light and achieve adjustable illumination position, the beam guiding assembly includes a guiding light source carrier 134 fixedly connected to the movable end of the moving platform 131, and a light chamber 139, a light source 135, and a lens 138 arranged within the guiding light source carrier 134. The light chamber 139 and the light source 135 are respectively arranged at one end of the guiding light source carrier 134 facing the lock channel and the other end away from the lock channel. The edge of the lens 138 is connected to the end face of a turntable 155 rotatably mounted in the light chamber 139 via a connecting block 136. The light source 135 is located above the lens 138, and the rotation axis of the light source 135, the lens 138, and the light outlet on the light chamber 139 are on an inclined straight line. The lens 138 is a unidirectional convex lens, and the light source 135 is preferably arranged at the focal point of the lens 138. Part of the light emitted by the light source 135 is refracted into parallel light rays when passing through the lens 138 and illuminates the water surface of the lock channel, thus increasing the light intensity. Figure 5 and Figure 6 As shown, when the position of the light illumination guide needs to be adjusted, the turntable 155 is driven to rotate. The turntable 155 drives the lens 138 to rotate via the connecting block 136. The lens 138 rotates in the horizontal direction, thereby changing the angle between the lens 138 and the light emitted by the light source 135. This changes the illumination position of the light refracted by the lens 138, illuminating the water surface at different locations in the lock channel, thus adjusting the position of the light illumination guide. Furthermore, the light source 135 is preferably a colored light source to facilitate observation by the ship's operator.

[0040] like Figure 8 and Figure 10 As shown, to achieve horizontal rotation of the lens 138, arc-shaped grooves 137 are provided on the opposite sidewalls of the optical chamber 139. The connecting block 136 passes through the arc-shaped grooves 137. The rotation center of the turntable 155 is coaxial with the arc-shaped grooves 137. A motor 157 for driving the turntable 155 to rotate and a drive gear 156 fixed on the output shaft of the motor 157 are installed inside the guide light source carrier 134. The edge of the turntable 155 is provided with a gear ring that meshes with the drive gear 156. The motor 157 drives the drive gear 156 to rotate through the output shaft, and the drive gear 156 drives the turntable 155 that meshes with it to rotate. The arc-shaped grooves 137 on the optical chamber 139 provide support and guidance for the turntable 155. Thus, the tooth profile of the drive gear 156 is selected as a helical gear to prevent the turntable 155 that meshes with the drive gear 156 from being displaced in the axial direction of the drive gear 156.

[0041] like Figure 4 and Figure 9As shown, to ensure that air can enter the roller body 113, the water curtain assembly includes a water curtain chamber 109 opened on the side wall of the lock dam body 101 near the lock channel. A connecting groove 111 is opened on the opposite inner wall of the water curtain chamber 109. A buoyancy carrier 112 is vertically slidably installed in the connecting groove 111. A cylindrical roller body 113 is horizontally rotatably arranged between the buoyancy carriers 112 on both sides. The roller body 113 includes a periphery of grid plates 148 and a spiral block 151 located at the axis. The grid plates 148 are distributed in a petal shape and have dense holes. The spiral block 151 is spiral in shape. Only one end of the grid plates 148 is connected to the spiral block 151 through a disc-shaped structure. The roller body 113 is supported by the buoyancy carrier 112 and floats on the water surface at the top. The mounting shaft of the roller body 113 is horizontally rotatably connected between two buoyancy carriers 112 at both ends of the water curtain chamber 109. A water curtain motor 144 is installed inside one of the buoyancy carriers 112. The output shaft of the water curtain motor 144 is coaxially and fixedly connected to one end of the mounting shaft. The roller body 113 is a horizontally arranged cylinder with an opening at one end for the spiral block 151 to push out air bubbles. In addition, to ensure that the roller body 113 is stably supported, a buoyancy balance body 114 is installed at the bottom of the buoyancy carrier 112 to increase the overall buoyancy of the buoyancy carrier 112 and the roller body 113, keeping the roller body 113 floating on the water surface of the lock channel.

[0042] The roller body 113 is supported by the buoyancy carrier 112, ensuring that a part of the roller body 113 is above the water surface. The grating plates 148 distributed in a petal shape on the edge of the roller body 113 enter the water when the roller body 113 rotates. The petal shape of the grating plates 148 pushes the air inside the grating plates 148 into the water and stirs the air to form water bubbles. The rotation of the spiral block 151 pushes the water in the roller body 113 to flow along the axial direction of the spiral block 151, and drives the water bubbles into the lock channel, forming a diffuse reflection bubble water curtain in the lock channel, which enhances the diffuse reflection intensity of the light curtain projected by the beam guiding component onto the water surface.

[0043] A guidance and prevention device for guiding ships entering and exiting a lock includes the following steps: Step 1, preparation stage: At this time, the lock channel is at a low water level. The lifting traction block 129 is controlled to descend to the bottom of the lifting slide 116, ensuring that the lifting traction block 129 does not enter the water and that the lifting slide 116 where the lifting traction block 129 is located is connected to the horizontal slide 107; Step 2, guidance stage: When ships queuing outside the lock channel are ready to enter, the light source 135 is turned on. The light source 135 illuminates the water surface above the lock channel through the lens 138. The illumination from the light sources 135 on both sides of the lock channel forms a spatial channel to guide the ships forward; Step 3, light adjustment, through... Motor 157 drives drive gear 156 to rotate, which in turn drives turntable 155 to rotate. Turntable 155 drives lens 138 to rotate through connecting block 136, changing the angle of light refracted by lens 138, thereby changing the position of light illuminating the water surface of the lock channel, and making real-time adjustments to the spatial channel guiding the ship's progress; Step 4, light following, during the ship's progress, by controlling motor to drive moving wheel 132 to rotate, the moving platform 131 in the elevator 167 slides into the horizontal slide 107, and slides forward with the ship, continuously indicating the navigation channel for the ship; Step 5, Enhanced Guidance: As the vessel begins to move forward, the water curtain assembly at the bottom of the lock dam 101 is activated. A motor drives the roller 113 to rotate, causing the grid plate 148 and the spiral block 151 to rotate, thus agitating the water surface and inducing air bubbles. The directional water flow created by the rotating spiral block 151 pushes these bubbles out from the unsealed end of the roller 113, forming a water curtain within the lock channel. This enhances the diffuse reflection intensity of the light beam and reduces refraction, thereby increasing the visibility of the light curtain. Step 6, Lifting and Protection: After the vessel enters the lock channel, the lock channel is sealed and filled with water. The control wheel 132 drives the mobile platform 131 into the lifting ladder 167. When the mobile platform 131 enters the lifting ladder 167, the side wall of the mobile platform 131 squeezes the wedge-shaped push block 123 and compresses the push spring 147, so that the thread on the side wall of the jump block 122 engages with the surface of the screw 104. At this time, the control screw 104 rotates, driving the jump block 122 to move upward, thereby pulling the lifting sleeve block 121 and the mobile platform 131 to move upward as a whole, thereby driving the guide light carrier 134 to move upward to the position where the lifting ladder 167 connects with the horizontal slide 107 on the upper part of the lock dam 101.
