Description

Technical Field

[0001] This invention relates to the field of waterway warning technology, and in particular to a navigation warning device for basic waterways used in port logistics. Background Technology

[0002] The port logistics basic waterway is a key channel for ships to enter and leave the port. Its navigation warning device plays a vital role in ensuring the safety of ship navigation. The navigation warning device is usually in the form of a buoy, which is fixed to a designated position in the waterway by an anchor chain. The buoy is equipped with a light frame and a warning light, which emits navigation warning light signals at night or when visibility is low to guide ships to pass safely.

[0003] However, the hydrological environment in port waters is complex. Under the combined effects of waves, swells, ship wakes, and severe weather, buoys can experience violent shaking and tilting, and may even capsize under the impact of strong waves. When a buoy tilts, the warning light will also tilt. In strong wave conditions, the buoy can only rely on buoyancy to reset itself, which makes it difficult for the warning light to reset and causes it to tilt continuously due to severe weather. As a result, the luminous surface of the warning light is blocked by the waves or deviates from the ship's driver's line of sight, causing a significant reduction in the warning effect. Summary of the Invention

[0004] In order to overcome the shortcomings pointed out in the background art above, the present invention provides a navigation warning device for port logistics basic waterways.

[0005] Technical Solution: A navigation and warning device for basic waterways in port logistics includes a buoy, a light frame mounted on the buoy, a connecting frame mounted on the light frame, a warning light mounted on the light frame, symmetrically distributed guide rods fixed to the connecting frame, symmetrically distributed rotating rods rotatably connected to the connecting frame, a sliding frame slidably connected to all the guide rods, the rotating rods being threadedly connected to the sliding frame, a plurality of circumferentially evenly distributed support rods rotatably connected to the connecting frame, the sliding frame being used to compress all the support rods, a support plate being rotatably and sealingly connected to the support rods, and a torsion spring being fixedly connected between the support plate and the adjacent support rod.

[0006] Preferably, the width of the support plate gradually decreases from the distance away from the central axis of the lamp holder to the distance closer to it.

[0007] Preferably, the support plate is provided with a number of through holes.

[0008] Preferably, the diameter of the through hole gradually decreases from top to bottom.

[0009] Preferably, the buoy consists of several floats spaced vertically, all of which are fixed together by several round rods, and gaps are provided between adjacent floats.

[0010] Preferably, the upper side of the float plate is provided with a curved surface, which gradually slopes downward from the middle to the edge.

[0011] Preferably, a number of U-shaped rings are fixed to the upper curved surface, which are evenly distributed in the circumference.

[0012] Preferably, a top frame is fixedly connected to the connecting frame, and a cross frame is fixedly connected inside the top frame. The cross frame is made of elastic material. The warning light is ball-jointed with the light holder, and an elastic element is fixedly connected between the warning light and the light holder. The warning light slides within the cross frame.

[0013] Preferably, a number of elastic blocks are fixed inside the cross frame, and the size of all the elastic blocks increases sequentially from the point closest to the central axis of the lamp holder to the point furthest away.

[0014] Preferably, the lamp holder has a number of rings that are the same as the number of support plates, and a connecting rope is fixed between the support plate and the warning light. The connecting rope passes through the rings on the lamp holder located on the opposite side of the adjacent support plate.

[0015] The beneficial effects of this invention are as follows: This invention buffers the tilting of the support plate by gradually rotating the support plate and storing force through the torsion spring, reducing the tilt angle of the light fixture. Furthermore, when the buoy uses buoyancy to reset the light fixture, the rotation of the torsion spring assists in straightening the light fixture, shortening the tilting time and thus reducing the probability of the warning light being obscured by waves due to tilt. This ensures the warning effect of the device when subjected to external impacts in complex hydrological environments at ports. During the tilting process, the wider part of the support plate automatically rotates to the upper side of the narrower part. The support plate, now wider at the top and narrower at the bottom, pushes the water flow in all directions, using water flow resistance to buffer the movement of the support plate and reduce the tilt angle of the light fixture, thereby ensuring... The stability of the warning light is ensured by the fact that the diameter of the through-hole gradually decreases from top to bottom. Therefore, when water is pushed against the lower side of the support plate, the resistance to the water flowing through the through-hole increases, ensuring that the resistance encountered when the support plate moves with the water flow is reduced, thus buffering the tilt of the light holder. Conversely, when water is pushed against the upper side of the support plate, the resistance to the water flowing through the through-hole decreases, reducing the restoring resistance of the support plate. If the device tilts and causes the support plate to rotate, the support plate pulls the warning light via the corresponding connecting rope. The warning light slides within the cross frame in the opposite direction of the tilt, moving the warning light away from the water surface. This reduces the probability of the warning light being obstructed by water waves, thus improving the stability of the device's warning effect. Attached Figure Description

[0018] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0019] Example 1 A navigation and warning device for basic waterways in port logistics, such as Figures 1-3 As shown, the device includes a buoy 1, a light holder 2 mounted on the buoy 1, a connecting frame 3 mounted on the light holder 2, a warning light 4 mounted on the light holder 2, symmetrically distributed guide rods 301 fixedly connected to the connecting frame 3, symmetrically distributed rotating rods 302 rotatably connected to the connecting frame 3, a sliding frame 303 slidably connected to all guide rods 301, the rotating rods 302 and the sliding frame 303 threadedly connected, several circumferentially evenly distributed support rods 5 rotatably connected to the connecting frame 3, the sliding frame 303 is used to compress all support rods 5, a support plate 6 is rotatably and sealingly connected to the support rods 5, a torsion spring is fixedly connected between the support plate 6 and the adjacent support rod 5, the width of the support plate 6 gradually decreases from the distance away from the central axis of the light holder 2 to the distance closer, and several through holes 7 are provided on the support plate 6, the diameter of the through holes 7 gradually decreases from top to bottom.

[0020] Furthermore, a base is installed at the lower part of buoy 1, and the battery that powers the warning light 4 is located inside the base at the lower part of buoy 1. During the use of this device, the base at the lower part of buoy 1 is immersed in water, and buoy 1 is exposed above the water surface. Buoy 1 is used to provide buoyancy for this device and make this device float stably on the water surface of the channel.

[0021] Furthermore, both the light frame 2 and the connecting frame 3 are welded from metal tubing and profiles. The warning light 4 is used to emit navigation warning light signals in low visibility conditions (such as at night or in heavy fog) to guide ships through the port channel.

[0022] Furthermore, there are two guide rods 301 and two rotating rods 302. When visibility is low, rotating the two rotating rods 302 causes the sliding frame 303 to move upward. The sliding frame 303 compresses all the support rods 5, causing all the support rods 5 to flip outward, thereby causing the support plate 6 to spread outward. Figure 1 The support rod 5 shown is in an outward-opening state, at which time the water surface is below the support plate 6.

[0023] Furthermore, the support rod 5 and the support plate 6 are connected in a sealed rotatable manner to seal the torsion spring.

[0024] Furthermore, when the device shakes (due to ship collision or wave impact), taking the device tilting to the right as an example, the right side of the right support plate 6 first contacts and presses against the water surface. Then, the support plate 6 rotates, and the torsion spring between the support plate 6 and the adjacent support rod 5 stores force. The left side of the support plate 6 gradually comes into contact with the water surface. Through the gradual rotation of the support plate 6 and the torsion storage of the torsion spring, the tilting of the support plate 6 is buffered, reducing the tilt angle of the light frame 2. Moreover, when the buoy 1 drives the light frame 2 to return to its original position through buoyancy, the rotation of the torsion spring assists the light frame 2 in returning to its original position, shortening the tilting time of the light frame 2. This reduces the probability of the warning light 4 being obscured by waves due to tilting, ensuring the warning effect of the device when subjected to external impact in the complex hydrological environment of the port.

[0025] Furthermore, since the width of the support plate 6 gradually decreases from the distance from the central axis of the lamp holder 2 to the distance from the central axis, the portion of the support plate 6 furthest from the central axis of the lamp holder 2 is wider, which enhances the support strength of the support plate 6 when it first touches the water. Then, as the support plate 6 rotates, the portion of the support plate 6 closest to the central axis of the lamp holder 2 gradually contacts the water surface, causing this portion to be gradually pressed into the water. Finally, the wider portion of the support plate 6 is located above the narrower portion. When the lamp holder 2 tilts, the support plate 6, which is wider at the top and narrower at the bottom, pushes the water flow in all directions, using the water flow resistance to buffer the movement of the support plate 6, reducing the tilt angle of the lamp holder 2, thereby ensuring the stability of the warning light 4.

[0026] Furthermore, since the diameter of the through hole 7 gradually decreases from top to bottom, when water is pushed on the lower side of the support plate 6, the resistance of the water flowing through the through hole 7 increases, ensuring the resistance encountered by the support plate 6 when pushing the water to move, thereby ensuring the force to buffer the tilt of the lamp holder 2. When water is pushed on the upper side of the support plate 6, the resistance of the water flowing through the through hole 7 decreases, thereby reducing the reset resistance of the support plate 6.

[0027] Furthermore, in this embodiment, the buoy 1 is connected to a fixed structure on the seabed using existing chains.

[0028] Example 2 Based on Example 1, such as Figure 1 and Figure 2 As shown, the buoy 1 is composed of several floats 101 distributed at intervals. All floats 101 are fixed together by several round rods. There are gaps between adjacent floats 101. The upper side of the float 101 is provided with a curved surface 8. The curved surface 8 gradually slopes downward from the middle to the edge. Several U-shaped rings 9 are fixed on the curved surface 8 located on the upper side.

[0029] Furthermore, water flow is supplied through the gaps between all the floats 101, reducing the impact force on the device when the water flow directly impacts the float 1, thereby reducing the probability that the device will tip over due to the impact of the water flow.

[0030] Furthermore, the curved surface 8 guides the residual water on the float 101 back into the water, reducing the probability of the float 101's buoyancy decreasing due to the crystallization and corrosion caused by residual seawater on the surface of the float 101, thereby ensuring the stability of the float 101.

[0031] Furthermore, in the above embodiments, the buoy 1 is connected to the fixed structure on the seabed by existing chains. In this embodiment, all U-shaped rings 9 are connected by multiple chains, so that multiple chains tighten the four sides of all the floats 101. Multiple chains are connected to the fixed structure on the seabed, reducing the probability of the floats 101 swaying due to the influence of waves, thereby enhancing the stability of the floats 101 and the warning light 4.

[0032] Example 3 Based on Example 2, such as Figure 1 , Figure 2 and Figure 4 As shown, a top frame 10 is fixed to the connecting frame 3, and a cross frame 11 is fixed inside the top frame 10. The cross frame 11 is made of elastic material. The warning light 4 is ball-jointed with the light frame 2. An elastic element is fixed between the warning light 4 and the light frame 2. The warning light 4 slides inside the cross frame 11. Several elastic blocks 12 are fixed inside the cross frame 11. The size of all elastic blocks 12 increases sequentially from the point closest to the central axis of the light frame 2 to the point furthest away. The light frame 2 has the same number of rings 13 as the support plates 6. A connecting rope is fixed between the support plates 6 and the warning light 4. The connecting rope passes through the rings 13 on the light frame 2 located on the opposite side of the adjacent support plates 6.

[0033] Furthermore, the top frame 10 is located above the connecting frame 3. The top frame 10 is used to mount the cross frame 11 and to provide protection for the upper part of the device.

[0034] Furthermore, the cross frame 11 is used to elastically limit and guide the warning light 4, so that the warning light 4 can move within the cross frame 11 when it is impacted by wind and waves. The elastic element between the warning light 4 and the light holder 2 bends and deforms, and the elastic block 12 is used to buffer the displacement of the warning light 4.

[0035] Furthermore, when the device tilts and the support plate 6 rotates, the support plate 6 pulls the warning light 4 through the corresponding connecting rope, causing the warning light 4 to move away from the rotating support plate 6. That is, the warning light 4 slides in the opposite direction of tilting within the cross frame 11. The elastic element between the warning light 4 and the lamp holder 2 bends and deforms, causing the warning light 4 to move away from the water surface, reducing the probability of the warning effect decreasing due to the warning light 4 being blocked by water waves, thereby improving the stability of the warning effect of the device. During the process of the lamp holder 2 resetting, the elastic element between the warning light 4 and the lamp holder 2 resets, and the warning light 4 pulls the connecting rope to reset.

[0036] Furthermore, when the warning light 4 slides in the opposite direction of tilting within the cross frame 11, the gradually increasing elastic block 12 provides step-by-step buffering for the sliding of the warning light 4, reducing the probability of damage to the warning light 4 due to shaking and ensuring the normal use of the warning light 4.

[0037] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
