A type of traffic signal beacon used to ensure safe passage in controlled river sections

Abstract

This utility model relates to the field of waterway equipment technology and discloses a navigation signal beacon for ensuring safe passage in controlled river sections. It includes a buoy body, with connecting arms rotatably connected to the upper left and right sides of the buoy body via bearing seats. A signal light is fixedly connected to the upper end of the connecting arms, and an anchoring chain is fixedly connected to the lower end of the buoy body. Mounting holes are provided on the lower side wall of the buoy body. It also includes a swing drive mechanism installed on the upper end of the buoy body. This utility model utilizes the natural water flow of the river as the sole power source. After turbine blade intake, reversal of the first and second bevel gears, and reduction and torque amplification by a reduction gearbox, the continuous rotation is converted into rhythmic swinging of the signal light by an eccentric turntable in conjunction with a first ball seat, a first ball head, a connecting rod, a second ball head, and a second ball seat. This fundamentally overcomes the visual adaptation and alertness fatigue of the crew, allowing for clear long-distance identification even at night, in rain, snow, and under conditions of stray light interference, significantly improving the safety of passage in controlled river sections.

Description

Technical Field

[0001] This utility model relates to the field of waterway tool technology, and in particular to a passage signal beacon used to ensure the safety of passage in controlled river sections. Background Technology

[0002] The upper reaches of the Yangtze River are a vital waterway for navigation, characterized by high vessel density and complex navigation conditions. Navigation safety directly impacts the overall efficiency of this vital waterway. To improve navigation efficiency and safety, intelligent traffic signal control systems have been gradually implemented in recent years. These systems use LED photoelectric traffic signal markers to replace traditional flag and light signals, enabling remote, unattended signal display and command.

[0003] Existing LED traffic signal markers are generally fixedly installed on poles or towers. They send instructions such as "go up", "go down", and "wait" to ships using red / green / yellow single colors. They have advantages such as high brightness, long visibility distance, and remote dimming, which can improve visibility conditions at night and in foggy weather to a certain extent.

[0004] However, in actual operation, the aforementioned signal signs are all continuously statically displayed without any dynamic changes. According to visual physiology research, the human eye's sensitivity to static light sources decreases exponentially with prolonged fixation time, easily leading to "visual adaptation" and "vigilance fatigue." Especially at night, in rain, snow, or complex weather conditions with background clutter, static light signals are more likely to be ignored or misjudged by drivers, posing significant safety hazards. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, this utility model provides a navigation signal beacon for ensuring the safety of navigation in the controlled river section, so as to solve the problem that the visual adaptation and alertness of the crew are reduced due to the static light signal not changing for a long time, which makes it easy to ignore or misread at night or under complex weather conditions, thus causing ships to mis navigate or block the way, threatening the safety of navigation in the controlled river section.

[0006] This utility model provides a traffic signal beacon for ensuring safe passage in a controlled river section, comprising a buoy body, connecting arms rotatably connected to the upper left and right sides of the buoy body via bearing seats, a signal light fixedly connected to the upper end of the connecting arms, an anchor chain fixedly connected to the lower end of the buoy body, and mounting holes provided on the lower side wall of the buoy body; further comprising:

[0007] A swaying drive mechanism is installed on the upper end of the buoy body and is used to drive the connecting arm to oscillate back and forth.

[0008] Preferably, a connecting rod is rotatably connected between the pair of connecting arms via a bearing housing.

[0009] Preferably, the oscillation drive mechanism includes a turntable, a reduction gearbox is fixedly connected to the upper end of the buoy body, the turntable is fixedly connected to the output shaft end of the reduction gearbox, a connecting shaft is rotatably connected to the inside of the turntable at an offset position, the upper end of the connecting shaft extends through to the upper end of the turntable and is fixedly connected to a first ball seat, a first ball head is movably connected inside the first ball seat, a connecting rod is fixedly connected to the side wall of the first ball head, a second ball head is fixedly connected to the end of the connecting rod away from the first ball head, a second ball seat is movably sleeved on the outer wall of the second ball head, and the left end of the second ball seat is fixedly connected to the right end of the connecting arm on the left side of the buoy body. The oscillation drive mechanism also includes a drive assembly.

[0010] Preferably, the drive assembly includes a rotating shaft, a mounting bracket is fixedly connected inside the mounting hole, the rotating shaft is rotatably connected inside the mounting bracket, a turbine blade is fixedly connected to the left end of the rotating shaft, a first bevel gear is fixedly connected to the right end of the rotating shaft, a second bevel gear meshes with the side wall of the first bevel gear, a transmission rod is fixedly connected to the upper end of the second bevel gear, the upper end of the transmission rod passes through the buoy body and is rotatably connected thereto, and the upper end of the transmission rod is fixedly connected to the input end of the reduction gearbox.

[0011] Preferably, a sealing box is fixedly connected to the right end of the mounting bracket, the first bevel gear and the second bevel gear are both located inside the sealing box, and the rotating shaft and the transmission rod both pass through the sealing box and are rotatably connected to it.

[0012] Preferably, a protective cover is fixedly connected to the upper end of the buoy body. The protective cover covers the entire connection part of the swing drive mechanism, the connecting arm and the signal light. The protective cover is made of transparent and weather-resistant material.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model utilizes the natural water flow of the river as the sole power source. After being absorbed by turbine blades, reversing through the first and second bevel gears, and reducing speed and increasing torque through a reduction gearbox, the continuous rotation is converted into the rhythmic oscillation of the signal light by an eccentric turntable in conjunction with the first ball seat, the first ball head, the connecting rod, the second ball head, and the second ball seat. This fundamentally overcomes the visual adaptation and alertness fatigue of the crew, and can still be clearly identified at a long distance in night, rain, snow, and stray light interference environments, significantly improving the safety of passage in the controlled river section.

[0015] 2. This utility model places the swing drive mechanism, connecting arm and signal light as a whole inside a transparent weather-resistant protective cover, while the drive components are sealed in an underwater sealed box, forming a double isolation requirement of "anti-collision above water and anti-corrosion underwater", which greatly reduces maintenance costs.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1-5 As shown, this utility model has the following two specific embodiments.

[0025] Example 1

[0026] A traffic signal beacon for ensuring safe passage in a controlled river section includes a buoy body 1, with connecting arms 3 rotatably connected to the left and right sides of the upper end of the buoy body 1 via bearing seats. A signal light 31 is fixedly connected to the upper end of the connecting arms 3, and an anchor chain 2 is fixedly connected to the lower end of the buoy body 1. Mounting holes 11 are provided on the lower side wall of the buoy body 1. It also includes:

[0027] The swing drive mechanism 4 is installed on the upper end of the buoy body 1 and is used to drive the connecting arm 3 to swing back and forth.

[0028] A connecting rod 5 is rotatably connected between a pair of connecting arms 3 via a bearing seat;

[0029] A protective cover 6 is fixedly connected to the upper end of the buoy body 1. The protective cover 6 covers all the connection parts of the swing drive mechanism 4, the connecting arm 3 and the signal light 31. The protective cover 6 is made of transparent and weather-resistant material.

[0030] In this embodiment, as Figures 1-2 As shown, the mounting hole 11 is located below the waterline and near the bottom. It uses the natural water flow of the river as the only power source. In conjunction with the swing drive mechanism 4, it drives the connecting arm 3 to swing back and forth. The swing of the connecting arm 3 drives the signal light 31 to move back and forth, thereby fundamentally overcoming the visual adaptation and alertness fatigue of the crew. It can still be clearly identified at a distance in the night, rain, snow and stray light interference environment, which significantly improves the safety of passage in the controlled section of the river. By covering the connection parts of the swing drive mechanism 4, the connecting arm 3 and the signal light 31 inside the protective cover 6, the intrusion of rainwater, waves and floating objects can be avoided.

[0031] Example 2

[0032] The difference from Embodiment 1 is that this embodiment discloses a swing drive mechanism 4;

[0033] The oscillating drive mechanism 4 includes a turntable 42, a reduction gearbox 41 fixedly connected to the upper end of the buoy body 1, the turntable 42 fixedly connected to the output shaft end of the reduction gearbox 41, a connecting shaft 43 rotatably connected to the inside of the turntable 42 at an offset position, the upper end of the connecting shaft 43 extending through to the upper end of the turntable 42 and fixedly connected to a first ball seat 44, a first ball head 45 movably connected inside the first ball seat 44, a connecting rod 46 fixedly connected to the side wall of the first ball head 45, a second ball head 47 fixedly connected to the end of the connecting rod 46 away from the first ball head 45, a second ball seat 48 movably sleeved on the outer wall of the second ball head 47, and the left end of the second ball seat 48 fixedly connected to the right end of the connecting arm 3 on the left side of the buoy body 1. The oscillating drive mechanism 4 also includes a drive assembly 49.

[0034] The drive assembly 49 includes a rotating shaft 492, a mounting bracket 491 fixedly connected inside the mounting hole 11, the rotating shaft 492 being rotatably connected inside the mounting bracket 491, a turbine blade 493 fixedly connected to the left end of the rotating shaft 492, a first bevel gear 494 fixedly connected to the right end of the rotating shaft 492, a second bevel gear 495 meshing with the side wall of the first bevel gear 494, a transmission rod 496 fixedly connected to the upper end of the second bevel gear 495, the upper end of the transmission rod 496 passing through the buoy body 1 and rotatably connected thereto, and the upper end of the transmission rod 496 being fixedly connected to the input end of the reduction gearbox 41.

[0035] A sealing box 497 is fixedly connected to the right end of the mounting bracket 491. The first bevel gear 494 and the second bevel gear 495 are both located inside the sealing box 497. The rotating shaft 492 and the transmission rod 496 both pass through the sealing box 497 and are rotatably connected to it.

[0036] In this embodiment, as Figures 2-5 As shown, the reduction gearbox 41 is a purchased planetary gearbox, centrally fixed to the upper surface of the buoy body 1, with its output shaft extending upwards and locked to the center of the turntable 42; a connecting shaft 43 is rotatably connected to the turntable 42 near its edge, with its upper end protruding from the top of the turntable and fixedly connected to a first ball seat 44; the first ball head 45 can swing in any direction after being embedded in the ball seat, and the outer end of the ball head is fixedly connected to one end of the connecting rod 46, while the other end of the connecting rod 46 is also fixedly connected to a second ball head 47, the outer spherical surface of the second ball head 47 mates with the ball socket of the second ball seat 48, and the back side of the second ball seat 48 is welded to the inner stiffening plate of the left connecting arm 3. When the turntable 42 rotates, the eccentrically arranged first ball head 44... A ball seat 44, a first ball head 45, a connecting rod 46, a second ball head 47, and a second ball seat 48 convert the circular motion into the reciprocating swing of the connecting arm 3 around the bearing seat, thereby driving the signal lights 31 on both sides to swing synchronously left and right; a mounting bracket 491 is horizontally welded inside the mounting hole 11, and a rotating shaft 492 rotates inside the mounting bracket 491. The left end of the rotating shaft 492 is fixedly connected to the turbine blade 493. Since the turbine blade 493 is exposed in the flow channel, the water flow drives the turbine to drive the first bevel gear 494 and the second bevel gear 495, the transmission rod 496, the reduction gearbox, and the turntable 42 to rotate in sequence, so as to realize the signal light 31 swinging without electricity.

[0037] The working principle of this utility model is as follows:

[0038] After the buoy 1 is moored by the anchor chain 2, the turbine blades 493 rotate against the current. The torque is increased through the rotating shaft 492, the first bevel gear 494 and the second bevel gear 495, and then sent to the reduction gearbox 41 through the transmission rod 496. The output end of the reduction gearbox drives the turntable 42 to rotate at a low and uniform speed. The eccentric connecting shaft 43 on the turntable 42 drives the first ball seat 44 to make a circular motion. Through the connecting rod 46, the first ball head 45, the second ball head 47 and the second ball seat 48, it is converted into a periodic push and pull on the connecting arm 3, so that the connecting arm 3 swings back and forth around the bearing seat. The signal lights 31 on both sides swing left and right in sync, forming a continuous dynamic light signal. The protective cover 6 and the sealing box 497 jointly isolate water vapor and floating debris. The crew can obtain passage instructions in any weather by the obvious swinging lights.

[0039] Although the disclosure is as stated above, the scope of protection of this disclosure is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this disclosure, and all such changes and modifications will fall within the protection scope of this utility model.
