Description

Technical Field

[0001] This utility model relates to the field of maintenance railing technology, specifically a multifunctional maintenance railing for water conservancy projects. Background Technology

[0002] Water conservancy projects require protective equipment along their banks to ensure safety and block debris, but existing maintenance barriers are clearly inadequate. They only provide basic isolation and protection, have limited functionality, and lack emergency rescue designs. In the event of an accidental fall into the water, they cannot provide timely and effective rescue assistance, increasing the difficulty and risk of rescue. At night or in dimly lit environments, their warning and lighting capabilities are weak, easily leading people to accidentally enter dangerous areas. Furthermore, rescue tools such as lifebuoys lack suitable storage and quick-access structures; they are prone to shifting and falling off during storage, making them inconvenient to retrieve in emergencies, and failing to meet the actual protection and emergency needs of water conservancy project banks.

[0013] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figure 1-4 The present invention provides a multi-functional maintenance railing for water conservancy projects, comprising: a railing panel 1 and uprights 2 installed at both ends of the railing panel 1, and further comprising: a traction component 3 rotatably installed at the middle position of the railing panel 1, one end of the traction component 3 being attached to a life ring 4, and two sliding grooves 5 being opened on one side of the outer wall of the railing panel 1, with support components 6 installed on the inner walls of the two sliding grooves 5, and a pulling component 7 rotatably connected between the two support components 6, and lighting lamps 8 being installed on the top of the two uprights 2.

[0015] It should be noted here that: Protective function: Multiple guardrails, consisting of "guardrail panels 1 and posts 2" spliced ​​together, are installed on the bank of the water conservancy project to form a continuous protective barrier, preventing people and debris from approaching dangerous water areas and avoiding accidental falls into the water; the fixing holes at the four corners of the bottom of the posts 2 can be connected to the foundation with bolts to ensure that the guardrail is installed firmly and resists the impact of water flow or collisions with people.

[0016] Rescue function; Water rescue initiated: When someone falls into the water, first release the support component 6 from the lifebuoy 4 (this needs to be done in conjunction with pulling component 7), and then throw the lifebuoy 4 into the water; Shore-based traction rescue: The lifebuoy 4 and the traction component 3 are connected by a cable. After the person in the water grabs the lifebuoy 4, the people on the shore rotate the traction component 3 to pull the lifebuoy 4, thereby pulling the person in the water ashore. Water rescue protection: If water rescue is required, rescuers can put the life ring 4 on their body and keep the cable of the pulling component 3 connected. Even if it takes a lot of effort during the rescue, the position can be fixed by the cable to avoid being swept away by the water flow and improve the safety of the rescue.

[0017] Nighttime warning function: At night, the two lights on the top of column 2 will be turned on to warn passersby that "this is a dangerous area of ​​water conservancy project". At the same time, it will provide lighting for nighttime shore patrols and emergency rescues, improving the safety of nighttime use.

[0018] In a preferred embodiment, the pulling assembly 3 includes a winch 301, a cable 303 wound around the winch 301, and a plurality of equidistant handles 302 installed on the outer wall of the winch 301.

[0019] It should be noted here that: Power input: The handles 302 are evenly distributed on the outer wall of the winch 301, providing a point of force for personnel. When personnel on shore hold the handles 302 and rotate the handles, the winch 301 will rotate synchronously. Cable pulling: The cable 303 is wound around the winch 301. When the winch 301 rotates clockwise, the cable 303 is wound and tightened, which can pull the lifebuoy 4 in the water towards the shore.

[0020] In a preferred embodiment, the support assembly 6 includes a sliding rod 601, a spring 602 sleeved on the outside of the sliding rod 601, a slider 603, and an arc-shaped shell 604 mounted on one side of the outer wall of the slider 603.

[0021] It should be noted here that: the two support components 6 are respectively installed in the two sliding grooves 5 of the railing 1. The arc-shaped inner wall of the arc shell 604 is adapted to the outer ring of the life ring 4. Under normal conditions, the two arc shells 604 support the life ring from both sides of the inner ring of the life ring 4 and fix it to one side of the railing 1 to prevent the life ring from shaking or falling off at will, and to make it easy to take it out at any time. Dynamic release of support: When it is necessary to take the lifebuoy 4, the external pulling force is transmitted to the slider 603 through the pulling component 7. The slider 603 slides along the sliding rod 601 to the inside of the sliding groove 5, while compressing the spring 602. The slider 603 drives the arc-shaped shell 604 to move synchronously. The two arc-shaped shells 604 move closer to each other, disengage from the lifebuoy 4, and release the support. At this time, the lifebuoy can be easily removed.

[0022] In a preferred embodiment, the pulling assembly 7 includes a mounting plate 701, a U-shaped piece 702 mounted on one side of the outer wall of the mounting plate 701, and connecting rods 703 rotatably mounted on both ends of one side of the outer wall of the mounting plate 701.

[0023] It should be noted here that the connecting rods 703 on both sides of the mounting plate 701 are rotatably connected to the arc-shaped shells 604 of the two support components. When the U-shaped piece 702 is pulled, the mounting plate 701 drives the two connecting rods 703 to swing synchronously, thereby pushing the two arc-shaped shells 604 and the slider 603 to move closer to each other along the slide groove 5, ensuring that the two support components release the support of the life ring at the same time, and avoiding the life ring from getting stuck due to release on one side. Flexible movement: The rotating connection design between the connecting rod 703 and the arc-shaped shell 604 can adapt to the angle changes of the slider 603 during sliding, ensuring a smooth pulling process without the risk of jamming or getting stuck.

[0024] In a preferred embodiment, the two connecting rods 703 are rotatably connected at opposite ends to the outer walls of the two arc-shaped shells 604.

[0025] It should be noted here that when the mounting plate 701 of the component is moved, the connecting rod 703 will rotate around the connection point with the arc-shaped shell 604, automatically adjusting the tilt angle—avoiding structural jamming caused by the slider 603 of the supporting component sliding in a straight line and the asynchronous movement trajectory of the mounting plate 701 of the component, thus ensuring smooth power transmission.

[0026] In a preferred embodiment, fixing holes are provided at the four corners of the bottom outer wall of both columns 2.

[0027] It should be noted here that the fixing holes provide installation channels for fasteners such as bolts and expansion screws. During installation, the bottom of column 2 should be placed against the foundation or concrete base of the water conservancy project bank, so that the fixing holes are aligned with the pre-set installation holes in the foundation.

[0028] Working principle: This maintenance barrier uses a combination structure of "barrier panel + post + functional components" to achieve three core functions: "protection + emergency rescue + nighttime alert". The collaborative working logic of each component is as follows: Basic protection: Multiple guardrails are spliced ​​and installed on the bank of the water conservancy project by guardrail panels 1 and posts 2 to form a continuous protective barrier to prevent personnel and debris from approaching dangerous water areas; the fixing holes at the four corners of the bottom of the posts 2 are connected to the foundation by bolts to ensure that the guardrails can withstand the impact of water flow or personnel collisions and avoid displacement.

[0029] Emergency rescue triggering and execution: When a person falls into the water, the support component 6 is first released from the support of the lifebuoy 4 by pulling component 7, and the lifebuoy 4 is taken out and thrown into the water; the lifebuoy 4 is connected to the pulling component 3 through the cable 303. After the person in the water grabs the lifebuoy 4, the people on the shore rotate the pulling component 3 and tighten the cable 303 to pull the person ashore; if it is necessary to go into the water for rescue, the rescuers can put the lifebuoy 4 on their bodies and use the cable 303 of the pulling component 3 to maintain the connection with the shore and prevent being swept away by the water flow.

[0030] Nighttime assistance: At night, the lights on the top of column 2 will be turned on, which will warn passersby that "this is a dangerous water area" and provide lighting for nighttime patrols and emergency rescues, thus improving safety.

[0031] II. Working principles of key components; Traction Component 3: Traction Control Core of Lifebuoy 4; Structure: It consists of a winch 301, a handle 302, and a cable 303. One end of the cable is tied to the lifebuoy 4, and the other end is wrapped around the winch 301.

[0032] Work logic: Power input: When the personnel on shore hold the handle 302 on the outer wall of the winch 301, rotating the handle 302 will drive the winch 301 to rotate synchronously. Cable pulling: When the winch 301 rotates forward, the cable 303 is wound and tightened, pulling the lifebuoy 4 in the water toward the shore, helping the person who has fallen into the water to get closer to a safe area.

[0033] Supporting component 6: Storage and release control of lifebuoy 4; Structural composition: includes a sliding rod 601, a spring 602, a slider 603, and an arc-shaped shell 604. Two support components 6 are symmetrically installed in the sliding groove 5 of the railing 1.

[0034] Work logic: Normal support: The arc-shaped inner wall of the arc-shaped shell 604 is adapted to the outer ring of the life ring 4. Under normal conditions, the two arc-shaped shells 604 support the life ring 4 from the inside and fix it to one side of the railing 1 to prevent it from shaking or falling off. Release trigger: When the lifebuoy 4 needs to be retrieved, the external pulling force is transmitted to the slider 603 through the pulling component 7. The slider 603 slides along the sliding rod 601 towards the inside of the slide groove 5, while compressing the spring 602. The slider 603 drives the arc-shaped shell 604 to move synchronously. The two arc-shaped shells 604 move closer to each other, disengage from the lifebuoy 4, and release the support.

[0035] Pulling component 7: Synchronous control of transmission with supporting component 6; Structural composition: It consists of a mounting plate 701, a U-shaped part 702, and a connecting rod 703. The two ends of the connecting rod 703 are rotatably connected to the mounting plate 701 and the arc-shaped shell 604 of the support assembly, respectively.

[0036] Work logic: Concentrated force application: The U-shaped component 702 provides a unified force application point for personnel, eliminating the need to operate the two support components 6 separately. Simply pulling the U-shaped component 702 will transmit the pulling force through the mounting plate 701. Synchronous transmission: The mounting plate 701 drives the connecting rods 703 on both sides to swing synchronously, pushing the two arc-shaped shells 604 and the slider 603 to move closer to each other along the slide groove 5, ensuring that the two support components 6 release the support of the life ring 4 at the same time, and avoiding the life ring 4 from getting stuck due to unilateral movement.

[0037] Lighting 8: Nighttime cues and illumination; Installation location: Fixed to the top of two posts 2, covering the area around the guardrail.

[0038] Working logic: At night or in dim light (such as on cloudy days or at dusk), the lights are turned on to warn passersby that "this is a dangerous area of ​​the water conservancy project" and prevent them from accidentally entering; at the same time, they provide lighting for nighttime shore patrols and emergency water rescues, helping rescuers to quickly locate lifebuoys and operate the pulling components, thus improving rescue efficiency.
