Description

A navigation-aiding light bridge in mountainous areas or near water Technical Field

[0001] The invention relates to the field of navigation-aiding lights, and in particular to a navigation-aiding light bridge in mountainous areas or near water. Background Art

[0002] The approach lighting system (ALS) is a system that provides visual navigation information to approaching aircraft in low visibility conditions during the day and at night, helping pilots to successfully complete the landing of the aircraft.

[0003] To ensure that the optical centers of the approach lighting system's lamps are aligned with those of the runway threshold lights, two design approaches are commonly used for light strips at domestic airports. One approach involves landfill, ensuring the light strip maintains a physical plane consistent with the design elevation. Some airports near lakes or oceans have employed landfill or lake filling for their light strips; some mountainous airports also employ high landfill. This approach facilitates future light strip maintenance, but it also comes at a cost in terms of engineering investment and environmental impact. The other approach involves the use of a tower-like design. In recent years, this approach has been widely adopted for light strips at mountainous airports in my country, offering significant investment and environmental benefits compared to landfill. However, the height of some towers, some exceeding 120 meters, complicates maintenance during airport operations. Some high-rise towers address this issue by adding passenger elevators. However, these elevators require multiple trips for inspecting multiple towers, resulting in low maintenance efficiency and heightened safety concerns, leading to high operating and maintenance costs. In addition, neither of the above two solutions solves the problem that the light strip is affected by road (rail) networks, rivers, lakes, sea areas, and buildings (structures). The coordination and implementation of land acquisition, demolition, and road and line changes are often more difficult than the construction of the light strip itself, resulting in additional waste of investment.

[0004] Patent CN111962955A discloses an airport navigational lighting system comprising a longitudinal beam and multiple steel tower piers. The multiple steel tower piers are spaced vertically along the longitudinal direction of the longitudinal beam and arranged vertically at the bottom of the longitudinal beam. Multiple navigational lighting mounting locations are spaced at intervals along the length of the longitudinal beam. The present invention achieves stable support for the longitudinal beam by arranging the steel tower piers and longitudinal beams perpendicular to each other in the same vertical plane. Multiple navigational lighting mounting locations are spaced apart on the longitudinal beams for installing navigational lighting. This eliminates the need for a dedicated lighthouse for each navigational lighting fixture, reducing construction, operation, and maintenance costs, improving the safety and efficiency of maintenance and overhaul, and shortening the construction period. By flexibly adjusting the longitudinal beam span and the steel tower pier height, the system can adapt to various complex terrains, including mountainous areas and sea crossings.

[0005] This patent discloses a bridge-type navigation light structure, but since it only discloses the bridge model, it does not further limit the actual beam structure of the navigation light bridge. Therefore, conventional beam structures are often based on straight line designs. However, for complex terrain, straight line structures are often difficult to effectively achieve obstacle avoidance, which greatly limits the use scenarios of bridge-type navigation lights.

[0006] Therefore, a kind of mountainous area, waterside navigation aid light bridge is needed to solve the above-mentioned problem.

[0007] Summary of the Invention

[0008] The present invention aims to solve the problem that the single-tower structure in the prior art solves this problem by adding a manned cabin. However, when inspecting multiple lighthouses, workers need to take the cabin up and down many times, which leads to low maintenance efficiency and high-altitude safety hazards, and the operation and maintenance costs of the system remain high. The existing bridge structure has the problem that the conventional beam body used has limited obstacle avoidance ability. The present invention provides a navigation light bridge for mountainous areas and waterside areas, which solves the above problems.

[0009] The present invention provides a navigation-aiding light bridge for mountainous areas or near water, comprising a beam, a plurality of piers and a light group. The beam is a continuous and smooth steel truss structure arranged horizontally. The light group is composed of a plurality of independent light-emitting mechanisms, which are arranged on the upper surface of the beam. The piers are vertical structures, the center lines of the piers coincide with the gravity line, the tops of the piers are connected to the lower surface of the beam, and the beam is connected to the tops of the piers.

[0010] The navigation light bridge for mountainous areas and waterfront areas described in the present invention is preferably configured such that the nodes at the top of each pier are discrete and continuous in a geocentric coordinate system composed of a transverse coordinate plane with the sea level as the transverse coordinate plane, and the axis of the beam is a continuous smooth line segment with linear characteristics passing through the nodes at the top of the pier.

[0011] The navigation light bridge in mountainous areas or near water described in the present invention is preferably configured such that each pier is evenly stressed, and the two end points of the beam are connected to the top of the pier or to the side surface of the mountain.

[0012] The light bridge for aiding navigation in mountainous areas or near water described in the present invention is preferably configured such that the light groups are evenly arranged on the upper surface of the beam.

[0013] The light bridge for navigation aids in mountainous areas or near water described in the present invention is preferably configured such that the bridge piers have a structure in which the smallest diameter increases sequentially from top to bottom.

[0014] The present invention describes a navigation light bridge for mountainous areas or waterfront areas. As a preferred embodiment, the beam body includes an inspection road plate and guardrails arranged on both sides of the inspection road plate. The inspection road plate is arranged horizontally and continuously on the top of the bridge piers and connects the top of each bridge pier in sequence. The highest position height of the guardrail is greater than the highest position height of the inspection road plate.

[0015] The present invention provides a mountainous area or waterside navigation light bridge, as a preferred embodiment, wherein the beam body further comprises a beam body truss unit, which is a truss structure arranged at the top of the inspection road plate and the bridge pier, and the beam body truss unit is arranged in a continuous manner in the transverse direction.

[0016] The present invention provides a navigation light bridge for mountainous areas or waterside areas. As a preferred embodiment, the bridge piers are provided with a transport mechanism that moves vertically along the bridge piers. The top moving end point of the transport mechanism is the contact position between the bridge pier and the beam body, and the bottom moving end point of the transport mechanism is the contact position between the bridge pier and the ground.

[0017] The light bridge for navigation in mountainous areas or near water described in the present invention is preferably configured such that the bridge piers are truss structures.

[0021] (1) This technical solution is based on the sea level arc surface as the basic reference surface. The beam body is based on this plane and presents a linear connection structure with continuous discrete characteristic points. This allows the beam body to undergo reasonable structural transformation according to the terrain characteristics, thus maximizing the obstacle avoidance requirements while ensuring that the stress meets the requirements.

[0022] (2) The lighting groups of this device are connected by a continuous beam body, so that the mobile operation is based on the shortest path between each lighting element, achieving the purpose of reducing construction, operation and maintenance costs;

The beam 1 is a continuous and smooth pedestrian walkway structure arranged horizontally. The light group 3 is composed of several independent light-emitting mechanisms. The light group 3 is arranged on the upper surface of the beam 1. The piers 2 are vertical structures. The center lines of the piers 2 coincide with the gravity line. The tops of the piers 2 are connected to the lower surface of the beam 1, and the beam 1 is connected to the tops of the piers 2.

[0032] The nodes at the top of each pier 2 are discrete with continuous characteristics in the paracentric coordinate system composed of the sea level as the transverse coordinate plane, and the axis of the beam body 1 is a continuous smooth line segment with linear characteristics passing through the nodes at the top of the pier 2.

[0033] In this embodiment, the clear height of the beam 1 is greater than the highest elevation of the terrain, so the beam 1 is linear. The heights of adjacent piers 2 are adjusted according to their locations. The beam 1 is connected to the tops of the piers 2, and the ends of the beam 1 are cantilevered or connected to the side of the mountain through abutments and supports.

[0034] The horizontal spacing between adjacent bridge piers 2 is equal, and the two end points of the beam body 1 are connected to the top of the bridge pier 2 or to the side surface of the mountain.

[0036] The beam body 1 includes an inspection road plate 11, guardrails 12 and beam truss units 13 arranged on both sides of the inspection road plate 11. The inspection road plate 11 is arranged horizontally and continuously at the top of the bridge pier 2, and is connected to the top of each bridge pier 2 in sequence. The highest position height of the guardrail 12 is greater than the highest position height of the inspection road plate 11. The beam truss unit 13 is a truss structure arranged at the top of the inspection road plate 11 and the bridge pier 2. The beam truss unit 13 is arranged horizontally and continuously.

[0037] Pier 2 is equipped with a transport mechanism that moves vertically along the pier. The top end of the transport mechanism is where pier 2 contacts beam 1, and the bottom end is where pier 2 contacts the ground. Pier 2 is a truss structure, shaped like a quadrangular pyramid.

[0038] Optionally, the structure composed of the beam and the piers is a beam bridge, an arch bridge or a low-tower cable-stayed bridge.

[0039] Furthermore, the vertically movable transport mechanism described in this embodiment may adopt a structure such as an elevator or a ladder.
