Description

Technical Field

[0001] The invention belongs to the field of elevated interval evacuation devices, and in particular relates to an energy device integrating an evacuation platform, solar power generation and lighting. Background Art

[0002] In order to meet the needs of emergency evacuation and daily maintenance of passengers and operators in elevated sections of rail transit projects, elevated sections are generally equipped with evacuation platforms and interval lighting fixtures. Rail transit projects generally have evacuation platforms between two lines to facilitate emergency evacuation of personnel on both sides of the vehicle. Lighting generally adopts the solution of installing lamps on both sides or in the middle of the line.

[0003] like Figure 1 , Figure 2 As shown, when the rail transit traction power supply system adopts the contact rail power supply method, the elevated line has no contact network pillars, and the section lighting generally adopts the high pole lamp solution, that is, lamp pole columns 2 are arranged on both sides of the elevated section rail line, and lighting fixtures 1 are arranged on the top of the lamp pole columns 2. The evacuation platform 4 is arranged between the vehicles 3. The height of the lamp pole columns 2 is about 4.5m and the spacing is about 30m; when the rail transit traction power supply system adopts the overhead contact network power supply method, contact network columns 6 are arranged in the elevated section, and the lighting fixtures 1 for section lighting can be installed on the same pole as the contact network pillars. The contact network columns 6 are installed on the surface of the evacuation platform 4. At present, the section lighting fixtures 1 mostly use high-power LED lamps, and their power supply is drawn from the low-voltage distribution system of the nearest station.

[0004] The above interval lighting scheme has the following disadvantages:

[0005] (1) Traditional elevated section lighting solutions mostly use high-position installation solutions for lamps. Elevated sections are generally long, and when the lamps are installed at a low height, in order to ensure the lighting quality, it is necessary to increase the number of lamps and increase the lamp power, which makes it difficult to supply power over long distances. High-position lighting can provide effective lighting with a reduced number of lamps installed, but at the same time, it causes inconvenience to subsequent operation and maintenance. Due to the high installation height of the lamps, when maintaining and replacing lamps, it is necessary to use ladders to reach the lamps at higher places, which brings inconvenience to maintenance.

[0006] (2) Due to the particularity of rail transit projects, the power supply for lighting fixtures is drawn from the low-voltage power distribution system of the station. The elevated section is generally several kilometers long, and the lighting fixtures in the section are powered by AC 220V. The long-distance transmission of the low-voltage power supply system has problems such as line loss and voltage reduction at the end of the line. Therefore, the cross-section of the power supply cable needs to be increased. In order to ensure the power supply quality, the wire diameter must be increased, resulting in an increase in cable costs.

[0007] (3) The low-voltage power supply cables in the elevated section are generally laid on the cable bracket under the middle evacuation platform. When the lamps are installed on both sides of the track line, the line must cross the track to be laid to the lamps, and the crossing conditions must be reserved in advance; if the lamps are installed on the middle column of the line, they must pass through the evacuation platform board to be led up to the lamps, and holes must be reserved in the evacuation platform board in advance, which increases the difficulty of coordination and construction. The distribution pipelines of lighting fixtures need to pass through the evacuation platform or the track area, which causes certain inconveniences to the construction. Summary of the invention

[0008] In view of the technical problems existing in the prior art, the present invention provides an energy device integrating evacuation platform, solar power generation and lighting, which solves the installation problem of lighting fixtures in elevated sections, facilitates maintenance and reduces pipeline laying costs.

[0009] The present invention adopts the following technical solutions to solve the above problems:

[0010] An energy device integrating evacuation platform, solar power generation and lighting, comprises an evacuation platform arranged in the middle of an elevated section track, the evacuation platform is embedded with a composite high-strength solar panel, the solar panel is integrally formed with the upper surface of the evacuation platform, a dedicated controller is connected to the bottom of the solar panel, the dedicated controller is connected to and controls energy management components and functional components, the functional components include lighting accessories, communication accessories, indication accessories and other supporting components, the lighting accessories are arranged on both side edges of the evacuation platform close to the elevated section track, and the indication accessories are arranged on both sides of the upper surface of the solar panel.

[0011] Furthermore, the solar panels can be installed at intervals on the surface of the evacuation platform according to actual usage conditions. The solar panels have a certain carrying capacity to meet the needs of personnel passage and have solar power generation capabilities. The solar cells use single-crystal silicon cells with high power generation efficiency.

[0012] Furthermore, the lighting accessory adopts a DC LED lighting accessory, which is powered by an energy management component and is used to provide sufficient illumination for operation and maintenance personnel and passenger evacuation.

[0013] Furthermore, the indication accessory adopts a luminous evacuation indication sign, and the evacuation indication sign adopts direct current power supply, which can be powered by an energy management component in an emergency to provide evacuation path orientation.

[0014] Furthermore, the energy management component includes a battery for storing solar energy and a DC drive power module for powering the lighting accessory, and the DC drive power module is fixedly installed on the back of the DC LED lighting accessory.

[0015] Furthermore, the battery is a fully sealed maintenance-free deep cycle lead-acid battery for storing the electrical energy generated by the solar panels during the day.

[0016] Furthermore, the communication accessory includes a wireless communication module, which is installed on the side wall of the dedicated controller. The wireless communication module uses a 4G communication module to achieve real-time uploading of the device's operating status, fault information, and power generation data.

[0017] Furthermore, the supporting components include a metal shell and a heat-insulating material, the dedicated controller, the energy management component and the communication accessories are arranged inside the metal shell, and the heat-insulating material is arranged between the dedicated controller, the energy management component, the communication accessories and the metal shell.

[0018] Furthermore, the components of the energy management component and the functional component are interconnected through copper wires and shielded communication lines.

[0019] Furthermore, it also includes a light sensor, which is connected to a dedicated controller and is arranged on both side edges of the evacuation platform close to the elevated section track.

[0020] The beneficial effects of the present invention are:

[0021] 1. The present invention proposes a multifunctional energy device integrating an evacuation platform, solar power generation and lighting, and an optimized interval lighting distribution system solution, which combines lighting fixtures with the evacuation platform, saves the structural plates of the evacuation platform, solves the problem of installing lighting fixtures in elevated intervals, and avoids the problem of installing lamps too high and being inconvenient for maintenance.

[0022] 2. The present invention adopts on-site power generation and on-site consumption, with only internal wiring and no external power supply lines, saving a large number of lighting cables. Taking a 1000m section as an example, it can save about 2000m of trunk cables and about 1000m of branch wires (the installation height is calculated as 4.5m and the spacing is 30m); it saves the construction cost of laying pipelines.

[0023] 3. Traditional lighting methods require power supply lines. A failure in a lamp or line in the same power supply circuit will affect the normal operation of other lighting lamps in the entire power supply circuit. The device of the present invention is relatively independent, and there is no hard wire connection between devices. The failure of a device does not affect the normal operation of other devices, thereby improving the reliability of the entire elevated section lighting system.

[0024] 4. The LED lamp itself is DC driven. The traditional AC power supply method requires an AC / DC rectifier module to be installed in the lamp. This device directly uses a DC power supply method to solve the problems of poor reliability and life bottleneck of the LED AC drive power supply, give full play to the advantages of the long life of the LED chip itself, and at the same time improve the energy utilization rate of the lamp.

[0025] 5. The operating data of this device is transmitted wirelessly to the centralized management and monitoring host, which can monitor the operating status of the equipment in real time. Once a fault occurs, an alarm signal is issued, and the operation and maintenance personnel complete the maintenance in time, ensuring the safe operation of the rail transit line.

The lighting accessories are arranged on the two side edges of the evacuation platform 4 close to the elevated section track, and the indication accessories are arranged on both sides of the upper surface of the solar panel 701.

[0043] The lighting accessories use a DC LED lighting accessory 703, which is powered by an energy management component. The DC LED lighting accessory 703 is used to provide sufficient illumination for operation and maintenance personnel and passenger evacuation.

[0044] The indication accessory adopts a luminous evacuation indication mark 702, and the evacuation indication mark 702 adopts direct current power supply, and can be powered by a battery 704 in an emergency to provide evacuation path indication.

[0045] The DC LED lighting accessory 703 and the evacuation indication sign 702 are both powered by DC with a voltage of 36V.
