Technical Field

[0001] The utility model relates to the technical field of power supply for protection lamps of railway track working vehicles, and in particular to a power supply system for double-sided protection lamps of railway track working vehicles. Background Art

[0002] When railway track operation vehicles are parked overnight, double-sided protective lights need to be turned on as a warning.

[0003] The double-sided protective lights installed on the existing railway track working vehicles are set on the top of the track working vehicles and are illuminated by using batteries. For example, the Chinese invention patent application with publication number CN101143586A discloses a wireless early warning device to prevent train rear-end collisions. The scheme records that the strong light protective lights are powered by batteries.

[0004] In order to save energy, railway track working vehicles usually do not generate electricity through the engine after parking. At the same time, the railway track working vehicle needs to be powered by batteries when starting. Therefore, turning on the double-sided protective lights when parking can easily cause the battery to run out of power, which in turn makes the railway track working vehicle unable to start normally; and frequent battery power loss will also reduce the battery life and increase the cost of use. Utility Model Content

[0005] The utility model aims to provide a double-sided protective lamp power supply system for a railway track operation vehicle, so as to solve the problem that the protective lamp of the railway track operation vehicle currently uses the battery of the railway track operation vehicle, which is easy to cause power loss.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A power supply system for a double-sided protection lamp of a railway track working vehicle comprises an external power generation mechanism arranged on the railway track working vehicle and a power storage mechanism electrically connected to the double-sided protection lamp, wherein the external power generation mechanism is electrically connected to the power storage mechanism, and the external power generation mechanism is arranged outside the double-sided protection lamp.

[0008] It is further defined that the external power generation mechanism is a solar photovoltaic panel, the solar photovoltaic panel is arranged on the top of the railway track working vehicle, and the power storage mechanism is arranged inside the railway track working vehicle.

[0009] It is further defined that the double-sided protection light power supply system of the railway track operation vehicle also includes a battery and a switching switch, the battery is arranged inside the railway track operation vehicle, and the battery and the power storage mechanism are electrically connected to the double-sided protection light through the switching switch.

[0010] It is further defined that the railway track operation vehicle double-sided protection lamp power supply system also includes a voltage detection mechanism, and the voltage detection mechanism is electrically connected to the power storage mechanism.

[0011] It is further defined that the power storage mechanism is electrically connected to the switching switch via a voltage detection mechanism.

[0012] It is further defined that the double-sided protection lamp power supply system of the railway track operation vehicle also includes a protection switch, and the switching switch is electrically connected to the double-sided protection lamp through the protection switch.

[0013] It is further defined that the double-sided protection light power supply system of the railway track operation vehicle also includes a photosensitive sensor, the photosensitive sensor is connected in parallel with the protection switch, and the switching switch is also electrically connected to the double-sided protection light through the photosensitive sensor, and the photosensitive sensor is arranged on the top of the railway track operation vehicle.

[0014] It is further defined that the power supply system for the double-sided protective lamp of the railway track operation vehicle also includes a power supply socket, which is electrically connected to the power storage mechanism, and the power supply socket is arranged inside the railway track operation vehicle.

[0015] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0016] 1. The utility model adds an external power generation mechanism outside the railway track working vehicle, which can avoid using the railway track working vehicle's own energy to generate electricity, reduce costs, and be green and environmentally friendly. On the other hand, the electric energy generated by the external power generation mechanism is stored in the power storage mechanism and then powered for the double-sided protective lamp, avoiding the problem of battery power feeding caused by using batteries for power supply, ensuring the service life of the batteries, reducing the cost of maintenance and overhaul, and meeting actual use needs.

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only part of the embodiments of the present utility model, not all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present utility model.

[0023] Example 1

[0024] refer to Figure 1 and Figure 2 The present embodiment provides a double-sided protective lamp power supply system for a railway track operation vehicle, comprising an external power generation mechanism 1 and a power storage mechanism 2, wherein the external power generation mechanism 1 is electrically connected to the power storage mechanism 2, and the power storage mechanism 2 is electrically connected to the double-sided protective lamp 6. The external power generation mechanism 1 can selectively generate electricity through a generator, preferably through renewable energy, such as through the conversion of renewable energy such as wind energy, thermal energy and / or solar energy into electrical energy and storing the electricity through the power storage mechanism 2.

[0025] The external power generation mechanism 1 is preferably a solar photovoltaic panel, which has a more mature market technology and a wider range of applications.

[0026] Solar photovoltaic panels are installed on the top of the railway track operation vehicle by means of screws, magnets or snap-ons, so as to increase the sunlight exposure area and increase the power generation.

[0027] In order to avoid the influence of the external environment and to prevent short circuit caused by rain, the power storage mechanism 2 is arranged in the body of the railway track operation vehicle.

[0028] The power storage mechanism 2 is used to provide lighting voltage for the double-sided protective lamp 6. The voltage of the double-sided protective lamp 6 is usually selected as 24V and the power is selected as 10W, so the power supply voltage of the power storage mechanism 2 can provide 24V voltage. For example, the power storage mechanism 2 can provide three voltage standards: 36V, 24V and 12V.

[0029] In order to meet actual usage requirements, the external power generation mechanism 1 and the power storage mechanism 2 need to be able to work normally in an environment with a temperature of -40℃ to +50℃, and the external power generation mechanism 1 needs to have at least IP67 dust and water resistance level, while the power storage mechanism 2 needs to meet the requirements of the double-sided protective lamp 6 for continuous lighting for 12 hours.

[0030] In order to prevent the power storage mechanism 2 from being unable to continue to supply power to the double-sided protective lamp 6 after the railway track working vehicle has been parked for more than 12 hours due to a decrease in the external ambient temperature or a decrease in the service life of the power storage mechanism 2, it is necessary to ensure that the double-sided protective lamp 6 can continue to maintain lighting as a reminder, so multiple power storage mechanisms 2 can be selected as backup power sources.

[0031] In order to avoid wasting resources and increasing costs, preferably, the railway track operation vehicle double-sided protection lamp power supply system provided in this embodiment also includes a switching switch 4 and a battery 3 on the railway track operation vehicle.

[0032] The power storage mechanism 2 and the battery 3 both switch power supply through the switching switch 4; the switching switch 4 can be selected as a single-pole double-throw switch, and the operator can manually operate the switching switch 4 to switch the power supply to avoid the power storage mechanism 2 being unable to reliably supply power to the double-sided protective lamp 6.

[0033] In order to prevent the staff from failing to promptly discover that the power storage mechanism 2 is low on power or has unstable power supply, the railway track operation vehicle double-sided protective light power supply system provided in this embodiment also includes a voltage detection mechanism 5, which is electrically connected to the power storage mechanism 2 and is used to measure and display the voltage of the power storage mechanism 2. The operator can promptly switch the power supply of the double-sided protective light 6 by switching the switch 4 according to the real-time voltage of the power storage mechanism 2.

[0034] At this time, the voltage detection mechanism 5 is usually set in the cab of the railway track operation vehicle, and can be connected to an audible and visual alarm for reminders. For example, when the voltage value of the power storage mechanism 2 is lower than 22V, a reminder is given to the operator in time.

[0035] To further illustrate, the power storage mechanism 2 can be selected to be electrically connected to the switching switch 4 through the voltage detection mechanism 5, so that the switching switch 4 can automatically switch the power supply according to the voltage detection mechanism 5, thereby reducing the difficulty of manual action, improving the switching efficiency, and ensuring that the double-sided protective light 6 can remain on in a dim environment, meeting the parking reminder requirements of railway track operation vehicles.

[0036] Specifically, the voltage detection mechanism 5 includes a digital voltmeter, an electromagnetic relay and a power-off reset actuator, and the switching switch 4 is selected as a single-pole double-throw switch; the digital voltmeter is electrically connected to the power storage mechanism 2 and is arranged in the cab, the input end of the electromagnetic relay is connected to the output end of the power storage mechanism 2, the output end of the electromagnetic relay is connected to the power supply end of the power-off reset actuator, and the output end of the power-off reset actuator is connected to the rotation position of the single-pole double-throw switch.

[0037] During operation, when the voltage of the power storage mechanism 2 is sufficient, the electromagnetic relay remains energized. At this time, the power storage mechanism 2 supplies power to the power-off reset actuator, driving the single-pole double-throw switch to rotate to the position where the power storage mechanism 2 is connected to the double-sided protective lamp 6. When the voltage of the power storage mechanism 2 drops to the set value, the electromagnetic relay is released, causing the power-off reset actuator to cut off power. At this time, the power-off reset actuator drives the single-pole double-throw switch to rotate to the position where the battery 3 is connected to the double-sided protective lamp 6, thereby realizing automatic power supply switching to meet actual usage needs.

[0038] Further explanation, in order to facilitate the control of the switch of the double-sided protection light 6 and avoid the waste of energy caused by the power consumption of the double-sided protection light 6 when the vehicle is turned on during daytime driving, the double-sided protection light power supply system for the railway track operation vehicle provided in this embodiment also includes a protection switch 7. The protection switch 7 is connected between the double-sided protection light 6 and the switching switch 4. When the protection switch 7 is closed, the power storage mechanism 2 or the battery 3 supplies power to the double-sided protection light 6. When the protection switch 7 is disconnected, it means that the double-sided protection light 6 is not needed for lighting reminder at this time, so there is no need for the power storage mechanism 2 or the battery 3 to supply power to the double-sided protection light 6, thereby saving electricity and reducing costs.

[0039] Further explanation: In order to avoid the situation where the double-sided protective lights 6 fail to turn on in time after the railway track working vehicle is parked due to the operator's error, such as failing to manually close the protective switch 7 in a timely and effective manner, or failing to disconnect the protective switch 7 in a timely and effective manner, such that the double-sided protective lights 6 are always on and cause power waste, the railway track working vehicle double-sided protective light power supply system provided in this embodiment also includes a photosensitive sensor 8.

[0040] The photosensitive sensor 8 is selected to be connected in parallel with the protective switch 7, so that even if the operator forgets to close the protective switch 7 at night, the double-sided protective lamp 6 can be electrically connected to the power storage mechanism 2 or the battery 3 through the switching switch 4 to ensure that the double-sided protective lamp 6 meets the usage requirements.

[0041] To further explain, since the double-sided protective lights 6 do not need to be started during daytime driving, in order to make full use of the electricity generated by the external power generation mechanism 1, a power socket 9 is selected to be set in the railway track operation vehicle. By electrically connecting the power socket 9 to the power storage mechanism 2 through a booster, the personnel on the track operation vehicle can use the power socket 9 to meet charging and other usage needs during daytime driving, thereby maximizing energy utilization.

[0042] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
