Description

Technical Field

[0001] The present invention relates to the technical field of electrical control of railway engineering vehicles, and in particular to a multi-power supply integrated system and a sewage suction vehicle group suitable for railway track sewage suction vehicle groups. Background Art

[0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] High-speed railways and intercity railways have a high proportion of long and large tunnels, and long-term operation will generate some dirt, mainly in the form of dust deposited in the fasteners of the ballast bed, solid fragments dropped from the concrete structure, dirt deposited in the grooves of the track plate, and tiny stones dropped on the ballast bed, especially iron filings and other dirt generated during the operation of the rail grinding vehicle, which are difficult to clean after being hardened. The treatment of these ballastless track dirt has not attracted much attention. Only after the rail grinding vehicle has finished grinding, the engineering protection personnel will carry blowers, diesel or gasoline, fire extinguishers and other related equipment to pick up and blow clean the ballastless track along the grinding line. Picking up and blowing can only temporarily solve the surface problem of iron filings and larger iron blocks from the grinding of the rails on the ballast bed, and cannot effectively clean the dust deposited in the fasteners of the ballast bed; solid fragments dropped from the concrete structure; and dirt deposited in the grooves of the track plate. Therefore, the railway track sewage suction vehicle group is of great significance to keeping the track line clean, ensuring driving safety, and reducing operating costs.

[0004] The inventor found that the original railway track sewage suction vehicle group had no walking power and needed to be towed by a locomotive or operated in a group with a rail grinding vehicle. According to the new line operation safety requirements, the rail grinding vehicle is a maintenance vehicle, not a traction locomotive, and cannot be towed and coupled with other trains. At the same time, the railway track sewage suction vehicle group has no backup AC power supply. When the operating generator set fails, the sewage suction device cannot be restored to the initial position and can only wait for rescue, affecting the line safety. Summary of the invention

[0005] In order to solve the above problems, the present invention provides a multi-power integrated system and a sewage suction vehicle group suitable for railway track sewage suction vehicle groups. Multiple power sources are designed for the railway track sewage suction vehicle groups. In addition to meeting normal operation, the generator sets can cooperate with each other for mutual rescue as an emergency plan to ensure the safe operation of the line. It can solve the problem in the prior art that the railway track sewage suction vehicle groups have no running power and no backup AC power supply for emergency rescue.

[0006] In order to achieve the above object, the present invention adopts the following technical solution:

[0007] A multi-power integrated system suitable for railway track sewage suction vehicles, comprising:

[0008] A main controller configured to control the start and stop of the working generator set, the traction generator set, the auxiliary generator set and the battery set, and display the status parameters;

[0009] The operating generator set is configured to provide power for the sewage suction operation of the sewage suction vehicle set, and to provide power for the vehicle brake unit when the traction generator set fails;

[0010] The traction generator set is configured to provide traction power for the vehicle and provide power for the sewage suction operation when the operating generator set is not working;

[0011] The auxiliary generator set is configured to provide power to the preheating device and / or the air conditioning and ventilation unit when the working generator set and / or the traction generator set fails.

[0012] In the scheme of the present invention, the traction generator set and the working generator set complement each other. When the working generator set fails, the traction generator set can provide power for the sewage suction operation of the whole vehicle; when the traction generator set fails, the working generator set can provide power for the vehicle braking unit.

[0013] In some other embodiments, the following technical solutions are adopted:

[0014] A railway track sewage suction vehicle group adopts the above-mentioned multi-power supply integrated system.

[0015] As a further solution, the railway track sewage suction vehicle group includes a first car body and a second car body; the main controller and the traction generator set are arranged on the first car body, and the operating generator set and the auxiliary generator set are arranged on the second car body.

[0016] Beneficial effects of the present invention:

[0017] (1) The working generator set and the traction generator set of the present invention cooperate with each other and complement each other. When the working generator set fails, the traction generator set can provide power for the whole vehicle sewage suction operation; when the traction generator set fails, the working generator set can provide power for the vehicle braking unit. The two power sources complement each other, so there is no need for a high-power standby generator set, which saves costs and can prevent the vehicle from being overweight.

[0018] (2) The present invention is designed with an auxiliary generator set to provide power to the preheating device when the temperature is too low and the traction generator set cannot be started; it also provides power to the air conditioning and ventilation unit when both the operating generator set and the traction generator set fail. In extreme cases, when both generator sets fail, the auxiliary generator set can still provide AC power to create a comfortable environment for the operators.

[0019] (3) The present invention designs a battery pack as a backup power source to provide a DC power source when the operating generator set fails or is not running. All lighting is powered by a DC generator set, so when not in operation, the operating generator set does not need to be turned on, saving energy. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Embodiment 1

[0027] In one or more embodiments, a multi-power integrated system suitable for a railway track sewage suction vehicle group is disclosed, referring to Figure 1 ,include:

[0028] A main controller configured to control the start and stop of the working generator set, the traction generator set, the auxiliary generator set and the battery set, and display the status parameters;

[0029] The main controller is installed on the main driver's console and is the power operation center of the vehicle. It is used to control the start and stop of the operating generator set, traction generator set, auxiliary generator set and battery pack. At the same time, the operating status and parameters of each generator set are displayed on the console. The AC power required by the main driver's console is supplied by the operating generator set, and the required DC power is provided by the battery pack.

[0030] The operating generator set is configured to provide power for the sewage suction operation of the entire vehicle, and to provide power for the vehicle braking unit when the traction generator set fails.

[0031] The traction generator set is configured to provide traction power for the entire vehicle. At the same time, when the operating power supply is not working, it can provide a certain power supply to the operating system to save energy.

[0032] The auxiliary generator set is configured to provide power to the preheating device and / or the air conditioning and ventilation unit when the working generator set and / or the traction generator set fails.

[0033] Specifically, when the temperature is too low and the traction generator set cannot be started, power is provided to the preheating device of the traction generator set; when both the operating generator set and the traction generator set fail, power is provided to the air conditioning and ventilation unit.

[0034] The battery pack, as a backup power source, outputs DC power. When the operating generator set fails or is not running, it provides DC power to the vehicle lighting unit and control unit.

[0035] It should be noted that, in this embodiment, the air conditioning and ventilation unit, the vehicle lighting unit and the control unit are all the original structures of the sewage suction vehicle group;

[0036] Among them, the air conditioning and ventilation unit creates a comfortable working environment for the operator and is powered by an AC power supply. During normal operation, the operating generator set provides power, but when the operating generator set is not running or fails, the auxiliary generator set provides power to ensure the working environment.

[0037] Vehicle lighting units, including headlights, sign lights, auxiliary lights, studio lights, passage lights, and underbody lights, are all powered by DC power. During normal operation, the power of the operating generator set is converted to DC power through the AC-DC power module. When the operating generator set fails or is not running, it automatically switches to DC power provided by the battery pack.

[0038] The control unit, including the control of the operation process such as sewage suction, the display of driving parameters during traction operation, etc., are all powered by a DC power supply. During normal operation, the power supply of the operating generator set is converted to a DC power supply through the AC-DC power module. When the operating generator set fails or is not running, it automatically switches to a DC power supply provided by the battery pack.

[0039] As a specific implementation scheme, refer to Figure 1The operating generator set is connected to the first electric control cabinet, which serves as a power distribution cabinet. The first electric control cabinet distributes power to the second electric control cabinet, the third electric control cabinet and the fourth electric control cabinet. The second electric control cabinet is configured to supply power to the control unit, the vehicle lighting unit and the main controller of the whole vehicle sewage suction operation; the third control cabinet is configured to provide power to the whole vehicle braking unit when the traction generator set fails; the fourth electric control cabinet is the power electric control cabinet of the high-pressure water pump used in the tunnel sewage suction vehicle group, and the power electric control cabinet distributes power to the high-pressure spraying system and the flushing auxiliary system in the sewage suction vehicle group.

[0040] The second and third electric control cabinets are responsible for the power supply and control of the vehicle operation system. The second electric control cabinet is also the control electric control cabinet of the vehicle operation system. The third electric control cabinet is the power electric control cabinet, and high-power components are installed in the third electric control cabinet.

[0041] The second electric control cabinet provides AC power to the main driver's console and provides power to the air conditioning and ventilation unit.

[0042] Furthermore, the second electric control cabinet has an AC-DC power module, which converts AC power into DC power for the vehicle lighting unit, control unit and main driver console.

[0043] The third electric control cabinet contains a DC-DC power supply module, which provides DC110V power to the main driver's console.

[0044] Furthermore, when the traction generator set fails and locomotive traction rescue is required, the third electric control cabinet provides DC110V power to the braking system.

[0045] In addition, the first electric control cabinet receives the power output by the traction generator set. The traction generator set cannot provide additional high-power power to the sewage suction operation system. Due to the limitation of the vehicle axle weight, a certain power is output to the first electric control cabinet to meet the needs of the auxiliary system. It is also an emergency measure. When the operating generator set fails, the power of the traction generator set is used. There is a dual power switch in the first electric control cabinet, which can automatically switch between two power supplies.

[0046] The traction generator set outputs power to the fifth electric control cabinet, which supplies power to the rectifier cabinet and the brake unit. The fifth electric control cabinet is the power distribution cabinet of the traction generator set, which outputs power to the rectifier cabinet, which converts the power into AC-DC-AC and provides power to the traction motor to drive the entire vehicle.

[0047] When the traction generator set fails, the third electric control cabinet under the operating generator set provides power to the braking system.

[0048] When the operating generator set fails, the traction generator set provides power to the first electric control cabinet to meet the needs of auxiliary equipment.

[0049] The auxiliary generator set is a small-power standby auxiliary generator set. When the temperature is too low and the traction generator set cannot start, it provides power for the preheating device;

[0050] The auxiliary generator set outputs power to the sixth electric control cabinet, which has a dual power automatic switch. When the operating generator set fails, it provides power to the air conditioning and ventilation system.

[0051] The layout principle of the above-mentioned electric control cabinet is to be as close to the electrical equipment as possible, shorten the power supply distance and reduce line loss.

[0052] The vehicle lighting unit and control unit are DC power supplies. When the operating generator set fails or is not running, the power detection module in the battery pack system will be activated and automatically switch to the battery pack to provide DC power to the vehicle lighting unit and control unit.

[0053] Embodiment 2

[0054] In one or more embodiments, a railway track sewage suction vehicle group is disclosed, which adopts the multi-power integrated system described in Example 1, referring to Figure 2 The railway track sewage suction vehicle group specifically includes car No. 1 and car No. 2; the main driver's console in Example 1 is on car No. 1, which serves as the power operation center of the entire vehicle; the operating generator set is arranged on car No. 2 to provide power for the sewage suction operation of the entire vehicle.

[0055] Specifically, car No. 1 includes a driver's cab, a brush roller device, a sewage suction device and a traction system. Car No. 2 includes an operating generator set, a water tank and a high-pressure flushing system. The connection between the two cars includes a coupler, a main air duct, a brake pipe, a power supply line, a control cable and a signal cable. This layout takes into account the load and power distribution. Because the traction motor is in car No. 1, the traction generator set is in car No. 1.

[0056] Since the sewage suction operation device is installed in both car No. 1 and car No. 2, the first electric control cabinet serves as a power distribution cabinet, outputting two power supplies to the second electric control cabinet, the third electric control cabinet and the fourth electric control cabinet respectively.

[0057] The second and third electric control cabinets are located on car No. 1, responsible for the power supply and control of the vehicle operation system. The second electric control cabinet is also the control electric control cabinet for the vehicle operation system. The third electric control cabinet is the power electric control cabinet, and high-power components are installed in the third electric control cabinet. The fourth electric control cabinet is arranged in car No. 2, providing power to the electrical equipment of car No. 2.

[0058] The traction generator set is arranged on car No. 1 to provide traction power for the whole vehicle. The fifth electric control cabinet, rectifier cabinet and brake unit connected to the traction generator set are all arranged on car No. 1.

[0059] The auxiliary generator set is arranged on car No. 2 and is a small-power standby auxiliary generator set. When the temperature is too low and the traction generator set cannot start, it provides power for the preheating device.

[0060] The battery pack is installed on car No. 1 as a backup power source and outputs DC power.

[0061] In this embodiment, the power supply is arranged close to the driving device, which can shorten the power supply cable and reduce the voltage drop.

[0062] Although the above describes the specific implementation mode of the present invention in conjunction with the accompanying drawings, it is not intended to limit the scope of protection of the present invention. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art on the basis of the technical solution of the present invention without creative work are still within the scope of protection of the present invention.
