[0035] In order to make the technical solutions and advantages in the embodiments of the present application clearer, the exemplary embodiments of the present application are further described in detail below with reference to the drawings. Obviously, the described embodiments are only some of the embodiments of the present application, not all the embodiments. It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict.

[0036] In the process of implementing the present application, the inventor found that the existing catenary working vehicle mostly uses an elevator to send the staff to the position close to the catenary, and relies on manual holding of a spray gun to flush the catenary. Relying on manual cleaning, the water pressure and the spray angle are not well controlled, and it is difficult to achieve the cleaning standard in one cleaning operation.

[0037] To solve the above problems, the present application provides a catenary cleaning system. This cleaning system is mainly applied to cleaning the catenary and its components in the track vehicle system, and can be applied to ground track transportation or underground track transportation. The present embodiment takes the application of catenary cleaning in the subway as an example to specifically describe the implementation of the catenary cleaning system.

[0038] Figure 1 The cleaning vehicle structure schematic diagram provided by the present embodiment; Figure 2 The catenary cleaning system structure schematic diagram provided by the present embodiment; Figure 3 The structure schematic diagram of the flow guide pipe provided by the present embodiment; Figure 4 The sewage treatment device structure schematic diagram provided by the present embodiment.

[0039] As shown in Figures 1 to 4 The catenary cleaning system 1 in the present embodiment includes a cleaning device 101 and a sewage collection device 102. The cleaning device 101 is used for directly cleaning the catenary and its components, and includes a flow guide pipe 1012 and a jet nozzle 1011 for spraying water flow. The jet nozzle 1011 is in communication with the water source through the flow guide pipe 1012. The sewage collection device 102 is used for collecting the cleaned sewage together, and is arranged below the water spraying direction of the jet nozzle 1011. The water source or the water supply device provides water with a certain pressure, which flows to the jet nozzle 1011 through the flow guide pipe 1012 and is sprayed out in the direction facing the jet nozzle 1011 through the jet nozzle 1011. The catenary and its components are cleaned by the spraying force and flowability of the water flow. The water flow and the cleaned dirt fall down below the water spraying direction under the action of gravity, and fall into the sewage collection device 102 to avoid scattering to the cleaning vehicle body or the surrounding environment where the catenary cleaning system 1 is installed. The collected sewage waits for the next step of processing.

[0040] The water pressure of the contact network cleaning system provided in the embodiments of the present application can be controlled at the water source, the jet flow direction can be adjusted by adjusting the orientation of the jet nozzle, and a best angle is selected, so that the water pressure and the jet angle do not need to be adjusted manually, and the sewage collecting device can collect the sewage generated in the cleaning operation for subsequent treatment, so as to prevent the sewage from flowing horizontally and polluting the environment. The device effectively enhances the function of the subway cleaning operation vehicle, improves the operation efficiency, saves manpower, reduces the number of operation personnel, reduces the construction cost, and ensures the safe operation of the train.

[0041] Further, the contact network cleaning system 1 can further include a sewage treatment device 104 for purifying the collected sewage, and the sewage treatment device 104 is connected in communication with the sewage collecting device 102 through a sewage guide pipe 1043. The sewage collected in the sewage collecting device 102 flows into the sewage treatment device 104 through the sewage guide pipe 1043, and the sewage is treated and purified.

[0042] On the basis of the above technical solutions, the embodiments provide a specific implementation mode of the sewage treatment device, Figure 4 The structure of the sewage treatment device is shown in Figure 4 as follows:

[0043] The sewage treatment device 104 includes a sewage tank 1041 and a sewage purification device 1042, the sewage tank 1041 is connected in communication with the sewage collecting device 102 through the sewage guide pipe 1043, and the sewage purification device 1042 is connected in communication with the sewage tank 1041 through a pipeline. The sewage flowing into the sewage tank 1041 from the sewage collecting device 102 through the sewage guide pipe 1043 is subjected to sedimentation and solid-liquid separation in the sewage tank 1041, and the dirt flowing with the water flow will be deposited at the bottom of the sewage tank due to its large specific gravity; at the same time, by providing a filtering device at the communication pipeline between the sewage tank and the sewage purification device 1042, further solid-liquid separation can be performed, and the sewage after solid-liquid separation flows into the sewage purification device through the pipeline, and the solid dirt can be treated after the cleaning work is completed. The sewage purification device further purifies the sewage after solid-liquid separation, so that it reaches the standard of recycling.

[0044] Further, the sewage purification device 1042 is further provided with an interface and a pipeline for external discharge, and the purified sewage can be discharged around the cleaning operation vehicle provided with the contact network cleaning system, or can be sent back to the water supply source for recycling to save water resources.

[0045] For the cleaning device 101, the embodiments of the present application provide a specific implementation mode: the flow guide pipe 1012 is a hard pipe, which can be made of hard plastic or metal, etc. Figure 3As shown, the flow guide pipe 1012 is bent into a door-shaped support structure composed of two vertical pipes and a horizontal pipe, the lower ends of the two vertical pipes of the flow guide pipe 1012 are connected to the water source through pipelines, and the jet nozzles 1011 are arranged on the horizontal pipe of the flow guide pipe 1012. The jet nozzles 1011 are multiple and equidistantly arranged on the flow guide pipe and have the same jet direction. When the water jet is sprayed, the water jet sprayed by the multiple jet nozzles 1011 forms a water curtain, and the contact net in the range of the water curtain can be cleaned at one time. When the cleaning vehicle on which the contact net cleaning system is installed travels, the contact net along the way can be cleaned, and the efficiency is high, and the cleaning vehicle does not need to stop and can be cleaned once.

[0046] Further, the jet direction of the jet nozzles 1011 is upward and oblique. Since the contact net 8 is located above the track, i.e., above the train, the obliquely upward arranged jet nozzles are suitable for cleaning the contact net. The included angle between the jet direction and the traveling direction of the vehicle frame during work is an acute angle, and such an angle can make the side of the contact net accessory facing the jet nozzles receive a greater impact force and obtain a better decontamination effect.

[0047] In some embodiments, the cleaning device 101 has two groups, and the two groups of cleaning devices 101 are symmetrically arranged, and the jet directions of the jet nozzles 1011 on the two groups of cleaning devices 101 are oppositely arranged. The contact net cleaning system is installed on the cleaning vehicle, and the two groups of cleaning devices 101 are arranged along the longitudinal direction of the cleaning vehicle. The jet direction of the jet nozzles on one group of cleaning devices is the same as the traveling direction of the cleaning vehicle, and the jet direction of the jet nozzles on the other group is opposite, and the jet water flows are convergent. Generally, when the cleaning vehicle travels, the side of the contact net accessory facing the jet nozzles 1011 having the same jet direction as the traveling direction of the cleaning vehicle receives a greater water impact force and is cleaned more thoroughly, and the other side is opposite. If only one group of cleaning devices is arranged, the two groups of cleaning devices are arranged to follow the cleaning vehicle to advance or retreat, so that each surface of the contact net accessory can be impacted by the water flow, and the cleaning is more thorough.

[0048] Further, the overhead line cleaning system further comprises a roof 105, two ends of the roof 105 are connected with the flow guide pipes 1012 of the two sets of cleaning devices 101 respectively, and the sewage collecting device 102 is arranged on the upper surface of the roof 105 and located below the water spraying direction of the jet nozzle 1011. Since the overhead line 8 is located above, the jet nozzle needs to be arranged on the top of the cleaning vehicle, the two ends of the roof 105 are connected with the transverse pipes of the flow guide pipes 1012 of the two sets of cleaning devices 101 respectively, at this time, the hard flow guide pipe can also support the roof, and the space below the roof can be used to install and arrange other devices or components or assemblies of the cleaning vehicle, for example, the sewage treatment device 104 can be arranged below the roof to improve the space utilization, and the roof can further prevent water from splashing on the devices below the roof in addition to supporting the sewage collecting device.

[0049] Further, the overhead line cleaning system further comprises a support frame 103 arranged between the two sets of cleaning devices 101 for supporting the roof 105 and the sewage collecting device 102 arranged on the upper surface of the roof 105.

[0050] Further, the sewage treatment device 104 is arranged below the roof 105, wherein the sewage tank 1041 is arranged higher than the sewage purifying device 1042.

[0051] As shown in Figure 1 The embodiment also provides a cleaning vehicle, which comprises a vehicle frame 7, a water storage device 3, a water pump unit 4 and the overhead line cleaning system 1 as described above, wherein the water pump unit 4 is connected with the water storage device 3, the water storage device 3 is connected with the flow guide pipe 1012 of the overhead line cleaning system 1, and the water pump unit 4, the water storage device 3 and the overhead line cleaning system 1 are sequentially arranged on the vehicle frame 7. The water storage device 3 can be a water tank or a water tank and the like for storing cleaning water, and the water pump is used to provide water pressure for the water in the water storage device.

[0052] Further, the cleaning vehicle further comprises a generator set 2 arranged on the vehicle frame below the roof 105 of the overhead line cleaning system 1. The generator set 2 is used to provide electric energy for the cleaning vehicle and the devices attached thereto.

[0053] The cleaning vehicle adopting the overhead line cleaning system 1 has the same technical effects as the overhead line cleaning system 1.

[0054] On the basis of the above technical scheme, the embodiment optimizes the cleaning vehicle.

[0056] The cleaning vehicle further comprises a railway tunnel cleaning system 5 arranged at the bottom and / or side of the frame 7, which is used for cleaning the track bed plate, track, induction plate or tunnel wall.

[0057] In addition, the cleaning vehicle further comprises a water supply system including a water storage device, a water power device and a water supply pipeline, which is used for providing cleaning water to each cleaning system.

[0058] The two ends of the frame 7 are provided with the same type of coupler and buffer, which are used for connecting with the power vehicle. In the working state, the frame is driven by the power vehicle to run on the track, and the operator in the operation room starts each cleaning device according to the needs, respectively or simultaneously. The water power device applies different pressures to the water in the water storage device, and supplies the water to each cleaning device through the water supply pipeline to work. According to the actual needs, each cleaning system can be combined or separated for operation under certain specific working conditions. The two ends of the whole vehicle can be connected with the power vehicle, and the vehicle can run in both directions. One round trip can realize twice washing, and realizes the automatic cleaning of the track bed plate, rail fastening, tunnel wall and induction plate of the subway line, which can greatly reduce the number of operating personnel, save labor cost, reduce the labor intensity of operating personnel and reduce the safety risk of vehicle operation.
