[0018] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0019] In order to solve the technical problem of how to remove snow and ice from tracks and contact lines in full coverage of railways in the event of cold and snow disasters, the present invention provides an intelligent multifunctional railway disaster prevention rail vehicle that can remove snow and ice from tracks and contact lines in full coverage of railways in the event of cold and snow disasters.

[0020] It should be noted that the intelligent multifunctional railway disaster prevention railcar described in the present invention is used for but not limited to railway snow removal, ice removal and debris removal. For the convenience of explanation, in the present invention, only the application of the intelligent multifunctional railway disaster prevention railcar to comprehensive railway snow removal, ice removal and debris removal is taken as an example for explanation. The principle of applying the intelligent multifunctional railway disaster prevention railcar to only snow removal, only ice removal or only debris removal is essentially the same as the principle applied to comprehensive railway snow removal, ice removal and debris removal, and will not be elaborated here.

[0021] See also Figure 1-2 , Figure 1 This is a schematic diagram of the structure of an intelligent multifunctional railway disaster prevention and control rail vehicle in one embodiment of the present invention. The intelligent multifunctional railway disaster prevention and control rail vehicle includes a rail vehicle 1, a contact line anti-icing module 2, a snow removal module 3, and a snow melting module 4. Among them, the rail vehicle 1 selects a power supply operation vehicle or a contact network operation vehicle as a multifunctional disaster prevention and control carrier, which is suitable for railways and rail transit main lines; the contact line anti-icing module 2 is arranged on the top of the rail vehicle 1, and is used to detect whether the contact line is frozen and to strike the ice to separate it from the contact line. The contact line anti-icing module 2 can be raised and lowered. When the contact line is frozen, it rises and abuts against the contact network line. As the rail vehicle 1 travels along the track, the contact network is de-iced; the snow removal module 3 is arranged at the bottom of the front of the rail vehicle 1, and is used to push and shovel snow on the track, and to clear the snow accumulated in the track. The snow-removing module 3 can synchronously shovel and then sweep the snow on the track during the travel of the rail vehicle 1 to remove the snow. The snow-melting module 4 is arranged at the bottom of the rear of the rail vehicle 1 to generate heat to melt the snow. It can be used in two situations. After the snow-removing module 3 shovels and sweeps the snow, there will still be some snow left on the track. At this time, the snow-melting module 4 can accelerate the melting and cleaning of the residual snow. In addition, in another case, for key parts such as switches, centralized hot melting treatment can be adopted, which not only has a synergistic effect with the entire snow removal and disaster prevention, but also can play a targeted role in the key links.

[0022] It can be understood that during the travel of the rail vehicle 1, snow shoveling, snow sweeping and snow melting are performed on the track, and the contact line is de-iced at the same time. In the process of traveling along the track, the entire railway line can be comprehensively dealt with in the event of ice and snow disasters. Moreover, with the cooperation of snow shoveling, snow sweeping and snow melting, the accumulated snow on the track can be effectively cleared, avoiding the waste of resources caused by multiple dispatches.

[0023] In one embodiment, see Figure 1 and Figure 2 , also includes a cold laser module 5, which is arranged on the top of the rail car 1 and is used for cold laser cleaning of the contact line, and the contact line anti-icing module 2 includes an icing judgment mechanism 21, a mechanical deicing mechanism 22 and an anti-icing mechanism 23, and the icing judgment mechanism 21, the mechanical deicing mechanism 22 and the anti-icing mechanism 23 are arranged in sequence from front to back along the length direction of the rail car 1, and are respectively used to identify whether the contact line is frozen, de-ice and apply anti-icing grease, and the anti-icing mechanism 23 is arranged between the cold laser module 5 and the mechanical deicing mechanism 22, and is used for judging, deicing and cold laser cleaning, and then applying grease to prevent icing. Cold laser cleaning can clean foreign matter on the contact network. By using the high precision and directional energy concentration characteristics of the laser, it can safely remove floating foreign matter attached to the contact network without damaging the contact network structure itself. After cleaning, the surface of the contact network is cleaner and easier to adhere to grease, and the problem of uncleaned contact line foreign matter being more difficult to fall off after grease is applied is avoided.

[0024] It should be noted that the cold laser module 5 uses a laser device that generates cold laser, which is an existing mature device and is mainly used to clean foreign matter on the contact line.

[0025] In this embodiment, the icing judgment mechanism 21 can adopt a laser line diameter ice thickness measurement system, which uses the condition that the laser emitted by the I-shaped laser transmitter is blocked, that is, the laser condition received by the laser receiving panel to determine whether the contact line is frozen, and verifies it through a resistance ice thickness verification system to improve the accuracy of the judgment, that is, using a structure similar to a double pantograph and the contact line to form an electrical circuit, and verifies the icing condition through the output of a resistor, that is, an open circuit indicates ice has formed.

[0026] Furthermore, in order to mechanically de-ice the contact line, the mechanical de-icing mechanism 22 uses non-metallic strips to ensure that the striking force is moderate, which can effectively break the ice without damaging the contact line; the power can be selected from efficient and reliable electric motors to drive the non-metallic strips to ensure continuous output of sufficient power, and brushless DC motors can be used because of their low noise, high efficiency and low maintenance cost. Adjustable striking frequency and strength are adopted to adapt to ice layers of different thicknesses; and sensors can be integrated to monitor the thickness of the ice layer and automatically adjust the striking intensity to avoid invalid striking or excessive striking. It can also be used in conjunction with a visual system and a radar sensor to assist in locating the position of ice blocks, thereby achieving the purpose of precise striking.

[0027] It can be understood that the non-metallic strip can use nylon or polytetrafluoroethylene as the striking element, which is both wear-resistant and not easy to damage the contact line.

[0028] Furthermore, the anti-icing mechanism 23 is designed with a contact plate with capillary pores on the surface, and grease seeps out on the surface of the contact plate under a certain pressure; the contact plate is designed with a carbon slide plate on the pantograph to press against the contact network from below, so that the contact network can have its surface smeared with grease during the friction with the contact plate; a well-sealed container is used to store special grease, and is equipped with a pressure pump and a filtering device to ensure a smooth supply of grease and not be affected by the external environment; the grease is collected into the oil pump through a filtering circuit, and the grease can be reused after proper filtration, which not only avoids material waste but also ensures the increase of effective load.

[0029] It can be understood that the contact plate can use foam copper or foam graphite as the plate material.

[0030] In one embodiment, see Figure 2 The snow removal module 3 includes a snow scraper 31 and a roller snow sweeper 32. The snow scraper 31 is arranged on the front of the rail vehicle 1, and the roller snow sweeper 32 is arranged at the bottom of the front of the rail vehicle 1 for rolling snow sweeping, first shoveling snow and then sweeping snow.

[0031] The roller snow sweeping device 32 includes an arc plate 321, a roller 322 and a lifting mechanism 323. The lifting mechanism 323 is installed at the bottom of the rail vehicle 1, and its movable end is connected to the arc plate 321, and is used to lift and lower the arc plate 321. The roller 322 is rotatably connected to the inner side of the arc plate 321, and is used to roll and sweep the snow. The arc plate 321 has a secondary snow shoveling function, and the snow swept by the roller 322 is discharged to both sides of the track. The outer side of the roller 322 is provided with a plurality of ridges 301 distributed in a circular pattern, and gullies are formed between the ridges 301, which makes it easier to carry away the accumulated snow. In addition, a plurality of brush wires 302 are provided on the ridges 301, and are staggered and stacked. Specifically, the roller 322 can be used to sweep the snow. Figure 3 and Figure 4 The brush wires 302 are staggered and arched in an arc shape, with gaps formed between them, and can be compressed, so that the track can be brushed with strong adhesion to improve the snow-clearing effect, and a rubber scraper 303 is provided at the bottom of the arc plate 321. After brushing, the rubber scraper 303 is adhered to the track for cleaning again.

[0032] It can be understood that the lifting has three position states. The first position state is that neither the roller 322 nor the rubber scraper 303 is in contact with the track, which is a non-working position state; the second position state is that the roller 322 is in contact with the track, and the brush wire 302 is in a lightly squeezed state, which is used for cleaning under high-speed stroke state; the third position state is that the brush wire 302 is further squeezed, and the rubber scraper 303 is in contact with the track, which is used for detailed cleaning under low-speed stroke state.

[0033] Furthermore, the brush wire 302 may be a mixed material of steel wire and plastic or nylon brush wire, which can reduce direct impact and wear on the track while ensuring the cleaning effect. Nylon or plastic brush wire is relatively soft and can effectively reduce scratches on the track surface. The brush wire 302 can also be made of flexible material, such as synthetic materials with high wear resistance and low hardness. These materials can reduce damage to the track surface while maintaining sufficient strength.

[0034] It can be understood that the lifting mechanism 323 can use a screw guide pair, a hydraulic push rod or a pneumatic push rod and other structural parts with lifting functions to achieve the purpose of lifting and lowering the roller 322 and the arc plate 321.

[0035] In one embodiment, see Figure 1 , Figure 2 and Figure 5 The snow melting module 4 includes a baffle 41 and a hot air component 42. The baffle 41 is arranged at the bottom of the rail vehicle 1, and the hot air component 42 is arranged on the baffle 41. The baffle 41 provides a snow shoveling function at the rear of the vehicle to shovel the remaining snow and discharge it to both sides.

[0036] Specifically, the hot air assembly 42 includes a hot air blower 421 and a purge guide nozzle 422. The hot air blower 421 is installed on the baffle 41, and the purge guide nozzle 422 is arranged at the air outlet of the hot air blower 421. The hot air blower 421 blows hot air, which is guided by the purge guide nozzle 422 and blows to the corresponding position where snow needs to be melted. There are two hot air blowers 421, which are distributed on the left and right. Correspondingly, one hot air blower 421 is installed with one purge guide nozzle 422.

[0037] Furthermore, the purge guide nozzle 422 is connected to the air outlet of the hot air blower 421 through a swinging mechanism 423, and the swinging mechanism 423 is used to drive the lateral reciprocating swing of the purge guide nozzle 422, and the swinging direction has an angle with the central axis of the rail vehicle 1 to form a swinging sweeping area 401, and the two hot air blowers 421 form two front and rear swinging sweeping areas 401, forming a double hot melting coverage area, and the baffle 41 is connected to the rail vehicle 1 through an angle adjustment mechanism 424, and the angle adjustment mechanism 424 is used to drive the baffle 41 to rotate horizontally, driving the hot air blower 421, the swinging mechanism 423 and the purge guide nozzle 422 to rotate together, forming a hot melting coverage area 402, thereby expanding the range of hot melting coverage and being able to melt snow on the track in an expanded range.

[0038] It can be understood that with the establishment of the swing mechanism 423 and the angle adjustment mechanism 424, the hot melt air outlet position can be fixed and move along the rails, or it can swing in double rows to sweep the hot melt, or it can rotate to cover a large area of ​​hot melt.

[0039] It should be noted that the swing mechanism 423 can adopt a motor, which is installed on the outside of the hot air blower 421, and the output shaft is connected to the purge guide nozzle 422. In addition, the purge guide nozzle 422 is connected and communicated with the air outlet of the hot air blower 421 through an elastic sleeve, and the power motor drives the purge guide nozzle 422 to seal the air supply when it swings and provides the mobility of the purge guide nozzle 422 to swing; the angle adjustment mechanism 424 can adopt a hydraulic push rod, and a frame is fixed at the bottom of the rail car 1, and the baffle 41 is hinged to the frame, and the two ends of the hydraulic push rod are respectively hinged to the frame and the baffle 41. Under the telescopic action, the baffle 41 can be driven to rotate, and the angle adjustment mechanism 424 can also be directly driven by a motor to achieve the purpose of rotation adjustment.

[0040] In one embodiment, see Figure 1 and Figure 2 , and also includes a magnetic suction module 6, which is arranged at the bottom of the rail car 1 and is used to magnetically absorb magnetic foreign objects on the track bed.

[0041] Specifically, the magnetic suction module 6 includes a conveyor belt 61, a magnet block 62 and a receiving tray 63. Several magnet blocks 62 are equidistantly arranged on the conveyor belt 61. The receiving tray 63 is set at the bottom of the conveyor belt 61. The conveyor belt 61 is powered on and the magnet blocks 62 follow the conveyor belt 61. A DC power supply is connected to the front side of the conveyor belt 61. The magnet blocks 62 work to absorb the roadbed garbage. When they run to the receiving tray 63, the power supply of the magnet blocks 62 is disconnected, and the garbage automatically falls into the receiving tray 63.

[0042] In order to better understand the present invention, the following Figures 1 to 5 The technical solution of the present invention is described in detail: during the travel of the rail vehicle 1, the snow scraper 31 shovels the accumulated snow to both sides of the track, and the roller snow sweeper 32 sweeps up the snow that has not been shoveled away, and the roller 322 and the brush wire 302 on the roller 322 are in contact with the track to sweep up the accumulated snow and push it to both sides of the track; and the blowing guide nozzle 422 is moved by the swing mechanism 423 and the angle adjustment mechanism 424 to form a covering hot melt on the track; during travel, it also cooperates with the magnetic suction module 6 and the contact line anti-icing module 2 to simultaneously clean the magnetic debris on the track and the ice on the contact line. Under the cleaning of the contact line anti-icing, it cooperates with the cold laser module 5 to clean the debris on the contact line, and the anti-icing mechanism 23 is used to apply anti-icing grease to form a set of actions of deicing, de-impurity and anti-icing, thereby improving the maintenance of the contact line and the deicing and anti-icing effects.

[0043] The specific implementation of the present invention described above does not constitute a limitation on the protection scope of the present invention.
