Description

Technical Field

[0001] The utility model relates to the technical field of coating operations, in particular to a double superphobic material coating device for railway contact networks. Background Art

[0002] The overhead contact network is a high-voltage transmission line that is erected in a zigzag shape above the rails in an electrified railway and is used by the pantograph to draw current. Since the overhead contact network is set up in the open air, it is easily affected by extreme weather such as rain, snow, and freezing. At present, the de-icing and anti-icing technologies at home and abroad are mainly divided into three categories: thermal ice melting method, mechanical ice breaking method and coating material method. Among them, the coating material method is to coat the surface of the overhead contact network cable with antifreeze. The antifreeze can be made of double super-repellent anti-icing material, which can prevent the surface from being covered and crystallized by ice. It can prevent disasters economically and effectively and is very easily accepted by rail transit companies.

[0003] After searching, it was found that the Chinese invention patent application with the publication number CN115155939A discloses a contact network antifreeze liquid coating device, including a base connected to an external mobile vehicle, a box body arranged above the base, a cleaning roller group and a coating roller arranged in the box body, a cleaning motor driving the cleaning roller group, and a transmission mechanism for transmitting the power of the cleaning motor in the cleaning roller group and between the cleaning motor and the coating roller. Its working principle is: the cleaning motor drives the cleaning roller group to rotate to clean the surface of the contact network cable, and then the coating roller rotates to absorb the antifreeze liquid inside the box body and coat the lower surface of the contact network cable. However, this technical solution has the following problems: as the coating roller continuously absorbs the antifreeze liquid inside the box body, the antifreeze liquid level inside the box body will drop, which causes the antifreeze liquid to change the infiltration height of the coating roller, affecting the coating roller's adsorption effect on the antifreeze liquid during the rotation process.

DETAILED DESCRIPTION

[0037] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0038] See also Figure 1-Figure 4 The utility model provides a technical solution: a double superphobic material coating device for railway contact network, comprising: a box body 1 with a liquid storage tank 4; a coating roller 9 rotatably connected to the box body 1; in this embodiment, a partition 2 is arranged in the box body 1, and the partition 2 divides the interior of the box body 1 into a dirt storage tank 3 and a liquid storage tank 4, wherein the dirt storage tank 3 is located at the front end of the liquid storage tank 4, and a cleaning roller 6 is arranged above the dirt storage tank 3;

[0039] The above technical solution can be used to clean and coat the contact network cables. Since the contact network cables are usually installed in the open air, a large amount of dust accumulates on their surfaces. If they are not cleaned, the coating of antifreeze will be affected. Specifically, when in use, the box 1 is installed on a mobile vehicle to ensure that the cleaning roller 6 and the coating roller 9 are in contact with the bottom of the contact network cable. The contact network cable moves with the vehicle. The cleaning roller 6 cleans the contact network cable, and the dust falls into the dirt storage tank 3. The coating roller 9 coats the contact network cable with antifreeze. In addition, since the laid contact network is generally located at a high place and the contact network cables are intricate, they are often provided with components such as clamps for connection and fixation, making it difficult to coat 100%. Usually, only the lower end of the cable is coated during coating. The thickness of the liquid storage coating of the coating roller 9 is at least twice the diameter of the cable to facilitate deformation and coating of the coating. The maximum coating rate of the cable can reach 75%, covering the lower half of the cable, which can avoid the appearance of hanging icicles and reduce most of the freezing.

[0040] like Figure 2 As shown, the dual superphobic material coating device for the railway contact network also includes a driving component, which is used to drive the coating roller 9 to rotate and absorb the antifreeze in the liquid storage tank 4, so that the antifreeze on the surface of the coating roller 9 is coated on the lower end of the contact network cable; in this embodiment, the driving component includes: a motor 5 arranged on the side wall of the box body 1, whose output shaft is connected to one end shaft of the cleaning roller 6; a belt pulley 7, which has two, one of which is arranged on the other end shaft of the cleaning roller 6, and the other is arranged on the end shaft of the coating roller 9, and a belt 8 for driving the cleaning roller 6 and the coating roller 9 is arranged between the belt pulleys 7;

[0041] The above technical solution can drive the cleaning roller 6 and the coating roller 9 to rotate. Specifically, when in use, the cleaning roller 6 is driven to rotate by the motor 5, and the cleaning roller 6 cleans the surface of the contact network cable. The coating roller 9 is driven to rotate by the motor 5 in conjunction with the belt pulley 7 and the belt 8. The coating roller 9 rotates and the antifreeze liquid in the liquid storage tank 4 is coated on the lower surface of the contact network cable, covering the lower half of the cable, which can avoid the appearance of hanging ice and thus reduce most of the freezing.

[0042] like Figure 3 As shown, the dual superphobic material coating device for the railway contact network also includes: a push plate 11 that matches the shape of the liquid storage tank 4 and is arranged at the bottom of the liquid storage tank 4; a lifting component, which is used to drive the push plate 11 to move up and down to change the liquid level of the antifreeze liquid in the liquid storage tank 4; in this embodiment, the lifting component includes an electric push rod 10 whose bottom is fixed to the inside of the box 1, and the output end of the electric push rod 10 is connected to the bottom of the push plate 11;

[0043] The adoption of the above technical solution can ensure that the antifreeze liquid can fully contact the coating roller 9. With long-term use, the antifreeze liquid level in the liquid storage tank 4 will drop. At this time, the electric push rod 10 drives the push plate 11 to rise, thereby restoring the antifreeze liquid level to the initial position. At this time, the antifreeze liquid infiltration height H of the lower part of the coating roller 9 reaches a preset value, thereby realizing real-time adjustment of the antifreeze liquid level in the liquid storage tank 4. The antifreeze liquid infiltration height of the lower part of the coating roller 9 is at least equal to half of the cable diameter, so that during the rotation of the coating roller 9, the coating roller 9 can fully absorb the antifreeze liquid, and when the coating roller 9 is deformed to cover the cable for coating, the surface of the coating roller 9 still has sufficient liquid humidity to infiltrate the coating cable.

[0044] Further, such as Figure 3 As shown, a sealing ring 12 is provided at the outer edge of the push plate 11;

[0045] The above technical solution can ensure that the push plate 11 and the inner wall of the liquid storage tank 4 are seamlessly fitted together, preventing the antifreeze liquid from leaking from the gap between the push plate 11 and the inner wall of the liquid storage tank 4, thereby avoiding waste.

[0046] like Figure 4As shown, a detection component is used to detect the infiltration height H of the antifreeze liquid on the lower part of the coating roller 9 in real time, so as to ensure that when the height H is lower than a preset value, the push plate 11 is driven to rise by the lifting component, so as to raise the liquid level of the antifreeze liquid in the liquid storage tank 4 to the height H that fully infiltrates the lower part of the coating roller 9; in this embodiment, the preset value of the height H is at least equal to half of the cable diameter, and the detection component includes: a bracket 13; a rotating plate 14 rotatably arranged on the bracket 13; a floating plate 15, which is arranged at one end of the rotating plate 14, and the floating plate 15 is in contact with the antifreeze liquid; a switch 16 arranged on the bracket 13, and the switch 16 is used to control the lifting component. In normal state, the liquid level in the liquid storage tank 4 pushes the floating plate 15 to float, so that one end of the rotating plate 14 remains in contact with the switch 16; when the liquid level drops, the floating plate 15 drops, and one end of the rotating plate 14 tilts up and loses contact with the switch 16, and the switch 16 controls the lifting component to drive the push plate 11 to rise;

[0047] The above technical solution can realize automatic real-time adjustment of the liquid level of the antifreeze liquid. When the liquid level of the antifreeze liquid in the liquid storage tank 4 drops, the antifreeze liquid infiltration height H of the lower part of the coating roller 9 is lower than the preset value, the floating plate 15 drops, and one end of the rotating plate 14 is tilted and out of contact with the switch 16. The switch 16 controls the electric push rod 10 to drive the push plate 11 to rise, thereby restoring the liquid level of the antifreeze liquid to the initial position. At this time, the infiltration height H of the antifreeze liquid on the lower part of the coating roller 9 reaches the preset value, thereby realizing real-time adjustment of the liquid level of the antifreeze liquid in the liquid storage tank 4. It should be noted that since the coating roller 9 will contact the antifreeze liquid in the liquid storage tank 4 during the rotation process, the liquid level of the antifreeze liquid is not constant, but fluctuates within a certain range. Only when the floating plate 15 cannot be reset within a period of time, causing the rotating plate 14 to not contact the switch 16 for a period of time, at this time, the switch 16 starts the electric push rod 10 to drive the push plate 11 to rise. Therefore, the switch 16 is preferably a delay switch.

[0048] Further, such as Figure 4 As shown, the double superphobic material coating device for the railway contact network also includes: a slider 17, which is connected to the bracket 13; a slide rail 18 slidably matched with the slider 17; a threaded rod 19 rotatably arranged in the slide rail 18, and the threaded rod 19 is threadedly matched with a thread groove 20 provided in the slider 17; a scale 21 is arranged on the side of the slide rail 18, and the bracket 13 is connected to an indicator plate 22;

[0049] The above technical solution can be used to adjust the preset value of the wetting height H according to the contact network cables of different thicknesses, thereby improving the application scope of the device. When the preset value of the wetting height H needs to be adjusted, the slider 17 can be driven to slide in the slide rail 18 by rotating the threaded rod 19, thereby driving the bracket 13 to rise and fall, and the bracket 13 drives the floating plate 15 to rise and fall synchronously. When the floating plate 15 rises, the preset value of the wetting height H is increased. Conversely, when the floating plate 15 falls, the preset value of the wetting height H is reduced, thereby adjusting the preset value of the wetting height H according to the contact network cables of different thicknesses.

[0050] Further, such as Figure 4 As shown, a bolt hole 23 is provided on the outside of the slide rail 18, and a bolt 24 is provided in the bolt hole 23;

[0051] By adopting the above technical solution, the slide rail 18 can be fixedly installed on the inner wall of the liquid storage tank 4 by means of the bolts 24 .

[0052] Working principle: when in use, first install the box 1 on a mobile vehicle, ensure that the cleaning roller 6 and the coating roller 9 are in contact with the bottom of the contact network cable, and move along the contact network cable with the vehicle to clean and apply antifreeze, and drive the cleaning roller 6 to rotate through the motor 5, and the cleaning roller 6 cleans the surface of the contact network cable, and the dust falls into the dirt storage tank 3 for collection, and then the motor 5 cooperates with the belt pulley 7 and the belt 8 to drive the coating roller 9 to rotate, and the coating roller 9 rotates. The antifreeze in the liquid storage tank 4 is coated on the lower surface of the contact network cable, covering the lower half of the cable, which can avoid the appearance of hanging ice, thereby reducing most of the freezing;

[0053] As the antifreeze is continuously consumed by the coating roller 9, when the antifreeze level in the liquid storage tank 4 drops and the antifreeze wetting height H of the lower part of the coating roller 9 is lower than a preset value, the floating plate 15 drops, and one end of the rotating plate 14 tilts up and disengages from the switch 16. The switch 16 controls the electric push rod 10 to drive the push plate 11 to rise, thereby restoring the antifreeze level to the initial position. At this time, the antifreeze wetting height H of the lower part of the coating roller 9 reaches a preset value, thereby achieving real-time adjustment of the antifreeze level in the liquid storage tank 4. The antifreeze wetting height of the lower part of the coating roller 9 is at least equal to half of the cable diameter, so that during the rotation of the coating roller 9, the coating roller 9 fully absorbs the antifreeze, and when the coating roller 9 deforms to cover the cable for coating, the surface of the coating roller 9 still has sufficient liquid humidity to wet the cable;

[0054] When the preset value of the wetting height H needs to be adjusted, the slider 17 can be driven to slide in the slide rail 18 by rotating the threaded rod 19, thereby driving the bracket 13 to rise and fall, and the bracket 13 drives the floating plate 15 to rise and fall synchronously. When the floating plate 15 rises, the preset value of the wetting height H is increased. Conversely, when the floating plate 15 falls, the preset value of the wetting height H is reduced, thereby adjusting the preset value of the wetting height H according to the different thicknesses of the contact network cables.
