[0001] The invention belongs to the field of railway contact line deicing, and in particular relates to a railway contact line deicing system and a deicing method. Background Art

[0002] In cold areas, winter is often accompanied by low temperatures, snowfall, and freezing weather. As an important part of electrified railways, the railway contact network is easily affected by ice and snow. When the surface of the contact network is frozen, the weight of the contact network will increase, causing the sag of the contact network to change, affecting the normal operation of the contact network. In addition, the ice layer will also reduce the conductivity of the contact network and increase the resistance of the contact network, thereby affecting the current collection quality of the electric locomotive, and may even cause the electric locomotive to fail to operate normally. Therefore, in order to ensure the safe operation of electrified railways in winter, it is necessary to develop effective contact network deicing technology. The icing of the contact network will not only affect the efficiency of railway transportation, but also pose a serious threat to the safety of railway transportation. If the contact network is severely frozen, it may cause accidents such as contact network disconnection and network collapse, thereby affecting the normal order of railway transportation, and may even cause casualties and property losses. Therefore, in order to ensure the safety of railway transportation, it is necessary to develop reliable contact network deicing technology.

For example, drone technology, laser technology, thermal deicing technology, etc. These technologies and equipment can effectively improve the efficiency and safety of contact network deicing. In addition, with the development of intelligent technology, intelligent technology can also be applied to contact network deicing projects to realize the automation and intelligence of contact network deicing and improve the efficiency and quality of contact network deicing. With the rapid development of the economy, the demand for railway transportation is increasing. In order to meet the needs of railway transportation, it is necessary to improve the efficiency and safety of railway transportation. The research and development of contact network deicing projects can effectively improve the operating efficiency and safety of electrified railways in winter, thereby meeting the needs of railway transportation. In addition, the research and development of contact network deicing projects can also reduce the cost of railway transportation and improve the economic benefits of railway transportation.

[0036] The present invention is further described in detail below in conjunction with embodiments and drawings, but the embodiments of the present invention are not limited thereto.

[0037] See also Figure 1-Figure 11 The railway contact wire deicing system of the present invention comprises a chassis 1, a power supply system arranged on the chassis 1, a deicing system, and a lifting device 2 for driving the power supply system and the deicing system to rise and fall synchronously, wherein:

[0038] The chassis 1 is composed of an aluminum frame and fixing screws, and can be used in conjunction with a specific fixing bracket installed on the roof of a locomotive to fix the railway contact wire deicing system of the present invention on the roof of the locomotive;

[0039] The deicing system comprises a frame 3, a heating device 4, an air blowing device 5 and an ice scraping device which are sequentially arranged on the frame 3, wherein:

[0040] The heating device 4 is used to melt the ice on the contact line. The heating device 4 can adopt an existing heating module on the market. When the contact line is de-iced, the heating module contacts the contact line, thereby causing the ice on the contact line to melt.

[0041] The blowing device 5 is connected to an air pump 13 installed on the base frame 1. The air pump 13 is used to provide high-pressure gas to the blowing device 5. The blowing device 5 sprays high-pressure gas to blow away the condensation nuclei on the contact network to prevent ice cubes from recondensing. The blowing device 5 is arranged at the rear side of the heating device 4 and is composed of a jet module, which can spray high-pressure gas upwards.

[0042] The ice scraping device is used to scrape the residual ice on the contact line after it melts;

[0043] The power supply system is located behind the deicing system and is used to supply power from the deiced contact wires for the operation of various functional modules. The power supply system includes a power supply device 8 and a power distribution master control device.

[0044] See also Figure 1-Figure 11, a sensor positioning device is provided at the front end of the frame 3 (i.e., the end close to the heating device 4), and in addition, the lifting frame 201 is also provided with a sensor positioning device at a corresponding position at the end of the frame 3; the sensor positioning device is used to obtain the position of the contact line to be de-iced, and the sensor positioning device includes a sensor 12 and a camera 11 arranged on the left and right sides of the frame 3;

[0045] Through the above settings, the position of the contact line is automatically captured by the sensor 12, and the position of the contact line can be manually checked by the camera 11. When the contact line position information detected by the sensor 12 is consistent with the contact line position information detected manually, that is, the controller adjusts the position of the de-icing system according to the contact line position information detected by the sensor 12, the staff detects that the position of the de-icing system is correct through the camera 11 (that is, when the contact line is within the working range of the de-icing system), and the staff does not participate in the adjustment of the de-icing system at this time. Only when the staff detects that the position of the de-icing system has an error through the camera 11, the staff manually assists in adjusting the position of the de-icing system. At the same time, the present invention can also adopt a design of manual monitoring as the main and sensor positioning as the auxiliary. The position of the de-icing system can be timely monitored and adjusted through the sensor positioning device and the longitudinal drive mechanism 10 (and the lifting device 2) during work, so as to avoid the position of the de-icing system from being offset, thereby easily coping with the "Z"-shaped distribution structure of the contact network.

[0046] See also Figure 1-Figure 11 The lifting device 2 includes a lifting frame 201 and a lifting drive mechanism for driving the lifting frame 201 to lift, wherein the frame 3 is installed on the lifting frame 201; the lifting drive mechanism includes a jack 202 and a lifting motor 204 for driving the jack 202 to work, wherein the jacks 202 are divided into two groups, and the two groups of jacks 202 are symmetrically arranged on the front and rear sides of the base frame 1, and each group of jacks 202 has two jacks, and the two jacks 202 are symmetrically arranged on the left and right sides of the base frame 1; the two jacks 202 in each group are connected by a connecting shaft 203; the lifting motor 204 is divided into two groups, and the two groups of lifting motors 204 respectively drive the two connecting shafts 203 to rotate, thereby driving the corresponding two jacks 202 to work, thereby driving the lifting frame 201 to lift;

[0047] In addition, in order to ensure the lifting accuracy, a lifting guide mechanism is arranged between the front and rear sides of the lifting frame 201 and the base frame 1, and the lifting guide mechanism includes a guide rod arranged on the lifting frame 201 and a guide hole arranged on the base frame 1 and matched with the guide rod.

[0048] See also Figure 1-Figure 11A longitudinal driving mechanism 10 for driving the frame 3 to move longitudinally (i.e., left and right) is arranged between the frame 3 and the lifting frame 201. The longitudinal driving mechanism 10 includes electric slide rails arranged on the front and rear sides of the lifting frame 201, and the frame 3 is installed on the driving end of the electric slide rails; the electric slide rails are used to drive the frame 3 and the de-icing system arranged on the frame 3 to move left and right, thereby adjusting the left and right position of the de-icing system, so as to achieve de-icing of the contact line.

[0049] See also Figure 1-Figure 11 The ice scraping device comprises a first ice scraping mechanism 6 for scraping off residual ice on the left and right sides of the contact line and a second ice scraping mechanism 7 for scraping off residual ice on the lower side of the contact line, wherein:

[0050] The first ice scraping mechanism 6 includes a first bracket 601 and first ice scraping assemblies arranged on the left and right sides of the first bracket 601, wherein the contact line passes between the first ice scraping assemblies on the left and right sides; the first ice scraping assemblies on each side include multiple groups of vertically arranged first reamers 602, the upper ends of the multiple groups of first reamers 602 are all installed on the upper end of the first bracket 601, and the lower ends are installed on the lower end of the first bracket 601;

[0051] The second ice scraping mechanism 7 includes a second bracket 701 and a second ice scraping assembly arranged on the second bracket 701, wherein the contact line is located above the second ice scraping assembly; the second ice scraping assembly includes multiple groups of transversely arranged second reamers 702, and the two ends of the multiple groups of second reamers 702 are respectively installed on the left and right sides of the second bracket 701.

[0052] Through the above arrangement, the contact line passes through the heating device 4 and the blowing device 5 in sequence and then enters the first ice scraping mechanism 6. The first reamer 602 located on both sides of the first ice scraping mechanism 6 can scrape the residual ice on the left and right sides of the contact line (this can be achieved by driving the frame 3 and the deicing system on the frame 3 to move left and right through the electric slide rail or by controlling the spacing between the first reamer 602 on the left and right sides); after the residual ice on the left and right sides of the contact line are scraped, the bottom of the contact line will contact the second scraper in the second ice scraping mechanism 7 (for example, driven by the lifting device 2), thereby scraping the residual ice at the bottom of the contact line. In the above process, since the ice on the contact line is melted in advance, under the action of gravity, even if the melted ice recondenses again, it will recondense at the bottom of the contact line, so it is only necessary to scrape the residual ice at the bottom of the contact line through the second ice scraping mechanism 7.

[0053] In this embodiment, the number of reamers on the left and right sides of the first bracket 601 are three groups; the number of second reamers 702 on the second bracket 701 is also three groups.

The telescopic rod is extended or shortened by the electric push rod 806, thereby driving the swing rod 803 to swing, thereby driving the support frame 802 to swing upward or downward, so as to ensure that the pantograph 801 on the support frame 802 is in contact with the contact line after deicing, thereby completing power collection; the power collection device 8 draws power from the contact line and is processed by the power distribution master control device to provide power for the overall equipment operation.

[0060] See also Figure 1-Figure 11 The railway contact wire deicing method of the present invention comprises the following steps:

[0061] Step 1: The railway contact wire deicing system of the present invention is installed on the top of the locomotive, and the lifting device 2 drives the power supply system and the deicing system to rise, so that the pantograph 801 in the power supply device 8 contacts the contact wire, so that electricity can be taken from the contact wire, thereby realizing power supply to each functional module in the railway contact wire deicing system of the present invention;
