Description

Technical Field

[0001] The invention relates to the technical field of train conductive deicing, in particular to a mechanical composite current collector shoe slide plate. Background Art

[0002] The collector shoe skateboard directly contacts the contact network, draws electricity from the contact network, and transmits the electricity to the train for the train to use. As a key core component of the train, the material selection and installation of the collector shoe skateboard directly affect the safety and efficiency of the train operation. At present, the mainstream material of the collector shoe skateboard is metal-impregnated carbon material. In rainy and snowy cold weather, the contact network conductive rails exposed to the road surface are prone to ice. The hardness of ice is greater than the hardness of the carbon skateboard itself. After the two collide, the carbon skateboard is easily damaged and the corners are lost, resulting in abnormal ignition, which in turn causes a series of unsafe accidents such as train suspension. Moreover, it is impossible to actively de-ice, and it is impossible to quickly transfer internal heat to both sides, resulting in very limited active de-icing effects. Summary of the invention

[0003] The technical problem to be solved by the present invention is: the current mainstream material of the collector shoe skateboard is metal-impregnated carbon material, which leads to abnormal ignition, thus causing a series of unsafe accidents such as train shutdowns; and it is impossible to actively de-ice, nor can it quickly transport internal heat to both sides, resulting in very limited active de-icing effect.

[0008] The deicing unit is provided with a lateral heat exchange flow channel for connecting the ice scraping groove, the upper mounting blind hole and the built-in guide chamber.

[0009] The lateral heat exchange flow channel is located inside the ice scraping groove and has a built-in guide vane fixed inside the air outlet.

[0010] The inner width of the ice scraping groove gradually narrows from the inside to the outside.

[0011] The lateral heat exchange flow channel comprises two horizontally arranged lateral heat exchange flow channels and an obliquely arranged connecting flow channel.

[0012] An arc-shaped expansion opening is provided at the air inlet position of the bottom-mounted through-groove.

[0013] The inner angles on both sides of the ice scraping groove are both processed by arc chamfering.

[0019] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0020] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0021] Figure 1 , Figure 2 and Figure 3 A mechanical composite collector shoe skateboard is shown, comprising a deicing unit 1 supported by a copper-based powder metallurgy material, wherein ice scraping slopes are arranged on both sides of the upper end of the deicing unit 1, and ice scraping grooves 2 are arranged on the deicing unit 1 at the position of the ice scraping slopes, a through hole 3 connecting the upper and lower ends is arranged inside the deicing unit 1, an upper mounting blind hole 5 with a graphite column 4 installed inside is arranged on the upper surface of the deicing unit 1, an air vent 6 is arranged on the inner bottom surface of the upper mounting blind hole 5, and a linkage internal guide unit 7 is arranged inside the deicing unit 1 at the position of the through hole 6.

[0022] Working principle: When the train runs at high speed, wind pressure is generated at the top de-icing unit 1, and then the linked internal guide unit 7 inside it is driven. The air drawn into the through hole 3 is then introduced into the de-icing unit 1 by the linked internal guide unit 7, and then guided through the outside of the graphite column 4, the heat generated by the graphite column 4 is quickly introduced into the ice scraping groove 2, and then the accumulated ice inside is quickly melted and blown outward, thereby improving the main body self-de-icing effect of the equipment.

[0023] In order to cooperate with the lateral screw fixation, a screw groove 8 for cooperating installation is opened on the inner bottom surface of the ice scraper groove 2.

[0024] In order to cooperate with the utilization of wind pressure when the train runs at high speed, a bottom through groove 9 is opened on the lower surface of the de-icing unit 1, and a side assembly groove for installing a linked internal guide unit 7 is opened on the inner side of the bottom through groove 9. A built-in guide chamber connected to the through hole 6 is opened inside the de-icing unit 1 above the side assembly groove.

[0025] When the train runs at high speed, the generated wind pressure is introduced from the bottom-mounted penetrating grass 9, and then the linkage internal guide unit 7 is driven and controlled.

[0026] In order to cooperate with the active control of the flow guide, the linked internal flow guide unit 7 includes a synchronous control shaft 71 movably installed between the lateral assembly groove and the built-in flow guide chamber, a wind-driven blade 72 axially fixed at the lower end of the synchronous control shaft 71, and an upper guide blade 73 axially fixed at the upper end of the synchronous control shaft 71.

[0027] In order to conduct rapid flow diversion and heat exchange inside, a lateral heat exchange flow channel for connecting the ice scraping groove 2, the upper mounting blind hole 5 and the built-in flow diversion chamber is provided inside the deicing unit 1.

[0028] The deicing unit 1 adopts a split structure design, which is convenient for the production and processing of the lateral heat exchange flow channel.

[0029] In order to guide the opening, a built-in guide vane 10 is fixed inside the air outlet of the lateral heat exchange flow channel located inside the ice scraping groove 2.

[0030] The built-in guide vanes 10 guide the high-pressure air of the lateral heat exchange flow channel opening to the inner bottom surface and the inner walls on both sides of the ice scraping groove 2, thereby quickly separating the accumulated ice adhered to the inner wall of the ice scraping groove 2.

[0031] In order to achieve the inner flow guiding effect, the inner width of the ice scraping groove 2 gradually narrows from the inside to the outside.

[0032] In order to coordinate flow guidance and interconnection, the lateral heat exchange flow channel includes two horizontally arranged side replacement heat flow channels 11 and an inclined connecting flow channel 12 .

[0033] The side replacement hot runner 11 is connected to the built-in guide chamber, and the oblique connecting flow channel 12 is connected to the ice scraping groove 2.

[0034] When the wind-driven blades 72 drive the synchronous control shaft 71 and the upper guide blades 73 to rotate at high speed, the upper guide blades 73 draw air from the air vents 6 into the built-in guide chamber, and then blow it into the heat exchange flow channel. When passing through the upper mounting blind hole 5, the heat of the graphite column 4 is quickly extracted, and then introduced into the ice scraping trough 2 through the inclined connecting flow channel 12 to melt and remove the accumulated ice inside the ice scraping trough 2.

[0035] In order to improve the flow guiding effect, an arc-shaped expansion opening is provided at the air inlet position of the bottom through groove 9.

[0036] By increasing the intake air volume and reducing the resistance, the driving efficiency of the wind-driven blades 72 is improved.

[0037] In order to facilitate the inner flow diversion and assembly, the inner angles on both sides of the ice scraper groove 2 are both chamfered with arcs.

[0038] Based on the above ideal embodiments of the present invention, the relevant staff can make various changes and modifications without departing from the technical concept of the present invention through the above description. The technical scope of the present invention is not limited to the contents of the specification, and its technical scope must be determined according to the scope of the claims.
