Description

Technical Field

[0001] The present invention relates to the technical field of railway track accessories, and particularly relates to a heat dissipation device for railway tracks. Background Art

[0002] Railway tracks are classified into ballasted tracks and ballastless tracks according to the track structure. Among them, a ballasted track is composed of rails, sleepers, ballast, etc., and the track is surrounded by crushed stones, which is usually also called a ballast bed track. A ballastless track uses an integral foundation such as concrete or asphalt mixture to replace the granular ballast bed. Due to the characteristics of good integrity, stable line, and small maintenance workload of the ballastless track, most high-speed trains use ballastless tracks. However, the overall track bed structure is relatively dense, and the heat dissipation path is mainly through the surface of the concrete or asphalt layer to dissipate heat to the air, with a relatively small heat dissipation area and a slow heat dissipation speed. Moreover, the specific heat capacity of concrete and asphalt is relatively large, and the temperature rises slowly after absorbing heat, but it will also release heat relatively slowly during heat dissipation, which is not conducive to rapid heat dissipation.

[0003] When a train passes through the railway track, the temperature of the railway track will rise. In summer when the temperature is high, within a short period of time, after multiple trains pass through the railway track, the temperature rise will be more obvious. To prevent the railway track from overheating and deforming, it is usually necessary for workers to sprinkle water on the railway track for cooling, which has problems such as large workload, uneven cooling, and low cooling efficiency.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present invention belongs. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0023] As Figures 1-5As shown, in an embodiment of a heat dissipation device for a railway track, the heat dissipation device includes a water storage tank 1, a heat dissipation element 2, a heat conduction assembly 3, a transmission assembly 4, an energy storage assembly 5, and a water pumping assembly 6. The water storage tank 1 is provided with a receiving space capable of accommodating water, and a through hole 12 communicating with the receiving space is opened on the top cover 11 of the water storage tank 1. The heat dissipation element 2 is placed on the top cover 11. The heat conduction assembly 3 includes a telescopic element 31 and a heat conduction block 32. The telescopic section of the telescopic element 31 is connected to the heat conduction block 32. A thermally expandable liquid is accommodated in the telescopic element 31 so as to be able to drive the telescopic section to drive the heat conduction block 32 to abut against the middle and lower parts of the railway track in summer. The end of the telescopic element 31 far from the heat conduction block 32 contacts the heat dissipation element 2. The transmission assembly 4 includes a first transmission module and two fans 43. The two fans 43 are arranged at opposite ends of the first transmission module. The fans 43 are used to rotate when receiving the wind generated when a train passes by, and drive the first transmission module to move. The energy storage assembly 5 has a receiving part for receiving power and an output part for outputting power. The receiving part is connected to the first transmission module. The movement of the first transmission module can store energy in the energy storage assembly 5. The water pumping assembly 6 is in transmission connection with the output part. The water pumping assembly 6 is used to be driven to guide the water in the receiving space onto the heat dissipation element 2 when the energy storage mechanism releases the stored energy.

[0024] In this embodiment, when the temperature is relatively high in summer, on the one hand, the liquid inside the telescopic element 31 expands due to heat, pushing the heat conduction block 32 against the railway track to achieve the effect of heat conduction. On the other hand, when the train passes by, the wind generated will blow the fan 43 to rotate. The rotation of the fan 43 will cause the energy storage assembly 5 to store energy. During the process of the energy storage assembly 5 releasing the stored energy, it will drive the water pumping assembly 6 to move and guide the water in the water storage tank 1 onto the heat dissipation element 2. The contact between the heat dissipation element 2 and the telescopic element 31 can thus dissipate heat and cool down the telescopic element 31, the heat conduction block 32, and the railway track. The present invention can reduce manual participation. The entire heat dissipation and cooling process utilizes the wind generated when the train passes by, which is clean energy, and solves the technical problems of large workload and poor cooling effect for cooling the railway track in summer.

[0025] It should be emphasized that the energy storage assembly 5 is for energy storage work. After the train passes by, the temperature of the railway track will rise. The present invention provides the energy storage assembly 5 to cope with the rise in the temperature of the railway track after the train passes by, and the energy storage assembly 5 can produce the effect of delayed watering.

[0026] It should be noted that the thermally expandable liquid can be a liquid with a high coefficient of thermal expansion such as mercury or kerosene, which can expand in summer. The distance between the heat conduction block 32 and the railway track can be set to the distance that can be reached after expansion. Preferably, the thermally expandable liquid is preferably kerosene.

[0027] It can be understood that the water storage tank 1 can be used to collect rainwater and pour water manually through the through holes 12 provided thereon. Preferably, the water storage tank 1 is arranged underground, and a pit can be dug on the ground to place the water storage tank 1.

[0028] In an embodiment of a heat dissipation device for a railway track, the first transmission module includes a first worm 41, a first worm wheel, and a transmission rod 42. Two fans 43 are fixedly connected to both ends of the first worm 41. The first worm 41 meshes with the first worm wheel. The transmission rod 42 is fixedly connected with the first worm wheel, and the end of the transmission rod 42 away from the first worm wheel is connected to the receiving part.

[0029] In this embodiment, by adopting the combination of a worm and a worm wheel, firstly, the direction of rotation can be changed, which is convenient for arranging the positions of the transmission component 4 and the energy storage component 5. Secondly, the worm and worm wheel have a certain self-locking property, which can avoid wasting energy due to reverse rotation, thereby improving the energy utilization rate.

[0030] In an embodiment of a heat dissipation device for a railway track, the transmission rod 42 is a worm, and the thread of the transmission rod 42 is provided at the end away from the first worm wheel. The energy storage component 5 includes a second worm wheel 51, a transmission shaft 52, a spring 53, and an output disc 54. The second worm wheel 51 is fixedly connected to the transmission shaft 52 and meshes with the transmission rod 42. The inner ring end of the spring 53 is fixedly connected to the transmission shaft 52, and the outer ring end is fixedly connected to the output disc 54. The output disc 54 is connected to the pumping component 6.

[0031] In this embodiment, it can be understood that the principle of the energy storage component 5 is the same as that inside a mechanical watch. By setting the transmission rod 42 as a worm and cooperating with the second worm wheel 51, it also has the effects of changing the rotation direction and self-locking, thereby enabling the spring 53 to store energy. Moreover, when the spring 53 releases energy, it will not drive the second worm wheel 51 to reverse due to the self-locking of the second worm wheel 51 and the transmission rod 42, but only drive the output disc 54 to rotate, improving the energy utilization rate.

[0032] In addition, it can be understood that the transmission rod 42 is the second worm.

[0033] It can be understood that the release of the energy stored in the spring 53 is continuous and can release energy continuously for a period of time. Preferably, structures such as a gearbox and a speed reducer 9 can be set to achieve the effect of intermediate connection with the pumping component 6. Specifically, taking the speed reducer 9 as an example, there are multiple groups of gears with a transmission ratio greater than one inside the speed reducer 9, and different transmission ratios can be set according to the actual situation to better drive the pumping component 6.

[0034] In one embodiment, the transmission rod 42 itself can form the transmission shaft 52, thus eliminating the second worm wheel 51 and the transmission shaft 52 and simplifying the structural composition.

[0035] In an embodiment of a heat dissipation device for a railway track, the heat dissipation element 2 is provided with a plurality of mesh holes 21 along the extending direction of the railway track.

[0036] In this embodiment, by providing the mesh holes 21 on the heat dissipation element 2, the heat dissipation element 2 can be better cooled by the wind.

[0037] In an embodiment of a heat dissipation device for a railway track, the water pumping assembly 6 includes a water pumping cylinder 61, a pressing pump, and a connecting pipe 63. The water pumping cylinder 61 communicates with the accommodating space. One end of the connecting pipe 63 communicates with the water pumping cylinder 61, and the other end is located above the heat dissipation element 2. The pressing pump is connected to the end of the water pumping cylinder 61 away from the water storage tank 1, and the pressing pump can be driven by the output disc 54 to reciprocate, so as to guide the water in the water storage tank 1 onto the heat dissipation element 2 through the water pumping cylinder 61 and the connecting pipe 63 in sequence.

[0038] In this embodiment, the power source 62 of the water pumping assembly 6 is a pressing pump. By reciprocally driving the pressing pump, the water in the water storage tank 1 is pumped above the heat dissipation element 2. At this time, the structure of the output disc 54 can be a structure form that can realize the reciprocating movement of the pressing pump. For example, the output disc 54 can be a cam structural member, and the rotation of the cam can make the pressing pump reciprocate in the vertical direction.

[0039] It should be emphasized that in this embodiment, the cam structure may not always be in contact with the pressing pump.

[0040] Combined with the previous embodiments, in a preferred embodiment, taking the extending direction of the railway track as the X direction as an example, the extending direction of the first worm 41 is the X direction, the extending direction of the transmission rod 42 is the Y direction perpendicular to the X direction, and the extending direction of the water pumping cylinder 61 is the vertical direction, that is, the Z direction.

[0041] In an embodiment of a heat dissipation device for a railway track, the water pumping element includes a water pumping cylinder 61, a screw conveyor, and a connecting pipe 63. The water pumping cylinder 61 communicates with the accommodating space. One end of the connecting pipe 63 communicates with the water pumping cylinder 61, and the other end is located above the heat dissipation element 2. The screw conveyor is received in the water pumping cylinder 61, and the end of the screw conveyor meshes with the output disc 54 and can be driven by the output disc 54 to rotate.

[0042] In this embodiment, the power source 62 of the water pumping assembly 6 is a screw conveyor. A screw conveyor is a structural member that can drive a liquid or a solid to be pushed along one direction when rotating. Since the water pumping cylinder 61 is vertically arranged in a different direction from the output disc 54, the two can be meshed through bevel gears to change the direction.

[0043] In an embodiment of a heat dissipation device for a railway track, the heat dissipation device further includes a sponge layer. The sponge layer is laid on the heat dissipation element 2 and is used to receive the water led out from the connecting pipe 63.

[0044] In this embodiment, by providing a sponge layer, water can be evenly distributed on the heat dissipation element 2.

[0045] In an embodiment of a heat dissipation device for a railway track, the heat dissipation device further includes a protective cover 7. The protective cover 7 covers the water storage tank 1 and forms a box structure with the water storage tank 1, having a ventilation hole that penetrates along the extending direction of the railway track. The heat dissipation element 2, the transmission assembly 4, the energy storage assembly 5, and the water pumping assembly 6 are housed in the ventilation hole.

[0046] In this embodiment, by providing the protective cover 7, it is possible to avoid being affected by sundries such as dust and gravel, and the formed ventilation hole can better guide the flow direction of the wind, enabling the fan 43 to rotate better.

[0047] In an embodiment of a heat dissipation device for a railway track, the heat dissipation device further includes two side plates 8. The two side plates 8 are detachably connected to the protective cover 7, and when the two side plates 8 are both connected to the protective cover 7, they can close the two orifices of the ventilation hole.

[0048] Combined with the previous embodiments, it should be noted that the telescopic element 31 can pass through the protective cover 7 to contact the heat dissipation element 2.

[0049] In this embodiment, by providing the two side plates 8, a sealed space can be formed in cooperation with the protective cover 7, so that when the device is not used in non-summer, it can be sealed to prevent the wind from entering the ventilation hole and causing the fan 43 to rotate.

[0050] Combined with the previous embodiments, it should be noted that the fixing method of the wheel and the rod can be realized in various forms, such as welding, key fitting, etc.

[0051] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as within the scope described in this specification.

[0052] The above embodiments only represent several implementation manners of the present invention. Their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of this invention patent shall be subject to the appended claims.
