Description

TECHNICAL FIELD

[0002] Rail tracks are classified into ballast tracks and non-ballast tracks according to track structures. The ballast track is composed of rails, sleepers and ballast, and the track is surrounded by gravel, which is also commonly referred to as a gravel bed track. The non-ballast track uses a concrete or asphalt mixture to replace the granular gravel bed. Due to the good integrity, track stability and small maintenance workload of the non-ballast track, high-speed trains mostly use non-ballast tracks. However, the overall track bed structure is relatively dense, and the main heat dissipation path is through the surface of the concrete or asphalt layer to the air, and the heat dissipation area is relatively small, and the heat dissipation speed is slow. Moreover, the specific heat capacity of concrete and asphalt is large, and the temperature rises slowly after absorbing heat, but the heat is also released relatively slowly during heat dissipation, which is not conducive to rapid heat dissipation.

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. The telescopic element 31 contains a thermally expanding liquid, enabling it to drive the telescopic section to bring the heat conduction block 32 against the lower part of the railway track during summer. The end of the telescopic element 31 away 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 located at opposite ends of the first transmission module. The fans 43 rotate to receive airflow from passing trains and drive the first transmission module.

The water pumping component 6 is driven to the output section and is used to guide water in the containing space onto the heat dissipation element 2 when the energy storage mechanism releases stored energy.

[0040] In the embodiment, when the temperature is relatively high in summer, on one hand, the liquid inside the telescopic element 31 expands under the heat, pushes the heat-conducting block 32 to abut against the rail, and plays a heat-conducting effect, on the other hand, when the train passes, the wind brought by the train blows the fan 43 to rotate, the rotation of the fan 43 drives the energy storage assembly 5 to store energy, and the energy storage assembly 5 releases the stored energy to drive the water pumping assembly 6 to move and guide the water in the water storage tank 1 to the heat-dissipating element 2, the heat-dissipating element 2 is in contact with the telescopic element 31, so that the telescopic element 31, the heat-conducting block 32 and the rail can be cooled, the present application can reduce the manual participation, the whole cooling process utilizes the wind generated when the train passes, clean energy, and solves the technical problems of large work load and poor cooling effect of the rail in summer.

[0041] It should be emphasized that the energy storage assembly 5 is used for energy storage, and the temperature of the rail rises after the train passes, the present application sets the energy storage assembly 5 to cope with the rise of the temperature of the rail after the train passes, and the energy storage assembly 5 can generate a delayed watering effect.

[0042] It should be noted that the thermal expansion liquid can be mercury, kerosene or other liquid with high thermal expansion coefficient, which can expand in summer, and the distance between the heat-conducting block 32 and the rail can be set to the distance that can be reached after expansion, preferably, the thermal expansion liquid is kerosene.

[0043] It can be understood that the water storage tank 1 can be used to collect rainwater and manually pour water through the through hole 12 arranged thereon, preferably, the water storage tank 1 is arranged below the ground, and a pit can be opened on the ground to place the water storage tank 1.

[0044] In an embodiment of the heat dissipation device for the rail, the first transmission module comprises a first worm 41, a first worm wheel and a transmission rod 42, two fans 43 are fixedly connected to two ends of the first worm 41, the first worm 41 is engaged with the first worm wheel, the first worm wheel is fixedly connected to the transmission rod 42, and the end of the transmission rod 42 away from the first worm wheel is connected with the receiving part.

[0045] In the embodiment, the combination of the worm wheel and the worm is adopted, which can change the direction of rotation, so as to facilitate the arrangement of the positions of the transmission assembly 4 and the energy storage assembly 5, and the worm wheel and the worm have a certain self-locking property, which can avoid wasting the stored energy due to reverse rotation, so as to improve the energy utilization rate.

[0046] In an embodiment of the heat dissipation device for the rail, the transmission rod 42 is a worm, and the transmission rod 42 is provided with a thread at an end thereof away from the first worm wheel.

The output disc 54 is connected to the water pumping assembly 6.

[0047] In the embodiment, it can be understood that the principle of the energy storage assembly 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, the same effect of changing the rotation direction and self-locking is achieved, so that the clockwork spring 53 stores energy, and the release of the energy storage of the clockwork spring 53 will not drive the second worm wheel 51 to reverse, but only drive the output disc 54 to rotate, thereby improving the energy utilization rate.

[0048] In addition, it can be understood that the transmission rod 42 is a second worm.

[0049] It can be understood that the release of the energy storage of the clockwork spring 53 is continuous, and the energy can be continuously released for a period of time.

The auger is accommodated in the water pumping cylinder 61, the end of the auger is engaged with the output disc 54, and the auger can rotate under the driving of the output disc 54.

[0058] In the embodiment, the power source 62 of the water pumping assembly 6 is an auger, which is a structure capable of driving liquid or solid in one direction when rotating. Since the water pumping cylinder 61 is vertically arranged and the direction of the output disc 54 is different, the two can be engaged through bevel gears to change the direction.
