[0025] See also Figure 1 , this embodiment provides a schematic diagram of a wind energy collector for high-speed rail transportation, such as Figure 1 As shown, the wind energy collector 100 for high-speed rail transit includes a support structure 110, a wind plate 120 and a generator 130. The support structure 110 is arranged on both sides of a track 140; the wind plate 120 is vertically fixed on the support structure 110, and the plane extension direction of the wind plate 120 is consistent with the direction of the track 140. The wind plate 120 is used to collect wind pressure when a vehicle 150 passes along the track; the generator 130 generates electricity based on the wind pressure.

[0026] In this embodiment, wind panels 120 are arranged on both sides of the track 140 to collect wind pressure or wind energy, and then the generator 130 is driven to generate electricity. This can not only reduce the harm caused by the outward spread of track noise to the surrounding environment, but also use the energy generated to provide uninterrupted power supply to communication, lighting, monitoring and other equipment arranged on both sides of the track, which not only saves power wiring but also realizes the secondary utilization of energy. Figure 6It is a schematic diagram of a simulation curve of gas pressure on the wind plate 120 on one side of the track 140 when the vehicle passes at different speeds in one embodiment of the present invention, that is, the faster the train speed, the more energy can be collected.

[0027] Figure 2 A schematic diagram of another high-speed rail transit wind energy collector 200 is provided for an embodiment of the present invention, such as Figure 2 As shown, the wind energy collector 200 for high-speed rail transit in this embodiment includes: a support structure 110, a wind plate 120 and a generator 130. The support structure 110 is arranged on both sides of the track; the wind plate 120 is vertically fixed on the support structure 110, and the plane extension direction of the wind plate 120 is consistent with the track direction. The wind plate 120 is used to collect wind pressure when the vehicle passes along the track; the generator 130 generates electricity based on the wind pressure.

[0028] In this embodiment, the wind energy collector 200 for high-speed rail transit further includes a spiral precession structure 150 connected to the wind plate 120, and the spiral precession structure 150 rotates according to the swing of the wind plate 120 to drive the generator 130 to generate electricity. Specifically, the spiral precession structure 150 includes a screw 151 and a screw sleeve 152, and the screw sleeve 152 is fixed to the wind plate 120, and is used to generate linear motion according to the swing of the wind plate 120 perpendicular to the track direction. One end of the screw 151 is coupled with the rotating shaft of the generator 130, and the other end of the screw 151 is rotatably connected with the screw sleeve 152. When the wind plate 120 swings outward due to the wind pressure generated by the vehicle passing along the track, the screw sleeve 152 swings together with the wind plate 120 to generate linear motion, and the screw 151 generates rotational motion under the push of the screw sleeve 152, thereby driving the rotating shaft of the generator 130 to rotate to achieve power generation.

[0029] In one embodiment, the generator 130 is fixed to the support structure 110 and raised to a preset height. Figure 2 As shown, the spiral precession structure 150 extends in the horizontal direction and is arranged between the generator 130 and the wind plate 120. In an alternative embodiment, the generator 130 is fixed to the support structure 110 and arranged near the ground. Figure 3 As shown, there is a preset inclination in the horizontal direction, for example, 30-60 degrees, and it is arranged and connected between the generator 130 and the wind plate 120. Preferably, one end of the spiral precession structure 150 is against the height of 1 / 3-1 / 2 of the wind plate 120. In this way, the generator 130 is placed more stably, and the wind plate 120 exerts a greater force on the spiral precession structure 150 when it swings and tilts, so that power generation can be achieved even if the wind force is small, and the power generation efficiency is higher.

[0030] In one embodiment, the cross-section of the wind plate 120 perpendicular to the track direction includes at least one arc line facing the track. Such a structure can increase the force of wind pressure.

[0031] In one embodiment, the support structure 110 is connected to the root of the wind plate 120 through an elastic member 170, and the elastic member 170 is used to maintain the vertical state of the wind plate 120 after the vehicle drives away. In one embodiment, the elastic member 170 can be one or more springs or elastic sheets.

[0032] In one embodiment, each wind plate 120 is provided with at least two spiral precession structures (not shown), and the two spiral precession structures are arranged at intervals in front and behind the wind plate along the track direction to balance the force on the wind plate and prevent the wind plate from tipping over under wind pressure.

[0033] In one embodiment, the wind energy collector of any of the above-mentioned high-speed rail transit may further include a solar panel 180, which is fixedly arranged in an arc position on the top of the wind plate 120, for converting solar energy into electrical energy. In one embodiment, the energy collector of the high-speed rail transit may further include an energy storage module (not shown) for storing electrical energy generated by a generator and / or a solar panel. In one embodiment, in order to ensure the efficiency of energy collection, the size of the wind plate 120 may be greater than a preset threshold, for example, at least 2 meters high and 10 meters wide. Preferably, the edge of the wind plate 120 further includes a blocking structure or a reinforcing structure facing the track to enhance the convergence effect of the airflow while reducing the deformation of the wind plate 120.

[0034] In one embodiment, the energy collector of the above-mentioned high-speed rail transit may further include a lighting module (not shown), a communication module (not shown) and / or a monitoring module (not shown) connected to the energy storage module, and the lighting module, communication module or monitoring module is powered by the energy storage module. The communication module is used to receive lighting instructions and / or monitoring instructions sent by the user through a mobile terminal, and the lighting instructions are used to turn on or off the lighting module, and the monitoring instructions are used to turn on or off the monitoring module. The lighting module, communication module or monitoring module in this embodiment can be self-powered by collecting wind energy, without the need for separate wiring to draw electricity, which is convenient for track maintenance personnel to control lighting and achieve safety monitoring during maintenance along the way.

[0035] Figure 4 A schematic diagram of another wind energy collector 400 for high-speed rail transit is provided for an embodiment of the present invention. The wind energy collector 400 for high-speed rail transit of this embodiment includes: a support structure 110, a wind plate 120 and a generator 130. The support structure 110 is arranged on both sides of the track; the wind plate 120 is vertically fixed on the support structure 110, and the plane extension direction of the wind plate 120 is consistent with the track direction. The wind plate 120 is used to collect wind pressure when the vehicle passes along the track; the generator 130 generates electricity based on the wind pressure.

[0036] In this embodiment, the wind plate 120 includes a plurality of converging guide structures 121 arranged in a matrix. The converging guide structures 121 generate a plurality of high-pressure airflows according to the wind pressure received by the wind plate 120. The high-pressure airflows are used to drive the fans 132 of a plurality of micro-generators 131 to rotate to generate electricity.

[0037] Further, see also Figure 5 The converging and guiding structure 121 includes a trumpet-shaped airflow converging structure 1211 with an opening toward the track and a guiding pipe 1212 connected to the tail of the airflow converging structure 1211, and the air outlet of the guiding pipe 1212 is arranged toward the fan 132 of the micro-generator 131. In this embodiment, the fan 132 of the micro-generator 131 can be integrated into the tail of the guiding pipe 1212 to improve the efficiency of rotation. The micro-generator 131 can be fixed to the outside of the guiding pipe 1212 or fixed to the frame 112.

[0038] Furthermore, the wind plate 120 may also include a plurality of sub-air pressure collection panels 122 that can be spliced ​​with each other, each converging guide structure 121 is fixedly arranged on the sub-air pressure collection panel 122, and the sub-air pressure collection panels 122 are spliced ​​with each other through a first interdigitated structure 122A arranged at the edge. In this embodiment, the interdigitated structure between the array-spliced ​​sub-air pressure collection panels 122 not only plays a role of flexible splicing, but also can slow down the airflow passing between the sub-air pressure collection panels 122, so that most of the airflow generated by the wind pressure is introduced from the trumpet-shaped airflow converging structure 1211 into the guide pipe 1212 to achieve efficient power generation.

[0039] Further, the support structure 110 includes a base 111 and a frame 112 vertically fixed to the base 111, and a row of sub-air pressure collection panels 122 at the bottom of the wind plate 120 are fixed to the second interdigitated structure 113B of the base 111 through a first interdigitated structure 122A. In this embodiment, each sub-air pressure collection panel 122 is fixed to the frame 112 through a plurality of elastic beams 140. In one embodiment, each sub-air pressure collection panel 122 is fixed to the frame 112 through four elastic beams 140, that is, each corner of the sub-air pressure collection panel 122 is fixed to the frame 112 through an elastic beam 140. In one embodiment, the elastic beam 140 may be a spring. In this embodiment, these elastic beams 140 can not only reduce the impact of the wind plate 120 on the frame 112 when the wind pressure is too high, but also adjust the direction of the horn inlet. Specifically, since the four corners of the sub-air pressure collection panel 122 that fixes the horn-shaped airflow convergence structure 1211 are elastically fixed, the sub-air pressure collection panel 122 corresponding to each guide opening of the horn-shaped airflow convergence structure 1211 can rotate with the air pressure direction, so that under the action of air pressure, the sub-air pressure collection panel 122 is always facing (perpendicular to) the airflow direction, which can not only more efficiently collect the wind pressure generated by the passing train, but also better collect the ambient air flow to generate wind energy.

[0040] The above specific implementations do not constitute a limitation on the protection scope of the present invention. It should be understood by those skilled in the art that various modifications, combinations, sub-combinations and substitutions can be made according to design requirements and other factors. Any modification, equivalent substitution and improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
