[0002] With the rapid development of high-speed railways, in order to allow everyone to enjoy the convenience brought by high-speed railways, high-speed railways have gradually spread to various places across the country, including some places with harsh environments, such as more and more tunnel-bridge transition sections. Under strong crosswind conditions, when a high-speed train passes through a tunnel-bridge transition section, its aerodynamic performance will change significantly, and the stability of operation will be significantly challenged, which may even endanger the safe operation of the train and cause serious accidents such as derailment and overturning. Therefore, setting up a windbreak wall in the tunnel-bridge transition section has become an important safety protection measure. However, the ordinary windbreak wall structure has limited blocking effect on crosswinds. In extreme weather and poor geographical environments, ordinary windbreak walls cannot guarantee the stable operation of trains.

[0003] Therefore, there is an urgent need for an energy-saving windbreak wall structure that can be applied to various wind speed environments and even extreme weather conditions to ensure the driving safety of trains in various weather and environments. Utility Model Content

[0025] The embodiments of the present invention are described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered by the claims.

[0026] Example:

[0027] A wind power generation windbreak wall structure, reference Figure 1 and Figure 2 , including a windshield body, a speed measuring component and a wind power generation component; the windshield body includes a windshield single piece 3 located on both sides of the road; the speed measuring component includes an anemometer 6 and a receiver connected to the anemometer signal; the anemometer 6 is arranged corresponding to the windshield single piece 3, and the receiver is arranged on the train traveling on the road; the wind power generation component is connected to the anemometer. The receiver is connected to the control system on the train. Through the above arrangement, the wind speed measured by the anemometer in real time is sent to the train end through the receiver, so that the control system of the train judges whether the windshield structure can ensure sufficient windshield effect when passing through the bridge-tunnel connection section with complex and changeable wind fields ahead according to the wind speed and the speed of the train, so as to judge whether the train needs to slow down or stop, thereby effectively ensuring the driving safety of the train in various wind speed environments, especially in extremely windy weather, it can also ensure safety by stopping, and resume high-speed driving after stabilization, which also effectively ensures the resumption efficiency of trains in extreme weather. In addition, the windbreak wall structure of the utility model has its own wind power generation component, which uses wind power to generate electricity while blocking the wind, thereby powering the speed measuring component through itself, saving energy, and not requiring connection to an external power supply, which is convenient to use and construct.

[0028] The speed measuring assembly further includes a distance detection device for detecting the distance between the train and the anemometer 6, and the distance detection device is connected to the anemometer 6. Through the distance detection device, a detection mechanism is preferably set at 10 km from the anemometer to detect the distance between the train and the windshield structure, so as to ensure that the wind speed signal can be sent before the train travels within 10 km of the windshield structure, so as to perform deceleration and other operations in advance to ensure the safety of the train and the stability of driving.

[0029] The anemometer 6 is a three-way anemometer.

[0030] like Figure 1 and Figure 3 The windshield wall unit 3 is provided with a plurality of ventilation holes along the length direction of the road, and the wind power generation assembly includes a plurality of wind turbines 4 correspondingly arranged in the ventilation holes, and the plurality of wind turbines 4 are connected to the anemometer 6.

[0031] The device further comprises a storage battery 5 , to which the wind turbine 4 and the anemometer 6 are both connected.

[0032] The radius of the wind turbine 4 is 1m, and the length of its blade is 0.76m. The length of the windshield wall single piece 3 is 200m, the width is 0.2m, and the height is 4m. The anemometer 6 and the windshield wall single piece 3 are arranged in sequence along the length direction of the road, and are at least 2m apart. The anemometer 6 is located 2m outside the windshield wall single piece 3. The material of the windshield wall structure is structural steel plate. Concrete is poured at the bottom of the windshield wall single piece to ensure the durability of the windshield wall single piece under strong crosswinds. The wind turbine is welded to the windshield wall single piece through a fixed support.

[0033] The train speed safety limit and crosswind speed results must meet the following requirements:

[0034] The crosswind speed and vehicle speed limit can refer to the characteristic wind curve: Vt = -7Vw + 325;

[0035] Where Vw represents the crosswind speed (m / s), and Vt is the corresponding vehicle speed safety limit (km / h).

[0036] The crosswind speed monitored by the anemometer is processed through the signal transmission system, and the processed signal is then transmitted to the train control system to determine whether the train needs to slow down.

[0037] When the crosswind speed monitored by the anemometer 6 is a certain value, the wind speed signal is transmitted to the train to determine whether the train speed has reached the limit value and whether it needs to slow down when passing through the tunnel-bridge transition section. For example: when the crosswind speed monitored by the anemometer 6 is 25m / s, the speed safety limit at this time is 150km / h. When the train speed is higher than 150km / h, the train begins to slowly slow down until the speed drops below the safety limit; when the train speed is lower than 150km / h, the train can safely pass through the tunnel-bridge transition section.

[0038] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
