Description

Technical Field

[0001] The utility model relates to a high-speed train bidirectional windage braking device capable of recovering kinetic energy, and relates to the technical field of railway vehicle auxiliary braking, in particular to a high-speed train bidirectional windage braking device capable of recovering kinetic energy. Background Art

[0002] my country's high-speed trains generally use compound braking, that is, multiple braking methods are used at the same time, and the braking force comes from air braking, electric braking and non-adhesion braking. The air braking method mainly uses wheel disc braking and axle disc braking. The electric braking method mainly uses resistance braking and regenerative braking. The non-adhesion braking method currently mainly uses disc eddy current braking, magnetic rail braking and track eddy current braking. The basic idea of ​​this braking method is to convert the kinetic energy of the train into electrical energy or thermal energy, and then absorb or release it. When emergency braking is required, the train should make full use of the regenerative braking force, and the rest should be supplemented by air braking. When the train is running on a railway section without electricity or the electric brake fails, air braking is used as the last safety measure.

[0003] Wind resistance braking is to increase air resistance by installing a brake wind resistance plate on the surface of the train body to achieve a braking effect. Compared with the traditional adhesion braking method, the braking force generated by wind resistance braking comes from the air resistance caused by the deployment of the wind resistance brake plate. This resistance is proportional to the square of the speed, and as the train speed increases, the braking effect it produces becomes more significant. When the train runs at a speed level above 300km / h, the air resistance the train is subject to accounts for more than 80% of the total resistance. At the same time, the braking kinetic energy of the train is proportional to the square of the speed, and as the speed of the train continues to increase, the adhesion braking force will also decrease significantly, which cannot meet the braking requirements of high-speed trains. It can be seen that in the speed-up stage of high-speed trains, wind resistance braking can make up for the current situation of insufficient adhesion braking capacity of trains, especially when the train needs emergency braking, the effect of wind resistance braking is particularly obvious. At the same time, this braking method uses air resistance as braking force and does not require additional energy consumption.

[0004] The existing high-speed train windage braking device has the following main problems:

[0005] (1) The current train wind resistance braking devices are still in the conceptual stage, with few practical cases. The designed installation position is basically fixed on the top of the train. Although some patents claim that bidirectional braking can be achieved, a set of devices is required for each direction, which takes up a lot of space and has a large weight.

[0006] (2) The existing wind resistance braking device of high-speed trains has a single function and can only provide braking force, but cannot effectively utilize the wind energy during braking.

[0007] In view of the problems existing in the above-mentioned prior art, it is very necessary to study and design a new type of high-speed train bidirectional windage braking device for recovering kinetic energy, so as to overcome the problems existing in the prior art. Summary of the invention

[0008] According to the technical problems raised by the above-mentioned prior art, a high-speed train bidirectional windage brake device for recovering kinetic energy is provided. The utility model mainly realizes the deployment and closure of the windage brake plate and the working direction of the windage device through an electric-driven sliding support structure. The windage plate device proposed by the utility model has a simple structure, a light weight, and is easy to install and operate.

[0009] The technical means adopted by the utility model are as follows:

[0010] A high-speed train bidirectional windage brake device for recovering kinetic energy is installed on the top of the carriage. The whole windage plate device can be modularized and attached to the roof during normal operation of the train, keeping consistent with the overall appearance of the train. It includes: a windage plate structure, a rotating structure, a fan blade structure, and a sliding support structure.

[0011] Furthermore, the wind resistance plate structure is installed on the top of the carriage through a rotating structure, so that the high-speed train bidirectional wind resistance brake device for recovering kinetic energy can rotate in the horizontal plane, ensuring that the working direction is consistent with the running direction of the train;

[0012] Furthermore, the fan blade structure is mounted on the wind resistance plate structure to recover wind energy during braking and transfer it to the energy storage device;

[0014] Furthermore, the rotating structure, the fan blade structure and the sliding support structure are connected to an external central control system.

[0015] Further, the wind resistance plate structure includes: a wind resistance brake plate and a base;

[0016] Furthermore, the wind resistance brake plate is a rectangular plate structure, on which a plurality of circular grooves for mounting the fan blade structure are evenly distributed;

[0017] Furthermore, the main body of the base is a thin plate-shaped structure made of aluminum alloy, and the inner sides of the two side walls thereof are provided with sliding grooves for assembling the sliding support structure;

[0018] Furthermore, the base is mounted on the top of the carriage through a rotating structure;

[0019] Furthermore, the two ends of the wind resistance brake plate are hinged to the two side walls of the base to achieve the opening and closing of the wind resistance brake plate.

[0020] Furthermore, a number of through holes for wind to pass through are evenly distributed at the bottom of the circular groove; the circular groove is numerically analyzed and optimized using the CFD method to ensure that when the wind resistance brake device of the train is activated, the wind can pass through the circular groove and the through holes to drive the fan to rotate, and the influence of the through holes on the resistance provided by the wind resistance brake plate is minimized.

[0021] Furthermore, the fan blade structure includes: a fan blade and a fan blade base;

[0022] Furthermore, the fan blades are made of carbon fiber material and are mounted on the motor shaft of the fan blade base;

[0023] Furthermore, the fan blade base is made of aluminum alloy, an energy conversion device is installed inside it, and the fan blade base is fixed in the circular groove;

[0024] Furthermore, the fan blades rotate under the action of wind resistance, thereby driving the rotating shaft on the fan blade base to recover energy, driving the energy conversion device inside the fan blade base to work to realize wind energy generation and storage.

[0025] Furthermore, the sliding support structure includes: a connecting rod mechanism, a linear slide block, a cylinder drive device and a solenoid valve;

[0026] Furthermore, the linear guide slider is installed in a slide groove on the side wall of the base and is axially connected to one end of the connecting rod mechanism;

[0027] Furthermore, the other end of the connecting rod mechanism is hinged to the upper end of the side of the linear slide block;

[0028] Further, the cylinder drive device is connected to the solenoid valve and installed inside the side wall of the base;

[0029] Furthermore, the front end of the cylinder rod of the cylinder driving device is connected to the linear slide block; the power system controls the cylinder driving device through the solenoid valve to drive the linear slide block to slide in the slide groove, thereby controlling the opening and closing of the windage brake plate through the connecting rod mechanism.

[0030] Furthermore, the connecting rod mechanism is a straight rod type non-powered device made of stainless steel, which can provide sufficient strength to support the wind resistance brake plate while also reducing the weight of the device and external corrosion;

[0031] Furthermore, the connecting rod mechanism is located in the gap between the wind resistance brake plate and the base when in the closed state, and has no additional protruding parts, so as not to affect the air resistance of the entire device when it is closed; the connecting rod mechanism is perpendicular to the base when the wind resistance brake plate is fully opened, and is parallel to the base when the wind resistance brake plate is fully closed.

[0032] Further, the rotating structure includes: a mounting seat and an electric rotating mechanism;

[0033] Furthermore, the mounting base is made of aluminum alloy and is fixed to the top of the carriage by bolts;

[0034] Furthermore, the electric rotating mechanism is installed between the base and the mounting seat to realize the horizontal rotation of the bidirectional windage braking device of the high-speed train for recovering kinetic energy.

[0035] Furthermore, the working process of the high-speed train bidirectional windage braking device for recovering kinetic energy includes the following steps:

[0036] 81. Normal running state of high-speed train: the bidirectional windage brake device of the high-speed train for recovering kinetic energy is in a non-operating state, and the windage brake plate is retracted into the base;

[0037] 82. Braking or emergency braking state: the power system controlled by the central system starts to work, the power system controls the cylinder drive device through the solenoid valve, the cylinder drive device controls the linear slide block to run on the track through the extension and contraction of the cylinder rod, the linear slide block is connected to one end of the connecting rod mechanism through a rotating shaft, and the linear slide block drives the connecting rod mechanism to move when sliding in the slide groove; driven by the connecting rod mechanism, the wind resistance brake plate connected to the other end of the connecting rod mechanism through the rotating shaft opens; when the wind resistance brake plate is fully opened, the cylinder drive device controls the linear slide block to stop sliding; during the braking process, the wind drives the fan blades in the countersunk hole to rotate, and the rotation of the fan blades then drives the rotating shaft of the fan blade base to rotate, so that the generator generates electricity;

[0038] 83. Braking end recovery state: The power system starts the cylinder drive device through the solenoid valve to control the linear slide block to slide to the other end of the track, which drives the connecting rod mechanism to move through the rotating shaft. Under the movement of the connecting rod mechanism, the wind resistance brake plate closes the wind resistance brake plate through the rotating shaft; when the wind resistance brake plate is completely closed, the cylinder drive device controls the linear slide block to stop running;

[0039] 84. Reversing braking state: When the train is to run in the opposite direction, the electric rotating mechanism is activated to rotate the base in the horizontal plane so that its working direction is consistent with the direction of train travel.

[0040] When the train speed reaches 300km / h or above and braking or emergency braking is required, the wind resistance brake plate is used for braking. The cylinder drive device will immediately push the linear slide block from one end of the track to the other end of the track under the control of the solenoid valve, so that the wind resistance brake plate changes from a closed state to a fully open state, so that the wind resistance brake plate provides the maximum wind resistance braking force for the train, thereby achieving the braking force required for emergency braking or high-speed braking of the train; when the train uses the wind resistance brake plate for braking at low speed, the cylinder drive device will move the linear slide block to the center of the track under the control of the solenoid valve, so that the wind resistance brake plate is in a semi-expanded state, which can meet the braking force required for low-speed braking and reduce unnecessary energy waste.

[0041] Compared with the prior art, the utility model has the following advantages:

[0042] 1. The high-speed train bidirectional windage brake device for recovering kinetic energy provided by the utility model optimizes the existing windage brake device through CFD numerical simulation. The optimized values ​​are shown in Table 1. The resistance data is the resistance data of the corresponding model obtained by the fluid calculation software Ansys-Fluent through simulation calculation. While retaining the braking performance of the windage brake plate, an additional wind energy recovery structure is added. This allows the high-speed train to generate wind power during the braking process without consuming additional energy, and is easy to install and maintain, solving the shortcomings of the existing high-speed train windage plate device;

[0044]

[0045] 2. The high-speed train bidirectional windage brake device for recovering kinetic energy provided by the utility model ensures the reliability of operation, adopts a simple slider connecting rod mechanism to drive the opening and closing of the windage brake plate, has a simple structure and is easy to operate;

[0046] 3. The high-speed train bidirectional windage braking device for recovering kinetic energy provided by the utility model can adjust the working direction according to the running direction of the train, so it does not include components with different working directions, which greatly reduces the weight of the device itself;

[0047] 4. The high-speed train bidirectional windage braking device for recovering kinetic energy provided by the utility model simplifies the structural design and personnel operation, has a simple device structure, and is easy to install and maintain.

[0048] In summary, the technical solution of the utility model solves the problems that the windage brake devices in the prior art are mostly symmetrical in structure, complex in structure, heavy in weight, complicated in installation and operation, and occupy a large space.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use.

[0066] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the utility model. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0067] Unless otherwise specifically stated, the relative arrangement of the parts and steps described in these embodiments, numerical expressions and numerical values ​​do not limit the scope of the utility model. At the same time, it should be clear that, for ease of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship. The technology, method and equipment known to ordinary technicians in the relevant field may not be discussed in detail, but in appropriate cases, the technology, method and equipment should be regarded as a part of the authorization specification. In all examples shown and discussed here, any specific value should be interpreted as merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following drawings, so once a certain item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0068] In the description of the present utility model, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present utility model and simplifying the description. Unless otherwise stated, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present utility model: the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0069] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure.

For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below their position devices or structures". Thus, the exemplary term "above" may include both "above" and "below". The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0070] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components.
