Description

Technical Field

[0001] The utility model relates to the field of aerodynamics of railway vehicles, and in particular to a high-speed train windage braking device with an energy recovery function. Background Art

[0002] As high-speed railways continue to speed up, the requirements for the braking performance of high-speed trains are also increasing. Traditional braking devices are difficult to adapt to the braking needs of higher-speed trains, especially when the train is in emergency braking. At present, the braking system of high-speed trains uses traction motors that mainly use regenerative braking and disc brakes that use friction. 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] Compared with the traditional adhesion braking method, the braking force generated by wind resistance braking comes from the air resistance brought 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. Therefore, the wind resistance braking method has obvious advantages during high-speed braking. At the same time, this braking method uses air resistance as braking force, does not require additional energy consumption, and also plays a role in energy saving, which can be used as a supplement to the adhesion braking of high-speed trains.

[0004] The existing conceptual train windage brake device 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 in each direction, which takes up a lot of space and is heavy. In addition, the windage brake plate device has a single function and only has a certain braking function, and does not recover high-quality kinetic energy. Summary of the invention

[0005] According to the technical problems raised above, a high-speed train wind resistance brake device with energy recovery function is provided. The utility model mainly realizes the raising and lowering of the brake plate and the adjustment of the braking working direction through an electric drive device, provides braking force for the high-speed train, and recovers wind energy and generates electricity while braking. The brake plate device proposed by the utility model has a compact structure, small footprint, light weight, and is easy to install and operate.

[0006] The technical means adopted by the utility model are as follows:

[0007] A high-speed train windage braking device with energy recovery function, comprising:

[0008] A brake plate, a connecting rod mechanism, a first drive device slider, a base, a baffle, a mounting seat and a second drive mechanical locking device, a third drive device connecting the baffle and the base, a fourth drive device connecting the base and the mounting seat, and a power generation device located on both sides of the brake plate;

[0009] The first driving device slider is connected to the connecting rod mechanism and is installed on the groove slide rail of the base. The movement of the connecting rod mechanism is controlled by sliding in the slide rail to control the brake plate unit to open and close.

[0010] The second driving mechanical lock device is installed inside the base slide rail, and performs mechanical locking when the brake plate is opened and closed, so that the device remains stable during the operation of the train;

[0011] The third driving device is installed at the connection between the baffle and the base, and is located on the bearing of the base for driving the baffle to rotate around the axis, so that the baffle is closed when the brake plate is working, and blocks the brake plate when the brake plate is not working;

[0012] The fourth driving device is installed at the connection part between the base and the mounting seat, and the rotating shaft located on the mounting seat enables the base to rotate in the horizontal plane, so that the working direction of the braking device is consistent with the travel direction of the train;

[0013] The power generation device is located on both sides of the brake plate cavity. When the brake plate is working, the fan blades installed on the device are rotated to drive the power generation device to generate energy.

[0014] Furthermore, the first drive device slider is an electric drive device, which is connected to the connecting rod mechanism through a rotating shaft and is installed on the groove slide rail of the base. The sliding of the first drive device slider along the groove slide rail on the base is achieved by an electric system. When the first drive device slider slides along the groove slide rail on the base, the connecting rod mechanism connected to it through the rotating shaft moves simultaneously with the first drive device slider to achieve the opening and closing of the connecting rod mechanism.

[0015] Furthermore, the connecting rod mechanism adopts an H-shaped connecting rod, which is a non-powered device, connected to the slider of the first driving device through a rotating shaft, and moves following the sliding of the slider of the first driving device; the connecting rod mechanism is connected to the brake plate structure through a rotating shaft, and the brake plate structure follows the opening and closing of the connecting rod mechanism to realize the opening and closing of the brake plate structure;

[0016] The connecting rod mechanism is made of stainless steel to obtain sufficient strength to support the brake plate;

[0017] The connecting rod mechanism is parallel to the upper plane of the base in the closed state.

[0018] Furthermore, the baffle is made of aluminum alloy, and is connected to the base through a third driving device on the base. The third driving device is an electric driving device, which can control the opening and closing of the baffle, closing the baffle when the brake plate is working, and opening the baffle when the brake plate is not working.

[0019] Furthermore, the base and the mounting seat are connected via a fourth driving device on the mounting seat, and the fourth driving device is an electric driving device, which can control the base to rotate horizontally relative to the mounting seat, thereby achieving consistency between the working direction of the braking device and the travel direction of the train.

[0020] Furthermore, the second drive mechanical lock device is installed in the groove of the base and is an electric drive device. When the brake plate is in the open or closed state, the second drive mechanical lock device is opened to mechanically lock the slider of the first drive device to ensure the stability of the device structure when the brake plate is in the open or closed state; the second drive mechanical lock device remains unlocked when the brake plate is switched between the closed and open states, and will not affect the sliding of the slider of the first drive device in the slide rail.

[0021] Furthermore, the base is made of aluminum alloy and has grooved slide rails for the first drive device slider and the second drive mechanical lock device to slide.

[0022] Furthermore, the power generation device is located on both sides of the inner cavity of the brake plate, with three groups on each side, respectively fixing the two ends of the corresponding fan blades. When the wind drives the fan blades to rotate, the device can convert kinetic energy into electrical energy; the fan blades are made of carbon fiber material and are connected to the brake plate through the rotating power generation devices on both sides of the brake plate; the fan blades are driven to rotate by the wind passing through the inside of the brake plate, thereby driving the rotating power generation devices on both sides of the brake plate to recover wind energy and generate energy.

[0023] Furthermore, the brake plate device is connected to the base through a rotating shaft, connected to the connecting rod mechanism through a rotating shaft, and connected to the fan blades through the power generation devices on both sides thereof; when the brake plate is in a working state, the second drive mechanical lock device is in a locked state, and the baffle is in a closed state. During braking, wind flows through the inside of the brake plate, driving the fan blades to rotate, and then driving the rotating power generation device to recover energy; when the brake plate is released from the working state, the baffle is first slowly opened from the closed state, the second drive mechanical lock device is released from the locked state, and the slider of the first drive device moves in the other direction to drive the brake plate device to slowly close, and finally the brake plate device is made parallel to the plane on the base, so that the second drive mechanical lock device returns to the locked state again, so that the baffle contacts and blocks the brake plate.

[0024] Furthermore, the baffle is made of aluminum alloy and is connected to the base via a third driving device.

[0025] Due to the adoption of the above technical solution, compared with the prior art, the utility model has the following advantages:

[0026] 1. The train windage braking device with energy recovery and steering functions provided by the utility model can recover the kinetic energy of the train during operation and convert it into electrical energy, which is fed back to the power supply equipment in the vehicle for electricity consumption, thereby reducing the train's dependence on external energy, reducing energy consumption and carbon emissions, and helping to achieve sustainable development and environmental protection goals.

[0027] 2. The utility model has an automatic steering function and only needs to install one set of equipment. The electric rotating mechanism between the mounting seat and the base can automatically adjust the working direction according to the direction of the train to achieve two-way braking, thereby significantly reducing the size of the wind resistance braking equipment, with a compact structure and a small footprint. This helps to improve the braking effect and handling performance of the train, reduce the braking distance and accident risks, and improve the operation safety of the train.

[0028] 3. The utility model can realize the opening and closing of the brake plate by sliding the slider, thereby driving the connecting rod mechanism to open and close. It has a simple structure and is easy to operate, and can provide braking resistance for high-speed trains more flexibly.

[0029] 4. In both the working state and the closed state of the brake plate, the mechanical lock device is in a locked state, which ensures the stability of the device during the operation of the train. When the train changes its direction of travel, the fourth electric drive device is activated to rotate the base 180° in the horizontal plane so that its working direction is consistent with the direction of travel of the train, providing braking resistance when braking is required. Because of the existence of the electric rotating mechanism, the working direction of the wind resistance brake plate can be changed according to the different travel directions of the train, so that only one set of wind resistance brake device is needed to provide braking resistance in the corresponding direction for the bidirectional train when braking, that is, it can provide braking resistance when running in the forward direction, and it can also provide braking resistance when running in the reverse direction.

[0030] 5. The device can provide non-adhesion braking force, reducing the dependence on the traditional adhesion braking system, reducing wheel-rail wear and maintenance costs, and also improving the operating efficiency of the train.

[0031] 6. The device has a compact structure, small footprint, light weight, and easy installation, and can be applied to various types of trains, including high-speed trains, intercity trains, etc. This flexibility and versatility make it potential for application in different railway systems and environments.

[0032] To sum up, the application of the technical solution of the utility model can solve many problems existing in the current wind resistance brake plate device, has important application prospects, can bring energy saving, cost reduction and safety improvement to the train industry, and is expected to be widely used and promoted in the future.

[0033] Based on the above reasons, the utility model can be widely promoted in the field of aerodynamics of railway vehicles. BRIEF DESCRIPTION OF THE DRAWINGS

[0056] Example 1

[0057] like Figure 1-13As shown, a high-speed train windage brake device with energy recovery function includes: a fan blade 1, a brake plate 2, a connecting rod mechanism 3 (connecting the brake plate and a driving device slider), a driving device slider 4 (two sliders are of uniform size limit), a base 5, a baffle 6, a mounting seat 7 and a mechanical lock device 8 (four mechanical locks are of uniform size limit) installed on the base 5. This device has four sets of electric drive motors. The first drive device slider 4 is installed on the slide rail of the base 5 and connected to the connecting rod mechanism 3, which is used to control the opening and closing brake plate 2 unit of the connecting rod mechanism 3 to achieve lifting; the second drive mechanical lock device 8 is installed inside the slide rail of the base 5, and mechanically locks the brake plate 2 when it is open and closed, so that the device remains stable during the operation of the train; the third drive device is installed at the connection between the baffle 6 and the base 5, and is located on the bearing of the base 5 to drive the baffle 6 to rotate around the axis, so that the baffle 6 is closed when the brake plate 2 is working, and blocks the brake plate 2 when the brake plate 2 is not working; the fourth drive device is installed at the connection between the base 5 and the mounting seat 7, so that the base 5 can rotate in the horizontal plane, so that the working direction of the brake device is consistent with the travel direction of the train. This device has a set of power generation devices, which are located on both sides of the cavity of the brake plate 2. When the brake plate 2 is working, the rotation of the fan blade 1 installed on the device drives the power generation device to generate electricity. The mounting seat 7 is fixed on the top of the high-speed train and is made of a light and high-strength aluminum alloy. It is connected to the base 5 through the fourth drive device, and the connection method is electromagnetic contact, so that the working direction of the wind resistance brake plate 2 is consistent with the running direction of the train. The base 5 is connected to the mounting seat 7 through the fourth drive device, and is also made of a light and high-strength aluminum alloy. There is a groove slide rail for the first drive device slider 4 and the second drive mechanical lock device 8 to slide. The slider 4 connects the connecting rod mechanism 3 and the base 5. The connection method of the slider 4 and the base 5 is electromagnetic contact. The slider 4 is connected to the connecting rod structure 3 by a rotating shaft. The slider 4 moves horizontally along the slide rail by electricity to drive the connecting rod mechanism 3 to move, thereby controlling the opening and closing of the brake plate 2. The connecting rod mechanism 3 adopts an H-shaped connecting rod, which is made of stainless steel and is a non-powered device. It is connected to the first drive device slider 4 through a rotating shaft, and moves with the sliding of the first drive device slider 4. It is connected to the brake plate 2 structure through the rotating shaft, so that the brake plate 2 follows the movement of the connecting rod mechanism 3 to realize the opening and closing of the brake plate 2 structure, and the connecting rod mechanism 3 is parallel to the roof when in the closed state. The brake plate 2 is made of aluminum alloy and is a non-powered device. It is connected to the connecting rod mechanism 3 and the base 5. It is opened and closed by the movement control of the connecting rod mechanism 3 and is connected to the fan blade 1 through the rotating power generation device on both sides of its internal cavity. The fan blade 1 is made of carbon fiber and is connected to the brake plate 2 through the power generation device on both sides of the brake plate 2. When working, the wind flows through the cavity in the middle of the brake plate 2, thereby driving the fan blade 1 to rotate, and the rotation of the fan blade 1 drives the rotating power generation device to generate energy.The baffle 6 is made of aluminum alloy and is connected to the base 5 through a third driving device. When the brake plate 2 is working, the baffle 6 is lowered to contact the plane on the base 5. When the brake plate 2 is not working, the baffle 6 is in a raised state, contacting the brake plate 2 and thus preventing wind from flowing back into the cavity of the brake plate 2. The whole set of wind resistance braking device can be realized modularly. During the normal running of the high-speed train, it is attached to the roof and is consistent with the overall appearance of the train. When the brake plate 2 needs to work, the power system controlled by the central system starts to work, the mechanical lock device 8 is unlocked, and the two sliders 4 slide synchronously in the groove slide rails of the base 5. When reaching the specified position, the mechanical lock device 8 returns to the locked state again. At the same time, the baffle 6 gradually closes from the open state until it fits with the upper plane of the base 5. At this time, wind flows through the inner cavity of the brake plate 2, driving the fan blades 1 to rotate, and then recovering energy through the power generation device; when the brake plate 2 is not needed to work, the baffle 6 gradually opens from the closed state, the mechanical lock device 8 is unlocked, and the two sliders 4 slide synchronously in the opposite direction in the groove slide rails of the base 5. When reaching the specified position, the mechanical lock device 8 returns to the locked state again. At this time, the brake plate 2 is in contact with the baffle 6 and remains parallel to the roof plane.

[0058] In this embodiment, the electric drive device is a slider 4, a mechanical lock 8, a base 5 and a baffle 6 connection device, and a base 5 and a mounting seat 7 connection device. The slider 4 drives the movement of the connecting rod mechanism 3 by sliding in the groove slide rail of the base 5, thereby controlling the opening and closing of the brake plate 2; the mechanical lock 8 is used to fix the slider 4 device in the two states of the brake plate 2 being opened and closed to maintain the stability of the structure, and the unlocked state is always maintained during the sliding process of the slider 4, and the sliding of the slider 4 is not affected; the base 5 and the baffle 6 connection device drives the baffle 6, closing the baffle 6 when the brake plate 2 is opened, and opening the baffle 6 when the brake plate 2 is closed; the base 5 and the mounting seat 7 connection device controls the rotation of the base, so that the working direction of the brake plate 2 device is consistent with the driving direction of the train.

[0059] In this embodiment, as a supporting device for the entire device, the connecting rod mechanism 3 adopts an H-shaped connecting rod to ensure that the brake plate 2 does not deviate to the sides of the train, and is made of stainless steel to provide a sufficiently high strength to support the brake plate 2.

[0060] In the example, the mounting seat 7 is installed on the roof of the vehicle, is made of aluminum alloy, is connected to the base 5 through a fourth driving device, and controls the base 5 to rotate through the driving device.

[0061] In this embodiment, the base 5 is made of aluminum alloy; the locking groove of the mechanical lock 8 is designed inside the slide rail and is kept perpendicular to the slide rail for the slider 4 to slide.

[0062] In this embodiment, the baffle 6 is made of aluminum alloy and is connected to the base 5 through a third driving device. It is closed when the brake plate 2 is opened, and is opened when the brake plate 2 is closed.

[0063] In this embodiment, the brake plate 2 is made of aluminum alloy, connected to the connecting rod mechanism 3 and the base 5, and is opened and closed by the motion control of the connecting rod mechanism 3, and is connected to the fan blade 1 through the rotating power generation device on both sides of its internal cavity. Figure 7 As shown, there are three sets of rotating power generation devices on both sides of the inner cavity of the brake plate 2, fixing the two ends of the three blades respectively. When the wind drives the blade 1 to rotate, the blade 1 transfers the angular kinetic energy of rotation to the power generation device, which converts the kinetic energy into electrical energy.

[0064] In this embodiment, the fan blade 1 is made of carbon fiber material and is connected to the brake plate 2 through power generation devices on both sides of the brake plate 2.

[0065] Example 2

[0066] A high-speed train windage brake device with energy recovery function applied to high-speed trains. Several sets of this device are installed on the roof of the train to provide resistance and recover energy when the train brakes. The device needs to be installed at a certain distance and connected to the top surface of the train through the mounting seat 7. When the train brakes, it works together. Fig.11 shown.

[0067] In this embodiment, the separate wind resistance braking device includes a fan blade 1, a brake plate 2, a connecting rod mechanism 3, a driving device slider 4, a base 5, a baffle 6, a mounting seat 7 and a mechanical locking device 8 installed on the base 5; the mounting seat 7 is installed on the top of the train, the base 5 is installed on the mounting seat 7, the slider 4 and the mechanical locking device 8 are in contact with the slide rail of the base 5 through an electromagnetic system, the two ends of the connecting rod mechanism 3 are respectively connected to the slider 4 and the brake plate 2, the baffle 6 is connected to the base 5 through the electromagnetic system, the brake plate 2 and the base 5 are connected through a rotating shaft, and the fan blade 1 is connected to the brake plate 2 through the rotating power generation devices on both sides of the inner cavity of the brake plate 2 to form a complete wind resistance braking structure.

[0068] In this embodiment, each high-speed train windage braking device shares a set of electromagnetic control systems, and can work simultaneously when the driver controls the brake plate 2 to open and close.

[0069] In this embodiment, the second driving mechanical lock device 8 locks the slider 4 only when the brake plate 2 is in a fully opened or closed state, and does not lock the slider 4 during the sliding process of the slider 4 of the first driving device.

[0070] In this embodiment, the third electric drive device connecting the base 5 and the baffle 6 is closed after the brake plate 2 is opened, and is opened before the brake plate 2 is closed.

[0071] In this embodiment, the fourth electric drive device connecting the base 5 and the mounting seat 7 is started only when the train is to run in the reverse direction, driving the base 5 to rotate and reversing the working direction of the brake plate 2 so that the running direction of the train is consistent with the working direction of the brake plate 2.

[0072] In this embodiment, the movement of the connecting rod mechanism 3 is controlled by sliding the slider 4 in two opposite directions, thereby controlling the opening and closing of the brake plate 2. When braking, the brake plate 2 is opened to generate braking resistance and recover energy.

[0073] When the high-speed train is in operation, the wind resistance braking system is in a non-operating state, and the brake plate 2 is parallel to the roof surface. When braking, the brake plate 2 needs to be opened and work, and the power system controlled by the central system starts to work, and the second drive mechanical lock device 8 is activated, and the second drive mechanical lock device 8 is unlocked and retracted into the groove of the slide rail; the first drive device slider 4 is activated, and the first drive device slider 4 slides in the slide rail. The first drive device slider 4 is connected through the rotating shaft and the connecting rod, driving the connecting rod mechanism 3 to move, and the connecting rod mechanism 3 is connected to the brake plate 2 through the rotating shaft, driving the brake plate 2 to rise; the third drive device is activated, and the third drive device drives the baffle 6 to close. When the brake plate 2 reaches the specified angle, the first drive device slider 4 stops moving, and the second drive mechanical lock device 8 re-enters the locked state. During the braking process, the wind passes through the cavity on the brake plate 2, driving the fan blade 1 to rotate, and then driving the rotating power generation devices on both sides of the brake plate 2 to recover wind energy and generate energy; when the braking is completed, the third electric drive device is activated, so that the baffle 6 starts to rotate and changes from a closed state to an open state; the second drive mechanical lock device 8 is activated, so that the second drive mechanical lock device 8 is unlocked and retracted into the groove of the slide rail; the first drive device slider 4 is activated, and the first drive device slider 4 slides in the slide rail. The first drive device slider 4 is connected by a rotating shaft and a connecting rod, driving the connecting rod mechanism 3 to move, and the connecting rod mechanism 3 is connected by a rotating shaft and the brake plate 2 to drive the brake plate 2 to descend; when the brake plate 2 is parallel to the plane of the train roof, the second drive mechanical lock device 8 enters the locked state again to keep the brake plate 2 structurally stable in the recovery state. At this time, the baffle 6 just blocks the brake plate 2 to avoid generating greater resistance and prevent damage to the wind energy recovery device inside the brake plate 2. When the train is to run in the opposite direction, the fourth electric drive device is activated to rotate the base 5 180° in the horizontal plane so that its working direction is consistent with the travel direction of the train; Figure 2 The figure shows the working state of the brake plate 2.

[0074] The utility model discloses a high-speed train windage braking device, which is used for a fixed-formation bidirectional high-speed train with a driver's cab at both ends, and can perform end-changing operations without turning around. The utility model can provide braking force for the train, recover energy at the same time, and change the direction of action according to the direction of the train's travel, so that bidirectional braking and energy recovery can be performed using one set of devices.

[0075] The train wind resistance braking device of the utility model is installed on the top of the train. Figures 11 to 13When not in operation, the device is in a stowed state to reduce the impact on the overall streamlined appearance of the train. Fig.13 shown.

[0076] When the train wind resistance brake device of the utility model is installed on the roof of a high-speed train, the installation position must be reasonably determined and arranged as follows: Figures 11 to 13 As shown, three groups are installed on the head car and the tail car respectively, and five groups are installed on the middle car.
