Description

TECHNICAL FIELD

[0001] The utility model relates to railway machinery technical field, concretely relates to a railway train self -power generation device. BACKGROUND

[0002] In the field of railway transportation, with the continuous progress of technology and the increasing demand for heavy haul transportation, the further improvement of train marshalling and gross tonnage puts forward higher requirements for the safety and reliability of train operation. Among them, the ECP brake system (Electronically Controlled Pneumatic Brake, electronically controlled pneumatic brake) as a key component of modern train braking technology, its efficient and accurate braking performance is essential to ensure the safety of train braking under the condition of high speed and heavy load. The wide application of ECP brake system depends on stable and reliable power supply, however, the traditional method of relying only on battery power supply has been difficult to meet the current power demand of train long time operation and complex operation environment. The endurance of the battery is limited, it is difficult to ensure the normal operation of ECP brake system and other on-board electronic equipment in a complete maintenance cycle, at the same time, the low discharge power of the battery also limits the economy and practicability of locomotive direct power supply.

[0003] In addition, with the improvement of intelligentization and informatization level of railway transportation, the functions of vehicle operation state monitoring, safety warning, accurate positioning, cold chain transportation control and temperature management of refrigerated container are increasingly rich, and the realization of these functions cannot be separated from stable power support. Therefore, how to provide continuous and reliable power supply for train has become an important bottleneck to promote the modernization development of railway freight transportation.

[0004] In view of the above problems, the kinetic energy generated in the process of train running is used for self power generation, which is an innovative idea to solve the problem of train power supply. This scheme not only can reduce the dependence on external power supply, improve the self-sufficiency ability of train, but also can optimize the energy utilization structure and reduce the operation cost while ensuring the safe operation of train. However, most of the power generation equipment in the current market cannot effectively integrate vehicle kinetic energy conversion and efficient power management technology, that is, in the process of train running, the kinetic energy is converted into electric energy by self power generation device, and after the voltage stabilization and rectification treatment of power management system, on the one hand, the standby battery is charged to ensure that the battery is used as standby power source for power supply in the state of low speed running or parking; On the other hand, stable power is directly provided for various loads on the train.

[0005] In summary, it is of great significance to develop a kind of comprehensive power generation equipment which can efficiently utilize the kinetic energy of train running, integrate self power generation, power management, energy storage and power supply, and improve the energy efficiency, safety and intelligent level of railway freight transportation. It is an urgent need for the development of current railway freight technology. Practical new type content

Figures 1-3 As shown, the system includes a first hydraulic drive assembly 1, a first conical wheel 2, a second hydraulic drive assembly 3, a second conical wheel 4, a transmission track 5, a power generation assembly 6, and a mounting frame 7. The first hydraulic drive assembly 1 is coaxially connected to the axle of the external wheel. When the external wheel rotates, it drives the first hydraulic drive assembly 1 to rotate. Simultaneously, it is coaxially connected to the first conical wheel 2, forming a first compression space. The width of this first compression space can be adjusted, which in turn adjusts the engagement position of the transmission track 5. A larger width results in a lower engagement position, equivalent to engaging a small gear; a smaller width results in a higher engagement position, equivalent to engaging a large gear. The size of the engaged gear can be adjusted according to actual power generation needs to ensure continuous and stable power generation. The first conical wheel 2 is coaxially opposite to the first hydraulic drive assembly 1, forming the first compression space. Under the compression of both, it restricts the transmission track 5, preventing it from slipping and ensuring stable rotation of the transmission track 5. The second hydraulic drive assembly 3 is rotatably mounted on the mounting frame 7, coaxially connected to the second conical wheel 4, and forms a second compression space with the second conical wheel 4. The width of the second compression space can be adjusted, which adjusts the engagement position of the transmission track 5. If the width is large, the engagement position is low, which is equivalent to engaging a small gear; if the width is small, the engagement position is high, which is equivalent to engaging a large gear. The size of the engaged gear can be adjusted according to the actual power generation needs to ensure continuous and stable power generation. The second conical wheel 4 is coaxially arranged with the second hydraulic drive assembly 3, forming the second compression space. Under the compression of both, it can restrict the transmission track 5, preventing it from slipping and ensuring stable rotation of the transmission track 5. The transmission track 5 is fitted onto the first and second compression spaces and is used to drive the second conical wheel 4 to rotate with the rotation of the first conical wheel 2. Preferably, it is made of a hard material, such as an alloy or metal, preferably steel, with a certain degree of hardness.
