Description

Technical Field

[0001] This application relates to the field of energy storage technology, and in particular to a multi-power section gravity energy storage rail cable car transportation system. Background Technology

[0002] When power generation exceeds electricity consumption, the generated energy needs to be stored so that it can be effectively released during periods of high electricity demand. Using this stored energy to supply power effectively utilizes the power generated by the equipment. The generated energy can be converted into other types of energy for storage. Against the backdrop of the global energy structure transitioning to clean energy, energy storage technology, as a key support for balancing intermittent renewable energy and grid stability, is becoming increasingly important. Gravity energy storage technology, with its advantages of low cost, long lifespan, and environmental friendliness, has become one of the current research hotspots in the energy storage field. Cable car systems are widely used due to their adaptability to complex terrain. Therefore, developing a cable car transportation system that can adapt to mountainous terrain with multiple elevation differences and combines gravity energy storage technology to achieve efficient power output and energy recovery is crucial to solving the aforementioned technical challenges.

Those skilled in the art should understand that this application can be implemented without certain specific details. In some instances, methods, means, components, and circuits well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0040] like Figure 1 and Figure 2As shown, the multi-segment gravity energy storage rail cable car transportation system of this application embodiment includes: a transport track 10, a support frame 40, an excitation motor 20, a cable 50, and a transport trolley 30; the transport track 10 has a multi-segment structure, suitable for being laid sequentially on a mountain; the support frame 40 is set between any two adjacent transport tracks 10; the excitation motor 20 is set on the support frame 40; the transport trolley 30 is slidably set on the transport track 10; the cable 50 has a multi-segment structure, is tractably set on the transport track 10, and the cable 50 is drivenly connected to the excitation motor 20 and the transport trolley 30.

[0041] In this specific embodiment, there is a height difference between the mountaintop and the bottom. When a transport trolley 30 is used to transport heavy objects on the transport track 10, a potential energy difference is generated when transporting from the mountaintop to the bottom. Therefore, the potential energy generated by the transport trolley 30 carrying heavy objects as it slides from the mountaintop to the bottom can be collected and converted into electrical energy to power the operation of the transport track 10. Specifically, a support frame 40 is provided between the multiple sections of the transport track 10 to house the generator and to provide a turning point for the closed-loop cable 50. A closed-loop cable 50 is provided on any section of the transport track 10. The cable 50 is connected to the excitation motor 20 to provide power for the transport trolley 30 to go uphill and for the transport trolley 30 to go downhill while holding the cable 50 and connecting it to the excitation motor 20, through which the kinetic energy is converted into electrical energy.

[0042] In one specific embodiment, the transport track 10 has a multi-segment structure, and the number of cables 50 corresponds one-to-one with the number of transport tracks 10. Each segment of the transport track 10 is equipped with a corresponding cable 50, enabling each segment to form an independent power transmission and energy conversion unit. Specifically, each segment of the transport track 10 corresponds to a closed-loop cable 50 and an excitation motor 20. The loop cable 50 is respectively sleeved on the support frames 40 at both ends of the transport track 10, and either end is driven and connected to the excitation motor 20. When going uphill, the excitation motor 20 drives the cable 50 to pull the transport trolley 30, and when going downhill, the transport trolley 30 pulls the cable 50 to supply power to the excitation motor 20.

[0043] In one specific embodiment, the cable 50 is a closed-loop loop, allowing it to continuously circulate on the transport track 10 without frequent connection and disconnection. Driven by the closed-loop cable 50, the transport trolley 30 can achieve bidirectional transport, meaning it can transport goods both downwards from the top of the mountain and upwards from the bottom. Simultaneously, the closed-loop cable 50 structure helps improve the stability and efficiency of energy transmission, facilitating energy recovery and release by the excitation motor 20 during the bidirectional movement of the transport trolley 30.

[0044] In one specific embodiment, the support frame 40 includes three parts: a top rotating bracket, a mounting bracket, and a bottom rotating bracket. The mounting bracket is set between any two adjacent transport tracks 10, and the excitation motor 20 is set on the mounting bracket. The mounting bracket enables the stable installation of the excitation motor 20 and its connection with the cable 50. The top slewing bracket is located at the top of the mountain. One end of a cable 50 is wound around the top slewing bracket via a pulley, and the other end is wound around the mounting bracket via a pulley, connecting to the excitation motor 20 for drive. The mounting bracket ensures the stable installation of the excitation motor 20 and its connection with the cable 50. The bottom slewing bracket is located at the bottom of the mountain. One end of a cable 50 is wound around the bottom slewing bracket via a pulley, and the other end is wound around the mounting bracket via a pulley, connecting to the excitation motor 20 for drive. The top and bottom slewing brackets enable the cable 50 to turn at the top and bottom of the mountain, allowing the cable 50 to form a complete transmission line along the height difference of the mountain. Together with the mounting bracket and the excitation motor 20, this enables energy transfer and conversion between multiple power segments.

[0045] In one specific embodiment, the mounting bracket includes a frame, a third pulley, a fourth pulley, a fifth pulley, and a sixth pulley. The frame has a hollow structure with an excitation motor 20 mounted on its exterior. The top of the frame is tilted, with the tilt angle matching the slope of the mountain. The hollow structure facilitates the arrangement of the cable 50 and the installation of the pulleys, while also reducing the weight of the mounting bracket. The tilted top of the frame, with its angle matching the slope of the mountain, allows the mounting bracket to better adapt to the terrain, ensuring that the transmission direction of the cable 50 is consistent with the slope of the mountain, thus improving transmission efficiency.

[0046] There are two third pulleys, which are rotatably set at the top of the frame. The two third pulleys rotate in the same direction, matching the slope of the mountain, and are used to guide the transmission direction of the cable 50 at the top of the frame, so that it moves along the slope of the mountain.

[0047] There are two fourth pulleys, which are rotatably set at the top and bottom of the frame. The two fourth pulleys rotate in the same direction, matching the slope direction of the mountain, and guiding the transmission direction of the cable 50 at the top and bottom of the frame.

[0048] There are two fifth pulleys, which are set inside the frame and are respectively set above and below the two third pulleys. The two fifth pulleys rotate in the same direction. The plane of rotation of the third pulley is perpendicular to the plane of rotation of the fifth pulley, so that the cable 50 can change direction when passing through the third pulley and the fifth pulley, which can adapt to the internal structure of the mounting bracket and the transmission requirements of the cable 50.

[0049] The sixth pulley is rotatably mounted inside the frame, corresponding to the excitation motor 20 and the fourth pulley respectively. One end of one cable 50 is wound around the third and fifth pulleys, and the other end of one cable 50 is wound around the fourth pulley, the sixth pulley and the excitation motor, realizing the driving connection between the cable 50 and the excitation motor 20, so that the excitation motor 20 can effectively convert the energy of the cable 50.

[0050] In one specific embodiment, there are multiple sixth pulleys, all of which are located inside the frame and correspond to the excitation motor 20 and the fourth pulley, respectively. The arrangement of multiple sixth pulleys can better guide the direction of the cable 50, so that the cable 50 is subjected to more uniform force when connected to the excitation motor 20, thereby improving the stability and reliability of the connection. At the same time, it can also adapt to the needs of cables 50 with different specifications and tensile strengths.

[0051] In one specific embodiment, the bottom rotating support includes: a bottom support, a first pulley, and a second pulley; the bottom support has a hollow structure with a square cross-section. The hollow structure facilitates the installation of the pulley and the arrangement of the cable 50, while the square cross-section ensures the structural strength of the bottom support.

[0052] The system comprises two first pulleys, rotatably mounted inside the bottom support. The rotation of the first pulleys is tangential to the length of the transport track 10, and both pulleys rotate in the same direction, guiding the cable 50 along the length of the transport track 10 within the bottom support. Similarly, two second pulleys are rotatably mounted outside the bottom support, also rotating in the same direction. The plane of rotation of the first pulleys is perpendicular to the plane of rotation of the second pulleys, and the two first and second pulleys are arranged in a rectangular configuration. One end of the cable 50 is wrapped around the first and second pulleys, allowing the cable 50 to turn vertically at the bottom support. The rotation of the pulleys enables the cable 50 to turn and move along the bottom of the mountain.

[0053] In one specific embodiment, the structure of the top slewing bracket is the same as that of the bottom slewing bracket.

Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
