Description

Technical Field

[0001] The present application relates to the technical field of gravity energy storage, and in particular to a continuous gravity energy storage system. Background Art

[0002] The unstable generation of renewable energy sources such as wind and photovoltaic power can place significant pressure on grid distribution. A mismatch between renewable energy generation resources and power loads can also lead to energy waste. Energy storage systems can provide peak load and frequency regulation for renewable energy, making the integration of renewable energy storage systems an inevitable trend. Currently, the more mature energy storage technologies include battery storage, pumped hydro storage, and compressed air storage.

[0003] Gravity energy storage is a novel energy storage technology that uses excess energy to impart potential energy to objects of a certain mass and stores it, thereby storing the energy. This potential energy can then be converted back into electricity and other energy sources by releasing the object. Due to its advantages such as low cost per kilowatt-hour and flexible site selection, gravity energy storage has gradually gained attention in the energy storage field and has achieved a certain degree of application.

[0041] The following will clearly and completely describe the technical solution of this application in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of this application.

[0043] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0044] like Figures 1 to 5As shown, the present application provides a continuous gravity energy storage system, including a building module, a lifting module 01 and a plurality of weight blocks 03. The building module includes a building body and an upper storage unit and a lower storage unit each for storing the weight blocks 03. The upper storage unit and the lower storage unit are both installed on the building body.

[0045] The lifting module 01 includes a frame 09 and a lifting unit, a transport support unit 16 and a transition support unit all mounted on the frame 09.

[0046] The lifting unit is used to drive the transport support unit 16 to continuously move in the vertical direction relative to the frame 09 and the transition support unit.

[0047] The heavy object block 03 is transferred between the transport support unit 16 and the building module via the transition support unit, so as to realize the transfer of the heavy object block 03 between the upper storage unit and the lower storage unit.

[0048] The continuous gravity energy storage system provided in the present application can transmit heavy blocks 03 between the building modules and the transition support units, and the transport support unit 16 can move in the vertical direction driven by the lifting unit and can transmit heavy blocks 03 between the transition support units during this process, thereby realizing the transmission of heavy blocks 03 with the building modules without the need for the transport support unit 16 to stop moving, thereby achieving the purpose of continuously transmitting heavy blocks 03 from the lower units to the upper units to realize energy storage, and continuously transmitting heavy blocks 03 from the upper units to the lower units to realize energy release, thereby improving the energy conversion rate.

[0049] Optionally, the continuous gravity energy storage system provided in the embodiment of the present application includes two lifting modules 01 arranged in a mirror-symmetrical manner, and the two transport support units 16 in the two lifting modules 01 are used to transport the same heavy object block 03. That is to say, when transporting a heavy object block 03, one of the two transport support units 16 in a mirror-symmetrical manner is used to support one side of the heavy object block 03, and the other transport support unit 16 is used to support the other side of the heavy object block 03. In this way, by setting up two lifting modules 01 to jointly transport the heavy object block 03, the safety and reliability of the transportation process can be improved. Of course, only one lifting module 01 can be set to transport the heavy object block 03. In this case, when transporting the heavy object block 03 between the following lateral conveying assembly and the transition support block 05, the lateral conveying assembly and the transition support block 05 can be staggered to avoid interference between the lateral conveying assembly and the transition support block 05.

[0050] Optionally, the lifting unit includes a transmission assembly and a traction assembly both mounted on the frame 09, the traction assembly including a flexible traction member 22, the transmission assembly including two transmission members 10, one transmission member 10 mounted on the top end of the frame 09, and the other transmission member 10 mounted on the bottom end of the frame 09, the flexible traction member 22 extending around the frame 09, and the flexible traction member 22 and the two transmission members 10 are in transmission cooperation, and the transport support unit 16 is fixed to the flexible traction member 22, so that the transmission assembly and the flexible traction member 22 sequentially drive and drive the transport support unit 16. In the embodiment of the present application, the flexible traction member 22 is preferably a transmission chain, a conveyor belt, or a traction rope, and accordingly, the transmission member 10 can be constructed as a gear, a pulley, or a roller. In this way, the flexible traction member 22 drives the transport support unit 16 to move vertically on the frame 09. When the transport support unit 16 moves to the top or bottom of the frame 09, the transport support unit 16 moves from one side of the frame 09 to the other side along with the flexible traction member 22, thereby realizing the transport support unit 16 circulating around the frame 09, so as to achieve the purpose of transporting the heavy object 03 through the transport support unit 16. In the embodiment of the present application, preferably, the traction assembly also includes a tractor 08, and the tractor 08 includes a vehicle body, rollers and support limiting wheels. There is a vertically extending guide groove on the frame 09, and the support limiting wheel extends into the guide groove and slides with the guide groove. When the continuous gravity energy storage system adopts a structural form including two lifting modules 01 arranged in a mirror-symmetrical manner, the flexible traction members 22 in the two lifting modules 01 are moved synchronously, in the same direction and at the same speed through the transmission assembly.

[0051] like Figure 4As shown, optionally, the transport support unit 16 includes a mounting frame 20, a transport support block 19 and a first bidirectional ratchet assembly 18, the mounting frame 20 is fixedly connected to the flexible traction member 22, the transport support block 19 is installed on the mounting frame 20 through the first bidirectional ratchet assembly 18 and the first elastic reset member, the transport support block 19 is used to rotate around a horizontally arranged rotating shaft, the first bidirectional ratchet assembly 18 is used to limit the rotation direction of the transport support block 19, and the first elastic reset member is used to reset the transport support block 19 after rotation. When the transport support unit 16 passes the weight block 03 already placed on the transition support unit, the first bidirectional ratchet assembly 18 limits the transport support block 19 so that the transport support block 19 can only rotate downward under the action of the weight block 03, thereby causing the weight block 03 to separate from the transport support block 19 and fall to the transition support unit under the action of gravity. After the weight block 03 is completely separated from the transport support block 19, the transport support block 19 is reset under the action of the first elastic reset member; when the transport support unit 16 passes the weight block 03 already placed on the transition support unit from top to bottom, the first bidirectional ratchet assembly 18 limits the transport support block 19 so that the transport support block 19 can only rotate downward under the action of the weight block 03. When the transport support block 19 is moved to the bottom of the heavy object block 03, it returns to its original position under the action of the first elastic reset member, and the transition support unit releases the heavy object block 03. The transport support block 19 below receives and supports the heavy object, and then carries out the subsequent transportation process of the transport support block 19. Similarly, when the transport support unit 16 passes from top to bottom the heavy object block 03 that has been placed on the transition support unit, the first two-way ratchet assembly 18 can also be used to limit the transport support block 19 so that the transport support block 19 can only rotate downward, thereby realizing the avoidance of the transport support block 19 to the heavy object block 03, so that the transport support unit 16 can pass smoothly. In the embodiment of the present application, preferably, two flexible traction members 22 are arranged side by side on the frame 09 in the horizontal direction, and the two mounting brackets 20 are fixedly connected to the two flexible traction members 22 in a one-to-one correspondence. When the traction assembly includes the above-mentioned tractor 08, the two mounting brackets 20 are fixedly connected to the two tractor 08 in a one-to-one correspondence. In the embodiment of the present application, the elastic return member can be a spring, a spring, or other components.

[0052] Optionally, the transport support unit 16 further includes a damping support member 21, the top end of which is pivotally connected to the transport support block 19, and the bottom end of which is pivotally connected to the mounting bracket 20. In this embodiment of the present application, the damping support member 21 is preferably a damping cylinder. The provision of the damping support member 21 can provide a certain degree of cushioning for the rotation of the transport support block 19, thereby preventing collision between the transport support block 19 and the mounting bracket 20.

[0053] Optionally, the transition support unit includes a second bidirectional ratchet assembly 17 and a transition support block 05, and the transition support block 05 is installed on the frame 09 through the second bidirectional ratchet assembly 17 and a second elastic reset member. The transition support block 05 is used to rotate around a horizontally arranged rotating shaft, the second bidirectional ratchet assembly 17 is used to limit the rotation direction of the transition support block 05, and the second elastic reset member is used to reset the transition support block 05 after rotation. When the transport support unit 16 moves below the transition support unit 16, the second two-way ratchet assembly 17 changes the limiting direction of the transition support block 05, so that the transition support block 05 can rotate downward under the action of the weight block 03, thereby causing the weight block 03 to separate from the transition support block 05 under the action of gravity and fall to the transport support unit 16 (specifically, it can fall to the transport support block 19). After the weight block 03 is completely separated from the transition support block 05, the transition support block 05 is reset under the action of the second elastic reset member; when the transport support unit 16 moves from bottom to top with the weight block 03 passing through the transition support block 05, The second two-way ratchet assembly 17 is controlled to limit the transition support block 05 so that the transition support block 05 can only rotate upward but not downward, so that when the heavy object block 03 contacts the transition support block 05, the transition support block 05 gradually rotates upward under the action of the heavy object block 03 to avoid the heavy object block 03. When the heavy object block 03 passes the position of the transition support block 05 and is completely separated from the transition support block 05, the transition support block 05 is reset under the action of the second elastic reset member; similarly, when the transport support unit 16 moves from top to bottom with the heavy object block 03 passing through the transition support block 05, the second two-way ratchet assembly 17 is controlled to limit the transition support block 05 so that the transition support block 05 can only rotate downward but not upward, thereby achieving avoidance of the heavy object block 03 and allowing the heavy object block 03 to pass smoothly. In an embodiment of the present application, preferably, the transition support unit includes two transition support blocks 05, both of which are connected to the second bidirectional ratchet assembly 17, and the two transition support blocks 05 are arranged along the axial direction of the rotating shaft and are arranged on both sides of the transport support unit 16; preferably, a damping support member 21 is passed between the transition support block 05 and the frame 09, thereby buffering the rotation of the transition support block 05.

[0054] In the embodiment of the present application, the first two-way ratchet assembly 18 and the second two-way ratchet assembly 17 both include electric two-way ratchet mechanisms, which are electrically reversed. In the embodiment of the present application, the first two-way ratchet assembly 18 and the second two-way ratchet assembly 17 can be replaced by electric motors.

[0055] Optionally, the lifting module 01 includes a plurality of transport support units 16, each of which is evenly distributed along the extension direction of the flexible traction member 22. When the frame 09 is relatively high, the plurality of transport support units 16 facilitates continuous and efficient transport of the heavy object 03. Of course, when the frame 09 is relatively low, the lifting module 01 may also include only one transport support unit 16, and the transport support unit 16 may be moved rapidly to achieve continuous transport of the heavy object 03.

[0056] Optionally, the lifting module 01 includes multiple transition support units, the building module includes multiple upper storage units arranged in the vertical direction and multiple lower storage units arranged in the vertical direction, each of the transition support units is an upper transition support unit 11 and a lower transition support unit 12, the number of the upper transition support units 11 is the same as the number of the upper storage units, and the position of each upper transition support unit corresponds one-to-one to the position of each upper storage unit in the vertical direction, the number of the lower transition support units 12 is the same as the number of the lower storage units, and the position of each lower transition support unit corresponds one-to-one to the position of each lower storage unit in the vertical direction. In this way, the heavy objects 03 can be transferred simultaneously between each upper transition support unit 11 and each upper storage unit, the heavy objects 03 can be transferred simultaneously between each upper transition support unit 11 and each transport support unit 16, the heavy objects 03 can be transferred simultaneously between each lower transition support unit 12 and each lower storage unit, and the heavy objects 03 can be transferred simultaneously between each lower transition support unit 12 and each transport support unit 16, thereby improving the transportation efficiency of the heavy objects 03. Of course, the number of upper transition support units 11 can be greater than the number of upper storage units, and the number of lower transition support units 12 can be greater than the number of lower storage units.

Of course, the number of transport support units 16 in a lifting module 01 may also be no more than the number of transition support units, and / or the number of transport support units 16 in a lifting module 01 may also be no more than the sum of the number of upper storage units and the number of lower storage units.
