Description

Technical Field

[0001] The present invention belongs to the technical field of gravity energy storage, in particular to a gravity energy storage frame structure and a gravity energy storage system thereof. Background Art

[0002] In the construction of a new power system with new energy as the main body, new energy represented by wind and solar power is of great importance; however, due to the inherent characteristics of wind and solar power generation, the basic requirements of electricity for power and capacity balance cannot be met in the new power system with them as the main body. From the perspective of energy security, they cannot be an independent energy source and must be combined with energy storage with time and space transfer characteristics to realize power transfer and power support functions.

[0003] A Chinese patent with publication number CN115450870A discloses a gravity energy storage frame structure and its gravity energy storage system. The storage layer frame includes a storage area frame and a storage layer lifting channel frame installed and connected to the auxiliary lifting unit frame. The storage area frame includes a number of storage layer columns distributed in an array in the Z direction. Each storage layer column is installed with a number of mounting frames for installing transfer device guide rails and gravity block support beams at intervals in the Z direction, which are used to form multiple X-direction storage layer channels or multiple Y-direction storage layer channels. The transfer device guide rails extend through their corresponding X-direction storage layer channels and Y-direction storage layer channels; the space between every four adjacent mounting frames forms a gravity block storage area unit for accommodating gravity blocks, and the transfer device guide rails can be relatively displaceably installed with a transfer device and extend to the storage layer lifting channel frame for converting the transfer direction of the gravity blocks; the overall frame structure has few joints, simple process, easy control and maintenance of the overall size, and long service life.

[0004] In the current existing technology, the gravity blocks are quickly transported through the frame structure. However, in actual applications, since the frame structure does not have a limiting structure, when the gravity blocks are transported by lifting equipment, the gravity blocks will shake during control. If the position of one of the gravity blocks is offset, the positions of other gravity blocks will be offset, causing the crane to grab the gravity block again and may not find the corresponding position. In addition, there are many channels. If the gravity block is misplaced, it is inconvenient to transport it through the set channel.

DETAILED DESCRIPTION

[0033] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0034] like Figures 1 to 8As shown, a gravity energy storage frame structure according to an embodiment of the present invention comprises: two energy storage buildings 1, respectively arranged at the top and bottom of the mountain; two feeding frames 2, respectively fixed to the side walls of the energy storage building 1; a transfer structure 3 is provided in the energy storage building 1, and the transfer structure 3 comprises six pads 31 fixed to the inner wall of the energy storage building 1, and a second conveyor belt 32 is provided in the middle of each pad 31, wherein the bottoms of the five pads 31 on the top are symmetrically fixed to two first slide rails 33; the two slide rails are slidably connected to each other. The second slide rail 34 is slidably connected to a slider 35, the bottom of the slider 35 is fixedly connected to a cylinder 37, and the bottom of the cylinder 37 is provided with a clamping mechanism; a lifting plate 29 is provided in the conveying frame 2, and a first conveyor belt 25 is provided on the outer side of the lifting plate 29; six conveying channel openings 21 are opened on the side wall of the conveying frame 2 close to the energy storage building 1, and the conveying channel openings 21 are connected to the energy storage building 1, and the bottom of the conveying channel opening 21 is horizontally aligned with the top of the second conveyor belt 32.

[0035] The energy storage building 1 and the feed frame 2 provided by the present invention are used for the orderly transportation of gravity blocks when in use. The gravity block energy storage building 1 is constructed on the upper and lower sides of the steep mountain respectively. When the power grid is in a low valley or photovoltaic and wind power generation is in excess, the gravity blocks at the bottom need to be lifted to the energy storage building 1 at the top of the mountain, and the surplus electrical energy is converted into the gravitational potential energy of the heavy objects for storage and standby use. By opening the first conveyor belt 25 and the second conveyor belt 32, the gravity blocks on the second conveyor belt 32 are transported to the first conveyor belt 25 in the feed channel opening 21, and the gravity blocks on the first conveyor belt 25 are clamped by the electric slide rail and the clamping claw 62 on the lifting equipment body 6 and transported to the feed frame 2 at the top of the mountain. The first conveyor belt 25 in the feed frame 2 at the top of the mountain transports the gravity blocks to the second conveyor belt 32. Through the cooperation of the first slide rail 33 and the second slide rail 34, the gravity blocks are arranged in order on the pad 31 of the first layer. After the pad 31 is placed, the remaining gravity blocks are kept on the second conveyor belt 32.

[0036] When the weight blocks on the second conveyor belt 32 at the bottom of the mountain are transported, the weight blocks on the pad 31 can be placed on the second conveyor belt 32 in sequence through the cooperation of the first slide rail 33 and the second slide rail 34; when the weight blocks on the first layer are transported, the first conveyor belt 25 needs to be moved upward by the lifting plate 29 until the first conveyor belt 25 is horizontally aligned with the second conveyor belt 32 on the second layer, and then the movement can be stopped to maintain the continuous supply of weight blocks; at this time, the first conveyor belt 25 at the top of the mountain also needs to rise and align with the corresponding second conveyor belt 32;

[0037] When electricity consumption is at its peak, the gravity blocks at the top of the mountain are placed in order in the energy storage building 1 at the bottom of the mountain, and the gravitational potential energy stored above the top of the mountain is converted into mechanical energy and electrical energy, thereby realizing the storage and recycling of electricity;

[0038] By setting up the feeding frame 2, each time the gravity block is taken out of the feeding frame 2 or placed in the feeding frame 2, the gravity block is transported in an orderly manner through the same feeding frame 2 and the feeding channel 21. Gravity energy storage does not involve chemical reactions in the work processes such as heavy object transportation, potential energy storage, and mechanical energy generation, and its operation is safe and reliable. Gravity energy storage power generation is clean and low-carbon, with little impact on the natural environment.

[0039] The gravity blocks are made of concrete or local materials as the main material, or other recycled materials, and can be recycled for decades. The gravity blocks have little loss during operation, and it is easier to obtain local materials in mountainous environments. The cost of gravity blocks can be greatly reduced, the energy storage time is long, and there is no self-discharge problem. The storage space for the upper and lower weight blocks is open and the stacking is flexible. There is no loss during the storage of potential energy of the gravity blocks, and it has convenient conditions and advantages for long-term energy storage.

[0040] like Figures 5 to 7 As shown, the clamping mechanism includes a mounting plate 36 fixed to the output end of the cylinder 37, and the four corners of the mounting plate 36 are rotatably connected to a rotating rod 361 through a rotating shaft, the top of the rotating rod 361 is fixed to a second rotating wheel 364, and the bottom of the rotating rod 361 is fixed to a limiting plate 362, wherein a second belt 365 is sleeved between two adjacent second rotating wheels 364; four sleeves 363 are fixed to the bottom of the mounting plate 36, and the sleeves 363 are all arranged on the outside of the rotating rod 361; two L-shaped plates 366 are fixed to the top of the mounting plate 36, and a second motor 367 is fixed to the L-shaped plate 366, and the output shafts of the second motor 367 are respectively fixed to the tops of the two rotating rods 361 on the same side.

[0041] When the limit plate 362 provided by the present invention is in use, the weight block conveyed by the second conveyor belt 32 is moved to the top of the weight block by the first slide rail 33 and the second slide rail 34, and the mounting plate 36 is moved downward by the cylinder 37 until the limit plate 362 contacts the second conveyor belt 32 and stops moving. By turning on the second motor 367, the output shaft of the second motor 367 drives the connected rotating rod 361 to rotate, and the rotating rod 361 drives the connected second rotating wheel 364 to rotate. The second rotating wheel 364 drives another second rotating wheel 364 to rotate through the second belt 365, and drives the connected rotating rod 361 to rotate through the second rotating wheel 364. The two rotating rods 361 rotate at the same time, driving the limiting plate 362 to rotate. The rotating plate cooperates with the gravity block to limit and fix the gravity block between the sleeve 363, and move the gravity block to the set position; although part of the gravity block is offset due to the influence of the lifting equipment body 6, the gravity block can also be grabbed with the cooperation of the limiting plate 362 and the sleeve 363.

[0042] like Figure 3 and Figure 4 As shown, four fixed plates 22 are fixedly connected to the top inner wall of the feed frame 2, and two of the fixed plates 22 are rotatably connected to the reciprocating screw rods 23 through bearings. Both ends of the lifting plate 29 are threadedly connected to the reciprocating screw rods 23, and the bottom of one of the reciprocating screw rods 23 is rotatably connected to the bottom inner wall of the feed frame 2 through a bearing. The bottom of the other reciprocating screw rod 23 is provided with a first motor 28, and the bottom of the first motor 28 is fixed to the bottom inner wall of the feed frame 2; the bottom end of the reciprocating screw rod 23 is fixedly connected to the first rotating wheel 26, and a first belt 27 is sleeved between the two first rotating wheels 26.

[0043] When the reciprocating screw 23 provided by the present invention is in use, the first motor 28 is turned on, and the connected reciprocating screw 23 is driven to rotate by the output shaft of the first motor 28, and the connected first rotating wheel 26 is driven to rotate by the reciprocating screw 23, and the first rotating wheel 26 drives another first rotating wheel 26 to rotate through the first belt 27, and the first rotating wheel 26 drives the connected reciprocating screw 23 to rotate, and the two reciprocating screws 23 rotate at the same time, driving the lifting plate 29 to move back and forth, and the first conveyor belt 25 is driven to move back and forth by the lifting plate 29. By adjusting the first conveyor belt 25 to be horizontally aligned with the second conveyor belt 32, the stable transportation of gravity blocks on each layer is guaranteed.

[0044] like Figure 4 As shown, the other two fixed plates 22 are fixed with guide rods 24 , the bottoms of the guide rods 24 are fixed to the bottom inner wall of the feeding frame 2 , and the lifting plate 29 is slidably connected to the two guide rods 24 .

[0045] When the guide rod 24 provided by the present invention is in use, the lifting plate 29 slides on the guide rod 24 during the movement, and the guide rod 24 limits the lifting plate 29 in the vertical direction.

[0046] like Figure 2 As shown, a lifting device body 6 is provided on one side of the upper feeding frame, and the lifting device body 6 is fixed to the mountain through anchor rods. The lifting device body 6 includes a lifting tower body 64 and a cantilever 61, and the cantilever 61 is symmetrical about the lifting tower body 64; the cantilever 61 is slidably connected with a clamp 62 through an electric slide rail.

[0047] When the cantilever 61 and the clamp 62 provided by the present invention are in use, by setting the movement trajectory of the clamp 62 on the cantilever 61 in the computer program, the electric slide rail facilitates the control of the position of the clamp 62, facilitates the adjustment of the position of the gravity block relative to the cantilever 61, and facilitates the adjustment of the position of the gravity block.

[0048] like Figure 8 As shown, the lifting equipment body 6 also includes a connecting seat 63 and a rotating block 65; the lifting tower body 64 is fixedly connected to the top of the rotating block 65; a cavity is opened in the connecting seat 63; a third motor 68 is fixedly connected to the bottom inner wall of the cavity, and the output shaft of the third motor 68 is fixedly connected to the second gear 67; a first gear 66 is fixedly connected to the rotating block 65, and the first gear 66 is engaged with the second gear 67.

[0049] When the first gear 66 and the second gear 67 provided by the present invention are in use, it is necessary to rotate the lifting tower body 64. By turning on the third motor 68, the output shaft of the third motor 68 drives the second gear 67 to rotate, and the second gear 67 drives the first gear 66 to rotate, and the first gear 66 drives the rotating block 65 to rotate, and the rotating block 65 drives the lifting tower body 64, the cantilever 61 and the gravity block to rotate, thereby realizing the angle adjustment of the lifting tower body 64, which is convenient for transporting the energy storage building body 1 at the top of the mountain and the energy storage building body 1 at the bottom of the mountain to each other.

[0050] like Figures 1 to 2 As shown, the mountain between the two energy storage buildings 1 is provided with a slope, and the slope of the slope is not less than 75°.

[0051] When the slope provided by the present invention is in use, the height difference is the core parameter of gravity energy storage. Under the condition of meeting the mountain slope requirements, a larger natural height difference can be easily obtained by selecting a mountainous environment. Under the condition of the same weight of heavy objects, the energy storage capacity is increased, thereby reducing the unit investment level and the cost per kilowatt-hour. There is no need to build large high-rise towers, and the structure is more stable, safe and reliable.

[0052] like Figure 9As shown, a gravity energy storage frame structure gravity energy storage system includes a control unit, an energy conversion unit, a photovoltaic power generation unit 4 and a wind power generation unit 5, wherein the photovoltaic power generation unit 4 includes a solar panel 41, and the wind power generation unit 5 includes a blade 51. The photovoltaic power generation unit 4 is electrically connected to the control unit for absorbing light energy to generate electricity; the wind power generation unit 5 is electrically connected to the control unit for wind energy storage and power generation; the energy conversion unit is connected to the two energy storage buildings 1 through a signal, and the energy conversion unit is used for mutual conversion between electrical energy and gravitational potential energy; the energy conversion unit and the control unit are electrically connected to the lifting equipment body 6 respectively; the control unit transports the gravity block by controlling the lifting equipment body 6.

[0053] When the control unit and energy conversion unit provided by the present invention are in use, gravity block energy storage buildings 1 are respectively constructed on the upper and lower sides of a steep mountain. When the power grid is at a low point or photovoltaic and wind power generation is in excess, the control unit drives the lifting device main body 6 to lift the gravity block at the bottom of the mountain to the energy storage building 1 at the top of the mountain, and converts the surplus electrical energy into the gravitational potential energy of the heavy object and stores it for later use. When electricity consumption is at a peak, the gravity block falls, and the gravitational potential energy of the energy storage building 1 on the top of the mountain is converted into mechanical energy and electrical energy, thereby realizing the storage and recycling of electricity.

[0054] Working principle: gravity block energy storage buildings 1 are built on the upper and lower sides of the steep mountain. When the power grid is in a low valley or photovoltaic and wind power generation is in excess, the gravity blocks at the bottom need to be lifted to the energy storage building 1 at the top of the mountain to convert the surplus electrical energy into the gravitational potential energy of the heavy objects for storage and standby use. By turning on the first conveyor belt 25 and the second conveyor belt 32, the gravity blocks on the second conveyor belt 32 are transported to the first conveyor belt 25 in the feed frame 2 through the feed channel opening 21. The gravity blocks on the first conveyor belt 25 are clamped by the electric slide rail and the clamping claw 62 on the lifting equipment body 6 and transported to the feed frame 2 at the top of the mountain. The first conveyor belt 25 in the feed frame 2 at the top of the mountain transports the gravity blocks to the second conveyor belt 32. Through the cooperation of the first slide rail 33 and the second slide rail 34, the gravity blocks are arranged in order on the pad 31 of the first layer. The pad 31 After the weight blocks are placed on the top, the remaining weight blocks can be kept on the second conveyor belt 32; when the weight blocks on the second conveyor belt 32 at the bottom of the mountain are transported, the weight blocks on the pad 31 can be placed on the second conveyor belt 32 in sequence through the cooperation of the first slide rail 33 and the second slide rail 34; after the weight blocks on the first layer are transported, it is necessary to move the first conveyor belt 25 upward through the lifting plate 29 until the first conveyor belt 25 is horizontally aligned with the second conveyor belt 32 of the second layer, and then the movement can be stopped to maintain a continuous supply of weight blocks; at this time, the first conveyor belt 25 at the top of the mountain also needs to rise and be aligned with the corresponding second conveyor belt 32; when electricity consumption is at a peak, the weight blocks at the top of the mountain can be placed in order in the energy storage building 1 at the bottom of the mountain, so that the stored gravitational potential energy above the top of the mountain is converted into mechanical energy and electrical energy, thereby realizing the storage and recycling of electricity;

[0055] The weight block transported by the second conveyor belt 32 is moved by the first slide rail 33 and the second slide rail 34 to the top of the weight block, and the mounting plate 36 is moved downward by the cylinder 37 until the limit plate 362 contacts the second conveyor belt 32 and stops moving. The second motor 367 is turned on and the output shaft of the second motor 367 drives the connected rotating rod 361 to rotate, and the rotating rod 361 drives the connected second rotating wheel 364 to rotate. The second rotating wheel 364 drives another second rotating wheel 364 to rotate through the second belt 365, and the connected rotating rod 361 is rotated through the second rotating wheel 364. The two rotating rods 361 rotate at the same time, driving the limit plate 362 to rotate. The rotating plate cooperates with the weight block to limit and fix the weight block between the sleeves 363. The gravity block moves to the set position; although part of the gravity block is offset due to the influence of the lifting device body 6, the gravity block can also be grabbed with the cooperation of the limit plate 362 and the sleeve 363; turn on the first motor 28, and the connected reciprocating screw 23 is driven to rotate by the output shaft of the first motor 28, and the connected first rotating wheel 26 is driven to rotate by the reciprocating screw 23, and the first rotating wheel 26 drives another first rotating wheel 26 to rotate through the first belt 27, and the first rotating wheel 26 drives the connected reciprocating screw 23 to rotate, and the two reciprocating screws 23 rotate at the same time, driving the lifting plate 29 to move back and forth, and driving the first conveyor belt 25 to move back and forth through the lifting plate 29, and by adjusting the first conveyor belt 25 to be horizontally aligned with the second conveyor belt 32, it is ensured that the gravity blocks are stably transported on each layer.
