Description

Technical Field

[0001] This invention relates to the field of energy storage equipment technology, and in particular to a gravity energy storage device for non-fossil energy in barren mountains. Background Technology

[0002] Gravity energy storage is a mechanical energy storage technology that uses electricity to lift heavy objects to a high place to store potential energy, and then releases the heavy objects during peak electricity demand to drive generators to generate electricity. Its energy storage medium includes solid materials and water, and it realizes the conversion of electrical energy and gravitational potential energy through the vertical height difference.

[0003] Existing gravity energy storage technologies, such as CN202211497171.0 which discloses a pyramid-shaped gravity energy storage system, use a pyramid-shaped support structure with multiple motors in the middle to move gravity blocks up and down for energy storage. However, the motors operate independently, often resulting in them running idle during energy storage or release. When centralized power generation is needed, after the motors lower the gravity blocks, the bridge box needs to be individually retracted to the top before lowering the gravity blocks again. Similarly, when centralized energy storage is needed, after the motors move the bridge box and gravity blocks to the top and remove the gravity blocks, the bridge box needs to be individually lowered to the bottom before reinstalling the gravity blocks for energy storage. This leads to increased equipment wear and the number of devices required, as well as increased energy consumption. Summary of the Invention

[0029] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0030] like Figures 1 to 6 As shown, this embodiment of the invention provides a gravity energy storage device for non-fossil energy sources in barren mountains. The device includes:

[0031] The outer retaining wall 4 is a circular structure;

[0032] A supporting component is disposed within the outer retaining wall 4;

[0033] The shaft component includes a first shaft 21 and a second shaft 22, wherein the first shaft 21 is connected to the lower part of the support component and the second shaft 22 is connected to the lower part of the support component;

[0034] The energy storage mechanism includes a first pulley assembly, a second pulley assembly, a drive component 33, a winch assembly, and a counterweight assembly 35. The first pulley assembly is located in the first vertical shaft 21, and the second pulley assembly is located in the second vertical shaft 22. The counterweight assembly 35 is detachably connected to the lower part of the first pulley assembly or the second pulley assembly. The drive component 33 is connected to the winch assembly, and the winch assembly is connected to the upper part of the first pulley assembly and the second pulley assembly, respectively.

[0035] This invention proposes a gravity energy storage device for non-fossil energy in barren mountains. The device includes an outer retaining wall 4, which is circular in structure. A supporting component is disposed within the outer retaining wall 4. The supporting component supports a vertical shaft component and stores a counterweight assembly 35. The vertical shaft component supports the energy storage mechanism and includes a first vertical shaft 21 and a second vertical shaft 22. The first vertical shaft 21 and the second vertical shaft 22 are connected to the lower part of the supporting component. The energy storage mechanism stores or generates energy and includes a first pulley assembly, a second pulley assembly, a drive component 33, a winch assembly, and a counterweight assembly 35. The counterweight assembly 35 can be a conventional counterweight block. The first pulley assembly is located in the first vertical shaft 21, and the second pulley assembly is located in the second vertical shaft 22. A counterweight assembly 35 is detachably connected to the lower part of either the first or second pulley assembly. The drive component 33 is connected to the winch assembly, which is connected to the upper parts of both the first and second pulley assemblies. Compared to existing technologies, this method uses a pyramid-shaped support structure with multiple motors in the middle. These motors drive a gravity block to move up and down for energy storage. However, since the multiple motors operate independently, they frequently run empty runs during energy storage or release. When centralized power generation is needed, after the motors lower the gravity block, the bridge box needs to be individually retracted to the top. Then, a gravity block is lowered for power generation. When centralized energy storage is needed, the motor drives the bridge box and gravity block to the top and removes the gravity block. Then, the bridge box needs to be lowered to the bottom separately, and then the gravity block needs to be reinstalled for energy storage, which increases equipment wear and energy consumption. In this technical solution, a first pulley assembly and a second pulley assembly are respectively set in two vertical shafts. A drive component 33 and a winch assembly are set between the first vertical shaft 21 and the second vertical shaft 22. The first pulley assembly and the second pulley assembly are connected to the winch assembly, and the drive component 33 is connected to the winch assembly. During energy storage, the counterweight assembly 35 is transported to the lower part of the first pulley assembly and suspended by a conveying component. Existing electric transport vehicles can be used. Then, the drive unit 33 is started, and the drive unit 33 rotates clockwise, driving the winch assembly to rotate. The first pulley group, driven by the winch assembly, pulls the counterweight assembly 35 upward to the set position. At the same time, the second pulley assembly moves downward to the bottom of the second vertical shaft 22. Then, a new counterweight assembly 35 is assembled and moves upward. A position sensor and a transmitter are respectively installed on the set position and the counterweight assembly 35. When the counterweight assembly 35 reaches the set position, the position sensor detects the position of the transmitter, and the drive unit 33 stops rotating. This not only enables continuous operation but also reduces energy consumption and equipment wear, thereby achieving the technical effect of reducing production costs.

[0036] The aforementioned outer retaining wall 4 is either circular or rectangular in structure, constructed of cast concrete. The circular structure utilizes the "arch effect" to distribute earth pressure, and the annular retaining wall has no stress concentration points, making it particularly stable in the Gobi Desert's wind and sand erosion environment. The supporting components, located within the outer retaining wall 4, support the vertical shaft components and store the counterweight assembly 35. The supporting components include a first retaining wall 11, a second retaining wall 12, and a supporting beam 13. The first and second retaining walls 11 and 12 are longitudinally positioned below ground level, and the two ends of the supporting beam 13 are fixedly connected to the first and second retaining walls 11 and 12. This design is crucial when constructing the energy storage device. In deserts and Gobi with deep groundwater levels, a circular pit 100 meters in diameter and 100 meters deep is dug. The edge of the pit is surrounded by a circular concrete retaining wall. The excavated Gobi is then backfilled around the retaining wall. When constructing in deserts or barren mountains, an air-supported membrane needs to be installed on the upper part of the supporting components to enclose the energy storage device and reduce the impact of wind and sand on the equipment. Alternatively, a color steel plate can be installed on the upper part of the supporting components, and solar panels can be installed on top of the color steel plate for power generation. The counterweight component 35 is stacked around the outer perimeter of the retaining wall and at the bottom of the pit. The support beam 13 can support the two longitudinally arranged retaining walls, dispersing the shear force of the retaining walls themselves, thereby improving the support performance of the supporting components. The function of the shaft component is to support the energy storage mechanism. The component includes a first shaft 21 and a second shaft 22. The first shaft 21 is connected to the lower part of the supporting component, and the second shaft 22 is also connected to the lower part of the supporting component. The first shaft 21 is longitudinally arranged at the lower part of the supporting component. The exterior of the first shaft 21 is constructed of poured concrete, or backfilled and compacted with soil to support it. The first shaft 21 is made of stainless steel or brick-concrete composite material. A support rod 23 is installed between the first shaft 21 and the second shaft 22 to support them. A first opening 211 is provided at the bottom of the first shaft 21 for the conveying component of the counterweight assembly 35 to enter. The first shaft 21 and the second shaft 22 have the same structure. Therefore, it will not be elaborated further; the function of the energy storage mechanism is to store energy or generate electricity. The energy storage mechanism includes a first pulley assembly, a second pulley assembly, a drive component 33, a winch assembly, and a counterweight assembly 35. The first pulley assembly is located in the first vertical shaft 21, and the second pulley assembly is located in the second vertical shaft 22. The counterweight assembly 35 is detachably connected to the lower part of the first pulley assembly or the second pulley assembly. The drive component 33 is connected to the winch assembly, and the winch assembly is connected to the upper part of both the first pulley assembly and the second pulley assembly. The first pulley assembly includes a first pulley component 311, a second pulley component 312, and a first wire rope 313. The first pulley component 311 is fixedly installed in the upper part of the first vertical shaft 21, and one end of the first wire rope 313 is connected to the winch assembly.The other end is connected sequentially to the first pulley component 311 and the second pulley component 312. The second pulley assembly includes a third pulley component 321, a fourth pulley component 322, and a second wire rope 323. The third pulley component 321 is fixedly installed on the upper part of the first vertical shaft 21. One end of the second wire rope 323 is connected to the winch assembly, and the other end is sequentially connected to the third pulley component 321 and the fourth pulley component 322. The drive component 33 adopts a generator-motor integrated machine, which can not only start the winch assembly to rotate with electrical energy, but also generate electricity. When the drive component 33 rotates clockwise, the winch assembly retracts the first wire rope 313, and causes the second pulley component 312 to drive the counterweight assembly 35 to move upward. At the same time, the fourth pulley component 322 moves downward to the first wire rope 323. At the bottom of the second vertical shaft 22, the counterweight assembly 35 is suspended on the fourth pulley assembly 322 via the conveying component 9. Then, the drive component 33 rotates in the opposite direction, causing the winch assembly to rotate in the opposite direction. The winch assembly pulls the fourth pulley assembly and the counterweight assembly 35 upwards. This process is repeated for energy storage. When power generation is needed, the second pulley assembly 312 is located below the first pulley assembly 311. The conveying component 9 suspends the counterweight assembly 35 on the second pulley assembly 312. Then, the conveying component 9 exits the first vertical shaft 21 and opens the air brake of the winch assembly. The counterweight assembly 35 falls down the first vertical shaft 21 to the bottom of the first vertical shaft 21 under the action of gravity. During the fall of the counterweight assembly 35, the first wire rope 313 pulls the winch assembly to rotate and drives the winch assembly to rotate. The drive component 33 generates electricity. Simultaneously, during the rotation of the winch assembly, the second wire rope 323 pulls the fourth pulley block upwards to the lower part of the third pulley component 321. Then, the conveying component 9 at the bottom of the first shaft 21 pulls out the counterweight component 35, and the conveying component 9 at the top of the second shaft 22 transports the new counterweight component 35 into the second shaft 22 and suspends it on the fourth pulley component 322, thereby achieving the technical effect of continuous power generation. Optionally, a car can be installed outside the second pulley component 312 and the fourth pulley component 322 to protect them. In this technical solution, by setting the first pulley assembly and the second pulley assembly in the two shafts respectively, the first shaft 21 and... A drive unit 33 and a winch assembly are installed between the second shafts 22. The first and second pulley assemblies are connected to the winch assembly, and the drive unit 33 is also connected to the winch assembly. During energy storage, the counterweight assembly 35 is transported to the lower part of the first pulley assembly via the conveyor 9 and suspended. Then, the drive unit 33 is activated, rotating clockwise and driving the winch assembly to rotate. Driven by the winch assembly, the first pulley assembly pulls the counterweight assembly 35 upwards to a set position. Simultaneously, the second pulley assembly moves downwards to the bottom of the second shaft 22. Then, a new counterweight assembly 35 is installed and moved upwards. This system not only enables continuous operation but also reduces energy consumption and equipment wear, thereby achieving the technical effect of reducing production costs.

[0037] Furthermore, the winch assembly includes a first winch 341, a second winch 342, an air supply component, and an air brake switch 344. The first winch 341 is connected to the first wire rope 313, and the second winch 342 is connected to the second wire rope 323. One end of the air brake switch 344 is connected to the air supply component, and the other end is connected to the first winch 341 and the second winch 342 respectively.In this embodiment, the winch assembly is further defined. The air supply component supplies air to the air brake switch 344. During energy storage, after the air supply component supplies air to the air brake switch 344 to 10 atmospheres, the conveying component 9 transports the counterweight assembly 35 to the bottom of the first vertical shaft 21 and lifts the counterweight assembly 35, suspending it on the first pulley component 311. Specifically, the air supply component includes an air tank 3431 and an air pump 3432. The air pump 3432 is connected to the air tank 3431, and the air tank 3431 is connected to the air brake switch 344. When the pressure inside the air tank 3431 is higher than 15 atmospheres, the pressure relief valve on the air tank 3431 releases pressure. When the pressure inside the air tank 3431 is lower than 10 atmospheres, the air pump 3432 starts supplying air to the air tank 3431. 31. Gas supply begins, and the drive unit 33 rotates clockwise. The first winch 341 retracts the first wire rope 313, causing the second pulley 312 to move the counterweight assembly 35 upwards. Simultaneously, the second winch 342 lowers the second wire rope 323, and the fourth pulley 322 moves downwards to the bottom of the second shaft 22. The counterweight assembly 35 is then suspended on the fourth pulley 322 via the conveying unit 9. The drive unit 33 then rotates in the opposite direction, causing the second winch 342 to rotate in the opposite direction as well. The second winch 342 pulls the fourth pulley assembly and the counterweight assembly 35 upwards. This process is repeated for energy storage. When power generation is required, the second pulley 312 is positioned below the first pulley 311, and the conveying unit 9 suspends the counterweight assembly 35 on the second pulley. On 312, the conveying component 9 opens out of the first vertical shaft 21, and the air brake switch 344 is activated. The counterweight assembly 35, under the influence of gravity, falls down along the first vertical shaft 21 to the bottom. During the descent of the counterweight assembly 35, the first wire rope 313 pulls the first winch 341 to rotate, which in turn drives the drive component 33 to generate electricity. Simultaneously, the first winch 341 rotates, causing the second wire rope 323 to pull the fourth pulley block upwards to the lower part of the third pulley component 321. Then, the conveying component 9 at the bottom of the first vertical shaft 21 pulls out the counterweight assembly 35. The conveying component 9 at the top of the second vertical shaft 22 transports the new counterweight assembly 35 into the second vertical shaft 22 and suspends it on the fourth pulley component 322, thereby driving the drive component 33 to rotate and... Optionally, for power generation, speed sensors can be installed on the wheel discs of the first winch 341 and the second winch 342. The speed sensors are located on the outer ring of the wheel discs. When the wheel discs of the first winch 341 and the second winch 342 stall, the speed sensors transmit a signal to the control system. The control system then controls the air brake switch 344 to cut off the air brake, causing the first winch 341 and the second winch 342 to stop rotating. At the same time, the control system sends a signal to the alarm, which then sounds an alarm. Specifically, a first brake strip 345 and a second brake strip 346 are respectively installed on the first winch 341 and the second winch 342. The braking force is generated through friction with the brake pads, thereby achieving deceleration or stopping of the first winch 341 and the second winch 342.

[0038] Furthermore, the energy storage mechanism also includes a reduction gear, which comprises a first gear 361, a second gear 362, and a third gear 363. The third gear 363 is connected to the drive component 33, the first gear 361 is connected to the first winch 341, and the second gear 362 is connected to the second winch 342. In this embodiment, the energy storage mechanism is further defined. The function of the reduction gear is to adjust the rotational speed and torque. The third gear 363 is installed at the output end of the drive component 33, the first gear 361 is installed at the output end of the first winch 341, and the second gear 362 is installed at the output end of the second winch 342. The third gear 363 meshes with the first gear 361 and the second gear 362, thereby achieving the technical effect of adjusting the rotational speed and torque of the drive component 33. Optionally, a reducer 37 is provided between the third gear 363 and the drive component 33. The function of the reducer 37 is also to adjust the rotational speed and torque, so that the reducer 37, the reduction gear, and the pulley assembly work simultaneously to achieve a multi-stage reduction effect.

[0039] Furthermore, the support component also includes a connector, which is disposed on the top of the first retaining wall 11 and the second retaining wall 12. The connector includes a cone 141 and a ring 142. The edge of the cone 141 is connected to the ring 142. The first retaining wall 11 and the second retaining wall 12 extend into the cone 141 and are connected to the inner side of the cone 141. The ring 142 has a first through hole, and the edge of the first through hole is fixedly connected to the side of the first retaining wall 11 and the second retaining wall 12. In this embodiment, the supporting components, connectors, first retaining wall 11 and second retaining wall 12 form an arrow-shaped concrete retaining wall. When constructing an energy storage device in the partition at the foot of the mountain, the cone 141 faces the direction of the mountain. The main reason is that the elevation difference of the mountain will cause the effect of gravity differentiation. Gravel in the Gobi Desert moves down the slope under the drive of gravity and forms landslides or debris flows. The arrow-shaped retaining wall blocks and diverts the gravel, protecting the energy storage device. A first through hole is provided in the middle of the ring 142. The outer surfaces of the first retaining wall 11 and second retaining wall 12 are fixedly connected to the inner surfaces of the first through hole. The edge of the cone 141 is fixedly connected to the outer edge of the ring 142, so that the connector can disperse the shear force of the first retaining wall 11 and second retaining wall 12 to both sides, thereby achieving the technical effect of improving the stability of the first retaining wall 11 and second retaining wall 12.

[0040] Furthermore, the supporting components also include steel cables 15 and ground anchors 16. One end of the steel cable 15 is connected to the first retaining wall 11 and the second retaining wall 12, and the other end is fixed in the rock stratum. In this embodiment, the supporting components are further defined, and there are multiple steel cables 15. One end of each steel cable 15 is fixedly connected to the outside of the first retaining wall 11, and the other end is fixed in the rock stratum or soil stratum by the ground anchor 16, thereby fixing the first retaining wall 11. The connection method between the second retaining wall 12 and the steel cables 15 is the same, and will not be described again.

[0041] Furthermore, a support platform 17 is provided, located on the side of the first retaining wall 11 and the second retaining wall 12 away from the support beam 13. The support platform 17 is positioned outside the first retaining wall 11 and the second retaining wall 12, and a counterweight assembly 35 for lifting to the top is placed on the support platform 17. Multiple support platforms 17 are provided, and they are horizontally positioned. Optionally, such as... Figure 3 As shown, a hoisting component has been added, which includes a mounting bracket and a gantry crane. The bracket is fixed to the inner side of the outer retaining wall 4, and the gantry crane 18 is mounted on the bracket. A bracket 19 is mounted on the outer retaining wall 4, and the gantry crane 18 is mounted on the bracket 19, which facilitates the gantry crane hoisting of the counterweight component 35. Optionally, the gantry crane 18 is set on the upper part of the bearing platform 17. The gantry crane 18 is used to move the counterweight component 35 to the conveying component 9, thereby facilitating the movement of the counterweight component 35. After the gantry crane 18 lifts the counterweight component 35 from the conveying component 9, it is also necessary to stack the counterweight component 35. Of course, the gantry crane 18 can also be set on the inner wall of the rock layer or concrete. When the gantry crane 18 is set on the ring body 142, an arched beam needs to be installed at the lower part of the ring body 142 to support the ring body 142 and improve the stability of the ring body 142.

[0042] Furthermore, the conveying components include a lifting platform and a roller assembly. The lifting platform is located at the lower part of the first shaft 21 and the second shaft 22, and is situated inside the first shaft 21 and the second shaft 22.
