Description

Technical Field

[0001] This utility model relates to the field of conveying equipment technology, and more specifically, to a load-bearing cable-type dual-drive bulk material conveying system and its gravity flow energy storage system. Background Technology

[0002] In recent years, significant progress has been made in the development of new energy sources; however, problems such as large fluctuations in grid connection and poor grid stability have become increasingly prominent. New energy storage, as a means of regulating power supply and demand, can effectively address these issues. Gravity energy storage, among other new energy storage technologies, is particularly suitable for large-scale grid energy storage and medium-to-long-term energy storage scenarios due to its advantages such as long storage time, no energy decay, long lifespan, high safety, and low maintenance costs. It is especially beneficial in areas with abundant wind and solar energy resources but unstable power output, effectively regulating power load, achieving energy balance and transfer, and improving the absorption capacity of renewable energy. However, gravity energy storage systems often suffer from intermittent charging / discharging issues because they rely on the lifting and lowering of large amounts of heavy objects to achieve potential energy conversion.

[0003] Therefore, the mechanism of bulk material transport has been applied to the field of gravity energy storage, giving rise to continuous charging / discharging bulk material transport gravity energy storage systems. However, existing bulk material transport gravity energy storage systems transport bulk materials by belt traction. The belt and idlers generate indentation resistance, and the material on the belt experiences squeezing resistance as it passes over the idlers, resulting in excessive operating resistance and low transport efficiency. Simultaneously, the belt bears significant tensile stress in the direction of travel, making it prone to longitudinal tearing and belt breakage, which is difficult to engineer to meet the efficiency requirements of gravity energy storage.

[0081] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0082] Example

[0083] This embodiment provides a load-bearing cable-type dual-drive bulk material conveying system and its gravity flow energy storage system, which can be used to store electrical energy, especially electrical energy generated by wind power and photovoltaic power generation technologies, and can also be used to generate continuous discharge.

[0084] See Figures 1-9 As shown, the load-bearing cable-type dual-drive bulk material conveying system includes a load-bearing structure 100, a traction structure 200, a conveying structure 300, a drive device 400, a first steering structure 600, and a second steering structure 700.

[0085] The conveying structure 300 includes a ring-shaped conveyor belt 310 and a plurality of transport vehicles 320; along the extension direction of the conveyor belt 310, the plurality of transport vehicles 320 are sequentially fixedly connected to the conveyor belt 310; optionally, along the extension direction of the conveyor belt 310, the plurality of transport vehicles 320 are evenly connected to the conveyor belt 310.

[0086] The load-bearing structure 100 includes two load-bearing tracks 110 and two load-bearing cables 120; the two load-bearing cables 120 are arranged in parallel, and the two load-bearing tracks 110 are respectively connected to the two ends of the two load-bearing cables 120, so that the two load-bearing tracks 110 and the two load-bearing cables 120 form a ring-shaped load-bearing cable rail; the load-bearing cable rail is configured to carry all the transport vehicles 320, and all the transport vehicles 320 can move cyclically along the load-bearing cable rail; that is, the load-bearing cable rail is a ring formed by connecting the load-bearing tracks 110, the load-bearing cables 120 end to end.

[0087] The traction structure 200 includes a traction cable 210 that tractions all the carrier vehicles 320; the traction cable 210 is looped. The shape of the supporting cable rail corresponds to the shape of the traction cable 210.

[0088] Both the first steering structure 600 and the second steering structure 700 are steering structures, each including a drum 610 and a steering wheel 620. The conveyor belt 310 circulates between the drums 610 of the first steering structure 600 and the second steering structure 700, and the traction cable 210 circulates between the steering wheels 620 of the first steering structure 600 and the second steering structure 700. This cable-driven dual-drive bulk material conveying system can be used on hillsides or flat terrain; for example, the first steering structure 600 is located at a low altitude, and the second steering structure 700 is located at a higher altitude relative to the low altitude.

[0089] The drive unit 400 is connected to the first steering structure 600 and / or the second steering structure 700 to drive the traction cable 210 and the conveyor belt 310 to rotate synchronously in a first direction. That is, it can drive the first steering structure 600 and the second steering structure 700 to rotate around the first direction, thereby driving the transport vehicle 320 to move along the load-bearing cable track. Simultaneously, the transport vehicle 320 and the conveyor belt 310 move synchronously. Specifically, the drive unit 400 is connected to either the first steering structure 600, the second steering structure 700, or both.

[0090] Optionally, both the first steering structure 600 and the second steering structure 700 are connected to the bracket.

[0091] See Figures 1-3As shown, in the optional embodiment, the axial direction of the first steering structure 600 and the axial direction of the second steering structure 700 are both parallel to the horizontal direction; this is equivalent to the first steering structure 600 and the second steering structure 700 being placed vertically. Compared to horizontal placement, this requires less ground space, has simpler terrain requirements, and is easier to install on more sloping terrains. Simultaneously, the smaller installation space facilitates the simultaneous installation of multiple systems, which can increase system capacity and enable high-power energy storage / discharge.

[0092] Optionally, both the steering wheel 620 of the first steering structure 600 and the steering wheel 620 of the second steering structure 700 are provided with traction wheel grooves that cooperate with the traction cable 210. The traction wheel grooves increase the friction between the traction cable 210 and the first steering structure 600 and the second steering structure 700, and also prevent the traction cable 210 from disengaging from the steering wheel 620 of the first steering structure 600 and the steering wheel 620 of the second steering structure 700.

[0093] The dual-drive bulk material conveying system described in this embodiment uses a drum 610 to drive the conveyor belt 310 and a steering wheel 620 to drive the traction cable 210. This dual-drive system transfers the bulk material loaded on the conveyor belt 310, reducing running resistance and effectively increasing the carrying capacity of the conveyor belt 310. It also reduces the performance requirements of the conveyor belt 310, effectively lowering the probability of longitudinal tearing and belt breakage. The load-bearing structure 100 supports all the transport vehicles 320, which in turn carry the bulk material loaded on the conveyor belt 310. This effectively reduces or avoids the additional tension on the conveyor belt 310 due to the weight of the bulk material, greatly improving the stability and carrying capacity of the dual-drive bulk material conveying system.

[0094] In the load-bearing cable-type dual-drive bulk material conveying system described in this embodiment, since the traction cable 210 bears part of the traction force, the conveyor belt 310 only bears part of the tensile stress along the walking direction. This can reduce the demand for the traction force of the conveyor belt 310 to a certain extent, allowing the use of a more economical conveyor belt 310 and significantly improving the service life of the conveyor belt 310.

[0095] See Figures 1-3 As shown, in the optional embodiment, the load-bearing rails are arranged in pairs, and the conveyor belt 310 is located between the paired load-bearing rails; that is, the ring structure formed by the two load-bearing rails 110 and the two load-bearing cables 120 is arranged in pairs. By arranging the load-bearing rails in pairs, the carrier vehicle 320 is better supported, thereby improving the stability of the carrier vehicle 320 during operation to a certain extent, and thus improving the stability of the conveying structure 300 during operation.

[0096] Optionally, the traction cables 210 are arranged in pairs, and the conveyor belt 310 is located between the pairs of traction cables 210. By arranging the traction cables 210 in pairs, the carrier 320 is better pulled, thereby improving the stability of the carrier 320 during operation and increasing the traction force on the carrier 320, which in turn improves the stability of the conveyor structure 300 during operation and increases the traction force on the carrier 320.

[0097] See Figures 7-9 As shown, in the optional embodiment, the carrier vehicle 320 includes a load-bearing beam 321, a traveling wheel 322, and a rope connecting device 323; the load-bearing beam 321 is fixedly connected to the conveyor belt 310; optionally, the load-bearing beam 321 is fixedly connected inside the conveyor belt 310, or the load-bearing beam 321 is fixedly connected to the side of the conveyor belt 310 away from the steering structure, for example, the load-bearing beam 321 is fixedly connected above the conveyor belt 310.

[0098] Optionally, at least one pair of traveling wheels 322 are pivotally connected to both sides of the supporting beam 321, and the traveling wheels 322 are configured to travel on the supporting cable rails; optionally, the number of traveling wheels 322 is the same as the number of supporting cable rails. By pairing the traveling wheels 322 and the supporting cable rails, the transport vehicle 320 is better supported, thereby improving the stability of the transport vehicle 320 during operation, and thus enhancing the stability of the conveying structure 300 during operation. Specifically, the traveling wheels 322 travel on the supporting cable rails, that is, on the supporting rails 110 and the supporting cable 120.

[0099] Optionally, at least one pair of rope connecting devices 323 are rotatably connected to both sides of the bearing beam 321; the rope connecting device 323 is fixedly connected to the traction cable 210, and the rotation axis of the rope connecting device 323 forms an angle with the extension direction of the traction cable 210. Optionally, the rotation axis of the rope connecting device 323 is perpendicular to the extension direction of the traction cable 210. The rope connecting device 323 is rotatably connected to the bearing beam 321 to facilitate the movement of the transport vehicle 320 along the annular traction cable 210. By using paired rope connecting devices 323 to connect the bearing beam 321, the stability of the transport vehicle 320 during movement is improved. In this embodiment, the number of pairs of rope connecting devices 323 can be selected based on factors such as the material and connection strength of the rope connecting devices 323.

[0100] In this embodiment, the rope connection device 323 can take various forms, such as a claw type or a locking buckle. See also Figure 9As shown, in the optional embodiment, the rope connection device 323 includes a rope connection body 3231 and a gripper 3232. The gripper 3232 is fixedly connected to the end of the rope connection body 3231, and the jaws 3233 of the gripper 3232 face the center line of the traction cable 210, so that the gripper 3232 can move with the traction cable 210. When the carrier vehicle 320 turns to the first steering structure 600 or the second steering structure 700, the rotation interference of the rope connection device 323 at the steering wheel 620 of the first steering structure 600 or the steering wheel 620 of the second steering structure 700 is reduced, so that the rope connection device 323 can pass smoothly through the steering wheel 620 of the first steering structure 600 or the steering wheel 620 of the second steering structure 700.

[0101] The gripper 3232 is fixedly connected to the traction cable 210. A transport bearing 3234 is connected between the rope connection body 3231 and the load-bearing beam 321. The transport bearing 3234 reduces the friction between the rope connection body 3231 and the load-bearing beam 321, which helps the transport vehicle 320 to turn at the first steering structure 600 or the second steering structure 700.

By providing traction guide devices 220 in both the upper redirecting traction section 216 and the lower redirecting traction section 218, the contact angle and contact area between the traction cable 210 and the traction guide device 220 are increased, which is beneficial for the turning of the upper redirecting traction section 216 and the lower redirecting traction section 218, thereby helping to reduce the height of the track support frame 130, increasing overall stability and reducing investment.

[0125] See Figures 1-3 As shown, in the optional embodiment, the load-bearing cable rail includes an upward load-bearing section and a downward load-bearing section connected end to end; the upward load-bearing section and the downward load-bearing section are connected end to end to form a ring structure.

[0134] This embodiment also provides a load-bearing cable-type dual-drive bulk material conveying gravity flow energy storage system, including the load-bearing cable-type dual-drive bulk material conveying system described in any of the above embodiments, and further including a power generation device 500.

[0135] The first steering structure 600 is located at a low altitude, while the second steering structure 700 is located at a high altitude relative to the low altitude.

[0136] When the conveyor belt 310 rotates in the first direction, that is, when the drive device 400 simultaneously drives the traction cable 210 and the conveyor belt 310 to rotate synchronously in the first direction, the conveyor belt 310 can drive the loaded bulk materials to be transported to a high altitude, thereby converting electrical energy into gravitational potential energy for storage.

[0137] The power generation device 500 is connected to the first steering structure 600 and / or the second steering structure 700. Under the influence of gravity, the conveyor belt 310 loaded with bulk material drives the conveyor belt 310 and the transport vehicle 320 to move along a second direction, continuously transporting the bulk material to a lower altitude and forming a continuous gravity flow. Simultaneously, it drives the first steering structure 600 and the second steering structure 700 to rotate along the second direction, thereby driving the power generation device 500 to generate electricity, converting the continuous gravity flow into a continuous energy flow, thus achieving continuous discharge. The first direction is opposite to the second direction. For example, if the first direction is clockwise, the second direction is counterclockwise, and vice versa. When the transport vehicle 320 moves along the second direction, for example, along the carrying cable track and in the second direction...

[0138] The load-bearing cable-type dual-drive bulk material conveying gravity flow energy storage system described in this embodiment uses a drum 610 to drive the conveyor belt 310 and a steering wheel 620 to drive the traction cable 210. This dual-drive method jointly transfers the bulk material loaded on the conveyor belt 310, which can reduce operating resistance to a certain extent, effectively improve the carrying capacity of the conveyor belt 310, and also reduce the performance requirements of the conveyor belt 310 to a certain extent, effectively reducing the probability of longitudinal tearing, belt breakage, and other failures. The load-bearing structure 100 supports all the transport vehicles 320, effectively reducing or avoiding the additional tension on the conveyor belt 310 due to overcoming the weight of the bulk material, greatly improving the system's stability and carrying capacity. The power generation device 500 can convert the continuous gravity flow into a continuous energy flow, thereby achieving continuous discharge.

[0139] The load-bearing cable-type dual-drive bulk material conveying gravity flow energy storage system provided in this embodiment includes the aforementioned load-bearing cable-type dual-drive bulk material conveying system. The technical features of the disclosed load-bearing cable-type dual-drive bulk material conveying system are also applicable to this load-bearing cable-type dual-drive bulk material conveying gravity flow energy storage system. The technical features of the previously disclosed load-bearing cable-type dual-drive bulk material conveying system will not be repeated here. The load-bearing cable-type dual-drive bulk material conveying gravity flow energy storage system in this embodiment possesses the advantages of the aforementioned load-bearing cable-type dual-drive bulk material conveying system. The advantages of the previously disclosed load-bearing cable-type dual-drive bulk material conveying system will not be repeated here.

[0140] Optionally, the steering structure also includes a coupling; in the same steering structure, the drum 610 and the steering wheel 620 are coaxially arranged and both are connected to the coupling. That is, the drum 610 and the steering wheel 620 of the first steering structure 600 are coaxially arranged, and the drum 610 and the steering wheel 620 of the second steering structure 700 are coaxially arranged.

[0141] Optionally, the drive unit 400 is connected to a coupling. In this embodiment, the drive unit 400 can be located at a low altitude or a high altitude, or both at a low altitude and a high altitude. Being located at a high altitude reduces the load during energy storage, while being located at a low altitude facilitates the installation of the drive unit 400.

[0142] Optionally, the power generation device 500 is connected to a coupling. In this embodiment, the power generation device 500 can be located at a low altitude or a high altitude, or the power generation device 500 connected to the coupling can be located at both low and high altitudes. Located at a high altitude, the load during the energy storage process can be reduced, while located at a low altitude, the installation of the power generation device 500 is convenient.

[0143] In this embodiment, the drive device 400 and the generator 500 can be integrated or separate. Optionally, the drive device 400 and the generator 500 can be electric generators, or the drive device 400 and the generator 500 can be independent of each other. Here, an electric generator (English name: Motor-Generator) in this embodiment refers to a device that can both convert electrical energy into gravitational potential energy as a motor and convert gravitational potential energy into electrical energy as a generator, possessing bidirectional energy conversion capabilities.

[0144] Currently, gravity energy storage systems rely on the lifting and lowering of heavy objects to achieve potential energy conversion, resulting in intermittent charging / discharging issues in most cases. The load-bearing cable-type dual-drive bulk material conveying system and its gravity flow energy storage system described in this embodiment represent a novel mechanical gravity energy storage technology. It aims to utilize bulk energy storage bodies to provide a continuous gravity flow, thereby achieving a continuous energy flow and solving the problems of intermittency, site selection difficulties, and high investment costs associated with existing gravity energy storage systems.

[0145] The load-bearing cable-type dual-drive bulk material conveying system and its gravity flow energy storage system described in this embodiment have the following advantages:

[0146] 1. Apply the conveying principle of bulk material transportation to the field of gravity energy storage to achieve continuous gravity flow energy storage.

[0147] 2. Traditional belt conveyors are driven by a belt. This solution uses a drum 610 to drive the conveyor belt 310 and a steering wheel 620 to drive the traction cable 210, using a dual-drive system to transfer the bulk material loaded on the conveyor belt 310, effectively improving the carrying capacity of the conveyor belt 310. The traction cable 210 and the conveyor belt 310 jointly drive and pull the bulk material loaded on the conveyor belt 310. The load-bearing structure 100 supports all the transport vehicles 320, which in turn carry the bulk material loaded on the conveyor belt 310. This effectively reduces or avoids the load-bearing capacity of the conveyor belt 310 and the traction cable 210, greatly improving the stability and carrying capacity of the load-bearing cable-type dual-drive bulk material conveying system. Through the load-bearing structure 100 and the traction cable 210, the conveyor belt 310 only bears part of the tensile stress along the traveling direction, thereby reducing the performance requirements of the conveyor belt 310 and allowing the use of a more economical conveyor belt 310, which can significantly extend its service life. At the same time, the conveyor belt 310, which bears part of the traction force, also reduces the probability of longitudinal tearing, belt breakage, and other failures.

[0148] 3. Traditional belt conveyors use idlers to support the upper and lower branch belts, and the idlers rotate as the belts run. In this embodiment, a carrier 320 supports the conveyor belt 310. The carrier 320 and the conveyor belt 310 run together via a traction cable, avoiding the crushing resistance between the conveyor belt 310 and the idlers, as well as the squeezing resistance of materials passing over the idlers. This significantly reduces running resistance and improves conveying efficiency.

[0149] 4. The carrier 320 is used instead of the idler roller. The carrier 320 is connected to the conveyor belt 310 as a whole. When the carrier 320 runs along the bearing structure 100, the rolling resistance between the wheels of the carrier 320 and the bearing structure 100 is much smaller than the rolling resistance of the idler roller.

[0150] 5. If the idler rollers are not installed correctly, they will twist the conveyor belt 310, which can easily cause the conveyor belt 310 to run off-center. In this embodiment, the carrier 320 is fixed to the conveyor belt 310, so there is no problem with the conveyor belt running off-center.

[0151] 6. Idler rollers are arranged along the entire conveyor line, and their inspection and maintenance require a significant amount of manpower, resources, and time. This embodiment allows for fixed-point maintenance of the transport vehicle 320 at specific locations.

[0152] 7. To work with the traction cable, an integrated steering wheel 620 and drum 610 were innovatively designed. The steering wheel 620 and drum 610 are mounted on the same shaft. The diameters of the steering wheel 620 and drum 610 are matched with the corresponding wire rope diameters and conveyor belt 310 thicknesses. In addition, the load-bearing beam 321 of the carrier vehicle 320 was innovatively pre-embedded in the conveyor belt 310 during the production process, ensuring the stability of the load-bearing beam 321.

[0153] 8. To facilitate wider system application and reduce system space occupation, a traction guide device 220 was designed. On one hand, it elevates the lower redirecting traction section 218 to prevent it from contacting the ground; on the other hand, the upper redirecting traction section 216 shortens the distance between the upper inclined traction section 213 and the lower inclined traction section 217. Simultaneously, the traction guide device 220 increases the contact angle / contact area between the traction cable and the steering wheel 620, enhancing friction and thus increasing the system's carrying capacity and charging / discharging power.

[0154] 9. The 120 load-bearing cable replaces the track installed on the ground, which can cross ravine terrain, greatly reducing the investment in civil engineering and steel structure, while avoiding large-scale ground occupation, protecting vegetation, and practicing the concept of green mountains and clear waters.

[0155] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
