Description

Technical Field

[0001] The utility model relates to the technical field of conveying equipment, and in particular to a track-type double-drive bulk material conveying system and a gravity flow energy storage system thereof. Background Art

[0002] In recent years, the development of new energy has made remarkable achievements; however, problems such as large fluctuations in the grid connection of new energy and poor grid stability have become increasingly prominent. As a means of regulating electricity supply and demand, new energy storage can effectively solve the above-mentioned problems of new energy. Gravity energy storage, a new type of energy storage, is more suitable for large-scale grid energy storage and medium- and long-term energy storage scenarios due to its advantages such as long storage time, no attenuation, long life, high safety, and low maintenance cost. It is especially suitable for large-scale grid energy storage and medium- and long-term energy storage scenarios, especially in areas with abundant wind and solar energy resources but unstable power output. It can effectively regulate power loads, achieve energy balance and transfer, and enhance the ability to absorb renewable energy. Gravity energy storage systems rely on the lifting and lowering of a large number of heavy objects to achieve potential energy conversion, and most of them have intermittent charging / discharging problems.

[0003] Therefore, the application of bulk material transport mechanisms to gravity energy storage has led to the development of bulk material conveying gravity energy storage systems that achieve continuous charging and discharging. However, existing bulk material conveying gravity energy storage systems use belt traction to transport bulk materials. This creates compression resistance between the belt and rollers, and extrusion resistance as the material on the belt passes over the rollers. This results in excessive operating resistance and low transport efficiency. Furthermore, the belt is subject to significant tensile stress in the direction of travel, making it prone to longitudinal tearing and breakage, making it difficult to engineer within the efficiency requirements of gravity energy storage.

[0072] The following embodiments of the present invention are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.

[0073] Example

[0074] This embodiment provides a track-type dual-drive bulk material conveying system and a gravity flow energy storage system thereof, which can be used to store electrical energy, especially electrical energy generated by power generation technologies such as wind power and photovoltaic power generation, and can also be used to generate continuous discharge.

[0075] See also Figures 1-8 As shown, the track-type dual-drive bulk material conveying system includes a bearing structure 100 , a traction structure 200 , a conveying structure 300 , a driving device 400 , a first steering structure 600 and a second steering structure 700 .

[0076] The conveying structure 300 includes a ring-shaped conveyor belt 310 and multiple carriers 320; along the extension direction of the conveyor belt 310, the multiple carriers 320 are fixedly connected to the conveyor belt 310 in sequence; optionally, along the extension direction of the conveyor belt 310, the multiple carriers 320 are evenly connected to the conveyor belt 310.

[0077] The supporting structure 100 includes a supporting track 110 that supports all the vehicles 320; the supporting track 110 is annular. The traction structure 200 includes a traction rope 210 that pulls all the vehicles 320; the traction rope 210 is annular. The shape of the supporting track 110 corresponds to the shape of the traction rope 210.

[0078] The first steering structure 600 and the second steering structure 700 are both steering structures, each comprising a drum 610 and a steering wheel 620. The conveyor belt 310 circulates between the drum 610 of the first steering structure 600 and the drum 610 of the second steering structure 700, and the traction cable 210 circulates between the steering wheel 620 of the first steering structure 600 and the steering wheel 620 of the second steering structure 700. The track-type dual-drive bulk material conveying system can be used on both hillsides and flat surfaces; for example, the first steering structure 600 can be located at a low altitude, while the second steering structure 700 can be located at a higher altitude opposite the low altitude.

[0079] The driving device 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 the first direction, that is, to drive the first steering structure 600 and the second steering structure 700 to rotate about the first direction, thereby driving the transport vehicle 320 to move along the support rail 110, and simultaneously, the transport vehicle 320 and the conveyor belt 310 move synchronously. The driving device 400 is connected to the first steering structure 600 and / or the second steering structure 700, specifically, the driving device 400 is connected to the first steering structure 600, or the driving device 400 is connected to the second steering structure 700, or the driving device 400 is connected to the first steering structure 600 and the second steering structure 700.

[0080] Optionally, the first steering structure 600 and the second steering structure 700 are both connected to the bracket.

[0081] See also Figure 1-Figure 3 As shown, in an alternative embodiment of this embodiment, the axial directions of the first steering structure 600 and the second steering structure 700 are both parallel to the horizontal direction. This is equivalent to placing the first steering structure 600 and the second steering structure 700 vertically. Compared to horizontal placement, this requires less ground space and has simpler terrain requirements, making it easier to install on more sloping sites. Furthermore, the smaller installation space facilitates the simultaneous installation of multiple systems, which can improve system capacity and increase the amount of high-power storage and discharge of electrical energy.

[0082] Optionally, the steering wheel 620 of the first steering structure 600 and the steering wheel 620 of the second steering structure 700 are both provided with a traction wheel groove that cooperates with the traction rope 210. The traction wheel groove can increase the friction between the traction rope 210 and the first steering structure 600 and the second steering structure 700, and can also prevent the traction rope 210 from separating from the steering wheel 620 of the first steering structure 600 and the steering wheel 620 of the second steering structure 700.

[0083] The track-mounted dual-drive bulk material conveying system described in this embodiment utilizes a reel 610 to drive the conveyor belt 310 and a steering wheel 620 to drive the traction cable 210. This dual-drive system jointly transports the bulk material loaded on the conveyor belt 310. This reduces operational resistance to a certain extent, effectively improving the carrying capacity of the conveyor belt 310 and reducing the performance requirements of the conveyor belt 310 to a certain extent, effectively reducing the probability of failures such as longitudinal tearing and belt breakage of the conveyor belt 310. The support structure 100 supports all the carriers 320, which in turn carry the bulk material loaded on the conveyor belt 310. This effectively reduces or eliminates the additional tension on the conveyor belt 310 caused by factors such as the weight of the bulk material, significantly improving the stability and carrying capacity of the track-mounted dual-drive bulk material conveying system.

[0084] In the rail-type dual-drive bulk material conveying system described in this embodiment, since the traction rope 210 bears part of the traction force, the conveyor belt 310 only bears part of the tensile stress along the traveling direction, which can reduce the demand for the conveyor belt 310 to bear the traction force to a certain extent, and can use a more economical conveyor belt 310, and can also greatly increase the service life of the conveyor belt 310.

[0085] See also Figure 1-Figure 3 As shown, in the optional scheme of this embodiment, the carrying rails 110 are arranged in pairs, and the conveyor belt 310 is located between the carrying rails 110 arranged in pairs; by arranging the carrying rails 110 in pairs, the carrier 320 can be better carried, so as to improve the stability of the carrier 320 during operation to a certain extent, thereby improving the stability of the conveying structure 300 during operation.

[0086] Optionally, the traction cables 210 are arranged in pairs, and the conveyor belt 310 is located between the traction cables 210 arranged in pairs; by arranging the traction cables 210 in pairs, the carrier 320 can be better pulled, so as to improve the stability of the carrier 320 during operation and the traction force on the carrier 320 to a certain extent, thereby improving the stability of the conveying structure 300 during operation and improving the traction force on the carrier 320.

[0087] See also Figure 6-Figure 8As shown, in an optional scheme of this embodiment, the carrier 320 includes a load-bearing beam 321, walking wheels 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 to the inside of 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.

[0088] Optionally, at least one pair of running wheels 322 is pivotally connected to either side of the load beam 321. The running wheels 322 are configured to run on the load rails 110. Optionally, the number of running wheels 322 matches the number of load rails 110. The running wheels 322 and the load rails 110 are arranged in pairs to better support the transport vehicle 320, thereby improving the stability of the transport vehicle 320 during operation and, in turn, the stability of the conveying structure 300 during operation.

[0089] Optionally, at least one pair of rope connection devices 323 are rotatably connected to either side of the load beam 321. The rope connection devices 323 are fixedly connected to the traction cable 210, with the rotation axis of the rope connection devices 323 forming an angle with the extension direction of the traction cable 210. Optionally, the rotation axis of the rope connection devices 323 is perpendicular to the extension direction of the traction cable 210. The rope connection devices 323 are rotatably connected to the load beam 321, allowing the transport vehicle 320 to travel along the endless traction cable 210. Using paired rope connection devices 323 to connect the load beam 321 improves the stability of the transport vehicle 320 during travel. In this embodiment, the number of pairs of rope connection devices 323 can be selected based on factors such as the material of the rope connection devices 323 and the connection strength.

[0090] In this embodiment, the rope connection device 323 can be in various forms, such as a claw type, a lock buckle, etc. Figure 8 As shown, in an optional scheme of this embodiment, the rope connecting device 323 includes a rope connecting body 3231 and a claw 3232; the claw 3232 is fixedly connected to the end of the rope connecting body 3231, and the jaw 3233 of the claw 3232 faces the center line of the traction rope 210, so that the claw 3232 can move with the traction rope 210. When the carrier 320 rotates to the first steering structure 600 or the second steering structure 700, the rotation interference of the rope connecting 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 connecting device 323 can smoothly pass through the steering wheel 620 of the first steering structure 600 or the steering wheel 620 of the second steering structure 700.

[0091] The claw 3232 is fixedly connected to the traction rope 210. A carrier bearing 3234 is connected between the rope connection body 3231 and the load beam 321. The carrier bearing 3234 reduces friction between the rope connection body 3231 and the load beam 321, facilitating the rotation of the carrier 320 at the first steering structure 600 or the second steering structure 700.

[0092] Optionally, the carrier bearing 3234 is a sliding bearing. The sliding bearing has a high load-bearing capacity, which provides a guarantee for the track-type dual-drive bulk material conveying system to continuously convey bulk materials.

[0093] Optionally, the traveling wheel 322 is a roller bearing; the roller bearing can withstand a larger radial load, which is beneficial for carrying the carrier 320 and further beneficial for carrying the bulk material on the conveyor belt 310.

[0094] Optionally, the support rail 110 has a wheel groove that cooperates with the running wheel 322; along the radial direction of the running wheel 322, the support rail 110 has a corresponding groove bottom and groove top, the groove bottom and groove top forming a wheel groove, the wheel groove extending along the extension direction of the support rail 110, the running wheel 322 abuts against the groove bottom and / or groove top; when the running wheel 322 rolls, the running wheel 322 abuts against the groove bottom and / or groove top. By the running wheel 322 rolling in the wheel groove of the support rail 110, the running wheel 322 can be realized to achieve circular motion along the annular support rail 110, that is, the carrier 320 can be realized to achieve circular motion along the annular support rail 110.

[0095] Optionally, the load-bearing rail 110 is a C-shaped steel, a U-shaped steel, an I-shaped steel, or other profiles with a wheel groove structure.

[0096] See also Figures 1-8 As shown, in an optional solution of this embodiment, the conveyor belt 310 includes a belt body 311 and sidewalls 312 disposed on both sides of the belt body 311. The sidewalls 312 are corrugated or zigzag along the extension direction of the conveyor belt 310. The sidewalls 312 improve the carrying capacity of the conveyor belt 310 and effectively prevent bulk materials from slipping. The corrugated or zigzag shape of the sidewalls 312 enables the conveyor belt 310 to be steered on a steering structure, for example, on the reel 610 of the first steering structure 600 and the reel 610 of the second steering structure 700.

[0098] Optionally, the conveyor belt 310 further includes a plurality of baffles 313, which are sequentially spaced between the two sidewalls 312 along the conveyor belt 310's extension direction. The sidewalls 312 and baffles 313 enhance the conveyor belt 310's carrying capacity and effectively prevent bulk materials from slipping. The height of the sidewalls 312, the spacing between the baffles 313, and the width of the belt body 311 can be customized as needed. The bulk materials are raised or lowered by the traction cable 210, driving the carrier 320 and the conveyor belt 310 on the carrier 320.

[0099] Optionally, the belt body 311, the sidewalls 312, the partitions 313, and the carrier 320 form an integrated structure; for example, the belt body 311, the sidewalls 312, the partitions 313, and the load beam 321 form an integrated structure. For example, based on a standard corrugated sidewall belt (i.e., the conveyor belt 310), the load beam 321 for the carrier 320 is embedded within the base belt (i.e., the belt body 311), so that the belt body 311 and the carrier 320 form an integrated structure. Optionally, the belt body 311 has a smooth surface on one side, and the sidewalls 312 and the partitions 313 are connected to the other side. The other side of the belt body 311 may also be connected to the load beam 321, or the load beam 321 may be located within the belt body 311. The smooth surface of the belt body 311 ensures that the conveyor belt 310 can pass through the reel 610 without obstruction.

By providing both the upper redirecting traction section 216 and the lower redirecting traction section 218 with the traction guide device 220, the contact angle and contact area between the traction rope 210 and the traction guide device 220 are increased, which facilitates the steering of the upper redirecting traction section 216 and the lower redirecting traction section 218, thereby facilitating the reduction of the height of the track support frame 130, increasing overall stability, and reducing investment.

[0112] See also Figure 1-Figure 3 As shown, in an optional solution of this embodiment, the carrying track 110 includes an upward carrying portion and a downward carrying portion connected end to end; the upward carrying portion and the downward carrying portion are connected end to end to form a ring structure.

[0113] The shape of the upward bearing portion corresponds to the shape of the upward traction rope portion, that is, the upward bearing portion includes a lower steering wheel bearing section 111, a lower horizontal bearing section 112, an upper inclined bearing section 113 and an upper horizontal bearing section 114 connected in sequence; the shape of the downward bearing portion corresponds to the shape of the downward traction rope portion, that is, the downward bearing portion includes an upper steering wheel bearing section 115, an upper redirecting bearing section 116, a lower inclined bearing section 117 and a lower redirecting bearing section 118 connected in sequence.

[0116] See also Figure 5 As shown, in an optional solution of this embodiment, the driving device 400 is connected to the reel 610 and the steering wheel 620 of the same steering structure; so that the driving device 400 drives the reel 610 and the steering wheel 620 of the same steering structure to rotate.

[0117] The steering structure also includes a coupling; in the same steering structure, the reel 610 and the steering wheel 620 are coaxially arranged and both are connected to the coupling.

[0118] The traction cable 210 is connected to a tensioning device. The tensioning device may include one or more of a weight-type structure, a hydraulic structure, and a screw-type structure. The tensioning device may also adopt other structures. The tensioning device increases the preload force of the traction cable 210, thereby facilitating the normal operation of the traction cable 210.

[0119] See also Figures 1-8 As shown, in the optional scheme of this embodiment, the rail-type dual-drive bulk material conveying system also includes transfer equipment and a storage yard for storing bulk materials; transfer equipment and storage yards are provided at both low-altitude and high-altitude locations; the transfer equipment is configured to transport bulk materials back and forth between the conveyor belt 310 and the storage yard to achieve charging, energy storage and discharge.

[0120] This embodiment further provides a track-type dual-drive bulk material conveying gravity flow energy storage system, comprising the track-type dual-drive bulk material conveying system described in any of the above embodiments, and further comprising a power generation device 500 .

[0121] The first steering structure 600 is located at a low altitude position, and the second steering structure 700 is located at a high altitude position opposite to the low altitude position.

[0122] When the conveyor belt 310 rotates in the first direction, that is, when the driving device 400 drives the traction rope 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 position in succession, thereby converting electrical energy into gravitational potential energy storage.

[0123] The power generation device 500 is connected to the first steering structure 600 and / or the second steering structure 700. Under the action of gravity, the conveyor belt 310 loaded with bulk material drives the conveyor belt 310 and the carrier 320 to move in the second direction, transporting the bulk material to a lower elevation and forming a continuous gravity flow. Simultaneously, the first steering structure 600 and the second steering structure 700 are driven to operate in the second direction to drive the power generation device 500 to generate electricity, thereby converting the continuous gravity flow into a continuous energy flow, thereby 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 carrier 320 moves in the second direction, for example, the carrier 320 moves along the support rail 110 and in the second direction.

[0124] The rail-type dual-drive bulk material conveying gravity flow energy storage system described in this embodiment uses a reel 610 to drive the conveyor belt 310 and a steering wheel 620 to drive the traction cable 210. The dual-drive method can jointly transport the bulk material loaded on the conveyor belt 310. This can reduce the running 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, which can effectively reduce the probability of failures such as longitudinal tearing and belt breakage of the conveyor belt 310. By supporting all the carriers 320 through the support structure 100, the additional tension generated by the conveyor belt 310 due to overcoming factors such as the weight of the bulk material is effectively reduced or avoided, greatly improving the stability and carrying capacity of the system. The power generation device 500 can convert the continuous gravity flow into a continuous energy flow, thereby achieving continuous discharge.

The technical features of the above-mentioned track-type dual-drive bulk material conveying system are also applicable to this track-type dual-drive bulk material conveying gravity flow energy storage system. The technical features of the above-mentioned track-type dual-drive bulk material conveying system are not repeated here. The track-type dual-drive bulk material conveying gravity flow energy storage system described in this embodiment has the advantages of the above-mentioned track-type dual-drive bulk material conveying system. The advantages of the above-mentioned track-type dual-drive bulk material conveying system are not repeated here.

[0126] Optionally, the steering structure further includes a coupling; in the same steering structure, the reel 610 and the steering wheel 620 are coaxially arranged and both are connected to the coupling. That is, the reel 610 and the steering wheel 620 of the first steering structure 600 are coaxially arranged, and the reel 610 and the steering wheel 620 of the second steering structure 700 are coaxially arranged.

[0127] Optionally, the drive device 400 is connected to a coupling. In this embodiment, the drive device 400 can be installed at a low altitude or a high altitude, or the drive device 400 can be installed at both the low altitude and high altitude positions to drive the coupling. The high altitude position reduces the load during energy storage, while the low altitude position facilitates installation of the drive device 400.

[0128] Optionally, the generator 500 is connected to a coupling. In this embodiment, the generator 500 can be installed at a low altitude or a high altitude, or at both low and high altitudes. The high altitude location reduces the load during energy storage, while the low altitude location facilitates installation of the generator 500.

[0129] 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 are motor-generators, or the drive device 400 and the generator 500 are independent of each other. In this embodiment, a motor-generator (also known as a motor-generator) refers to a device that can operate both as a motor, converting electrical energy into gravitational potential energy, and as a generator, converting gravitational potential energy into electrical energy, thus providing bidirectional energy conversion capabilities.

[0130] Currently, most gravity energy storage systems suffer from intermittent charging and discharging because they rely on lifting and lowering heavy objects to convert potential energy. The rail-mounted dual-drive bulk material conveying system and its gravity flow energy storage system described in this embodiment are a new type of mechanical gravity energy storage technology. This technology aims to utilize bulk energy storage bodies to provide a continuous gravity flow, thereby achieving a continuous energy flow. This addresses the intermittent nature, difficult site selection, and high investment challenges of existing gravity energy storage.

[0131] The track-type dual-drive bulk material conveying system and its gravity flow energy storage system described in this embodiment have the following advantages:

[0132] 1. Apply the conveying principle in the field of bulk material transportation to the field of gravity energy storage to achieve continuous gravity flow energy storage.

[0133] 2. Unlike conventional belt conveyors, which are driven by belts, this solution utilizes a reel 610 to drive the conveyor belt 310 and a steering wheel 620 to drive the traction cable 210. This dual-drive system transfers bulk materials loaded on the conveyor belt 310, effectively increasing the conveyor belt 310's carrying capacity. The traction cable 210 and the conveyor belt 310 jointly drive and pull the bulk materials loaded on the conveyor belt 310. The supporting structure 100 supports all the carriers 320, which in turn carry the bulk materials loaded on the conveyor belt 310. This effectively reduces or eliminates the load-bearing capacity of the conveyor belt 310 and the traction cable 210, significantly improving the stability and carrying capacity of the rail-based dual-drive bulk material conveying system. Thanks to the supporting structure 100 and traction cable 210, the conveyor belt 310 only bears a portion of the tensile stress along the travel direction, thus reducing the performance requirements of the conveyor belt 310, allowing for the use of a more economical conveyor belt 310 and significantly increasing its service life. Furthermore, the conveyor belt 310, which bears a portion of the traction force, also reduces the likelihood of failures such as longitudinal tearing and belt breakage.

[0134] 3. Traditional belt conveyors use rollers to support the upper and lower branch belts. When the traction belt is in operation, it drives the rollers to rotate. This embodiment uses a carrier 320 to support the conveyor belt 310. The traction rope and conveyor belt 310 are driven by the carrier 320 and the conveyor belt 310 through the traction rope. This avoids the pressure resistance between the conveyor belt 310 and the rollers and the extrusion resistance of the material passing through the rollers, significantly reducing the running resistance and improving the carrying efficiency.

[0135] 4. The rollers are replaced by a carrier 320 , which is connected to the conveyor belt 310 as a whole. When the carrier 320 runs along the load-bearing track 110 of the load-bearing structure 100 , the rolling resistance between the wheels of the carrier 320 and the load-bearing track 110 is much smaller than the rolling resistance of the rollers.

[0136] 5. Improper installation of the idler rollers will twist the conveyor belt 310, which may cause the conveyor belt 310 to deviate. In this embodiment, the carrier 320 is fixed to the conveyor belt 310, eliminating the problem of conveyor belt deviation.

[0137] 6. The rollers are arranged along the entire conveyor line, and inspection and maintenance require a lot of manpower, material resources and time. In this embodiment, the carrier 320 can be inspected and repaired at a specific location.

[0138] 7. To coordinate with the traction rope, an innovative integrated steering wheel 620 + drum 610 is designed. The steering wheel 620 and drum 610 are installed on the same axis. The diameters of the steering wheel 620 and drum 610 match the corresponding wire rope diameter and conveyor belt 310 thickness. Another innovative design is that the load beam 321 of the carrier 320 is directly embedded in the conveyor belt 310 during the production process of the conveyor belt 310, ensuring the stability of the load beam 321.

[0139] 8. To enable wider system applications and reduce system space requirements, a traction guide device 220 has been designed. This device elevates the lower redirecting traction section 218 to prevent it from contacting the ground. Furthermore, the upper redirecting traction section 216 shortens the distance between the upper inclined traction section 213 and the lower inclined traction section 217. Furthermore, the traction guide device 220 increases the contact angle and area between the traction rope and the steering wheel 620, enhancing friction and improving the system's transport capacity and charging and discharging power.

[0140] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
