Description

Technical Field

[0001] The present invention relates to the technical field of electric power dispatching, and in particular to a combined device for multi-energy supply and dispatching. Background Art

[0002] The main components of multi-energy complementary devices include multiple energy sources (such as solar energy, wind energy, hydropower, natural gas, etc.), networks (energy transmission networks), loads (energy loads), storage (energy storage devices) and related communication and information infrastructure. Through mutual cooperation and complementarity, efficient energy utilization is achieved. Various renewable energy sources are collected through different energy collection equipment (such as solar panels, wind turbines, etc.). The collected energy is converted into electrical energy or other forms of energy through conversion equipment (such as inverters, generators, etc.) and stored for subsequent deployment and use. Energy storage devices (such as batteries, pumped storage power stations, etc.) store energy when energy is surplus and release energy when energy is short to balance energy supply and demand. Through energy storage devices and intelligent scheduling systems, the supply and consumption of various energy sources are optimized according to energy demand and supply conditions, and the complementarity and synergy between energy sources are achieved to achieve efficient energy utilization.

[0003] In various multi-energy supply and dispatching devices, energy storage equipment, as a key device for coupling, temporary storage and release between different energy sources, plays an irreplaceable role in the entire multi-energy supply and dispatching device. In existing multi-energy supply and dispatching devices, when battery energy storage is used, high thermal management requirements and high cost investment are required. When pumped storage is used, the terrain is required to have a high drop, and high requirements are placed on the terrain and environment. When flywheel energy storage is used, the energy loss increases with the extension of energy storage time. Therefore, it is necessary to design a combined energy supply and dispatching device to solve the technical problems existing in the above-mentioned existing multi-energy supply and dispatching devices. Summary of the Invention

[0004] In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by the present invention is: to provide a combined multi-energy supply and scheduling device to at least solve one of the problems existing in the existing multi-energy supply and scheduling devices, namely, high investment in energy storage equipment, high requirements on terrain environment, and gradually increasing energy consumption loss as the storage time increases.

[0005] In order to solve the above technical problems, the present invention adopts a technical solution: a combined device for multi-energy supply and scheduling, including a base plate, a support plate vertically arranged on the base plate, a rotating shaft 1 horizontally arranged and fixedly connected to the support plate, and a conversion part arranged on the base plate, the conversion part includes a rotating wheel rotatably connected to the rotating shaft 1, an electric motor driving the rotating wheel to rotate, an electric motor for generating electricity and a coil spring sleeved outside the rotating shaft 1, one end of the coil spring is fixedly connected to the rotating wheel, and the other end of the coil spring is fixedly connected to the rotating shaft 1.

[0006] In this solution, when energy is abundant, each energy source is converted into electrical energy, and then the electric motor drives the rotating wheel to rotate and compress the spring, converting the electrical energy into elastic potential energy of the spring for storage. When external energy supplement is needed, the elastic potential energy of the spring is converted into rotational kinetic energy, and then the rotational kinetic energy is converted into electrical energy through a generator to supply power to the power grid. This solution has the advantages of simple device structure, small space occupation, less terrain restrictions on the construction and installation of the device, and energy consumption loss during energy storage does not increase with the extension of energy storage time.

[0007] Furthermore, the conversion part also includes a locking mechanism arranged on the base plate for locking the rotating wheel, the locking mechanism includes a cylinder arranged in the base plate and a socket arranged on the rotating wheel, the output shaft of the cylinder is arranged along the radial direction of the rotating wheel, and the output shaft of the cylinder is coaxially fixed with a plug rod, and the socket is arranged corresponding to the plug rod.

[0008] Furthermore, a plurality of the conversion parts are arranged in sequence on the bottom plate along the axis of the first rotating shaft.

[0009] Furthermore, the coil springs between adjacent conversion parts are compressed in opposite directions so that when the coil springs on adjacent conversion parts are compressed, the torques generated on the rotating shaft 1 cancel each other out. This arrangement can prevent the rotating shaft 1 from being twisted and deformed due to excessive torque in a single direction.

[0010] Furthermore, the rotating wheel includes a large wheel segment and a small wheel segment coaxially arranged with the large wheel segment, the diameter of the small wheel segment is smaller than that of the large wheel segment, the socket is arranged on the small wheel segment, and rolling support members are symmetrically arranged on the bottom plate, and the rolling support members are in contact with the small wheel segment for supporting the rotating wheel.

[0011] Furthermore, the rolling support member includes a roller seat and a support roller arranged on the roller seat, the support roller is rotatably connected to the roller seat through a second rotating shaft, the second rotating shaft is rotatably connected to the roller seat, the support roller is unidirectionally rotatably connected to the second rotating shaft through a one-way bearing one, and a speed regulating mechanism for limiting the rotational speed of the rotating wheel is provided on the rolling support member.

[0012] Furthermore, the speed regulation mechanism includes a slideway arranged along the radial direction of the rotating shaft 2, a slider and a tension spring arranged in the slideway, one end of the slideway passes through the rotating shaft 2, and the other end of the slideway is a blind end, the slider is slidably connected to the slideway, one end of the tension spring is fixedly connected to the slider, and the other end of the tension spring is fixedly connected to the blind end of the slideway, the center of mass of the slider is eccentrically arranged with the axis of the rotating shaft 2, and a friction block is provided at the end of the slider away from the slideway.

[0013] Furthermore, the electric motor is arranged on one side of the rotating shaft one, the generator is arranged on the other side of the rotating shaft one opposite to the engine, the outer wall of the large wheel segment is provided with gear teeth, the output shaft of the electric motor is provided with a driving gear meshing with the large wheel segment, and the input shaft of the generator is provided with a driven gear meshing with the large wheel segment.

[0014] Furthermore, the output shaft of the motor is connected to the driving gear for one-way rotation via a second one-way bearing, and the input shaft of the generator is connected to the driven gear for one-way rotation via a third one-way bearing. When the output shaft of the motor rotates in a first direction, the driving gear and the output shaft of the motor rotate synchronously, driving the large wheel section to rotate in a second direction to compress the coil spring. When the large wheel section rotates in the first direction under the elastic force of the coil spring and drives the driven gear to rotate, the driven gear drives the input shaft of the generator to rotate synchronously. When the large wheel section rotates in the second direction to compress the coil spring, the driven gear rotates relative to the input shaft of the generator.

[0015] Furthermore, the friction block is made of wear-resistant rubber.

[0016] In this solution, when energy is abundant, each energy source is converted into electrical energy, and then the rotating wheel is driven by the motor to rotate and compress the coil spring, converting the electrical energy into elastic potential energy of the coil spring for storage. When external energy supplement is needed, the elastic potential energy of the coil spring is converted into rotational kinetic energy, and then the rotational kinetic energy is converted into electrical energy through the generator to supply power to the power grid. When the output shaft of the motor rotates in the first direction, under the action of the one-way bearing 2, the driving gear and the output shaft of the motor rotate synchronously, driving the large wheel segment to rotate in the second direction to compress the coil spring. At this time, the support roller in contact with the small wheel segment is in a forward rotation state. Under the action of the one-way bearing 1, the support roller can rotate relative to the rotating shaft 2, and the driven gear is engaged with the large wheel segment so that the driven gear rotates with the rotating wheel. Under the action of the one-way bearing 3, the driven gear can rotate relative to the input shaft of the generator, and the input shaft of the generator does not rotate with the driven gear. When the coil spring shrinks to a certain extent, the motor is controlled to align the socket with the output shaft of the cylinder, and the cylinder 1 is operated so that the output shaft of the cylinder 1 is inserted into the socket and the motor is stopped.

[0017] When it is necessary to replenish energy to the power grid, the operating cylinder causes the output shaft of the cylinder to retract and leave the socket. When the rotating wheel rotates in the first direction under the elastic force of the coil spring, it drives the driven gear on the input of the generator to rotate. Under the action of the one-way bearing three, the input shaft of the generator rotates synchronously with the driven gear to enable the generator to generate electricity. At this time, the supporting roller in contact with the small wheel segment is in a reverse rotation state. Under the action of the one-way bearing one, the supporting roller rotates synchronously with the rotating shaft two. When the rotating wheel rotates too fast in the first direction under the elastic force of the coil spring, the slider slides under the action of centrifugal force, thereby increasing the friction between the friction block and the roller seat, thereby preventing the speed of the rotating shaft two from further increasing, thereby achieving the purpose of limiting the speed of the rotating wheel.

[0018] Compared with the existing technology, this solution has the advantages of simple device structure, small space occupation, less terrain restrictions on the construction and installation of the device, and energy consumption loss during energy storage does not increase with the extension of energy storage time.

[0035] To make the purpose, technical solutions, and advantages of this application more clear, the technical solutions of this application will be clearly and completely described below in conjunction with the specific embodiments of this application and the corresponding drawings. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0036] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in this specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0037] A combined device for multi-energy supply and dispatching in this embodiment, such as Figure 1-Figure 7 As shown, it includes a base plate 10, a support plate 20 vertically arranged on the base plate 10, a rotating shaft 30 horizontally arranged and fixedly connected to the support plate 20, and a plurality of conversion parts 40 arranged on the base plate 10 in sequence along the axis of the rotating shaft 30. In this embodiment, four conversion parts 40 are provided along the axis of the rotating shaft 30. In other feasible embodiments, more or fewer conversion parts 40 can be provided according to energy storage needs. Examples are not given one by one here. The conversion part 40 is used to convert electrical energy into elastic potential energy for storage, and when external energy replenishment is needed, the stored elastic potential energy is converted into electrical energy to supply power to the grid for energy replenishment.

[0038] The base plate 10 is a rectangular plate. The support plate 20 is vertically disposed at one end of the base plate 10, with the lower end of the support plate 20 fixedly connected to the base plate 10. The rotating shaft 30 is horizontally disposed along the length of the base plate 10, with one end of the rotating shaft 30 fixedly connected to the support plate 20. Alternatively, a supporting plate 20 may be vertically fixedly connected to each end of the base plate 10 in the lengthwise direction, so that each end of the rotating shaft 30 is fixedly connected to a supporting plate 20. The conversion unit 40 includes a rotating wheel 41 rotatably connected to the rotating shaft 30, a motor 42 for driving the rotating wheel 41 to rotate, the motor 42 for generating electricity, a coil spring 44 disposed outside the rotating shaft 30, a locking mechanism disposed on the base plate 10 for locking the rotating wheel 41, and a rolling support member 46 disposed on the base plate 10 for supporting the rotating wheel 41. One end of the coil spring 44 is fixedly connected to the rotating wheel 41, and the other end of the coil spring 44 is fixedly connected to the rotating shaft 1 30. The coil spring 44 can convert other forms of energy into electrical energy and drive the rotating wheel 41 to rotate and compress the coil spring 44 via the motor 42, thereby causing the coil spring 44 to deform and store energy. In this solution, the compression and energy storage directions of the coil springs 44 between adjacent conversion parts 40 are arranged in opposite directions so that when the coil springs 44 on adjacent conversion parts 40 are compressed, the torques generated on the rotating shaft 1 30 are opposite. That is, when the rotating wheel 41 on one conversion part 40 rotates in a first direction, causing the corresponding coil spring 44 to compress and store energy, the rotating wheel 41 on the adjacent conversion part 40 rotates in a direction opposite to the first direction, causing the corresponding coil spring 44 to compress and store energy. This prevents the rotating shaft 1 30 from being twisted and deformed by excessive torque superimposed in a single direction.

[0039] Combine Figure 1 、 Figure 2 As shown, the rotating wheel 41 is coaxially arranged with the rotating shaft 30, and the rotating shaft 30 passes through the rotating wheel 41 and is rotatably connected to the rotating wheel 41.

A small roller 4523 is rotatably provided on the upper end of the upper rod 4522. The axis of the small roller 4523 is arranged parallel to the axis of the small wheel segment 412. A lower retaining ring 4527 is radially protruded from the lower end of the upper rod 4522. An upper retaining ring 4526 is radially protruded from the inner wall of the upper end of the slide 4524. The outer wall of the lower retaining ring 4527 is slidably connected to the inner wall of the slide 4524. The inner wall of the upper retaining ring 4526 is slidably connected to the outer wall of the upper rod 4522. A spring 1 4525 is provided at the lower end of the upper rod 4522. The upper end of the spring 1 4525 is fixedly connected to the lower end of the upper rod 4522, and the lower end of the spring 1 4525 is fixedly connected to the bottom wall of the slide 4524. The insertion hole 4121 is arranged along the radial direction of the small wheel segment 412 and corresponds to the upper rod 4522. The inner diameter of the insertion hole 4121 is larger than the outer diameter of the small roller 4523. When the rotating wheel 41 rotates to a suitable position, the insertion hole 4121 is aligned with the upper rod 4522.

[0041] like Figure 1 As shown, the rolling support member 46 is symmetrically arranged on both sides of the rotating wheel 41. The rolling support member 46 contacts the small wheel segment 412 to support the rotating wheel 41. Figure 4-Figure 6As shown, the rolling support member 46 includes a roller seat 461 and a support roller 462 arranged on the roller seat 461, the roller seat 461 is fixedly connected to the base plate 10, the support roller 462 is rotatably connected to the roller seat 461 through a second rotating shaft 463, the second rotating shaft 463 is rotatably connected to the roller seat 461, the support roller 462 is unidirectionally rotatably connected to the second rotating shaft 463 through a one-way bearing 1 464, the support roller 462 is a rubber wheel, and the support roller 462 is a rubber wheel that contacts the outer wall of the small wheel segment 412 to support the entire rotating wheel 41, and a speed regulating mechanism for limiting the rotation speed of the rotating wheel 41 is provided on the rolling support member 46, and the speed regulating mechanism includes A slide 4631 is arranged radially along the second rotating shaft 463, and a slider 4632 and a tension spring 4633 are arranged in the slide 4631. One end of the slide 4631 passes through the second rotating shaft 463, and the other end of the slide 4631 is a blind end. The slider 4632 is slidingly connected to the slide 4631, one end of the tension spring 4633 is fixedly connected to the slider 4632, and the other end of the tension spring 4633 is fixedly connected to the blind end of the slide 4631. The center of mass of the slider 4632 is eccentrically arranged with the axis of the second rotating shaft 463. A friction block 4634 is provided at the end of the slider 4632 away from the slide 4631, and the friction block 4634 is made of wear-resistant rubber.

[0042] like Figure 1 、 Figure 3As shown, the motor 42 is arranged on one side of the rotating shaft 30, and the motor 42 is fixedly connected to the base plate 10. The generator 43 is arranged on the other side of the rotating shaft 30 opposite to the engine, and the generator 43 is fixedly connected to the base plate 10. A driving gear 421 engaged with the large wheel segment 411 is provided on the output shaft of the motor 42, and a driven gear 431 engaged with the large wheel segment 411 is provided on the input shaft of the generator 43. The output shaft of the motor 42 is connected to the driving gear 421 for unidirectional rotation via a one-way bearing 2, and the input shaft of the generator 43 is connected to the driven gear 431 for unidirectional rotation via a one-way bearing 3. When the output shaft of the motor 42 rotates in the first direction, the driving gear 421 rotates synchronously with the output shaft of the motor 42 to drive the large wheel section 411 to rotate in the second direction to compress the coil spring 44. When the output shaft of the motor 42 rotates in the second direction, the one-way bearing 2 enables the output shaft of the motor 42 to rotate relative to the driving gear 421, and thus at this time the motor 42 cannot transmit torque to the driving gear 421, and the rotating wheel 41 cannot rotate in the first direction under the drive of the motor 42, so as to prevent the coil spring 44 from being expanded in the reverse direction and causing damage to the coil spring 44. When the rotating wheel 41 rotates in the second direction under the drive of the motor 42, the driven gear 431 meshed with the large pulley 411 rotates in the first direction. Under the action of the one-way bearing 3, the driven gear 431 can now rotate relative to the input shaft of the generator 43, but the driven gear 431 cannot transmit torque to the input shaft of the generator 43. When the large pulley 411 rotates in the first direction under the elastic force of the coil spring 44, driving the driven gear 431 in the second direction, under the action of the one-way bearing 3, the driven gear 431 drives the input shaft of the generator 43 to rotate synchronously, causing the generator to generate electricity. An electromagnetic clutch is provided on the output shaft of the motor 42 to control the on / off torque of the output shaft of the motor 42. When the motor 42 is used to drive the rotating wheel 41, the electromagnetic clutch is controlled to be in the engaged state, transmitting the torque of the motor 42 to the rotating wheel 41. When the coil spring 44 releases energy to drive the rotating wheel 41 and thus drive the generator 43 to generate electricity, the electromagnetic clutch is controlled to be in the disengaged state, preventing the driving gear 421 from rotating the output shaft of the motor 42.

[0043] In this solution, when energy is abundant, each energy source is converted into electrical energy, and then the motor 42 drives the rotating wheel 41 to rotate and compress the coil spring 44, converting the electrical energy into the elastic potential energy of the coil spring 44 for storage. When external energy supplement is needed, the elastic potential energy of the coil spring 44 is converted into rotational kinetic energy, and then the rotational kinetic energy is converted into electrical energy through the generator 43 to supply power to the power grid. When the output shaft of the motor 42 rotates in the first direction, the control makes the output shaft 451 of the cylinder 45 contract so that the small roller 4523 on the upper rod 4522 leaves the outer wall of the small segment wheel 412. Under the action of the one-way bearing 2, the driving gear 421 rotates synchronously with the output shaft of the motor 42, driving the rotating wheel 41 to rotate in the second direction to compress the coil spring 44 so that the coil spring 44 stores energy. At this time, the supporting roller 462 in contact with the small wheel segment 412 is in a forward rotation state. Under the action of the one-way bearing 1 464, the supporting roller 462 can rotate relative to the rotating shaft 2 463, and the rotating shaft 2 463 does not rotate with the supporting roller 462. The driven gear 431 is meshed with the large wheel segment 411 so that the driven gear 431 rotates synchronously with the rotating wheel 41, but under the action of the one-way bearing 3, the driven gear 431 can rotate relative to the input shaft of the generator 43. The input shaft of the generator 43 When the socket 4121 on the small wheel segment 412 rotates to align with the upper rod 4522, the upper end of the upper rod 4522 is inserted into the socket 4121 under the elastic force of spring 1 4525, and the rotating wheel 41 is forced to stop rotating, and the coil spring 44 is in an energy storage state. It should be noted that when the rotating wheel 41 rotates, the support rollers 462 on both sides of the rotating wheel 41 rotate in opposite directions. Therefore, it is necessary to set the one-way bearing 1 464 on both sides of the rotating wheel 41 to rotate in opposite directions when the corresponding rotating shaft 2 463 is in a stuck state.

[0044] When it is necessary to supply energy to the power grid, the cylinder 45 is operated to shrink the output shaft 451 of the cylinder 45 so that the upper rod 4522 leaves the socket 4121. When the rotating wheel 41 rotates in the first direction under the elastic force of the coil spring 44, it drives the driven gear 431 to rotate. Under the action of the one-way bearing 3, the input shaft of the generator 43 rotates synchronously with the driven gear 431 so that the generator 43 generates electricity to supply electricity to the power grid. When the rotating wheel 41 rotates in the first direction under the elastic force of the coil spring 44, the supporting roller 462 in contact with the small wheel segment 412 is in the reverse direction. In the rotating state, under the action of the one-way bearing 464, the supporting roller 462 and the second rotating shaft 463 rotate synchronously. When the rotating wheel 41 rotates too quickly in the first direction driven by the elastic force of the coil spring 44, the second rotating shaft 463 also rotates at a higher speed, increasing the centrifugal force on the slider 4632. Under the action of the centrifugal force, the slider 4632 slides, increasing the friction between the friction block 4634 and the roller seat 461, thereby preventing the rotation speed of the second rotating shaft 463 from further increasing, thereby limiting the rotation speed of the rotating wheel 41. It can be understood that when the second rotating shaft 463 is not rotating, the tension spring 4633 forces the slider 4632 to a position where the friction block 4634 does not contact the roller seat 461.

[0045] Compared with the existing technology, this solution has the advantages of simple device structure, small space occupation, less terrain restrictions on the construction and installation of the device, energy consumption loss during energy storage does not increase with the extension of energy storage time, can prevent the coil spring from being damaged by reverse expansion, and can automatically control the rotation speed of the rotating wheel when the elastic potential energy of the coil spring is released.

[0046] In this solution, when the motor needs to be stopped during the compression of the coil spring, there is no need to deliberately control the motor to align the socket with the insertion rod before stopping. When the motor is stopped at any time and the electromagnetic clutch on the motor is controlled to be disconnected, the initial speed of the rotating wheel when it starts to rotate under the elastic force of the coil spring is relatively low. In this solution, the rotating wheel does not rotate more than one circle at the beginning before the insertion rod can be inserted into the socket. Therefore, the impact force of the low-speed rotating wheel on the insertion rod is relatively small, which can effectively prevent the insertion rod from being damaged.

[0047] The above are only embodiments of the present invention, and the common knowledge such as the specific structure and characteristics of the scheme are not described in detail here. It should be pointed out that for those skilled in the art, without departing from the structure of the present invention, several variations and improvements can be made, which should also be regarded as the scope of protection of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent.
