Description

Technical Field

[0001] This utility model relates to the field of power dispatching technology, specifically to a smart grid peak shaving and valley filling dispatching device. Background Technology

[0002] The power grid load exhibits significant peak-valley differences, with peak periods easily leading to power shortages and off-peak periods resulting in energy waste. Existing dispatching systems rely on energy storage devices to store energy during off-peak periods and release it during peak periods. However, the charging and discharging efficiency and response speed of these energy storage devices directly affect dispatching effectiveness. Furthermore, wind / solar power generation is constrained by natural conditions, resulting in unstable output. Traditional systems require inverters to store electrical energy in the storage devices before connecting them to the grid. This process involves double conversion losses (mechanical energy → electrical energy → storage → release), reducing energy utilization efficiency.

[0003] Currently, energy storage devices (such as lithium batteries) generate a large amount of heat during charging and discharging. Insufficient heat dissipation can lead to accelerated battery capacity decay, increased risk of thermal runaway, and decreased system safety. Existing cooling devices have certain technical shortcomings. First, existing energy storage devices mainly rely on grid power to drive cooling devices (such as water pumps), which increases the grid load and exacerbates energy contradictions, especially during peak electricity consumption periods. If a wind and solar power-powered cooling system is used, it has to go through a long path of "wind and solar power generation → energy storage → inverter → driving water pumps", resulting in significant energy loss. Second, the structure of wind power generation (rotor rotation) contains mechanical energy that can be directly utilized, but existing technologies only convert it into electrical energy and have not explored the possibility of mechanical energy directly driving the cooling system, thus missing the space for energy-saving optimization. When wind power is insufficient, the cooling system will fail if it relies entirely on wind power. Existing technologies lack a backup drive mechanism of wind-solar complementarity + grid coordination, which cannot guarantee the continuous heat dissipation needs of energy storage devices.

[0004] In view of this, the present invention proposes a smart grid peak shaving and valley filling scheduling device. Utility Model Content

[0008] Preferably, the first transmission component includes a second rotating shaft passing through the support column, the second rotating shaft being rotatably connected to the top wall of the base, a first rotating wheel being fixedly connected to the bottom of the second rotating shaft, a plurality of first pawls arranged in a circular array being rotatably connected to the outer edge of the first rotating wheel, a first ratchet being fixedly connected to the top of the main shaft, and a plurality of the first pawls engaging with the tooth grooves of the first ratchet.

[0009] Preferably, the second transmission component includes a motor fixedly installed inside the base, the output shaft of the motor is fixedly connected to a second wheel, the outer edge of the second wheel is rotatably connected to a plurality of second pawls distributed in a circumferential array, the bottom of the main shaft is fixedly connected to a second ratchet, and the plurality of second pawls mesh with the tooth grooves of the second ratchet.

[0011] Preferably, the wind power generation structure includes a nacelle fixedly connected to the top of a support column, an impeller rotatably connected to one end of the nacelle, a first spur gear fixedly coaxially with the impeller rotatably connected to the inner side of the nacelle, a wind turbine fixedly installed on the inner side of the base, and a second spur gear fixedly connected to the input shaft of the wind turbine, the second spur gear meshing with the first spur gear.

The impeller rotation can directly convert wind energy into mechanical power for the pump body, driving the cooling water circulation, avoiding the double conversion loss of the traditional "wind energy → electric energy → motor-driven water pump", greatly improving energy utilization; when the wind power is insufficient, the energy storage device releases electrical energy to drive the motor, and the second pawl → second ratchet maintains the rotation of the main shaft, ensuring continuous cooling operation, solving the instability of single wind power drive, and realizing uninterrupted operation of the cooling system.

[0017] 2. The cooling coil is directly embedded inside the energy storage device, and together with the closed water circulation of the pump, it achieves rapid heat exchange, which reduces the core temperature of the battery, slows down the rate of capacity decay, and avoids the risk of thermal runaway.

[0019] 4. The current sensor can monitor the grid current demand in real time. When the grid current is high, it is during peak electricity demand. The processor controls the charge / discharge switch to discharge the energy storage device, which assists the grid in supplying power and alleviates the grid supply pressure. When the grid current is low, it is during off-peak electricity demand. The processor controls the charge / discharge switch to charge the energy storage device, which is then charged by the power generated by the wind turbine and photovoltaic panels. This allows surplus power to be used to charge the energy storage system, improving grid utilization. The energy storage device charges during off-peak hours and discharges during peak hours, achieving dynamic scheduling and regulation of power supply and demand. Attached Figure Description

[0023] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0024] like Figures 1-8 As shown, this embodiment proposes a smart grid peak shaving and valley filling scheduling device, including a base 1, a support column 2 fixedly connected to the top of the base 1, a wind power generation structure 3 installed on the top of the support column 2, a photovoltaic panel 4 fixedly connected to the outside of the support column 2, the wind power generation structure 3 and the photovoltaic panel 4 being electrically connected to an energy storage device 5 via an inverter, the output end of the energy storage device 5 being connected to the grid, and a cooling mechanism 6 installed on the energy storage device 5, the cooling mechanism 6 including a cooling coil 61 fixedly connected to the inside of the energy storage device 5, and the outside of the base 1... A pump body 62 is fixedly installed. The inlet end of the pump body 62 is fixedly connected to a water inlet pipe 63. The inlet end of the water inlet pipe 63 is fixedly connected to a water tank 65. The outlet end of the pump body 62 is fixedly connected to a water guide pipe 64. The outlet end of the water guide pipe 64 is connected to the inlet end of the cooling coil 61. The outlet end of the cooling coil 61 is fixedly connected to a return water pipe 66. The outlet end of the return water pipe 66 is connected to the inside of the water tank 65. The inner side of the base 1 is provided with a transmission mechanism 7 that drives the impeller of the pump body 62 to rotate by cooperating with the start of the wind power generation structure 3.

[0025] When the wind power generation structure 3 is started, the transmission mechanism 7 drives the impeller of the pump body 62 to rotate, so that the pump body 62 is in a negative pressure state, which causes the water inlet pipe 63 to draw out the cooling water inside the water tank 65, and then guide the water into the cooling coil 61 through the water guide pipe 64, thereby cooling and dissipating heat for the energy storage device 5, thus avoiding the problem of battery degradation caused by excessive internal temperature of the energy storage device 5.

[0026] Furthermore, the transmission mechanism 7 includes a mounting bracket 71 fixedly connected to the inner side of the base 1. A main shaft 72 is rotatably connected to the inner side of the mounting bracket 71. A first bevel gear 73 is fixedly connected to the main shaft 72. A first rotating shaft 74 is rotatably connected to one end of the mounting bracket 71. One end of the first rotating shaft 74 is fixedly connected to the impeller shaft of the pump body 62. A second bevel gear 75 that meshes with the first bevel gear 73 is fixedly connected to the other end of the first rotating shaft 74. A first transmission member 76 is provided at the top of the main shaft 72 to drive the main shaft 72 to rotate by cooperating with the start of the wind power generation structure 3. A second transmission member 77 is provided at the bottom of the main shaft 72 to drive the main shaft 72 to rotate.

[0027] When the wind power generation structure 3 is activated, the first transmission component 76 drives the main shaft 72 to rotate, causing the first bevel gear 73 to rotate synchronously. Since the first bevel gear 73 meshes with the second bevel gear 75, the second bevel gear 75 drives the first rotating shaft 74 to rotate synchronously, causing the impeller shaft of the pump body 62 to rotate. This drives the impeller of the pump body 62 to rotate, creating a negative pressure state inside the pump body 62. This causes the water inlet pipe 63 to draw out the cooling water from the water tank 65, and then guides the cooling water into the cooling coil 61 through the water guide pipe 64 for circulation. This achieves cooling and heat dissipation for the energy storage device 5, preventing the battery from degrading due to excessively high internal temperature.

[0028] Furthermore, the first transmission component 76 includes a second rotating shaft 761 penetrating the support column 2. The second rotating shaft 761 is rotatably connected to the top wall of the base 1. A first rotating wheel 762 is fixedly connected to the bottom of the second rotating shaft 761. A plurality of first pawls 764 arranged in a circular array are rotatably connected to the outer edge of the first rotating wheel 762. A first ratchet 763 is fixedly connected to the top of the main shaft 72. The plurality of first pawls 764 mesh with the tooth grooves of the first ratchet 763. The second transmission component 77 includes a motor 771 fixedly installed inside the base 1. The output shaft of the motor 771 is fixedly connected to the second rotating wheel 772. A plurality of second pawls 774 arranged in a circular array are rotatably connected to the outer edge of the second rotating wheel 772. A second ratchet 773 is fixedly connected to the bottom of the main shaft 72. The plurality of second pawls 774 mesh with the tooth grooves of the second ratchet 773. The tooth groove opening directions of the first ratchet 763 and the second ratchet 773 are the same. The number of first pawls 764 and second pawls 774 is the same.

[0029] The activation of the wind power generation structure 3 causes the second shaft 761 to rotate synchronously, which in turn causes the first impeller 762 to rotate synchronously. This causes all the first pawls 764 to rotate circumferentially synchronously, applying rotational force to the first ratchet 763. Consequently, the first ratchet 763 drives the main shaft 72 to rotate, causing the first bevel gear 73 to rotate synchronously. Since the first bevel gear 73 meshes with the second bevel gear 75, the second bevel gear 75 drives the first shaft 74 to rotate synchronously, causing the impeller shaft of the pump body 62 to rotate. This drives the pump to rotate. The impeller of pump body 62 rotates, creating a negative pressure inside pump body 62. This causes the water inlet pipe 63 to draw cooling water from inside water tank 65, and then guides the cooling water into cooling coil 61 through water guide pipe 64 for circulation. This achieves cooling and heat dissipation for energy storage device 5, preventing excessive internal temperature of energy storage device 5 from causing battery degradation. The kinetic energy of pump body 62 comes directly from the mechanical energy of wind power generation structure 3. This eliminates the need for wind energy to be converted into mechanical energy and then into electrical energy to drive pump body 62, reducing intermediate conversion links and thus greatly reducing energy loss. When the wind power generation structure 3 stops, the energy storage device 5 can power the motor 771 to start, driving the second rotor 772 to rotate, causing all the second pawls 774 to rotate synchronously in the circumferential direction. This causes the second pawls 774 to apply rotational force to the second ratchet 773, which in turn causes the second ratchet 773 to drive the main shaft 72 to rotate, causing the first bevel gear 73 to rotate synchronously. Since the first bevel gear 73 meshes with the second bevel gear 75, the second bevel gear 75 drives the first rotating shaft 74 to rotate synchronously, causing the impeller shaft of the pump body 62 to rotate. This drives the impeller of the pump body 62 to rotate, creating a negative pressure inside the pump body 62. This causes the water inlet pipe 63 to draw out the cooling water from the water tank 65, and then guides the cooling water into the cooling coil 61 through the water guide pipe 64 for circulation, thereby cooling and dissipating heat from the energy storage device 5.

[0030] Furthermore, the wind power generation structure 3 includes a nacelle 31 fixedly connected to the top of the support column 2. One end of the nacelle 31 is rotatably connected to an impeller 32. The inner side of the nacelle 31 is rotatably connected to a first spur gear 33, which is coaxially fixed to the impeller 32. A wind turbine generator 34 is fixedly installed on the inner side of the base 1. The input shaft of the wind turbine generator 34 is fixedly connected to a second spur gear 35, which meshes with the first spur gear 33. The wind power generation structure 3 also includes a third bevel gear 36 coaxially fixed to the impeller 32. The top of the second rotating shaft 761 is fixedly connected to a fourth bevel gear 37, which meshes with the third bevel gear 36. The gear ratio of the second spur gear 35 to the first spur gear 33 is 1:10, and the gear ratio of the fourth bevel gear 37 to the third bevel gear 36 is 1:15.

[0031] When the wind is strong, the impeller 32 rotates under the action of the wind, causing the first spur gear 33 to rotate, which in turn causes the second spur gear 35 to drive the input shaft of the wind turbine 34 to rotate, thus enabling the wind turbine 34 to generate electricity and store the electrical energy in the energy storage device 5. During the rotation of impeller 32, third bevel gear 36 rotates synchronously, causing fourth bevel gear 37 to rotate synchronously, which in turn causes second shaft 761 to rotate synchronously, and first impeller 762 to rotate synchronously. This causes all first pawls 764 to rotate synchronously in the circumferential direction, applying rotational force to first ratchet 763. Consequently, first ratchet 763 drives main shaft 72 to rotate, causing first bevel gear 73 to rotate synchronously. Since first bevel gear 73 meshes with second bevel gear 75, second bevel gear 75 drives first shaft 74 to rotate synchronously, causing pump body 6 to rotate synchronously. The impeller shaft of 2 rotates, which drives the impeller of pump body 62 to rotate, creating a negative pressure inside pump body 62. This causes the water inlet pipe 63 to draw out the cooling water from inside water tank 65, and then guide the cooling water into cooling coil 61 through water guide pipe 64 for circulation. This achieves cooling and heat dissipation for energy storage device 5, preventing excessive internal temperature of energy storage device 5 from causing battery degradation. The kinetic energy of pump body 62 comes directly from the mechanical energy of wind power generation structure 3, eliminating the need for wind energy to be converted into mechanical energy and then into electrical energy to drive pump body 62. This reduces intermediate conversion links and greatly reduces energy loss.

[0032] Furthermore, a wind sensor is fixedly connected to the outside of the nacelle 31, a charge / discharge switch is installed on the energy storage device 5, the output end of the charge / discharge switch is electrically connected to the motor 771, a control panel is fixedly connected to the outside of the base 1, the control panel includes a processor, the wind sensor is signal-connected to the processor, and the processor is signal-connected to a current sensor connected to the power grid.

[0033] Working principle: The current sensor can monitor the grid current demand in real time. When the grid current is high, it is the peak of electricity consumption. The processor controls the charging and discharging switch to make the energy storage device 5 discharge, which assists the grid in supplying power and reduces the pressure on the grid. When the grid current is low, it is a time of low electricity demand. The processor controls the charge and discharge switch to charge the energy storage device 5, so that the wind turbine 34 and the photovoltaic panel 4 can charge the energy storage device 5. In this way, surplus electricity can be used to charge the energy storage system, improve the grid utilization rate, and enable the energy storage device 5 to charge during low electricity demand and discharge during peak demand, so as to realize the dynamic scheduling and regulation of power supply and demand. When the wind is strong, the impeller 32 rotates under the action of the wind, causing the first spur gear 33 to rotate. This causes the second spur gear 35 to drive the input shaft of the wind turbine 34 to rotate, thus enabling the wind turbine 34 to generate electricity and store the electrical energy in the energy storage device 5. During the rotation of the impeller 32, the third bevel gear 36 rotates synchronously, causing the fourth bevel gear 37 to rotate synchronously, causing the second shaft 761 to rotate synchronously, and causing the first impeller 762 to rotate synchronously. This causes all the first pawls 764 to rotate synchronously in the circumferential direction, so that the first pawls 764 apply rotational force to the first ratchet 763, thereby causing the first ratchet 763 to drive the main shaft 72 to rotate, and causing the first bevel gear 73 to rotate synchronously. A bevel gear 73 meshes with a second bevel gear 75, causing the second bevel gear 75 to drive the first rotating shaft 74 to rotate synchronously, which in turn causes the impeller shaft of the pump body 62 to rotate. This drives the impeller of the pump body 62 to rotate, creating a negative pressure inside the pump body 62. This allows the water inlet pipe 63 to draw out the cooling water from the water tank 65, and then guide the cooling water into the cooling coil 61 through the water guide pipe 64 for circulation. This achieves cooling and heat dissipation for the energy storage device 5, preventing the battery from degrading due to excessively high internal temperature. The kinetic energy of the pump body 62 comes directly from the mechanical energy of the wind power generation structure 3, eliminating the need for wind energy to be converted into mechanical energy and then into electrical energy to drive the pump body 62. This reduces intermediate conversion steps and greatly reduces energy loss. The wind sensor detects wind force in real time. In the wind-off state, the processor controls the charge / discharge switch to supply power to the motor 771 from the energy storage device 5. After the motor 771 starts, it drives the second wheel 772 to rotate, causing all the second pawls 774 to rotate circumferentially in sync. This causes the second pawls 774 to apply rotational force to the second ratchet 773, which in turn causes the second ratchet 773 to drive the main shaft 72 to rotate. This causes the first bevel gear 73 to rotate synchronously. Since the first bevel gear 73 meshes with the second bevel gear 75, the second bevel gear 75 drives the first rotating shaft 74 to rotate synchronously, causing the impeller shaft of the pump body 62 to rotate. This drives the impeller of the pump body 62 to rotate, creating a negative pressure inside the pump body 62. This causes the water inlet pipe 63 to draw out the cooling water from the water tank 65, and then guides the cooling water into the cooling coil 61 through the water guide pipe 64 for circulation, thereby cooling and dissipating heat from the energy storage device 5.

[0034] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
