Description

Technical Field

[0001] The present invention relates to the technical field of wind, solar and storage complementarity, and specifically to a distributed energy generation system of wind, solar and storage complementarity and a control method thereof. Background Art

[0002] Energy is an important material basis for national economic development and people's lives. In the past 200 years, the energy system based on fossil fuels such as coal, oil, and natural gas has greatly promoted the development of human society. However, while using fossil fuels, humans have also brought serious environmental pollution and ecosystem damage. In recent years, countries around the world have gradually realized the importance of energy to mankind, and have become more aware of the damage to the environment and ecosystem during the use of conventional energy. Countries have begun to govern and alleviate the deteriorating environment according to their national conditions, and have made the development and utilization of renewable and pollution-free new energy an important part of sustainable development. The wind-solar complementary power generation system utilizes the complementarity of wind and solar energy resources and is a new type of energy generation system with a high cost-effectiveness. It has a good application prospect.

[0003] At present, the energy generated by wind turbines and solar arrays is transmitted to the power transformer through the photovoltaic power generation grid-connected controller. The power transformer transmits the electricity to the high-voltage transmission network. When the voltage of the high-voltage transmission network is sufficient, the photovoltaic power generation grid-connected controller will transmit the energy to the wind and solar storage box to charge the lithium battery in the wind and solar storage box. However, due to the limited capacity of lithium batteries, when an independent lithium battery is full, another lithium battery needs to be charged. When the high-voltage transmission network is short of power, the fully charged lithium battery also needs to release the electricity to the photovoltaic power generation grid-connected controller, and then release the energy to the power transformer through the photovoltaic power generation grid-connected controller. This method is relatively cumbersome, and the frequent charging and discharging of a single lithium battery will lead to a reduction in the service life of the battery, and the lithium battery has poor energy storage effect. Therefore, we urgently need a distributed energy generation system with complementary wind, solar and storage and a control method thereof to solve the above problems. Summary of the invention

[0014] A control method for a distributed energy generation system with complementary wind, solar and storage, the steps are as follows:

[0015] S1: Under normal conditions of the equipment, there is a lithium battery charging pack in the wind and solar storage box. When charging, the lithium battery charging pack is located on the placement plate, driven by the lifting frame to move upward, and moved into the rectangular frame. The hydraulic cylinder three in the rectangular frame will drive the corresponding limit plate two to contact and limit the left and right sides and the rear side of the lithium battery charging pack. The hydraulic cylinder two in the rectangular frame will drive the charging panel to move toward the lithium battery charging pack, and electrically connect the charging port on the charging panel with the charging port on the lithium battery charging pack, and introduce energy through the charging device, and transmit the energy to the charging port on the charging panel through the transformer and release it, thereby realizing the charging process for this lithium battery charging pack. When the lithium battery charging pack is fully charged, the hydraulic cylinder two will drive the charging panel to retract, so that the charging port on the charging panel is separated from the charging port on the lithium battery charging pack. At this time, the lithium battery charging pack is fully charged and is stored in the rectangular frame;

[0016] At this time, three fully charged lithium battery charging packs are also arranged in the storage slot arranged in the lithium battery placement device in the energy storage box. The lithium battery charging packs in the storage slot are clamped by the limit plate four driven by the hydraulic cylinder four on the L-shaped plate and stored in the storage slot. When the system in the discharge device receives an external instruction to transmit energy outward, the drive guide rail three drives the drive block three to move downward, and the hydraulic cylinder five drives the discharge panel to move upward, so that the discharge port on the lithium battery charging pack is electrically connected with the discharge port on the discharge panel, so that the discharge process is completed through the operation of the discharge device. It should be noted that because the energy supplemented to the outside needs to be calculated by the discharge device, when the calculated energy only needs to enable two lithium battery charging packs to discharge, the remaining lithium battery charging pack is still in the storage state and does not perform the discharge process.

[0017] S2: When one of the three lithium battery packs in the lithium battery placement device has a low power, for example, when one of the two activated lithium battery packs has a low power, the discharge device will activate the remaining lithium battery pack to move downward by driving the drive block four on the drive rail four, and the hydraulic cylinder five drives the discharge panel to move upward and electrically connects with the discharge port of the lithium battery pack through the discharge port. It should be noted that the above process is applied to the relay of the lithium battery pack during the discharge operation, and the other is when the discharge is completed and the lithium battery pack is replaced. In this case, the three lithium battery packs are all in the placement state, and the discharge device will arrange the replacement order according to the remaining power of the lithium battery pack;

[0018] The three driving guide rails three will drive the driving block three to move toward the direction of the wind and solar storage box, and the movement stroke of the driving guide rail three is greater than the lithium battery placement device. During the operation of the driving block three in the driving guide rail three, the hydraulic cylinder three in the rectangular frame will drive the limit plate two to reset, thereby contacting the limit of the lithium battery charging pack on the placement plate. At this time, the placement plate on the lifting frame drives the fully charged lithium battery charging pack to descend, thereby vacating an operating position for the U-shaped limit frame. When the placement plate on the lifting frame runs to the bottom of the U-shaped limit frame, the side of the lithium battery charging pack is flush with the U-shaped limit frame. At this time, the two U-shaped limit frames are on the driving guide rail one and the corresponding driving block one. The U-shaped limit frame is driven to perform relative movement. When the U-shaped limit frame wraps the side of the lithium battery charging pack, the limit plate 1 is driven by the hydraulic cylinder 1 to contact and clamp the lithium battery charging pack. At this time, the lifting frame drives the placement plate to drop to the lowest height. At this time, the driving guide rail 2 drives the driving block 2 to move toward the energy storage box, so that the U-shaped limit frame moves into the energy storage box. The driving motor 1 on the driving block 2 is started, and the U-shaped limit frame is driven to flip over, so that the discharge port of the lithium battery charging pack faces downward. Because the U-shaped limit frame is a semi-wrapped design, after flipping, the upper position of the lithium battery charging pack is a clampable position and is located below the driving block 3;

[0019] S3: Because there are three drive blocks three, the lithium battery charging pack is located under the middle drive block three at this time. For example, the lithium battery charging pack on the far left needs to be replaced. At this time, the drive guide rail one will drive the drive block one to move to the right, and move the lithium battery charging pack to under the rightmost drive block three. The double-headed hydraulic cylinder on the rightmost drive block three drives the limit plate three to clamp the front and rear sides of the lithium battery charging pack. At this time, the limit plate one on the hydraulic cylinder one in the U-shaped limit frame cancels the limit on the lithium battery charging pack, and is driven by the drive motor one on the drive block two to rotate from a vertical state to a horizontal state, and is retracted through the drive block two on the drive guide rail two. At this time, the drive guide rail one drives the drive The moving block 1 moves to the left and moves to the position of the lithium battery charging pack that needs to be replaced. The driving block 3 at the corresponding position moves backward, and the driving block 4 on the driving guide rail 4 drives the lithium battery charging pack on the L-shaped plate to move upward. At this time, the lithium battery charging pack is inserted and placed on the side, and the double-headed hydraulic cylinder on the corresponding driving block 3 drives the limit plate 3 to clamp the lithium battery charging pack. The limit plate 4 of the hydraulic cylinder 4 cancels the clamping of the lithium battery charging pack. The driving guide rail 3 drives the driving block 3 with the lithium battery charging pack to move toward the wind and solar storage box body, and through the drive of the driving motor 2, the lithium battery charging pack that was originally on the front and rear sides is rotated to the side and placed on the left and right sides. At this time, the long board 2 The upper drive block 2 on the upper drive guide rail 2 moves toward the energy storage box, and the U-shaped limit frame is adjusted to a vertical position through the drive motor 1. At this time, the distance between the two U-shaped limit frames is larger than the distance between the lithium battery charging packs. The drive guide rail 1 drives the drive block 1 to move relatively, and the lithium battery charging pack is clamped by the upper limit plate 1 of the hydraulic cylinder 1 in the U-shaped limit frame. At this time, the upper limit plate 3 of the double-head hydraulic cylinder cancels the limit, and drives the drive motor 2 and the double-head hydraulic cylinder to move upward through the telescopic mounting ring, so that the limit plate 3 does not hinder the movement of the lithium battery charging pack. It should be noted that the telescopic mounting ring is driven by the hydraulic cylinder as a telescopic mounting bracket, which is used to fix the drive motor 2. , and is also used to move the driving motor 2. The driving motor 1 on the driving block 2 drives the U-shaped limit frame to turn over and be placed on a flat surface. At this time, the driving block 2 on the driving guide rail 2 retracts the U-shaped limit frame, and the driving block 1 on the driving guide rail 1 drives the lithium battery charging pack to move above the placement plate. At this time, the lifting frame drives the placement plate to move upward and contact the lower surface of the lithium battery charging pack. At this time, the limit plate 1 in the U-shaped limit frame cancels the clamping of the lithium battery charging pack under the drive of the hydraulic cylinder 1. This lithium battery charging pack is a lithium battery charging pack that lacks power. At this time, the fully charged lithium battery charging pack is located on the rightmost driving block 3 and is clamped by the upper limit plate 3 of the double-head hydraulic cylinder;

[0020] S4: At this time, the lifting frame drives the placement plate to drop to the lowest position again, and the driving guide rail 1 drives the driving block 1 to move to the left. When the two U-shaped limit frames are located on the left and right sides of the fully charged lithium battery charging pack, the sides of the lithium battery charging pack are located on the left and right sides, and the driving guide rail 2 drives the driving block 2 to move. The driving motor 1 on the driving block 2 drives the U-shaped limit frame to rotate. After the two U-shaped limit frames are aligned with the sides of the lithium battery charging pack, the driving guide rail 1 drives the driving block 1 to move relatively, so that the U-shaped limit frame contacts the side of the lithium battery charging pack and is clamped through the cooperation of the limiting plate 1 and the hydraulic cylinder 1. At this time, the driving motor 2 on the rightmost driving block 3 moves upward through the telescopic mounting ring, and under the drive of the driving guide rail 3, the driving block 3 is reset. At this time, the driving guide rail 1 drives the driving block 1 to move to the left, and the telescopic mounting ring on the leftmost driving block 3 moves downward, thereby making the double-headed The upper limit plate three of the hydraulic cylinder clamps the front and rear sides of the lithium battery charging pack. At this time, the limit plate one in the U-shaped limit frame cancels the limit on the lithium battery charging pack and resets it to the wind and solar storage box. At this time, driven by the drive motor two, the side of the lithium battery charging pack is flipped to the front and rear sides, and driven by the drive block three on the drive guide rail three to the storage slot, and clamped by the limit plate four driven by the hydraulic cylinder four on the L-shaped plate. The drive guide rail four drives the drive block four to move downward, and the hydraulic cylinder five drives the discharge panel to move upward, so that the discharge port of this lithium battery charging pack is electrically connected to the discharge port on the discharge panel. At the same time, the placement plate on the lifting frame drives the power-deficient lithium battery charging pack to move upward into the rectangular frame, and is limited by the upper limit plate two of the hydraulic cylinder three. The hydraulic cylinder two drives the charging port on the charging panel to move and electrically connect it to the charging port of the power-deficient lithium battery charging pack to complete the battery replacement work.

[0021] By adopting the above technical solution, the beneficial effects of the present invention are:

[0022] 1. The wind, solar and storage complementary distributed energy generation system and its control method, by setting up a battery replacement mechanism, can effectively plan the use of lithium batteries while reducing the number of times lithium batteries are used, thereby spreading the original number of times used among several lithium batteries, extending the service life of lithium batteries and improving the stability of lithium batteries in energy transmission.

[0023] 2. The distributed energy generation system with complementary wind, solar and storage and its control method, through the cooperation of the energy release mechanism, can reasonably plan the number of lithium batteries required according to the required electric energy, thereby avoiding the need to use each lithium battery and reducing unnecessary energy consumption.

Because the side of the lithium battery charging pack 8 has a certain thickness, the opening width of the U-shaped limit frame 118 is greater than the thickness of the lithium battery charging pack 8, and a portion for clamping is reserved on the side of the lithium battery charging pack 8 to avoid damage to the lithium battery charging pack 8 when the limit plate 1110 clamps the lithium battery charging pack 8 through the hydraulic cylinder 119.

[0049] The upper surface of the horizontal plate 5 is fixedly connected to a lifting frame 1111, to which a placing plate 1112 is fixedly connected, on which a lithium battery charging pack 8 is placed. The lifting frame 1111 is used to drive the placing plate 1112 to move up and down. The lifting frame 1111 is supported by a hydraulic cylinder and driven to rise and fall.

[0050] A rectangular frame 1113 is arranged inside the wind-solar storage box 1 and above the placement plate 1112. The rear side of the rectangular frame 1113 is fixedly connected to the inner wall of the wind-solar storage box 1. The left and right sides of the front side of the rectangular frame 1113 are fixedly connected to the front inner wall of the wind-solar storage box 1 through brackets 1114. A transformer 1115 is fixedly connected to the front inner wall of the wind-solar storage box 1 and is located between the two brackets 1114. The transformer 1115 is electrically connected to the charging device 13 on the wind-solar storage box 1. The front side of the rectangular frame 1113 A charging panel 1116 is provided on the inner wall, and a charging port 1117 is provided on the charging panel 1116. A hydraulic cylinder two 1118 is fixedly connected to the front inner wall of the rectangular frame 1113, and the output end of the hydraulic cylinder two 1118 is fixedly connected to the charging panel 1116. The charging panel 1116 and the transformer 1115 are electrically connected through a wiring harness. Hydraulic cylinder three 1119 are fixedly connected to the left and right sides and the rear inner wall of the rectangular frame 1113, and the output end of the hydraulic cylinder three 1119 is fixedly connected to the limiting plate two 1120.

[0051] The rectangular frame 1113 is rectangular and hollow in the middle. The rear side of the rectangular frame 1113 is connected to the rear inner wall of the wind and solar storage box 1. The front side is connected to the wind and solar storage box 1 by the bracket 1114 as a connecting bridge. The transformer 1115 acts on the middle hub, so that the power transmitted from the outside through the charging device 13 is transmitted to the charging panel 1116 through the wiring harness after passing through the transformer 1115. The hydraulic cylinder 1118 acts on the charging panel 1116 to move, so that the charging port 1117 on the charging panel 1116 is connected to the lithium battery charging pack 8. It is electrically connected to the charging port and charged. It should be noted that the opening diameter of the rectangular frame 1113 is larger than the diameter of the lithium battery charging pack 8. When the lithium battery charging pack 8 is moved into the rectangular frame 1113 through the lifting frame 1111, the placement plate 1112 also serves as a support plate at the bottom of the lithium battery charging pack 8. The output end of the hydraulic cylinder three 1119 drives and drives the limit plate two 1120 to limit the left and right sides and the rear side of the lithium battery charging pack 8. At this time, the front side of the lithium battery charging pack 8 is electrically connected to the charging port 1117 on the charging panel 1116.

[0052] Three storage slots 121 are provided in the lithium battery placement device 9, and the energy release mechanism 12 includes a driving guide rail three 122, and the three driving guide rails three 122 are all fixedly connected to the inner top wall of the energy storage box 7, and a driving block three 123 is slidably connected to the driving guide rail three 122, and the driving block three 123 and the side away from the driving guide rail three 122 are fixedly connected to a driving motor two 124 through a telescopic mounting ring 15, and the output end of the driving motor two 124 is fixedly connected to a double-headed hydraulic cylinder 125, and the two output ports of the double-headed hydraulic cylinder 125 are fixedly connected to a limiting plate three 126.

[0053] The three storage areas set in the lithium battery placement device 9 are used to provide storage locations for the lithium battery charging packs 8, wherein the number of lithium batteries that can be stored in the entire device is expanded according to actual needs. It should be noted that due to the three storage areas set in the lithium battery placement device 9 of the present application, there are three fully charged lithium battery charging packs 8, and there is a lithium battery charging pack 8 being charged in the rectangular frame 1113. When this lithium battery charging pack 8 is fully charged, charging stops, but its position is still limited in the rectangular frame 1113 and stored. Because the three fully charged lithium battery charging packs 8 still need to be discharged, and under the control of the discharge device 10, the required lithium battery charging packs 8 are discharged. For example, what is needed at this time Only two lithium battery charging packs 8 are needed to replenish the energy, so the remaining lithium battery charging pack 8 is still in storage. After the energy replenishment work is completed, the used lithium battery charging packs 8 are sorted according to the remaining power, and the low-power lithium battery charging packs 8 are replaced with the fully charged lithium battery charging packs 8 in the rectangular frame 1113. The driving guide rail three 122 is an electrically controlled driving guide rail, and the driving block three 123 in the driving guide rail three 122 moves along the Z axis. Because three lithium battery charging packs 8 are arranged in the lithium battery placement device 9, the driving guide rail three 122 needs to be matched with the driving block one 113 on the driving guide rail one 112 and the driving block two 116 on the driving guide rail two 115 to replace the low-power lithium battery charging pack 8.

[0054] A mobile clamping assembly 127 is provided in each of the three storage slots 121. The mobile clamping assembly 127 includes a driving guide rail 128. The two driving guide rails 128 are respectively fixedly connected to the left and right sides of the storage slot 121, and a driving block 129 is slidably connected to the driving guide rail 128. The two driving blocks 129 are fixedly connected to the L-shaped plate 1210. The opposite sides of the two L-shaped plates 1210 are fixedly connected to hydraulic cylinders 1211, and the output end of the hydraulic cylinder 1211 is fixedly connected to a limiting plate 1212.

[0055] The mobile clamping assembly 127 is used to clamp the lithium battery charging pack 8, wherein the moving function is to drive the lithium battery charging pack 8 to move downward when a discharge process is required. The driving guide rail 128 is an electrically controlled linear guide rail, which drives the driving block 129 to move along the Y-axis direction. The hydraulic cylinder 1211 and the limit plate 1212 are used to clamp the lithium battery charging pack 8. The horizontal plate under the L-shaped plate 1210 is used to support the bottom of the lithium battery charging pack 8. The stored lithium battery charging pack 8 is placed vertically, and the discharge port of the lithium battery charging pack 8 faces downward.

[0056] The inner bottom walls of the three storage slots 121 in the lithium battery placement device 9 are fixedly connected to the hydraulic cylinder 5 1213, and the output end of the hydraulic cylinder 5 1213 is fixedly connected to the discharge panel 1214, and the discharge panel 1214 is provided with a discharge port 1215, and the discharge port 1215 is electrically connected to the discharge device 10.

[0057] The hydraulic cylinder 5 1213 is used to drive the discharge panel 1214 to move upward, and to electrically connect the discharge port 1215 with the discharge port on the lithium battery charging pack 8 .

[0058] It should be noted that safety devices 14 are provided in the wind-solar storage box 1 and the energy storage box 7, which include necessary components such as temperature control and humidity control. The coordination of each component is controlled through the PLC control panel coordination program in the safety device 14 and the sensors carried by the components to ensure the smooth operation of the equipment. The safety device 14 is located on the wind-solar storage box 1 and the energy storage box 7.

[0059] When the wind-solar-storage complementary distributed energy generation system and its control method are working, under normal conditions of the equipment, there is a lithium battery charging pack 8 in the wind-solar-storage box 1. When charging, the lithium battery charging pack 8 is located on the placement plate 1112, driven by the lifting frame 1111 to move upward and move into the rectangular frame 1113. The hydraulic cylinder three 1119 in the rectangular frame 1113 will drive the corresponding limit plate two 1120 to contact and limit the left and right sides and the rear side of the lithium battery charging pack 8. The hydraulic cylinder two 1118 in the rectangular frame 1113 will drive the charging panel 1116 to move toward the lithium battery charging pack 8, and make the charging panel 1 The charging port 1117 on 116 is electrically connected to the charging port on the lithium battery charging pack 8, and energy is introduced through the charging device 13, and the energy is transmitted to the charging port 1117 on the charging panel 1116 through the transformer 1115 and released, thereby realizing the charging process for this lithium battery charging pack 8. When the lithium battery charging pack 8 is fully charged, the hydraulic cylinder 1118 will drive the charging panel 1116 to retract, so that the charging port 1117 on the charging panel 1116 is separated from the charging port on the lithium battery charging pack 8. At this time, the lithium battery charging pack 8 is fully charged and is stored in the rectangular frame 1113;

[0060] At this time, three fully charged lithium battery charging packs 8 are also arranged in the storage slot 121 arranged in the lithium battery placement device 9 in the energy storage box 7. The lithium battery charging packs 8 in the storage slot 121 are clamped by the limit plate 4 1212 driven by the hydraulic cylinder 4 1211 on the L-shaped plate 1210, and are stored in the storage slot 121. When the system in the discharge device 10 receives an external instruction to transmit energy outward, the drive guide rail 3 122 drives the drive block 3 123 to move downward, and the hydraulic cylinder 5 1213 drives the discharge panel 1214 to move upward, so that the discharge port on the lithium battery charging pack 8 is electrically connected to the discharge port 1215 on the discharge panel 1214, so that the discharge process is completed through the operation of the discharge device 10. It should be noted that because the energy supplemented to the outside needs to be calculated by the discharge device 10, when the calculated energy only needs to enable two lithium battery charging packs 8 to discharge, the remaining lithium battery charging pack 8 is still in storage state and does not perform the discharge process.

[0061] When the power of one of the three lithium battery charging packs 8 in the lithium battery placement device 9 is too low, for example, when the power of one of the two activated lithium battery charging packs 8 is too low, the discharge device 10 will activate the remaining lithium battery charging pack 8 to drive the driving block four 129 on the driving guide rail four 128 to move downward, and the hydraulic cylinder five 1213 drives the discharge panel 1214 to move upward and electrically connect with the discharge port of the lithium battery charging pack 8 through the discharge port 1215. It should be noted that the above process is applied to the situation when the lithium battery charging pack 8 is relaying during discharge operation, and the other is when the discharge is completed and the lithium battery charging pack 8 is replaced. In this case, the three lithium battery charging packs 8 are all in a placed state, and the discharge device 10 will arrange the replacement order according to the remaining power of the lithium battery charging pack 8;

[0062] The three driving guide rails 3 122 will drive the driving block 3 123 to move toward the direction of the wind and solar storage box 1, and the movement stroke of the driving guide rail 3 122 is greater than the lithium battery placement device 9. During the operation of the driving block 3 123 in the driving guide rail 3 122, the hydraulic cylinder 3 1119 in the rectangular frame 1113 will drive the limit plate 2 1120 to reset, thereby releasing the limit on the lithium battery charging pack 8 on the placement plate 1112. At this time, the placement plate 1112 on the lifting frame 1111 drives the fully charged lithium battery charging pack 8 to descend, thereby vacating the operating position for the U-shaped limit frame 118. When the placement plate 1112 on the lifting frame 1111 runs to the bottom of the U-shaped limit frame 118, the side of the lithium battery charging pack 8 is flush with the U-shaped limit frame 118. At this time, the two U-shaped limit frames 118 are on the driving guide rail 11 2 and the corresponding driving block 113 drive relative movement, when the U-shaped limit frame 118 wraps the side of the lithium battery charging pack 8, the limit plate 1110 is driven by the hydraulic cylinder 119 to contact and clamp the lithium battery charging pack 8, at this time, the lifting frame 1111 drives the placement plate 1112 to drop to the lowest height, and at this time, the driving guide rail 2 115 drives the driving block 2 116 to move toward the energy storage box 7, so that the U-shaped limit frame 118 moves into the energy storage box 7, and the driving motor 117 on the driving block 2 116 is started, driving the U-shaped limit frame 118 to flip, so that the discharge port of the lithium battery charging pack 8 faces downward. Because the U-shaped limit frame 118 is a semi-wrapped design, after flipping, the upper position of the lithium battery charging pack 8 is a clampable position and is located below the driving block three 123;

[0063] It should be noted that, because there are three drive blocks three 123, the lithium battery charging pack 8 is located under the middle drive block three 123 at this time. For example, the lithium battery charging pack 8 on the far left needs to be replaced. At this time, the drive guide rail 112 will drive the drive block 113 to move to the right, and move the lithium battery charging pack 8 to under the rightmost drive block three 123. The double-headed hydraulic cylinder 125 on the rightmost drive block three 123 drives the limit plate three 126 to clamp the front and rear sides of the lithium battery charging pack 8. At this time, the limit plate 1110 on the hydraulic cylinder 119 in the U-shaped limit frame 118 cancels the limit on the lithium battery charging pack 8, and is driven by the drive motor 117 on the drive block two 116 to rotate from a vertical state to a horizontal state, and through the drive guide rail two The driving block two 116 on 115 is retracted, and at this time the driving guide rail one 112 drives the driving block one 113 to move leftward to the position of the lithium battery charging pack 8 that needs to be replaced, and the driving block three 123 at the corresponding position moves backward, and the driving block four 129 on the driving guide rail four 128 drives the lithium battery charging pack 8 on the L-shaped plate 1210 to move upward. At this time, the lithium battery charging pack 8 is inserted sideways, and the double-headed hydraulic cylinder 125 on the corresponding driving block three 123 drives the limit plate three 126 to clamp the lithium battery charging pack 8, the hydraulic cylinder four 1211 and the upper limit plate four 1212 cancel the clamping of the lithium battery charging pack 8, and the driving guide rail three 122 drives the driving block three 123 with the lithium battery charging pack 8 to move toward the wind and solar storage box body 1, and By driving the second driving motor 124, the lithium battery charging pack 8, which was originally on the front and rear sides, is rotated to be placed on the left and right sides. At this time, the driving block 2 116 on the second driving guide rail 115 on the long board 114 moves toward the energy storage box 7, and the U-shaped limit frame 118 is adjusted to be placed vertically by the driving motor 117. At this time, the distance between the two U-shaped limit frames 118 is larger than the distance between the lithium battery charging pack 8. The driving guide rail 112 drives the driving block 113 to move relatively, and the lithium battery charging pack 8 is clamped by the upper limit plate 1110 of the hydraulic cylinder 119 in the U-shaped limit frame 118. At this time, the upper limit plate 3 126 of the double-headed hydraulic cylinder 125 cancels the limit, and drives the driving motor 2 12 through the telescopic mounting ring 15. 4 and the double-head hydraulic cylinder 125 move upward so that the limit plate three 126 does not hinder the movement of the lithium battery charging pack 8. It should be noted that the telescopic mounting ring 15 is driven by the hydraulic cylinder to be a telescopic mounting bracket, which is used to fix the drive motor two 124 and also to move the drive motor two 124. The drive motor one 117 on the drive block two 116 drives the U-shaped limit frame 118 to turn over and be placed on a plane. At this time, the drive block two 116 on the drive guide rail two 115 retracts the U-shaped limit frame 118 while the drive block one 113 on the drive guide rail one 112 drives the lithium battery charging pack 8 to move above the placement plate 1112. At this time, the lifting frame 1111 drives the placement plate 1112 to move upward and contact the lower surface of the lithium battery charging pack 8.At this time, the limiting plate 1110 in the U-shaped limiting frame 118 cancels the clamping of the lithium battery charging pack 8 under the drive of the hydraulic cylinder 119. This lithium battery charging pack 8 is a lithium battery charging pack 8 with low power. At this time, the fully charged lithium battery charging pack 8 is located on the rightmost driving block 3 123 and is clamped by the upper limiting plate 3 126 of the double-head hydraulic cylinder 125;

[0064] At this time, the lifting frame 1111 drives the placement plate 1112 to descend to the lowest position again, and the driving guide rail 112 drives the driving block 113 to move to the left. When the two U-shaped limit frames 118 are located on the left and right sides of the fully charged lithium battery charging pack 8, the sides of the lithium battery charging pack 8 are located on the left and right sides, and the driving guide rail 115 drives the driving block 2 116 to move. The driving motor 117 on the driving block 2 116 drives the U-shaped limit frame 118 to rotate. After the two U-shaped limit frames 118 are aligned with the sides of the lithium battery charging pack 8, the upper drive guide rail 112 is driven The driving block 113 moves relatively, so that the U-shaped limit frame 118 contacts the side of the lithium battery charging pack 8 and is clamped by the cooperation of the limit plate 1110 and the hydraulic cylinder 119. At this time, the driving motor 2 124 on the rightmost driving block 3 123 moves upward through the telescopic mounting ring 15, and under the drive of the driving guide rail 3 122, the driving block 3 123 is reset. At this time, the driving guide rail 112 drives the driving block 113 to move to the left, and the telescopic mounting ring 15 on the leftmost driving block 3 123 moves downward, so that the upper limit plate 3 of the double-head hydraulic cylinder 125 126 clamps the front and rear sides of the lithium battery charging pack 8. At this time, the limiting plate 1110 in the U-shaped limiting frame 118 cancels the limit on the lithium battery charging pack 8 and resets it to the wind and solar storage box 1. At this time, driven by the driving motor 2 124, the side of the lithium battery charging pack 8 is flipped to the front and rear sides, and is driven by the driving block 3 123 on the driving guide rail 3 122 to the storage slot 121, and is clamped by the limiting plate 4 1212 driven by the hydraulic cylinder 4 1211 on the L-shaped plate 1210, and the driving guide rail 4 128 drives the driving block 4 129 to move downward, and the hydraulic cylinder 5 1213 drives the discharge panel 1214 to move upward, so that the discharge port of this lithium battery charging pack 8 is electrically connected to the discharge port 1215 on the discharge panel 1214. At the same time, the placement plate 1112 on the lifting frame 1111 drives the lithium battery charging pack 8 that is out of power to move upward to the rectangular frame 1113, and is limited by the upper limit plate 2 1120 through the hydraulic cylinder 3 1119. The hydraulic cylinder 2 1118 drives the charging port 1117 on the charging panel 1116 to move and electrically connect with the charging port of the lithium battery charging pack 8 that is out of power, completing the battery replacement work.

When charging, the lithium battery charging pack is located on the placement plate, driven by the lifting frame to move upward, and moved into the rectangular frame. The hydraulic cylinder three in the rectangular frame will drive the corresponding limit plate two to contact and limit the left and right sides and the rear side of the lithium battery charging pack. The hydraulic cylinder two in the rectangular frame will drive the charging panel to move toward the lithium battery charging pack, and electrically connect the charging port on the charging panel with the charging port on the lithium battery charging pack, and introduce energy through the charging device, and transmit the energy to the charging port on the charging panel through the transformer and release it, thereby realizing the charging process for this lithium battery charging pack. When the lithium battery charging pack is fully charged, the hydraulic cylinder two will drive the charging panel to retract, so that the charging port on the charging panel is separated from the charging port on the lithium battery charging pack. At this time, the lithium battery charging pack is fully charged and is stored in the rectangular frame; At this time, three fully charged lithium battery charging packs are also arranged in the storage slot arranged in the lithium battery placement device in the energy storage box. The lithium battery charging packs in the storage slot are clamped by the limit plate four driven by the hydraulic cylinder four on the L-shaped plate and stored in the storage slot. When the system in the discharge device receives an external instruction to transmit energy outward, the drive guide rail three drives the drive block three to move downward, and the hydraulic cylinder five drives the discharge panel to move upward, so that the discharge port on the lithium battery charging pack is electrically connected with the discharge port on the discharge panel, so that the discharge process is completed through the operation of the discharge device. It should be noted that because the energy supplemented to the outside needs to be calculated by the discharge device, when the calculated energy only needs to enable two lithium battery charging packs to discharge, the remaining lithium battery charging pack is still in the storage state and does not perform the discharge process. S2: When one of the three lithium battery packs in the lithium battery placement device has a low power, for example, when one of the two activated lithium battery packs has a low power, the discharge device will activate the remaining lithium battery pack to move downward by driving the drive block four on the drive rail four, and the hydraulic cylinder five drives the discharge panel to move upward and electrically connects with the discharge port of the lithium battery pack through the discharge port. It should be noted that the above process is applied to the relay of the lithium battery pack during the discharge operation, and the other is when the discharge is completed and the lithium battery pack is replaced. In this case, the three lithium battery packs are all in the placement state, and the discharge device will arrange the replacement order according to the remaining power of the lithium battery pack; The three driving guide rails three will drive the driving block three to move toward the direction of the wind and solar storage box, and the movement stroke of the driving guide rail three is greater than the lithium battery placement device. During the operation of the driving block three in the driving guide rail three, the hydraulic cylinder three in the rectangular frame will drive the limit plate two to reset, thereby contacting the limit of the lithium battery charging pack on the placement plate. At this time, the placement plate on the lifting frame drives the fully charged lithium battery charging pack to descend, thereby vacating an operating position for the U-shaped limit frame. When the placement plate on the lifting frame runs to the bottom of the U-shaped limit frame, the side of the lithium battery charging pack is flush with the U-shaped limit frame. At this time, the two U-shaped limit frames are on the driving guide rail one and the corresponding driving block one. The U-shaped limit frame is driven to perform relative movement. When the U-shaped limit frame wraps the side of the lithium battery charging pack, the limit plate 1 is driven by the hydraulic cylinder 1 to contact and clamp the lithium battery charging pack. At this time, the lifting frame drives the placement plate to drop to the lowest height. At this time, the driving guide rail 2 drives the driving block 2 to move toward the energy storage box, so that the U-shaped limit frame moves into the energy storage box. The driving motor 1 on the driving block 2 is started, and the U-shaped limit frame is driven to flip over, so that the discharge port of the lithium battery charging pack faces downward. Because the U-shaped limit frame is a semi-wrapped design, after flipping, the upper position of the lithium battery charging pack is a clampable position and is located below the driving block 3; S3: Because there are three drive blocks three, the lithium battery charging pack is located under the middle drive block three at this time. For example, the lithium battery charging pack on the far left needs to be replaced. At this time, the drive guide rail one will drive the drive block one to move to the right, and move the lithium battery charging pack to under the rightmost drive block three. The double-headed hydraulic cylinder on the rightmost drive block three drives the limit plate three to clamp the front and rear sides of the lithium battery charging pack. At this time, the limit plate one on the hydraulic cylinder one in the U-shaped limit frame cancels the limit on the lithium battery charging pack, and is driven by the drive motor one on the drive block two to rotate from a vertical state to a horizontal state, and is retracted through the drive block two on the drive guide rail two. At this time, the drive guide rail one drives the drive The moving block 1 moves to the left and moves to the position of the lithium battery charging pack that needs to be replaced. The driving block 3 at the corresponding position moves backward, and the driving block 4 on the driving guide rail 4 drives the lithium battery charging pack on the L-shaped plate to move upward. At this time, the lithium battery charging pack is inserted and placed on the side, and the double-headed hydraulic cylinder on the corresponding driving block 3 drives the limit plate 3 to clamp the lithium battery charging pack. The limit plate 4 of the hydraulic cylinder 4 cancels the clamping of the lithium battery charging pack. The driving guide rail 3 drives the driving block 3 with the lithium battery charging pack to move toward the wind and solar storage box body, and through the drive of the driving motor 2, the lithium battery charging pack that was originally on the front and rear sides is rotated to the side and placed on the left and right sides. At this time, the long board 2 The upper drive block 2 on the upper drive guide rail 2 moves toward the energy storage box, and the U-shaped limit frame is adjusted to a vertical position through the drive motor 1. At this time, the distance between the two U-shaped limit frames is larger than the distance between the lithium battery charging packs. The drive guide rail 1 drives the drive block 1 to move relatively, and the lithium battery charging pack is clamped by the upper limit plate 1 of the hydraulic cylinder 1 in the U-shaped limit frame. At this time, the upper limit plate 3 of the double-head hydraulic cylinder cancels the limit, and drives the drive motor 2 and the double-head hydraulic cylinder to move upward through the telescopic mounting ring, so that the limit plate 3 does not hinder the movement of the lithium battery charging pack. It should be noted that the telescopic mounting ring is driven by the hydraulic cylinder as a telescopic mounting bracket, which is used to fix the drive motor 2. , and is also used to move the driving motor 2. The driving motor 1 on the driving block 2 drives the U-shaped limit frame to turn over and be placed on a flat surface. At this time, the driving block 2 on the driving guide rail 2 retracts the U-shaped limit frame, and the driving block 1 on the driving guide rail 1 drives the lithium battery charging pack to move above the placement plate. At this time, the lifting frame drives the placement plate to move upward and contact the lower surface of the lithium battery charging pack. At this time, the limit plate 1 in the U-shaped limit frame cancels the clamping of the lithium battery charging pack under the drive of the hydraulic cylinder 1. This lithium battery charging pack is a lithium battery charging pack that lacks power. At this time, the fully charged lithium battery charging pack is located on the rightmost driving block 3 and is clamped by the upper limit plate 3 of the double-head hydraulic cylinder; S4: At this time, the lifting frame drives the placement plate to drop to the lowest position again, and the driving guide rail 1 drives the driving block 1 to move to the left. When the two U-shaped limit frames are located on the left and right sides of the fully charged lithium battery charging pack, the sides of the lithium battery charging pack are located on the left and right sides, and the driving guide rail 2 drives the driving block 2 to move. The driving motor 1 on the driving block 2 drives the U-shaped limit frame to rotate. After the two U-shaped limit frames are aligned with the sides of the lithium battery charging pack, the driving guide rail 1 drives the driving block 1 to move relatively, so that the U-shaped limit frame contacts the side of the lithium battery charging pack and is clamped through the cooperation of the limiting plate 1 and the hydraulic cylinder 1. At this time, the driving motor 2 on the rightmost driving block 3 moves upward through the telescopic mounting ring, and under the drive of the driving guide rail 3, the driving block 3 is reset. At this time, the driving guide rail 1 drives the driving block 1 to move to the left, and the telescopic mounting ring on the leftmost driving block 3 moves downward, thereby making the double-headed The upper limit plate three of the hydraulic cylinder clamps the front and rear sides of the lithium battery charging pack. At this time, the limit plate one in the U-shaped limit frame cancels the limit on the lithium battery charging pack and resets it to the wind and solar storage box. At this time, driven by the drive motor two, the side of the lithium battery charging pack is flipped to the front and rear sides, and driven by the drive block three on the drive guide rail three to the storage slot, and clamped by the limit plate four driven by the hydraulic cylinder four on the L-shaped plate. The drive guide rail four drives the drive block four to move downward, and the hydraulic cylinder five drives the discharge panel to move upward, so that the discharge port of this lithium battery charging pack is electrically connected to the discharge port on the discharge panel. At the same time, the placement plate on the lifting frame drives the power-deficient lithium battery charging pack to move upward into the rectangular frame, and is limited by the upper limit plate two of the hydraulic cylinder three. The hydraulic cylinder two drives the charging port on the charging panel to move and electrically connect it to the charging port of the power-deficient lithium battery charging pack to complete the battery replacement work.
