[0027] It is easy to understand that according to the technical solution of the present invention, without changing the essential spirit of the present invention, a person skilled in the art can propose a variety of interchangeable structural modes and implementation modes. Therefore, the following specific implementation modes and drawings are only exemplary descriptions of the technical solution of the present invention, and should not be regarded as the whole of the present invention or as a limitation or restriction to the technical solution of the present invention.

[0028] A mobile energy storage device at the station side, such as Figure 1As shown, it includes an outer guard plate 3, a moving assembly 4 is provided inside the outer guard plate 3, and a container 2 is provided on the top of the moving assembly 4; the container 2 is used to store the energy storage mechanism 9, and the moving assembly 4 is used for overall movement;

[0029] The mobile assembly 4 includes a driving assembly 47 and two sets of switching rolling assemblies with the same structure; the switching rolling assembly includes a wheel 41, a connecting shaft 42, a support rod 43, a connecting rod 44, a gear 45 and a plate tooth 46; Figure 2 As shown, the driving assembly 47 cooperates with the connecting gear 45, and the driving assembly 47 is used to drive the gear 45 to rotate; the center of the gear 45 is connected to the connecting rod 44, and the end of the connecting rod 44 is connected to the connecting shaft 42; both ends of the connecting shaft 42 are connected to the wheels 41; the side of the gear 45 engages with the plate tooth 46, and the plate tooth 46 is fixed to the side of the support rod 43; when the gear 45 drives the wheel 41 to rotate, it can drive the support rod 43 to rise and fall, and switch the moving state of the wheel 41 and the supporting state of the support rod 43.

[0030] Exemplarily, preferably, the driving assembly 47 includes a mounting plate 471, a bidirectional synchronous telescopic electric push rod 472, a moving plate 473 and a plate tooth 2 474; the mounting plate 471 is mounted inside the outer support plate 3, and a bidirectional synchronous telescopic electric push rod 472 is provided on the side of the mounting plate 471; two moving plates 473 are connected to the two sides of the bidirectional synchronous telescopic electric push rod 472, and a plate tooth 2 474 is provided at the bottom end of each moving plate 473; the two plate teeth 2 474 are respectively connected to the two switching rolling assemblies. The driving assembly 47 can also be a combination of a pneumatic guide rail and a pneumatic slider, the pneumatic slider is connected to the moving plate 473, and the pneumatic slider is used to move on the pneumatic guide rail, thereby driving the moving plate 473 and the plate tooth 2 474 on the side to move.

[0031] In order to make the sliding of the movable plate 473 more stable, a limiting groove 34 is provided inside the outer supporting plate 3, and the movable plate 473 is adapted to and slidably connected with the limiting groove 34.

[0032] In order to make the lifting and lowering of the support rod 43 more stable, a sliding groove 32 is opened on the side of the outer guard support plate 3, and the cross-section of the support rod 43 is a "7"-shaped structure; the support rod 43 is slidably connected to the sliding groove 32; a through hole 31 is opened on the side of the outer guard support plate 3, and the through hole 31 cooperates to connect the movable plate 473 and the plate tooth 2 474.

[0033] After the entire energy storage device reaches the appropriate position, the support rod 43 is used to support the wheel 41 instead of the wheel 41, so that the wheel 41 is folded and stored. During operation, the two-way synchronous telescopic electric push rod 472 is started. When the two-way synchronous telescopic electric push rod 472 is started, it pushes the two moving plates 473 away from each other. When the two moving plates 473 move away from each other, the plate tooth 2 474 at the bottom of the moving plate 473 drives the gear 45 meshing therewith to rotate counterclockwise. When the gear 45 rotates counterclockwise, it drives the two wheels 41 to rotate toward the outer guard plate 3 through the connecting rod 44 and the connecting shaft 42. Another switching rolling component rotates synchronously in the outer guard plate 3 under the drive of the driving component 47, so that the four wheels 41 are folded. In addition, when the gear 45 rotates counterclockwise, it can mesh with the plate tooth 1 46, and drive the support rod 43 to move downward through the plate tooth 1 46, so that when the wheel 41 rotates toward the outer guard plate 3, it can synchronously drive the support rod 43 to move downward to support the entire energy storage device.

[0034] The energy storage device of the present invention has a wheel 41 at the bottom end connected to a support rod 43 by a gear 45 and a plate tooth. When the energy storage device moves, the wheel 41 contacts the ground. At this time, the wheel 41 can be used to move the entire energy storage device. When the energy storage device is not moving, in order to protect the wheel 41, the drive assembly 47 is used to drive the wheel 41 to rotate and the support rod 43 is used to support it when it is retracted, ensuring that the energy storage device can be stably placed and has no effect on the next movement; the energy storage mechanism 9 can immediately release the stored electrical energy to increase the voltage level of the local power grid; therefore, the energy storage device of the present invention is easy to move, can quickly reach a short-term low-voltage area to work, can be stably placed when not moving, and has a long service life.

[0035] In order to enhance the ventilation effect inside the container 2 and enhance the heat dissipation of the energy storage mechanism 9, a semicircular ventilation hole 33 is provided at the top of the outer supporting plate 3, and an isolation net 8 is provided at the bottom of the container 2; the energy storage mechanism 9 is placed on the surface of the isolation net 8, and the air entering through the ventilation hole 33 provided at the top of the outer supporting plate 3 can dissipate the heat of the energy storage mechanism 9 through the isolation net 8, thereby enhancing the cooling effect of the energy storage mechanism 9 and extending its service life.

[0036] In order to enhance the air circulation inside the container 2 and the heat dissipation effect, heat dissipation holes 21 are provided on the top of both sides of the container 2, and insect-proof nets 22 are installed in the heat dissipation holes 21; a protective cover plate 1 is provided on the top of the container 2, and the protective cover plate 1 is connected to the heat dissipation holes 21. Figure 3 and Figure 4 shown.

[0037] A lifting assembly 7 is provided between the protective cover plate 1 and the isolation net 8, and the lifting assembly 7 includes an extension rod 71, a movable rod 72, a limit rod 73, a roller 74, a thermal expansion and contraction block 75 and a heat-conducting outer sleeve 76; Figure 5 As shown, the interior of the heat-conducting outer sleeve 76 is provided with a thermal expansion and contraction block 75, the volume of the thermal expansion and contraction block 75 expands when the temperature rises, and the volume shrinks when the temperature drops, and the thermal expansion and contraction block 75 includes a shape memory alloy, exemplarily a nickel-titanium alloy; and the top of the thermal expansion and contraction block 75 contacts the limit rod 73; rollers 74 are provided on both sides of the limit rod 73, and a movable rod 72 is fixed to the top of the limit rod 73; the top of the movable rod 72 is connected to the protective cover plate 1, and the side of the movable rod 72 is provided with an extension rod 71; the extension rod 71 cooperates with the fire extinguishing assembly 6. Specifically, the fire extinguishing assembly 6 includes a container 61, a nozzle 62 and a pressure handle 63; the container 61 is used to contain dry powder fire extinguishing agent, and the side of the container 61 is installed with a nozzle 62; the side of the nozzle 62 is provided with a pressure handle 63, and the pressure handle 63 is used to open the nozzle 62. Therefore, when the internal temperature of the container 2 continues to rise due to seasonal reasons, the volume of the thermal expansion and contraction block 75 increases, pushing the limit rod 73 to drive the movable rod 72 to move upward under the drive of the roller 74, and using the driving force of the expansion of the thermal expansion and contraction block 75 to push the protective cover plate 1 upward to expose the heat dissipation hole 21, so that a flow channel is formed between the heat dissipation hole 21 and the isolation net 8 to ensure that external air enters and can fully dissipate heat in the container 2. If a fire occurs in the container 2, as the expansion force of the thermal expansion and contraction block 75 continues to increase, even ventilation cannot reduce the internal temperature, the movable rod 72 continues to move upward under the continued push of the thermal expansion and contraction block 75, so that the extended rod 71 pushes the pressure handle 63, and at this time the nozzle 62 is opened, and the dry powder fire extinguishing agent in the container 61 is used to extinguish the fire.

[0038] When the energy storage device of the present invention is in use, it can push the protective cover plate 1 upward according to the principle of thermal expansion and contraction as the temperature rises, thereby exposing the heat dissipation holes 21, increasing the air flow inside the container 2, and improving the internal heat dissipation and cooling effects; extending the service life of the energy storage mechanism 9; when a fire occurs inside, the nozzle 62 of the dry powder fire extinguisher can be opened according to the higher temperature to extinguish the fire with the dry powder fire extinguisher, thereby avoiding greater economic losses.

[0039] The container 2 of the device of the present invention can be equipped with a temperature sensor and a smoke sensor, which cooperate with a controller and a signal transmitter to send the internal environmental conditions to the terminal so that the terminal can understand the internal conditions of the container 2 in time.

[0040] In order to facilitate the connection of the entire device with the external drive device, a connector 5 is fixed to the side of the outer support plate 3, and a connecting hole is provided on the side of the connector 5. The connector 5 is used to connect with the external drive device to move the entire energy storage device.

[0041] The energy storage mechanism 9 includes a communication control system, an energy management system, a battery system, a bidirectional inverter, a transformer, an on-grid and off-grid switching system, a battery management module and an energy storage battery pack; Figure 6 As shown, the communication control system is connected to the energy management system, the energy management system is connected to the battery system and the bidirectional inverter; the battery system is connected to the energy storage battery pack and the battery management module; the bidirectional inverter is connected to the transformer and the on-grid and off-grid switching system.

[0042] When the present invention is in use, first, when moving, an external drive device is used to connect with the connector 5, and the external drive device is used to pull the entire energy storage device to a short-term low-voltage position. The energy storage system can immediately release the stored electrical energy to improve the voltage level of the local power grid. When reaching a suitable position, first, the support rod 43 is used to replace the wheel 41 for support, and the wheel 41 is retracted for storage and protection. During operation, the two-way synchronous telescopic electric push rod 472 is started. When the two-way synchronous telescopic electric push rod 472 is started, it pushes the two moving plates 473 away from each other. When the two moving plates 473 move away from each other, the plate tooth 474 at the bottom of the moving plate 473 drives the gear 45 meshing therewith to rotate counterclockwise. When the gear 45 rotates counterclockwise, the two wheels 41 are driven to rotate toward the inner side of the outer guard plate 3 through the connecting rod 44 and the connecting shaft 42, and the other cuts The rolling assembly rotates synchronously inside the outer guard plate 3 under the drive of the driving assembly 47, so that the four wheels 41 are retracted. In addition, the gear 45 can mesh with the plate tooth 46 when rotating counterclockwise, and drive the support rod 43 to move downward through the plate tooth 46, so that when the wheel 41 rotates toward the outer guard plate 3, the support rod 43 can be synchronously driven to move downward to support the entire energy storage device; when the energy storage mechanism 9 is in use, if it is summer, the internal temperature rises, the volume of the thermal expansion and contraction block 75 increases, and the limit rod 73 is pushed to drive the movable rod 72 to move upward under the drive of the roller 74, and the driving force of the expansion of the thermal expansion and contraction block 75 is used to push the protective cover plate 1 to move upward, so that the heat dissipation hole 21 is exposed, and a flow channel is formed between the heat dissipation hole 21 and the isolation net 8, ensuring that external air enters, so that comprehensive heat dissipation in the container 2 can be achieved. If a fire or explosion occurs in the container 2, as the expansion force of the thermal expansion and contraction block 75 continues to increase, even ventilation cannot reduce the internal temperature. The movable rod 72 continues to move upward under the continued push of the thermal expansion and contraction block 75, so that the extended rod 71 pushes the pressure handle 63. At this time, the nozzle 62 is opened, and the dry powder fire extinguishing agent in the container 61 is used to extinguish the fire.
