Description

Technical Field

[0001] The invention belongs to the technical field of charging piles, and in particular relates to a DC charging pile with a ring-type bridging power distribution method. Background Art

[0002] A DC charging stack is a charging device that integrates multiple DC fast charging piles. It is usually deployed in charging stations or parking lots for fast charging of electric vehicles. Compared with a single charging pile, the charging stack can manage and allocate power resources more efficiently and meet the needs of charging multiple electric vehicles at the same time.

[0003] The ring-shaped bridging topology is a network connection method in which each node (here is the charging pile) is connected through a ring structure to form a closed loop. In this closed loop, some nodes may also use bridges (i.e. additional connections) to achieve more complex connections and communications. This structure helps to improve the reliability and redundancy of the system because even if a node or connection fails, data or power can continue to be transmitted through other paths. In this ring-shaped bridging power distribution method, the total power of the charging pile can be dynamically allocated according to the real-time needs of each charging pile. The system can monitor the charging status, battery health status, charging speed and other information of each charging pile, thereby optimizing power distribution and ensuring that each charging pile can obtain the required power. This dynamic allocation method helps to improve charging efficiency, reduce energy waste, and extend the service life of charging equipment and electric vehicle batteries.

[0004] However, the conventional device still has the following problems when used: Due to the particularity of the DC charging stack bridge power distribution method, multiple communication modules in the charging stack need to operate simultaneously to achieve ring bridging. However, the communication modules in the traditional charging stack are usually installed in parallel. When multiple communication modules are operating simultaneously, the communication module in the middle is clamped by the communication modules on both sides, and the heat dissipation efficiency will be relatively poor. When in long-term operation mode, the difference in heat dissipation efficiency between multiple modules will increase exponentially in a trapezoidal shape, which can easily affect the working status of some communication modules.

[0041] For example, see Figures 1 to 21The present invention provides a technical solution: a DC charging stack with a power distribution mode of an annular belt bridge, comprising a cabinet 1, a mounting plate 2 is fixedly connected inside the cabinet 1, a plurality of mounting racks 3 are fixedly connected to the inner wall of the mounting plate 2, a communication module 6 is movably connected to the inner wall of the mounting rack 3, a heat dissipation slot 4 connected at both ends is provided on the outer wall of the mounting rack 3, a heat dissipation channel 5 is provided between the outer walls of the plurality of mounting racks 3, a mounting mainboard 7 is provided on one side outer wall of the communication module 6, a heat dissipation cotton layer 8 is fixedly connected to the outer walls of the mounting mainboard 7 on both sides, the outer wall of the heat dissipation cotton layer 8 is movably fitted with the outer wall of the communication module 6, an extension tube 9 is buried inside the heat dissipation cotton layer 8, and a rubber extrusion port 10 is fixedly connected to the outer wall of the extension tube 9 facing the communication module 6, a temperature and humidity monitoring unit is fixedly installed inside the cabinet 1, a water tank 11 is fixedly connected to the top outer wall of the mounting mainboard 7, and the top outer wall of the water tank 11 is fixedly connected to the outer wall of the water tank 11. A bearing hinge 12 is fixedly connected, and a limit ring 13 is fixedly connected to the top outer wall of the bearing hinge 12. The water tank 11 is hinged to the limit ring 13 through the bearing hinge 12. A bending rod 14 is arranged on one side outer wall of the communication module 6. The inner wall of the limit ring 13 is movably connected to the outer wall of the bending rod 14. A rubber leak-proof port 19 connected to the inside is fixedly connected to the outer wall of one side of the water tank 11. A liquid replenishment tank 20 is fixedly connected to the outer wall of one side of the mounting frame 3. An injection port 21 is fixedly connected to the outer wall of one side of the liquid replenishment tank 20. The injection port 21 is movably connected to the rubber leak-proof port 19. An electromagnetic flow valve 24 connected to the inside is fixedly installed on the bottom outer wall of the water tank 11. The output end of the electromagnetic flow valve 24 is fixedly connected to the input end of the extension tube 9. The top outer walls of multiple liquid replenishment tanks 20 are all fixedly connected to the same liquid replenishment pipeline 23. The electromagnetic flow valve 24 is connected to the temperature and humidity monitoring unit signal.

[0042] In the present invention, a plurality of communication modules 6 are used to form an annular belt bridge to perform real-time dynamic power distribution. The communication modules 6 are movably placed by the placement frame 3, and the spacing between the communication modules 6 is ensured by the heat dissipation channel 5 to avoid multiple communication modules 6 being closely connected, maintain a certain heat dissipation space, improve the heat dissipation efficiency, and reduce the difference in heat dissipation efficiency between multiple communication modules 6. In addition, in the present invention, the interior of the water tank 11 is loaded with cooling water, and the bottom cooling water is stored in the extension pipe 9 through the electromagnetic circulation valve 24. When the heat dissipation cotton layer 8 is squeezed and fitted to the outer wall of one side of the communication module 6 When the heat dissipation is in the air, it will be relatively squeezed to the extension tube 9, so that the cooling water in the extension tube 9 is squeezed out through the rubber extrusion port 10, wetting the heat dissipation cotton layer 8, and then the heat dissipation cotton layer 8 contacts the outer wall of the communication module 6 to exchange heat with the heat transmitted during the operation of the communication module 6, thereby assisting the communication module 6 in dissipating heat, further improving and balancing the heat dissipation efficiency of the communication module 6.

At the same time, the humidity in the cabinet 1 is monitored in real time through the temperature and humidity monitoring unit to ensure that the components in the cabinet 1 are always within the humidity index. When the humidity value monitored by the temperature and humidity monitoring unit of the central control unit of the cabinet 1 is too high, the electromagnetic circulation valve 24 is closed to stop supplying cooling water, thereby waiting for the humidity value in the cabinet 1 to decrease, thereby ensuring the electrical safety in the cabinet 1.

[0051] In the present invention, after the heat dissipation cotton layer 8 squeezes the communication module 6 on one side, the installation main board 7 moves away from the heat dissipation cotton layer 8 in an oblique direction. At this time, the elastic airbag 45 is re-opened by pressing the pressing plate 46 through the expansion tension of the spring 48. At this time, the extension length of the elastic airbag 45 changes, which will drive the steel coil 58 connected to the pressing plate 46 to be pulled out from the placement box 56. At this time, the steel coil 58 will involve the movable frame 52 to rotate, and the movable frame 52 uses the meshing connection of the bevel gear three 54 and the bevel gear four 55 to synchronously drive the air blowing blade 51 to rotate, and the air blowing blade 51 is used to generate a small amount of wind flow, which is blown out through the air outlet 47 to purge the position where the heat dissipation cotton layer 8 and the communication module 6 have just been pressed, thereby accelerating the volatilization of the cooling water remaining on the outer wall of the communication module 6 and simultaneously improving the communication module 6. The heat exchange efficiency is improved, and the heat dissipation efficiency of the communication module 6 is further improved. In addition, since the installation main board 7 is moving forward in an oblique direction, it will be offset from the position just pressed. When the pressing plate 46 is separated from the surface of the communication module 6, the axis of the pressing plate 46 returns to the center, and the blowing angle of the air port 47 also rotates synchronously. This rotational movement can make the blowing direction of the air port 47 always relative to the just pressed position of the heat dissipation cotton layer 8, and continue to blow until it is completely away from the outer wall of one side of the communication module 6, further improving the heat dissipation efficiency of the communication module 6. In the present invention, one side outer wall of the rubber sheet 22 is fixedly connected to the air inlet 49 to block the air inlet 49, so that the air inlet 49 forms a one-way airflow channel, ensuring that the airflow can only pass through the air port 47 when the elastic airbag 45 is squeezed.

[0052] The working principle and use process of the present invention: In the present invention, a plurality of communication modules 6 are used to form an annular belt bridge to perform real-time dynamic power distribution, the communication module 6 is movably placed through the placement frame 3, and the spacing between each communication module 6 is ensured through the heat dissipation channel 5 to avoid multiple communication modules 6 being closely connected, maintain a certain heat dissipation space, improve the heat dissipation efficiency, and reduce the difference in heat dissipation efficiency between multiple communication modules 6. In addition, in the present invention, the interior of the water tank 11 is loaded with cooling water, and the bottom cooling water is stored in the extension tube 9 through the electromagnetic circulation valve 24. When the heat dissipation cotton layer 8 is squeezed and fitted to one side outer wall of the communication module 6, it will be relatively squeezed to the extension tube 9, so that the cooling water in the extension tube 9 is squeezed out through the rubber extrusion port 10 to wet the heat dissipation cotton layer. 8, and then the heat transfer from the communication module 6 during operation is performed through the heat dissipation cotton layer 8 contacting the outer wall of the communication module 6, thereby assisting the heat dissipation of the communication module 6, further improving and balancing the heat dissipation efficiency of the communication module 6, and the liquid replenishment pipe 23 is connected to the external water tank. When the outer wall of one side of the water tank 11 is pressed against one side of the liquid replenishment tank 20, the injection port 21 will be inserted into the rubber anti-leakage port 19 directly opposite, and water is supplied to the water tank 11 through the liquid replenishment pipe 23. In the present invention, the rubber extrusion port 10 is close to the surface of the heat dissipation cotton layer 8, but the inner cavity diameter of the extension tube 9 is extremely small, and multiple extrusions are required to make the surface of the heat dissipation cotton layer 8 reach a slightly moist state, and the electromagnetic circulation valve 24 is used to quantify the circulating cooling water to keep the water volume sufficient to soak the heat dissipation cotton layer 8 And it will not squeeze out condensed water. At the same time, the humidity in the cabinet 1 is monitored in real time through the temperature and humidity monitoring unit to ensure that the components in the cabinet 1 are always within the humidity index. When the humidity value detected by the temperature and humidity monitoring unit of the central control unit of the cabinet 1 is too high, the electromagnetic flow valve 24 will close the valve to stop supplying cooling water, thereby waiting for the humidity value in the cabinet 1 to decrease, thereby ensuring the electrical safety in the cabinet 1. In the present invention, the rotation of the reciprocating screw 25 can drive the connecting hook 18 to move back and forth, and the movement of the connecting hook 18 further drives the limit ring 13 to move back and forth, and through the limitation of the bending rod 14, the forward direction of the limit ring 13 is changed to a multi-stage reciprocating inclined movement, and drives the lower water tank 11 and the installation motherboard 7 together It makes an oblique forward movement, but through the support limit of the support bracket 61 and the hinge relationship of the bearing hinge 2 15, the direction of the water tank 11 and the installation mainboard 7 is always kept fixed when the limit ring 13 is twisted forward in an oblique direction. At this time, the oblique forward movement of the installation mainboard 7 will drive the heat dissipation cotton layers 8 on both sides to press back and forth on the outer wall of the communication module 6 in sections, thereby providing local cooling for the communication module 6 and gradually cooling the overall side wall of the communication module 6. Through this device, the communication modules 6 on both sides can be cooled simultaneously, further improving the heat dissipation efficiency of multiple communication modules 6, and through the heat generated by the continuous operation of the communication module 6, the full round-trip time of the installation mainboard 7 provides evaporation time for the trace cooling water remaining on the outer wall of the communication module 6.Thereby, the working temperature value of the communication module 6 and the spatial temperature and humidity value of the cabinet 1 are kept in relative balance. In the present invention, the refrigeration motor 38 drives the refrigeration fan blades 39 to operate, thereby providing airflow to cool the cabinet 1, and can discharge moisture, and help the cooling water remaining on the outer wall of the communication module 6 to evaporate quickly. The adjusting motor 41 drives the adjusting fan blades 42 to operate slowly, and the positive magnetic plate 43 and the negative magnetic plate 62 fixed to the adjusting fan blades 42 operate synchronously. When the cabinet door 36 and the cabinet 1 are closed, the protective cover 37 will be close to the communication module 6. At this time, the magnetic rod 34 on the same vertical plane as the communication module 6 will be magnetically attracted by the passing positive magnetic plate 43 and the negative magnetic plate 62. When the positive magnetic plate 43 passes by, the positive surface of the magnetic rod 34 will be adsorbed forward. When the pole magnetic plate 62 passes by, the magnetic rod 34 will be flipped so that the negative pole surface is attracted forward, thereby driving the magnetic rod 34 to rotate back and forth. Through the threaded connection of the bevel gear 1 30 and the bevel gear 2 31, the magnetic rod 34 drives the reciprocating screw 25 to rotate synchronously, thereby driving the connecting device under the connecting hook 18 to operate synchronously. In the present invention, the extension length of the elastic airbag 45 is higher than the extension length of the heat dissipation cotton layer 8. When the heat dissipation cotton layer 8 is pressed toward the outer wall of the communication module 6, the pressure plate 46 connected to the elastic airbag 45 will first press against the outer wall of the communication module 6, thereby squeezing the elastic airbag 45 in advance. Since the cross-section of the pressure plate 46 is an asymmetric triangular shape, when the pressure plate 46 is pressed against the outer wall of the communication module 6, the axis of the pressure plate 46 is compressed and deflected , the outer wall of the side with a longer cross-sectional length will fit against the outer wall of the communication module 6. At this time, the airflow guiding direction of the blowing port 47 will be deflected to the pre-pressed position of the heat dissipation cotton layer 8 and the communication module 6. At this time, the airflow squeezed and blown out by the elastic airbag 45 will drive the pre-pressed position of the heat dissipation cotton layer 8 and the communication module 6 to be blown in advance, thereby cleaning the dust attached to the outer wall of the communication module 6, and the communication module 6 can be pre-cooled to further improve the heat dissipation efficiency of the communication module 6. In the present invention, after the heat dissipation cotton layer 8 squeezes the communication module 6 on one side, the installation main board 7 is moved obliquely away from the heat dissipation cotton layer 8. At this time, the elastic airbag 45 is reopened by adjusting the telescopic tension of the spring 48 to press the pressing plate 46. At this time, the extension length of the elastic airbag 45 changes, which will bring The steel coil strip 58 connected to the pressure plate 46 is pulled out from the placement box 56. At this time, the steel coil strip 58 will involve the movable frame 52 to rotate. The movable frame 52 uses the meshing connection of the bevel gear three 54 and the bevel gear four 55 to synchronously drive the air blowing fan blade 51 to rotate. The air blowing fan blade 51 generates a small amount of wind, which is blown out through the air blowing port 47 to purge the heat dissipation cotton layer 8 and the position where the communication module 6 has just been pressed, thereby accelerating the volatilization of the cooling water remaining on the outer wall of the communication module 6, and simultaneously improving the heat replacement efficiency of the communication module 6, and further improving the heat dissipation efficiency of the communication module 6. In addition, since the installation main board 7 is moving forward in an oblique direction, it will be offset from the position just pressed. When the pressure plate 46 is separated from the surface pressure of the communication module 6, the axis of the pressure plate 46 returns to the center.The blowing angle of the blowing port 47 will also rotate synchronously. This rotational movement can make the blowing direction of the blowing port 47 always relative to the just pressed position of the heat dissipation cotton layer 8, and continue to blow until it is completely away from the outer wall of one side of the communication module 6, further improving the heat dissipation efficiency of the communication module 6. In the present invention, the outer wall of one side of the rubber sheet 22 is fixedly connected to the air inlet 49 to resist the air inlet 49, so that the air inlet 49 forms a one-way airflow channel, ensuring that the airflow can only pass through the blowing port 47 when the elastic airbag 45 is squeezed.
