Description

Technical Field

[0001] This invention relates to the field of photovoltaic energy storage charging pile technology, specifically a power supply control method and system for photovoltaic energy storage charging piles. Background Technology

[0002] A photovoltaic energy storage charging pile is an intelligent system that integrates photovoltaic power generation, energy storage batteries, and electric vehicle charging functions. Its basic working process is that solar panels convert sunlight into direct current, which the system will prioritize using to charge the car. When there is a surplus of power generation, the excess energy will be automatically stored in the energy storage battery. When the power generation is insufficient, the system will use the energy stored in the battery to supplement it. If the battery power is also insufficient, the system will automatically switch to grid power supply to ensure uninterrupted charging. This system can effectively reduce charging costs and mitigate the impact of high-power charging on the power grid through its self-consumption and peak shaving and valley filling operation mode.

[0003] Currently, the existing photovoltaic energy storage charging piles' energy storage battery systems, due to their centralized air supply for heat dissipation, can only supply air from a designated direction. Furthermore, the fixed installation of the energy storage battery system allows for battery disassembly and separation, preventing the existing photovoltaic energy storage charging piles from achieving uniform internal heat dissipation and flexible outer casing removal during operation. Therefore, an improved device is needed to address these issues. Summary of the Invention

The positioning component includes a synchronization device and a contact component. The synchronization device is slidably installed on both sides of the contact component. The synchronization device includes a protective side cover, a first transmission rack, a filter screen, an L-shaped connecting plate, a return spring, a positioning rod, and a connecting vertical rod. The system comprises a rod, a connecting cavity, a synchronizing rod, and a displacement washer. The filter screen is fixedly installed inside both sides of the protective side cover.

The L-shaped connecting plate is symmetrically fixedly installed at the bottom of the side end of the protective side cover. The connecting cavity is fixedly installed at the top of the L-shaped connecting plate. The return spring is fixedly installed at the top of the inside of the connecting cavity. The positioning rod slides through the bottom end of the L-shaped connecting plate and the connecting cavity and connects to the bottom end of the return spring. The connecting vertical rod slides through the top end of the connecting cavity and connects to the positioning rod. The synchronizing rod is fixedly installed between the two connecting vertical rods.

[0006] Specifically, the contact component includes an alignment device and a support device, wherein the alignment device is symmetrically slidably inserted into both sides of the inside of the support device.

[0007] Specifically, the alignment device includes a shaped bracket, a supporting crossbeam, a cooling fan, an extension arm, a first transmission gear, a nylon brush, and a second transmission rack. The shaped bracket is fixedly installed at the top of the second transmission rack, the supporting crossbeam is fixedly installed at the bottom of the shaped bracket, the cooling fan is fixedly installed at equal intervals at the side ends of the supporting crossbeam, the extension arm is symmetrically fixedly installed at the side ends of the supporting crossbeam near the cooling fan, the first transmission gear is rotatably installed at the side end of the extension arm, and the nylon brush is fixedly installed at the center of the side end of the first transmission gear.

[0008] Specifically, the support device includes a second transmission gear, a transmission screw, a drive motor, a guide base, guide vertical rods, an energy storage battery, a protective shell, and a partition back plate. The partition back plate is symmetrically and fixedly installed inside the protective shell. The energy storage battery is placed and installed at the top of the partition back plate. The second transmission gear is rotatably installed at the rear end of the partition back plate. The drive motor is fixedly installed at the bottom inside the protective shell. The transmission screw is fixedly installed at the center of the bottom end of the drive motor. The guide vertical rods are symmetrically and fixedly installed at the bottom inside the protective shell, and the guide vertical rods are located on both sides of the energy storage battery. The guide base is symmetrically and fixedly installed at the bottom ends of both sides of the protective shell.

[0009] Specifically, the protective side cover is slidably inserted into both sides of the protective shell, the supporting crossbar is slidably sleeved on the outer ring of the guide vertical rod, the first transmission gear meshes with the first transmission rack, and the second transmission rack meshes with the second transmission gear.

[0010] Specifically, the protective back cover is fixedly installed at the rear end of the protective shell, a key is fixedly installed at the bottom end of the L-shaped connecting plate, and a slot is opened at the top end of the guide frame. The side end of the nylon brush away from the first transmission gear is in contact with the side end surface of the filter screen near the first transmission rack.

[0011] Specifically, the protective shell has square holes on both sides, the connecting cavity is hollow, the outer surface of the displacement pad is in contact with the inner wall of the connecting cavity, and the guide base has round holes inside.

[0012] A method for a power supply control system for a photovoltaic energy storage charging pile, comprising the following steps: S1. First, when the photosensitive photovoltaic panel receives sunlight, it converts light energy into electrical energy. When the power generation of the photosensitive photovoltaic panel is sufficient, the control cabinet will directly supply the DC power converted from solar energy to the car through the charging pile, thereby providing energy for the car. S2. After that, when the support device is running, a lot of high temperature will be generated. The cooling fan and drive motor can be turned on simultaneously, so that the second transmission rack can move up and down along the surface of the second transmission gear. At this time, the cooling fan can spray airflow onto the energy storage battery, so that the energy storage battery can be cooled. At the same time, the cooling fans on both sides are staggered up and down, which facilitates uniform cooling of the energy storage battery. S3. Finally, when the synchronous rod is pulled upward, the positioning rod can be pulled out from the inside of the guide frame, which can release the protective side cover. Then, the protective side cover can be pulled away from the protective shell, making it easy for the user to remove the energy storage battery from the inside of the protective shell.

[0013] The beneficial effects of this invention are: First, this invention utilizes a drive motor to rotate a transmission screw during operation. A second transmission rack at one end is threaded onto the outer ring of the transmission screw, causing the transmission screw to rotate and move the second transmission rack up and down. Simultaneously, the second transmission rack at one end meshes with a second transmission gear, allowing the second transmission rack at the other end to move synchronously as it moves. This enables the cooling fan to move up and down along the surface of the energy storage battery inside the protective casing, evenly spraying airflow onto the surface of the energy storage battery. Furthermore, when the support crossbeam moves, it drives the first transmission gear to move along the first transmission rack, allowing the nylon brush to remove impurities adhering to the inside of the filter screen, thus achieving uniform heat dissipation.

[0014] Second, the present invention allows the protective side cover to slide inside the top of the guide frame via a key at the bottom of the L-shaped connecting plate, enabling it to move in a straight line and separate from the protective shell. Simultaneously, when the synchronous rod is pulled upward, the positioning rod can be pulled out from inside the guide frame, facilitating the placement of the protective side cover. Furthermore, the elasticity of the return spring causes the positioning rod to insert into the guide frame, thus restricting the protective side cover to the top of the guide frame. This facilitates the movement and insertion of the protective side cover into the two sides of the protective shell, completing the flexible disassembly of the protective side cover.

[0019] The invention will be further described below with reference to the accompanying drawings.

[0020] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the present invention discloses a power supply control method and system for a photovoltaic energy storage charging pile, comprising a photosensitive photovoltaic panel 5, a charging pile 4 fixedly installed at the bottom end of the photosensitive photovoltaic panel 5, a positioning component 1 fixedly installed at the rear end of the charging pile 4, a protective rear cover 2 fixedly installed at the rear end of the positioning component 1, and a control cabinet 3 fixedly installed at the bottom end of the positioning component 1.

[0022] like Figure 7 The alignment device 18 includes a shaped bracket 20, a support crossbeam 21, a cooling fan 22, an extension arm 23, a first transmission gear 24, a nylon brush 25, and a second transmission rack 26. The shaped bracket 20 is fixedly installed at the top of the second transmission rack 26, the support crossbeam 21 is fixedly installed at the bottom of the shaped bracket 20, the cooling fan 22 is fixedly installed at equal intervals on the side ends of the support crossbeam 21, and the extension arm 23 is symmetrically fixedly installed on the side ends of the support crossbeam 21 near the cooling fan 22. The first transmission gear 24 rotates. Installed on the side end of the extension arm 23, the nylon brush 25 is fixedly installed at the center of the side end of the first transmission gear 24. The nylon brush 25 adheres to the inner wall of the filter screen 10, so that the impurities attached to the inner wall of the filter screen 10 can be removed. It is installed between the second transmission rack 26 and the support cross frame 21 through the special bracket 20, so that the second transmission rack 26 can be connected to the support cross frame 21 by passing around the energy storage battery 32. Thus, when the second transmission rack 26 is displaced, it can drive the support cross frame 21 to move up and down.

[0023] like Figure 8The support device 19 includes a second transmission gear 27, a transmission screw 28, a drive motor 29, a guide base 30, a guide vertical rod 31, an energy storage battery 32, a protective shell 33, and a partition back plate 34. The partition back plate 34 is symmetrically fixedly installed inside the protective shell 33. The energy storage battery 32 is placed on the top of the partition back plate 34. The second transmission gear 27 is rotatably installed at the rear end of the partition back plate 34. The drive motor 29 is fixedly installed at the bottom inside the protective shell 33. The transmission screw 28 is fixedly installed at the center of the bottom end of the drive motor 29. The guide vertical rod 31 is symmetrically fixedly installed at the bottom inside the protective shell 33, and the guide vertical rod 31 is located on both sides of the energy storage battery 32. The guide base 30 is symmetrically fixedly installed at the bottom ends on both sides of the protective shell 33. By setting the partition back plate 34, the energy storage battery 32 can be divided into two independent areas, so as to avoid the convection phenomenon when the airflow flows on the surface of the energy storage battery 32.

[0024] The protective side cover 8 is slidably inserted into both sides of the protective shell 33. The supporting crossbar 21 is slidably sleeved on the outer ring of the guide vertical rod 31.

The side end of the nylon brush 25 away from the first transmission gear 24 is attached to the side end surface of the filter screen 10 near the first transmission rack 9. Square holes are opened on both sides of the protective shell 33. The interior of the connecting cavity 15 is hollow, and the outer surface of the displacement pad 17 is attached to the inner wall of the connecting cavity 15. A round hole is opened inside the guide base 30.

[0025] A method for a power supply control system for a photovoltaic energy storage charging pile, comprising the following steps: S1. First, when the photosensitive photovoltaic panel 5 receives sunlight, it converts light energy into electrical energy. When the power generation of the photosensitive photovoltaic panel 5 is sufficient, the control cabinet 3 will directly supply the DC power converted from solar energy to the car through the charging pile 4, thereby providing energy for the car. S2. Afterwards, when the support device 19 is running, it will generate a lot of high temperature. The cooling fan 22 and the drive motor 29 can be turned on and run synchronously, so that the second transmission rack 26 can move up and down along the surface of the second transmission gear 27. At this time, the cooling fan 22 can spray airflow onto the energy storage battery 32, so that the energy storage battery 32 can be cooled. At the same time, the cooling fans 22 on both sides are staggered to facilitate uniform cooling of the energy storage battery 32. S3. Finally, when the synchronous rod 16 is pulled upward, the positioning rod 13 can be pulled out from the inside of the guide base 30, and the protective side cover 8 can be released. Then, the protective side cover 8 can be pulled away from the protective shell 33, so that the user can easily take out the energy storage battery 32 from the inside of the protective shell 33.

[0026] The working principle is as follows: During use, the photovoltaic panel 5 is connected to the control cabinet 3, allowing the control cabinet 3 to transfer the electrical energy generated by the photovoltaic panel 5 to the internal storage of the energy storage battery 32. Simultaneously, the energy storage battery 32 is connected to the charging pile 4, allowing the vehicle to replenish its electrical energy through the charging pile 4. At the same time, when the energy storage battery 32 is running, the cooling fan 22 and the drive motor 29 are turned on synchronously. When the drive motor 29 is turned on, it drives the transmission screw 28 to rotate. A connecting plate is fixedly installed at the bottom of a second transmission rack 26, and the connecting plate is threaded onto the outer ring of the transmission screw 28. When the transmission screw 28 rotates, it drives the second transmission rack 26 to move downwards. The second transmission rack 26 then... The two transmission gears 27 mesh, so that when one second transmission rack 26 moves downward, it can drive the other second transmission rack 26 to move upward. When the second transmission rack 26 is displaced, it can drive the cooling fan 22 to move along the side of the energy storage battery 32, so that the cooling fan 22 can spray air evenly onto the surface of the energy storage battery 32. The protective back cover 2 can exhaust hot air, and the filter screen 10 can allow the cooling fan 22 to absorb outside air. When the second transmission rack 26 is displaced, it can drive the first transmission gear 24 to move along the first transmission rack 9 through the special bracket 20, so that the first transmission gear 24 can drive the nylon brush 25 to rotate. The nylon brush 25 moves away from the first transmission rack 9. The side end of the moving gear 24 is in contact with the inner wall of the filter screen 10, so that when the nylon brush 25 rotates, it can remove the impurities attached to the inner wall of the filter screen 10. The support crossbar 21 is slidably sleeved on the outer ring of the guide vertical rod 31, so that the support crossbar 21 can be supported to move up and down in a straight line. When the protective side cover 8 needs to be removed during use, the synchronous rod 16 can be moved upward and pulled, so that the positioning rod 13 can be pulled out from the inside of the guide base 30, and the L-shaped connecting plate 11 can be released. At this time, the protective side cover 8 can be pulled away from the end away from the energy storage battery 32. The locking key at the bottom of the L-shaped connecting plate 11 slides in the locking groove inside the top of the guide base 30, so that the protective side cover 8 can be supported to move in a straight line until the protective side cover 8 and the protective shell 33 are aligned. The protective side cover 8 can be disassembled to facilitate the inspection or operation of the energy storage battery 32. After the energy storage battery 32 has been inspected, the synchronizing rod 16 can be pulled upwards again until the bottom end of the positioning rod 13 is higher than the top end of the guide base 30. Then, the locking key at the bottom end of the L-shaped connecting plate 11 is slidably inserted into the slot inside the top end of the guide base 30, so that the protective side cover 8 moves in a straight line to align with the energy storage battery 32. When the protective side cover 8 moves to fit against the side end of the energy storage battery 32, the positioning rod 13 can be vertically aligned with the insertion hole inside the guide base 30. The synchronizing rod 16 can then be released. The elasticity of the return spring 12 will cause the displacement pad 17 to move downwards quickly, so that the positioning rod 13 can be inserted into the insertion hole inside the guide base 30.The protective side cover 8 can be fixed to the side of the energy storage battery 32, making it easy for the protective side cover 8 to be positioned on both sides of the energy storage battery 32 for protection. During use, two partition back plates 34 are provided inside the protective shell 33, and the partition back plates 34 are attached to the energy storage battery 32, allowing the energy storage battery 32 to be divided into two parts for separate cooling, preventing air convection from the cooling fans 22 in two directions. Furthermore, heat dissipation holes are equidistantly provided inside the protective back cover 2, facilitating the exhaust of hot air. Square holes are provided on both sides of the protective shell 33, allowing the protective side cover 8 to be moved to the protective shell. The shell 33 is fitted together, and the drive motor 29 turns the transmission screw 28 forward and backward, allowing the two second transmission racks 26 to move up and down inside the protective shell 33. This allows the cooling fan 22 to evenly dissipate heat from the surface of the energy storage battery 32. Simultaneously, the support crossbeam 21, by moving up and down, drives the first transmission gear 24 to move along the first transmission rack 9, which in turn drives the nylon brush 25 to rotate, cleaning the filter screen 10. The up-and-down movement of the support crossbeam 21 also allows the nylon brush 25 to remove impurities at different heights from the filter screen 10, improving the smoothness of airflow through the filter screen 10 and completing the operation.
