This grid-type energy storage converter includes a housing, with a transformer fixedly installed on the side of the inner wall of the housing, a battery fixedly installed at the bottom of the inner cavity, and a mounting plate fixedly connected to the front of the inner wall of the housing. This utility model provides an energy storage converter based on grid-type energy storage, which, by incorporating a battery, allows the transformer to convert high-voltage current into low-voltage direct current when supplying power to a load, and then transmit this power to the battery for storage, enabling the battery to convert electrical energy into chemical energy for storage.

[0004] In existing technology, a rotary motor is started, which drives the fan blades to rotate rapidly, thereby facilitating rapid air exchange between the inside and outside of the chamber and increasing the rate of heat dissipation. However, no corresponding equipment is provided to treat the filter screen, and there is no way to control the opening and closing of the air inlet and outlet on the chamber during heat exchange. Summary of the Invention

[0005] Therefore, the present invention provides a grid-type energy storage converter to solve the above-mentioned technical problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a grid-type energy storage converter, comprising a housing, a door hinged to the front end of the housing, and multiple sets of support feet fixedly connected to the bottom of the housing; an output port is provided on the side wall of the housing, and an opening assembly is provided on the left and right side walls of the housing; a partition is fixedly connected to the lower end of the housing, and a battery is provided on the partition; a transformer, a supercapacitor, and a step-up transformer are provided on the side wall of the housing; a guide fan is connected to the air outlet of the housing; the rotating shaft of the guide fan is fixedly connected to a drive shaft, the other end of the drive shaft is fixedly connected to an upper pulley, the end of the drive shaft is fixedly coaxially connected to a disc, a first connecting rod is rotatably connected to the side wall of the disc, the other end of the first connecting rod is rotatably connected to a second connecting rod, a connecting plate is fixedly connected to the inner side wall of the housing, a magnetic cutting plate is slidably connected to the connecting plate, and the magnetic cutting plate is fixedly connected to the second connecting rod.

[0007] Preferably, the magnetic cutting plate is fixedly connected to the transmission rod, the other end of the transmission rod is fixedly connected to the insertion rod, and a filter screen is embedded in the side wall of the box.

[0008] Preferably, an insertion rod is provided in front of the filter screen, a cleaning rod is slidably connected to the insertion rod, a return spring is fixedly connected to the side wall of the cleaning rod, and the other end of the return spring is fixedly connected to the insertion rod.

[0009] Preferably, multiple sets of protrusions are fixedly connected to the side wall of the box directly above the cleaning rod.

[0011] Preferably, the lower pulley is fixedly connected to the guide shaft, the guide shaft is fixedly connected to the receiving wheel coaxially, and the receiving wheel is rotatably connected to the circular groove.

[0012] Preferably, the upper end of the circular groove is connected to the area below the filter screen, and the bottom area of ​​the circular groove is provided with a discharge port.

[0013] Preferably, the cable connecting the transformer and the battery is wound around the magnetic cutting plate to form a coil, and the magnetic field generated on the coil cuts the magnetic cutting plate. The magnetic cutting plate is connected to the electromagnetic spring through the cable.

[0015] Preferably, multiple sets of stirring blades are fixedly connected to the side wall of the guide shaft.

[0016] The beneficial effects of this invention are as follows: This invention uses a guide fan to drive the linkage, causing the cleaning rod to move back and forth, and the top of the rod to press against the protrusion during the movement. This achieves both left and right movement and up and down sliding, which improves the cleaning effect on the filter screen surface, ensures unobstructed heat dissipation channels, and facilitates heat dissipation of the equipment. The cleaning rate of the filter screen and the opening and closing of the air inlet and outlet of the housing are controlled by the operating speed of the guide fan.

[0017] This invention uses a drive shaft to rotate the upper and lower pulleys, which in turn rotate the receiving wheel. This causes impurities falling from above to reach the receiving wheel and rotate downwards to the discharge port area, facilitating subsequent recovery of the impurities and keeping the inside of the equipment clean.

[0018] This invention uses a magnetic cutting plate to cut magnetic lines of force, which energizes an electromagnetic spring and causes the inner plate to move so that it overlaps with the air guide holes on the outer frame, allowing external air to enter the enclosure. When the magnetic cutting plate stops, the electromagnetic spring is de-energized, causing the inner plate to move and reset, and the air guide holes are staggered, resulting in a closed enclosure. This allows for flexible control of ventilation based on the equipment's operating conditions. Attached Figure Description

Detailed Implementation

[0021] To further explain the technical solution of the present invention, a detailed description is provided below through specific embodiments.

[0022] As shown in Figure 1, the present invention provides a grid-type energy storage converter, including a housing 1, a door 2 hinged to the front end of the housing 1, and multiple sets of support legs 3 fixedly connected to the bottom of the housing 1; an output port 4 is provided on the side wall of the housing 1, and an opening assembly 5 is provided on the left and right side walls of the housing 1; a partition 6 is fixedly connected to the lower end of the housing 1, and a battery 7 is provided on the partition 6; a transformer 9, a supercapacitor 10, and a booster 11 are provided on the side wall of the housing 1.

[0023] As shown in Figures 1 to 4, the input terminal of the storage battery 7 is electrically connected to the output terminal of the transformer 9. By installing the storage battery 7, when power is supplied to a load, the transformer 9 converts the high-voltage current into low-voltage DC current, which is then delivered to the storage battery 7 for storage. This allows the storage battery 7 to convert electrical energy into chemical energy for storage. Consequently, when a grid fault causes the input current to the transformer 9 to disconnect, the storage battery 7 can continuously supply current to the supercapacitor 10, achieving long-term continuous discharge of the supercapacitor 10. This avoids the problem of short operating time and difficulty in achieving emergency power supply when the capacitor operates alone, thus improving the efficiency of the converter. Practical effects: The input terminal of the supercapacitor 10 is electrically connected to the output terminal of the battery 7, and there are several supercapacitors 10. By setting up the supercapacitors 10, when continuously supplying power to the load, the supercapacitors 10 greatly improve the stability of the output current and voltage, thereby avoiding the problem of electrical appliance failure caused by rapid current disconnection and closure, thus improving the stability of the current output. The input terminal of the boost converter 11 is electrically connected to the output terminal of the battery 7. When the current input is overloaded, the output terminal of the boost converter 11 is connected to the power grid. At this time, the boost converter 11 can boost and convert the output current of the battery 7, and then transmit it. This allows for continuous current utilization within the power grid, avoiding energy waste caused by low converter output power and thus improving energy conservation. Firstly, when supplying power to a load, transformer 9 converts high-voltage current into low-voltage DC current, which is then delivered to battery 7 for storage. Battery 7 converts electrical energy into chemical energy for storage. Therefore, even when a grid fault causes the input current to transformer 9 to disconnect, battery 7 continues to supply current to supercapacitor 10, enabling long-term continuous discharge of supercapacitor 10. This avoids the problem of short operating times and difficulty in discharging when capacitors operate alone. This achieves emergency power supply, thereby improving the practical effect of the converter. When continuously supplying power to the load, the supercapacitor 10 greatly improves the stability of the output current and voltage, thus avoiding the problem of electrical appliance failure caused by rapid current disconnection and closure, thereby improving the stability of current output. When the current input is overloaded, the output terminal of the boost converter 11 is connected to the inside of the power grid. At this time, the boost converter 11 can boost and convert the output current of the battery 7 and then send it to the inside of the power grid, thereby achieving the effect of continuous current utilization. This avoids the problem of energy waste caused by the low output power of the converter, thereby improving the energy saving effect.

[0024] Please refer to Figures 1 to 8. A guide fan 8 is connected to the air outlet of the housing 1. When the system is powered on, the control unit starts the guide fan 8, which rotates, generating a forced airflow from inside the housing 1 to the outside, thus achieving basic heat dissipation for the power devices inside the housing 1. The guide fan 8 is used to drive the airflow to dissipate heat inside the housing 1. The rotating shaft of the guide fan 8 is fixedly connected to the drive shaft 81, and the guide fan 8 drives the drive shaft 81 to rotate, providing power for the operation of the drive shaft 81. The other end of the drive shaft 81 is fixedly connected to the upper pulley 82, and the drive shaft 81 can drive the upper pulley while rotating. 82 rotates, and the end of the drive shaft 81 is coaxially and fixedly connected to the disk 83, providing power for the rotation of the disk 83. A first connecting rod 84 is rotatably connected to the side wall of the disk 83, and the other end of the first connecting rod 84 is rotatably connected to the second connecting rod 85. When the disk 83 rotates, it drives the first connecting rod 84 to move, and the first connecting rod 84 transmits thrust to the second connecting rod 85. The second connecting rod 85 can also drive the magnetic cutting plate 87 to move. A connecting plate 86 is fixedly connected to the inner side wall of the housing 1, providing power for the magnetic cutting plate 87. The magnetic cutting plate 87 is slidably connected to the connecting plate 86, and the magnetic cutting plate 87 is connected to the second connecting rod 85. Link 85 is fixedly connected, so that when the magnetic cutting plate 87 moves, it simultaneously drives the second link 85 to move; the disk 83 rotates, causing the first link 84, which is eccentrically connected to it, to perform planar motion. The first link 84 transmits the motion to the second link 85, which then converts this motion into horizontal reciprocating linear motion of the magnetic cutting plate 87 on the guide rail of the connecting plate 86; wherein, the magnetic cutting plate 87 is fixedly connected to the transmission rod 88, and the other end of the transmission rod 88 is fixedly connected to the insertion rod 89. A filter screen 810 is embedded in the side wall of the housing 1, and an insertion rod is provided in front of the filter screen 810. A cleaning rod 811 is slidably connected to the insertion rod 89. A return spring 812 is fixedly connected to the side wall of the cleaning rod 811. The other end of the return spring 812 is fixedly connected to the insertion rod 89. The return spring 812 provides power for the return movement of the cleaning rod 811. The magnetic cutting plate 87 is made of magnetic soft iron with high permeability and low remanence to efficiently cut magnetic lines of force and generate induced current. Among them, multiple sets of protrusions 813 are fixedly connected to the side wall of the housing 1 directly above the cleaning rod 811. The protrusions 813 are made of stainless steel with high hardness to withstand continuous periodic impacts with the cleaning rod and are wear-resistant.

[0025] The lower end of the housing 1 is rotatably connected to a lower pulley 821, which is connected to an upper pulley 82 via a belt drive. Multiple sets of stirring blades are fixedly connected to the side wall of the guide shaft 822, which control the airflow speed inside the housing 1. The lower pulley 821 is fixedly connected to the guide shaft 822, which is coaxially fixedly connected to a receiving wheel 824. The receiving wheel 824 is rotatably connected to a circular groove 823. The upper end of the circular groove 823 is connected to the area below the filter screen 810, and the bottom area of ​​the circular groove 823 has a discharge port 825. The blades or grooves on the rotating receiving wheel 824 capture and convey impurities downwards, ultimately transporting them to the discharge port 825 at the bottom of the circular groove 823 for centralized collection or discharge, achieving automatic impurity recovery and eliminating the need for manual cleaning.

[0026] In this configuration, the cable connecting the transformer 9 and the battery 7 is wound around the magnetic cutting plate 87 to form a coil, and the magnetic field formed on the coil cuts the magnetic cutting plate 87. The magnetic cutting plate 87 is connected to the electromagnetic spring 52 through the cable, and the opening and closing of the electromagnetic spring 52 is controlled by the cable, so that the air inlet and outlet of the enclosure 1 move, stop or close with the magnetic cutting plate 87. When the guide fan 8 stops, the magnetic cutting plate 87 stops, the induced current disappears, the electromagnetic spring 52 is de-energized and demagnetized, the inner plate 53 moves back, so that its guide hole 54 is misaligned with the guide hole 54 of the outer frame 51, thereby closing the air duct and preventing dust, moisture or foreign objects from entering the enclosure when it is not in operation.

[0027] This invention provides a grid-type energy storage converter, the working principle of which is as follows: The flow guide fan 8 is started, driving the drive shaft 81 to rotate. The drive shaft 81 drives the first connecting rod 84 to rotate, and the second connecting rod 85 drives the magnetic cutting plate 87 to reciprocate. The magnetic cutting plate 87 also drives the transmission rod 88 to move, which in turn drives the insertion rod 89 to reciprocate left and right. The cleaning rod 811 brushes the surface of the filter screen 810, and while moving, the top of the cleaning rod 811 presses against the protrusion 813, causing the cleaning rod 811 to slide up and down while moving left and right, improving the cleaning effect on the surface of the filter screen 810. The magnetic cutting plate 87 cuts magnetic lines of force while moving. The magnetic cutting plate 87 energizes the electromagnetic spring 52 through a cable, causing the electromagnetic spring 52 to move the inner plate 53. The flow guide holes on the inner plate 53... The guide hole 54 on the outer frame 51 overlaps with the guide hole 54, allowing external air to enter the interior of the box 1. When the magnetic cutting plate 87 stops, the electromagnetic spring 52 is de-energized, causing the electromagnetic spring 52 to move and reset the inner plate 53. The inner plate 53 is offset from the guide hole 54 on the outer frame 51, so that the interior of the box 1 is closed. When the drive shaft 81 rotates, the drive shaft 81 drives the upper pulley 82 to rotate. The upper pulley 82 drives the lower pulley 821 to rotate through the belt. The lower pulley 821 drives the receiving wheel 824 to rotate through the guide shaft 822, so that the impurities falling from above are received by the receiving wheel 824. The receiving wheel 824 drives the impurities to rotate downward to the discharge port 825 area, which facilitates the subsequent recovery of impurities. The processing and recovery of impurities on the filter screen 811 can be controlled by the guide fan 8.

[0028] This invention uses a flow guide fan 8 to drive a connecting rod, causing the cleaning rod 811 to move back and forth. During this movement, the top of the rod presses against the protrusion 813, achieving both left and right movement and up and down sliding. This improves the cleaning effect on the surface of the filter screen 810, ensures unobstructed heat dissipation channels, and facilitates heat dissipation of the equipment.

[0029] The present invention drives the upper pulley 82 and the lower pulley 821 to rotate by rotating the drive shaft 81, which in turn drives the receiving wheel 824 to rotate, so that the impurities falling from above are received by the receiving wheel 824 and driven to rotate downward to the discharge port 825 area, which facilitates the subsequent recovery of impurities and keeps the inside of the equipment clean.

[0030] This invention uses a magnetic cutting plate 87 to move and cut magnetic lines of force, which energizes an electromagnetic spring 52 and causes the inner plate 53 to move so that the inner plate 53 overlaps with the guide hole 54 on the outer frame 51, allowing external air to enter the interior of the housing 1. When the magnetic cutting plate 87 stops, the electromagnetic spring 52 is de-energized, causing the inner plate 53 to move and reset, and the guide hole 54 is staggered so that the interior of the housing 1 is in a closed state, allowing for flexible control of ventilation according to the equipment's operating conditions.
