[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0022] Please refer to a ring main unit with an emergency power supply mechanism. Figures 1-2 The device includes an outer casing 1, a canopy 2 on the top of the outer casing 1, sloping surfaces near the front and rear sides of the top of the canopy 2, a rain collection trough 3 on the top of the sloping surfaces, a guide filter hole 4 near one end of the bottom of the rain collection trough 3, a travel device 5 movably installed near both ends of the top of the canopy 2, a cooling fan 6 near the top of the back of the outer casing 1, a locking device 7 fixedly installed near the top of the front side of the inner wall of the outer casing 1, and an installation box 8 placed at the bottom of the inner cavity of the outer casing 1.

[0023] Please see Figures 1-2 A second drain hole 9 is provided at the bottom of the inner cavity of the outer casing 1 near the front side. The front end of the second drain hole 9 extends to the front of the outer casing 1 near the bottom and is connected to the outside. A second connecting hole 10 is provided at the bottom of the inner cavity of the outer casing 1 near the back side. A liquid storage chamber 11 is provided at the back of the outer casing 1 near the bottom. A pressure sensing plate 12 is provided at the bottom of the liquid storage chamber 11. The second connecting hole 10 is connected to the liquid storage chamber 11. A second air outlet 13 is provided on both sides of the outer surface of the outer casing 1 near the bottom.

[0024] Please see Figures 2-3 The travel device 5 includes a travel rod 51, which is connected to the canopy 2 by telescopic movement. A top plate 52 is fixedly installed on the top of the travel rod 51. Cleaning rods 53 are movably sleeved at both ends of the top plate 52. The front end of the cleaning rod 53 is provided with an inclined surface and cooperates with the rain collection trough 3. A spring seat 54 is provided on the outer surface of the travel rod 51 near the bottom. A return spring 55 is provided on the top of the spring seat 54 at the position outside the travel rod 51. The top of the return spring 55 contacts the top of the inner wall of the canopy 2. A rain storage device 56 is fixedly installed at the bottom of the travel rod 51.

[0025] The top plate 52 is pulled down by the travel rod 51. Since the front end of the cleaning rod 53 is located inside the rainwater collection trough 3, as the top plate 52 moves down, the front end of the cleaning rod 53 slides along the rainwater collection trough 3, which cleans the inside of the rainwater collection trough 3. This prevents debris from accumulating inside the rainwater collection trough 3 and affecting the flow of rainwater, thus preventing rainwater from being stored properly in the rainwater storage tank 561. This improves the reliability of the device. At the same time, when the rainwater storage tank 561 moves down to its limit position, the cleaning rod 53 fully engages with the rainwater collection trough 3 and blocks the guide filter hole 4, thereby preventing subsequent rainwater from continuing to enter the inside of the rainwater storage tank 561 through the guide filter hole 4. This prevents rainwater from overflowing and damaging the internal equipment of the installation box 8, thus improving the reliability of the device.

[0026] Please see Figures 3-5 The rain storage device 56 includes a rain storage tank 561, a top cover 562 on the top of the rain storage tank 561, and three collection holes 563 arranged in a linear array on the top of the top cover 562. A telescopic shaft seat 564 is fixedly installed on the top of the rain storage tank 561 near the front end, and a locking device 57 is movably installed inside the telescopic shaft seat 564. A rain discharge pipe 565 is provided at the bottom of the rain storage tank 561, and the rain discharge pipe 565 is connected to the inner cavity of the rain storage tank 561. A rain baffle 566 is provided on the inner cavity of the rain discharge pipe 565 near the bottom. A guide device 58 is fixedly installed on the back of the rain storage tank 561. Please see Figures 3-5 As the amount of rainwater inside the rainwater storage tank 561 increases, it will pull the return spring 55 to move downwards.

[0027] This device can store rainwater. When it rains, the rainwater falls into the rain collection trough 3 and flows along it to the guide filter hole 4. The guide filter hole 4 can filter impurities in the rainwater. The filtered rainwater falls through the guide filter hole 4 to the top of the locking device 57. Since the travel hole 576 and the collection hole 563 are in a corresponding relationship at this time, the rainwater enters the rain storage tank 561 through the travel hole 576 and the collection hole 563 and is stored. As the amount of rainwater stored in the rain storage tank 561 increases, the rain storage device 56 moves downward due to its own weight. Since the liquid inlet pipe 84 is located at the rain discharge point... Directly below pipe 565, when the rain storage tank 561 moves to its extreme position, the liquid inlet pipe 84 extends into the interior of the rain discharge pipe 565 and pushes open the rain baffle 566. The rainwater stored inside the rain storage tank 561 enters the interior of the guide channel 83 through the rain discharge pipe 565 and the liquid inlet pipe 84. During the flow inside the guide channel 83, it plays a role in cooling the equipment inside the main body 81, preventing the device from being under high load. When air cooling cannot completely suppress the equipment temperature, additional cooling methods can be used to ensure that the device is in the best operating state, thus improving the practicality of the device.

[0028] Please see Figures 5-7 The locking device 57 includes a sliding plate 571. A baffle plate 572 is fixedly installed on the top of the sliding plate 571 near its end. A spring rod 573 is fixedly installed on the front end of the sliding plate 571. A triangular locking block 574 is fixedly installed on the front end of the spring rod 573. A locking groove 575 is opened at the bottom of the triangular locking block 574. A travel hole 576 is opened at the top of the locking groove 575. The number of travel holes 576 is three and distributed in a linear array. In the initial state, the travel holes 576 correspond to the collection hole 563.

[0029] When the rain storage tank 561 moves to its extreme position, the airflow generated by the cooling fan 6 acts on the back of the baffle plate 572, thereby pushing the locking device 57 to move closer to the locking device 7, so that the triangular locking block 574 can be inserted into the triangular locking groove 72 for positioning. In addition, when the sliding plate 571 moves, the travel hole 576 and the collection hole 563 can be misaligned, and the collection hole 563 can be closed, which can prevent the liquid inside the rain storage tank 561 from being blown out by the airflow and causing overflow, thus improving the stability of the device during operation.

[0030] Please see Figure 3 , Figure 6 and Figure 10 When the rainwater storage device 56 drops to its limit position due to the weight of the rainwater, the triangular locking block 574 corresponds to the triangular locking groove 72.

[0031] Please see Figures 8-9The guiding device 58 includes a guiding box 581. A lower guiding plate 582 is fixedly installed in the lower part of the inner cavity of the guiding box 581. An upper guiding plate 583 is fixedly installed in the upper part of the inner cavity of the guiding box 581. A rectangular groove is opened on the top of the upper guiding plate 583, and an air guide flap 584 is movably installed inside the rectangular groove. The air guide flap 584 can only rotate clockwise.

[0032] When the rainwater storage tank 561 is storing rainwater and moving downwards to the middle position, the guiding device 58 will be in a state corresponding to the cooling fan 6. At this time, the airflow generated by the cooling fan 6 passes between the lower guide plate 582 and the upper guide plate 583, and under the action of air pressure, the air guide flap 584 is in the open state. At this time, the airflow enters the upper part of the rainwater storage device 56 through the air guide flap 584. Since the cleaning rod 53 is not fully engaged with the rainwater collection trough 3 at this time, and the guide filter hole 4 is still in the open state, the airflow can enter the external environment through the guide filter hole 4. During this process, the airflow can clean the debris stuck inside the guide filter hole 4, preventing this debris from entering the interior of the outer casing 1 and causing pollution under the pushing of the cleaning rod 53, thus improving the practicality of the device. In addition, when the rain storage box 561 moves down to the limit position, the cleaning rod 53 is fully engaged with the rain collection trough 3, and the guide filter hole 4 is also blocked, so that the airflow can no longer enter the external environment through the guide filter hole 4. This allows the airflow to still be cooled and dissipated through the air inlet 85, the side hole 87, and the guide channel 83, thus improving the practicality of the device.

[0033] Please see Figures 11-13 The installation box 8 includes a main box body 81. Side compartments 82 are provided on both sides of the inner cavity of the main box body 81. A flow channel 83 is provided at the top of the inner cavity of the main box body 81 between the side compartments 82. The flow channel 83 extends from the top and back of the inner cavity of the main box body 81 to the bottom. A liquid inlet pipe 84 is provided at the top of the main box body 81 and is connected to the cavity of the flow channel 83. An air inlet 85 is provided at the top of the main box body 81 near the front side. A first air outlet 86 is provided at the top of the main box body 81 near both sides and is connected to the side compartments 82. Side holes 87 are provided at both sides of the main box body 81 near the bottom. A first drain hole 88 and a first connecting hole 89 are provided at the bottom of the main box body 81 near the front and rear sides, respectively. Both the first drain hole 88 and the first connecting hole 89 are connected to the inner cavity of the flow channel 83.

[0034] Please see Figure 5 and Figures 11-12 The liquid inlet pipe 84 is located directly below the rain discharge pipe 565.

[0035] Please see Figure 2 and Figure 12The first drain hole 88 and the second drain hole 9 are in a connected state, and the first connecting hole 89 and the second connecting hole 10 are in a connected state.

[0036] Please see Figure 10 The locking device 7 includes a mounting plate 71. A triangular locking groove 72 is provided on the front of the mounting plate 71 near the bottom. A telescopic mechanism 73 is fixedly installed on the bottom of the mounting plate 71. A latch is installed on one end of the output shaft of the telescopic mechanism 73 and extends into the interior of the triangular locking groove 72. The front of the mounting plate 71 above the triangular locking groove 72 is set as an inclined surface.

[0037] Please see Figures 6-7 , Figure 10 The triangular locking groove 72 has the same structure and shape as the triangular locking block 574. After the triangular locking groove 72 extends into the triangular locking block 574 and the telescopic machine 73 is running, the buckle installed at one end of the output shaft of the telescopic machine 73 cooperates with the locking groove 575. The output end of the pressure sensing plate 12 is connected to the telescopic machine 73 through mutual connection.

[0038] When rainwater stored in the rainwater storage tank 561 enters the interior of the guide channel 83, some of the rainwater enters the liquid storage chamber 11 through the first drain hole 88 and the second connecting hole 10. During the flow of rainwater within the guide channel 83, the water level is at its highest point, and the pressure sensor plate 12 experiences maximum liquid pressure. At this time, the output end of the pressure sensor plate 12 is connected to the telescopic mechanism 73, triggering the telescopic mechanism 73. The output shaft drives the latch to extend and engage with the locking groove 575, locking the groove. The triangular locking block 574 cannot retract, preventing the rainwater in the storage tank 561 from rising after some rainwater is consumed, thus preventing the rainwater from stopping flowing inside the storage tank 561. The internal supply of the guide channel 83 is prevented, thus preventing the liquid from cooling properly. When the rainwater stored in the rain tank 561 is exhausted, all the rainwater flowing inside the guide channel 83 is discharged through the first drain hole 88 and the second drain hole 9. At this time, the liquid level drops, and the liquid pressure on the pressure sensing plate 12 reaches its minimum value. At this time, the telescopic mechanism 73 stops triggering and drives the latch to retract, releasing the engagement with the locking groove 575. Under the elastic force of the return spring 55 and the guiding action of the inclined surface at the front end of the triangular locking block 574, the triangular locking block 574 disengages from the inside of the triangular locking groove 72. The rain tank 561, which has lost its locking effect, moves up to the initial position under the action of the return spring 55, forming a complete cycle and improving the automation level of the device.

[0039] The method of using this invention is as follows: When it rains, rainwater falls into the rain collection trough 3 and flows along it to the guide filter hole 4. The guide filter hole 4 filters out impurities in the rainwater. The filtered rainwater falls through the guide filter hole 4 to the top of the locking device 57. Since the travel hole 576 and the collection hole 563 are in a corresponding relationship at this time, the rainwater enters the rain storage tank 561 through the travel hole 576 and the collection hole 563 and is stored. As the amount of rainwater stored in the rain storage tank 561 increases, the rain storage device 56 moves downward due to its own weight. Since the liquid inlet pipe 84 is located directly below the rain discharge pipe 565, when the rain storage tank 561 moves to its limit position, the liquid inlet pipe 84 extends into the rain discharge pipe 565 and pushes open the rain baffle 566, and the rainwater stored inside the rain storage tank 561 flows through... The rainwater flows through the unloading pipe 565 and the inlet pipe 84 into the guide channel 83. During the flow within the guide channel 83, it cools the equipment inside the main housing 81, preventing the device from operating under high load. When air cooling cannot completely control the equipment temperature, additional cooling methods ensure the device operates at its optimal state. The top plate 52 is lowered by the stroke rod 51. Since the front end of the cleaning rod 53 is located inside the rainwater collection trough 3, as the top plate 52 moves downward, the front end of the cleaning rod 53 slides along the rainwater collection trough 3, effectively cleaning the inside of the rainwater collection trough 3. When the rainwater storage tank 561 moves to its limit position, the cleaning rod 53 fully engages with the rainwater collection trough 3, blocking the guide filter hole 4, thereby preventing subsequent rainwater from continuing to flow through the guide channel. The filter hole 4 enters the interior of the rainwater storage tank 561. When the rainwater storage tank 561 is storing rainwater and moving downwards to the middle position, the guide device 58 will be in a state corresponding to the cooling fan 6. At this time, the airflow generated by the cooling fan 6 passes through the position between the lower guide plate 582 and the upper guide plate 583, and under the action of air pressure, the air guide flap 584 is in the open state. At this time, the airflow enters the upper part of the rainwater storage device 56 through the air guide flap 584. Since the cleaning rod 53 is not fully engaged with the rainwater collection trough 3 at this time, and the guide filter hole 4 is still in the open state, the airflow can enter the external environment through the guide filter hole 4. During this process, the airflow can clean the debris stuck inside the guide filter hole 4. When the rainwater storage tank 561 moves downwards to the extreme position... When the rainwater collection tank 561 is in its limit position, the cleaning rod 53 is fully engaged with the rainwater collection trough 3, and the guide filter hole 4 is also blocked, preventing airflow from entering the external environment. The airflow still passes through the air inlet 85, side hole 87, and guide channel 83 for cooling. When the rainwater collection tank 561 moves to its limit position, the airflow generated by the cooling fan 6 acts on the back of the baffle plate 572, pushing the locking device 57 towards the locking device 7. This allows the triangular locking block 574 to insert into the triangular locking groove 72 for positioning. Furthermore, during the movement of the sliding plate 571, the travel hole 576 and the collection hole 563 are misaligned, and the collection hole 563 is closed.This design avoids the problem of liquid overflowing from the rainwater storage tank 561 due to airflow. When rainwater stored in the rainwater storage tank 561 enters the guide channel 83, some of the rainwater enters the storage chamber 11 through the first drain hole 88 and the second connecting hole 10. During the flow of rainwater within the guide channel 83, the water level is at its highest point, and the pressure sensor 12 experiences maximum liquid pressure. At this time, the output end of the pressure sensor 12 is connected to the telescopic mechanism 73, triggering the telescopic mechanism 73. The output shaft drives the latch to extend and engage with the locking groove 575, causing the locking groove 575 to engage. In the locked state, the triangular locking block 574 cannot retract. When the rainwater stored inside the rainwater storage tank 561 is exhausted, all the rainwater flowing inside the guide channel 83 is discharged through the first drain hole 88 and the second drain hole 9. At this time, the liquid level drops, and the liquid pressure on the pressure sensing plate 12 reaches its minimum value. At this time, the telescopic mechanism 73 stops triggering and drives the latch to retract, releasing the engagement with the locking groove 575. At this time, under the elastic force of the return spring 55 and the guiding action of the inclined surface at the front end of the triangular locking block 574, the triangular locking block 574 disengages from the inside of the triangular locking groove 72. The rainwater storage tank 561, which has lost its locking effect, moves upward to the initial position under the action of the return spring 55.
