[0035] Reference Figure 1-3 As shown in the figure, this application embodiment provides an emergency response power supply device, which includes a cabinet 1 and an emergency response power supply 2 disposed in the cabinet 1, wherein the cabinet 1 is provided with an interface for the emergency response power supply 2 to connect to the outside.

[0036] Reference Figure 1 As shown, a flexible waterproof cover 3 is provided outside the cabinet 1. The flexible waterproof cover 3 is cylindrical and sleeved outside the cabinet 1. The flexible waterproof cover 3 includes a fixed end 31 and a movable end 32. The fixed end 31 is sealed to the bottom of the cabinet 1, and the movable end 32 can move relative to the cabinet 1 along the height direction of the cabinet 1.

[0037] In order to enable the movable end 32 of the flexible waterproof cover 3 to rise to a sufficient height, the interface position on the cabinet 1 is set near the middle or top, and the maximum height of the movable end 32 of the flexible waterproof cover 3 is lower than the height of the interface, so as to avoid the line led out from the emergency response power supply 2 and passing through the cabinet 1 from obstructing the flexible waterproof cover 3 from enclosing the cabinet 1.

[0038] Reference Figure 1-2 As shown, a drive assembly 4 is provided between the cabinet 1 and the flexible waterproof cover 3. The drive assembly 4 connects the movable end 32 of the flexible waterproof cover 3 and the cabinet 1. The drive assembly 4 is used to drive the movable end 32 to move along the height direction of the cabinet 1.

[0039] Reference Figure 1-2 As shown, specifically, the drive assembly 4 includes a drive ring 41, a drive screw 42, and a motor 43. The drive ring 41 surrounds the cabinet 1 and is movable relative to the cabinet 1 along its height direction. The movable end 32 of the flexible waterproof cover 3 is connected to the drive ring 41. The drive screw 42 is located outside the cabinet 1 and its length direction is parallel to the height direction of the cabinet 1. The drive screw 42 is rotatably connected to the cabinet 1 and threadedly connected to the drive ring 41. The motor 43 is located inside the cabinet 1 and connected to the drive screw 42 through a transmission structure, so as to drive the drive screw 42 to rotate.

[0040] Since the drive ring 41 is sleeved outside the cabinet 1 and is obstructed by the cabinet 1 from rotating with the drive screw 42, when the motor 43 drives the drive screw 42 to rotate, the drive ring 41 is driven by the drive screw 42 to move along the height direction of the cabinet 1, which in turn drives the movable end 32 of the flexible waterproof cover 3 to move along the height direction of the cabinet 1.

[0041] Reference Figure 2 As shown, the transmission structure includes a transmission shaft 44, the axis of which is perpendicular to the axis of the drive screw 42. One end of the transmission shaft 44 is coaxially fixed to the output shaft of the motor 43, and the other end passes through the cabinet 1 and is coaxially connected to a driving bevel gear 45. One end of the drive screw 42 is coaxially connected to a driven bevel gear 46, which meshes with the driving bevel gear 45.

[0042] Specifically, the drive shaft 44 and the motor 43 are located near the upper end of the drive screw 42. The drive screw 42 is rotatably mounted on the outer wall of the back of the cabinet 1 via two lugs. The drive shaft 44 is mounted on the cabinet 1 via bearings, and the motor 43 is fixed to the inner wall of the cabinet 1.

[0043] A guide rod is also provided on the back of the cabinet 1. The axis of the guide rod is parallel to the axis of the drive screw 42. A guide block that can move along its axis is sleeved on the guide rod. The guide block is fixed to the drive ring 41. Specifically, the guide rod is also installed on the outer wall of the cabinet 1 through the ear plate. The guide rod and the drive screw 42 are distributed at intervals in the width direction of the back of the cabinet 1.

[0044] Reference Figure 1-2As shown, the drive ring 41 is configured with a gap between it and the outer wall of the cabinet 1. The drive ring 41 is fixedly connected to a connecting block 411 that is threadedly connected to the drive screw 42. The gap between the drive ring 41 and the outer wall of the cabinet 1 can prevent the movement of the drive ring 41 from being hindered due to the cabinet door not closing tightly or other situations, thus preventing the flexible waterproof cover 3 from rising smoothly.

[0045] Furthermore, to automatically raise the flexible waterproof cover 3 when the water level near cabinet 1 reaches the warning height, a liquid level detection device is installed outside cabinet 1 near cabinet 1. This device is positioned outside the flexible waterproof cover 3 and close to the ground to detect the water level near cabinet 1. Specifically, the liquid level detection device is a liquid level sensor. A controller is installed inside cabinet 1, electrically connected to motor 43 and the liquid level sensor. The liquid level sensor is electrically connected to the controller via wiring that runs through cabinet 1. When the liquid level sensor detects that the liquid level has reached the warning height, the controller controls motor 43 to start and raise the flexible waterproof cover 3. The controller is existing technology and will not be described in detail here.

[0046] The height of the liquid level sensor from the ground and its horizontal distance from the cabinet 1 are set as needed, and the height must be lower than the initial height of the movable end 32 when it is not raised.

[0047] With the above settings, the liquid level sensor monitors the water level near the cabinet 1 in real time. When the water level exceeds the set value, the drive component 4 starts to drive the movable end 32 of the flexible waterproof cover 3 to move upward, causing the flexible waterproof cover 3 to rise and cover a section of the bottom of the cabinet 1. The flexible waterproof cover 3 blocks external water accumulation or floods, preventing water from entering the cabinet 1, thereby protecting the emergency response power supply 2.

[0048] Furthermore, the total length of the flexible waterproof cover 3 is set to be greater than the maximum height of its movable end 32 when it rises, so that the flexible waterproof cover 3 is in a relaxed state when it is raised. In this way, under the action of water pressure, the flexible waterproof cover 3 can be pressed tightly against the outer wall of the cabinet 1, so that the water pressure acts on the cabinet 1, making the flexible waterproof cover 3 less likely to break due to water pressure or collision with debris carried in the water, thus providing stable protection.

[0049] Reference Figure 1 and Figure 3 As shown, furthermore, in order to facilitate the replacement of the flexible waterproof cover 3, both the fixed end 31 and the movable end 32 of the flexible waterproof cover 3 are connected to a connecting ring 5. The fixed end 31 and the movable end 32 are respectively sealed to the corresponding connecting ring 5. The drive ring 41 can pass through the connecting ring 5. The connecting ring 5 of the movable end 32 can be detached from the drive ring 41. The connecting ring 5 of the fixed end 31 can be detached from the cabinet 1.

[0050] Reference Figure 1 and Figure 3As shown, the connecting ring 5 of the movable end 32 is wrapped around the drive ring 41 and fixed by bolts during installation. In order to achieve the connection and sealing between the connecting ring 5 of the fixed end 31 and the cabinet 1, an installation ring 6 is connected to the cabinet 1. The installation ring 6 is set around the cabinet 1 and is close to the bottom of the cabinet 1 and is sealed to the cabinet 1. The connecting ring 5 of the fixed end 31 is wrapped around the installation ring 6 and can be detachably connected to the installation ring 6. When connected, a seal is formed by a sealing ring.

[0051] Reference Figure 1 and Figure 3 As shown, specifically, the mounting ring 6 is welded and fixed to the cabinet 1, and a seal is formed between the inner side of the mounting ring 6 and the outer wall of the cabinet 1. The connecting ring 5 of the fixed end 31 of the flexible waterproof cover 3 surrounds the mounting ring 6 and is fixedly connected to the mounting ring 6 by bolts. A sealing ring is set between the mounting ring 6 and the connecting ring 5 to achieve a seal.

[0052] When replacing the flexible waterproof cover 3, separate the mounting ring 6 and drive ring 41 from the corresponding connecting ring 5, disconnect the wiring extending from the cabinet 1 from the corresponding equipment, move the connecting ring 5 along with the flexible waterproof cover 3 to the top of the cabinet 1 until it detaches from the cabinet 1, and then put the replacement flexible waterproof cover 3 on the outside of the cabinet 1 in the reverse order, and connect the mounting ring 6 and drive ring 41 to the corresponding connecting ring 5. This achieves a detachable connection of the flexible waterproof cover 3 to the cabinet 1, allowing it to be replaced when damaged so it can function during the next water level rise.

[0053] Reference Figure 1 and Figure 3 As shown, the connecting ring 5 connected to the fixed end 31 is provided with a receiving groove 51, in which the flexible waterproof cover 3 can be stored. Specifically, the receiving groove 51 is provided on the top end face of the connecting ring 5 and is formed around the circumference of the connecting ring 5. The fixed end 31 of the flexible waterproof cover 3 is fixed and sealed to the bottom of the receiving groove 51. When the movable end 32 is not raised, the flexible waterproof cover 3 is folded and stored in the receiving groove 51. At the same time, the connecting ring 5 connected to the movable end 32 covers the receiving groove 51 to prevent the flexible waterproof cover 3 from being exposed to the outside and damaged by foreign objects.

[0054] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
