Description

Technical Field

[0001] This invention relates to the field of power distribution facilities technology, and more specifically, to an integrated power distribution control cabinet. Background Technology

[0002] Power distribution control cabinets are key infrastructure for power transmission and distribution, industrial automation, communication base stations, etc. They typically contain sophisticated and expensive power distribution control components such as circuit breakers, contactors, PLCs, and frequency converters. The safe and stable operation of these components is crucial to the reliability of the entire system.

[0003] Currently, a major threat to outdoor power distribution control cabinets is the intrusion of liquid water (rainwater). Although existing standards (IP protection rating) require the cabinet itself to have a certain level of waterproof performance (IPX4 splash-proof, IPX5 jet-proof, etc.), in practical applications, especially under conditions of continuous heavy rainfall, typhoons, or extreme weather, the following significant risks still exist: Sealing aging: Components such as cabinet door sealing strips and wire hole sealing sleeves will age and crack over time and with temperature changes, resulting in a decline in sealing performance and the inability to continuously guarantee waterproofing. Impact of ventilation components: To control the temperature inside the cabinet, the cabinet is usually designed with ventilation louvers, but this is fundamentally contradictory to the high-level waterproof requirements, and rainwater can easily enter from here; Extreme weather exceeding limits: Existing static protection designs are designed for specific test conditions. When encountering extreme rainfall that far exceeds the design standards, rainwater may seep in through various gaps.

[0004] Once water enters the system, it can easily cause serious accidents such as electrical short circuits, equipment burnout, and system shutdown, resulting in economic losses and safety risks.

[0005] Existing advanced solutions are beginning to incorporate the concept of active protection, such as using humidity sensors to monitor the condition inside the cabinet and activating heating and dehumidification when the humidity exceeds the standard. However, this solution still only reacts after water vapor has entered the cabinet, and its response speed and protection effect are insufficient for sudden intrusion of a large amount of liquid water. Summary of the Invention

[0006] This invention provides an integrated power distribution control cabinet, which solves the technical problems in related technologies where water vapor has already entered the cabinet and caused some impact during water vapor protection, and the related protection mechanisms have slow response speed and poor effect.

[0007] This invention provides an integrated power distribution control cabinet, including a cabinet body, a base, power distribution control elements, a protection sensing module, a protection execution module, and a circuit breaker. The cabinet body is fixedly mounted on the top of the base, and a door panel is rotatably mounted on the cabinet body. A partition is provided between the base and the cabinet body, and a bracket is fixedly mounted above the partition. The power distribution control elements are slidably mounted above the bracket. A circuit breaker is installed on the base to control the connection and disconnection between the power distribution control elements and external circuits. The protection sensing module is installed on the outside of the cabinet body and senses changes in rainfall to drive the protection execution module to operate. The base has an external heat dissipation groove, and the partition has an internal heat dissipation groove, which is connected to the external heat dissipation groove.

[0008] Driven by the protection sensing module, the protection execution module forms a waterproof blocking surface at the opening on the side of the cabinet facing the door panel; Driven by the protection sensing module, the protection execution module covers and seals the inner heat dissipation slot; Driven by the protection sensing module, the protection execution module toggles the circuit breaker to block the power distribution control element from the external circuit; Driven by the protection sensing module, the protection execution module pushes the power distribution control element upward.

[0009] As a further aspect of the present invention: the protection sensing module includes a controller, a storage box, and a water level sensor. The controller is fixedly installed on the top of the cabinet and electrically connected to the protection execution module. A storage box is fixedly installed on one side of the cabinet, and a water level sensor electrically connected to the controller is installed in the storage box.

[0010] As a further embodiment of the present invention: the protective execution module includes a first electric roller, a barrier layer, a bottom strip, a track, a traction rope, a second electric roller, a turning roller, a cover, and a protruding plate. The first electric roller is provided on the top of the cabinet, and a barrier layer is wound around the first electric roller. A bottom strip is fixedly provided on the side of the barrier layer away from the first electric roller. Tracks are symmetrically arranged inside the cabinet, and the bottom strip slides in cooperation with the track. A second electric roller is provided above the partition, and a traction rope is wound around the second electric roller. The end of the traction rope away from the second electric roller is fixedly connected to the bottom strip. A turning roller is fixedly installed on the partition, and the traction rope changes direction by 90 degrees through the turning roller. A cover is fixedly installed on the traction rope, and the cover slides in cooperation with the inner heat dissipation groove. A protruding plate is fixedly installed on the bottom strip, and the protruding plate cooperates with the circuit breaker.

[0011] As a further aspect of the present invention, the barrier layer is made of fibers with high water absorption.

[0012] As a further aspect of the present invention: the track is L-shaped, with the turning point being arc-shaped.

[0013] As a further aspect of the present invention: a sleeve is installed on the bracket, and a sliding column is slidably installed in the sleeve, with the top end of the sliding column fixedly connected to the bottom of the power distribution control element.

[0014] As a further embodiment of the present invention: a rotating shaft is rotatably installed in the cabinet, and a synchronous belt drive device is provided between the rotating shaft and the output end of the second electric roller. A gear is fixedly installed at the end of the rotating shaft, and a rack that cooperates with the gear is fixedly installed on the back side of the power distribution control element.

[0015] As a further aspect of the present invention: the circuit breaker is provided with a lever for controlling the switch state, and the convex plate makes contact with the lever when it moves.

[0016] The beneficial effects of this invention are as follows: This invention, through a rainfall monitoring mechanism, can detect and trigger actions before rainwater accumulates to a dangerous level. This proactive early warning and intervention mode changes the protection node from a passive handling "after water has invaded" to an active blocking "when water is about to invade," fundamentally avoiding contact between liquid water and electrical equipment and achieving true preventive protection.

[0017] This invention links mechanical action (barrier layer in place) with electrical safety (circuit breaker) through a toggle switch. This means that there is both the establishment of a physical barrier under normal conditions and the forced power cut-off of the core circuit under emergency conditions. This design eliminates secondary disasters such as short circuits, electric arcs, equipment burnout, and even fires that may be caused by water ingress, providing the highest level of safety for equipment and personnel.

[0018] When the protective execution module is activated, the present invention takes into account the impact of extreme situations. The rotation output of the second electric roller is transported to the shaft side through a synchronous belt drive. The rotation of the shaft drives the gear to rotate, and then meshes with the rack, thereby causing the power distribution control element to move upward and be raised, avoiding damage caused by direct immersion in water.

[0021] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed only to enable those skilled in the art to better understand and implement the subject matter described herein, and changes may be made to the function and arrangement of the elements discussed without departing from the scope of this specification. Various processes or components may be omitted, substituted, or added as needed in the examples. Furthermore, features described in some examples may be combined in other examples.

[0022] This invention discloses an integrated power distribution control cabinet, such as Figure 1 - Figure 8 As shown, the device includes a cabinet 1, a base 2, a power distribution control element 6, a protection sensing module 7, a protection execution module 8, and a circuit breaker 9. The cabinet 1 is fixedly mounted on the top of the base 2, and a door panel 3 is rotatably mounted on the cabinet 1. A partition 4 is provided between the base 2 and the cabinet 1. A bracket 5 is fixedly mounted above the partition 4, and the power distribution control element 6 is slidably mounted above the bracket 5, which is achieved by the relative sliding of the sliding column 52 and the sleeve 51. A circuit breaker 9 is installed on the base 2 to control the connection and disconnection of the power distribution control element 6 with the external circuit. The protection sensing module 7 is installed on the outside of the cabinet 1 and senses changes in rainfall to drive the operation of the protection execution module 8. The base 2 is provided with an outer heat dissipation groove 21, and the partition 4 is provided with an inner heat dissipation groove 41, which is connected to the outer heat dissipation groove 21.

[0023] Driven by the protection sensing module 7, the protection execution module 8 forms a waterproof blocking surface at the opening on the side of the cabinet 1 facing the door panel 3; Driven by the protection sensing module 7, the protection execution module 8 covers and seals the inner heat dissipation slot 41. Driven by the protection sensing module 7, the protection execution module 8 toggles the circuit breaker 9 to block the power distribution control element 6 from the external circuit. Driven by the protection sensing module 7, the protection execution module 8 pushes the power distribution control element 6 upward.

[0024] This invention provides a progressive moisture protection mechanism to protect the core component of the power distribution control cabinet, namely the power distribution control element 6, in heavy rainfall environments. Specifically: The protection sensor module 7 acts as a trigger point, monitoring changes in rainfall in real time and driving the protection execution module 8 to perform moisture protection. The protection execution module 8 is based on a movement action. The magnitude of this movement action is positively correlated with the amount of rainfall applied by the external environment. Based on the amount of rainfall, the protection execution can be divided into two states: normal protection and emergency protection. In the normal protection state, the movement action simultaneously achieves the blocking of the opening side of the cabinet 1 (preventing water from entering through the gaps), the sealing of the heat dissipation duct (preventing water from entering), and raising the height of the power distribution control element 6 (preventing water immersion). In the emergency protection state, the movement action further increases in magnitude, passing the location of the circuit breaker 9, thereby triggering the circuit breaker 9, blocking the power distribution control element 6 from the external circuit, and realizing power outage protection.

[0025] The protection sensing module 7 includes a controller 71, a storage box 72, and a water level sensor 73. The controller 71 is fixedly installed on the top of the cabinet 1 and is electrically connected to the protection execution module 8. The storage box 72 is fixedly installed on one side of the cabinet 1, and the water level sensor 73, which is electrically connected to the controller 71, is installed in the storage box 72.

[0026] During rainfall sensing, the storage box 72 is used to collect rainfall. The water level sensor 73 senses the change in water level in the storage box 72, and the controller 71 converts it into rainfall. Then, based on the amount of rainfall, it drives the protection execution module 8 to run.

[0027] It is important to note that the storage tank is designed to account for water storage. After rainfall stops, it will actively drain the water (the corresponding active drainage structure is not shown) to avoid affecting subsequent monitoring. Furthermore, the combination of the storage tank and water level sensor 73 for measuring rainfall can be directly replaced with a rain gauge sensor. The principle behind the active drainage of the storage tank is... Figure 2The storage tank shown has an opening at the bottom, a plug that slides and extends relative to the opening, and an electric push rod that drives the plug. The electric push rod works in conjunction with a rain sensor. When the rain sensor detects that rainfall has stopped, the electric push rod pushes the plug down to open the opening and drain the accumulated rainwater. When the rain sensor detects that rainfall has started, the electric push rod pulls the plug up to close the opening, so that the storage tank begins to accumulate rainwater. The above can all be achieved under existing technical conditions, and will not be described in detail.

[0028] The protective execution module 8 includes a first electric roller 81, a barrier layer 82, a bottom strip 83, a track 84, a traction rope 85, a second electric roller 86, a turning roller 87, a cover 88, and a protruding plate 89. The electric roller is a drive device that houses both the motor and the reducer inside the roller body. The first electric roller 81 is located at the top of the cabinet 1, and a barrier layer 82 is wound around it. A bottom strip 83 is fixedly installed on the side of the barrier layer 82 away from the first electric roller 81. Tracks 84 are symmetrically arranged inside the cabinet 1, and the bottom strip 83 slides within the tracks 84. A second electric roller 86 is located above the partition 4, and a traction rope 85 is wound around it. The end of the traction rope 85 away from the second electric roller 86 is fixedly connected to the bottom strip 83. (Reference) Figure 6 As shown, the traction rope 85 and the cover 88 are specifically fixed in such a way that the traction rope 85 passes through the cover 88, and the cover 88 is fixed to the traction rope 85 in an embedded manner. A turning roller 87 is fixedly installed on the partition 4, and the traction rope 85 changes direction by 90 degrees through the turning roller 87. The cover 88 is fixedly installed on the traction rope 85, and the cover 88 slides with the inner heat dissipation groove 41. A protruding plate 89 is fixedly installed on the bottom strip 83, and the protruding plate 89 cooperates with the circuit breaker 9.

[0029] In the protection execution module 8, when the protection sensing module 7 is triggered by the rain sensor, it drives the second electric roller 86 to rotate, thereby causing the traction rope 85 to wind onto the second electric roller 86. First, in the horizontal direction, the traction rope 85 will drive the cover 88 to slide, blocking the inner heat dissipation groove 41. At the same time, in the vertical direction, the traction rope 85 drags the bottom strip 83 downward, thereby causing the barrier layer 82 to be released and opened relative to the first electric roller 81, forming a barrier between the power distribution control element 6 and the door panel 3. As the rainfall increases, the second electric roller 86 continues to rotate, triggering the emergency protection, that is, the bottom continues to slide down along the track 84, causing the convex plate 89 to toggle the circuit breaker 9, disconnecting the power distribution control element 6 from the external circuit. The first electric roller 81 is then used to reset the above actions after the rainfall stops and the moisture threat disappears.

[0030] The barrier layer 82 is made of highly absorbent fibers. By utilizing highly absorbent fiber materials, the barrier layer 82 not only serves as a barrier but can also actively absorb water to a certain extent, thereby reducing the impact of moisture and improving protective performance.

[0031] The track 84 is L-shaped with an arc-shaped bend, which is adapted to the sliding motion of the bottom strip 83.

[0032] A sleeve 51 is installed on the bracket 5, and a sliding column 52 is slidably installed in the sleeve 51. The top end of the sliding column 52 is fixedly connected to the bottom of the power distribution control element 6, thereby changing the installation state of the power distribution control element 6 and giving the power distribution control element 6 the characteristic of adjustable height. It should be noted that the sliding column 52 relative to the sleeve 51 is designed with a certain redundancy distance to ensure that when the power distribution control element 6 is raised, the sliding column 52 is raised along with it and will not be suspended in the bracket 5.

[0033] A rotating shaft 801 is rotatably installed in the cabinet 1. A synchronous belt drive device 802 is provided between the rotating shaft 801 and the output end of the second electric roller 86. A gear 803 is fixedly installed at the end of the rotating shaft 801. A rack 804 that cooperates with the gear 803 is fixedly installed on the back side of the power distribution control element 6.

[0034] When the protective execution module 8 is activated, considering the impact of extreme situations (water directly entering the cabinet 1), the rotation output of the second electric roller 86 is transported to the side of the rotating shaft 801 via the synchronous belt drive device 802. The rotation of the rotating shaft 801 drives the gear 803 to rotate, and then meshes with the rack 804, thereby causing the power distribution control element 6 to move upward and be raised, so as to avoid damage caused by direct immersion in water.

[0035] The circuit breaker 9 is provided with a lever 91 for controlling the switch state, and the protruding plate 89 makes contact with the lever 91 when it moves.

[0036] The embodiments of the present invention have been described above. However, the embodiments are not limited to the specific implementation methods described above. The specific implementation methods described above are merely illustrative and not restrictive. Those skilled in the art can make more equivalent embodiments under the guidance of the present embodiments, and all of them are within the protection scope of the present embodiments.
