Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of power distribution facilities, more particularly, it relates to an integrated power distribution control cabinet. BACKGROUND

[0002] The power distribution control cabinet is a key infrastructure in power transmission and distribution, industrial automation, communication base station and other aspects, and precise and expensive power distribution control elements such as circuit breakers, contactors, PLCs and frequency converters are usually installed inside the cabinet. The safe and stable operation of these elements is crucial to the reliability of the entire system.

[0003] At present, one of the main threats to outdoor power distribution control cabinets is the intrusion of liquid water (rainwater). Although existing standards (IP protection level) require the cabinet body itself to have certain waterproof performance (IPX4 splash-proof, IPX5 spray-proof, etc.), in actual application, especially in persistent heavy rain, typhoon or extreme weather conditions, there are still the following significant risks:

[0004] Seal aging: components such as door sealing strips and threading hole sealing sleeves will age and crack over time and with temperature changes, resulting in a decline in sealing performance and an inability to consistently guarantee waterproofing capabilities;

[0005] Influence of ventilation components: to control the temperature inside the cabinet, the cabinet body is usually designed with ventilation louvers, but this is fundamentally incompatible with high-level waterproofing requirements, and rainwater can easily enter from here;

[0006] Extreme weather overruns: existing static protection designs are based on specific test conditions, and when encountering extreme rainfall far exceeding design standards, rainwater can seep in from various gaps.

[0007] Once water intrusion occurs, it can easily cause electrical short circuits, equipment burnout, system downtime and other serious accidents, resulting in economic losses and safety risks.

[0008] The most advanced existing solutions begin to introduce the concept of active protection, such as using humidity sensors to monitor the status inside the cabinet and starting heating and dehumidification when the humidity exceeds the standard, but this solution still reacts after water vapor has entered the cabinet, and for sudden large amounts of liquid water intrusion, the response speed and protection effect are both insufficient. SUMMARY

[0009] The present application provides an integrated power distribution control cabinet, which solves the technical problems of water vapor entering the cabinet and affecting the related technology when water vapor protection is performed, and the slow response speed and poor effect of the related protection mechanism.

[0010] The application provides an integrated power distribution control cabinet, which comprises a cabinet body, a base, a power distribution control element, a protection sensing module, a protection executing module and a circuit breaker, the base is fixedly provided with the cabinet body at the top, a door plate is rotatably installed on the cabinet body, a partition is arranged between the base and the cabinet body, a support is fixedly arranged above the partition, the power distribution control element is slidably arranged above the support, the circuit breaker for controlling the on-off of the power distribution control element and an external circuit is installed on the base, the protection sensing module is installed outside the cabinet body and senses rain variation to drive the protection executing module to operate.

[0011] An outer heat dissipation groove is formed in the base, and an inner heat dissipation groove is formed in the partition and is in communication with the outer heat dissipation groove.

[0012] Driven by the protection sensing module, the protection executing module forms a waterproof blocking surface at the opening of the cabinet body towards the door plate;

[0013] Driven by the protection sensing module, the protection executing module covers and blocks the inner heat dissipation groove;

[0014] Driven by the protection sensing module, the protection executing module actuates the circuit breaker to block the power distribution control element and the external circuit;

[0015] Driven by the protection sensing module, the protection executing module pushes the power distribution control element to move upwards.

[0016] As a further scheme of the application, the protection sensing module comprises a controller, a storage box and a water level sensor, the controller is fixedly installed at the top of the cabinet body and is electrically connected with the protection executing module, the storage box is fixedly installed on one side of the cabinet body, and the water level sensor electrically connected with the controller is matched in the storage box.

[0017] As a further scheme of the application, the protection executing module comprises a first electric roller, a blocking layer, a bottom strip, a track, a traction rope, a second electric roller, a turning roller, a cover and a convex plate, the first electric roller is arranged at the top of the cabinet body, the blocking layer is wound on the first electric roller, the bottom strip is fixedly arranged on the side of the blocking layer away from the first electric roller, the track is symmetrically arranged in the cabinet body and is slidably matched with the bottom strip, the second electric roller is arranged above the partition, the traction rope is wound on the second electric roller, one end of the traction rope away from the second electric roller is fixedly connected with the bottom strip, the turning roller is fixedly installed on the partition, the traction rope is changed by 90 degrees through the turning roller, the cover is fixedly installed on the traction rope, the cover is slidably matched with the inner heat dissipation groove, the convex plate is fixedly installed on the bottom strip and is matched with the circuit breaker.

[0018] As a further scheme of the application, the blocking layer is made of fibers with high water absorption.

[0019] As a further scheme of the present application: the track is L-shaped, and the turning part is circular arc-shaped.

[0020] As a further scheme of the present application: a sleeve is mounted on the support, a sliding column is slidingly mounted in the sleeve, and the top end of the sliding column is fixedly connected with the bottom of the power distribution control element.

[0021] As a further scheme of the present application: a rotating shaft is rotatably mounted in the cabinet, a synchronous belt transmission device is arranged between the rotating shaft and the output end of the second electric roller, a gear is fixedly mounted at the end of the rotating shaft, and a rack that cooperates with the gear is fixedly mounted at the back side of the power distribution control element.

[0022] As a further scheme of the present application: a control switch state is arranged in the circuit breaker, and the convex plate is in extrusion contact with the control switch state when the convex plate moves.

[0023] The present application has the following beneficial effects:

[0024] The present application can perceive and trigger action in advance before rainwater accumulates to a dangerous degree through the rain monitoring mechanism. This active early warning and intervention mode changes the protection node from passive processing after water intrusion to active blocking when water is about to intrude, fundamentally avoiding the contact between liquid water and electrical equipment and realizing real preventive protection.

[0025] The present application links mechanical action (the blocking layer is in place) and electrical safety (the circuit breaker) through the toggle switch, which means that both the establishment of the physical barrier in the normal state and the forced power cut-off of the core circuit in the emergency state are realized. This design eliminates secondary disasters such as short circuit, electric arc, equipment burning, and even fire caused by water intrusion, thereby providing the highest level of safety protection for equipment and personnel.

[0026] When the protection execution module generates action, the rotation output of the second electric roller is transmitted to the rotating shaft side through the synchronous belt transmission device, the rotation of the rotating shaft drives the rotation of the gear, and then the rack is engaged, so that the power distribution control element is lifted upwards, thereby avoiding damage caused by the direct soaking of the power distribution control element in water.

DETAILED DESCRIPTION

[0036] The subject matter described herein will now be discussed with reference to example implementations. It should be understood that discussions of these implementations are intended to serve as examples only and that changes to elements of the examples discussed can be made in light of the teachings provided herein without departing from the scope of the disclosure. Various examples can omit, substitute, or add various procedures or components in addition to those described or in lieu thereof. Also, many modifications can be made to the examples described herein, which have been presented for the purposes of example and illustration only.

[0037] The present application discloses a kind of integrated power distribution control cabinet, such as Figure 1 - Figure 8As shown, including cabinet 1, base 2, power distribution control element 6, protective sensing module 7, protective execution module 8 and circuit breaker 9, the top of the base 2 is fixedly provided with cabinet 1, the door plate 3 is rotatably installed on the cabinet 1, the partition 4 is arranged between the base 2 and the cabinet 1, the bracket 5 is fixedly arranged above the partition 4, the power distribution control element 6 is slidably arranged above the bracket 5, the relative sliding of the slide column 52 and the sleeve 51 is realized, the circuit breaker 9 for controlling the power distribution control element 6 and the external circuit is installed on the base 2, the protective sensing module 7 is installed outside the cabinet 1, and the rain change is sensed to drive the protective execution module 8 to operate;

[0038] 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.

[0039] Driven by the protective sensing module 7, the protective execution module 8 forms a waterproof blocking surface on the opening of the cabinet 1 towards the door plate 3 side;

[0040] Driven by the protective sensing module 7, the protective execution module 8 covers and blocks the inner heat dissipation groove 41;

[0041] Driven by the protective sensing module 7, the protective execution module 8 drives the circuit breaker 9, and the power distribution control element 6 is blocked from the external circuit;

[0042] Driven by the protective sensing module 7, the protective execution module 8 pushes the power distribution control element 6 upwards.

[0043] The core element of the power distribution control cabinet in the heavy rainfall environment is the power distribution control element 6, which provides a progressive moisture protection mechanism, specifically:

[0044] The protective sensing module 7 serves as a trigger site, which monitors the change of rainfall in real time and drives the protective execution module 8 to execute moisture protection;

[0045] The protective execution module 8 is realized based on a moving action, the amplitude of the moving action is positively correlated with the rainfall applied by the external environment, and according to the size of the rainfall, the protective execution can be divided into two states of normal protection and emergency protection, in the normal protection state, the moving action synchronously realizes the blocking of the opening side of the cabinet 1 (to prevent water from pouring into the gap), the plugging of the heat dissipation groove part (to isolate the entry of water) and the lifting of the height of the power distribution control element 6 (to prevent water immersion), in the emergency protection state, the moving action further increases the amplitude, and passes through the position of the circuit breaker 9, so as to drive the circuit breaker 9, and the power distribution control element 6 is blocked from the external circuit, realizing power-off protection.

[0046] The protection sensing module 7 comprises 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 electrically connected with the protection executing module 8. The storage box 72 is fixedly installed on one side of the cabinet 1. The water level sensor 73 is fitted in the storage box 72 and electrically connected with the controller 71.

[0047] When sensing the rainfall, the storage box 72 is used to collect the rainfall. The water level sensor 73 senses the change of the water level in the storage box 72. The controller 71 converts it into the rainfall. Then, the controller 71 drives the protection executing module 8 to operate according to the rainfall.

[0048] It should be specially noted that the storage tank is designed to consider the influence of water storage. After the rainfall stops, the water is actively discharged (the corresponding active discharge structure is not shown) to avoid affecting the subsequent monitoring. The combination of the storage tank and the water level sensor 73 to measure the rainfall can be directly replaced by a rainfall sensor. The principle of the active discharge of the storage tank is that Figure 2 The bottom of the storage tank is provided with an opening. The plug is slidably extended relative to the opening. The electric push rod drives the plug. The electric push rod is matched with the rainfall sensor. When the rainfall sensor detects that the rainfall stops, the electric push rod pushes the plug to move downward to open the opening to discharge the accumulated rainwater. When the rainfall sensor detects that the rainfall starts, the electric push rod pulls the plug to move upward to close the opening so that the storage tank starts to accumulate rainwater. The above can be realized under the existing technical conditions and will not be described.

[0049] The protection executing module 8 comprises a first electric roller 81, a blocking 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 convex plate 89. The electric roller is a driving device in which the motor and the speed reducer are jointly arranged in the roller body. The first electric roller 81 is arranged on the top of the cabinet 1. The blocking layer 82 is arranged on the first electric roller 81. The bottom strip 83 is fixedly arranged on the side of the blocking layer 82 away from the first electric roller 81. The track 84 is symmetrically arranged in the cabinet 1. The bottom strip 83 is slidably matched with the track 84. The second electric roller 86 is arranged above the partition 4. The traction rope 85 is arranged on the second electric roller 86. One end of the traction rope 85 away from the second electric roller 86 is fixedly connected with the bottom strip 83. As shown in Figure 6 The specific fixing form of the traction rope 85 and the cover 88 is that the traction rope 85 penetrates through the cover 88. The cover 88 is fixed on the traction rope 85 in the form of inlay. The turning roller 87 is fixedly installed on the partition 4. The traction rope 85 is turned by 90 degrees through the turning roller 87. The cover 88 is fixedly installed on the traction rope 85. The cover 88 is slidably matched with the inner heat dissipation groove 41. The convex plate 89 is fixedly installed on the bottom strip 83. The convex plate 89 is matched with the circuit breaker 9.

[0050] In the protection execution module 8, when the protection sensing module 7 is triggered by the rain amount sensing, the second electric roller 86 is driven to rotate, so that the traction rope 85 is wound on the second electric roller 86. First, the traction rope 85 will slide the cover 88 in the horizontal direction, and the inner heat dissipation groove 41 is shielded. At the same time, in the vertical direction, the traction rope 85 drags the bottom strip 83 to move downward, so that the blocking layer 82 is released and opened relative to the first electric roller 81, and a barrier is formed between the power distribution control element 6 and the door plate 3. With the increase of the amount of rain, the second electric roller 86 continues to rotate, triggering the emergency protection, that is, the bottom continues to slide along the track 84, so that the convex plate 89 actuates the circuit breaker 9, disconnecting the connection between the power distribution control element 6 and the external circuit, and the first electric roller 81 is used for resetting the above-mentioned action after the rain stops and the moisture threat disappears.

[0051] The blocking layer 82 is made of fibers with high water absorption. The use of high water absorption fiber material enables the blocking layer 82 to not only have the function of barrier and block, but also actively absorb water to a certain extent, thereby reducing the influence of moisture and improving the protection performance.

[0052] The track 84 is L-shaped, and the turning part is circular arc-shaped, which is matched with the sliding action of the bottom strip 83.

[0053] The bracket 5 is provided with a sleeve 51, the sleeve 51 is slidably provided with a slide column 52, the top end of the slide column 52 is fixedly connected with the bottom of the power distribution control element 6, the installation state of the power distribution control element 6 is changed, so that the power distribution control element 6 has the characteristic of adjustable height. It should be specially pointed out that the sliding of the slide column 52 relative to the sleeve 51 is designed to have a certain redundant distance, which can ensure that the slide column 52 is lifted together when the power distribution control element 6 is lifted upward, and will not be suspended in the bracket 5.

[0054] The cabinet 1 is rotatably provided with a rotating shaft 801, the rotating shaft 801 is provided with a synchronous belt transmission device 802 matched with the output end of the second electric roller 86, the end of the rotating shaft 801 is fixedly provided with a gear 803, and the back side of the power distribution control element 6 is fixedly provided with a rack 804 matched with the gear 803.

[0055] When the protection execution module 8 acts, considering the influence of extreme cases (water directly enters the cabinet 1), the rotation output of the second electric roller 86 is transmitted to the side of the rotating shaft 801 through the synchronous belt transmission device 802, the rotation of the rotating shaft 801 drives the gear 803 to rotate, and then engages the rack 804, so that the power distribution control element 6 is lifted upward, avoiding damage caused by the power distribution control element 6 being directly soaked in water.

[0056] The circuit breaker 9 is provided with a switch state control switch 91, and the convex plate 89 moves and is in extrusion contact with the switch 91.

[0057] The above describes the embodiments of the present application, but the embodiments are not limited to the specific implementation described above, which is only illustrative and not restrictive. Those skilled in the art can make more equivalent embodiments under the inspiration of the embodiments, which are all within the protection scope of the embodiments.
