Description

TECHNICAL FIELD

[0001] The present application relates to the field of power cabinet, especially to a power cabinet waterproof monitoring and processing structure. BACKGROUND

[0002] The power cabinet is a device for providing power distribution and control for electrical equipment, which is generally composed of a cabinet body, various electrical components such as circuit breakers, contactors, relays, fuses, busbars, instruments and connecting wires, etc. It can reasonably distribute input power and supply different branches and equipment according to demand, and has overload, short circuit and other protection functions to ensure safe and stable power supply. It is widely used in power distribution systems of industrial, commercial buildings, data centers and other places.

[0003] The prior art part of the power cabinet is an outdoor power cabinet. In order to maintain the internal temperature stable during the use of the power cabinet, a ventilation opening is usually provided on the power cabinet. When it rains, rainwater may enter the power cabinet through the ventilation opening. If accompanied by strong wind at the same time, the rainwater will be driven to tilt towards the ventilation opening, resulting in a large amount of rainwater entering the power cabinet, affecting the use of the power cabinet, and even causing safety hazards. SUMMARY

[0004] The purpose of the present application is to solve the problems existing in the prior art and provide a power cabinet waterproof monitoring and processing structure.

[0005] The present application provides a power cabinet waterproof monitoring and processing structure, which comprises a protective cabinet body provided with a cabinet door, and further comprises:

[0006] A plurality of ventilation openings are provided on the side wall of the protective cabinet body;

[0007] A waterproof ventilation assembly is installed inside the ventilation opening and adjusts the angle of the air inlet to prevent water;

[0008] A monitoring bin is arranged at the bottom of the inside of the protective cabinet body;

[0009] A through opening is provided at the top of the monitoring bin to connect the monitoring bin with the inside of the protective cabinet body;

[0010] A plugging assembly is installed inside the ventilation opening and is used to plug the corresponding ventilation opening with the waterproof ventilation assembly according to the wind direction when strong wind occurs during rain;

[0011] A rainwater detector is installed at the top of the cabinet door to monitor the rainfall;

[0012] The inside of the protection cabinet body is provided with the internal structure of the power supply cabinet. The ventilation opening is used for ventilating the inside of the protection cabinet body. If rainwater seeps into the inside of the protection cabinet body, the seeped rainwater enters the inside of the monitoring bin through the ventilation opening, thereby facilitating the avoidance of water accumulation in the inside of the protection cabinet body;

[0013] The waterproof ventilation assembly arranged in the ventilation opening adjusts the ventilation direction of the ventilation opening. When the rainwater is inclined under the action of strong wind, the inclined rainwater will not be directed to the ventilation direction of the ventilation opening adjusted by the waterproof ventilation assembly, thereby facilitating the blocking of the inclined rainwater and the avoidance of the entry of rainwater.

[0014] In addition, in a strong wind environment, if the rainfall increases, the strong wind is directed to the corresponding ventilation opening. At this time, the plugging assembly is triggered under the action of the strong wind, and the plugging assembly plugs the corresponding ventilation opening, thereby avoiding the entry of rainwater into the plugged ventilation opening directed to the wind direction.

[0015] The rainwater detector can adjust the rainfall state, thereby facilitating the timely identification of the rainfall state.

[0016] Preferably, the waterproof ventilation assembly comprises:

[0017] A plurality of grid plates, the plurality of grid plates are a group, and the grid plates in the group are fixedly installed in the inside of the ventilation opening in a vertical linear array;

[0018] A plurality of curved plates, one end of the curved plate towards the outside of the protection cabinet body is in a flat state, the other end is in an arc state, and the arc end is bent upwards, and an airflow passage is left between the top of the arc end and the upper grid plate or the ventilation opening side wall;

[0019] The inclined grid plate can preliminarily adjust the ventilation direction of the ventilation opening, thereby facilitating the avoidance of the entry of rainwater due to the ventilation direction being directed to the rainfall direction. The curved plate is arranged, so that when the airflow drives the rainwater to enter along the curved plate, the arc end of the curved plate is curled upwards, so that the airflow flowing along the curved plate and the carried rainwater are blocked by the arc. When flowing along the arc, the airflow and the carried rainwater are diverted, thereby facilitating the diversion of the airflow and the carried rainwater to be discharged outward, thereby facilitating the blocking of rainwater when the airflow is relatively weak.

[0020] Preferably, the plugging assembly comprises:

[0021] A plurality of air bags are respectively fixed to the top of each grid plate;

[0022] A plurality of groups of guide pipes, a plurality of the guide pipes being a group, the guide pipes in the same group being linearly arranged on the top of the same grid plate, one end of the guide pipes being a horn opening towards the outside of the protective cabinet, the other end being towards the air bag;

[0023] A plurality of groups of openings, a plurality of the guide pipes being a group, the openings in the same group being linearly arranged on the sidewall of the same air bag, each of the guide pipes being in communication with each of the openings;

[0024] When there is strong wind, the strong wind is towards the air vent, the airflow passes through the openings into the inside of the air bag along the guide pipes, so that the air bag is inflated, so that the inside of the air vent towards the airflow direction is blocked by the inflated air bag, thereby blocking and intercepting the rainwater from entering.

[0025] Preferably, the blocking assembly comprises:

[0026] A plurality of first magnet pieces are respectively installed on each of the air bags;

[0027] A plurality of second magnet pieces are respectively fixed on the bottom of each of the grid plates and the top of the air vent, the first magnet pieces are close to the second magnet pieces to generate magnetic attraction after the air bags are inflated, and the air bags are pulled by the magnetic attraction;

[0028] When the air bag is inflated, the inflated air bag pushes the first magnet piece close to the second magnet piece, so as to be attracted and combined between the first magnet piece and the second magnet piece by magnetic attraction, thereby driving the air bag to block the air vent, thereby facilitating the inflated air bag to play a blocking and intercepting role, thereby avoiding the entry of rainwater.

[0029] Preferably, it further comprises:

[0030] A rain amount monitor is installed in the inside of the monitoring bin for monitoring the accumulated water in the inside of the monitoring bin;

[0031] An alarm is installed in the inside of the protective cabinet for alarming when the rain amount monitor monitors that the accumulated water reaches a specified position;

[0032] The rain amount monitor can detect the amount of accumulated water in the monitoring bin, when it is detected that the accumulated water in the inside of the monitoring bin reaches a specified position, it indicates that the rainfall is large and the accumulated water starts, at this time, the alarm is triggered to alarm, thereby prompting the staff, and the controller can also send a warning to the staff to prompt the staff to take emergency protection measures.

[0033] Preferably, it further comprises:

[0034] A water pump is fixed in the inside of the monitoring bin;

[0035] A drain pipe connects the output end of the water pump to the outside of the protective cabinet.

[0036] The water inlet pipe connects the input end of the water pump to the interior of the monitoring chamber;

[0037] When the accumulated water reaches the designated position, the water pump is activated. After the water pump is activated, it draws out the rainwater inside the monitoring chamber through the inlet and outlet pipes and discharges it to the outside of the protective cabinet, thereby preventing rainwater from accumulating inside the protective cabinet and causing damage.

[0038] Preferably, it further includes:

[0039] Two first delivery pipes are each connected to the drain pipe at one end;

[0040] Several water bladders are respectively installed between the air bladder and the first magnet plate;

[0041] Several connecting pieces, each with a through groove inside, are respectively connected to the other end of the first delivery pipe and each of the water bags;

[0042] The first control valve is installed inside the drain pipe;

[0043] Two second control valves are respectively installed inside the two first delivery pipes;

[0044] When the water pump starts, the first control valve is closed and the second control valve is opened. The water pump delivers water along the first delivery pipe and then enters the water bladder through the connecting piece, causing the water bladder to expand. The expanded water bladder can stably block the vent. After the water bladder is full of water and the vent is blocked, the first control valve is opened and the second control valve is closed to drain the excess water.

[0045] Preferably, it further includes:

[0046] Multiple built-in water bladders are fixed to the inner wall of the protective cabinet. After all the built-in water bladders are inflated, they will squeeze and block the inner wall of the protective cabinet and the seam with the cabinet door.

[0047] Multiple second delivery pipes are respectively connected to each of the built-in water bladders and the nearest first delivery pipe;

[0048] Multiple third control valves are fixed inside each of the second delivery pipes;

[0049] When the third control valve is open and the first and second control valves are closed, the water pumped by the water pump can only enter the interior of the built-in water bladder. This causes the built-in water bladder to expand and squeeze and block the inner wall of the protective cabinet and the joint with the cabinet door, thereby preventing external water from entering the interior of the protective cabinet through the joint and causing damage to the internal equipment.

[0050] Preferably, it further includes:

[0051] The water bladder is inclined, with one end at the bottom connected to the connecting piece;

[0052] The water bladder is tilted so that when the water pump is turned off and the first control valve and the second control valve are opened, the water inside the water bladder can be discharged along the first delivery pipe and the drain pipe, thereby restoring ventilation to the vent.

[0053] Preferably, it further includes:

[0054] A pressure sensor is installed inside the drain pipe. In the initial state, the first control valve and the third control valve are closed, and the second control valve is open. When the pressure sensor detects that the pressure reaches a first specified value, the first control valve is closed, and the second control valve and the third control valve are open. When the pressure sensor detects that the pressure reaches a second specified value, the first control valve is open, and the second control valve and the third control valve are closed.

[0055] The pressure sensor can identify the state of water delivery. After the water bladder is filled with water, the pressure sensor detects that the pressure has reached a first specified value, which causes the water to be delivered to the inside of the water bladder through the control valve. After the water bladder is filled with water, the pressure sensor detects that the pressure has reached a second specified value, which causes the excess water to be discharged through the control valve.

[0056] Compared with the prior art, the present invention has the following beneficial effects:

[0057] By installing waterproof ventilation components, the ventilation direction of the vents can be adjusted. This prevents rainwater from tilting under strong winds and instead flowing in the direction adjusted by the waterproof ventilation components. This helps to block the tilted rainwater and prevent it from entering. Attached Figure Description

[0066] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0067] like Figures 1 to 7 The power cabinet waterproof monitoring and treatment structure shown includes a protective cabinet 1, which is provided with a cabinet door 101, and also includes:

[0068] Multiple ventilation openings 102 are provided on the side wall of the protective cabinet 1;

[0069] A waterproof ventilation component is installed inside the ventilation opening 102, and waterproofing is achieved by adjusting the angle of the air inlet.

[0070] Monitoring compartment 103 is located at the bottom of the interior of protective cabinet 1;

[0071] The opening 104 is located at the top of the monitoring chamber 103 to connect the monitoring chamber 103 with the interior of the protective cabinet 1;

[0072] The sealing component is installed inside the vent 102 and is used to seal the corresponding vent 102 in conjunction with the waterproof ventilation component when strong winds occur during rainfall, according to the wind direction.

[0073] A rainwater detector is installed on the top of cabinet door 101 to monitor rainfall;

[0074] In the existing technology, some power cabinets are outdoor power cabinets. In order to maintain the internal temperature stability during the use of the power cabinet, ventilation openings are usually installed on the power cabinet. However, during rainfall, rainwater may enter the power cabinet through the ventilation openings. If strong winds are present at the same time, the rain will be driven to tilt towards the ventilation openings, resulting in a large amount of rainwater entering, affecting the use of the power cabinet, and even causing safety hazards.

[0075] This embodiment of the present invention can solve the above problems. The specific implementation method is as follows: the internal structure of the power cabinet is installed inside the protective cabinet 1. The ventilation port 102 is used to ventilate the inside of the protective cabinet 1. If rainwater seeps into the inside of the protective cabinet 1, the seeping rainwater enters the monitoring chamber 103 through the opening 104, which helps to avoid the situation of rainwater accumulating inside the protective cabinet 1.

[0076] The waterproof ventilation component installed inside the vent 102 adjusts the ventilation direction of the vent 102, so that when rainwater is tilted under the action of strong wind, the tilted rainwater will not be directed towards the ventilation direction of the vent 102 after the waterproof ventilation component is adjusted, thus helping to block the tilted rainwater and prevent rainwater from entering.

[0077] Furthermore, in strong wind conditions, if the rainfall increases and the strong wind is directed towards the corresponding ventilation opening 102, the sealing component will be triggered under the action of the strong wind. The sealing component will block the corresponding ventilation opening 102, thereby preventing rainwater from entering after the ventilation opening 102 facing the wind direction is blocked.

[0078] Rainwater detectors can adjust to rainfall patterns, which helps to identify rainfall conditions in a timely manner.

[0079] As an optional embodiment, the waterproof ventilation component includes:

[0080] Several grid plates 2, multiple grid plates 2 are grouped together, and a group of grid plates 2 are fixedly installed in a vertical linear array inside the ventilation opening 102;

[0081] Several curved plates 201, one end of the curved plate 201 facing the outside of the protective cabinet 1 is straight, and the other end is arc-shaped, with the arc-shaped end curving upward. An airflow channel is left between the top of the arc-shaped end and the upper grid plate 2 or the side wall of the upper ventilation opening 102.

[0082] The inclined grid plate 2 can initially adjust the ventilation direction of the vent 102, thereby helping to prevent rainwater from entering due to the ventilation direction being towards the direction of rainfall. The curved plate 201 causes the curved end of the curved plate 201 to curl upwards when the airflow carries rainwater in along the curved plate 201. This causes the airflow and the rainwater carried along the curved plate 201 to be blocked by the arc, and to turn in the direction of the arc. This helps to guide the airflow and the rainwater carried to turn outwards and discharge, thus helping to block rainwater when the airflow is relatively weak.

[0083] As an optional embodiment, the blocking component includes:

[0084] Several airbags 3 are fixed to the top of each grid plate 2;

[0085] Several groups of guide pipes 301, multiple guide pipes 301 are grouped together, and the guide pipes 301 in the same group are arranged in a linear array on the top of the same grid plate 2. One end of the guide pipe 301 facing the outside of the protective cabinet 1 has a flared opening, and the other end faces the airbag 3.

[0086] Several sets of openings 302 and multiple guide pipes 301 are grouped together. The openings 302 in the same group are arranged in a linear array on the side wall of the same airbag 3, and each guide pipe 301 is connected to each opening 302.

[0087] When there is a strong wind, and the strong wind is directed towards the vent 102, the airflow passes through the opening 302 along the guide pipe 301 and enters the interior of the airbag 3, causing the airbag 3 to inflate. As a result, the vent 102 facing the airflow direction is blocked by the inflated airbag 3, thereby blocking and intercepting rainwater and preventing rainwater from entering.

[0088] As an optional embodiment, the blocking component includes:

[0089] Several first magnet pieces 401 are respectively installed on each airbag 3;

[0090] Several second magnet pieces 402 are fixed to the bottom of each grid plate 2 and the top of the vent 102 respectively. After the airbag 3 is inflated, the first magnet piece 401 approaches the second magnet piece 402 and is magnetically attracted. When in use, the airbag 3 is pulled by magnetic attraction.

[0091] When the airbag 3 inflates, the inflated airbag 3 pushes the first magnet 401 closer to the second magnet 402, thereby attracting and adhering to the second magnet 402 through magnetic attraction. This causes the airbag 3 to block the ventilation opening 102, which helps the inflated airbag 3 to play a blocking and intercepting role, thus preventing rainwater from entering.

[0092] As an optional embodiment, it also includes:

[0093] A rainfall monitor is installed inside the monitoring chamber 103 to monitor the water accumulation inside the monitoring chamber 103;

[0094] An alarm device is installed inside the protective cabinet 1 to trigger an alarm when the rain gauge detects that water has reached a designated location.

[0095] The rainfall monitor can detect the amount of water accumulated in the monitoring chamber 103. When the water inside the monitoring chamber 103 reaches the designated position, it indicates that the rainfall is heavy and water accumulation has begun. At this time, the alarm is triggered to alert the staff. At the same time, the controller can also issue a warning to the staff to prompt them to take emergency protective measures.

[0096] As an optional embodiment, it also includes:

[0097] Water pump 5 is fixed inside the monitoring chamber 103;

[0098] Drain pipe 501 is connected to the output end of water pump 5 and the outside of protective cabinet 1;

[0099] The water inlet pipe 502 is connected to the input end of the water pump 5 and the interior of the monitoring chamber 103;

[0100] When the accumulated water reaches the designated position, the water pump 5 is started. After the water pump 5 is started, the rainwater inside the monitoring chamber 103 is pumped out through the water inlet pipe 502 and the drain pipe 501 and discharged to the outside of the protective cabinet 1, thereby avoiding the accumulation of rainwater inside the protective cabinet 1 and causing damage.

[0101] As an optional embodiment, it also includes:

[0102] Two first conveying pipes 6 are each connected to a drain pipe 501 through one end;

[0103] Several water bladders 602 are respectively installed between the air bladder 3 and the first magnetic piece 401;

[0104] Several connecting pieces 601 are provided with through grooves inside, which respectively connect the other end of the first conveying pipe 6 to each water bag 602;

[0105] The first control valve is installed inside the drain pipe 501;

[0106] Two second control valves are respectively installed inside the two first delivery pipes 6;

[0107] When the water pump 5 starts, the first control valve is closed and the second control valve is opened. The water pump 5 delivers water along the first delivery pipe 6 and then enters the water bladder 602 through the connecting piece 601, causing the water bladder 602 to expand. The expanded water bladder 602 can stably block the vent 102. After the water bladder 602 is full of water and the vent 102 is blocked, the first control valve is opened and the second control valve is closed to drain the excess water.

[0108] As an optional embodiment, it also includes:

[0109] Multiple built-in water bladders 7 are fixed to the inner wall of the protective cabinet 1. After all the built-in water bladders 7 are inflated, they squeeze and block the inner wall of the protective cabinet 1 and the joint with the cabinet door 101.

[0110] Multiple second delivery pipes 701 are respectively connected to each built-in water bladder 7 and the nearest first delivery pipe 6;

[0111] Multiple third control valves are fixed inside each of the second delivery pipes 701;

[0112] When the third control valve is open and the first and second control valves are closed, the water pumped by the pump 5 can only enter the interior of the built-in water bladder 7. This causes the built-in water bladder 7 to expand and squeeze and block the inner wall of the protective cabinet 1 and the joint with the cabinet door 101, thereby preventing external water from entering the interior of the protective cabinet 1 through the joint and causing damage to the internal equipment.

[0113] As an optional embodiment, it also includes:

[0114] The water bladder 602 is inclined, with one end at the bottom connected to the connecting piece 601;

[0115] The water bladder 602 is tilted so that when the water pump 5 is turned off and the first control valve and the second control valve are turned on, the water inside the water bladder 602 can be discharged along the first delivery pipe 6 and the drain pipe 501, thereby restoring ventilation of the vent 102.

[0116] As an optional embodiment, it also includes:

[0117] The pressure sensor is installed inside the drain pipe 501. In the initial state, the first control valve and the third control valve are closed, and the second control valve is open. When the pressure sensor detects that the pressure reaches the first specified value, the first control valve is closed, and the second control valve and the third control valve are open. When the pressure sensor detects that the pressure reaches the second specified value, the first control valve is open, and the second control valve and the third control valve are closed.

[0118] The pressure sensor can identify the state of water delivery. After the water bladder 602 is filled with water, the pressure sensor detects that the pressure has reached the first specified value, so that the water is delivered to the inside of the built-in water bladder 7 by controlling the valve. After the built-in water bladder 7 is filled with water, the pressure sensor detects that the pressure has reached the second specified value, so that the excess water is discharged by controlling the valve.

[0119] Working principle of the invention: The internal structure of the power cabinet is installed inside the protective cabinet 1. The ventilation port 102 is used to ventilate the inside of the protective cabinet 1. If rainwater seeps into the inside of the protective cabinet 1, the seeping rainwater enters the monitoring chamber 103 through the opening 104, which helps to avoid the situation of rainwater accumulating inside the protective cabinet 1.

[0120] The waterproof ventilation component installed inside the vent 102 adjusts the ventilation direction of the vent 102, so that when rainwater is tilted under the action of strong wind, the tilted rainwater will not be directed towards the ventilation direction of the vent 102 after the waterproof ventilation component is adjusted, thus helping to block the tilted rainwater and prevent rainwater from entering.

[0121] Furthermore, in strong wind conditions, if the rainfall increases and the strong wind is directed towards the corresponding ventilation opening 102, the sealing component will be triggered under the action of the strong wind. The sealing component will block the corresponding ventilation opening 102, thereby preventing rainwater from entering after the ventilation opening 102 facing the wind direction is blocked.

[0122] Rainwater detectors can adjust to rainfall patterns, which helps to identify rainfall conditions in a timely manner.

[0123] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
