Description

Technical Field

[0001] This application relates to the technical field of power cabinets, and more particularly, to a cabinet structure of an intelligent AC power cabinet. Background Art

[0002] An intelligent power cabinet is a power management device integrating intelligent technologies and functions. Intelligent power cabinets usually feature high efficiency, safety, and reliability, and are widely used in various places where power management and distribution are required. Through the built-in intelligent system, they achieve the monitoring, control, protection, and optimization of power input, thus improving the efficiency and safety of power use. Inside existing intelligent power cabinets, multiple power distribution components and various power distribution devices are usually installed, which generate a large amount of heat during operation. To meet the heat dissipation requirements, heat dissipation slots and cooling fans are usually used to dissipate the heat inside the power cabinet. However, when a fire breaks out due to excessive temperature inside the power cabinet, although the fire extinguishing equipment inside the cabinet will extinguish the fire, the heat dissipation slots will introduce fresh air into the power cabinet, causing the fire to intensify, and the combustion smoke and dust will also spill out to the outside, posing a safety hazard. Therefore, it is necessary to close the heat dissipation openings to prevent fresh air from entering and also prevent the combustion smoke and dust from spilling out. However, this will cause a high-pressure state to form inside the cabinet, presenting a safety hazard.

[0003] Therefore, a cabinet structure of an intelligent AC power cabinet is needed to solve the above problems. Summary of the Invention

[0004] The content part of this application is used to introduce the concepts in a brief form, and these concepts will be described in detail in the subsequent detailed implementation part. The content part of this application is not intended to identify the key features or essential features of the claimed technical solution, nor is it intended to limit the scope of the claimed technical solution.

[0005] In order to solve the technical problems mentioned in the above background technology part, some embodiments of the present application provide an intelligent AC power cabinet structure, including: a power cabinet, a plurality of partition plates are fixed in the power cabinet, the partition plates divide the inner cavity of the power cabinet into a plurality of installation spaces that are not connected to each other, and a sealed door is provided on the power cabinet; a heat dissipation frame is arranged on one side of the power cabinet, and has an air intake hole connected to the installation space, for sucking out the hot air in the installation space; a heat dissipation fan is fixed on the heat dissipation frame, and the air inlet end of the heat dissipation fan is connected to the air intake hole through a pipe; a heat dissipation trough is provided on a side wall of the installation space, and is arranged opposite to the heat dissipation frame, for introducing external cold air into the installation space for cooling; a mounting plate is fixed on the power cabinet, located on one side of the heat dissipation trough, and an annular airbag is provided on the mounting plate, and the annular airbag is arranged around the outer circumference of the heat dissipation trough, for fitting the side of the power cabinet to close the heat dissipation trough; a fire extinguishing component is used to extinguish fire in the cabinet; a sealing component is used to seal the installation space; a heat dissipation frame is provided with a The exhaust gas fan of the present invention is connected with the exhaust gas fan of the present invention in an off-take manner, and the exhaust gas fan of the present invention is connected with the exhaust gas fan of the present invention in an off-take manner.

[0006] With multiple installation spaces provided, when a fire breaks out in one installation space, it does not affect the operation of the equipment in other installation spaces. Through the provided heat dissipation slots and air suction holes, when heat dissipation is required, the hot air in the installation space is extracted through the air suction holes while the cold air enters the installation space through the heat dissipation slots for heat dissipation. Through the provided mounting plate and annular airbag, when it is necessary to seal the installation space during a fire, the annular airbag expands and adheres to one side of the power cabinet body, and cooperates with the mounting plate to close the heat dissipation slots, realizing the sealing of the installation space; through the provided baffle plate, when a fire breaks out in the installation space, the baffle plate blocks the air suction holes and the connecting pipe, preventing the combustion soot in the installation space from being discharged along with the operation of the heat dissipation fan. At the same time, through the provided first impeller and second impeller, the air containing soot is extracted into the annular airbag, avoiding potential hazards caused by the formation of high pressure due to combustion in the installation space body. Through the provided heat insulation cavity, when there is positive pressure in the installation space, the first impeller can rotate synchronously with the second impeller, so that the air in the heat insulation cavity is extracted and flows through the second channel, cooling the partition plate to prevent the temperature of the adjacent installation space from rising due to the excessive temperature caused by the fire in the installation space.

[0007] Furthermore, a mounting frame is fixedly connected in the air suction channel between the connection position of the connecting pipe and the second channel. A first electromagnet is fixedly connected to the mounting frame. The first electromagnet is used to attract the baffle plate. A first spring is arranged between the baffle plate and the mounting frame. A limiting groove is formed on the side wall of the air suction channel between the connection position of the connecting pipe and the first channel. A limiting block for limiting the baffle plate is arranged in the limiting groove. A second magnet is fixedly connected in the limiting groove. The second magnet is used to attract the limiting block. A second spring is further arranged between the limiting block and the inner wall of the limiting groove.

[0008] Through the provided first electromagnet and second electromagnet, when a fire breaks out in the installation space, both the first electromagnet and the second electromagnet are powered off. Under the action of the first spring, the baffle plate moves to the position between the connection position of the connecting pipe and the first channel. At this time, the soot-containing gas inhaled into the air suction channel from the air suction hole is inhaled into the first channel and discharged into the annular airbag through the waste gas pipe, avoiding the direct discharge of the soot-containing gas. When the second electromagnet is powered off, the limiting block can limit the baffle plate, thereby ensuring that the connection position of the connecting pipe is separated from the air suction hole. At the same time, the limiting block has an inclined surface.

[0009] Furthermore, the fire extinguishing assembly includes: an inert gas cylinder fixed on the connecting block. An air outlet head is fixedly arranged on the upper end wall of the installation space. The air outlet end of the inert gas cylinder is communicated with the air outlet head through a connecting structure. The air outlet head is used to introduce inert gas into the installation space for fire extinguishing.

[0010] Through the provided air outlet head and inert gas cylinder, when a fire occurs, inert gas can be filled into the installation space through the inert gas cylinder for fire extinguishing.

[0011] Further, the connection structure includes: a communication pipe connected to the gas outlet of the inert gas cylinder and connected to the gas outlet head, a rotating disk rotatably arranged in the connection block, one end of each of the two communication pipes abuts against both sides of the rotating disk, a through hole for connecting the gas outlet of the inert gas cylinder and the gas outlet head is arranged on the rotating disk, a pulling rope block is fixedly connected to the rotating disk, a pulling rope is connected to the pulling rope block, and one end of the pulling rope is connected to the baffle plate.

[0012] Through the arranged communication pipe and rotating disk, when the dust-containing waste gas in the installation space enters the annular airbag, the baffle plate gradually moves to the position between the air suction port and the first channel, thereby pulling the pulling rope, driving the rotating disk to rotate, and further enabling the through hole to rotate to the position where the gas outlet of the inert gas cylinder and the gas outlet head are connected, discharging inert gas into the installation space. When the inert gas enters the installation space, the air pressure in the installation space changes, causing the baffle plate to move back to the position between the connection position of the communication pipe and the first channel, and at this time, the inert gas stops entering until the baffle plate is located between the air suction port and the first channel again, realizing the repeated introduction of inert gas into the installation space and avoiding excessive use of inert gas.

[0013] Further, the sealing assembly includes: a sealing block fixed on one side of the annular airbag, a sealing groove for the sealing block to be embedded is opened on the side wall of the power cabinet body close to the annular airbag, two rubber protrusions are movably arranged on the sealing block, and depressions for the rubber protrusions to be embedded are opened on the side wall of the sealing groove.

[0014] Through the arranged sealing block and rubber protrusions, when the sealing block is embedded into the sealing groove, the limiting protrusions are also embedded into the depressions, ensuring the sealing effect.

[0015] Further, a heat-conducting block with one end extending into the annular airbag is fixedly connected in the sealing block, a thermosensitive spring in contact with the heat-conducting block is fixedly connected in the sealing block, and one end of the thermosensitive spring abuts against the rubber protrusion for pushing the rubber protrusion into the depression.

[0016] Through the arranged heat-conducting block, since the air containing dust is at a relatively high temperature under the action of combustion, the thermosensitive spring elongates, and then pushes the rubber protrusion into the depression, ensuring the sealing.

[0017] Further, the transmission structure includes a transmission shaft rotatably arranged in the connection block, a first cone wheel is fixedly connected to the second impeller, a second cone wheel meshing with the first cone wheel is fixedly connected to the transmission shaft, and a transmission belt is connected between the first impeller and the transmission shaft.

[0018] Through the arranged transmission structure, the first impeller and the second impeller rotate synchronously.

[0019] Furthermore, a smoke sensor is provided in the installation space, and a controller is provided in the power cabinet body. The controller is used to receive the smoke sensor signal and control the first electromagnet and the second electromagnet.

[0020] The beneficial effects of this application are as follows:

[0021] 1. Through the provided heat dissipation slots and suction holes, when heat dissipation is required, the hot air in the installation space is extracted through the suction holes while the cold air enters the installation space through the heat dissipation slots for heat dissipation. Through the provided mounting plate and annular airbag, when a fire breaks out in the installation space and sealing is required, the annular airbag expands and fits against one side of the power cabinet body, and cooperates with the mounting plate to close the heat dissipation slots, realizing the sealing of the installation space.

[0022] 2. Through the provided baffle plate, when a fire breaks out in the installation space, the baffle plate blocks the suction holes and the connecting pipes, preventing the combustion soot in the installation space from being discharged along with the operation of the heat dissipation fan. At the same time, through the provided first impeller and second impeller, the air containing soot is extracted into the annular airbag, avoiding potential hazards caused by the formation of a high-pressure state due to combustion in the installation space body.

[0023] 3. Through the provided heat insulation cavity, when there is positive pressure in the installation space, the first impeller can rotate synchronously with the second impeller, so that the air in the heat insulation cavity is extracted and flows through the second channel, cooling the partition board to prevent the temperature of the adjacent installation space from rising due to the excessive temperature caused by the fire in the installation space.

[0044] The present disclosure will be described in detail below with reference to the drawings and in combination with the embodiments.

[0045] Refer to Figure 1-11, an intelligent AC power cabinet body structure, comprising: a power cabinet body 100, a partition board 101, a sealing door 102, a heat dissipation frame 103, an air intake hole 104, a heat dissipation fan 105, a heat dissipation groove 106, a mounting plate 107, a circular airbag, a connecting block 109, a connecting pipe 110, a first channel 111, and a second channel 112. Two partition boards 101 are fixed inside the power cabinet body 100, and the two partition boards 101 divide the inner cavity of the power cabinet body 100 into three non-communicating installation spaces 113. The installation spaces 113 are sealed by the sealing door 102, so that the installation spaces 113 dissipate heat through the heat dissipation grooves 106. In one embodiment, to ensure the heat dissipation effect, the heat dissipation frame 103 is fixedly arranged on one side of the power cabinet body 100, and at the same time, the heat dissipation frame 103 is provided with an air intake hole 104 communicating with the installation space 113. A heat dissipation groove 106 is formed on one side wall of the installation space 113, and the heat dissipation groove 106 is arranged opposite to the air intake hole 104. When the air intake hole 104 sucks air, cold air enters the installation space 113 through the heat dissipation groove 106. A heat dissipation fan 105 is fixedly connected to the heat dissipation frame 103, and the air intake end of the heat dissipation fan 105 is communicated with the air intake hole 104 through a pipeline. In one embodiment, when a fire breaks out in one of the installation spaces 113, it is necessary to close the installation space 113 to prevent oxygen from continuously entering. A mounting plate 107 located on one side of the heat dissipation groove 106 is fixedly connected to the power cabinet body 100, and a circular airbag 108 is fixedly connected to the mounting plate 107. The circular airbag 108 is wound around the outer periphery of the heat dissipation groove 106. During heat dissipation, the circular airbag 108 does not expand, and air enters the heat dissipation groove 106 from the gap between the mounting plate 107 and the power cabinet body 100. When it is necessary to close, the circular airbag 108 expands, and one side fits against the side of the power cabinet body 100, cooperating with the mounting plate 107 to close the heat dissipation groove 106, thereby achieving sealing.

[0046] To detect whether a seal has been achieved, in one embodiment, a connection block 109 is fixedly installed within the heat dissipation frame 103, corresponding to the installation space 113. An extraction channel connected to the air intake hole 104 is provided within the connection block 109. The air intake end of the heat dissipation fan 105 is connected to the extraction channel via a connecting pipe 110. When the heat dissipation fan is activated, a negative pressure is formed within the extraction channel, thereby extracting air from the installation space 113. A baffle 115 is slidably connected within the extraction channel to separate the air intake hole 104 from the connecting pipe 110. Furthermore, a first channel 111 and a second channel 112 are provided within the connection block 109. The connection between the first channel 111 and the extraction channel is located between the air intake hole and the connecting pipe 110. A one-way valve 116 is provided at the connection between the first channel 111 and the extraction channel, allowing one-way flow of air from the extraction chamber to the first channel 111. The connection between the second channel 112 and the extraction channel is located on one side of the connecting pipe 110. A first impeller 117 and a second impeller 143 are rotatably connected within the connecting block 109, located at the first channel 111 and the second channel 112, respectively. The first impeller 117 and the second impeller 143 are connected by a transmission structure. The first impeller 117 rotates to cause airflow within the first channel 111, while the second impeller 143 rotates in response to the airflow within the second channel 112. When the baffle 115 is positioned between the second channel 112 and the connecting pipe 110, air within the installation space 113 enters the extraction channel through the air intake vent 104 and is then blown out by the cooling fan 105 through the connecting pipe 110, dissipating heat. When the baffle 115 is positioned between the first channel 111 and the air intake vent 104, the one-way valve 116 prevents the first impeller 117 from rotating, and the second impeller 143 also does not rotate. If the installation space 113 is not completely sealed, the baffle 115 will slide under the influence of air pressure until the first channel 111 is connected to the air intake vent 104. At this time, the first impeller 117 can rotate, and the second impeller 143 can also rotate. At this time, under the action of the negative pressure in the extraction channel, the second impeller 143 rotates, which in turn drives the first impeller 117 to rotate, thereby discharging the gas in the installation space 113 through the first channel 111. To strengthen the seal, the first channel 111 is connected to the exhaust pipe 145, and one end of the exhaust pipe 145 is connected to the annular airbag 108. The second channel 112 is opened in the connecting block 109 and communicates with the exhaust channel 114. A serpentine-shaped insulation cavity 144 is provided in the partition. The second channel 112 is connected to the insulation cavity 144 through a pipe, and the other end of the insulation cavity 114 is connected to the outside world. When the second impeller 143 rotates, it drives the air circulation in the insulation cavity 144, preventing the temperature of the adjacent installation space 113 from rising.

[0047] When installation space 113 is sealed, air within installation space 113 is drawn into annular airbag 108, causing it to expand and seal. Annular airbag 108 is connected to an external airbag via a constant pressure valve. When the air pressure in annular airbag 108 reaches the threshold of the constant pressure valve, air is exhausted to the outside airbag. When installation space 113 is sealed, baffle 115 returns to the space between air intake port 104 and first channel 111, sealing installation space 113.

[0048] At the same time, the exhaust gas containing smoke and dust in the installation space 113 also enters the annular airbag 108 to prevent the smoke and dust from overflowing.

[0049] A mounting bracket 118 is fixedly connected in the air intake passage, located between the connection position of the connecting pipe 110 and the second passage 112. A first electromagnet 119 is fixedly connected to the mounting bracket 118. The first electromagnet 119 is used to attract the baffle 115. A first spring 120 is provided between the baffle 115 and the mounting bracket 118. The two ends of the first spring 120 are respectively fixed to the baffle 115 and the mounting bracket 118. A limiting groove 121 is provided on the side wall of the air intake passage, located between the connection position of the connecting pipe 110 and the first passage 111. A limiting block 122 is provided in the limiting groove 121 for limiting the position of the baffle 115. A second magnet 123 is fixedly connected in the limiting groove 121. The second magnet 123 is used to attract the limiting block 122. A second spring 124 is further provided between the limiting block 122 and the inner wall of the limiting groove 121. The second spring 124 is respectively fixedly connected to the limiting block 122 and the inner wall of the limiting groove 121. A smoke sensor 125 is also installed in the installation space 113, and a controller is installed in the power supply cabinet 100. The controller is used to receive signals from the smoke sensor 125 and control the first and second electromagnets 119. When a fire occurs in one of the installation spaces 113, the smoke sensor 125 detects the signal and transmits it to the control center. The control center de-energizes the first and second electromagnets 119, causing the baffle 115, under the action of the spring, to slide from between the connecting tube 110 and the second channel 112 to between the first channel 111 and the connecting tube 110. At this time, the first channel 111 can draw air from the air intake hole 104. When the first spring 120 is unloaded, the baffle 115 is located between the first channel 111 and the connecting rod.

[0050] A transmission shaft 126 is rotatably connected in the connecting block 109 , a first cone wheel 127 is fixedly connected to the second impeller, a second cone wheel 128 meshing with the first cone wheel 127 is fixedly connected to the transmission shaft 126 , and a transmission belt 129 is connected between the first impeller 117 and the transmission shaft 126 .

[0051] To ensure the sealing effect, a sealing block 130 is fixed on one side of the annular airbag 108. A sealing groove 131 for the sealing block 130 to be embedded is formed on the side wall of the power cabinet body 100 close to the annular airbag 108. Two rubber protrusions 132 are movably arranged on the sealing block 130, and the connection part between the sealing block 130 and the rubber protrusions 132 is made of rubber material. A depression 133 for the rubber protrusions 132 to be embedded is formed on the side wall of the sealing groove 131. A heat-conducting block 134 with one end extending into the annular airbag 108 is fixedly connected inside the sealing block 130. A thermosensitive spring 135 in contact with the heat-conducting block 134 is fixedly connected inside the sealing block 130. One end of the thermosensitive spring 135 abuts against the rubber protrusion 132 and is used to push the rubber protrusion 132 into the depression 133. Since the temperature of the smoke-containing air entering the annular airbag 108 is relatively high, the thermosensitive spring 135 expands, and then pushes the rubber protrusion 132 to the depression 133, ensuring the sealing effect.

[0052] To ensure the fire extinguishing effect, inert gas is introduced into the installation space 113. In one embodiment, an inert gas cylinder 136 is fixedly connected to the connecting block 109. An air outlet head 137 is fixedly arranged on the upper end wall of the installation space 113. The air outlet end of the inert gas cylinder 136 is communicated with the air outlet head 137 through a connecting structure. The air outlet head 137 is used to introduce inert gas into the installation space 113 for fire extinguishing.

[0053] To avoid the overflow of inert gas and reduce the usage amount as much as possible, in one embodiment, a connecting pipe 142 is connected to the air outlet of the inert gas cylinder 136 and the air outlet head 137. A rotating disk 139 rotatably arranged inside the connecting block 109, and a torsion spring is arranged between the rotating disk 139 and the connecting block 109. One end of each of the two connecting pipes 142 abuts against both sides of the rotating disk 139, and the two connecting pipes 142 are in sliding seal cooperation with the rotating disk 139. A through hole 140 for connecting the air outlet of the inert gas cylinder 136 and the air outlet head 137 is arranged on the rotating disk 139. A pulling rope block 141 is also fixedly connected to the rotating disk 139. A pulling rope 138 is connected to the pulling rope block 141, and one end of the pulling rope 138 is connected to the baffle 115. When the baffle 115 gradually moves to the position between the air suction port and the first channel 111, it will pull the pulling rope 138, thereby driving the rotating disk 139 to rotate, and then making the through hole 140 rotate to the position where the air outlet of the inert gas cylinder 136 and the air outlet head 137 are communicated, and discharging inert gas into the installation space 113.

[0054] When the inert gas enters the installation space 113, the baffle 115 will slide. After sucking the air in the installation space 113 into the annular airbag 108, when the baffle 115 resets, at this time, the inert gas continues to enter the installation space 113, and this process is repeated until the smoke sensor 125 detects that there is no smoke in the installation space 113. This avoids the problem that the inert gas cannot be introduced due to sealing. At this time, the first electromagnet 119 and the second electromagnet are re-energized, so that the baffle 115 continues to close the second channel 112, and the connecting pipe 110 and the suction hole 104 continue to dissipate heat.

[0055] Working or installation process:

[0056] 1. When dissipating heat, by starting the heat dissipation fan 105, the hot air in the installation space 113 is extracted through the suction hole 104, and at the same time, the outside cold air enters the installation space 113 through the heat dissipation slot 106. When a fire breaks out in the installation space 113, the smoke sensor 125 detects the combustion soot. At this time, the first electromagnet 119 and the second electromagnet are powered off, and under the action of the first spring 120, the baffle 115 moves between the first channel 111 and the suction hole 104.

[0057] 2. When the installation space 113 is not sealed, the extraction channel is in a negative pressure state under the action of the connecting pipe 110. At this time, it will drive the baffle 115 to move to connect the first channel 111 with the suction hole. The first impeller 117 can rotate. Under the action of the connecting pipe 110, the second impeller 143 rotates, driving the first impeller 117 to rotate, and the air mixed with combustion soot in the installation space 113 is extracted into the annular airbag 108 for convenient centralized treatment, causing the annular strong airbag to expand. One side of the annular airbag 108 abuts against one side of the power cabinet body 100 to close the heat dissipation slot 106. When the installation space 113 is sealed, the baffle 115 returns between the first channel 111 and the suction hole 104;

[0058] 3. Since the temperature of the combustion soot is relatively high, when it enters the annular airbag 108, under the action of the heat conduction block 134 and the thermal sensitive spring 135, the rubber protrusion 132 is pushed into the recess 133 to ensure the sealing effect.

[0059] 4. When the baffle 115 is located between the first channel 111 and the suction hole 104, the rotating disk 139 is rotated by pulling the pull rope 138, so that the inert gas cylinder 136 is communicated with the air outlet head 137, and inert gas is introduced into the installation space 113 to extinguish the fire. When the inert gas enters the installation space 113, the air pressure in the installation space 113 changes, which will drive the baffle 115 to move. At this time, the inert gas no longer enters, and at the same time, the first channel 111 continues to suck the air mixed with soot into the annular airbag 108. In this way, the inert gas is intermittently introduced repeatedly until the smoke sensor 125 no longer detects soot. At this time, the baffle 115 returns to its initial position and continues to start heat dissipation.
