Description

Technical Field

[0001] The present application relates to the technical field of power supply cabinets, and in particular to a cabinet structure of an intelligent AC power supply cabinet. Background Art

[0002] Intelligent power cabinet is a power management device that integrates intelligent technology and functions. Intelligent power cabinets are usually efficient, safe and reliable, and are widely used in various places that require power management and distribution. Through the built-in intelligent system, they realize the monitoring, control, protection and optimization of power input, thereby improving the efficiency and safety of power use. Existing intelligent power cabinets usually have multiple power distribution components and a variety of power distribution equipment installed inside, which will generate a lot of heat during operation. In order to ensure the heat dissipation requirements, heat dissipation slots and heat dissipation fans are usually used to dissipate the heat inside the power cabinet. However, when the temperature in the power cabinet is too high and a fire occurs, although the fire extinguishing equipment in the cabinet will extinguish the fire, the heat dissipation slot will introduce fresh air into the power cabinet, causing the fire to increase, and the burning smoke will also overflow to the outside, causing safety hazards. Therefore, it is necessary to close the heat dissipation port to prevent fresh air from entering and prevent the burning smoke from overflowing, but this will cause a high-pressure state to form in the cabinet, posing a safety hazard.

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

The content of this application is not intended to identify the key features or essential features of the technical solution claimed for protection, nor is it intended to limit the scope of the technical solution claimed for protection.

[0006] By setting up multiple installation spaces, when a fire occurs in one installation space, it will not affect the operation of equipment in other installation spaces. By setting up the heat dissipation grooves and air intake holes, when heat dissipation is required, the hot air in the installation space is extracted through the air intake holes and cold air enters the installation space from the heat dissipation grooves for heat dissipation. By setting up the installation plate and the annular airbag, when a fire occurs in the installation space and it needs to be sealed, the annular airbag is expanded and attached to one side of the power cabinet, and the heat dissipation groove is closed in cooperation with the installation plate to achieve the sealing of the installation space. By setting up the baffle, when a fire occurs in the installation space, the baffle will separate the air intake air from the connecting pipe to prevent the combustion smoke in the installation space from being discharged along with the operation of the cooling fan. At the same time, the air containing smoke is extracted into the annular airbag through the first impeller and the second impeller to avoid hidden dangers caused by the high pressure state formed in the installation space due to combustion. Through the setting of the 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 insulation cavity is drawn out and flows through the second channel, thereby cooling the partition to avoid the temperature of the adjacent installation space increasing due to the excessively high fire temperature in the installation space.

[0007] Furthermore, a mounting frame located between the connection position of the connecting pipe and the second channel is fixedly connected in the air intake channel, a first electromagnet is fixedly connected on the mounting frame, the first electromagnet is used to attract the baffle, a first spring is arranged between the baffle and the mounting frame, a limiting groove located between the connection position of the connecting pipe and the first channel is opened on the side wall of the air intake channel, a limiting block for limiting the baffle 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, and a second spring is also arranged between the limiting block and the inner wall of the limiting groove.

[0008] By setting the first electromagnet and the second electromagnet, when a fire occurs in the installation space, the first electromagnet and the second electromagnet are both powered off, and the baffle moves to between the connection position of the connecting pipe and the first channel under the action of the first spring. At this time, the smoke-containing gas sucked into the suction channel from the suction hole is sucked into the first channel and discharged into the annular airbag through the exhaust pipe to avoid direct discharge of the smoke-containing gas. When the second electromagnet is powered off, the limit block can limit the baffle, thereby ensuring that the connection position of the connecting pipe is separated from the suction hole. At the same time, the limit block has an inclined surface.

[0009] Furthermore, the fire extinguishing assembly includes: an inert gas bottle fixed on the connecting block, a gas outlet head fixedly provided on the upper end wall of the installation space, the gas outlet end of the inert gas bottle is connected to the gas outlet head through a connecting structure, and the gas outlet head is used to introduce inert gas into the installation space for fire extinguishing.

[0010] By providing the gas outlet head and the inert gas bottle, when a fire occurs, the inert gas can be filled into the installation space through the inert gas bottle to extinguish the fire.

[0011] Furthermore, the connecting structure includes: a connecting pipe connected to the gas outlet of the inert gas bottle and the gas outlet head, a rotating disk rotatably arranged in the connecting block, one end of the two connecting pipes respectively abutting against two sides of the rotating disk, a through hole for connecting the gas outlet of the inert gas bottle and the gas outlet head is arranged on the rotating disk, and a pull rope block is also fixedly connected to the rotating disk, a pull rope is connected to the pull rope block, and one end of the pull rope is connected to the baffle.

[0012] Through the provided connecting pipe and rotating disk, when the smoke-containing waste in the installation space enters the annular airbag, the baffle gradually moves to the position between the air intake port and the first channel, thereby pulling the pull rope, thereby driving the rotating disk to rotate, and then the through hole rotates to the position connected to the air outlet of the inert gas bottle and the air outlet head, and the inert gas is discharged into the installation space. When the inert gas enters the installation space, the air pressure in the installation space changes, causing the baffle to move again between the connection position of the connecting pipe and the first channel. At this time, the inert gas stops entering until the baffle continues to be located between the air intake port and the first channel, thereby realizing repeated introduction of inert gas into the installation space to avoid excessive use of inert gas.

[0013] Furthermore, 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 in is opened on the side wall of the power cabinet close to the annular airbag, two rubber protrusions are movably arranged on the sealing block, and a depression for the rubber protrusion to be embedded in is opened on the side wall of the sealing groove.

[0014] By providing the sealing block and the rubber protrusion, when the sealing block is embedded in the sealing groove, the limiting protrusion is also embedded in the recess, thereby ensuring the sealing effect.

[0015] Furthermore, a heat conductive block having one end extending into the annular airbag is fixedly connected inside the sealing block, a thermistor spring in contact with the heat conductive block is fixedly connected inside the sealing block, and one end of the thermistor spring abuts against the rubber protrusion for pushing the rubber protrusion into the recess.

[0016] Through the heat-conducting block, the air containing smoke and dust has a high temperature under the action of combustion, which makes the thermal spring extend, and then pushes the rubber protrusion into the depression to ensure sealing.

[0017] Furthermore, the transmission structure includes a transmission shaft rotatably arranged in the connecting 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 transmission-connected between the first impeller and the transmission shaft.

[0018] The transmission structure is arranged so that the first impeller and the second impeller rotate synchronously.

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

[0020] The beneficial effects of this application are: 1. Through the provided heat dissipation slots and air intake holes, when heat dissipation is required, the hot air in the installation space is extracted through the air intake holes, and the cold air enters the installation space from the heat dissipation slots for heat dissipation. Through the provided mounting plate and annular airbag, when a fire occurs in the installation space and it needs to be sealed, the annular airbag expands and fits to one side of the power cabinet, and cooperates with the mounting plate to close the heat dissipation slot, thereby achieving sealing of the installation space.

[0021] 2. Through the baffle, when a fire occurs in the installation space, the baffle will suck air into the connecting pipe to prevent the combustion smoke in the installation space from being discharged with the cooling fan. At the same time, through the first impeller and the second impeller, the air containing smoke is drawn into the annular air bag to avoid hidden dangers caused by high pressure in the installation space due to combustion.

[0022] 3. Through the setting of the insulation cavity, when there is a positive pressure in the installation space, the first impeller can rotate synchronously with the second impeller, so that the air in the insulation cavity is drawn out and flows through the second channel, and the partition is cooled to avoid the temperature of the adjacent installation space rising due to the excessively high fire temperature of the installation space.

[0031] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0032] Reference Figure 1-11 A smart AC power cabinet structure includes: a power cabinet 100, a partition plate 101, a sealing door 102, a heat dissipation frame 103, an air intake hole 104, a heat dissipation fan 105, a heat dissipation slot 106, a mounting plate 107, a shaped air bag, a connecting block 109, a connecting pipe 110, a first channel 111, and a second channel 112. Two partition plates 101 are fixed in the power cabinet 100, and the two partition plates 101 divide the inner cavity of the power cabinet 100 into three installation spaces 113 that are not connected to each other. The installation space 113 is sealed by the sealing door 102, so that the installation space 113 is cooled through the heat dissipation slot 106. In one embodiment, in order to ensure the heat dissipation effect, the heat dissipation frame 103 is fixedly arranged on one side of the power cabinet 100, and the heat dissipation hole 104 that is connected to the installation space 113 is arranged on the heat dissipation frame 103, and the heat dissipation slot 106 is opened on one side wall of the installation space 113, and the heat dissipation slot 106 is arranged opposite to the air intake hole 104. When the air intake hole 104 inhales air, cold air enters the installation space 113 through the heat dissipation slot 106. A heat dissipation fan 105 is fixedly connected to the heat dissipation frame 103, and the air inlet end of the heat dissipation fan 105 is connected to the air intake hole 104 through a pipe. In one embodiment, when a fire occurs in one of the installation spaces 113, the installation space 113 needs to be closed to prevent oxygen from continuously entering. A mounting plate 107 located on one side of the heat dissipation slot 106 is fixedly connected to the power cabinet 100, and an annular airbag 108 is fixedly connected to the mounting plate 107. The annular airbag 108 is arranged around the outer periphery of the heat dissipation slot 106. When heat is dissipated, the annular airbag 108 does not expand, and air enters the heat dissipation slot 106 from the gap between the mounting plate 107 and the power cabinet 100. When it needs to be closed, the annular airbag 108 expands, and one side is attached to the side of the power cabinet 100, and the heat dissipation slot 106 is closed with the mounting plate 107, thereby sealing.

[0033] In order to detect whether the sealing is achieved, in one embodiment, a connection block 109 corresponding to the installation space 113 is fixedly provided in the heat dissipation frame 103, and an extraction channel connected to the air suction hole 104 is provided in the connection block 109, wherein the air inlet end of the heat dissipation fan 105 is connected to the extraction channel through the connection pipe 110, and when the heat dissipation fan is started, a negative pressure is formed in the extraction channel, thereby extracting the gas in the installation space 113. A baffle 115 is slidably connected in the extraction channel to separate the air suction hole 104 from the connection pipe 110. At the same time, a first channel 111 and a second channel 112 are provided in the connection block 109, and the connection between the first channel 111 and the extraction channel is located between the air suction hole and the connection pipe 110, and a one-way valve 116 for gas to flow from the air suction cavity to the first channel 111 is provided at the connection of the first channel 111, and the connection between the second channel 112 and the extraction channel is located on one side of the connection pipe 110. The first impeller 117 and the second impeller 143, which are respectively located at the positions of the first channel 111 and the second channel 112, are rotatably connected in the connecting block 109. The first impeller 117 and the second impeller 143 are connected by a transmission structure. The first impeller 117 is used to rotate so that the airflow flows in the first channel 111, and the second impeller 143 is used to rotate with the airflow flowing in the second channel 112. When the baffle 115 is located between the second channel 112 and the connecting pipe 110, the air in the installation space 113 enters the extraction channel through the air intake hole 104 and is blown out by the cooling fan 105 through the connecting pipe 110, and heat is dissipated at this time. When the baffle 115 is located between the first channel 111 and the air intake hole 104, the first impeller 117 cannot rotate under the action of the one-way valve 116, and the second impeller 143 does not rotate at this time. If the installation space 113 is not completely sealed, the baffle 115 will slide under the action of air pressure until the first channel 111 is connected to the air intake hole 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 and then drives the first impeller 117 to rotate, so that the gas in the installation space 113 is discharged through the first channel 111. In order 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 arranged in the partition. The second channel 112 is connected to the insulation cavity 144 through a pipeline, 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 in the insulation cavity 144 to circulate, avoiding the temperature of an adjacent installation space 113 from rising.

[0034] When the installation space 113 is sealed, the air in the installation space 113 is drawn into the annular airbag 108, so that the annular airbag 108 expands and seals. The annular airbag 108 is connected to an external airbag through a constant pressure valve. When the air pressure of the annular airbag 108 reaches the threshold of the constant pressure valve, the airbag is exhausted to the outside. When the installation space 113 is closed, the baffle 115 returns to between the air suction hole 104 and the first channel 111, and the installation space 113 is closed.

[0035] 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.

[0036] A mounting frame 118 located between the connection position of the connecting pipe 110 and the second channel 112 is fixedly connected in the air intake channel, and a first electromagnet 119 is fixedly connected to the mounting frame 118. The first electromagnet 119 is used to attract the baffle 115. A first spring 120 is arranged between the baffle 115 and the mounting frame 118. The two ends of the first spring 120 are respectively fixed to the baffle 115 and the mounting frame 118. A limiting groove 121 located between the connection position of the connecting pipe 110 and the first channel 111 is provided on the side wall of the air intake channel. A limiting block 122 for limiting the baffle 115 is arranged in the limiting groove 121. 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 also arranged 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. At the same time, a smoke sensor 125 is provided in the installation space 113, and a controller is provided in the power cabinet 100. The controller is used to receive the signal of the smoke sensor 125 and control the first electromagnet 119 and the second electromagnet. When a fire occurs in one of the installation spaces 113, the smoke sensor 125 detects the signal and transmits the signal to the control center. The control center controls the first electromagnet 119 and the second electromagnet to be powered off, so that the baffle 115 slides from between the connecting pipe 110 and the second channel 112 to between the first channel 111 and the connecting pipe 110 under the action of the spring. At this time, the first channel 111 can inhale the air of the suction hole 104. When the first spring 120 is not stressed, the baffle 115 is located between the first channel 111 and the connecting rod.

[0037] 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 transmission-connected between the first impeller 117 and the transmission shaft 126 .

[0038] In order 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 provided on one side wall of the power cabinet 100 close to the annular airbag 108. Two rubber protrusions 132 are movably provided on the sealing block 130. The connection between the sealing block 130 and the rubber protrusion 132 is set to be made of rubber material. A recess 133 for the rubber protrusion 132 to be embedded is provided 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 thermistor spring 135 in contact with the heat conducting block 134 is fixedly connected inside the sealing block 130. One end of the thermistor spring 135 abuts against the rubber protrusion 132, which is used to push the rubber protrusion 132 into the recess 133. Since the air containing smoke and dust entering the annular airbag 108 is at a high temperature, the thermal spring 135 expands, thereby pushing the rubber protrusion 132 to the depression 133 to ensure the sealing effect.

[0039] In order to ensure the fire extinguishing effect, inert gas is introduced into the installation space 113. In one embodiment, an inert gas bottle 136 is fixedly connected to the connecting block 109, and a gas outlet head 137 is fixedly provided on the upper end wall of the installation space 113. The gas outlet end of the inert gas bottle 136 is connected to the gas outlet head 137 through a connecting structure. The gas outlet head 137 is used to introduce inert gas into the installation space 113 for fire extinguishing.

[0040] In order to prevent the inert gas from overflowing and reduce the usage as much as possible, in one embodiment, the connecting pipe 142 on the gas outlet of the inert gas bottle 136 and the gas outlet head 137 rotates the rotating disk 139 disposed in the connecting block 109, and a torsion spring is disposed between the rotating disk 139 and the connecting block 109. One end of the two connecting pipes 142 abuts against the two sides of the rotating disk 139 respectively, and the two connecting pipes 142 and the rotating disk 139 are slidably sealed. The rotating disk 139 is provided with a through hole 140 for connecting the gas outlet of the inert gas bottle 136 and the gas outlet head 137. The rotating disk 139 is also fixedly connected with a drawstring block 141, and the drawstring block 141 is connected with a drawstring 138, and one end of the drawstring 138 is connected to the baffle 115. When the baffle 115 gradually moves to the position between the air intake port and the first channel 111, it pulls the pull rope 138, thereby driving the rotating disk 139 to rotate, and then the through hole 140 rotates to the position connected to the air outlet of the inert gas bottle 136 and the air outlet head 137, and the inert gas is discharged into the installation space 113.

[0041] When the inert gas enters the installation space 113, the baffle 115 will slide, and the air in the installation space 113 will be sucked into the annular airbag 108. When the baffle 115 is reset, the inert gas will continue to enter the installation space 113, and this will be repeated until the smoke sensor 125 detects that there is no smoke in the installation space 113. The problem of the inert gas being unable to enter due to sealing is avoided. 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 air intake hole 104 continue to dissipate heat.

[0042] Working or installation process: 1. When heat dissipation is performed, the heat dissipation fan 105 is started to extract the hot air in the installation space 113 through the air intake hole 104, and the cold air from the outside enters the installation space 113 through the heat dissipation slot 106. When a fire occurs in the installation space 113, the smoke sensor 125 detects the burning smoke. At this time, the first electromagnet 119 and the second electromagnet are controlled to be de-energized, and the baffle 115 moves to between the first channel 111 and the air intake hole 104 under the action of the first spring 120.

[0043] 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, the baffle 115 is driven to move to the first channel 111 to communicate with the suction air, and 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 smoke in the installation space 113 is extracted into the annular airbag 108, which is convenient for centralized processing, so that the annular airbag expands, and one side of the annular airbag 108 abuts against one side of the power cabinet 100 to close the heat dissipation slot 106. When the installation space 113 is closed, the baffle 115 returns to between the first channel 111 and the suction hole 104; 3. Since the temperature of the combustion smoke is relatively high, when it enters the annular airbag 108, the rubber protrusion 132 is pushed into the depression 133 under the action of the heat conductive block 134 and the thermal spring 135 to ensure the sealing effect.

[0044] 4. When the baffle 115 is located between the first channel 111 and the air inlet 104, the rotating disk 139 is rotated by pulling the pull rope 138, so that the inert gas bottle 136 is connected to the gas outlet 137, and the 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 the first channel 111 continues to inhale the air mixed with smoke into the annular airbag 108. The inert gas is repeatedly introduced intermittently until the smoke sensor 125 no longer detects smoke. At this time, the baffle 115 returns to the initial position and continues to dissipate heat.
