Description

Technical Field

[0001] The present application relates to the technical field of environmental protection cabinets, and in particular to an environmental protection cabinet. Background Art

[0002] An environmental protection cabinet is an electrical device that connects distribution lines. It is an important switching device for ring network power supply and terminal power supply. Environmental protection cabinets are widely used in industrial places such as power plants and substations. Environmental protection cabinets usually have insulating gas inside to avoid leakage inside the cabinet and cause further power risks.

[0003] In the related technology, the environmental protection cabinet includes a cabinet body and a cabinet door. The cabinet door is rotatably connected to the cabinet body. The cabinet body is provided with a placement slot for placing power supply components. There are multiple placement slots. A heating plate is fixedly connected in the placement slot. The heating plate is used to heat the placement slot to reduce condensation in the placement slot.

[0004] Since there are usually multiple different electrical components in the placement slot, there are many wires electrically connected to the electrical components, and the wires are usually clamped on the slot wall of the placement slot, so that the heating plate is very likely to touch the wires during use, causing the heating plate to heat the wires and cause problems with the wires, affecting the use of the electrical components. Summary of the invention

[0005] In order to improve the problem that the heating plate is prone to interfere with the wires, the present application provides an environmental protection cabinet.

[0006] The present application provides an environmental protection cabinet, which adopts the following technical solution: An environmental protection cabinet comprises a cabinet body and a cabinet door, wherein the cabinet door is rotatably connected to the cabinet body, a plurality of placement grooves are provided on the cabinet body, support bars are provided in the placement grooves, a connecting plate is provided on the support bar, a heating plate is provided on the connecting plate, a connecting inclined surface is provided on the connecting plate, and the distance between the connecting inclined surface and the support bar gradually decreases in the vertical downward direction; when the heating plate is fixed on the connecting plate, the end of the heating plate away from the connecting plate is inclined in the direction away from the support bar.

[0007] By adopting the above technical solution, the heating plate is fixed on the connecting plate, and the heating plate is tilted along the direction of the connecting slope, so that the end groove of the heating plate away from the connecting plate is tilted in the direction away from the support bar, so that the heating plate can be facing the groove wall on the side away from the placement groove, so that the space between the heating plate and the wire can be increased, so that the wire clamp can be placed on the groove wall of the placement groove without abutting the heating plate, reducing the possibility of direct contact between the heating plate and the wire causing damage to the wire.

[0008] Optionally, a receiving groove communicating with the placement groove is formed in the cabinet body. A heat insulation curtain is rotatably connected in the receiving groove. A driving structure is arranged in the placement groove, and a moving plate for blocking the receiving groove is arranged on the driving structure; when a fire breaks out in the placement groove, the driving structure drives the moving plate not to block the receiving groove, and the completely lowered heat insulation curtain is located between two adjacent placement grooves.

[0009] By adopting the above technical solution, when a fire breaks out in the placement groove, the driving structure can drive the moving plate to move, so that the moving plate does not block the receiving groove, thereby enabling the heat insulation curtain to fall from the opening of the receiving groove, realizing that the heat insulation curtain can be located between two adjacent placement grooves, reducing the limitation of the fire breaking through the groove wall of the placement groove, reducing the influence of the fire on other positions of the cabinet body, and thus reducing the influence of the fire on the environmental protection cabinet.

[0010] Optionally, a jet structure is arranged in the placement groove. The jet structure contains a fire extinguishing agent, and the jet structure is located on the moving path of the moving plate; when the jet structure is squeezed, the jet structure sprays out the fire extinguishing agent.

[0011] By adopting the above technical solution, since the jet structure is located on the moving path of the moving plate, the moving plate can squeeze the jet structure, so that the jet structure can release the fire extinguishing agent, enabling the fire extinguishing agent to extinguish the fire in the placement groove, extinguishing the burning items, realizing automatic fire extinguishing in the cabinet body, and reducing the possibility of the fire spreading further due to no one extinguishing the fire.

[0012] Optionally, a rotating rod is rotatably connected in the receiving groove. The heat insulation curtain is arranged on the rotating rod. A rotating gear is arranged on the rotating rod, and a moving rack is meshed with the rotating gear. The jet structure is located on the moving path of the moving rack; when the heat insulation curtain completely falls, the moving rack squeezes the jet structure.

[0013] By adopting the above technical solution, when the heat insulation curtain falls, the heat insulation curtain can drive the rotating rod to rotate, and the rotating rod drives the rotating gear to rotate. Since the rotating gear is meshed with the moving rack and the jet structure is located on the moving path of the moving rack, the moving rack can squeeze the jet structure, enabling the jet structure to further release the fire extinguishing agent and reducing the possibility of residual fire extinguishing agent in the jet structure.

[0014] Optionally, a connecting pipe is arranged on the cabinet body. The connecting pipe connects multiple jet structures; when one of the jet structures is squeezed, the fire extinguishing agent in the other jet structures can move to the squeezed jet structure through the connecting pipe.

[0015] By adopting the above technical solution, when one of the jet structures is squeezed, the multiple jet structures are connected through the connecting pipes. Due to the air pressure, the fire extinguishing agent in other jet structures moves, causing the fire extinguishing agent to concentrate in the squeezed jet structure. Thus, the squeezed jet structure can have the fire extinguishing agent. When the moving rack squeezes the jet structure, the jet structure can still eject the fire extinguishing agent, further increasing the possibility of the fire extinguishing agent extinguishing the burning part. At the same time, due to the movement of the fire extinguishing agent in other jet structures, the fire extinguishing agent can extinguish the burning part, reducing the waste caused by long-term storage of the fire extinguishing agent.

[0016] Optionally, a fire extinguishing structure for ejecting fire extinguishing gas is provided on the cabinet body. A release pipe is provided on the fire extinguishing structure. A plurality of first openings are formed in the heat insulation curtain. The plurality of first openings are distributed along the vertical direction of the cabinet body. A flow channel communicating with the first openings is formed in the heat insulation curtain. When the heat insulation curtain completely drops, the release pipe communicates with the flow channel. When the driving structure is started and the temperature continues to rise, the fire extinguishing structure releases the fire extinguishing gas, and the fire extinguishing gas is ejected from the first openings.

[0017] By adopting the above technical solution, when the driving structure is started and the temperature continues to rise, the fire extinguishing structure is started, enabling the fire extinguishing structure to eject the fire extinguishing gas through the release pipe. Since the driving structure has been started, at this time, the heat insulation curtain completely drops, and the flow channel communicates with the release pipe, allowing the fire extinguishing gas to sequentially pass through the release pipe, the flow channel, and the first openings, enabling the fire extinguishing gas to be released. Coupled with the fact that the plurality of first openings are distributed along the vertical direction of the cabinet body, the fire extinguishing gas can quickly fill the interior of the placement groove, enabling the fire extinguishing gas to stably control the fire, reducing the possibility of the fire spreading further.

[0018] Optionally, a release nozzle is provided on the first opening. A through hole for the fire extinguishing gas to pass through is formed in the release nozzle. A guiding hole is formed in the hole wall of the through hole. The guiding hole extends along the circumferential direction of the through hole. The diameter of the guiding hole close to the flow channel is larger than the diameter of the guiding hole far from the flow channel.

[0019] By adopting the above technical solution, the fire extinguishing gas passes through the through hole. Since the guiding hole extends along the circumferential direction of the outlet, the fire extinguishing gas can rotate along the extending direction of the guiding hole, enabling the fire extinguishing gas to pass through the through hole rotatably, allowing the fire extinguishing gas to quickly reach the side of the placement groove far from the heat insulation curtain, enabling the fire extinguishing gas to quickly fill the placement groove. As the fire extinguishing gas moves in the guiding hole, since the diameter of the guiding hole close to the flow channel is larger than the diameter of the guiding hole far from the flow channel, the speed at which the fire extinguishing gas detaches from the guiding hole can be increased, thereby realizing the operation of quickly filling the placement groove with the fire extinguishing gas.

[0020] Optionally, a first magnet is provided on the heat insulation curtain, and a second magnet is provided on the wall of the receiving groove; when the first magnet adsorbs the second magnet, the flow channel communicates with the release pipe.

[0021] By adopting the above technical solution, the second magnet can limit the movement of the heat insulation curtain by adsorbing the first magnet. At this time, the flow channel communicates with the release pipe, so that the fire extinguishing gas can move from the release pipe to the flow channel, enabling the fire extinguishing gas to move stably.

[0022] In summary, the present application includes at least one of the following beneficial technical effects: 1. By fixing the heating plate on the connecting plate and tilting the heating plate along the direction of the connecting inclined surface, it is realized that the end of the heating plate away from the connecting plate is inclined away from the support bar, so that the heating plate can face the side wall away from the placement groove, increasing the space between the heating plate and the wire, so that the wire hoop is on the wall of the placement groove without contacting the heating plate, reducing the possibility of damage to the wire caused by direct contact between the heating plate and the wire.

[0023] 2. When one of the jet structures is squeezed, since multiple jet structures are connected through the connecting pipe, the other jet structures drive the fire extinguishing agent to move due to air pressure, concentrating the fire extinguishing agent in the squeezed jet structure, so that the squeezed jet structure can have the fire extinguishing agent. When the moving rack squeezes the jet structure, the jet structure can still spray the fire extinguishing agent, further increasing the possibility of extinguishing the fire part by the fire extinguishing agent; at the same time, through the movement of the fire extinguishing agent in the other jet structures, the fire extinguishing agent can extinguish the fire part, reducing the waste caused by long-term storage of the fire extinguishing agent.

Detailed implementation mode

[0026] The following further elaborates on this application Figures 1-7 in conjunction with the attached drawings.

[0027] Embodiment 1 This embodiment discloses an environmental protection cabinet. Refer to Figure 1 and Figure 2 , an environmental protection cabinet includes a cabinet body 1 and a cabinet door 11. The cabinet door 11 is rotatably connected to the cabinet body 1. A plurality of placement grooves 12 are formed in the cabinet body 1, and the placement grooves 12 are used for placing electrical components.

[0028] Refer to Figure 2 and Figure 3 , a support bar 13 is fixedly connected to the groove wall of the placement groove 12, and the support bar 13 extends in the vertical direction. A connecting plate 131 is fixedly connected to the support bar 13, and the connecting plate 131 extends in the horizontal direction. There is a certain space between the connecting plate 131 and the groove wall of the placement groove 12. A heating plate 132 is provided on the surface of the connecting plate 131, and a fixing bolt 133 is provided on the heating plate 132. The fixing bolt 133 passes through the heating plate 132 and is fixed to the connecting plate 131. A connecting inclined surface 135 is formed on the surface of the connecting plate 131 away from the support bar 13, and the distance between the connecting inclined surface 135 and the support bar 13 gradually decreases in the vertically downward direction.

[0029] Refer to Figure 2 and Figure 3 , when the heating plate 132 is fixed to the connecting plate 131, the end of the heating plate 132 away from the connecting plate 131 can tilt away from the support bar 13, increasing the distance between the heating plate 132 and the groove wall of the placement groove 12 to reduce the possibility of contact between the wire hoop on the groove wall of the placement groove 12 and the heating plate 132.

[0030] Refer to Figure 2 and Figure 3, a humidity sensor 134 is fixedly connected inside the placement groove 12. The humidity sensor 134 can detect the humidity inside the placement groove 12, and the humidity sensor 134 is electrically connected to the heating plate 132. When the humidity sensor 134 detects excessive humidity, the humidity sensor 134 drives the heating plate 132 to start, so that the heating plate 132 heats the inside of the placement groove 12 to reduce the condensation phenomenon on the wall of the placement groove 12.

[0031] The implementation principle of Embodiment 1 is that one end of the heating plate 132 away from the connecting plate 131 can be inclined away from the support bar 13, increasing the distance between the heating plate 132 and the wire.

[0032] Embodiment 2 Refer to Figure 4 and Figure 5 , the difference between this embodiment and Embodiment 1 is that a receiving groove 2 communicating with the placement groove 12 is opened on the cabinet body 1. A rotating rod 21 is rotatably connected inside the receiving groove 2, and the rotating rod 21 extends along the width direction of the cabinet body 1. A heat insulation curtain 22 is fixedly connected to the outer surface of the rotating rod 21. The heat insulation curtain 22 is made of a flexible material, and the heat insulation curtain 22 can perform heat insulation treatment.

[0033] Refer to Figure 5 , a moving block 221 is fixedly connected to the end face of the heat insulation curtain 22 away from the rotating rod 21. A moving groove 222 for inserting the moving block 221 is opened on the wall of the placement groove 12, and the moving groove 222 extends into the receiving groove 2, and the moving groove 222 extends in the vertical direction.

[0034] Refer to Figure 5 , a driving structure 23 is provided inside the placement groove 12. The driving structure 23 includes a driving cylinder and a temperature sensor. The temperature sensor is fixedly connected to the placement groove 12, and the temperature sensor is electrically connected to the driving cylinder. The driving cylinder is fixedly connected to the wall of the placement groove 12, and a moving plate 231 is fixedly connected to the driving shaft of the driving cylinder. The moving plate 231 is used to block the opening of the receiving groove 2. When the driving cylinder drives the moving plate 231 not to block the receiving groove 2, the moving block 221 can move in the moving groove 222, so that the heat insulation curtain 22 can fall smoothly, and the heat insulation curtain 22 can be located between two adjacent placement grooves 12, realizing that the heat insulation curtain 22 restricts the fire area from spreading to other areas.

[0035] Refer to Figure 5, a jetting structure 3 is provided inside the placement groove 12. The jetting structure 3 is made of an airbag, and the interior of the jetting structure 3 contains a fire extinguishing agent, which is perfluoromethylcyclohexanone. The jetting structure 3 is located on the moving path of the moving plate 231, that is, when the moving plate 231 does not block the receiving groove 2, the moving plate 231 can squeeze the jetting structure 3. When the jetting structure 3 is squeezed, the jetting structure 3 can eject the fire extinguishing agent, enabling the fire extinguishing agent to spread from the opening of the receiving groove 2 into the placement groove 12, so as to extinguish the fire at the ignition location.

[0036] Refer to Figure 5 , a connection hole 31 is formed on the cabinet body 1, and the connection hole 31 communicates with a plurality of placement grooves 12. A connection pipe 32 is fixedly connected inside the connection hole 31, and the connection pipe 32 is connected to a plurality of jetting structures 3. When one of the jetting structures 3 is squeezed, the fire extinguishing agents in the other jetting structures 3 are not consumed, so that the pressure of the fire extinguishing agents in the other jetting structures 3 is relatively high, and the fire extinguishing agents in the other jetting structures 3 can move from the connection pipe 32 into this jetting structure 3, enabling the fire extinguishing agent in this jetting structure 3 to be replenished, so as to facilitate the jetting structure 3 to continue ejecting the fire extinguishing agent.

[0037] Refer to Figure 5 and Figure 6 , a rotating gear 24 is fixedly connected to the outer surface of the rotating rod 21, and a moving rack 241 is slidably connected to the groove wall of the receiving groove 2. The moving rack 241 is meshed and connected to the rotating gear 24. An extrusion plate 242 is fixedly connected to the surface of the moving rack 241, and the jetting structure 3 is located on the moving path of the extrusion plate 242. When the heat insulation curtain 22 completely drops, the rotating rod 21 drives the moving rack 241 to move through the rotating gear 24, enabling the moving rack 241 to squeeze the jetting structure 3, so that the fire extinguishing agent in the jetting structure 3 can be ejected again.

[0038] Refer to Figure 5 and Figure 6 , when a fire breaks out in the placement groove 12, the driving cylinder first drives the moving plate 231 to abut against the jetting structure 3. At this time, the heat insulation curtain 22 drops. During the process of waiting for the heat insulation curtain 22 to completely drop, the fire extinguishing agents in the other jetting structures 3 can move into this jetting structure 3, and the heat insulation curtain 22 drives the moving rack 241 to squeeze this jetting structure 3 through the rotating gear 24, enabling the jetting structure 3 to eject the fire extinguishing agent again.

[0039] Refer to Figure 5 and Figure 6 , a fire extinguishing structure 4 is provided on the cabinet body 1. The fire extinguishing structure 4 includes a fire extinguishing component, and the fire extinguishing component is electrically connected to a temperature sensor. The fire extinguishing component is fixedly connected to the cabinet body 1, and a plurality of release pipes 41 are fixedly connected to the cabinet body 1. The release pipes 41 communicate with the fire extinguishing component, that is, the fire extinguishing component can release fire extinguishing gas in the release pipes 41, and the fire extinguishing gas is carbon dioxide gas.

[0040] Reference Figure 6 Figure 6 When the temperature sensor first detects that the temperature is too high, the temperature sensor activates the driving cylinder to achieve primary fire extinguishing. If the fire is not extinguished and the temperature sensor detects that the temperature continues to rise, the temperature sensor activates the fire extinguishing component to release the fire extinguishing gas from the fire extinguishing component to achieve secondary fire extinguishing.

[0041] Reference Figure 6 and Figure 7 Figure 7 As shown in FIGS. and, a flow channel 25 is formed on the surface of the heat insulation curtain 22. The flow channel 25 extends along the length direction of the heat insulation curtain 22. A plurality of first openings 251 are formed on the surface of the heat insulation curtain 22. The plurality of first openings 251 communicate with the flow channel 25. The plurality of first openings 251 are arranged in an array along the length direction of the heat insulation curtain 22. When the heat insulation curtain 22 completely drops, the flow channel 25 communicates with the release pipe 41, so that the fire extinguishing gas moves from the release pipe 41 to the flow channel 25.

[0042] Reference Figure 5 、 Figure 6 and Figure 7 Figure 7 As shown in FIGS.,, and, a groove is formed on the surface of the heat insulation curtain 22. A first magnet 26 is fixedly connected in the groove. A second magnet 261 is fixedly connected to the wall of the receiving groove 2. The first magnet 26 adsorbs the second magnet 261. When the first magnet 26 adsorbs the second magnet 261, the heat insulation curtain 22 is fixed to the cabinet body 1. At this time, the heat insulation curtain 22 completely drops, and the flow channel 25 communicates with the release pipe 41.

[0043] Reference Figure 7 Figure 7 A release nozzle 252 is fixedly connected in the first opening 251. A through hole 253 for the fire extinguishing gas to pass through is formed in the release nozzle 252. The through hole 253 communicates with the first opening 251. A guiding hole 254 is formed on the wall of the through hole 253. The guiding hole 254 extends along the circumferential direction of the through hole 253. The diameter of the guiding hole 254 close to the flow channel 25 is larger than the diameter of the guiding hole 254 far from the flow channel 25, so that the fire extinguishing gas is released from the release nozzle 252 along the extending direction of the guiding hole 254, and the fire extinguishing gas rotates when being released from the release nozzle 252 to increase the spraying distance of the fire extinguishing gas.

[0044]

[0044] The implementation principle of Embodiment 2 is as follows: When a fire breaks out in the placement groove 12, the temperature sensor detects that the temperature is too high. The temperature sensor activates the driving cylinder to drive the moving plate 231 to move, so that the moving plate 231 does not block the receiving groove 2, and the moving plate 231 abuts against the jet structure 3, so that the jet structure 3 sprays out the fire extinguishing agent. At this time, the heat insulation curtain 22 drops; If the fire in the placement groove 12 is still not extinguished and the temperature sensor detects that the temperature is still rising continuously, the temperature sensor activates the fire extinguishing component to release the fire extinguishing gas, so that the fire extinguishing gas passes through the release pipeline 41, the flow channel 25, the first opening 251 and the release nozzle 252 in sequence, and the fire extinguishing gas spreads into the placement groove 12 to reduce the possibility of further expansion of the fire.
