Description

Technical Field

[0001] The present invention relates to the technical field of explosion-proof cabinets, in particular to a data exchange device with explosion-proof function. Background Art

[0002] With the continuous development of my country's industry and the increasing scale of production, explosion-proof cabinets are increasingly being used in hazardous industries such as petroleum, chemical, metallurgy, and oil fields in Zone 1 (locations where an explosive gas atmosphere may occur during normal operation) and Zone 2 (locations where an explosive gas atmosphere is unlikely to occur during normal operation, or if it does occur, it will only occur occasionally and for short periods of time), where explosive gases or vapors are present. Explosion-proof cabinets are equipment for mounting control system hardware components and electrical components (controllers, communication modules, I / O cards, power supplies, cables, etc.). Heat-generating components or high-power heat-generating parts are densely installed inside the cabinets, generating significant heat over long-term operation.

[0003] Chinese patent application number CN202111650322.7 discloses an explosion-proof cabinet and explosion-proof machine, comprising a cabinet body with a liquid-cooled radiator mounted on the cabinet door; the liquid-cooled radiator includes a pipe with a liquid inlet and a liquid outlet at each end of the pipe, the inlet being connected to a liquid pump and the outlet being connected to a drain pipe. The cabinet has a hollow interior for housing an explosion-proof unit. The unit generates heat during operation, which is dissipated through the liquid-cooled radiator, dissipating the heat.

[0004] Chinese patent application number CN202410275490.X discloses an explosion-proof power distribution cabinet comprising a supporting main body, several connection components disposed within the main body, and a main control panel disposed on one surface of the main body. The invention utilizes a limit block and a stop block to limit the position of the cables, preventing them from becoming tangled while also facilitating the individual cable extraction. The limit teeth engage the outer side of the limit gear, thereby limiting the position of the rocker plate.

[0005] After the explosion-proof cabinet and the cover are fixed with fixing bolts and nuts, the internal space of the explosion-proof cabinet is closed. The data switch generates heat during use. As the heat accumulates, the probability of failure of the data switch increases. Due to the limitations of the equipment's operating environment, the installation of a cooling fan on a conventional explosion-proof cabinet will cause the equipment's explosion-proof performance to be lost. Once the explosion occurs due to the high temperature inside the explosion-proof cabinet, the data in the data switch is also easily damaged, and continuous power supply will also aggravate the combustion and explosion. Summary of the Invention

[0006] In order to solve the above technical problems, the present invention provides a data exchange device with explosion-proof function.

[0007] The present invention provides a data exchange device with explosion-proof function, comprising an explosion-proof cabinet, a data exchanger disposed inside the explosion-proof cabinet, an auxiliary regulating device disposed at the lower end of the explosion-proof cabinet, a circulating pump disposed outside the explosion-proof cabinet, the circulating pump being connected to the auxiliary regulating device, and a temperature sensor disposed inside the explosion-proof cabinet; The auxiliary adjustment device includes an adjustment plate, a through hole is provided on the adjustment plate, a shell is provided on the outside of the adjustment plate, an opening matching the through hole is provided on the shell, and a connector is also provided on the side end of the adjustment plate.

[0008] The data switch generates heat during operation. Under the action of the heated and easily expanded liquid in the drive cylinder, the adjustment plate is pushed, thereby increasing the overlap between the opening and the through hole, and increasing the cooling water flow in the circulation pipe to enhance the cooling effect.

[0009] Preferably, the lower end of the explosion-proof cabinet is provided with a hole position matching the outer shell, the outer shell and the explosion-proof cabinet are welded and sealed, the upper and lower ends of the opening are provided with connectors, the two upper connectors are provided with circulation pipes, and the two lower connectors are connected to the inlet and outlet liquid pipes of the circulation pump, and the circulation pipe is S-shaped.

[0010] Preferably, the shell is provided with wiring holes, and the wiring holes at the upper and lower ends are plugged with wiring heads. An adapter is provided at the lower end of the data switch inside the explosion-proof cabinet, and the wiring head at the upper end is connected to the data switch with the assistance of the adapter. The wiring adapter is located between the two wiring heads at the upper and lower ends, and the two wiring heads at the upper and lower ends are connected through the wiring adapter.

[0011] Preferably, the shell is divided into two parts, an upper part and an lower part, and there is a cavity between the upper and lower parts of the shell. The adjustment plate slides horizontally in the cavity. A driving cylinder is provided in the cavity. A liquid that is easily expanded when heated is provided in the driving cylinder. The output rod of the driving cylinder is connected to the side end of the adjustment plate. The cavity is also provided with an electric push rod at the position of the driving cylinder, and the output end of the electric push rod is located at the side end of the adjustment plate.

[0012] As the temperature continues to rise, passive cooling can no longer meet the requirements due to the resistance of the damping cylinder, and the equipment's active cooling adjustment begins to intervene. That is, the electric push rod is controlled to start according to the detection of the temperature sensor, and the overlap between the opening and the through hole is continued to increase to enhance the cooling effect. At the same time, the adjustment plate will push the connector to move, causing the wiring protrusion and the wiring slot to be misaligned, thereby disconnecting the wiring heads at the upper and lower ends, thereby disconnecting the circuit of the data switch and protecting the data switch.

[0013] When the temperature sensor detects the presence of an open flame in the explosion-proof cabinet, the device will control the output end of the electric push rod to extend to the limit distance, and the opening and the through hole will completely overlap. Therefore, the cooling water flow in the circulation pipe reaches the maximum, that is, the pressure condition for the pressure valve to open is reached, and the cooling water in the circulation pipe is sprayed outward through the spray pipe. By spraying cooling water outward, the combustion inside the explosion-proof cabinet is suppressed.

[0014] Preferably, a damping cylinder is provided in the cavity at the side end of the connector, the output end of the damping cylinder is connected to the connector, and the damping cylinder is located on a side of the connector away from the adjustment plate.

[0018] Compared with the prior art, the present invention has the following beneficial effects: 1. By setting up components such as the adjustment plate, connector and drive cylinder, the data switch generates heat during operation. Under the action of the heated and easily expanded liquid in the drive cylinder, the adjustment plate is pushed, thereby increasing the overlap between the opening and the through hole, and increasing the cooling water flow in the circulation pipe to enhance the cooling effect.

[0019] 2. By setting up components such as the adjustment plate, connector, drive cylinder and electric push rod, as the temperature continues to rise, due to the resistance of the damping cylinder, passive cooling can no longer meet the requirements, and the active temperature reduction adjustment of the equipment begins to intervene, that is, through the detection of the temperature sensor, the corresponding control electric push rod is started to continue to increase the overlap between the opening and the through hole to enhance the cooling effect. At the same time, the adjustment plate will push the connector to move, causing the wiring protrusion and the wiring slot to be misaligned, thereby disconnecting the wiring heads at the upper and lower ends, thereby disconnecting the circuit of the data switch and protecting the data switch.

[0020] 3. By setting up components such as the adjustment plate, connector, drive cylinder and electric push rod, when the presence of an open flame in the explosion-proof cabinet is detected with the assistance of a temperature sensor, the equipment will control the output end of the electric push rod to extend to the limit distance, and the opening and the through hole will completely coincide. Therefore, the cooling water flow in the circulation pipe reaches the maximum, that is, the pressure condition for the pressure valve to open is reached, and the cooling water in the circulation pipe is sprayed outward through the spray pipe. By spraying cooling water outward, the combustion inside the explosion-proof cabinet is suppressed. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] To facilitate understanding of the present invention, the present invention will be described more fully below with reference to the accompanying drawings. The present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0024] like Figures 1 to 3As shown, the present invention discloses a data exchange device with explosion-proof function, including an explosion-proof cabinet 1, a data switch 2 is provided in the explosion-proof cabinet 1, an adapter 4 is provided at the lower end of the data switch 2 inside the explosion-proof cabinet 1, a fixing frame 5 is provided on the explosion-proof cabinet 1, a cover plate 6 is further provided at the side end of the explosion-proof cabinet 1, fixing bolts and nuts 7 are provided between the explosion-proof cabinet 1 and the cover plate 6, a handle 8 is provided on the cover plate 6, and a hinge 9 is further provided between the cover plate 6 and the explosion-proof cabinet 1. During the use of the device, after the data switch 2 and the adapter 4 are installed, the handle 8 and the hinge are used to connect the data switch 2 and the adapter 4. 9, the cover plate 6 is covered on the explosion-proof cabinet 1, and then the cover plate 6 is connected and fixed to the explosion-proof cabinet 1 with the help of the fixing bolts and nuts 7. The explosion-proof cabinet 1 is fixed to the wall mounting position with the help of the fixing bracket 5. During the use of the equipment, if the internal data switch 2 fails due to excessive voltage or other problems, thereby causing circuit sparks or burning, the explosion-proof cabinet 1 and the cover plate 6 can isolate the sparks and burning phenomena to prevent the internal sparks or burning phenomena from spreading outward and causing larger accidents, thereby improving the safety of the equipment.

[0025] A glass window 10 and a control panel 11 are provided on the cover plate 6. A display screen 12 is also provided in the explosion-proof cabinet 1. The display screen 12 matches the position of the glass window 10. The display screen 12 and the control panel 11 are connected to the data switch 2. A sealing rubber is also provided between the cover plate 6 and the explosion-proof cabinet 1. A main switch 13 is also provided inside the explosion-proof cabinet 1. The main switch 13 can control the circuit of the entire device, and the control panel 11 can control the display screen 12. Since the equipment is often used in special flammable and explosive environments, the display screen 12 is isolated by the glass window 10 to prevent electric sparks from spreading outward and causing larger accidents when the display screen 12 burns.

[0026] During use of the present invention, the explosion-proof cabinet 1 is fixed to the wall mounting position with the assistance of the fixing frame 5, the data switch 2 and the adapter 4 are installed, and the internal circuits of the equipment are installed and arranged. After the equipment installation and debugging are completed, the main switch 13 is turned on, and then, the cover plate 6 is covered on the explosion-proof cabinet 1 with the assistance of the handle 8 and the hinge 9, and the cover plate 6 is connected and fixed to the explosion-proof cabinet 1 with the assistance of the fixing bolts and nuts 7.

[0027] During daily use of the device, the control panel 11 can be used to control the display screen 12, thereby operating the device. During the use of the device, if the internal data switch 2 fails due to excessive voltage or other problems, thereby causing circuit sparks or combustion, the explosion-proof cabinet 1 and the cover 6 can be used to isolate the sparks and combustion phenomena, thereby preventing the internal sparks or combustion phenomena from spreading outward and causing larger accidents, thereby improving the safety of the device.

[0028] At the same time, since the equipment is often used in special flammable and explosive environments, where there is dust or flammable and explosive items, the display screen 12 is isolated by the glass window 10 to prevent electric sparks from spreading outward and causing greater accidents when the display screen 12 burns.

[0029] After the explosion-proof cabinet 1 and the cover plate 6 are connected and fixed by fixing bolts and nuts 7, the internal space of the explosion-proof cabinet 1 is closed. The data switch 2 generates heat during use. As the heat accumulates, the probability of failure of the data switch 2 increases. Due to the limitations of the equipment's operating environment, a conventional explosion-proof cabinet 1 is provided with a cooling fan, which will cause the explosion-proof performance of the equipment to be lost. In addition, once the explosion occurs due to the high temperature inside the explosion-proof cabinet 1, the data in the data switch 2 is also easily damaged. Continuous power supply will also aggravate the explosion. In order to solve the above problems: like Figures 1 to 6 As shown, an auxiliary regulating device 3 is provided at the lower end of the explosion-proof cabinet 1, and a circulating pump is also provided outside the explosion-proof cabinet 1, which is connected to the auxiliary regulating device 3. A temperature sensor is provided inside the explosion-proof cabinet 1. With the assistance of the circulating pump, the treated cooling water is passed into the auxiliary regulating device 3, thereby achieving a cooling effect on the inside of the explosion-proof cabinet 1. The temperature inside the explosion-proof cabinet 1 is monitored in real time with the assistance of the temperature sensor.

[0030] The auxiliary adjustment device 3 includes an adjustment plate 301, which is provided with a through hole 302. A shell 303 is provided on the outside of the adjustment plate 301, and an opening 304 is provided on the shell 303 to match the through hole 302. A connector 305 is also provided on the side end of the adjustment plate 301. During the lateral movement of the adjustment plate 301, the cooling water can only pass through the through hole 302 and the opening 304 when the through hole 302 and the opening 304 overlap. The degree of overlap controls the amount of cooling water passing through them. After the adjustment plate 301 moves to a set distance, if the adjustment plate 301 continues to move, the adjustment plate 301 will push the connector 305 to move.

[0031] The lower end of the explosion-proof cabinet 1 is provided with holes that match the outer shell 303, and the outer shell 303 and the explosion-proof cabinet 1 are welded and sealed. The lower end of the explosion-proof cabinet 1 is provided with holes that match the outer shell 303, and the outer shell 303 and the explosion-proof cabinet 1 are welded and sealed. During the installation of the outer shell 303, the upper part is first welded and sealed in the corresponding holes of the explosion-proof cabinet 1, and then the various components are installed in the upper outer shell 303. After that, the lower part of the outer shell 303 is welded and sealed again to achieve the installation of the internal components of the outer shell 303.

[0032] The adjustment plate 301 slides laterally in the cavity 310. A driving cylinder 311 is provided in the cavity 310. A liquid that is easily expanded when heated is provided in the driving cylinder 311. The output rod of the driving cylinder 311 is connected to the side end of the adjustment plate 301. The cavity 310 is also provided with an electric push rod 312 at the position of the driving cylinder 311. The output end of the electric push rod 312 is located at the side end of the adjustment plate 301. When the temperature in the explosion-proof cabinet 1 rises, the liquid that is easily expanded when heated in the driving cylinder 311 is expanded, so that the output rod of the driving cylinder 311 can push the adjustment plate 301 to move. After the electric push rod 312 is started, the output end of the electric push rod 312 can also actively push the adjustment plate 301 to move. The position of the adjustment plate 301 is adjusted in a passive and active manner, thereby indirectly controlling the amount of cooling water passing through, thereby indirectly controlling the cooling effect.

[0033] Connectors 306 are provided at the upper and lower ends of the opening 304. Circulation pipes 307 are provided on the two upper connectors 306. The two lower connectors 306 are connected to the inlet and outlet liquid pipes of the circulation pump. The circulation pipe 307 is bent in an S shape. The circulation pump serves as a driving force to make the cooling water flow. After the through hole 302 coincides with the opening 304, the cooling water will enter the circulation pipe 307. Then, by utilizing the principle of heat exchange, as the cooling water circulates, the heat in the explosion-proof cabinet 1 is brought out, thereby achieving the effect of cooling the interior of the explosion-proof cabinet 1.

[0034] The housing 303 is provided with wiring holes 308, and wiring connectors 309 are inserted into the wiring holes 308 at the upper and lower ends. The upper end wiring connector 309 is connected to the data switch 2 with the assistance of the adapter 4. The connector 305 is located between the two wiring connectors 309 at the upper and lower ends. The two wiring connectors 309 at the upper and lower ends are connected through the connector 305. After the connector 305 is pushed by the adjustment plate 301, the connector 305 and the wiring connector 309 will be misaligned, thereby causing the connection between the two to be disconnected, thereby cutting off the power to the data switch 2. On the one hand, it reduces the aggravation of combustion and explosion caused by current short circuit, and on the other hand, it avoids electric shock caused by workers' misoperation of fire extinguishing, thereby improving the safety of equipment use.

[0035] A damping cylinder 313 is disposed within cavity 310 at the side of connector 305. The output end of damping cylinder 313 is connected to connector 305. Damping cylinder 313 is located on the side of connector 305 away from adjustment plate 301. Due to the presence of damping cylinder 313, when the heat-expandable liquid within drive cylinder 311 expands due to heat, the output end of drive cylinder 311 pushes adjustment plate 301 to move. However, when adjustment plate 301 contacts connector 305, the resistance of damping cylinder 313 prevents drive cylinder 311 from pushing adjustment plate 301 alone. In other words, passive adjustment cannot meet the requirements of powering off the device.

[0036] A wiring slot 314 is provided on one side of the wiring head 309 near the connector 305, and a wiring protrusion 315 is provided on the connector 305 to match the wiring slot 314. When the connector 305 is not moving, the wiring protrusion 315 and the wiring slot 314 are interlocked. When the connector 305 is moved, the wiring protrusion 315 and the wiring slot 314 are no longer interlocked, thereby achieving circuit connection and disconnection between the upper and lower wiring heads 309.

[0037] During use of the present invention, heat is inevitably generated when the data switch 2 in the device is in operation. In the initial state, the through hole 302 on the adjustment plate 301 overlaps with the opening 304 by one quarter. When the device is in operation, the circulation pump will also operate synchronously, allowing cooling water to pass through the opening 304 and the through hole 302 into the circulation pipe 307. Then, using the principle of heat exchange, as the cooling water circulates, the heat in the explosion-proof cabinet 1 is brought out, thereby achieving the effect of cooling the interior of the explosion-proof cabinet 1.

[0038] As the data switch 2 operates for a long time, its heat generation increases, causing the temperature inside the explosion-proof cabinet 1 to rise. As the temperature inside the explosion-proof cabinet 1 rises, the liquid in the drive cylinder 311, which is easily expanded when heated, will expand due to the heat, causing the output end of the drive cylinder 311 to move laterally against the adjustment plate 301. When the adjustment plate 301 moves laterally, the overlap between the through hole 302 and the opening 304 reaches one-half, thereby increasing the flow rate of the cooling water in the circulation pipe 307 and enhancing the cooling effect of the circulation pipe 307.

[0039] When the overlap between the opening 304 and the through hole 302 reaches one-half, the side end of the adjustment plate 301 contacts the side end of the connector 305. Then, even if the temperature continues to rise, due to the resistance of the damping cylinder 313, the lateral movement of the adjustment plate 301 can no longer be driven by the volume expansion of the heated and easily expansive liquid in the drive cylinder 311. At this time, the device begins to intervene in active adjustment. That is, when the overlap between the opening 304 and the through hole 302 reaches one-half, the detection value of the temperature sensor is a. When the detection value of the temperature sensor is greater than a, the electric push rod 312 starts to be powered on.

[0040] Since there is a distance between the adjustment plate 301 and the output end of the electric push rod 312 at this time, after the electric push rod 312 is started, during the period when its output end moves to contact the adjustment plate 301, if the detection value of the temperature sensor gradually decreases to less than a, the electric push rod 312 will pass a reverse current to restore the original state, thereby avoiding abnormal operation of the data switch 2 caused by power failure.

[0041] If, after the electric push rod 312 is started, the output end of the electric push rod 312 moves and contacts the adjustment plate 301, and the detection value of the temperature sensor continues to rise, it indicates that an abnormality has occurred in the explosion-proof cabinet 1, and there is a risk of fire or explosion. As the electric push rod 312 continues to operate, the output end of the electric push rod 312 will push the adjustment plate 301 to continue moving. On the one hand, the overlap between the opening 304 and the through hole 302 continues to increase, so that the flow rate of cooling water in the circulation pipe 307 continues to increase, that is, the cooling effect continues to be strengthened, achieving a stronger cooling effect inside the explosion-proof cabinet 1. On the other hand, the movement of the adjustment plate 301 will push the connector 305 to overcome the action of the damping cylinder 313 and move. After the connector 305 moves, the wiring protrusion 315 and the wiring slot 314 are misaligned, thereby disconnecting the wiring connectors 309 at the upper and lower ends, thereby disconnecting the circuit of the data switch 2 and protecting the data switch 2.

[0042] If the detection value of the temperature sensor continues to rise and reaches b after the above measures are taken, it indicates that there is combustion inside the explosion-proof cabinet 1, and multiple spray pipes are provided on the circulation pipe 307, and a pressure valve is provided in the spray pipe. When the detection value of the temperature sensor rises to b, the equipment will control the output end of the electric push rod 312 to extend to the limit distance. At this time, the opening 304 and the through hole 302 completely coincide with each other. Therefore, the cooling water flow in the circulation pipe 307 reaches the maximum, that is, the pressure condition for the pressure valve to open is reached, and the cooling water in the circulation pipe 307 is sprayed outward through the spray pipe. By spraying cooling water outward, the combustion inside the explosion-proof cabinet 1 is suppressed, thereby improving the safety of the equipment.

[0043] Since the cooling water has been treated, its conductivity disappears. Therefore, when the sprayed cooling water acts on the internal components of the explosion-proof cabinet 1, the damage to the components is reduced. At the same time, when the values ​​of the temperature sensor reach a and b, the corresponding flashing lights and buzzing phenomena in the main control room respectively correspond to the main control room staff to remind the main control room staff of abnormal equipment operation.

[0044] The main functions achieved by the present invention are as follows: by providing components such as the adjustment plate 301, the connector 305, the drive cylinder 311, and the electric push rod 312, the data switch 2 generates heat during operation. Under the action of the heated and easily expanded liquid in the drive cylinder 311, the adjustment plate 301 is pushed, thereby increasing the overlap between the opening 304 and the through hole 302, and increasing the cooling water flow in the circulation pipe 307 to enhance the cooling effect. However, as the temperature continues to rise, due to the resistance of the damping cylinder 313, passive cooling can no longer meet the requirements, and the active temperature reduction regulation of the equipment begins to intervene. That is, the electric push rod 312 is activated according to the detection of the temperature sensor, and the overlap between the opening 304 and the through hole 302 is further increased. At the same time, the adjustment plate 301 will push the connector 305 to move, causing the wiring protrusion 315 and the wiring slot 314 to be misaligned, thereby disconnecting the wiring heads 309 at the upper and lower ends, thereby disconnecting the circuit of the data switch 2 and protecting the data switch 2. When the temperature sensor detects the presence of an open flame in the explosion-proof cabinet 1, the device will control the output end of the electric push rod 312 to extend to the limit distance, and the opening 304 and the through hole 302 will completely overlap. Therefore, the cooling water flow in the circulation pipe 307 reaches the maximum, that is, the pressure condition for the pressure valve to open is reached, and the cooling water in the circulation pipe 307 is sprayed outward through the spray pipe. By spraying the cooling water outward, the combustion inside the explosion-proof cabinet 1 is suppressed.
