Description

Technical Field

[0001] This invention relates to the technical field of chassis manufacturing, and in particular to a data acquisition chassis disclosed herein. Background Technology

[0002] With the development of information technology and the continuous improvement of management level, information-based production management has become an important means of production management in the manufacturing industry. Traditional factory equipment is difficult to collect data effectively, which causes inconvenience to factory management and can easily reduce industrial production efficiency. Industrial production equipment data acquisition uses various communication methods to access different devices and sensors to collect equipment data in industrial production, thereby building the data foundation of the industrial Internet platform.

[0003] A digital enclosure is a chassis that integrates components for digital data acquisition. The function of a digital enclosure power distribution cabinet is to collect information data from equipment in industrial production. If a short circuit or leakage occurs in the transformer module within the digital enclosure, it can provide power-off protection. Because the digital enclosure contains a large number of components, the heat generated by these electrical components dissipates into the enclosure, causing the internal temperature to rise.

[0004] Regarding the aforementioned technologies, the data acquisition chassis contains a large number of components, which are prone to short circuits and leakage. Since short circuits and leakage can lead to spontaneous combustion of the components inside the data acquisition chassis, fire extinguishing within the data acquisition chassis is a crucial aspect. Summary of the Invention

[0005] To improve the fire extinguishing capabilities within a data acquisition chassis, this application provides a data acquisition chassis.

[0006] This application provides a data acquisition chassis, which adopts the following technical solution:

[0007] A data acquisition chassis includes a digitizing chassis and a fire extinguishing component disposed on the side wall of the digitizing chassis. The digitizing chassis houses a transformer module and a data acquisition module. The fire extinguishing component includes a dry powder fire extinguisher mounted on the side wall of the digitizing chassis, a heat dissipation cylinder rotatably mounted inside the digitizing chassis, and several arc-shaped strips mounted on the periphery of the heat dissipation cylinder. The heat dissipation cylinder is connected to the dry powder fire extinguisher via a dry powder conduit. The arc-shaped strips have cavities inside, and several dry powder spray nozzles are located on the surface of the arc-shaped strips near the digitizing chassis.

[0008] By adopting the above technical solution, when a fire occurs due to an internal short circuit in the data acquisition module or transformer module, the dry powder fire extinguisher enters the arc-shaped strip through the dry powder conduit and heat dissipation cylinder. The dry powder extinguishing agent in the dry powder fire extinguisher is sprayed towards the inside of the data acquisition module and transformer module through several dry powder spray nozzles on the arc-shaped strip to extinguish the fire.

[0009] Optionally, the digital chassis is equipped with a gas filling component for rotating the arc-shaped plate. The gas filling component includes a heptafluoropropane fire extinguisher installed on the side wall of the digital chassis, a hollow ring I fixedly installed at the end of the heat dissipation cylinder, a hollow ring II rotatably installed at the end of the hollow ring I, several arc-shaped conduits fixed to one side of the hollow ring, and a fire nozzle fixed to the end of the arc-shaped conduits away from the hollow ring I. The arc-shaped conduits and the hollow ring I are both connected to the hollow ring II. The several arc-shaped conduits are all bent in the same clockwise direction. The hollow ring II is connected to the heptafluoropropane fire extinguisher through a gas conduit.

[0010] By adopting the above technical solution, when a fire occurs due to an internal short circuit in the data acquisition module or transformer module, heptafluoropropane gas is ejected through the fire nozzles on the arc-shaped ducts. The ejected gas generates a thrust that drives several arc-shaped ducts to rotate. These ducts then drive several arc-shaped strips to rotate synchronously. The rotating arc-shaped strips evenly spray dry powder extinguishing agent onto the surface of the components inside the data acquisition module and transformer module. The ejected heptafluoropropane gas can reduce the oxygen content in the air of the digital chassis, thereby minimizing the risk of air entering the digital chassis through the heat dissipation channels and contributing to combustion.

[0011] Optionally, the outer wall of the digital chassis is provided with a heat dissipation component for heat dissipation. The heat dissipation component includes a gas purification device and a booster pump located on the outer wall of the digital chassis. The gas purification device is connected to the inlet port of the booster pump, and the gas conduit is connected to the outlet port of the booster pump. An electromagnetic valve is provided between the gas conduit and the booster pump.

[0012] By adopting the above technical solution, during the daily operation of the digital chassis, the booster air pump and solenoid valve are activated synchronously. First, air flows into the air inlet of the booster air pump after being filtered by the gas purification equipment. Then, the air flows into the inside of the hollow ring I through the gas duct and the second hollow ring. The gas inside the first hollow ring is ejected through the fire nozzles on the arc-shaped duct. The ejected gas generates a counter-thrust force that drives several arc-shaped ducts to rotate. These arc-shaped ducts drive several arc-shaped plates to rotate synchronously. At this time, the arc-shaped plates are similar to a fan structure, increasing the airflow inside the digital chassis and thus dissipating heat.

[0013] Optionally, the digital chassis has heat dissipation slots on its two opposite side walls, and the digital chassis has sealing components through the heat dissipation slots. The sealing components include several rotating shafts that are rotatably mounted on the two opposite side walls of the digital chassis, and several strip-shaped louvers mounted on the periphery of the rotating shafts.

[0014] By adopting the above technical solution, the rotating shaft drives several strip louvers to rotate synchronously, and the side walls of two adjacent strip louvers are tightly fitted together, thereby achieving the effect of a closed chassis structure for the digital chassis.

[0015] Optionally, the digital chassis is provided with a synchronization component for driving the synchronous rotation of several strip-shaped louvers. The synchronization component includes two synchronous straight rods respectively rotatably mounted on two opposite side walls of the digital chassis, synchronous worm gears located at the ends of several rotating shafts, and several synchronous worms located around the synchronous straight rods; the synchronous worm gears are meshed with the corresponding synchronous worms.

[0016] By adopting the above technical solution, due to the meshing of the synchronous worm gear and the synchronous worm, the drive motor drives several rotating shafts to rotate synchronously through the synchronous straight rod, thereby achieving the effect of the rotating shafts driving several strip louvers to rotate synchronously.

[0017] Optionally, the outer wall of the digital chassis is provided with a transmission component, which includes a synchronous pulley installed at the end of the synchronous rod, a synchronous belt sleeved around the two synchronous pulleys, and a drive motor installed on the outer wall of the digital chassis; the drive motor is connected to one of the synchronous rods.

[0018] By adopting the above technical solution, the drive motor drives the synchronous pulley on one of the synchronous rods to rotate, and the rotating synchronous pulley drives the other synchronous rod to rotate, thereby realizing that when the drive motor starts, it drives the two synchronous rods to rotate synchronously through the synchronous pulley and the synchronous belt.

[0019] Optionally, the digital enclosure is equipped with a pressure relief component for reducing air pressure. The pressure relief component includes a piston-type pressure relief valve fixedly installed on the top of the digital enclosure, and the piston-type pressure relief valve is connected to the gas purification equipment.

[0020] By adopting the above technical solution, the digital chassis is filled with heptafluoropropane gas, which gradually increases the gas pressure inside the digital chassis, thereby activating the piston-type pressure relief valve and purifying the gas through the gas purification equipment.

[0021] Optionally, the digital enclosure is equipped with sensing components for fire monitoring. The sensing components include a fire sensor located inside the digital enclosure, a fire alarm light located on the outer wall of the digital enclosure, and electrically controlled valves installed at the ports of the dry powder fire extinguisher and the heptafluoropropane fire extinguisher. The fire alarm light and the electrically controlled valves are electrically connected to the fire sensor.

[0022] By adopting the above technical solution, when a fire occurs due to an internal short circuit in the data acquisition module or transformer module, the fire sensor inside the digital chassis controls the fire alarm light to activate, and the fire alarm light flashes to alert personnel that there is a fire inside the digital chassis; the fire sensor controls the electric control valves on the dry powder fire extinguisher and the heptafluoropropane fire extinguisher to activate, and the dry powder extinguishing agent is sprayed into the digital chassis through several fire nozzles, and the heptafluoropropane gas in the heptafluoropropane fire extinguisher is sprayed out through the fire nozzle on the arc-shaped duct.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. When a fire occurs due to an internal short circuit in the data acquisition module or transformer module, heptafluoropropane gas is ejected through the fire nozzles on the arc-shaped ducts. The ejected gas generates a thrust that drives several arc-shaped ducts to rotate. These arc-shaped ducts then drive several arc-shaped strips to rotate synchronously. The rotating arc-shaped strips evenly spray dry powder extinguishing agent onto the surface of the components inside the data acquisition module and transformer module. The ejected heptafluoropropane gas minimizes the risk of air entering the digital chassis through the heat dissipation channels and contributing to combustion.

[0025] 2. During the daily operation of the digital chassis, the booster air pump and solenoid valve start synchronously. First, air flows into the air inlet of the booster air pump through the filter of the gas purification equipment. Then, the air flows into the inside of the hollow ring one through the gas duct and the second hollow ring. The gas inside the first hollow ring is sprayed out through the fire nozzle on the arc-shaped duct. The sprayed gas generates a counter-thrust force, which drives several arc-shaped ducts to rotate. The arc-shaped ducts drive several arc-shaped plates to rotate synchronously. At this time, the arc-shaped plates are similar to the fan structure. The arc-shaped plates increase the airflow inside the digital chassis, thereby dissipating heat.

[0026] 3. In the event of an internal short circuit and fire in the data acquisition module or transformer module, the fire sensor inside the digital enclosure activates the fire alarm light, which flashes to alert personnel that there is a fire inside the digital enclosure. The fire sensor also activates the electrically controlled valves on the dry powder fire extinguisher and the heptafluoropropane fire extinguisher, thereby enabling the dry powder extinguishing agent to be sprayed into the digital enclosure through several fire nozzles, and the heptafluoropropane gas in the heptafluoropropane fire extinguisher to be sprayed out through the fire nozzles on the arc-shaped duct.

[0033] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0034] Reference Figure 1 and Figure 2 As shown, a data acquisition chassis includes a ground-mounted digital chassis 11, which includes a power distribution cabinet 12 and a data acquisition cabinet 13 integrally formed on the top of the power distribution cabinet 12. A transformer module is fixedly installed on the inner side wall of the power distribution cabinet 12. A heat dissipation panel 14 is vertically fixedly installed on the inner bottom surface of the data acquisition cabinet 13, and a data acquisition module is fixedly installed on the front side wall of the heat dissipation panel 14. Several strip-shaped channels 15 are formed along the length of the front side wall of the heat dissipation panel 14 to facilitate airflow. Heat dissipation channels 16 are formed on the left and right side walls of the digital chassis 11, thereby enabling the components inside the power distribution cabinet 12 and the data acquisition cabinet 13 to be cooled through the heat dissipation channels 16.

[0035] Reference Figure 2 and Figure 3The left and right side walls of the digital chassis 11 are equipped with rotating shafts 17 in a horizontal direction via heat dissipation slots 16. Both ends of the rotating shafts 17 are rotatably mounted to the inner wall of the heat dissipation slots 16. Several rotating shafts 17 are arranged vertically. Strip-shaped louvers 18 are installed along the length of the rotating shafts 17, with their rotation axes coaxial with the rotation axes of the rotating shafts 17. The side walls of adjacent strip-shaped louvers 18 are tightly fitted together. The digital chassis 11 has cavities located near the two apex positions on the front side of the digital chassis 11. The ends of the rotating shafts 17 on the left and right sides of the digital chassis 11 pass through the inner sides of the two cavities. A synchronization rod 19 is vertically arranged through the cavities of the digital chassis 11, with both ends of the synchronization rod 19 rotatably mounted to the inner top and bottom surfaces of the cavities of the digital chassis 11.

[0036] Reference Figure 2-4 As shown, several rotating shafts 17 within the same heat dissipation slot 16 have synchronous worm gears 20 coaxially fixed to their front ends. Several synchronous worms 21 are coaxially fixed to the periphery of the synchronous straight rod 19, corresponding to several synchronous worm gears 20. The synchronous worm gears 20 mesh with their corresponding synchronous worms 21. A drive motor 22 is mounted on the top of the digital chassis 11, and the bottom end of the output shaft of the drive motor 22 is fixedly connected to the end of one of the synchronous straight rods 19. The bottom end of the synchronous straight rod 19 extends through the bottom of the digital chassis 11 and is coaxially fixed to a synchronous pulley 23. A synchronous belt 24 is fitted onto the outer periphery of two synchronous pulleys 23. A protective cover 25 with a circular longitudinal section is installed on the outer rear wall of the digital chassis 11. The front side wall of the protective cover 25 is connected to the rear side wall of the digital chassis 11. A suspended ring 26 is suspended on the inner periphery of the protective cover 25 by several straight strips.

[0037] Reference Figure 4 and Figure 5The outer wall of the digital chassis 11 is equipped with a dry powder fire extinguisher 30 and a heptafluoropropane fire extinguisher 31. A heat dissipation cylinder 27 is rotatably mounted on the inner circumference of the suspended ring 26, with the end of the heat dissipation cylinder 27 away from the digital chassis 11 extending out of the suspended ring 26. Four arc-shaped strips 28 are fixedly mounted on the periphery of the heat dissipation cylinder 27 around its own axis. All four arc-shaped strips 28 are bent in the same direction, and each arc-shaped strip 28 has a cavity that communicates with the heat dissipation cylinder 27. Each of the four arc-shaped strips 28 near the surface of the digital chassis 11 has a dry powder spray nozzle 29, which communicates with the cavity of the arc-shaped strip 28. Several dry powder spray nozzles 29 are provided along the path of the arc-shaped strip 28. A dry powder conduit 32 is rotatably mounted on the end of the heat dissipation cylinder 27 away from the digital chassis 11. The dry powder conduit 32 is coaxially arranged with the rotation axis of the heat dissipation cylinder 27, and the end of the dry powder conduit 32 away from the heat dissipation cylinder 27 is connected to the dry powder fire extinguisher 30.

[0038] Reference Figure 4 and Figure 5 A hollow ring 33 is coaxially fixed to the end of the heat dissipation cylinder 27 away from the digital chassis 11. A hollow ring 34 is rotatably mounted to the end of the hollow ring 33 away from the digital chassis 11. Four arc-shaped guide tubes 35 are evenly spaced around the circumference of the hollow ring 33 with its own axis as the axial direction. The four arc-shaped guide tubes 35 correspond to four arc-shaped strips 28, and the bending direction of the arc-shaped guide tubes 35 and the arc-shaped strips 28 is the same. Both the arc-shaped guide tubes 35 and the hollow ring 34 are connected to the hollow ring 33. Fire nozzles 36 are fixedly installed at the ends of the arc-shaped guide tubes 35 away from the hollow ring 33. The end of the dry powder conduit 32 away from the digital enclosure 11 passes through the inner circumference of the first hollow ring 33 and the second hollow ring 34 respectively. The end of the second hollow ring 34 away from the digital enclosure 11 is vertically fixed with a gas conduit 37. The end of the gas conduit 37 away from the second hollow ring 34 is connected to the heptafluoropropane fire extinguisher 31.

[0039] Reference Figure 2 and Figure 4The digital enclosure 11 has a fire sensor 38 installed on its inner wall for fire monitoring, and a fire alarm light 39 installed on its top. Both the dry powder fire extinguisher 30 and the heptafluoropropane fire extinguisher 31 have electrically controlled valves 40 at their ports. The fire alarm light 39 and the electrically controlled valves 40 are connected to the fire sensor 38 via power lines. A gas purification device 41 for gas purification is fixedly installed on the top of the digital enclosure 11, and a booster pump 42 is fixedly installed on its outer wall. The gas purification device 41 and the booster pump 42 are connected via straight conduits, as are the gas conduit 37 and the booster pump 42. A solenoid valve 43 is coaxially mounted on the periphery of the straight conduit, located between the gas conduit 37 and the booster pump 42. A piston-type pressure relief valve 44 for venting gas inside the digital enclosure 11 is fixedly installed on the top of the enclosure. The piston-type pressure relief valve 44 is connected to the gas purification equipment 41 via a straight conduit.

[0040] The implementation principle of a data acquisition chassis disclosed in this application is as follows: During the daily operation of the digital chassis 11, the booster air pump 42 and the solenoid valve 43 are started synchronously. First, air flows into the air inlet of the booster air pump 42 after being filtered by the gas purification device 41. Then, the air flows into the inner side of the hollow ring 33 through the gas duct 37 and the hollow ring 34. The gas inside the hollow ring 33 is ejected through the fire nozzle 36 on the arc-shaped duct 35. The ejected gas generates a counter-thrust force, which drives several arc-shaped ducts 35 to rotate. The several arc-shaped ducts 35 drive several arc-shaped plates 28 to rotate synchronously. At this time, the several arc-shaped plates 28 are similar to a fan structure, which increases the airflow inside the digital chassis 11 to dissipate heat. The digital chassis 11 collects digital information data through the data acquisition module in the data acquisition cabinet 13. The digital chassis 11 supplies power to the data acquisition module in the data acquisition cabinet 13 through the transformer module in the power distribution cabinet 12.

[0041] When a fire occurs due to an internal short circuit in the data acquisition module or transformer module, the fire sensor 38 inside the digital enclosure 11 activates the fire alarm light 39, which flashes to alert personnel that there is a fire inside the digital enclosure 11. Because the synchronous worm gear 20 and synchronous worm 21 are meshed, the drive motor 22 drives several rotating shafts 17 to rotate synchronously via the synchronous straight rod 19. The rotating shafts 17 drive several strip-shaped louvers 18 to rotate synchronously, and the sidewalls of adjacent strip-shaped louvers 18 are tightly fitted together. This achieves a closed enclosure structure for the digital enclosure 11, thereby minimizing the entry of outside air into the digital enclosure 11 through the heat dissipation slots 16 to aid combustion. The fire sensor 38 controls the activation of the electrically controlled valve 40 on the dry powder fire extinguisher 30 and the heptafluoropropane fire extinguisher 31. The dry powder fire extinguisher 30 enters the arc-shaped strip plate 28 through the dry powder conduit 32 and the heat dissipation cylinder 27, and the heptafluoropropane fire extinguisher 31 enters the arc-shaped conduit 35 through the hollow ring 1 33 and the hollow ring 2 34.

[0042] The dry powder extinguishing agent in the dry powder fire extinguisher 30 is sprayed into the data acquisition module and transformer module through several fire nozzles 36 on the arc-shaped strip 28. The heptafluoropropane gas in the heptafluoropropane fire extinguisher 31 is ejected through the fire nozzles 36 on the arc-shaped conduit 35. The ejected gas generates a thrust that drives several arc-shaped conduits 35 to rotate. These conduits 35, in turn, drive several arc-shaped strips 28 to rotate synchronously. The rotating arc-shaped strips 28 evenly spray the dry powder extinguishing agent onto the surfaces of the components in the data acquisition module and transformer module. The ejected heptafluoropropane gas reduces the oxygen content in the digital chassis 11, thus minimizing the risk of air entering the digital chassis 11 through the heat dissipation slot 16 and contributing to combustion. As the digital chassis 11 is filled with heptafluoropropane gas, the internal pressure gradually increases. The piston-type pressure relief valve 44 is activated, and the gas is purified by the gas purification device 41.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
