Description

Technical Field

[0001] This invention belongs to the field of explosion-proof terminal technology, and specifically relates to an explosion-proof terminal with monitoring function. Background Technology

[0002] Explosion-proof terminals are specialized electronic devices designed for flammable and explosive hazardous environments (such as coal mines, petrochemical plants, gas stations, and hazardous chemical warehouses). Their core features include explosion-proof structural design (such as flameproof, intrinsically safe, and increased safety) and authoritative explosion-proof certifications (such as domestic GB 3836 and international IECEx / ATEX) to prevent electrical sparks, high temperatures, and static electricity generated during operation from igniting surrounding flammable and explosive media (gas, oil, dust, etc.). Simultaneously, they meet the data interaction, communication, and control needs of industrial scenarios. Explosion-proof terminals with monitoring functions integrate data acquisition, environmental monitoring, status sensing, and communication transmission, making them key terminal devices for achieving safety monitoring, data traceability, and remote management in hazardous industrial environments.

[0003] Most existing explosion-proof terminals with monitoring functions use fan cooling for cooling. During peak operation, a large amount of Joule heat is generated. The single air cooling method may cause the equipment to not cool down in time, which will lead to equipment damage and greatly reduce its service life. In addition, the explosion-proof upper shell and explosion-proof lower shell are connected by screws, which makes maintenance very inconvenient. Summary of the Invention

[0016] The beneficial effects of this invention are as follows:

[0017] 1. The present invention can form a cooling layer outside the assembly table through the cooling chamber in the lower shell, which helps the cooling water to keep the lower shell in a cooling state. In the cooling state, the lower shell can cool the hot air flowing into it, and the air release channel and air intake channel can transfer some of the hot air in the lower shell to the cooling water. After the hot air is cooled by the cooling water, it is released and cools the gas around the lower shell again, keeping the gas drawn into the lower shell at a low temperature and enhancing the cooling function of the lower shell.

[0018] 2. When disassembling the explosion-proof upper shell, pressing the concave pressure block causes the two sides of the concave pressure block to press against the two wedge-shaped blocks. Under the action of the inclined plane, the wedge-shaped blocks move closer together. Then, with the cooperation of the L-shaped connecting block and the movable rod, the plug-in block is pulled away from the plug-in interface. At this time, the spring contracts, the elastic telescopic column shortens, and the explosion-proof upper shell and explosion-proof lower shell are unlocked, allowing the explosion-proof upper shell to be removed for internal inspection of the explosion-proof lower shell. When assembling the explosion-proof upper shell, pressing the concave pressure block... The wedge blocks on both sides are pressed together by the inclined plane, causing them to move closer to each other. Then, with the cooperation of the L-shaped connecting block and the movable rod, the plug-in block is pulled into the slide. At this time, the spring contracts and the elastic telescopic column shortens, allowing the explosion-proof upper shell to be placed into the assembly port. The concave pressure block is released, and with the cooperation of the spring, the wedge block returns to its original position and is inserted into the plug-in port. The elastic telescopic column returns to its original position, and then the concave pressure block returns to its original position. At this time, the explosion-proof upper shell and the explosion-proof lower shell are assembled, which is very convenient to use and facilitates the maintenance of the equipment.

[0034] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the described embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0035] Please see Figures 1-12This invention proposes an explosion-proof terminal with monitoring function, comprising an anti-slip base 1, an explosion-proof lower shell 2 mounted on the upper end of the anti-slip base 1, the explosion-proof lower shell 2 being a concave square shell structure, a concave cooling chamber 3 reserved in the explosion-proof lower shell 2, an assembly port 21 reserved at the upper end of the explosion-proof lower shell 2, an explosion-proof upper shell 4 embedded in the assembly port 21, the explosion-proof upper shell 4 and the explosion-proof lower shell 2 being connected by a locking member 6, an assembly platform 41 fixedly connected at the lower end of the explosion-proof upper shell 4, the assembly platform 41 being equipped with electronic components such as a controller, sensor and power supply (not shown in the figure, all of which are prior art and will not be described in detail here), and a display screen (not shown in the figure, all of which are prior art and will not be described in detail here) mounted on the outer wall of the explosion-proof lower shell 2. During assembly, the assembled assembly platform 41 and the explosion-proof upper shell 4 are embedded into the explosion-proof lower shell 2 through the assembly port 21, and the cooling chamber 3 is used to cool the hot air in the explosion-proof lower shell 2.

[0036] Multiple heat conduction channels 31 are fixedly connected to the inner surface of the cooling chamber 3. Both sides of the heat conduction channels 31 pass through the explosion-proof lower shell 2. The multiple heat conduction channels 31 are divided into two rows and are arranged at equal intervals. One side of the explosion-proof lower shell 2 has a pair of mirror-shaped air inlets 22. Multiple equally spaced support platforms 23 are fixedly connected to the inner surface of the air inlets 22. The support platforms 23 and the heat conduction channels 31 are paired one-to-one. A miniature fan 24 is fixedly connected to the support platform 23. When the gas inside the explosion-proof lower shell 2 heats up, the cooling water installed in the cooling chamber 3 can cool the explosion-proof lower shell 2 to prevent the explosion-proof lower shell 2 from overheating. When the cooling water in the cooling chamber 3 heats up, the cooling water can be cooled through the heat conduction channels 31 to ensure the cooling function of the cooling water. The support platform 23 is used to assemble the miniature fan 24. The miniature fan 24 can enhance the heat removal function of the heat conduction channels 31.

[0037] A movable opening 32 is provided on the lower wall of the refrigeration chamber 3. Multiple engagement blocks 33 are fixedly connected to the inner surface of the movable opening 32. An A-type movable platform 34 is installed in the refrigeration chamber 3. The lower end of the A-type movable platform 34 is movably connected to the movable opening 32. A rotating disk 35 is screwed onto the lower end of the A-type movable platform 34 within the movable opening 32. Multiple teeth are provided on the outer circumferential surface of the rotating disk 35 and engage with the engagement blocks 33. A movable cylinder 36 is clamped onto the outer circumferential surface of the heat conduction channel 31. The movable cylinders 36 on the outer surfaces of the multiple equally spaced heat conduction channels 31 are fixedly connected via connecting platforms. The multiple fixed movable cylinders 36 are fixedly connected to the A-type movable platform 34. A rotating cylinder 37 is screwed onto one side of the movable cylinder 36. The surface is fixed with a baffle blade. Threaded openings are reserved on the outer circumference of the heat conduction channel 31 and the inner surface of the rotating cylinder 37. A motor is fixed in the A-moving platform 34. The motor drives the rotating disk 35 to rotate back and forth. Through the cooperation of the rotating disk 35 and the biting block 33, the A-moving platform 34 can be driven to move back and forth in the movable opening 32. Through the movement of the A-moving platform 34, the movable cylinder 36 and the rotating cylinder 37 can be driven to move back and forth along the corresponding heat conduction channel 31. During the movement of the rotating cylinder 37, the threaded openings on the inner surface of the rotating cylinder 37 and the outer surface of the heat conduction channel 31 can make the rotating cylinder 37 rotate and drive the baffle blade to rotate. The rotation of the baffle blade can turbulent the cooling water, making the cooling water move and enhancing the heat removal function.

[0038] The explosion-proof lower shell 2 has installation openings 5 ​​on both sides. Each pair of installation openings 5 ​​is located at the upper end of both sides of the cooling chamber 3. The lower end of the installation opening 5 has multiple through holes 51. The through holes 51 are connected to the cooling chamber 3. A baffle plate 52 is embedded in the installation opening 5. A sponge block 53 is embedded on the side of the baffle plate 52 that is close to the corresponding installation opening 5. The installation opening 5 is used to assemble the sponge block 53. When the cooling water in the cooling chamber 3 is heated, some water will turn into gaseous water. The gaseous water will rise and pass through the through holes 51 into the installation opening 5. The gaseous water that has moved into the installation opening 5 is absorbed by the sponge block 53. After the sponge block 53 absorbs a certain amount of cooling water, the baffle plate 52 is removed and replaced with a new sponge block 53. The replaced sponge block 53 can be reused after being dehydrated.

[0039] An arched receiving shell 54 is fixed to both sides of the explosion-proof lower shell 2 and at the bottom of the placement opening 5. A water inlet 55 is reserved on the inner surface of the receiving shell 54. The water inlet 55 and the cooling chamber 3 are connected to each other. A rubber sheet 56 is embedded in the water inlet 55. The receiving shell 54 is used to hold the excess cooling water that the sponge block 53 has not absorbed. After the receiving shell 54 holds the cooling water, the cooling water can be transferred back to the cooling chamber 3 through the water inlet 55 by removing the rubber sheet 56. The receiving shell 54 assists the water inlet 55 in making it easier to fill the cooling chamber 3 with cooling water.

[0040] A pair of mirror-mounted concave venting channels 25 are fixed to the inner surface of the explosion-proof lower shell 2. The venting channels 25 pass through the explosion-proof lower shell 2 and extend into the cooling chamber 3. A heat removal chamber 42 is reserved in the explosion-proof upper shell 4. A concave suction channel 43 is fixed to the heat removal chamber 42. A B miniature fan 44 is fixed to the suction channel 43. Both sides of the suction channel 43 pass through the explosion-proof upper shell 4. The side of the venting channel 25 that is farther from the cooling chamber 3 is embedded in the side of the suction channel 43. When the explosion-proof upper shell 4 is embedded in the assembly port 21, the venting channel 25 and the corresponding suction channel 43 will be embedded in each other. When the explosion-proof terminal is working, the B miniature fan 44 is rotated to draw the hot air formed in the explosion-proof lower shell 2 into the venting channel 25. The hot air flowing into the venting channel 25 flows into the cooling chamber 3 with the continuous cooperation of the B miniature fan 44, which can prevent the hot air from accumulating in the explosion-proof lower shell 2.

[0041] A movable opening 38 is provided on the inner surface of the cooling chamber 3. A movable platform 39 (B) is movably installed in the movable opening 38. The side of the movable platform 39 outside the movable opening 38 is fixedly connected to a telescopic channel 310. One side of the telescopic channel 310 is fixedly connected to the side of the venting channel 25 inside the cooling chamber 3. The side of the telescopic channel 310 furthest from the venting channel 25 is fixedly connected to a concave movable channel 311. The hot air that moves into the venting channel 25 flows through the telescopic channel 310 and the movable channel 311 and finally into the cooling water in the cooling chamber 3. The hot air is cooled by the cooling water. The movable platform 39 can move linearly under electric drive. The movable platform 39 can extend or retract the telescopic channel 310 and simultaneously move the movable channel 311 vertically in the cooling chamber 3. A sensor is mounted on the outer surface of the movable channel 311, which can automatically adjust according to the liquid level of the cooling water in the cooling chamber 3, so that the side of the movable channel 311 furthest from the telescopic channel 310 is always in the cooling water.

[0042] Multiple obliquely arranged air inlets 26 are reserved on both sides of the outer surface of the explosion-proof lower shell 2. The air inlets 26 pass through the explosion-proof lower shell 2. A variable plate 27 is installed on one side of the outer surface of the explosion-proof lower shell 2. The mounting point of the variable plate 27 is the same as the reserved point of the air inlet 26. A pair of mirror-shaped linear push rods 28 are fixedly connected in the explosion-proof lower shell 2. The movable end of the linear push rod 28 passes through the explosion-proof lower shell 2 and is fixedly connected to the variable plate 27. The air inlets 26 are used to allow air to enter and exit the explosion-proof lower shell 2. The linear push rods 28 can pull the variable plate 27 to move back and forth by extending and contracting. The back and forth movement of the variable plate 27 assists the air inlets 26 to compress the hot air in the explosion-proof lower shell 2, which can accelerate the release of hot air.

[0043] The locking component 6 includes a connector 61 pre-installed on the side wall of the assembly opening 21 and a slide 62 pre-installed in the crossbar of the explosion-proof upper shell 4. Fixed blocks 63 are fixed to both sides of the slide 62. A movable rod 64 is movably installed in the fixed block 63. A plug-in block 65 is fixed to the outward-facing side of the movable rod 64. The outward-facing side of the plug-in block 65 can be inserted into the connector 61. A spring 66 is fixed between the plug-in block 65 and the fixed block 63. The spring 66 is clamped to the outside of the movable rod 64. The other side of the rod 64 is fixedly connected to an L-shaped connecting block 67, and the other side of the L-shaped connecting block 67 is fixedly connected to a wedge block 68. The inclined surface of the wedge block 68 is set from top to bottom outward. A through pressing port 69 is reserved in the center of the upper end of the slide 62. A concave pressing block 610 is movably installed in the pressing port 69. The two sides of the concave pressing block 610 are in contact with the inclined surface of the wedge block 68 respectively. The center of the concave pressing block 610 is fixedly connected to the bottom wall of the slide 62 by an elastic telescopic column 611.

[0044] When disassembling the explosion-proof upper shell 4 is required, press the concave pressure block 610. The two sides of the concave pressure block 610 press against the two wedge blocks 68. Under the action of the inclined plane, the wedge blocks 68 move closer to each other. Then, with the cooperation of the L-shaped connecting block 67 and the movable rod 64, the plug-in block 65 is pulled away from the plug-in interface 61. At this time, the spring 66 contracts, the elastic telescopic column 611 shortens, and the explosion-proof upper shell 4 and the explosion-proof lower shell 2 are unlocked, so the explosion-proof upper shell 4 can be removed for inspection of the interior of the explosion-proof lower shell 2. When assembling the explosion-proof upper shell 4 is required, press the concave pressure block 610. The wedge blocks 68 on both sides of the 10 are pressed together by the inclined plane, causing the wedge blocks 68 to move closer to each other. Then, with the cooperation of the L-shaped connecting block 67 and the movable rod 64, the traction plug 65 is pulled into the slide 62. At this time, the spring 66 contracts and the elastic telescopic column 611 shortens, putting the explosion-proof upper shell 4 into the assembly port 21. The concave pressure block 610 is released. With the cooperation of the spring 66, the wedge blocks 68 are reset and inserted into the plug interface 61. The elastic telescopic column 611 is reset, and then the concave pressure block 610 is pulled to reset. At this time, the explosion-proof upper shell 4 and the explosion-proof lower shell 2 are assembled, which is very convenient to use.

[0045] The handle 612 is fixedly connected to the center of the upper end of the explosion-proof upper shell 4. The handle 612 is located directly above the concave pressure block 610, and the projected area of ​​the handle 612 is larger than the upper surface area of ​​the handle 612.

[0046] The handle 612 not only facilitates the carrying and movement of the device, but also makes it easy to pull the explosion-proof upper shell 4 away from the explosion-proof lower shell 2 when disassembling it. It also shields the concave pressure block 610 to prevent accidental contact that could cause the concave pressure block 610 to move downwards and lead to the disassembly of the explosion-proof upper shell 4 and the explosion-proof lower shell 2, thus providing a certain degree of protection.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
