[0002] The packing of a reciprocating compressor is a very important component of the compressor. It is mainly used to seal the gap between the piston rod and the cylinder to prevent gas leakage. During the processing of the reciprocating compressor, under high pressure and high temperature environment, the packing needs to be equipped with a cooling system to prevent the packing ring from wearing quickly due to high temperature. At the same time, in order to avoid damage to the packing due to excessive temperature, the temperature of the packing needs to be monitored in real time.

[0003] In the prior art, the temperature measurement method for the filler is to open a temperature measuring groove on the filler and insert a platinum thermistor into the temperature measuring groove for temperature measurement. This method cannot ensure that the platinum thermistor is in contact with the inner wall of the temperature measuring groove. When the platinum thermistor is not in contact with the inner wall of the temperature measuring groove, the filler temperature cannot be quickly transmitted to the platinum thermistor. There is a certain temperature difference, which will cause the measured temperature data to be inaccurate. In addition, if the platinum thermistor is damaged, the staff will not be able to discover it in time when the single platinum thermistor is measured. Summary of the invention

DETAILED DESCRIPTION

[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0028] Reference Figures 1 to 8 The technical solution provides a monitoring mechanism, a heat conduction mechanism and a driving mechanism of an explosion-proof temperature monitoring device for a reciprocating compressor packing 12, which can achieve a more accurate temperature monitoring effect. At the same time, the temperature is displayed in real time through the platinum thermal resistor 15 and the platinum sheet 21. Multiple temperature data are compared with each other, which can facilitate the staff to find which equipment is damaged and replace it.

[0029] Furthermore, the monitoring mechanism can monitor the real-time temperature of the packing 12, which includes a shell 10, on which a compression rod 11 and a packing 12 are provided, on which a bolt 13 and a temperature measuring groove 14 are provided, the temperature measuring groove 14 is located on the end surface of the packing 12, and inside the temperature measuring groove 14 a platinum thermal resistor 15 is provided, on which a threaded block 16 is provided, and on the outer side wall of the shell 10 a monitoring part 17 is provided, through which the platinum thermal resistor 15 can be threadedly connected to the packing 12.

[0030] Furthermore, the monitoring part 17 includes a temperature display 171 and an explosion-proof junction box 172 mounted on the outer wall of the housing 10 , and the platinum thermal resistor 15 is connected to the temperature display 171 and the explosion-proof junction box 172 respectively through a power line 173 .

[0031] During use, after the reciprocating compressor has been used for a period of time, the temperature of the packing 12 will rise. In order to prevent the packing 12 from being too hot and affecting the normal operation of the compressor, the staff inserts the platinum thermal resistor 15 into the temperature measuring tank 14. When the temperature of the packing 12 rises, the real-time temperature of the packing 12 can be measured by the platinum thermal resistor 15 inside the temperature measuring tank 14 and displayed on the temperature display 171, so that the staff can understand the temperature of the packing 12 in real time and perform subsequent operations.

[0032] Furthermore, the heat conduction mechanism can speed up the heat conduction efficiency of the platinum sheet 21, so that the measurement of the temperature of the filler 12 is more accurate, including a clamping rod 20 on the platinum thermal resistor 15, the clamping rod 20 is connected with a platinum sheet 21, the platinum sheet 21 is sleeved on the clamping rod 20, the platinum sheet 21 is "L" shaped, and there is a movable space between the platinum sheet 21 and the platinum thermal resistor 15, and the platinum thermal resistor 15 has an inclined groove 22, the inclined groove 22 is located at the end away from the threaded block 16, and the number of the inclined grooves 22 is multiple, and the multiple inclined grooves 22 are evenly distributed on the outer wall of the platinum thermal resistor 15, the number of the clamping rods 20 is the same as the number of the platinum sheets 21, the number of the platinum sheets 21 is the same as the number of the inclined grooves 22, the interior of the inclined groove 22 is provided with an extrusion portion 23 and a limiting portion 24, and the platinum thermal resistor 15 is provided with a locking portion 25.

[0033] Furthermore, the extrusion portion 23 includes an extrusion block 231 inside the inclined groove 22, the contact surface between the extrusion block 231 and the inclined groove 22 is an inclined surface, the number of the extrusion blocks 231 is the same as the number of the inclined grooves 22, one end of the extrusion block 231 is connected to a slider 232, and multiple extrusion blocks 231 are all connected to a ring 233. The side wall of the platinum thermal resistor 15 is sleeved with a ring 233, and the end face of the ring 233 is provided with a slide groove 234, and the slider 232 is located inside the slide groove 234.

[0034] Furthermore, the extrusion block 231 is slidably connected to the outer wall of the platinum thermal resistor 15 , and the outer wall of the extrusion block 231 is in contact with the inner wall of the platinum sheet 21 .

[0035] Specifically, when the extrusion block 231 moves inside the chute 22 , the side of the extrusion block 231 away from the chute 22 is horizontally parallel to the inner wall of the temperature measuring chamber 14 .

[0036] During use, when the extrusion block 231 moves inside the inclined slot 22 , the extrusion block 231 can drive the slider 232 to move inside the sliding slot 234 .

[0037] Furthermore, the limiting portion 24 includes a first fixing plate 241 inside the inclined groove 22, the number of the first fixing plates 241 is two, the two first fixing plates 241 are respectively in contact with the side walls of the extrusion block 231, the first fixing plate 241 is connected to a first V-shaped plate 242, the two first V-shaped plates 242 protrude in opposite directions, the first V-shaped plate 242 is connected to a second fixing plate 243, and the second fixing plate 243 is connected to a second V-shaped plate 244.

[0038] Specifically, both sides of each platinum sheet 21 are located below the two first V-shaped sheets 242 . The first V-shaped sheets 242 can restrict the platinum sheet 21 to prevent the platinum sheet 21 from turning outward and affecting the normal insertion of the platinum sheet 21 into the temperature measuring tank 14 .

[0039] When in use, when the extrusion block 231 moves inside the inclined groove 22, with the guidance of the inclined groove 22, the extrusion block 231 gradually rises and squeezes the platinum sheet 21, so that the paddle squeezes the first V-shaped sheet 242, so that the two first V-shaped sheets 242 are close to each other, so that the platinum sheet 21 can be detached from the bottom of the first V-shaped sheet 242, and finally the side wall of the platinum sheet 21 contacts the inner wall of the temperature measuring chamber 14. At this time, when the filler 12 heats up, the temperature of the filler 12 can be quickly transferred to the platinum sheet 21, and the temperature is displayed in real time on the temperature display 171 through the platinum sheet 21.

[0040] Furthermore, the locking portion 25 includes a first thread 251 on the platinum thermal resistor 15 , and a rotating sleeve 252 is provided at the first thread 251 . The rotating sleeve 252 presses the platinum sheet 21 , so that the docking of the platinum sheet 21 and the clamping rod 20 is more stable.

[0041] During use, when a platinum sheet 21 among multiple platinum sheets 21 is damaged, the temperature measured by the corresponding platinum sheet 21 will be different from the temperatures measured by other platinum sheets 21. By rotating the rotating sleeve 252, the restriction on the platinum sheet 21 can be released and the damaged platinum sheet 21 can be replaced.

[0042] Furthermore, the driving mechanism, when the staff inserts the platinum sheet 21 into the temperature measuring tank 14, the staff can make the platinum sheet 21 fit with the inner wall of the temperature measuring tank 14, so that the temperature measurement value is more accurate, including a groove 30 on the threaded block 16, the number of the grooves 30 is two, the two grooves 30 are both arranged on the side wall of the threaded block 16, a pull rod 31 is arranged inside the groove 30, one end of the pull rod 31 is connected to the end face of the ring 233, the pull rod 31 can drive the ring 233 to slide on the side wall of the platinum thermal resistor 15, the threaded block 16 is connected to a driving part 32, and the driving part 32 is provided with a follower part 33 and a limit part 34.

[0043] Furthermore, the driving part 32 includes a driving sleeve 321 rotatably connected to the threaded block 16, a chamber 322 is arranged inside the driving sleeve 321, the chamber 322 is located between the driving sleeve 321 and the threaded block 16, a fixing ring 323 is arranged inside the chamber 322, the fixing ring 323 is threadedly connected to the inner wall of the chamber 322, and the fixing ring 323 is connected to the pull rod 31.

[0044] When in use, when the driving sleeve 321 rotates, the fixing ring 323 can move inside the chamber 322 . When the fixing ring 323 moves, it can drive the pull rod 31 to move together, and the pull rod 31 drives the ring 233 to slide on the platinum thermal resistor 15 .

[0045] Furthermore, the follower part 33 includes an arc groove 331 on the rotating sleeve 252. There are two arc grooves 331, which are evenly arranged on the outer wall of the rotating sleeve 252. One end of the arc groove 331 passes through the end surface of the rotating sleeve 252. A fixing rod 332 is arranged on the side wall of the pull rod 31.

[0046] When in use, when the pull rod 31 drives the fixed rod 332 to move, the fixed rod 332 can enter the interior of the arc groove 331. When the fixed rod 332 moves inside the arc groove 331, it can drive the rotating sleeve 252 to rotate, so that the rotating sleeve 252 releases the extrusion restriction on the platinum sheet 21, so that the platinum sheet 21 can be removed from the clamping rod 20.

[0047] Furthermore, the limiting portion 34 includes a threaded hole 341 at the middle of the driving sleeve 321 , and a threaded rod 342 is disposed inside the threaded hole 341 .

[0048] Specifically, when the fixing ring 323 moves to contact the threaded rod, the fixing rod 332 does not enter the arc groove 331. At the same time, the extrusion block 231 drives the platinum sheet 21 to contact the inner wall of the temperature measuring chamber 14, which facilitates heat conduction of the platinum sheet 21 and makes temperature measurement more accurate.

[0049] Furthermore, when the extrusion block 231 moves to the innermost part of the inclined groove 22 , the fixing ring 323 contacts the threaded rod, and the temperature data measured by the platinum thermal resistor 15 and the platinum sheet 21 are separately displayed on the temperature display 171 .

[0050] Specifically, the actual temperature of the filler 12 can be determined more accurately based on the multiple temperature data measured by the multiple platinum sheets 21 .

[0051] Working principle: In order to monitor the temperature of the packing 12 in real time, a temperature measuring groove 14 is opened on the end face of the packing 12. Before the compressor works, the staff locks the packing 12 with the bolt 13. After that, the staff inserts the platinum thermal resistor 15 with the platinum sheet 21 into the temperature measuring groove 14, and finally screws the platinum thermal resistor 15 to make the threaded block 16 threadedly connected with the packing 12. When the driving sleeve 321 contacts the packing 12, the installation of the platinum thermal resistor 15 is completed.

[0052] In order to further improve the accuracy of temperature measurement, the staff can rotate the driving sleeve 321. When the driving sleeve 321 rotates, the fixed ring 323 located inside the chamber 322 moves. When the fixed ring 323 moves, it drives the pull rod 31 to move. The pull rod 31 drives the ring 233 to move. The ring 233 drives the extrusion block 231 inside the inclined groove 22 to move together. When the extrusion block 231 moves inside the inclined groove 22, it can drive the slider 232 on the extrusion block 231 to move together, so that the slider 232 moves inside the slide groove 234. When the extrusion block 231 moves, it gradually squeezes the platinum sheet 21. When the platinum sheet 21 rises, The first V-shaped plate 242 can be squeezed to move the platinum plate 21 from the first fixed plate 241 to the second fixed plate 243. During this process, the second V-shaped plate 244 is squeezed and contracted and then recovers. The position of the platinum plate 21 is limited by the second fixed plate 243 to prevent the position of the platinum plate 21 from shifting. As the extrusion block 231 continues to move, the extrusion block 231 drives one end of the platinum plate 21 to contact the inner wall of the temperature measuring tank 14. As the extrusion block 231 continues to move, gradually, the side wall of the platinum plate 21 gradually fits with the inner wall of the temperature measuring tank 14 until the fixing ring 323 contacts the threaded rod, and the driving sleeve 321 stops rotating.

[0053] After the compressor has been used for a long time, the temperature of the packing 12 gradually rises, and the temperature is measured by the platinum sheet 21. Multiple platinum sheets 21 display the temperature measurement data through the temperature display 171. When the difference between multiple data is not large, the actual temperature of the packing 12 can be determined, which avoids the staff's inability to discover in time when a single temperature measurement data is inaccurate.

[0054] When the temperature measurement data of multiple platinum sheets 21 are different, the staff can promptly discover and identify the damaged platinum sheet 21. At this time, the staff rotates the threaded block 16 in the opposite direction to disengage the platinum thermal resistor 15 from the inside of the temperature measuring tank 14. Then, the staff removes the threaded rod from the driving sleeve 321. The staff can continue to rotate the driving sleeve 321, and the driving sleeve 321 drives the fixing ring 323 to continue to move. The fixing ring 323 drives the pull rod 31 to move, and the pull rod 31 drives the circular ring 233 and the fixing rod 332 to move together, so that the fixing rod 332 enters the inside of the arc groove 331. As the fixing rod 332 moves, the fixing rod 332 squeezes the inner wall of the arc groove 331, so that the rotating sleeve 252 rotates. Through the setting of the first thread 251, the rotating sleeve 252 can move on the side wall of the platinum thermal resistor 15 when it rotates, so that the rotating sleeve 252 does not squeeze the platinum sheet 21. At this time, the staff can remove the damaged platinum sheet 21 from the clamping rod 20. After replacing the new platinum sheet 21, the staff rotates the driving sleeve 321 in the opposite direction, so that the fixing ring 323 moves in the opposite direction, and the fixing ring 323 drives the pull rod 31, and the pull rod 31 drives the fixing rod 332 to disengage from the inside of the arc groove 331, so that the rotating sleeve 252 rotates in the opposite direction, so that the rotating sleeve 252 squeezes and fixes the position of the platinum sheet 21, and the pull rod 31 drives the extrusion block 231 to descend inside the inclined groove 22. At the same time, the extrusion block 231 drives the slider 232 to move inside the slide groove 234, and finally makes the end face of the fixing ring 323 contact the inner wall of the chamber 322. At this time, the extrusion block 231 returns to its initial position, and the staff presses the platinum sheet 21 so that the two sides of the platinum sheet 21 contact the side walls of the two first fixing sheets 241 respectively, so that the platinum sheet 21 is restricted by the first V-shaped sheet 242 again, so as to prevent the platinum sheet 21 from flipping outward and affecting the normal insertion of the platinum thermal resistor 15, so that the subsequent platinum thermal resistor 15 is more convenient to insert into the temperature measuring tank 14.

[0055] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
