Description

Technical Field

[0001] This utility model relates to the field of thermocouple repair technology, specifically a thermocouple repair device. Background Technology

[0002] Thermocouples are commonly used temperature measuring elements in temperature measuring instruments. They directly measure temperature and convert the temperature signal into a thermoelectric potential signal, which is then converted into the temperature of the measured medium by an electrical instrument (secondary instrument).

[0003] Patent CN114923595B discloses a method for repairing armored thermocouples used for temperature measurement in the cylinder block of a thermal power unit turbine, relating to the field of turbine maintenance technology. The method includes the following steps: cleaning the exposed thermocouple wires; polishing the surface of the thermocouple wires with 300 to 500 grit sandpaper; dispersing the polished thermocouple wires; applying a coating to the thermocouple wires; wrapping and fixing the coated thermocouple wires with glass ribbon; and covering the repair area with a thin aluminum plate until the thermocouple wires are working normally.

[0004] While existing technologies enable rapid online restoration of thermocouple insulation and resistance after bursting and allow damaged armored thermocouples to be used normally again, they cannot easily control the mixture of high-temperature insulating and anti-corrosion coating and curing agent during use, which can easily lead to leakage and waste of the mixture.

[0005] To address the aforementioned problems, this application proposes a thermocouple repair device. Utility Model Content

[0006] To address the problem that existing technologies often result in leakage and waste due to the inability to easily control the mixture of high-temperature resistant insulating and anti-corrosion coating and curing agent, the purpose of this invention is to provide a thermocouple repair device.

[0007] To solve the above technical problems, the present invention adopts the following technical solution: a thermocouple repair device, including a barrel, a barrel cap detachably provided at the top of the barrel, and a rotating frame that can slide against the inner wall of the barrel cap. The outer wall of the barrel cap is provided with grooves for use, and the grooves are arranged in an array. A rotating rod is rotatably inserted into the bottom of the barrel, and a coating roller for use is fixedly sleeved at the lower end of the rotating rod. A material hole for use with the coating roller is opened through the bottom of the barrel, and the material holes are arranged in an array. A material control mechanism for use with the coating roller is provided at the lower end of the barrel, and a mixing mechanism for use with the rotating rod is provided in the inner cavity of the barrel.

[0008] The material control mechanism includes a rotating drum, which is rotatably sleeved on the bottom end of a material cylinder. The bottom end of the rotating drum is in contact with the coating roller. A limiting protrusion is integrally formed on the lower outer wall of the material cylinder, and the rotating drum is rotatably sleeved on the limiting protrusion. A limiting ring groove is opened at the upper end of the inner cavity of the rotating drum, and the limiting protrusion is slidably inserted into the limiting ring groove. Both the bottom of the inner cavity of the rotating drum and the bottom end of the material cylinder are damping structures. A push plate for use is fixedly installed on the outer wall of the rotating drum, and the push plates are arranged in an array. An array of arc-shaped grooves is opened through the lower end of the rotating drum, and the arc-shaped grooves can communicate with the material hole. An inner ring groove is opened at the lower end of the inner cavity of the rotating drum, and symmetrically arranged moving blocks are fixedly inserted into the inner side of the inner ring groove. An arc-shaped spring is fixedly installed on one side of the moving block, and the arc-shaped spring is movably inserted into the inner ring groove. A fixed block is fixedly connected to the end of the arc-shaped spring, and the fixed block is slidably inserted into the inner ring groove and fixedly connected to the outer wall of the material cylinder.

[0009] Preferably, the mixing mechanism includes a rotating frame, which is fixedly sleeved on the rotating rod, and the outer wall of the rotating frame slides against the inner wall of the material cylinder. Symmetrically distributed rotating plates are fixedly installed on the inner side of the rotating frame. Insertion holes are opened through the top and bottom ends of the rotating frame, and the rotating rod is fixedly inserted into the insertion holes.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. Through the design and use of the material control mechanism, the push plate can be easily rotated, which in turn drives the rotating drum to rotate, which in turn drives the arc groove and the moving block to rotate and squeeze the arc spring. This allows the arc groove to connect with the material hole. When the coating operation is completed and the push plate is released, the arc spring can easily push the moving block to reverse and reset, which in turn drives the rotating drum to reverse and reset, and the arc groove can reverse and reset and reposition itself with the material hole. This achieves convenient material control of the mixture of high-temperature resistant insulating and anti-corrosion coating and curing agent, avoiding leakage and waste of the mixture.

[0012] 2. The mixing mechanism can drive the rotating rod to rotate during the coating roller's rolling and brushing process, thereby driving the rotating frame and rotating plate to rotate synchronously. This can fully agitate the mixture of high-temperature resistant, insulating, and anti-corrosion coating and curing agent in the barrel, ensuring the uniformity of the mixture and effectively scraping off the material adhering to the inner wall of the barrel, thus preventing the material from sticking to the inner wall of the barrel.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example: Figures 1-5As shown, this utility model provides a thermocouple repair device, including a material cylinder 1. The top of the material cylinder 1 is detachably provided with a matching cylinder cover 6, and the rotating frame 51 can slide and fit against the inner wall of the cylinder cover 6. The setting of the cylinder cover 6 facilitates the introduction of the mixture of high temperature resistant insulating and anti-corrosion coating and curing agent into the material cylinder 1. The outer wall of the cylinder cover 6 is provided with matching grooves 61, and the grooves 61 are arranged in an array. The setting of the grooves 61 can increase friction and facilitate operation. The bottom end of the material cylinder 1 is rotatably inserted with a rotating rod 2, and the lower end of the rotating rod 2 is fixedly sleeved with a matching coating roller 3. The bottom end of the material cylinder 1 is provided with a material hole 11 that matches the coating roller 3, and the material holes 11 are arranged in an array. The lower end of the material cylinder 1 is provided with a material control mechanism 4 that matches the coating roller 3, and the inner cavity of the material cylinder 1 is provided with a mixing mechanism 5 that matches the rotating rod 2.

[0022] The material control mechanism 4 includes a rotating drum 41, which is rotatably sleeved on the bottom end of the material cylinder 1. The bottom end of the rotating drum 41 is in movable contact with the coating roller 3. A limiting protrusion ring 48 is integrally formed on the lower outer wall of the material cylinder 1, and the rotating drum 41 is rotatably sleeved on the limiting protrusion ring 48. A limiting ring groove 49 is formed at the upper end of the inner cavity of the rotating drum 41, and the limiting protrusion ring 48 is slidably inserted into the limiting ring groove 49. The cooperation between the limiting protrusion ring 48 and the limiting ring groove 49 ensures the stable rotation of the rotating drum 41. The bottom of the inner cavity of the rotating drum 41 and the bottom end of the material cylinder 1 are both damping structures. The outer wall of the rotating drum 41 is fixedly installed with... There are push plates 42 used in conjunction, and the push plates 42 are arranged in an array. The lower end of the rotating drum 41 is provided with an array of arc-shaped grooves 43, and the arc-shaped grooves 43 can communicate with the material hole 11. The lower end of the inner cavity of the rotating drum 41 is provided with an inner ring groove 44, and symmetrically arranged moving blocks 45 are fixedly inserted into the inner side of the inner ring groove 44. An arc-shaped spring 46 is fixedly installed on one side of the moving block 45, and the arc-shaped spring 46 is movably inserted into the inner ring groove 44. The end of the arc-shaped spring 46 is fixedly connected to a fixed block 47, which is slidably inserted into the inner ring groove 44 and fixedly connected to the outer wall of the material cylinder 1.

[0023] By adopting the above technical solution, when in use, the material cylinder 1 is held and the corresponding push plate 42 is pushed to rotate, which drives the rotating cylinder 41 to rotate, thereby driving the arc groove 43 and the moving block 45 to rotate and squeeze the arc spring 46. Then the arc groove 43 will connect with the material hole 11. Then the high temperature resistant insulating and anti-corrosion coating and curing agent mixture in the material cylinder 1 will be guided to the coating roller 3 through the corresponding material hole 11 and the arc groove 43. Then the bottom end of the coating roller 3 is attached to the part of the thermocouple wire to be repaired and the coating roller 3 is pushed to roll and coat the mixture. After the coating operation is completed, the push plate 42 is released. At this time, the arc spring 46 will push the moving block 45 to reverse and reset, thereby driving the rotating cylinder 41 to reverse and reset, and thus enabling the arc groove 43 to reverse and reset and be misaligned with the material hole 11 again.

[0024] The mixing mechanism 5 includes a rotating frame 51, which is fixedly sleeved on the rotating rod 2. The outer wall of the rotating frame 51 slides against the inner wall of the material cylinder 1. Symmetrically distributed rotating plates 52 are fixedly installed on the inner side of the rotating frame 51. Insertion holes 53 are opened through the top and bottom ends of the rotating frame 51, and the rotating rod 2 is fixedly inserted into the insertion holes 53. The setting of the insertion holes 53 provides a guarantee for the stable insertion of the rotating rod 2 and the rotating frame 51.

[0025] By adopting the above technical solution, during use, the rotating rod 2 will be driven to rotate during the rolling and brushing of the coating roller 3, thereby driving the rotating frame 51 and the rotating plate 52 to rotate synchronously, which can fully agitate the mixture of high temperature resistant insulating and anti-corrosion coating and curing agent in the material cylinder 1, and effectively scrape off the material adhering to the inner wall of the material cylinder 1.

[0026] Working principle: When in use, hold the material cylinder 1 and push the corresponding push plate 42 to rotate, which will drive the rotating cylinder 41 to rotate, which in turn will drive the arc groove 43 and the moving block 45 to rotate and squeeze the arc spring 46. Then the arc groove 43 will connect with the material hole 11. Then the high temperature resistant insulating and anti-corrosion coating and curing agent mixture in the material cylinder 1 will be guided to the coating roller 3 through the corresponding material hole 11 and the arc groove 43. Then the bottom end of the coating roller 3 is attached to the part of the thermocouple wire to be repaired and the coating roller 3 is pushed to roll and coat the mixture. After the coating operation is completed, release the push plate 42. At this time, the arc spring 46 will push the moving block 45 to reverse and reset, which will drive the rotating cylinder 41 to reverse and reset, and then the arc groove 43 will reverse and reset and be misaligned with the material hole 11 again.

[0027] In addition, during the coating process, the roller 3 will rotate the rotating rod 2, which will drive the rotating frame 51 and the rotating plate 52 to rotate synchronously. This will fully agitate the mixture of high-temperature resistant insulating and anti-corrosion coating and curing agent in the barrel 1, further ensuring the uniformity of the mixture and effectively scraping off the material adhering to the inner wall of the barrel 1, thus avoiding the phenomenon of material adhering to the inner wall of the barrel 1.

[0028] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
