Description

Technical Field

[0001] This invention relates to the field of power production technology, and in particular to an automatic temperature measuring and cooling device for carbon brushes. Background Technology

[0002] Carbon brushes, also known as electric brushes, are sliding contact components used to transmit excitation current between the stationary and rotating parts of electric motors, generators, or other rotating machinery. The main materials for carbon brushes include graphite, resin-impregnated graphite, and metallic (containing copper and silver) graphite. They are generally made of pure carbon with a solidifying agent and are widely used in many electrical devices. During operation, the motor's slip rings continuously contact the carbon brushes, causing the brush temperature to rise as the slip rings rotate. To prevent overheating and subsequent malfunctions, the carbon brush temperature needs to be frequently measured to ensure proper functioning. This temperature measurement requires the use of a temperature measuring device.

[0003] However, existing carbon brush temperature measuring devices have certain shortcomings:

[0004] First, existing carbon brush temperature measuring devices usually require staff to hold the device to measure the temperature. Since the slip ring is usually equipped with a protective cover, it is inconvenient to measure the temperature manually. After the carbon brush has been working for a long time, its temperature needs to be monitored in real time. However, relying on manual monitoring has certain limitations and cannot provide timely feedback on changes in carbon brush temperature.

[0005] Secondly, existing carbon brush temperature measuring devices only have a temperature measuring function. If the carbon brush temperature is too high and reaches the critical value, it needs to report the temperature to the staff, who then cool the carbon brush. This process takes a lot of time, and the carbon brush may be damaged if the temperature is not reduced in time, which may lead to motor failure and inability to work. Summary of the Invention

[0006] The purpose of this invention is to provide an automatic temperature measurement and cooling device for carbon brushes to solve the problems mentioned in the background art.

Both the air inlet pipe and the air outlet pipe are connected to the spiral tube.

[0009] Preferably, the end of the air outlet pipe is connected to a conveying pipe, and the end of the conveying pipe is provided with an air outlet cover. The air outlet cover is funnel-shaped, and the outer wall of the air outlet cover is provided with a magnetic ring, which is adapted to the air outlet cover.

[0010] Preferably, a connecting ring is rotatably installed at one end of the delivery pipe near the outlet pipe, and the outer wall of the outlet pipe is provided with equally spaced external threads, and the connecting ring and the outlet pipe are rotatably connected by the threads.

[0011] Preferably, the outer wall of the conveying pipe is provided with a telescopic flexible hose, which is adapted to the conveying pipe. A fixing frame is installed on the outer wall of the conveying pipe, which is adapted to the extension groove. An anti-slip pad adapted to the fixing frame is provided on the inner wall of the fixing frame.

[0012] Preferably, the outer wall of the extension rod has equally spaced fixing holes, and a fixing pin is inserted into the top of the outer wall of the extension groove near one end of the extension rod. The fixing pin is adapted to the fixing holes, and the length of the fixing pin is greater than the thickness of the extension rod.

[0013] Preferably, the control component includes a threaded hole formed at one corner of the outer wall of the top of the housing, the threaded hole being adapted to the cooling cavity, the depth of the threaded hole being less than the height of the housing, a threaded rod being rotatably installed on the inner wall of the threaded hole via a thread, a support groove being welded to the top of the threaded rod, and a connecting cylinder being provided at one end of the bottom outer wall of the extension groove, the connecting cylinder being adapted to the support groove, and the connecting cylinder being rotatably connected to the support groove.

[0014] Preferably, the outer wall of the top of the box is provided with a placement groove, the placement groove is provided with a cover plate that is adapted to it, the inner wall of the placement groove is provided with a protective pad, the protective pad is adapted to the cover plate, and the placement groove is adapted to the extension groove, extension rod, connecting rod, infrared thermometer, conveying pipe and air vent.

[0015] Preferably, the outer wall of the housing is provided with an observation window, which is located below the display and is adapted to the cooling cavity.

[0016] Preferably, the outer wall of the housing near the air intake pipe is provided with a filling groove, the filling groove leads into the cooling chamber, the filling groove is provided with a matching sealing cover, and the bottom of the outer wall of the housing near the filling groove is provided with a drain pipe, the outer wall of the drain pipe is provided with a matching control valve.

[0017] In summary, the technical effects and advantages of this invention are as follows:

[0018] In this invention, during operation, the device is moved to the motor position. First, the control component is connected to the housing, and then the temperature measuring component is connected to the control component. When measuring the temperature of the carbon brush, the height of the temperature measuring component is adjusted according to the height of the carbon brush. Then, the extension rod is slid along the inner wall of the extension groove, allowing the connecting rod and the infrared thermometer to enter the motor through the gap in the protective cover. This enables the infrared thermometer to be aligned with the carbon brush and monitor the carbon brush temperature in real time. The display shows the carbon brush temperature monitored by the infrared thermometer in real time, facilitating understanding of carbonization temperature changes and timely implementation of cooling measures. Compared to traditional carbon brush temperature measuring devices, manual measurement is not required. The carbonization temperature can be measured in real time during carbon brush operation, providing timely feedback on carbon brush temperature changes, facilitating temperature adjustment and preventing damage caused by excessive carbon brush temperature.

[0019] In this invention, after the temperature measuring component is aligned with the carbon brush, the delivery pipe is connected to the exhaust pipe. Then, the delivery pipe is fixed to the extension groove by the fixing bracket, which facilitates the connection between the delivery pipe and the motor protective cover. The exhaust cover is then attached to the outer wall of the iron protective cover by the magnetic ring on the outer wall of the exhaust cover, thereby fixing the delivery pipe. The telescopic flexible hose in the middle of the delivery pipe allows for adjustment of the height and length of the exhaust cover as needed, so that it can be aligned with the position of the carbon brush, thereby spraying out cold air to cool the carbon brush when it overheats.

[0020] In this invention, during carbon brush cooling, the intake pipe draws outside air into the spiral tube. Since the spiral tube is immersed in the coolant in the cooling chamber, the outside air exchanges heat with the coolant through the tube wall as it flows through the spiral tube, thereby achieving air cooling. Furthermore, the spiral structure of the spiral tube helps to prolong the residence time of the air in the cooling chamber, facilitating thorough air cooling. The cooled air is then fed into the exhaust hood through the delivery pipe and sprayed onto the carbon brush. The airflow around the carbon brush allows for rapid absorption of heat from the surrounding air, thus achieving carbon brush cooling. Compared to traditional temperature measuring devices, this invention provides cooling capabilities while measuring temperature. When the carbon brush temperature exceeds the critical point, it rapidly cools the brush, preventing carbon brush failure.

[0021] In this invention, during the installation of the temperature measuring component, the support groove drives the threaded rod to rotate along the inner wall of the threaded hole, causing the support groove to gradually rise. This allows the height of the temperature measuring component to be adjusted as needed, facilitating the temperature measuring component's work on the carbon brush. Since the control component, temperature measuring component, and delivery pipe are all detachable, the placement groove 22 facilitates the storage of the disassembled components. When the device is not in use, all relevant components can be disassembled and stored. Compared to traditional temperature measuring devices, storing relevant components in the placement groove during device transfer or transportation effectively prevents damage from collisions and other factors. Furthermore, the device occupies less space after storage, making it easier to transport. Attached Figure Description

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] refer to Figure 1-6 The carbon brush automatic temperature measurement and cooling device shown includes a housing 1. Universal wheels are bolted to all four sides of the bottom outer wall of the housing 1, and the universal wheels are equipped with locking components. A control component is located at one end of the top outer wall of the housing 1, and the control component is connected to a temperature measuring component. The control component and the temperature measuring component are compatible. A cooling component is located inside the housing 1. The temperature measuring component includes an extension groove 2, an extension rod 3 slidably mounted on the inner wall of the extension groove 2, and a connecting rod 4 threaded to the end of the extension rod 3. An infrared thermometer 5 is located at the end of the connecting rod 4. A power supply 6 is located on the outer wall of the connecting rod 4, and the power supply 6 is connected to the infrared thermometer 5 via a wire. A display 7 is located on the top of the outer wall of the housing 1. The infrared thermometer 5 is connected to a controller via a wireless network, and the controller is connected to the display 7 via a wireless network. An observation window 25 is located on the outer wall of the housing 1, below the display 7, and is compatible with a cooling chamber 8.

[0031] With the above structure: During operation, the device is moved to the motor position. First, the control component is connected to the housing 1, and then the temperature measuring component is connected to the control component. When measuring the temperature of the carbon brush, the height of the temperature measuring component is adjusted according to the height of the carbon brush. Then, the extension rod 3 is slid along the inner wall of the extension groove 2, so that the connecting rod 4 and the infrared thermometer 5 enter the motor through the gap of the protective cover. This allows the infrared thermometer 5 to be aligned with the carbon brush and monitor the carbon brush temperature in real time. The display 7 shows the carbon brush temperature monitored by the infrared thermometer 5 in real time, which is convenient for understanding the carbonization temperature change and taking timely cooling measures. Compared with traditional carbon brush temperature measuring devices, no manual measurement is required. The carbonization temperature can be measured in real time during the carbon brush operation, and the carbon brush temperature change can be fed back in time, which is convenient for adjusting the carbon brush temperature and preventing the carbon brush from being damaged due to excessive temperature.

[0032] like Figure 6 As shown, the cooling assembly includes a cooling chamber 8 located inside the housing 1, containing cooling water. A spiral tube 9 is installed on the inner wall of the cooling chamber 8. An air inlet pipe 10 is located at the bottom of one side of the housing 1, and an air pump 11 adapted to it is installed on the outer wall of the air inlet pipe 10. An air outlet pipe 12 is located on the outer wall of the housing 1 away from the air inlet pipe 10. Both the air inlet pipe 10 and the air outlet pipe 12 are connected to the spiral tube 9. A conveying pipe 13 is connected to the end of the air outlet pipe 12, and an air outlet hood 14 is installed at the end of the conveying pipe 13. The air outlet hood 14 is funnel-shaped, and a magnetic ring 15 is installed on the outer wall of the air outlet hood 14. 15 is adapted to the vent hood 14. A connecting ring 16 is rotatably installed on one end of the conveying pipe 13 near the vent pipe 12. The outer wall of the vent pipe 12 is provided with equally spaced external threads. The connecting ring 16 and the vent pipe 12 are rotatably connected by the threads. A telescopic hose is provided on the outer wall of the conveying pipe 13, and the telescopic hose is adapted to the conveying pipe 13. A fixing bracket 17 is installed on the outer wall of the conveying pipe 13, and the fixing bracket 17 is adapted to the extension groove 2. The inner wall of the fixing bracket 17 is provided with a matching anti-slip pad. After the temperature measuring component is aligned with the carbon brush, the conveying pipe 13 is connected to the vent pipe 12, and then the conveying pipe is connected to the vent pipe 12 through the fixing bracket 17. The pipe 13 is fixed to the extension groove 2, facilitating the connection between the conveying pipe 13 and the motor protective cover. The vent 14 is then attached to the outer wall of the iron protective cover via a magnetic ring 15 on its outer wall, thus fixing the conveying pipe 13. The telescopic flexible hose in the middle section of the conveying pipe 13 allows for adjustment of the height and length of the vent 14 as needed, ensuring it is aligned with the carbon brush location. This allows for the spraying of cold air to cool the carbon brush when it overheats. During carbon brush cooling, the intake pipe 10 draws outside air into the spiral tube 9. Since the spiral tube 9 is immersed in the coolant in the cooling chamber 8, outside air is drawn into the spiral tube 9. When the air flows through the pipe wall, it exchanges heat with the coolant, thereby cooling the air. The spiral structure of the spiral tube 9 helps to prolong the residence time of the air in the cooling chamber 8, facilitating sufficient cooling. The cooled air is then fed into the exhaust hood 14 through the delivery pipe 13 and sprayed out. The cooled air sprays onto the carbon brush, and the surrounding airflow quickly absorbs the heat from the surrounding air, thus cooling the carbon brush. Compared with traditional temperature measuring devices, this device has cooling capabilities while measuring temperature. When the carbon brush temperature exceeds the critical point, it quickly cools the carbon brush to prevent carbon brush failure.

[0033] like Figure 1 As shown, the outer wall of the extension rod 3 has equally spaced fixing holes 18. A fixing pin 19 is inserted into the top of the outer wall of the extension groove 2 near the end of the extension rod 3. The fixing pin 19 is adapted to the fixing holes 18. The length of the fixing pin 19 is greater than the thickness of the extension rod 3. The fixing pin 19 and the fixing holes 18 cooperate to lock the extension rod 3 and the extension groove 2. The length of the extension rod 3 sliding out of the extension groove 2 can be adjusted as needed.

[0034] like Figure 1 As shown, the control component includes a threaded hole at one corner of the top outer wall of the housing 1. The threaded hole is adapted to the cooling cavity 8. The depth of the threaded hole is less than the height of the housing 1. A threaded rod 20 is installed on the inner wall of the threaded hole by thread rotation. A support groove 21 is welded to the top of the threaded rod 20. A connecting cylinder is provided at one end of the bottom outer wall of the extension groove 2. The connecting cylinder is adapted to the support groove 21 and is rotatably connected to the support groove 21. When the temperature measuring component is installed, the support groove 21 is rotated first to drive the threaded rod 20 to rotate along the inner wall of the threaded hole, so that the support groove 21 gradually rises, so that the height of the temperature measuring component can be changed as needed, which facilitates the temperature measuring component to measure the temperature of the carbon brush.

[0035] like Figure 4 As shown, a placement slot 22 is provided on the top outer wall of the housing 1. The placement slot 22 is equipped with a cover plate 23 that is compatible with it. A protective pad 24 is provided on the inner wall of the placement slot 22. The protective pad 24 is compatible with the cover plate 23. The placement slot 22 is compatible with the extension slot 2, extension rod 3, connecting rod 4, infrared thermometer 5, conveying pipe 13, and air vent 14. Since the control components, temperature measuring components, and conveying pipe 13 are all detachable, the placement slot 22 facilitates the storage of the disassembled components. When the device is not in use, all relevant components can be disassembled and stored. Compared with traditional temperature measuring devices, the placement slot 22 can effectively prevent damage to the relevant components from collisions and other factors during the transfer or transportation of the device. Moreover, the device occupies less space after storage, which is convenient for the transportation of the device.

[0036] like Figure 1 As shown, a filling groove 26 is provided on the outer wall of the housing 1 near the air intake pipe 10. The filling groove 26 leads into the cooling chamber 8. The filling groove 26 is provided with a matching sealing cover. A drain pipe 27 is provided at the bottom of the outer wall of the housing 1 near the filling groove 26. A control valve is provided on the outer wall of the drain pipe 27. The filling groove 26 facilitates the addition of ice or other refrigerant to the cooling chamber 8. The drain pipe 27 can drain and replace the cooling water after long-term use.

[0037] Working principle of this invention:

[0038] During operation, the device is moved to the motor position. First, the control component is connected to the housing 1, and then the temperature measuring component is connected to the control component. When measuring the temperature of the carbon brush, the height of the temperature measuring component is adjusted according to the height of the carbon brush. Then, the extension rod 3 is slid along the inner wall of the extension groove 2 so that the connecting rod 4 and the infrared thermometer 5 enter the motor through the gap of the protective cover, so that the infrared thermometer 5 can be aligned with the carbon brush and monitor the carbon brush temperature in real time. The display 7 displays the carbon brush temperature monitored by the infrared thermometer 5 in real time, which is convenient for understanding the carbonization temperature change and taking timely cooling measures. Compared with traditional carbon brush temperature measuring devices, no manual measurement is required. The carbonization temperature can be measured in real time during the carbon brush operation, and the carbon brush temperature change can be fed back in time, which is convenient for adjusting the carbon brush temperature and preventing the carbon brush from being damaged due to excessive temperature.

[0039] After the temperature measuring component is aligned with the carbon brush, the delivery pipe 13 is connected to the air outlet pipe 12. Then, the delivery pipe 13 is fixed to the extension groove 2 by the fixing bracket 17, so that the delivery pipe 13 can be connected to the motor protective cover. Then, the air outlet cover 14 is attracted to the outer wall of the iron protective cover by the magnetic ring 15 on the outer wall of the air outlet cover 14, thereby fixing the delivery pipe 13. The telescopic hose in the middle section of the delivery pipe 13 can be adjusted as needed to adjust the height and length of the air outlet cover 14 so that it can be aligned with the carbon brush position, so that cold air is sprayed out to cool the carbon brush when it is overheated.

[0040] When the carbon brush is cooled, the air inlet pipe 10 draws outside air into the spiral tube 9. Since the spiral tube 9 is immersed in the coolant in the cooling chamber 8, the outside air exchanges heat with the coolant through the tube wall when it flows in the spiral tube 9, thereby achieving air cooling. The spiral structure of the spiral tube 9 helps to prolong the residence time of the air in the cooling chamber 8, which facilitates the air to be fully cooled. The cooled air is fed into the air outlet hood 14 through the delivery pipe 13 and sprayed out. The cooled air sprays onto the carbon brush. With the addition of the air flow around the carbon brush, it can quickly absorb the heat of the air around the carbon brush and thus achieve carbon brush cooling. Compared with traditional temperature measuring devices, it has the ability to cool down while measuring temperature. When the carbon brush temperature exceeds the critical point, it can quickly cool down the carbon brush to prevent carbon brush failure.

[0041] When installing the temperature measuring component, first rotate the support groove 21 to drive the threaded rod 20 to rotate along the inner wall of the threaded hole, so that the support groove 21 gradually rises, allowing it to change the height of the temperature measuring component as needed, which facilitates the temperature measuring component to measure the temperature of the carbon brush. Since the control component, temperature measuring component, and delivery pipe 13 are all detachable, the placement groove 22 facilitates the storage of the disassembled parts. When the device is not in use, all relevant parts can be disassembled and stored. Compared with traditional temperature measuring devices, during the transfer or transportation of the device, storing relevant parts through the placement groove 22 can effectively prevent damage from factors such as collisions, and the device occupies less space after storage, which is convenient for the transportation of the device.

[0042] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
