Technical Field
[0001] The present disclosure relates to the technical field of carbon brush temperature measurement, and more particularly, to a carbon brush temperature measurement device and a generator carbon brush assembly. Background Art
[0002] The carbon brush is an important component of the generator. Its main function is to introduce direct current into the generator rotor, so that the generator rotor generates an exciting current, and then the generator rotor generates a magnetic field.
[0003] During the operation of the generator, due to the change of the generator load or the wear of the carbon brush, the temperature of the carbon brush is likely to rise. However, a high carbon brush temperature will affect the normal operation of the generator, and even cause fire and explosion. In order to avoid the above situation, in the related art, a large number of temperature measurement components are usually installed around the slip ring of the carbon brush to monitor the temperature of the carbon brush, resulting in a high cost. Summary of the Utility Model
[0004] The purpose of the present disclosure is to provide a carbon brush temperature measurement device and a generator carbon brush assembly to solve the technical problems existing in the related art.
[0005] According to the first aspect of the present disclosure, there is provided a carbon brush temperature measurement device, comprising:
[0006] A track, adapted to be arranged outside the carbon brush of the generator, and the track is adapted to surround the slip ring of the generator;
[0007] A temperature measurement module, for measuring the temperature of the carbon brush;
[0008] A moving member, the moving member is used to mount the temperature measurement module, and the temperature measurement module is movably arranged on the track through the moving member, so that the temperature measurement module can measure the temperatures of carbon brushes at different positions; and
[0009] A moving device, connected to the moving member, and the moving device is used to drive the moving member to reciprocate on the track.
[0010] Optionally, the temperature measurement module is rotatably arranged on the moving member;
[0011] Moreover, the included angle between the temperature measurement module and the upper surface of the moving member is set to be adjustable.
[0012] Optionally, the shape of the track is arc-shaped and is adapted to the shape of the outer side wall of the slip ring of the engine.
[0013] Optionally, the carbon brush temperature measurement device is adapted to be arranged in the slip ring housing of the slip ring of the generator.
[0014] Optionally, the carbon brush temperature measuring device further includes a bracket, and both ends of the track are connected to the bracket;
[0015] Wherein, the first end of the bracket is detachably connected to the slip ring holder of the generator, and the second end of the bracket is detachably connected to the slip ring housing of the generator.
[0016] Optionally, the carbon brush temperature measuring device further includes a screw. A first threaded hole is provided at the first end of the bracket. The screw is adapted to pass through the first threaded hole and be threadedly connected to a second threaded hole provided on the slip ring holder to fix the carbon brush temperature measuring device on the slip ring holder.
[0017] Optionally, a magnetic member is provided at the second end of the bracket. The magnetic member is adapted to adsorb on the inner wall of the slip ring housing to connect the bracket to the slip ring housing.
[0018] Optionally, the bracket includes a first support rod and a second support rod, and the first support rod and the second support rod are respectively arranged on both sides of the track;
[0019] The first end of the first support rod and the first end of the second support rod are both detachably connected to the slip ring holder of the generator, and the second end of the first support rod and the second end of the second support rod are both adapted to be detachably connected to the slip ring housing of the generator;
[0020] Wherein, the first support rod, the second support rod and the track are integrally formed.
[0021] Optionally, the temperature measuring module is configured as an infrared temperature measuring camera.
[0022] According to a second aspect of the present disclosure, there is provided a generator carbon brush assembly, including a carbon brush, a slip ring, a slip ring holder, a slip ring housing, and the carbon brush temperature measuring device as described above;
[0023] The track is adapted to be arranged outside the carbon brush of the generator, and the track is adapted to surround the slip ring of the generator;
[0024] The temperature measuring module is installed on the moving member, and the temperature measuring module is movably arranged on the track through the moving member so that the temperature measuring module can measure the temperatures of carbon brushes at different positions;
[0025] The moving device is connected to the moving member, and the moving device is used to drive the moving member to reciprocate on the track.
[0026] Through the above technical solution, since the slip rings of the generator are arranged around the track, when the temperature measurement module reciprocates along the track under the action of the moving part, the temperature measurement module can measure the temperature at different positions on the carbon brush. Compared with the technical solution in the related art where a large number of temperature measurement components are installed around the slip ring of the carbon brush to monitor the temperature of the carbon brush, the carbon brush temperature measurement device of the present application does not need to set multiple temperature measurement modules. Only one temperature measurement module can realize the monitoring of the temperatures at different positions of the entire carbon brush, which is beneficial to reducing the number of temperature measurement modules, thereby reducing the cost increase caused by using more temperature measurement modules, and thus is beneficial to saving the monitoring cost of the carbon brush temperature.
[0027] In addition, since the track is arranged outside the carbon brush of the generator, when the temperature measurement module reciprocates along the extending direction of the track under the action of the moving part, the temperature measurement module and / or the moving part will not interfere with the carbon brush of the generator. In other words, the carbon brush temperature measurement device will not affect the normal operation of the carbon brush, effectively avoiding the situation where the carbon brush temperature measurement device interferes with the carbon brush and the carbon brush cannot operate normally.

Specific Embodiment
[0034] The following will describe the specific implementation of the present disclosure in detail with reference to the drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure and does not limit the present disclosure.
[0035] In the present disclosure, it should be understood that the orientation terms such as "upper" and "lower" are defined based on the drawing direction of the drawings, and are only for the convenience of describing the present disclosure and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, as well as a specific orientation structure and operation. Therefore, it should not be construed as a limitation to the present disclosure. The terms "inner" and "outer" refer to the inside and outside of the corresponding structural contour. In addition, it should be noted that the terms such as "first" and "second" are used to distinguish one element from another, and do not have sequentiality and importance. Additionally, in the description with reference to the drawings, the same reference numerals in different drawings represent the same elements.
[0036] In the description of the present disclosure, it should also be noted that unless otherwise clearly specified and limited, the terms "arranged", "connected", "coupled", and "installed" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present disclosure can be understood according to specific circumstances.
[0037] As Figures 1 to 2 shown, according to a first aspect of the present disclosure, there is provided a carbon brush temperature measuring device 10, including a track 1, a temperature measuring module 2, a moving member 3, and a moving device. The track 1 is adapted to be arranged on the outside of the carbon brush 100 of the generator, and the track 1 is adapted to surround the slip ring of the generator. The temperature measuring module 2 is used to measure the temperature of the carbon brush 100. The moving member 3 is used to mount the temperature measuring module 2. The temperature measuring module 2 is movably arranged on the track 1 through the moving member 3, so that the temperature measuring module 2 can measure the temperatures of the carbon brush 100 at different positions. The moving device is connected to the moving member 3, and the moving device is used to drive the moving member 3 to reciprocate on the track 1.
[0038] Through the above technical solution, since the track 1 surrounds the slip ring of the generator, when the temperature measuring module 2 reciprocates along the track 1 under the action of the moving member 3, the temperature measuring module 2 can measure the temperatures of different positions on the carbon brush 100. Compared with the technical solution in the related art where a large number of temperature measuring components are installed around the slip ring of the carbon brush to monitor the temperature of the carbon brush, the carbon brush temperature measuring device 10 of the present application does not need to set multiple temperature measuring modules 2. Only one temperature measuring module 2 can realize the monitoring of the temperatures of different positions of the entire carbon brush 100. This is beneficial to reducing the number of temperature measuring modules 2, thereby reducing the cost increase caused by using more temperature measuring modules 2, and thus is beneficial to saving the monitoring cost of the temperature of the carbon brush 100.
[0039] In addition, since the track 1 is arranged outside the carbon brush 100 of the generator, even when the temperature measuring module 2 reciprocates along the extension direction of the track 1 under the action of the moving member 3, the temperature measuring module 2 and / or the moving member 3 will not interfere with the carbon brush 100 of the generator. In other words, the carbon brush temperature measuring device 10 will not affect the normal operation of the carbon brush 100, effectively avoiding the situation where the carbon brush temperature measuring device 10 interferes with the carbon brush 100 and the carbon brush 100 cannot operate normally.
[0040] In order to further improve the temperature measuring effect of the above carbon brush temperature measuring device 10 on the carbon brush 100, optionally, the temperature measuring module 2 is rotatably arranged on the moving member 3, and the included angle between the temperature measuring module 2 and the upper surface of the moving member 3 is set to be adjustable. In other words, the temperature measuring module 2 can rotate along the extension direction of the track 1 under the action of the moving member 3, and the temperature measuring module 2 can also rotate on the moving member 3. In this way, when the position of the temperature measuring module 2 on the track 1 changes, the temperature measuring module 2 can adjust its own rotation angle, and the temperature measuring module 2 can always be directly opposite to the carbon brush 100, so as to measure the temperature of the carbon brush 100, which is beneficial to improving the temperature measuring accuracy of the temperature measuring module 2 for the carbon brush 100.
[0041] In addition, since the included angle between the temperature measuring module 2 and the upper surface of the moving member 3 is set to be adjustable, in other words, the temperature measuring module 2 can adjust the pitching angle. By adjusting the pitching angle of the temperature measuring module 2 on the moving member 3, the temperature measuring module 2 can be respectively oriented towards a plurality of carbon brushes 100 arranged at intervals in the radial direction of the generator shaft. With such a design, the above temperature measuring module 2 can not only measure the temperatures of different positions on one carbon brush 100 through the moving member 3 and the track 1, but also measure the temperatures of a plurality of carbon brushes 100 arranged at intervals in the radial direction of the generator shaft by adjusting its pitching angle, and the practicability of the carbon brush temperature measuring device 10 is relatively high.
[0042] It should be noted that the present disclosure does not limit the shape of the track 1, as long as the track 1 surrounds the slip ring of the generator and is suitable for installing the moving member 3. As an implementation manner of the present disclosure, as Figure 1 shown, the shape of the above track 1 is arc-shaped and is suitable for adapting to the shape of the outer wall of the slip ring of the engine. In other words, the shape of the track 1 is the same as the shape of the outer wall of the slip ring of the generator. In this way, even when the temperature measuring module 2 is located at different positions on the track 1, the distance between the temperature measuring module 2 and the slip ring is the same. With such a design, it is possible to avoid the situation where the temperature measured by the temperature measuring module 2 has an error due to the change in the distance between the temperature measuring module 2 and the slip ring, and the temperature measuring accuracy of the carbon brush temperature measuring device 10 is improved.
[0043] The present disclosure does not limit the specific installation position of the carbon brush temperature measuring device 10 on the generator, as long as the carbon brush temperature measuring device 10 can measure the temperature of the carbon brush 100 of the generator. As an embodiment of the present disclosure, as Figure 1 shown, the above-mentioned carbon brush temperature measuring device 10 is adapted to be arranged in the slip ring housing 200 of the slip ring of the generator. On the one hand, the carbon brush temperature measuring device 10 arranged in the slip ring housing 200 of the generator is not blocked by the slip ring housing 200, and the temperature measuring module 2 can measure the actual temperature of the carbon brush 100, and the error of the temperature measuring module 2 is relatively low. On the other hand, the slip ring housing 200 can also play a role in protecting the carbon brush temperature measuring device 10, effectively avoiding the situation that the carbon brush temperature measuring device 10 is easily damaged when exposed outside, and improving the service life of the carbon brush temperature measuring device 10.
[0044] In order to facilitate the installation of the carbon brush temperature measuring device 10 in the slip ring housing 200 of the slip ring of the generator, optionally, as Figure 1 shown, the carbon brush temperature measuring device 10 further includes a bracket 5. Both ends of the track 1 are connected to the bracket 5. Among them, the first end of the bracket 5 is detachably connected to the slip ring frame 300 of the generator, and the second end of the bracket 5 is detachably connected to the slip ring housing 200 of the generator. In other words, the track 1 is connected to the slip ring frame 300 of the generator and the slip ring housing 200 of the generator through the bracket 5 at the same time, and the carbon brush temperature measuring device 10 is fixed reliably on the generator, effectively avoiding the situation that the carbon brush temperature measuring device 10 shakes and causes the carbon brush temperature measuring device 10 to be unable to measure the temperature of the carbon brush 100 normally.
[0045] The present disclosure does not limit the specific connection method between the above-mentioned bracket 5 and the slip ring frame 300 of the generator. As an embodiment of the present disclosure, as Figure 1 and Figure 2 shown, the carbon brush 100 temperature measuring device further includes a screw 6. The first end of the bracket 5 is provided with a first threaded hole 51, and the screw 6 is adapted to pass through the first threaded hole 51 and be threadedly connected to the second threaded hole provided on the slip ring frame 300 to fix the carbon brush temperature measuring device 10 on the slip ring frame 300.
[0046] Similarly, the present disclosure does not limit the specific connection relationship between the above-mentioned bracket 5 and the slip ring housing 200. As an embodiment of the present disclosure, as Figure 1As shown, a magnetic member 52 is provided at the second end of the bracket 5. The magnetic member 52 is adapted to be adsorbed on the inner wall of the slip ring housing 200 to connect the bracket 5 to the slip ring housing 200. Since the second end of the bracket 5 is connected to the inner wall of the slip ring housing 200 through the magnetic member 52, the connection between the bracket 5 and the slip ring housing 200 is relatively convenient. Only need to connect the first end of the bracket 5 to the slip ring holder 300 of the generator, and then install the slip ring housing 200 on the slip ring holder 300, the second end of the bracket 5 can be adsorbed on the inner wall of the slip ring housing 200. The connection between the bracket 5 and the slip ring housing 200 is relatively convenient. Moreover, the fixing of the bracket 5 can be achieved without separately modifying the slip ring housing 200 (for example, opening holes in the slip ring housing 200), and the versatility of the bracket 5 is relatively high.
[0047] It should be noted that the specific structure of the bracket 5 is not limited in the present disclosure. As an embodiment of the present disclosure, as Figure 1 shown, the bracket 5 includes a first support rod 53 and a second support rod 54. The first support rod 53 and the second support rod 54 are respectively arranged on both sides of the track 1. The first ends of the first support rod 53 and the second support rod 54 are detachably connected to the slip ring holder 300 of the generator, and the second ends of the first support rod 53 and the second support rod 54 are both adapted to be detachably connected to the slip ring housing 200 of the generator. Among them, the first support rod 53, the second support rod 54 and the track 1 are integrally formed. The first support rod 53 and the second support rod 54 can jointly support the track 1, and the track 1 is not easy to shake.
[0048] In addition, since the first support rod 53 and the second support rod 54 are integrally formed, in the installation process of the above-mentioned carbon brush temperature measuring device 10, there is no need to separately assemble the bracket 5 and the track 1, which is also beneficial to improving the disassembly and assembly efficiency of the carbon brush temperature measuring device 10.
[0049] The specific type of the temperature measuring module 2 is not limited in the present disclosure. As an embodiment of the present disclosure, the above-mentioned temperature measuring module 2 can be configured as an infrared temperature measuring camera. The infrared temperature measuring camera can not only measure the temperature of the carbon brush 100, but also transmit the real-time picture of the carbon brush 100 to the operator, so as to facilitate the operator to monitor the operating state of the carbon brush 100.
[0050] The specific temperature measuring method of the above-mentioned carbon brush temperature measuring device 10 is not limited in the present disclosure. Optionally, the moving member 3 can be started regularly under the control of the remote server, so that the temperature measuring module 2 can slowly move along the extending direction of the track 1, thereby measuring the temperature of different positions of the carbon brush 100 and transmitting the measured results back to the server. The operator can make different decisions according to the measurement results of the carbon brush temperature measuring device 10.
[0051] According to a second aspect of the present disclosure, a generator carbon brush 100 assembly is provided, including a carbon brush 100, a slip ring, a slip ring holder 300, a slip ring housing 200, and the carbon brush temperature measuring device 10 as described above. A track 1 is adapted to be disposed outside the carbon brush 100 of the generator, and the track 1 is adapted to surround the slip ring of the generator. A temperature measuring module 2 is installed on a moving member 3, and the temperature measuring module 2 is movably disposed on the track 1 through the moving member 3 so that the temperature measuring module 2 can measure the temperatures of the carbon brush 100 at different positions. A moving device is connected to the moving member 3, and the moving device is used to drive the moving member 3 to reciprocate on the track 1.
[0052] This generator carbon brush 100 assembly has all the beneficial effects of the above carbon brush temperature measuring device 10, which will not be elaborated here.

However, the present disclosure is not limited to the specific details in the above embodiments. Within the scope of the technical concept of the present disclosure, various simple modifications can be made to the technical solutions of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.
[0054] In addition, it should be noted that, in the above specific embodiments, the various specific technical features described can be combined in any suitable manner without conflict. To avoid unnecessary repetition, the present disclosure will not separately describe various possible combination methods.
[0055] Furthermore, any combination can be made between various different embodiments of the present disclosure as long as it does not violate the idea of the present disclosure, and it should also be regarded as the content disclosed by the present disclosure.
