Technical Field

[0001] The utility model relates to the technical field of bearing temperature detection, in particular to a device for detecting the temperature of a bearing of a mine water pump. Background Technique

[0002] During the long-term operation of a mine water pump, the bearing will generate high temperature.

It is very easy for the detection data to be inaccurate due to the failure of a certain internal part, which in turn affects the judgment of the actual temperature of the bearing by the staff. Therefore, a device for detecting the temperature of a bearing of a mine water pump is proposed. Summary of the Utility Model

[0022] Embodiment

[0023] As Figure 1 、 Figure 2 and Figure 3 shown, this embodiment is used for a mine water pump bearing temperature detection device, which includes a base 1. An installation mechanism is provided at the bottom of the base 1. By setting the installation mechanism, the device can be stably installed on the bearing seat, so as to detect the temperature of the bearing. A connecting block 10 is connected to the upper surface of the base 1. A copper tube 11 is inserted into the connecting block 10, and a threaded structure is provided on the outer surface of the copper tube 11. A threaded hole matching the thread on the surface of the copper tube 11 is opened inside the connecting block 10, so that when the copper tube 11 rotates, it can slide, so that it can be inserted into the bearing seat through the through hole reserved on the bearing seat and contact the bearing. A chamber 3 is opened inside the base 1, and a first detection mechanism is arranged inside the chamber 3. A second detection mechanism is arranged inside the copper tube 11. The first detection mechanism and the second detection mechanism work independently of each other, so as to detect multiple groups of data, ensure the accuracy of temperature detection, and avoid errors in detection due to the failure of a certain internal part.

[0024] Specifically, the installation mechanism includes a fixing plate 2 and installation holes 18. The fixing plate 2 is provided at both the left and right ends of the base 1. Installation holes 18 are opened on the outer surfaces of the bottoms of the two fixing plates 2. By attaching the fixing plate 2 to the surface of the bearing shaft and then inserting bolts to fix it on the bearing seat, the device can be stably fixed.

[0025] Further, the first detection mechanism includes a heat conducting block 6 and a first temperature sensor 7. There are two heat conducting blocks 6 symmetrically arranged on the left and right inside the chamber 3. The first temperature sensors 7 are installed on the outer surfaces of both heat conducting blocks 6. When the copper tube 11 is inserted into contact with the bearing, it will conduct heat, causing the heat to be transferred to the heat conducting block 6 and then detected by the first temperature sensor 7. The first temperature sensor 7 is connected to an external display device through a lead-out wire.

[0026] Further, a groove 4 is provided above the chamber 3, and a fixing hole 5 is reserved inside the groove 4. A baffle 8 is provided on the front side of the groove 4. A fixing bolt 9 is inserted through the top of the baffle 8. By fitting the baffle 8 into the groove 4 and then inserting the fixing bolt 9 and cooperating with the fixing hole 5, the baffle 8 can be stably fixed.

[0027] Further, the second detection mechanism includes a heat conducting rod 16 and a second temperature sensor 17. The heat conducting rod 16 is inserted inside the copper tube 11, and the second temperature sensor 17 is inserted inside the heat conducting rod 16, and the bottom ends of the second temperature sensor 17 and the heat conducting rod 16 are flush. After the copper tube 11 is inserted, the second temperature sensor 17 will directly contact the bearing to perform temperature detection. At the same time, the second temperature sensor 17 is also connected to an external display device through a lead-out wire.

[0028] Further, a spring 15 is connected to the upper surface of the heat conducting rod 16, and the other end of the spring 15 is connected to a pressure sensor 14. The surface of the spring 15 is sprayed with a heat insulation coating. When the heat conducting rod 16 and the second temperature sensor 17 contact the bearing, they will squeeze the spring 15, causing the pressure sensor 14 to sense the pressure signal. In this way, it can be detected whether the heat conducting rod 16 and the second temperature sensor 17 are stably in contact with the bearing.

[0029] Furthermore, the outer surface of the pressure sensor 14 is wrapped with a rotating handle 12, and the bottom end of the rotating handle 12 is connected to the outer surface of the copper tube 11. An indicator light 13 is installed on the front surface of the rotating handle 12, and the indicator light 13 is electrically connected to the pressure sensor 14. The surface of the rotating handle 12 is sprayed with a heat insulation coating. By rotating the rotating handle 12, the copper tube 11 can be controlled to rotate. At the same time, it can be known whether the pressure sensor 14 senses the pressure signal by whether the indicator light 13 on its surface lights up.

[0030] The usage method of this embodiment is as follows: Attach the fixed plate 2 to the surface of the bearing shaft, and then insert bolts to fix it on the bearing housing, so that the device is stably fixed. Then rotate the handle 12 to control the rotation of the copper tube 11, and insert it into the bearing housing through the through hole reserved on the bearing housing and contact the bearing. At this time, the pressure sensor 14 senses the pressure signal and the indicator light 13 lights up, indicating that the device is completely installed. At this time, the second temperature sensor 17 will directly contact the bearing to perform temperature detection. At the same time, when the copper tube 11 is inserted and contacts the bearing, it will conduct heat, causing the heat to be transferred to the heat conduction block 6 and then detected by the first temperature sensor 7, so as to obtain multiple groups of detection data.

[0031] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
